REINFORCEMENT CORROSION PREVENTION STRUCTURE AND REINFORCEMENT CORROSION PREVENTION METHOD OF CONCRETE STRUCTURE
To provide a reinforced corrosion prevention structure and a reinforced corrosion prevention method in which an anode member is adhered to a structure through mortar or cement paste and reinforcing fibers can be firmly and efficiently stuck to a concrete structure.SOLUTION: A belt-like anode member 11 is stuck on a cement paste layer 15 applied on the surface of a concrete structure 1, and a reinforcing fiber sheet 12 formed by weaving fibers continuous in two directions into a belt shape is stuck so as to cover the anode member. In the reinforcing fiber sheet, a reinforcing fiber 12a continuously reinforcing the concrete structure in the axial direction of the anode member is woven more coarsely in a region A which is overlaid on the anode member, than the region B, which is the side of the anode member. The modulus of elasticity of a lateral fiber 12b of the reinforcing fiber sheet is smaller than that of the reinforcing fiber and is stuck in a state where tensile force is introduced in the lateral direction. Then, a DC voltage is applied between the anode member and the reinforcing bar 14 embedded in the concrete structure.SELECTED DRAWING: Figure 3
【課題】陽極部材がモルタル又はセメントペーストを介して構造物に密着するとともに補強繊維をコンクリート構造物に強固に効率よく貼り付けることができる補強防食構造及び補強防食方法を提供する。【解決手段】コンクリート構造物１の表面に塗布されたセメントペースト層１５の上に帯状の陽極部材１１を貼り付け、該陽極部材を覆うように、２方向に連続する繊維を帯状に織った補強繊維シート１２を貼り付ける。補強繊維シートは、陽極部材の軸線方向に連続してコンクリート構造物を補強する補強繊維１２ａが、陽極部材に重ねられる領域Ａでは、陽極部材の側方となる領域Ｂより粗に織られたものとする。補強繊維シートの横方向繊維１２ｂは補強繊維より弾性係数が小さいものとし、横方向に引張力が導入された状態で貼り付ける。そして、上記陽極部材とコンクリート構造物に埋め込まれた鉄筋１４との間に直流電圧を印加する。【選択図】図３
