INTERNAL ANTICORROSION METHOD OF STRUCTURAL STEELWORK HAVING SPACE INSIDE
To provide an internal anticorrosion method of a structural steelwork having a space inside, capable of facilitating a construction work for imparting an anticorrosive effect to an existing structural steelwork.SOLUTION: A first opening 24 and a second opening 28 are provided on a side wall of a strut 20, and an anode material 10 formed by arranging water retention fibers 14 on the outer periphery of a metal rod 12 having a lower potential than the strut 20 is arranged inside the strut 20 from the first opening 24, and fixed in the state where conduction between the metal rod 12 and the strut 20 through the second opening 28 is carried out, and the first opening 24 is blocked with a steel sheet 32.SELECTED DRAWING: Figure 7
【課題】既設の鋼構造物に対して防食効果を付与する工事を簡易なものとすることのできる内部に空間を有する鋼構造物の内部防食方法を提供する。【解決手段】支柱２０の側壁に第１開口部２４と第２開口部２８を設け、支柱２０よりも卑な電位を有する金属棒１２の外周に保水性繊維１４を配置した陽極材１０を第１開口部２４から支柱２０の内部に配置すると共に、第２開口部２８を介して金属棒１２と支柱２０との導通を図った状態で固定し、第１開口部２４を鋼板３２で塞ぐことを特徴とする。【選択図】図７
