Proper, competent installation of overlaps is a guarantee of a reliable, long-term service life of buildings. For buildings made from blocks (aerated concrete), an additional support is necessary - reinforcement. Aropoyas in a house of aerated concrete is a special additional structure, mandatory when installing beams of overlaps, roofs. Production of reinforced belts, for houses from a cellular concrete, the installation of overlapping is regulated by SNiP. Here are the brands and characteristics of the beams, the necessary parameters of the wallpaper on the walls, from which and how is it. Compliance with these standards is directly related to the structural resistance of construction structures.
Aropoyas is a mandatory element when building a house
For what is necessary Armopoyas
The structure of aerated concrete material will not be able to withstand high loads (shrinkage of the building, ground precipitate under it, daily temperature differences, seasonal changes). As a result, the blocks are cracked, destroyed. To avoid various kinds of deformations, monolithic reinforced concrete fixtures are installed. The reinforced belt takes these loads on itself, distributes them evenly, ensuring the reliability of the structure, connects the walls into one.
It is also needed for the distribution of vertical load. Putting the structure of rigidity, it does not give the occurrence of the motion of the overlap (the aerated concrete blocks are expanding when moisture moves, steam). For this, he also received the name - unloading, seismopoyea. Another one of the destinations of armoances, protect the edges of the upper blocks from destruction (installation of inter-storey floors). Clean the point load of the beam wooden frames, when building a roof. Given these qualities, Armopoyas is required for beams, the slabs of overlapping the second (subsequent, roofs) of the floor in a house of aerated concrete blocks.
Armopois is needed for uniform load distribution for the foundation and wall
During the construction of one-story buildings, the question often arises, whether Armopoyas needs for a single-storey house of aerated concrete. This item is simply necessary if:
the support beams (Mauerlat) are installed, which are attached to the roof rafters, especially this is relevant for projects of single-storey houses with an attic;
the foundation is made on an unstable soil to bind the entire design to one (carrier) system.
The prerequisite for houses from aerated concrete blocks is a complete slottle of the belt. The design circuit must be without breaking. Refusing to use Armopoyasa, the appearance of cracks is inevitable. Even, despite the lightweight wooden overlaps and reinforcement of masonry from aerated concrete blocks.
Unlike brick structures, for the house of aerated concrete, the reinforcing belt must be made by a solid ring.
Sealing reinforced belt
This type of design is performed for slab or beam overlap. The main appointments of overlaps include perception and transfer of the load of their own weight, interior, people on the walls, dividing the inner space of buildings on floors, overlapping the spans. This is a supporting design, based on the external and inner walls around the perimeter.
The basis for the pouring of Armopoyas is the support surface of the bearing walls, which perceives the whole mass of the poorer. General requirements:
the installation is made on the entire perimeter of the future building, taking into account the inner walls;
for external bearing walls, blocks are used with a density of not lower than D-500;
height is made at a height of aerated concrete, or is allowed less (200-400 mm);
the width of the belt is 500 mm (it is possible to decrease by 100-150 mm);
the reinforcement frame falls on the stands (brick, pieces of blocks, plastic clamps) height 3 cm so that the walls do not touch the walls, thus, the so-called protective concrete layer is created;
for the fill, concrete is not lower than the B-15 brand.
Filling for pouring concrete solution with reinforcing grid
On our site you can find the contacts of construction companies that offer the maintenance service of the foundation. Directly to communicate with representatives, you can visiting the exhibition of houses "Low-rise country".
Aropoyas for aerated concrete under the beam overlap is poured into a pre-prepared formwork. This frame is made from:
-
Blocks of aerated concrete.
Plastic.
Aluminum.
This kind of formwork is used most often. This is the cheapest and in demand. By installing a double-sided removable wooden frame (spit from wood), it is fastened with self-drawing on both sides of the wall (to the blocks of aerated concrete). The upper part is tightened with wooden jumpers (step 800-1000mm). It is necessary that at the pouring concrete did not move the design.
Wood formwork is the most common option due to its availability
The reinforcement frame (the diameter of the reinforcement is 8-14 mm), made in the form of the "ladder" (jumper compound with increments of 5-7cm), is placed in the prepared space. The bars fit together using a knitted wire (every half meter), forming a square shape. It is not recommended to use welding, due to the rusting of the welding seams in the concrete. For the beam overlaps (with no high load), it is enough of a frame of two rods, with a monolith height - 30 cm. For overlapping with plates, armopyas with increased reliability (4 rods and monolith - 40 cm) is used.
After removing the formwork, the outer wall is insulating with Armopoyas. If when finished, the outer walls are only plastering, then to remove the "cold bridge", the formwork shifts the walls. And in the resulting niche, then the insulation is installed.
You can use a unilateral removable formwork. In this case, the outer function performs aerated concrete blocks (10 cm thick). They are placed on the lower row, with the help of glue. On the inside the wooden frame is mounted. After that, the insulation is stacked (5 cm) and fittings. The top is also tightened with jumpers.

Belt Using Blocks
The manufacture of such a formwork requires additional good blocks or ready-made U-shaped aerated concrete products. In this case, the internal (thickness 5 cm) and the outer (10 cm) or U-blocks (with walls - 5 and 10 cm) are installed on glue (from above. Armature and insulation (to the outer wall) are placed in the internal space. After, the fill of concrete occurs. For openings (doors, windows), at the top level of the previous row of masonry, wooden jumpers are installed. They are fixed with vertical backups.
This formwork is relatively easy and quickly mounted. But it is not very popular due to the need for a dozpecus of the material, and as a result - increasing the cost of construction.
Armopoyas with concrete blocks will be more expensive, but with their help the place of reinforcement will not be noticeable
Belt under Mauerlat
This armoomas is set to the bottom of the attic, both for single-storey and two or more floors. It is necessary for the installation of mounts under Mauerlat, and takes the main load from the rafter system (vertical, aimed at breaking the effort) and the burden of snow, wind. Installed mounts for timber simply in aerated concrete will not withstand these loads. They are separated (due to the low strength of the blocks) and Mauerlat will shift from its place, which will inevitably lead to negative consequences. Also, he fulfills the role of additional strengthening of the walls, without giving them cracking.
Such a belt can be made of reduced dimensions due to thickness (by calculating the load correctly) and use two reinforcement rods for the frame. A distinctive feature of such Aropoyaka serve vertical studs with nuts. They are installed with the reinforcement frame, before the fill with concrete. It is for these fasteners and will be installed Mauerlat, fixing on top of nuts. This is the poorer basis for the rafting roof system.
In the same way, you can make Armopoyas in a house of aerated concrete and under wooden floors. Pre-prepared fasteners for wooden structures will avoid subsequent drilling of concrete for installing anchors.
Pouring concrete
To fill the belt, after performing all the preparatory work, a ready-made concrete (M200) is used or is manufactured in place in the proportion of 3-5-1 of:
-
cement (M400).
Pouring is carried out not in parts, but completely throughout the perimeter. In case of the impossibility of such a process, the necessary jumpers are made in advance. Before filling the next batch of concrete, temporary jumpers are cleaned, the joints are wetted with water and poured concrete. The seal of the solution is made by iron pin, removing air bubbles from it. In the process of frozen (about 5 days), concrete is watering with water to increase strength.

Conclusion
The reinforced concrete monolithic belt made in all the necessary parameters and rules, give a house from aerated concrete blocks necessary strength and durability. It will protect the walls from premature cracks, allow you to make reliable roof.
In industrial and housing construction, various types of materials are used, including porous concrete. A popular variety of cellular concrete - aerated concrete, which has a complex of advantages. However, without a special gain, it is susceptible to cracking, which is associated with reduced strength. To solve the problem, armopoyas on aerated concrete is built. This design allows you to increase the stability of the bearing elements of the building to loads, as well as increase the strength of the structure. Consider the features of the strengthening belt, we will deal with technology.
What properties has aerated concrete
By preferring a gas-filled concrete, it is necessary to thoroughly analyze its properties and explore the specifications. Features of the material are associated with manufacturing technology. In the production of aerated concrete in the depths of the array, air pores are uniformly form. This feature of the distribution of air cavities has a positive effect on the thermal insulation properties of the material. Freewood walls do not require special thermal insulation and allow you to reduce the costs of maintaining a comfortable temperature.
The building erected from aerated concrete blocks is more often influenced by the natural elements.Advantages of use in the construction of the buildings of a gas-filled concrete appreciated professional builders.
The material is different:
- increased thermal insulation properties. They allow you to significantly reduce the overall level of room heating costs in winter;
- resistance in temperature differences. Building material is not cracking with deep freezing and further thawing;
- increased soundproofing coefficient. The cellular structure creates a reliable sound barrier;
- ecology. In the process of manufacture, an environmentally friendly raw material is applied that does not affect the health of others;
- good workability. No special tool and equipment for giving blocks necessary forms;
- reduced weight. Light walls from aerated concrete do not have an increased load on the base of the building built;
- resistant to the development of fungal colonies and mold. In the thickness of the aerated concrete and on its surface, pathogenic organisms are not formed.
The main minus porous building material is a minor reserve of safety, to increase which armooisas on aerated concrete is equipped. Problem zones are strengthened by the power frame, which is poured by a concrete mixture.
Armopoyas for protection is created on aerated concrete, smoothing the impact of climatic factors Features of the Armopoyas device for aerated concrete
In the lexicon of professional builders, the term "Armopoyas" is quite often used. Private developers do not always have an idea of \u200b\u200bhow Armopoyas is performed for aerated concrete and what it represents. This is a powerful design of a closed form, repeating the contour of the structure.
It is formed on the basis of available building materials:
- reinforcement lattice. The steel rods with a cross section of 0.8-1.2 cm are binding to knitting wire into a frame that increases the strength of concrete during deformation. Power construction includes longitudinally located rods of increased diameter. They form a spatial design when connected with square or rectangular jumpers located perpendicularly. It is not allowed to use welding, weakening the strength of the structure;
- concrete solution of the increased strength of the M350 brand and above. It is prepared on the basis of a rubbed-sand mixture and portland cement mixed in the standard ratio - 1: 3.5. The finished composition is filled with a formwork design, in which the reinforcement frame is rigidly installed. As a result of continuous fill and thorough tamping, a reinforced belt is formed. It prevents the destruction of the building and strengthens the design.
To ensure the required stock of strength, the Armopoya height should be observed. The design of the formwork allows the concrete belt to make the necessary form and ensure compliance with its size.
Aropoyas for aerated concrete not only increases the resistance of the walls of the house loads from the inner and external environment, but also has a connecting purpose For formwork apply:
- planed boards. They are knocked into the shield elements that are fixed with jumpers and wire;
- polystyrene plates. The properties of the material that generates non-separable formwork makes it possible to improve heat insulation;
- p-frame configuration gas concrete blocks. Using finished items can be significantly accessed by the formwork assembly.
Deciding on the design of the formwork, it is important to ensure tightness, as well as increased rigidity. This will create a durable armopoyash under the beams of overlapping and strengthen other loaded zones. When performing work, the width and height of the Armopoya are supplied, and the manufacturing technology is observed. Properly performed amplification belt strengthens the capital walls of the building and ensures their integrity, compensating for significant loads.
For which armopoyas is designed on aerated concrete
Having enhanced fragility, aerated concrete needs an additional strengthening. At various stages of the construction of aerated concrete walls, a power construction with a wide functional purpose is formed.
The ability to deform the walls and the destruction of the building is minimized when using this carrier element It allows you to:
- create a steady basis for performing fasonry of aerated concrete blocks;
- compensate for efforts that are transmitted by rapid beams;
- prevent the appearance of cracks caused by local deformations;
- ensure the uniform distribution of loads on the bearing walls;
- minimize the possibility of deformation of capital walls under load;
- reduce the effects of wind load on the bearing walls;
- increase the strength of the buildings erected in the conditions of oblique relief;
- prevent violation of the integrity of buildings in seismic zones;
- increase the strength of the buildings on which the reaction of the soil is affected.
The construction of the reinforcing belt has a positive effect on the strength characteristics and the integrity of the aerated concrete structures. It is important for the construction of a reinforcing contour on its own carefully examine the technology of performance of work and, if necessary, consult with professional builders.
Does Armopoyas need for aerated concrete blocks
The need to build a reinforcing belt on aerated concrete walls is due to certain factors that reduce the strength:
- the rafted beams are attached to special anchors to the upper plane of capital walls. In the attachment places, they transmit local efforts that cause the appearance of cracks in gas-concrete walls;
It is especially necessary in a house of aerated concrete built on an inclined soil - the roofing structure in the form of a mounted rafter creates loads acting in a horizontal plane. The reinforced belt perceives the spacer effort and damping them;
- capital walls of the building are subject to uneven shrinkage. This is due to the presence of opening of various sizes. The concrete belt reinforced steel reinforcement restrains the deformation processes.
After analyzing these factors, we conclude that the reinforcing contour is necessary to strengthen the walls erected from aerated concrete blocks. The feasibility of enhancing the carrying structures along the contour of the structure is associated with the characteristics of aerated concrete. It needs to strengthen and only with the help of Aropoyasa can ensure the sustainability of buildings, increasing the strength characteristics.
For which areas it is necessary to enhance a gas-concrete
Blocks made from gas-filled concrete are characterized by reduced strength and require special strengthening with a discharge belt. It is carried out at different heights.
The following sections need a reinforced belt in the additional strengthening of the reinforced belt:
- supporting surface of the foundation of the building. Power edging, located at the lower level, is called a professional term - "Ruralsk". It is formed at the stage of the building of the foundation and repeats the contour of the building. Power edging ensures uniform transmission of loads from the weight of the building, and also perceives the soil reaction;
In order to strengthen the design, the height of the Armopoyas is equalized with its thickness - aerated concrete masonry. The damping belt is constructed between aerated concrete blocks every four rows. Installation of steel rods or laying of a special wire mesh increases the stability of masonry to the effect of deformation processes. Power edging is constructed by pouring the binder solution of steel reinforcement;
- supporting surface of bearing walls. This gain tier perceives the load from overlapping panels, which are in contact with the upper plane of the walls. The solid contour of the reinforced concrete increases the resistance of the aerated concrete structure, preventing cracking. The belt smoothes the load created by slabs of overlapping;
- window and doorways. They need additional strengthening with steel rods with a cross section of 1-1.2 cm. Special grooves perform special grooves to accommodate the rods in the gas-concrete array. Then the steel rods located in the groove are poured with a solution. This allows you to increase the strength characteristics of the openings over which blocks are located.
Increase the durability of the structure by strengthening problem areas, it is possible using a special reinforced belt. Knowing how to make Armopoyas, you can independently fulfill all the necessary work.
Preparing to build a monolithic belt: what is necessary for work
For it is necessary to prepare the following building materials:
- steel fittings cross section 1-1.2 cm. The use of rods of increased diameter allows you to perceive significant loads, ensuring the integrity of the aerated concrete. The rods are placed in the grooves and poured with a solution;
Aropois in the construction sphere is used to increase the resistance of the bearing walls at home by external and internal influence - wire mesh with square sections of 50x50 mm. The amplification is carried out by laying the mesh to the surface of the blocks, followed by the application of a small layer of the binder solution;
- concrete solution. It is used to form a reference contour at the foundation level of the building, as well as for filling the power belt under the elements of the overlap. The solution is prepared using portland cement M400 brand.
When performing work, an annealed wire is required for knitting reinforcing rods used to assemble power frames, as well as a cement solution. It is used to fill the reinforcement grid when the masonry is enhanced.
To perform work, you will need the following equipment and tools:
- concrete mixer;
- bulgarian;
- stroboresis;
- fixture for bending of rods;
- knitted hook.
After preparing tools and materials, you can start performing work.
How to make Armopoyas
Consider the laying technology:
- Perform the grooves of the groove with the help of strokebores.
- Curtain fittings in size using a grinder.
- Remove the construction trash from the received grooves.
- Collect the reinforcement frame and place in the grooves.
- Fill the cavity with the cement mortar, align the surface.
The technology of work is fairly simple. It is important to use high-quality building materials and adhere to the sequence of operations. This will make it possible to independently strengthen the aerated walls.
In essence, Armopoyas on the aerated concrete helps the building to counteract all sorts of loads, and also protects the walls from deformation.
It is a design throughout the perimeter of the upper walls of the structure from reinforced concrete.
It must be created between the overlaps of each floor, as well as before Mauerlat will be laid.
For example, if the house under construction will have two floors, you will need to equip two separate Armopoyais.
The first will be at the junction of the first and second floors, in turn, the second - at the junction of the upper floor and the roof, directly in the place where Mauerlat will be laid.
All work implies several separate stages of work.
Initially, the formwork will be required, which will need to be attached to the walls of the erected structure.
If the reinforced belt on the aerated concrete is created immediately before the construction of the roof, then Maurylalat is stacked on top of it.
This work while complying with the technology and the availability of the entire necessary tool can be done fairly quickly.
Before making a reinforcing belt on a housekeeping, you need to thoroughly understand what it is intended and what important functions performs.
As is known, it stacked on top of the brick and prevents, first of all, the deformation of the wall structures, which can occur due to the movement of the soil, as well as during its shrinkage.
In addition, armopoyas on aerated concrete adds additional strength and stiffness of the entire design of the house.
It should be noted that it also contributes to the uniform distribution of all possible loads along the wall.
Armopoyas helps prevent various point loads that may appear from fastening the beam overlap to the walls of the brick.
By its design, it must be inseparable and monolithic, since only due to it increases the power of the wall resistance to different types of loads, as a result of which they can appear both cracks and deformation.
In most cases, the Armopoyas should be made for those walls that are expelled from gas-silicate blocks.
This is mainly due to the fact that the mounting of Mauerlat to the walls is carried out using anchors or studs, namely, these elements are the main sources of appearance of point loads directly on the blocks from aerated concrete.
If Mauerlat lay on top of the wall without this special belt, then the cracks will be going to go. The same can be said about overlapping beams, which can also become a source of cracks.
In general, Mauerlat is sources of several types of loads, but they can minimize them at the expense of Armopoyas.
In addition, hanging rafters for Mauerlat are additionally loaded blocks of aerated concrete, as a result of which they start expanding, and this protective belt helps evenly distribute all possible loads on the walls.
Preliminary work
Before starting the necessary work on the Armopoyas device on aerated concrete walls of the house, under the beams of overlapping or Mauerlat, with their own hands, you should make calculations and all thoroughly prepare.
According to generally accepted practice, the thickness of the belt takes the same way as directly the thickness of the wall itself, despite that its height is on average equals about thirty centimeters.
At the first stage of works on the Armopoyas device on aerated concrete, the appropriate formwork is performed. For these purposes, a frame of boards should be collected, whose height is taken equal to the height of the belt.
Also, carefully think over each stage of work and conduct preliminary marking around the perimeter of the walls. The Armopoyas device is equally both under the beams of overlapping and under Maurylalat.
You should also prepare all the necessary equipment and tools that may be needed during the work. A concrete mixer will be required for the preparation of the necessary solution.
In the process of work, you will have to take advantage of a special vibration machine, with which it will be possible to eliminate all empties in solution.
It should also be stocking sufficient number of self-tapping screws, fasteners and distant esters. In addition, anchor bolts will be required, they can be replaced with studs of the corresponding sizes.
Kellma type should be purchased, a small inquiry and roulette. From building materials, the gas blocks themselves are needed directly, special glue and fittings in sufficient quantities.
In addition, under the formwork, you need to buy boards and a special snap, as well as strokesa. For the preparation of the mixture of the necessary consistency, sand, crushed stone, water and, of course, are cement.
Prepare all the necessary tools and components, you can proceed to the Armopoya device with your own hands, as shown in the video placed below.
Device formwork
At the first stage, wooden shields should be prepared, which will then need to be attached directly to the walls. Wooden shields are made of boards whose thickness should be at least two centimeters.
Their attachment is carried out by drilling the walls and installing additional screeds with a step equal to sixty centimeters.
This will allow the boards well, as a result of which they will not be able to disperse at the moment when a concrete solution is filling.
The collected shields should be well consolidated along the entire perimeter of the walls.
Also additional fastening of the formwork is carried out using selflessness and knitting wire.
After the walls of the walls are strengthened and tested on the strength of wooden shields, it is possible to proceed to reinforcement.
To the inner space of the formwork should contain reinforcement pins, the recommended diameter of which is about twelve millimeters.
After that, the top layer should be made, which is especially needed if significant loads are supposed.
When conducting reinforcement, it should be remembered that the reinforcement should not touch the edges of the collected design, as well as the top base of the brick.
It is also necessary to remember that all reinforcement connections are carried out with each other with the help of knitting wire, welding is recommended to be excluded.
After the reinforcement frame will be fully assembled and strengthened, it should be set up as soon as possible, using the level.
Order of fill
The final stage on the Armopoyas device on aerated concrete is its fill with cement-based solution.
Pour Armopois without any problems with your own hands. For these purposes, the M200 brand is needed, and one that has a higher brand is suitable.
Of course, it is easiest to order a finished solution, but it is not always financially justified, especially if there is a concrete mixer, you can cook it with your own hands.
For its preparation, you need to take one part of the cement, three pieces of sand and five parts of a large rubble. This is an optimal ratio that will allow you to make Armopoyas on aerated concrete and reliable.
When preparing a solution, water should be gently add to it, as well as to monitor it to be homogeneous. As a result, the solution should be necessary for the necessary consistency.
The order of work on the fill of Armopoyas to aerated concrete can be viewed on the video below.
Pouring Armopoyas on aerated concrete is important to remember what it must be done at a time.
Experts do not recommend pouring Armopianas in several approaches, since in this case it will lose its basic qualities. In the case when the Armopois does not work in one approach, you will have to do special vertical cut-off.
As such a temporary jumper, you can take an ordinary board. Before working on the pouring of the Armopoyas on the aerated concrete will continue, the jumper is removed, and the jock is spilled abundantly by ordinary water.
In the process of work, to exclude the formation of voids inside Armopleois, a special vibrator should be performed regularly, which will help maximize the mixture.
You can shoot wooden shields of formwork at good weather on the third day, after the complete end of the Four of the Armopoyas on the aerated concrete.
It should be noted that Armopois is a mandatory design in the construction of a house of aerated concrete blocks. It is he who helps protect the walls from various influences, and besides this additionally gives the strength of the whole structure.
It is not necessary to save when carrying out work on aropoyash arrangement on aerated concrete, as it may later affect the quality of the house, but also on its durability.
Aropois (reinforced concrete belt) is seismopoyas - Very durable monolithic strip around the perimeter of the building and bearing walls of aerated concrete.
The tasks of Armopoyasa - a significant strengthening of bearing walls to increase their bearing ability, in order to avoid cracks and other deformations due to uneven shrinkage of the building, roofing, wind and other loads.
Armopois firmly fastens aerated concrete blocks, evenly distributes the load and creates stiffness of the structure.
Ideally, geometry, reinforcement and composition of concrete Armopoyash are determined by settlements.
Usually width (thickness) of Armopoyas equals width of the wall, 200-400mm, and the recommended height is 200-300mm.
But it will be wiser to make the width of Armopoyas slightly thinner than the wall so that there was a margin of the insulation, to reduce the bridges of the cold. It is best for this case by extruded polystyrene foam (EPPS), as it is perfectly isolating warmth. There is also an option to fill armooois in already ready-made aerated-concrete U-blocks, but see about it on the text.
- With an uneven shrinkage at home, with seasonal baunisters of the soil, with earthquakes, - Aropoyas keeps the geometry of the building.
- Armopoyas can align the walls horizontally.
- Giving stiffness to the whole building from aerated concrete.
- Local loads are distributed evenly on the bearing walls.
- The high strength of the Armplois allows you to mount all the responsible structures to it, for example, Maurylalat.
Mauerlat must be firmly attached to the carrier walls with studs and anchors. The solo system itself, the weight of the entire roof, snow and wind loads create a significant driving force that can break no reinforced walls. Armopoyas Same Under Mauerlat solves this task, and it is performed in the same way as under the overlap.
- The frame of the belt reinforcement must be continuous.
- Armopoyas should be on all carrier walls.
- Fall of longitudinal reinforcement minimum 800 mm.
- The frame is made of two rows of reinforcement two rods.
- The minimum thickness of the longitudinal reinforcement is 10 mm.
- It is advisable to use long (6-8 meters) reinforcement rods.
- The diameter of the transverse reinforcement is 6-8 mm.
- The step of the transverse reinforcement is 200-400 mm.
- Armature from all sides should have a protective layer of concrete minimum of 5 cm.
- Longitudinal and transverse fittings are associated with a knitting wire.
- At the corners, the longitudinal reinforcement needs to be bending, and try to do next from the corner.
- The frame must be strictly horizontally.
Distance between reinforcement rods calculate the thickness and height of the Armopoyas, taking into account the protective layer of concrete, at least 5 cm on each side.

Armopoyash insulation
Armopoyas is a very serious "bridge" of cold, through which most of the heat leaves, and on which condensate is formed from the inside of Armopoyas. And to avoid this, you need to warm up the external side of Armopoyasi aerated concrete, or polystyolistrol or foam. Polystyrene foam is more preferable. So it is necessary to provide a space for the insulation, pouring armooosas with an indent from the outer edge of the wall.
Warmed Armopoyas under aerated concrete
Concrete which brand to fill armoo
A concrete brand M200-M250 is used to fill the reinforced belt on a gas concrete. It can be brought in the finished form of a mixer from the plant, or to do it yourself.
Proportions for brand concrete M200: Cement M400, Sand, Crushed stone (1: 3: 5). Proportions for brand concrete M250: cement M400, sand, crushed stone (1: 2: 4).
Water in concrete should be the minimum amount, and to impart plasticity, use a plasticizer.
The water-cement ratio should be between 0.5 to 0.7, that is, 10 to 7 parts of water ranges on 10 parts of the cement.
Adding an excessive amount of water to concrete makes it less durable.
To remove air bubbles from concrete, it should be protected by a special construction vibrator, or intensively and long to pour liquid concrete cropping reinforcement.
Concrete must be poured into the formwork at one time so that it is monolithic (inseparable).

The reinforced belt is considered one of the most important stages of building a block house. It is done at the end of each floor. Aropoyas on aerated concrete gives the rigidity of the entire surface of the house, "gluing" the whole design together and strengthening the whole house.
If you doubt your own and skills, you can invite specialists for these purposes, but those who are more oriented in construction business are fully capable of filling Armopoyas, following step-by-step instructions.
How to make Armopoyas on a gas concrete?
To do this, it is necessary to buy voluntary blocks with a thickness of 10 cm. From the outdoor side of the house, blocks are stacked with glue, then from the extruded polystyrene or from mineral wool is arranged with a heat outline. Then, from within the house, blocks 5 cm thick or formwork in the form of plywood are put. As a result, the homemade block is obtained, the reinforcement for Armopoyas is stacked, from 8 to 12 diameter.
It stacked in the form of a rectangle, while the framework knit - on top and from below two rods. On any market, you can purchase special fasteners, which are used in the work. This is done so that the reinforcement does not lie on the block itself, but was in the air - the so-called protective layer of concrete is created, with a gap of 3 cm above and below.
After that, concrete is poured, carefully recalls and it turns out ready-made armoomas under the slab of the overlap. More detailed description can be viewed on video, also in the photo shows drawings, schemes and step-by-step design instructions.
If you carefully look at the entire perimeter, the studs are seen, to which the overlaps will later be attached to keep the roof as soon as possible and not shifted to the parties. Street length depends on the overlap thickness. As a rule, meter elements are taken and in half.
How to fill armoomas with your own hands? This question worries many, especially beginner masters. It is likely that many familiar pictures when concrete is poured from the sleeve - a special concrete pump feeding the material to the right place. But in most cases, the Armopoyas device does not allow this task, since the pressure concrete will fall from a high height, and the formwork can simply burst. Therefore, it is often necessary to use manual work, no matter how hard it is.
When pouring Armopoyasa in a house of aerated concrete, one should calculate the subsequent load. If it is expected not too big, you can save. The volume of the design can be made smaller, but not due to its narrowing, and by reducing the thickness. Experienced masters know how to competently calculate the size of Armopleois and reduce the cost of its manufacture, while not losing the quality of the entire design, which is very important.
As for the fill, there is another important advice. This process should be made by one, and not for several goals. If this is not possible, it is recommended to install special wooden jumpers.
