[0002] The corner of a transmission tower mainly includes a base plate a and a vertical plate b welded on the base plate a. As the owner requires full penetration of the tower corner, the existing assembly tooling of the manufacturing company can no longer fully meet the quality system requirements. Usually, when the base plate a and the vertical plate b are assembled, the manufacturer uses the welding wire head to reserve a gap.

Process measures such as patching must be taken, which not only affects the performance and organization of the steel, but also increases the production cost and delays the processing period. Therefore, it is necessary to design a transmission tower corner gap fixing device that ensures the joint gap during welding and improves the assembly efficiency to improve the above problems.
