Wand- oder DeckenverkleidungWall or ceiling paneling

Die Erfindung betrifft eine schallabsorbierende Wand- oder Deckenverkleidung, die bei geringem Gewicht eine hohe Stabilität aufwiest.The invention relates to a sound-absorbing wall or ceiling panelling which is highly stable despite its low weight.

Dies wird erfindungsgemäß dadurch erreicht, dass auf einem Metallblech ein Holzfurnier oder ein Laminat aufgeklebt ist, und der so ausgebildete Verbund mit einer Lochung versehen wird, um eine Schallabsorption zu erreichen. Durch die Verwendung eines dünnen Metallblechs wird eine hohe Stabilität erreicht, wobei die Verbundplatte insgesamt ein geringes Gewicht pro Flächeneinheit gegenüber einer Holzplatte hat. Bei Verwendung eines Holzfurniers als Beschichtung des Metallblechs kann eine Wand- oder Deckenverkleidung mit Holzcharakter ausgebildet werden, die einen nicht brennbaren Aufbau nach der Baustoffklasse A2 nach DIN 4102 ergibt.This is achieved according to the invention by gluing a wood veneer or laminate onto a metal sheet and perforating the composite thus formed to achieve sound absorption. By using a thin metal sheet, a high level of stability is achieved, with the composite panel having a lower weight per unit area than a wood panel. By using a wood veneer as a coating for the metal sheet, a wall or ceiling paneling with a wood character can be formed, which results in a non-combustible structure in accordance with building material class A2 according to DIN 4102.

Die Erfindung wird beispielsweise anhand der Zeichnung näher erläutert, die schematisch Querschnittsansichten einer Verbundplatte nach der Erfindung zeigt.The invention is explained in more detail with reference to the drawing, for example, which shows schematic cross-sectional views of a composite panel according to the invention.

Zu Fig. 1 ist ein Metallblech aus Aluminium oder Stahl bezeichnet, dessen Ränder zur Ausbildung eines Decken- oder Wandpaneels aufgebogen sein können, wie dies bei herkömmlichen Deckenverkleidungen bekannt ist. Auf der Sichtseite ist ein Holzfurnier 2 aufgeklebt und die so ausgebildete Verbundplatte ist mit einer durchgehenden Lochung 3 versehen.Fig. 1 shows a metal sheet made of aluminum or steel, the edges of which can be bent up to form a ceiling or wall panel, as is known in conventional ceiling cladding. A wood veneer 2 is glued to the visible side and the composite panel thus formed is provided with a continuous perforation 3.

Das Metallblech 1 kann eine Dicke von vorzugsweise 0,5 bis 3 mm haben. Das Holzfurnier 2 kann 0,5 bis 4 mm dick sein, wobei die Sichtseite der Furnierbeschichtung gebeizt, lasiert oder lackiert sein kann. Das Holzfurnier kann beispielsweise ein Messer-, Schäl- oder Sägefurnier sein.The metal sheet 1 can have a thickness of preferably 0.5 to 3 mm. The wood veneer 2 can be 0.5 to 4 mm thick, whereby the visible side of the veneer coating can be stained, glazed or painted. The wood veneer can be, for example, a sliced, rotary-cut or sawn veneer.

Die zur Erzielung einer Schallabsorption vorgesehene Lochung 3 kann in verschiedener Weise ausgebildet sein. Vorzugsweise wird eine freie Querschnittsfläche der Lochung von 0,5 bis 30 % vorgesehen. Der Lochdurchmesser kann 0,5 bis 30 mm betragen, vorzugsweise 0,5 bisThe perforation 3 intended to achieve sound absorption can be designed in various ways. Preferably, a free cross-sectional area of the perforation of 0.5 to 30% is provided. The hole diameter can be 0.5 to 30 mm, preferably 0.5 to

5,0 mm. Die Form der Lochung kann unterschiedlich sein. Beispielsweise können anstelle von kreisförmigen Lochungen auch geschlitzte, quadratische, rautenförmige oder andere Umrissformen der Lochung vorgesehen werden.5.0 mm. The shape of the holes can vary. For example, instead of circular holes, slotted, square, diamond-shaped or other outline shapes of holes can be provided.

Anstelle von Echtholzfurnier kann auch eine Schichtstoffplatte aus Kunststoff als Beschichtung 2 auf das Metallblech 1 aufgeklebt werden, wobei die Sichtseite der Schichtstoffplatte dadurch einen Holzcharakter erhalten kann, dass man für den Aufbau der Schichtstoffplatte ein mit Phenolharz getränktes Papier mit der Abbildung eines Holzfurniers verwendet, das mit der Schichtstoffplatte verpresst ist. Das Laminat kann auch mit einem Dekorpapier versehen sein. Die Dicke der Laminatbeschichtung 2 kann beispielsweise bei 0,5 bis 1,0 mm liegen.Instead of real wood veneer, a plastic laminate can also be glued to the metal sheet 1 as a coating 2, whereby the visible side of the laminate can be given a wood character by using a paper soaked in phenolic resin with an image of a wood veneer, which is pressed onto the laminate. The laminate can also be provided with a decorative paper. The thickness of the laminate coating 2 can be, for example, 0.5 to 1.0 mm.

Da bei Verwendung eines dünnen Metallblechs und eines Echtholzfurniers durch das Ausdehnungsverhalten des Holzfurniers eine Spannung auf der Sichtseite der Verbundplatte entstehen kann, kann auf der Rückseite des Metallblechs 1 eine entsprechende Beschichtung 4, beispielsweise ebenfalls ein Holzfurnier, aufgebracht werden, das einen entsprechenden Gegenzug zu der Beschichtung 2 auf der Sichtseite erzeugt. Hierfür kann auch ein Vlies oder Papier verwendet werden.Since the use of a thin metal sheet and a real wood veneer can result in tension on the visible side of the composite panel due to the expansion behavior of the wood veneer, a corresponding coating 4, for example also a wood veneer, can be applied to the back of the metal sheet 1, which creates a corresponding counter-tension to the coating 2 on the visible side. A fleece or paper can also be used for this.

Die Beschichtung 4 auf der Rückseite des Metallblechs 1 kann auch durchgehend, d. h. ohne Lochung ausgebildet sein, wie dies Fig. 2 beispielsweise zeigt.The coating 4 on the back of the metal sheet 1 can also be continuous, i.e. without perforations, as shown in Fig. 2, for example.

Das beschriebene Verkleidungselement kann auf der Rückseite mit Vlies, Mineralwolle oder anderen Schallabsorptionsmaterialien belegt, beklebt oder hinterlegt sein, wie dies bei herkömmlichen schallabsorbierenden Deckenelementen bekannt ist.The described cladding element can be covered, glued or backed on the back with fleece, mineral wool or other sound absorption materials, as is known with conventional sound-absorbing ceiling elements.

Eine Verbundplatte der beschriebenen Art wird insbesondere im Innenausbau für Trennwände und abgehängte Decken verwendet.A composite panel of the type described is used particularly in interior construction for partition walls and suspended ceilings.

Dadurch, dass ein Metallblech für die Verbundplatte verwendet wird, kann diese auch an vorgegebene Formen angepasst werden, beispielsweise indem die Verbundplatte auf eine vorgegebene Wölbung einer Wand oder eines Wandteils aufgebracht und mit dieser kraftschlüssig verbunden wird, so dass die Verbundplatte die Form des Wandteils annimmt und beibehält.Because a metal sheet is used for the composite panel, it can also be adapted to given shapes, for example by applying the composite panel to a given curvature of a wall or part of a wall and connecting it to it in a force-fitting manner so that the composite panel takes on and retains the shape of the part of the wall.

Nach einer anderen Ausgestaltung kann die Verbundplatte mit einem vorgegebenen Muster geprägt werden. Nach einer anderen Ausgestaltung kann die Verbundplatte nach Art eines Wellblechs geformt sein. Je nach Art der verwendeten Furnierbeschichtung, beispielsweise nach Art von Holzriemen, kann die Formgebung des Metallblechs bzw. der Verbundplatte der durch das Furnier vorgegebenen Form angepasst werden.According to another embodiment, the composite panel can be embossed with a predetermined pattern. According to another embodiment, the composite panel can be shaped like a corrugated sheet. Depending on the type of veneer coating used, for example like a wooden strip, the shape of the metal sheet or composite panel can be adapted to the shape given by the veneer.

Nach einer weiteren Abwandlung kann auf der Sichtseite eine durchgehende, die Lochung abdeckende Beschichtung vorgesehen werden, beispielsweise eine weitgehend transparente, mikroporöse Folie.According to a further modification, a continuous coating covering the perforation can be provided on the visible side, for example a largely transparent, microporous film.

Insgesamt ergibt sich durch die Verwendung eines beschichteten Metallblechs eine leichte, aber sehr stabile Verbundplatte für Wand- oder Deckenverkleidungen, wobei sich durch die Möglichkeit der Formgebung der Verbundplatte vielfältige Einsatzmöglichkeiten ergeben.Overall, the use of a coated metal sheet results in a light but very stable composite panel for wall or ceiling cladding, with the possibility of shaping the composite panel opening up a wide range of possible applications.
