Fabricated tube well steel floor slab structure and construction method thereof

The invention provides a fabricated tube well steel floor slab structure and a construction method thereof, and belongs to the field of building construction. According to the technical scheme, the floor slab comprises a floor slab unit and a plurality of positioning sleeves arranged on the floor slab unit, tube wells are arranged in the positioning sleeves, limiting hanging pieces are arranged between the tube wells and the floor slab unit, tube well limiting pieces are further arranged on the positioning sleeves, and hoisting assemblies are arranged at the tops of the tube wells in the positioning sleeves. The tube well steel floor slab structure has the beneficial effects that the tube well steel floor slab structure is assembled and prefabricated, meanwhile, the prefabricated floor slabs and the adjacent prefabricated floor slabs are connected together, a complete floor slab structure is formed, quality improvement, efficiency improvement and construction period shortening are facilitated, the tube well i
