Description of the Related Art A main cable of a suspension bridge is manufactured by bundling a required number of high-strength galvanized steel wires having a circular cross section. Conventionally, in order to prevent such a cable from being corroded, as shown in FIG. 2, a paste-like rust-preventive paint 2 is applied to the outermost peripheral surface of the cable 1 and then a zinc-plated wrapping wire having a circular cross section. 5 was wrapped closely and then an anticorrosive coating 6 was applied thereon. In this anticorrosion method, the inside of the cable is shielded from the external corrosive environment by the coating of the paste-like anticorrosive paint 2, the circular wrapping wire 5 and the anticorrosion paint 6, and the intrusion of water into the cable is prevented. It is intended to prevent corrosion.

するものである。However, according to the above-described anticorrosion method which has been conventionally applied, the circular wrapping wire 5 wound tightly after a long period of time due to the expansion and contraction of the cable due to the rocking and temperature changes. The outermost anticorrosive coating 6 is likely to be displaced, and the outermost anticorrosive paint 6 has a low elongation ability. As a result, corrosion factors such as water and salt easily enter from cracks, which is not preferable in terms of anticorrosion. Therefore, even if the expansion and contraction motion due to the cable swing and temperature change is applied for a long time, if the defect such as cracking of the anticorrosion coating can be prevented, it is surely longer than ever before,
The main cable of the suspension bridge can be protected from corrosion. SUMMARY OF THE INVENTION An object of the present invention is to provide a cable anticorrosion method capable of preventing defects such as cracks in an anticorrosion coating, even when a telescopic movement due to cable sway or temperature change is applied for a long time. .

法が有効である。Embodiments of the present invention will be described below. FIG. 1 is a sectional view of a cable showing a cable corrosion protection method of the present invention. The main cable of the suspension bridge is manufactured by bundling a required number of galvanized high-strength steel wires 1 having a circular cross section. In the present invention, a paste-like rust preventive paint 2 is applied to the outermost surface of the cable. This paste-like rust preventive paint prevents water from entering the cable. As the rust preventive paint 2, a drying oil containing an aluminum phosphate pigment, a drying oil containing an alkylbenzene sulfonic acid,
It is preferable to use a drying oil containing a rust-preventive pigment having the rust-preventing property of zinc or iron, such as a drying oil containing sodium vanadate. The application amount of the rust preventive paint 2 is preferably about 2 kg / m 2 in order to apply it evenly to the surface of the cable.
Next, after the paste-like rust-preventive paint 2 is applied, a substantially S-shaped wrapping wire 3 having wedge-shaped engaging portions (3a, 3b) formed on both left and right sides from above is wrapped adjacently. The wire is wound with the engagement portion in close contact with the wire. With the use of the wrapping wire, the adjacent wires are engaged, so that it is less likely to be displaced and no gap is generated between the wrapping wires. Next, a flexible coating 4 is applied to the outside. The paint used for this coating 4 can be selected from epoxy resin paints, urethane resin paints, and fluororesin paints.
At less than 1% at ℃, the flexibility increases with temperature and is about 3% at room temperature (20%). In contrast, the flexible paint used in the present invention has an elongation at 0 ° C. of 1% or more and 100% or more.
Less than 5% and less than 100% at room temperature (20 ° C.).
If the elongation is less than 5% at 20 ° C., the coating tends to crack due to the stretching movement, and if it is more than 100%, the cohesive strength of the coating film is undesirably reduced. Paint 4
Has excellent waterproofing and corrosion factor intrusion prevention properties, as well as excellent adhesion with galvanized mild steel wire,
It is necessary to have excellent weather resistance and to have flexibility. For this reason, the paint used for the paint 4 of the present invention is an epoxy resin-based undercoat having good adhesion to zinc, an epoxy resin-based undercoat having excellent waterproofness and compatibility with the undercoat and topcoat, and urethane having excellent weather resistance. Resin-based paints or fluororesin-based paints can be used. It is preferable that the total thickness of the undercoat, intermediate coat, and top coat is 0.15 mm or more. In addition, in order to make the paint flexible, a flexible material is used for the base resin of the paint, or
It is effective to lower the crosslink density of the resin or to add a rubber material.
