Ancon Coupling & Tension Bar Systems
ANCON Coupler Systems
Fletcher Reinforcing offers the BT Threaded bar coupling system and the MBT Mechanical coupling system.
BT Threaded Bar Couplers
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.
The Type C coupler has an additional locknut 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 couplers comply in all respects to NZS 3101 when used with reinforcing bars to AS/NZS 4671. BT couplers size range: 12-40mm
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.
Ancon Anchors size range: 12-40mm
MBT Headed Anchor
MBT Headed Anchors are stocked in limited quantities, otherwise are made to order.
MBT couplers size range: 12-40mm
Nut Runner for MBT Couplers
The wrench is supplied with specially hardened heavy duty sockets.
**Subject to machine availability
- Design freedom
- Enhanced performance
- Independently tested
- Variable bar length
- Variable anchor spacing
- Less congestion
- Safer, faster installation
- No bar straightening
The use of Ancon KSN Anchors with BT threaded reinforcing bars can simplify concrete design at construction joints, typically in wall-to-slab applications.
The anchor is cast into the face of the concrete wall. When the formwork and thread protection is removed, the reinforcing bar is screwed into the anchor. Once all other reinforcement is installed, the adjoining slab is cast to complete the installation.
This system eliminates the drilling of formwork or concrete and the dangers associated with projecting bars and on-site bar straightening. It replaces bent or hooked bar ends simplifying bar scheduling and can be used to minimise congestion in the wall. In addition to their use in direct tensile applications, KSN Anchors have been independently tested in moment connections where they provide enhanced performance. KSN Anchors may also be suitable for other applications where a cast-in threaded insert is required.
