Description

Technical Field

[0001] This utility model relates to the field of arch rib welding construction, specifically to an arch rib welding platform that is easy to install and dismantle. Background Technology

[0002] With the rapid development of highway construction, the application of long-span arch bridges is also increasing. For long-span reinforced concrete arch bridges, the construction height and span are becoming increasingly larger. The connection and welding of the rigid frame arch ribs presents challenges due to the high altitude, numerous points of contact, and significant safety risks. Currently, welding platforms are typically erected by assembly workers using steel sections and reinforcing bars after the arch ribs are connected. The platform is then removed after use. However, this method has the following problems: on-site installation and dismantling are difficult, inefficient, and time-consuming, impacting the overall construction period; the limited space for installation and dismantling, coupled with numerous welding and cutting processes, poses significant safety risks due to working at height; the platform is welded to the rigid frame arch ribs, reducing usable materials with each dismantling, making recycling uneconomical; and the direct welding of the platform to the rigid frame can easily damage it, making later repair difficult.
