Description

Die Erfindung betrifft eine schallabsorbierende Platte für die Raumgestaltung, mit einer Mehrzahl von Durchbrüchen, die durch parallele Nuten auf der Sichtseite der Platte und Ausnehmungen auf der Rückseite der Platte gebildet werden.The invention relates to a sound absorbing plate for the interior design, with a number of breakthroughs, by parallel grooves on the visible side of the plate and Recesses are formed on the back of the plate.

Eine schallabsorbierende Platte dieser Art ist im Stand der Technik aus der FR-A-1.015.972 bekannt geworden. Diese Schrift zeigt in Figur 4 eine schallabsorbierende Platte, in die auf der Sichtseite und der Rückseite Nuten eingearbeitet sind. Die Nuten der Sichtseite und der Rückseite verlaufen quer zueinander und schneiden sich, derart, dass an den Schnittstellen Durchbrüche vorhanden sind.A sound absorbing plate of this type is in the prior art Technology from FR-A-1.015.972 known. This Scripture shows in Figure 4 a sound absorbing plate, incorporated into the grooves on the visible side and the back are. The grooves on the visible side and the back are transverse to each other and intersect in such a way that Breakthroughs are present at the interfaces.

Aus der GB-A-530,029 ist eine schallabsorbierende Platte offenbart, die auf der Sichtseite Nuten und auf der Rückseite Bohrungen aufweist. Die Bohrungen schneiden die Nuten und bilden kreisförmige Durchbrüche.GB-A-530,029 is a sound absorbing panel reveals the grooves on the visible side and on the back Has holes. The holes cut the grooves and form circular openings.

Weiter offenbart die EP-A-0 388 355 eine schallabsorbierende Platte, bei welcher die Nuten der Sichtseite V-Nuten sind. Auf der anderen Seite sind ebenfalls V-Nuten oder Bohrungen eingearbeitet.Furthermore, EP-A-0 388 355 discloses a sound absorbing Plate in which the grooves on the visible side are V-grooves are. On the other side there are also V-grooves or Drilled holes.

Bei den genannten schallabsorbierenden Platten besteht ein wesentlicher Effekt darin, dass ein Anteil der auftreffenden Schallenergie absorbiert, aber nicht mehr reflektiert wird. Zur Verbesserung der Schallabsorption wird in vielen Fällen hinter der Platte eine schallabsorbierende Matte angeordnet. In vielen Fällen ist es jedoch nicht möglich, eine solche Matte anzubringen und die schallabsorbierende Platte wird dann direkt auf der Gebäudewand befestigt. In diesem Fall kann ein Teil des Schalls an der Gebäudewand reflektiert und durch die Durchbrüche der Platte wieder in den Raum zurückgeworfen werden. Die Schallabsorption kann in diesem Fall ungenügend sein.In the aforementioned sound absorbing panels there is a essential effect in that a portion of the incident Sound energy absorbed but no longer reflected becomes. To improve sound absorption is used in many A sound absorbing mat is arranged behind the panel. In many cases, however, it is not possible to get one attach such a mat and the sound absorbing The plate is then attached directly to the building wall. In In this case, some of the sound can be heard on the building wall reflected and in through the breakthroughs of the plate the room be thrown back. The sound absorption can be insufficient in this case.

Der Erfindung liegt die Aufgabe zugrunde, eine schallabsorbierende Platte zu schaffen, die sich durch eine bessere Schallabsorption auszeichnet und die dennoch kostengünstig herstellbar ist.The invention has for its object a sound absorbing To create plate that stands out for better Excellent sound absorption and yet inexpensive can be produced.

Die Aufgabe ist bei einer schallabsorbierenden Platte der genannten Gattung dadurch gelöst, dass die Ausnehmungen auf der Rückseite der Platte gefräste Langlöcher sind.The task is with a sound absorbing plate mentioned genre solved in that the recesses on milled slots on the back of the plate.

Es hat sich gezeigt, dass solche gefräste Langlöcher eine noch bessere Schallaufnahme besitzen als Nuten oder Bohrungen. Diese Schallabsorption kann noch weiter verbessert werden, indem die Seitenflächen der Langlocher uneben ausgebildet werden. Beispielsweise können solche Unebenheiten in einfacher Weise durch die Verwendung eines Schruppfräsers hergestellt werden. Die Langlöcher weisen dann an ihren Seitenflächen parallele Rillen auf. Diese Rillen haben die Wirkung, dass der in diese Langlöcher eingedrungene Schall mehrfach reflektiert und dadurch vernichtet wird. Die Schallenergie wird dabei in Wärme umgewandelt. Eine solche schallabsorbierende Platte weist auch dann eine hinreichende Schallabsorption auf, wenn sie direkt an der Gebäudewand und somit ohne Dämmschicht montiert wird. Wesentlich ist auch, dass mit Fräsungen auf der Rückseite, verglichen mit Bohrungen, ein offenerer Raum erreicht wird, der eine höhere Schallabsorption gewährleistet. Ferner lassen sich mit einem solchen Schruppfräser solche Langlöcher mit wesentlich höherer Leistung und geringerem Kraftaufwand und damit kleineren Kosten herstellen. Schliesslich ist noch wesentlich, dass bei der erfindungsgemässen Platte die Durchbrüche keine Kreisabschnitte bilden. Die Durchbrüche können bei quer verlaufenden Fräsungen Rechtecke bilden, die ein wesentlich anderes Lochbild ergeben als Bohrungen.It has been shown that such milled slots are a have even better sound absorption than grooves or bores. This sound absorption can be further improved are made uneven by the side surfaces of the oblong holes become. For example, such bumps in a simple way by using a roughing cutter getting produced. The slots then point to theirs Parallel grooves on the side surfaces. Have these grooves the effect that the penetrated into these elongated holes Sound is reflected several times and is thereby destroyed. The sound energy is converted into heat. A such a sound-absorbing plate also has an adequate one Sound absorption when placed directly on the building wall and is therefore installed without an insulation layer. Essential is also that compared to millings on the back with holes, a more open space is reached which ensures a higher sound absorption. Let also such elongated holes with such a roughing cutter with much higher performance and less effort and thus produce lower costs. Finally is still essential that in the plate according to the invention Breakthroughs do not form circular sections. The breakthroughs can form rectangles with transverse milling, which result in a hole pattern that is significantly different from that of holes.

Die schallabsorbierende Platte ist auch in ästhetischer Hinsicht vorteilhaft, insbesondere ist eine gut schallabsorbierende Platte mit einem geringen Anteil an offener Fläche möglich. Dieser Anteil kann unter 4% liegen. Die Nuten auf der Sichtseite sind vorzugsweise V-Nuten. Durch diese Nuten wird der Schall gebündelt und zu den Durchbrüchen geleitet. Es entsteht ein sogenannter Sogeffekt. Durch die V-förmigen Nuten auf der Sichtseite der Platte wird insbesondere die Schallaufnahme von Schallquellen verbessert, die einen ungünstigen Winkel zur Absorptionsfläche aufweisen. Mit V-förmigen Nuten wird eine sehr feine Gliederung der Rillen erreicht und die Durchbrüche erscheinen als schmale Schlitze, die ein neues und einzigartiges Gestaltungselement bilden.The sound absorbing plate is also more aesthetic In terms of advantage, in particular is a good sound absorbing Plate with a small amount of open Area possible. This proportion can be less than 4%. The grooves V grooves are preferably on the visible side. By these grooves bundle the sound and become the breakthroughs headed. There is a so-called suction effect. By the V-shaped grooves on the visible side of the plate especially improves the sound absorption of sound sources, which is an unfavorable angle to the absorption surface exhibit. V-shaped grooves create a very fine structure the grooves are reached and the breakthroughs appear as narrow slits, which is a new and unique design element form.

Schallmessungen haben gezeigt, dass bei einer erfindungsgemässen Platte mit einem freien Lochanteil von 5%, einem rückseitig aufkaschierten Akustikvlies und einem Abstand vom Hallraumboden von 350 mm im Bereich von 125 bis 4000 Hz ein überraschend konstanter Schallabsorptionsgrad von etwa 0,6 erreicht wird.Sound measurements have shown that in a Plate with 5% free hole, one acoustic fleece laminated on the back and a gap from the reverberation room floor of 350 mm in the range from 125 to 4000 Hz a surprisingly constant sound absorption level of around 0.6 is reached.

    • Die in den Figuren 1 und 2 gezeigte schallabsorbierende Platte 1 ist beispielsweise eine Holzfaserplatte oder Gipsfaserplatte oder auch ein anderer, vorzugsweise schwer entflammbarer Werkstoff. Sie ist vorzugsweise rechteckig und weist zu Ihrer Verbindung mit weiteren Platten 1 Verbindungsmittel 13, beispielsweise Federn und Nuten, auf. Die Platte 1 kann auch mit einem Rahmen an einer Gebäudewand montiert werden.The sound absorbing shown in Figures 1 and 2 Panel 1 is, for example, a wood fiber board or gypsum fiber board or another, preferably flame-retardant Material. It is preferably rectangular and assigns 1 lanyard to your connection to other panels 13, for example tongues and grooves. The Panel 1 can also have a frame on a building wall to be assembled.

    In die Sichtseite 8 sind mehrere parallel verlaufende und sich über die ganze Länge der Platte 1 erstreckende Nuten 7 eingearbeitet. Diese Nuten 7 sind vorzugsweise V-Nuten. In die Rückseite der Platte 1 sind Langlöcher 9 eingearbeitet, die Fräsungen sind. Die Langlöcher 9 erstrecken sich in Längsrichtung der Nuten 7 und schneiden diese, derart, dass schlitzförmige, vergleichsweise schmale Durchbrüche 4 gebildet sind. Die Langlöcher 9 sind vorzugsweise versetzt angeordnet, so dass sich das in Figur 2 gezeigte Bild der Durchbrüche 4 ergibt.In the visible side 8 are several parallel and grooves 7 extending over the entire length of the plate 1 incorporated. These grooves 7 are preferably V-grooves. In the back of the plate 1, slots 9 are incorporated, the millings are. The elongated holes 9 extend in Longitudinal direction of the grooves 7 and cut them, such that slit-shaped, comparatively narrow openings 4 are formed are. The elongated holes 9 are preferably offset arranged so that the image shown in FIG Breakthroughs 4 results.

    Die Langlöcher 9 werden vorzugsweise mit einem Schruppfräser gefräst. In den Seitenwandungen der Langlöcher 9 entstehen dadurch Rillen 11, die wesentlich zur Schallabsorption beitragen. Wie die Figur 1 zeigt, gelangt der Schall beispielsweise in Richtung des Pfeils 14 auf die Sichtseite 8 der Platte 1. An den Seitenwänden der Nuten 7 wird dann der Schall in Richtung des Pfeiles 15 in die Langlöcher 9 reflektiert. In diesen wird der Schall an den Flanken 11a der Rillen 11 mehrfach reflektiert bzw. gestreut, wie dies mit den Pfeilen 16 angedeutet ist. Der Schall wird damit in den Langlöchern 9 mehrfach reflektiert bzw. gestreut und verliert Energie, die als Wärme abgegeben wird. Die Rillen 11 können auch andere Unebenheiten sein, die ebenfalls mit einem geeigneten Fräser herstellbar sind.The elongated holes 9 are preferably with a roughing cutter milled. In the side walls of the elongated holes 9 arise thereby grooves 11, which are essential for sound absorption contribute. As shown in Figure 1, the sound arrives for example in the direction of arrow 14 on the visible side 8 of the plate 1. 7 on the side walls of the grooves then the sound in the direction of arrow 15 in the elongated holes 9 reflected. In these the sound is on the flanks 11a of the grooves 11 are reflected or scattered several times, as indicated by the arrows 16. The sound will thus reflected or scattered several times in the elongated holes 9 and loses energy that is given off as heat. The grooves 11 can also be other bumps that can also be produced with a suitable milling cutter.

    Die Figuren 3 und 4 zeigen Platten 2, bei denen sich die Langlöcher 9 quer zu den Nuten 7 erstrecken. Es entstehen dadurch etwas kürzere Durchbrüche 5, die aber ebenfalls vorzugsweise lang und schmal sind. Die Fräsungen haben hier den Vorteil, dass mit einer Fräsung gleichzeitig mehrere Durchbrüche 5 geschaffen werden. Dadurch ergibt sich eine sehr rationelle Herstellung. Auch hier sind die Nuten 7 vorzugsweise V-Nuten. Die Durchbrüche 5 bzw. 6 sind dann vergleichsweise schmal und visuell nicht auffällig. Die Figur 5 zeigt die Platte 1, die an der Unterseite einer Matte 12 angeordnet ist. Diese Matte 12 besteht aus einem geeigneten Dämmmaterial und liegt an der hier nicht gezeigten Gebäudewand an. Eine solche Matte 12 kann in vielen Fällen nicht montiert werden. Die Platte 1 liegt in diesen Fällen direkt an der hier nicht gezeigten Gebäudewand an. In diesem Fall ist die Schallabsorption in den Langlöchern 9 besonders wichtig, da eine Gebäudewand in der Regel Schall gut reflektiert.Figures 3 and 4 show plates 2, in which the Extend elongated holes 9 transversely to the grooves 7. Arise thereby slightly shorter openings 5, but also are preferably long and narrow. The millings have here the advantage that with one milling several at the same time Breakthroughs 5 are created. This results in a very rational production. Here too the grooves are 7 preferably V-grooves. The breakthroughs 5 and 6 are then comparatively narrow and not visually noticeable. The figure 5 shows the plate 1 on the underside of a mat 12 is arranged. This mat 12 consists of a suitable one Insulation material and is due to the one not shown here Building wall. Such a mat 12 can in many cases not be assembled. The plate 1 lies in these cases directly on the building wall, not shown here. In this In this case, the sound absorption in the elongated holes 9 is special important because a building wall is usually sound well reflected.

    Die Figur 6 zeigt die Anordnung der Nuten 7 auf der Sichtseite 8 der Platte 1. Diese Anordnung ergibt sich auch bei den Platten 2 und 3. Die Langlöcher 9 sind hier nicht sichtbar.FIG. 6 shows the arrangement of the grooves 7 on the visible side 8 of the plate 1. This arrangement also results in the plates 2 and 3. The slots 9 are not here visible.

    Die Herstellung der Platte 1 erfolgt vorzugsweise mit einem mehrspindlingen Fräser, was ein sehr rationelles Arbeiten erlaubt, insbesondere wenn die Fräser Schruppfräser sind.The plate 1 is preferably produced with a multi-spindle milling cutter, which is a very efficient work allowed, especially if the cutters are roughing cutters.
