Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary support devices for welding steel structure space frames, specifically an auxiliary support device for welding steel structure space frames. Background Technology

[0002] Steel space frame structures are a common roofing form used in large stadiums, industrial plants, theaters, waiting halls, and other buildings in China. This new structural method relies on the inherent strength of the steel structure itself, using bolts to connect individual steel columns, creating an interlocking network of roof spaces of various shapes and sizes. The free-flowing and elegant form of steel space frame structures encompasses both the rhythmic beauty of classical architecture and the romanticism of modern art, offering advantages such as good structural integrity, convenient installation, and excellent seismic performance.

[0003] However, it still has some drawbacks. For example, long steel pipes are often used when welding steel structure space frames. When welding these long steel pipes, people need to manually hold the long steel pipes to carry out the welding, which is not only troublesome but also easy to weld poorly.

[0004] To address the aforementioned issues, this application proposes an auxiliary support device for welding steel space frames. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a lifting mechanism powered by hydraulic pressure.
