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
