Composite carbon fiber stranded inhaul cable

Abstract

The invention discloses a composite carbon fiber stranded inhaul cable which comprises a stranded cable body and a large sheath, wherein the large sheath is arranged on the outer surface of the stranded cable body and used for protecting the stranded cable body, the stranded cable body comprises a steel stranded cable and a composite carbon fiber stranded cable, the composite carbon fiber stranded cable comprises side steel wires, a carbon fiber center wire, an epoxy coating and a PE sleeve, the side steel wires and the carbon fiber center wire are arranged together in a twisted mode, and the PE sleeve is arranged on the outer surface of the composite carbon fiber stranded cable and used for protecting the composite carbon fiber stranded cable. According to the invention, the carbon fiber center wire and the six side steel wires are twisted together, the carbon fiber center wire is well protected by the six side steel wires, the six side steel wires can resist external shearing force, and the innovative structure well solves the problem that engineering application is difficult to popularize due to insufficient shearing resistance of carbon fibers.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a composite carbon fiber stranded cable. Background technique [0002] The research on carbon fiber cables at home and abroad started relatively early, nearly 20 years ago, but there has been no large-scale promotion and application. There is no domestic bridge engineering application, and only a few cables are used in a bridge project abroad. Carbon fiber cables. There are roughly three reasons for this situation. First, the cables are theoretically only subjected to axial force, but the load conditions of the bridge are complex, and the actual forces on the cables are also relatively complicated. The carbon fiber cable structure has always been based on the parallel steel cable. For the cable body structure, because the carbon fiber reinforcement itself is not shear resistant, the bridge designer has been worried about the safety of the cable; the second is that the anchorage s...
