Tapered Thread couplers are suitable for the majority of applications which require the joining of rebars. They are normally supplied fitted to the end of the threaded bar and require only the engagement and tightening of the adjoining bar on site using a calibrated torque wrench.
Ancon Tapered Thread couplers are designed to meet the requirements of BS 8110 and are covered by the following approvals:
UK CARES Technical Report No. TA1-B (Sizes 12 – 50)
DIBt Approval No. Z-1.5-179. (Sizes 12 - 40)
KOMO Certificate No. K23495/03 (Sizes 12 - 40)
AFCAB Certificate No. M07/006 Rev. 2 (Sizes 12, 14, 16, 20, 25, 32 and 40)
Note: Not all coupler types and sizes are relevant to the national approvals shown. For details of coupler types and sizes relevant to each national approval please refer to the relevant approval document, which is available on request.
TTS Standard Couplers
Ancon Standard Tapered Thread Couplers are designed for use when connecting two bars of the same diameter, where one bar can be rotated. They are available to suit bar sizes 12mm to 50mm.
TTP Positional Couplers
Positional Tapered Thread Couplers are used to join two straight, bent or curved bars when neither bar can be rotated. Available to suit bar sizes 12mm to 50mm, they can also be used as a gap closer between two fixed bars. The male and female components provide a degree of adjustability and the connection is secured by the tightening of a locknut.
TTT Transition Couplers
The transition range is used to join rebars of different diameters when it is possible to rotate one bar, and is designed to achieve failure loads greater than 115% of the characteristic strength of the smaller diameter grade 500 bar. The couplers are designed to suit bar sizes 12mm to 50mm.
TTW Weldable Couplers
Tapered Thread Weldable couplers are used to connect reinforcing bars to structural steel sections or plates and are available to suit bar sizes 12mm to 50mm.
TTH Headed Anchors
Headed anchors provide dead end embedment in concrete and can be used as an alternative to hooked bars. They are available to suit bar sizes 12mm to 40mm.
