Vibration Control
© ƒ½„¯ƒÀƒÂƒ¿ – A Concept for Progress and Quality 1/1

Building technology is becoming
increasingly complex, and technical
progress has led to a parallel rise in
the ambitions of building owners.
After 35, 30 and 25 dB(A), starting
from DIN 4109 and up to VDI 4100
vibration control level III, 20 dB(A)
and for waste water pipework without
the associated fittings noise, we
are already seeing values 5 dB(A)
lower than the vibration upper limit
being specified. At the same time,
legal developments are increasingly
oriented towards the sensitivities of
the consumers.
Traditionally, the standards that
have always had to be redefined for
fault-free quality are the generally
acknowledged handcraft rules.
The almost never-ending stream of
standards and regulations means that
anyone working on a building site,
including planners and installation
engineers, is facing an ever-increasing
liability risk.
The current situation
The greatest vibration damage
occurs in building technology when
noise in the installed equipment is
transferred to the building structure,
i.e. to the large “powerful” resonating
body. An added complication is
the fact that those involved in the
construction cannot predict the size
of the vibrations. Attachments that
have to absorb forces and static
loads, such as pipe anchor points,
are particularly problematic, as
there is mutual physical contradiction
between the tasks to be solved,
namely strength and vibration control.
If the stipulation is that the lower
vibration level must not exceed 25 or
20 dB(A), or in extreme cases even
5 dB(A), utmost care must be taken
to ensure that only the very best
products and the very latest technology
are used. Vibration damage,
which usually cannot be localised
and can often only be eliminated by
a total renovation, is one of the most
expensive construction defects.
Work that has not been carried out
according to the regulations and the
recognised technical rules can have
a “time bomb” effect, even if a client
overlooks existing defects during
acceptance and does not make a
complaint. If the work was not carried
out according to the current
state of technology and the generally
recognised installation standards,
subsequent buyers or users can still
hold the planner and the installation
company liable for any damage, for
a period of up to 30 years.
The solution is vibration control!
By making sure that all potential
sources of vibration and vibrationconducting
pipes are consistently
decoupled from the structure, you
can avoid every conceivable vibration
coupling in your area of responsibility.
Even with large loads and/or high
vibration intensities, the MÜPRO
vibration control programme offers
you system components to help
you solve the diverse vibration and
attachment problems in building technology.
From the simplest attachment using
pipe anchoring points, to the attachment
of small and large assemblies,
you will find a solution for every individual
attachment and vibration control
problem by using MÜPRO system
components.
Remember: Vibration that you have
under your control cannot spread
elsewhere.
