Wall
spacer made from rigid PVC Tube with
extra wide contact surface to
formwork with an inner diameter of
22m/m and chamfered end pieces. The
assembly consists of the Tube, two
end pieces with wide double rims and
a serrated labyrinth seal and three
plugs for installation after
dismantling of the formwork.
In 1909 the first supporting
parts were developed in central Europe to assure
the correct concrete cover over the
reinforcement bars and are now more or less
standardized and used worldwide. Within a
relatively short time it was understood that the
exact definition of the concrete cover depends
on the reinforcement and the surroundings, and
that the form and type of spacers used are of
significant importance in respect to the
durability of reinforced concrete structures.
