STEEL-CONCRETE COATING SLAB Russian patent published in 2025 - IPC E04B5/40 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used as a bearing structure of coatings and floors of buildings and structures. In the steel-concrete plate, V-shaped spacers are attached to the steel flooring in a staggered order by means of arc-shaped bolts. Divergent ends of the spacers are connected by means of nodal elements with horizontal belt rods to form a lower belt mesh, the joint operation of which increases the bearing capacity of the concrete slab for bending. Presence of arc-shaped bolt elements in the body of the concrete slab, which are connected to the reinforcing mesh, increases combined shear operation of the concrete slab and the steel sheet.

EFFECT: increasing bearing capacity of steel-concrete slab.
