A steel-concrete beamless floor comprises a flat metal sheet with flange portions, at its plane notches are arranged, and a concrete layer placed on the metal sheet. The notches are E-like in shape. The middle one of the notches has length smaller compared to the side ones. The edges of the E-like notches are bent towards the concrete layer with formation of anchor supports as tabs that form with the plane of the metal sheet an angle smaller than 90°. The ends of the tabs are bent by depth of the central cut of the notch in opposite directions, with formation of shelves normal to the plane of the tab. Foamed concrete is used as concrete. |
