[0002] With the continuous rise of the refined steel industry and the continuous improvement of the process level, the expression of refined steel has also been widely used. Due to the special requirements of the glass curtain wall system, a telescopic structure must be set between the steel beams and steel columns (that is, both ends cannot be welded and fixed). One end is usually threaded with an adapter and the other end is directly welded and fixed. However, welding will damage the surface of the refined steel and is not easy to repair. This premise has caused the complexity of the connection design between the steel beams and steel columns of the glass curtain wall.

[0003] To adapt to this complexity, the current solution is to fix two U-shaped steel parts on both sides of the steel column with bolts, and install and fix a steel beam through a U-shaped steel part during installation. However, this method has low installation efficiency and is time-consuming and labor-intensive. Utility Model Content

[0031] By welding a connector 3 on the steel column 1, which can be used to connect the steel beams 2 on both sides, the problem of complex connection between the existing curtain wall steel beams 2 and the steel column 1 and time-consuming and labor-intensive installation is solved. At the same time, the connector 3 and the steel beam 2 are threadedly connected, avoiding the surface damage and unsightly appearance caused by welding.
