Description

Technical Field

[0001] This utility model relates to the field of arch bridge construction, specifically to an adjustable-angle arch rib welding platform. Background Technology

[0002] The rigid framework of arch bridges possesses high load-bearing capacity and stability, capable of withstanding various loads during construction and ensuring the safety and quality of arch bridge construction. During the hoisting process, the connection between arch rib segments is typically achieved through welding, requiring assembly workers to erect welding platforms on-site using materials such as structural steel and reinforcing bars. However, this method of erecting welding platforms presents several problems: as the arch rib installation progresses, the slope of the arch rib changes, causing the height of the welding platform for each arch rib segment to change. Using on-site measured angle data for processing results in low construction efficiency and a long construction period, impacting the overall progress of arch rib installation; furthermore, the working space at the arch rib joints is relatively narrow, and the construction process involves numerous welding and cutting procedures, posing significant safety risks.
