Description

Die Erfindung betrifft eine schalldämmende oder schalldämpfende Kassettendecke oder -wand nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a sound-absorbing or sound-damping coffered ceiling or wall according to the preamble of patent claim 1.

Unter dem Begriff "Kassetten" werden vorliegend auch langgestreckte Paneele verstanden.The term "cassettes" are understood in the present case as elongated panels.

Kassettendecken oder Kassettenwände werden als abgehängte Decken beziehungsweise aufgesetzte Wände dort eingesetzt, wo eine zusätzliche technische Funktion der Decke beziehungsweise Wand gewünscht ist. Insbesondere werden Decken abgehängt, damit durch sie eine Schalldämmung oder Schalldämpfung erzielt werden kann. So werden beispielsweise in Großküchen, in denen laute Spülmaschinen betrieben werden, solche Kassettendecken oder -wände eingesetzt. Bei bekannten Kassettendecken oder -wänden ähnlich denen der eingangs genannten Art bestehen die Schalldämmelemente im Wesentlichen aus Steinwolle, da Steinwolle eine große Oberfläche und daher sehr gute schalldämmende Eigenschaften aufweist. Damit die Steinwolle insbesondere in einem Dunstbereich von Spülmaschinen oder Kochbereichen nicht mit Wasser- und Fettdämpfen zugesetzt wird - mit Fett zugesetzte Steinwolle ist extrem brandgefährdet -, wird sie paketweise in Kunststofffolie verpackt. Diese Steinwollpakete haben allerdings eine kleinere Oberfläche als die nicht verpackte Steinwolle, und bewirken somit nur eine reduzierte Schalldämmung. Sie sind außerdem kompliziert herzustellen. Müssen sie aus irgendeinem Grund, beispielsweise zur Unterbringung einer Leuchte, eine Düse oder einer Leitung, ein- oder aufgeschnitten werden, ist eine mühsame nachträgliche Abdichtung erforderlich.Cassette ceilings or cassette walls are used as suspended ceilings or patch walls where an additional technical function of the ceiling or wall is desired. In particular, ceilings are suspended so that soundproofing or soundproofing can be achieved through them. Thus, for example, in large kitchens, in which loud dishwashers are operated, such coffered ceilings or walls are used. In known coffered ceilings or walls similar to those of the type mentioned above, the soundproofing elements consist essentially of rock wool, since rock wool has a large surface area and therefore very good sound-insulating properties. So that the rock wool is not added to water and fat vapors, especially in a haze area of dishwashers or cooking areas - rock fat added with fat is extremely fire-prone - it is packaged in packs in plastic film. However, these rock wool packages have a smaller surface than the unpackaged rock wool, and thus cause only a reduced sound insulation. They are also complicated to manufacture. If they have to be cut in or cut for some reason, for example, to accommodate a lamp, a nozzle or a pipe, a tedious subsequent sealing is required.

Eine Kassettendecke oder -wand der eingangs genannten Art ist aus der DE 93 04 227 A1 bekannt geworden. Diese umfasst gewölbte plattenförmige Elemente. Für andere Funktionen als die der Schalldämmung gibt diese Druckschrift keine Lösungshinweise.A coffered ceiling or wall of the type mentioned is from the DE 93 04 227 A1 known. This includes curved plate-shaped elements. For other functions than the sound insulation, this document gives no solution.

Eine Kassettendecke ähnlich derjenigen der eingangs genannten Art ist aus der WO 96/18 005 A1 bekannt. Die Wannen sind gegenüber den Balken der Deckenkonstruktion durch weiches Material vibrationsmäßig entkoppelt; als Schalldämmelemente in den Wannen sind dagegen offenporige Materialien vorgesehen. Dadurch ist die Aufnahme von brennbaren Substanzen, beispielsweise von Fett, begünstigt.A coffered ceiling similar to that of the type mentioned is from the WO 96/18005 A1 known. The tubs are opposite the beams of the ceiling construction vibrationally decoupled by soft material; as sound insulation elements in the tubs, however, open-pored materials are provided. As a result, the absorption of combustible substances, such as fat, favored.

Brandschutzzwecken dient eine in der DE 93 15 184 U1 beschriebene Unterdecke aus mehreren nebeneinander angeordneten plattenförmigen Deckenelementen aus nicht brennbarem bzw. schwer entflammbarem Material. Nähere Angaben zum Material gehen aus dieser Druckschrift nicht hervor; insbesondere auch gibt es dort keine Hinweise zu schalldämmenden Eigenschaften.Fire protection purposes is used in the DE 93 15 184 U1 described sub-ceiling of several juxtaposed plate-shaped ceiling elements made of non-combustible or flame-retardant material. Details on the material are not apparent from this document; In particular, there are no indications of sound-absorbing properties.

Geschlossenporige Schäume in Verbindung mit luftgefüllten Hohlräumen werden in Schalldämmelementen verwendet, die in der US 6 007 890 beschrieben sind. Durch geeignete Dimensionierung werden Helmholtzresonatoren gebildet, welche die Weiterleitung von Schall reduzieren.Closed-cell foams in connection with air-filled cavities are used in sound insulation elements which are used in the US 6,007,890 are described. By appropriate dimensioning Helmholtz resonators are formed, which reduce the transmission of sound.

Aufgabe der vorliegenden Erfindung ist es, eine Kassettendecke oder -wand der eingangs genannten Art so auszugestalten, dass sie neben guten schalldämmenden Eigenschaften Mittel aufweist, um auf einfache Art weitere gewünschte Funktionen zu realisieren und dabei ohne großen technischen Aufwand montierbar und reinigbar ist.Object of the present invention is to design a coffered ceiling or wall of the type mentioned above, that in addition to good sound insulating properties has means to realize in a simple way further desired functions and can be assembled and cleaned without great technical effort.

Diese Aufgabe wird erfindungsgemäß durch eine Kassettendecke oder -wand mit den im Patentanspruch 1 genannten Merkmalen gelöst.This object is achieved by a coffered ceiling or wall with the features mentioned in claim 1.

Wie im Stand der Technik bekannt, ist also ein Material für die Schalldämmelemente vorgesehen, das einerseits gute schalldämmende und schalldämpfende Eigenschaften aufweist, andererseits aber eine geringe Aufnahmekapazität insbesondere für Wasser- und Fettdämpfe besitzt. Das verwendete Material weist eine versiegelte, geschlossene Zellstruktur auf, in die weder Fett noch Flüssigkeit eindringen kann, so dass zusätzliches Einpacken in Folie nicht erforderlich ist. Dies hat den Vorteil, dass das Material bearbeitet, beispielsweise geschnitten oder gebohrt, werden kann, ohne dass anschließend eine erneute Versiegelung notwendig ist oder das Material - wie bei einer Bearbeitung von mit Folie überzogener Steinwolle - erneut mit einer Folie überzogen werden muss. Durch die Bearbeitung büßt das erfindungsgemäße Schalldämmelement demnach nichts von seiner schalldämmenden Eigenschaft ein.As known in the prior art, therefore, a material for the sound insulation is provided, on the one hand has good sound-absorbing and sound-absorbing properties, on the other hand, however, has a low absorption capacity, especially for water and grease vapors. The material used has a sealed, closed cell structure in which neither fat nor liquid can penetrate, so that additional wrapping in film is not required. This has the advantage that the material can be processed, for example cut or drilled, without subsequently requiring a new seal or the material being coated again with a film, as in the case of processing of film-coated rock wool got to. As a result of the processing, the soundproofing element according to the invention accordingly loses none of its sound-insulating property.

Erfindungsgemäß weisen die Schalldämmelemente Aufnahmen für Funktionselemente, nämlich Lampen und/oder Sprinklerdüsen und/oder Lautsprecher und/oder Installationsleitungen, nämlich Wasser-, Gas-, Signal- und/oder Stromleitungen, auf, so dass ein Einbau deutlich erleichtert wird.According to the invention, the soundproofing elements have receptacles for functional elements, namely lamps and / or sprinkler nozzles and / or loudspeakers and / or installation lines, namely water, gas, signal and / or power lines, so that installation is significantly facilitated.

Um Funktionselemente und/oder Installationsleitungen benachbarter Schalldämmelemente ohne großen technischen Aufwand miteinander zu verbinden, weisen die Funktionselemente und/oder Installationsleitungen außerdem erfindungsgemäß lösbare Verbindungselemente, insbesondere Steckelemente, zur Verbindung mit mindestens einem Funktionselement oder einer Installationsleitung eines benachbarten Schalldämmelementes auf.In order to connect functional elements and / or installation lines of adjacent soundproofing elements to one another without great technical effort, the functional elements and / or installation lines also have releasable connecting elements according to the invention, in particular plug-in elements for connection to at least one functional element or an installation line of an adjacent soundproofing element.

Insbesondere im Großküchen, in denen häufig Gasherde mit offenen Flammen betrieben werden und fetthaltige Dämpfe entstehen , ist es von großer Wichtigkeit, dass die Schalldämmelemente schwer brennbar sind.Particularly in commercial kitchens, where gas stoves are often operated with open flames and greasy vapors are formed, it is of great importance that the soundproofing elements are hardly combustible.

Bei einer besonders vorteilhaften Ausführungsform bestehen die Schalldämmelemente aus einem Kunststoffschaum, insbesondere aus einem geschlossenzelligen Polyethylenschaum mit geschlossener Oberfläche, der sehr gute schalldämmende Eigenschaften aufweist und darüber hinaus eine geringe Aufnahmekapazität für Wasser- und Fettdämpfe besitzt. Der Kunststoffschaum weist eine Eigenfestigkeit und Steifigkeit auf und ermöglicht dadurch eine einfache Verarbeitung in Form von Platten oder maßgeschneiderten Elementen, die zur Montage ausgeliefert werden können. Auf Grund seiner Stabilität kann das Material unterschiedlich ohne großen technischen Aufwand befestigt, vorzugsweise gesteckt, verklebt, geklipst oder geschraubt werden.In a particularly advantageous embodiment, the soundproofing elements consist of a plastic foam, in particular of a closed-cell polyethylene foam with a closed surface, which has very good sound-insulating properties and moreover has a low absorption capacity for water and grease vapors. The plastic foam has an inherent strength and rigidity and thereby allows easy processing in the form of plates or custom-made elements that can be delivered for assembly. Due to its stability, the material can be fixed differently without great technical effort, preferably plugged, glued, clipped or screwed.

Bei einer weiteren vorteilhaften Ausführungsform sind die Funktionselemente und/oder Installationsleitungen in den Schalldämmelementen permanent angeordnet. Diese können bereits bei der Herstellung der Schalldämmelemente beispielsweise mit dem Kunststoffschaum eingeschäumt werden, so dass die Schalldämmelemente mit den Installationsleitungen bei der Endmontage nur noch in die entsprechende Wanne einzusetzen sind.In a further advantageous embodiment, the functional elements and / or installation cables are permanently arranged in the soundproofing elements. These can be foamed, for example, with the plastic foam already in the production of sound insulation, so that the sound insulation with The installation cables are only to be inserted in the corresponding tub during final assembly.

Eine alternative vorteilhafte Ausführungsform sieht vor, dass die Funktionselemente und/oder Installationsleitungen in den Schalldämmelementen herausnehmbar angeordnet sind, so dass sie auch nachträglich noch ausgetauscht werden können.An alternative advantageous embodiment provides that the functional elements and / or installation cables are removably arranged in the sound-absorbing elements, so that they can also be subsequently replaced.

The in the FIG. 1 outer tubs 2 are each shown only half.

Die Wannen 2 weisen jeweils rechts dargestellt einen ersten aus einem Wannenboden 3 um 90° abgekanteten, gewinkelten Randflansch 4 und links dargestellt einen zweiten aus dem Wannenboden 3 um 90° abgewinkelten ebenen Randflansch 5 auf. Der erste Randflansch 4 ist in seinem oberen Bereich vom Wanneninneren weg senkrecht nach außen gewinkelt.The troughs 2 each have on the right a first trough bottom 3 folded by 90 °, angled edge flange 4 and on the left side a second trough bottom 3 angled at 90 ° flat edge flange 5. The first Edge flange 4 is angled away from the inside of the tub perpendicular to the outside in its upper region.

Der ebene Randflansch 5 der in Figur 1 mittleren und rechten Wanne 2 wird von dem gewinkelten Bereich des gewinkelten Randflansches 4 der jeweils links angrenzenden Wanne 2 überlappt.The flat edge flange 5 of in FIG. 1 middle and right trough 2 is overlapped by the angled portion of the angled edge flange 4 of each adjacent trough 2 to the left.

Der ebene Randflansch 5 und der benachbarte gewinkelte Randflansch 4 zweier benachbarter Wannen 2 werden mit einem Klammerelement 6 zusammengehalten.The flat edge flange 5 and the adjacent angled edge flange 4 of two adjacent trays 2 are held together by a clamp element 6.

In den Wannen 2 sind quaderförmige Schalldämmelemente 7 aus formstabilem, geschlossenzelligen Polyethylenschaum zur Schalldämmung angeordnet. In den Wannenböden 3 befinden sich eine Vielzahl von Löchern 8, durch die Schallwellen hindurchtreten können.In the tubs 2 cuboid sound insulation elements 7 are arranged from dimensionally stable, closed-cell polyethylene foam for sound insulation. In the tub floors 3 are a plurality of holes 8, can pass through the sound waves.

Die Schalldämmelemente 7 sind vor dem Einbau in die Wannen 2 auf diese zugeschnitten.The sound-absorbing elements 7 are cut to size before installation in the tubs 2.

Die Wannen 2 sind in ein nicht dargestelltes Trägersystem eingesetzt, welches in einer Großküche im Bereich von Spülmaschinen entlang der Decke angeordnet ist, da insbesondere die Spülmaschinen im Betrieb sehr laut sind. Die Wannen 2 sind jedoch im gesamten Decken- oder Wandbereich einsetzbar, um den Geräuschpegel im Arbeitsbereich zu dämmen oder zu senken.The trays 2 are used in a non-illustrated support system, which is arranged in a commercial kitchen in the range of dishwashers along the ceiling, especially since the dishwashers are very noisy during operation. However, the trays 2 can be used throughout the ceiling or wall area to dampen or lower the noise level in the work area.

Um die Kassettendecke 1 zu montieren, werden jeweils zwei Wannen 2 so nebeneinander angeordnet, dass der ebene Randflansch 5 der einen Wanne 2 an den gewinkelten Randflansch 4 der benachbarten Wanne 2 grenzt. Anschließend werden die jeweiligen Schalldämmelemente7 in das Innere der Wannen 2 gelegt. Daraufhin wird das Klammerelement 6 in Figur 1 von oben mit seiner Öffnung voraus über die Anordnung der beiden Randflansche 4 und 5 geschoben.In order to mount the cassette ceiling 1, two trays 2 are arranged side by side so that the flat edge flange 5 of a tub 2 adjacent to the angled edge flange 4 of the adjacent tray 2. Subsequently, the respective Schalldämmelemente7 are placed in the interior of the tubs 2. Then, the clip element 6 in FIG. 1 pushed from above with its opening ahead on the arrangement of the two edge flanges 4 and 5.

In Figur 2 ist eine Wanne 102 der in Figur 1 dargestellten Kassettendecke 1 mit einem bevorzugten Ausführungsbeispiel eines Schalldämmelement 107 isometrisch dargestellt, das quaderförmig ist.In FIG. 2 is a tub 102 of in FIG. 1 shown cassette ceiling 1 with a preferred embodiment of a soundproofing element 107 isometric shown, which is cuboid.

In Figur 3 ist ein zweites Ausführungsbeispiel eines Schalldämmelementes 207 in einer Wanne 202 der in Figur 1 dargestellten Kassettendecke 1 isometrisch dargestellt. Bei diesem weist das Schalldämmelement 207 eine quaderförmige Öffnung für eine Aufnahme 209 auf, in der eine im Schnitt dargestellte Lampe 210 angeordnet ist. Die quaderförmige Öffnung ist durch Herausschneiden eines quaderförmigen Blocks aus dem Schalldämmelement 207 realisiert.In FIG. 3 is a second embodiment of a sound-absorbing element 207 in a trough 202 of the in FIG. 1 shown cassette ceiling 1 is shown isometric. In this, the soundproofing element 207 has a cuboidal opening for a receptacle 209, in which a lamp 210 shown in section is arranged. The cuboid opening is realized by cutting out a block-shaped block from the soundproofing element 207.

In Figur 4 ist das Schalldämmelement 207 mit der vollständigen Lampe 210 gemäß Figur 3 dargestellt, wobei zur Lampe 210 eine starre Stromleitung 211 führt, an deren Ende ein Stecker 212 angeordnet ist. Der Stecker 212 ist kompatibel zu einer nicht dargestellten Buchse eines nicht dargestellten benachbarten Schalldämmelementes, so dass die Stromleitungen der beiden Schalldämmelemente einfach und ohne großen technischen Aufwand miteinander verbindbar sind.In FIG. 4 is the soundproofing element 207 with the complete lamp 210 according to FIG FIG. 3 illustrated, wherein the lamp 210, a rigid power line 211 leads, at the end of a plug 212 is arranged. The plug 212 is compatible with a socket, not shown, of an adjacent sound-deadening element, not shown, so that the power lines of the two sound-absorbing elements can be connected to one another easily and without great technical effort.

Statt aus Polyethylenschaum können die Schalldämmelemente auch aus einem anderen formstabilen geschlossenporigen Material, vorzugsweise Kunststoff, hergestellt sein. Das Material weist vorzugsweise eine Dichte von 32 ± 2 kg/m3 auf. Es sollte temperaturbeständig von -30 Grad Celsius bis +100 °C sein. Vorzugsweise besitzt es eine Wasseraufnahme von maximal 4% bei vollständigem Eintauchen nach 24 Stunden. Die Schalldämmelemente 7 sind daher einzeln oder gemeinsam mit den Wannen 2 beispielsweise in einer Bandspülmaschine oder mit einem Hochdruck- oder Dampfreiniger reinigbar, ohne dass sie ihre Form verändern oder sonst Schaden nehmen. Die Wärmeleitfähigkeit des Materials der Schalldämmelemente beträgt vorzugsweise 0,075 W/mK.Instead of polyethylene foam, the sound-absorbing elements can also be made of another dimensionally stable closed-cell material, preferably plastic. The material preferably has a density of 32 ± 2 kg / m 3 . It should be temperature resistant from -30 degrees Celsius to +100 ° C. It preferably has a water absorption of not more than 4% with complete immersion after 24 hours. The sound-absorbing elements 7 can therefore be cleaned individually or together with the tubs 2, for example in a belt washer or with a high-pressure or steam cleaner, without changing their shape or otherwise being damaged. The thermal conductivity of the material of the soundproofing elements is preferably 0.075 W / mK.

Die Wannen 2 können statt aus Edelstahl beispielsweise auch aus Aluminium bestehen.The trays 2 may instead of stainless steel, for example, also made of aluminum.

Die obige Beschreibung bezieht sich auf eine schalldämmende Kassettendecke; in derselben Weise kann jedoch auch einen schalldämmende Kassettenwand aufgebaut sein.The above description relates to a sound-absorbing coffered ceiling; however, a sound-absorbing cassette wall can also be constructed in the same way.

Zusätzlich oder anstatt einer Lampe können auch ein oder mehrere, auch unterschiedliche andere Funktionselemente, beispielsweise Sprinklerdüsen mit Wasserzuleitungen, Lautsprecher und/oder Piktogramme in den Schalldämmelementen lösbar in entsprechenden Aufnahmen oder auch permanent verlegt sein. Außerdem können auch Durchgangsleitungen oder -rohre permanent oder herausnehmbar eingesetzt sein.In addition to or instead of a lamp, it is also possible to use one or more, also different, different functional elements, for example sprinkler nozzles with water supply lines, Loudspeakers and / or pictograms in the sound insulation elements releasably in appropriate recordings or permanently laid. In addition, through pipes or pipes can be permanently or removably inserted.

Die Installationsleitungen, Wasser-, Strom- und/oder Signalleitungen, können bereits bei der Herstellung der Schalldämmelemente beispielsweise mit dem Polyethylenschaum eingeschäumt werden. Sie können aber auch nachträglich eingebracht werden, indem beispielsweise entsprechende Öffnungen, beispielsweise durch Bohren oder Schneiden, in die Schalldämmelemente eingebracht werden.The installation cables, water, electricity and / or signal lines can already be foamed in, for example, with the polyethylene foam during the production of the soundproofing elements. But they can also be introduced later, for example, by appropriate openings, for example by drilling or cutting, are introduced into the sound insulation.

Statt des Steckers 212 und der Buchse können auch andere komplementäre Verbindungselemente vorgesehen sein.Instead of the plug 212 and the socket, other complementary connecting elements may be provided.

Die Dicke der Schalldämmelemente 7 ist variabel wählbar.The thickness of the sound-absorbing elements 7 is variably selectable.

Die in den Figuren 3 und 4 dargestellte quaderförmige Öffnung kann statt durch Herausschneiden des quaderförmigen Blocks auch bei der Herstellung des Schalldämmelementes von vornherein beispielsweise beim Ausschäumen durch Verwendung einer Form ausgespart werden.The in the FIGS. 3 and 4 shown rectangular opening can be omitted instead of cutting out of the block-shaped block in the production of the soundproofing element from the outset, for example, during foaming by using a mold.

Die Schalldämmelemente sind sowohl zur Schalldämmung als auch zur Schalldämpfung verwendbar.The soundproofing elements can be used for both soundproofing and soundproofing.
