Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for steel structure construction, and particularly to an auxiliary device for assembling and welding large steel structure trusses. Background Art

[0002] During the construction of large steel structures, the assembly and welding of steel trusses are extremely crucial core links, and their quality directly affects the stability and safety of the entire building structure. Currently, the traditional assembly and welding work of large steel structure trusses is facing many severe challenges. In terms of positioning, when the existing auxiliary devices position the steel trusses, their accuracy is far from meeting the increasingly high engineering quality requirements. In actual operations, workers often can only rely on simple measuring tools such as tape measures and spirit levels, combined with their accumulated manual experience, to roughly determine the welding positions. This crude positioning method has great uncertainties and is likely to cause varying degrees of deviation after the steel trusses are welded. Even extremely slight deviations, after accumulating layer by layer in large building structures, may have an inestimable negative impact on the stability and safety of the overall structure.

[0003] During the process of supporting and lifting the steel trusses, the existing equipment also exposes obvious defects, and its support stability is poor. During the operation, due to problems such as the structural design or material strength of the equipment itself, it is extremely prone to shaking or displacement. For example, some common simple jack support devices at the construction site will shake slightly when bearing the huge weight of the steel trusses, resulting in position changes of the steel trusses during the assembly and welding process. This not only greatly increases the construction difficulty for the construction workers to reposition and adjust the steel trusses, prolongs the construction time, but also is very likely to cause defects in the welds due to position changes, thereby reducing the welding quality.
