Nuclear engineering reinforcement cage composite floor slab and floor

The utility model relates to the technical field of nuclear engineering industrialization and modularization construction, in particular to a nuclear engineering reinforcement cage composite floor slab and a floor, and the nuclear engineering reinforcement cage composite floor slab comprises a reinforcement cage, a prefabricated bottom plate and a post-pouring concrete composite layer; the reinforcement cage is formed by connecting a first reinforcement mesh with a second reinforcement mesh through tie bars and is manufactured in a prefabrication site; the prefabricated bottom plate is formed by pouring concrete on the lower parts of the first reinforcing mesh and the tie bars; and the post-poured concrete laminated layer is formed by pouring concrete on the upper parts of the second reinforcing mesh and the tie bars, and is manufactured on the construction site. The floor comprises a plurality of nuclear engineering reinforcement cage composite floor slabs. According to the method, a reinforcement cage is ma
