Description

Technical Field

[0001] The utility model relates to the technical field of steel structure truss construction, in particular to an adjustable large cantilevered circular tube truss and a temporary support connecting device. Background Art

[0002] A circular tube truss is a lattice structure composed of circular rods (tubes) connected at their ends. The rods in a truss are mostly subjected only to axial tension or compression, resulting in evenly distributed stress across the cross section, effectively maximizing the material's performance. These characteristics make truss structures economical in material use, lightweight, and easily adaptable to various configurations, such as simply supported trusses, arches, frames, and towers.

[0003] During the actual construction of a large cantilevered circular tube truss, due to the large cantilever length of the truss rods, a supporting structure is required to temporarily support it to prevent it from deflecting or bending. However, the existing large cantilevered circular tube truss and temporary support connection device cannot adjust its height during actual use, and the positioning plate cannot be replaced according to the diameter of the circular tube. It has great limitations in use. To address this problem, an adjustable large cantilevered circular tube truss and temporary support connection device is provided. Utility Model Content
