Description

Die Erfindung betrifft ein Gebäudeelement in brandgeschützer Ausführung, insbesondere in Form einer Brandschutztür, eines Brandschutzfensters oder einer Brandschutzwand, mit einem Rahmen aus einer metallischen Außenschale, einer Innenschale sowie einer Mittelschale, wobei die Außenschale und die Innenschale jeweils über Isolierelemente mit der Mittelschale verbunden sind, sowie mit einem im Rahmen vorzugsweise zwischen der Außenschale und der Innenschale dichtend gehaltenen Ausfachungselement, wobei die Außenschale, die Mittelschale sowie die Innenschale über einen brandresistenten Schalenverbinder miteinander verbunden sind, der form- und/oder kraftschlüssig an jeder der Schalen angeschlossen ist.The invention relates to a building element in fire-protected design, in particular in the form of a fire door, a fire protection window or a fire wall, with a frame of a metallic outer shell, an inner shell and a middle shell, wherein the outer shell and the inner shell are respectively connected via insulating with the center shell, and with a preferably in the frame between the outer shell and the inner shell sealing infill element, wherein the outer shell, the center shell and the inner shell are connected to each other via a fire-resistant shell connector which is positively and / or non-positively connected to each of the shells.

Aus der AT-B-412 494 ist ein Flügel- und/oder Stockrahmen aus Profilstäben für Fenster, Türen, Fassaden, Glasdächer od. dgl. bekannt, wobei mindestens ein Profilstab aus mindestens zwei Teilprofilen besteht, die über eine thermische Trennung miteinander verbunden sind. Wenigstens ein Teilprofil ist ein aus Metall, insbesondere aus Aluminium, gefertigtes Hohlprofil. Auf der der Glasscheibe zugewandten Seite des Profilstabes ist ein Brandschutzstreifen aus unter Temperaturbelastung aufblähendem Material angeordnet, der über eine Profilhaltefeder fixiert ist, wobei die Profilhaltefeder aus einem Material mit einem Schmelzpunkt, der über dem der Teilprofile liegt, besteht.From the AT-B-412 494 is a wing and / or floor frame made of profiled bars for windows, doors, facades, glass roofs od. The like. Known, wherein at least one profile bar consists of at least two sub-profiles, which are connected to each other via a thermal separation. At least one partial profile is a hollow profile made of metal, in particular aluminum. On the side facing the glass sheet of the profile bar, a fire protection strip is arranged from under temperature load aufblähendem material which is fixed by a profile holding spring, wherein the profile holding spring made of a material having a melting point, which is above the sub-profiles consists.

Bei derartigen Gebäudeelementen werden die metallischen Rahmen vorzugsweise aus Aluminium gefertigt, da sich dieses Material in unterschiedlichsten Profilstrukturen auf relativ einfachem Wege durch Strangpreßverfahren herstellen läßt.In such building elements, the metallic frames are preferably made of aluminum, since this material can be produced in a wide variety of profile structures in a relatively simple way by extrusion.

Allerdings ist zu beachten, dass Aluminium einen relativ niedrigen Schmelzpunkt besitzt, so dass für den Brandschutz besondere Maßnahmen erforderlich sind. Hierzu gehört insbesondere auch, derartige Gebäudeelemente in wärmegedämmter Bauweise auszuführen, obwohl sie meist nur im Innenbereich Verwendung finden. Dabei ist jedoch weiter zu beachten, dass die wärmedämmenden Maßnahmen, also der Einsatz üblicherweise aus Kunststoff bestehender Isolierstege, zu einem vorzeitigen Versagen der Brandschutzmaßnahme führen kann, wenn die die Schalen zusammenhaltenden Isolierstege zerstört werden.However, it should be noted that aluminum has a relatively low melting point, so that special measures are required for fire protection. This includes, in particular, to perform such building elements in thermally insulated construction, although they are usually used only indoors. However, it should also be noted that the heat-insulating measures, so the use of plastic usually existing insulating bars, can lead to premature failure of the fire protection measure when the shells holding together insulating bars are destroyed.

Der Erfindung liegt die Aufgabe zugrunde, ein Gebäudeelement der eingangs genannten Art so zu verbessern, dass die Stabilität eines aus drei Schalen bestehenden Gebäudeelements auch länger andauernden Brandeinwirkungen widersteht, indem für einer Verringerung der Wärmeleitung gesorgt wird.The invention has for its object to improve a building element of the type mentioned so that the stability of a three-shell building element also withstands prolonged fire, by providing a reduction in heat conduction.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die Isolierelemente als Stege ausgebildet sind; dass der Schalenverbinder aus Flachmaterial gebildet ist, wobei zur formschlüssigen Verbindung mit der Mittelschale eine sickenförmige Vertiefung eingeprägt ist; dass die sickenförmige Vertiefung mittig mit einer Freistanzung versehen ist und daß vom einen Rand der Freistanzung ein Befestigungssteg über die sickenförmige Vertiefung vorsteht.This object is achieved according to the invention in that the insulating elements are designed as webs; that the shell connector is formed from flat material, wherein a bead-shaped depression is embossed for the positive connection with the middle shell; that the bead-shaped depression is provided centrally with a free punching and that protrudes from one edge of the free punching a fastening web on the bead-shaped depression.

Der Vorteil einer solchen Anordnung ist zunächst, dass der Schalenverbinder aus hitzebeständigem Material, insbesondere aus Stahl, bestehen kann, so dass die einzelnen Schalen des Gebäudeelements selbst dann noch in ihrer vorgesehenen, auf Abstand gehaltenen Lage verbleiben, wenn die Isolierstege bereits weggeschmolzen sind. Da die Schalenverbinder als solche keine allzugroße Materialstärke benötigen, bleibt ihr Anteil an Wärmeleitung im Brandfall von der Außen- zur Innenschale zwar klein; der Vorteil besteht jedoch darin, daß die Freistanzung einerseits zu einer weiteren Verringerung der Wärmeleitung über den Schalenverbinder führt, während der Befestiungssteg zum Anschluss weiterer Teile dienen kann, worauf noch einzugehen ist.The advantage of such an arrangement is first that the shell connector made of heat-resistant material, in particular steel, may exist, so that the individual shells of the building element even remain in their intended, kept at a distance position when the insulating bars are already melted away. Since the shell connectors as such do not require too much material thickness, their share of heat conduction in case of fire from the outer to the inner shell remains small; the advantage, however, is that the free punching on the one hand leads to a further reduction of the heat conduction through the shell connector, while the fastening web can serve to connect other parts, which will be discussed later.

In bevorzugter Ausführungsform der Erfindung ist dabei vorgesehen, dass der Schalenverbinder an seinem zur Innenschale weisenden Rand mit einem eine senkrecht zum Rahmen nach innen vorstehende Profilleiste umgreifenden, hakenförmig ausgebildeten Falz versehen ist. Durch dieses Konstruktionsmerkmal kann der Schalenverbinder an der Innenschale einfach eingehängt werden und bedarf dort keiner weiteren Befestigungsmaßnahmen.In a preferred embodiment of the invention it is provided that the shell connector is provided at its facing the inner shell edge with a perpendicular to the frame inwardly projecting profile strip embracing, hook-shaped fold. By this design feature, the shell connector can be easily hung on the inner shell and there requires no further attachment measures.

Ferner ist im Rahmen der Erfindung vorgesehen, dass der Schalenverbinder an seinem zur Außenschale weisenden Rand mit wenigstens einem zum Ausfachungselement weisenden Haltesteg sowie mit einer Anschlußlasche zur Befestigung des Schalenverbinders an der Außenschale versehen ist. Dies lässt sich in besonders einfacher Weise dadurch erreichen, dass die Anschlußlasche mittig zwischen den Haltestegen angeordnet und aus diesen freigeschnitten ist. Damit kann im Ergebnis der Schalenverbinder in besonders einfacher Weise aus Flachmaterial durch Freistanzungen und entsprechende Abwinklungen hergestellt werden.It is further provided in the context of the invention that the shell connector is provided at its edge facing the outer shell with at least one pointing to Ausfachungselement retaining web and with a connecting strap for fastening the shell connector to the outer shell. This can be achieved in a particularly simple manner in that the connecting plate is arranged centrally between the holding webs and cut free from them. As a result, the shell connector can be produced in a particularly simple manner from flat material by free-punching and corresponding bends.

Die Anschlußlasche ist dabei zweckmäßigerweise mit einer Bohrung für eine Befestigungsschraube versehen, so dass sich der Schalenverbinder an der Außenschale anschrauben lässt.The terminal lug is expediently provided with a bore for a fastening screw, so that the shell connector can be screwed to the outer shell.

Als weitere Brandschutzmaßnahme ist im Rahmen der Erfindung vorgesehen, dass der der Aufnahme des Ausfachungselements dienende Falz mit einem Aufschäum-Streifen belegt ist, der den Schalenverbinder überdeckt.As a further fire protection measure is provided in the context of the invention that the receiving of the infill element serving fold is covered with a foaming strip, which covers the shell connector.

Weiter ist zur innenseitigen Befestigung des Ausfachungselements ein Winkelprofil vorgesehen, das am Befestigungssteg angeschlossen ist. Dies kann beispielsweise durch eine einfache Schaubverbindung erfolgen.Next, an angle profile is provided for the inside fastening of the infilling element, which is connected to the fastening web. This can be done for example by a simple Schaubverbindung.

Als weitere Brandschutzmaßnahme kann noch vorgesehen sein, dass in den von den Isolierstegen gebildeten Kammern Aufschäum-Einlagen angeordnet sind, wodurch die jeweils brandabgewandte Schale vor Hitzeeinwirkung geschützt wird. Schließlich können im Tür- bzw. Fensterfalz, ganz nahe bei der gegenseitigen Abdichtung zweier Rahmen dienender Anschlagdichtungen, profilierte Aufschäumer angebracht sein um einen vorzeitigen Flammdurchschlag zu verhindern.As a further fire protection measure can still be provided that in the chambers formed by the insulating webs foaming deposits are arranged, whereby the respective brand facing shell is protected from the action of heat. Finally, in the door or window fold, very close to the mutual sealing of two frame serving stop seals, profiled frothing be mounted to prevent premature flame penetration.

Das in der Zeichnung nur teilweise dargestellte Gebäudeelement kann beispielsweise eine Brandschutztür, ein Brandschutzfenster oder auch eine Brandschutzwand sein. Bei diesem Gebäudeelement handelt es sich um eine brandgeschützte Ausführung, die dazu als dreischaliges Profil ausgebildet ist, so dass der Rahmen also aus einer Außenschale 1, einer Innenschale 2 sowie einer Mittelschale 3 besteht.The building element only partially shown in the drawing can be, for example, a fire door, a fire protection window or a fire wall. This building element is a fire-protected design, which is designed as a three-shell profile, so that the frame thus consists of an outer shell 1, an inner shell 2 and a middle shell 3.

Um einen auch bei Verwendung von Aluminium ausreichenden Brandschutz zu erreichen, ist der Aufbau der Schalen 1, 2, 3 ähnlich dem von wärmegedämmten Rahmen, das heißt die Außenschale 1 und die Innenschale 2 sind jeweils über Isolierstege 4 mit der Mittelschale 3 verbunden. Im Rahmen selbst, vorzugsweise zwischen der Außenschale 1 und der Innenschale 2, ist ein Ausfachungselement 5 dichtend gehalten, wobei das Ausfachungselement 5 üblicherweise aus Glas besteht.In order to achieve sufficient even when using aluminum fire protection, the structure of the shells 1, 2, 3 is similar to that of thermally insulated frame, that is, the outer shell 1 and the inner shell 2 are respectively connected via insulating bars 4 with the middle shell 3. In the frame itself, preferably between the outer shell 1 and the inner shell 2, a infill element 5 is held sealingly, wherein the infill element 5 is usually made of glass.

Um im Falle einer Brandeinwirkung sicherzustellen, dass die drei Schalen 1, 2, 3 des Gebäudeelements selbst dann in der vorgesehenen Weise auf Abstand gehalten werden, wenn die Isolierstege 4 geschmolzen bzw. zerstört sind, ist ein brandresistenter Schalenverbinder 6 vorgesehen, der die Außenschale 1, die Mittelschale 3 sowie die Innenschale 2 miteinander verbindet und dazu form- und/oder kraftschlüssig an jeder Schale 1, 2, 3 angeschlossen ist.In order to ensure in case of fire, that the three shells 1, 2, 3 of the building element are held even in the intended manner at a distance when the insulating bars 4 are melted or destroyed, a fire-resistant shell connector 6 is provided, the outer shell. 1 , the middle shell 3 and the inner shell 2 connects to each other and is positively and / or non-positively connected to each shell 1, 2, 3.

Im einzelnen ist der Schalenverbinder 6 aus Flachmaterial gebildet, wobei zur formschlüssigen Verbindung mit der Mittelschale 3 eine sickenförmige Vertiefung 7 eingeprägt ist, die zwischen zwei an der Mittelschale 3 vorstehende Stege 8 greift.In detail, the shell connector 6 is formed from flat material, wherein for the positive connection with the middle shell 3 a bead-shaped recess 7 is embossed, which engages between two protruding on the middle shell 3 webs 8.

Wie sich aus der Figur 3 ersehen lässt, ist die sickenförmige Vertiefung 7 mittig mit einer Freistanzung 9 versehen, wobei vom einen Rand der Freistanzung ein Befestigungssteg 10 über die sickenförmige Vertiefung 7 vorsteht.As is clear from the FIG. 3 can be seen, the bead-shaped recess 7 is provided centrally with a free punching 9, wherein from one edge of the free punching a fastening web 10 projects beyond the bead-shaped recess 7.

An seinem zur Innenschale 2 weisenden Rand ist der Schalenverbinder 6 mit einem hakenförmig ausgebildeten Falz 11 versehen, der eine senkrecht zum Rahmen nach innen vorstehende Profilleiste 12 der Innenschale 2 umgreift. Dies ermöglicht eine besonders einfache Montage des Schalenverbinders 6, da er an die Innenschale 2 lediglich eingehängt werden muss.At its facing the inner shell 2 edge of the shell connector 6 is provided with a hook-shaped fold 11 which surrounds a perpendicular to the frame inwardly projecting profile strip 12 of the inner shell 2. This allows a particularly simple assembly of the shell connector 6, since it only needs to be hooked to the inner shell 2.

An seinem zur Außenschale 1 weisenden Rand ist der Schalenverbinder 6 mit zwei zum Ausfachungselement 5 weisenden Haltestegen 13 versehen; zwischen beiden Haltestegen 13 ist eine Anschlußlasche 14 vorgesehen, die zur Befestigung des Schalenverbinders 6 an der Außenschale 1 dient. Diese Anschlußlasche 14 ist dabei mittig zwischen den Haltestegen 13 angeordnet und von diesen lediglich freigeschnitten. Dies erlaubt eine einfache Herstellung des Schalenverbinders 6 aus Flachmaterial.At its edge facing the outer shell 1, the shell connector 6 is provided with two retaining webs 13 pointing to the infill element 5; between two retaining webs 13, a connecting lug 14 is provided, which serves for fastening of the shell connector 6 to the outer shell 1. This connecting plate 14 is arranged centrally between the retaining webs 13 and only cut free of these. This allows a simple production of the shell connector 6 made of flat material.

Die Anschlußlasche 14 ist mit einer Bohrung versehen, durch die der Schalenverbinder 6 mittels einer Befestigungsschraube 15 an der Außenschale 1 angeschraubt werden kann.The connecting lug 14 is provided with a bore through which the shell connector 6 can be screwed by means of a fastening screw 15 to the outer shell 1.

Wie sich insbesondere aus der Figur 1 ersehen lässt, ist der der Aufnahme des Ausfachungselement 5 dienende Falz mit einem Aufschäum-Streifen 16 belegt, der den Schalenverbindung 6 überdeckt.As can be seen in particular from the FIG. 1 can be seen, the recording of the infill element 5 serving fold is occupied by a frothing strip 16, the Shell connection 6 covered.

Zur innenseitigen Befestigung des Ausfachungselementes 5 ist ein Winkelprofil 17 vorgesehen, das am Befestigungssteg 6 mittels einer Schraube 18 angeschlossen ist.For internal fastening of the infill element 5, an angle profile 17 is provided which is connected to the fastening web 6 by means of a screw 18.

Im übrigen können als weitere dem Brandschutz dienende Maßnahmen Aufschäum-Einlagen 19 in den von den Isolierstegen 4 gebildeten Kammern sowie profilierte Aufschäumer 20 in dafür vorgesehenen Aufnahmezonen im Nahbereich von Anschlagdichtungen 21 angeordnet sein, die der gegenseitigen Abdichtung von Rahmen dienen.Incidentally, as further measures serving fire protection Aufschäum deposits 19 in the chambers formed by the insulating 4 and profiled skimmer 20 may be arranged in designated receiving zones in the vicinity of stop seals 21, which serve the mutual sealing of frame.
