Connector of PHC piles and connection method of PHC pile using the same

摘要

The present invention relates to a PHC pile connector which minimizes the size of the connector at the time of joining the upper and lower PHC piles, thereby providing excellent economic feasibility, quick and easy pile joint construction, and excellent structural stability, and a PHC pile connecting method using the same. The present invention PHC pile connector includes a connecting plate formed in a shape corresponding to the end shape of the PHC pile; a first fixing bolt composed of a head and a body to fix the connection plate to the upper PHC pile; and a second fixing bolt composed of a head and a body to fix the connection plate to the lower PHC pile by a fixing wedge; The first fixing bolt is configured to be in communication with the first head accommodating groove and the first head accommodating groove formed on the lower surface of the connection plate so that the head of the first fixing bolt is received in the connection plate, and the body of the first fixing bolt is passed through. A second head accommodating groove and a second head accommodating groove formed on the upper surface of the connection plate to be opened to the outside of the connection plate so as to receive the head of the first bolt fastening portion and the second fixing bolt composed of a first through hole having a width smaller than the head of Second bolt fastening parts communicating with the , consisting of second through-holes through which the head of the second fixing bolt penetrates are alternately formed, and the head of the first fixing bolt is closely fixed to the bottom surface of the first head receiving groove, and the second fixing bolt In the state that the head is inserted into the second head receiving groove, the fixing wedge inserted into the second head receiving groove through the open front surface of the second head receiving groove is caught on the lower part of the head of the second fixing bolt and the second fixing bolts are fixed
