STEEL PIPE PILE JOINT STRUCTURE
To facilitate a connection work of joint structure used for connecting steel pipe piles and connecting a pair of joints with a pin.SOLUTION: Steel pipe pile joint structure comprises a first joint 10 connected to an end of a first steel pipe pile, a second joint 20 connected to an end of a second steel pipe pile, and a pin P, and connects the first joint 10 and the second joint 20 with the pin P. The first joint 10 comprises a small diameter portion and a first fitting portion, the first fitting portion comprises a first recess and a first protrusion, the second joint 20 comprises a large diameter portion and a second fitting portion, and the second fitting portion comprises a second recess and a second protrusion. In a state where the first joint 10 is inserted into the second joint 20, the first protrusion and the second recess are fitted while the first recess and the second protrusion are fitted. A first pin with an outer diameter L2 is inserted into a first pin hole and a second pin hole, and a first gap of 0.1 to 3.0 mm is formed between an inner diameter L1 and the outer diameter L2. A second gap of 0.1 to 3.0 mm is also formed between opposing surfaces of the first fitting portion and the second fitting portion in the fitted state. Lengths of the first gap and the second gap are equal.SELECTED DRAWING: Figure 3
【課題】鋼管杭の結合に使用され、一対の接手をピン結合する接手構造の連結作業を容易にする。【解決手段】第１鋼管杭の端部に接続された第１接手１０と、第２鋼管杭の端部に接続された第２接手２０と、ピンＰとを備え、第１接手１０と第２接手２０とをピンＰで連結する鋼管杭の接手構造であって、第１接手１０は小径部と第１嵌合部とを備え、該第１嵌合部は第１凹部及び第１凸部を備え、第２接手２０は大径部と第２嵌合部とを備え、該第２嵌合部は第２凹部及び第２凸部とを備え、第１接手１０を第２接手２０へ挿入した状態で、第１凸部と第２凹部及び第１凹部と第２凸部とが嵌合状態になり、第１ピン孔と第２ピン孔へ外径Ｌ２の第１ピンが挿入され、内径Ｌ１と外径Ｌ２との間には、０．１～３．０ｍｍの第１隙間が形成され、嵌合状態の第１嵌合部と第２嵌合部の対向面間にも、０．１～３．０ｍｍの第２隙間が形成され、第１隙間と第２隙間の長さが等しい。【選択図】図３
