Description

Die Erfindung betrifft eine Deckenplatte mit einer nach dem Verlegen unteren raumseitigen Oberfläche und mit einer deckenseitigen Oberfläche für eine zugleich Tragprofile aufweisende Zwischendecke. Die Deckenplatte nach der Erfindung besteht aus mindestens zwei miteinander verklebten Plattenelementen aus einem schalldämmenden Werkstoff, wobei die raumseitige Oberfläche Vertiefungen und/oder Schallabsorptionsöffnungen aufweist und die deckenseitige Oberfläche glatt oder strukturiert ist.The invention relates to a ceiling plate with a lower side surface after laying and with a ceiling-side surface for a supporting profiles at the same time having false ceiling. The ceiling plate according to the invention consists of at least two bonded together plate elements made of a sound-absorbing material, wherein the room-side surface recesses and / or sound absorption openings and the ceiling-side surface is smooth or textured.

Eine derartige Deckenplatte ist aus der EP 0 664 365 B1 bekannt. Die dort beschriebene Platte besteht ebenfalls aus mindestens zwei miteinander verbundenen Plattenelementen die mit einer Schalldämmsperrschicht aus einem Klebstoff miteinander verbunden sind. Diese bekannte Platte ist dabei so aufgebaut, daß sie im eingebauten Zustand bei der oben liegenden deckenseitigen Oberfläche Vertiefungen und/oder Schallabsorptionsöffnungen aufweist, und daß die raumseitige Oberfläche glatt oder strukturiert ist.Such a ceiling panel is known from EP 0 664 365 B1. The plate described there also consists of at least two interconnected plate elements which are connected to each other with a sound barrier layer of an adhesive. This known plate is constructed so that it is in the installed state at the top lying recessed surface side recesses and / or sound absorption openings, and that the room-side surface is smooth or textured.

Es hat sich nun gezeigt, daß diese Platte in bezug auf die Schalldämm- und Schallabsorptionseigenschaften noch nicht befriedigende Eigenschaften aufweist.It has now been found that this plate does not yet have satisfactory properties in terms of sound absorption and sound absorption properties.

Ausgehend hiervon ist es deshalb die Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Deckenplatte derart weiterzubilden; daß die Schalldämm- und Schallabsorptionseigenschaften verbessert werden.Based on this, it is therefore the object of the present invention to develop a generic ceiling plate in such a way; that the sound absorption and sound absorption properties are improved.

Die Aufgabe der vorliegenden Erfindung wird durch eine Deckenplatte mit den Merkmalen des Schutzanspruches 1 gelöst. Die Unteransprüche zeigen vorteilhafte Weiterbildungen auf.The object of the present invention is achieved by a ceiling plate with the features of the protection claim 1. The dependent claims show advantageous developments.

Die Dekkenplatte ist so aufgebaut, daß die raumseitige Oberfläche im eingebauten Zustand Vertiefungen und/oder Schallabsorptionsöffnungen aufweist und die deckenseitige Oberfläche glatt oder strukturiert ist. Wesentlich ist nun, daß mindestens ein Plattenelement der Deckenplatte raumseitig, an der der Schalldämmsperrschicht zugewandten Seite ebenfalls Schallabsorptionsöffnungen und/oder Vertiefungen aufweist.The cover plate is constructed so that the room-side surface in the installed state has recesses and / or sound absorption openings and the ceiling-side surface is smooth or textured. It is essential that at least one plate element of the ceiling plate on the room side, on the side facing the sound barrier layer also has sound absorption openings and / or depressions.

Überraschenderweise hat es sich gezeigt, daß eine derartige Platte in bezug auf die Schallabsorption und Schalldämmung überlegene Eigenschaften aufweist. Besonders überraschend war hierbei, daß durch die Schalldämmsperrschicht die Vertiefungen und/oder Schallabsorptionsöffnungen in ihrer Funktion nicht beeinträchtigt werden.Surprisingly, it has been found that such a plate has superior properties in terms of sound absorption and sound insulation. It was particularly surprising here that the depressions and / or sound absorption openings are not impaired in their function by the sound damping barrier layer.

Eine bevorzugte Ausführungsform der Erfindung schlägt vor, daß gleichzeitig noch das deckenseitige Plattenelement an der Stirnseite in Richtung der Decke abgefast ist. Dadurch ist es möglich, daß die Deckenplatten in einem geringeren Abstand zum Tragprofil befestigt werden können. Dadurch können wiederum die Schallabsorptions- bzw. Schalldämmeigenschaften des Deckenplattenelements gezielt beeinflußt werden. Bevorzugt wird das deckenseitige Plattenelement in einem Winkel von 20-60° abgefast.A preferred embodiment of the invention proposes that at the same time still the ceiling-side plate element is chamfered at the front side in the direction of the ceiling. This makes it possible that the ceiling panels can be attached at a shorter distance from the support profile. As a result, in turn, the sound absorption or sound insulation properties of the ceiling panel element can be influenced in a targeted manner. Preferably, the ceiling-side plate member is chamfered at an angle of 20-60 °.

Bei der erfindungsgemäßen Deckenplatte ist die raumseitige Oberfläche mit Vertiefungen und/oder Schallabsorptionsöffnungen versehen. Die Ausbildung dieser Vertiefungen und Schallabsorptionsöffnungen ist an und für sich aus dem Stand der Technik bekannt. Meistens werden diese Vertiefungen durch eine Feinlochung hergestellt.In the case of the ceiling panel according to the invention, the room-side surface is provided with recesses and / or sound absorption openings. The formation of these recesses and sound absorption openings is in and of itself known from the prior art. Mostly, these depressions are made by a fine perforation.

Die deckenseitige Oberfläche der erfindungsgemäßen Deckenplatte ist glatt oder strukturiert. Eine Strukturierung kann z.B. in der Art realisiert werden, daß auf die deckenseitige Oberfläche noch ein zusätzliches Element, z.B. ein Vlies, aufgelegt oder an der deckenseitigen Oberfläche befestigt wird.The ceiling-side surface of the ceiling tile according to the invention is smooth or textured. Structuring may e.g. be realized in such a way that on the ceiling-side surface nor an additional element, e.g. a fleece, laid on or attached to the ceiling-side surface.

Bei der Deckenplatte nach der Erfindung sind mindestens zwei Plattenelemente vorgesehen. Bevorzugt ist es hierbei, die Deckenplatte aus zwei Plattenelementen zu bilden, d.h. aus einem raumseitigen Plattenelement und aus einem deckenseitigen Plattenelement. Die Dicke der einzelnen Platten kann dabei entweder gleich sein oder auch variieren. Die Dicke der Einzelplatten liegt bevorzugt im Bereich von 5-40 mm. Das Raumgewicht der Plattenelemente im Bereich von 200-500 kg/m3. Auch das Raumgewicht der einzelnen Platten kann unterschiedlich sein.In the ceiling plate according to the invention, at least two plate elements are provided. In this case, it is preferable to form the ceiling panel from two panel elements, ie from a room-side panel element and from a ceiling-side panel element. The thickness of the individual plates can either be the same or vary. The thickness of the individual plates is preferably in the range of 5-40 mm. The density of the plate elements in the range of 200-500 kg / m 3 . Also, the density of the individual plates may be different.

Die Deckenplatte der Erfindung wird aus Plattenelementen gebildet, die aus einem schalldämmenden Werkstoff bestehen. Derartige Plattenelemente sind an und für sich aus dem Stand der Technik bekannt und bestehen z.B. aus Mineralwolle und Bindemittel. Bezüglich der Mineralwolle sind übliche Mineralfasern im weitesten Sinne zu verstehen. Für die Herstellung der Plattenelemente können auch alle anderen, aus dem Stand der Technik bisher bekannten Werkstoffe, zur Herstellung von schalldämmenden Plattenelementen wie z.B. Perlite verwendet werden.The ceiling plate of the invention is formed of plate members made of a sound insulating material. Such plate elements are in themselves known from the prior art and consist e.g. made of mineral wool and binder. With regard to mineral wool, conventional mineral fibers are to be understood in the broadest sense. For the production of the plate elements, it is also possible to use all other materials known to date from the prior art for the production of sound-insulating plate elements, e.g. Perlite can be used.

Der Klebstoff, der erfindungsgemäß für die Herstellung der Klebstoffsperrschicht eingesetzt wird, ist bevorzugt ein anorganischer Klebstoff, es kann aber auch ein organischer Klebstoff eingesetzt werden.The adhesive which is used according to the invention for the production of the adhesive barrier layer is preferably an inorganic adhesive, but it is also possible to use an organic adhesive.

Die Erfindung wird nachfolgend anhand der Fig. 1 näher beschrieben.The invention will be described in more detail with reference to FIG. 1.

Fig. 1 zeigt die Ausführungsform einer erfindungsgemäßen Deckenplatte 1 die aus zwei Plattenelementen 6 und 7 gebildet ist. Die beiden Plattenelemente 6 und 7 bestehen jeweils aus einer 15 mm starken Mineralfaserplatte so daß sich eine Gesamtdicke von 30 mm ergibt. Die erfindungsgemäße Deckenplatte gemäß der Ausführungsform nach Fig. 1 weist an der raumseitigen Oberfläche 2 eine Feinlochung auf. Diese Feinlochung bildet nun die Vertiefungen und/oder Schallabsorptionsöffnungen, wie sie erfindungsgemäß vorgesehen sind. Die deckenseitige Oberfläche 3 ist glatt ausgeführt. Die Schalldämmsperrschicht 5 ist in der Ausführungsform nach Fig. 1 ein anorganischer Kleber.Fig. 1 shows the embodiment of a ceiling plate 1 according to the invention which is formed from two plate elements 6 and 7. The two plate elements 6 and 7 each consist of a 15 mm thick mineral fiber plate so that there is a total thickness of 30 mm. The ceiling panel according to the invention according to the embodiment of FIG. 1 has on the room-side surface 2 on a fine perforation. This fine perforation now forms the depressions and / or sound absorption openings, as they are provided according to the invention. The ceiling-side surface 3 is smooth. The sound damping barrier layer 5 in the embodiment according to FIG. 1 is an inorganic adhesive.

Das Deckenplattenelement nach der Fig. 1 weist zwei Plattenelemente 6, 7 auf, wobei das deckenseitige Plattenelement 6 ein höheres Raumgewicht als das raumseitige Plattenelement 7 besitzt. In Versuchen konnte gezeigt werden, daß ein derartiger Aufbau, d.h. ein Aufbau mit einzelnen Plattenelementen mit unterschiedlichen Raumgewichten sich positiv auf die Schalldämm- und Schallabsorptionseigenschaften auswirkt. Bei der Fig. 1 weist das Plattenelement 6 ein Raumgewicht von 280 kg/cm3 und das Plattenelement 7 ein Raumgewicht von 230 kg/m3 auf.The ceiling panel element according to FIG. 1 has two plate elements 6, 7, the ceiling-side plate element 6 having a higher density than the room-side plate element 7. In experiments it has been shown that such a structure, ie a structure with individual plate elements with different densities has a positive effect on the sound insulation and sound absorption properties. In Fig. 1, the plate member 6 has a density of 280 kg / cm 3 and the plate member 7 has a density of 230 kg / m 3 .

Bei der erfindungsgemäßen Deckenplatte ist besonders hervorzuheben, daß durch die Abfasung des deckenseitigen Plattenelements in Richtung der Decke das komplette Plattenelement näher am Tragprofil befestigt werden kann. Dadurch wird der Hohlraum zwischen Tragprofil und Plattenelement seitlich verringert, was sich günstig auf die Längsschalldämmung und Schallabsorption auswirkt.In the ceiling panel according to the invention is particularly noteworthy that the entire plate element can be attached closer to the support section by the chamfering of the ceiling-side plate member in the direction of the ceiling. As a result, the cavity between the support profile and plate member is laterally reduced, which has a favorable effect on the longitudinal sound insulation and sound absorption.
