Description

Technical Field

[0001] This invention relates to the field of bridge assembly platform technology, specifically to a steel bridge assembly platform structure and its usage method. Background Technology

[0002] A steel bridge assembly platform is an important facility used in bridge construction, primarily for the assembly and installation of bridge components. The structure of a steel bridge assembly platform includes: Main load-bearing structure: typically composed of steel beams and columns, providing the main load-bearing capacity. These structural components usually use high-strength steel to withstand significant loads and stresses. Support system: includes temporary and permanent supports. Temporary supports are used during construction, while permanent supports are an integral part of the bridge structure. Connectors: connection methods such as bolts and welding are used to connect the various steel structural components. These connection points are critical parts of the entire structure. Working platform: provides working space for workers and typically includes guardrails and safety nets to ensure construction safety. Lifting equipment: used to lift bridge components such as beams, slabs, and box girders to designated locations.

[0003] When applying for this invention, the applicant, after searching, discovered a Chinese patent disclosing a "steel structure bridge assembly platform structure and its usage method," application number "CN202310317576.X." This patent mainly uses the vertical support movement of the main hoisting mechanism to raise the support section from bottom to top, without the need for hoisting equipment; the four outriggers can provide stable support for the equipment and arch ribs; the connecting support group and the fixed support group can form a fan-shaped support structure, which not only supports the connecting section and the fixed section, but also improves assembly efficiency. However, this device is not conducive to lifting and lowering during use, especially after installation on the upper side of the bridge, making disassembly difficult. Therefore, based on the applicant's invention, a steel structure bridge assembly platform structure has been invented, which solves the problem of easy lifting and lowering during use and avoids the inability to effectively change the height.
