Transflex Bridge Joints - Universal Sealants

USL
BridgeCare
Description
The USL Transflex bridge joint
system comprises of 8 No.
standard models designed to
accommodate movement up to
330mm by shear deformation of
the elastomer between the steel
components.
Each model incorporates steel
angles designed to be bolted to
the structural deck and a steel
bridging plate system which spans
the open joint gap.
The elastomer case is highly
resistant to oils, solvent spillage
and the trafficked surface
includes an anti-skid pattern for
safety having a rubber to rubber
coefficient of static friction of 0.69.
Each model is specifically designed
to accommodate horizontal and
skew movement and will also
accommodate vertical movement
due to rotation of up to 6mm.

Special steel clipped washers are
provided with each unit designed
specifically for the Transflex joint.
Stainless steel washers to the
same high specification can be
supplied to special order.
It is important that the correct
washer is used in each case.
When additional waterproofing
is specified a continuous length
of Uniflex membrane should be
bonded to the levelling bed with
adhesive over the full width of the
Transflex joint unit. Drain outlets
will be incorporated.
Rebond profiles
During installation it is sometimes
necessary, for practical reasons, to
cut a Transflex unit on-site. In order
to maintain the integrity of the joint
between each module, male and
female rebond profiles are available
for each unit to reinstate the end
configuration as required.
