A joint apparatus of a concrete pile and a steel pipe pile is provided to transfer piling force to the ground and to prevent a lower pile and a connector from being damaged and deformed by connecting the concrete pile with the steel pipe pile by connecting members and piling the two piles in the ground. A joint apparatus of a concrete pile(2) and a steel pipe pile comprises lower and upper disks(22,21), connecting members, annular rings(25), and bolts(26). The lower disk is formed with through holes(22a) at position corresponding to a plurality of PC nuts(2a) which are placed at the upper part of the concrete pile. The upper disk is welded with upper steel pipe piles(3). The connecting members, which are integrated between the upper and lower disks, have center pipes(23) having bolt holes. At least a part of the annular rings is connected with edges of the disks and is vertically cut. The bolts are screwed with the bolt holes of the center pipe. The connecting members are vertical plates extended with a predetermined gap between the upper and lower disks. |
