Plug welding type double-steel plate composite shear wall

Abstract

The invention discloses a plug-welded double-steel plate combined shear wall, which comprises a steel pipe column (steel pipe column, steel pipe concrete column) located at both ends, a pair of steel plates and a plug-welded connector, and the two steel plates are plug-welded The knot of the type connector forms a whole. The plug-welded double steel plate composite shear wall has flat wall surface, less welding workload, the weld is located in the structural part, the mechanical performance of the shear wall is less affected by the quality of the weld, economical and safe, and the steel plate and concrete have a strong ability to work together, etc. advantage. The cross-section of the plug-welded connector is [-shaped or Z-shaped, and the ends of the [-shaped and Z-shaped connectors can be folded inward, and holes can also be arranged on the web of the connector to ensure the overall work of concrete and steel plates. and the compactness of concrete pouring. The wall plate steel plate and tie connectors can use checkered steel plates, which can effectively increase the bonding effect between the wall steel plate and concrete, and ensure the joint work between steel components and concrete.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a plug-welded double-steel plate composite shear wall. Background technique [0002] The double steel plate composite shear wall has high bearing capacity, good ductility and stable hysteretic performance. Compared with the traditional concrete shear wall, it does not need formwork, the construction speed is fast, and the wall is thin, which can effectively reduce the cost to a certain extent. Structural weight. [0003] The double-steel plate composite shear walls that have been used generally include double-steel plate composite shear walls with tension bolts on both sides, and double-steel plate composite shear walls with studs or T-shaped stiffeners on the inner side of the wall panels. Due to the tie method, the thickness of the steel plate is thick, generally not less than 10mm, and the economy is poor. In addition, the double-steel composite shear wall with t...

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.
