BT Headed Anchors
BT Headed Anchors
BT Headed Anchors create an anchorage in the concrete, replacing the need for cogged or hooked bar ends. They can simplify scheduling and bar placement, and reduce congestion in the concrete.
Designed for use on 12mm to 50mm reinforcing bars. BT Headed Anchors are internally threaded with metric threads to suit the BT coupler system. They create a full strength joint, the mode of failure being bar break.
BT Headed Anchors can be used in accordance with clause 13.1.4 of AS 3600:2018 to reduce the development length of reinforcing bar. For typical applications, the development length is reduced to 10 times the diameter of the bar*. Refined calculations can be performed using the bearing area (Ahead) values provided in the table below.
| Bar Diameter | 12 | 16 | 20 | 24 |
|---|---|---|---|---|
| Anchor Length (l) | 14 | 20 | 24 | 30 |
| External Dia. (d) | 38 | 50 | 64 | 76 |
| Net Bearing Area (mm2) | 980 | 1649 | 2765 | 3830 |
| Thread Size | M14 x 2.0 | M20 x 2.5 | M24 x 3.0 | M30 x 3.5 |
| Part No. | AA12 | AA16 | AA20 | AA24 |
| Bar Diameter | 28 | 32 | 36 | 40 |
|---|---|---|---|---|
| Anchor Length (l) | 33 | 36 | 42 | 45 |
| External Dia. (d) | 89 | 102 | 114 | 127 |
| Net Bearing Area (mm2) | 5366 | 7153 | 8822 | 11077 |
| Thread Size | M33 x 3.5 | M36 x 4.0 | M42 x 4.5 | M45 x 4.5 |
| Part No. | AA28 | AA32 | AA36 | AA40 |
Note: BTAA50 couplers can be manufactured. Contact Ancon for details.
