ROTATION DETERRING STRUCTURE FOR PILE JOINT
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
【課題】ボルト等を使用せず、キー部材に局所的に回転力が作用することを回避して、第１杭と第２杭との必要以上の相対回転を抑止できる杭継手の回転抑止構造を提供する。【解決手段】第１杭６の上端部６ａの側面と第２杭７の下端部７ａの側面とに連続して形成されるキー溝部２と、第１杭６の上端部６ａの側面と第２杭７の下端部７ａの側面とに亘ってキー溝部２に嵌入されるキー部材５とを備え、キー溝部２は、第１杭６の上端部６ａの側面に形成され、第２杭７に対向する第１溝上端面が切り欠かかれた第１溝と、第２杭７の下端部７ａの側面に形成され、第２杭７に対向する第２溝下端面が第１溝上端面と略同一形状で切り欠かれた第２溝とを有し、第１溝及び第２溝の何れか一方又は両方は、杭円周方向Ｙの第１溝側面及び第２溝側面の少なくとも一部が、杭板厚方向Ｚで杭中心方向に向けて拡がるテーパ状に形成される。【選択図】図２
