Abstract

The invention discloses a beamless hollow floor-cavity steel pipe concrete shear wall composite structure system and method, which solves the problem of slow construction speed in the prior art, and has the beneficial effects of high assembly efficiency and high overall stability of the building. The scheme is as follows: including shear walls, including multiple walls that can be assembled in sequence; beamless hollow floor, including steel cages, membrane shells and steel mesh, the steel cages are fixed to the shear walls, and the steel cages include criss-crossing Multiple horizontal reinforcement cages and multiple longitudinal reinforcement cages, the adjacent horizontal reinforcement cages are set at a set distance, and the adjacent longitudinal reinforcement cages are set at a set distance; the membrane shell, hollow inside, is set between the horizontal reinforcement cage and the longitudinal reinforcement cage In the space between the cages; the reinforcement mesh is set on the upper surface and the lower surface of the reinforcement cage, and concrete is poured on the surface and inside of the reinforcement cage and the reinforcement mesh; Connected tiles.

Description

technical field [0001] The invention relates to related fields of construction, in particular to a beamless hollow floor-cavity concrete-filled steel tube shear wall composite structure system and method. Background technique [0002] Prefabricated buildings refer to buildings assembled on site with prefabricated components. Compared with traditional construction, this kind of building has the advantages of fast construction speed, less restricted by climatic conditions, labor saving and improved construction quality. [0003] Concrete has high compressive strength. However, the bending resistance is very weak, while steel, especially section steel, has strong bending resistance and good elastic-plasticity, but it is easy to lose stability and lose axial compression resistance when it is compressed. Concrete-filled steel pipe can combine the advantages of the two in structure, which can make the concrete in a state of lateral compression, and its compressive strength can be...
