Prefabricated assembly type steel plate-concrete composite shear wall structure system and construction method thereof

Abstract

Provided are a prefabricated assembly type steel plate-concrete composite shear wall structure system and a construction method thereof. The prefabricated assembly type steel plate-concrete composite shear wall structure system comprises prefabricated steel plate-concrete composite shear walls, prefabricated steel rib-concrete composite beams, composite floor slabs and composite floor slab installation supports; the vertically-arranged prefabricated steel plate-concrete composite shear walls are connected with the prefabricated steel rib-concrete composite beams and the composite floor slabs through the composite floor slab installation supports; and the prefabricated steel plate-concrete composite shear walls are connected through bolted steel plates. Longitudinal stress rebars in components are omitted, so that grouting sleeve connection of the longitudinal rebars in an assembly type concrete structure is avoided, the construction process is simplified, and the structure construction cost is reduced. The outer sides of the steel plates or the steel ribs in the composite structure are all protected by concrete, so that the rust prevention and fire prevention cost caused by exposure of steel in structural steel buildings is avoided, and durability of the structure is improved. The prefabricated assembly type steel plate-concrete composite shear wall structure system is suitable for assembly type high-rise residences, component connection nodes are constructed simply, stress is reasonable, installation is convenient and rapid, the assembly degree is high, and construction is rapid.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated assembled steel plate-concrete composite shear wall structure system and a construction method thereof. Background technique [0002] At present, prefabricated residential systems mainly include prefabricated frame systems and prefabricated shear wall systems, and frame structures are not suitable for high-rise residential structures. In the frame structure, the load is concentrated on the frame column. The column section generally adopts a rectangular section, a circular section or an I-shaped section. When the column bears a large vertical load, the section size is much larger than the thickness of the wall, and the corners of the column will appear in the room. , reduce the utilization rate of building space. The shear wall disperses the force, so the wall is thinner, which solves the problem of exposed columns, and because the existence of th...

AI Technical Summary

Problems solved by technology

[0005] 1. The steel beam and steel column section of the prefabricated frame structure is large in size, and there are exposed column edges and corners in the room, which affects the use of building space

[0006] 2. The on-site docking of the precast concrete shear wall system is difficult. If the longitudinal reinforcement in the upper and lower shear walls is not firmly connected, there will be a great safety hazard

[0007] 3. The ordinary steel plate shear wall system has problems such as fire prevention and corrosion protection, cold and hot bridges, and large steel consumption, and is prone to buckling under the reciprocating tension and compression of earthquakes.
