Pull-joint type double-steel-plate composite shear wall

Abstract

The invention discloses a pull-joint type double-steel-plate composite shear wall, comprising steel pipe columns (steel pipe columns or concrete-filled steel tube columns) respectively arranged at the two ends, a pair of steel plates and at least one pull-joint type connecting piece. The pull-joint type connecting piece is firstly connected with the steel plates by staggered and intermittent one-side fillet welds in a welding way, and then a whole is assembled; the pull-joint type double-steel-plate composite shear wall has the advantages that the composite shear wall is simple in pull-joint structure, has a flat wall surface, and is less in welding workload, easy to operate and convenient to assemble; the stress performance of the composite shear wall is seldom affected by the welding quality since weld joints are positioned at construction parts; the composite shear wall is economical and safe; the steel plates and concrete are strong in cooperative work capability. A straight hook L shape, a sickle hook shape or hump hook shape can be adopted as the pull-joint way of the connecting piece, the pull-joint position can be positioned at the middle or side part of the thickness of the composite wall, and the pull-joint way is flexible and changeable, so that different engineering stress and use requirements are met. Riffled plates can be used as the wallboard steel plates and the pull-joint type connecting piece, so that the binding action between the wall steel plates and the concrete is effectively improved, and the co-working between steel components and the concrete is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a tie-type double steel plate combined shear wall. Background technique [0002] The double-steel composite shear wall has high bearing capacity, good ductility and stable hysteretic performance. Compared with the traditional concrete shear wall, it does not require formwork. The construction speed is fast and the wall is thin, which can effectively reduce the The structure is self-respecting. [0003] The double-steel composite shear walls that have been used at present generally include double-steel composite shear walls with tension bolts on both sides, double-steel composite shear walls with studs or T-shaped stiffeners on the inside of the wall panels, etc., such walls The thickness of the steel plate is relatively thick due to the way of tie, generally not less than 10mm, and the economy is poor. And the double-steel composite shear wall with tension bolts on ...

AI Technical Summary

Problems solved by technology

This kind of steel plate shear wall forms several cavities through welding connection of a large number of H-shaped, U-shaped, and T-shaped members. Because the weld seam is on the stress-bearing surface, and the thinner steel plate is easily affected by the welding temperature, there are disadvantages such as heavy welding workload, uneven wall surface, and mechanical performance controlled by welding performance.
