BUILDING SLAB Russian patent published in 1997 - IPC

FIELD: construction, in particular, building reinforced - concrete slabs, for instance, floor slabs. SUBSTANCE: the building slab uses a reinforcing framework of longitudinal stressed reinforcement, volumetric right- angles spirals enveloping it in the slab butt ends and located along the stressed reinforcement, and vertical frameworks and vertical frames pushed in the spirals, flat V-shaped or zigzag spirals located in the volumetric right-angles spirals in the plane parallel to the stressed reinforcement. The vertical frames have a square or U-shaped profile. The building slab has assembly loops having a V-shape or made in the form of twin two-branch loops. The slab is furnished with an upper mesh, which may be flat spiral loop-shaped with parallel or inclined loop branches. EFFECT: enhanced strength of slab supporting sections, reduced specific quantity of metal and labour content. 5 cl, 6 dwg
