Problems solved by technology
[0005] The purpose of the present invention is to provide a cold-formed thin-walled steel composite wall that is resistant to continuous collapse and a rapid on-site installation method to solve the problem of the planar layout of the floor beams caused by the failure of the upper guide rail in the prior art to effectively vertically transmit the composite wall The form is limited by the plane position of the column in the wall. At the same time, the failure of a column in the wall may cause the continuous collapse of the entire wall.

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] The invention relates to a cold-formed thin-walled steel composite wall resistant to continuous collapse, which includes a combined upper guide rail, a lower guide rail, wall columns and wall panels; the combined upper guide rail is composed of a conventional U-shaped cold-formed thin-walled steel keel, web The ribbed U-shaped cold-formed thin-walled steel keel and the outer frame U-shaped cold-formed thin-walled steel keel can transmit the vertical load inside the wall. in:
[0031] Conventional U-shaped cold-formed thin-walled steel keel (hereinafter referred to as U-shaped keel / conventional U-shaped keel) is a component commonly used in the prior art as the guide rail of the upper / lower wall column of the cold-formed steel composite wall. In the prior art, it is fixedly connected with the flange of the C-shaped keel column at equal intervals ...

The invention discloses a progressive collapse resistant cold-formed thin-walled profile combined wall and quick field mounting method thereof. An upper guide rail is a combined guide rail composed of a conventional U-shaped cold-formed thin-walled steel keel, a ribbed web U-shaped cold-formed thin-walled steel keel and an outer-framing U-shaped cold-formed thin-walled steel keel. A lower guide rail is a conventional U-shaped cold-formed thin-walled steel keel. A wall pillar is a C-shaped cold-formed thin-walled steel keel. The upper guide rail can effectively transmit vertical load, thus a cold-formed thin-walled steel floor beam need not be aligned with the keel pillars of the combined wall, and flexibility of a structural arrangement scheme of a cold-formed thin-walled steel house is improved; meanwhile, when the certain keel pillar of the combined wall is destructed due to earthquake, fire or the like, the upper load of the pillars can still be transmitted to the other wall pillars through the upper guide rail, progressive collapse of the combined wall is avoided, and structural safety and reliability is improved.
Description
technical field [0001] The invention relates to a continuous collapse-resistant cold-formed thin-walled steel composite wall, which belongs 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 environme...
