An assembled steel structure tower drum connecting joint

Abstract

The application discloses an assembled steel structure tower drum connecting joint and belongs to the technical field of assembled tower drums. The steel structure tower drum comprises an upper drum body and a lower drum body. The inner side of the upper drum body is fixed with an annular support. A tapered cavity with a large upper part and a small lower part is formed in the center of the annular support. A pre-tightening pressing table is arranged in the tapered cavity. A clamping limiting plate is connected to the upper connecting joint through an elastic supporting device. The clamping limiting plate partially extends out of the sliding hole in the radial direction under the action of the pre-supporting force of the elastic supporting device. When the annular support moves upward relative to the pre-tightening pressing table, the pre-tightening pressing table contacts the clamping limiting plate on the inner wall of the tapered cavity and drives the displacement of the clamping limiting plate. The lower end of the clamping limiting plate can be clamped in the clamping groove. The device only needs to pre-tighten the pre-tightening pressing table and the lower connecting joint to realize the quick connection between the upper drum body and the lower drum body, and does not need to consider the assembly inconvenience caused by the numerous and complex connecting structures.
