The invention relates to the construction and can be used in the manufacture of wall panels from a material with a large linear shrinkage factor, for example, from cellular concrete, autoclaved and non-autoclaved hardening or porous concrete, characterized by good heat insulating ability, relatively small bulk weight, sufficient strength.

A wall panel made of cellular concrete is known, which includes a web, wall blocks, and a continuous element connected by prestressed weights (1.

Such a wall panel is made integral due to the shrinkage of cellular concrete, which makes it labor intensive.

When large-sized products in the form of wall panels of room size are made from cheesed concrete, their shrinkage during the hardening process, which continues and after the manufacture of the product, develops, which leads to cracking of the panels during operation and contributes to their premature wear. To reduce shrinkage in the panels, they are reinforced with steel meshes or coated with special porous plasters containing dispersed additives from chopped fiberglass, metal wire, etc.

Closest to the offer is a wall panel comprising a layer of cellular or porous concrete and reinforcement, which can be made in the form of reinforcing metal grids, laid over the entire panel area, or of three layers: cellular or porous concrete, finishing (layer of plaster) and in the form of a fibrous mat made of metal fibers, laid over the entire area of the fibers, laid over the entire area of contact with the finishing layer 2.

This partly improves the quality of the products, however, does not eliminate the uncontrollable process of cracking due to shrinkage, which leads to additional expenditure of material for structural reinforcement.

In addition, the application of porous plasters (finishing layer) is difficult, and the plaster itself requires constant maintenance.

The purpose of the invention is to improve the quality of the panel by limiting the shrinkage of concrete, as well as reducing the consumption of metal for reinforcement, and increasing architectural expressiveness.

The goal is achieved by the fact that the wall panel, comprising a layer of cellular or porous concrete and armature, is equipped with a separator layer of concrete, made in the form of at least two rows of cells whose cells are shifted relative to each other.

In this case, the cells of cells are shifted one relative to another by an amount equal to half of the size of the cell.

The walls of the cells are inclined relative to the plane of the panel.

Honeycombs are made of bituminized cardboard ..

In addition, the honeycomb made of fiberglass.

The wall panel is made with a reinforcing mesh located between rows of cells.

FIG. 1 shows the proposed wall panel, a general view; in fig. 2 -, section A-A in FIG. .one; in fig. 3 - separate elements of the panel, laid in the form before pouring concrete; in fig. 4 - wall panel, option; in fig. 5 - section bb in fig. 4; in fig. 6 - honeycomb, top view; in fig. 7 is a section bb of FIG. b; in fig. 8 - honeycomb, axonometrics.

The panel includes a layer of cellular or porous concrete 1 and reinforced mesh 2, a separator of a layer of concrete, made, for example, in the form of two rows of cells 3, the cells 4 of which are shifted one relative to the other.

The panel is made as follows. .

In the form 5, a separator of an array of concrete is made, made in the form of honeycombs 3, which, in order to save metal, are made of bituminized cardboard, fiberglass or other material. Honeycombs 3 are placed on the bottom of the form 5 in two layers: first the lower layer, then on it the reinforcing mesh 2, above - the upper layer. Moreover, the cells 4 cells 3 of the upper layer are offset relative to the cells 4 lower slab

by an amount equal to half the cell size 4.

Between the side walls 6 of the form 5 and the layers of the cells 3 there is a gap 7 in which the reinforcement cages 8 are placed.

Then the mold 5 is poured with concrete 1 and, it is foamed. In this case, a lining 9 is formed along the walls b of the mold 5, which stiffens the outer face of the panel.

The supply of the panel with honeycombs leads to the fact that cracks do not develop over its entire surface, as in known structures, but are localized within cells of cells, i.e. purposefully organized and shrinkage of concrete occurs strictly along the line formed by the walls of 10 cells 3. Since cell cells are small in plan compared to panel dimensions, shrinkage cracks are also small (0.1-0.2 mm wide for panel size 2, 8 x 6 m) and do not render

negative impact on the strength properties of the panel.

The offset cell cells prevents the development of cracks in the depth of the panel, as well as

| Provides a reliable connection between the individual blocks 11 of concrete, the inner and front sides of the panel.

Making the cell walls inclined relative to the plane of the panel also eliminates the possibility of its through cracks developing in depth.

Thus, supplying the panel with an array splitter, made in the form of relatively shifted. each other, a row of cells, allows you to organize the process of setting up concrete and, therefore, not only improve the quality of the panel. But also to reduce the consumption of material for constructive reinforcement. Thus, instead of two reinforcing meshes, only one is required, and in some cases, jjfx, you can do without the mesh and as a reinforcing element use only a frame along the contour of the panel necessary to form a tie. In addition, these cells can also be used to enhance the architectural expression of the panel if their faces are drawn onto its front side (Figs. 1 and 4).
