The MBT Continuity Coupler allows reinforcement to be extended at construction joints without the need to drill.
The MBT Continuity Coupler allows reinforcement to be extended at construction joints without the need to drill or otherwise substantially deface the formwork at construction joint locations
The female part of the coupler is fixed to the formwork with the aid of a nail plate
After removal of the formwork, the nail plate protects the internally threaded end of the coupler
It is advisable to loosen the nail plate to break the bond with the concrete whilst it is still 'green'
When the nail plate is removed, the male section can be screwed into the existing section of the coupler
12 and 16 mm couplers have additional locknuts which are used to secure the connection
The two sections of sizes 20 to 40 mm couplers are locked together by an expanding cone in the male section
They are easy to install and achieve failure loads higher than 115% of the characteristic yield strength of grade 500 reinforcing bar
Neither bar end preparation to form threads or bar rotation are required
The bar ends are supported within the coupler by two serrated saddles, and as the lock-shear bolts are tightened, the conical ends embed themselves into the bar. As this happens the serrated saddles bite into both the bar and the shell of the coupler
The lock-shear bolts of couplers up to and including the ET20 can be tightened using a ratchet wrench. For larger couplers a nut runner is recommended
In all cases heavy duty sockets should be used
When the pre-determined tightening torque for the bolts is reached, the heads shear off leaving the top of the installed bolt slightly proud of the coupler. This provides an instant visual check of correct installation
MBT Couplers can also be used to join imperial, plain round or deformed reinforcing bars
MBT Continuity Couplers can be supplied with a longer central stud to act as a gap closer
