It refers to construction and may be industrial building and building at a wide angle.

The circuit of the invention is to reduce the material consumption and improve the quality of the panel.

FIG. I depicts a panel in isometry; in fig. 2 —oz, ate I in FIG. 1. V

In the wall panel on its iieHTpranbnaya: rsi 2 pecho no eHbi there are three differently shaped toothed channels 3, the teeth 4 of which have an angle of 45 - 60 ° and can be rounded off to the “tops” in order to remove the center of it. k

neither The limits of the angular are chosen from technological considerations, when the wall of the panel rvets and the thermal performance of the panel go beyond these limits, the panel is violated.

The diameter D of the circumference described at the tops of the teeth 4 should be no more than 1.4 times the diameter d inside channel 3. Going beyond these limits leads to a reduction in the processability, sound insulation and panel quality.

The axes of the teeth are located at an angle of p 45 to the central axis 2 of the wall panel 1. In the wall panel there are embedded parts 5 for connecting them.

They are made of expanded clay concrete with a cross section from the vibrating plate.

and longitudinal reinforcement, and with embedded parts with external dimensions of 5980x1170x220. Toothed channels with an inner diameter d of 159 mm are made along its central axis from the end along the entire length. All teeth have an angle oi 45 and are located at an angle j3 45 to the central axis of the wall panel. The diameter of the circumscribed circle at the tops of the teeth D 159x1.4 212.6 mm, taken D 208 mm. The figured cog-shaped channels are arranged in increments of h 185 mm.

The presence of an air gap due to the shaped channels that are filled in the body of the panel improves the thermal and sound insulation qualities.

The hollow panel is manufactured using an aggregate-flow technology with a volume of voids up to 60% of its volume. The form is installed on the vibrating plate by means of a crane with a laid reinforcing mesh ,, Concrete distributor, moving along the form, puts into it a layer of concrete mix. After some time, toothed form holders are moved into the mold and include a vibrating platform. Having installed embedded parts, they stack the rest of the concrete mix and turn on the vibroplatform again,

Having laid the concrete, the vibrations are stopped, the toothed shaped formers are removed from the mold and the edges are removed.
