Description

Die Erfindung betrifft ein Schallschluckelement, insbesondere in Tafelform, bestehend aus zwei paralle- Ich. im Abstand voneinander angeordneten Wandungsflüchen, von denen eine perforiert ausgebildet ist und /mischen denen eine Füllung aus schallschluckendem Material angeordnet ist. sowie einem die Wandungsflädien verbindenden Rahmen.The invention relates to a sound-absorbing element, in particular in the form of a panel, consisting of two parallel I. wall surfaces arranged at a distance from one another, one of which is perforated and / or mixed with a filling made of sound-absorbing material. as well as a frame connecting the wall panels.

Derartige .Schallschluckelemente werden verwendet, um den Nachhall von Räumen zu reduzieren bzw. den Geräuschpegel in lärnierfüllten Räumen abzusenken, und sie werden weiterhin verwendet, um Wohn- und Siedlungsgebiete gegen Gerauschquellen, wie FlugpLitze. verkehrsreiche Straßen od. dgl. abzuschirmen.Such sound-absorbing elements are used to reduce the reverberation of rooms or lower the noise level in noise-filled rooms, and they continue to be used to protect residential and residential areas from sources of noise such as air traffic lightning. shield busy streets or the like.

Aus der C)KPS 2 33 223 sind schallabsorbierer.de V'erkleidungselemente für Raumw andungcn bekannt, die aus einem Hohlkörper aus unporösem Schaumkunststoff bestehen, dessen dem Raum zugekehrte Abdeckung mit Schall/.iitritisöffnungen ausgestattet ist, und der eine Füllung aufweist. Gegenüber entsprechenden, als I lelmholtz'sche Resonatoren wirksamen Hohlkörpern ergibt sieh durch eine vollkommene Ausfüllung des Innenraumes mit Schaumkunststoffteilclien eine im (<o Bereich der tieleii Frequenzen verbesserte Absorption, die durch Verwendung einer mittels Nadelstichen perforierten Folie weiter gesteigert wird. Damit ergibt sich ein leichtes, für trockene Innenräume geeignetes Verkleidungselement, das wohl den Nachteil zu mindern vermag, dessen Absorptionsfaklor aber zu wünschen übrig läßt und das schon seiner hohen Flüssigkeitsaufnahme wegen im Freien nicht anwendbar isi.Schallabsorbierer.de V'erkleidungselemente für Raumw andungcn are known from C) KPS 2 33 223, which consist of a hollow body made of non-porous foam plastic, the cover of which facing the room is equipped with sound / itritis openings and which has a filling. Compared with the corresponding, as I lelmholtz'sche resonators effective hollow bodies check results by a perfect filling of the interior with Schaumkunststoffteilclien improved in (<o field of tieleii frequencies absorption is further enhanced by using a perforated by needle sticks film. This results in a slight , cladding element suitable for dry interiors, which is able to alleviate the disadvantage, but whose absorption factor leaves something to be desired and which, due to its high liquid absorption, cannot be used outdoors.

Zum Auskleiden von Innenwänden von Gebäuden empfiehlt die US-PS 19 52 766 eine flexible Wandabdekkung, die aus miteinander verbundenen, unregelmäßig geformten Teilchen eines elastischen, schwammigen Materials, z. B. Schwammgummi, gebildet ist. Diese Teilchen sind miteinander verklebt oder vulkanisiert, und sie können zwischen Gewebebahnen verklebt oder so vulkanisiert werden, daß aus Gummi glatte äußere Oberflächen gebildet werden. Augenscheinlich können bei der Schwammgummiherstellung und -verarbeitung anfallende Reste verarbeitet werden, die allerdings nur in begrenztem Umfang verfügbar sind. Es ist aber auch möglich, weniger poröse Gummiteilchen zum Aufbau der flexiblen Abdeckung zu benutzen. Die offenbarte Abdeckung ist so flexibel, daß sie keinesfalls selbst tragend oder freistehend anwendbar ist. und sie dürfte auch kaum mattenartig aufhängbar sein. Es ist vielmehr erforderlich, sie auf akustisch zu isolierende bzw. zu entdröhnende Flächen aufzukleben. Auch hier sind sowohl Anwendung als auch Wirkung begrenzt. Infolge der hohen Flexibilität und Elastizität nimmt mit wachsender, die Absorptionswirkung steigernder Dicke der Schicht auch die Gefahr von unerwürschten. durch mechanische Beanspruchungen bewirkten Verformungen zu. so daß ein verbreiteter Einsatz nur bei dünnen Schienen erfolgen kann, und dickere, einen besseren \bsorptionsfaktor aufweisende .Schichten in ihrer Anwendung stark eingeschränkt sind. For lining the inner walls of buildings, the US-PS 19 52 766 recommends a flexible wall covering, which consists of interconnected, irregularly shaped particles of an elastic, spongy material, for. B. sponge rubber is formed. These particles are glued or vulcanized to one another and they can be glued between sheets of fabric or vulcanized so that smooth outer surfaces are formed from rubber. It appears that residues from the manufacture and processing of sponge rubber can be processed, although these are only available to a limited extent. But it is also possible to use less porous rubber particles to build up the flexible cover. The cover disclosed is so flexible that it can not be used in any way self- supporting or free-standing. and it should hardly be able to be hung up like a mat . Rather , it is necessary to glue them to surfaces to be acoustically isolated or deadened. Here, too, both application and effect are limited. As a result of the high flexibility and elasticity, the greater the thickness of the layer, which increases the absorption effect, the risk of undesirable effects. deformations caused by mechanical loads. so that widespread use can only take place with thin splints, and thicker layers with a better absorption factor are severely restricted in their use.

Der Erfindung liegt die Aufgabe zugrunde, ein Schallschluckelement der eingangs angegebenen Gattung zu schaffen, das bei hoher Schallabsorption mit •geringem Aufwand herstellbar ist und sowohl wegen seiner hohen mechanischen Beanspruchbarkeit als auch wegen seiner Wit'crungsbeständigkeit universell einsetzbar ist.The invention is based on the object of providing a sound-absorbing element of the type specified at the beginning to create that with high sound absorption • can be produced with little effort and both because of its high mechanical strength as well universally applicable because of its resistance to weathering is.

Diese Aufgabe wird dadurch gelöst, daß als scha'lschluckendes Material zerkleinertes Gummi von Mtgummireifen vorgesehen ist. Die Verwendung zerkleinerten Gummis von Altgummireifen, das geschnitzelt bzw. granuliert oder in Form von Schleif- und Fräsabfällcn vorliegt, ergibt einen mit geringem Aufwand zu beschaffenden, auch unter Witterungseinfluß beständigen, akustisch günstigen Füllstoff. Als überaus günstig zeigt sich, daß nicht nur bei der Aufarbeitung von Karkassen anfallende Abfälle, sondern auch Schnitzel von Altkarkassen verarbeitet werden,deren übliche anderweitige Beseitigung problematisch ist und hohe Kosten erfordert. Als besonders vorteilhaft erweist sich, daß von den Altreifen nicht nur die ausschließlich aus Gummi bestehenden Laufflächenteile, sondern auch die Karkasse selbst verwendbar ist. Die Zerkleinerungsarbeit läßt sich mit geringem Aufwände durchführen. Als vorteilhaft erweist es sich hierbei, daß die Eigenschaften des Gummis sieh unter Einwirkung von Feuchtigkeit bzw. Wasser und der im Freien auftretenden Temperaturen auch über lange Zeit nicht ändern, so daß das erfindungsgcniciß ausgebildete Schallschluckelement sich auch für Feuchträume und die \ufstellung im Freien eignet.This object is achieved in that as scha'lschuckendes material shredded rubber from Mtgummireifen is provided. The usage shredded rubber from old rubber tires, which is chipped or granulated or in the form of grinding and Milling waste is present, results in one that can be procured with little effort, even under the influence of the weather resistant, acoustically favorable filler. It turns out to be extremely cheap that not only with the Reconditioning of carcass waste, but also chips from old carcasses processed the usual other ways of eliminating them become problematic is and requires a high cost. It proves to be particularly advantageous that not only of the old tires the tread parts made exclusively of rubber, but also the carcass itself can be used. The crushing work can be carried out with little effort. It turns out to be advantageous here that the properties of the rubber see below Long-term exposure to moisture or water and the temperatures occurring outdoors do not change, so that the inventive concept formed Sound-absorbing element is also suitable for damp rooms and installation outdoors.

Einer vorteilhaften Ausgestaltung der Erfindung zufolge ist vorgesehen daß das zerkleinerte Gummi mit einer steppdeckenartigen Ummantelung versehen oder gemäß einer Weiterbildung zu einer zusammenhängenden Matte durch Kleben od. dgl. miteinander verbunden ist.According to an advantageous embodiment of the invention it is provided that the crushed rubber with provided with a quilt-like sheathing or, according to a development, to a cohesive one Mat by gluing od. The like. Connected to one another.

Um einen hohen Absorptionsfaktor auch bei lose eingegebenem zerkleinertem Gummi zu erzielen, wird einer vorteilhaften Ausgestaltung der Erfindung zufolge die Füllung so verdichtet, daß das zerkleinerte Gummi zwischen den Wandungsflächen dicht gepackt aufeinanderliegt.Proposal proposed that the perforated wall surface is caught behind with a grid. To one Achieving a high absorption factor even with loosely added comminuted rubber becomes an advantageous one Embodiment of the invention, the filling is compressed so that the crushed rubber between the Wall surfaces are tightly packed one on top of the other.
