Abstract

本实用新型涉及拱桥,尤其涉及的是钢结构拱桥,主要是由多排拱形的钢架并行排列并往钢架浇灌混凝土而成,所述钢架是由多个托箱沿拱形走向拼接而成,所述托箱的横截面为上底比下底宽的梯形,所述托箱由间隔设置的横隔板分成多个空格,所述空格内装有机械箱。本实用新型钢架是在陆地上直接拼接而成,再由吊具将起吊到河道并安装固定,能够提高施工效率,施工过程更加安全;上底比下底宽的等腰梯形的托箱连接定位成拱形的拱架,精度更加精确。
The utility model relates to arch bridges, particularly to a steel structure arch bridge, which is mainly formed by concreting multiple rows of arch steel frames parallelly arrayed and pouring concrete on the arch steel frames. Each steel frame is formed by splicing a plurality of support boxes along the arch; the cross section of each support box is shaped like a trapezoid with a wider upper bottom and a narrower lower bottom; each support box is divided into a plurality of spaces through diaphragm plates arranged at intervals; and mechanical boxes are mounted inside the spaces. According to the utility model, the steel frames are formed through direct assembly on land, and then are slung to a river channel to be mounted and fixed, so that the construction efficiency is improved, and the construction process is safer; the support boxes with the wider upper bottoms and the narrower lower bottoms are connected and positioned into the arched arch bridge, and the precision is higher.
