Problems solved by technology

[0003] Most of the existing cable bridges are made of metal materials. Although they have good fire resistance and fire resistance, they are easily corroded by water or other substances and have poor corrosion resistance. Some are made of new materials such as glass fiber reinforced plastics. Although they have good mechanical properties and corrosion resistance Strong performance, but easy to burn, poor fire resistance

Abstract

The invention discloses a composite fireproof anticorrosive cable bridge. The composite fireproof anticorrosive cable bridge comprises a basic material layer, a fireproof layer, an anticorrosive layerand a sizing material layer, wherein the outer part of the basic material layer is coated with the sizing material layer; the fireproof layer is adhered to the sizing material layer; the outer part of the fireproof layer is coated with the sizing material layer; the anticorrosive layer is adhered to the outer part of the sizing material layer. According to the composite fireproof anticorrosive cable bridge disclosed by the invention, a multilayer reinforced section structure is adopted; the fireproof layer is arranged on the outer part of the basic material layer, and the anticorrosive layeris arranged at the outer part of the fireproof layer, so that the strength of the cable bridge is higher, bearing capacity is higher and the distorsion and deformation resistance is higher while the fireproof property and corrosion resistance of the cable bridge are improved, and the service life of the cable bridge is effectively prolonged.
