High performance concrete reinforced steel truss floor slab is an integrated composite floor slab composed of reinforced steel truss and non removable concrete bottom formwork. During the construction phase, the composite building should have slabs that can withstand wet concrete and construction loads; After the concrete pouring of the floor slab is completed, the steel truss serves as the load-bearing steel bar during the use stage of the floor slab, and the concrete bottom mold is not disassembled, forming a concrete interface at the bottom of the floor slab. In the later stage, it can be directly decorated and decorated, greatly saving construction time and comprehensive cost
