Description

Die Erfindung betrifft eine Deckenplatte mit einer nach dem Verlegen unteren, raumseitig angeordneten Oberfläche und mit einer deckenseitigen Oberfläche für eine zugleich Trageprofile aufweisende Zwischendecke.The invention relates to a ceiling tile with a lower, room-side surface after installation and with a ceiling-side surface for a false ceiling which also has support profiles.

Deckenplatten der genannten Art sind seit langem bekannt und dienen zum Herstellen von auch als Unterdecken oder als abgehängte Decken bezeichneten Zwischendecken. Viele öffentliche Gebäude, Verwaltungsgebäude, Schulbauten und Krankenhäuser werden in jüngster Zeit fast ausnahmslos mit abgehängten Zwischendecken versehen und auch mit untergestellten Trennwänden ausgestattet, um die Raumaufteilung den Erfordernissen anpassen zu können und um sie gegebenenfalls auch wieder ändern zu können. Die Trennwände reichen in der Regel nur bis zur Zwischendecke, während sich der über der Zwischendecke befindliche Deckenhohlraum von einer Stützwand bis zur nächsten Stützwand und gegebenenfalls auch über die gesamte Gebäudefläche erstreckt. Verbunden hiermit sind Schallübertragungen auch über Trennwände hinweg in benachbarte Räume.Ceiling panels of the type mentioned have been known for a long time and are used to manufacture false ceilings, also known as suspended ceilings or suspended ceilings. Many public buildings, administration buildings, school buildings and hospitals have recently been fitted with suspended ceilings almost without exception and also equipped with subordinate partitions in order to be able to adapt the room layout to requirements and to be able to change them if necessary. The partitions are enough usually only up to the false ceiling, while the ceiling cavity located above the false ceiling extends from one retaining wall to the next retaining wall and possibly also over the entire building area. Connected with this are sound transmissions also across partitions into neighboring rooms.

Grundsätzlich darf der Schalldurchgang durch die Zwischendecke und den Deckenhohlraum nicht größer sein als der direkte Schalldurchgang durch die Trennwand selbst. Die geforderten Schalldämmwerte sind mit einfachen Deckenplatten nicht zu erzielen und um die geforderten Schalldämmwerte bei herkömmlichen Zwischendecken zu erreichen, wird Mineralwolle zur Schalldämpfung im Deckenhohlraum auf die Zwischendecke aufgelegt.In principle, the sound passage through the false ceiling and the ceiling cavity must not be greater than the direct sound passage through the partition itself. The required sound insulation values cannot be achieved with simple ceiling tiles and in order to achieve the required sound insulation values with conventional false ceilings, mineral wool is used for sound absorption in the ceiling cavity the false ceiling.

Die Verwendung von lose verlegter Mineralwolle auf der Zwischendecke führt zu der gewünschten Schalldämpfung. Die Mineralwolle bringt aber nur dann das gewünschte Ergebnis, wenn sie sorgfältig und ordnungsgemäß verlegt ist. Hiermit sind ein erheblicher Arbeitsaufwand und entsprechende Kosten verbunden. Problematisch ist die Verwendung von lose verlegter Mineralwolle darüber hinaus aber dann, wenn es erforderlich ist, Servicearbeiten oder Reparaturen im Deckenhohlraum vorzunehmen, wozu die Mineralwolle zunächst entfernt und danach wieder ordnungsgemäß verlegt werden müßte. In der Regel geschieht dies nicht mit der Folge, daß es häufig zu einer Verschlechterung der Schalldämmwerte kommt, wenn auch nur geringfügige Instandsetzungsarbeiten oder Reparaturen im Deckenhohlraum vorgenommen werden.The use of loosely laid mineral wool on the false ceiling leads to the desired sound absorption. The mineral wool only brings the desired result if it is laid carefully and properly. This involves a considerable amount of work and corresponding costs. The use of loosely laid mineral wool is also problematic when it is necessary to carry out service work or repairs in the ceiling cavity, for which purpose the mineral wool would first have to be removed and then properly laid again. As a rule, this does not result in the sound insulation values often deteriorating even if only minor repair work or repairs are carried out in the ceiling cavity.

Der Erfindung liegt daher die Aufgabe zugrunde, Maßnahmen vorzusehen, mit deren Hilfe es möglich ist, unmittelbar die schalldämmenden Eigenschaften der Deckenplatte selbst derart zu verbessern, daß es dann nicht mehr erforderlich ist, zusätzlich Mineralwolle lose im Deckenhohlraum zu verlegen.The invention is therefore based on the object to provide measures with the aid of which it is possible to directly improve the sound-absorbing properties of the ceiling panel itself in such a way that it is then no longer necessary to additionally lay mineral wool loose in the ceiling cavity.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Deckenplatte mindestens zwei flächig aufeinander angeordnete, aus schalldämmendem Werkstoff bestehende Plattenelemente umfaßt, zwischen denen eine verbindende, als Schalldämm-Sperrschicht dienende Schicht aus Klebstoff angeordnet ist und wobei ferner die raumseitige Oberfläche der Deckenplatte glatt oder strukturiert und die im eingebauten Zustand oben liegende, deckenseitige Oberfläche mit Vertiefungen und/oder Schallabsorptions-Öffnungen versehen ist.To achieve this object, the invention provides that the ceiling tile comprises at least two flat elements arranged on top of one another, consisting of sound-absorbing material, between which a connecting layer, which serves as a soundproofing barrier layer, is arranged from adhesive, and furthermore the room-side surface of the ceiling tile is smooth or structured and the top surface in the installed state is provided with depressions and / or sound absorption openings.

Zur Verbesserung der Schalldämmung besteht die Deckenplatte somit vorzugsweise aus zwei Plattenelementen, die miteinander verklebt sind. Als Werkstoff für die beiden Plattenelemente dient ein an sich bekanntes, schalldämmendes bzw. schallabsorbierendes Material, wie z.B. eine Mischung aus Mineralwolle, Füllstoff und natürlichem Bindemittel z.B. in Gestalt von Stärke. Das Raumgewicht dieser Plattenelemente kann in einer Größenordnung von 200 kg bis 400 kg pro m³ liegen. Mit Hilfe der Klebstoffschicht wird der Schalldurchgang zusätzlich gedämpft und somit eine insgesamt gute Schalldämmung erzielt. Die Schallabsorptions-Öffnungen auf der deckenseitigen Oberseite der Deckenplatte tragen schließlich zur weiteren Reduzierung der im Deckenhohlraum befindlichen Schallwellen bei, soweit diese überhaupt durch die Deckenplatte bis in den Deckenhohlraum gelangen und sich dann dort ausbreiten. Im Ergebnis erhält man somit durch Verwendung von z.B. zwei oder auch mehr, aus Mineralwolle, Füllstoff und Bindemittel oder aus Perliten (ein anorganisches Kalium-Aluminium-Silikat-Gestein) und Altpapier, Ton sowie Bindemittel bestehenden Plattenelementen eine Deckenplatte, die allen Anforderungen in hohem Maße gerecht wird und das Verlegen von zusätzlich lose aufgelegter Mineralwolle überflüssig macht.To improve the sound insulation, the ceiling panel thus preferably consists of two panel elements that are glued together. The material for the two plate elements is a known, sound-absorbing or sound-absorbing material, such as a mixture of mineral wool, filler and natural binder, for example in the form of starch. The density of these plate elements can range from 200 kg to 400 kg per m³. With the help of the adhesive layer, the passage of sound is additionally damped, thus achieving good sound insulation overall. The sound absorption openings on the ceiling-side upper side of the ceiling panel ultimately contribute to the further reduction of the sound waves located in the ceiling cavity, insofar as they reach the ceiling cavity and then propagate there. In the result gets Thus, by using, for example, two or more plate elements made of mineral wool, filler and binder or perlite (an inorganic potassium-aluminum-silicate rock) and waste paper, clay and binder, a ceiling panel that meets all requirements to a high degree and eliminates the need to lay loose mineral wool.

Weitere Merkmale der Erfindung gehen aus Unteransprüchen in Verbindung mit der Beschreibung und der Zeichnung hervor.Further features of the invention emerge from dependent claims in connection with the description and the drawing.

Die einzige Figur zeigt im Schnitt einen Teil einer Zwischendecke 1 mit zwei seitlich abgebrochenen unterschiedlichen Deckenplatten 2 und 3, die auf Schenkeln eines Trageprofiles 4 aufliegen.The single figure shows in section a part of a false ceiling 1 with two laterally broken different ceiling panels 2 and 3, which rest on the legs of a support profile 4.

Jede Deckenplatte 2 bzw. 3 besteht gemäß Ausführungsbeispiel aus zwei flächig aufeinander angeordneten, z.B. Mineralwolle 5 und Bindemittel 6 aufweisenden Plattenelementen 7 und 8, die ferner mit Hilfe eines zugleich als Schalldämm-Sperrschicht 9 dienenden Klebstoffes miteinander verbunden sind. Für die Herstellung der Plattenelemente 7 und 8 können anstelle von Mineralwolle aber auch andere Werkstoffe wie z.B. Perlite zusammen mit Altpapier und Ton sowie Bindemittel Verwendung finden. Bei den Perliten handelt es sich um ein anorganisches Gestein, das Kalium, Aluminium sowie Silikate enthält und in Form von Sand bzw. fein gemahlen verarbeitet wird.According to the exemplary embodiment, each ceiling plate 2 or 3 consists of two planes arranged one on top of the other, e.g. Mineral wool 5 and binders 6 having plate elements 7 and 8, which are further connected to one another with the aid of an adhesive which also serves as a sound insulation barrier layer 9. Instead of mineral wool, other materials such as e.g. Perlite can be used together with waste paper and clay as well as binders. Perlites are an inorganic rock that contains potassium, aluminum and silicates and is processed in the form of sand or finely ground.

Unter Mineralwolle sind übliche Mineralfasern im weitesten Sinne zu verstehen.Mineral wool is to be understood as common mineral fibers in the broadest sense.

Die im eingebauten Zustand unten liegende oder raumseitige Oberfläche 10 bzw. 10' der Deckenplatten 2, 3 kann glatt oder strukturiert sein, wie dies in der einzigen Figur dargestellt ist. In der Regel weist die Oberfläche 10 einen mehrfachen Farbauftrag auf. Während die raumseitige Oberfläche 10 der Deckenplatte 2 glatt ist, kann sie aber auch entsprechend der Oberfläche 10' der Deckenplatte 3 genadelt sein und somit kleine Schallabsorptions-Öffnungen 11 auf weisen. Die Oberflächen 10 bzw. 10' der Deckenplatten 2, 3 können somit je nach Bedarf glatt oder genadelt, genarbt, gerillt, geriffelt, gelocht oder in sonstiger Weise gestaltet und somit schallabsorbierend sein.The surface 10 or 10 ′ of the ceiling panels 2, 3 lying at the bottom or on the room side in the installed state can be smooth or structured, as shown in the single figure. As a rule, the surface 10 has a multiple application of paint. While the room-side surface 10 of the ceiling panel 2 is smooth, it can also be needled according to the surface 10 'of the ceiling panel 3 and thus have small sound absorption openings 11. The surfaces 10 and 10 'of the ceiling panels 2, 3 can thus be smooth or needled, grained, grooved, corrugated, perforated or designed in any other way and thus be sound-absorbing, as required.

Die anderen, deckenseitigen Oberflächen 12 und 12' der beiden Deckenplatten 2 und 3 sind mit schallschluckenden Vertiefungen und/oder Schallabsorptions-Öffnungen 13 versehen. Unabhängig von der Gestaltung der raumseitigen Oberfläche 10 sind die deckenseitigen Oberflächen 12 somit immer schallabsorbierend gestaltet.The other, ceiling-side surfaces 12 and 12 'of the two ceiling panels 2 and 3 are provided with sound-absorbing depressions and / or sound absorption openings 13. Regardless of the design of the room-side surface 10, the ceiling-side surfaces 12 are thus always sound-absorbing.

Der als Schalldämm-Sperrschicht 9 dienende Klebstoff verbindet die beiden Plattenelemente 7 und 8 vollflächig. Die dem Klebstoff zugewandten Kontaktflächen der beiden Plattenelemente 7 und 8 können unbearbeitet sein. Der zum Verbinden und als Schalldämm-Sperrschicht 9 dienende Klebstoff ist vorzugsweise ein anorganischer Klebstoff.The adhesive serving as a sound insulation barrier layer 9 connects the two plate elements 7 and 8 over the entire surface. The contact surfaces of the two plate elements 7 and 8 facing the adhesive can be unprocessed. The adhesive used for bonding and as a sound insulation barrier layer 9 is preferably an inorganic adhesive.

Das Raumgewicht und/oder die Materialstärke der beiden Plattenelemente 7 und 8 einer jeden Deckenplatte 2, 3 können verschieden sein. Zwingend notwendig ist dies jedoch nicht und ergibt sich auch aufgrund der jeweiligen Anforderungen. Die in der einzigen Figur im Schnitt sowie abgebrochen dargestellten Plattenelemente weisen handelsübliche Abmessungen eines bevorzugten Ausführungsbeispieles auf. Dies bedeutet, daß das Raumgewicht 200 bis 400 kg pro m³ und vorzugsweise 270 bis 350 kg pro m³ beträgt.The density and / or the material thickness of the two plate elements 7 and 8 of each ceiling plate 2, 3 can be different. However, this is imperative not and also results from the respective requirements. The plate elements shown in section and broken off in the single figure have commercially available dimensions of a preferred exemplary embodiment. This means that the density is 200 to 400 kg per m³ and preferably 270 to 350 kg per m³.

Die bevorzugte Deckenplatte 3 besteht aus zwei Plattenelementen 7 und 8 und weist zwischen diesen eine schalldämmende Sperrschicht 9 und schallabsorbierende Öffnungen 11 und 13 in ihren beiden, als Oberseite und als Unterseite dienenden Oberflächen 10' und 12' auf. Die Erfindung ist aber nicht auf diese bevorzugte Ausführungsform beschränkt, vielmehr sind auch noch Abwandlungen möglich, ohne von dem grundsätzlichen Erfindungsgedanken abzuweichen. So versteht es sich, daß der Werkstoff für die Plattenelemente 7 und 8 nicht ausschließlich schalldämmend, sondern auch schallabsorbierend ist.The preferred ceiling panel 3 consists of two panel elements 7 and 8 and has between them a sound-absorbing barrier layer 9 and sound-absorbing openings 11 and 13 in their two surfaces 10 'and 12' serving as the top and bottom. However, the invention is not restricted to this preferred embodiment; rather, modifications are also possible without deviating from the basic concept of the invention. So it goes without saying that the material for the plate elements 7 and 8 is not only sound-absorbing, but also sound-absorbing.
