[0002] Beams and columns are commonly used components in steel structure buildings, and they play different roles. Steel columns are vertical force-bearing components, which mainly bear the weight and vertical load of the building and transfer them to the foundation. Steel columns have high strength and rigidity, which can meet the load-bearing requirements of buildings. Steel beams are transverse force-bearing components, which mainly bear the horizontal loads of buildings, such as wind loads, earthquake loads, etc. Steel beams have high bending and shear strengths, which can meet the lateral stability requirements of buildings. At present, steel beams and steel columns are mainly welded by steel plates, and the welding methods include manual and mechanical. In the process of performing steel plate butt welds, after completing the welding of a butt joint, steel plates need to be added for butt welding multiple times. This method causes frequent repeated operation of mechanical equipment, which is complicated and reduces the production welding efficiency of steel beams and columns. To this end, the utility model proposes a steel structure beam and column welding auxiliary fixture, which is convenient for manual or mechanical automatic welding and improves the welding efficiency of steel beams or steel columns.
