Abstract

The sound-absorbing ceiling element (20) for the construction of a jointless acoustical ceiling consists of a perforated slab (22) which is covered, room side, on a non-woven layer (24) covering the perforations, with a sound-conducting plaster layer (26) and is backed, on the side facing away from the room, with a sound-insulating layer (28). In order to prevent accumulations of dirt on the plaster layer (26) as a result of the filtering-out of dirt particles in the region of the perforations, it is proposed to cover the sound- insulating layer (28) on its side facing away from the perforated slab (22) with an impervious covering foil (30). <IMAGE>

Description

Die Erfindung betrifft ein schallschluckendes Decken­element für den Aufbau einer fugenlosen Akustikdecke beste­hend aus einer Lochplatte, die raumseitig auf einer die Loch­ungen überdeckenden Vliesschicht mit einer schalldurchlässi­gen Putzschicht abgedeckt und auf der raumabgewandten Seite mit einer Schalldämmschicht hinterlegt ist.The invention relates to a sound-absorbing ceiling element for the construction of a seamless acoustic ceiling consisting of a perforated plate, which is covered on the room side on a non-woven layer covering the perforations with a sound-permeable plaster layer and is deposited on the side facing away from the room with a sound insulation layer.

Dieser Aufbau ist bekannt. Er wird insbesondere für unter die Decke von Räumen abgehängte Akustikdecken verwen­det. Die Schallwellen treten aus dem Raum durch die schall­durchlässige Putzschicht hindurch in die Lochungen der Loch­platte ein und werden in der hinter dieser angeordneten Schalldämmschicht stark gedämpft. Eine aus derartigen Decken­elementen aufgebaute Akustikdecke hat ausgezeichnete schall­technische Eigenschaften.This structure is known. It is used in particular for acoustic ceilings suspended from the ceiling of rooms. The sound waves enter from the room through the sound-permeable plaster layer into the perforations of the perforated plate and are strongly dampened in the sound insulation layer arranged behind this. An acoustic ceiling constructed from such ceiling elements has excellent acoustic properties.

Die Praxis hat jedoch gezeigt, daß derartige Decken als eine Art Schmutzfilter wirken. Denn die Zirkulation er­wärmter Luft durch die Decke oder die Zwangszirkulation bei klimatisierten Räumen führt dazu, daß im Bereich der Lochungen konzentriert von der zirkulierenden Luft mitgeführte Schmutz­teilchen von der Putzschicht ausgefiltert werden. Mit der Zeit werden so an der Putzschicht die Orte der dahinter­liegenden, durch die Putzschicht an sich abgedeckten Lochungen deutlich sichtbar. Die Decke wird unansehnlich.However, practice has shown that such ceilings act as a kind of dirt filter. Because the circulation of heated air through the ceiling or the forced circulation in air-conditioned rooms leads to the fact that in the area of the perforations, dirt particles carried along by the circulating air are filtered out by the plaster layer. Over time, the locations of the perforations behind and covered by the plaster layer become clearly visible on the plaster layer. The ceiling becomes unsightly.

Dieser Effekt wird dann noch verstärkt, wenn die Handwerker zur Erleichterung der Arbeit die Dämmschicht nicht unmittelbar hinter der Lochplatte anbringen, wo wegen der in regelmäßigen Abständen auftretenden Tragprofile die Dämmschicht zugeschnitten werden muß. Wird die Dämmschicht zur Arbeitserleichterung erst über den Grundprofilen ange­ordnet, so befindet sich zwischen der Lochplatte und der Dämmschicht ein erheblicher Abstand, was die Luftzirkulation weiter erleichtert und damit die Verschmutzung der Putz­schicht beschleunigt.This effect is further enhanced if the craftsmen do not apply the insulation layer directly behind the perforated plate to facilitate work, where the insulation layer must be cut to size due to the support profiles occurring at regular intervals. If the insulation layer is first placed over the base profiles to make work easier, there is a considerable distance between the perforated plate and the insulation layer, which further facilitates air circulation and thus accelerates the contamination of the plaster layer.

Aufgabe der Erfindung ist es, die Verschmutzung der Putzschicht aufgrund der Filterwirkung zu vermeiden und die richtige Anordnung der Dämmschicht zu erzwingen. Die Lösung dieser Aufgabe ist im Anspruch gekennzeichnet.The object of the invention is to avoid contamination of the plaster layer due to the filter effect and to force the correct arrangement of the insulation layer. The solution to this problem is characterized in the claim.

Man erkennt, daß hier eine Sandwichplatte entsteht, bei der die einzelnen Schichten, nämlich die Lochplatte mit Vliesschicht und Putzschicht auf der einen Seite und mit Dämmschicht und undurchlässiger Deckfolie auf der anderen Seite von vorneherein zusammengefaßt sind. Es ist damit die richtige Anordnung der Teile aufeinander durch die Vorfabrikation bereits sichergestellt. Dies bewirkt aber auch, daß bereits durch den Strömungswiderstand der jetzt unmittelbar auf der Lochplatte aufliegenden Dämmschicht Die Luftzirkulation vermindert wird. Entscheidend für die Unterbindung der Luftzirkulation ist aber die zusätzliche Anbringung einer undurchlässigen Deckfolie als Deckschicht auf der raumabgewandten Seite. Diese Folie unterbindet nun­mehr den Lufttransport durch die Akustikdecke hindurch in den durch die Abhängung notwendigerweise bestehenden Frei­raum über der Akustikdecke. Das Unterbinden dieser Zirkula­tion und der zusätzliche Strömungswiderstand oberhalb der Löcher der Lochplatte in der Schalldämmschicht bewirkt nun, daß die Luftbewegungen im Deckenelement minimiert werden, so daß es nicht mehr zur gefürchteten Verschmutzung der Putzschicht im Bereich der Lochungen der Lochplatte kommt.It can be seen that here a sandwich panel is created in which the individual layers, namely the perforated panel with fleece layer and plaster layer on one side and with an insulation layer and impermeable cover film on the other side, are combined from the start. The correct arrangement of the parts on top of one another is thus already ensured by the prefabrication. However, this also has the effect that the flow resistance of the insulation layer now lying directly on the perforated plate The air circulation is reduced. The decisive factor in preventing air circulation is the additional application of an impermeable cover film as a cover layer on the side facing away from the room. This film now prevents air transport through the acoustic ceiling into the free space above the acoustic ceiling that is necessarily due to the suspension. The prevention of this circulation and the additional flow resistance above the holes in the perforated plate in the soundproofing layer now have the effect that the air movements in the ceiling element are minimized, so that there is no longer a feared contamination of the plaster layer in the area of the perforations of the perforated plate.

In der Zeichnung, auf die wegen der erfindungswesent­lichen Offenbarung aller im folgenden nicht näher erläuter­ten Einzelheiten ausdrücklich verwiesen wird, ist die Er­findung beispielsweise erläutert. Sie zeigt ausschnitts­weise einen Schnitt durch ein erfindungsgemäßes Decken­element.The invention is explained, for example, in the drawing, to which express reference is made to all details that are not explained in more detail below because of the disclosure essential to the invention. It shows a section of a section through a ceiling element according to the invention.

Eine Deckenaufhängung ist mit dem oberen (in der Figur nicht gezeigten) Ende an der Decke des mit der unter­gehängten Akustikdecke zu versehenden Raumes befestigt. An der Deckenaufhängung 10 ist über Ankerelement 12 das Grundprofil 14 der Deckenaufhängung befestigt. Dieses Grund­profil erstreckt sich über die gesamte Decke und erlaubt auf bekannte Weise das Abhängen der eigentlichen Decken­elemente über Ankerwinkel 16, die mit ihrem Winkel oben das Grundprofil 14 übergreifend einhängbar sind und unten über in der Figur nur symbolisch angedeutete Befestigungselemente 18 mit dem als Sandwichplatte aufgebauten Deckenelement 20 verbunden sind.A ceiling suspension is attached with the upper end (not shown in the figure) to the ceiling of the room to be provided with the acoustic ceiling suspended. The base profile 14 of the ceiling suspension is fastened to the ceiling suspension 10 via anchor element 12. This basic profile extends over the entire ceiling and allows, in a known manner, the actual ceiling elements to be suspended via anchor angles 16, which can be hooked in overlapping the basic profile 14 with their angle at the top, and below with fastening elements 18, only symbolically indicated in the figure, with the ceiling element constructed as a sandwich panel 20 are connected.

Das Deckenelement 20 besteht aus einer größeren Anzahl von Schichten. Tragendes Element ist eine Lochplatte 22 aus Gipskarton. Zwar sind die Lochungen in der Figur regelmäßig eingezeichnet. Sie können auch durchaus eine regelmäßige Verteilung aufweisen. Es hat sich aber in der Praxis gezeigt, daß das Vorsehen von Lochungen unterschied­licher Größe in der Lochplatte die akustischen Eigenschaften noch verbessert. Die Stärke der Gipskarton-Lochplatte kann vorzugsweise zwischen 10 und 15 mm liegen. Die Lochplatte 22 ist auf ihrer unteren, raumseitigen Oberfläche mit einer vorzugsweise aus Glasfasern bestehenden Vliesschicht 24 abgedeckt, die die Lochungen übergreift und somit wieder eine geschlossene Oberfläche bildet. Auf der Vliesschicht 24 trägt das Deckenelement 20 eine dünne, für den Schall durchlässige, optisch aber undurchlässige und im Griff starre Putzschicht 26. Die Putzschicht 26 wird vorzugsweise im Bereich der Stoßfugen zwischen benachbarten Deckenele­menten 20 geschlossen bzw. fugenlos durchgezogen, so daß eine geschlossene Putzschicht entsteht, die den Charakter der von ihr abgedeckten Decke nicht mehr erkennen läßt.The ceiling element 20 consists of a larger number of layers. The supporting element is a perforated plate 22 made of plasterboard. The perforations are regularly drawn in the figure. They can also have a regular distribution. However, it has been shown in practice that the provision of perforations of different sizes in the perforated plate further improves the acoustic properties. The thickness of the plasterboard perforated board can preferably be between 10 and 15 mm. The perforated plate 22 is covered on its lower, room-side surface with a non-woven layer 24, preferably made of glass fibers, which overlaps the perforations and thus again forms a closed surface. On the non-woven layer 24, the ceiling element 20 carries a thin, sound-permeable, optically but impermeable and rigid plaster layer 26. The plaster layer 26 is preferably closed or pulled through in the area of the butt joints between adjacent ceiling elements 20, so that a closed plaster layer arises that no longer reveals the character of the ceiling it covers.

Auf der raumabgewandten Seite weist die das Decken­element 20 bildende Sandwichplatte eine Schalldämmschicht 28 auf. Diese liegt unmittelbar auf der Rückseite der Lochplatte 22 auf, weist aber eine erheblich größere Stärke als diese auf, die mindestens das Doppelte der Stärke der Lochplatte 22 betragen soll, um so die Wirksam­keit der Schallschluckeigenschaften der Akustikdecke sicher­zustellen. Auch die Schalldämmschicht 28 kann aus Glas­fasern oder Steinwolle aufgebaut sein.On the side facing away from the room, the sandwich panel forming the ceiling element 20 has a sound insulation layer 28. This lies directly on the back of the perforated plate 22, but has a considerably greater thickness than this, which should be at least twice the thickness of the perforated plate 22, in order to ensure the effectiveness of the sound-absorbing properties of the acoustic ceiling. The soundproofing layer 28 can also be constructed from glass fibers or rock wool.

Entscheidend ist nun, daß die das Deckenelement 20 bildende Sandwichplatte auf ihrer raumabgewandten Seite als letzte Schicht von einer Deckfolie 30 abgedeckt ist. Diese verhindert, daß durch die Sandwichplatte hindurch eine Luftzirkulation eintritt. Damit wird die schallschluckende Eigenschaft des Deckenelementes nicht beeinträchtigt. Die unangenehme Verschmutzung der Schauseite des Deckenele­mentes 20 wird aber wirkungsvoll unterbunden.It is crucial that the sandwich panel forming the ceiling element 20 is covered as a last layer by a cover film 30 on its side facing away from the room. This prevents air circulation through the sandwich panel. This does not affect the sound-absorbing properties of the ceiling element. The unpleasant contamination of the front side of the ceiling element 20 is effectively prevented.
