PROBLEM TO BE SOLVED: To provide a clamp for core shell joints where a joint for changing to a high-force bolt does not take much time. SOLUTION: This clamp for joints consists of a pinching part 11 that opposes one rear surface of a joint part, an opposing pinching part 13 that opposes the other rear surface of the joint part, a connection part 12 for connecting the pinching part to the upper portion of the opposing pinching part, and a shaft part 14 that is extended from the lower end part of the opposing pinching part to the pinching part side at right angle, where a projection 15 is formed on the inner surface of the pinching part and the opposing pinching part.
