There is a parallel wire strand (PWS) method. PW
The S method is a method in which a required number of galvanized high-strength steel wires or coated galvanized high-strength steel wires are tightly bundled and a plurality of PWSs having both ends fixed are bundled to construct a main cable. This construction method has an excellent advantage that the construction period can be greatly shortened as compared with the conventional air spinning (AS) construction method in which the wires are laid one by one.

ル最外層を防食被覆するのが一般的である。In laying a main cable of a suspension bridge, a plurality of bundled PWSs squeeze the surface and keep the cross-sectional shape of the cable circular, and then lay a cable band every ten and several meters, and hang the rope. Erected,
After the stiffening girder is installed and closed, it is common to finally coat the outermost layer of the cable with an anticorrosion by a wire wrapping method or a plastic wrapping method.

りケーブルを被覆する方法である。The wire wrapping method is a method adopted in most large suspension bridges in Japan. After coating the entire surface of the cable with a rust preventive paste, a 3 to 5 mm diameter galvanized mild steel wire is closely wound and This is a method of applying anticorrosion coating on top to prevent corrosion. The plastic wrapping method is
For example, as disclosed in JP-B-45-24304, a method of coating a cable with glass fiber reinforced plastic (FRP) or the like.

防食を行っている。Since the suspension bridge is used for a long period of several decades after completion, the corrosion prevention of the main cable supporting the bridge is very important because it affects the life of the bridge. For this reason, the PWS used for the construction of conventional main cables
Is coated with zinc or zinc-plated for each element wire, and then coated with a thickness of several μm. After bundling PWS, the cable is isolated from the outside by wire wrapping method or plastic wrapping method. To prevent corrosion.

ととなる。[0007] As the suspension bridge grows in length, it takes several years for the construction work to be exposed to the outdoors for a long period of time, and the conventional PWS is insufficient in corrosion protection during the construction work. In addition, after the completion of the cable, if a defect occurs in the outer layer of the cable due to the shaking or vibration of the cable, it is not possible to isolate the inside of the cable from the outside environment at the defect, so the wires near the defect will cause corrosion in the outside environment.

り的確に防食できる。FIG. 1 is a sectional view of a suspension bridge main cable according to the present invention. Steel wire is galvanized or galvanized, and then a number of micrometer-thick anticorrosion-coated elemental wires 1 are bundled together in a dense bundle. A PWS 2 is covered with a coating layer 3 on the outer periphery, and a large number of PWSs are coated on the outer periphery. After the main bundling, a spacer 4 is provided so that the cross-sectional shape of the bundled cables is maintained in a circular shape, and the outer layer of the spacer 4 is coated with an anticorrosion coating 5 by a wire wrapping method or a plastic wrapping method. PWS
By applying the coating layer 3 on the outer periphery of 2, the PWS can be shielded from the environment exposed to the outdoors during erection work to prevent corrosion, and even after the cable is completed, even if a defect occurs in the cable outer layer, the coating layer Since the strands are isolated from the outside world, the strands can be protected from corrosion, and the suspension bridge main cable can be accurately protected over a long period of time.
