BOIEZELLEJ - AIRBORNE SOUND STEAM ER
Die B rf inching betrifft eine Sehalld&inpf erkonstruktion zur Verhinderung der Ausbreitung und Fortpflanzung von Schällquellen und Geräusche jeglicher Art, speziell in luftfilhrende Kanäle.The B rf inching concerns a safety damper construction for prevention the spread and reproduction of sound sources and Noises of any kind, especially in air ducts.
Luftkan&le, insbesondere für Luft- und Luf tklimatechnischen-Anlagen
haben neben ihren eigentlichen Aufgaben die unangenelime
Eigenschaft z.B. Maschinengeräusche, Sprechlaute und sonstige Schallquellen, ausgezeichnet weiterzuleiten..Ries ist in
den meisten Fällen nicht nur unerwünscht, sondern z.T. untragbar. Die Erfindung dient nun dem Zweck, durch Einbau des Schalldauipiers
zwischen Schallquelle und den zu schützenden Ort, die
Geräusch- oder Schallstarung wirksam zu verhindern.Air ducts, especially for ventilation and air-conditioning systems, have, in addition to their actual tasks, the unpleasant property of transmitting machine noises, speech sounds and other sources of sound. Ries is in
in most cases not only undesirable, but partly unacceptable. The invention now serves the purpose of effectively preventing noise or sound disturbance by installing the sound absorber between the sound source and the place to be protected.
Üs ist belcannt, dass mittels schallschluckendem Material ^z .B.
Mineralwolle) und geeigneter Anwendung, bei geringstem Aufwand, bestmögliche .Resultate erzielt werden. Neben individuelle Mas abnahmen sind vorailem industreli vorgefertigte Einbaukulissen
und Kuiissen-FertigschalldäEipier zu nennen. Die martgängige
Schalldämpfer sind meistens mit dem Nachteil behaftet, dass
sie sozusagen "laassgeschneidert" werden müssen und die Auswaul
und Bestimmung mitunter erhebliche Schwierigkeiten bereitet.Üs is belcannt that by means of sound-absorbing material ^ z .B.
Mineral wool) and suitable application, the best possible results can be achieved with the least amount of effort. In addition to individual measurements, vorailem industreli are prefabricated built-in scenery
and Kuiissen-FertigschalldäEipier. The martial one
Mufflers usually have the disadvantage that
they have to be "tailor-made", so to speak, and the selection and determination sometimes causes considerable difficulties.
Der Erfindung liegt die Aufgabe zugrunde, die bekannten Wachteile der gängigen Konstruktionen zu vermeiden, sowohl was die Vorfertigung, Arie auch die Auswahl und Bestimmung betrifft.The invention is based on the object of the known guard parts avoid the common constructions, both what the Prefabrication, Aria also concerns the selection and determination.
Diese Aufgabe wira erfindungsgemäss dadurch gelest, dass die
Einzelzeile des EOHKZiilLLEN-Ll/FTSCHALLDAMPFEii.-s aus irünjerwiederkehrenden,
gleichen Einzelteilen besteht und konstante Werte in.
den ausseren Massen, den freien Querschnitt und in dem Schallütrepfwert
aufweist»According to the invention, this object is achieved in that the
Individual line of the EOHKZiilLLEN-Ll / FTSCHALLDAMPFEii.-s consists of repeatedly recurring, identical individual parts and has constant values in the outer masses, the free cross-section and in the noise reduction value »

Die Einzelzelle des HOHRZELLBN-LUPTSCMLLDAJiPFER-S besteht im Wesentlichen aus vier Einzelteilen; das luftführende Kohr, aus perforierten Blech, die Dämmscheiben, vorzugsweise aus Hineralwollmatten, die Zwischenscheiben aus Blech und die Endstücke, strämungsgünstig ausgebildet, aus trichterf©rinig gepresstem Blech.The single cell of the HOHRZELLBN-LUPTSCMLLDAJiPFER-S consists of the Essentially made up of four parts; the air-carrying Kohr perforated sheet metal, the insulating disks, preferably made of wool mats, the intermediate plates made of sheet metal and the end pieces, designed to be streamlined, made of pressed funnel-shaped Sheet.
Die Einzelzellen werden durch nebeneinander- und ubereinanderreihen, in der erforderlichen Grosse paketiert durch zusammenhielten der Endstücke. Die liohrzellenpakete können dann in Kanäle eingeschoben werden, oder durch einfassen in einen tragenden Blechmantei z.B., zu einen Fertig-Luftschalldaaipfer ergänzt werden.The single cells are arranged side by side and on top of each other, Packaged in the required size by being held together of the end pieces. The cell packets can then be put into channels can be inserted, or by being surrounded by a load-bearing sheet metal casing, e.g. will.
Mit der Erfindung erzielten Vorteile sind voraliein dadurch gegeben, dass die Einzelteile des Grundeleiaents "Kohrzelle" aus gleichen öerienteileibestehen und somit die Fertigungstechnik Hiaximiert. Durch einfaches paketieren von einer entsprechenden Anzahl von itohrzellen kennen, je nach Bedarf, beliebig grosse Schalldampfereinheiten zusammengestellt werden. Durch die Standardwerte des lichten Querschnitts und der Schalldämpfung, wird die Auslegung unu Bestimmung starii vereinfacht.Advantages achieved with the invention are primarily given by that the individual parts of the basic element "Kohrzelle" The same series of parts and thus the manufacturing technology Hiaximized. By simply packing a corresponding Know the number of itohr cells, silencer units of any size can be put together as required. Through the default values the clear cross-section and the sound attenuation, is the interpretation unu determination starii simplified.
Ein Ausfanrungsbeispiel der Erfindung ist in der aeicunung dargestellt unu wird wie folgt beschrieben: Auf das luitführende iioiir aus vorzugsweise perforiertem ülech (A) werden, press aneinandergereiht, abwechselnd Dänuascheibe (C) unu Zwischenscheibe (D) aufgezogen und die beiden Enden mit aen Endstücken (B) abgeschlossen. Die so entstandene ttotir— zeile (siehe Längsschnitt u. Querschnitt) kann zu beliebig grossen Schalidiiupfereinheiten (sielie Beispiel Z) paketiert, werden.An exemplary embodiment of the invention is shown in the aeicunu is described as follows: On the luit-leading iioiir made of preferably perforated surface (A) are pressed together, alternately pulled on Danish washer (C) and intermediate washer (D) and the two ends with aen end pieces ( B) completed. The resulting ttotir- line (see longitudinal section and cross section) can be packaged into any size blanket units (see example Z).
