The existing floor forms mainly comprise cast-in-situ floor, steel bar truss floor supporting plates, composite floor slabs and the like. The cast-in-situ floor slab requires a large amount of site template operation and concrete pouring wet operation, and does not meet the requirements of rapid industrial construction and environment protection. Both the steel truss floor deck and the composite floor are one of the forms of prefabricated assembled floor, and there are several problems in the last few years of application. The steel bar truss floor carrier plate is relatively successful in public buildings, but is limited in use in houses due to the influence of the galvanized steel sheet of the basement membrane. Although the composite floor slab has good aesthetic property and stress performance, in order to ensure the integrity of the composite slab, the thickness of the floor slab is generally larger than 150mm, so that the composite floor slab is not suitable for residential buildings with the common thickness of 100-120 mm. The steel bar truss floor carrier plate and the composite floor slab have the advantage of rapid industrialized construction to a certain extent, but the field concrete wet workload is still larger.
