AkustikplatteAcoustic panel

Beschreibung; Description ;

Die Erfindung betrifft eine Akustikplatte zur Bildung von schallabsorbierenden Raumdecken oder -wänden in Sandwich-Bauweise aus einer homogenen Trägerplatte aus geschäumtem Werkstoff und aus einer ein- oder beidseitigen, mit der Trägerplatte fest verbundenen Deckschicht.The invention relates to an acoustic panel for forming sound-absorbing room ceilings or walls in a sandwich construction from a homogeneous carrier panel made of foamed material and a cover layer on one or both sides firmly connected to the carrier panel.

Akustikplatten dieser Art sind seit langem bekannt und werden häufig zur Schallabsorption in Innenräumen und dergleichen verwendet. Der gewählte Werkstoff für die Trägerplatte ist dabei in Bezug auf den Schallabsorptionsgrad der Akustikplatte entscheidend. Es werden dazu elastische, thermoplastische und duroplastische Werkstoffe bereits in großem Umfang verwendet. Die Beschichtung dieser Trägerplatten ist dabei unerläßlich, sei es, um eine ausreichende Festigkeit der gesamten Akustikplatte, insbesondere gegen Durchbiegung zu erzielen, sei es, um eine befriedigende dekorative Gestaltung zu erreichen, oder auch nur, um der Akustikplatte eine gewisse Schmutzunempfindlichkeit geben zu können. Einen positiven Einfluß auf die Schallabsorption der Akustikplatte hat eine solche Beschichtung nicht, sondern sie bewirkt eher das Gegenteil und verschlechtert die Schallisolierung einer solchen Akustikplatte.Acoustic panels of this type have been known for a long time and are often used for sound absorption in interior rooms and the like. The material selected for the carrier panel is crucial in relation to the sound absorption level of the acoustic panel. Elastic, thermoplastic and thermosetting materials are already used on a large scale for this purpose. The coating of these carrier panels is essential, whether to achieve sufficient strength of the entire acoustic panel, especially against bending, to achieve a satisfactory decorative design, or even just to give the acoustic panel a certain degree of dirt resistance. Such a coating does not have a positive effect on the sound absorption of the acoustic panel, but rather has the opposite effect and worsens the sound insulation of such an acoustic panel.

Die Erfindung hat sich deshalb die Aufgabe gestellt, eine Akustikplatte der eingangs näher bezeichneten Art so auszuführen, daß unter Beibehaltung einer genügenden mechanischen Stabilität der Verbundkonstruktion die Schallabsorption wesentlich verbessert wird, ohne daß dazu aufwendige zusätzliche Maßnahmen erforderlich wären.The invention therefore has the task of designing an acoustic panel of the type described in more detail above in such a way that, while maintaining sufficient mechanical stability of the composite construction, the sound absorption is significantly improved without the need for complex additional measures.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Trägerplatte aus einem porösen, elastischen Harz besteht und für die Deckschicht ein in der Fläche biegsames, sonst aber steifes, poröses Vlies oder Gewebe verwendet wird. In einer bevorzugten Ausführung besteht die Trägerplatte aus Melaminharz. Überraschenderweise wurde dabei gefunden, daß die so hergestellte Akustikplatte einen im Mittel um 15% über demjenigen der reinen Trägerplatte liegenden Schallabsorptionsgrad aufweist. Dadurch ist eine derartige Akustikplatte den bisher bekannten Kombinationen von Verbundwerkstoffen zu dem vorgenannten Zweck überlegen. Trotzdem hat die erfindungsgemäße Ausführung nicht zu einer Verschlechterung der mechanischen Werte geführt, so daß solche Akustikplatten nach wie vor gut geeignet sind, beispielsweise ebene, untergehängte Raumdecken zusammenzustellen. According to the invention, the object is achieved in that the support plate consists of a porous, elastic resin and a surface-flexible, but otherwise stiff, porous fleece or fabric is used for the cover layer. In a preferred embodiment, the support plate consists of melamine resin. Surprisingly, it was found that the acoustic panel produced in this way has an average sound absorption level that is 15% higher than that of the pure support plate. This makes such an acoustic panel superior to the previously known combinations of composite materials for the aforementioned purpose. Nevertheless, the embodiment according to the invention has not led to a deterioration in the mechanical values, so that such acoustic panels are still well suited for assembling, for example, flat, suspended ceilings.

Besondere Anforderungen werden an die Deckschicht nicht gestellt. Sie kann aus Glas-, Kunst- oder Naturfasern bestehen, die mittels eines organischen oder anorganischen Klebstoffes miteinander verklebt sind, und zwar so, daß dadurch die Porosität der Deckschicht nicht gestört ist. Besondere technologische Schwierigkeiten bringt ein derartiges Verfahren nicht mit sich.There are no special requirements for the cover layer. It can consist of glass, synthetic or natural fibers that are bonded together using an organic or inorganic adhesive in such a way that the porosity of the cover layer is not impaired. This type of process does not entail any special technological difficulties.

Weitere Merkmale der Erfindung, insbesondere hinsichtlich der günstigen und vorzugsweisen Abmessungen der Akustikplatte enthalten die Unteransprüche.Further features of the invention, in particular with regard to the favorable and preferred dimensions of the acoustic panel, are contained in the subclaims.

Die Erfindung wird nachstehend anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert. Es zeigenThe invention is explained in more detail below with reference to an embodiment and the drawing.

Fig. 3 ein Diagramm für den Schallabsorptionsgrad der erfindungsgemäßen Akustikplatte.Fig. 3 is a diagram for the sound absorption coefficient of the acoustic panel according to the invention.

In Fig. 1 ist eine Akustikplatte gezeigt, die aus einer Trägerplatte 1 und je einer auf beiden Seiten der Trägerplatte 1 aufgeklebten Deckschicht 2 besteht. Während die Trägerplatte 1 aus geschäumten Melaminharz gebildet ist, werden für die Deckschichten 2 am besten Glasfaservliese verwendet, die auf der Trägerplatte 1 aufgeklebt sind und deren Fasern untereinander ebenfalls verklebt sind, und zwar so, daß die Porosität weder der Trägerplatte 1 noch der Deckschichten 2 gestört ist, so daß die Raumluft durch die gesamte Akustikplatte zirkulieren kann. In Fig. 2 ist an der Trägerplatte 1 nur eine einzige Deckschicht 2 angebracht, und zwar in der von der Raumdecke bzw. Raumwand wegweisenden Richtung.Fig. 1 shows an acoustic panel that consists of a carrier panel 1 and a cover layer 2 glued to both sides of the carrier panel 1. While the carrier panel 1 is made of foamed melamine resin, it is best to use glass fiber fleece for the cover layers 2, which are glued to the carrier panel 1 and whose fibers are also glued to one another, in such a way that the porosity of neither the carrier panel 1 nor the cover layers 2 is disturbed, so that the room air can circulate through the entire acoustic panel. In Fig. 2, only a single cover layer 2 is attached to the carrier panel 1, in the direction away from the ceiling or wall.

Im Schaubild der Fig. 3 ist der Schallabsorptionsgrad über der Schallfrequenz aufgetragen, ermittelt durch Hallraumprüfung entsprechend DIN 52212. Zum Vergleich ist außer der erfindungsgemäß zusammengesetzten Akustikplatte (Kurve I) der Verlauf bei einer reinen Trägerplatte 1 ohne Deckschichten 2 eingezeichnet (Kurve II).In the diagram in Fig. 3, the sound absorption coefficient is plotted against the sound frequency, determined by reverberation room testing according to DIN 52212. For comparison, in addition to the acoustic panel assembled according to the invention (curve I), the curve for a pure carrier panel 1 without cover layers 2 is shown (curve II).

Es versteht sich von selbst, daß aus Gründen des Brandschutzes die erfindungsgemäße Akustikplatte in schwer entflammbarer oder nicht brennbarer Ausrüstung entsprechend den gesetzlichen Vorschriften anzufertigen ist, wenn dies vorgeschrieben ist.It goes without saying that, for reasons of fire protection, the acoustic panel according to the invention must be manufactured in flame-retardant or non-flammable equipment in accordance with legal regulations if this is required.
