Problems solved by technology

[0005] The purpose of the present invention is to provide a cold-formed thin-walled steel keel composite shear wall with steel skin to solve the problem that the cold-formed thin-walled steel wall in the prior art is prone to damage of the wall panel under the action of horizontal load, resulting in splintering. The problem of screw failure at the seam

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The cold-formed thin-walled steel keel composite shear wall of the present invention is mainly composed of a cold-formed thin-walled steel keel skeleton and wall panels. Such as figure 1 As shown, the cold-formed thin-walled steel keel skeleton is formed by the cold-formed thin-walled steel keel column 1 , the cold-formed thin-walled steel upper guide rail 2 and the lower guide rail 3 connected to each other by self-tapping screws 4 . Cold-formed thin-walled steel keel column 1 can choose single C-section column or back-to-back double C-section column according to the load level; the distance between keel columns is generally 600mm or 400mm. Then install a layer of base wall panels on both sides of the keel frame (such as figure 2 As shown), the size of the wall panel 5 is generally 3000mm×1200mm×12mm, the direction of the long side o...

Abstract

The invention discloses a cold-bent thin-walled steel-keel combined shear wall with steel skin, comprising a cold-bent thin-walled steel-keel framework and wall panels on two sides of the keel framework. The wall panels on the same side of the cold-bent thin-walled steel-keel framework include at least two layers, the steel skin as high as the wall panels is fixedly clamped between the adjacent layers of wall panels. The wall panels, the steel skin and the cold-bent thin-walled steel-keel framework are interconnected through penetrating of tapping screws. By adding the layer of steel skin, lateral capacity and rigidity of the wall are improved; compared with existing walls, the wall is added with building panels, has significant improvement in thermal insulation, acoustic insulation and fire proofing and is free of cold bridge effect.

Description

technical field [0001] The invention relates to a cold-formed thin-wall steel keel composite shear wall with a steel skin, belonging to the technical field of civil engineering. Background technique [0002] Compared with the traditional reinforced concrete structure, the steel structure has the characteristics of green environmental protection, good seismic performance, fast construction speed, and recyclable materials. With the rapid development of the national economy, my country's steel output has leapt to the first place in the world, and the domestic steel structure industry has also developed rapidly. However, compared with developed countries, the proportion of steel structure buildings in my country's steel production is still significantly low. Significant gaps still exist. my country is in the stage of rapid industrialization and urbanization, the annual project construction volume is huge, the resource consumption is serious, and the pressure of environmental de...
