The structure of single standard festival includes four round bars 300 that the equipartition set up, connects fixedly through a plurality of connection frames 301 between the round bar 300, and connects fixedly through diagonal brace 302 between two adjacent connection frames 301, wherein, can improve the stability of connecting between the connection frames 301 through diagonal brace 302. The connecting frame 301 is assembled by welding four angle irons. While the round bar 300 is referred to herein as a hollow structure for convenience in performing the butt joint operation between the standard knots. When assembling and welding single standard joint, it is currently adopted to place two of the round bars 300 in parallel on a workbench, then weld the connecting frame 301 between the two round bars 300 one by one, after the welding is completed, the operator welds the other two round bars 300 on the upper end of the connecting frame 301, and finally performs the welding operation between the diagonal brace 302 and the connecting frame 301.

When the prior art is adopted to perform assembly welding of a single standard joint, because the round bars 300 are not positioned, an included angle is easy to exist between the round bars 300 in the welding process, meanwhile, when the round bars 300 positioned at the upper end are welded, the round plates 300 need to be lifted through lifting equipment such as a portal frame, and in the welding process, due to the adoption of the mode, the phenomenon of displacement of the round bars 300 is easy to occur, so that the accuracy of the welded standard joint is influenced, and the connection operation of the standard joint is further influenced.
