COATING CORROSION PREVENTION STRUCTURE FOR STEEL SHEET PILE, AND PROTECTIVE COVER MOUNTING TOOL
PROBLEM TO BE SOLVED: To provide a coating corrosion prevention structure and a protective cover mounting tool, with which it is easy to mount a protective cover that protects a surface of a coating corrosion-proof steel sheet pile and it is unlikely that the protective cover falls off, and which can stably demonstrate anticorrosion performance for a long period.SOLUTION: A protective cover mounting tool 5A has a support base material 5 fixed on the surface of a steel sheet pile 20, a buried part 6A buried in a fixing hole 50, and a protruding part 6B. The protruding part 6B comprises a bolt 6 protruding from the surface of a protective cover 4, and a nut 7 that is screwed to the protruding part 6B outside the surface of the protective cover 4. The bolt 6 is fixed to the support base material 5 by tightening of the buried part 6A due to an opening peripheral edge portion of the fixing hole 50, which is plastic-deformed by a press-fit of the bolt 6.SELECTED DRAWING: Figure 3
【課題】被覆防食された鋼製矢板の表面を保護する保護カバーの取り付けが容易で、且つ保護カバーの脱落が起こり難く、防食性能を長期間安定的に発揮することができる被覆防食構造及び保護カバー取付け具を提供すること。【解決手段】保護カバー取付け具５Ａは、鋼製矢板２０の表面に固定された支持基材５と、固定孔５０に埋設された埋設部６Ａ及び突出部６Ｂを有し、突出部６Ｂが保護カバー４の表面から突出しているボルト６と、保護カバー４の表面より外側にて突出部６Ｂに螺合されているナット７とを具備する。ボルト６は、該ボルト６の圧入によって塑性変形した固定孔５０の開孔周縁部による埋設部６Ａの締め付けによって、支持基材５に固定されている。【選択図】図３
