FIELD: construction.
SUBSTANCE: invention relates to the field of construction, in particular to reinforced concrete slab. Reinforced concrete slab comprises shell with camber facing slab top and contour ribs solidly joined to it. Shell is arranged as ribbed on both sides, and contour ribs are arranged along the whole perimetre of slab. Shell is equipped with longitudinal and transverse ribs arranged along slab height and forming upper and lower surfaces of slab with cellular shape. Upper surface of slab is formed by grooves stretched in transverse direction and symmetrically arranged relative to axes. Grooves are formed by transverse ribs arranged on outer surface of shell. Lower surface of slab is equipped with grooves in longitudinal and transverse directions. Grooves are formed by longitudinal and transverse ribs arranged on inner surface of shell.
EFFECT: reduced consumption of concrete and reinforcement, reduced labour expenses in manufacturing of floor slab and increased bearing capacity in crossbar-free assembly.
