Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a steel structure connecting device. Background Art

[0002] Steel structure connection devices are key components in steel structure buildings, and their main function is to connect steel structure components into a whole.

[0003] There are many ways to connect steel structures, including but not limited to welding, bolting and riveting. Welding connections are usually used for rigid connections that can withstand bending moments, especially in structures that can withstand dynamic loads instead of directly bearing power, as well as in ultra-low temperature conditions. Bolted connections can generally be used, with quick on-site operation, convenient disassembly and maintenance. In existing steel structure connection technologies, the welding connection steps are relatively cumbersome during on-site construction of channel steel. After long-term use, when bolted connections are subjected to external vibrations, the bolts may become loose, resulting in abnormal wear or falling off of the bolts.

[0004] To this end, the utility model provides a steel structure connecting device. Utility Model Content
