The essence of the invention is that the profile strips (4, 5) from the groove (16) of the first, upper panel (2) through to, and including, the groove (17) of the second, lower panel (3), are arranged such that they are offset inwards with respect to the edge surfaces (13) of the panels (2, 3) and, towards the outside, are covered over their entire height by means of at least one covering strip (11) consisting of a flame-retardant or non-combustible material. <IMAGE>

Description

Die Erfindung betrifft ein Deckenelement für eine Brandschutz-Zwischendecke, das mindestens zwei, parallel zueinander sowie im Abstand voneinander angeordnete Platten aus schwer entflammbarem oder nicht brennbarem Werkstoff, insbesondere aus Mineralfaserwerkstoff aufweist, wobei ferner als Abstandshalter und als Träger dienende Profilleisten aus Metall an zwei parallelen Plattenrändern zum Verbinden der Platten vorgesehen sind und mit abgewinkelten Randschenkeln in Nuten liegen, die sich in den Plattenrändern befinden (Siehe z.B. die DE-A-4 036 735 vom gleichen Anmelder).The invention relates to a ceiling element for a fire protection false ceiling, which has at least two, parallel to each other and spaced plates made of flame-retardant or non-combustible material, in particular made of mineral fiber material, further serving as a spacer and as a support profile strips made of metal on two parallel Plate edges are provided for connecting the plates and lie with angled edge legs in grooves that are located in the plate edges (see, for example, DE-A-4 036 735 by the same applicant).

Deckenelemente der genannten Art sind in Gebrauch und erfüllen die an sie gestellten Anforderungen grundsätzlich in zufriedenstellender Weise. Dennoch liegt der Erfindung das Problem zugrunde, diese bekannten Deckenelemente so zu gestalten, daß sie weiterhin erhöhte Brandschutzanforderungen erfüllen.Ceiling elements of the type mentioned are in use and generally meet the requirements placed on them in a satisfactory manner. Nevertheless, the invention is based on the problem of designing these known ceiling elements in such a way that they continue to meet increased fire protection requirements.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Profilleisten von der Nut der oberen Platte bis einschließlich zur Nut der unteren Platte gegenüber den Randflächen der Platten einwärts versetzt angeordnet sind und nach außen über ihre gesamte Höhe mit Hilfe von Abdeckstreifen aus einem schwer entflammbaren oder nicht brennbaren Werkstoff abgedeckt sind.To achieve this object, the invention provides that the profile strips from the groove of the upper plate up to and including the groove of the lower plate are arranged offset inwards relative to the edge surfaces of the plates and outwardly over their entire height with the aid of cover strips from a flame-retardant or non-combustible material are covered.

Die metallischen Teile sind somit besser gegen hohe Temperaturen im Fugenbereich geschützt mit der Folge, daß die tragende Funktion der Profilleisten bei einem Brandangriff von oben oder bei einem Brandangriff von unten länger als bisher erhalten bleibt. Weitere Merkmale der Erfindung gehen aus Unteransprüchen im Zusammenhang mit der Beschreibung und der Zeichnung hervor.The metallic parts are thus better protected against high temperatures in the joint area, with the result that the load-bearing function of the profiled strips is retained longer than before in the event of a fire attack from above or a fire attack from below. Further features of the invention emerge from dependent claims in connection with the description and the drawing.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles, das in der Zeichnung dargestellt ist, näher beschrieben. Dabei zeigen:

Fig. 1:
eine Stirnansicht eines ersten, vollständigen Deckenelementes und eines anschließend angeordneten, abgebrochenen Deckenelementes und

The invention is described below with reference to an embodiment shown in the drawing. Show:
Fig. 1:
an end view of a first, complete ceiling element and a subsequently arranged, broken ceiling element and
Fig. 2:
a detail on a larger scale.

Ein Deckenelement 1 für eine Brandschutz-Zwischendecke umfaßt gemäß Fig. 1 mindestens zwei, parallel zueinander sowie im Abstand voneinander angeordnete Platten 2 und 3 aus schwer entflammbarem oder nicht brennbarem Werkstoff. Insbesondere bestehen die Platten 2 und 3 aus Mineralfaserwerkstoff. Als Abstandshalter und als Träger für die Platten 2, 3 sind Profilleisten 4 und 5 aus Metall vorgesehen und jeweils an zwei parallelen Plattenrändern 6 und 7 zum Verbinden der Platten 2 und 3 unter Bildung des Deckenelementes 1 angeordnet. Die Profilleisten 4 und 5 halten die Platten 2 und 3 im Abstand voneinander und verbinden sie in einer parallelen sowie fluchtenden Lage zueinander.According to FIG. 1, a ceiling element 1 for a fire protection false ceiling comprises at least two plates 2 and 3 made of flame-retardant or non-combustible material which are arranged parallel to one another and at a distance from one another. In particular, the plates 2 and 3 consist of mineral fiber material. Profile strips 4 and 5 made of metal are provided as spacers and as supports for the plates 2, 3 and are each arranged on two parallel plate edges 6 and 7 for connecting the plates 2 and 3 to form the ceiling element 1. The profile strips 4 and 5 keep the plates 2 and 3 at a distance from each other and connect them in a parallel and aligned position to each other.

Um die Profilleisten 4 und 5 vor etwaigen hohen Temperaturen im Bereich des Spaltes bzw. der Fuge 8 zwischen zwei benachbarten Deckenelementen 1 und 9 zu schützen, sind die Profilleisten 4, 5 zum Inneren 10 des jeweiligen Deckenelementes 1, 9 hin versetzt angeordnet und nach außen hin mit Hilfe von mindestens einem Abdeckstreifen 11 aus einem schwer entflammbaren oder nicht brennbaren Werkstoff abgedeckt. Mit ihrer jeweils außen befindlichen Oberfläche 12 liegen die Abdeckstreifen 11 in einer Ebene fluchtend mit den Randflächen 13 der oberen Platte 2 und der unteren Platte 3.In order to protect the profile strips 4 and 5 from possible high temperatures in the area of the gap or joint 8 between two adjacent ceiling elements 1 and 9, the profile strips 4, 5 are arranged offset to the interior 10 of the respective ceiling element 1, 9 and outwards covered with the help of at least one cover strip 11 made of a flame-retardant or non-combustible material. With their respective outer surface 12, the cover strips 11 lie flush with the edge surfaces 13 of the upper plate 2 and the lower plate 3.

Gemäß dem in den Figuren dargestellten Ausführungsbeispiel weisen die Profilleisten 4 und 5 je abgewinkelte Randschenkel 14 und 15 auf, die zur Fixierung an den Platten 2 und 3 dienen und dort in Nuten 16 und 17 greifen, die sich in den Plattenrändern 6 und 7 befinden. Der Steg 18 zwischen den Randschenkeln 14 und 15 kann eben sein oder gemäß Ausführungsbeispiel Sicken 19 aufweisen.According to the embodiment shown in the figures, the profile strips 4 and 5 each have angled edge legs 14 and 15, which are used for fixing to the plates 2 and 3 and engage there in grooves 16 and 17, which are located in the plate edges 6 and 7. The web 18 between the edge legs 14 and 15 can be flat or have beads 19 according to the exemplary embodiment.

Der bzw. die Abdeckstreifen 11 erstrecken sich von der Nut 16 der oberen Platte 2 bis einschließlich zur Nut 17 der unteren Platte 3 und somit über die gesamte Höhe und Länge der Profilleisten 4, 5.The cover strip (s) 11 extend from the groove 16 of the upper plate 2 up to and including the groove 17 of the lower plate 3 and thus over the entire height and length of the profile strips 4, 5.

Die jeweils obere Platte 2 und/oder die jeweils untere Platte 3 können einstückig oder mehrteilig sein. In den Figuren 1 und 2 ist dies durch die Linie 20 angedeutet. Unabhängig von der Ein- oder Mehrstückigkeit der Platten 2, 3 weisen diese einander zugewandte Kantenausnehmungen 21, 22 für den bzw. die Abdeckstreifen 11 auf. Hierdurch ist sichergestellt, daß die Abdeckstreifen 11 mit ihrer außenliegenden Oberfläche 12 mit den freien Randflächen 13 der oberen bzw. unteren Platte 2, 3 fluchten.The respective upper plate 2 and / or the respective lower plate 3 can be in one piece or in several parts. This is indicated by the line 20 in FIGS. 1 and 2. Regardless of the one or more pieces of the plates 2, 3, these have mutually facing edge recesses 21, 22 for the cover strip (s) 11. This ensures that the cover strips 11 are aligned with their outer surface 12 with the free edge surfaces 13 of the upper and lower plates 2, 3.

Zur Erhöhung der Festigkeit kann das Deckenelement 1 mindestens eine, vorzugsweise 2 Traversen 23 aufweisen, die mit Hilfe von Dübeln 24 an den Profilleisten 4, 5 fixiert sind.To increase the strength, the ceiling element 1 can have at least one, preferably 2 cross members 23 which are fixed to the profile strips 4, 5 with the aid of dowels 24.

Auch die Abdeckstreifen 11 bestehen vorzugsweise aus einem Mineralfaserwerkstoff.The cover strips 11 also preferably consist of a mineral fiber material.
