Description

[0002] The type steel concrete column and the type steel concrete beam refer to prefabricated columns and prefabricated beams which are prefabricated by pouring concrete into a type steel as a main built-in metal skeleton. Compared with cast-in-situ columns and beams, the prefabricated beams and the prefabricated columns need to be subsequently connected, and therefore the connection joint position of the beam-column connection is a key and weak position in the building structure. In order to improve the strength and stability of the joint position as much as possible, the joint position of the prefabricated beam and the prefabricated column is often fixed by steel bars or connected by type steel welding during construction. The connection structure is basically rigid connection, and internal force concentration is easy to occur at the joint position. When the beam-column structure is stressed, the force is transmitted between the connection structures.
