Reinforcing Bars
Description:
Plain couplers is used to connect reinforcing bars of
the same size.  Couplers 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, nor
bar rotation are required.
couplers can also be used to join imperial, plain round
or deformed reinforcingbars. The bar ends are
supported within the coupler by two serrated saddles,
and as the lockshear 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 lockshear bolts of couplers up
to and including the 20mm 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.
