Double-sided welding orthotropic steel bridge deck slab with cross details of transverse partition plates and longitudinal ribs
The invention discloses a double-sided welding orthotropic steel bridge deck slab with cross details of transverse partition plates and longitudinal ribs, which comprises transverse partition plates,U-shaped ribs and a steel top plate, and the transverse partition plates are provided with U-shaped rib holes and transverse partition plate through holes which communicate with each other; the U-shaped ribs are arranged in the U-shaped rib holes and are welded on the steel top plate and the side walls of the U-shaped rib holes; the transverse partition plate through holes are formed below the U-shaped rib holes, and the transverse partition plate through holes do not communicate with the U-shaped rib holes. The double-sided welding orthotropic steel bridge deck slab with cross details of transverse partition plates and longitudinal ribs has the advantages that the dominant fatigue cracking modes are longitudinal rib bottom plate and transverse partition plate crossed structure detail longitudinal rib end weld toe cracking, so that the dominant fatigue cracking modes of the steel bridge deck slab structure system migrate, and the fatigue performance of the longitudinal rib and top plate structure detail weld root positions is improved.
本发明公开了一种横隔板与纵肋交叉细节的双面焊正交异性钢桥面板，包括横隔板、U肋和钢顶板，所述横隔板上设置贯通的U肋孔和横隔板通孔；所述U肋设置于所述U肋孔内并焊接于所述钢顶板和所述U肋孔侧壁；所述横隔板通孔设置于所述U肋孔下方，且所述横隔板通孔与所述U肋孔不连通。本发明一种横隔板与纵肋交叉细节的双面焊正交异性钢桥面板，主导疲劳开裂模式均为纵肋底板与横隔板交叉构造细节纵肋端部焊趾开裂，使得钢桥面板结构体系的主导疲劳开裂模式发生迁移，提升纵肋与顶板构造细节焊根位置的疲劳性能。
