Description
Gegenstand der Erfindung ist ein Feuerschutzabschluss bestehend aus mehreren Schichten eines elastischen feuerfesten Material zum Schließen von Öffnungen in Gebäudewänden und zum Schutz der Räume vor der Ausbreitung von Feuer.The invention relates to a fire protection closure consisting of several layers of an elastic refractory material for closing openings in building walls and for protecting the rooms against the spread of fire.
Bekannt ist ein feuerfester Tormantel, eigentlich ein Rollbehang der in der Beschreibung der polnischen Patentanmeldung P -
Der aus mehreren Schichten eines elastischen feuerfesten Materials bestehende Feuerschutzabschuss, mit mindestens einer Tragschicht aus feuerfestem Material, an der leistenförmige Laschen aus feuerfestem Material befestigt sind und von denen jede mit einer ihrer Längskanten befestigt ist, wobei mindestens eine Oberfläche der Lasche eine Quellbeschichtung aus einem Material besitzt, das bei Erhitzung dicker wird, zeichnet sich gemäß der Erfindung dadurch aus, dass der Feuerschutzabschluss eine Tragschicht und eine Oberschicht besitzt, wobei die Oberschicht auf der Laschenseite an der Tragschicht anliegt, und dass die Quellbeschichtung angeordnet ist auf der Oberfläche der Seite der Lasche, die an die Tragschicht anliegt, und wo jede Lasche im gequollenen Zustand ihrer Quellbeschichtung von der Oberfläche der Tragschicht weg geneigt ist und mit dem freien Rand auf die Oberfläche der anliegenden Oberschicht aufliegt.Known is a fireproof door jacket, actually a roll curtain which in the description of the Polish patent application P -
The fire protection section consisting of several layers of an elastic refractory material, with at least one base layer made of refractory material, to which strip-shaped flaps made of refractory material are fastened and each of which is fastened with one of its longitudinal edges, at least one surface of the flap being a swelling coating made of one material , which becomes thicker when heated, is distinguished according to the invention in that the fire protection closure has a base layer and a top layer, the top layer lying on the tab side against the base layer, and in that the swelling coating is arranged on the surface of the side of the tab , which lies against the base layer, and where each flap is inclined in the swollen state of its swelling coating away from the surface of the base layer and rests with the free edge on the surface of the adjacent top layer.
So entstehen zwischen den voneinander entfernten Schichten und den gekippten Laschen isolierende Luftkanäle. Von Vorteil ist es, wenn die Tragschicht des Feuerschutzabschlusses aus Keramikfasergewebe, Glasfasergewebe oder Keramikfaserwolle ist- Die isolierenden Eigenschaften der Tragschicht verbessern sich erheblich, wenn sie mit einer Schicht aus Alufolie bedeckt ist, die Wärmestrahlung reflektiert. Dieser Effekt verstärkt sich weiter, wenn die Tragschicht auf beiden Seiten mit einer Schicht Alufolie bedeckt ist. Der Feuerschutzabschluss mit einer Tragschicht verfügt über eine Oberschicht, die auf der Laschenseite an der Tragschicht anliegt. Die Oberschicht des Feuerschutzabschlusses sollte am besten aus Keramikfasergewebe oder Glasfasergewebe sein. Die isolierenden Eigenschaften der Oberschicht verbessern sich erheblich, wenn sie mit einer Schicht aus Alufolie bedeckt ist. Besonders gut ist, wenn diese Schicht Alufolie außen mit einer Quellbeschichtung bedeckt ist. Je nach Bedarf kann die Fläche der Tragschicht auf der Laschenseite mit einer Quellbeschichtung bedeckt sein. Die Laschen sind zwar nebeneinander platziert, wobei benachbarte Laschen jedoch mit ihren gegenüberliegenden Längskanten an der Tragschicht befestigt sind, so dass die Laschen im gequollenen Zustand ihrer Quellbeschichtung in verschiedene Richtungen geneigt sind. Je nach der erforderlichen Feuerbeständigkeit des Feuerschutzabschlusses sind die Laschen auf beiden Seiten der Tragschicht befestigt. Bei dieser Lösung sind die Laschen einander gegenüber oder überlappend auf beiden Seiten der Tragschicht angeordnet. Wenn der Feuerschutzabschluss die Form eines Rollbehangs hat, sind die Längskanten der Laschen der Tragschicht waagerecht ausgerichtet. Bei einer stationären Anwendung des Feuerschutzabschlusses, wenn dieser in einem Stützrahmen befestigt ist und eine Trennwand bildet, sind die Längskanten der Laschen der Tragschicht senkrecht ausgerichtet, wobei sie jedoch bei Bedarf auch waagerecht ausgerichtet sein können. Zur Wahrung der Elastizität des Feuerschutzabschlusses, können die Laschen mit Hilfe von Metallklammern an der Tragschicht befestigt werden.
Dank dieser Lösung zeichnet sich der Feuerschutzabschluss durch geringen Materialverbrauch und niedrige Herstellungskosten, sowie eine hohe Feuerbeständigkeit bis zu 120 Minuten aus. Je nach der Breite der leistenförmigen Laschen beträgt die Stärke des Feuerschutzabschlusses in kaltem Zustand von 12 bis 30 mm. Bei Erhitzung während eines Brandes auf eine Temperatur von rund 1100°C verdickt sich der Feuerschutzabschluss auf bis zu etwa 80 mm.This creates insulating air channels between the layers that are separated from each other and the tilted tabs. It is advantageous if the base layer of the fire protection closure is made of ceramic fiber fabric, glass fiber fabric or ceramic fiber wool. The insulating properties of the base layer improve considerably if it is covered with a layer of aluminum foil that reflects the heat radiation. This effect is further intensified if the base layer is covered with a layer of aluminum foil on both sides. The fire protection closure with a base layer has over an upper layer, which lies against the base layer on the tab side. The top layer of the fire protection closure should best be made of ceramic fiber or glass fiber. The insulating properties of the top layer improve considerably if it is covered with a layer of aluminum foil. It is particularly good if this layer of aluminum foil is covered on the outside with a swelling coating. Depending on requirements, the surface of the base layer on the tab side can be covered with a swelling coating. The tabs are indeed placed next to one another, but adjacent tabs are attached to the base layer with their opposite longitudinal edges, so that the tabs are inclined in different directions in the swollen state of their swelling coating. Depending on the required fire resistance of the fire protection closure, the tabs are attached on both sides of the base layer. In this solution, the tabs are arranged opposite or overlapping on both sides of the base layer. If the fire protection closure is in the form of a roll curtain, the longitudinal edges of the straps of the base course are aligned horizontally. In a stationary application of the fire protection closure, if it is fastened in a support frame and forms a partition, the longitudinal edges of the tabs of the base layer are oriented vertically, but if necessary they can also be oriented horizontally. In order to maintain the elasticity of the fire protection closure, the tabs can be attached to the base layer using metal clips.
Thanks to this solution, the fire protection closure is characterized by low material consumption and low manufacturing costs, as well as a high one Fire resistance up to 120 minutes. Depending on the width of the strip-shaped tabs, the thickness of the fire protection closure when cold is from 12 to 30 mm. When heated to a temperature of around 1100 ° C during a fire, the fire protection closure thickens up to about 80 mm.
