COMPOSITE PRODUCT FOR DESIGNED SLABS Russian patent published in 2012 - IPC E04B5/36 

FIELD: construction.

SUBSTANCE: product for slabs comprises a shell, a metal reinforced frame, one or more strengthening screens from sheet metal. The shell is made of plastic that expands while hardening. The shell has two parallel channels opened on the upper lining and stretching along the entire product length to receive the mixture of the laid concrete. The frame arranged in each channel is formed by two reinforcement rods joined by a row of transverse rods at equal distances. Some transverse rods stretch beyond the limits of the lower reinforcement rod of the frame to form multiple evenly spaced spikes. Spikes have length sufficient for passage via channel foundations and appearance from the surface of the reverse shell side. Strengthening screens have even holes to fix and join the spikes with ends by means of fastening tips that close holes.

EFFECT: design simplification, improved acoustic and thermal insulation characteristics.
