Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a steel structure truss initial installation positioning device. Background Art

[0002] With the development of science and technology and the increasing demand for building safety, economy, and aesthetics, the demand for large-span buildings continues to increase. The conventional method for the hoisting and construction of large-span steel structures is to pre-process them in the factory and then assemble them at a high altitude. After the first truss is hoisted to the designated location, the truss is initially welded to the column top support to prevent lateral bending caused by strong winds and collisions. The position must be precisely controlled during the initial welding. Traditional methods such as pulling cables and setting up stabilizing cranes either require strict site requirements or increase construction costs significantly. In particular, when the diameter of the bottom column is larger than the truss steel section, ordinary positioning methods cannot be used. Therefore, it is necessary to develop a new technology that is less demanding on the site and can significantly save construction costs to fill this gap. Utility Model Content
