Prefabricated concrete composite floor slab
The invention relates to a prefabricated concrete composite floor slab, which comprises a prefabricated slab and embedded steel beams embedded in the bottom surface of the prefabricated slab, wherein each embedded steel beam is cap-shaped steel or U-shaped steel with the identical cross section shape, and completely or basically penetrates through a main body of the prefabricated slab; a plurality of embedded steel beams are in parallel arrangement in rows; a pair of outwards flanged upper wing slabs and partial web slabs of each embedded steel beam are embedded inside the prefabricated slab; the rest web slabs and lower wing slabs are hung under the bottom surface of the prefabricated slab; and steel wires, steel nets, steel plates or section steel is welded on a pair of upper wing plates of each embedded steel beam. The prefabricated concrete composite floor slab has the advantages that the steel beams are embedded in the prefabricated slab; the anti-bending bearing capacity and the rigidity of the floor slab are greatly enhanced; the thickness of the prefabricated slab is reduced; the weight of the floor slab is reduced; the cost is reduced; the prefabrication of floor slab production is realized; and the field installation of the floor slab becomes convenient, fast and reliable.
