The Varioguard
system
Standard units
Varioguard
is a galvanised steel safety barrier,
with a unit length of 4000mm, a height
of 900mm, and a base width of 700mm.
Since the lower section is considered
as part of the road, the effective base
width is 400mm. A box beam on top of
the unit is connected by SIGMA type
posts to the unit base. These posts
are bi directional, and because the
system is bolted together, they are
field replaceable. The standard element
has a weight of only 400kg, and incorporates
an integrated drainage section of 120mm
x 70mm.
Varioguard terminal
anchorage
Varioguard
is only anchored at the terminal ends.
The anchorage ensures the effectiveness
of the Varioguard system, and is made
after the system is in position. It
is completed by inserting a tube into
a core-drilled hole and fixing the Varioguard
terminal with an anchor post. Other
anchorage systems are available for
different applications.
Total system
For
speed of installation, the standard
4000mm Varioguard section is delivered
to site pre-assembled in 12000mm lengths.
The pre-assembled lengths are then bolted
together with the complete run standing
unfixed on the road. Anchorage is only
necessary at the end terminals and is
achieved by inserting a tube into a
core-drilled hole and fixing the Varioguard
terminal with an anchorage post. Varioguard
can also provide an effective transition
to other barrier systems or parapets,
and expansion joints can be installed
wherever needed i.e. on bridges and
viaducts.
