Assembled shear wall formed by combining square steel pipes with steel plate concrete

Abstract

The invention discloses an assembled shear wall formed by combining square steel pipes with steel plate concrete. The shear wall includes a frame structure formed by vertical girders and cross beams;the vertical girders include special-shaped square steel pipe groups (1) and single square steel pipes (2); the cross beams include H-shaped steel girders (3); the H-shaped steel girders (3) are welded to the special-shaped square steel pipe groups (1) or the single square steel pipes (2) to serve as interlayer cross beams; bidirectional connectors (4) above the H-shaped steel girders (3) enable the upper and lower layers to be communicated with each other; steel plates (5) are welded to the two side surfaces of a square space formed by the H-shaped steel girders (3) on the upper layer, the bidirectional connectors (4) on the lower layer and the special-shaped square steel pipe groups (1) or the single square steel pipes (2) on both sides; concrete (8) is poured between the two steel plates (5). The arrangement is flexible, the stress is clear, the lateral resistance capability of a structural system is obviously improved, a steel plate concrete combined structure and the frame structure can cooperatively work and can be compatibly deformed, two quakeproof defense lines are formed, and the quakeproof performance is reliably ensured.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to an assembled square steel tube steel plate concrete composite shear wall. Background technique [0002] At present, the structural systems often used in high-rise residential buildings include shear wall structure, frame-shear wall structure, frame support-shear wall structure, etc. Or introduce a shear wall system with stronger lateral stiffness into the super high-rise structure. Reinforced concrete shear wall is one of the most commonly used shear wall forms in structures at present. It is favored by the majority of designers for its advantages of good integrity, high rigidity, small lateral deformation, and good resistance to wind load and small and medium-level earthquakes. , but its own shortcomings are also prominent, such as excessive stiffness, low ductility, early cracks, shear damage in the later stage of stress, and difficult repair after earthquakes.

Reinforced concrete shear wall is one of the most commonly used shear wall forms in structures at present. It is favored by the majority of designers for its advantages of good integrity, high rigidity, small lateral deformation, and good resistance to wind load and small and medium-level earthquakes. , but its own shortcomings are also prominent, such as excessive stiffness, low ductility, early cracks, shear damage in the later stage of stress, and difficult repair after earthquakes. In addition, the size of reinforced concrete shear walls The weight and self-weight are relatively large, which not only increases the burden of the structural foundation but also wastes the indoor area

The on-site construction process needs to support formwork, tie steel bars and other processes, and the efficiency is relatively low

[0003] The other type of double-steel plate concrete composite shear wall is mostly a vertical through structure, and is connected to the floor through reinforcement holes at the floor position. The joint strength of the connection between the wall and the floor is weak, and the seismic performance is poor.
