摘要： PROBLEM TO BE SOLVED: To provide a different diameter pile coupling which eliminates the need for welding work on an execution site, and which can combine a first pile member of a large diameter with a second pile member of a small diameter easily and securely by screw-fastening work.
SOLUTION: The different diameter pile coupling, which is used for combining the upper pile member 8 of a large diameter and the lower pile member 9 of a small diameter, is provided with a first coupling part 12 and a second coupling part 13. The first coupling part 12 is combined with the upper pile member 8, and the second coupling part 13 is combined with the lower pile member 9. Then the first and second projections 20, 21 are provided on each of the inner peripheral surfaces of the first and second engagement ends 18, 19 of the first and second coupling parts 12, 13, and the first and second engagement ends 18, 19 are confronted with each other. Then a fastening member 15 is fastened by a bolt 14 in a state that the first and second projections 20, 21 are caught in the fastening member 15. Thus, the first coupling part 12 and the second coupling part 13 of the different diameter pile coupling can be engaged with each other. The first combination end 16 of the first coupling part 12, which is combined with the upper pile member 8, has a larger diameter than the second combination end 17 of the second coupling part 13, and the second combination end 17 is combined with the lower pile member 9.
