Forked bridge pier suitable for multiple main beams
The invention discloses a forked bridge pier suitable for multiple main beams. The forked bridge pier comprises a bridge pier forking structure and a pier top hinged support. The bridge pier bifurcation structure comprises two bifurcation piers in the bridge direction, two bifurcation piers in the transverse bridge direction and a bifurcation transition section, and the two bifurcation piers in the bridge direction and the two bifurcation piers in the transverse bridge direction are connected with a main pier through the bifurcation transition section. The bridge pier forking structure is mainly composed of the four forking piers and the forking transition section, the stability of the main beam structure is guaranteed, and the landscape effect of the pedestrian overpass is improved on the premise that the stress safety of the structure is guaranteed. The bifurcate pier in the bridge direction adopts a trapezoidal section, the first web plate is formed by hot bending, ridges are clear, and the appearance effect is good. The bottom plate of the bifurcated pier along the bridge direction is aligned with the second stiffening plate of the transition section; the second top plate of the transverse bridge direction bifurcated pier is aligned with the top plate stiffening plate, the second web plate is in butt joint with the gusset plate, the upper structure load is effectively transmitted to the bifurcated transition section, and the load is stably transmitted to the main pier through the bifurcated transition section.
本发明公开了一种适用于多主梁的分叉桥墩，包括桥墩分叉构造和墩顶铰支座；所述桥墩分叉构造包括两个顺桥向分叉墩、两个横桥向分叉墩和一个分叉过渡段，两个所述顺桥向分叉墩和两个所述横桥向分叉墩均通过一个所述分叉过渡段与主墩连接；本发明桥墩分叉构造主要由四个分叉墩和一个分叉过渡段组成，保证了主梁结构的稳定性，在保证结构受力安全的前提下，提升了人行天桥的景观效果。顺桥向分叉墩采用梯形截面，第一腹板热弯成形，棱线分明，外形效果较好。顺桥向分叉墩的底板与过渡段第二加劲板对齐；横桥向分叉墩的第二顶板与顶板加劲板对齐，第二腹板与节点板对接，将上部结构荷载分别有效传递至分叉过渡段，由分叉过渡段将荷载平稳传递至主墩。
