Precast integral casting #-shaped floor structure

Abstract

The invention relates to a precast integral casting #-shaped floor structure. The precast integral casting #-shaped floor structure comprises a precast laminated secondary beam precast part, a precast laminated frame beam precast part, a precast laminated plate precast part and a laminated cast-in-situ structure. The precast laminated secondary beam precast part and the precast laminated frame beam precast part are in #-shaped and orthogonal arrangement. The precast laminated plate precast part is arranged on the precast laminated secondary beam precast part and the precast laminated frame beam precast part. The laminated cast-in-situ structure is casted on the precast laminated secondary beam precast part, the precast laminated frame beam precast part and the precast laminated plate precast part. The precast integral casting #-shaped floor structure has the advantages of being light and compact in structure, simple and quick in construction, capable of saving labors and materials, low in cost and the like.

Description

technical field [0001] The invention relates to a building component, in particular to a prefabricated integral well-shaped floor structure, which belongs to the technical field of building engineering. Background technique [0002] Well-shaped floors, densely ribbed floors, and beamless floors have the advantages of small beam heights, and are more suitable for buildings with low storey heights. Compared with ordinary floors, although its stress is reasonable and the beam height is small, the number of beams is large, and the external area of ​​the beams is large, which leads to a large workload for the formwork of the concrete cast-in-place structure. Therefore, there are currently One method is to bury lightweight fillers around the beams of the well-shaped floor to replace part of the concrete without force requirements, and then support the horizontal formwork according to the beamless floor. However, in this method, the price of the buried lightweight filler is higher...

Problems solved by technology

[0002] Well-shaped floors, densely ribbed floors, and beamless floors have the advantages of small beam heights, and are more suitable for buildings with low storey heights. Compared with ordinary floors, although its stress is reasonable and the beam height is small, the number of beams is large, and the external area of ​​the beams is large, which leads to a large workload for the formwork of the concrete cast-in-place structure. Therefore, there are currently One method is to bury lightweight fillers around the beams of the well-shaped floor to replace part of the concrete without force requirements, and then support the horizontal formwork according to the beamless floor.

However, in this method, the price of the embedded lightweight filler is higher than that of the alternative concrete, and the embedding process is more troublesome, and problems such as floating and misalignment may occur when the concrete is poured, which is not very ideal. The floor is thicker, there are more reinforcements, the structure has a large self-weight, and the force of the floor is complex, which is not conducive to the structure's earthquake resistance
