This consists of organically-bonded plaster, in which are particles (9) larger than the diameter of the holes in the bottom. The plaster can be sprayed into place, and an aqueous copolymer plastics dispersion can be used as the bonding agent. The particles can be grains of marble and of 1.2 to 4 mm. diameter, while that of the holes can be between 1 and 4 mm. Part of the plaster can extend through the holes to the other side. <IMAGE>

Description

Die Erfindung betrifft eine Kassette für Unterdecke, die an einer Gebäude- oder Raumdecke mittels einer Haltekonstruktion insbesondere lösbar aufhängbar oder anbringbar ist und die einen im wesentlichen ebenen Kassettenboden mit einer unteren Sichtseite und vorzugsweise demgegenüber hochstehende Ränder und Flansche für den Angriff einer Halterung hat, wobei der Kassettenboden eine Vielzahl von Lochungen und auf der Sichtseite eine schallschluckende Schicht aufweist, die eine Putzschicht ist. Eine solche Kassette ist in DE-A-3 936 665 beschrieben.The invention relates to a cassette for false ceiling, which on a Building or room ceiling in particular by means of a support structure is detachably attachable or attachable and some essentially flat cassette floor with a lower visible side and preferably contrasting edges and flanges for attacking a bracket, the cassette bottom a large number of perforations and on the visible side a sound absorbing layer has that is a plaster layer. Such a cassette is described in DE-A-3 936 665.

Es sind schallschluckende Bauplatten zur Verkleidung von Innenraumwänden, insbesondere Deckenplatten, also Kassetten der eingangs erwähnten Art, aus gelochtem Metall bekannt, die auf der Sichtseite, also der dem Beschauer zugewandten Deckenseite, mit einer schallschluckenden Schicht oder Folie versehen sind, welche mittels Kleber mit dem Lochblech verbunden ist. Mit Hilfe einer porösen Lackschicht, die auf der Außenseite dieser schallschluckenden Schicht oder Folie angeordnet ist, soll eine Verfestigung und farbliche Gestaltung ohne Beeinträchtigung der schalldämmenden Eigenschaft erreicht werden.They are sound-absorbing building boards for cladding Interior walls, in particular ceiling tiles, so cassettes type mentioned, made of perforated metal, known on the visible side, i.e. the ceiling side facing the viewer, are provided with a sound-absorbing layer or film, which is connected to the perforated plate with adhesive. With help a porous layer of lacquer on the outside of this sound-absorbing layer or film is arranged, a Solidification and color design without affecting the soundproofing property can be achieved.

Es besteht deshalb die Aufgabe, eine Kassette der eingangs erwähnten Art zu schaffen, bei welcher eine zusätzliche poröse Lackschicht auf der schalldämmenden Schicht vermieden werden kann und die akustische Transparenz und das Absorptionsvermögen der Kassette verbessert ist.There is therefore the task of a cassette of the beginning to create mentioned type, in which an additional porous Paint layer on the soundproofing layer can be avoided and the acoustic transparency and absorbency of the Cassette is improved.

Zur Lösung dieser Aufgabe ist die eingangs erwähnte Kassette mit schallschluckender Schicht dadurch gekennzeichnet, daß die Putzschicht aus einem organisch gebundenen Putz besteht und daß in dem Putz Partikel mit einer Korngröße vorgesehen sind, die zumindest teilweise eine Abmessung größer als die Seiten- oder Durchmesserabmessung der Lochungen in dem Kassettenboden haben. Ein organisch gebundener Putz kann auf einfache Weise auf einer Metall-Kassette oder Blech-Kassette aufgetragen werden. Durch die Lochungen wird gleichzeitig auch mechanisch eine gute Haftung erzielt. Gleichzeitig wird erreicht, daß zumindest der größte Teil der Putzmasse auf der Sichtseite bleibt, weil die Korngröße der in dem Putz befindlichen Partikel entsprechend gewählt ist. Trotzdem wird eine akustische Transparenz aufrecht erhalten beziehungsweise verbessert, weil der Putz porös ist und die Porosität bis zu den Lochungen der eigentlichen Kassette und durch diese hindurch reicht.To solve this problem, the cassette mentioned at the beginning is included sound-absorbing layer, characterized in that the Plaster layer from an organic bound plaster and that in the plaster particles with a Grain size are provided, which are at least partially one dimension larger than the side or diameter dimensions of the perforations in the bottom of the cassette. An organically bound plaster can in a simple way on a metal cassette or sheet metal cassette be applied. Through the perforations at the same time mechanically good adhesion achieved. At the same time it is achieved that at least most of the plaster is on the visible side remains because the grain size of the particles in the plaster is chosen accordingly. Nevertheless there is an acoustic transparency maintained or improved because the plaster is porous and the porosity up to the perforations of the actual one Cassette and extends through this.

Es ergibt sich somit eine gute akustische Transparenz und ein hohes Schalldämmvermögen, wobei gleichzeitig aber die Herstellung vereinfacht ist und eine zusätzliche äußere Lackschicht, die auch noch porös sein müßte, vermieden wird.This results in good acoustic transparency and a high sound insulation, but at the same time the production is simplified and an additional outer layer of lacquer, which too should still be porous, is avoided.

Besonders zweckmäßig ist es dabei, wenn der Putz eine Spritzputzstruktur hat und wenn als Bindemittel eine wässrige, copolymere Kunststoffdispersion vorgesehen ist. Eine Spritzputzstruktur ergibt eine etwas rauhe Oberfläche, was der Schalldämmung entgegen kommt. Darüber hinaus kann dabei eine hohe Porosität erreicht werden. Gleichzeitig ergibt sich eine gute Haftung an dem in der Regel aus Blech bestehenden Kassettenboden.It is particularly expedient if the plaster has a spray plaster structure has and if as a binder an aqueous, copolymer Plastic dispersion is provided. A spray plaster structure results a somewhat rough surface, which accommodates the sound insulation. In addition, a high porosity can be achieved. At the same time, there is usually good liability for this cassette floor made of sheet metal.

In der Putzschicht können Körner, vorzugsweise Marmorkörnungen, von 1 Millimeter, 1,2 Millimeter bis 4 Millimeter eingelagert sein und die Lochungen in dem Kassettenboden können einen Durchmesser von 1 Millimeter bis 4 Millimeter haben. Je nach Lochungsgröße können also entsprechende Körnungen innerhalb des Putzes vorgesehen sein, die die Lochungen nicht vollständig abdecken, aber ihrerseits nicht oder nur zu einem Teil in die Lochungen eindringen.Grains, preferably marble grains, can be from 1 millimeter, 1.2 millimeters to 4 millimeters and the perforations in the bottom of the cassette can be one Have diameters from 1 millimeter to 4 millimeters. Depending on Perforation size can therefore be corresponding grits within the Plaster should be provided that the perforations are not complete cover, but in turn not or only partially in the Penetrate perforations.

Dabei kann es vorteilhaft sein, wenn ein Teil des Verputzes durch die Lochungen hindurch bis auf die Rückseite des Kassettenbodens angeordnet ist. Insbesondere der Anteil des Putzes, in dem die Körnungen eingelagert sind, kann durch die Lochungen etwas hindurchdringen und so auch eine formschlüssige mechanische Verbindung zwischen der Putzschicht und dem Kassettenboden herstellen, wenn der Putz abgebunden hat. Darüber hinaus ergibt sich so eine noch dickere Putzschicht, weil diese nicht nur auf der Sichtseite, sondern mindestens im Bereich der Lochungen auch auf der entgegengesetzten Seite des Kassettenbodens angeordnet ist und somit eine größere Dicke und also ein stärkeres Absorptionsvermögen hat.It can be advantageous if a part of the plaster is covered the perforations down to the back of the cassette bottom is arranged. In particular, the proportion of the plaster in which the Grains are stored, something can be done through the perforations penetrate and thus also a positive mechanical Connection between the plaster layer and the cassette floor manufacture when the plaster has set. Furthermore results such an even thicker layer of plaster because this does not only apply to the visible side, but also at least in the area of the perforations arranged on the opposite side of the cassette bottom is and therefore a greater thickness and thus a stronger Has absorption capacity.

Die Putzschicht kann kunststoffgebundener Sand mit eingelagerter Marmorkörnung sein und insbesondere kunststoffgebundener Sand kann die Lochungen ganz oder teilweise durchdringen. Dadurch wird die schon erwähnte mechanische Verbindung der Putzschicht mit dem gelochten Kassettenboden verbessert.The layer of plaster can be plastic-bonded sand with embedded Can be marble grain and in particular plastic-bonded sand penetrate all or part of the perforations. This will make the already mentioned mechanical connection of the plaster layer with the perforated cassette bottom improved.

Eine weitere Ausgestaltung der Erfindung kann darin bestehen, daß im Putz Farbpigmente beigemischt sind. Somit kann der zur Schalldämmung und -absorption dienende Putz eine zusätzliche Funktion erhalten, weil gleichzeitig die Farbgebung einer entsprechenden Kassettendecke in beliebiger Weise beeinflußt werden kann.A further embodiment of the invention can consist in that color pigments are added to the plaster. Thus, the Soundproofing and absorption plaster an additional Preserve function because the color of a corresponding coffered ceiling can be influenced in any way can.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen ergibt sich eine Kassette, bei welcher durch das Aufbringen eines organisch gebundenen Putzes mit Spritzstruktur und einer entsprechenden Marmorkörnung die akustische Transparenz und das Absorptionsvermögen verbessert sind, ohne daß dabei eine poröse Lackschicht benötigt wird. Als Bindemittelbasis kann eine wässrige, polymere Kunststoffdispersion dienen, das heißt es kann ein spezieller Putz Verwendung finden, wie er in der Bauindustrie an sich bekannt ist, so daß es keiner zusätzlichen und aufwendigen Maßnahmen bedarf, um einen entsprechenden Putz herzustellen. Dabei ergibt sich in vorteilhafter Weise eine Schicht, die schwer entflammbar ist und ein relativ niedriges spezifisches Gewicht von nur ca. 1,9 g/cm3 hat. Da einzelne Putzschichtpartikel die Lochungen im Kassettenboden durchdringen können, wird die Haftung gegen mechanische Beanspruchungen verbessert.Especially when combining one or more of the above Features and measures results in a cassette, in which by applying an organically bound plaster with spray structure and a corresponding marble grain acoustic transparency and absorbency are improved, without the need for a porous lacquer layer. As The binder can be an aqueous, polymeric plastic dispersion serve, i.e. a special plaster can be used, as it is known in the construction industry, so that no one additional and complex measures are required to achieve a corresponding To produce plaster. This results in more advantageous Way a layer that is flame retardant and a relative has a low specific weight of only approx. 1.9 g / cm3. There individual plaster layer particles the perforations in the cassette floor can penetrate, the liability against mechanical stress improved.

Eine im ganzen mit 1 bezeichnete Kassette dient dazu, mit weiteren derartigen Kassetten 1 eine Unterdecke zu bilden, die an einer Gebäude- oder Raumdecke mittels einer im Ganzen mit 2 bezeichneten Haltekonstruktion lösbar aufhängbar oder anbringbar ist. Gemäß Figur 1 und 2 hat die Kassette 1 einen im wesentlichen ebenen Kassettenboden 3 mit einer unteren Sichtseite 4 und diesem gegenüber hochstehenden Rändern 5 oder Flanschen, an denen eine Halterung 6 der Haltekonstruktion 2 angreifen kann, wie es in Figur 2 dargestellt ist.A cassette designated as a whole with 1 is used with others such cassettes 1 to form a false ceiling, which on a Building or room ceiling by means of a whole with 2 Retaining structure can be detachably suspended or attached. According to Figure 1 and 2, the cassette 1 has a substantially flat Cassette floor 3 with a lower visible side 4 and this opposite upstanding edges 5 or flanges on which one Bracket 6 of the support structure 2 can attack, as in Figure 2 is shown.

Gemäß Figur 4 hat dabei der Kassettenboden 3 eine Vielzahl von Lochungen 7 und gemäß allen Figuren weist die Sichtseite dieses Kassettenbodens 3 eine schallschluckende Schicht 8 auf.According to Figure 4, the cassette bottom 3 has a variety of Perforations 7 and according to all figures, the visible side has this Cassette floor 3 on a sound-absorbing layer 8.

In den Figuren und dabei vor allen den Figuren 3 und 4 ist schematisiert dargestellt, daß die schallschluckende Schicht 8 eine Putzschicht ist, die zweckmäßigerweise aus einem organisch gebundenen Putz besteht, der eine entsprechend gute Haftung an dem Blech des Kassettenbodens 3 hat. In diesem Putz sind Partikel 9 mit einer Korngröße vorgesehen, die zumindest teilweise in ihrer Abmessung größer als die Seiten- oder Durchmesserabmessungen der Lochungen 7 in dem Kassettenboden 3 sind. Man erkennt vor allem in Figur 4, daß die erwähnten Partikel 9 oder Körnungen teilweise vor den Lochungen 7 zu liegen kommen, trotzdem aber aufgrund der gesamten Porosität des Putzes noch den Schall durchtreten lassen, so daß also die Kassette 1 eine gute akustische "Transparenz" und ein gutes Absorptionsvermögen für Schall hat. Durch die Figuren 2 bis 4 wird außerdem angedeutet, daß der Putz eine Spritzputzstruktur hat. Als Bindemittel kann dabei eine wässrige, copolymere Kunststoffdispersion vorgesehen sein, was zu einer guten Haftung an der metallischen Kassette 1 führt.In the figures and in particular all of the figures 3 and 4 schematically shown that the sound-absorbing layer 8th is a layer of plaster that expediently from an organic bound plaster, which has a correspondingly good adhesion the sheet of the cassette bottom 3. There are particles in this plaster 9 provided with a grain size that is at least partially in their Dimension larger than the side or diameter dimensions of the There are perforations 7 in the cassette base 3. You can see above all in Figure 4 that the particles 9 or grain sizes mentioned come to lie in front of the perforations 7, but nevertheless due to the let the sound pass through the entire porosity of the plaster, so that the cassette 1 has good acoustic "transparency" and has good sound absorption. Through the figures 2 to 4 is also indicated that the plaster is a spray plaster structure Has. An aqueous copolymer can be used as the binder Plastic dispersion can be provided, leading to good adhesion leads to the metallic cassette 1.

Die schon erwähnten Partikel oder Körner 9 in der Putzschicht 8 können Marmorkörnungen sein, deren Abmessungen etwa 1 Millimeter, 1,2 Millimeter bis 4 Millimeter betragen, während die Lochungen 7 in dem Kassettenboden 3 einen Durchmesser von 1 Millimeter bis 4 Millimeter haben können. Vor allem Figur 3 verdeutlicht, daß dabei die Partikel 9 eine unregelmäßige zerklüftete Außenabmessung und Struktur haben, so daß manche Abmessungen geringer, andere aber wieder größer als die der Lochungen 7 sind und somit diese Körner oder Partikel 9 in der Regel nicht in die Lochungen 7 eintreten können, sie aber auch nicht vollständig überdecken.The particles or grains 9 already mentioned in the plaster layer 8 can be marble granules, the dimensions of which are approximately 1 millimeter, 1.2 millimeters to 4 millimeters while the perforations 7 in the cassette base 3 to a diameter of 1 millimeter Can have 4 millimeters. In particular, Figure 3 illustrates that the particles 9 have an irregular, jagged outer dimension and structure, so that some dimensions are smaller, others but again larger than that of the perforations 7 and thus these Grains or particles 9 generally not in the perforations 7 can occur, but also not completely cover them.

In nicht näher dargestellter Weise kann jedoch ein Teil des Verputzes durch die Lochungen 7 hindurch bis auf die Rückseite des Kassettenbodens 3 gelangen und somit nach dem Abbinden des Putzes zu einer hohen mechanischen Festigkeit führen. Dies gelingt umso besser, wenn die Putzschicht 8 kunststoffgebundener Sand mit eingelagerten Marmorkörnungen 9 ist und insbesondere kunststoffgebundener Sand die Lochungen 7 ganz oder teilweise durchdringt.In a manner not shown, however, part of the Plaster through the perforations 7 through to the back of the cassette bottom 3 and thus after setting the Plaster lead to high mechanical strength. This succeeds the better if the plaster layer 8 plastic-bonded sand with embedded marble granules is 9 and in particular plastic-bound sand the holes 7 in whole or in part penetrates.

Es sei schließlich noch erwähnt, daß dem Putz Farbpigmente oder Farbe beigemischt sein kann, so daß die Kassette 1 eine entsprechende Farbgebung erhalten kann, ohne daß dazu eine besondere Lackschicht oder ein zusätzlicher Arbeitsgang erforderlich wären.Finally, it should be mentioned that the plaster color pigments or Color can be added, so that the cassette 1 a can receive appropriate coloring without this special layer of paint or an additional work step required would be.

Insgesamt ergibt sich eine Kassette 1 mit einer guten akustischen Transparenz und einem guten Absorptionsvermögen, die einfach und preiswert herstellbar ist und durch den aufgetragenen Putz auch vielfältige Gestaltungsmöchlichkeiten und optische Effekte erlaubt.Overall, a cassette 1 with good acoustic results Transparency and good absorbency that are simple and is inexpensive to manufacture and also by the plaster applied diverse design options and visual effects allowed.
