Suspension bridge main cable anti-corrosion and multi-performance material composite fire-resistant protection combined system and construction method
The invention relates to a suspension bridge main cable anti-corrosion and multi-performance material composite fire-resistant protection combined system and a construction method, and belongs to the technical field of bridge fire resistance and corrosion resistance. Comprising a main cable, a plurality of cable clamps are arranged on the main cable, and the cable clamps are arranged at intervals in the length direction of the main cable; the outer surface of the main cable is provided with a fire-resistant and anti-corrosion layer, and the fire-resistant and anti-corrosion layer comprises a sealing inner layer, a fire-resistant protective layer and a sealing outer layer which are arranged from inside to outside. And a circular seam sealing layer is arranged at the joint of the main cable and the cable clamp. The fire-resistant protective layer comprises a heat-insulation flame-retardant layer, a reflection fire-resistant layer is arranged on the periphery of the heat-insulation flame-retardant layer, and a bonding layer is arranged between the reflection fire-resistant layer and the heat-insulation flame-retardant layer for fixed connection. The anti-corrosion fireproof door has good anti-corrosion performance, the fire resistance can be greatly improved and guaranteed, meanwhile, construction is convenient, the economic performance is good, the whole structure system is efficient, durable and good in decoration performance, and remarkable social and economic benefits are achieved.
