Orthotropic combined bridge deck slab with replaceable damage elements and construction method thereof
The invention belongs to the technical field of bridge construction, and particularly relates to an orthotropic combined bridge deck slab with replaceable damage elements and a construction method thereof. The orthotropic combined bridge deck slab is suitable for large-span bridges which are large in traffic volume and need rapid recovery of use functions. The orthotropic combined bridge deck slab comprises a steel structure component and a concrete slab poured at the top of the steel structure component; the steel structure component comprises a reinforcing mesh, a top plate, a plurality of cap-shaped longitudinal ribs, a plurality of transverse partition plates and replaceable damage elements. The top plate is laid at the bottom of the reinforcing mesh, the bottom of the top plate is connected with a plurality of cap-shaped longitudinal ribs arranged at intervals, and the top flange is detachably connected with the top plate through a high-strength bolt connecting pair A; the transverse partition plates are longitudinally arranged and perpendicular to the cap-shaped longitudinal ribs, and the transverse partition plates are detachably connected with bottom plates of the U-shaped rib plates of the cap-shaped longitudinal ribs through replaceable damage elements which are used for reducing fatigue stress amplitude and are convenient to replace. The problems that an orthotropic bridge deck slab is prone to fatigue failure and inconvenient to maintain are solved, rapid replacement and maintenance can be achieved under the condition that traffic is not interrupted, and the using function is recovered.
本发明属于桥梁建造技术领域，具体涉及一种适用于交通量大且需要快速恢复使用功能的大跨度桥梁的可更换损伤元的正交异性组合桥面板及其施工方法。本发明包括钢结构部件和浇筑于钢结构部件顶部的混凝土板；钢结构部件包括钢筋网、顶板、若干帽型纵肋、若干横隔板和可更换损伤元；顶板铺设于钢筋网的底部，顶板的底部连接有间隔排布的若干帽型纵肋，上翼缘通过高强螺栓连接副A与顶板可拆卸连接；横隔板纵向设置并且垂直于帽型纵肋，横隔板与帽型纵肋的U形肋板的底板通过用于降低疲劳应力幅并且便于更换的可更换损伤元可拆卸连接。本发明解决了正交异性桥面板易疲劳失效且不方便维修的问题，可在不中断交通的情况下快速更换维修，恢复使用功能。
