Description

Zum Feuerschutz von Türen, Klappen, Gehäusen oder Möbeln sind die verschiedensten Systeme bzw. Elementaufbauten bekannt. Bei diesen Systemen geht es darum, Unbrennbarkeit der Gegenstände mit einer möglichst langen Feuerwiderstandszeit bei möglichst befriedigenden mechanischen Eigenschaften der Gegenstände zu kombinieren.A wide variety of systems and element structures are known for fire protection of doors, flaps, housings or furniture. The aim of these systems is to combine the non-combustibility of the objects with the longest possible fire resistance time with the most satisfactory mechanical properties of the objects.

Die bekannten und oft sehr aufwendig konstruierten Systeme versagen im Brandfall nicht wegen zu geringer Isolierung, sondern manchmal durch Verzug der Gesamtkonstruktion und durch Rissebildung bzw. Verwerfungen der Isolierschicht. Durch die im Brandfall entstandenen Fugen, Ritzen und Isolierschwachstellen können nun das Feuer bzw. die brennbaren Gase ungehindert passieren, d.h. die gewünschte Feuerwiderstandsdauer wird nicht erreicht. Eine solche Rissebildung bzw. Verzug läßt sich nur sehr ungenau quantitativ vorhersehen, da in solche Überlegungen z.B. die Fertigungstoleranzen und die Art der Feuerbelastung (flächig, punktuell) eingehen. Dieser Umstand macht z. B. bei Feuerschutztüren einen hohen technischen Aufwand erforderlich, um die garantierte Feuerwiderstandsdauer zu erbringen.The known and often very complex systems fail not in the event of a fire due to insufficient insulation, but sometimes due to warping of the overall construction and the formation of cracks or warpage of the insulating layer. Due to the joints, cracks and insulation weak points created in the event of a fire, the fire or the combustible gases can now pass unhindered, ie the desired fire resistance duration is not achieved. Such a crack formation or delay can only be predicted quantitatively very imprecisely, since in such considerations, for example, the Manufacturing tolerances and the type of fire exposure (flat, selective). This fact makes z. B. with fire doors a high technical effort required to provide the guaranteed fire resistance.

Aufgabe der vorliegenden Erfindung war es daher, ein Verfahren schaffen, mit dem ein feuerbeständiges Bauteil, was unbrennbar ist, eine hohe Feuerwiderstandsdauer besitzt und konstruktiv einsetzbar ist, hergestellt werden kann. Dieses Element soll selbständig thermisch gesteuert im Brandfall die auftretenden Schwachstellen ausgleichen und beheben.The object of the present invention was therefore to create a method with which a fire-resistant component which is non-flammable, has a high fire resistance duration and can be used in construction can be produced. In the event of a fire, this element is to be independently thermally controlled to compensate and remedy the weak points that arise.

Die Aufgabe wird dadurch gelöst, daß ein blähfähiger feuerbeständiger Brandschutzkitt mit einem Formteil aus Magnesiumoxichloridschaum unlösbar verbunden wird.The object is achieved in that an expandable fire-resistant fire protection cement is permanently connected to a molded part made of magnesium oxychloride foam.

Gegenstand der vorliegenden Erfindung ist daher ein Verfahren zur Herstellung feuerbeständiger Bauteile, bei dem auf eine Magnesiumoxidchloridschaumplatte Brandschutzkitt an den Verzugs- bzw. Riß-gefährdeten Stellen aufgetragen wird.The present invention therefore relates to a method for producing fire-resistant components, in which fire protection putty is applied to the points at risk of warping or cracking on a magnesium oxide chloride foam sheet.

Es wurde überraschenderweise gefunden, daß derartaufgebaute Bauteile auch bei Rissebildung bzw. Verzug der Gesamtkonstruktion ihre geplante Feuerwiderstandsdauer erbringen. Im Brandfall tritt an jeder eventuell auftretenden Riß- bzw. Isolierschwachstelle der Bauteile die Wärme durch und aktiviert den Brandschutzkitt,It has surprisingly been found that the components constructed in this way also achieve their planned fire resistance duration if the overall structure is cracked or warped. In the event of a fire, the heat passes through at any possible crack or insulation weak point in the components and activates the fire protection cement,

der nun seinerseits die Schwachstelle durch Aufblähen ausfüllt und damit thermisch isoliert. Es ist hierbei unerheblich, ob dieser Brandschutzkitt die Isolierplatte ganz umhüllt, sich punktuell oder flächig zwischen zwei Isolierplatten befindet oder ob diese nur einseitig mit Brandschutzkitt beschichtet sind. Es muß jedoch sichergestellt sein, daß an Stellen der zu erwartenden größten Deformation bzw. Rißbildung genügend Kittmasse zur Verfügung steht. So werden bei feuerbeständigen bzw. feuerhemmenden Türen z.B. im Schloßbereich und im Bereich der Zuhaltevorrichtungen größere Kittmengen aufgetragen, um im Brandfall das gesamte Schließwerk abzudichten.which in turn now fills the weak point by swelling and thus thermally insulates it. It is irrelevant whether this fire protection putty completely surrounds the insulating plate, whether it is punctiform or flat between two insulating plates or whether these are only coated on one side with fire protection putty. However, it must be ensured that sufficient putty is available at the places where the greatest deformation or crack formation is to be expected. For example, fire-resistant or fire-retardant doors larger amounts of cement were applied in the lock area and in the area of the locking devices in order to seal the entire locking system in the event of a fire.

Die anorganische Magnesiumoxichloridschaumplatte erbringt nicht nur die gewünschte Feuerwiderstandsdauer, sondern besitzt auch die notwendige Festigkeit, um das Bauteil als Verbundelement bzw. Kern auch konstruktiv einsetzen zu können. Vorzugsweise enthält der Magnesiumoxichloridschaum feinteilige Glasfaser, die auf den Schaum sogar noch verfestigend wirkt und im Brandfall einer Rissebildung entgegen wirkt.The inorganic magnesium oxychloride foam panel not only provides the desired fire resistance, but also has the necessary strength to be able to use the component as a composite element or core in the construction. The magnesium oxychloride foam preferably contains finely divided glass fibers which even have a strengthening effect on the foam and counteracts the formation of cracks in the event of a fire.

Der Magnesiumoxichloridschaum wird in bekannter Weise durch Vermischen von Magnesiumchlorid, Magnesiumoxid bzw. gebranntem Magnesit, Wasser, Netzmitteln und gegebenenfalls Zusatzmitteln hergestellt und dieses Gemisch durch Verschäumer, z. B. Wasserstoffperoxid und gegebenenfalls Katalysatoren verschäumt.The magnesium oxychloride foam is produced in a known manner by mixing magnesium chloride, magnesium oxide or fired magnesite, water, wetting agents and optionally additives this mixture by foaming agents, e.g. B. foamed hydrogen peroxide and optionally catalysts.

Als Brandschutzkitt werden bevorzugt schäumbare Formmassen auf der Basis von Intumeszensmitteln eingesetzt, die einen Gehalt an Füllstoffen aufweisen, wobei die Füllstoffe kugelig sind bzw. nahezu kugelige Gestalt besitzen und aus einem anorganischen Material bestehen. Unter Intumeszensmitteln werden solche Stoffe verstanden, die bei höheren Temperaturen Blasen bilden bzw. aufschäumen und einen vielzelligen isolierenden Schaum erzeugen.Foamable molding compositions based on intumescent agents which contain fillers are preferably used as fire protection putty, the fillers being spherical or almost spherical in shape and consisting of an inorganic material. Intumescent agents are understood to mean those substances which form or foam at higher temperatures and produce a multicellular insulating foam.

Zur besseren Verankerung des Brandschutzkitts auf der Oberfläche der Magnesiumoxichloridschaumplatte kann diese mit Zapfen oder Noppen versehen sein, in die der Brandschutzkitt eingelegt oder eingepreßt wird. Die Brandschutzkittschichten oder Stellen können jedoch auch vorgegeben werden, gegebenenfalls in Verbindung mit einem weiteren Konstruktionselement in das der Magnesiumoxichloridschaum dann in flüssigem Zustand als Kern bzw. Schicht oder Platte eingespachtelt bzw. eingespritzt wird.To better anchor the fire protection putty on the surface of the magnesium oxychloride foam plate, it can be provided with pins or knobs into which the fire protection putty is inserted or pressed. However, the fire protection kit layers or locations can also be specified, if necessary in conjunction with a further construction element into which the magnesium oxychloride foam is then filled or injected in the liquid state as a core or layer or plate.

Nach dieser Erfindung ist es möglich, die Rahmenkonstruktion der vorstehend beschriebenen Bauteile, wie Türen, Klappen, Gehäuse, Wände usw. an deren brandkritischen Stellen so zu präparieren, daß im Brandfall bei Rissebildung oder Verzug der Brandschutzkitt austreten kann und die gesamte Konstruktion nach den Prinzipien des Brandschutzes hermetisch abgeschlossen wird.According to this invention, it is possible to prepare the frame construction of the components described above, such as doors, flaps, housings, walls, etc. at their fire-critical points so that in the event of a fire, cracking or warping can result in the fire protection cement and the entire construction according to the principles fire protection is hermetically sealed.
