JOINT METHOD FOR PILE CONSTITUENT MEMBER, CONSTRUCTION METHOD OF PILE BODY, PRESS-IN DRIVER, AND CLAW MEMBER
PROBLEM TO BE SOLVED: To facilitate connection without working a pile constituent member in a complicated way, at the same time reducing a construction cost and curtailing a construction period.SOLUTION: A joint method for a pile constituent member includes: a pile constituent member arrangement step in which a top edge joint part 103 of a lower steel pipe 101A is arranged to be overlapped with a bottom edge joint part 104 of an upper steel pipe 101B; and a joint step for connecting the steel pipes 101A and 101B to each other by pressing and plastically deforming the bottom edge joint part 104 with a pressing part 22 provided for pressing a peripheral surface of the steel pipe 101. A through-hole 10 is formed through the top end joint part 103, and the pile constituent member arrangement step is followed by a pressing part positioning step in which the pressing part 22 is disposed opposite a position overlapped with the through-hole 10 of the bottom end joint part 104. In the joint step, a plastic deformation part 104A is inserted into and engaged with the through-hole 10, by plastically deforming the bottom end joint part 104 with the pressing part 22.SELECTED DRAWING: Figure 16
【課題】杭構成部材に複雑な加工を施すことなく、容易に接続することが可能であり、施工にかかるコストや工期の低減を図ることができる。【解決手段】下方鋼管１０１Ａの上端継手部１０３と、上方鋼管１０１Ｂの下端継手部１０４と、を重ねて配置する杭構成部材配置工程と、鋼管１０１の周面に対して押圧可能に設けられた押圧部２２によって下端継手部１０４を押圧して塑性変形させることにより、鋼管１０１Ａ、１０１Ｂ同士を接続する継手工程とを有し、上端継手部１０３に貫通して貫通穴１０が設けられ、杭構成部材配置工程の後において、押圧部２２を下端継手部１０４における貫通穴１０に重なる位置に対向させて配置する押圧部位置決め工程を有し、継手工程において、押圧部２２によって下端継手部１０４を塑性変形させることにより、塑性変形部１０４Ａを貫通穴１０に挿入させて係合させるようにした。【選択図】図１６
