Wet joint connecting structure of prefabricated bridge deck slab
The invention discloses a wet joint connecting structure of a prefabricated bridge deck slab. The wet joint connecting structure comprises a steel plate, welding nails and steel bar lifting rings, wherein a plurality of welding nails are welded and fixed at one end of the steel plate, the welding nails are pre-buried at one end of the bridge deck slab when the bridge deck slab is prefabricated, anepoxy mortar laying area is arranged at the other end of the steel plate, the epoxy mortar laying area is for laying epoxy mortar, the shortest distance between the epoxy mortar laying area and the welding nails is larger than the width of the wet joint of every two adjacent bridge decks, the steel bar lifting rings are welded and fixed between the welding nails and the epoxy mortar laying area and are close to one side of the epoxy mortar laying area, and the welding nails, the steel bar hanging rings and the epoxy mortar laying area are located on the same surface of the steel plate. Compared with the prior art, the wet joint connecting structure is advantaged in that the procedures of mounting and dismounting the formwork during wet joint construction of a traditional prefabricated bridge deck slab on site are reduced, 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，包括钢板、焊钉和钢筋吊环；多个焊钉焊接固定于钢板的一端，焊钉用以在预制一个桥面板时预埋于桥面板的一端；钢板另一端设有环氧砂浆铺设区，环氧砂浆铺设区用以铺设环氧砂浆，环氧砂浆铺设区与焊钉的最短距离大于相邻两个桥面板湿接缝处的宽度；钢筋吊环焊接固定于焊钉与环氧砂浆铺设区之间且靠近所述环氧砂浆铺设区一侧；焊钉、钢筋吊环和环氧砂浆铺设区位于钢板的同一个面上。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。
