Problems solved by technology
[0005] The object of the present invention is to provide a cold-formed thin-walled steel combined upper guide rail capable of transmitting vertical loads, so as to solve the problem that the combined wall body in the prior art cannot effectively transmit and damage the floor beams and floor panels above the wall columns due to the failure of the upper guide rails. Vertical load, resulting in the failure of a wall column and the continuous collapse of the entire wall

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] The invention relates to a combined upper guide rail of cold-formed thin-walled steel. The upper guide rail is composed of a conventional U-shaped cold-formed thin-walled steel keel, a U-shaped cold-formed thin-walled steel keel with ribs on the web, and a U-shaped cold-formed thin-walled steel frame. Composed of keels, it can transfer the vertical load inside the wall. in:
[0021] 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 to form a light steel skeleton.
[0022] Web ribbed U-shaped cold-formed thin-walled steel keel (herei...

The invention discloses a cold-formed thin-walled section steel combined guide rail capable of transferring vertical load, comprising a conventional U-shaped cold-formed thin-walled section steel keel, a web ribbed U-shaped cold-formed thin-walled section steel keel and an outer frame U-shaped cold-formed thin-walled section steel keel. The web ribbed U-shaped cold-formed thin-walled section steel keel and the conventional U-shaped cold-formed thin-walled section steel keel are both located in space formed by the outer frame U-shaped cold-formed thin-walled section steel keel and flanges; the web ribbed U-shaped cold-formed thin-walled section steel keel is disposed between the outer frame U-shaped cold-formed thin-walled section steel keel and the conventional U-shaped cold-formed thin-walled section steel keel; the flanges of the keels are in fixed connection; webs of the keels are fixedly connected via bolts. The cold-formed thin-walled section steel combined guide rail is simple in structure, reliably connectable and high in construction speed; by the use of the cold-formed thin-walled section steel combined guide rail in a bearing wall system in a cold-formed thin-walled section steel housing building system, the vertical load of a floor can be effectively transmitted to wall columns, the flexibility of a floor beam structural arrangement scheme is improved, and a bearing wall is better in safety and reliability.
Description
technical field [0001] The invention relates to a cold-formed thin-wall steel combined upper guide rail capable of transmitting vertical loads, and 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 press...
