To provide a method for preventing corrosion of a press-fit butt-type flange joint which can be repaired even if a material filled in a clearance portion is deteriorated with age, while preventing corrosion from the clearance portion formed between an inner surface of a main column material of a press-fit portion of the press-fit butt-type flange joint and a tapered portion of a tip of a hub portion.SOLUTION: A method for preventing corrosion of a press-fit butt-type flange joint attached to an end of a main column material of a steel pipe steel tower comprises the steps of: applying an adhesive in a clearance portion formed between an inner surface of the main column material of a press-fit portion and an outer surface of a hub portion; affixing a sheet-like protective material to an application surface of the adhesive; and filling the remaining recess of the clearance portion with the adhesive to fill the clearance portion.SELECTED DRAWING: Figure 13
【課題】 圧入突合せ型フランジ継手の圧入部の主柱材内面とハブ部先端のテーパー部との間に形成される隙間部からの発錆を防止するとともに、隙間部に充填した材料が経年劣化しても補修可能な圧入突合せ型フランジ継手の防錆方法を提供すること。【解決手段】 鋼管鉄塔の主柱材端部に取り付けられた圧入突合せ型フランジ継手において、圧入部の主柱材内面とハブ部外面との間に形成される隙間部内に接着剤を塗布する工程と、前記接着剤の塗布面にシート状の保護材を貼り付ける工程と、隙間部の残りの凹部に接着剤を充填して隙間部を埋める工程とを備える。【選択図】図１３
