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.

General information

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:

  1. Walls should be erected on a reliable foundation.
  2. During the work process, regularly check the evenness of the structure.
  3. Along the general perimeter of the building, the walls should be reinforced with a reinforced belt made of reinforced concrete.

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:

  • Features and Instruction + Photos and Videos Be in a ring style.
  • Be continuous.
  • Be closed.

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:

  • Protect the walls and base of the building from cracks.
  • Distribution of the load from the roof and additional floors on the walls, giving them strength.
  • Increase the stiffness of the building.

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.

Dimensions

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.

  1. The internal structure must necessarily be reinforced with an armored belt, which has such width values ‚Äč‚Äčthat correspond to the thickness of the wall.
  2. If we are talking about strengthening the house from the outside, the width of the belt must necessarily correspond to the width of the wall, excluding the formwork and insulation.
  3. The minimum value of the height of the structure should be 15 cm, and this figure cannot be more than the width of the wall.

Manufacturing options

It is quite possible to install an armored belt for walls that are built of aerated concrete, and there are several ways for this:

  1. When using wooden formwork.
  2. When using additional blocks.

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:

  1. Features and Instruction + Photos and Videos You have a one-piece reinforced concrete structure.

  2. You have wooden floors and are supported by blocks.

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.

Creation using formwork

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.

Tools and materials

Before starting the construction of the structure, try to worry about purchasing all the required building materials:

  1. Edged boards, minimum permissible thickness 3 cm and wooden beams 40 * 40 in order to make the formwork.
  2. Nails to attach the plank to the wall.

  3. Flexible wire to make the structure rigid.
  4. Rebar rods, the diameter of which should be 1.2 cm.
  5. Use expanded polystyrene as insulation material.

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.

Construction technology

The process involves the execution of work in several steps:

  • Prepare wooden shields.
  • Place a layer of polystyrene between the wooden board and the wall of the house for insulation.
  • Attach the structure to the wall using long nails or self-tapping screws.

  • Supplementary fastening of the wooden structure using wire and self-tapping screws.
  • Assemble the reinforcement cage. First, you should lay the reinforcement pins inside the wooden shield. Use flexible wire to connect the reinforcement to the frame. We do not recommend fastening the reinforcement by welding, as the material may begin to rust inside the concrete.

  • Grouting with cement mortar.

As you can see, there are only 6 steps and the armopoyas is ready.

Reinforcement

Reinforcement is made from reinforcing bars with a diameter of 0.8 to 1.2 cm.

The process is as follows:

  1. Features and Instruction + Photos and Videos Horizontal laying of rods.
  2. Overlapping rods with flexible knitting wire around the entire perimeter of the walls.
  3. Tying the joints with rings of wire, the diameter of which should be 0. 6 cm.

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.

Pouring concrete

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:

  • Crushed stone - 2.

    4 measures.

  • Cement - 0.5 measure.
  • Sand - 1.4 measures.

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:

  1. The pouring should be performed in one cycle and neither in any case, do not interrupt, and also do not allow partial drying of the concrete layer.
  2. Also try to avoid any voids and bubbles in the grout as they may reduce the structural performance in the future.
  3. After pouring, we recommend compacting the concrete using a hammer drill with a special drill bit.

    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.

Creating an unloading belt from blocks

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.

Materials and fixtures

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:

  1. Installation of add-on elements on the wall as usual.
  2. Reinforcement of the central part of the building material.
  3. Pouring cement mortars.

Armopoyas made of bricks

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:

  • When working with a reinforcing mesh, the cross-sectional diameter of which is 0.5 cm, it should be laid through 4 rows of bricks.
  • The width of the structure must be equal to the thickness of the walls that have been processed.

  • The height of the structure will depend on the type of building material of the walls of the house and the type of roof. According to the average size of structures for walls made of aerated concrete blocks, the indicator is 0.4 meters.

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.

Insulation

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.

Tips on organizational issues of object insulation

  1. When creating a structure and planning its further insulation, work should be performed indented from the outer edge of the wall, and not only on it width.
  2. The minimum width of the reinforcing belt should be 20 cm when using monolithic concrete and 25 cm when using bricks.
  3. The resulting free space after filling the unloading belt should be filled with insulation and covered with a foam block, which should be cut out in advance to the required size.

Recommendations of experts

  1. When pouring cement with mortar, make sure that the elements of the reinforced mesh do not touch the walls of the formwork.

  2. To increase the functionality of the rebar unloading cage, install it on the surface using a building level.
  3. For the strength of the concrete, moisturize it constantly after pouring, especially in hot weather. We advise you to moisturize the structure daily for five years. The best effect will be when the surface is covered with plastic wrap after watering.
  4. After a week, the formwork can be removed, but it will function as intended only after 14 days, when the cement mixture has completely solidified.

  5. If you plan to insulate a reinforced belt, do not do it flush. Builders recommend shifting the formwork inward, and then filling the niche with a heat-insulating insulation material.
  6. There is no need to spend money on a reinforced belt if under the foundation of the structure there is soil that is solid and not saturated with water, and the walls are made of bricks. The same is true for single-storey houses with wooden beams rather than reinforced concrete panels.
