COATED PRESTRESSING STEEL STRAND
PROBLEM TO BE SOLVED: To provide a coated prestressing steel strand which can easily transfer distortion of an element wire and which facilitates protection of an optical fiber.SOLUTION: A coated prestressing steel strand includes: a strand in which a plurality of steel element wires are stranded together; a corrosion-proof covering that has an outer peripheral part for covering an outer periphery of the strand; an outside covering for covering an outer periphery of the corrosion-proof covering; and an optical fiber that is provided in such a manner as to follow expansion/contraction of the strand, in a location corresponding to a stranded groove of the strand, on the inside with respect to an outer peripheral surface of the outside covering.SELECTED DRAWING: Figure 1
【課題】素線の歪を伝達し易く、かつ光ファイバを保護し易い被覆ＰＣ鋼より線を提供する。【解決手段】複数の鋼製の素線をより合わせたより線と、前記より線の外周を被覆する外周部を有する防食被覆と、前記防食被覆の外周を覆う外側被覆と、前記外側被覆の外周面よりも内側で、前記より線のより溝に対応した箇所に前記より線の伸縮に追従するように設けられる光ファイバとを備える被覆ＰＣ鋼より線。【選択図】図１
