CORROSION PROTECTION STRUCTURE OF IRON REINFORCED CONCRETE STRUCTURE AND CORROSION PROTECTION METHOD
To suppress damage to an iron reinforced concrete structure to minimum by exhibiting an anticorrosion effect by non-contact with a steel bar present inside of the iron reinforced concrete structure, and to reduce installation cost and management cost.SOLUTION: There are provided a conductive member 30 wound around a circumference of an iron reinforcement (main reinforcement 10) present inside of an iron reinforced concrete structure 50, and a power source device 40 supplying an alternate current to the conductive member 30. The conductive member 30 is spirally wound around an iron reinforcement (main reinforcement 10). Further, the iron reinforcement (main reinforcement 10) is divided into a plurality of divisions in an axis direction, and the conductive member 30 may be wound for every division respectively. Furthermore, the conductive member 30 may be wound around an outer periphery part of the iron reinforced concrete structure 50, or may be wound around an outer periphery part of the iron reinforcement (main reinforcement 10) itself. And, an electric current cancelling a corrosion current is generated on a superficial part of the iron reinforcement (main reinforcement 10) by an action of electromagnetic induction to perform the corrosion protection of the iron reinforcement (main reinforcement 10).SELECTED DRAWING: Figure 1
【課題】 鉄筋コンクリート構造物の内部に存在する鉄筋と非接触で防食効果を発揮させることにより、鉄筋コンクリート構造物の損傷を最低限に抑えるとともに、施工コストや管理コストを低減する。【解決手段】 鉄筋コンクリート構造物５０の内部に存在する鉄筋（主筋１０）の周囲に巻き付けた導電部材３０と、導電部材３０に交番電流を供給する電源装置４０とを備える。導電部材３０は、鉄筋（主筋１０）の周囲に螺旋状に巻き付ける。また、鉄筋（主筋１０）を軸方向に複数の区間に区分して、区間毎にそれぞれ導電部材３０を巻き付けてもよい。また、導電部材３０は、鉄筋コンクリート構造物５０の外周部に巻き付けてもよいし、鉄筋（主筋１０）自体の外周部に巻き付けてもよい。そして、電磁誘導の作用により鉄筋（主筋１０）の表皮部分に腐食電流を打ち消す電流を発生させて、当該鉄筋（主筋１０）の防食を行う。【選択図】図１
