Vibration Control © ƒ½„¯ƒÀƒÂƒ¿ – A Concept for Progress and Quality 1/1 08/07 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. The challenge The solution
