Definitions
- the invention relates to an acoustic panel for producing a wall and ceiling covering according to the preamble of claim 1 and a wall and ceiling covering according to the preamble of claim 15.
- Acoustic panels are known both as single-layer and double-layer components. In this case, these mostly have a carrier plate with a visible side that is designed decoratively. An acoustic absorber is arranged on the rear side opposite the visible side. The visible side with the carrier plate has recesses through which sound waves occurring in a room penetrate and pass through the carrier plate into the absorber. Depending on the size of the recesses, the absorber is visible through the recesses. This is particularly troublesome when the color of the absorber does not match the color of the carrier plate or the visible side.
- Another known problem is that, precisely in the case of absorbers made of fibers, due to vibrations or shocks, fibers or even material parts become detached from the absorber and trickle through the recesses, for example on the floor of the room.
- This problem is well known in two-part systems, in which the absorber is first attached to the substrate and then the acoustic panel is mounted on the absorber.
- a known solution for this is the attachment of a fleece on the back of the acoustic panel, which is color-coordinated on the one hand with the front side and on the other hand with the flow properties of the absorber in order to prevent particles from the absorber from trickling through the recesses.
- the fleece brings various production difficulties with it. For example, if there are different basic colors on the front side, ie the visible side of the acoustic panel, different basic colors would also have to be used for the acoustic fleece.
- gluing difficulties often arise when gluing the fleece to the back of the acoustic panel. Subsequent operations are also much more difficult to carry out because the pressure stability of the fleece or the suction options during operations through the fleece are clearly restricted.
- the invention is based on the object of providing an acoustic panel and a wall and ceiling covering made of acoustic panels that prevent both the view from the front of the absorber and the trickling through of particles from the absorber through the acoustic panel.
- the invention solves the problem by means of an acoustic panel with the features of claim 1 and a wall and ceiling covering with the features of claim 15.
- Advantageous further developments of the invention are specified in the dependent claims. All of the features described, individually or in any combination, are fundamentally the subject matter of the invention, regardless of how they are summarized in the claims or their reference.
- the acoustic panel according to the invention for producing a wall and ceiling covering has a front side and a rear side with recesses extending into the acoustic panel from the front and the rear.
- at least one front-side and one rear-side recess are arranged offset from one another in sections and there is a through opening between the front-side and rear-side recesses.
- a core idea of the invention is that the recesses in the acoustic panel designed to receive the sound waves are designed in two parts. As described, a front-side recess is introduced into the acoustic panel starting from the front side. However, the recess does not completely penetrate the acoustic panel. A second rear recess is made from the rear and likewise does not penetrate completely through the acoustic panel, but only so far that a through opening is created between the front and rear recesses.
- the front-side recess is arranged offset to the rear-side recess in the acoustic panel.
- the recesses are formed offset from one another in the direction transverse to the panel plane (hereinafter referred to as the horizontal direction).
- the offset causes starting from the front to the offset and thus looking at the inside of the acoustic panel and not at the absorber, while the backside of the offset catches fibers or particles from the absorber that are loosening.
- the sound waves penetrating into the acoustic panel from the front can still penetrate the absorber through the passage opening.
- the recesses are arranged and designed in such a way that they extend in particular in the vertical direction, i.e. extend perpendicular to the panel plane in the acoustic panel.
- the vertical center axes of the front and rear recesses are thus arranged offset from one another in the horizontal direction.
- the vertical center axes of the recesses are not congruent.
- the acoustic panels usually have a carrier plate which is coated on the front with a decorative layer that forms the visible side.
- the decorative layer can, for example, be pressed on, like a synthetic resin laminate, as a lacquered decorative layer and / or as a laminated decorative layer.
- a possible rear-side coating is usually adapted accordingly to the front-side coating. The recesses thus protrude through the front and possibly the rear coating.
- the carrier boards can be wood-based panels, such as, for example, fiber boards, particle boards or OSB boards.
- the carrier plates can also comprise, for example, composite materials made of, in particular, cellulose-based particles, such as wood or paper, with a corresponding matrix material, such as plastic. Carrier plates that have plastic fibers can also be used.
- the carrier plates can in particular also contain fire-retardant agents in order to achieve the necessary fire protection requirements.
- the recesses extend, starting from the front side or from the rear side, in the vertical direction (perpendicular to the plane of the plate) in each case to the opposite side (front side or rear side) of the acoustic panel.
- the recesses are not completely offset from one another, but only in sections, which creates the through opening.
- a further development of the invention provides that the front and rear recesses extend in a direction perpendicular to the panel plane overlap and the through opening is arranged in particular in an overlapping portion of the recess.
- the actual depth of the respective recess base can be designed differently.
- the absolute depth of the front recess i.e. the distance from the front to the front-side recess base can be significantly smaller than the distance from the rear-side recess base to the rear side.
- the front-side recess protrudes deeper into the acoustic panel compared to the rear-side recess, which in particular significantly improves the overall view of the front side of the acoustic panel.
- a development of the invention provides that the ratio between the panel thickness and the depth of the front recess to the depth of the rear recess is between 10: 7: 6 to 13: 9: 5.
- the panel thickness relates to the entire thickness of the acoustic panel, ie including the front and possibly the rear coating. Accordingly, the depth from the front side, ie including the possible top-side coating, or the depth of the rear-side recess also the depth from the rear side, ie including the possible rear-side coating, must be considered for the depth of the front-side recess.
- the width of the recesses is also relevant for the acoustic effect. It has been found that, for a particularly good acoustic effect, the front-side recess to the rear-side recess has a width ratio of 2.5: 3.
- a particularly preferred embodiment of the acoustic panels provides that the recesses are designed as grooves that are in particular slit-shaped in the acoustic panel. Especially when it is designed as grooves, the preferred width ratio produces a particularly good sound effect.
- the grooves can be rectangular or square in cross section. They extend, for example, transversely to the longitudinal direction of the panel, but in particular in the direction of the longitudinal axis of the acoustic panel.
- An optically particularly preferred embodiment also provides that the front-side recesses are inserted, i.e.
- the front recesses in particular the grooves, do not extend over the entire panel length or panel width, but rather a panel section is present at the respective outer edges, which can be, for example, 2 to 5 cm wide, in which no recesses are arranged.
- the recesses on the underside extend over the entire length of the panel. If a continuous groove look is desired on the front, it is also possible to apply so-called decorative grooves, which optically extend the actual acoustic recesses to the respective outer edge of the acoustic panel, but only have a small depth, e.g. a depth in the range of 1 to 2 mm.
- the through openings can be designed individually.
- the through opening can also be a round or oval hole, possibly also as a right-angled opening.
- the through-opening extend over the entire length of the front-side recesses. This ensures that the sound waves penetrating into the recess from the front are for the most part completely passed through the acoustic panel and, for example, into an absorber.
- the cross-section of the recesses can be designed differently.
- the recess is designed to be semicircular, inclined or similar in the area of its recess base.
- the recesses each have a fold which is present in the area of their recess base. The fold is designed in particular as a 90 ° fold, whereby, on the one hand, the non-transparency from the front and, on the other hand, the non-trickling through of particles from the rear to the front can be ensured particularly well.
- the recesses on the underside are designed to open towards the rear side.
- the recesses on the underside are, for example, trapezoidal in cross-section (in particular an isosceles trapezoidal shape), the short parallel surface of the trapezoid forming the recess base. It has surprisingly been found that there is a particularly high acoustic effectiveness when the side surfaces (e.g.
- the diagonals of the trapezoid) of the recesses are arranged at an angle of 23 ° +/- 2 ° to the vertical axis of the acoustic panel.
- the rear recesses thus particularly advantageously have the shape of an isosceles trapezoid with the above-mentioned angles between the short parallels (recess base) and the two side surfaces (diagonals).
- the recess opening towards the rear enables a further preferred embodiment, according to which the plane formed by the through opening is inclined to the vertical axis. This significantly improves the possibility of passage for the sound waves from the front to the rear.
- the acoustic panels have locking profiles that correspond to one another and can be locked to one another without adhesive, in particular turn-swivel and / or push-button profiles, on at least two opposite side edges. Generate such locking profiles a joint and stepless connection between two acoustic panels that remains permanently. They ensure that, in the event of swelling and shrinking movements of individual acoustic panels or even of the entire panel surface, there is always a step-free connection between the individual acoustic panels.
- the locking profiles considerably simplify the installation of the acoustic panels compared to acoustic panels with classic tongue and groove profiles or acoustic panels without profiles.
- a profile plane is formed by the locking profiles. Starting from the front, this lies at the lowest point of the locking profile and extends parallel to the front and rear.
- the front recess is below the profile level of the acoustic panel protrudes.
- the above-mentioned locking profiles in particular the turn-swivel or push-button profiles, usually have a first profile with an upper groove cheek and a corresponding second locking profile with a lower groove cheek.
- the acoustic panels in particular in the wall area, are usually installed in such a way that the acoustic panels are installed with the upper groove cheek starting from the side edge.
- a further development of the invention provides that, in the case of two recesses forming a through opening, the distance between the rear recess and a side edge with the upper groove cheek is less than the distance between the front recess the side edge with the upper groove cheek.
- a further improvement in acoustic effectiveness is surprising achieved by a recess which is provided with a fold or two folds in the front area, which increases the width of the recess in the region of the fold.
- the front-side recess is 10% to 50% wider in the area up to a depth of 20% of its total depth compared to the recess width itself.
- a wall and ceiling covering comprising a multiplicity of acoustic panels of the aforementioned type, which are fastened to a subconstruction, a noise-reduced absorber being arranged adjacent to the rear side.
- the wall and ceiling covering advantageously has no further protective layer, for example a fleece layer between the rear side of the acoustic panel and an absorber.
- the absorber is thus arranged directly on the back of the acoustic panel.
- the view through, like the possible trickling through of particles from the absorber through the front and rear recesses, is successfully prevented by the offset arrangement of the front and rear recesses in the acoustic panel.
- the rear absorber can of course be connected to the rear side of the acoustic panel, for example glued, but in particular is not connected to the acoustic panel, but rather is designed as a separate component.
- the absorber is either attached directly to the substructure or, if necessary, also to a component (e.g. a wall or ceiling) to which the substructure is attached.
- a component e.g. a wall or ceiling
- the wall and ceiling covering can also be arranged on a partition wall formed by the substructure or on a freely suspended substructure and, for example, also form the partition wall or suspended ceiling.
- Figure 1 shows schematically in a perspective view an inventive acoustic panel 1 with a front side 2 and a rear side 3.
- the acoustic panel has a carrier plate 8 with a decorative laminate coating that forms the front side 2 and a backing (not shown here).
- the decorative coating and the back coating can also be lacquered, laminated or similarly applied to the surface.
- front-side recesses 4 are made in the acoustic panel 1.
- the recesses 4 are slit-shaped. They are made as slot-shaped grooves (see also Figure 2 ), ie that the front-side recesses 4 do not completely penetrate the acoustic panel 1 in the vertical direction V.
- the recesses are designed to be inserted, that is to say that they do not completely penetrate the acoustic panel even in the direction of the longitudinal axis, but that they are exposed in the end regions 5.
- decorative grooves 15 are worked into the surface in the end regions.
- a rear-side recess 6 is introduced into the acoustic panel 1, starting from the rear side 3.
- the front-side recess 4 and the rear-side recess 6 are via a through opening 7 (see Fig. Fig. 2 and 4th ) connected.
- the carrier plate 8 is made of wood material, here a fiber board. As already mentioned, the decorative coating on the top and the counter-coating on the back are not shown here.
- the embodiment from Figure 3 differs from the embodiment Figure 1 to the effect that the rear recesses 6 are trapezoidal in cross section.
- Fig. 2 and 4th the two embodiments are shown in cross section.
- the corresponding locking profiles 16, which are arranged on the side edges 10a, 10b of the acoustic panels 1 and can be locked without adhesive and which are in the Figures 1 and 3 not shown for the sake of simplicity.
- the locking profiles 16 have an upper groove cheek 14a on a first side edge 10a and a lower groove cheek 14b on the second side edge 10b opposite the first side edge and are designed here as turn-swivel profiles.
- the locking profiles 16 form a profile plane P.
- front-side recesses 4 protrude from the front side 2 to below the profile plane P.
- the rear recesses 6 end in the vertical direction V, on the other hand, starting from the rear 3 in front of the profile plane P.
- the front and rear recesses 4, 6 overlap in the vertical direction V.
- the central longitudinal axes M v of the front-side recesses 4, which are aligned in the vertical direction V, are offset in the direction transverse to the longitudinal axis direction Q of the acoustic panels 1 relative to the central longitudinal axes M R of the respective rear-side recess 6 connected via a through opening 7.
- the front-side recess 4 and rear-side recess 6, which are each connected via a through opening 7, are arranged offset to one another.
- the recesses 4, 6 connected via a through opening 7 are also arranged so as to overlap in the vertical direction V.
- Both the front-side recess 4 and the rear-side recess 6 thus each form a fold 13, which prevents the acoustic panel 1 from being seen through from a front side 2 and particles from trickling through from the rear side 3.
- the respective front-side recess 4 is closer to an upper groove cheek 14a of the locking profiles 16 than the respective rear-side recess 6.
- the rear recess 6 is closer to the upper groove cheek 14a than the associated front recess 4.
- the front recesses 4 shown and the rear recesses 6 are each shown as grooves with a rectangular cross section.
- the front recesses 4 are approximately 2.5 mm wide, while the rear recesses 6 are approximately 3 mm wide.
- the front-side recess 4 is also made widened in the surface area 9, that is to say here in the area of approximately up to 1 mm depth. This results in a significantly improved absorption of the sound waves in the front-side recess 4.
- FIG. 4 In contrast to the im Fig. 2 embodiment shown has the in Fig. 4
- the illustrated embodiment has rear recesses 6 with side surfaces 11, 11b arranged obliquely to the vertical direction.
- the side surfaces 11a, 11b are arranged here at an angle of 23 ° to the vertical V, so that the recess 6 on the underside opens towards the rear 3 (widened).
- the rear recess 6 is thus trapezoidal.
- the through openings 7 each form a plane aligned parallel to the vertical direction V, are those of the in Figures 3 and 4
- the illustrated embodiments formed planes of the through opening 7 are arranged at least in sections at an angle to the vertical V.
- the through opening 7 extends over the entire length of the front-side recess 4.
- a preferred embodiment (not shown) has a reverse arrangement, in which the rear recess 6 is arranged in the transverse direction Q closer to the upper groove cheek 14a than the associated front recess 4.

Description
Die Erfindung betrifft ein Akustikpaneel zum Herstellen eines Wand- und Deckenbelags gemäß dem Oberbegriff des Anspruchs 1 und einen Wand- und Deckenbelag gemäß dem Oberbegriff des Anspruchs 15.The invention relates to an acoustic panel for producing a wall and ceiling covering according to the preamble of claim 1 and a wall and ceiling covering according to the preamble of
Akustikpaneele sind sowohl als einlagige als auch zweilagige Bauelemente bekannt. Dabei weisen diese zumeist eine Trägerplatte mit einer Sichtseite auf, die dekorativ gestaltet ist. Auf der der Sichtseite gegenüberliegenden Rückseite ist ein akustischer Absorber angeordnet. Die Sichtseite mit der Trägerplatte weist Ausnehmungen auf, durch die in einem Raum auftretende Schallwellen eindringen und durch die Trägerplatte hindurch in den Absorber gelangen. Abhängig von der Größe der Ausnehmungen ist der Absorber durch die Ausnehmungen hindurch sichtbar. Dies ist insbesondere dann störend, wenn die Farbe des Absorbers nicht der Farbe der Trägerplatte bzw. der Sichtseite entspricht. Ein weiteres bekanntes Problem ist, dass gerade bei Absorbern aus Fasern aufgrund von Vibrationen oder Erschütterungen Fasern oder auch Stoffteile aus dem Absorber sich lösen und durch die Ausnehmungen hindurch bspw. auf dem Boden des Raums rieseln. Gerade bei zweiteiligen Systemen, bei denen der Absorber zuerst an dem Untergrund befestigt wird und anschließend das Akustikpaneel auf dem Absorber montiert wird, ist dieses Problem bekannt.Acoustic panels are known both as single-layer and double-layer components. In this case, these mostly have a carrier plate with a visible side that is designed decoratively. An acoustic absorber is arranged on the rear side opposite the visible side. The visible side with the carrier plate has recesses through which sound waves occurring in a room penetrate and pass through the carrier plate into the absorber. Depending on the size of the recesses, the absorber is visible through the recesses. This is particularly troublesome when the color of the absorber does not match the color of the carrier plate or the visible side. Another known problem is that, precisely in the case of absorbers made of fibers, due to vibrations or shocks, fibers or even material parts become detached from the absorber and trickle through the recesses, for example on the floor of the room. This problem is well known in two-part systems, in which the absorber is first attached to the substrate and then the acoustic panel is mounted on the absorber.
Eine hierfür bekannte Lösung ist das Anbringen eines Vlieses auf der Rückseite des Akustikpaneels, das zum einen farblich auf die Vorderseite abgestimmt ist und zum anderen auf die Rieseleigenschaften des Absorbers, um das Durchrieseln von Partikeln aus dem Absorber durch die Ausnehmungen zu verhindern. Das Vlies bringt jedoch verschiedene Produktionsschwierigkeiten mit sich. So müssten bspw. bei unterschiedlichen Grundfarben der Vorderseite, d.h. der Sichtseite des Akustikpaneels, auch unterschiedliche Grundfarben beim Akustikvlies benutz werden. Zudem treten häufig Verklebungsschwierigkeiten beim Verkleben des Vlieses mit der Rückseite des Akustikpaneels auf. Auch sind nachgelagerte Arbeitsgänge deutlich schwieriger durchzuführen, da die Druckstabilität des Vlieses oder auch die Absaugmöglichkeiten bei Arbeitsgängen durch das Vlies deutlich eingeschränkt sind.A known solution for this is the attachment of a fleece on the back of the acoustic panel, which is color-coordinated on the one hand with the front side and on the other hand with the flow properties of the absorber in order to prevent particles from the absorber from trickling through the recesses. However, the fleece brings various production difficulties with it. For example, if there are different basic colors on the front side, ie the visible side of the acoustic panel, different basic colors would also have to be used for the acoustic fleece. In addition, gluing difficulties often arise when gluing the fleece to the back of the acoustic panel. Subsequent operations are also much more difficult to carry out because the pressure stability of the fleece or the suction options during operations through the fleece are clearly restricted.
Der Erfindung liegt die Aufgabe zugrunde, ein Akustikpaneel und einen Wand- und Deckenbelag aus Akustikpaneelen bereit zu stellen, das sowohl die Durchsicht von der Vorderseite auf den Absorber als auch das Durchrieseln von Partikeln vom Absorber durch das Akustikpaneel verhindert.The invention is based on the object of providing an acoustic panel and a wall and ceiling covering made of acoustic panels that prevent both the view from the front of the absorber and the trickling through of particles from the absorber through the acoustic panel.
Die Erfindung löst die Aufgabe durch ein Akustikpaneel mit den Merkmalen des Anspruchs 1 und einen Wand- und Deckenbelag mit den Merkmalen des Anspruchs 15. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Dabei sind alle beschriebenen Merkmale für sich oder in beliebiger Kombination grundsätzlich Gegenstand der Erfindung, unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung.The invention solves the problem by means of an acoustic panel with the features of claim 1 and a wall and ceiling covering with the features of
Das erfinderische Akustikpaneel zum Herstellen eines Wand- und Deckenbelags weist eine Vorderseite und eine Rückseite mit sich von der Vorder- und von der Rückseite ausgehend in das Akustikpaneel erstreckenden Ausnehmungen auf. Dabei ist mindestens eine vorderseitige und eine rückseitige Ausnehmung abschnittsweise versetzt zueinander angeordnet und es liegt eine Durchgangsöffnung zwischen der vorderseitigen und rückseitigen Ausnehmung vor.The acoustic panel according to the invention for producing a wall and ceiling covering has a front side and a rear side with recesses extending into the acoustic panel from the front and the rear. In this case, at least one front-side and one rear-side recess are arranged offset from one another in sections and there is a through opening between the front-side and rear-side recesses.
Ein Kerngedanke der Erfindung ist, dass die zur Aufnahme der Schallwellen ausgebildeten Ausnehmungen im Akustikpaneel zweiteilig ausgebildet werden. Dabei wird, wie beschrieben, eine vorderseitige Ausnehmung ausgehend von der Vorderseite ins Akustikpaneel eingebracht. Die Ausnehmung durchdringt das Akustikpaneel jedoch nicht vollständig. Eine zweite rückseitige Ausnehmung wird von der Rückseite eingebracht und durchdringt das Akustikpaneel ebenfalls nicht vollständig, sondern nur so weit, dass zwischen der vorderseitigen und der rückseitigen Ausnehmung eine Durchgangsöffnung entsteht.A core idea of the invention is that the recesses in the acoustic panel designed to receive the sound waves are designed in two parts. As described, a front-side recess is introduced into the acoustic panel starting from the front side. However, the recess does not completely penetrate the acoustic panel. A second rear recess is made from the rear and likewise does not penetrate completely through the acoustic panel, but only so far that a through opening is created between the front and rear recesses.
Dabei ist die vorderseitige Ausnehmung zur rückseitigen Ausnehmung versetzt im Akustikpaneel angeordnet. D.h., dass die Ausnehmungen in Richtung quer zu der Paneelebene (im Weiteren Horizontalrichtung genannt) versetzt zueinander ausgebildet werden. Durch den Versatz wird bewirkt, dass ausgehend von der Vorderseite auf den Versatz und somit auf das Innere des Akustikpaneels und nicht auf den Absorber geguckt wird, während von der Rückseite der Versatz sich lösende Fasern oder Partikel aus dem Absorber auffängt. Die von der Vorderseite in das Akustikpaneel eindringenden Schallwellen können weiterhin durch die Durchgangsöffnung in den Absorber eindringen.The front-side recess is arranged offset to the rear-side recess in the acoustic panel. In other words, the recesses are formed offset from one another in the direction transverse to the panel plane (hereinafter referred to as the horizontal direction). The offset causes starting from the front to the offset and thus looking at the inside of the acoustic panel and not at the absorber, while the backside of the offset catches fibers or particles from the absorber that are loosening. The sound waves penetrating into the acoustic panel from the front can still penetrate the absorber through the passage opening.
Die Ausnehmungen werden dabei derart angeordnet und ausgebildet, dass sie sich insbesondere in Vertikalrichtung, d.h. senkrecht zur Paneelebene in das Akustikpaneel erstrecken.The recesses are arranged and designed in such a way that they extend in particular in the vertical direction, i.e. extend perpendicular to the panel plane in the acoustic panel.
Die vertikalen Mittelachsen der vorderseitigen und rückseitigen Ausnehmungen sind somit in Horizontalrichtung versetzt zueinander angeordnet. Eine Deckungsgleichheit der senkrechten Mittelachsen der Ausnehmungen liegt nicht vor.The vertical center axes of the front and rear recesses are thus arranged offset from one another in the horizontal direction. The vertical center axes of the recesses are not congruent.
Die Akustikpaneele weisen üblicherweise eine Trägerplatte auf, die vorderseitig mit einer Dekorschicht beschichtet ist, die die Sichtseite bildet. Dabei kann die Dekorschicht bspw. aufgepresst sein, wie ein Kunstharzlaminat, als auflackierte Dekorschicht und/oder als aufkaschierte Dekorschicht ausgebildet sein. Eine mögliche rückseitige Beschichtung ist üblicherweise an die vorderseitige Beschichtung entsprechend angepasst. Die Ausnehmungen ragen somit durch die vorderseitige und ggf. rückseitige Beschichtung durch.The acoustic panels usually have a carrier plate which is coated on the front with a decorative layer that forms the visible side. The decorative layer can, for example, be pressed on, like a synthetic resin laminate, as a lacquered decorative layer and / or as a laminated decorative layer. A possible rear-side coating is usually adapted accordingly to the front-side coating. The recesses thus protrude through the front and possibly the rear coating.
Die Trägerplatten können Holzwerkstoffplatten, wie bspw. als Faserplatten, Spanplatten oder OSB-Platten eingesetzt werden. Auch können die Trägerplatten bspw. Kompositwerkstoffe aus insbesondere zellulosebasierten Partikeln, wie bspw. Holz oder Papier mit einem entsprechenden Matrixmaterial, wie bspw. Kunststoff umfassen. Auch Trägerplatten, die Kunststofffasern aufweisen, sind verwendbar. Die Trägerplatten können insbesondere zudem brandhemmende Mittel enthalten, um entsprechende notwendige Brandschutzanforderungen zu erreichen.The carrier boards can be wood-based panels, such as, for example, fiber boards, particle boards or OSB boards. The carrier plates can also comprise, for example, composite materials made of, in particular, cellulose-based particles, such as wood or paper, with a corresponding matrix material, such as plastic. Carrier plates that have plastic fibers can also be used. The carrier plates can in particular also contain fire-retardant agents in order to achieve the necessary fire protection requirements.
Wie bereits ausgeführt, erstrecken sich die Ausnehmungen ausgehend von der Vorderseite bzw. von der Rückseite in Vertikalrichtung (senkrecht zur Plattenebene) jeweils zur gegenüberliegenden Seite (Vorderseite oder Rückseite) des Akustikpaneels. Dabei sind die Ausnehmungen nicht vollständig versetzt zueinander, sondern nur abschnittsweise, wodurch die Durchgangsöffnung entsteht.As already stated, the recesses extend, starting from the front side or from the rear side, in the vertical direction (perpendicular to the plane of the plate) in each case to the opposite side (front side or rear side) of the acoustic panel. The recesses are not completely offset from one another, but only in sections, which creates the through opening.
Insbesondere um die Größe der Durchgangsöffnung anzupassen und somit auch das Durchgangsmaß der Schallwellen von der vorderseitigen Ausnehmung durch die rückseitige Ausnehmung in einen möglichen Absorber zu steuern, ist nach einer Weiterbildung der Erfindung vorgesehen, dass die vorderseitige und die rückseitige Ausnehmung sich in Richtung senkrecht zur Paneelebene überlappen und die Durchgangsöffnung insbesondere in einem sich überlappenden Abschnitt der Ausnehmung angeordnet ist.In particular in order to adapt the size of the passage opening and thus also to control the degree of passage of the sound waves from the front recess through the rear recess into a possible absorber, a further development of the invention provides that the front and rear recesses extend in a direction perpendicular to the panel plane overlap and the through opening is arranged in particular in an overlapping portion of the recess.
D.h., dass neben dem Versatz in horizontaler Richtung (zumeist quer zur Paneellängsrichtung) auch ein Versatz (Überlappung) in Vertikalrichtung (zumeist in Richtung der Paneelstärke) der Ausnehmungen vorliegt. Der Abstand zwischen der Vorderseite und einem Ausnehmungsgrund der vorderseitigen Ausnehmung (tiefster Punkt der Ausnehmung im Akustikpaneel) ist somit in jedem Fall größer als der Abstand des Ausnehmungsgrundes der rückseitigen Ausnehmung zur Vorderseite.This means that in addition to the offset in the horizontal direction (mostly transverse to the longitudinal direction of the panel) there is also an offset (overlap) in the vertical direction (mostly in the direction of the panel thickness) of the recesses. The distance between the front and a recess base of the front recess (lowest point of the recess in the acoustic panel) is thus in any case greater than the distance between the recess base of the rear recess and the front.
Die eigentliche Tiefe des jeweiligen Ausnehmungsgrundes kann dabei unterschiedlich gestaltet werden. So kann bspw. die absolute Tiefe der vorderseitigen Ausnehmung, d.h. der Abstand von der Vorderseite zum vorderseitigen Ausnehmungsgrund deutlich geringer sein, als der Abstand des rückseitigen Ausnehmungsgrundes zur Rückseite. Nach einer Weiterbildung der Erfindung ist jedoch vorgesehen, dass bei zwei eine Durchgangsöffnung ausbildenden Ausnehmungen die vorderseitige Ausnehmung tiefer ins Akustikpaneel ragt gegenüber der rückseitigen Ausnehmung, wodurch insbesondere die Gesamtansicht der Vorderseite des Akustikpaneels deutlich verbessert wird.The actual depth of the respective recess base can be designed differently. For example, the absolute depth of the front recess, i.e. the distance from the front to the front-side recess base can be significantly smaller than the distance from the rear-side recess base to the rear side. According to a further development of the invention, however, it is provided that with two recesses forming a through opening, the front-side recess protrudes deeper into the acoustic panel compared to the rear-side recess, which in particular significantly improves the overall view of the front side of the acoustic panel.
Um insbesondere für die optische Wirkung, d.h. für die Ansicht des Akustikpaneels, eine optimale Wirkung zu erzielen ist nach einer Weiterbildung der Erfindung vorgesehen, dass das Verhältnis zwischen der Paneelstärke zur Tiefe der vorderseitigen Ausnehmung zur Tiefe der rückseitigen Ausnehmung zwischen 10:7:6 bis 13:9:5 beträgt.In order in particular for the visual effect, i. For the view of the acoustic panel to achieve an optimal effect, a development of the invention provides that the ratio between the panel thickness and the depth of the front recess to the depth of the rear recess is between 10: 7: 6 to 13: 9: 5.
Die Paneelstärke betrifft dabei die gesamte Stärke des Akustikpaneels, d.h. inklusive der vorderseitigen und ggf. rückseitigen Beschichtung. Dementsprechend ist bei der Tiefe der vorderseitigen Ausnehmung auch die Tiefe von der Vorderseite, d.h. inklusive der möglichen oberseitigen Beschichtung bzw. bei der Tiefe der rückseitigen Ausnehmung auch die Tiefe von der Rückseite, d.h. inklusive der möglichen rückseitigen Beschichtung, zu betrachten.The panel thickness relates to the entire thickness of the acoustic panel, ie including the front and possibly the rear coating. Accordingly, the depth from the front side, ie including the possible top-side coating, or the depth of the rear-side recess also the depth from the rear side, ie including the possible rear-side coating, must be considered for the depth of the front-side recess.
Neben der Tiefe der Ausnehmungen ist auch die Breite der Ausnehmungen für die akustische Wirkung relevant. So hat sich herausgestellt, dass für eine besonders gute akustische Wirkung die vorderseitige Ausnehmung zu der rückseitigen Ausnehmung ein Breitenverhältnis von 2,5:3 aufweist.In addition to the depth of the recesses, the width of the recesses is also relevant for the acoustic effect. It has been found that, for a particularly good acoustic effect, the front-side recess to the rear-side recess has a width ratio of 2.5: 3.
Eine besonders bevorzugte Ausführungsform der Akustikpaneele sieht vor, dass die Ausnehmungen als Nuten ausgebildet sind, die insbesondere Schlitzförmig im Akustikpaneel vorliegen. Gerade bei einer Ausbildung als Nuten bewirkt das bevorzugte Breitenverhältnis eine besonders gute Schallwirkung. Die Nuten können im Querschnitt rechtwinklig oder quadratisch ausgebildet sein. Sie erstrecken sich bspw. quer zur Paneellängsrichtung, insbesondere jedoch in Längsachsenrichtung des Akustikpaneels. Eine optisch besonders bevorzugte Ausführungsform sieht zudem vor, dass die vorderseitigen Ausnehmungen eingesetzt sind, d.h. dass die vorderseitigen Ausnehmungen, insbesondere die Nuten, sich nicht über die gesamte Paneellänge oder Paneelbreite erstrecken, sondern an den jeweiligen Außenkanten ein Paneelabschnitt vorliegt, der bspw. 2 bis 5 cm breit sein kann, in dem keine Ausnehmungen angeordnet sind. Um die akustische Wirkung bei einer derartigen vorderseitigen Ausgestaltung weiter zu verbessern, ist zudem vorzugsweise vorgesehen, dass die unterseitigen Ausnehmungen sich über die gesamte Paneellänge erstrecken. Sollte vorderseitig eine durchgängige Nutoptik gewünscht sein, ist es zudem möglich sogenannte Ziernuten anzubringen, die die eigentlichen akustischen Ausnehmungen bis zur jeweiligen Außenkante des Akustikpaneels optisch verlängern, jedoch nur eine geringe Tiefe, bspw. eine Tiefe im Bereich von 1 bis 2 mm aufweisen.A particularly preferred embodiment of the acoustic panels provides that the recesses are designed as grooves that are in particular slit-shaped in the acoustic panel. Especially when it is designed as grooves, the preferred width ratio produces a particularly good sound effect. The grooves can be rectangular or square in cross section. They extend, for example, transversely to the longitudinal direction of the panel, but in particular in the direction of the longitudinal axis of the acoustic panel. An optically particularly preferred embodiment also provides that the front-side recesses are inserted, i.e. that the front recesses, in particular the grooves, do not extend over the entire panel length or panel width, but rather a panel section is present at the respective outer edges, which can be, for example, 2 to 5 cm wide, in which no recesses are arranged. In order to further improve the acoustic effect in such a front-side configuration, it is also preferably provided that the recesses on the underside extend over the entire length of the panel. If a continuous groove look is desired on the front, it is also possible to apply so-called decorative grooves, which optically extend the actual acoustic recesses to the respective outer edge of the acoustic panel, but only have a small depth, e.g. a depth in the range of 1 to 2 mm.
Grundsätzlich sind die Durchgangsöffnungen individuell gestaltbar. So kann gerade bei der Ausgestaltung der Ausnehmung bspw. als Löcher auch die Durchgangsöffnung entsprechend als rundes oder ovales Loch, ggf. auch als rechtwinklige Öffnungen vorliegen. Besonders bevorzugt wird jedoch, dass die Durchgangsöffnung sich über die gesamte Länge der vorderseitigen Ausnehmungen erstrecken. Hierdurch ist gewährleistet, dass die von der Vorderseite in die Ausnehmung eindringenden Schallwellen weitestgehend vollständig durch das Akustikpaneel hindurch und bspw. bis in einen Absorber geleitet werden.Basically, the through openings can be designed individually. For example, when the recess is designed, for example, as a hole, the through opening can also be a round or oval hole, possibly also as a right-angled opening. However, it is particularly preferred that the through-opening extend over the entire length of the front-side recesses. This ensures that the sound waves penetrating into the recess from the front are for the most part completely passed through the acoustic panel and, for example, into an absorber.
Grundsätzlich kann der Querschnitt der Ausnehmungen unterschiedlich ausgebildet werden. So ist es bspw. denkbar, dass die Ausnehmung im Bereich ihres Ausnehmungsgrundes halbrund, schräg oder ähnlich ausgebildet sind. Besonders bevorzugt weisen die Ausnehmungen jedoch jeweils einen Falz auf, der im Bereich ihres Ausnehmungsgrundes vorliegt. Dabei ist der Falz insbesondere als 90°-Falz ausgebildet, wodurch zum einen die Nichtdurchsichtbarkeit von der Vorderseite und zum anderen auch die Nichtdurchrieselbarkeit von Partikeln von der Rückseite zur Vorderseite besonders gut gewährleistet werden kann.In principle, the cross-section of the recesses can be designed differently. For example, it is conceivable that the recess is designed to be semicircular, inclined or similar in the area of its recess base. However, it is particularly preferred that the recesses each have a fold which is present in the area of their recess base. The fold is designed in particular as a 90 ° fold, whereby, on the one hand, the non-transparency from the front and, on the other hand, the non-trickling through of particles from the rear to the front can be ensured particularly well.
Um sowohl die akustische Wirkung des Akustikpaneels zu verbessern als auch die Durchrieselbarkeit von Partikeln von der Rückseite in Richtung der Vorderseite weiter zu minimieren, ist nach einer Weiterbildung der Erfindung vorgesehen, dass die unterseitigen Ausnehmungen sich zur Rückseite öffnend ausgebildet sind. D.h., dass die unterseitigen Ausnehmungen von der Rückseite ausgehend bspw. im Querschnitt trapezförmig (insbesondere eine gleichschenklige Trapezform) sind, wobei die kurze parallele Fläche des Trapezes den Ausnehmungsgrund bildet. Dabei hat sich überraschenderweise herausgestellt, dass eine besonders hohe akustische Wirksamkeit vorliegt, wenn die Seitenflächen (bspw. die Diagonalen des Trapezes) der Ausnehmungen in einem Winkel von 23° +/- 2° zur Vertikalachse des Akustikpaneels angeordnet sind. Besonders vorteilhaft weisen die rückseitigen Ausnehmungen somit die Form eines gleichschenkeligen Trapezes mit den oben genannten Winkeln zwischen der kurzen Parallelen (Ausnehmungsgrund) und den beiden Seitenflächen (Diagonalen) auf.In order to both improve the acoustic effect of the acoustic panel and further minimize the ability of particles to trickle through from the rear side in the direction of the front side, a further development of the invention provides that the recesses on the underside are designed to open towards the rear side. This means that, starting from the rear, the recesses on the underside are, for example, trapezoidal in cross-section (in particular an isosceles trapezoidal shape), the short parallel surface of the trapezoid forming the recess base. It has surprisingly been found that there is a particularly high acoustic effectiveness when the side surfaces (e.g. the diagonals of the trapezoid) of the recesses are arranged at an angle of 23 ° +/- 2 ° to the vertical axis of the acoustic panel. The rear recesses thus particularly advantageously have the shape of an isosceles trapezoid with the above-mentioned angles between the short parallels (recess base) and the two side surfaces (diagonals).
Die sich zur Rückseite öffnende Ausnehmung ermöglicht eine weitere bevorzugte Ausführungsform, nach der die durch die Durchgangsöffnung gebildete Ebene schräg zur Vertikalachse steht. Hierdurch wird die Durchgangsmöglichkeit für die Schallwellen von der Vorderseite zur Rückseite deutlich verbessert.The recess opening towards the rear enables a further preferred embodiment, according to which the plane formed by the through opening is inclined to the vertical axis. This significantly improves the possibility of passage for the sound waves from the front to the rear.
Die Verbindungsmöglichkeit der Akustikpaneele untereinander kann unterschiedlich ausgebildet sein. So können diese bspw. stumpf aneinander stoßen. Auch sind klassische Nut-Feder-Verbindungen denkbar. Besonders bevorzugt weisen die Akustikpaneele jedoch an mindestens zwei gegenüberliegenden Seitenkanten zueinander korrespondierende, klebemittellos aneinander verriegelbare Verriegelungsprofile, insbesondere Dreh-Schwenk- und/oder Druckknopf-Profile auf. Derartige Verriegelungsprofile erzeugen eine fugen- und absatzlose Verbindung zwischen zwei Akustikpaneelen, die dauerhaft bestehen bleibt. Sie gewährleisten, dass bei Quell- und Schwindbewegungen einzelner Akustikpaneele oder auch der gesamten Paneelfläche immer eine absatz- und fugenlose Verbindung zwischen den einzelnen Akustikpaneelen vorliegt. Die Verriegelungsprofile vereinfachen die Montage der Akustikpaneele gegenüber Akustikpaneelen mit klassischen Nut-Feder-Profilen oder auch profillosen Akustikpaneelen erheblich.The possibility of connecting the acoustic panels to one another can be designed differently. For example, these can butt against each other. Classic tongue and groove connections are also conceivable. Particularly preferably, however, the acoustic panels have locking profiles that correspond to one another and can be locked to one another without adhesive, in particular turn-swivel and / or push-button profiles, on at least two opposite side edges. Generate such locking profiles a joint and stepless connection between two acoustic panels that remains permanently. They ensure that, in the event of swelling and shrinking movements of individual acoustic panels or even of the entire panel surface, there is always a step-free connection between the individual acoustic panels. The locking profiles considerably simplify the installation of the acoustic panels compared to acoustic panels with classic tongue and groove profiles or acoustic panels without profiles.
Durch die Verriegelungsprofile wird eine Profilebene ausgebildet. Diese liegt ausgehend von der Vorderseite am tiefsten Punkt der Verriegelungsprofile und erstreckt sich parallel zur Vorder- und Rückseite. Um eine optimale akustische Wirkung zu erzeugen und zudem auch noch die Durchsichtbarkeit durch die Ausnehmungen bestmöglich zu verhindern bzw. das Durchrieseln von Partikeln von der Rückseite zur Vorderseite zu blockieren ist nach einer Weiterbildung der Erfindung vorgesehen, dass die vorderseitige Ausnehmung bis unter die Profilebene des Akustikpaneels ragt.A profile plane is formed by the locking profiles. Starting from the front, this lies at the lowest point of the locking profile and extends parallel to the front and rear. In order to create an optimal acoustic effect and also to prevent visibility through the recesses as well as possible or to block the trickling through of particles from the back to the front, a further development of the invention provides that the front recess is below the profile level of the acoustic panel protrudes.
Die oben genannten Verriegelungsprofile, insbesondere die Dreh-Schwenk- oder Druccknopf-Profile, weisen üblicherweise ein erstes Profil mit einer oberen Nutwange und ein dazu korrespondierendes zweites Verriegelungsprofil mit einer unteren Nutwange auf. Die Montage der Akustikpaneele, insbesondere im Wandbereich, erfolgt üblicherweise derart, dass die Akustikpaneele ausgehend von der Seitenkante mit der oberen Nutwange montiert werden.The above-mentioned locking profiles, in particular the turn-swivel or push-button profiles, usually have a first profile with an upper groove cheek and a corresponding second locking profile with a lower groove cheek. The acoustic panels, in particular in the wall area, are usually installed in such a way that the acoustic panels are installed with the upper groove cheek starting from the side edge.
Um das Durchrieseln von Partikeln ausgehend von der Rückseite zur Vorderseite noch umfassender zu verhindern ist nach einer Weiterbildung der Erfindung vorgesehen, dass bei zwei eine Durchgangsöffnung ausbildenden Ausnehmungen der Abstand der rückseitigen Ausnehmung zu einer Seitenkante mit oberer Nutwange geringer ist gegenüber dem Abstand der vorderseitigen Ausnehmung zu der Seitenkante mit der oberen Nutwange. Hierdurch werden gerade bei Wandpaneelen Partikel, die sich von einem rückseitig angeordneten Absorber lösen, in der rückseitigen Ausnehmung aufgefangen. Der durch den Versatz vorliegende Absatz zwischen der vorderseitigen und rückseitigen Ausnehmung verhindert besonders wirkungsvoll, dass diese Partikel aufgrund von Vibrationen oder Ähnlichem zur Vorderseite durchrieseln.In order to prevent particles from trickling through from the back to the front even more comprehensively, a further development of the invention provides that, in the case of two recesses forming a through opening, the distance between the rear recess and a side edge with the upper groove cheek is less than the distance between the front recess the side edge with the upper groove cheek. As a result, especially in the case of wall panels, particles that detach from an absorber arranged on the rear are caught in the rear recess. The shoulder between the front and rear recesses caused by the offset is particularly effective in preventing these particles from trickling through to the front due to vibrations or the like.
Eine weitere Verbesserung der akustischen Wirksamkeit wird überraschenderweise durch eine Ausnehmung erreicht, die im vorderseitigen Bereich mit einem Falz bzw. zwei Falzen versehen ist, der die Breite der Ausnehmung im Bereich des Falzes vergrößert. So ist nach einer Weiterbildung der Erfindung vorgesehen, dass die vorderseitige Ausnehmung im Bereich bis zu einer Tiefe von 20% ihrer Gesamttiefe um 10% bis 50% breiter gegenüber der Ausnehmungsbreite an sich ist.A further improvement in acoustic effectiveness is surprising achieved by a recess which is provided with a fold or two folds in the front area, which increases the width of the recess in the region of the fold. Thus, according to a further development of the invention, it is provided that the front-side recess is 10% to 50% wider in the area up to a depth of 20% of its total depth compared to the recess width itself.
Weiter wird die Aufgabe gelöst durch einen Wand- und Deckenbelag, umfassend eine Vielzahl von Akustikpaneelen der vorgenannten Art, die an einer Unterkonstriktion befestigt sind, wobei an die Rückseite angrenzend ein schallreduzierter Absorber angeordnet ist.The object is also achieved by a wall and ceiling covering, comprising a multiplicity of acoustic panels of the aforementioned type, which are fastened to a subconstruction, a noise-reduced absorber being arranged adjacent to the rear side.
Der Wand- und Deckenbelag weist in vorteilhafter Weise keine weitere Schutzschicht, bspw. eine Vliesschicht zwischen der Rückseite des Akustikpaneels und einem Absorber auf. Der Absorber ist somit direkt an der Rückseite des Akustikpaneels angeordnet. Die Durchsicht wird genauso wie das mögliche Durchrieseln von Partikeln ausgehend vom Absorber durch die vorder- und rückseitigen Ausnehmungen durch die versetzte Anordnung der vorderseitigen und rückseitigen Ausnehmungen im Akustikpaneel erfolgreich verhindert.The wall and ceiling covering advantageously has no further protective layer, for example a fleece layer between the rear side of the acoustic panel and an absorber. The absorber is thus arranged directly on the back of the acoustic panel. The view through, like the possible trickling through of particles from the absorber through the front and rear recesses, is successfully prevented by the offset arrangement of the front and rear recesses in the acoustic panel.
Der rückseitige Absorber kann selbstverständlich mit der Rückseite des Akustikpaneels verbunden, bspw. verklebt sein, ist insbesondere jedoch mit dem Akustikpaneel nicht verbunden, sondern als separates Bauteil ausgebildet. Der Absorber wird entweder direkt an der Unterkonstruktion oder ggf. auch an einem Bauteil (bspw. einer Wand oder Decke), an der die Unterkonstruktion befestigt ist, befestigt. Selbstverständlich kann der Wand- und Deckenbelag auch an einer durch die Unterkonstruktion gebildeten Zwischenwand oder einer freihängenden Unterkonstruktion angeordnet sein und bspw. die Zwischenwand oder abgehängte Decke mit ausbilden.The rear absorber can of course be connected to the rear side of the acoustic panel, for example glued, but in particular is not connected to the acoustic panel, but rather is designed as a separate component. The absorber is either attached directly to the substructure or, if necessary, also to a component (e.g. a wall or ceiling) to which the substructure is attached. Of course, the wall and ceiling covering can also be arranged on a partition wall formed by the substructure or on a freely suspended substructure and, for example, also form the partition wall or suspended ceiling.
