PURPOSE: A coupling device of a mold for concrete is provided to be stably coupled and allow a user to rapidly perform coupling work and separating work by improving a coupling structure and a separating structure of a SEPA tie and a fixture. CONSTITUTION: A coupling device of a mold for concrete comprises a SEPA tie (1), a cone type fixing pipe, an interlocking device, a support shaft pipe, an operating source rod (9), and a bracket (8). An inner connection part of the SEPA tie is inserted into the interlocking device of the cone type fixing pipe and is fixed. The interlocking device is installed inside the cone type fixing pipe, and an interlocking unit is formed inside an interlocking unit operating pipe for coupling and separating of the SEPA tie and the inner connection part. The operating source rod is inserted into the support shaft pipe by forming a male screw on one end, and a wrench unit is formed on the other end. |
