Description

Technical Field

[0001] The present invention relates to the technical field of steel trusses, and particularly to a steel truss unit assembly jig. Background Art

[0002] In the field of steel structure construction technology, especially for large steel structure exhibition halls, stadiums and other projects, the truss unit assembly construction process is often adopted, and the steel structure trusses are often assembled and welded in the construction site area;

[0003] When assembling large special-shaped structure trusses on site, due to the large self-weight of the overall steel structure members and the non-uniform height of each member, the adjustable-height jigs often have stiffness that fails to achieve the expected effect. The assembly jigs are all completed by the method of bolts cooperating with fastening nuts. Since the steel structure construction requires matrix assembly of multiple jigs, the assembly workload is greatly increased, and the traditional connection method will seriously affect the assembly efficiency.
