Bridge stay cable lagging tensioning construction technology
The invention relates to the field of constructional engineering, in particular to a bridge stay cable lagging tensioning construction process which comprises the following steps: a) mounting a hanging basket; b) pre-pressing the hanging basket; c) mounting a bottom die and an outer die, mounting steel bar prestress, and mounting a template-like plate; d) pouring and curing concrete; according to the method, in the bridge forming state, although the stress of the main beam is different from that of an original working procedure, the tension cable force does not change correspondingly, the stress in the bridge forming state is basically the same as that of the original working procedure, and compared with the original working procedure, the construction progress is accelerated.
本发明涉及建筑工程领域，具体为一种桥梁斜拉索滞后张拉施工工艺，所述施工工艺步骤为：a）、安装挂篮；b）、挂篮预压；c）、底模、外模安装，钢筋预应力安装，类模板安装；d）、砼浇筑并养护；e）、张拉三向预应力束；f）、压浆，封锚；g）、挂篮前移施工的下一节段；h）、本梁端安装斜拉索张拉，本发明在成桥状态下主梁应力虽与原工序有所差别，但张拉索力没有相应发生变化，做到成桥状态下的应力与原工序基本相同，相对原工序，加快了施工进度。
