[0002] Truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. The rods mainly bear tension or pressure, which can give full play to the role of the material, save materials and reduce the weight of the structure. Commonly used ones are steel trusses, reinforced concrete trusses, wooden trusses, steel-wood composite trusses and steel-concrete composite trusses. The existing truss structure rod docking mainly adopts welding connection or flange bolt connection. The on-site welding construction requires more resources and measures, which is troublesome and easy to misalign, and the precision control is difficult.

[0003] The connection of the space steel trusses of stadium stands, parking lots, etc. is usually welded.
