CORROSION PREVENTION STRUCTURE OF STEEL PIPE SHEET PILE AND PRESSER PLATE
To provide a corrosion prevention structure of a steel pipe sheet pile which is excellent in adhesion of a corrosion prevention layer to an uneven surface of a steel pipe sheet pile and can effectively protect corrosion of the uneven surface, and a presser plate usable in the corrosion prevention structure.SOLUTION: Fixing means 20, which is arranged in a groove part 32 of a steel pipe sheet pile 3 and presses a corrosion prevention body part 10 against the steel pipe sheet pile 3 side and fixes the corrosion prevention body part 10, includes a presser plate 21 contacting the surface of the corrosion prevention body part 10, a bolt 22 and a nut 23. A pair of bent parts 210 on both sides of the presser plate 21 are made to overlap the corrosion prevention body part 10 provided on the outer peripheral surface 1a of a steel pipe body 1, and a portion 211 sandwiched between the pair of bent parts 210 in the presser plate 21 is made to overlap the corrosion prevention body part 10 provided on an outer surface 2a of a joint 2 in the state where the bolt 22 penetrates therethrough and the portion 211 is pressed against the joint 2 side. When the nut 23 is removed from the bolt 22 and a pressed state of the presser plate 21 is released, the portion 211 is curved in a direction separated from the joint 2 by spring back.SELECTED DRAWING: Figure 2
【課題】鋼管矢板の凹凸表面に対する防食層の密着性に優れ、該凹凸表面を効果的に暴防食し得る、鋼管矢板の防食構造及び該防食構造に使用可能な押さえ板材を提供すること。【解決手段】鋼管矢板３の溝部３２に配され、防食本体部１０を鋼管矢板３側に押さえつけて固定する固定手段２０は、防食本体部１０の表面に接触する押さえ板材２１と、ボルト２２及びナット２３とを含む。押さえ板材２１の両側部の一対の折り曲げ部２１０が、鋼管本体１の外周面１ａに設置された防食本体部１０に重ねられ、押さえ板材２１における該一対の折り曲げ部２１０に挟まれた部分２１１が、ボルト２２が貫通され継手２側に押圧された状態で、継手２の外面２ａに設置された防食本体部１０に重ねられている。ナット２３をボルト２２から外して押さえ板材２１の押圧状態を解除すると、前記部分２１１がスプリングバックにより継手２から離れる方向に湾曲する。【選択図】図２
