Monolithic ceiling in a house made of wood concrete. Installation of wooden floors in a house made of aerated concrete blocks Which floor is suitable from monolithic wood concrete

Wooden I-beams are a modern high-tech material that has no analogues in terms of price and quality ratio with an estimated rafter length of more than 5 meters. This roof will last long years, without deforming or collapsing under the influence of natural factors. The InterCity company calculates and selects I-beams for the rafter system, we also give recommendations on installation and joint solutions for wooden I-beams own production made from high quality materials using special technology.

I-beam production technology

Wooden I-beams are made from OSB boards and planed timber chamber drying(Wood series), as well as LVL-timber glued using European technology (LVL series).

Advantages of a wooden I-beam:

durability;
ideal declared geometry;
use only dry chamber-drying material;
possibility of installing long spans ( maximum length is 12 m);
high accuracy and stability of geometry;
possibility of year-round use in construction;
Possibility of internal installation engineering communications;
convenient installation (5-10 times faster than for reinforced concrete monolith, hollow core slab and boards), with minimal costs labor and without the need for special equipment.

Floor beams (I-beams) do not crack or deform over time. GreenLum products are an excellent alternative to heavy and difficult-to-work metal and reinforced concrete coatings, the installation of which requires “wet” work, additional involvement of reinforcement workers, concrete workers, etc.

Applicable in:

basement floors of houses made of gas blocks, foam blocks, gas silicate, wood concrete, aerated concrete, foam concrete;
interfloor ceilings houses made of aerated concrete, foam blocks, gas silicate, wood concrete, aerated concrete, foam concrete;
attic floors houses made of aerated concrete, foam blocks, gas silicate, wood concrete, aerated concrete, foam concrete;

Send us drawings of your block house, you can even make it by hand. We will quickly draw the layout of I-beams, select the cross-section, calculate the quantity, and also guide you on the cost and time of production of the material. If necessary, we will calculate the cost of delivery. The ceiling in a house made of blocks must be no less strong and reliable than the walls, so we calculate the beams for a load of 400 kg/m2, which ensures structural rigidity according to SNiP.

We talk about the installation of monolithic floors in a house made of wood concrete.

A monolithic floor is a load-bearing structure that divides a building into floors. In fact, it is a floor, so it must meet the requirements for strength and rigidity, and withstand its own weight and the weight of everything that is on it. The ceiling must also have the necessary heat and sound insulating properties and be fire resistant. The construction of a monolithic floor can be divided into stages:

1. Installation of formwork

The formwork consists of a deck and telescopic racks, securely fixed with tripods. The racks are installed at the same distance from each other, which is determined by the thickness of the slab: the thicker it is, the closer the racks are. Place on telescopic stands longitudinal beams, then perpendicular to them - transverse ones. We check the formwork structure for evenness using a level and a level. The quality of the surface of the future monolithic floor depends on this. Then we make the flooring with laminated plywood sheets 18 mm thick. It performs the function of a deck, which is one of the main structural elements of the formwork panel. The advantages of using laminated plywood include high moisture resistance - the sheets can withstand repeated pouring cycles without deformation, thanks to the laminated surface plywood sheet monolithic floors turn out smooth and even. We seal the joints between the plywood with film to prevent concrete from leaking into them during pouring.

2. Floor reinforcement

The reinforcement gives the structure rigidity, preventing the monolithic slab from breaking or bending. We install the reinforcement at a distance of 25-30 mm from the end to eliminate interaction between metal and air and prevent corrosion. Special plastic stops and clamps lift the reinforcement and create a protective layer of concrete underneath it. The size of this layer depends on the thickness of the floor, span length and other factors.

3. Filling concrete mixture

After reinforcement, we perform grouting using a concrete pump. To compact the concrete mixture, we must use an internal vibrator.

In the first days, concrete must be protected from precipitation and moisture loss, so when it rains, we cover it with a special film, in cold weather we warm it up and use it. antifreeze additives, in hot weather, on the contrary, we moisten it to prevent cracks.

4. Dismantling of formwork

Dismantling of formwork, final stage on installation monolithic slab, occurs 4 weeks after concreting.

One of promising directions is the use of wood concrete in combined load-bearing structures covering and floor slabs, since in existing projects they occupy an even larger share wooden structures(coverings and ceilings, roofing, vestibule, flights of stairs), which are short-lived and not fire-resistant. In our country and abroad, there is experience in residential and industrial construction using wood concrete in combined coatings as load-bearing slabs.

IN production association Dneproenergostroyindustry organized manufacturing for construction residential buildings load-bearing structures made of wood concrete in the form of volumetric block elements. The Oktyabrsky DSK of the USSR Ministry of Forestry produced three-layer arbolite slabs for covering and flooring, the top and bottom layers of which were made of heavy reinforced concrete.

Slabs measuring 360x120x18 cm were used for the construction of a three-story 8-apartment building for roofing and roofing according to an experimental project of Giprolesprom (Oktyabrsky village, Arkhangelsk region).

Arbolite structures in coatings and ceilings have small spans. Flexible load-bearing elements with a span of more than 4.8 m are not produced on a mass scale. This is due to insufficient knowledge of the use of wood concrete in bending elements and limited experience in their use. Due to the low strength properties of wood concrete, its use in bendable load-bearing elements of coatings and floors can be carried out mainly in the form combined designs composite section in combination with heavy concrete M100-300.

Abroad for coatings industrial buildings and residential buildings with a combined roof, durisol slabs reinforced with steel in the stretched zone are successfully used. Depending on the span and load, the slabs are made 10 and 12 cm thick, 350 cm long, reinforcement is carried out using reinforcement bars concreted with heavy concrete.

NIIZHB together with Soyuznauchplitprom have developed arbolite floor slabs for residential and public buildings Episode 115. The panel design is designed for spans of 3.6 and 4.8 m with a thickness of 18 cm. The panel has a layered section: the bottom layer is 3.5 cm thick, the top layer is 2.5 cm thick from M200 heavy concrete, the middle layer is 14.5 cm thick from wood concrete. M25 or M35. Working fittings, made of steel class A-II or A-III, are laid in the form welded mesh(from rods with a diameter of 10-12 mm). In the bottom layer of the panel, the middle layer of wood concrete M25 and M35 with an average density of 700-800 kg/m 3 performs heat-insulating and sound-proofing functions. The weight of 1 m2 of such wood concrete panel is 253 kg. The economic effect of using wood concrete floor panels is as follows: the cost of floor material compared to the cost of industrial wood is reduced by half; labor intensity of work on construction site decreases by 30-40%, the durability and fire resistance of floor structures increases.

Based on the results of the research, a “Guide for the design and manufacture of wood concrete products” was developed, which provides a method for calculating wood concrete elements and provides the standard and design characteristics of wood concrete. However, their scope of application is limited. They cannot meet the needs of industrial and agricultural construction, where the most effective is the use of 6 m long covering slabs. The production and use of slabs for a span of 6 m would allow for complete unification of load-bearing and enclosing structures.

The design group of the Perm Regional Potrebsoyuz developed working drawings “Large-panel arbolite slabs for covering KAP” measuring 1.5x6.0 m. Constructive decisions large-sized arbolite covering slabs with a span of 6 m were developed by engineer. Baidin with the participation of TsNIIEPselstroy.

Experience in the experimental construction of buildings in which wood concrete is used in coatings and floors as load-bearing elements with a span of 4 and 6 m is available in the Perm region. For example, in the villages of Verkhnie Gorodki a garage was built and two-storey house, in the village of Komarikhinskaya there is a bookstore. When examining the garage and other buildings after two years of operation, it was found that wood concrete slabs with a span of 4 and 6 m in a combined covering do not have excess deformations. Compared to reinforced concrete, such coatings have a number of advantages, in particular, they do not require thermal insulation.

As the Perm experience has shown, when insulating roofs mineral wool slabs 10 cm thick for every 100 m2, according to the standards, 23 man-days are required for laying insulation and 7.35 man-days for installing a vapor barrier, screed and bitumen primer. Total labor costs are 42.13 man-days. When using wood concrete roofing slabs that do not require insulation, labor costs for roof installation are reduced by more than 3.4 times. In roofless combined roofs made of arbolite slabs, immediately after laying them, sealing and leveling the surfaces of the seams, you can glue a waterproofing carpet or sew slate directly to the slabs. The introduction of arbolite load-bearing coatings into construction will reduce the weight of buildings, reduce material consumption, labor intensity of construction, and the cost of constructing objects.

The most creative method of constructing buildings, which allows you to get a structure of any shape and configuration, is construction monolithic walls, which do not have connecting seams, and therefore provide the greatest tightness. By modeling a casting mold with the desired profile, you can get any futuristic contours country house, by sequentially pouring and rearranging the formwork.

The main disadvantage of this method is its high cost and labor intensity, since sand-cement screed heavy and expensive material. Alternative way budget construction of a building using a similar technology is the construction of house walls from monolithic wood concrete, which is much lighter, which means the work can be done with your own hands.

Preparation of wood concrete mixture

The term arbolite combines a wide range of mixtures of crushed plant fibers with cement, making it possible to obtain a lightweight building material consisting of 80–90% shavings or crushed particles various plants. The composition of such a construction material makes it possible to minimize the cost of its production, since crushed plant fibers can be obtained from any waste from the wood processing industry intended for disposal.

The recipe for mixing the components for the preparation of wood concrete will depend on the class and brand of material that should be obtained in the end, based on the purpose:

for external walls you need the most dense and durable mixture composition;
internal walls and floors may have lower density, but higher thermal and sound insulation.

Table of mixture composition (cement/filler/water) for popular brands of wood concrete depending on the filler

Filler	Component content, kg/m 3
Filler	B0.35(M5)	B0.75(M10)	B1.0(M15)	B2.0(M20)	B2.5(M25)

When accepting the composition of the mixture presented in the table, a number of assumptions should be taken into account and the data adjusted based on the actual parameters of the components:

The proportion is given for cement grade M400, that is, when using other grades, the coefficient of change in strength should be entered: M300 - 1.05; M500 - 0.96; M600 - 0.93.
The filler consumption is given for absolutely dry material, which is rare for real construction conditions; therefore, its mass should be increased by multiplying by a factor greater than one by the proportion of water in the filler composition (moisture content in % divided by 100%).
Quantity clean water should be reduced by the amount of its content in the composition of the chemical additive, which is injected as part of a mixture of a certain concentration.

Types of formwork and their construction

For the construction of any monolith of walls and floors, formwork is required, which is a structure of various material designs that limits the space filled with liquid mortar, which, after hardening, forms the structural elements of a house or other building. Depending on the geometric shapes, which are planned to be reproduced in the architecture of the house, for example, concave or convex walls, may require special forms made in a factory. Although in most cases, the construction of walls from monolithic wood concrete involves straight lines and shapes that can be reproduced using wooden formwork, assembled with your own hands from boards and bars.

Considering the hygroscopicity of wood concrete, a reasonable decision would be permanent formwork from polystyrene foam boards, creating a double-sided vapor- and heat-proof layer. The assembly of an enclosing form made of polystyrene foam consists of connecting standard elements using special locks that are molded during the manufacture of formwork elements and are an integral part of them. A device of such a design will require additional costs, since a non-removable polystyrene foam structure cannot be made with your own hands from scrap materials.

Having chosen wood concrete as a structural material for a house to fill the monolithic walls and floor of the house, the use of factory molded products or permanent formwork will be illogical. It would be more reasonable to make panels from boards or chipboards, by connecting them together and setting a distance equal to the thickness of the walls, you can get a reusable device that can be rearranged in horizontal and vertical planes.

The surface of the boards facing inward must be well processed, since all unevenness and defects in the wood will be transferred to the walls, which means an additional finishing layer will be required to eliminate them. So that after the wood concrete hardens in the form, the limiting structure can be easily dismantled, the surface of the boards or chipboard should be pre-treated using any oily composition, for example, used motor oil.

Monolithic construction technology

Arbolite is the lightest structural material, therefore, for the construction of walls, a monolithic floor made of reinforced concrete is not required; it will be enough to limit yourself to a strip foundation made by yourself, the width of which should be equal to the thickness of the walls. As a material for the device supporting structure reinforced concrete or brick should be used at home, capable of supporting the weight of a building of three floors, since a large number of floors for monolithic structures from wood concrete is not allowed. Subsequently between strip foundations it is necessary to install floors, which can also be made of wood concrete.

Monolithic construction can be carried out in several ways:

continuous floor-by-floor pouring, in which permanent formwork is installed on the floor or foundation, and the mixture is supplied from an automixer or a local concrete-mortar unit;
by pouring belts, when formwork of a certain width is formed immediately along the entire perimeter of the building and sequentially moves from bottom to top;
segmental pouring, when a section of a wall of a fixed height and length is poured in one go, with restrictions on the sides.

Formwork for monolithic floors and arbolite floors Manual tamping ceilings of the first floor Compacted floor and prepared formwork for pouring walls Rearranged formwork for pouring the next layer of wood concrete Rearrangement of formwork Poured and compacted wood concrete in formwork for walls Formwork for the façade side Walls made of monolithic wood concrete

If building a house is done with your own hands, then the first two options are frankly utopian, but the last one is the most realistic and practically feasible, even in the absence of a concrete mixer.

The sequence of operations in this case will be as follows:

The formwork prepared with your own hands is placed on a certain section of the foundation, into which reinforcing rods must be walled up in advance, reaching the height of the mark where the floor of the next floor will be. The diameter and pitch of the rods when installing wall reinforcement is selected based on the planned number of storeys of the building; the higher it is, the shorter the distance and the greater the thickness of the embedded parts.
The lower edge of the fencing panels overlaps with the foundation of the house, and the upper cut is fixed in two or three points according to the thickness of the wall. For a tight fit, the panels are pulled together with metal pins with a diameter of 3–5 mm, which, after removing the formwork, must be cut flush so that there are no holes left in the wall. The gaps on the sides of the formwork are closed with pieces of boards.
Wood concrete is poured into the prepared segment, the composition of which is determined by whether it is an external wall or partition, adding 3–5 cm to the top edge of the formwork. After pouring, it is imperative to compact the solution by manually compacting it with a specially prepared pin along the entire length of the pour, thereby removing air bubbles from the wood concrete layer in order to achieve the desired density and strength.
After the wall section has hardened, the formwork can be removed, protected, oiled and installed on the next segment, after which all previous manipulations must be repeated. The rearrangement is carried out sequentially: first in one plane in height, and after closing the perimeter, the rise is made to a higher level.
After reaching the mark of the next floor, you must install the floor by filling it with your own hands with wood concrete on top of specially prepared formwork or by laying standard reinforced concrete slabs ceilings After the floor is equipped, all operations are repeated until the design height of the building is reached.

New, and in in this case, forgotten old, wood concrete returns to the market building materials. As practice has shown, building a house from wood concrete blocks with your own hands is a good prospect for building a strong, warm and reliable private house.

Disadvantages of brick and concrete walls known to everyone wooden houses Not everyone can afford it. An alternative to the above is wood concrete. Having 80-90% wood chips, connected with a cement binder and modified with chemical additives, wood concrete eliminates the shortcomings and enhances the advantages of wood and concrete.

Wood concrete was created and tested in the middle of the last century, and its production is regulated by GOST 19222-84.

Technologies for the construction of private houses from wood concrete

A house can be built in two ways:

Construction from arbolite blocks. In this case, industrially manufactured ready-made blocks from wood concrete;

Often the decision is made to make wood concrete with your own hands. Before starting work, it is important to make sure that the blocks have gained the strength and hardness necessary for work.

Monolithic construction from wood concrete. The use of this technology involves the formation of permanent formwork and subsequent pouring of wood concrete mortar into it.

To build a house from monolithic wood concrete, you need to study the technology of constructing monolithic walls. The remaining stages will be identical to block construction.

In this article we will focus on detailed description first option.

How to build a house from wood concrete blocks with your own hands

The main stages of work in the form of successive steps from A to Z.

Stage 1. Design of houses made of wood concrete

The development of the project precedes the start of work due to the need for its coordination and approval by the licensing authorities. In addition to the house plan itself, the cottage project contains information about the materials used, places and methods of connecting to communications, electrical and gas supplies, type of foundation, etc. The project makes it possible to further calculate the amount of material and the load it creates.

For your information, the design of a house made of wood concrete is no different from the design of a house made of foam concrete, and therefore a typical project can be used, taking into account the absence of the reinforcing belts necessary for foam blocks.

Stage 2. Selection of material for construction

Before you start construction work, you need to make sure you choose the right wall material.

Arbolite certainly has a number of advantages. But! Only if it is of high quality and is used for its intended purpose.

You should know that wood concrete is used in the construction of buildings with a height not exceeding 7 meters. (height self-supporting wall). This makes it attractive when constructing a 2-3-story private house or cottage with an attic. In combination with columns or other structural elements (support pillars), taking on part of the load, construction of more floors is allowed.

Which wood concrete is suitable for building a house

To purchase a high-quality block, professionals advise paying attention to the determining factors:

price. Homemade wood concrete is much cheaper;

fullness and uniformity of the block. The chips should be of more or less the same fraction, densely packed. The looseness of the block indicates its low compressive and bending strength;

Note: the use of sawdust increases the thermal conductivity of the block. Large chips are not completely saturated. As a result, the adhesion of wood to cement is disrupted and the block loses strength.

block geometry. GOST allows a deviation from the specified size not exceeding 5-7 mm. The use of a special weight during the manufacturing process allows us to reduce deviations to zero.

Note: the unevenness of the blocks can increase the consumption of masonry mortar by 40%, makes the use of special adhesive mixtures inappropriate, and increases the consumption of plaster when finishing, increases the complexity and duration of work.

color and impurities. Insertion of impurities or differences in color within the block indicate a violation of the manufacturing and drying processes.

certificates that will indicate: cement quality, complete chemical composition, test results.

Stage 3. Construction of a foundation for a house made of wood concrete

A distinctive feature of wood concrete is its good bending strength, regardless of the purpose of the block. This gives the block the ability to recover from stress. In practice, this removes restrictions when choosing the type of foundation, which is an integral part of any structure. To a large extent, it is the quality of the foundation that determines the lifespan of the house.

What is the best foundation for a house made of wood concrete?

In practice, any can be used. Most often it is tape or combined.

Foundation technology for an arbolite house:

marking for the foundation;
removing the soil layer to the required depth;
arrangement of sand and crushed stone cushion;
compaction (recommended with watering to achieve greater density);
installation of formwork;
reinforcement;
pouring the foundation.
waterproofing the foundation strip;
backfilling of sand inside the squares formed by the foundation strip followed by compaction;
complete waterproofing of the foundation.

Note: during the pouring process, the channels provided for by the project are left for further installation of communications.

Before starting work, you need to decide on the size of the foundation.

depth of placement. Depends on the type of soil, distance to groundwater, number of storeys of the building. The dependence of the parameters on the type of soil is shown in the table;

foundation thickness. Depends on the total (static and dynamic) load on it.

When calculating static loads, you need to take into account:

materials used in construction (their weight and quantity);
presence of a base;
wall material;
material and number of floors;
roofing material used;
presence of insulation and its type;
number of windows and doors. Total weight of elements warm circuit. When calculating the weight of the doors, you need to remember that entrance doors usually made of metal, which affects the load they create;
material for facade cladding;
materials for interior decoration;
floor covering and type of flooring.
calculated weight of furniture (195 kg/sq.m. according to SNiP 2.01.07-85).

In addition, dynamic load is taken into account:

snow load in the region (see map). For example: the annual snow load for Moscow is 180 kg/sq.m. (according to SNiP 2.01.07-85). By multiplying this number by the roof area we get the total load. The calculations take into account the roof configuration and the resulting result must be multiplied by the coefficient M (0.94).

wind load is calculated by the formula = House area * (15 x House height + 40);

soil resistance to pressure exerted on it (according to SNiP 2.02.01-83). According to this standard, the resistance must exceed the pressure on it by 30%. The pressure of a building is calculated by dividing the weight of the building by the area of the foundation (sole).

Note: if the soil type is not determined, the minimum resistance value is used for calculations.

Stage 4. Construction of the basement of a house made of wood concrete

The plinth will better protect the wood concrete block from the influence of water. The recommended plinth height is 500-600 mm (depending on the level of precipitation in the region and the availability drainage system around the house). The base is made of brick or concrete.

Stage 5. Construction of walls from wood concrete

Let us immediately note that the construction of arbolite walls is notable for the fact that it is advisable to use cement-sand mortar. The choice is due to the uneven geometry of the block, which makes it economically unprofitable to use special adhesive solutions used for masonry cellular concrete such as Ceresit CT 21. Increased consumption glue mixture will increase the budget for building a house.

Consumption cement-sand mortar 1 m3 per 8-10 m3 of wood concrete blocks. The value is approximate, because the geometry of the blocks is not constant, the discrepancy can be from 5 mm to 1.5 cm in width and height.

What to place wood concrete blocks on?

An alternative to the classic solution can be:

Perlite mortar for laying wood concrete. Its feature is the ability to increase the thermal insulation of masonry. How to make perlite mortar: perlite is added to the classic mortar (cement, sand, water). The ratio is 1 part cement = 3 parts perlite.

Note. Perlite is volatile, which means you need to work with it in the absence of wind.

Sawdust concrete mortar. Recipe: 3 parts of sawdust are filled with a solution of aluminum sulfate (15-25.00 rubles/kg) or calcium chloride (28-30 rubles/kg). When stirring, the sugars contained in the sawdust are neutralized. Then 1 part of cement is added.

Good reviews has thermal insulation masonry mortar with perlite LM 21-P. The Quick-mix mixture has water-retaining ability, so the blocks do not need to be moistened separately. Supplied in 17.5 kg bags, in the form of a dry powder. The solution is easily mixed with water (stir for at least 5 minutes) by hand or with a mixer (mixer). Ready solution use within 1-2 hours.

Laying walls from arbolite blocks

The technology for laying wood concrete is identical to brick or foam concrete wall, in addition, wood concrete strongly absorbs moisture from the solution, which means that the blocks need to be moistened before starting work.

1. Laying the first row of arbolite blocks

The masonry starts from the corner and is laid out in rows, periodically checking the degree of deviation with a level. The blocks are easy to process, so there will be no difficulties with adjusting the size.

The width of the seam depends on the geometry of the block and is 10-30 mm.

The solution is applied to the block of the previous row along the edges of the block. Thus, an air thermal break is obtained, which compensates for the high thermal conductivity of the masonry mortar.

On the construction forum, according to reviews, many users use additional method insulation of masonry by laying polystyrene foam tape in the seams, wooden slats etc. The gasket creates a gap in the mortar joint and thereby eliminates the appearance of cold bridges. How expedient this is, everyone decides for themselves.

Material prepared for the website www.site

The optimal thickness of wood concrete walls is 30 cm, for houses of two floors and above - 40 cm. A simple rule applies - the thicker the wall, the warmer it is. A wood concrete wall thickness of 20 cm is possible if cladding with brick or additional insulation inside and out. How thick the wall should be depends on what region the house is in, how it will be heated, and what the construction budget is.

2. Reinforcement of walls made of wood concrete

Craftsmen advise stiffening a wood concrete wall by reinforcing it. To reinforce wood concrete, polymer (plastic) mesh or metal rods treated with anti-corrosion compounds (for example, UR-108 enamel) are used. Thus, the corners of the building, the junction of walls, window and door openings are strengthened. Unlike aerated concrete and foam concrete, there is no mandatory requirement for masonry reinforcement, but many users reinforce every 3-4 rows of masonry.

3. Laying wood concrete (dressing)

Arbolite blocks are laid in a checkerboard pattern (laying with dressing). This is necessary for reliable adhesion. No more than 3 rows are laid out around the perimeter. Then there is a break for a day. During this time, the solution will dry and you can continue working. That's why it's often external walls are erected together with internal ones.

Advice. Adding additives to the solution that increase the rate of strength gain of cement will increase the speed of work.

The “Shuttle” accelerator, which provides strength gain in 12 hours (consumption of 3 liters per 100 kg of cement, price 75 rubles/100 g) and the “Virtuoso Start” accelerator, which also contains an anti-shrinkage agent, have proven themselves well. Provides 50% strength gain in 3 hours (consumption 1 liter per 100 kg of cement, price 80 rubles/100 g).

4. Lintels over window and door openings

The photo shows step by step how to make a lintel over a window and over a door in a house made of wood concrete. Two options for covering openings.

Installation of jumpers from a metal corner

(the edges of the corner are walled into the walls, blocks are installed inside)

Installation of a channel lintel

(V arbolite blocks cut a groove for inserting a channel)

5. Installation of an armored belt under the ceiling in a house made of wood concrete

After erecting the wall, before laying the floor (interfloor or attic) on the wood concrete wall, you need to pour a concrete (monolithic) reinforcing belt. Its arrangement will give the wall strength, allow it to more evenly distribute the load and securely secure the Mauerlat.

How to make an armored belt on wood concrete:

one outer row is laid out in half a block (you can purchase a narrow block or cut a wall one). This will be the outer part of the formwork;

With inside formwork is installed from edged boards, plywood or a narrow wood concrete block is also used;

processed reinforcement is placed into the resulting recess (diameter 10 mm, in 6 rows) and filled with concrete (the grade of concrete is the same as that used for the foundation).

To make an armored belt, it is convenient to use a special U-shaped block (tray U-arboblock).

6. Installation of house floors made of wood concrete

A monolithic reinforced concrete slab, wooden or metal beams can be used as a flooring material.

Advice. Manufacturers of wood concrete blocks recommend producing. To do this, it is not necessary to pour a concrete belt. After all, the ability of wood concrete to “pull” moisture from concrete is not in the best possible way affects the quality of the fill. Additional supplements will be required. It is also advisable to use wooden floors for the installation of door and window openings. The masters completely agree with them and recommend using wooden beam as a lining of the perimeter of the wall under the ceiling.

The Mauerlat is attached to the wood concrete with the obligatory laying of a layer of waterproofing.

7. Installation of communications in a house made of wood concrete

Laying communication systems does not create difficulties. Any holes can be easily made in wood concrete blocks, so there is no need to immediately lay additional channels for sewerage, pipes, heating, etc.

Some people use a hollow block, installing it on an edge.

Stage 6. Construction of a roof for a house made of wood concrete

Can be installed on arbolite walls rafter system any configuration. Choice roofing material also not regulated.

Experts advise using bitumen shingles for roofing works. They explain their choice by saying that bitumen shingles can perceive minor vibrations of wood concrete walls without the appearance of significant defects.

An important nuance when constructing a roof will be compliance with the rule - moving the roof 300-500 away from the wall, which will protect it from direct contact with rain and melt water.
