Hollow composite floor slab and construction method thereof
The invention discloses a hollow composite floor slab and a construction method of the hollow composite floor slab. The hollow composite floor slab comprises a prefabricated hollow bottom plate and an upper cast-in-place slab, continuous fully-closed preformed holes and semi-closed preformed holes are distributed in the prefabricated hollow bottom plate at intervals, or the continuous fully-closed preformed holes and plate ribs are distributed on the prefabricated hollow bottom plate at intervals, bottom plate rebars are distributed on the prefabricated hollow bottom plate at intervals in the longitudinal direction and the transverse direction, prestress rebars or prestress rebars and non-prestress rebars distributed at intervals are adopted as the bottom plate rebars, and the rebars penetrate through the semi-closed preformed holes or plate rib preformed holes. Concrete is poured on the prefabricated hollow bottom plate to form the upper cast-in-place slab, multiple sets of top rebars are distributed on the cast-in-place slab in the longitudinal and the transverse directions parallel to the bottom plate at intervals, and reinforced concrete is integrally poured on the bottom plate to form the hollow composite floor slab. Only the prefabricated bottom plate needs to be produced and transported, transportation and installation are convenient and fast, formworks are not needed, the crack resistance and the integrity are good, and the construction efficiency is high.
