Description

The invention relates to the construction and can be used in the coatings of industrial, residential and civil buildings.

Known coating panels of heavy ^{5 * * * *} concrete [1].

Such panels have a large bulk density, low heat transfer resistance, high cost / When using these panels to cover buildings, the roof ^{10 * * * *} must be insulated with expanded clay backfill! koi or other heat-insulating materials.

The disadvantage of these panels is the overspending of materials. ^fifteen

Closest to the Invention, the technical solution is a coating panel comprising a slab of aerated concrete reinforced in the longitudinal direction [2]. 20

These panels are both load-bearing and heat-insulating coating elements. Panel reinforcement is pre-treated with anti-corrosion compounds. 25

The disadvantages of such panels are low rigidity, increased crack formation, the need for corrosion protection of valves, high cost. thirty , . .2

The purpose of the invention is to increase the rigidity and crack resistance, reduce the cost of the panel.

In addition, the invention does not require protection of the reinforcement from the corrosive effects of the environment.

This goal is achieved by the fact that in the payel’ coverage, including a slab of aerated concrete, reinforced in the longitudinal direction, the reinforcement is made in the form of polymer concrete bars with metal rods placed in them.

'In FIG. 1 shows a gas-foam concrete coating panel, General view; in FIG. 2 is a diagram of the reinforcement of a polymer concrete block; in FIG. 3 - polymer concrete block, cross section.

The aerated concrete slab 1 is equipped with polymer concrete bars 2 with metal rods 3 placed therein.

Polymer concrete blocks are equipped with mounting loops 4 and clamps 5, preventing the displacement of the rods during concreting.

In the manufacture of the panel, polymer concrete bars are prefabricated. The grade of polymer concrete is 800. Zinc dust is added to the polymer concrete mixture to reduce shrinkage deformation. .
