[0002] Cross-section steel columns in building steel structures are increasingly used in steel structure projects due to their good bidirectional stress performance, high stability, and strong rigidity, especially in steel-concrete structural columns of high-rise steel structures.

[0003] The cross column is composed of an H-shaped steel and two T-shaped steels. Since the main materials of the cross column are thick plates and the component penetration is large, the assembly accuracy of the H-shaped steel and the T-shaped steel is rough when the cross-shaped steel column is welded and assembled. In addition, the butt welding of the thick plates of the cross column and the existence of overall shrinkage stress cause the cross-shaped steel column to deform greatly during welding, and the deformation correction is more difficult, which affects the welding accuracy of the cross-shaped steel column and reduces the production quality of the cross-shaped steel column. Therefore, in view of this, the inventor provides a welding frame for a cross-shaped steel column to solve the above problems. Utility Model Content
