Armopoyas made of bricks on the walls: features + Photos. What is an armopoyas for? A reinforced belt is a monolithic type structure that is located along the entire perimeter of the building.
Armopoyas on aerated concrete made of bricks helps to protect walls from deformation and destruction due to the influence of heavy loads. The technology of strengthening the surface of the walls of the object means laying a belt, which will "unload" the walls from excess load between the floors of each floor and to the places where the roofing masonry passes.
Read more below for details.
Aerated concrete is a great alternative to ordinary brick. But, unfortunately, in terms of strength, aerated concrete blocks are worse than bricks, since the material does not hold fasteners on the surface poorly. Aerated concrete block masonry has its own interesting features:
When carrying out construction work in violation of technological rules, cracking of blocks may begin due to high roof pressure.
In order to provide a functional armored belt, its structure must necessarily comply with the following characteristics:
The main components of the armored belt are concrete mix, a frame made of reinforcement and blocks (or formwork).
The purpose of the structure is to:
This design helps to ensure the reliability and strength of the load-bearing wall, as well as to increase the building's resistance to the effects of wind, seismic vibrations, temperature extremes, shrinkage of the earth and the building itself.
The dimensions of the brick reinforcement belt will depend on the design features of the material to which the fastening will be made.
Walls can be external and internal.
For certain categories, builders consider certain requirements that relate to the size of the structure.
It is quite possible to install an armored belt for walls that are built of aerated concrete, and there are several ways for this:
If we compare both of these methods, it should be noted that the equipment of walls using an armored belt with wooden formwork is more difficult to carry out from a technological point of view. The second method, in which it is proposed to use additional blocks, is many times easier, but then you will have to invest more funds, since you will use expensive building materials.
An unloading belt is not laid if:
If you use wooden floors, it will be enough to pour concrete platforms with a thickness of 5 cm under the beams, which will play a supporting role in order to reliably protect the building blocks from punching. In reinforced concrete structures, there is simply no point in making additional protection, since the existing load will be evenly distributed.
The formwork for an armored belt is a frame made of wooden components. It is made from scraps of boards that are fastened together on the outside.
When the complete formwork is being assembled, the lower part is fixed with self-tapping screws to the wall, and the upper one with the help of transverse board ties at intervals of 1.8 to 2 meters. The screed is required in order to give the structure reliability, otherwise it can be crushed or deformed when pouring concrete.
Before starting the construction of the structure, try to worry about purchasing all the required building materials:
Before starting work on the manufacture of an armored belt from brick to aerated concrete, we advise you to draw a diagram of the future structure and indicate the planned dimensions.
Based on the drawing, you can calculate the amount of building materials that may be required. From construction tools, in this case, you will need a hacksaw for metal and a drill.
The process involves the execution of work in several steps:
As you can see, there are only 6 steps and the armopoyas is ready.
Reinforcement is made from reinforcing bars with a diameter of 0.8 to 1.2 cm.
The process is as follows:
Tying the reinforcing rods should be done on the formwork itself.
In the finished form, the reinforcement frame is quite heavy. When performing a separate assembly of the structure, it will be difficult to lift it and even more so to place it. We recommend laying a layer of brick or stone between the frame and the aerated concrete blocks of the reinforced belt.
When buying dry concrete mix, pay attention to the marking, as it must be no lower than M200.
If there is no such product in the store, you can make it yourself at home, if you buy other components and mix them in the right proportion:
To increase the density of the composition, you can replace crushed stone with gravel. After the dry elements are mixed, you should start adding a little water in portions, and its amount should be 20% of the total mass of the mixture.
In the technology of concrete pouring, there are certain work standards that should be performed in order to obtain the desired functional result:
In order to eliminate voids in the solution, they use a special vibrating machine, and if it is not there, you will have to remove all air bubbles by stitching the solution with fittings.
As formwork, you can use not only wooden structures, but also blocks of aerated concrete U-shaped forms. But in this case there is a necessary condition for the building material, namely the presence of an internal cavity, which will be required for laying the reinforcing cage and pouring concrete.Trough type blocks should be laid with the same width as the walls. Such a belt will be conveniently arranged to the outer walls due to the performance of an additional function of insulation by them, while all cold bridges will be excluded.
Since the method is quite simple, to create an armature belt from bricks for walls and its reinforcement, you just need to buy building materials - additional blocks with a thickness of 10 see Before you buy material, you should perform calculations of the required amount of material for the planned height of the structure and the perimeter of the object.
Manufacturing process using add-on blocks:
A belt for unloading can be made using brickwork, which will be reinforced with a reinforcing mesh.
It is slightly worse than concrete and can only be used for small outbuildings. In order to increase the strength indicators of a brick structure, it is advised to use a metal welded mesh or reinforcement.
The features of the structure are:
Strengthening the walls with bricks with a reinforcing mesh cannot replace the full-fledged giving of reliability to structural elements using an analogue of reinforced concrete.
The most important feature of aerated concrete is that it has a low thermal conductivity, which will ensure the absence of the freezing factor of the built structure even at the lowest ambient temperatures.
For this reason, when constructing a reinforcing structure, it is important that they do not in any way violate the thermal insulation properties of the house. In winter, as well as in those periods when constant sudden changes in temperature are not uncommon, condensation may appear on the brick armopoyas. To avoid this, we advise you to carry out insulation work.
Expanded polystyrene, foam and mineral wool (mats) can be used as elements for creating thermal insulation. In some cases, you can use aerated concrete blocks that have partitions.
When using mineral wool, leave small ventilation gaps between the cladding surface and the insulation.
