Vertical continuous bridge stand column prefabricated assembly structure and construction method thereof
The invention relates to the technical field of bridge prefabrication and assembly, in particular to a vertical continuous bridge stand column prefabrication and assembly structure and a construction method thereof. Each pier column is composed of two prefabricated stand columns and a wet joint. After the prefabricated columns are constructed in a factory, transported to a site and installed on a bearing platform, a wet joint structure is locally arranged between the two prefabricated columns, so that the slenderness ratio of each column is reduced, and the stability coefficient and the bearing capacity of each column in a bending stress state are improved. The prefabricated pier column is continuous and complete in the height direction, and the structural integrity is good; the pier column is spliced, only local wet joint construction needs to be carried out on site, wet joint steel bars are connected in a lap joint mode, welding of the steel bars is not needed, and the site construction workload is small. The prefabricated stand columns can be poured with concrete through a horizontal method, construction is convenient, and the consistency of the appearance of the stand columns is not affected. Construction is simple, the construction quality is easy to control, the safety risk is low, and the operability of on-site construction is high.
本发明涉及桥梁预制拼装技术领域，具体地说是一种竖向连续的桥梁立柱预制拼装构造及其施工方法。每根墩柱由两根预制立柱和湿接缝组成。预制立柱在工厂施工，运至现场安装在承台上后，在两根预制柱之间局部设置湿接缝构造，以减小每根柱的长细比，提高其压弯受力状态下的稳定系数和承载力。预制墩柱沿高度方向连续完整，结构整体性好；墩柱自身的拼装，现场仅需局部进行湿接缝的施工，湿接缝钢筋通过搭接连接，钢筋无需焊接，现场施工工作量小。预制立柱可采用平卧法浇筑混凝土，方便施工，且不影响立柱外观的一致性。本发明施工简单，施工质量容易控制，安全风险低,现场施工的可操作性强。
