Fabricated bent cap connection construction method and bent cap connection structure
The invention relates to an assembly type bent cap connection construction method and a bent cap connection structure, and the method comprises the steps that firstly, a prefabricated pier is partially embedded into a cast-in-place bearing platform, and then a prefabricated bent cap section is spliced with the prefabricated pier, so that a reserved steel bar at the top of the prefabricated pier is arranged in a grouting pipe in the prefabricated bent cap section in a penetrating manner; then connecting steel units are arranged between the adjacent end faces of the adjacent prefabricated bent cap sections so as to connect the adjacent prefabricated bent cap sections, and finally grouting is conducted in the grouting pipes; according to the construction method, the connection mode of grouting the grouting pipes in the prefabricated cover beam sections is adopted, safe and rapid installation and connection of the prefabricated cover beam sections and the prefabricated piers can be achieved, the construction cost is low, construction is rapid and convenient, the adjacent prefabricated cover beam sections are connected through the connecting steel units, the quality of the prefabricated cover beam sections is reduced, and the construction efficiency is improved. The whole construction process can be implemented in a construction site with a narrow space, large-scale mechanical equipment is not needed, and the method is suitable for dangerous bridge transformation of rural roads.
本申请涉及一种装配式盖梁连接施工方法及盖梁连接结构，其包括：先将预制墩部分埋入现浇承台，再将预制盖梁节段与预制墩进行拼接，以使预制墩顶部的预留钢筋分别穿设于预制盖梁节段内部的注浆管内，然后在相邻预制盖梁节段的相邻端面之间设置连接钢单元，以连接相邻预制盖梁节段，最后向注浆管内注浆；本申请提供的施工方法采用灌浆预制盖梁节段内部的注浆管的连接方式，可以实现预制盖梁节段与预制墩的安全、快速地安装和连接，施工成本低，施工快捷方便，利用连接钢单元连接相邻预制盖梁节段，既降低了预制盖梁节段的质量，方便机械设备吊装，整个施工过程可以在空间狭小的施工现场实施，无需用到大型机械设备，适用于于农村公路的危桥改造。
