Main cable splay saddle for self-anchorage suspension bridge

The invention discloses a main cable splay saddle for a self-anchorage suspension bridge. The main cable splay saddle comprises a lower saddle body, an upper saddle cover, a clamping cover and a base plate. A plurality of partition plates are arranged in guide slot ways in a rear saddle body of the lower saddle body and used for separating main cable strands in different columns. The upper saddle cover and the rear saddle body form a cable strand dispersing section, and the main cable strands are vertically arranged. The upper saddle cover and a middle saddle body form a cavity section. The shape that the main cable is in circular transition in a clamping section and the cable strands in the cable strand dispersing section are vertically arranged is ensured. The clamping cover and a front saddle body form the clamping section, and clamping force and anti-slid frictional resistance are provided. The base plate is fixed to the lower portion of the lower saddle body and used for fixing the whole main cable strand dispersing structure. The main cable strand dispersing structure has the advantages of both the splay saddle and a splay sleeve. A single space cable strand can be dispersed at different angles in the transverse and vertical directions, and the cable strands on the same column in the main cable can be anchored on a stiffening beam anchorage face in the same row, so that the vertical size of the anchorage face is reduced, anchorage is achieved by means of bridge transverse width so that the height of the stiffening beam can be reduced, main cable strands in the cable saddle can be easily and conveniently constructed, the installation precision of the cable strands can be controlled, and the main cable splay saddle can be applicable to the large-span anchorage type suspension bridge and has high economic benefits.
