Description

Feuerhemmende bzw. feuerfeste Türen mit den verschiedensten Einlagen, wie z. B. Mineralwolle, Gipskarton-Platten oder asbesthaltigen Platten sind bekannt, z.B. aus der Zulassung vom IfBT, Z 6.13 - 117. Diese Türeinlagen werden in einem separaten Arbeitsgang in zum Teil aufwendigen Verfahren hergestellt und dann in weiteren Arbeitsgängen zugeschnitten und in die Rahmenkonstruktion des Türblattes eingefügtFire-retardant or fireproof doors with a variety of inserts, such as. Mineral wool, plasterboard or asbestos-containing boards are known, e.g. from the approval of the IfBT, Z 6.13 - 117. These door inserts are manufactured in a separate work step in partly complex procedures and then cut in further work steps and inserted into the frame construction of the door leaf

Diese Türeinlagen besitzen jedoch keine tragende Funktion im Türaufbau, die Türrahmen- bzw. Türblattkonstruktion muß deshalb sehr stabil ausgeführt sein. Die Blechstärken der Rahmen bzw. Türblätter sind daher erheblich, im Brandfall treten deshalb sehr starke Verzugserscheinüngen auf. Diese Verzugserscheinungen sind so groß, daß im Brandfall teilweise die Tür sich derart verziehen kann, daß das Feuer durchschlägt. Ferner muß bei einigen dieser Türkonstruktionen die Einlage zusätzlich gestützt und fixiert werden.However, these door inserts have no load-bearing function in the door structure, the door frame or door leaf construction must therefore be made very stable. The sheet thicknesses of the frames or door leaves are therefore considerable, so there are very strong signs of warping in the event of a fire. These signs of delay are so great that in the event of a fire, the door can sometimes warp in such a way that the fire breaks through. Furthermore, with some of these door constructions, the insert must be additionally supported and fixed.

Aufgabe der vorliegenden Erfindung war es daher, ein Verfahren zur Herstellung eines feuerfesten Türkonstruktionselementes zu schaffen, mit dem das Türblatt mit geringeren materiellen Mitteln serienmäßig in der gewünschten Form und Ausführung hergestellt werden kann und die Anforderungen bezüglich der geforderten Feuerwiderstandszeiten erfüllt.The object of the present invention was therefore to provide a method for producing a fire-resistant door construction element with which the door leaf can be manufactured in series in the desired shape and design with less material resources and meets the requirements with regard to the required fire resistance times.

Diese Aufgabe wird durch ein Verfahren zur Herstellung eines feuerfesten Türblattes gelöst, das dadurch gekennzeichnet ist, daß man auf einer dünnen Blechhaut eine Mineralfaserschicht aufklebt und anschließend eine Magnesiumoxidchlorid-Schaumschicht aufträgt. Die Mineralfaserschicht kann ein Netz, Gewebe, Gewirke oder auch Matte aus den verschiedensten anorganischen Bestandteilen, z. B. Glaswolle, Steinwolle und/oder Asbestfasern sein. Vorzugsweise wird eine Glasfasermatte mit einem Flächengewicht von ca. 250 g/m2 verwendet.This object is achieved by a method for producing a fire-resistant door leaf, which is characterized in that a mineral fiber layer is glued onto a thin sheet metal skin and then a magnesium oxide chloride foam layer is applied. The mineral fiber layer can be a mesh, woven fabric, knitted fabric or mat made from a wide variety of inorganic constituents, e.g. B. glass wool, rock wool and / or asbestos fibers. A glass fiber mat with a weight per unit area of approximately 250 g / m 2 is preferably used.

Als feuerfester Kleber wird vorzugsweise eine Wasserglasschicht, in welche die Glasfasermatte eingebetet wird, verwendet. Die Klebemenge soll so aufgetragen werden, daß die Glasfasermatte nicht durchgetränkt ist, sondern noch Mattenteile trocken bleiben. In diesen noch trockenen Faseranteilen verankert sich der aufgebrachte Magnesiumoxichloridschaum.A water glass layer in which the glass fiber mat is embedded is preferably used as the refractory adhesive. The amount of adhesive should be applied so that the glass fiber mat is not soaked, but mat parts remain dry. The magnesium oxychloride foam applied is anchored in these still dry fiber parts.

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

Durch die Zwischenschicht wird die Blechverkleidung so gut mit der Magnesiumoxichloridschaumschicht verbunden, daß eine erhebliche Verringerung der Blechstärke, z.B. bis auf dünne Folienstärken möglich ist, und auf zusätzliche Aussteifungswinkel und Verschraubungen sowie besondere Profilierungen verzichtet werden kann.By means of the intermediate layer, the sheet metal cladding is so well connected to the magnesium oxychloride foam layer that a considerable reduction in the sheet thickness, e.g. down to thin film thickness is possible, and additional bracing angles and screw connections as well as special profiles can be dispensed with.

Die Verringerung der Blechstärke und Vereinfachung der Aussteifung bewirkt bei einseitiger thermischer Belastung im Brandfall geringe Verzugserscheinungen der gesamten Türkonstruktion, was widerum einfachere Zuhaltungen und Beschläge ermöglicht. Besitzt die Blechverkleidung nur Folienstärke, so schmilzt diese im Brandfalle weg und es treten überhaupt keine Verzugserscheinungen auf. Dies kann z. B. auch bewußt hervorgerufen werden, indem z.B. die Blechhaut aus Aluminium bzw. anderen Leichtmetallen, die brennbar bzw. leicht schmelzbar sind, besteht.The reduction in the sheet thickness and simplification of the stiffening causes little distortion of the entire door structure in the event of fire in the event of a one-sided thermal load, which in turn enables simpler tumblers and fittings. If the sheet metal cladding has only film thickness, it melts away in the event of a fire and there are no signs of distortion at all. This can e.g. B. are also deliberately caused by e.g. the sheet metal skin consists of aluminum or other light metals that are combustible or easily meltable.

In einer Verfahrensvariante werden zwei Türdeckschichten mit dem vorstehend beschriebenen Aufbau zusammengelegt und miteinander verbunden, so daß ein Brandschutz nach beiden Seiten möglich ist. In diesem Fall kann jedoch auch nur eine Türdeckschicht entweder mit oder ohne eine Wasserglasschicht auf eine vorstehend beschriebenen Türdeckschicht aufgebracht werden. Vorzugsweise wird in den Magnesiumoxidchloridschaum feinteilige Glasfaser, eingebracht, die auf den Schaum soga verfestigend wirkt und im Brandfall eine Rissebildung verhindert.In a process variant, two door cover layers with the structure described above are put together and connected to one another, so that fire protection is possible on both sides. In this case, however, only one door cover layer can be applied to a door cover layer described above either with or without a water glass layer. Preferably, finely divided glass fiber is introduced into the magnesium oxide chloride foam, which has a so-called strengthening effect on the foam and prevents crack formation in the event of a fire.

Für den Brandschutz ist es unerheblich, welche Form die Tür aufweist, die Magnesiumoxichloridschaumschicht soll jedoch eine genügende Dicke aufweisen, um im Brandfalle die erforderliche Feuerwiderstandszeit aufzuweisen.The shape of the door is irrelevant for fire protection, but the magnesium oxychloride foam layer should be of sufficient thickness to have the required fire resistance time in the event of a fire.

Die vorliegende Erfindung soll durch die folgenden Beispiele bzw. Figuren noch näher erläutert werden:The present invention is illustrated by the following examples and figures:

Beispiel 1example 1

An der Tür-Rahmenkonstruktion (1) ist ein Türblech (2) bereits befestigt. Ebenso sind alle Beschläge und Zuhaltungen (3) montiert. Die Innenseite dieser Türausführung (1, 2, 3) und das Deckblech (4) werden mit Kleber (5) bestrichen. In diese Kleberschicht wird die Glasmatte (6) eingelegt. Der Rand (7) bleibt frei von Kleber und Glasmatte. Die Rahmenkonstruktion (1) wird mit flüssigem Magnesiumoxichloridschaum (8) ausgefüllt. Es empfiehlt sich ebenfalls die Glasmatte (6) auf dem Deckblech (4) mit Magnesiumoxichloridschaum zu imprägnieren. Nun wird das Deckblech (4) auf die Rahmenkonstruktion (1) gelegt und im Randbereich (7) durch Schrauben, Nieten oder Schweißen (9) verbunden. Der flüssige Magnesiumoxichloridschaum in der Rahmenkonstruktion (1) und der auf dem Deckblech (4) verbinden sich und bilden nach dem Aushärten eine Einheit.A door panel (2) is already attached to the door frame construction (1). All fittings and tumblers (3) are also mounted. The inside of this door version (1, 2, 3) and the cover plate (4) are coated with adhesive (5). The glass mat (6) is placed in this adhesive layer. The edge (7) remains free of glue and glass mat. The frame structure (1) is filled with liquid magnesium oxychloride foam (8). It is also advisable to impregnate the glass mat (6) on the cover plate (4) with magnesium oxychloride foam. Now the cover plate (4) is placed on the frame structure (1) and connected in the edge area (7) by screws, rivets or welding (9). The liquid magnesium oxychloride foam in the frame construction (1) and that on the cover plate (4) combine and form a unit after curing.

Beispiel 2Example 2

Wie in Beispiel 1 wird die Rahmenkonstruktion (1) und das Deckblech (4) mit Kleber (5) und Glasmatten (6) versehen. Ohne Magnesiumoxichloridschaumfüllung wird nun das Bauteil fertig montiert (verschraubt, genietet, verschweißt) (9). Durch einen Anguß (12) wird der flüssige Magnesiumschaum (8) durch eine Pumpe bzw. durch ein Misch- und Dosieraggregat in den Tür-Hohlraum (10) gefördert.As in Example 1, the frame structure (1) and the cover plate (4) are provided with adhesive (5) and glass mats (6). Without the magnesium oxychloride foam filling, the component is now fully assembled (screwed, riveted, welded) (9). The liquid magnesium foam (8) is conveyed into the door cavity (10) by a sprue (12) by a pump or by a mixing and metering unit.

Beispiel 3Example 3

Wie in den Beispielen 1 und 2 wird die Rahmenkonstruktion (l/2) und das Deckblech (4) mit Kleber (5) und Glasmatte beschichtet. In den Türhohlraum legt man nun eine fertig zugeschnittene Magnesiumoxichloridschaumplatte oder eine Magnesiumoxichloridschaum-Verbundplatte, die mit Wasserglas oder Magnesiumoxichlorid (13) bestrichen ist, ein. Diese Konstruktion wird wie im Beispiel 1 durch Auflegen des Deckblechs (4) verschlossen und mit dem Rahmenprofil (1) verschraubt, vernietet oder verschweißt.As in Examples 1 and 2, the frame structure (1/2) and the cover plate (4) are coated with adhesive (5) and glass mat. Now place a completely cut magnesium oxychloride foam plate or a magnesium oxychloride foam composite plate coated with water glass or magnesium oxychloride (13) into the door cavity. This construction is closed as in example 1 by placing the cover plate (4) and screwed, riveted or welded to the frame profile (1).
