The foundation is made of lightweight polystyrene foam formwork. Features of permanent formwork for foundations Advantages and disadvantages of permanent 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 jointed EPS is not exposed to high temperatures and drying time, 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. It is necessary to stack the cubes one on top of another in two rows with a small gap between them, and then pour cement at 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 at the same time it is 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.

6. Armuvannya. I got good information from a cost-free book available for download on the Internet - “Low-buried stitch foundation” by Andriy Dachnik. I don’t know anything about the normal threads on the forum about the reinforcement of a string foundation. I've been searching for information for a long time. Є garna topic about armuvannya kutіv-http://www.forumhouse.ru/threads/122401/

When installing reinforcement, creating your own theme - Reinforcement is divided into late and transverse. Later - this is the long reinforcement that is laid along the foundation wall. Transverse - this is reinforcement that is laid across the wall to the foundation. Transverse is either vertical or horizontal. The transverse reinforcement (vertical + horizontal) was represented by bending clamps with reinforcement d=10 mm. The length of installation of clamps is 0.5 m.

The later one had 5 rows: the bottom and top 3 rods each d=16 mm, and the middle rows 2 rods each d=12 mm. Knitting drit d=1.2 mm (they took 10 kg at 55 rubles per 1 kg). We bought one knitting gag, one having earned a helper from dozens of clothes, and we took two more self-made gads from a neighbor. You can earn a hack yourself, it will be better, easier and more convenient, buying a Chinese hack will bend. It’s a pity I didn’t lose the photos of the self-made gachki.
When reinforcing, it is necessary to remember the main points of SNiP for reinforcing the foundation: 1) The dry ball of concrete must be at least 5 cm thick. This means that the reinforcement must not fit against the walls of the trench. On the sides of the trench, the reinforcement must extend 5 cm from the edge of the foundation. Below - 7 cm for the presence of a concrete pad and not less than 3.5 cm for the presence of such. 2) When the height of the MZLF is more than 70 cm, it is necessary to lay not only the bottom and top rows of the late reinforcement, but also the middle rows of the late reinforcement, as they do not carry weight, not the working rows of the late reinforcement , but also constructive. The middle rows of late reinforcement should be reinforced with reinforcement d=12 mm, if the wall is more than 3 m at the bottom or along the side faces of the foundation. That is, for the middle rows of the late building, 2 rods with 12 reinforcements are sufficient. 3) To anchor the reinforcement in the base wall that is adjacent, bending is required at the ends, or since the length of the rod (standard 11.7 m) does not allow bending, it is short, then you can use additional L-like coils for strong anchorage. 10-bend very easily, 12-bend with one hand, 16-bend for 3-4 seconds with 2 hands with both hands upright. The amount of reinforcement for anchoring is equal to 40 diameters of reinforcement, such as concrete for the foundation, grade M250 (the same grade of concrete, at a minimum, requires foundation fencing). That is, for example, for the reinforcement d = 16 mm, the dove of the reinforcement for anchoring = 16 * 40 = 64 cm. These numbers require the dove of the reinforcement, which is already anchored on the rose. At least 45 cm, then 64 - 45 = 19 cm. Meni required bending 16 on the corners at least 19 cm according to the rules.
Reinforcement: ten, ten, sixteen in total with delivery for 36,000 rubles, dozens more were lost for the foundation for the garage in the future. Roku.

7. Formwork for the plinth On the forum, it is advisable to install formwork from 40-50 mm thick planks. Fakhivtsi are happy to make such boards for everyone: for those who install formwork for the entire height of the foundation of 1.5-2 meters, and for those who, like me, install formwork only for the base, and for the above-ground part of the foundation. I understand that they are influenced by everyday norms and the foundation of such may not be harmed. Moreover, if it is recommended to use small-grade planks for above-ground formwork, there may be self-made ones that do not bother to install the formwork from 25mm 1.5 meter curled planks. If dad is on Mr. When the market put the 35-piece on the formwork, everyone laughed. Having said that, everyone take 25 and that’s it. They took the 25 and didn’t damage it every time. Nowhere did the formwork go belly. The heads are often placed with supporting trikulets and crossbars, our stinks stood every 1 meter. The height of the formwork should be 5 cm (as a minimum) higher than the edge of the foundation, so that the concrete does not splash.

For formwork, boards 25 mm thick, 15 cm wide. For three-pieces, bars 5x5 cm, boards 25 mm thick, 10 cm wide. For cross-sections, you can use bars, even if the roads are stinking, we cut cross-sections for any kind of mix. At the old Radian doors there are wonderful clear bars for this purpose. You can use the doors on the doors that are installed in new apartments for cleaning, people who live near the new apartment, then they simply fall out of sight. Well, it’s impossible to sell them. Note: During the winter, you can collect so much goodness and you won’t have to wash the sun-dried bars, which is good for trikutniks. These are even smaller and thicker than freshly purchased gray bars.
It is easier to install the formwork behind the vertical level. It is necessary to install the formwork boards so that the inner edge of the board avoids the outer edges of the Pinoplex sheets in the ground. That is, before formwork, Pinoplex sheets are installed in the middle to create one even, smooth wall with the bottom row of Pinoplex.
The bulo wood was purchased for about 10 thousand. rub.

8. We install the top row of Pinoplex in the middle of the formwork, screwing it in with screws up to 7 cm from the formwork. Screw the bells in, then screw them in again. It is better to make sure that the system is aligned, for example, the lower screw under the upper one, so that later, when the formwork is covered with earth, it will not be easy to find these screws. If the base is less than 60 cm and is still on the plot, like ours, then the bottom of the top row of EPS can be driven into the ground with flowers, only carefully and as the top of the trench allows (by digging by hand) J

9. Installation of liners in the trench for future sewer and water pipes. We bought a plastic ore pipe with a diameter of 200 mm and 1 meter for 650 rubles. 2 sleeves were cut out of it, where the sewer passes through. As the sewerage system passes through, having been excavated from behind, under what kind of structure the pipes will go and what adapters will be installed, visualizing the entire sewerage system in the mind, thinking about how the sewerage system will flow through the rooms and rooms. We go to the septic tank on the street and remove the clay and place the sleeves in place. You can find a lot of information on the topic on the forum.

Basic rules for installing channels that you need during installation:A) The liners are wider, the lower tubes of the channels are 2 times larger.

B) Pipes from the kitchen, shower, bath, d=50 mm, should be placed with a gap of no more than 3 cm per 1 meter of pipe.
V) Place pipes from the toilet and pipe exit to the septic tank d=110 mm with a gap of no more than 2 cm per 1 meter of pipe.
G) All transitions from horizontal to vertical should be done in small circles of 2x45 degrees or 3x30 degrees.
D) The remaining sewer pipe that goes to the septic tank must be straight.

In accordance with these rules and pipe installations for your project, remove the depth and place the sleeves. I bought a crossbar, rolls of 45 degrees each, having collected the entire structure in order to find out how deep it is after the connection with a vertical riser from the other one on top and below the pipe. The sleeves are fastened with dozens of pieces of reinforcement rods, showing the sleeves in your video.

For water pipes, lay them below the freezing depth. Since the official freezing depth in my republic is 1.6 m, then it is necessary to lay the pipe at a depth of 1.8 m (as a minimum). The sauce was buried at a depth of more than 1 m, trusting the “fakhivtsy” from the firm “Bidolakha”. Torik repairs frozen pipes when he has become a huge sum + hemorrhoids + every hour alive in winter without water.
The water pipe will enter the booth above the foundation from the boiler room that adjoins the booth, so I did not put a sleeve for it.
Concrete of grade M250, 48 cubic meters was poured on Wednesday, June 27, 2013. Until this hour, the planks have razed the ground into so many trenches that we carry heavy loads in our galoshes and boots, working hard. We could have forgotten about the concrete mixers that will reach our trench. I had a chance to install a concrete pump. Well, this is our special mercy, you have good information from someone else’s knowledge, so I think the money spent on a concrete pump can not be recovered as a waste of money. Koshtuvalo is satisfied with 3000 rubles. in a year. The owner began to sing, saying that in 6 years he had not seen anything less. I want the power of the car to be 120 cubic meters per year. J Rozumiya, everyone has their own business. A car like this costs 14 million rubles.

What can you do to help us hire a concrete pump?A) Talk to the concrete postal manager about uninterrupted delivery of concrete. Not just - “So, so, of course, everything will be in the best possible way,” but a written agreement, it is stated that during downtime, for example, more than in the 30th century, a certain amount is reached from the postal owner. penalty. My cleaning of mixers with concrete cost less than 3000 rubles. for a year J Water of a concrete pump saying that you can fill my foundation in 1.5 years, but this is already a business. Before that, you need to keep the car for at least 4 years.

B) Buy for all jams that will rotate the handle from the pipe of the concrete pump that supplies: dry eyepieces (can be found in a set of hammer drills, drills), cheap disposable surgical dressings, gum gloves. The pressure on the concrete is so strong that the breezes of the concrete fly into the eyes, mouth, hands dry under the concrete, and the nails on the hands hurt.
V) Place the concrete pump backwards to the mixers until they are moving.

But it’s really easy to fill in with such technology. There is no need to shovel the concrete; pour it evenly right up to the top of the base. It’s better to get the water back, so that you can immediately move the pipe where you want it to go. The same problem of all self-awakeners who fall to the ground, “the trench will collapse no matter what.” Before speaking, the work of jamshuts is also not cheap. And they need at least 5-6 individuals, so that the work works great. The hour allotted for cleaning the mixer is 40 hours. The time has come for the mixer to be idle while you work, costing 1200 rubles.

1 m3 of M250 concrete was crushed for 3,600 rubles. (3450 per 1 m3 + 150 for anti-freeze additives) The cold weather arrived and we decided to play it safe by soaking the anti-freeze additive into the concrete. Delivery of one mixer measuring 6m3 costs 2500 rubles. RUB 196,400 was spent on concrete delivered by 6-cubic mixers (8 machines). Brave 49 cubic meters, as we started on the forum, so that your volume calculations + 1 m3 in reserve. The result is exactly 48 cubic meters of pouring, and the excess was poured in front of the booth - a platform for the entry of a car J

The main thing is that there will be food for the development of this type of stitch foundation, not covered in this article and the information posted on those forums, and also not revealed in Andriy Dachnik’s book “MZLF”, write - I’ll try to be honest J

So I'll continue. For formwork I used polystyrene polystyrene from TechnoNIKOL. At the bottom of the formwork there is expanded polystyrene Solid 500, at the bottom edge there is Eco. As screeds for expanded polystyrene slabs, screeds from the company svt were produced. Sufficiently thought out ties that connect the edges of polystyrene foam.

I purchased a lot of expanded polystyrene from the SketchUp program. A number of screeds were insured from the company that sells them, but by the time about 40 of them were lost to non-victorists.

The assembly of the ties itself was, in principle, satisfactory to me, except that it was necessary to use sufficiently strong force to insert the reinforcement into the buried area. For those who want to use these screeds, I’m happy to tell you that horizontal reinforcement 12 requires double insertion. It’s a shame to use screws for knitting reinforcement (I don’t remember what the stinks are called) - stretch the jaws of the grippers and press the reinforcement to the seam. In this case, the process is smooth and not very tiring.

The svt shop screeds themselves serve not only for strengthening the reinforcement frame, but also for strengthening the concrete during pouring (more on this a little later).

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.

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 jointed EPS is not exposed to high temperatures and drying time, 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:

• 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. It is necessary to stack the cubes one on top of another in two rows with a small gap between them, and then pour cement at this gap.

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.

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.

As far as I understand, we are talking about the stitch foundation. If so, then it is possible to vikorize the eps in the frame of an invisible formwork. To the extent that it will be completely and clearly visible from an economical point of view, it will be different nutrition. Even for pouring a strip foundation, formwork is required from two sides for the entire depth of the foundation, and it is not at all difficult to insulate the foundation for the entire depth of the foundation. So, for example, if there is no plan for a basement in the cabin, then the foundation must be sufficiently insulated from the outer side to a depth of 50 cm according to the standards. u.

From the looks of handiness. In fact, it is said that laying the eps as an invisible formwork will significantly reduce the number of tasks associated with the installation and subsequent removal of the formwork, but not much. So, since formwork will still be needed, it will just be needed less.

Naturally, it is possible to lay the EPS from all sides of the foundation and to the entire depth, completely replacing the formwork, but there is no structural need for it, and behind the stained glass - it is more expensive to lay the lower boards for the formwork and glue for the EPS.

Forming a reinforced concrete foundation is impossible without hardening the formwork. It itself compresses the matured concrete mixture into a given shape until the hardening process is completely completed. Moreover, how clear the foundation will be to lay the longevity of life. The basis takes on the essence of the essence. The formwork will be made from various materials: wooden panels, metal profile sheets, moisture-resistant plywood, sheet metal. There are two types involved. Maybe be cold. In this case, it is immediately dismantled after the poured concrete has hardened. An unknown option conveys, for example, the operation that such a formwork structure had.

Expanded polystyrene flexible formwork: overall assessment

The list of materials for permanent formwork includes expanded polystyrene: gas-filled styrene (similar to polystyrene). As a different type, polystyrene is cured and extruded. This type of formwork further enhances the role of thermal insulation for the foundation. A light form for the foundation is considered to be the cheapest, cheapest and simplest. Regardless of the disposability of the history (blocks or sheets are lost in the foundation), it becomes one of the most popular memory books. The material is breathable, enhancing the thermal insulation power of the structure. The dimensions of the formwork depend on the dimensions of the expanded polystyrene slabs and blocks. If the leaves are cured, the leaves are cut well, but it is necessary according to the width of the leaf, and not across it.

Respect! The formwork is invisible - this structure is prefabricated. These parts are prepared strictly according to the technology of the manufacturing minds and to the necessary standards. To provide strength and rigidity, reinforcement is installed at the mounting groove.

What kind of power does polystyrene foam carry?

You can see a number of moments when laying the foundation from a small formwork made of expanded polystyrene, which is required from the forgotten people.

• Regardless of the fact that expanded polystyrene is classified as a plastic and is considered a synthetic material, it is also environmentally friendly, absolutely safe in the current environment. I don’t see any problems with the operation process. When burning, the same gas-like products are created as when burning wood.
• Inexpensive materials have linear prices.
• Characterized by acridity, buildup to self-extinguishing.
• The foundation formwork does not need to be additionally insulated, because the material has practically daily “cold areas”
• No laborious earthworks are required: it is enough to dig a ditch with a depth of 0.4 m. Well, the depth is not responsible for the greater depth of freezing of the soil.
• Prefabricated forms do not fall apart from falls and withstand wind and snow conditions.
• Expanded polystyrene blocks or sheets do not contain chemical reagents found in wastewater, cement components.
• Preparing the foundation for such formwork is the simplest, as it does not involve any difficulties.
• Easy installation.
• Rich in functionality: protection from cold and bacteria, noise reduction.
• Problem-free installation of communication systems through polystyrene blocks: they have special openings for this purpose.
• Capacity is built on the foundation of any configuration without obtaining additional human power.
• Durability: close to 80 years.
• Reduced labor costs (along with this important option): such formwork does not need to be dismantled after the concrete has hardened.

Respect! The trace is surrounded by the infusion of ultraviolet radiation on the polystyrene foam structure. In other cases, their thickness changes and their crispness increases. Organic agents (acetone, alcohol agent), as well as extinguishing agents, alcohol, and resins, have a negative impact on the exploitation power of the material. It is necessary to take care during waking hours and avoid contact that would endanger the formwork.

There are other restrictions:

• Polystyrene structures are not installed in the lower regions, where the soil freezes heavily, and the average temperature near the soil hovers below 0 degrees;
• Do not twist thin sheets of expanded polystyrene.

Yak vlashtovan formwork

The formwork for the foundation is made from slabs or blocks. One slab weighs approximately 1.5 kg with dimensions (mm): 1200x1200x250. Internal thickness 150 mm. Special grooves along the perimeter are required for fixation on the foundation, and grooves on the inside of the slab improve its adhesion to the concrete mixture during pouring. The structural elements are connected to each other using special jumpers. Let’s say “groove-ridge”. When filling the formwork with concrete, the track should be gradually strengthened so that there is no loss of exposed empty parts. The contact between the blocks is strong, so that the concrete warehouse will not leak through the bridges and grooves. The formwork walls are subject to pressure, so that they are fixed and not deformed.

When the base is being reinforced, the reinforcement must be laid at this stage. As a reinforcing material, as a rule, rods (vertical, horizontal) of different diameters are assembled in a layer depending on the type of material it is in: the main material or the binding material. Stable polystyrene blocks do not require additional struts and elements that support and visualize the given geometric shape of the base. Add more to dry the form.

Independent work for finishing formwork from polystyrene sheets

• Material is purchased at the latest cost. In this case, force majeure is required. Focus more on popular polystyrene polystyrene manufacturers.
• During cleaning, after desalination and removal of soil, apply the soil according to the plan, laying out the foundation. Dimensions of the guilty ones will definitely be completed. Particularly respectful to the locals is the growth of culture. They are molded with additional help.
• A trench is dug beyond the designated dimensions. It is necessary to create a small margin of width. The fall is 0.4 m with a depth of 0.5 m. A trench is formed right behind the level, because it is necessary to maintain horizontality.
• A gravel ball (0.1-0.15 m) is poured onto the prepared bottom. Good morning. In this way, drainage is installed for the removal of groundwater and at the same time additional thermal insulation.
• At the sobbing drainage ball, reinforcing rods are inserted. The smell creates additional damage to the concrete foundation and the elements of the formwork itself.
• A thin ball of concrete is laid, a kind of base (or sole) for the foundation. The sole smoothes out unevenness, dents, and ensures an optimal horizontal level for erecting the formwork.
• After digging out the cracks on the reinforcement rods, blocks are tightened.
• Jumpers are fixed between them, which clamp the formwork fragments together.
• To form the cutouts for joining the blocks, special cutout parts are used.
• A concrete mix is ​​laid between the blocks. The reinforcement is passed through in several places so that the wind comes out. Then it gets worse. I need to catch you.
• After this, you can proceed to the processing of the outer ball of slabs or blocks.
• These are the main stages of concrete formwork made from expanded polystyrene, which is difficult to make with your own hands.
