Prefabricated bridge deck formwork-free cast-in-place wet joint structure
The invention discloses a prefabricated bridge deck formwork-free cast-in-place wet joint structure, and belongs to the technical field of bridge design, the prefabricated bridge deck formwork-free cast-in-place wet joint structure comprises a plurality of prefabricated slabs arranged in the bridge direction and cast-in-place sections continuously laid between every two adjacent prefabricated slabs, and the two ends of each prefabricated slab in the bridge direction are provided with semi-U-shaped structure extension sections; the semi-U-shaped structure extension sections of every two adjacent prefabricated slabs are in butt joint to form a whole U-shaped notch to serve as a bottom die of the cast-in-place section, the cast-in-place section is connected with the two adjacent prefabricated slabs in a pouring mode, and the prefabricated slabs and the cast-in-place section are made of concrete materials or ultra-high-performance concrete materials. On-site template loading and unloading work is omitted, construction is facilitated and the manufacturing cost is reduced, potential safety hazards of passing under the bridge in the construction process are avoided, and the quality of the wet joint structure is improved to the maximum extent.
本发明公开了一种预制桥面无模板现浇湿接缝结构，属于桥梁设计技术领域，包括多块顺桥向排布的预制板，以及连续铺设在相邻两块预制板之间的现浇段，预制板顺桥向两头设置有半“U”形状构造延伸段，相邻两块预制板的半“U”形状构造延伸段对接合成一个整“U”形状凹口，作为现浇段的底模，现浇段与相邻两块预制板浇筑连接，预制板和现浇段采用混凝土材料或者超高性能混凝土材料，本发明免除现场模板装卸工作，方便施工，降低造价，避免施工过程中桥下通行安全隐患，最大程度提高湿接缝结构质量。
