Assembly type orthotropic steel bridge deck structure with combination of groove-shaped longitudinal ribs and L-shaped longitudinal ribs
The invention discloses a fabricated orthotropic steel bridge deck structure combined by groove-shaped longitudinal ribs and L-shaped longitudinal ribs. The orthotropic steel bridge deck structure comprises a steel top plate, the groove-shaped longitudinal ribs, the L-shaped longitudinal ribs, transverse partition plates and inverted-T-shaped transverse ribs. The steel top plate serves as an upper top plate of the orthotropic steel bridge deck structure, the bottom face of the steel top plate is fixedly connected with an upper flange of the groove-shaped longitudinal rib in the traffic lane and heavy lane area of the bridge deck, and the bottom face of the steel top plate is fixedly connected with the top face of the L-shaped longitudinal rib in the overtaking lane and emergency parking strip area of the bridge deck. A plurality of boot-shaped holes are formed in the upper portions of the transverse partition plates and the upper portions of the inverted-T-shaped transverse ribs. The top faces of the transverse partition plates and the top faces of the inverted-T-shaped transverse ribs are fixedly connected with the bottom face of the steel top plate. The groove-shaped longitudinal ribs and the L-shaped longitudinal ribs penetrate through the multiple boot-shaped holes of the transverse partition plate and the inverted-T-shaped transverse ribs. By means of the orthotropic steel bridge deck, the rigidity matching and deformation coordination capacity of the orthotropic steel bridge deck can be effectively improved, stress concentration is avoided, it is guaranteed that the anti-fatigue capacity and anti-fatigue requirements of bridge deck structures in different areas are more coordinated, and therefore the fatigue problem of a traditional orthotropic steel bridge deck is effectively solved.
本公开是一种装配式槽型纵肋与L型纵肋组合的正交异性钢桥面板结构，包括钢顶板、槽型纵肋、L型纵肋、横隔板和倒T型横肋。钢顶板作为该正交异性钢桥面板结构的上顶板，在桥面的行车道和重车道区域其底面与槽型纵肋的上翼缘固接，在桥面的超车道和紧急停车带区域其底面与L型纵肋的顶面固接；横隔板和倒T型横肋的上部均设置有多个靴形孔，横隔板和倒T型横肋的顶面均与钢顶板的底面固接；槽型纵肋、L型纵肋均穿过横隔板和倒T型横肋的多个靴形孔。利用本公开，能有效提升正交异性钢桥面板的刚度匹配和变形协调能力，避免应力集中，并保障不同区域的桥面板结构抗疲劳能力和抗疲劳需求更加协调，从而有效解决了传统正交异性钢桥面的疲劳问题。
