Stitch foundation with loose formwork. Foundation made of rigid formwork made of expanded polystyrene Materials for rigid formwork

As an unknown formwork for the construction of monolithic structures, it is often called polyfoam. The solidification of this material in the casting molds allows not only to create manually fluid elements for molding the CBV, but also to solve the same problem that is urgent for reinforced concrete structures, such as insulation. At the same time, the price of polystyrene polystyrene blocks is low, so making wall formwork from this material is not only functional, but also economical.

Extruded polystyrene

For the production of filling blocks, extruded polystyrene is used. This material is formed from polystyrene at a low temperature; the elements are formed using an additional extrusion machine.

Extruded polystyrene foam has low thermal conductivity, good water permeability, and also provides sound insulation. The material is good at absorbing pressure, durable (long term of operation - up to 100 years), which allows it to be used for thermal insulation and the production of vibration pads. The power of expanded polystyrene to save heat accounts for its wide use in everyday life: formwork for foundations, thermal insulation of facades, foundations, foundations, walls and re-crete formwork. In some cases, it can be treated without additional waterproofing. The filling blocks are also made up of so-called sandwich panels, with an internal heat-insulating ball in polystyrene foam boards.

Expanded polystyrene facade

To insulate the facades, slabs of laminated polystyrene are used, and plaster or different canopies can be applied over the installed elements. This method of thermal insulation will especially often stagnate in these situations, if it is necessary to eliminate the thermal protection of an already finished unit, for example, when insulating the external walls of adjacent apartments in panel booths.

In addition to purely utilitarian purposes, the facade is also used for the creation of decorative elements of decoration - cornices, friezes, capitals, rosettes, columns, locks, pedestals and other linings. To install both slabs (blocks) and decorative elements from extruded polystyrene foam, an adhesive (for other products from the Knauf company, for example) and a mechanical fastening method are used. Decorative elements, as well as thermally insulating blocks, can be covered with plaster or porcelain.

Formwork of slabs on volumetric posts

One of the ways to solidify polystyrene foam for pouring slabs is to use standard blocks that are installed in one system when supporting volumetric racks are installed.

A classic version of the shape for the foundation and walls of monolithic booths has a time-sensitive design, which is made from wood and chipboard. Invisible formwork made of expanded polystyrene is an alternative method of construction that does not make the exits visible. This design increases the value and promotes energy efficiency, acting as thermal insulation. However, such material has some peculiarities that cannot be ignored.

Developers of this material indicate a complete advantage, compared with standard options for permanent formwork. These advantages need to be known to every person who wants to quickly use a different type of construction made from expanded polystyrene.

The advantage of concrete formwork made from this material lies in the fact that such a design has additional functions. The main one is the organization of the form for the walls and foundation of a monolithic building. Due to its physical properties, expanded polystyrene is a great insulator. It is very important that the formwork of this type cannot be dismantled once it is covered with concrete.

When boards for formwork are vicorized, the stinks impede dismantling. Wood is not insulating, so polystyrene blocks are used as the most important inserts. The invisible formwork of this material allows for the construction of a lightweight concrete structure. Moreover, this type saves 30-35% more heat, less than its analogue from the red target. Thus, the use of expanded polystyrene allows one to reduce costs for other materials used for laying foundations or walls.

An alternative to polystyrene forms is plastic formwork. The price for such a design of a thing, however, is highly competitive. Unknown plastic elements can be purchased at your convenience store or you can order them online.

Another advantage of such forms is that they protect the concrete against moisture. The collection is especially respectful. As a result of using polystyrene foam blocks, the service life of the foundation and walls will increase by approximately 20%. Often this very fact encourages people to use such formwork for everyday use. Various elements (in terms of shape and dimensions) are formed into polystyrene foam.

Increase your respect! The production of polystyrene molds reduces financial costs by approximately a third.

The price of re-crete formwork made from expanded polystyrene is usually the primary factor in its selection. However, the greatest strength of such forms are those that when frozen, they preserve the structure of concrete at low temperatures (not lower than +5 °C). The concrete of this type is harder in normal conditions, so it bounces positively on its surface after being caught.

However, pouring concrete material into a wooden form gives a completely different result. In such formworks (at low temperatures), the concrete becomes harder, and its structure collapses.

Unknown formwork made of expanded polystyrene: shortcomings of the structure

Similar structures have their shortcomings. The actions should be completed with the summaries. For example, one of the most serious disadvantages is the fact that the wake-up call for such formwork does not delay wake-up. Therefore, it is recommended to think about your design in advance. In addition, all communications that are involved in a dispute must be laid at the stage of everyday life.

A booth with an invisible formwork must adhere to certain rules, which must be adhered to very carefully, in order to avoid any conflict and resistance to unpleasant factors in an excessively common way. Blocks made from expanded polystyrene will require stacking. It is very important to maintain tightness, so that in other cases the vologist will be less penetrable.

Another shortcoming of this technology for the creation of vital spores lies in the fact that polystyrene foam forms cannot be treated at temperatures below 5 °C. In such a situation, concrete simply cannot be hardened. In sintered concrete, it requires additional curing, so in other cases it would be incorrect.

Varto also means that the blocks of rigid formwork, made from expanded polystyrene, are subject to normal ventilation of the concrete structure. The main problem in this regard lies with the installation of ventilation communications. This Primus system ensures the necessary ventilation, while maintaining a high efficiency factor of an unobtrusive design.

Views of unknown formworksdepending on the material of preparation

Before starting installation, it is necessary to consider the different options of permanent formwork that can be added to the daily market. The main feature by which the classification of these viruses is determined is the material of preparation. The choice of choice depends on the complexity of the future debate and individual characteristics. Let's take a look at what kind of materials are most often used to make concrete forms.

Expanded polystyrene. Lots of people rely on food that is expanded polystyrene. This material is a standard material, which is used in the manufacture of permanent formwork. Another name for expanded polystyrene is gas-filled polystyrene. Wine is characterized by a number of positive qualities, which indicate the popularity of vicorized forms prepared from it.

Corrisna information! Expanded polystyrene has high strength properties and provides reliable thermal insulation for concrete.

Arbolit. This material includes 2 main components: wood shavings and concrete. Surrounding the elements of the invisible formwork made of arbolite are represented by blocks. There are empty gaps that are reinforced and filled with rubbish during installation. The advantage of this cheese lies in the fact that it has a high value. The soundproofing properties of wood concrete are also its strong point. The disadvantages of this material, which is used for the production of formwork, are low thermal insulation and high varnish.

Fibrolite. This milk, like the front, consists of 2 components. The first is wood shavings, which provide the fibrous structure of the surrounding elements of such formwork. Another component of ideas is inorganic viscous speech. The main advantage of such formwork is its resistance to extreme temperatures.

Dribnocement. Such material is considered less popular, less overused and more suitable for permanent formwork. The chip-cement installation technology has its own nuances. The advantages of this material include very good sound insulation and resistance to temperature fluctuations.

Economical option: invisible formwork with Pinoplex

Today it is possible to install permanent formwork from polyplex slabs. This option allows you to add more extensions, allowing you to significantly protect your finances when you are awake. Pinoplex is a material that is vicorized for insulation and has good thermal properties. This allows you to set it like a concrete form.

Pinoplex slabs have dimensions of 60x100 cm. The dimensions of these panels exceed the parameters of standard structures made from polystyrene. In order to install formwork next to a booth made of Pinoplex, it is necessary to select the correct size of the material. It is also important to understand that such viruses do not contain any volatile fixative elements. Therefore, before purchasing material, it is necessary to think over a system for fastening adjacent parts to each other.

The use of Pinoplex allows you to reduce financial costs to a minimum. It is especially clear that they are equalized with expenses necessary for the creation of a standard design. Formwork for ceilings on telescopic posts, wall panels and veneer plywood will be much more expensive.

Corrisna information! The most extensive option for organizing fastening parts is the installation of special jumpers, which are equipped with splits along the edges. Such elements are prepared from reinforcement. The main thing that needs to be remembered is that the installation of such jumpers is carried out between pinoplex slabs.

This type of construction is less expensive and is also easier to use through the selection of fasteners. The price of simple formwork made from polystyrene foam, but its installation does not require any special steps. Depending on your needs, you can add fixing agents for slabs with polystyrene foam to prevent stiffening during installation of the polystyrene foam structure.

Unknown formwork made of polystyrene foam: different types of structural parts

Formwork elements can form a different structure, depending on their operational purposes. Today there are such variants of viruses that are prepared from expanded polystyrene:

• panels;

• blocks (lite and collected);
• frame systems.

Systems that are placed next to frame structures are double-circuit structures, between the walls of which empty space is created. During installation, reinforcement is laid in the middle of such formwork and the cracks are poured. If you take a section of the finished wall prepared using this technology, you will see three balls: the outer two, represented by formwork, and the middle one, made of reinforced concrete.

Polyfoam blocks are divided into two large groups: cast and prefabricated. Before the time of assembling the formwork, these elements are cleaned in such an order that the stench is removed one by one. Moreover, for sticking, do not use any substances that you spit (for example, glue). The placement of blocks follows a checkerboard order.

Lithium is called a thermoblock. This means that stench can reach high thickness (up to 40 kg/m³). The peculiarities of the structure influence the thermal insulation power. A block of this type consists of 2 sheets, which are joined together using special jumpers. The folding of such parts and the joining of their surrounding elements is carried out at the preparation stage. Such designs have one drawback: they warm up slowly. This is due to the removal of insulation from the inner side of the wall pie.

The dimensions of blocks of cast formwork made of polystyrene foam may vary. However, the standard option is a box with dimensions of 1000x250x250 mm. The weight of such a block is usually close to 1 kg. The thickness of the insulation material, splayed along the sides (sides), is 50 mm. Apparently, this dimension of the concrete ball will be 150 mm.

How it works for strip and slab types. Use the report stock in reinforcement darts for the foundation.

Insulation in forms that are used for pouring concrete can be different. When choosing an insulator material, the current characteristics of the structure should be taken into account. It is important to remember that such a search engine has two main functions. One of them is form-building, and the other is heat-insulating. The type of blocks varies depending on the type of polystyrene foam. How many different types of forms are there? The price depends on the quality of the insulation ball's design and quality.

Increase your respect! It is not recommended to carry out concrete pouring below the 3rd row. The ideal option would be to lay the concrete in 2.5 rows, since in this case the seam will be placed in the middle of the block.

Prefabricated polystyrene foam blocks for formwork

The formwork can be represented by prefabricated elements, which are formed from the cast with their own structure and have different curing properties. Such blocks are made from two sheets, which are assembled into a single structure before starting the assembly work. Such elements can be prepared not only from expanded polystyrene, but also from other materials. The distance between 1 and 2 sheets becomes permanent due to the use of special components called spacers.

The construction of a booth with an invisible formwork of this type has a number of features that require respect. The main advantage of prefabricated forms lies in the fact that their freezing allows you to place more than three balls against the walls. Moreover, the combination of materials never plays a role, since they were formed with the help of cast blocks to ensure a clear consistency of the materials. Insulation in such a situation will always be called upon.

More advanced solutions include a wall pier, which includes two facing balls made of rigid sheet material. Insulation material (expanded polystyrene) is placed against the outer sheet of this type. The other ball in this situation is concrete.

The project for a booth with an invisible formwork is being prepared in advance. It contains all the necessary data to indicate the design features, dimensions and individual solutions depending on the situation.

Varto points out that such forms have one fundamental advantage over cast analogues. The point is that, if necessary, you can change the width of the internal empty part, in which the fittings are placed and the damage is poured. The change of this display is carried out in front of the stagnant spreaders. If there is no such need, additional locking elements can be added.

All expenses must be indicated at the cost of the formwork. Devices, ratings, dimensions of other elements - everything is recommended to be specified in the front mounting diagram.

The design features of prefabricated forms depend on the heating of the wall. The presence of polystyrene foam allows you to increase this appearance. In times of need, various designs that are used for everyday life can be created with your own hands.

Installation of formwork for a strip foundation: installation features

The most popular type of foundation that is used in the independent life of buds and other spores is strichkovy. Before starting to organize such a stand, it is necessary to carry out the necessary preparations. They include the development of the project and the preparation of the future Maidan. Beyond this, it is necessary to define the layout of the place dedicated to everyday life.

The installation of formwork for a strip foundation does not require any special folding, but there are several nuances that need to be known and addressed. For example, it is recommended to fill in a ball-by-ball manner. The process itself is carried out in the following way: the empty material at the block is crushed into concrete, after which it is impossible to wait for it to be caught.

Corrisna information! The organization of the fittings is not a comprehensive one. It fits into the situation where there is a need for greater structural value characteristics.

The reinforcement is tied in the middle of the block elements. There is no need to dismantle the expanded polystyrene, as the fragments will lose the function of the insulation unit. Before starting to pour the cement, it is necessary to check the accuracy of the placement of the blocks in the ditch.

In times of need, formwork for a foundation made of expanded polystyrene requires the use of additional elements. It is very important to achieve the correct geometry of the base. This technology has many advantages. With the use of small blocks made from expanded polystyrene, the cost of organizing the foundation is reduced by at least a third.

Formwork for monolithic foundation: DIY installation steps

After organizing the foundation of the new building, the installation of formwork can begin. This operation is mentally divided into three stages: installing blocks, knitting reinforcement and pouring. The skin stage is strictly consistent with the relevant norms and rules. As work progresses, it is necessary to improve safety techniques. Let's take a look at the skin stage of the report.

Installation of blocks. The first row of forms is now being installed so that the concrete is poured into the concrete. Please note that the installation is only done on a hydroisolated surface of the base. Formwork for foundations made of expanded polystyrene can be firmly fixed to the frame of the reinforcement bars. These elements are a perfect bond between the base and the same formwork.

Fakhivts are happy to check the accuracy of the finished work, so that it is possible to improve the design of the original dimensions. The identification of the location of the leads for the partitions is also an important moment that requires respect. After organizing the first row, you can print the arrangement of the other. The technology for installing blocks transfers to the checker system, in which the advancing row is shifted to the front one. As a result, the stack of elements of the first row may be lost in the middle of the block of another layer.

Knitting reinforcement. Installation of a metal structure is one of the most important moments in organizing any type of cake. The reinforcement is used for strengthening foundations, walls and monolithic slabs. The formwork for the foundation, which is made up of blocks that are laid in rows, is girded around the perimeter with runners, spread out in a horizontal plane.

In order to simplify the installation of the fittings, the skin block has special grooves located at the jumpers (internal). Horizontal rods are mounted in such a way that the skin of the advancing element overlaps the front one (overlapping). Then the rods are connected to each other, as well as to the vertical elements through an additional special structure.

Increase your respect! Reinforcement allows not only to increase the strength of the structure, but also to reduce the pressure of cement on the form.

Pouring the Rozchina. Before starting to pour the permanent formwork with your own hands, it is recommended to lay pipes in the middle of the structure that is being formed. Cement cement, which is used for molding formwork, is not liable to contain third-party additives and materials (for example, crushed stone). The operation itself is quite simple. The pouring is done step by step, and the height of the concrete ball may exceed 1 m. This figure corresponds to the size of 3-4 small blocks of the structure.

The price of permanent formwork for foundations is lower than that of standard analogues, such as vicorized plywood and planks. It is important to remember that spilled soil requires destruction. For which a special tool is needed - a vibrator. Whenever there is a need for electrical installation, you can quickly fix it with a spade shovel.

Invisible formwork for walls: rolling technology

The independent development of such a technique for casting walls contributes to the understanding of the technological process. Most often, this type of housing is used by non-professionals in the construction of private single-surface booths, as well as garage structures. Formwork made from expanded polystyrene can be constructed one at a time. However, a number of people decide to install walls much more quickly.

The advantage of using polystyrene polystyrene forms lies in the fact that the stench is not significant. Also, physical demands are often reduced to a minimum. Before starting work, it is necessary to learn the step-by-step algorithm of action and nuances that allow you to learn about how to properly construct the formwork.

Walls prepared using this method are recommended to be installed on a foundation. This basis is best suited for working with various polyfoam forms. It is important to remember that pouring cement for pouring walls often imposes tension on a number of rows of blocks. Fahivtsi produce 4 rows of forms, and the culprits are reliably connected with the basis of the spores behind the additional fittings.

Corrisna information! It is not recommended to pour all the concrete at once. From the beginning, apply a partial fill and mark for an hour, which is necessary for shrinking the crack. As a rule, this procedure takes a little more than 3-4 years. Next comes the addition of cement.

When creating monolithic spores for pouring walls, special shapes are often used - shields. They use special bolts and create a gap into which the concrete is poured. Such viruses can be of different sizes. For example, its maximum height is 3.3 m, and its width ranges from 0.25 to 2.4 m. Once damaged, this structure is dismantled. The size of the formwork shield is selected depending on the individual characteristics of the plant being constructed.

Another feature of the flexible formwork that is used for pouring walls is its instability. This is due to the fact that the concrete that is poured into the mold takes a lot of weight. Thus, installing blocks, laid in 4 rows and equipped with reinforcement, will require additional strengthening. What time is enough for the rift to settle and calm down?

When installing small blocks made from expanded polystyrene, it is necessary to pay special attention to their construction. The structural elements must be joined together with special reinforcement so that the surface of the first rows is as even as possible. Otherwise, when additional rows are added, the wall may collapse due to their distortion.

An alternative to expanded polystyrene is plastic. Plastic formwork for monolithic buildings is used in order to ensure good strength and rigidity of the structure. The advantage of such viruses is that they have a high wear resistance.

Facing robots allow you to not only give the walls, formed in the formwork form, a complete look, but also enhance their drying characteristics. Improvement can be carried out practically on all types of structures. After flooding the walls, it is usually necessary to clean it daily. This refers to the design of the forms. In this way, there is a need to apply a thick ball of plaster.

Save on the finishing touches of walls and other surfaces, which will not work, and the waste of the work will be reduced for the cost of polystyrene polystyrene. The price of this material is much lower than that of traditional formwork options.

Most often, to decorate the wall, a special mesh is sufficient, which can be made from glass fiber or metal. Such a mesh is adhered to a concrete surface behind an additional adhesive layer, after which it is covered with plaster or putty.

In this way, not only standard rectangular walls, but also round columns are formed. The formwork for such structures is most often made of plastic. There are also cardboard variants of forms.

Increase your respect! In addition to standard methods of processing the external surface of concrete, there are other, no less popular options. For example, very often, as a facing, stone and piece stone become stagnant.

For the internal finishing of walls, gypsum cardboard material is usually used. Installation of gypsum boards can be done in two ways using either profile elements or glue. This method of cladding is already popular not only because of its simplicity and effectiveness, but also because this material provides good sound insulation.

Racks for organizing unobtrusive forms of overlaps

The traditional option for organizing overlaps in monolithic or other structures involves the installation of special telescopic (universal) stands. These are vicorized to fix the temporary flooring, which is made from plywood for formwork. This method is not easy, as it will require a lot of time and a lot of physical effort.

The stand, which plays a supporting role, is made up of many structural elements. The lower part of the telescopic vibrator is equipped with a tripod, which ensures the stability of the pipe. The upper part of the drawer has a special nozzle, which is necessary for burying and tidying the side beam - crossbar. All racks for slab formwork are divided into two categories, depending on the distribution of parts. Some of them are equipped with open slots, while others are closed.

The pipe, which has a smaller overcut, is exposed to special openings throughout its life. The opening length can be varied - from 11 to 17.5 cm. The outer pipe interferes with the support nut. As a result, if there is a need to fix the stand on the singing surface, a special earring is inserted through the openings in the pipes. This element has a support (nut), which is adjusted to the required position.

Telescopic posts for formwork can be made in different sizes. This figure ranges from 1.7 to 4.5 m. The stinks can be seen in large quantities (up to 4 tons). Please note that such support frames are made of metal, so they are coated with special anti-corrosion coatings, since the steel may rust.

Unknown formwork for slabs: features and characteristics

Instead of the standard method, which conveys the appearance of support posts, polystyrene foam formwork for slabs uses a completely different installation technology. As the basis for such a system, special matrices are used, which are made from polystyrene and polystyrene.

Similar matrices of traces are laid on load-bearing walls. The advantage of this method is that the elements have a small mass, so their installation does not require serious physical effort.

Increase your respect! Before starting the work, it is necessary to unscrew the formwork.

The sticky matrix fits together easily. The leather belt is equipped with a tongue-and-groove system for connection. In this way, such an installation can be installed by any human being, who does not want to know about the work of this gal. Thanks to the tongue-and-groove system, there is the possibility of a fluid organization of the flooring.

Such formwork for monolithic slabs is capable of forming a ball of concrete up to 15 cm thick. As a rule, this value is entirely sufficient to organize a reliable structure. Before you start pouring concrete, it is necessary to move the reinforcement between the joint zones of the overlap elements. The metal frame must be assembled into a continuous beam, which occupies the entire width of the gap.

Then the animal matrix needs to remove the reinforcing mesh. It is formed into rods, the diameter of which is 10 to 15 mm. Knitting of reinforcement is carried out in the traditional way - with the help of a special drill.

The final stage of the volumetric formwork of the slabs is the pouring of concrete, after which it is necessary to ensure that it is finished. This is how the organization of re-creation is carried out using additional polystyrene matrices. The result of this process is a unique design that creates significant value.

Once the cement has been damaged, the formwork, made from expanded polystyrene, cannot be dismantled. It loses its pyrolysis and from this moment begins to lose its thermal insulation function. This method of organizing the structure is technologically advanced, as compared to the traditional method, which involves laying out the vertical beams for the formwork of the slabs.

It is important to remember that the self-sufficiency of such technology will require understanding and nuances. It is important to know even before starting work that the placement of overlapped elements will require care. Any design changes or displacement of blocks during their placement can lead to collapse of the structure.

Unknown formwork: pricesat the current market

The quality of blocks is an important moment to maintain respect. The price of building blocks, from which permanent formwork is constructed, is influenced by two key factors:

• thickness of expanded polystyrene;
• dimensions of parts.

The price of permanent formwork for a polystyrene polystyrene foundation is subject to a long-term cost. When selecting other elements of the molded structure, it is recommended to pay attention to their strength. This feature contributes to the durability of the vise design. The thicker the details, the more obvious the stench can become noticeable.

Increase your respect! Fakhivts are pleased to produce blocks, the thickness of which varies between 25 and 35 kg/m³.

The average cost of a block made from expanded polystyrene is approximately 160 rubles. Varto vrahuvat that this price is confirmed by the dimensions of 1500x250x250 mm, which have a thickness indicator of 30 kg/m³. Designs with a height of 1.5 m have an adjustment function for the installation of jumpers of different sizes (15-25 cm). Virobi, dovzhina for installing 1 m, the cost is cheaper - about 130 rubles. for one piece

If it is planned to use standard operating technology, it is recommended to consider the quality of various materials. The price of telescopic stands depends on the features of their design and manufacturing company. Currently, these supporting elements can be added for 500-5000 rubles. It is not recommended to buy the cheapest materials and tools, as they are often characterized by low technical characteristics.

The supporting elements are vicorized to strengthen the wooden structure, which is made from laminated plywood for formwork. The price of 1 arch of such material varies between 600 and 3000 rubles.

Unknown forms are a great alternative to standard structures, such as those made from wood or plywood. Such formwork allows you to pour concrete and serve as a reliable heat-insulating material. It will actively stagnate in private everyday life, which will require updating the installation instructions and updating the safety rules.

Monolithic everyday life with a series of unknown formworks, regardless of the long history, has become widespread not so long ago. It is no less true that methods of daily living are gaining more and more popularity. The formwork should be made from different materials, but the most suitable formwork in practical terms is polystyrene foam formwork. More correctly called polystyrene formwork, polystyrene foam is a type of polystyrene.

Unknown formwork made of expanded polystyrene

Another broad name is penoplex, which is a trademark of the same polystyrene foam; the manufacturer produces under this brand polystyrene boards for insulation of walls and as permanent formwork. If you are interested in “Pinoplex formwork”, you are wondering how to make formwork with Pinoplex with your own hands – Continue reading the article, the very same thing to tickle you.

Types of flexible formwork made from expanded polystyrene

The polystyrene foam formwork is available in several variants.

• Empty blocks made of polystyrene with significant and insignificant stiffening ribs, which resemble blocks from a children's LEGO construction set. Upon completion, a composite wall is made from reinforced concrete and expanded polystyrene, which is easy to plaster and peel off. The block formwork will be widely stacked before the construction of the load-bearing walls.
• Unknown polystyrene foam formwork.
• Reinforced polystyrene panels made from 10 to 250 mm, reinforced with reinforcing mesh. The basement wall can be easily concreted using a sprinkler path.

Blocks for curved formwork

In addition to these basic types, expanded polystyrene blocks with curved geometry are produced, which allows for non-standard architecture.

Dimensions of small formwork made of polystyrene foam

Advantages of polystyrene foam formwork for walls and foundations

• Polyfoam has high thermal insulation power, resulting in wall insulation that provides wonderful sound insulation.
• The content of this material can be reached without any delay (subject to sufficient evidence).
• Polystyrene foam formwork for the foundation allows you to make this most important structural element of the cabin energy-saving and warm.
• Polyfoam protects walls from fungi, rot, and is not afraid of termites;
• The low price of the blocks makes the technology the perfect choice for those who are looking for the optimal balance between price and efficiency.

To some extent, the method can be attributed to the inability to carry out routine work and the difficulty of mastering. Foam plastic is dielectric, it is necessary to firmly ground the booth.

Next, choose contractors who will work on such a technology - cumbersome, but different from others. In addition, living conditions in the premises mean high moisture content - it is necessary to control the primus ventilation.

Unknown formwork made from polystyrene foam with your own hands - technology, subtleties and nuances

How is expanded polystyrene formwork prepared? The technological process for installing skin alarms.

If this is not necessary, it can be done using several rows of solid masonry. The foundation of the foundation may be accurate, so it would not be possible to level it with blocks for a piece of work. Waterproofing is laid on the foundation and then the laying of blocks proceeds.

• The first row of blocks rests on vertical reinforcement as they emerge from the foundation. After completing the placement of the first ball, the reinforcement bars are again placed in the grooves of the blocks (horizontally). The construction of formwork uphill is carried out similarly to LEGO bricks, however, it is necessary to carefully follow the vertical alignment.
• After three or four rows of polystyrene foam blocks, pouring begins with an indispensable clay vibrator or manually. Fill half the top row of blocks.
• All communications must be routed through the openings on the walls before the concrete is poured.

The result is a sandwich-type wall structure, two expanded polystyrene balls, and a monolith between them.

How to unlock the quality of life?

To determine the quality of erection of permanent formwork from polystyrene, it is necessary to take the current level of available materials:

• Formwork block- 3.3 pieces per 1 sq. m.
• Concrete- 0.12 cubic meters per 1 sq. m.
• Armature- Close to 10 kilograms per 1 sq. m.

Expanded polystyrene material is soft, lightweight, and protects its traces from the sun and wind. Especially in the wind - so that you don’t have to collect blocks all over the area.

A typical solution that resembles the incomprehensible essence of the technology and the banal incomprehension of the weight of concrete: assemble polystyrene foam formwork for the entire height of the wall, pour 20 tons of concrete, pour a monolithic concrete in one day dinok. It’s not possible to work like that – this method won’t work for everyone.

Other popular types of rigid formwork

In addition to expanded polystyrene, there are a number of materials that can be used to form stable formwork during monolithic construction.

• Expanded clay concrete construction is expensive and outdated.
• Cracked magnesite formwork – it is important to freeze for pouring internal partitions.
• Arbolite formwork with shavings and cement. Excellent material, but such constructions are expensive.

At the end of this list, we can say that polystyrene foam formwork is today the cheapest option when staying up to date with new technologies - it is simple, cost-effective and a wonderful insulator for the next wall.

Video of installation of polystyrene formwork

Today, energy-efficient technologies are gaining more and more popularity. In a modern monolithic house building, there are two main types of installation of concrete formwork: low-grade and high-grade. Unknown formwork has recently become commonplace in everyday life, and expanded polystyrene has become the most popular material for these works.

Materials for rigid formwork

The most commonly used material is sheet extruded expanded polystyrene EPPS. It has a high value and rigidity for leveled and large blocks of flexible formwork for foundations made of polystyrene foam. However, for the installation of reliable EPPS formwork, certain elements are required. For these purposes, a universal plastic screed from the SBD company is suitable, as fastenings for reliable connection of formwork walls for foundations of various types with the subsequent installation of reinforcement and pouring of concrete.

With the help of additional screws, it is possible to create formwork from EPS sheets with a surface of unbounded size and there will be both internal and external parts, on top of blocks of independent formwork, such as fixed dimensions and insufficient communication between each other. Often, with a very neat concrete bath, there is an uncontrolled curvature of the formwork surface or the opening of irregular rows of polystyrene foam blocks.

Now the bonded EPS is not exposed to high temperatures and drying times, as with traditional gluing. All you have to do is insert the screw into the bit of the screwdriver and tighten it - the connection is ready. Vikorist screw of high quality, low quality EPPS sheets for formwork, when concreted, remove reliable connection with a concrete core.

Advantages of plastic screeds

Plastic screed SBD can be used in a number of ways compared to traditional concrete formwork; First of all, precisely, both the internal and external dimensions are fixed with a simple hand-held structure, which allows the robot to handle the screw. Other advantages:

• Easy to install.
• Changes in time to pick up.
• Shorten the hour for the wake-up call.
• Possibility combine the outer polystyrene foam formwork wall with other sheet materials for the inner wall. The materials may include DSP, SCP, fiberboard, flat slate, plywood, chipboard, OSB and other materials.
• Corrosion resistance.
• The presence of “cold areas” in the finished structure.

What's the fuss? expanded polystyrene Not only can you set up a wake-up call in a short period of time, but it has enhanced thermal insulation, does not allow outside sounds to pass through, and has high moisture permeability and durability.

Making a booth with expanded polystyrene is like a child's game with cubes. You need to stack the cubes one on top in two rows with a small gap between them, and then pour cement into this gap.

Few pieces of loose formwork

The main disadvantage of this innovative method in everyday life is the price. Few people analyze the advantages of this technology, unless Podsumkova price for two items against other materials. In addition to the price, there is another major disadvantage - the lack of waterproofing. After building the foundation, it is necessary to carry out cementation.

Expanded polystyrene will be required protect from wasting direct sleepy exchanges, otherwise it will quickly collapse. The visible part of the foundation is not allowed to lose its outer appearance, but as a rule, do not touch the part of the foundation that is under the ground.

Ranges of thickness of concrete parts

The thickness range of the concrete part should be 100 to 200 mm with a margin of 50 mm. Tse:

• internal partitions;
• bearing walls;
• lighter foundation.

For example, a wall of 150 mm allows you to build a height of up to 8 surfaces, in seismic-proof areas. The compaction of the universal screed with a rubber seal allows you to expand the thickness of the concrete part from 300 to 600 mm with a edge of 50 mm. We're talking about highly constructed, load-bearing walls and foundations.

Innovation in everyday life

During the period of 2013, qualified development organizations in Moscow, Samara, Nizhny Novgorod, Kazan, Chelyabinsk, Rostov and other great places carried out tests on real-life objects. The fastenings from the SBD company received high marks for the strength and ease of installation.

In addition to the traditional fastening of thermal insulation, the treasure trove of innovative wines has appeared reinforcement fastening clip. With this, you can also connect a piece of reinforcement perpendicularly to each other for further pouring with concrete. With this process, the folding of the frame and composite reinforcement has become so simple that it can be used as a guide to a person’s everyday life.

Supply price

The formwork for the foundation is insignificant, the price is not lower than other materials created for everyday life. For example, the most popular material for the price is gas silicate blocks, which are even lighter, allow external sounds to pass through and have low thermal conductivity. Gas silicate blocks are filled with quartz sand, and cement is required for their connection.

When you are a vikorist unknown formwork You will create a monolithic wall and insulate it on both sides with expanded polystyrene. As a result, you will not be able to equalize the walls after the creation, which cannot be said about other materials. After waking up, you will significantly save on internal processing. You will not have the opportunity to plaster the wall, there will be fragments and thus ideal geometry. For black finishing, you can paint plasterboard, which is attached to the wall using basic adhesive.

Therefore, you will not spare at the initial stage of construction, fragments of cement and expanded polystyrene will require greater losses, lower gas silicate blocks or wholes, or high indicators of unchangeable formwork to the foundation, it is better to overpay for chattku budіvnitsa, sparing on distant robots.

Laying the foundation is one of the most important stages of everyday life. Even though all of these robots are based on the safety and trouble-free operation of the booth. The main building material for the foundation is most often concrete, which can be formed in two ways: in the form of ready-made reinforced concrete blocks or in the form of a monolithic structure, which is being debated in the minds of everyday life.

Another option is used more often, because its versatility allows you to create a structure of any dimensions, both in height and in width, just as the foundation blocks are of standard dimensions.

It is impossible to build a monolithic foundation without the use of temporary formwork, the main components of which are the thinning of the rare concrete mixture as it spreads over time until the concrete gains the necessary value.

After this, the formwork is removed and transferred to another plot for pouring the foundation.

When creating private buildings, where self-propulsion is especially carried out, disposable wooden formwork is most often used. When it comes to commercial life, it is important to install steel formwork, as it serves many resources.

The advent of new materials and technologies has led to the emergence of structures that make it possible to build a foundation without further removal of formwork, which saves time and improves the characteristics of the foundation. This type of formwork is called “immense”.

The unknown formwork is guilty of such pitfalls:

• low quality, otherwise it will become economically ineffective;
• the value is sufficient to ventilate the rare concrete sack that is bursting;
• durability;
• Ease of installation.

Elements of permanent formwork are vibrated in two types:

• volumetric elements of unchangeable shape and dimensions, which clearly define the geometric characteristics of the future foundation (scale – width);
• besides elements that allow you to sufficiently change the dimensions of the foundation line by collecting formwork of different widths and heights.

Depending on the variety that is produced in the vibrator plant, the formwork can be divided into many types.

Types in staleness:

• from cement-bonded particle boards;
• from fiberboard;
• from wood concrete;
• from expanded polystyrene.

Polystyrene foam has recently become even more popular among private clients, not only for poured foundations, but also as formwork for building walls.

Vykoristovanie for this production material for the preparation of bags. However, depending on the technology for the production of polystyrene foam, there are two types of material that differ not only from the outside world, but also from the authorities - polyfoam and extruded polystyrene (EPS).

Polyfoam is more barred, and extruded polystyrene is available in colors - orange, gray, blue.

Polyfoam when compared with other materials has the following advantages:

• resistance to microorganisms;
• the payload is small, which reduces transportation costs;
• high thermal insulation characteristics;
• The process of assembling formwork is easy and quick.

Here are some shortcomings in the material and content:

• low cost, which ensures accuracy when folding formwork and pouring concrete;
• the ability to take shape with a one-hour infusion of water and cold;
• sensitivity to UV radiation;
• You might get rid of rodents.

EPPS is a clear material, but also more expensive.

The wine has a higher value and is more resistant to unpleasant spills, therefore the term of its operation is greater.

• you can see the finished blocks;
• The sheets appear to be of standard sizes, which allows for the assembly of formwork around the surrounding elements.

The first option is simpler and simpler, especially since the dimensions of the foundation are approximately the same as the dimensions of the formwork blocks.

Ready PKS blocks are easy to assemble according to the design principle.

Hydration and shortcomings

Well, before the transition can be brought forward:

• shortening the terms of fundamental work up to 30%, which is important at waking hours in the autumn and winter periods;
• the structure is light and durable (with advanced technology of folding formwork and pouring concrete);
• concrete foundation from two sides insulated with polystyrene foam, which enhances its heat and sound insulation characteristics and enhances the thermal insulation stage of the foundation;
• standard factory formwork designs provide devices for laying reinforcement in the concrete body and technological openings for future communications;
• Being a soft material, PPS can often dampen the flow of heaving soils onto the foundation;
• The slots and recesses at the ends of the formwork blocks allow them to be quickly assembled in one place and create a virtually airtight space, reducing the risk of fresh concrete spreading.

It is also necessary to know the shortcomings of the PPS formwork so that you can minimize them and also avoid disappointment.

• The durability of expanded polystyrene is not very high (about 20 years). The basement part of the foundation is especially vulnerable because it is not protected by the soil and is therefore susceptible to atmospheric inflows.
• It is dangerous to see gas-like styrene, which is harmful to health, due to the heating of polystyrene foam. There is no problem with booths without basements, since the formwork does not interact with the microclimate of the booth. If the basement is planned, and therefore it is more important to burn it, then such formwork is not the best option, like polystyrene foam for plastering.
• Typically, polystyrene foam blocks have walls secured with metal or plastic clamps. In this way, the base of the foundation is not protected from the cold by a polystyrene foam ball, in order to achieve doubtful achievements of thermal insulation of the side walls of the foundation. Since it is critical for you to protect the foundation from the cold, then install the lowest row of formwork blocks from P-like elements in order to protect the foundation from the cold that comes from the side of the base.
• Foldability of pouring formwork with concrete. Polyfoam is still not the same kind of flooring material, so in order to fill it with concrete, you will have to fill the concrete with thin balls, and evenly over the entire area of ​​the foundation. In addition, it is better to sand the concrete with a different resin material - this will reduce the risk of damage to the damaged polystyrene foam.

The idea of ​​​​removing the invisible formwork is going to be spluttering, but will this method of building the foundation be completely abandoned in the future?

From which drive comes a blank thought. Some people who have tried this option become its biggest supporters and popularizers. There are other reasons for choosing other formwork options, some of them unknown.

So, what if it’s time to install PPS blocks in the frame of the formwork?

How should we study, what are the following options:

• Building a standard foundation for a small private booth. At the same time, as it is great and important, spending on the addition and assembly of small formwork threatens to remain solid, while the original wood can be removed from the completed work and lumber can be harvested from By a different method.
• When the foundation is built in the winter, polystyrene foam is a miraculous help - its heat-insulating power reduces the cost of warming up the concrete until its value increases several times. And if the foundation is not very voluminous, then it can be done without warming up (the fragments when the concrete is hardened seem to have enough heat).
• At about the hour of the meeting there was no basement. In addition to the exploited basement, there is a simple formwork of a combined type - on the outer side of the foundation there is a wall made of PPS, and on the inner side there is a cement-bonded particle board, which is safe for health.

In other cases, first of all, pay attention to the use of simple formwork, and then carefully consider its economical and environmental benefits.
