Rustless efficient fabricated building steel cross beam in steel frame structure factory building and bearing column thereof

Abstract

The invention discloses a rustless efficient fabricated building steel cross beam in a steel frame structure factory building and a bearing column thereof. The rustless efficient fabricated building steel cross beam comprises a bearing mechanism, a manufacturing mechanism, a cross beam bridging mechanism, a sealing mechanism and an airflow dredging mechanism, wherein the bearing mechanism comprises a pressing part and an auxiliary fixing part, and the pressing part comprises a steel frame shell, a screw rod and a pressing block, wherein the screw rod and the pressing block are connected into the steel frame shell. According to the rustless efficient fabricated building steel cross beam, the screw rod and the pressing block are movably arranged in the steel frame shell, and a limiting combination and a base are arranged at the bottom end of the steel frame shell; and during use, a concrete vertical pile is inserted into an inner cavity of the steel frame shell in a matched mode through a prefabricated part, the concrete vertical pile is inserted into the steel frame shell, the pressing block is controlled by adjusting the screw rod to integrally fix and clamp the steel frame shell on the outer side of the concrete vertical pile, meanwhile, the base is arranged at the root of the concrete vertical pile, so that the inner wall of the steel structure bearing column can be prevented from being damaged, and then the corrosion of external factors to a metal layer of the device is avoided.

Description

technical field [0001] The invention relates to the field of building steel structures, in particular to a rust-free and high-efficiency assembled building steel beam and its load-bearing column in a steel frame structure factory building. Background technique [0002] Steel structure building is a new type of building system. It breaks through the industry boundaries between the real estate industry, construction industry, and metallurgy industry, and integrates them into a new industrial system. Compared with traditional concrete buildings, steel structure buildings use steel plates or section steel Instead of reinforced concrete, it has higher strength and better earthquake resistance, and the components can be manufactured in a factory and installed on site, so the construction period is greatly reduced. Due to the reusable steel, the generation of construction waste can be greatly reduced. [0003] Nowadays, the steel structure building technology is gradually becoming ...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, the steel structure building technology is gradually becoming mature, but each component of the steel structure building is made of metal. When the protective film on the surface of the steel structure component is worn, it is affected by various external factors and loses the protection of the protective film. , Steel structure components are prone to corrosion. In order to improve the durability of the main body of the steel structure building and the stability of the load-bearing column of the steel structure, it is more and more important for people to improve the protection of the inner wall of the load-bearing column of the steel structure building.
