Abstract

The sound proofing layer has an outer soft layer (4) applied to a denser base (2) with a metal mesh (3) embedded between the two layers to give rigidity. The mesh is stiffer than the elasticity of the layers so that they can be bent into the required shapes and held as such. The space between the layers is also provided with profiled grooves (7) for improved sound deadening, as well as providing cable ways. The backing layer has a close spaced cellular structure. The mesh can be held in the ends dof the foam with hooked edges, while the layer itself can be bent over into retaining lips for simple mounting.

Description

Schall-Dämmplatte Sound insulation board

Die Erfindung bezieht sich auf eine aus Schaumstoff bestehende Schall-Dämmplatte mit strukturierter Vorderseite und innerer Schwerschicht.The invention relates to a sound insulation board made of foam with structured front and inner heavy layer.

Die bekannten Schall-Dämmplatten dieser Art sind verbesserungsbedürftig, und zwar im wesentlichen hinsichtlich ihrer Verformbarkeit. Es bereitet nämlich SchwiericJkeiten, die Schall-Dämmplatten mit Krümmungen zu versehen, da sie stets das Bestreben haben, zufolge ihrer innewohnenden Elastizität in ihre Strecklage zurückzukehren.The known sound insulation panels of this type are in need of improvement, essentially with regard to their deformability. Namely, it prepares Difficulties in providing the sound insulation panels with curvatures, as they always strive, according to their inherent elasticity, in their extended position to return.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, eine Schall-Dämmplatte dar in Rede stehenden Art in herstellungstechnisch einfacher Weise gebrauchsvorteilhafter auszugestalten derart, daß neben einer Vergrößerung der Schall-Schluckwirkung eine gute Verformbarkeit erzielt ist.The object of the invention is based on the object of a sound insulation panel the type in question is more advantageous in terms of use in a simple manner in terms of production technology to be designed in such a way that in addition to an increase in the sound-absorbing effect good deformability is achieved.

Gelöst ist wird diese Aufgabe dadurch, daß die Schwerschicht aus einem eingebetteten, unelastisch biegbaren Drahtgitter besteht.This problem is solved by the fact that the heavy layer consists of one embedded, inelastic bendable wire mesh.

Zufolge derartiger Ausgestaltung ist eine gattungsgemäße Schall-Dämmplatte von erhöhtem Gebrauchswert geschaffen. Das unelastisch biegbare Drahtgitter führt zu einem Doppeleffekt: Einerseits läßt sich die Schall-Dämmplatte in die verschiedenen Krümmungen wiegen, in welcher Stellung sie verblibt, und andererseits trägt sie in erheblichem Maße zur Vergrößerung der Schallabsorption bei. Darüber hinaus gestattet das Drahtgitter eine gewichtssparende Bauform. Zufolge seiner Einbettung ist es auch von außen nicht erkannbar. Das Drahtgitter ist im übrigen so beschaffen, daß seine Unelastizität stärker ist als die Elastizität der sie umgebenden Schicht der Schall-Dämmplatte. Unter Umständen ist es möglich, das Drahtgitter' so auszugestalten, daß eine Verkettung der Randzonen der Schall-Dämmplatten möglich ist, was sich für bestimmte Ronstruktionen als günstig erweist. Zu diesem Zweck können bspw. die Enden des Drahtgitters zu Haken und Ösen gebogen sein. Dann ist das Verbinden der Schall-Dämmplatten durch ledigliches Einhaken erreichbar.As a result of such a configuration is a generic sound insulation board created of increased use value. The inelastic bendable wire mesh leads to a double effect: On the one hand, the soundproofing panel can be divided into the various Curvatures weigh in which position it remains, and on the other hand it carries contributes significantly to the increase in sound absorption. In addition permitted the wire mesh has a weight-saving design. It is by virtue of its embedding also not recognizable from the outside. The wire mesh is designed in such a way that its inelasticity is stronger than the elasticity of the surrounding layer of the Sound insulation board. Under certain circumstances it is possible to design the wire mesh in such a way that that a chaining of the edge zones of the sound insulation panels is possible, which is for certain ron instructions proves favorable. To this end you can e.g. the ends of the wire mesh bent into hooks and eyes. Then that's connecting the sound insulation panels can be reached simply by hooking them in.

Herstellungstechnische Vorteile ergeben sich dadurch, daß das Drahtgitter' Gewebestruktur besitzt.Manufacturing advantages result from the fact that the wire mesh ' Possesses tissue structure.

Zur Vergrößerung der Schall-Schluckwirkung trägt die Tatsache bei., daß rückseitig des Drahtyitter's eine mit dicht nebeneinanderliegenden Hohlräumen ausgestattete Schaumstoff zone vorgesehen ist. Die dem Drahtgitter benachbarten Hohlräume bringen vor allen Dingen im Bereich nied'erer Frequenzen eine große Schallabsorbtion und erhöhen. darüber hinaus noch die Bieg'efähigkeit der Schall-Dämmplatte ohne große Querschnittsvariation oder zu große Materialkompressionen.The fact contributes to increasing the sound-absorbing effect., that the back of the wire mesh one with closely spaced cavities equipped foam zone is provided. Those adjacent to the wire mesh Cavities bring a high level of sound absorption, especially in the range of lower frequencies and increase. in addition, the flexibility of the sound insulation board without large cross-section variation or excessive material compression.

Es wird dabei der Effekt ausgenutzt, daß das Drahtgitter die eigentliche Biegeebene darstellt. Durch die Hohlräume sind auch bevorzugte Zonen zur Unterbringung elektrischer Leitungen geschaffen. Beim Verlegen der Schall-Dämmplatten ist dabei nur darauf zu achten, daß die vorzugsweise kanalartig v2rlaufenden hohlräume benachbarter Schall-Dämnplatten in einer Flucht liegen.The effect is used that the wire mesh is the real one Represents bending plane. The cavities also provide preferred accommodation zones electrical lines created. When laying the sound insulation panels is included only towards it make sure that the cavities of adjacent sound insulation panels are in alignment.

SchliGßlich besteht ein günstiges Merkmal noch darin, daß die Hohlräume gewölbeartig gestaltet sind.Finally, there is another favorable feature that the cavities are designed vault-like.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der' Fig. 1 - 3 erläutert. Es zeigt: Fig. 1 eine Draufsicht auf eine Schall-Dämmplatte, teilweise aufgebrochen, Fig. 2 eine Seitenansicht der Schall-Dämmplatte und Fig. 3 einen teilweisen Horizontalschnitt durch die Schall-Dämmplatte in vergrößerter Darstellung.In the following an embodiment of the invention is based on the ' Figures 1-3 illustrate. It shows: FIG. 1 a plan view of a sound insulation board, partially broken away, FIG. 2 shows a side view of the sound insulation board and FIG. 3 shows a partial horizontal section through the sound insulation panel in an enlarged manner Depiction.

Die einen quadratischen Grundriß aufweisende Schall-Dämmplatte setzt sich aus drei Schichten zusammen.The soundproofing panel, which has a square plan, sets made up of three layers.

Es handelt sich hierbei um eine aus Schaumstoff bestehende vordere Schicht 1 und eine rückwärtige Schaumstoffzone 2, zwischen welchen beiden ein unelastisch biegbares Drahtgitter 3 eingebettet ist.This is a front made of foam Layer 1 and a back Foam zone 2, between which both an inelastic bendable wire mesh 3 is embedded.

Die Vorderseite der Schicht 1 ist zur Erzielung einer wirkungsvollen Schallabsorbtion strukturiert. Gebildet ist die Struktur durch eine Vielzahl kreuz und quer hintereinander.gereihter Pyramiden 4.The front of the layer 1 is to achieve an effective Structured sound absorption. The structure is formed by a multitude of crosses and across one another, lined up pyramids 4.

Das ni'n Schwerschicht bildende unelastisch biegbare Drahtgitter 3 weist Gewebestruktur auf, bestehend aus Sett- und Schußabschnitten 5 und 6. Die Unelastizität ist so beschaffen, daß sie größer ist als die Elastizität der beiderseits ihr angeordneten, aus Schaumstoff bestehenden Schichten 1 und 2.The inelastically bendable wire mesh 3, which does not form a heavy layer has a fabric structure consisting of set and weft sections 5 and 6. Die Inelasticity is such that it is greater than the elasticity of either side her arranged, consisting of foam layers 1 and 2.

Beim Ausführungsbeispil drückt sich das Drahtgitter 3 in das Material der weicheren Schicht 1 ein.In the exemplary embodiment, the wire mesh 3 is pressed into the material the softer layer 1.

Gesichert wird diese Lage durch die rückwärtige Zone 2, welche durch Kleben mit der vorderen Schicht 1 verbunden ist.This situation is secured by the rear zone 2, which is through Glue is connected to the front layer 1.

Die Schaumstoffzone 2 formt rückwärtig des Drahtgitters 3 dicht nebeneinanderliegende Hohlräume 7, die, wi Fig. 3 es: zeigt, gewölbeartig gestaltet sind. Es handelt sich dabei. um längsgerichtete, also kanalartige Hohlräume, die bspw. zur Aufnahme nicht dargestellter elektrischer Leitungen dienen können.At the rear of the wire mesh 3, the foam zone 2 forms closely adjacent ones Cavities 7 which, wi Fig. 3 it: shows, are designed like a vault. These are. around longitudinal, so channel-like cavities, which, for example. can serve to accommodate electrical lines, not shown.

Diese Hohlräume begünstigen auch ein Verbiegen der Schall-Dämmplatte, wobei die Biegeebene von dem Drahtgitter 3 dargestellt wird.These cavities also favor bending of the sound insulation board, the bending plane being represented by the wire mesh 3.

Die Enden der Kett- und Schußfäden' 5, 6 können zu nicht dargestellten Haken und Ösen geformt sein.The ends of the warp and weft threads' 5, 6 can not be shown Hook and eye shaped.

Auf diese Weise ist es möglich, mehrere benachbarte Schall-Dämmplatten aneinanderzuhängen. Die Haken und Ösen müssen dann so gestaltet sein, daß sie etwa bündig mit der jeweiligen Außenkante der Schall-Dämmplatte abschließen, um ein dichtes' Verlegen der Schall-Dämmplatten zu gewährleisten.In this way it is possible to have several adjacent sound insulation panels to hang together. The hooks and eyes must then be designed so that they are about flush with the respective outer edge of the sound insulation board to ensure a tight ' Ensure laying of the sound insulation panels.
