Description

Technical Field

[0001] The utility model relates to welding auxiliary equipment, in particular to a welding device for producing steel structure engineering columns and beams, which is used for assisting the welding positioning of columns and beams and column-beam connecting plates. Background Art

[0002] The connection between beams and columns in steel frames plays the role of transferring bending moment and shear force between the two components. It is the main component of the steel frame, and its performance is directly related to the overall response of the structure. The design of beam-column connection should meet sufficient strength and appropriate rigidity, and meet the principles of "strong nodes, weak components" and "strong beams and weak columns". The beam-column connection of steel frame structures is mostly designed as a rigid connection, and the connection between the main beam and the column has sufficient rigidity. At present, the lateral force resistance frame and the bending resistance connection of beams and columns all adopt rigid solutions. The rigid connection of beams and columns is mainly achieved by welding.

[0003] At present, there are many devices that can be used for welding steel structure columns and beams in the prior art, for example: Chinese patent CN118143493A discloses a steel structure engineering column and beam welding device. However, the column and beam welding device is only suitable for positioning and welding steel plates to form H-shaped steel column and beam workpieces, and the column and beam assembly process often requires the column and beam to be vertically welded to form a T-shaped structure, and then assembled.
