JOINT STRUCTURE OF PC PILE AND JOINT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a joint device of PC piles without requiring any welding work when the PC piles are to be connected with simple structure. SOLUTION: A joint device is equipped with openings 2b provided at an interval in the circumferential direction, metal cylindrical thin plates 2 having both open ends, fixing sections capable of interlocking a pair of interlock sections 6 opposed to both sides of the portal open ends and monolithically projected inward and the ends of PC steel bars 4 and approximately C-shaped joint metal fixtures 5 fixed to the positions of the openings 2b in the internal circumferential surfaces of the cylindrical thin plates 2. It is equipped with approximately H-shaped connectors 10 of sectional shapes corresponding to approximately H-shaped space sections for connecting PC piles 1 by inserting opening sections formed in series of joint metal fixtures 5 and 5 across approximately H-shaped space sections 5a and 5a in a state to butt the end faces of two PC piles 1 and 1 agaist each other so that the exposed surfaces of the joint metal fixtures 5 and 5 are connected to each other.
