Adjustable universal profile steel arch frame
In order to solve the technical problems existing in cast-in-place steel arches of existing reinforced concrete arch bridges, the invention provides an adjustable universal steel arch frame which comprises a support system, arch foot standard sections, standard sections, arch crown closure sections, adjusting screws, connecting steel pins and a transverse connecting system. The support system is arranged on the front edges of skewbacks on two banks and used for supporting the weight of a steel arch frame and a cast-in-place arch rib, the horizontal load of a support is borne by the skewbacks, the vertical load is transmitted to a foundation through a distribution beam and a sand cylinder, and the support is connected with an arch springing standard section through a steel pin. The lower ends of the arch foot standard sections are rotatably connected through connecting steel pins, the lower ends of every two adjacent standard sections are rotatably connected through connecting steel pins, the upper ends of the arch foot standard sections are connected through adjusting screws, and the upper ends of every two adjacent standard sections are connected through adjusting screws. The amplitude of the arch frame can be adjusted, the structure is simple, the stress is clear, and the compression stability of the square steel tube is good.
本发明针对现有钢筋砼拱桥现浇钢拱架存在的技术问题，提供一种可调节万能型钢拱架，其包括支座体系、拱脚标准节段、标准节段、拱顶合拢段、调节螺杆、连接钢销和横向连接系；所述支座体系布置于两岸拱座前缘，用于支撑钢拱架及现浇拱肋重量，支座水平荷载由拱座承受，竖向荷载通过分配梁及砂筒传递给地基，支座通过钢销连接拱脚标准节段；所述拱脚标准节段下端与标准节段下端之间以及相邻两个标准节段下端之间通过连接钢销可转动连接，所述拱脚标准节段上端与标准节段上端之间以及相邻两个标准节段上端之间通过调节螺杆连接，拱架幅度可调节、结构简洁、受力明确，方钢管受压稳定性好等诸多优点。
