Application

Used to connect reinforcing bars of differing diameters.

Description

Transition couplers used to connect reinforcing bars of differing diameters, developing the full tensile strength of the smaller diameter bar together with the enhanced fatigue resistance.


Features and benefits:

  • For transition connections, only the smaller diameter bar end is enlarged and thread-rolled.
  • The larger diameter bar is skimmed and thread-rolled with the same thread form as applied to the smaller diameter bar, excluding the 32–40 mm connection.
  • The threads are such that the cross-sectional area of the bar ends are not reduced beyond that of the smaller diameter bar, thus ensuring the strength of the connection matches or exceeds that of the smaller bar.
  • Bartec Plus Type A utilizes an internally threaded coupler to join two cold-forged and thread-rolled bar ends together. Each bar end is threaded to half the length of the coupler. Used where the continuation bar can be rotated.
  • Bartec Plus Type B utilizes the same coupler as for the Type A, except one bar end is threaded for the full coupler length. Used where the continuation bar can be rotated for no more than one revolution.
  • Bartec Plus Type C utilizes the same coupler as for the Type A, together with locknuts and longer threads to the bar ends. Used where the continuation bar cannot be rotated.
