Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a connection and fixing structure of a cantilevered main beam and a connecting beam. Background Art

[0002] Cantilever structure is a common structural form in building construction. In cantilever structure, the cantilever main beam bears the main load, and the installation stability of the cantilever main beam determines the stability of the cantilever structure. Cantilever structure often requires the use of connecting beams. At present, the connection between the cantilever I-beam main beam and the connecting beam is often welded or U-shaped steel connection. The welding operation is cumbersome. During welding, the power supply must be guaranteed. The working surface is narrow and the construction is difficult. It is easy to damage the I-beam during the later dismantling, which reduces the structural strength of the I-beam, resulting in a decrease in the number of turnovers and structural safety of the I-beam. The U-shaped steel connection method has problems such as loose connection and easy sliding. Utility Model Content
