Abstract

The invention relates to a light building board comprising a honeycomb core (1) and planking (4) on at least two sides. Said light building board is provided with improved sound-absorbing properties. One or both sides of the planking (4) encompass/es breakthroughs (5). The planking (4) can be formed by a sheet of veneer, a decorative film, or a decorative paper. According to figure 2, the honeycomb core (1) is made of paper. The planking (4) is reinforced with the aid of wooden plates (3). An acoustic fleece (2) is disposed between the paper honeycomb core (1) and the wooden plates (4).

Description

Leichtbauplatte mit einem WabenkernLightweight panel with a honeycomb core
Die Erfindung betrifft eine Leichtbauplatte mit einem Wabenkern und mindestens zweiseitiger Beplankung.The invention relates to a lightweight board with a honeycomb core and at least two-sided planking.
Wand- oder Deckenverkleidungen sowie Möbelelemente mit schallabsorbierenden Eigenschaften werden in vielfacher Weise hergestellt. Üblicherweise bestehen die Verkleidungsplatten aus Holzwerkstoffen, deren Oberfläche durch Bohren oder Stanzen mit Löchern oder durch Fräsen mit Nuten versehen sind. Durch diese Öffnung gelangt der Schall in das Innere der Platte, wo er durch den Plattenwerkstoff selbst oder durch zusätzlich eingebrachte schallabsorbierende Werkstoffe absorbiert wird. Nach dem heutigen Stand der Technik ist es sehr aufwendig, Platten aus Holzwerkstoff mit akustischen Eigenschaften herzustellen. Dabei ist es unerheblich, ob eine massive Holzwerkstoffplatte, z. B. MDF (mitteldichte Faserplatte) durch aufwendige Fräs- und Bohrarbeiten zu einer akustisch wirksamen Platte umgearbeitet wird oder ob eine Hohlkammerplatte mit akustisch wirksamem Innenkern hergestellt wird. In der-Möbel- industrie werden als Gewichtsgründen sogenannte Leichtbauplatten eingesetzt. Diese Wall or ceiling cladding and furniture elements with sound-absorbing properties are produced in many ways. Usually, the cladding panels are made of wood-based materials, the surface of which are provided by drilling or punching with holes or by milling with grooves. Through this opening, the sound enters the interior of the plate, where it is absorbed by the plate material itself or by additionally introduced sound-absorbing materials. According to the current state of the art, it is very expensive to produce panels of wood-based material with acoustic properties. It is irrelevant whether a massive wood-based panel, z. B. MDF (medium-density fiberboard) is converted by elaborate milling and drilling to an acoustically effective plate or whether a hollow panel is made with acoustically effective inner core. In the furniture industry so-called lightweight panels are used as weight reasons. These
Platten bestehen aus einem Papierwabenkern, der beidseitig mit dünnen Holzwerkstoffplatten beplankt ist. Das Gefüge, der engmaschigen rohen Papierwaben besitzt gute schallabsorbierende Eigenschaften.Plates consist of a paper honeycomb core that is planked on both sides with thin wood-based panels. The structure of the close-meshed raw paper honeycomb has good sound-absorbing properties.
Der Erfindung liegt die Aufgabe zugrunde, eine Leichtbauplatte der aufgezeigten Gattung zu schaffen, die über verbesserte Eigenschaften verfügt.The invention has for its object to provide a lightweight panel of the indicated genus, which has improved properties.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Beplankung ein- oder mehrseitig Durchbrechungen aufweist. Die Beplankung kann durch ein Furnier gebil- det sein, wobei das Furnier eine Stärke von > 0,4 mm aufweisen kann. Es besteht auch die Möglichkeit, die Beplankung durch Dekorfolien, Dekorpapier, Leder, Schichtstoffplatten oder anderen Kunststoffplatten zu bilden.This object is achieved in that the planking one or more openings has. The planking can be formed by a veneer, whereby the veneer can have a thickness of> 0.4 mm. It is also possible to make the planking by decorative films, decorative paper, leather, laminate or other plastic plates.
In Ausgestaltung der Erfindung sind die Durchbrechungen durch Bohrungen, Fräsun- gen oder Ausstanzungen gebildet, die vorteilhafterweise im Abstand von der äußerenIn an embodiment of the invention, the openings are formed by bores, Fräsun- gene or punched, advantageously at a distance from the outer
Begrenzung beginnen. Erfindungsgemäß besitzen die Bohrungen Lochform mit einem 0 von 1 bis 20 mm, wobei die Löcher vorteilhafterweise gleichmäßigen Abstand zueinander haben.Start limiting. According to the invention, the holes have a hole shape with a 0 from 1 to 20 mm, the holes advantageously have a uniform distance from each other.
Bei einer bevorzugten Ausfuhrung ist zwischen dem Papierwabenkern und der Beplankung ein Akustikvlies angeordnet. Es ist vorteilhaft, wenn die Beplankung auf Holzwerkstoffplatten mit einer bevorzugten Stärke von 1 bis 10 mm aufgebracht ist. Die Beplankung und die Holzwerkstoffplatten können beide in einem Arbeitsgang mit Durchbrechungen versehen sein. Der Wabenkern mit einer bevorzugten Stärke zwi- sehen 5 und 100 mm kann aus Papier, Kunststoff oder dünnen Blechen gebildet sein.In a preferred embodiment, an acoustic fleece is arranged between the paper honeycomb core and the planking. It is advantageous if the planking is applied to wood-based panels with a preferred thickness of 1 to 10 mm. The planking and the wood-based panels can both be provided in a single operation with openings. The honeycomb core with a preferred thickness between 5 and 100 mm can be made of paper, plastic or thin sheets.
Die Stirnseiten können bei Erfordernis durch mit einer Beplankung versehenen Stützkanten geschlossen werden. Es besteht auch die Möglichkeit, an den Stirnseiten Mas- sivanleimer anzuordnen. Ein Ausfiihrungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher erläutert. Es zeigen: -The end faces can be closed if required by provided with a planking supporting edges. There is also the possibility of arranging bulkhead lumber on the front sides. An embodiment of the invention is shown in the drawing and will be explained in more detail below. Show it: -
