Abstract
Description
Die Erfindung betrifft eine Brandschutztüre entsprechendThe invention relates accordingly to a fire door
dem Oberbegriff des Anspruchs 1.the preamble of claim 1.
Derartige Brandschutztüren sind bekannt, haben jedoch den Nachteil, daß ihre Bruch- und Biegefestigkeit gering ist, so daß sie häufig schon beim Transport oder auf der Baustelle beschädigt werden. Es ist weiterhin bekannt, eine Brandschutztüre mit mineralischem Aufbau aus Schichten unterschiedlicher Dichte herzustellen, die senkrecht zur Türebene verlaufen. Die Herstellung einer solchen Türe ist jedoch kompliziert und teuer.Such fire doors are known, but have the disadvantage that their breaking and bending strength is low, so that they are often already during transport or be damaged on the construction site. It is also known to have a fire door with a mineral structure made up of layers of different densities, the run perpendicular to the door level. The production of such a door is, however complicated and expensive.
Der Erfindung liegt die Aufgabe zugrunde, die Brandschutztüre der eingangs genannten Gattung derart auszubilden, daß sich eine hohe Bruch- und Biegefestigkeit ergibt.The invention is based on the object of the fire door to be designed in such a way that a high breaking strength and flexural strength results.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.This object is achieved according to the invention by the in the characterizing Part of claim 1 specified features.
Durch die vorgeschlagene Ausbildung kann die Brandschutztüre aus Platten hergestellt werden, deren Dichte so gewählt ist, daß eine möglichst hohe Festigkeit bei geringem Gewicht erreicht wird. Durch Verwendung des Stahldrahtgitters wird eine sowohl für den Trans1>ort als auch für den Gebrauch ausreichend biege- und bruchsichere Türe geschaffen. Außerdem wird durch das Stahldrahtgitter die Einbruchsicherheit erhöht.Due to the proposed design, the fire door can be made of panels are produced, the density of which is chosen so that the highest possible strength is achieved with low weight. By using the steel wire mesh one that is sufficiently flexible and flexible for both transport and use break-proof door created. In addition, the steel wire grille makes it burglar-proof elevated.
Zur Verankerung von Schrauben, die Türbeschläge am Türrahmen befestigen, ist es üblich, in den Rahmen eine Metalleiste einzusetzen. Eine solche Metalleiste hat jedoch den Nachteil, daß ihre Wärmeleitfähigkeit zu hoch ist und dadurch die an eine Feuerschutztüre gestellten Vorschriften nicht mehr erfüllt werden, Dieser Nachteil läßt sich dadurch beseitigen, daß statt einer Metalleiste eine in Silikarleim eingebettete Holzleiste in den Rahmen eingesetzt wird. Die Holzleiste kann dadurch hergestellt werden, daß dünne, geschälte, mit Kunstharz getränkte Buchenfurniere kreuzweise in mehreren Lagen unter hohem Druck zu Platten verpreßt und danach zu Leisten geschnitten werden.For anchoring screws that attach door fittings to the door frame, it is common to insert a metal bar into the frame. Such a metal bar however, has the disadvantage that its thermal conductivity is too high and thereby the Regulations placed on a fire door are no longer met, This disadvantage can be eliminated by the fact that instead of a metal strip a wooden strip embedded in silica glue is inserted into the frame. The wooden strip can be produced by thin, peeled beech veneers impregnated with synthetic resin Crushed crosswise in several layers under high pressure to form panels and then closed Lasts are cut.
Die Erfindung wird nachstehend anhand der anliegenden Zeichnung beispielsweise erläutert, die einen Querschnitt eines Teils einer Feuerschutztüre zeigt.The invention is illustrated below with reference to the accompanying drawing, for example which shows a cross section of part of a fire door.
Die Türe 11 hat einen ungeteilten Rahmen 12 mit minerali-3 schem Aufbau und einer Dichte von etwa 800 bis 1000 kg/ cm'3 Innerhalb des Rahmens befindet sich eine Füllung 13 ebenfalls mit mineralischem Aufbau und einer Dichte von etwa 300 bis 400 kg/cm3. Der Rahmen und die Füllung sind beidseitig mit einer Beplankung ebenfalls mit mineralischem Aufbau und einer Dichte von etwa 600 bis 800 kg/cm3 versehen. Der Rahmen, die Füllung und die Beplankung sind aus gegebenenfalls entsprechend geschnittenen Platten hergestellt.The door 11 has an undivided frame 12 with a mineral structure and a density of about 800 to 1000 kg / cm -3 within the frame a filling 13 also with a mineral structure and a density of about 300 up to 400 kg / cm3. The frame and the filling are planked on both sides also with a mineral structure and a density of around 600 to 800 kg / cm3 Mistake. The frame, the filling and the planking are made accordingly cut panels made.
Zur Befestigung eines Beschlages 17 an der Türe sind Schrauben 16 in den Rahmen 13 geschraubt. Da die Schrauben in der Füllung 13 keinen ausreichenden Halt haben, ist in den Rahmen eine in Silikatleim eingebettete Holzleiste 18 eingesetzt, durch die sich die Schraubenenden erstrecken.Screws 16 are used to fasten a fitting 17 to the door screwed into the frame 13. Since the screws in the filling 13 are insufficient A wooden strip 18 embedded in silicate glue is inserted into the frame, through which the screw ends extend.
Durch die Einbettung in Silikatleim ergibt sich ein luftdichter und feuerfester Übergang zwischen dem Rahmen 12 bzw. der Füllung 13 und der Holzleiste, der die Forderungen der Brandprüfung erfüllt.The embedding in silicate glue results in an airtight and Fireproof transition between the frame 12 or the filling 13 and the wooden strip, that meets the requirements of the fire test.
Zwischen der Beplankung 14 einerseits und dem Rahmen 12 und der Füllung 13 andererseits ist ein Stahldrahtgitter eingepret, das bei einem Drahtdurchmesser von etwa 1,2 bis 1,5 mm eine Maschenweite von etwa 15 bis 25 mm hat.Between the planking 14 on the one hand and the frame 12 and the filling 13, on the other hand, a steel wire mesh is pressed in, with a wire diameter of about 1.2 to 1.5 mm has a mesh size of about 15 to 25 mm.
In den meisten Fällen genügt es, nur auf eirr Seite der Türe ein solches Drahtgitter vorzusehen.In most cases it is sufficient to only have one on one side of the door Wire mesh to be provided.
