Combined structure of skew corrugated steel arch bridge
The invention discloses a combined structure of a skew corrugated steel arch bridge, which comprises a road surface, a corrugated steel plate arch bridge arranged below the road surface, and an arched beam. The corrugated steel arch bridge is formed by splicing a plurality of corrugated steel plates, a non-90-degree included angle is formed between the circle center axis of an outer arch of the corrugated steel arch bridge and the road surface direction, the corrugation direction is perpendicular to the circle center axis of the outer arch, the arched beams are arranged at the two ends of the corrugated steel arch bridge and connected with the end faces of the corrugated steel plates, and the direction of the arched beams is parallel to the road surface direction. Wherein the shear nails are arranged on the upper surfaces of the triangular corrugated steel plates formed by obliquely cutting off corrugations at the two ends of the corrugated steel plate arch bridge and the adjacent corrugated steel plates, the reinforcing mesh is arranged on the shear nails, the concrete layer is poured on the reinforcing mesh, and the concrete layer, the shear nails and the reinforcing mesh jointly form a reinforced concrete structure. According to the combined structure, the oblique crossing corrugated steel plate arch bridge combined structure saves materials, reduces the construction cost and meanwhile keeps the bearing capacity of the arch bridge not to be reduced.
本发明公开了一种斜交波纹钢板拱桥组合结构，包括路面、设置于路面下方的波纹钢板拱桥及拱梁。波纹钢板拱桥由多片波纹钢板拼接而成，波纹钢板拱桥的外拱的圆心轴线与路面方向呈非90度夹角，波纹方向与外拱的圆心轴线垂直，拱梁设置于波纹钢板拱桥的两端，与波纹钢板的端面连接，拱梁方向与路面方向平行。其中波纹钢板拱桥两端的波纹被斜向切断的呈三角形波纹钢板和相邻的波纹钢板的上表面设有剪力钉，剪力钉上设有钢筋网，钢筋网上浇筑有一层混凝土层，所述混凝土层与剪力钉及钢筋网共同形成钢筋混凝土结构。根据上述技术方案的斜交波纹钢板拱桥组合结构，在节约材料，降低工程造价的同时，保持拱桥的承载力不降低。
