Orthotropic bridge deck
The invention relates to an orthotropic bridge deck, and belongs to the technical field of bridge structures. The bridge deck slab comprises a main steel plate, transverse ribs, U-shaped ribs and a concrete slab, the transverse ribs are connected with the lower surface of the main steel plate, the U-shaped ribs are connected with the upper surface of the main steel plate, the concrete slab is connected with the U-shaped ribs, and an asphalt concrete layer is laid on the concrete slab. The U-shaped ribs are reversely arranged, the structural design of the lower portion of the main steel plate is simplified, the transverse ribs and the transverse partition plate are not interfered by the U-shaped ribs in the conventional design any more, the manufacturing process is simplified, and the manufacturing progress is accelerated; fatigue cracking at the U-shaped ribs and the diaphragm plates in a conventional orthotropic bridge deck is avoided, and the service life of the structure is prolonged; after the shear connectors are welded on the U-shaped ribs, precast concrete slabs can be mounted, so that the bending resistance of the bridge deck is improved, and the material properties of the main steel plate and the concrete slabs are fully exerted; concrete is poured into the U-shaped ribs, and the rigidity of the orthotropic bridge deck slab and the rigidity of the whole steel box girder can be further improved.
本发明涉及一种正交异性桥面板，属于桥梁结构技术领域。该桥面板包括主钢板、横肋、U形肋和混凝土板，横肋与主钢板下表面连接，U形肋与主钢板上表面连接，混凝土板与U形肋连接，混凝土板上铺筑沥青混凝土层。本发明将U形肋反置，简化了主钢板下的结构设计，使横肋和横隔板不再受到常规设计中的U形肋的干扰，简化了制作工艺，加快了制作进度；避免了常规的正交异性桥面板中发生在U形肋和横隔板处的疲劳开裂，提高了结构寿命；在U形肋上焊接剪力连接件后，可安装预制混凝土板，提高了桥面板的抗弯能力，主钢板和混凝土板的材料性能得到充分发挥；在U形肋内灌注混凝土，可进一步正交异性桥面板的刚度和整个钢箱梁的刚度。
