Abstract

The noise absorbing panel comprises a rigid outer skin (1). The free space within the skin is filled with a random arrangement of element made of organic or inorganic material held together by an adhesive. The space (3) between the elements are filled with a gas, pref. air. The elements may be in the form of small rods coated with an adhesive which sets after filling of the skin so that there is formed a structure of substantial mechanical strength. The filling may be prepared within an inner skin (4) to facilitate placing into the mould constituted by the above fixed skin.

Description

"Schall-Dämmelement in Tafelform" "Sound insulation element in panel form"

Die Erfindung bezieht sich auf ein Schall-Dämmelement in Tafel form mit einer festen Außenhaut.The invention relates to a sound-insulating element in the form of a panel with a solid outer skin.

Elemente der vorgenannten Art sind bekannt. Als Dmmmaterial werden ilberwiegend Mineralwollmatten verwendet.Elements of the aforementioned type are known. As insulation material Mainly mineral wool mats are used.

Der Nachteil dieser bekannten Elemente besteht darin, daß keine fließende Fertigung möglich ist, da jeweils individuell von Hand das Dämmaterial zugeschnitten und eingebracht werden muß. Diese Fertigungsmethode ist daher dariiberhinaus auch noch äußerst kostenungtinstig. Von der statischen Seite her ist ein weiterer Nachteil dadurch gegeben, daß die Mineralwollftillung keine selbsttragenden Eigenschaften besitzt, so daß zur Erfiillung einer ausreichenden Stabilität des Elementes Vorkehrungen getroffen werden messen, die das Bauelement insgesamt schwerer machen.The disadvantage of these known elements is that no flowing Production is possible because the insulation material is individually cut by hand and must be brought in. This manufacturing method is therefore also still extremely inexpensive. From the static side there is another disadvantage given by the fact that the mineral wool filling has no self-supporting properties so that precautions are taken to ensure sufficient stability of the element measure that make the component heavier overall.

Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, ein Schall-Dämmelement der eingangs beschriebenen Art zu schaffen, welches eine maschinelle Fertigung bei leichtem Gewicht und Optimierung des Schall-Dämmeffektes sicherstellt.The present invention has therefore set itself the task of a To create a sound insulation element of the type described above, which is a machine Production with light weight and optimization of the sound insulation effect ensures.

Zur Lösung dieser Aufgabe wird nach der Erfindung vorgeschlagen, daß der freie Raum zwischen den festen Außenhinten mit einem ungeordneten laufwerk aus organischen und/oder anorganischen mit einem Klebemittel versehenen Materialien ausgefiillt ist, und der zwischen den einzelnen Elementen des laufwerkes befindliche freie Raum mit einem Gas, vorzugsweise Luft, ausgefilllt ist.To solve this problem it is proposed according to the invention that The free space between the fixed outer rear is made up of a disordered drive organic and / or inorganic materials provided with an adhesive is filled out, and the one between the individual elements of the drive free space is filled with a gas, preferably air.

Als besonders zfeckm;ißiv bat sich beziiglich der Einzelelemente des Haufserkes die Ausbildung der Einzelelemente in Stabform erwiesen.As particularly zfeckm; ßiv with regard to the individual elements of the Haufserkes proved the formation of the individual elements in rod form.

Ferner hat sich als zweckmäßig erwiesen, das gesamte ungeordnete laufwerk außen ein- oder mehrseitig von einer Kraut zu umgeben und zusammen mit dieser in den freien Raum zwischen den festen Außenhäuten einzubringen.The entire disordered drive has also proven useful to be surrounded on the outside on one or more sides by a herb and together with this in to bring in the free space between the solid outer skins.

Die Vorteile, die mit dem erfindungsgemißen Schall-D,immelement erreicht werden, bestehen darin, daß aufgrund des Einsatzes von organischen und/oder anorganischen mit einem Klebemittel versehenen Materialien nicht nur eine maschinelle Fertigung möglich wird, sondern auch ein relativ leichtes Gewicht erreicht wird. Darilber hinaus wird der Schall-Dämmeffekt optimal, weil zwischen den Einzelelementen des Ilaufwerkes große, freie, mit Gas, z.B. Luft, geftillte Räume existieren, von denen eine äußerst gtinstige Schall-Dämmwirkung ausgeht. Durch das Aufbringen eines Klebemittels auf die Einzelelemente des ungeordneten flaufwerkes wird dartiber hinaus in vorteilhafter Weise sichergestellt, daß von den Einzelelementen eine feste Verbindung Uber das Klebemittel erreicht wird, so daß das gesamte Laufwerk bereits ffir sich eine selbsttragende Funktion aufweist. Vorteilhaft ist ferner, daß das schalldämmende Elementenhaufwerk außen noch z.B. mit einer Kunststoffhaut, z.B. Folie, umgeben werden kann, so daß weitere einbautechnische Vorteile gegeben sind.The advantages achieved with the sound insulation element according to the invention are, are that due to the use of organic and / or inorganic materials provided with an adhesive are not just machine production becomes possible, but also a relatively light weight is achieved. About it In addition, the sound insulation effect is optimal because between the individual elements of the There are large, free spaces filled with gas, e.g. air, of which emanates an extremely favorable soundproofing effect. By applying an adhesive The individual elements of the disordered drive are also more advantageous Way ensures that from the individual elements a permanent connection About the adhesive is achieved so that the entire drive is already on itself has a self-supporting function. It is also advantageous that the sound-absorbing The heap of elements is still surrounded on the outside e.g. with a plastic skin, e.g. foil can be, so that further installation advantages are given.

Anhand der in den Zeichnungen dargestellten Figuren ist die Erfindung nachfolgend an zwei Ausffibrungsbeispielen näher beschrieben.The invention is based on the figures shown in the drawings described in more detail below using two exemplary embodiments.

Es zeigen: Fig. 1 eine erste Ausftihrungsform der Erfindung Fig 2 eine zweite mögliche Ausführungsform der Erfindung.1 shows a first embodiment of the invention a second possible embodiment of the invention.

Gemäß dem Ausftthrungsbeispiel der Figur 1 besteht das erfindungsgemäße Schall-Dimmelement aus einer festen Außenhaut i. In den freien Raum, der durch die feste Außenhaut gebildet wird, ist ein ungeordnetes Haufwerk 2 aus organischen und/oder anorganischen Materialien eingebracht. Die Einzelelemente 2 des Laufwerkes haben bei dieser Austiibrungsform der Erfindung Stabform. Die einzelnen Stäbchen 2 schließen den in dem ungeordneten Haufwerk freien Raum 3 ein, von dem, wie oben bereits gesagt, eine ausgezeichnete Schall-Dämmwirkung ausgeht. Da die Stäbchen 2 mit einem Klebemittel versehen sind, bilden sie untereinander einen stabilen Tragverband, der durch die feste Außenhaut 1 noch verstärkt wird. Das Ausfflhrungsbeispiel der Figur 2 unterscheidet sich vom Ausfiihrungsbeispiel der Figur 1 nur dadurch, daß das aus den einzelnen Stäbchen 2 bestehende Haufwerk außen mit einer flaut 4 umgeben ist, so daß das ungeordnete Haufwerk bereits in die durch die feste Außenhaut 1 gebildete Form eingelegt werden kann.According to the embodiment of Figure 1, there is the invention Sound dimming element made of a solid outer skin i. In the free space created by the solid outer skin is formed, is a disordered heap 2 of organic and / or introduced inorganic materials. Have the individual elements 2 of the drive rod shape in this embodiment of the invention. Close the individual double crochets 2 the free space 3 in the disordered heap of which, as already said above, emanates an excellent sound insulation effect. Because the chopsticks 2 with an adhesive are provided, they form a stable support structure with each other, which is supported by the solid outer skin 1 is reinforced. The exemplary embodiment in FIG. 2 differs differs from the exemplary embodiment of Figure 1 only in that the the heap that exists on the outside of the individual sticks 2 is surrounded by a flat 4, so that the disordered pile already in the one formed by the solid outer skin 1 Form can be inserted.
