Abstract

The invention discloses a double-direction movable stay-cable anchoring device for a saddle type cable tower zone of a low tower cable-stayed bridge. The double-direction movable stay-cable anchoring device comprises a bottom plate and a double-direction anchoring unit, wherein the double-direction anchoring unit comprises an upper sleeve plate, a lower sleeve plate and fusiform clamping pieces; the bottom plate is fixedly connected with a bridge tower, the upper sleeve plate and the lower sleeve plate are connected through compression bolts, and the double-direction anchoring unit is connected with the bottom plate through the compression bolts; sleeve holes allowing cables to penetrate through are formed in the bottom plate, the upper sleeve plate and the lower sleeve plate, and the fusiform clamping pieces are arranged between the sleeve hole of the upper sleeve plate and the sleeve hole of the lower sleeve plate. Through the adoption of the double-direction movable stay-cable anchoring device disclosed by the invention, the cable can be anchored in two directions and is movable, when moving in two directions, the cable can generate sliding resistance force through the cable force, and after the compression bolts are loosened, the anchoring system can be movable and demountable.

Description

technical field [0001] The invention belongs to the technical field of cable-tower anchoring of short-tower cable-stayed bridges, and relates to a two-way movable cable-stayed cable anchorage device in a saddle-type cable-tower area of ​​a short-tower cable-stayed bridge. Background technique [0002] Compared with conventional cable-stayed bridges, the cables of short-tower cable-stayed bridges have relatively less force and contribution to the overall structure. Therefore, the cables on both sides of the bridge tower can be made continuous, directly passing through the two ends of the bridge tower and then anchored in the on the main beam. The connection between the cable and the bridge tower needs to be anchored to prevent the movement between the cable and the bridge tower, so that the bridge tower can participate in the structural force. When the cable forces on both sides of the bridge tower are unbalanced, there is a tendency to slide between the stay cable and the b...
