Problems solved by technology
[0003] At present, light prefabricated laminated floors generally use lightweight filling blocks to improve the performance of the floor, which can achieve the purpose of enhancing the thermal insulation and sound insulation performance of the floor, and reducing the self-weight of the components, but the prefabricated floor has poor integrity and poor construction quality. Therefore, the development of light prefabricated floor slabs with good integrity and guaranteed construction quality has become a top priority

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 polystyrene board, and the polystyrene board is fixed through the light anti-suspension positioning device. According to the well-type ribbed frame composite floor structure internally provided with the light anti-suspension positioning device and the construction method thereof, the well-type continuous ribbed frame structure is adopted and is filled with the polystyrene board, the structure is stable and low in self weight, the construction procedure is simplified through the simple, convenient and fast light anti-suspension positioning device, and the construction quality is improved.
Description
technical field [0001] The invention relates to the technical field of hollow lightweight laminated floor slab structures, in particular to a well-type rib frame laminated floor structure composed of a prefabricated concrete floor and a cast-in-place concrete layer, with a built-in lightweight body anti-suspension positioning device and a construction method thereof. Background technique [0002] With the improvement of the industrialization of modern buildings, prefabricated structures have been more and more widely used in the field of construction. Ordinary prefabricated reinforced concrete slabs, ribbed slabs, and prestressed slabs can no longer meet the needs of development. The development of lightweight prefabricated laminated panels has effectively alleviated this situation. [0003] At present, light prefabricated laminated floors generally use lightweight filling blocks to improve the performance of the floor, which can achieve the purpose of enhancing the thermal ...
