CONCRETE CONNECTING REINFORCING BAR, FIXING STRUCTURE AND CONNECTING METHOD OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a concrete connecting reinforcing bar, a fixing structure and a connecting method of a concrete structure, capable of maintaining anticorrosion performance even after the earthquake during which a large pulling force is applied, and also securing comparable fixing property as in the conventional case, and further improving workability.SOLUTION: A concrete connecting reinforcing bar, which is embedded in concrete for connecting concrete structures together, includes a steel bar body 10 and T-shaped fixing parts 11 integrally provided with the steel bar body 10 at both end parts 10a and 10b of the steel bar body 10. The concrete connecting reinforcing bar 1 is configured such that, in the steel bar body 10, the peripheral surfaces of the bar-shaped part except portions where the T-shaped fixing parts 11 are positioned, are coated with a polyethylene coating body 12 made of polyethylene resin, and the polyethylene coating body 12 is a material in which, when axial pulling force is applied to the steel bar body 10, the outer surface adhesive force against the concrete 3 becomes smaller than the inner surface adhesive force against the steel bar body 10.
【課題】地震による大きな引抜き力が作用した後でも防食性能を維持することができるうえ、従来と同等の定着性能を確保しつつ、さらに施工性の向上を図ることができる。【解決手段】コンクリート構造物同士を連結するためにコンクリート中に埋設されるコンクリート連結鉄筋であって、棒鋼本体１０と、棒鋼本体１０の両端部１０ａ、１０ｂに、棒鋼本体１０と一体で設けられるＴ字定着部１１とを有し、棒鋼本体１０のＴ状定着部１１が位置する部分を除いた棒状部周面は、ポリエチレン樹脂からなるポリエチレン被膜体１２によって被覆され、ポリエチレン被膜体１２は、棒鋼本体１０に軸方向の引抜き力が作用したときに、コンクリート３との外面付着力が棒鋼本体１０との内面付着力よりも小さくなる材料であるコンクリート連結鉄筋１を提供する。【選択図】図２
