Meanwhile, the assembly type construction method is advocated, and the technical difficulty of the assembly type steel structure building is mainly concentrated on the beam column connecting nodes.

In the prior art, beam column rigid connection nodes of a steel structure mainly have the following three connection modes: 1. the upper flange and the lower flange are connected by full penetration weld joints, and the web plates are connected by high-strength bolts, namely, bolt welding and mixed connection; 2. the flanges and the web are all welded, namely all welded; 3. the upper flange and the lower flange are connected with the web plate by high-strength bolts, namely, all-bolts are connected.

The beam upper flange and the beam lower flange are in full penetration connection, and the beam upper flange and the beam lower flange are required to be installed and welded in construction, so that the construction progress is longer, and the quality of welding seams is difficult to guarantee due to high-altitude operation. In the third connection mode, since the assembled steel frame generally needs to be assembled on the transportation site after the prefabrication of the components is completed, the assembly is limited in terms of manufacturing process, transportation capability and construction cost, and the length of the column components in the multi-layer and high-layer steel frame generally cannot meet the requirements, the assembly is needed, and the assembly can lead to the occurrence of stress concentration and generate weak parts, so that the stress performance of the structure is affected.
