Locally replaceable orthotropic steel bridge deck structure and construction method thereof
The invention discloses a locally replaceable orthotropic steel bridge deck structure and a construction method thereof. The structure comprises a bridge deck laid at the top of a main beam of a longitudinal external bridge body; the bridge deck slab can be divided into a heavy lane, a middle lane, a light lane and an emergency lane in the transverse direction. The top plate of the bridge deck can be divided into a heavy lane top plate and a non-heavy lane top plate; the heavy lane comprises a first diaphragm plate and a heavy lane top plate; the bottom of the heavy lane top plate is connected with longitudinal rolled U ribs through pulling rivets; the light lane, the middle lane and the emergency lane comprise second transverse partition plates and non-heavy lane top plates; a longitudinal cold-bending U-shaped rib is welded at the bottom of the non-heavy lane top plate; the heavy lane adopts pulling rivet connection to replace traditional welding seam connection, so that the problems of stress concentration and thermal stress generated in the welding process are relieved; when the U rib is used for a long time or is locally damaged, the single U rib can be quickly disassembled and replaced without integrally replacing the bridge floor structure, so that the traffic interruption time is effectively shortened.
一种局部可更换正交异性钢桥面板结构及其施工方法，该结构包含铺设于纵向的外部桥体的主梁顶部的桥面板；所述桥面板可沿横向分为重车道、中车道、轻车道和应急车道；桥面板的顶板可分为重车道顶板和非重车道顶板；重车道包含第一横隔板和重车道顶板；重车道顶板底部通过拉铆钉连接纵向的轧制U肋；轻车道、中车道和应急车道包含第二横隔板和非重车道顶板；非重车道顶板的底部焊接有纵向的冷弯U肋；重车道采用拉铆钉连接替代传统的焊缝连接，缓解了焊接过程中产生的应力集中和热应力问题；U肋在长期使用或局部损坏时，可快速拆卸和更换单个U肋，无需整体更换桥面结构，从而有效减少交通中断时间。
