Counteraction to loads with armopoyasom on aerated concrete

At its core, armopozas on aerated concrete helps the building resist all kinds of stresses, and also protects the walls from deformation.

It is a construction along the entire perimeter of the upper walls of a building made of reinforced concrete.

It must be created between the floors of each floor, and also before the Mauerlat is laid.

For example, if a house under construction will have two floors, it will be necessary to equip two separate armopoyas.

The first will be located at the junction of the first and second floors, in turn the second one - at the junction of the upper floor and the roof, directly in the place where the Mauerlat is laid.

All work involves several separate stages of work.

Initially, formwork is required, which will need to be fastened to the walls of the erected building itself.

Further on top of the brick inside the formwork it is necessary to make the reinforcement and at the final stage all this is poured with concrete.

If a reinforced belt on aerated concrete was created just before the roof is erected, then a Mauerlat is placed on top of it.

This work with the observance of technology and the availability of all the necessary tools can be done quickly with your own hands.

The main purpose of the

Armopoyas Before you make a reinforcing belt on aerated concrete with your own hands, you need to thoroughly understand what it is designed for and what important functions it performs.

It is known that it is laid on top of a brick and prevents, first of all, the deformation of the wall structures, which can occur due to the motion of the ground, as well as during its shrinkage.

In addition, Armopozas on aerated concrete adds additional strength and rigidity to the entire structure of the house.

It should be noted that it also contributes to the uniform distribution of all possible loads along the wall.

Armopoyas helps to prevent various point loads that may appear from attaching the joist beam to brick walls.

By its design, it must be inseparable and monolithic, because only because of it the force of wall resistance increases to various kinds of loads, as a result of which both cracks and deformation can appear.

In most cases, it is necessary to make an armopause for those walls that are expelled from the gas silicate blocks.

This is mainly due to the fact that the fastening of the Mauerlate to the walls is carried out with the help of anchors or pins, namely these elements are the main sources of the appearance of point loads directly on aerated concrete blocks.

If the mauerlat is laid over the wall without this special belt, then, most likely, cracks will go. The same can be said for floor beams, which can also become a source of cracks.

Generally, the Mauerlat is the source of several types of loads, but due to the armopoyas they can be minimized.

In addition, suspended rafters for Mauerlat are additionally loaded with blocks of aerated concrete, so they begin to expand, and this protective belt helps to evenly distribute all possible loads to the walls.

Mauerlat specialists do not recommend stacking on top of walls without their additional reinforcement.

Preliminary work of

Before starting the necessary work on the construction of an armored convoy on the aerated concrete walls of the house, under the joists or Mauerlat with your own hands, it is necessary to make calculations and carefully prepare everything.

It is necessary to accurately calculate all the geometric characteristics of the erect protective belt.

According to the common practice, the thickness of the belt is taken to be the same as the actual thickness of the wall itself, although its height is on average about thirty centimeters.

At the first stage of the work on the construction of an armored convoy on aerated concrete, a corresponding formwork is performed. For this purpose it is necessary to assemble a framework of boards, the height of which is taken equal to the height of the belt.

Also carefully think through each stage of work and carry out preliminary marking along the perimeter of the walls. The device armopoyasa the same as under the joists of the ceiling, and under the Mauerlat.

You should also prepare all the necessary equipment and tools that you might need during the work. To prepare the necessary solution you need a concrete mixer.

In the process of work it is necessary to use a special vibrovochnoy machine, with which you can eliminate all the voids in the solution.

Also should be stocked with a sufficient number of screws, fasteners and spacers. In addition, anchor bolts are required, they can be replaced by studs of the appropriate size.

You should buy a serrated trowel, a small kyanku and a tape measure. Of the building materials will need directly the gas blocks, special glue and fittings in sufficient quantities.

In addition, under the formwork it is necessary to purchase boards and special equipment, as well as shtoborezy. To make a mixture of the necessary consistency, you will need sand, gravel, water and, of course, cement.

Having prepared all the necessary tools and components, you can proceed to the device armopoyasa own hands, as shown in the video below.

Formwork device

The first step is to prepare wooden boards, which then need to be fastened directly to the walls. Wooden boards are made of boards, the thickness of which should be at least two centimeters.

Their fixing is carried out by drilling a wall and installing additional ties in steps of an average of sixty centimeters.

This will allow the boards to be firmly fixed, as a result of which they can not part at the moment when the concrete solution is poured.

Assembled shields should be well fixed along the entire perimeter of the walls.

Additional formwork fastening is also done with self-tapping screws and knitting wire.

Once the wooden shields have been strengthened and tested on the entire perimeter of the walls, you can start reinforcing.

In the inner space of the formwork should be put reinforcing bars, the recommended diameter of which is about twelve millimeters.

Next, you need to carefully tie up all the armature and put it on a special asterisk. This method will be equipped with a lower reinforcing layer.

After this, you should make the top layer, which is especially needed if significant loads are expected.

When carrying out reinforcement, remember that the reinforcement should not touch the edges of the assembled structure, nor the upper base of the brick.

Also it is necessary to remember that all connections of the reinforcement are carried out by means of a knitting wire, welding is recommended to be excluded.

After the reinforcing cage has been fully assembled and reinforced, it must be set as accurately as possible using the level.

Filling order

The final step in the construction of an armored convoy on aerated concrete is to fill it with a cement-based solution.

You can pour the armopoies without any problems with your own hands. For these purposes, we need concrete grade M200, and one that has a higher brand is also suitable.

Of course, it is easiest to order a ready-made mortar, but not always it is financially justified, especially if there is a concrete mixer, it can be prepared with your own hands.

For its preparation it is necessary to take one part of cement, three parts of sand and five parts of large rubble. This is the optimal ratio, which will make the armopoias on aerated concrete durable and reliable.

When preparing the mortar, you should carefully add water to it, and also make sure that it is homogeneous. As a result, the solution should get the necessary consistency.

The order of work on pouring armopoyas on aerated concrete can be found in the video below.

It is important to remember that it is necessary to do it at a time filling the armopause on aerated concrete.

Experts do not recommend pouring armopoies into several approaches, since in this case it will lose its basic qualities. In the event that pour armopoyas in one approach does not work, you will have to make special vertical cut-offs.

As such a temporary jumper you can take an ordinary board. Before the work on pouring the armored pavement on aerated concrete will be continued, the jumper is taken out, and the joint place is spilled with ordinary water.

In the process of work to avoid the formation of voids within the armpole, you should regularly use a special vibrator, which will help to maximize the mixture.

It is possible to remove the wooden formwork boards in good weather on the third day, after the completion of the filling of the armopoyas on aerated concrete.

It should be noted that armopoyas is an obligatory design for the construction of a house made of aerated concrete blocks. It is he who helps to protect the walls from various impacts, and additionally adds strength to the whole structure.

It is not necessary to save money when carrying out the work on the arrangement of the armored pavement on aerated concrete, as this can subsequently affect not only the quality of the house, but also its durability.
