[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Steel structures are prone to rust. Generally, steel structures need to be rusted, galvanized or painted, and maintained regularly. Among them, personnel may need to use spherical node welding, and spherical node welding refers to the welding of hollow spherical nodes. Hollow spheres are welded from two hemispheres. Hollow spheres without ribs and hollow spheres with ribs can be used according to the force size. In order to ensure that the angle between the steel pipe and the spherical node in the steel structure is maintained, personnel can choose to use auxiliary devices to support and limit the spherical node and the steel pipe.

[0003] In the actual process of personnel using the auxiliary device, affected by the size relationship between the spherical component and the component steel pipe, if the personnel need to spend a long time to adjust the auxiliary support device, it may cause the personnel's fatigue to increase rapidly, which will greatly affect the personnel's work efficiency and provide limited convenience for the personnel. Therefore, an auxiliary device for spherical node welding for building steel structures is proposed. Utility Model Content
