Description

Die Erfindung betrifft eine Holzbautafel für Decken oder Wände eines Raumes, die

  • Zwischenräume zur Aufnahme von Schallabsorptionsmaterial,
  • zumindest eine, die Zwischenräume für das Schallabsorptionsmaterial aufweisende Trägerschicht, sowie
  • eine in Gebrauchslage dem Raum zugewandte und mit, bis zu den das Schallabsorptionsmaterial aufweisenden Zwischenräumen der Trägerschicht erstreckenden Öffnungen versehene Sichtlage hat,
wobei die das Schallabsorptionsmaterial aufweisenden Zwischenräume der Trägerschicht kreuzweise zu den Öffnungen der Sichtplatte angeordnet sind.The invention relates to a wooden panel for ceilings or walls of a room, the
  • Spaces for receiving sound absorption material,
  • at least one, the spaces for the sound absorbing material having carrier layer, and
  • has a view in the position of use facing the room and with up to the sound absorption material having interstices of the support layer extending openings provided,
wherein the sound absorbing material having interstices of the carrier layer are arranged crosswise to the openings of the face plate.

Aus der DE 20 2004 010 276 U 1 ist bereits eine Holzbautafel der eingangs erwähnten Art bekannt, die an den Decken oder Wänden eines Raumes montiert werden kann, um dort eine verbesserte Schallabsorption zu erzielen. Die vorbekannte Holzbautafel hat eine Trägerschicht, die zumindest eine, wenigstens teilweise durch rostartig angeordnete und voneinander beabstandete Leisten oder gleichen Einzelelemente gebildete Schicht aufweist. In den zwischen benachbarten Einzelelementen gebildeten Zwischenräumen ist Schallabsorptionsmaterial vorgesehen, das beispielsweise aus einer leistenförmig zugeschnittenen Weichfaserplatte hergestellt sein kann. Die Trägerschicht der vorbekannten Holzbautafel ist mit einer in Gebrauchslage dem Raum zugewandten Sichtplatte verbunden, die nach dem Verbinden mit der Trägerschicht mit Öffnungen versehen werden, welche kreuzweise zu den das Schallabsorptionsmaterial aufweisenden Zwischenräumen orientiert sind. Diese, in die Sichtplatte einzuarbeitenden Öffnungen können in ihrem Abstand zueinander und/oder in ihrer Schlitzbreite völlig unabhängig von den in der Trägerschicht angeordneten Zwischenräumen angeordnet werden, ohne dass die Zugänglichkeit und die schallschluckende beziehungsweise schalldämmende Wirkung des in den Zwischenräumen der Trägerschicht vorgesehenen schallabsorbierenden Materials beeinträchtigt würde. Da die in die Sichtplatte eingearbeiteten Schlitzöffnungen einerseits und die Zwischenräume in der Trägerschicht andererseits und damit auch die zwischen den Schlitzöffnungen beziehungsweise zwischen den Zwischenräumen verbleibenden Holzleisten kreuzweise zueinander angeordnet sind, ist selbst bei einem nur zweischichtigen Aufbau dieser vorbekannten Holzbautafel stets eine ausreichende Stabilität dieses selbsttragenden Konstruktionselementes sichergestellt. Die vorbekannten Holzbautafel kann daher ohne Einschränkungen auf die Stabilität oder schallabsorbierende Wirkung vergleichsweise dünn ausgestaltet werden.From the DE 20 2004 010 276 U 1 is already a wooden panel of the type mentioned above, which can be mounted on the ceilings or walls of a room to achieve there improved sound absorption. The previously known wooden building board has a carrier layer, the at least one, at least partially arranged by rust and from each other having spaced strips or the same individual elements formed layer. In the intermediate spaces formed between adjacent individual elements sound absorbing material is provided, which may be made for example of a strip-shaped cut softboard. The carrier layer of the previously known wooden building board is connected to a viewing panel which faces the room in the position of use and, after being connected to the carrier layer, is provided with openings which are oriented crosswise to the spaces containing the sound absorption material. These, to be incorporated into the face plate openings can be arranged at a distance from each other and / or in their slot width completely independent of the arranged in the carrier layer spaces without impairing the accessibility and the sound-absorbing or sound-absorbing effect of provided in the interstices of the carrier layer sound-absorbing material would. Since the incorporated in the face plate slot openings on the one hand and the interstices in the carrier layer on the other hand and thus the remaining between the slot openings or between the interstices wooden strips are arranged crosswise to each other, even with a only two-layer structure of this prior art timbers is always a sufficient stability of this self-supporting structural element ensured. The previously known wooden building board can therefore be configured comparatively thin without any restrictions on the stability or sound-absorbing effect.

Die aus DE 20 2004 010 276 U 1 vorbekannte Holzbautafel kann eine Sichtplatte haben, die je nach gewünschter Optik bezüglich Material, Farbe und/oder Oberflächengestaltung individuell ausgebildet werden kann. Ebenso können die das Schallabsorptionsmaterial freilegenden Öffnungen individuell in die Sichtplatte eingebracht werden. Da die Sichtplatte zunächst geschlossen ausgebildet ist und erst vor der Montage mit Öffnungen gemäß dem Wunsch des Anwenders versehen wird, kann ein großer Vorrat gleichartiger Holzbautafeln vorgehalten werden, sodass lange Lieferzeiten, die durch individuelle Anfertigung der gesamten Holzbautafel entstehen können, vermieden sind.From DE 20 2004 010 276 U 1 Previously known timber board may have a faceplate, which can be designed individually depending on the desired appearance in terms of material, color and / or surface design. Likewise, the openings exposing the sound absorbing material can be individually incorporated into the Visible plate are introduced. Since the sight plate is initially formed closed and is provided only with openings in accordance with the wishes of the user before installation, a large supply of similar wooden boards can be kept, so long delivery times, which can be caused by individual production of the entire timber board, are avoided.

Die vorbekannte Holzbautafel kann daher in vielfältiger Weise in einer ästhetisch ansprechenden Optik hergestellt werden.The previously known wooden building board can therefore be produced in a variety of ways in an aesthetically pleasing appearance.

Es besteht jedoch die Aufgabe, eine Holzbautafel der eingangs erwähnten Art zu schaffen, die sich durch verbesserte schalldämmende und/oder schallschluckende Eigenschaften auszeichnet, ohne dass deshalb eine demgegenüber verschlechterte Optik in Kauf genommen werden müsste.However, there is the object to provide a wooden panel of the type mentioned, which is characterized by improved sound-absorbing and / or sound-absorbing properties, without therefore a contrast deteriorated optics would have to be accepted.

Eine erfindungsgemäße Lösung dieser Aufgabe besteht bei der Holzbautafel der eingangs erwähnten Art insbesondere darin, dass die Sichtlage auf ihrer dem Raum zugewandten Sichtseite eine zur diffusen Streuung des reflektierten Schalls stark strukturierte Oberfläche hat.A solution to this problem according to the invention in the case of the wooden construction panel of the type mentioned in the introduction is, in particular, that the visual position has a surface which is highly structured on its visible side facing the room and has a strongly structured surface for the diffuse scattering of the reflected sound.

Bei der erfindungsgemäßen Holzbautafel weist die Sichtlage auf ihre dem Raum zugewandten Sichtseite eine zur diffusen Streuung des reflektierten Schalls stark strukturierte Oberfläche auf. Durch die starke Oberflächenstruktur auf der Sichtseite der erfindungsgemäßen Holzbautafel wird nicht nur eine lebendige und ästhetisch ansprechende Optik begünstigt, - durch die stark strukturierte Oberfläche lässt sich vielmehr auch eine diffuse Streuung des reflektierten Schalls erreichen, wodurch die Sprachverständlichkeit und der musikalische Hörgenuss wesentlich verbessert werden kann, weil sich alle Frequenzen optimal im Raum verteilen.In the case of the timber building board according to the invention, the viewing position has a surface which is strongly structured for the diffuse scattering of the reflected sound on its visible side facing the room. Due to the strong surface structure on the visible side of the wooden building board according to the invention, not only a lively and aesthetically pleasing appearance is favored, but also a diffuse scattering of the reflected sound can be achieved by the strongly structured surface, whereby the speech intelligibility and the musical listening pleasure can be substantially improved because all frequencies are distributed optimally in the room.

Dabei lässt sich das lebendige Erscheinungsbild der erfindungsgemäßen Holzbautafel noch erheblich verbessern, wenn die Sichtlage eine durch hervorstehende Jahresringe und durch demgegenüber zurückgesetzte Jahresring-Zwischenräume stark strukturierte Oberfläche hat, und wenn somit das natürliche Holzbild auf diese Weise stärker hervortritt.In this case, the living appearance of the wooden building board according to the invention can be significantly improved if the visual position has a strongly structured by projecting annual rings and by contrast recessed annual ring spaces, and thus if the natural wood appearance in this way more prominent.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass die Sichtlage auf ihrer dem Raum zugewandten Sichtseite eine gebürstet und/oder gestrahlte Oberflächenstruktur hat. Da die Holzoberfläche im Bereich der Jahresringe eine verdichtete Struktur hat, während sie im Bereich der Jahresring-Zwischenräume eher weicher ist, lässt sich durch Bürsten oder Strahlen mit einem abrasiven Strahlmittel, wie zum Beispiel Sandstrahlen, auf einfache Weise eine stark strukturierte Oberfläche erzeugen, die sich durch hervorstehende Jahresringe und durch demgegenüber zurückgesetzte Jahresring-Zwischenräume auszeichnet.A preferred embodiment according to the invention provides that the visual position on its side facing the room has a brushed and / or blasted surface structure. Since the wood surface in the area of the annual rings has a compacted structure, while it is rather softer in the area of the annual ring gaps, by brushing or blasting with an abrasive blasting abrasive, such as sandblasting, can easily create a highly textured surface, the characterized by protruding annual rings and by contrast recessed annual ring gaps.

Ein weiterer Vorschlag zur Lösung der oben gestellten Aufgabe von eigener schutzwürdiger Bedeutung sieht bei der Holzbautafel der eingangs erwähnten Art vor, dass zusätzlich zu oder statt der sichtseitig stark strukturierten Oberfläche wenigstens eine größere Anzahl der in der Sichtlage vorgesehenen Öffnungen bis tief in das Schallabsorptionsmaterial reichen. Während bei dem eingangs erwähnten Stand der Technik die Öffnungen stets nur bis zur Oberfläche des Schallabsorptionsmaterials fortgeführt wurden, reichen bei der erfindungsgemäßen Holzbautafel die Öffnungen bis tief in das Schallabsorptionsmaterial. Diese derart tief in das Schallabsorptionsmaterial reichenden Öffnungen haben eine optische Tiefenwirkung, die das Erscheinungsbild der erfindungsgemäßen Holzbautafel wesentlich verbessert; entscheidend ist aber, dass diese tief in das Schallabsorptionsmaterial reichenden Öffnungen sich auch durch eine verbesserte schallabsorbierende Wirkung auszeichnen. Durch diese vertiefte Ritzung der Sichtlage können nämlich die in die Öffnungen eindringenden Schallwellen auch seitlich beziehungsweise horizontal in das hinter der Sichtlage befindliche Schallabsorptionsmaterial der Trägerschicht vorstoßen.A further proposal for solving the above object of its own worthy worth protection provides in the timbers of the type mentioned above that in addition to or instead of the visible heavily textured surface at least a larger number of openings provided in the visual position to deep into the sound absorption material. While in the above-mentioned prior art, the openings have always been continued only to the surface of the sound absorption material, the openings extend in the timber panel according to the invention deep into the sound absorption material. These openings reaching into the sound absorption material so deeply have an optical depth effect which substantially improves the appearance of the wood building board according to the invention; but it is crucial that these openings reach deep into the sound absorbing material also distinguished by an improved sound-absorbing effect. By virtue of this recessed scratching of the visual position, the sound waves penetrating into the openings can also project laterally or horizontally into the sound absorption material of the carrier layer located behind the viewing position.

Mit jedem der beiden oben beschriebenen Vorschläge lässt sich auch bei geringer Dicke der erfindungsgemäßen Holzbautafel und insbesondere ihrer Sichtlage eine besonders hohe Schallabsorption erreichen, was insbesondere bei edlen und hochwertigen Sichtlagen zu einer Materialersparnis und damit zu einer Kostenreduktion führen kann. Durch die erreichbaren hohen Schallabsorptionswerte können aber bei Bedarf auch Mengeneinsparungen bei der gesamten Absorberfläche oder bessere Absorptionswerte bei gleicher Fläche erzielt werden. Diese verbesserten Absorptionswerte sind auch mit dünneren beziehungsweise leichteren und entsprechend handlichen Holzbautafeln, beispielsweise im Holz-Innenausbau, erreichbar.With each of the two proposals described above, a particularly high sound absorption can be achieved even with a small thickness of the wooden building board according to the invention and in particular its visual position, which can lead to a saving of material and thus to a cost reduction, especially in noble and high-quality viewing. Due to the achievable high sound absorption values, however, it is also possible, if required, to achieve quantity savings over the entire absorber surface or better absorption values for the same area. These improved absorption values can also be achieved with thinner or lighter and correspondingly handy wooden building panels, for example in wood interior construction.

Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass die sich tief in das Schallabsorptionsmaterial erstreckenden Öffnungen zumindest über die Hälfte der Dicke oder Längserstreckung des Schallabsorptionsmaterials reichen.In this case, a preferred embodiment according to the invention provides that the openings extending deep into the sound absorption material extend at least over half the thickness or longitudinal extension of the sound absorption material.

Vorteilhaft ist es, wenn die Trägerschicht als eine flächig durchgehende Schicht aus einander abwechselnden Latten oder dergleichen Einzelelementen einerseits und Schallabsorptionsmaterial andererseits gebildet ist. Eine bevorzugte Ausführungsform gemäß der Erfindung sieht daher vor, dass die Trägerschicht aus zumindest einer ersten Schicht voneinander beabstandeter und/oder parallel zueinander angeordneter Latten oder dergleichen Einzelelemente gebildet ist und dass wenigstens in einer größeren Anzahl der zwischen den von einander beabstandeten Einzelelementen gebildeten Zwischenräumen das vorzugsweise lattenförmig zugeschnittene Schallabsorptionsmaterial angeordnet ist, und dass das Schallabsorptionsmaterial an den benachbarten Längsseiten der einen Zwischenraum begrenzenden Einzelelemente anliegen.It is advantageous if the carrier layer is formed as a flat continuous layer of alternating slats or similar individual elements on the one hand and sound absorption material on the other.

In den Fig. 1 bis 12 sind verschiedene Ausführungen 1, 2 und 3 einer Holzbautafel dargestellt, die als Akustikelement und insbesondere als Akustikpaneel ausgebildet und zur Montage an den Decken und/oder Wänden eines Raumes bestimmt ist.In the Fig. 1 to 12 Different versions 1, 2 and 3 of a wooden building board are shown, which is designed as an acoustic element and in particular as an acoustic panel and intended for mounting on the ceilings and / or walls of a room.

Die hier gezeigten Holzbautafeln 1, 2, 3 weisen Zwischenräume 4 auf, von denen zumindest eine Teilmenge mit Schallabsorptionsmaterial 5 versehen ist. Das Schallabsorptionsmaterial 5, das vorzugsweise aus einer insbesondere leistenförmig zugeschnittenen Holz-Weichfaserplatte hergestellt sein kann, füllt hier die Zwischenräume 4 vollständig aus.The timber building panels 1, 2, 3 shown here have gaps 4, of which at least a subset is provided with sound absorption material 5. The sound absorption material 5, which may preferably be made of a particular strip-shaped cut wood softboard, here fills the gaps 4 completely.

Die Holzbautafeln 1, 2, 3 haben zumindest eine Trägerschicht 6, in der die zur Aufnahme von Schallabsorptionsmaterial 5 bestimmten Zwischenräume 4 vorgesehen sind. Die Holzbautafeln 1, 2, 3 tragen des weiteren eine in Gebrauchslage dem Raum zugewandte Sichtlage 7, die mit Öffnungen 8 versehen ist, welche sich bis zu den das Schallabsorptionsmaterial 5 aufweisenden Zwischenräumen 4 der Trägerschicht 6 erstrecken.The wood building panels 1, 2, 3 have at least one support layer 6, in which the intended for receiving sound absorption material 5 spaces 4 are provided. The timber boards 1, 2, 3 further carry a in the position of use facing the room viewing position 7, which is provided with openings 8, which extend up to the sound absorption material 5 having gaps 4 of the support layer 6.

Die Holzbautafeln 1, 2, 3 weisen auf der dem Raum zugewandten Sichtseite ihrer Sichtlage 7 eine stark strukturierte Oberfläche auf, die zur diffusen Streuung des reflektierenden Schalls bestimmt ist. Die Sichtlage 7 ist dazu sichtseitig gebürstet oder mit abrasiven Medien gestrahlt, derart, dass die Sichtlage 7 eine durch hervorstehende Jahresringe und durch demgegenüber zurückgesetzte Jahresring-Zwischenräume stark strukturierte Oberfläche hat.The wooden panels 1, 2, 3 have on the side facing the room of their sight layer 7 a highly structured surface, which is intended for diffuse scattering of the reflective sound. The visible layer 7 is visually brushed or blasted with abrasive media, such that the visual position 7 by a projecting annual rings and by contrast recessed annual ring spaces has a highly structured surface.

Durch die starke Oberflächenstruktur auf der Sichtseite der Holzbautafeln 1, 2, 3 wird nicht nur eine lebendige und ästhetisch ansprechende Optik begünstigt, - durch die stark strukturierte Oberfläche lässt sich vielmehr auch eine diffuse Streuung des reflektierten Schalls erreichen, wodurch die Sprachverständlichkeit und der musikalische Hörgenuss wesentlich verbessert werden kann, weil sich alle Frequenzen optimal im Raum verteilen.Due to the strong surface structure on the visible side of the wooden boards 1, 2, 3 not only a lively and aesthetically pleasing optics is favored, - by the highly structured surface can also achieve a diffuse scattering of the reflected sound, whereby the speech intelligibility and musical listening pleasure can be significantly improved because all frequencies are distributed optimally in the room.

Insbesondere aus den Fig. 1 bis 5, 10 und 12 wird deutlich, dass wenigstens eine größere Anzahl und vorzugsweise alle der in der Sichtlage 7 vorgesehenen Öffnungen 8 bis tief in das Schallabsorptionsmaterial 5 reichen, derart, dass diese Öffnungen 8 sich zumindest über die Hälfte der Dicke oder Längserstreckung des Schallabsorptionsmaterials 5 erstrecken.In particular from the Fig. 1 to 5 . 10 and 12 It will be appreciated that at least a greater number, and preferably all, of the apertures 8 provided in the face sheet 7 extend deep into the sound absorbing material 5 such that these apertures 8 extend at least halfway across the thickness or longitudinal extent of the sound absorbing material 5.

Diese derart tief in das Schallabsorptionsmaterial 5 reichenden Öffnungen 8 haben eine optische Tiefenwirkung, die das Erscheinungsbild der Holzbautafeln 1, 2, 3 wesentlich verbessert; entscheidend ist aber, dass diese tief in Schallabsorptionsmaterial 5 reichenden Öffnungen 8 sich auch durch eine verbesserte schallabsorbierende Wirkung auszeichnen. Durch diese vertiefte Ritzung der Sichtlage 7 können die in die Öffnungen 8 eindringenden Schallwellen auch seitlich beziehungsweise horizontal in das hinter der Sichtlage 7 befindliche Schallabsorptionsmaterial 5 der Trägerschicht 6 vorstoßen.These openings 8, which extend so deeply into the sound absorption material 5, have an optical depth effect which substantially improves the appearance of the wood building boards 1, 2, 3; but it is crucial that these deep 8 in sound absorbing material openings 8 are also characterized by an improved sound-absorbing effect. As a result of this recessed scratching of the visible layer 7, the sound waves penetrating into the openings 8 can also project laterally or horizontally into the sound absorption material 5 of the carrier layer 6 located behind the visible layer 7.

Dabei ergänzen sich die stark strukturierte Oberfläche der Sichtlage 7 einerseits und die tief in das Schallabsorptionsmaterial 5 reichenden Öffnungen 8 andererseits derart, dass eine besonders hohe Schallabsorption erreichbar ist, was insbesondere bei edlen und hochwertigen Sichtlagen 7 zu einer Materialersparnis und damit zu einer Kostenreduktion führen kann. Durch die erreichbaren hohen Schallabsorptionswerte können aber bei Bedarf auch Mengeneinsparungen bei der gesamten Absorberfläche oder bessere Absorptionswerte bei gleicher Fläche erzielt werden. Diese verbesserten Absorptionswerte sind auch mit dünneren beziehungsweise leichteren und entsprechend handlichen Holzbautafeln, beispielsweise im Holz-Innenausbau, erreichbar.In this case, the highly structured surface of the view layer 7 on the one hand and the deep 8 extending into the sound absorption material openings 8 on the other hand complement each other such that a particularly high sound absorption can be achieved, which in particular can lead to a saving of material and thus to a cost reduction with noble and high-quality sighting layers. Due to the achievable high sound absorption values, however, it is also possible, if required, to achieve quantity savings over the entire absorber surface or better absorption values for the same area. These improved absorption values can also be achieved with thinner or lighter and correspondingly handy wooden building panels, for example in wood interior construction.

Möglich ist auch, dass die Trägerschicht 6 mehrere, zumindest teilweise durch rostartig angeordnete Einzelelemente 9 gebildete, miteinander verbundene Einzelschichten aufweist. Mittels der Anzahl der Schichten kann die Gesamt-Dicke des Schallabsorptionsmaterials 5 variiert und somit das Absorptionsverhalten der Holzbautafeln 1, 2, 3 festgelegt werden. Das Schallabsorptionsmaterial 5 kann dabei jeweils zwischen den Einzelelementen klemmend gehalten sein, sodass separate Befestigungselemente für das Schallabsorptionsmaterial 5 oder eine Klebeverbindung nicht erforderlich sind und trotzdem ein sicherer Halt des Schallabsorptionsmaterials 5 an der Trägerschicht 6 sichergestellt ist.It is also possible that the carrier layer 6 has a plurality of individual layers formed at least partially by rust-like arranged individual elements 9. By means of the number of layers, the total thickness of the sound absorption material 5 can be varied and thus the absorption behavior of the wood building panels 1, 2, 3 can be determined. The sound absorption material 5 can be held in each case clamping between the individual elements, so that separate fasteners for the sound absorption material 5 or an adhesive connection are not required and still a secure hold of the sound absorption material 5 is secured to the support layer 6.

Es ist auch möglich, dass die Trägerschicht 6 der Holzbautafeln 1, 2, 3 zumindest aus einer ersten Schicht aus zueinander seitlich beabstandeten, parallel zueinander angeordneten Einzelelementen sowie einer zweiten Schicht aus kreuzweise zu der ersten Schicht angeordneten, zueinander seitlich beabstandeten Einzelelementen besteht, wobei die Zwischenräume zwischen den Einzelelementen zumindest einer der Schichten die Zwischenräume 4 für das Schallabsorptionsmaterial 5 bilden. Die Herstellung der Trägerschicht 6 ist dabei besonders einfach möglich, indem eine Anzahl von jeweils gleichartigen, lattenartigen Einzelelementen 9 zueinander ausgerichtet und die Einzelelemente 9 benachbarte Schichten an ihren Berührungspunkten miteinander verbunden, beispielsweise verleimt werden.It is also possible for the carrier layer 6 of the wooden building boards 1, 2, 3 to consist of at least one first layer of individual elements arranged laterally spaced apart from one another and a second layer of individual elements laterally spaced apart from one another Interspaces between the individual elements of at least one of the layers form the spaces 4 for the sound absorption material 5. The preparation of the carrier layer 6 is particularly easy possible by a number of similar, lath-like individual elements 9 aligned and the individual elements 9 adjacent layers connected to each other at their points of contact, for example, glued.

Die Sichtlage 7 kann bezüglich Material, Struktur und Farbgebung an individuelle Gestaltungswünsche angepasst werden. Hierzu ist es zweckmäßig, wenn die Sichtlage 7 eine Holzeinschichtplatte, eine Holzwerkstoffplatte oder dergleichen Platte ist, die vorzugsweise aus Weichholz und/oder Edelholz besteht.The visual position 7 can be adapted to individual design wishes in terms of material, structure and color. For this purpose, it is expedient if the visible layer 7 is a Holzzeilschichtplatte, a wood-based panel or the like plate, which preferably consists of softwood and / or exotic wood.

Es ist vorteilhaft, wenn die Verbindung zwischen der Trägerschicht 6 und der Sichtlage 7 eine Leimverbindung ist. Dadurch sind an der Außenseite der Sichtlage 7 keine Nägel oder dergleichen Verbindungselemente sichtbar, was ein harmonisches und hochwertiges Gesamterscheinungsbild der Holzbautafeln 1, 2, 3 bewirkt.It is advantageous if the connection between the carrier layer 6 and the visible layer 7 is a glue connection. As a result, no nails or the like connecting elements are visible on the outside of the visible layer 7, resulting in a harmonious and high-quality overall appearance of the timber boards 1, 2, 3.

Die zum Schallabsorptionsmaterial 5 vorstoßenden Öffnungen 8 sind hier als Schlitze ausgestaltet, wobei die Schlitzbreite, die Schlitzlänge und/oder der Abstand benachbarter Schlitze zueinander variabel sind. Das Einbringen der Öffnungen 8 ist dabei besonders einfach und schnell möglich, wenn die Öffnungen 8 durch Sägeschlitze gebildet sind, die nach dem Verbinden mit der Trägerschicht 6 in die Sichtlage 7 eingearbeitet werden. Die Schlitze müssen aber nicht Längsschlitze und insbesondere nicht die hier dargestellten parallelen Längsschlitze sein. Denkbar sind beispielsweise auch bogen-, kreis- oder spiralförmige Schlitze.The projecting to the sound absorbing material 5 openings 8 are designed here as slots, wherein the slot width, the slot length and / or the distance between adjacent slots are variable to each other. The introduction of the openings 8 is particularly simple and quickly possible if the openings 8 are formed by Sägeschlitze, which are incorporated after bonding with the carrier layer 6 in the face sheet 7. However, the slots need not be longitudinal slots and in particular not the parallel longitudinal slots shown here. Conceivable, for example, arcuate, circular or spiral slots.

Weitere, hier nicht dargestellte Ausführungsbeispiele sehen vor, dass die Öffnungen 8 als Bohrungen, Ausfräsungen oder dergleichen Ausnehmungen ausgestaltet sind, wobei die Dimensionierung der Ausnehmungen an der Sichtlage 7 variabel sind. Dabei lassen sich besonders individuell gestaltete Holzbautafeln 1, 2, 3 realisieren, beispielsweise mit kreisförmigen, rechteckigen oder dergleichen Ausnehmungen mit geometrischen Formgebungen. Denkbar sind auch Kombinationen unterschiedliche ausgebildeter Ausnehmungen.Further, not shown embodiments provide that the openings 8 are designed as holes, cutouts or the like recesses, the dimensions of the recesses are variable to the view layer 7. In this case, particularly individually designed wooden panels 1, 2, 3 can be realized, for example, with circular, rectangular or the like recesses with geometric shapes. Conceivable are combinations of different trained recesses.

Aus einem Vergleich der in den Fig. 1, 5, 7, 10 und 11 gezeigten Holzbautafel 1 und der in den Fig. 2, 4, 6, 8, 9 und 12 abgebildeten Holzbautafel 2 einerseits sowie der Holzbautafel 3 in Fig. 3 andererseits wird deutlich, dass die hier dargestellte Holzbautafel in verschiedenen Ausführungen mehrschichtig ausgestaltet sein kann. Während die in Fig. 3 dargestellte Holzbautafel nur aus der gestreiften, geritzten oder sonstwie mit Öffnungen 8 versehenen Sichtlage 7 sowie der die Zwischenräume 4 für das Schallabsorptionsmaterial 5 aufweisenden Trägerschicht 6 gebildet ist, sind die Holzbautafeln 1 und 2 mehrschichtig ausgestaltet und weisen auf ihre der Sichtlage 7 entgegengesetzten Seite eine Deckschicht 10 auf, mit der die Holzbautafeln 1, 2 der Wand oder Decke zugewandt sind. Während die Deckschicht 10 bei der Holzbautafel 2 aus dünnen, auf Abstand nebeneinander liegenden Brettlagen gebildet ist, ist die Deckschicht 10 bei der Holzbautafel 1 durch geschlossene beziehungsweise mit dünnen und ohne Abstand nebeneinander liegenden Brettlagen belegt. Die Deckschicht 10 der Holzbautafeln 1, 2 verbessert deren Stabilität und bildet bei der Holzbautafel 1 zusätzlich noch eine geschlossene rückseitige Oberfläche.From a comparison of the in the Fig. 1 . 5 . 7 . 10 and 11 shown Holzbautafel 1 and in the Fig. 2 . 4 . 6 . 8th . 9 and 12 illustrated wooden building board 2 on the one hand and the wooden building board 3 in Fig. 3 On the other hand, it is clear that the wooden wall panel shown here can be configured in several layers multilayered. While the in Fig. 3 illustrated timber board only from the striped, scribed or otherwise provided with openings 8 layer of vision 7 and the spaces 4 for the sound absorption material 5 having support layer 6 is formed, the wood panels 1 and 2 are configured multi-layered and have on their the viewing position 7 opposite side a cover layer 10, with the wooden panels 1, 2 facing the wall or ceiling. While the cover layer 10 is formed in the timber board 2 from thin, spaced apart adjacent board layers, the cover layer 10 is occupied in the timber board 1 by closed or with thin and without spacing adjacent board layers. The cover layer 10 of the timber panels 1, 2 improves their stability and forms in the timber panel 1 in addition to a closed back surface.
