Supporting structure of bridge expansion joint and construction method
The invention relates to a supporting structure of a bridge expansion joint and a construction method, an expansion joint is reserved between two adjacent box girders of a bridge, and the supporting structure comprises a bottom template, two rows of oppositely arranged side templates and an end template; the bottom formwork is arranged at the bottom of the expansion joint and connected with the box girder; the side formworks are vertically arranged on the bottom formwork and can extend in the length direction of the expansion joint, and the side formworks are connected with reinforcing steel bars on the box girder through fasteners; end formworks are arranged at the two ends of the box girder and connected with the bottom formwork and the side formworks; a flexible water pipe is arranged between the two rows of side formworks and extends in the length direction of the expansion joint, a water opening is formed in the flexible water pipe, liquid is injected into the flexible water pipe through the water opening, the flexible water pipe is made to be in the stretching state so that the side formworks can be tightly pressed on the steel bars, and the liquid in the flexible water pipe is discharged through the water opening. And the flexible water pipe is in a contraction state so as to relieve the pressing force on the side template. Therefore, the expansion joint formed through pouring is linear, straight and smooth, and the appearance quality is high.
本公开涉及一种桥梁伸缩缝的支撑结构及施工方法，桥梁的两个相邻箱梁之间预留有伸缩缝，支撑结构包括底模板、两排相对设置的侧模板以及端模板；底模板设置在伸缩缝底部且与箱梁连接；侧模板竖直设置在底模板上且可沿伸缩缝的长度方向延伸，侧模板通过紧固件与箱梁上的钢筋连接；箱梁的两端设置有端模板，端模板与底模板和侧模板连接；两排侧模板之间设置有柔性水管，柔性水管沿伸缩缝的长度方向延伸，柔性水管上具有水口，通过水口向柔性水管内注入液体，使柔性水管处于伸展状态以将侧模板压紧在钢筋上，通过水口将柔性水管中的液体排出，使柔性水管处于收缩状态以解除对侧模板的压紧力。基于此，浇筑成型的伸缩缝线性直顺，外观质量高。
