PROBLEM TO BE SOLVED: To provide a joint structure, and a joint method of a precast pile and a superstructure, for reducing cost, and shortening a construction period, by easily and surely arranging a transmission stress reducer. SOLUTION: This joint structure of the precast pile and the superstructure, interposes the transmission stress reducer 4 for reducing the transmission of stress between the hollow precast pile 1 and the superstructure 3 formed above the precast pile 1. A disk-like cover part 5 is put on the upper end of a pile head part 2 of the precast pile 1. A stud bolt 6 is erected on an upper surface of the cover part 5, and a rib part 7 fitted in the pile head part is suspended by a bottom surface of the cover part 5. The transmission stress reducer 4 is fixed to the stud bolt 6, and is fixed to an anchor material 15 projecting downward from an under surface of the superstructure 3. COPYRIGHT: (C)2005,JPO&NCIPI
