Fabricated UHPC steel-concrete composite bridge deck slab and construction method thereof
The invention relates to the technical field of bridge construction, in particular to a fabricated UHPC steel-concrete combined bridge deck slab, and the bridge deck slab comprises a stepped steel plate formed through continuous film pressing; a prefabricated inverted-U-shaped UHPC bridge deck slab which is arranged above the stepped steel plate, wherein the inverted-U-shaped UHPC bridge deck slabis connected with the upper surface of the stepped steel plate through high-strength bolts; C40 concrete is poured between the inverted-U-shaped UHPC bridge decks, so the whole steel-concrete combined bridge decks form a whole, and an asphalt pavement layer is laid on the whole steel-concrete combined bridge decks. The inverted U-shaped UHPC bridge deck slab is connected with the stepped steel plates, so the bending rigidity of the bridge deck slab can be improved, and the fatigue resistance is improved; the inverted-U-shaped UHPC bridge deck slab is prefabricated and formed in a factory, sothe quality of components is easy to guarantee, and the on-site installation speed is high; the UHPC prefabricated plate is connected with the steel plate through the high-strength bolts, so maintenance and replacement are convenient. The invention further provides a construction method of the assembly type UHPC steel-concrete composite bridge deck slab.
本发明涉及桥梁施工技术领域，尤其涉及一种装配式UHPC钢混组合桥面板，包括：连续膜压成形的阶梯型钢板；预制的倒U型UHPC桥面板，设置在阶梯型钢板的上方，倒U型UHPC桥面板与阶梯型钢板的上表面通过高强螺栓相连接；并通过在倒U型UHPC桥面板之间浇筑C40混凝土，将整个钢混组合桥面板形成一个整体，并在其上方铺设沥青铺装层。本发明通过倒U型UHPC桥面板与阶梯型钢板相连接，可以增加桥面板的抗弯刚度，提高耐疲劳性能；倒U型UHPC桥面板通过工厂预制成型，构件质量容易保证，现场安装速度快；UHPC预制板与钢板通过高强螺栓连接，方便维护与更换。本发明还请求保护一种装配式UHPC钢混组合桥面板的施工方法。
