Armopoyas for aerated concrete, as well as for other types of building materials, is intended to strengthen the building, which allows to increase the resistance of the latter to increased loads. It also prevents deformations associated with uneven shrinkage of the building itself and the soil beneath it, from wind exposure and temperature changes. This is a monolithic reinforced concrete structure located along the entire perimeter of the structure.
Why make an armored belt for aerated concrete?
This procedure is mandatory, and there are a number of reasons for this. It is worth telling about them in more detail. During the construction of the roof truss structure, the Mauerlat is attached to the wall with anchors and studs that create a point load. Aerated concrete is unable to cope with such a load, and because of this, cracks can appear in the blocks. If we are talking about the use of hanging structures in the rafter system , then an additional load is created on the walls. It has a bursting effect. Armopoyas for aerated concrete in this case is necessary not only to give rigidity to the frame, but also to distribute the load on the whole house.
If the beams of the rafter system are laid directly on aerated concrete, this can lead to a number of troubles. In the absence of an armored belt, the slightest deviation of the roof level may well cause a point load, which leads to the formation of cracks.
When constructing two-story buildings, it is required to arrange several reinforcing belts, at least two. Their exact amount depends on the selected material for the construction of walls. Be sure to arrange an armored belt for aerated concrete between the first and second floor, which is associated with the support of the ceilings on it. Between the second floor and the roof it is also necessary. It is possible that it will be necessary to make an armored belt for the foundation.
You should figure out how to do this. Typically, the formwork for the reinforcing belt is made in the form of a frame made of boards fastened on the outside. This method is not only the simplest, but also most often used. Usually enough height is 30 centimeters, and its thickness should not exceed the width of the wall. Or you can make it a little narrower. The lower part of the formwork is fixed to the wall by means of self-tapping screws, and on the top it is necessary to use cross ties every 80-100 centimeters. This will allow the structure to hold concrete during pouring.
If you are interested in further warming the walls, then the armored belt for aerated concrete should not be flush, it is better to shift the formwork a little deeper. These niches will then be filled with insulating material.
If concrete slabs will not be used as an overlap, then it is enough to make a frame from a pair of reinforcement rods that are connected by jumpers. It will be made in the form of a short flight of stairs. At more significant loads, a more reliable frame should be made, consisting of four rods, in the context of the appearance of a square. If we talk about how to make an armored belt, then it is important to say that for this you can use the ready- mixed concrete mix. At the same time, its marking should be M200 and higher.
In 4-5 days, the armo-belt will be ready, after which it will be possible to remove the formwork.
