[0002] Prefabricated steel structure buildings are developing rapidly in the construction industry with the advantages of being green and environmentally friendly, excellent quality, good earthquake resistance, and easy construction. Among them, steel circular tube columns are widely used in high-rise and super-high-rise buildings due to their special structural properties. Steel circular tube columns are mainly composed of columns, inner partitions and corbels. The installation progress of circular tube columns mainly depends on the processing progress of circular tube columns. The assembly and welding speed of the inner partitions corresponding to the corbels directly affects the processing efficiency of circular tube columns.

[0003] For the welding of partitions inside circular tubes with larger diameters, welders can perform welding inside the circular tubes if there is enough operating space inside. However, for circular tubes with smaller diameters, welders must drill into the circular tubes for welding. The internal space is small, and this situation not only limits the working space and poor working environment, but also obstructs the welder's line of sight, affecting the welding quality. This not only endangers the health of workers, but also makes it difficult to ensure the quality of components. Utility Model Content
