Orthotropic steel bridge deck slab
The invention relates to the technical field of bridge engineering and an orthotropic steel bridge deck slab. The orthotropic steel bridge deck slab comprises a slab body, a plurality of web plates, first longitudinal stiffening ribs and second longitudinal stiffening ribs; the web plates are arranged on the lower surface of the slab body in the width direction of the slab body; one pair of firstlongitudinal stiffening ribs is arranged on the two opposite sides of the web plates in the width direction of the slab body; the second longitudinal stiffening ribs are arranged between the pair of first longitudinal stiffening ribs between every two adjacent web plates; and the height of the first longitudinal stiffening ribs is larger than that of the second longitudinal stiffening ribs. With the orthotropic steel bridge deck slab provided by the invention adopted, stress concentration at the positions of the web plates is reduced, and cracks generated by bridge deck pavement are avoided.
本发明涉及桥梁工程技术领域，具体涉及一种正交异性钢桥面板，包括：板体；多个腹板，沿所述板体的宽度方向设于板体的下表面；第一纵向加劲肋和第二纵向加劲肋，一对所述第一纵向加劲肋沿所述板体的宽度方向分设在所述腹板的相对两侧，所述第二纵向加劲肋设于相邻两个所述腹板之间的一对所述第一纵向加劲肋之间，且所述第一纵向加劲肋的高度大于所述第二纵向加劲肋的高度。本发明提供了一种降低腹板位置的应力集中，避免桥面铺装产生裂缝的正交异性钢桥面板。
