Half-through steel arch bridge and construction method
The invention relates to a steel arch bridge, in particular to a half-through steel arch bridge and a construction method. The half-through steel arch bridge comprises a main beam and two steel structure arch ribs arranged in a spaced mode, the main beam is located between the two steel structure arch ribs, a wind brace is fixedly connected between the two steel structure arch ribs, the wind brace is located above the main beam, a rigid connecting rod is fixedly connected to the wind brace, and the rigid connecting rod is fixedly connected to the steel structure arch ribs. And one end, far away from the wind brace, of the rigid connecting rod is fixedly connected with the main beam. According to the half-through steel arch bridge, the number of structures connected with the steel structure arch ribs is greatly reduced, the welding amount borne by the arch ribs in the construction process is reduced, the influence of the local stress concentration problem caused by welding on the bridge is reduced, loads borne by the rigid connecting rods are transmitted to the wind braces, and therefore the rigidity of the bridge is improved. And then the force is transmitted to the steel structure arch rib through the wind brace, so that the whole force transmission path is very clear, the stress of the steel structure arch rib is optimized, and the checking calculation of a bridge is more convenient.
本发明涉及一种钢拱桥，特别是一种中承式钢拱桥及施工方法。其中中承式钢拱桥包括主梁和两条间隔设置的钢结构拱肋，所述主梁位于两条钢结构拱肋之间，两条所述钢结构拱肋之间固定连接有风撑,所述风撑位于所述主梁上方，所述风撑上固定连接有刚性连接杆，所述刚性连接杆远离所述风撑的一端与所述主梁固定连接。本申请所述的中承式钢拱桥，大大降低了与钢结构拱肋连接的结构数量，降低了拱肋施工时所受到的焊接量，降低了焊接造成的局部应力集中问题对桥梁的影响，所述刚性连接杆承受的载荷传递至所述风撑上，再通过所述风撑传递至所述钢结构拱肋上，从而使得整个传力路径很明确，从而优化所述钢结构拱肋的受力，更方便桥梁校核计算。
