Steel shell-concrete composite orthotropic bridge deck slab structure and preparation method
The invention belongs to the technical field of bridge engineering, and particularly discloses a steel shell-concrete composite orthotropic bridge deck slab structure and a preparation method. Comprising an upper steel plate, a lower steel plate and a plurality of perforated T-shaped ribs, the upper steel plate and the lower steel plate are arranged in parallel, the perforated T-shaped ribs are arranged in parallel in the longitudinal direction, webs of the perforated T-shaped ribs are welded to the upper steel plate, and flanges of the perforated T-shaped ribs are riveted to the lower steel plate. The upper steel plate and the lower steel plate are connected to form a steel shell structure, and the upper steel plate and the lower steel plate are anchored in the filled concrete through the reinforced concrete tenons and the shear studs formed by the perforated T-shaped ribs and the core rod steel bars, so that the steel shell-concrete composite plate which is stressed together is formed. The anti-bending rigidity is large, the fatigue problem of welding seams of the stiffening ribs and the steel top plate is solved, the performance of the steel shell and concrete is fully played, and the problems that a traditional combined bridge deck slab is prone to cracking under the action of hogging moment and is too heavy are solved.
本发明属于桥梁工程技术领域，具体公开了一种钢壳‑混凝土复合正交异性桥面板结构及制备方法。包括钢壳结构、内填混凝土、设于钢壳结构底部的纵、横加劲肋，以及板端连接结构，其中，钢壳结构包括平行布置的上钢板、下钢板和多根沿纵向平行布置的开孔T形肋，开孔T形肋的腹板与上钢板焊接、翼缘与下钢板铆接，将上、下钢板连接为钢壳结构，开孔T形肋与芯棒钢筋形成的钢筋混凝土榫和剪力栓钉将上、下钢板锚固于内填混凝土中，形成共同受力的钢壳‑混凝土复合板。本发明抗弯刚度大，解决了加劲肋与钢顶板焊缝的疲劳问题，充分发挥了钢壳和混凝土性能，解决传统组合桥面板在负弯矩作用下易开裂及重量过大的问题。
