Abstract
PURPOSE: To make joint rigidity higher than that by conventional methods by applying the specified torque to a pair of nuts plural times to plastically work the same by giving the foregoing specified torque to tighten the nuts at the time of connecting deformed bars with a coupler for joint and said nuts.
CONSTITUTION: In connecting the steel bars 1, 1' formed with external thread-form nodes 1a, 1a' on the as-hot-rolled-surfaces by means of a coupler 2 with the external thread 2a for joint for joint and a pair of nuts 3, 3', the torque that can introduce the axial force corresponding to 43W67% of the yield point of the steel bars 1, 1' is given to the nuts 3, 3' plural times to plastically deform the external threads 1a, 1a' so as to make close contact with the internal threads 2a and the internal threads 3a of the nut 3. After this, the foregoing specified torque is given to the nut 3 to tighten the same. Above 67% of the foregoing torque, the external threads 1a will be crushed. This method permits the use of the easy-to-handle, small-size and lightweight tightening device.
