PROBLEM TO BE SOLVED: To provide a rotation deterring structure for a pile joint that does not use a bolt, avoids rotation force to be exerted locally on a key member, and suppresses more than necessary relative rotations between a first pile and a second pile.SOLUTION: A rotation deterring structure for a pile joint includes a key groove part 2 formed continuously on a side surface of an upper edge part 6a of a first pile 6 and a side surface of a lower edge part 7a of a second pile 7, and a key member 5 fitted in the key groove part 2 across the side surface of the upper edge part 6a of the first pile 6 and the side surface of the lower edge part 7a of the second pile 7. The key groove part 2 includes a first groove formed on the side surface of the upper edge part 6a of the first pile 6 and having an upper edge surface of the first groove that faces the second pile 7 cut out, and a second groove formed on the side surface of the lower edge part 7a of the second pile 7 and having a lower edge surface of the second groove that faces the second pile 7 cut out in an almost same form as the upper edge surface of the first groove. Either or both of the first groove and the second groove has at least a part of the side surface of the first groove and the side surface of the second groove along a pile circumferential direction Y formed in a tapered shape that spreads toward a pile center in a pile plate thickness direction Z.SELECTED DRAWING: Figure 2 |
