Construction method of steel arch rib structure for integrally lifting closure without closure section
The invention belongs to the technical field of steel arch rib structure construction, and particularly relates to a closure-section-free integral lifting closure steel arch rib structure construction method which comprises the following steps: step 1, construction preparation: after a steel box girder is pushed and falls in place, the linear shape of the steel box girder is adjusted in place according to a monitoring instruction; according to the construction method of the steel arch rib structure for overall lifting closure of the closure-free section, the splicing clamping connecting mechanism is arranged, so that the rapid clamping and disassembling functions are achieved, the arch rib connecting time can be shortened, and the construction progress of the whole structure is accelerated; the work of welding and cutting the temporary stacking plate is reduced, and the dependence on high-skill welders can be reduced, so that the labor cost is reduced; the on-site welding operation is reduced, so that the safety risk caused by the on-site welding operation is reduced; waste materials generated by welding operation and cutting are reduced, and environmental protection is facilitated; discontinuity of materials and structures caused by welding of a plurality of stacking plates is avoided, and improvement of the overall performance of the structure is facilitated.
本发明属于钢拱肋结构施工技术领域，尤其是一种无合龙段整体提升合龙的钢拱肋结构施工方法，包括以下步骤：步骤一、施工准备,钢箱梁顶推并落梁到位后，按监控指令将钢箱梁线形调整到位。该无合龙段整体提升合龙的钢拱肋结构施工方法，通过设置拼接装夹连接机构达到了快速装夹和拆卸功能可以减少拱肋连接的时间，加快整个结构的施工进度；减少了焊接和切割临时码板的工作，可以降低对高技能焊工的依赖，从而降低人工成本；减少了现场焊接作业，也就降低了由此引发的安全风险；减少了焊接作业和切割产生的废料，有利于环境保护；避免了焊接多个码板造成的材料和结构上的不连续性，有助于提高结构整体性能。
