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.

摘要： PROBLEM TO BE SOLVED: To provide a reinforced coupler capable of smoothly conducting connection rapidly even when a pair of reinforcing bars to be connected are placed at double levels or on the same core. SOLUTION: The reinforced coupler has each nipple 2, in which one ends are installed integrally at the end sections of a pair of each reinforcing bar, a pair of connecting members 3, in which base end sections are coupled with the nipples 2 in a bendable manner through coupling means and which have clamping bolt sections with screw sections for screwing at front ends, and clamping nuts 5 integrally screwing a section between the clamping bolt sections of a pair of the connecting members 3. The screw sections of one connecting member in a pair of the connecting members 3 is constituted of a right-hand thread while the screw sections of the other connecting member 3 is configured of a left-hand thread, and the right-hand thread is formed at one end section of the clamping nuts 5 and the left-hand thread at the other end section, and the nipples 2 and each connecting section with the connecting members 3 are composed of the coupling means in the bendable manner.
