Transverse rib interlocking concrete superposed rib sandwich floor

The invention discloses a transverse rib interlocking concrete superposed rib sandwich floor. The transverse rib interlocking concrete superposed rib sandwich floor consists of a prefabricated grid sandwich baseplate, a post-cast superposed transverse rib and a post-cast panel, wherein the prefabricated grid sandwich baseplate consists of a panel, a longitudinal rib beam, a transverse rib beam and a light filling block; and the light filling block is clamped in a cavity surrounded by the panel, the longitudinal rib beam and the transverse rib beam. During constructing, multiple grid sandwich baseplates are supported on a beam (or a wall); and then, a prefabricated baseplate and a post-cast superposed layer are superposed to form an integrally assembled transverse rib interlocking concrete superposed rib floor through a post-cast concrete transverse rib beam and a surface layer. The excellent structure performances of the cast-in-place rib floor are achieved; the purposes of industrial production and assembled construction are achieved; and meanwhile, because of the thermal insulation effect of the light filling block, the integration of structure and building energy conservation is realized. The transverse rib interlocking concrete superposed rib sandwich floor has the advantages of low dead weight, good structure performances, high span, good thermal insulation effect and low production cost, and is broad in market application prospect.
