ITPL – Position Coupler with Tolerance
1 – Upset the end of each reinforcing bars to form an enlarged region using INCON’s forging machine.
2 – Thread the forged ends of the bars using INCON’s threading machine. The longer thread consists of an effective portion that extends over the enlarged zone and an ineffective portion that allows the coupler to be inserted temporarily.
3 – Screw the ITPL Coupler and lock nut completely into the bar of longer thread length.
4 – Align the second bar with the coupler while maintaining the allowable gap between them.
5 – Rotate the ITPL Coupler and the lock nut in the opposite direction until the threads on the second bar are completely engaged.
ITPL Coupler is composed of an internally threaded long coupler sleeve and a lock nut that are used to connect two threaded steel bars of the same size but with different threaded length.
ITPL Coupler is suitable for connecting two steel cages when a sufficient tolerance between the bars is required while rotation of the bars at both sides is restricted.
