[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation. Therefore, it is particularly suitable for building large-span, ultra-high, and ultra-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can have large deformation, can withstand dynamic loads well, has a short construction period, and has a high degree of industrialization.

The multiple parts of the steel structure columns are very troublesome to transport and occupy a large area. They are also very troublesome to splice. Workers need to fix the multiple parts of the steel structure columns together through fixed structures, which increases the workload. Utility Model Content
