Description

Technical Field

[0001] The present technology relates to the technical field of suspension bridges, and in particular to an anti-slip cable clamp with a replaceable friction plate. Background Art

[0002] A suspension bridge is a bridge whose main load-bearing superstructure is made of cables suspended from towers and anchored on both sides. The main load-bearing component of a suspension bridge is the suspension cable, which mainly bears tension and is generally made of steel with high tensile strength (steel wire, steel cable, etc.). The cable clamp is an important component for connecting and fixing the suspension cable to the main cable. The cable clamp is used to hold the main cable tightly. However, due to the natural sag of the main cable between the bridge tower and the ground anchor, the cable clamp often slips under the influence of static and dynamic loads such as beam weight, wind vibration, vehicles, and the inclination force component. This not only changes the stress condition of the bridge, but also accelerates the damage of related components, thereby posing a certain safety hazard to the bridge. Summary of the Invention
