Scattered cable saddle for suspension bridge
The invention relates to a splay cable saddle for a suspension bridge, the splay cable saddle comprises two sub-saddle bodies, each sub-saddle body comprises a cable bearing groove, a first transverse stiffening rib arranged on the inner side of the cable bearing groove and a saddle body bottom plate, the cable bearing grooves are formed in the saddle body bottom plates, and the two first transverse stiffening ribs connect the cable bearing grooves of the two sub-saddle bodies into a whole; the cable bearing groove comprises a bottom groove connected with the saddle body bottom plate, a first side wall and a second side wall, the first side wall and the second side wall longitudinally extend from the two sides of the bottom groove, the bottom groove is provided with a plurality of bottom groove paths, and the line shapes of the bottom groove paths, the first side wall and the second side wall are gentle abduction curves formed by uniform transition connection of straight lines and circular arcs. The gentle abduction curve comprises a first straight line section, an arc section and a second straight line section which are connected in sequence. The invention provides a splay cable saddle for a suspension bridge, which can solve the problems of anchoring space conflict, overlarge size of the side wall of a cable bearing groove of the splay cable saddle, overlarge shearing force borne by a base of the splay cable saddle and the like when double main cables in a heavy-load, large-span and rail (railway) combined construction suspension bridge adopt small-spacing co-anchoring.
本申请涉及一种悬索桥用散索鞍，散索鞍包括两个子鞍体，子鞍体包括承揽槽、设于承揽槽内侧的第一横向加劲肋、以及鞍体底板，承揽槽设于鞍体底板上，两个第一横向加劲肋将两个子鞍体的承揽槽连接成整体；承揽槽包括与鞍体底板连接的底槽、自底槽两侧纵向延伸的第一侧壁和第二侧壁，底槽设有多个底槽槽路，底槽槽路、第一侧壁、第二侧壁的线形均为直线与圆弧均匀过渡连接的平缓外展曲线，平缓外展曲线包括顺序连接的第一直线段、圆弧段和第二直线段。本发明提供一种悬索桥用散索鞍，能解决在重载、大跨、公轨(铁)合建悬索桥中双主缆采用小间距共锚时面临的锚固空间冲突、散索鞍承揽槽侧壁尺寸过厚、散索鞍底座承受过大剪力等难题。
