Rhombic-sectioned concrete-filled steel tube arch rib
The invention discloses a rhombic-sectioned concrete-filled steel tube arch rib , and belongs to the technical field of arch bridge construction. The arch rib comprises steel tubes, the steel tubes are filled with concrete, the four limb steel tubes are connected with one another to form the rhombic section arch rib, the adjacent steel tubes are connected through an outer web, and the two limb steel tubes in the middle of the rhombic section arch rib are connected through a transverse connector. The arc rib is formed by combining an upper most stable triangular section and a lower most stabletriangular section, and can ensure that the structure conforms to plane section assumption; the main stress steel tube is located in the center of the arch face, and structural stress is smoother; thecompression area of the arch rib is increased by filling concrete into a core area surrounded by the steel tube and the outer web, compared with a truss arch rib, the compression resistance bearing capacity is improved, and the structural durability is ensured; and the appearance of multi-group arc connection and the curved arch rib complement each other, the overall shape of the bridge is more flexible, and the application range of the concrete arch bridge is widened.
本发明公开了一种菱形断面钢管混凝土拱肋，属于拱桥施工技术领域。本发明包括钢管，所述的钢管内部填充有内填混凝土，四肢钢管相互连接共同组成菱形断面拱肋，相邻的钢管之间连接有外腹连接，菱形断面拱肋的中部的两肢钢管相互之间连接有横联。本发明由上下各一组最稳定的三角形断面合并构成，可保证结构符合平截面假定；主受力钢管位于拱面中心，结构受力更加流畅；钢管和外腹连接包围的核心区域通过内填混凝土增大了拱肋受压面积，与桁架拱肋相比提高了抗压承载力，确保了结构耐久性，多组弧形相连的外观，与曲线拱肋相得益彰，使桥梁总体造型更加柔美灵动，拓宽了混凝土拱桥的适用范围。
