[0002] In the construction of modern steel structure buildings, the precise installation of steel beams directly determines the stability of the main structure of the building and the safety of construction. The installation of steel beams requires the use of temporary support devices for positioning and adjustment. Traditional support devices mostly use fixed brackets with hydraulic jacks. This type of device has gradually exposed many technical bottlenecks in actual applications.

[0003] Existing support devices mostly use a rigid bracket structure with a fixed spacing. The adjustment of the support spacing usually requires overall disassembly and reorganization, which has low operating efficiency. In addition, when adjusting the height of the steel beam, multiple jacks are required to operate in coordination, and the synchronization accuracy is poor, which can easily cause deformation of the steel structure and may cause chain deviations in subsequent installation processes. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content
