Abstract

The invention discloses an anti-slip cable saddle structure for suspension bridges. The anti-slip cable saddle structure comprises a saddle. The bottom of a trough of the saddle is provided with at least one longitudinal partition parallel to trough walls. At least one discontinuous clamp plate layer is arranged between each two adjacent longitudinal partitions or between each longitudinal partition and the corresponding trough wall. Each discontinuous clamp plate layer is formed by linking at least four tangential clamp plates in the longitudinal direction. Besides the bottom of the trough and the sidewalls all providing effective friction, the added tangential clamp plates and longitudinal partitions provide effective friction, so that slip resistance is greatly improved; slipping between a main cable and the trough can be prevented; an effective solution is provided for cable saddle structures of small side- and middle-span ratio suspension bridges or multi-pylon multi-span suspension bridges, and overall rigidity, wind resistance and bearing capacity of the bridges are improved.

Description

technical field [0001] The invention belongs to the technical field of suspension bridges, and in particular relates to an anti-skid cable saddle structure of a suspension bridge. Background technique [0002] In the structure of the suspension bridge, the cable saddle is set on the top of the main tower to fix and support the main cable. The cable saddle is passed to the main tower. Due to the functional characteristics of the cable saddle, it is required that there is no relative displacement between the cable saddle and the main cable. Displacement trend; when under dynamic load, there will be a difference in the tension of the main cable on the two sides outside the cable saddle, resulting in a displacement trend of the main cable in the cable saddle. This displacement trend will cause the main cable to be divided by other components of the suspension bridge. Damage, damage the structural stress of the main cable, and then affect the strength of the main cable. [000...
