The components or parts are usually connected by welds, bolts or rivets. It is widely used in large factories, venues, super high-rise buildings, bridges and other fields;

[0003] In the field of building steel structures, the installation of connection nodes is an important guarantee for the stability and safety of the entire structure. At present, the building steel structure connection nodes widely used in the market mainly rely on traditional methods such as welding and bolting. However, these traditional methods have many inconveniences during the installation process. First, although the welding connection has high strength, it requires professional skills and equipment, and the welding time is long. For large steel structures, the installation efficiency is low. Secondly, although the bolt connection is simple to construct and easy to disassemble and assemble, it requires a large number of bolts, which increases the material consumption cost, and for structures with complex shapes, the installation is difficult. Therefore, it is necessary to develop a new type of building steel structure connection node that is easy to install quickly to improve installation efficiency and reduce construction costs.
