Description

Features:

  • 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.

Performance:

  • MBT Couplers are designed and manufactured in accordance with BS EN ISO 9001.
