FIELD: construction, particularly building elements of relatively thin form for the construction of parts of buildings, for example, sheet materials, slabs, or panel. ^ SUBSTANCE: roof slab comprises longitudinal metal ribs, perforated frame members made of thin-walled profiles and heat-insulation made as monolithic panel. Longitudinal rib walls are provided with slots. Frame member ends have cuts for end insertion in longitudinal rib wall slots. Frame members also have transversal notches for thin-walled profile retention by profile rotation or bending of profile edges projecting beyond the slot. Thin-walled profiles are arranged at different longitudinal rib cross-section heights in longitudinal direction of the ribs. Monolithic panel has thickness exceeding longitudinal rib cross-section height. ^ EFFECT: decreased metal consumption and structural height of roof slab cross-section. ^ 3 dwg |
