Description

Die Erfindung betrifft eine Unterdecke, Wand- oder Bodenplatte für Brandschutzzwecke, bestehend aus einem einlagig oder vorzugsweise mehrlagig ausgebildeten Decken-, Wand- oder Bodenelement aus einem feuer- und hitzebeständigen Brandschutzmaterial, insbesondere Gipskartonplatten, sowie einer das Element haltenden Tragkonstruktion, wobei das Element mit einer Öffnung zur Anordnung von Installationsteilen oder elektrotechnischen Bauteilen, insbesondere einer Einbauleuchte, versehen ist, wobei im Bereich der Öffnung ein topfartiges Formteil (4) angeordnet ist, welches innenseitig und/oder außenseitig ein eine Dämmschicht bildendes Material aufweist, welches unter der Einwirkung Hitze und/oder Feuer aufbläht und/oder eine Karbonsperrschicht bildet, wobei der Innenraum des Formteiles von der der Tragkonstruktion abgewandten Vorderseite des Elementes zugänglich und zur Aufnahme von Installationsteilen der elektrotechnischen Bauteile bestimmt ist.The invention relates to a false ceiling, wall or floor plate for fire protection purposes, consisting of a single-layer or preferably multi-layered ceiling, wall or floor element of a fire and heat resistant fire protection material, in particular plasterboard, as well as an element holding support structure, wherein the element with an opening for the arrangement of installation parts or electrical components, in particular a recessed luminaire is provided, wherein in the region of the opening a pot-shaped molding (4) is arranged, which has on the inside and / or outside an insulating layer forming material which under the action of heat and / or fire puffs and / or a carbon barrier layer forms, wherein the interior of the molded part of the support structure facing away from the front of the element accessible and intended for receiving installation parts of the electrical components.

Aus der DE 93 18 416 U1 ist eine Unterdecke bekannt, bei der zur Anordnung von elektrischen Einbauteilen, beispielsweise einer Einbauleuchte, das Deckenelement selbst mit einer Öffnung versehen ist, in die ein Feuerschutzkasten von unten her einsetzbar ist. Dieser Feuerschutzkasten besteht in dem Bereich, der dem oberhalb der Brandschutzdecke befindlichen Zwischenraum zugewandt ist, aus Brandschutzmaterial. An seiner Unterseite weist der Kasten eine Platte auf, in die das elektrische Einbauteil eingesetzt ist.From the DE 93 18 416 U1 is a false ceiling is known in which the arrangement of electrical components, such as a recessed light, the ceiling element itself is provided with an opening into which a fire protection box can be inserted from below. This fire protection box consists of fire protection material in the area which faces the intermediate space located above the fire protection ceiling. On its underside, the box has a plate, in which the electrical insert is inserted.

Aufgrund einer solchen Ausbildung ist es möglich, elektrische Installationen in eine Brandschutzdecke einzubauen, ohne dass der Brandschutz verloren geht. Nachteilig bei einer derartigen Anordnung ist aber, dass der Feuerschutzkasten aufwendig aus plattenförmigem Brandschutzmaterial zusammengesetzt werden muss, was den Installationsaufwand erheblich verteuert. Zusätzlich ist es erforderlich, entsprechende Spalte, die beim Einbau eines solchen Kastens in eine Unterdecke unvermeidbar sind, mit Spachtelmasse zu verfüllen, um einen Übertritt von Feuer oder Hitze durch den Spalt auszuschließen.Due to such a design, it is possible to install electrical installations in a fire blanket without the fire is lost. The disadvantage of such an arrangement, however, is that the fire protection box must be complex composed of plate-shaped fire protection material, which considerably increases the cost of installation. In addition, it is necessary to fill with fillers corresponding gaps, which are unavoidable when installing such a box in a false ceiling, to preclude passage of fire or heat through the gap.

Aus der GB-A-22 97 609 ist eine Unterdecke, Wand- oder Bodenplatte gattungsgemäßer Art bekannt.From the GB-A-22 97 609 is a false ceiling, wall or floor plate generic type known.

Aus der GB-A-23 45 125 ist ein Formteil bekannt, das zum Einsatz bei einer Unterdecke, einer Wand- oder Bodenplatte geeignet ist, bestehend aus einem topfartigen Formteil mit innenseitig auf dessen Wandung aufgebrachtem, eine Dämmschicht bildenden Material, mit in die Mündung des Formteils eintauchender und über die Mündung vorragender Platte.From the GB-A-23 45 125 a molded part is known which is suitable for use in a false ceiling, a wall or floor plate, consisting of a cup-shaped molding with the inside applied to the wall, an insulating layer forming material, with immersed in the mouth of the molding and projecting beyond the mouth plate ,

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Unterdecke, Wand- oder Bodenplatte gattungsgemäßer Art zu schaffen, bei der mit einfachen, seriell gefertigten Elementen die Anordnung von Installationsteilen oder von elektrischen Einbauteilen, wie beispielsweise Einbauleuchten, vereinfacht ist.Based on this prior art, the present invention seeks to provide a false ceiling, wall or floor plate generic type, in which with simple, serially manufactured elements, the arrangement of installation parts or electrical components, such as recessed lights, is simplified.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass bei zweilagig ausgebildetem Element das hintere Element eine Öffnung für den Einsatz des Formteiles aufweist, in die das Formteil eingesetzt ist und in die Lochlaibung eintaucht, wobei die Mündung des Formteiles hinter der vorderen Ebene des hinteren Elementes zurückliegt, dass am Formteil mündungsnah federnde Befestigungsklammern gehalten sind, die Einführhilfsschrägen aufweisen und die sich an der Lochlaibung des hinteren Elementes federnd abstützen, wobei die Befestigungsklammern eine Anschlagfläche aufweisen, die in der Montagesolllage an der Vorderseite des hinteren Elements anliegen.To solve this problem, the invention proposes that in a two-ply trained element, the rear element has an opening for the use of the molding in which the molding is inserted and immersed in the hole reveal, the mouth of the molding behind the front plane of the rear element zurückliegt that muzzle close springy mounting brackets are held on the molded part, which have Einführhilfsschrägen and resiliently supported on the hole reveal of the rear element, wherein the Mounting brackets have a stop surface which rest in the mounting target position on the front of the rear element.

Gemäß der Erfindung ist in eine entsprechende Öffnung der Unterdecke oder Platte das topfartige Formteil einzubringen, welches den Einbauraum zur Anordnung von elektrischen Einbauteilen oder Einbauleuchten zur Verfügung stellt. Dieses Formteil kann kostengünstig seriell gefertigt werden und bedarf keiner individuellen Anfertigung.According to the invention, the cup-shaped molding is to be introduced into a corresponding opening of the lower ceiling or plate, which provides the installation space for the arrangement of electrical components or recessed lights. This molding can be manufactured inexpensively serial and requires no individual preparation.

Je nach Erfordernis ist es möglich, das topfartige Formteil lediglich außenseitig, auf der der Unterkonstruktion zugewandten Seite oder lediglich innenseitig, auf der dem unter der Unterdecke oder vor der Wand oder Platte befindlichen Raum zugewandten Seite oder auch beidseitig mit einer entsprechenden Dämmschicht zu versehen. Bei entsprechender Feuer- oder Hitzeeinwirkung wird die Einbauöffnung, die durch das topfartige Formteil belegt wird, durch das aufblähende Material oder das eine Karbonsperrschicht bildende Material geschützt und abgedichtet. Das Material muss dabei nicht selbst formhaltig sein, sondern die Formhaltung des Materials wird durch das topfartige Formteil gewährleistet.Depending on the requirement, it is possible to provide the cup-shaped molded part only on the outside, on the side facing the substructure, or only on the inside, on the side facing the sub ceiling or in front of the wall or plate, or on both sides with a corresponding insulating layer. With appropriate fire or heat exposure, the mounting hole occupied by the cup-shaped molding is protected and sealed by the inflating material or the material forming a carbon barrier layer. The material does not have to be self-contained, but the shape of the material is ensured by the cup-shaped molding.

Entsprechende Materialien, die Dämmschichten bilden können, sind beispielsweise das Material, welches unter der Bezeichnung ROKU-Strip von der Firma Kuhn, unter der Bezeichnung Multifoam von der Firma Multi Vent oder unter der Bezeichnung Karbonschaum A77 von der Firma AIK in Verkehr gebracht werden. In Kombination mit einer entsprechenden Unterdecke oder Platte gemäß Brandschutzklasse F90 (vergleiche auch DIN 18 180) kann mit einer solchen Konstruktion trotz der Anordnung von Einbauteilen in der Unterdecke oder Platte eine entsprechende Widerstandszeit realisiert werden, wie sie zum Beispiel durch die Feuerwider-standsklasse F 90 gefordert ist. Gegebenenfalls können Zuführungskabel oder dergleichen durch entsprechende Lochungen in der Wandung des topfartigen Frontteiles durchgeführt werden, wobei auch diese Lochungen durch die Dämmschichten geschützt sind, die im Falle von extremer Temperatur oder von Feuer aufblähen und eine Sperrschicht bilden, so dass auch im Bereich dieser Lochungen ein Luftdurchzug oder dergleichen ausgeschlossen ist. Es ist somit die notwendige Feuerschutzwirkung realisierbar. Das Formteil kann im Prinzip beliebige Form aufweisen, also zylindrisch oder auch mal mehreckig ausgebildet sein.Corresponding materials that can form insulating layers, for example, the material which is called ROKU-Strip by Kuhn, under the name Multifoam by the company Multi Vent or under carbon fiber A77 from AIK.

Beispielsweise ist es möglich, die Dämmschicht mittels Kleben an dem Formteil 4 zu befestigen. Auch ist es möglich, das Formteil in entsprechendes Material zu tauchen, so dass die Beschichtung mit der Dämmschicht 5 erfolgt. Auch ist es möglich, die Dämmschicht 5 im Wege des Vergusses auf das Formteil 4 aufzubringen. Schließlich kann dass die Dämmschicht bildende Material auch in Form eines formhaltigen Körpers aufgebaut sein, der lediglich auf das Formteil aufgestülpt oder in das Formteil 4 eingesteckt wird. Sofern die Dämmschicht aus einem formhaltigen Körper besteht, kann gegebenenfalls auf die Anordnung des formhaltigen Formteiles 4 teilweise oder vollständig verzichtet werden.The molded part 4 is preferably made of sheet metal, also perforated plate or expanded metal or a grid-like metal skeleton. When using this material, a good thermal conductivity is ensured, so that a good temperature distribution is achieved in the event of fire or the like. In addition, this structure forms a stable support for the foamable insulating material 5. The insulating layer 5 can in a suitable manner with the molding. 4 be connected or just put on this. For example, it is possible to attach the insulating layer by gluing to the molded part 4. It is also possible to immerse the molded part in corresponding material, so that the coating takes place with the insulating layer 5. It is also possible to apply the insulating layer 5 by means of potting on the molded part 4. Finally, that the insulating layer forming material may also be constructed in the form of a form-containing body, which is merely slipped on the molding or inserted into the molding 4. If the insulating layer consists of a form-containing body, it may be possible to dispense partially or completely with the arrangement of the mold-containing molded part 4.

In der Zeichnung ist eine besonders bevorzugte Ausführungsform dargestellt. Hierbei ist das Element 1 zweilagig ausgebildet. Das hintere, in der Zeichnung obere Element 1 weist eine Öffnung für den Einsatz des Formteiles 4 von der Vorderseite her, also von unten in der Zeichnungsfigur, auf. Beim Herstellungsvorgang, der nachfolgend noch beschrieben wird, wird das Formteil 4 in die Öffnung des hinteren Elementes 1 eingesetzt, so dass es geringfügig in die Lochlaibung eintaucht. Die Mündung des Formteiles 4 liegt dabei hinter der vorderen Ebene des hinteren Elementes 1 zurück. Am Formteil 4 sind mündungsnah federnde Befestigungsklammern 10 angeordnet, beispielsweise drei solcher Klammern gleichmäßig auf dem Umfang verteilt. Diese Befestigungsklammern 10 weisen Schenkel 11 auf, die Einführschrägen bilden, so dass beim Einführen des Formteiles 4 in die entsprechende Öffnung von unten nach oben in Figur 1 eine Einführhilfe gebildet ist. Die Schenkel 11 stützen sich in der Montagesolllage an der Lochlaibung des hinteren Elementes 1 federnd ab. Zusätzlich weisen die Befestigungsklammern 10 eine Anschlagfläche 12 auf, die in der Montagesolllage an der Vorderseite des hinteren Elementes 1 anliegen. Der Spalt zwischen dem Formteil 4 und der Lochlaibung ist mit vorzugsweise feuerbeständiger Dichtmasse 13 ausgekleidet und abgedichtet. In dieser Ausführungsform ist in die Mündung des Formteiles 4 eine Platte 14 aus atmungsaktivem, schalldämpfendem, schwer entflammbarem Werkstoff in Form einer Mischung aus Gips und Zellulosefasern eingesetzt. Das Formteil 4 ist innenseitig mit dem die Dämmschicht bildenden Material 5 belegt oder beschichtet, wobei das Material 5 hinter der Mündung des Formteiles 4 geringfügig zurückliegt. Damit ist Freiraum für die Platte 14 geschaffen, die teilweise in die Mündung des Formteiles 4 eingreift und an der Stirnfläche des Materials 5 anliegt, im Übrigen aber über die Mündung des Formteiles 4 vorragt, so dass in der Montagesolllage die Vorderseite der Platte 14 mit der Vorderfläche des hinteren Elementes 1 fluchtet. Um die Platte 14 an dem Formteil 4 schon vor dem Einbau zu fixieren, so dass eine montagefähige Einheit zur Verfügung gestellt ist, weist die federnde Befestigungsklammer 10 eine zusätzliche Haltefläche 15 auf, die in Montagesolllage an der Vorderseite der Platte 14 anliegt. Selbstverständlich ist auch der Spalt zwischen der Platte 14 und der Lochlaibung des hinteren Elementes 1 mit feuerbeständiger Dichtmasse 13 abgedichtet. Die Befestigungsklammer 10 ist ein Blechformteil, aus dem die Halteflächen 12 und 15 ausgeschnitten und nach entgegengesetzten Seiten abgewinkelt sind, wobei die Halteflächen 12,15 nicht in einer Flucht liegen, sondern zueinander versetzt sind, so dass ein Durchlassspalt für die Dichtmasse 13 gebildet ist. Ebenso können der Federarm 11 oder die Federarme (diese können auch mehrfach angeordnet sein) mit entsprechenden Lochungen und Freischnittflächen ausgebildet sein, so dass das Durchtreten der Dichtmasse gewährleistet ist. Die Befestigungsklammer kann zudem mit einem Umschlag um die Mündung des Formteiles 4 greifen und dort steckbefestigt oder rastbefestigt sein.In the drawing, a particularly preferred embodiment is shown. Here, the element 1 is formed in two layers. The rear, in the drawing upper element 1 has an opening for the use of the molded part 4 from the front, ie from below in the drawing figure on. In the manufacturing process, which will be described below, the molding 4 is inserted into the opening of the rear element 1, so that it dips slightly into the hole reveal. The mouth of the molded part 4 is behind the front plane of the rear element 1 back. On the molding 4 are close to the spring resilient Mounting brackets 10 arranged, for example, three such brackets evenly distributed on the circumference. These mounting brackets 10 have legs 11 which form chamfers, so that when inserting the molding 4 in the corresponding opening from bottom to top in Figure 1 an insertion aid is formed. The legs 11 are based in the mounting target position on the hole reveal of the rear element 1 resiliently. In addition, the mounting brackets 10 have a stop surface 12 which abut in the desired mounting position on the front of the rear element 1. The gap between the molding 4 and the hole reveal is lined with preferably fire-resistant sealant 13 and sealed. In this embodiment, in the mouth of the molding 4, a plate 14 made of breathable, sound-damping, flame-retardant material in the form of a mixture of gypsum and cellulose fibers used. The molding 4 is coated or coated on the inside with the insulating layer forming material 5, wherein the material 5 is located slightly behind the mouth of the molded part 4. This space is provided for the plate 14, which engages partially in the mouth of the molding 4 and abuts the end face of the material 5, but otherwise protrudes beyond the mouth of the molding 4, so that in the assembly target position, the front of the plate 14 with the Front surface of the rear Element 1 is aligned. In order to fix the plate 14 on the molded part 4 before installation, so that a unit capable of assembly is provided, the resilient mounting bracket 10 has an additional support surface 15, which rests in the desired mounting position on the front side of the plate 14. Of course, the gap between the plate 14 and the hole reveal of the rear element 1 with fire-resistant sealant 13 is sealed. The mounting bracket 10 is a sheet metal part from which the support surfaces 12 and 15 are cut out and angled to opposite sides, wherein the support surfaces 12,15 are not in alignment, but are offset from each other, so that a passage gap for the sealant 13 is formed. Likewise, the spring arm 11 or the spring arms (these may also be arranged several times) may be formed with corresponding perforations and cut surfaces, so that the passage of the sealant is ensured. The mounting bracket can also grab with an envelope around the mouth of the molding 4 and there plug-mounted or latched.

Bei der Ausführungsform nach Figur 1 ist das vordere Element des zweilagigen Elementes 1 so angeordnet, dass in der Montagesolllage die Einbauöffnung samt in das Formteil 4 eingesetzter Platte 14 überdeckt ist. Sowohl die Platte 14 als auch das vordere Element des zweilagigen Elementes 1 kann zunächst ungelocht sein. Eine entsprechende Lochung kann der Monteur, sobald der Aufbau gemäß Figur 1 beendet ist, einbringen, um nachträgliche Installationsteile, beispielsweise einer Einbauleuchte 2 in die so geschaffene Öffnung einsetzen zu können. Es ist auch möglich, lediglich die Platte 14 vorzulochen und nachträglich das vordere Element des zweilagigen Elementes 1 mit einem entsprechenden Werkzeug zu lochen. Die entsprechende Lochung ist natürlich so anzubringen, dass sie in den Hohlraum mündet, der durch das Formteil 4 gebildet ist.In the embodiment according to FIG. 1, the front element of the two-layered element 1 is arranged so that the installation opening together with the plate 14 inserted into the molded part 4 is covered in the assembly target position. Either the plate 14 and the front element of the two-layer element 1 may initially be unperforated. A corresponding perforation, the fitter, as soon as the structure of Figure 1 is completed, bring in order to use subsequent installation parts, such as a recessed light 2 in the opening thus created can. It is also possible to pre-punch only the plate 14 and subsequently punch the front element of the two-layered element 1 with a corresponding tool. The corresponding perforation is of course to be mounted so that it opens into the cavity formed by the molding 4.

Bei der Montage wird dem Monteur das fertige Element, bestehend aus den Bestandteilen 4,5,10,14 als Vormontageeinheit zur Verfügung gestellt, wobei diese Einheit montagefähig zusammengefügt ist und somit keine verlierbaren oder separat zu haltenden Teile aufweist. Der Monteur bringt dann in die hintere Platte des Elementes 1 eine entsprechende Lochung ein, in die das Formteil 4 eingesetzt und mittels der Befestigungsklammern 10 fixiert werden kann. Anschließend wird die Dichtmasse 13 eingebracht, so dass der Spalt zwischen Formteil 4 und Lochlaibung der Platte 1 ausgefüllt ist. Das Dichtmaterial, welches klebfähig ist, ist in dünner Schicht oder in Form einer Raupe so aufgebracht, dass es über die vordere Fläche des hinteren Elementes 1 vorragt. Anschließend kann die vordere Platte des Elementes 1 aufgebracht werden und befestigt werden, wobei durch die Dichtmasse eine Verklebung im Bereich des Dichtspaltes erfolgt. Je nachdem, ob die Platte 14 vorgelocht ist oder nicht, kann die vordere Platte des Elementes 1 zum Zwecke des Einbringens von Installationen in das Formteil 4 gelocht werden oder auch gleichzeitig die Platte 14 gelocht werden, so dass dann der Einbau eines entsprechenden Installationsteiles, beispielsweise einer Einbauleuchte 2 ermöglicht ist.During assembly, the finished element, consisting of the constituents 4,5,10,14 as a pre-assembly unit, is made available to the installer, this unit being put together ready for assembly and thus having no parts that are to be loosened or kept separate. The fitter then inserts into the rear plate of the element 1 a corresponding hole into which the molded part 4 can be inserted and fixed by means of the fastening clips 10. Subsequently, the sealant 13 is introduced, so that the gap between the molding 4 and hole reveal the plate 1 is filled. The sealing material which is adhesive is applied in a thin layer or in the form of a bead so that it over the front surface of the rear element 1 protrudes. Subsequently, the front plate of the element 1 can be applied and fixed, wherein the sealing compound is adhered in the region of the sealing gap. Depending on whether the plate 14 is pre-punched or not, the front plate of the element 1 can be perforated for the purpose of introducing installations in the molding 4 or at the same time the plate 14 are perforated, so that then the installation of a corresponding installation part, for example a recessed luminaire 2 is possible.

Obwohl das Ausführungsbeispiel die Einbauweise in einer Unterdecke zeigt, ist die Erfindung nicht auf eine solche Einbauweise beschränkt, sondern solche Einbauten können auch in Wandflächen oder entsprechend ausgebildete Bodenflächen erfolgen. Die Form des Formteiles 4 ist vorzugsweise im Querschnitt kreisrund, jedoch sind auch polygonale Ausbildungen möglich und brauchbar. Die zylindrische Form wird vorzugsweise deshalb gewählt, weil es einfacher ist, kreisrunde Lochungen in entsprechende Elemente 1 einzubringen.Although the embodiment shows the way of installation in a false ceiling, the invention is not limited to such a manner of installation, but such installations can also be made in wall surfaces or correspondingly designed bottom surfaces. The shape of the molded part 4 is preferably circular in cross-section, but also polygonal designs are possible and useful. The cylindrical shape is preferably chosen because it is easier to introduce circular holes in corresponding elements 1.

Die Erfindung stellt eine besonders kostengünstige und seriell zu fertigende Installationsmöglichkeit für Unterdecken zur Verfügung.The invention provides a particularly cost-effective and serial to be manufactured installation option for suspended ceilings.
