A fully prefabricated steel tube concrete shear wall and building structure system

Abstract

The invention relates to a fully prefabricated concrete-filled steel tube shear wall and a building structure system. The shear wall includes horizontally distributed steel bars, vertically distributed steel bars, steel pipes, horizontal panels and prefabricated concrete. The horizontally distributed steel bars and vertically distributed steel bars form the wall. The steel skeleton of the body; the steel pipes are vertically arranged in rows along the length of the wall in the steel skeleton; the horizontal slabs are vertically distributed horizontal slabs, and the two ends of the horizontal slabs are respectively welded and fixed to the steel pipes on both sides; the steel skeleton , steel pipes and horizontal panels are assembled in the factory, and concrete is pre-cast in the steel skeleton and steel pipes. In addition to the advantages of high bearing capacity, high rigidity, good anti-seismic performance, and excellent anti-corrosion and fire-proof performance after the combination of steel and concrete, the shear wall of the present invention also has the advantages of being able to form wall columns of various shapes, flexible use positions, The structural components are light, the transportation is convenient, and the on-site construction is convenient.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated structure, in particular to a fully prefabricated steel tube concrete shear wall and a building structure system. Background technique [0002] At present, in domestic buildings, reinforced concrete shear walls are widely used, mainly in shear wall systems, frame-shear wall systems, frame-core tube structural systems, tube-in-tube structural systems, etc.; in steel structures, steel plate shear walls Wall, steel plate composite shear wall, square steel tube beam shear wall, etc. also have certain applications. [0003] There is following shortcoming in prior art: [0004] 1) The cast-in-place reinforced concrete shear wall belongs to the traditional production method, which consumes high resources and energy, causes great environmental pollution, is labor-intensive, and has low production efficiency; [0005] 2) The prefabricated reinforced concrete ...

AI Technical Summary

Problems solved by technology

[0004] 1) The cast-in-place reinforced concrete shear wall belongs to the traditional production method, which consumes high resources and energy, causes great environmental pollution, is labor-intensive, and has low production efficiency;

[0005] 2) The prefabricated reinforced concrete shear wall belongs to the industrial production method, but the cost is high, the connection structure is relatively complicated, the quality of the connection joint project is not easy to control, the bearing capacity is low, the ductility is poor, and the self-heavy weight of the components makes transportation, hoisting and installation inconvenient;

[0006] 3) Reinforced concrete shear walls are self-heavy, the seismic performance is average, and the construction speed is slow. Sometimes the large cross-sectional size of the components has a certain impact on the building space and quality

[0007] 4) The steel plate shear wall uses a large amount of steel, the cost is high, the anti-corrosion and fire protection performance is average, the comfort is poor, and the adaptability to the filled wall is general, so its application is greatly restricted

[0008] 5) The amount of steel used in the steel tube beam shear wall is relatively large, and the cost is relatively high

[0009] 6) In the steel plate composite shear wall, the steel plate has weak constraints on the concrete, the steel consumption is large, the cost is high, the structure is complex, the construction is difficult, and the construction period is long
