Mounting method of tie bars of arch bridge
The invention relates to the technical field of arch bridge construction, and particularly relates to a mounting method of tie bars of an arch bridge. After an arch rib is erected, installation of sling parts is matched with a transverse supporting part to build a traction catwalk for temporarily supporting a first tie bar, the first tie bar is installed and tensioned, a bridge deck beam is hoisted, then a second tie bar is mounted and tensioned, and finally, after ancillary facilities are completed, a third tie bar is installed and tensioned till the arch bridge tie bars reach the finished bridge tie bar force, so the sag effect of the tie bar components is effectively reduced, all the tie bar components are tensioned in place at a time, the tie bar force adjusting frequency is reduced, the tensioning effect is improved, the construction risk is reduced, construction safety is guaranteed, and the construction period is shortened.
本发明涉及拱桥施工技术领域，特别涉及一种拱桥的系杆的安装方法，在拱肋架设完成后，即安装吊索部件配合横向支撑部件，搭设牵引猫道，用于临时支承第一系杆并对所述第一系杆进行安装及张拉，然后在吊装桥面梁之后，安装所述第二系杆并张拉，最后在附属设施完工后，安装所述第三系杆并张拉至拱桥系杆达到成桥系杆力，有效减小系杆构件的垂度效应，所有系杆构件均实现一次张拉到位，减少系杆力的调整次数，提高张拉效果，降低施工风险，保证施工安全，缩短施工周期。
