[0002] Prefabricated structure is the abbreviation of prefabricated concrete structure. It is a concrete structure that is assembled and connected with prefabricated components as the main load-bearing components. Prefabricated reinforced concrete structure is one of the important directions of development of my country's building structure. It is conducive to the development of my country's building industrialization. Among them, prefabricated prefabricated steel beams are widely used in my country's construction industry. When prefabricated steel beams are installed, they often need to be equipped with steel structure node connection structures to support the installation of the steel beams.

[0003] At present, the prefabricated steel beam node connectors are generally connected to the prefabricated beam column through a simple connecting plate through chemical anchor bolts, and the steel beam and the connecting plate are directly welded. The above connection method has certain shortcomings. The steel beam and the prefabricated beam column are rigidly connected. The bending deformation of the steel beam after loading is subject to a certain pressure and transmitted to the prefabricated beam column. The prefabricated beam column will produce bending deformation, thereby causing damage to the prefabricated beam column, which is not convenient for the safe and stable use of the prefabricated beam column. For this reason, we propose a prefabricated beam-column steel structure node with stable connection to solve the above problems. Utility Model Content
