Well-type ribbed frame composite floor structure internally provided with light anti-suspension positioning device and construction method thereof

The invention relates to the technical field of light composite floor structures, in particular to a well-type ribbed frame composite floor structure internally provided with a light anti-suspension positioning device and a construction method thereof. The well-type ribbed frame composite floor structure comprises a precast concrete bottom plate and a cast-in-place concrete layer. The precast concrete bottom plate comprises a reinforced concrete lower layer, a well-type ribbed frame concrete upper layer, a polystyrene board, the light anti-suspension positioning device and a reinforced truss. A reinforced net is arranged in the reinforced concrete lower layer, and the reinforced truss is arranged in the well-type ribbed frame concrete upper layer. A well-type ribbed frame structure is formed by connecting the reinforced net and the reinforced truss. The light anti-suspension positioning device is fixedly installed on the reinforced truss. The well-type ribbed frame concrete upper layer is filled with the poly
