Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an elevated bridge column wall-attached self-climbing operating platform and a method. Background Art

[0002] In the process of urban renewal and development, the number of projects to elevate and renovate existing urban expressway networks has been increasing. In recent years, the full prefabrication and assembly of urban elevated bridges has developed rapidly. By adopting full prefabrication and assembly technology for the pile foundation, piers, columns, cap beams, box beams and other structures of elevated bridges, significant improvements in quality and efficiency can be achieved.

[0003] During the prefabrication and assembly of urban elevated bridges, there are construction operations such as hoisting positioning and sleeve grouting connection during the assembly of large-scale super-high columns and column-cap beams, which require construction personnel to arrive at the assembly location for auxiliary construction. If all the manual operations are done by traditional aerial platforms, it will be extremely dangerous. If the site is leveled around the column and temporary scaffolding is built, it is extremely time-consuming, labor-intensive, and space-consuming compared to the entire positioning, installation, and connection operations, which is extremely unfavorable for efficient and rapid construction; at present, the more popular practice is to preset a clamp-fixed operating platform at the predetermined height of the column, and use a aerial platform to realize the operation of personnel on the platform. However, this approach is still applicable to the one-time column-cap beam assembly construction, while for multi-stage construction such as super-high segmented column installation and column-cap beam assembly construction, it is necessary to adjust the height of the operating platform many times and repeatedly disassemble and assemble it, which greatly wastes working hours and especially reduces the efficiency of the nodes.

[0004] Therefore, how to provide a self-climbing operating platform attached to the wall of an elevated bridge column to solve the problem of insufficient work efficiency caused by repeated disassembly and assembly of conventional operating platforms during the assembly construction of standard sections of columns and between standard sections of columns and cap beams is a technical problem that technical personnel in this field urgently need to solve.

By adopting multiple sets of adaptive wall-attached devices, active adaptive adjustment of the cross-sectional dimensions of different standard sections of columns is achieved; by adopting multiple sets of alternating wall-attached self-climbing power devices, the overall cyclic alternating lifting of the operation platform is achieved, so that the operation platform can be installed as a whole once and flexibly positioned multiple times during the entire installation and construction process; by using a self-locking device, one-way travel locking is achieved during the climbing process, ensuring the climbing anti-skid and anti-falling safety of the operation platform; and a high-efficiency, low-impact operation platform solution is provided for the assembly and construction between standard sections of super-high columns of elevated bridges, and between standard sections of columns and cap beams.
