STEEL-CONCRETE FLOORING Russian patent published in 2025 - IPC E04B5/23 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used in the manufacture of steel concrete structures of coatings and ceilings of buildings and structures. In the steel-reinforced concrete ceiling, which includes metal beams installed with a certain pitch, each of the beams is made composite from bent profiles of the C-shaped section connected by walls. Sheets of steel profiled sheeting of certain size are laid on the beams, on which there is a concrete slab formed from monolithic concrete and connected to the beams by means of anchors. Sheets of profiled sheet are made with flanges at the ends, and flanges of C-shaped profiles are made with cutouts that repeat the pitch of arrangement of flanges of ends of sheets of profiled sheet. Flanges of ends of profiled sheeting are inserted into shaped cuts of shelves of C-shaped profile.

EFFECT: increasing bearing capacity of steel-concrete covering.
