PROBLEM TO BE SOLVED: To provide a structure of a cut-off joint promoting water-tightness by providing a double cut-off structure in the structure of the cut-off joint for tying contiguous structures 3. SOLUTION: The structure of the cut-off joint for tying contiguous structures 3 comprises a waterstop material 1 consisting of a bending section 11 formed of a flexible material, fixed sections 12a connecting to both ends of the bending section 11 and projecting sections 13 projected from the roots of the fixed sections 12a and fixed metal fittings 2a arranged to the upper surfaces of the fixed sections 12a and combining the waterstop material 1 with the structures 3, and it is so constituted that the waterstop material 1 is placed so as to make the bending section 11 come to the outside between the structures 3 and that the projecting sections 13 are placed so as to bind them to the surfaces of the structures 3. The structure of the cut-off joint is so formed that a form of a contact surface between the fixed sections 12a and the fixed metal fittings 2a is a form resistant to the movement of the fixed sections 12.
