Abstract

In a fire-resistant ceiling, non-flammable panels (18) are supported by spring strips (23) made of the same non-flammable material, which engage in the grooves of adjacent panels and have a greater width (b) than the mutually facing grooves (22) of the adjacent panels (18). The springs have on their undersides (30) facing the room a coating (28) or covering (29) and serve simultaneously as supporting members and sound-absorbing members. As a result of this arrangement, a grillage for the ceiling is not necessary. The ceiling therefore has a low overall height and good sound-proofing. <IMAGE>

Description

Die Erfindung betrifft eine feuerwiderstandsfähige Unterdecke mit genuteten, durch Federn verbundenen, nicht brennbaren Paneelen, die mit einer Tragkonstruktion an einer tragenden Decke aufgehängt sind.The invention relates to a fire-resistant false ceiling with grooved, spring-connected, non-combustible panels which are suspended from a supporting structure by a supporting structure.

Unbrennbare, feuerwiderstandsfähige Paneele haben ein verhältnismäßig hohes Gewicht, so daß eine hieraus hergestellte Unterdecke eine kräftige Tragkonstruktion haben muß, mit der sie an der tragenden Geschoßdecke abgehängt wird. Bekannte, feuerwiderstandsfähige, abgehängte Decken haben deshalb einen Trägerrost aus einander kreuzenden Quer- und Längsträgern aus Metall, der mit Hängestangen od.dgl. an der tragenden Geschoßdecke befestigt ist. An den Flanschen der unteren Träger dieses Trägerrostes sind dann die Paneele mit Klipsen befestigt, wobei aneinanderstoßende Paneele durch Federleisten verbunden sind, die in die seitlichen Nuten benachbarter Paneele eingeschoben werden.Incombustible, fire-resistant panels have a relatively high weight, so that a false ceiling made from them must have a strong supporting structure with which it is suspended from the load-bearing ceiling. Known, fire-resistant, suspended ceilings therefore have a support grate made of intersecting cross and longitudinal beams made of metal, or the like with hanging bars. is attached to the supporting floor ceiling. The panels are then fastened with clips to the flanges of the lower supports of this support grate, the abutting panels being connected by spring strips which are inserted into the lateral grooves of adjacent panels.

Bei dieser bekannten Ausführungsform beansprucht der Trägerrost von einander kreuzenden Längs- und Querträgern viel Raum unter der tragenden Decks. Außerdem ist die Tragkonstruktion solbst sehr schwer, und die Unterdecke ist akustisch unbefriedigend, da sie den Raumschall nicht dampft.In this known embodiment, the supporting grating of longitudinal and transverse beams crossing each other is claimed like a lot of space under the load-bearing decks. In addition, the supporting structure itself is very heavy, and the suspended ceiling is acoustically unsatisfactory because it does not dampen the room sound.

Aufgabe der Erfindung ist es, diese Nachtelle zu verzusiden und eine feuerwiderstandsfählge Unterdecke zu schaffen, die eine goringe Esuhöhe mit hoher mechaniacher Festigksit vereinigt und eine gute Schallabsorption aufweist.The object of the invention is to avoid this nightfall and to create a fire-resistant underlay which combines a low Esuhöhe with high mechanical strength and has good sound absorption.

Die as Aufgabe wird mit der Erfindumg dadurch gelöst, daß die Unterdecks an der Tragkonstruktion mit den in die Huten benachbarter Paneele eingreifenden Fedem befestigt ist, die an ihren, den Raum zugekehrten Uhterseiten eine Be schi chtung oder Abdeckung aufweisen.The object is achieved with the invention in that the lower decks are fastened to the supporting structure with the springs engaging in the hats of adjacent panels, which have a cover or cover on their underside facing the space.

Die se Konstruktien hat den Vorteil, daß ein Trägerrost nickt erforderlich ist, da die zwischen den Paneelen angeordneten, sus dem gleichen, feuerwiderstsndfähigen Material wie die Paneele bestahanden Federn die Aufgabe der Träger übornehmen, an denen die Hänge stäbe oder Tragelemente unmittelbar befestigt sind, die dann ihrerseitg entweder direkt an der tragenden Oberdecke oder an unter diese angeordneten Trägern hängen. Die feuerwideretandfähigen Pansele und die air verbindenden Federn bestehen zweckmäßig aus Asbestsilicat-Platten, die eine besonders hohe Feusrwidsrstandsfähigkeit sufweisen. Da die Federn eine größere Breite haben als die beiden einander zugekehrten Huten der banachbartan Paneele, ergibt sich eine profilierte Unterfiächs der Desks mit einer Vielzahl von Vertiefungen, die eine günstigs Schalldämpfungswirkung entfalten.The se constructs has the advantage that a support grid nodding is required, since the springs arranged between the panels, the same fire-resistant material as the panels, are provided with springs, which assume the task of the supports, to which the hangers or support elements are directly attached, the then hang either directly on the load-bearing top cover or on beams arranged underneath it. The fire-resistant panels and the air-connecting springs suitably consist of asbestos silicate panels, which have a particularly high resistance to fire. Since the springs have a larger width than the two facing hats of the banachbartan panels, there is a profiled lower surface of the Desks with a large number of recesses, which have a favorable sound absorption effect.

Be sonders zweckmäßig ist es, wenn die Federn sinen den Paneelen analogen, I-förmigen Querschnitt mit seitlichen Längsachlitzen haben, in welche mindestens einer der die Nuten begrenzenden Flanscha der Panesle paßt. Durch diese Formgebung erhalten die als Träger dienenden Federn ain sehr günstiges widerstandamomant, so daß aie das verhältnismäßig hohe Eigengewicht der abgehängten Decke gut aufnehmen können. Außerdem bieten sie in Brandfall dem Wasserdruck eines von unter gegen die Unterdecke gerichteten Löschwasserstrahles einen genügend hohen Widerstande so daß die Unterdecke auch bein Löschen nicht zerstört wird.It is particularly useful if the springs have the panels analog, I-shaped cross-section with lateral longitudinal slots, into which at least one of the flanges of the panels that delimit the grooves fits. This shape gives the springs serving as supports ain very inexpensive resistance-resistant, so that they can easily absorb the relatively high weight of the suspended ceiling. In addition, in the event of fire, they offer a sufficiently high resistance to the water pressure from a fire water jet directed under the suspended ceiling so that the suspended ceiling is not destroyed even when extinguished.

Nach einen weiteren Merkmal der Erfindung können die unteren Flanschen der Federn in die Nuten der Panesle und die oberen Flanschen der Paneele in die Nuten der Federn eingreifen. Diese Ausgestaltung hat den Vorteilt daß die Fugen zwischen den Panselen sehr dicht werden, da eine Art Labyrinthdichtung entstoht, die in Brandfall Rauch und Brandgase nicht durch die Unterdecke hindurchtreten läßt. Wenn die Unterdecke unmittelbar unter einer Trägerlage befestigs wird, wird diese Tragkonstruktion im Abstand von den Paneelen gehalten, da die Ober seits der Federlsisten höher lisgt als die Oberseits der Pansele.According to a further feature of the invention, the lower flanges of the springs can engage in the grooves of the panels and the upper flanges of the panels in the grooves of the springs. This configuration has the advantage that the joints between the panels become very tight, since a kind of labyrinth seal is emitted, which in the event of fire does not allow smoke and combustion gases to pass through the false ceiling. If the false ceiling is fastened directly under a support layer, this support structure is kept at a distance from the panels, since the upper side of the feather is higher than the upper side of the panel.

Die Dicke von mindestans zwei einander gegenüberliegenden Flanschen der Feder kann kleider sein als die lichte Nette der Nuten in den Paneelen. Dies hat den Vorteil, daß unterhalb der Feder in dio Nuton dar Paneele noch eine Abdeckung, beispielsweise sin Mineralfaserstreifan od.dgl. nachträglich eingsschobeen werden kann, wslcher die Unterseite der Feder abdeckt und die an den Federn angreifanden Befastigungsmittel, beispielsweise Schrauben oder Haiteplstten aus Metall vor der Einwirkung des Feuers in Brandfall schützt.The thickness of at least two opposite flanges of the tongue can be less than the clear cut of the grooves in the panels. This has the Advantage that below the tongue in the Nuton dar panels still a cover, for example sin mineral fiber stripe or the like. can be pushed in later, which covers the underside of the spring and protects the fasteners attacking the springs, such as screws or metal shavings, from the effects of fire in the event of a fire.

Each einen weiteren Merkmal der Erfindung kann die Dicke von mindestans einander gegenüberliegenden Flanschen der Feder der lichten Weite der Nuten in den Panselen entsprachen. Die an diese Flanschs angrenzende Unterteits der Feder hat dann zweckmäßig eine in Querachnitt schwelbenchwanzförmige Rinne, in die ains feusrwidsrstandsfähige Abdeckung eingelegt werden kann.According to a further feature of the invention, the thickness of at least opposite flanges of the tongue can correspond to the inside width of the grooves in the panels. The lower part of the spring adjoining these flanges then expediently has a flank-tail-shaped groove in the cross-section into which a fire-resistant cover can be inserted.

Die Beschichtung der Unterseite der Feder kann eine Beflockung aus Kunststoff oder Asbestfasern sein, die an einer auf der Feder aufgebrachten Klebsmittelschicht haften. Eine solche Beflockung gewährleistet eine besonders gute Schallabsorption und kann in einfacher Weise dadurch hergestellt werden, daß Fasern oder Flocken unterechi adlicher Länge auf aine Klebemittelschicht gestreut und dann eloktrostatisch aufgerichtet werden. Die Fasern stehen nach dem Abbinden des Klebemittels dann aufrecht, so daß eine Art Pelz entsteht. Neben einer gutan Schallabsorption entwickelt eine solche Beflockung auch eine hohe Feuerwiderstandsfähigkeit, wenn die Fasern oder Flocken aus nicht brennbaren Stoffcn, wie beispielsweise Asbest oder Mineralfasern bestehen.The coating on the underside of the spring can be flocking made of plastic or asbestos fibers that adhere to a layer of adhesive applied to the spring. Such flocking ensures a particularly good sound absorption and can be produced in a simple manner by sprinkling fibers or flakes of a different length on a layer of adhesive and then erecting them electrostatically. After the adhesive has set, the fibers stand upright so that a kind of fur is created. In addition to good sound absorption, such flocking also develops high fire resistance if the fibers or flakes consist of non-combustible materials such as asbestos or mineral fibers.

Anstelle dar Beschichtung mit schellebeorhierenden, feuerwiderstandafNhigen Stoffen kann die Unterseite der Federn auch mit einem dünnen Streifen aus unbrennbarem Meterial, beispielewaise mit einem Kineralfaserstreifen oder einem Asbestschaumztreifen

in dem Keichnungen ist mit 10 eine tragande Geschoβ-decke bezeichnet, die auf tragenden Wänden 11 und 12 aufliegt und als Stahlbeten-Verbundträgerdecke außgebildet ist. Die Verbundträgerdecke bestaht aus Stahlträgern 13 mit Normalprofil, deren Obergurte 14 mit einer Druckplatte 15 aus Stahlbston fest verbunden aind. Um die Stahlträger 13 im Falle eines Brandes vor Feuereinwirkung zu schützen und gleichzeitig einna glatte, ansprechende Deckenuntersicht zu erzielen und die Akustik des Raumen zu verbessern, ist eine fouerwiderstandsfählige Unterdecke 16 vergesehen, die mit Tragvorrichtungen 17 an den Stahlträgern 13 der tragenden Decke 1o aufgehängt ist.in the Keichungen with 1 0 is a traga floor ceiling, which rests on load-bearing walls 11 and 12 and is designed as a steel-beet composite carrier ceiling. The composite beam ceiling consists of steel beams 13 with a normal profile, the top chords 14 of which are firmly connected to a pressure plate 15 made of steel concrete. In order to protect the steel beams 13 from fire in the event of a fire and at the same time to achieve a smooth, attractive ceiling view and to improve the acoustics of the room, a resistance-resistant false ceiling 16 is provided, which is suspended from the steel beams 13 of the load-bearing ceiling 10 with support devices 17 .

Die Unterdecke 16 besteht aus mehreren, parallelen, im Abstand nebeninander engeordnsten, nicht brannbaren Paneelen 18 aus Asbestailicat, die an ihrar Unterseite und ggfs. auch an dan Längsseiten der unteren Fleneche 2o mit einem Holzfurnier oder einer dekorativen Kunetetoffolie beklebt sind. An ihren einander gegenüberliegenden Lägeseiten 21 sind die Paneele 18 mit durchlaufenden Länganuten 22 versehen, in welche Federn 23 eingeschoben sind, die ebenao wie die Panoelo 18 aus Asbestsilicat-Streifen bestshen und die eine größere Breite b haben als die beiden einender zugokehrten Nuten 22 benachbarter Paneele 18. Auf der Oberseite 24 der Federn 23 sind T-förmige Blechprofilleisten 25 der Tragvorrichtung 17 mit Schrauben 26 befestigt. Die ßchraubenköpfe 27 werden von einer Beschichtung 28 oder einer Abdeckung 29 abgedeckt, die an der Unterseite 30 der Federn 23 angeordnet ist.The false ceiling 16 consists of a plurality of parallel, non-flammable panels 18 made of asbestailicate, which are closely spaced next to one another at a distance and which have a wooden veneer or one on their underside and possibly also on the longitudinal sides of the lower fleneche 2o decorative plastic foil are glued. On their opposite lying sides 21, the panels 18 are provided with continuous longitudinal grooves 22 into which springs 23 are inserted, which, like the panel 18, are made of asbestos silicate strips and have a greater width b than the two facing grooves 22 of adjacent panels 18. T-shaped sheet metal profile strips 25 of the carrying device 17 are fastened on the upper side 24 of the springs 23 with screws 26. The ß screw heads 27 are covered by a coating 28 or a cover 29 which is arranged on the underside 30 of the springs 23.

Bei den in Fig. 7 dargestellten Ausführungsbeispiel haben die Federn 23 im Querschnitt ein T-Profil, dessen Flansche 31 in die Kuten 22 der Profile eingreifen und deren Steg 33 zwischen den oberen Flanachen 34 der Paneele 18 liegt. Die Dicke d der Ftansche 31 der Feder 23 in Fig. 7 ist etwas kleiner als die Dicke D der Länganuten 22. Hierdurch bleiben zwischen der Unterseite 30 der Feder 23 und den Innerflächen 35 der unteren Flansche 20 der Paneele 18 schmele Schlitze frei, in die ein Streifen 36 aus nicht brannbarem Schaumstoff eingeschoben ist, der die Schraubenköpfe 27..der Befestigungsschrauben 26 abdeckt.In the embodiment shown in FIG. 7, the springs 23 have a T-profile in cross section, the flanges 31 of which engage in the grooves 22 of the profiles and the web 33 of which lies between the upper flanges 34 of the panels 18. The thickness d of the flanges 31 of the spring 23 in FIG. 7 is somewhat smaller than the thickness D of the longitudinal grooves 22. This leaves between the underside 30 of the spring 23 and the inner surfaces 35 of the lower flanges 20 of the panels 18 narrow slots into which a strip 36 of non-combustible foam is inserted, which covers the screw heads 27.. of the fastening screws 26.
