Curved beam and space arch combined system footbridge
The invention discloses a curved beam and space arch combined system footbridge which comprises an arch rib body, a main beam body and a plurality of suspenders, the arch rib body is in a space inclined arch shape, the main beam body is of a curved beam structure, and the two ends of the arch rib body are fixedly connected with the two ends of the main beam body respectively to form arched beam fixing points. The arch rib body is divided into an upper arch rib and two lower arch ribs which are respectively arranged at two ends of the upper arch rib by the two arch beam fixing points, and the main beam body is divided into a mid-span main beam and two side-span main beams which are respectively arranged at two ends of the mid-span main beam by the two arch beam fixing points. The curve protruding direction of the projection of the mid-span main beam on the horizontal plane is opposite to the curve protruding direction of the projection of the upper arch rib on the horizontal plane. The plurality of suspenders are uniformly distributed between the mid-span main beam and the upper arch rib. During construction, the two lower arch ribs are connected with an external bearing platform, and the two side-span main beams are supported on a pier or a ground foundation, so that the pedestrian bridge structure forms tension stress, and the stability of the structure is improved.
本发明公开了一种曲梁空间拱组合体系人行桥，包括拱肋主体、主梁主体、多个吊杆，拱肋主体为空间倾斜拱形状，主梁主体为曲线梁结构，拱肋主体的两端分别与主梁主体的两端固结连接并形成拱梁固结点，两个拱梁固结点将拱肋主体分为上拱肋、分别设置于上拱肋两端的两个下拱肋，两个拱梁固结点将主梁主体分为中跨主梁、分别设置于中跨主梁两端的两个边跨主梁，中跨主梁在水平面投影的曲线凸出方向与上拱肋在水平面投影的曲线凸出方向呈相反设置；多个吊杆均布于中跨主梁与上拱肋之间。在建造时，两个下拱肋连接与外设的承台，而两个边跨主梁支承于桥墩或地面基础之上，使人行桥结构形成对拉受力，增加了结构的稳定性。
