Scattered part type cantilever assembly aerial work platform for all-welded steel truss girder bridge and construction method of scattered part type cantilever assembly aerial work platform
The invention discloses a spare part type cantilever assembly aerial work platform for an all-welded steel truss girder bridge and a construction method of the spare part type cantilever assembly aerial work platform. The aerial operation platform comprises a main body truss structure, a suspension operation platform, a transportation system, a platform forward moving measure structure and a temporary anchoring system. One end of the main truss structure is arranged on the constructed main bridge steel structure, the other end of the main truss structure extends out of the constructed main bridge steel structure to be arranged in a cantilever shape, one of the main truss structures is constructed through a platform forward moving measure, and the temporary anchoring system is connected with the constructed main bridge steel structure; the transportation system comprises a ground-bridge floor hoisting device, a bridge floor transportation device and a bridge floor-platform hoisting device. Therefore, by means of the aerial operation platform, transportation-welding assembly of spare parts of all the sections of the main bridge steel structure can be achieved one by one, so that construction of the all-welded main bridge steel structure is completed, and it is avoided that corresponding ground supports need to be erected when the sections are overall hoisted and installed.
本发明公开了一种用于全焊钢桁梁桥的散件式悬臂拼装空中作业平台及其施工方法。空中作业平台包括主体桁架结构、悬挂操作平台、运输系统、平台前移措施构造和临时锚固系统；主体桁架结构，一端设置在已施工完成的主桥钢结构上，另一端则伸出已施工完成的主桥钢结构以呈悬臂状设置，且所述的主体桁架结构择一通过平台前移措施构造、临时锚固系统与已施工完成的主桥钢结构连接；运输系统包括地‑桥面吊装装置、桥面运输装置以及桥面‑平台吊装装置。由此可见，通过本发明所述的空中作业平台，可以逐一实现主桥钢结构的各节段的散件运输‑焊接拼装，从而完成全焊主桥钢结构施工，避免节段整体吊运、安装需要搭设相应的地面支架。
