難い場合には次の調整操作を行う。 As shown in FIG. 1, one end of the threaded rod 5 is screwed into the sleeve 3 of one reinforcing bar 1 in advance, nuts 6 and 7 are attached to this threaded rod, and the connecting adjustment body 9 is attached to the screw hole 9a. Connect via. A predetermined distance is left between the bottom of the screw hole 9a and the end of the screw rod 5. First, reinforcing bars 1 and 2 are arranged at regular intervals. The distal end surface of the adjusting threaded rod portion 9b of the connection adjusting body 9 is close to the end surface of the sleeve 4. Next, when the nut 6 is turned, the threaded rod 5 and the connection adjustment body 9 are rotated and moved toward the sleeve 4 through the nut 7, which is in close contact with each other, and the adjustment threaded rod portion 9b is eventually screwed into the threaded hole 4a of the sleeve. . At this time, if it is difficult to insert the adjusting threaded rod part 9b due to a deviation in the screw pitch between the adjusting threaded rod part 9b and the sleeve 4, the next adjustment operation is performed.

Stop screwing in the threaded rod when it has been screwed in to a predetermined length. The nut 8 is advanced and brought into strong contact with the end face of the sleeve 4, and the nuts 6 and 7 are also brought into strong contact with the end faces of the sleeve 3 and the connection adjustment body 9, respectively, to complete the joint work. By tightening the nuts 6, 7, and 8, the connection between the threaded rod 5, the sleeve 3, and the connection adjustment body 9, and the connection between the threaded rod portion 9b and the sleeve 4 are fixed and strengthened.

端面に密着させて、継手作業を終了する。 To explain the joint work in this example,
First, when the nuts 16 and 17 are turned from the state shown in the third figure, the threaded rod 15 is moved from the sleeve 13 to the sleeve 14.
Moving toward the side, the tip of the adjustment threaded rod portion 19b of the connection adjustment body 19 enters the opening of the threaded hole 14a of the sleeve. At this time, if the thread pitches of the adjusting threaded rod part 19b and the threaded hole 14a of the sleeve match, the connecting adjustment body 19 is connected to the adjusting threaded rod part 19b.
When the adjustment screw rod is turned in the direction of entering the screw hole 14a, the adjustment screw rod portion is screwed into the screw hole 14, and at the same time, the screw rod 15 is screwed into the screw hole 19a of the connection adjustment body.
If the screw pitch is incorrect, screw hole 14
If the adjusting threaded rod part 19b does not fit inside a,
Turn the nuts 16 and 17 to slightly move the threaded rod 15 toward the sleeve 13, and then adjust the adjustment threaded rod portion 19.
Slightly move back the tip of b to adjust the pitch, and then screw in the threaded rod. When the adjusting threaded rod part 19b has entered a predetermined length, the screwing of the adjusting threaded rod part is stopped, the nut 18 is brought into close contact with the end surface of the sleeve 14, and the joint work is completed.
