ROTATION SUPPRESSION STRUCTURE OF PILE JOINT
PROBLEM TO BE SOLVED: To provide a rotation suppression structure of a pile joint capable of surely suppressing a necessary value of more of relative rotation between a first pile and a second pile, by avoiding shear force in acting on a connection pin from a key member, and avoiding torque in locally acting on the key member.SOLUTION: A rotation suppression structure comprises a key groove part 2 continuously formed on a side surface of an upper end part 6a of a first pile 6 and a side surface of a lower end part 7a of a second pile 7, and a key member 5 fitted in the key groove party 2, in a state of linking the upper end part 6a of the first pile 6 and the lower end part 7a of the second pile 7, and the key groove part 2 comprises a first groove 3 and a second groove 4, and the first groove 3 and the second groove 4 comprise contact point parts 31, 35, 41 and 45 for rotating the key member 5 while contacting with one point of side edges 51 and 52 of the key member 5 by predetermined relative rotation between the first pile 6 and the second pile 7 and contact side parts 32, 33, 36, 37, 42, 43, 46 and 47 for contacting the side edges 51 and 52 of the key member 5 in the predetermined length.SELECTED DRAWING: Figure 2
【課題】連結ピンにキー部材からせん断力が作用することを回避するとともに、回転力がキー部材に局所的に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確実に抑止することの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と第２杭７の下端部７ａとを連接させた状態で、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、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溝３と第２溝４とを有し、第１溝３及び第２溝４は、第１杭６と第２杭７との所定の相対回転によって、キー部材５の側辺５１、５２の一点と接触しながらキー部材５を回転させる接触点部３１、３５、４１、４５と、キー部材５の側辺５１、５２が所定の長さで接触する接触辺部３２、３３、３６、３７、４２、４３、４６、４７とを有する。【選択図】図２
