Description
Die Erfindung betrifft eine schallabsorbierende Platte für die Raumgestaltung, mit einer Frontseite, in die mehrere Löcher für die Durchleitung von Schall zu einer rückseitig angeordneten Schicht aus schallabsorbierendem Material eingearbeitet sind.The invention relates to a sound absorbing plate for the Interior design, with a front in which several holes for the passage of sound to a rear arranged Layer of sound absorbing material are incorporated.

Der Erfindung liegt die Aufgabe zugrunde, eine Platte der genannten Art zu schaffen, bei welcher eine Holzoberfläche besser zur Geltung kommt und die dennoch eine hohe Absorptionsleistung im Hauptbereich der Tieftonabsorption gewährleistet. Die Platte soll vergleichsweise kostengünstig in Serie herstellbar sein. Zudem soll es möglich sein, die Platte so auszubilden, dass sie in Fluchträumen verwendbar ist, in denen hohe Brandschutzauflagen bestehen.The invention has for its object a plate of the above Way of creating a wooden surface better comes into its own and still has a high absorption capacity ensures low frequency absorption in the main area. The plate should be comparatively inexpensive to manufacture in series. In addition, it should be possible to design the plate so that it can be used in escape rooms where there are high fire protection requirements consist.
Die Aufgabe ist bei einer schallabsorbierenden Platte dadurch gelöst, dass frontseitig eine Deckschicht aus Holz oder holzähnlichem Werkstoff angeordnet ist und die genannten Löcher Mikroperforationen in dieser Deckschicht sind, wobei der Durchmesser dieser Mikroperforationen kleiner als 1,5 mm ist, dass hinter der Deckschicht eine tragende Schicht mit Durchgängen für die Schallaufnahme angeordnet ist und dass die Deckschicht und die tragende Schicht fest miteinander verbunden sind.The task with a sound absorbing panel is therefore solved that a front layer of wood or wood-like Material is arranged and the holes mentioned micro perforations are in this top layer, the diameter of these microperforations smaller than 1.5mm is that behind the top layer is a load-bearing layer with passages for the Sound recording is arranged and that the top layer and the supporting layer are firmly connected.
Bei der erfindungsgemässen Platte sind die Löcher Mikroperforationen, die beispielsweise durch Stanzen herstellbar sind und die eine Oberfläche eines Holzfurniers wesentlich weniger stören als die üblichen Nuten und Bohrungen. Das Holz der Platte ist vorzugsweise auf die frontseitig angeordnete Deckschicht reduziert. Da der Holzanteil gering ist, kann die schallabsorbierende Platte durch entsprechende Wahl der tragenden Schicht so hergestellt werden, dass sie auch hohen Brandschutzvorschriften entspricht. Die frontseitig angeordnete Deckschicht und die tragende Schicht sind fest miteinander verbunden. Aufgrund der geringen Stärke der Deckschicht kann diese sehr flexibel sein, und es ist möglich, auch gebogene schallabsorbierende Platten herzustellen.The holes in the plate according to the invention are microperforations, which can be produced for example by stamping and that interfere much less with a surface of a wood veneer than the usual grooves and bores. The wood of the plate is preferably reduced to the cover layer arranged on the front. Since the proportion of wood is low, it can be sound-absorbing Plate made by appropriate choice of the load-bearing layer be that they also have high fire safety regulations corresponds. The front layer and the load-bearing one Layer are firmly connected. Because of the low The thickness of the cover layer can be very flexible, and it is also possible to manufacture curved sound absorbing panels.
Nach einer Weiterbildung sind die Mikroperforationen Stanzungen, welche die Holzschicht durchdringen. Diese Stanzungen sind vorzugsweise zylindrische Durchbrüche. Die Durchbrüche können auch Bohrungen sein. Solche Durchbrüche können mit einem geeigneten Bohrer, Stanzwerkzeug oder mit einem Laser hergestellt werden. Sie können mit einem sehr kleinen Durchmesser, beispielsweise mit einem Durchmesser von lediglich 0,5 mm hergestellt werden. Solche Stanzungen sind dann in einem Abstand von beispielsweise 2 bis 3 m kaum sichtbar. Bei der erfindungsgemässen Platte dominiert die Holzstruktur und die Durchbrüche sind kaum noch wahrnehmbar.After further training, the micro perforations are die cuts, which penetrate the wood layer. These die cuts are preferred cylindrical breakthroughs. The breakthroughs can too Holes. Such breakthroughs can be made with a suitable one Drill, punch or laser can be made. You can use a very small diameter, for example with a diameter of only 0.5 mm. Such punchings are then at a distance of, for example 2 to 3 m hardly visible. Dominates in the plate according to the invention the wood structure and the openings are barely noticeable.
Die Stärke der Deckschicht ist vorzugsweise kleiner als 1,5 mm und liegt vorzugsweise im Bereich von 0,5 bis 1,0 mm. Eine solche Deckschicht kann beispielsweise aus einem mehrschichtigen Deckfurnier hergestellt werden.The thickness of the cover layer is preferably less than 1.5 mm and is preferably in the range of 0.5 to 1.0 mm. Such Top layer can for example consist of a multilayer Cover veneer can be made.
Die Platte kann dann besonders kostengünstig, leicht und unbrennbar hergestellt werden, wenn gemäss einer Weiterbildung der Erfindung die tragende Schicht zementgebunden ist. Das Trägermaterial kann dann ein Kunststoff, beispielsweise rezykliertes Polystyrol sein. Eine solche Platte ist dann besonders leicht und dennoch stabil. Die Verwendung von rezykliertem Kunststoff ist ökologisch sehr sinnvoll und vermindert zudem die Kosten für die Herstellung. Es hat sich gezeigt, dass eine Platte mit rezykliertem Polystyrol so stabil hergestellt werden kann, dass sie trittfest ist.The plate can then be particularly inexpensive, light and non-flammable are produced if, according to a training of the Invention the load-bearing layer is cement-bound. The carrier material can then be a plastic, for example recycled polystyrene his. Such a plate is then particularly light and nevertheless stable. The use of recycled plastic is ecologically very sensible and also reduces the costs for the Manufacturing. It has been shown that a plate with recycled Polystyrene can be made so stable that it is sure-footed.
Die Absorptionsleistung lässt sich erhöhen, wenn gemäss einer Weiterbildung der Erfindung in die tragende Schicht Vertiefungen eingearbeitet sind, die sich jeweils hinter den Mikroperforationen befinden. Diese Vertiefungen sind beispielsweise Nuten, die entsprechend auf die Mikroperforationen ausgerichtet sind. Hinter jeder Mikroperforation befindet sich somit eine Vertiefung in der tragenden Schicht. Diese Vertiefungen sind wesentlich breiter als die Mikroperforationen und können den Schall aufnehmen und an die tragende Schicht weitergeben.The absorption capacity can be increased if according to a Further development of the invention in the supporting layer depressions are incorporated, each behind the microperforations are located. These depressions are, for example, grooves that are aligned accordingly to the microperforations. Behind each micro perforation is thus a recess in the load-bearing layer. These specializations are essential wider than the micro perforations and can absorb the sound and pass it on to the load-bearing layer.
Die tragende Schicht und die Deckschicht sind gemäss einer Weiterbildung miteinander verklebt oder verleimt. Rückseitig der tragenden Schicht ist vorzugsweise eine weitere Platte mit Durchbrüchen, beispielsweise eine Hartfaserplatte, aufgebracht, vorzugsweise aufgeklebt oder aufgeleimt. Dieser sandwichartige Aufbau ermöglicht auch die Herstellung einer an sich beliebig gebogenen Platte. Dazu werden nach einem erfindungsgemässen Verfahren die Schichten sowie Klebe- oder Leimschichten sandwichartig aufeinandergelegt und in einer Formpresse zu der gewünschten gebogenen Form verpresst. Die tragende Schicht kann hierbei wie die Deckschicht flexibel und biegbar sein. Dies ist insbesondere dann der Fall, wenn die tragende Schicht aus rezykliertem Polystyrol besteht, das mit Zement gebunden ist. Das Polystyrol besteht hierbei aus unterschiedlich grossen Partikeln, zwischen denen Durchgänge bestehen. Durch diese Durchgänge kann der Schall auf die Rückseite der Platte hindurchtreten. Messungen haben ergeben, dass eine solche Platte hauptsächlich im Tieftonbereich absorbiert. Wesentlich ist auch, dass infolge der Stabilität der schallabsorbierenden Platte diese ohne Rahmen verwendet werden kann. Sie kann damit eigentlich wie eine massive Holzplatte verwendet werden, wobei sie jedoch wesentlich leichter und selbstverständlich schallabsorbierend ist.The load-bearing layer and the top layer are according to a further training glued or glued together. On the back of the supporting layer is preferably a further plate Breakthroughs, for example a hardboard, applied, preferably glued or glued. That sandwich Structure also allows the production of any in itself curved plate. For this purpose, according to a method according to the invention the layers as well as adhesive or glue layers sandwiched placed on top of each other and in a molding press to the desired one curved shape pressed. The load-bearing layer can be like the cover layer should be flexible and bendable. This is particularly so then the case when the supporting layer is made of recycled polystyrene exists that is bound with cement. The polystyrene consists of different sized particles, between which passages exist. Through these passages, the Step sound through the back of the plate. Measurements have shown that such a record mainly in the low frequency range absorbed. It is also essential that due to the stability the sound absorbing panel used without a frame can be. It can actually be like a massive one Wood panel can be used, but it is much lighter and of course it is sound absorbing.

ein mehrschichtiges Sperrholz. Die Stärke der Membran 2 ist vorzugsweise
kleiner als 1,5 mm und liegt vorzugsweise im Bereich
von 0,5 bis 1,0 mm. Die Membran 2 ist in regelmässiger oder unregelmässiger
Anordnung mit einer Vielzahl von durchgehenden
Perforationen 5 versehen. Diese Perforationen 5 bilden vorzugsweise
zylindrische Löcher mit einem Durchmesser kleiner als
1,5 mm. Vorzugsweise liegt der Durchmesser der Perforationen 5
im Bereich von 0,1 bis 1,1 mm. Diese Perforationen 5 besitzen
beispielsweise einen Raster von 5 mm, wenn die Perforationen gemäss
Figur 1 in Reihen angeordnet sind. Diese Reihen können jedoch
auch versetzt sein und es ist auch denkbar, die Perforationen
5 unregelmässig verteilt anzuordnen. In der Regel ist mit
einer Ausnahme eines Randes 9a die gesamte Oberfläche 9 perforiert.
Denkbar sind jedoch auch Ausführungen, bei denen gemäss
Figur 1 lediglich ein Teilbereich der Oberfläche 9 perforiert
ist. Die Perforationen 5 werden vorzugsweise mit einem geeigneten
Stanzwerkzeug hergestellt. Denkbar ist jedoch auch eine Herstellung
mit einem anderen geeigneten Werkzeug, beispielsweise
einem Laser. The
Die Membran 2 ist mit der tragenden Schicht 3 fest verbunden,
insbesondere verklebt oder verleimt. Diese tragende Schicht 3
besteht gemäss Figur 4 aus unregelmässigen, unterschiedlich
grossen Teilen 12, die aus einem vorzugsweise leichten Material
bestehen. Das Material ist vorzugsweise ein rezyklierter Kunststoff,
beispielsweise Polystyrol. Die Teile 12 sind in Zement 14
gebunden. Im Zement 14 befinden sich unregelmässig verteilt
Durchgänge 15, durch welche der Schall von der Oberfläche 9 der
Platte 1 auf die Rückseite 10 geleitet werden kann. Um die Einleitung
des Schalles in die tragende Schicht 3 zu erhöhen, ist
vorgesehen, in die tragende Schicht 3 Ausnehmungen 6, beispielsweise
V-förmige Nuten einzuarbeiten, die jeweils hinter den Perforationen
5 angeordnet sind. Der beispielsweise in Richtung des
Pfeils 11 einfallende Schall gelangt dann durch die Perforationen
5 in die Ausnehmungen 6 und von diesen in die Durchgänge 15
und schliesslich auf die Rückseite 10 der Platte. Die Durchgänge
6 sind, wie ersichtlich, breiter als die Perforationen 5 und
erhöhen damit die Fläche, über welche der Schall in die tragende
Schicht 3 eingeleitet werden kann.The
Die tragende Schicht 7 ist nicht brennbar. Im Brandfall schmelzen
die Teile 12, die Struktur der tragenden Schicht 3 bleibt
jedoch erhalten. Da die Membran 5 sehr dünn und damit der
Holzanteil klein ist, eignet sich die Platte 1 auch für die Auskleidung
in Fluchträumen.The supporting
Rückseitig an der tragenden Schicht 3 ist eine Schicht 4 angeordnet,
die beispielsweise eine dünne Hartfaserplatte ist und
die Durchbrüche 7 aufweist. Die Schicht 4 ist vorzugsweise ebenfalls
mit der tragenden Schicht verleimt oder verklebt.A
Zur Herstellung der Platte 1 werden die Membran 2, die tragende
Schicht 3 sowie die Schicht 4 geleimt und sandwichartig aufeinandergelegt.
Rückseitig an der Schicht 4 kann gemäss Figur 1
noch ein Vlies 4 befestigt werden. Die aufeinandergelegten
Schichten werden in einer Formpresse miteinander verpresst. Nach
dem Verpressen sind die Schichten miteinander verbunden und damit
die Platte stabil. Da die Schichten flexibel und biegbar
sind, können diese auch zu einer gebogenen Platte verpresst werden.
Beispielsweise zeigt die Figur 1 eine gebogene Platte, die
sich beispielsweise als Absorber und gleichzeitig Lichtreflektor
eignet. Die erfindungsgemässe Platte 1 kann beispielsweise als
Decken- oder Wandverkleidung verwendet werden. Weitere Anwendungen
sind Türen- und Schranktürverkleidungen sowie freistehende
Paravents.To manufacture the
