A coupling structure of PHC(Pretentioned spun High strength Concrete) piles using a bolt is provided to facilitate the connection of the PHC file, and closely connect each PHC piles by minimizing transmitted force for the bolt and steel rod. The coupling structure of the PHC is comprised of a upper shoe(110) includes plural steel rod combining grooves(112, 212) and penetration grooves(113, 110), a upper joint cap(100) forming integrally with a upper part enforcement band(120), and a lower part joint cap(200) forming integrally with the lower part enforcement band. The upper part enforcement band forms watertight box with square section shape. The PHC piles forms integrally the upper joint cap and lower joint cap in both ends. |
