Description

TECHNICAL FIELD

[0001] The utility model relates to a novel double-spliced C-shaped steel structure and belongs to the technical field of building steel structures. BACKGROUND

[0002] C-shaped steel is a kind of material commonly used in steel structure buildings, and when the structural bearing capacity requirement is high, the double-spliced C-shaped steel may be used. The conventional double-C-shaped steel is welded by using mixed gas shielded welding or carbon dioxide gas shielded welding, and the welding seam is required to be free of pores, free of missed welding, neat and beautiful, and the strength meets the relevant requirements of the state.

[0003] In addition, in the existing welding technology, when the length of the double-spliced C-shaped steel is relatively long, especially when the length of the double-C-shaped steel is up to 6 meters, welding deformation may be caused after full welding of the double-face straight seam. When welding the other side after removing the clamps for adjusting the position of the first side, the workpiece is difficult to be installed on the tooling due to the large deformation, and the original mechanical clamping device hinders the straight-line movement of the welding gun. During the welding process, the clamping device needs to be manually removed to allow the welding gun to pass through. Removing the clamping device may cause the workpiece to shift, and the welding quality is difficult to guarantee. The positioning and welding process is also very complex, and the manual efficiency is low.

[0004] Based on this, the utility model is proposed. CONTENT OF THE UTILITY MODEL
