Title:
ANTICORROSION STRUCTURE FOR STEEL SHEET PILE OR STEEL PIPE SHEET PILE
Document Type and Number:
Japanese Patent JP2016008502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an anticorrosion structure for a steel sheet pile or a steel pipe sheet pile that eliminates a slant of an anticorrosive metal plate at a tightening and fixing part of an anticorrosive cover, thereby ensuring tight adhesiveness of the anticorrosion cover and providing corrosion protection for certain.SOLUTION: An anticorrosive layer 21 containing petrolatum and a cushioning layer 22 are laminated on a surface of a steel pipe sheet pile 1, for forming an anticorrosion structure 9A having a surface of the cushioning layer 22 covered with an anticorrosive metal plate 3. The anticorrosion structure includes a flat part 32 formed along an edge of a main body part 31 of the anticorrosive metal plate 3, a fixed plate 41 disposed along a rear surface side of the flat part 32 and fixed on the steel pipe sheet pile 1, an extended part of the anticorrosive layer 21 and the cushioning layer 22 laminated between the fixing plate 41 and the flat part 32, a pressing plate 43 disposed along a top surface of the flat part 32 and extended to reach a boundary between the flat part 32 and the main body part 31, a stud bolt 44 made of a non-conductive material that tightens laminated materials from the pressing plate 43 to the fixing plate 41, and a flange 452 that restricts slanting of the pressing plate 43.
