Super-long steel structure C-shaped purlin anti-deformation combination structure

Abstract

The invention relates to a super-long steel structure C-shaped purlin anti-deformation combination structure. The combination structure comprises a steel structure C-shaped purlin and an L-shaped angle iron, the steel structure C-shaped purlin comprises a top flange, a web and a bottom flange, and the L-shaped angle iron comprises a first angle iron right-angle flanging and a second angle iron right-angle flanging; several corresponding bolt apertures are arranged at the web and the first angle iron right-angle flanging; the L-shaped angle iron and the steel structure C-shaped purlin are fixedly connected through the bolt and nut of the bolt aperture; and the bottom of the second angle iron right-angle flanging and the bottom of the bottom flange are aligned and positioned at the same plane. The bottom flange of the super-long steel structure C-shaped purlin and the L-shaped angle iron are combined and connected to form a T-shaped cross section, the bottom flange edge of super-long steel structure C-shaped purlin is effectively protected, and distortion and deformation due to over long steel structure C-shaped purlin while hoisting and installing can be prevented.

Description

technical field [0001] The invention belongs to the technical field of metal building components, and in particular relates to an anti-deformation composite structure of C-shaped purlins in an ultra-long steel structure. Background technique [0002] The application of steel structures in my country began in the early 1980s. After nearly 20 years of rapid development, steel structures have become more and more widely used in modern industrial buildings and large-span public buildings. Steel structure buildings are mainly used in industrial plants, warehouses, gymnasiums, exhibition halls, mobile houses, and extra-story buildings, etc. Especially in the application of industrial plants, it has many advantages such as light weight, environmental protection, energy saving, high efficiency, high degree of industrialization, and convenient construction. advantage. At present, there are many domestic waste incineration plant construction projects every year, and steel structure c...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the excessive distance between the walls of domestic waste incineration power generation projects and logistics warehouses, etc., leads to the excessive length of C-shaped purlins in steel structures, which is easy to cause distortion and deformation at the edge of the lower flange during lifting and installation. Problem, the present invention provides an anti-deformation combined structure of C-shaped purlins in super-long steel structure
