Background technique

Well-shaped floor, ribbed floor, and beamless floor have the advantages of small beam heights, and are more suitable for buildings with low storey heights. But for well-shaped floors such as well-shaped floors and dense-rib floors, compared with ordinary floors, although the force is reasonable and the beam height is small, the number of beams is large, and the external area of the beams is relatively large. , resulting in a large workload for supporting the formwork of the concrete cast-in-place structure. Therefore, there is currently a way to bury lightweight fillers around the beams of the well-shaped floor to replace some concrete that has no force requirements, and then support the horizontal formwork on the beamless floor. However, in this method, the price of the buried 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 during concrete pouring, 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.
