Fabricated reinforcement-free UHPC prefabricated bridge deck slab and rapid splicing method
The invention discloses an assembly type reinforcement-free UHPC prefabricated bridge deck slab and a rapid assembly method. UHPC serves as a main material of the prefabricated bridge deck slab, a constraint shell serves as a UHPC forming formwork, the constraint shell and the UHPC are connected through connecting studs and small-diameter steel sleeves, and the constraint shell is formed through metal plate cutting, bending and welding. A partition plate is placed in the shell or a steel sleeve is welded in the shell, and the steel sleeve where the installation penetrating hole is located is vertically fixed to the bottom face or the partition plate extending from the surrounding plate. And the ultra-high performance concrete and the constraint shell form a prefabricated bridge deck slab in a pouring mode. The prefabricated bridge deck slab is prefabricated in a factory, the material characteristics of UHPC are fully played, the structural form of the UHPC deck slab is optimized, the on-site steam curing link is omitted, and the problems that the on-site construction quality of a traditional UHPC bridge deck slab is difficult to control and prone to cracking, and the performance of the UHPC deck slab is unstable due to the fact that steel bars affect fiber distribution are solved.
本发明公开了一种装配式无配筋UHPC预制桥面板及快速拼装方法，该桥面板以UHPC作为预制桥面板主要材料，约束壳体充当UHPC成型模板，约束壳体与UHPC通过连接栓钉和小直径钢套筒连接，约束壳体通过钣金裁切、折弯、焊接的成型的约束壳体，并在壳体内放置隔板或者焊接钢套筒，该安装穿孔所在的钢套筒以垂直的方式固定在自围合板材延伸而来的底面或者隔板上；超高性能混凝土以浇筑的方式与约束壳体形成预制桥面板。本预制桥面板在工厂预制完成，充分发挥UHPC的材料特性，优化UHPC面板结构形式，省去了现场蒸汽养护环节，解决了传统UHPC桥面板现场施工质量难控制、易开裂、钢筋影响纤维分布导致UHPC面板性能不稳定等问题。
