Construction process of wet joint connecting structure of prefabricated bridge deck slab
The invention discloses a construction process of a wet joint connecting structure of a prefabricated bridge deck slab. The construction process is characterized in that firstly, a welding nail, a steel plate and a steel bar lifting ring are combined into an integral structure, the welding nail is connected with the bridge deck slab, a welding nail side of the steel plate is attached to a bottom surface of a concrete plate, epoxy mortar is laid on the other side of the steel plate, the steel plate is attached to a bottom surface of the other bridge deck slab, and finally, the overall structureis connected with the embedded steel bars exposed out of ends of bridge decks on two sides through steel bars in a welding or binding mode, the two adjacent bridge deck slabs and the prefabricated bridge deck wet joint connecting structure are combined into a whole, and the bottom of a wet joint between the two adjacent bridge deck slabs is completely sealed by the steel plate. Compared with theprior art, the construction process is advantaged in that procedures of mounting and dismounting the formwork during wet joint construction of a traditional prefabricated bridge deck slab on site arereduced, the construction speed is increased, the connection quality of the wet joint is guaranteed, the bearing capacity of the structure at the wet joint is improved, and the safety reserve of the structure is increased.
本发明公开了一种预制桥面板湿接缝连接结构的施工工艺，先将焊钉、钢板和钢筋吊环组合成一个整体结构，再将焊钉与一个桥面板相连，使得钢板有焊钉侧与混凝土板底面贴合，钢板另一侧铺设环氧砂浆，将钢板与另一桥面板底面贴合，最后通过焊接或绑扎的方式将该整体结构分别通过钢筋与两侧的桥面板端部露出的预埋钢筋相连，将相邻的两个桥面板与预制桥面板湿接缝连接结构结合成一个整体，相邻两个桥面板之间的湿接缝底部完全被钢板封住。与现有技术相比，本发明减少了现场传统预制桥面板湿接缝施工时模板安装与拆除的工序，加快了施工速度，并保证了湿接缝处的连接质量，提高了湿接缝处结构的承载力，增加了结构的安全储备。
