The composite floor slab is used as a main component in an assembly type building, and has the characteristics of material saving, convenient and fast construction, green and environmental protection. The laminated floor slab is an assembled integral floor slab formed by laminating a bottom plate (prefabricated plate, also called a non-dismantling formwork) and a cast-in-place reinforced concrete layer. The bottom plate is one of the components of the floor slab structure and is a permanent template of the cast-in-place reinforced concrete laminated layer. The bottom plate is used as a bottom die of a cast-in-place concrete layer, a template does not need to be supported by the cast-in-place layer, the bottom surface of the bottom plate is smooth and flat, and the ceiling can be not plastered any more after plate seams are processed.
