Description
In der Bautechnik ist bekannt, dass zur möglichst guten Luftschalldämmung Bauteile mit möglichst großer masse ausgebildet sein sollten, also Wände beispielsweise aus massivem Kalksandstein oder Beton, wobei die Kehrseite dieser Ausbildung in einer umso besseren Körperschall-Leitfähigkeit besteht. Zum Schallschutz in Bezug auf Körperschall- Ausbreitung, beispielsweise zur Trittschalldämmung, sind dagegen weiche Baustoffe not wendig.It is known in construction technology that components are used for the best possible airborne sound insulation the largest possible mass should be formed, i.e. walls made of solid, for example Lime sandstone or concrete, the downside of this training in an all the better Structure-borne noise conductivity exists. For sound insulation in relation to structure-borne noise Spreading, for example for impact sound insulation, on the other hand, requires soft building materials manoeuvrable.
Aus dem Stand der Technik sind verschiedene Dämmelemente bekannt. Die DE-OS 15 72 497 beschreibt einen Schalldämmkörper zur Kapselung von Maschinen. Die Kapselung ist doppelwandig mit dazwischen angeordnetem Vakuum. Ein derartiger Schalldämmkörper eignet sich aber offenbar nicht für eine Trittschalldämmung, denn dazu müsste das Ele ment nicht nur schalldämmend, sondern auch trittfest sein. Hier stehen sich aber widerstreitende Forderungen gegenüber.Various insulation elements are known from the prior art. DE-OS 15 72 497 describes a soundproof body for encapsulating machines. The encapsulation is double-walled with vacuum in between. Such a soundproof body but is obviously not suitable for impact sound insulation, because the Ele not only soundproofing, but also hard-wearing. But here are conflicting claims.
Aus der US 2 837 779 ist ein Dämmelement in Gestalt eines flachen Kastens bekannt, der eine Vakuumkammer bildet und dessen beide Hauptwände durch ein dazwischen angeord netes Gitter im Abstand voneinander gehalten werden. Dieses bekannte Dämmelement eignet sich aber nur zur Wärmedämmung, nicht zur Schalldämmung und schon gar nicht zur Trittschalldämmung, weil der Kasten aufgrund der starren Verbindung seiner beiden Hauptwände durch das dazwischenliegende Gitter eine Art Resonanzkasten bildet. From US 2 837 779 an insulation element in the form of a flat box is known, the forms a vacuum chamber and the two main walls of which are arranged between them netes are kept at a distance from each other. This well-known insulation element but is only suitable for thermal insulation, not for sound insulation and certainly not for impact sound insulation, because the box due to the rigid connection of its two Main walls through the grille in between forms a kind of resonance box.
Aus der US 4 444 821 ist ein Vakuumdämmelement bekannt, das eine Folienhülle mit ei ner eingelegten Glasfasermatte aufweist und im Inneren evakuiert ist. Auch dieses Element ist als Wärmedämmelement vorgesehen. Es könnte auch als Schalldämmelement, jedoch nicht zur Trittschalldämmung verwendet werden.From US 4 444 821 a vacuum insulation element is known which has a film envelope with egg ner inserted glass fiber mat and is evacuated inside. This element too is intended as a thermal insulation element. It could also be used as a soundproofing element, however not to be used for impact sound insulation.
Aufgabe der Erfindung ist es, ein Luft- und Körperschall gleichermaßen dämmendes Schalldämmelement zu schaffen, das insbesondere auch für Trittschalldämmung geeignet ist.The object of the invention is an air and structure-borne noise equally insulating To create soundproofing element that is particularly suitable for impact sound insulation is.
Diese Aufgabe wird erfindungsgemäß durch ein Schalldämmelement, vorzugsweise in Form einer Schalldämmplatte und nach Bedarf in Form eines sonstigen Schalldämmkör pers, dadurch gelöst, dass das Schalldämmelement als evakuierter, jedoch ein schlecht schalleitendes Stützmaterial enthaltender Hohlkörper ausgebildet ist. Das Schalldämmele ment besteht also aus einer gasdichten Außenhaut, das einen Hohlraum umschließt, aus welchem die Luft im wesentlichen vollständig evakuiert ist und der lediglich ein den Schall schlecht leitendes Stützmaterial enthält, der das Volumen des Hohlraums zu einem möglichst geringen Anteil ausfüllt und ein zusammendrücken der Außenhaut unter der einwirkung des äußeren Luftdrucks verhindert. Als solches schlecht schalleitendes Stütz material kommen beispielsweise Kokosfasern als natürliches Material oder offenzelliger Schaumstoff in Betracht; geschlossenzellige, Lufteinschlüsse enthaltende und daher nicht evakuierbare Materialien wären dazu natürlich ungeeignet. Die Außenhaut des erfindungsgemäßen Schalldämmelements besteht aus einem eben falls möglichst schlecht schalleitenden Material, also bei spielsweise aus einer Kunststoffolie.This object is achieved by a sound insulation element, preferably in In the form of a soundproofing panel and, if necessary, in the form of another soundproofing body pers, solved in that the soundproofing element as evacuated, but a bad one hollow body containing sound-conducting support material is formed. The soundproofing element consists of a gas-tight outer skin that encloses a cavity which the air is essentially completely evacuated and which is only one Sound containing poorly conductive support material, which the volume of the cavity to one fills as small a portion as possible and squeezes the outer skin under the external air pressure prevented. As such poorly sound-conducting support For example, coconut fibers come as a natural material or open-celled Foam into consideration; closed-cell air pockets and therefore not Evacuable materials would of course be unsuitable for this. The outer skin of the Sound insulation elements according to the invention consists of a flat if possible poorly sound-conducting material, that is for example from a plastic film.
Das erfindungsgemäße Schalldämmelement unterbindet aufgrund seines evakuierten, also luftleeren Innenraums eine Luft schallübertragung sowie aufgrund der schlecht schalleitenden Eigenschaften seines inneren Stützmaterials und seiner Außen haut auch eine Körperschallübertragung. Die Verwendbarkeit eines solchen Schalldämmelements nach der Erfindung reicht also beispielsweise von der Verwendung als Trittschall-Dämm platte unter einem Estrich bis zur Verwendung als schall dämmende Leichtbau-Trennwand oder dgl. Der Einsatzbereich ist jedenfalls außerordentlich vielseitig.The sound insulation element according to the invention prevents due to of its evacuated, i.e. airless interior sound transmission as well as due to the poor sound transmission Properties of its inner support material and its exterior also strikes a structure-borne sound transmission. The usability of such a sound insulation element according to the invention is sufficient for example from the use as impact sound insulation plate under a screed until use as sound insulating lightweight partition or the like. The area of application is at least extraordinarily versatile.
Ein Ausführungsbeispiel der Erfindung ist in der anliegenden schematischen Zeichnung dargestellt und wird nachstehend kurz beschrieben.An embodiment of the invention is in the attached schematic drawing and is briefly below described.
Die Zeichnung zeigt ein Schalldämmelement nach der Erfindung in Form einer Schalldämmplatte, bestehend aus einer luftdich ten Außenhaut 1, die einen inneren Hohlraum 2 umschließt, und einem den inneren Hohlraum 2 teilweise ausfüllenden Stütz material 3.The drawing shows a soundproofing element according to the invention in the form of a soundproofing panel, consisting of an airtight outer skin 1 , which encloses an inner cavity 2 , and a supporting material 3 partially filling the inner cavity 2 .
Die Außenhaut 1 besteht aus einem luftdichten und den Schall möglichst schlecht leitenden Material, beispielsweise einer Kunststoffolie. Das innere Stützmaterial 3 besteht aus einem eine möglichst gute Steifigkeit besitzenden, dabei aber den Schall möglichst schlecht leitenden Material. In Betracht kommen beispielsweise Kokosfasern als natürliches Material oder offenzelliger steifer Kunststoffschaum. Der innere Hohl raum 2 ist evakuiert, also im wesentlichen vollständig luft leer.The outer skin 1 consists of an airtight material that conducts the sound as poorly as possible, for example a plastic film. The inner support material 3 consists of a material which has the best possible rigidity, but at the same time does not conduct the sound as badly as possible. For example, coconut fibers can be considered as a natural material or open-cell rigid plastic foam. The inner cavity 2 is evacuated, so essentially completely air-free.
Die Herstellung eines dem Element nach der Erfindung kann in der Weise erfolgen, daß eine entsprechend konfigurierte Stützmaterialanordnung von dem luftdichten Außenhautmaterial umhüllt wird oder in eine vorbereitete Außenhülle eingebracht wird, wonach die Luft aus dem inneren Hohlraum 2 durch eine verbleibende Absaugöffnung in der Außenhaut abgesaugt und diese Außenhaut dann sogleich verschlossen, z. B. verschweißt wird.The manufacture of the element according to the invention can take place in such a way that a correspondingly configured support material arrangement is enveloped by the airtight outer skin material or is introduced into a prepared outer shell, after which the air is sucked out of the inner cavity 2 through a remaining suction opening in the outer skin and this outer skin then immediately closed, z. B. is welded.
