Support-type corner cable saddle

Abstract

The invention discloses a support-type corner cable saddle and belongs to the technical field of bridges. The support-type corner cable saddle comprises saddle bodies and a support. The saddle bodiesintegrate the bearing function of the main cable saddle body and the divergence function of the vice cable saddle body. The support comprises an upper supporting plate and a lower supporting plate which are oppositely arranged, and the upper supporting plate is connected with bottom plates of the saddle bodies. A circular-arc-shaped concave face is arranged in the middle of the side, close to thelower supporting plate, of the upper supporting plate, and a circular-arc-shaped convex face matched with the circular-arc-shaped concave face is arranged in the middle of the side, close to the uppersupporting plate, of the lower supporting plate. When a main cable generates the cable force difference at a supporting section and a divergence section, the circular-arc-shaped convex face can rotate around the circular-arc-shaped concave face, the upper supporting plate and the saddle bodies can move in the extending direction of a cable bearing groove to adjust the positions of the saddle bodies, thus cable force of the main cable at the supporting section and the divergence section reaches balance at the new position, the structure is simple, and mounting and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a support type corner cable saddle. Background technique [0002] Corner saddles are mostly used in single tower suspension bridges. Single-tower suspension bridges are mostly found in alpine and canyon areas with a large difference in terrain between the river banks on both sides. The main tower structure is canceled on the bank side of the river, and the functions of the main cable saddle and the loose cable saddle are realized at the same time by using the corner cable saddle. Since the setting of the main tower on one side is canceled, the construction height of the suspension bridge is reduced, and the engineering amount is greatly reduced. Save cost and shorten construction period. [0003] The current corner cable saddle includes two parts: saddle body and saddle seat. The saddle body includes a bottom plate and a body arranged on the bottom plate. There are multiple sid...
