BT parallel threaded couplers are suited to projects which require high volumes of couplers. They produce a full strength joint and yet are one of the smallest couplers in the Ancon range. The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bar.
BT couplers comply in all respects to AS 3600 when used with reinforcing bars to AS 4671.
Full destructive tests have been carried out to show compliance with the following codes: ACI 349; ASME III DIV 2 (ACI 359); ACI 318;
CSA CAN 3 – N2872.
BT couplers of size range 12-40mm are approved for use on RMS (formerly RTA) contracts.
BT Type A
The Type A coupler is used for applications where the continuation bar can be rotated. The ends of the bars are upset and threaded for half the length of the coupler.
BT Type B
The Type B coupler uses the same coupler as the Type A system, but one bar is threaded for the full coupler length. It is designed for applications where it is difficult but not impossible to rotate the continuation bar.
BT Type C
The Type C coupler has additional locknuts and is used where the continuation bar cannot be rotated. The continuation bar is threaded for the full length of the coupler plus the length of the locknut.
BT Transition couplers are available to join bars of different diameters, for details on the BT Transition Couplers please click here.

Ancon are pleased to confirm that we are now Associate Members of Think Brick Australia in support of their aim to inspire contemporary brick architecture and building design in all areas of the built environment including commercial, residential and landscape.
Ancon will be exhibiting at the 29th Biennial Concrete 2019 Conference, between 8-11 September in Sydney, where we will showcase a range of high integrity steel fixings engineered specifically for structural concrete construction.
