With the development of the economic development and the vigorous development of civil engineering construction in China, particularly the gushing of super high-rise buildings and large-span buildings, the use of steel structural members is becoming more and more common. Due to limitations in processing capacity, allowable transport length, and lifting capacity, steel structural members need to be manufactured and transported in sections, and different sections of steel structural members are connected in the field.

At present, the field connection means of closed steel members such as rectangular steel pipes, round steel pipes, double-steel-plate shear walls and the like mainly comprise the steps of respectively welding lug plates outside upper and lower sections of steel members, and temporarily connecting the lug plates of the upper and lower sections of steel members by using mounting bolts through connecting plates. After the construction of the permanently spliced weld joint is finished, the mounting bolts and the connecting plate are disassembled, and the lug plates are removed. The traditional construction temporary connection mode can be seen from a national standard atlas of "detail of the construction of the steel structure node of the civil construction of multiple and high-rise" 16G519 ".
