CONCRETE REINFORCEMENT BAR WITH IRREGULARITY
To provide a concrete reinforcement bar to which adhesive stress between a concrete structure and itself and deflection tendency (elastic coefficient) are balanced.SOLUTION: A concrete reinforcement bar 10 comprises a wire 20 impregnated with resin 22 in a bundle of a plurality of continued carbon fibers 21, and covering materials 30A, 30B wound around a peripheral surface of the wire 20. Each of the covering materials 30A, 30B comprises a twisted structure produced by twisting a plurality of PET yarns 31. The PET yarns 31 are twisted in a twist angle range of 1.0 to 4.5°.SELECTED DRAWING: Figure 3
【課題】コンクリート構造物との間の付着応力度およびたわみやすさ（弾性係数）のバランスがとられたコンクリート補強筋を提供する。【解決手段】コンクリート補強筋１０は，複数本の連続する炭素繊維２１の束に樹脂２２を含浸させた線材２０，および上記線材２０の外周面に巻き付けられた被覆材３０Ａ，３０0Ｂを備えている。被覆材３０Ａ，３０Ｂは，それぞれが，複数本のＰＥＴ糸３１に撚りを加えた撚線構造を備えている。ＰＥＴ糸３１は撚り角度１.０～４.５°の範囲で緩く撚られる。【選択図】図３
