INSTALLATION METHOD OF GALVANIC ANODE MATERIAL
To provide an installation method of a galvanic anode material which allows for acquisition of electrochemical corrosion proof structure of a concrete structure enabling a galvanic anode material of a punctual anode type to be easily installed, a concrete to be repaired after installation of the galvanic anode material, and the galvanic anode material to be easily replaced.SOLUTION: An anchor hole 4 is provided on a bottom face of a construction hole 1H which is drilled according to a position of a steel material being a corrosion prevention object on a concrete surface of a concrete structure in which the steel material being the corrosion prevention object is embedded, then a metallic anchor 3 is installed on the anchor hole in such a way that the metallic anchor contacts the steel material being the corrosion prevention object, then an electrochemical corrosion prevention unit 10 comprising: a plate-shaped galvanic anode material 13; a cover 15 forming a space for three-dimensionally surrounding the galvanic anode material, by a concrete surface and the inner surface of the cover 15; and a metallic rod material having a support 11b supporting the galvanic anode material and the cover, and an upper end which can be detachably fitted to the anchor, is fastened to the anchor 3 through the upper end and thus, the steel material being the corrosion prevention object and the galvanic anode material are in electrical contact with each other through the metallic anchor and the metallic rod material.SELECTED DRAWING: Figure 1
【課題】点状陽極方式の流電陽極材の設置、流電陽極材の設置後のコンクリートの修復、および流電陽極材の交換が容易なコンクリート構造物の電気化学的防食構造を得ることができる、流電陽極材の設置方法の提供。【解決手段】防食対象鋼材が埋設されたコンクリート構造物のコンクリート表面に防食対象鋼材の位置に合わせて削孔した施工孔１Ｈの底面にアンカー孔４を設け、このアンカー孔に金属製アンカー３を防食対象鋼材と接触するように設置し、板状の流電陽極材１３と、この流電陽極材をコンクリート表面と自らの内面によって立体的に包囲する空間を形成するカバー１５と、流電陽極材ならびにカバーを支持する支持部１１ｂおよびアンカーに着脱可能な上端部を有する金属製棒材とを有する電気化学的防食ユニット１０を上端部を通じてアンカーに固着することによって、防食対象鋼材と流電陽極材とを、金属製アンカーおよび金属製棒材を通じて電気的に接続する。【選択図】図１
