PROBLEM TO BE SOLVED: To provide a connecting method for concrete structures capable of assembling jacks accurately and easily and stretching tendons efficiently and safely. SOLUTION: Fastening members 5, 6 are fitted to tendons 3, 4 guided from a pair of concrete structures 1, 2 to connect both tendons 3, 4, and jacks 34a, 34b are assembled between the end faces of the concrete structures 1, 2 and the receiving members 18, 19 fitted to the tendons 3, 4 to apply tension to the stretches 3, 4. Both fastening members 5, 6 are further fastened, the jacks 34a, 34b are removed after this fastening, and uniform tension is applied to both tendons 3, 4 to connect a pair of concrete structures 1, 2. When the jacks 34a, 34b are assembled, holding pins 30 are inserted into the center holes of the jacks 34a, 34b from the receiving members 18, 19, and the jacks 34a, 34b are driven to apply tension to the tendons 3, 4.
