Connecting structure, fixing structure, new main cable system and construction method for replacing main cable of suspension bridge
The invention discloses a connecting structure for replacing a main cable of a suspension bridge. The connecting structure comprises an anchorage connecting structure, a cable saddle connecting structure and a sling connecting structure; the anchorage connecting structure comprises a cable strand connecting plate, a prestressed anchorage device cable penetrating hole channel penetrating through the upper end face and the lower end face of the cable strand connecting plate, an original pull rod hole and an anchor hole; the cable saddle connecting structure comprises a base and a new saddle bodylocated above the base; and the sling connecting structure comprises a new sling clamp buckled on a new main cable, an upper carrying pole beam installed at the lower end of the new sling clamp, anda lower carrying pole beam connected with the upper carrying pole beam through a tension rod. According to the connecting structure, the fixing structure, the new main cable system and the construction method for replacing the main cable of the suspension bridge, bridge traffic is not influenced in the construction process; and under the condition that the structural safety of a suspension bridgecable system is guaranteed, the defect that a traditional suspension bridge main cable is difficult to replace is overcome.
本发明公开了一种悬索桥更换主缆用的连接结构，包括锚碇连接结构、索鞍连接结构及吊索连接结构；所述锚碇连接结构包括索股连接板、贯穿其上下端面的预应力锚具穿索孔道、原拉杆孔和锚孔；所述索鞍连接结构包括底座、位于底座上方的新鞍体；所述吊索连接结构包括扣合在新主缆上的新索夹、与新索夹下端安装有上扁担梁、与上扁担梁通过张拉杆连接的下扁担梁。本发明公开的一种悬索桥更换主缆用的连接结构、固定结构、新主缆系统及施工方法，施工过程中不影响桥梁通车；在保证悬索桥缆索系统结构安全情况下，解决传统悬索桥主缆难以更换的弊病。
