Abstract

A ceiling tile which is held by a support, consists of a frame (1) and a plate shaped member made of a sound damping material molding (6). The thickness of the frame is greater than the molding thickness. The upper and lower outside sections of the frame are supplied with a covering, e.g. of polyvinylchloride (PVC).

Description

Die Erfindung betrifft eine Deckenplatte zur Platzierung in einem Hängesystem.The invention relates to a ceiling plate for placement in a hanging system.

Derartige Deckenplatten werden insbesondere dazu eingesetzt, die akustischen Gegebenheiten von Räumen zu beeinflussen. Sie können daneben aber auch optische Effekte bewirken und der Wärmedämmung dienen.Ceiling panels of this type are used, in particular, for the acoustic conditions of influencing rooms. You can also use optical effects effect and serve thermal insulation.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine besonders einfach ausgebildete und kostengünstig herstellbare Deckenplatte zu schaffen, mit der die Akustik von Räumen maßgeblich beeinflusst werden kann.The object of the present invention is to be particularly simple trained and inexpensive to manufacture ceiling tile with which the Room acoustics can be significantly influenced.

Erfindungsgemäß ist zur Lösung der Aufgabe eine Deckenplatte vorgesehen, die gekennzeichnet ist durch einen rechteckigen formstabilen Rahmen, einen dem Rahmen angepassten und darin formschlüssig plazierten plattenförmigen Formkörper aus schalldämmendem Material, wobei die Dicke des Rahmens größer ist als die Dicke des Formkörpers, und eine an der oberen und /oder der unteren Außenseite des Rahmens verlaufende, jeweils den Formkörper mit Abstand überspannende Abdeckung.According to the invention, a ceiling plate is provided to solve the problem, which is marked is due to a rectangular, dimensionally stable frame, the frame adapted and positively placed plate-shaped molded body soundproofing material, the thickness of the frame is greater than the thickness of the Shaped body, and one on the upper and / or the lower outside of the frame extending cover, each spanning the molded body by a distance.

Diese Formplatte ist besonders stabil und hält den Formkörper genau platziert an dem für ihn bestimmten Ort. Das Material des Formkörpers kann dabei so gewählt werden, dass es schall- und/oder wärmedämmend und/oder feuerhemmend ist. Bevorzugt wird als solches Material Steinwolle verwendet.This molded plate is particularly stable and holds the molded body precisely on the place intended for him. The material of the molded body can be chosen that it is sound and / or heat insulating and / or fire retardant. Is preferred rock wool is used as such material.

Der Rahmen ist vorzugsweise aus Metall, insbesondere aus Stahlprofilen gebildet.The frame is preferably made of metal, in particular steel profiles.

Erfindungsgemäß ist weiter vorgesehen, dass der Rahmen auf seiner Unterseite mit den Formkörper tragenden, aufeinander zu vorstehenden Tragelementen versehen ist. Diese Tragelemente können flach ausgebildet sein, als Stege längs dem Innenrand des Rahmens verlaufen oder auch zum Tragkörper hin aufgewölbt verlaufen. Im letzteren Falle wird die Unterseite des Formkörpers in größerem Abstand zur Bodenfläche des Rahmens gehalten.According to the invention it is further provided that the frame on its underside the molded body-supporting, protruding support elements is provided. These support elements can be flat, as webs along the inner edge of the Frame run or also arched towards the supporting body. In the latter Trap the bottom of the molded body at a greater distance from the bottom surface of the Held frame.

Erfindungsgemäß kann der Rahmen mit nach außen abstehenden Auflagem versehen sein. Diese Auflager eignen sich dazu, auf entsprechenden Aufnahmen des Hängesystems zur Auflage zu kommen und die Deckenplatte zuverlässig zu halten. Die Auflager können über die gesamten Seitenlängen des Rahmens sich erstrecken.According to the invention, the frame can be provided with outwardly projecting supports his. These supports are suitable for use on the corresponding fixtures of the hanging system come to rest and hold the ceiling tile reliably. The supports can extend over the entire side lengths of the frame.

Die Abdeckungen können als Kunststofffollien, z. B. PVC-Folie, ausgebildet sein, aber auch aus textilem Material oder aus einem anderen für den jeweiligen Einsatz zu bestimmenden Material gewählt sein. Sie können mit dem Rahmen insbesondere durch Kleben ve rbunden sein.The covers can be used as plastic sheets, e.g. B. PVC film, but also from textile material or from another for the respective use material to be chosen. You can go through with the frame in particular Bonding be connected.

Als Material für den Formkörper eignet sich insbesondere Steinwolle. Der Formkörper kann außenseitig mittels einer Folie, z.B. einer Aluminiumfolie, abgedeckt sein.Rock wool is particularly suitable as the material for the shaped body. The molded body can be externally by means of a film, e.g. an aluminum foil.

Die Deckenplatte gemäß der Ausführungsform nach den Figuren 1 und 2 besteht aus einem Metallrahmen 1, vorzugsweise aus Stahl, mit Seitenwänden 2, oberen Wangen 3 und unteren Wangen 4. An die unteren Wangen 4 schließt sich jeweils ein aufwärts gewölbter Abschnitt 5 an. Die Wangen 4 und 5 bilden Tragelemente, auf denen ein Formkörper 6 mit Abstand über einer Abdeckung 7 ruht, die wiederum mit den Wangen 4 verbunden, vorzugsweise verklebt ist. Die Abdeckung 7 kann aus einer Kunststofffolie, aus textilem Material oder aus einem anderen für die jeweilige akustische Situation geeigneten Materialen bestehen.The ceiling plate according to the embodiment according to Figures 1 and 2 consists of a metal frame 1, preferably made of steel, with side walls 2, upper cheeks 3rd and lower cheeks 4. The lower cheeks 4 each have an upward connection arched section 5. The cheeks 4 and 5 form support elements on which a Shaped body 6 rests at a distance above a cover 7, which in turn with the cheeks 4 connected, preferably glued. The cover 7 can be made from a Plastic film, from textile material or from another for the respective materials suitable for the acoustic situation.

Der Formkörper 6 wird von den Abschnitten 5 in Anlage an der Innenseite der Wangen 3 gehalten. Er besteht vorzugsweise aus Stahlwolle.The shaped body 6 is in contact with the sections 5 on the inside of the cheeks 3 held. It is preferably made of steel wool.

Auf den Außenseiten dieser Wangen ist jeweils eine Abdeckung 17 vorgesehen, die jeweils zu der äußeren Fläche des Formkörpers 6 einen Abstand aufweisen. Die Abdeckungen 17 sind mit den Außenflächen der Wangen 15, 16 fest verbunden, insbesondere verklebt. Es werden somit Hohlräume zwischen den Außenflächen des Formkörpers 6 einerseits und den Abdeckungen 17 andererseits gebildet. Es ist selbstverständlich möglich, eine solche Abdeckung nur auf der einen Seite der Deckenplatte vorzusehen.FIG. 7 shows a metal frame 1 of the type described. Figure 8 shows in this Frame 1 a molded body 6, the steel profiles here upper cheeks 15 and have lower cheeks 16 and the molded body sits between these cheeks. On the Outside of these cheeks, a cover 17 is provided, each of which is closed have a distance from the outer surface of the molded body 6. The covers 17 are firmly connected to the outer surfaces of the cheeks 15, 16, in particular glued. There are thus voids between the outer surfaces of the molded body 6 on the one hand and the covers 17 formed on the other hand. It is of course possible to get one provide such cover only on one side of the ceiling plate.
