专利汇可以提供Tension member for structure专利检索,专利查询,专利分析的服务。并且PURPOSE: To improve durability, by a method wherein a protection material formed by a steel wire, a high molecular material, is disposed on the outer periphery of a strand bundle along the axial direction of an apex part, and the protection material is covered with a covering material, e.g. a plastic materials.
CONSTITUTION: Strands 10, each formed by intertwisting a plurality of lateral wires of corrosion resistant material around a core formed by a steel, are bundled together in parallel to a plurality of main axes to form a strand bundle 11 formed approximately in a hexagon in cross section. After each of protection materials 12 is disposed in a ridge spot 11a of the bundle 11 in parallel to the axial direction of the bundle 11, a covering layer 13 is formed on an outer periphery. Even when a some substance is brought into contact therewith during the use of it for an oblique tension bridge to damage the covering layer 13 at the apex part, the protection material 12 prevents damage thereof to protect the bundle 11, resulting in the possibility to improve durability.
