Abstract

The door case profile is provided with a groove (5) which receives a sealing strip (6) and with a groove (9) which receives a fireproof strip (10). In order to ensure, with a case, produced from such a case profile (2), in conjunction with a door leaf (1) which is designed in correspondingly fire-resistant manner, that a fire remains restricted to the room in which the fire started, there is provided, in at least one part, of the profile leg (13), which is not covered by the door leaf (1), a further groove (14) into which there is arranged a strip (15) which consists of a material with low thermal conductivity.

Description

Die Erfindung betrifft ein Türzargenprofil, insbesondere für eine Feuerschutztür. Das Türzargenprofil ist mit einer ersten, eine Brandschutzleiste aufnehmenden Nut versehen. Diese erste Nut ist aus einem Profilschenkel gebildet, der in der Schließstellung eines Türblattes einer Türblattstirnfläche gegenüberliegt. Das Zargenprofil ist weiterhin mit einer zweiten, eine Dichtungsleiste aufnehmenden Nut versehen. Diese zweite Nut ist aus einem Profilschenkel gebildet, der in der Schließstellung des Türblattes einem Türblattrandstreifen gegenüberliegt.The invention relates to a door frame profile, in particular for a fire door. The door frame profile is provided with a first groove receiving a fire protection strip. This first groove is formed from a profile leg which, in the closed position of a door leaf, lies opposite a door leaf end face. The frame profile is also provided with a second groove receiving a sealing strip. This second groove is formed from a profile leg, which is opposite a door leaf edge strip in the closed position of the door leaf.

Ein derartiges Zargenprofil ist aus der DE 37 43 712 C1 bekannt. Bei dem bekannten Zargenprofil besteht die Gefahr, daß im Brandfall Teile des Zargenprofils auf der dem Brandherd zugewandten Türseite einer solchen Hitze ausgesetzt sind, daß aufgrund des Wärmeleitvermögens der Zarge auch Teile des Zargenprofils auf der dem Brandherd abgewandten Türseite entsprechend erhitzt werden. Sind den betreffenden Teilen der Zarge entzündbare Bauteile, wie zum Beispiel Wandverkleidungen aus Holz, Textilien, Kunststoffen und dergleichen, benachbart, so können diese gleichfalls leicht in Brand geraten, wodurch sich der Brand trotz eines an sich ausreichend feuerhemmend ausgebildeten Türblattes leicht auf Räume ausdehnen kann, die ansonsten mit dem Brandherd nicht unmittelbar in Verbindung stehen.Such a frame profile is known from DE 37 43 712 C1. In the known frame profile, there is a risk that in the event of fire, parts of the frame profile on the side of the door facing the source of the fire are exposed to such heat that, due to the thermal conductivity of the frame, parts of the frame profile on the side of the door facing away from the source of the fire are also heated accordingly. If flammable components, such as wall claddings made of wood, textiles, plastics and the like, are adjacent to the relevant parts of the frame, they can also easily catch fire, which means that the fire can easily expand into rooms despite a door leaf that is sufficiently fire-retardant which are otherwise not directly connected to the source of the fire.

Der Erfindung liegt die Aufgabe zugrunde, ein Zargenprofil der eingangs beschriebenen Art so zu verbessern, daß mit einer daraus gefertigten Zarge in Verbindung mit einem entsprechend feuerhemmend ausgebildeten Türblatt sichergestellt werden kann, einen Brand auf den Raum zu begrenzen, in dem der Brandherd entstanden ist.The invention has for its object to improve a frame profile of the type described above so that it can be ensured with a frame made from it in connection with a correspondingly fire-retardant door leaf to limit a fire to the room in which the source of the fire originated.

Zur Lösung dieser Aufgabe wird von einer Türzarge der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die in seinem kennzeichnenden Teil angegebenen Merkmale aufweisen.To achieve this object, a door frame of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in its characterizing part.

Durch die Leiste aus einem Material mit einer geringen Wärmeleitfähigkeit und deren Anordnung in einer dritten Nut, welche sich vorzugsweise über die volle Fläche des vom Türblatt unabgedeckten Teils des betreffenden Profilschenkels erstreckt und von der Leiste ausgefüllt ist, können an diesem Teil des Zargenprofils brennbare Bauteile angrenzen oder sogar diesen Teil des Zargenprofils überlagern, ohne dadurch die Gefahr einer Ausbreitung des Brandes über den vom Brandherd betroffenen Raum befürchten zu müssen.Due to the strip made of a material with a low thermal conductivity and its arrangement in a third groove, which preferably extends over the full area of the part of the profile leg in question that is not covered by the door leaf and is filled by the strip, combustible components can adjoin this part of the frame profile or even overlay this part of the frame profile without fear of the fire spreading over the area affected by the source of the fire.

Durch die dritte Nut erhält das Zargenprofil über seinen Querschnitt eine zusätzlich abgewinkelte Ausbildung, wodurch sein Wärmeleitvermögen reduziert wird. Zudem erhält die Zarge insgesamt eine größere Kontaktfläche mit der Wand, in deren Öffnung sie eingesetzt ist, und kann dadurch schneller eine größere Wärmemenge ableiten. Auch verlängert sich dabei die Wärmeübertragungsstrecke, so daß ein der Wandverkleidung benachbarter Zargenbereich allenfalls erst nach einem längeren Zeitraum die Temperatur der übrigen Zargenbereiche annehmen kann.The third groove gives the frame profile an additional angled design across its cross-section, which reduces its thermal conductivity. In addition, the frame has a larger contact area with the wall in whose opening it is inserted, and can therefore dissipate a larger amount of heat more quickly. The heat transfer path is also lengthened, so that a frame area adjacent to the wall cladding can at most only take on the temperature of the other frame areas after a longer period of time.

Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist mindestens ein vom Türblatt unabgedeckter Teil eines nutfreien Profilschenkels von einer Leiste aus dem Material mit einer geringen Wärmeleitfähigkeit abgedeckt, wobei die Leiste ihrerseits auf der dem Zargenprofil abgewandten Seite mit einem Blechstreifen verkleidet ist.According to a particularly advantageous embodiment of the invention, at least one part of a groove-free profile leg that is not covered by the door leaf is covered by a strip made of the material with a low thermal conductivity, the strip itself being covered with a sheet metal strip on the side facing away from the frame profile.

Durch diese Ausgestaltung werden sämtliche vom Türblatt nicht abgedeckten Teile des Zargenprofils sowohl auf der dem Brandherd zugewandten Seite als auch auf der dem Brandherd abgewandten Seite der Tür einerseits bereits vor einer gefährlichen Hitzeaufnahme und andererseits vor einer nicht minder gefährlichen Hitzeabgabe sehr wirksam geschützt.With this configuration, all parts of the frame profile not covered by the door leaf are very effectively protected both on the side facing the source of the fire and on the side of the door facing away from the source of the fire, on the one hand, from dangerous heat absorption and, on the other hand, from no less dangerous heat emission.

Vorzugsweise ist die Leiste, die eine geringe Wärmeleitfähigkeit aufweist, aus oder unter Verwendung von zementgebundenem Silikat oder Gips oder einem Material mit vergleichbaren Eigenschaften hergestellt.The strip, which has a low thermal conductivity, is preferably produced from or using cement-bonded silicate or gypsum or a material with comparable properties.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Türzargenprofils in einem Querschnitt dargestellt:
Der Randbereich eines Türblattes 1 ist von einer Zarge aus einem Zargenprofil 2 eingefaßt, das aus einem mehrfach abgewinkelten Blech hergestellt ist.In the drawing, an embodiment of the door frame profile according to the invention is shown in a cross section:
The edge region of a door leaf 1 is framed by a frame made of a frame profile 2, which is made from a multi-angled sheet.

Einem Randstreifen einer Ansichtsfläche 3 des Türblattes, die einem potentiellen Brandherd zugewandt ist, liegt ein Schen- kel 4 des Zargenprofils 2 mit einer ersten Nut 5 gegenüber.A limb 4 of the frame profile 2 with a first groove 5 is opposite an edge strip of a visible surface 3 of the door leaf, which faces a potential source of fire.

In der Nut 5 wird eine elastisch verformbare Dichtungsleiste 6 gehalten, an welcher zur Verbesserung der Dichtwirkung eine gegen die Ansichtsfläche 3 des Türblattes 1 unter Spannung anliegende Lippe 7 angeformt ist. Der Stirnseite des Türblattes 1 liegt ein Schenkel 8 des Zargenprofils 2 mit einer zweiten Nut 9 gegenüber. In der Nut 9 wird eine konventionell ausgebildete Brandschutzleiste 10 gehalten, die aus unter Hitzeeinwirkung aufschäumendem Material besteht und im Brandfall einen Spalt 11 zwischen dem Türblatt 1 und dem Zargenprofil 2 abdichten soll.An elastically deformable sealing strip 6 is held in the groove 5, on which a lip 7, which bears against the face surface 3 of the door leaf 1 under tension, is formed to improve the sealing effect. The end face of the door leaf 1 is opposite a leg 8 of the frame profile 2 with a second groove 9. In the groove 9, a conventionally designed fire protection strip 10 is held, which consists of material foaming under the influence of heat and is intended to seal a gap 11 between the door leaf 1 and the frame profile 2 in the event of a fire.

Einem Falz 12 des Türblattes 1 liegt ein Schenkel 13 des Zargenprofils 2 gegenüber, wobei der vom Falz 12 nicht abgedeckte Teil des Schenkels 13 eine dritte Nut 14 bildet. In der Nut 14 ist eine Leiste 15 aus einem Material mit einer geringen Wärmeleitfähigkeit, wie zementgebundenes Silikat, angeordnet und deckt auf diese Weise auf der betreffenden Seite des Türblatts 1 im wesentlichen das Zargenprofil 2 ab, soweit dieses nicht durch das Türblatt 1 abgedeckt ist.A fold 13 of the door leaf 1 is opposite a leg 13 of the frame profile 2, the part of the leg 13 not covered by the fold 12 forming a third groove 14. A bar 15 made of a material with a low thermal conductivity, such as cement-bonded silicate, is arranged in the groove 14 and in this way essentially covers the frame profile 2 on the relevant side of the door leaf 1, insofar as this is not covered by the door leaf 1.

Auf der anderen Seite des Türblattes 1 ist ein Profilschenkel 16 des Zargenprofils 2 gleichfalls durch eine Leiste 17 aus einem Material mit einer geringen Wärmeleitfähigkeit abgedeckt. Die Leiste 17 erstreckt sich dabei über die volle Länge und Breite des Schenkels 16 und ist ihrerseits von einem im wesentlichen L-förmig abgewinkelten Blechstreifen 18 verkleidet.On the other side of the door leaf 1, a profile leg 16 of the frame profile 2 is also covered by a strip 17 made of a material with a low thermal conductivity. The strip 17 extends over the full length and width of the leg 16 and is in turn covered by a substantially L-shaped angled sheet metal strip 18.

Auf diese Weise ist das Zargenprofil 2 auf der betreffenden Seite des Türblattes 1 hochwirksam vor einer unmittelbaren Hitzeeinwirkung geschützt, sofern dieser Bereich des Zargenprofils dem Raum zugewandt ist, in welchem der Brandherd entstanden ist.In this way, the frame profile 2 on the relevant side of the door leaf 1 is highly effectively protected against direct heat, provided that this area of the frame profile faces the room in which the source of the fire originated.
