Description

Die Erfindung betrifft eine Feuerschutztür aus Asbest-Silikat-Material mit einem Rahmen und mit Deckplatten, die den Rahmen und die zwischen diesem liegende Füllplatte abdecken, wobei der obere und die seitlichen Teile des Rahmens und die Deckplatten durch zwei Brandschutzstreifen abgedeckt sind, die durch einen gut wärmeleitenden Materialstreifen getrennt sind.The invention relates to a fire protection door made of asbestos-silicate material with a frame and with cover plates which cover the frame and the filling plate lying between them, the upper and the lateral parts of the frame and the cover plates being covered by two fire protection strips which are covered by a good heat-conducting material strips are separated.

Es sind die unterschiedlichsten Feuerschutztüren bekannt. Haüfig bestehen diese aus einem Stahlrahmen und Stahlplatten. Diese Feuerschutztüren sind sehr schwer, sie lassen sich nachträglich nicht in ihren Maßen verändern und sie werden den neueren Anforderungen für den Brandschutz nicht mehr gerecht.A wide variety of fire protection doors are known. These often consist of a steel frame and steel plates. These fire protection doors are very heavy, their dimensions cannot be changed afterwards and they no longer meet the newer requirements for fire protection.

Weiterhin ist eine Feuerschutztür der eingangs genannten Art bekannt, bei der die beiden Brandschutzstreifen durch den gut wärmeleitenden Materialstreifen voneinander getrennt sind. Der gut wärmeleitende Materialstreifen sorgt zwar dafür, daß die Wärme gleichmäßig verteilt wird, so daß die Brandschutzstreifen gleichmäßig aufschaümen. Der zweite Brandschutzstreifen schäumt aber gleichzeitig mit dem ersten auf. (FR - A 1 517 444).Furthermore, a fire protection door of the type mentioned at the outset is known, in which the two fire protection strips are separated from one another by the highly heat-conducting material strip. The good heat-conducting material strip ensures that the heat is distributed evenly, so that the fire protection strips foam up evenly. The second fire protection strip foams at the same time as the first. (FR - A 1 517 444).

Weiterhin ist eine Feuerschutztür aus Metall bekanntgeworden, bei der außen an dem als Hohlprofil ausgebildeten Metallrahmen mehrere Brandschutzstreifen angeordnet sind, zwischen denen eine Befestigungsplatte aus Metall liegt. Gehalten werden diese Teile durch eine in den Metallrahmen eingeschraubte und durch sie hindurchgehende Schraube. Zwischen dem Metallrahmen und der Füllung ist ein weiterer Brandschutzstreifen vorgesehen, der so breit ist, wie der Metallrahmen (DE-OS 25 25 309).Furthermore, a fire protection door made of metal has become known, in which several fire protection strips are arranged on the outside of the metal frame designed as a hollow profile, between which there is a metal fastening plate. These parts are held by a screw that is screwed into and through the metal frame. Another fire protection strip is provided between the metal frame and the filling, which is as wide as the metal frame (DE-OS 25 25 309).

Der Erfindung liegt nun die Aufgabe zugrunde, eine Feuerschutztür der eingangs genannten Art zu schaffen, die den erhöhten Anforderungen des Brandschutzes, insbesondere der Standzeiten im Brandfalle gerecht wird und darüberhinaus einfach aufgebaut ist und auch noch eine Anpassung ihrer Maße auf der Baustelle ermöglicht.The invention is based on the object of creating a fire door of the type mentioned which meets the increased requirements of fire protection, in particular the downtimes in the event of a fire, and is also simple in construction and also allows its dimensions to be adapted on the construction site.

Diese Aufgabe wird grundsätzlich dadurch gelöst, daß zwischen dem am Rahmen anliegenden Brandschutzstreifen und dem Materialstreifen eine Rahmenleiste angeordnet ist.This object is basically achieved in that a frame strip is arranged between the fire protection strip resting on the frame and the material strip.

Erfindungsgemäß sind die beiden Brandschutzstreifen nicht nur durch den gut wärmleitenden Materialstreifen sondern zusätzlich durch die Rahmenleiste getrennt. Hierdurch wird erreicht, daß der Brandschutzstreifen, der unmittelbar an dem gut wärmeleitenden Materialstreifen anliegt, zuerst aufschäumt. Erst später, wenn die Wärmeentwicklung anhält und zunimmt, schäumt auch der zweite Brandschutzstreifen auf. Die Ausdehnung der beiden Brandschutzstreifen erfolgt also zeitlich aufeinander. Hierdurch wird die Standzeit der Feuerschutztür im Brandfalle erheblich verlängert. Tests haben gezeigt, daß die neueren, verschärften Anforderungen für den Brandschutz über 100 Minuten eingehalten werden. Dieses übertrifft bisherige Feuerschutztüren. Durch das Zusammenwirken der beiden Brandschutzstreifen üben diese entsprechend seitlich gerichtete hohe Druckkräfte auf die Tür aus, wodurch einem Auswölben der Tür entgegengewirkt wird. Die Brandschutzstreifen, auch der an zweiter Stelle wirksam werdende, erstrecken sich praktisch über die gesamte Breite des Türblattrahmens.According to the invention, the two fire protection strips are not only separated by the good heat-conducting material strip but also by the frame strip. It is hereby achieved that the fire protection strip, which is in direct contact with the highly heat-conducting material strip, first foams. Only later, when the heat development continues and increases, does the second fire protection strip foam up. The expansion of the two fire protection strips takes place over time. This significantly extends the service life of the fire protection door in the event of a fire. Tests have shown that the new, stricter fire protection requirements are met for over 100 minutes. This surpasses previous fire protection doors. Through the interaction of the two fire protection strips, they exert correspondingly laterally directed high compressive forces on the door, which counteracts arching of the door. The fire protection strips, including those that take effect second, extend practically across the entire width of the door leaf frame.

Bei den Brandschutzstreifen handelt es sich um ein für diesen Zweck grundsätzlich bekanntes Produkt. Dieses Produkt besteht aus einem Kern aus im wesentlichen wasserhaltigem Natriumsilikat. Die Kernschicht enthält ferner geringe Mengen organischer Zusätze sowie Glasfasern und ein Glasgewebe oder ein Drahtnetz. Eine beidseitige Epoxidharzschicht schützt den Kern gegen atmosphärische Einflüsse, insbesondere des Kohlendioxids. Sie lassen sich in einem Temperaturbereich zwischen 60 und 100°C plastisch verformen. Über 100°C vergrößern sie ihr Volumen, insbesondere durch Aufschäumen. Es entsteht eine unbrennbare, feinporige, rißfeste, druckfeste und hitzebeständige Schaumschicht, deren Schmelzbereich bei über 900°C liegt. Beim Aufschaümen entsteht ein verhältnismäßig hoher Druck.The fire protection strips are basically known products for this purpose. This product consists of a core of essentially water-containing sodium silicate. The core layer also contains small amounts of organic additives as well as glass fibers and a glass fabric or a wire mesh. A double-sided epoxy resin layer protects the core against atmospheric influences, especially carbon dioxide. They can be plastically deformed in a temperature range between 60 and 100 ° C. They increase their volume above 100 ° C, especially by foaming. The result is an incombustible, fine-pored, crack-resistant, pressure-resistant and heat-resistant foam layer, the melting range of which is over 900 ° C. When foaming occurs, a relatively high pressure is created.

In vorteilhafter Weise kann die Feuerschutztür derart ausgebildet sein, daß die Füllplatte aus Asbest-Silikat-Material geringerer Dichte als die Deckplatten besteht. Hierdurch wird ohne Verlust der Schutzwirkung das Gewicht der Tür herabgesetzt.Advantageously, the fire door can be designed such that the filler plate is made of asbestos silicate material of lower density than the cover plates. As a result, the weight of the door is reduced without losing the protective effect.

Bei dem wärmleitenden Material kann es sich in vorteilhafter Weise um einen Aluminiumstreifen handeln.The heat-conducting material can advantageously be an aluminum strip.

Wie in den Ansprüchen 3 bis 5 angegeben, kann eine Abdeckung mit verschiedenen Holzmaterialien vorgenommen werden. Die Abdeckung der Brandschutzstreifen im Bereich der Seiten und im oberen Bereich durch Holzleisten ermöglicht eine Anpassung an der Baustelle durch Abhobeln oder dergl. An der unteren Kante ist ein Brandschutzstreifen nicht vorgesehen, da hier aus bekannten Gründen die Gefahr des Durchschlagens beim Brand sehr viel geringer ist. In diesem Bereich ist insbesondere wegen des Fehlens eines Metallrahmens oder dergl. ein Bearbeiten und ein Anpassen an verschiedene Abmessungen sehr leicht und in einem großen Bereich möglich.As indicated in claims 3 to 5, a covering can be made with different wood materials. The covering of the fire protection strips in the area of the sides and in the upper area by wooden strips enables adaptation to the construction site by planing or the like. A fire protection strip is not provided on the lower edge, since for known reasons the risk of striking through in the event of a fire is very much lower . In this area, particularly due to the lack of a metal frame or the like, machining and adaptation to different dimensions is very easy and possible in a large area.

Ein Problem stellt bei derartigen Feuerschutztüren die Befestigung von Scharnieren, Türschlössern oder dergl. dar. Diese müssen nicht nur sicher und dauerhaft, sondern auch lösbar befestigt werden.A problem with such fire protection doors is the attachment of hinges, door locks or the like. These not only have to be secured securely and permanently, but also releasably.

Insbesondere zur Befestigung der Scharniere kann in vorteilhafter Weise ein Bandstahl zwischen Füllplatte und Rahmen der Scharniere befestigt werden, in den dann ein Gewinde für eine entsprechende Gewindeschraube zur Befestigung des Scharniers eingeschnitten wird. Es ist auch möglich, die Bauteile zusätzlich oder allein durch besondere Schrauben zu befestigen, auf deren Gewinde eine Schraubenfeder sitzt. Diese Schraubenfeder wird nach Bohrung des Gewindeloches beim ersten Einschrauben in dem Gewindeloch befestigt, d.h. sie verbleibt beim Lösen der Schraube in dem Gewindeloch und bildet so das Gewinde in dem Material, das hierzu normalerweise sehr schlecht geeignet ist.Especially for fixing the hinges a steel strip can advantageously be fastened between the filler plate and the frame of the hinges, into which a thread for a corresponding threaded screw for fastening the hinge is then cut. It is also possible to attach the components additionally or solely by means of special screws, on the thread of which a coil spring is seated. After the threaded hole has been drilled, this helical spring is fastened in the threaded hole the first time it is screwed in, ie it remains in the threaded hole when the screw is loosened and thus forms the thread in the material which is normally very poorly suited for this purpose.

Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.Further advantages and details of the invention are explained in more detail below with reference to the drawing using an exemplary embodiment.

Es zeigt:

  • Fig. 1 einen Teilquerschnitt durch eine Ausführungsform einer Feuerschutztür nach der Erfindung; und
  • Fig. 2 einen Längsausschnitt im Bereich eines Scharniers der Feuerschutztür nach Fig. 1.
It shows:
  • 1 shows a partial cross section through an embodiment of a fire door according to the invention. and
  • FIG. 2 shows a longitudinal section in the area of a hinge of the fire protection door according to FIG. 1.

Die in der Zeichnung dargestellte Feuerschutztür besteht aus einem Rahmen 2 und Rahmenleisten 4 aus Asbest-Silikat-Material. In diesem Rahmen liegt eine Füllplatte 1, die durch Deckplatten 3 abgedeckt ist. Das Asbest-Silikat-Material der Füllplatte weist vorzugsweise eine geringere Dichte auf.The fire door shown in the drawing consists of a frame 2 and frame strips 4 made of asbestos-silicate material. In this frame is a filler plate 1, which is covered by cover plates 3. The asbestos-silicate material of the filling plate preferably has a lower density.

Auf der Außenseite der Rahmenleiste 4 befindet sich im Bereich der oberen Kante und im seitlichen Bereich ein Brandschutzstreifen 5 der eingangs definierten Art, wobei zwischen Brandschutzstreifen 5 und Rahmenleiste 4 ein Aluminiumstreifen 7 vorgesehen ist. Auf der anderen Seite der Rahmenleiste 4 ist ebenfalls ein Brandschutzstreifen 6, jedoch ohne zusätzlichen Aluminiumstreifen, vorgesehen. Außen ist der Brandschutzstreifen 5 durch eine Holzleiste 8 abgedeckt. Der gesamte Aufbau ist an den Außenflächen durch furniertes Sperrholz 9 geschützt.A fire protection strip 5 of the type defined at the outset is located on the outside of the frame strip 4 in the region of the upper edge and in the lateral region, an aluminum strip 7 being provided between the fire protection strip 5 and the frame strip 4. On the other side of the frame strip 4, a fire protection strip 6 is also provided, but without an additional aluminum strip. Outside, the fire protection strip 5 is covered by a wooden strip 8. The entire structure is protected on the outer surfaces by veneered plywood 9.

Das Asbest-Silikat-Material der Platten 1 und 3 ist durch einen Komponentenkleber 12 verklebt. Zusätzlich sind Schrauben 13 zur Befestigung vorgesehen. Das furnierte Sperrholz 9 ist durch einen Kontaktkleber 11 aufgeklebt. Ebenso sind die Brandschutzstreifen durch Kleben befestigt.The asbestos-silicate material of plates 1 and 3 is glued by a component adhesive 12. In addition, screws 13 are provided for attachment. The veneered plywood 9 is glued on by a contact adhesive 11. The fire protection strips are also attached by gluing.

Wie sich insbesondere beim Betrachten der Fig. 2 ergibt sind die Scharniere durch Gewindeschrauben 15 befestigt, deren Mutterngewinde in einem Bandstahl 10 ausgebildet ist. Dieser Bandstahl 10 liegt zwischen dem Rahmen 2 und der Füllplatte 1 (siehe auch Fig. 2). Wenn die genaue Lage des Scharniers festliegt, wird das entsprechende Loch bis in den Bereich des Bandstahls gebohrt. Es kann dann ein Gewinde in den Bandstahl geschnitten werden, in das die Schraube lösbar eingeschraubt werden kann und für eine sichere Befestigung sorgt. Zusätzlich können für das Scharnier und insbesondere auch zur Befestigung des nicht gezeigten Türschlosses Schrauben 16 vorgesehen sein, die mit einer getrennt ausgebildeten und dem Gewinde angepaßten Schraubenfeder 17 ausgerüstet sind. Diese Schraubenfeder ist selbstschneidend und verbleibt beim ersten Befestigen der Schraube in dem Asbest-Silikat-Material und stellt praktisch das Muttergewinde für die Schraube dar.As can be seen in particular when looking at FIG. 2, the hinges are fastened by threaded screws 15, the nut thread of which is formed in a strip steel 10. This steel strip 10 lies between the frame 2 and the filler plate 1 (see also FIG. 2). When the exact position of the hinge is determined, the corresponding hole is drilled into the area of the steel strip. A thread can then be cut into the steel strip into which the screw can be removably screwed and ensures secure fastening. In addition, screws 16 can be provided for the hinge and in particular also for fastening the door lock, not shown, which are equipped with a separately designed coil spring 17 adapted to the thread. This coil spring is self-tapping and remains in the asbestos-silicate material when the screw is first fastened and practically represents the nut thread for the screw.

Bei einer Ausführungsform wurde für das Füllmaterial ein Asbest-Silikat-Material mit einem Raumgewicht von 192 kg/m3 gewählt. Die Deckplatten und Rahmenleisten hatten ein Raumgewicht von 960 kg/m3, wohingegen das Raumgewicht des Rahmens 2 720 kg/m3 betrug. Dieses ist lediglich ein Ausführungsbeispiel.In one embodiment, an asbestos-silicate material with a density of 192 kg / m 3 was chosen for the filling material. The cover plates and frame strips had a density of 960 kg / m 3 , whereas the density of the frame was 2 720 kg / m 3 . This is only one embodiment.

Die Fig. 2 ist eine vereinfachte Darstellung, in der die Brandschutzstreifen und die Rahmenleiste 4 nicht gezeigt sind.FIG. 2 is a simplified illustration in which the fire protection strips and the frame strip 4 are not shown.
