Definitions
- the invention relates to a glass door for fire protection purposes, in particular for use within a fire protection glazing to prevent the passage of fire and smoke in the event of a fire from one room to another, with at least one fire protection pane containing a foaming agent as a protective agent, which is held by a pivotable door frame, which has a door profile which is arranged on a vertical end face of the fire protection pane and which, when the glass door is closed, lies against a fixed frame profile via seals.
- Fire-resistant glazing is translucent components that are designed not only to prevent the spread of fire and smoke, but also to prevent the inadmissible transfer of heat, depending on their fire resistance. Fire protection glazing is divided into different fire resistance classes, the respective requirements of which are explained in DIN 4102.
- a known fire protection glazing has fire protection panes which are constructed in multiple layers from glass panes with a fire protection layer arranged in between. In the event of a fire, the fire protection layer is activated. they absorbs heat radiation and forms a highly effective insulation layer. The originally transparent glazing creates a practically opaque fire protection wall.
- a known glass door for fire protection purposes has a steel frame construction which surrounds the inserted fire protection pane on all sides and is hinged to a door frame.
- the steel frame construction consists of an approximately 60mm wide steel hollow profile, on the inner edge of which the fire protection pane is attached via glass retaining strips.
- a further, but narrower designed hollow steel profile is fastened, which is provided with an angled portion which, when the glass door is closed, bears against an appropriately designed hollow steel profile of the door frame by means of an intermediate seal.
- the disadvantage of this known glass door is that it is constructed in a very complex manner.
- the glass door has a total of four hollow steel profiles, taking into account the glass retaining strips designed as steel tubes.
- Another known glass door for fire protection uses a two-part steel frame construction in which the space between the two steel frames is filled by a strip made of non-combustible or flame-retardant material. In this way, the heat transfer through the steel frame construction is significantly reduced.
- a disadvantage of this known glass door is that in order to ensure the required mechanical stability, the frame halves located on both sides of the fire protection window and the strip must be welded or screwed together.
- the invention has for its object to avoid the disadvantages of the prior art described to create a simply constructed glass door for fire protection purposes, the components of which do not require additional fire protection measures, such as the insulation of the load-bearing structure. Nevertheless, the possible thermal bridges should be reduced to a minimum.
- the door profile of the door frame is designed as a flat profile, to which the adjacent abutting surface of the fire protection window is adjacent, forming a narrow joint without insulation, and that in the event of a fire, the foam is made fire-proof and smoke-tight by the foaming agent of the fire protection window and under simultaneous cooling of the adjacent part of the door profile is closed.
- the invention is based on the finding that even without additional insulation measures in the form of strips or strips of non-combustible or flame-retardant material, flames and smoke do not penetrate the abutting surfaces of the fire shield in the event of a fire. So far it has been assumed that the abutting surfaces of the fire protection panes represent a weak point of fire protection glazing, since in the event of fire they represent the easiest way for the flames, smoke and heat to penetrate fire protection glazing or a glass door for fire protection purposes.
- This joint closure not only means that flames and smoke can no longer penetrate through the glass door, but also leads to local cooling of the flat profile opposite the joint surface, forming the joint.
- the flat profile is the only possible thermal bridge, its cooling by the foam emerging from the fire protection window leads to a significant reduction in the heat transfer at the edge of the glass door for a certain period of time and thus to improved fire protection properties of the glass door.
- a completely flat, i.e. just designed profile can be understood, but a profile that, for example, also as a hollow profile, is designed so narrow that in the event of fire, the cooling effect reliably occurs through the escaping foam.
- the glass door which can have one or two leaves, undergoes a further development in that the frame profile is also designed as a flat profile, to which the butt surface of a further fire protection pane is adjacent, forming a corresponding joint.
- This achieves the advantage of a significant reduction in the effective thermal bridges not only in the area of the frame, but also in the door frame of the glass door.
- a particularly stable and elegant glass door for fire protection purposes is achieved by connecting a strip-shaped joint cover to the door profile on one or both sides.
- the joint cover can be designed, for example, as a hollow steel profile, which can easily be painted to adapt to the respective environment. Surface treatment is also possible.
- a further development of the glass door has a bend formed on the door profile and connected to the hinge.
- the bend is formed on the component that also requires a special adjustment in other respects, for example with regard to door seals and other fitting parts.
- the joint covers can be kept free of fittings, which means that they can be designed in a uniform manner, which in turn benefits the optical appearance of the glass door.
- the glass door 1 shown in the drawing is part of a fire protection glazing, of which two fire protection panes 2a are shown in the drawing.
- the flat sides of the fire protection panes 2a are provided in the region of their edge with hollow profiles 3 which form the outer frame of the respective fire protection panes 2a.
- hollow profiles 3 which form the outer frame of the respective fire protection panes 2a.
- elastocellular strips 4 In the gaps between the edges of the fire protection panes 2a and the inner surfaces of the hollow profiles 3 there are elastocellular strips 4, these gaps additionally being sealed in the direction of the center of the pane with a sealing compound 5 made of silicone rubber.
- a door handle 8a for actuating a locking mechanism (not shown) is attached to the hollow profiles 3 opposite the hinge side.
- the fire protection panes 2a, 2b consist of a special laminated glass, which consists of several glass panes with fire protection layers arranged between them. In the event of a fire, these fire protection layers are activated, whereby they absorb heat radiation and thus form an effective insulation layer that prevents the passage of fire and smoke. The activation of the fire protection layers in the event of fire causes them to foam up and become cloudy, so that practically an opaque fire protection wall is created.
- the glass door 1 is provided on its vertical edges with the door profile 8, which is on the end faces the hollow profile 3 of the glass door 1 is fastened and together with the corresponding two hollow profiles 3 forms the door frame 7 of the glass door.
- the door profiles 8 abut seals 9 on likewise flat frame profiles 10, which are fastened to corresponding end faces of the hollow profiles 3 of the fire protection glazing.
- the door profiles 8 of the door frame 7 and the frame profiles 10 are designed as flat profiles; However, this does not rule out that both profiles have bends 11, 12, the bends 11 serving for sealing contact of the glass door 1 in the closed state, while the bend 12 establishes the connection between one of the door profiles 8 and the hinge 6 designed as a hinge 6 .
- a joint 14 with a joint width f of at most 6mm remains between the respective fire protection panes 2a, 2b facing surfaces of the door profiles 8 or the frame profiles 10 and the adjacent abutting surfaces 13a or 13b of the fire protection panes 2a or 2b.
- the joint width f of the joint 14 is less than 4 mm.
- the flat frame profiles 10 and door profiles 8 in the area of the abutting surfaces 13a and 13b are slightly recessed in the direction of the respective pane.
- the fire protection layer located therein is foamed as a result of the heating of the fire protection panes 2a, 2b, the material of this foam emerging from the abutting surfaces 13a, 13b of the fire protection panes 2a, 2b and closing the joints 14, so that flames and smoke no longer pass through the joints 14 can get through.
- the foam emerging from the abutting surfaces 13a, 13b cools the adjacent frame profile 10 or door profile 8, so that the transfer of heat via the frame profiles 10 or door profiles 8 is made more difficult.
- the optical structure of the glass door 1 in the glass part having the fire protection pane 2b and in the edge part covered with the hollow profiles 3 matches the corresponding structure of the other areas of the fire protection glazing, the overall result is a uniform visual impression of the fire protection glazing.
- the glass door 1 due to the narrow door profiles 8 and frame profiles 10, gives the impression of lightness and thus clearly stands out from the known glass doors, which generally have voluminous frame structures.

Abstract
Description
Die Erfindung betrifft eine Glastür für Brandschutzzwecke, insbesondere zur Verwendung innerhalb einer Brandschutzverglasung zur Vermeidung des Durchtritts von Feuer und Rauch im Brandfall von einem Raum in einen anderen, mit mindestens einer ein aufschäumendes Mittel als Schutzwirkstoff enthaltenden Brandschutzscheibe, die von einem verschwenkbaren Türrahmen gehalten ist, der ein an einer senkrechten Stirnfläche der Brandschutzscheibe angeordnetes Türprofil aufweist, welches bei geschlossener Glastür über Dichtungen an einem feststehenden Zargenprofil anliegt.The invention relates to a glass door for fire protection purposes, in particular for use within a fire protection glazing to prevent the passage of fire and smoke in the event of a fire from one room to another, with at least one fire protection pane containing a foaming agent as a protective agent, which is held by a pivotable door frame, which has a door profile which is arranged on a vertical end face of the fire protection pane and which, when the glass door is closed, lies against a fixed frame profile via seals.
Brandschutzverglasungen sind lichtdurchlässige Bauteile, die dazu bestimmt sind, entsprechend ihrer Feuerwiderstandsdauer nicht nur die Ausbreitung von Feuer und Rauch, sondern zusätzlich auch den unzulässigen Übergang von Wärme zu verhindern. Brandschutzverglasungen werden in verschiedene Feuerwiderstandsklassen eingeteilt, deren jeweilige Anforderungen in DIN 4102 erläutert sind.Fire-resistant glazing is translucent components that are designed not only to prevent the spread of fire and smoke, but also to prevent the inadmissible transfer of heat, depending on their fire resistance. Fire protection glazing is divided into different fire resistance classes, the respective requirements of which are explained in DIN 4102.
Eine bekannte Brandschutzverglasung verfügt über Brandschutzscheiben, welche mehrlagig aus Glasscheiben mit einer jeweils dazwischen angeordneten Brandschutzschicht aufgebaut sind. Im Brandfall wird die Brandschutzschicht aktiviert. Sie absorbiert die Wärmestrahlung und bildet eine hochwirksame Dämmschicht. Aus der ursprünglich transparenten Verglasung entsteht dabei eine praktisch undurchsichtige Feuerschutzwand.A known fire protection glazing has fire protection panes which are constructed in multiple layers from glass panes with a fire protection layer arranged in between. In the event of a fire, the fire protection layer is activated. they absorbs heat radiation and forms a highly effective insulation layer. The originally transparent glazing creates a practically opaque fire protection wall.
Da in den meisten Fällen Brandschutzverglasungen über mindestens eine Türöffnung verfügen müssen, sind Glastüren entwickelt worden, die hinsichtlich ihrer brandschutztechnischen Eigenschaften auf die Brandschutzverglasung als Ganzes abgestimmt sind.Since in most cases fire protection glazing must have at least one door opening, glass doors have been developed which are matched to the fire protection glazing as a whole with regard to its fire protection properties.
Eine bekannte Glastür für Brandschutzzwecke verfügt über eine die eingelegte Brandschutzscheibe allseitig umschließende Stahlrahmenkonstruktion, die über Scharniere schwenkbar an einer Türzarge befestigt ist. Hierbei besteht die Stahlrahmenkonstruktion aus einem etwa 60mm breiten Stahlhohlprofil, an dessen Innenrand über Glashalteleisten die Brandschutzscheibe befestigt ist. Am Außenrand des Stahlhohlprofiles ist ein weiteres, allerdings schmaler gestaltetes Stahlhohlprofil befestigt, das mit einer Abwinklung versehen ist, welche bei geschlossener Glastür mittels einer dazwischenliegenden Dichtung an einem entsprechend gestalteten Stahlhohlprofil der Türzarge anliegt.A known glass door for fire protection purposes has a steel frame construction which surrounds the inserted fire protection pane on all sides and is hinged to a door frame. The steel frame construction consists of an approximately 60mm wide steel hollow profile, on the inner edge of which the fire protection pane is attached via glass retaining strips. At the outer edge of the hollow steel profile, a further, but narrower designed hollow steel profile is fastened, which is provided with an angled portion which, when the glass door is closed, bears against an appropriately designed hollow steel profile of the door frame by means of an intermediate seal.
Nachteilig bei dieser bekannten Glastür ist, daß diese sehr aufwendig aufgebaut ist. Denn sowohl scharnierseitig als auch schloßseitig weist die Glastür bei Berücksichtigung der als Stahlrohre ausgebildeten Glashalteleisten insgesamt vier Stahlhohlprofile auf.The disadvantage of this known glass door is that it is constructed in a very complex manner. For both the hinge side and the lock side, the glass door has a total of four hollow steel profiles, taking into account the glass retaining strips designed as steel tubes.
Nachteilig ist weiterhin, daß die Querschnitte der Stahlhohlprofile im Brandfall Wärmebrücken bilden, so daß hinsichtlich der brandschutztechnischen Eigenschaften im Rahmenbereich einer derartigen Glastür Abstriche gegenüber dem brandschutztechnischen Verhalten der übrigen Brandschutzverglasung bestehen. Innerhalb des Systems Brandschutzverglasung stellt daher eine Glastür immer das schwächste Bauteil dar.Another disadvantage is that the cross sections of the hollow steel profiles form thermal bridges in the event of fire, so that with regard to the fire protection properties in the frame area Such a glass door compromises the fire protection behavior of the other fire protection glazing. A glass door is therefore always the weakest component within the fire protection glazing system.
Um diesem Problem abzuhelfen, verwendet eine weitere bekannte Glastür für Brandschutzzwecke eine zweiteilige Stahlrahmenkonstruktion, bei der der Raum zwischen den beiden Stahlrahmen durch eine Leiste aus nicht brennbarem bzw. schwer entflammbarem Material gefüllt ist. Auf diese Weise wird der Wärmedurchgang durch die Stahlrahmenkonstruktion deutlich vermindert. Nachteilig bei dieser bekannten Glastür ist jedoch, daß zur Gewährleistung der erforderlichen mechanischen Stabilität die beiderseits der Brandschutzscheibe sowie der Leiste befindlichen Rahmenhälften miteinander verschweißt oder verschraubt werden müssen.In order to remedy this problem, another known glass door for fire protection uses a two-part steel frame construction in which the space between the two steel frames is filled by a strip made of non-combustible or flame-retardant material. In this way, the heat transfer through the steel frame construction is significantly reduced. A disadvantage of this known glass door, however, is that in order to ensure the required mechanical stability, the frame halves located on both sides of the fire protection window and the strip must be welded or screwed together.
Der Erfindung liegt die Aufgabe zugrunde, unter Meidung der beschriebenen Nachteile des Standes der Technik eine einfach aufgebaute Glastür für Brandschutzzwecke zu schaffen, deren Bauteile keine zusätzlichen Brandschutzmaßnahmen, wie etwa die Isolierung der tragenden Konstruktion, erfordern. Gleichwohl sollen die möglichen Wärmebrücken auf ein Mindestmaß reduziert werden.The invention has for its object to avoid the disadvantages of the prior art described to create a simply constructed glass door for fire protection purposes, the components of which do not require additional fire protection measures, such as the insulation of the load-bearing structure. Nevertheless, the possible thermal bridges should be reduced to a minimum.
Zur Lösung dieser Aufgabe wird vorgeschlagen, daß das Türprofil des Türrahmens als Flachprofil ausgebildet ist, an das die benachbarte Stoßfläche der Brandschutzscheibe unter Bildung einer schmalen Fuge ohne Isolierung angrenzt und daß die Fuge im Brandfall durch das aufschäumende Mittel der Brandschutzscheibe feuer- und rauchdicht und unter gleichzeitiger Kühlung des angrenzenden Teils des Türprofils verschlossen wird.To solve this problem, it is proposed that the door profile of the door frame is designed as a flat profile, to which the adjacent abutting surface of the fire protection window is adjacent, forming a narrow joint without insulation, and that in the event of a fire, the foam is made fire-proof and smoke-tight by the foaming agent of the fire protection window and under simultaneous cooling of the adjacent part of the door profile is closed.
Dabei liegt der Erfindung die Erkenntnis zugrunde, daß auch ohne zusätzliche Isolationsmaßnahmen in Form von Streifen oder Leisten aus nicht brennbarem bzw. schwer entflammbarem Material im Brandfall ein Durchschlagen von Flammen und Rauch an den Stoßflächen der Brandschutzscheibe nicht eintritt. Bisher ist angenommen worden, daß die Stoßflächen der Brandschutzscheiben einen Schwachpunkt einer Brandschutzverglasung darstellen, da sie im Brandfall für die Flammen, Rauch und Wärme den leichtesten Weg darstellen, eine Brandschutzverglasung bzw. eine Glastür für Brandschutzzwecke zu durchdringen. In Versuchen hat sich jedoch herausgestellt, daß in den Fällen, in denen an den Stoßflächen der Brandschutzscheibe eine Restfuge verbleibt, bei großer Hitzeeinwirkung das zwischen den einzelnen Glasschichten befindliche Brandschutzmittel in Form eines Schaumes aus der stirnseitigen Stoßfläche der Brandschutzscheibe austritt und die Fuge dicht verschließt.The invention is based on the finding that even without additional insulation measures in the form of strips or strips of non-combustible or flame-retardant material, flames and smoke do not penetrate the abutting surfaces of the fire shield in the event of a fire. So far it has been assumed that the abutting surfaces of the fire protection panes represent a weak point of fire protection glazing, since in the event of fire they represent the easiest way for the flames, smoke and heat to penetrate fire protection glazing or a glass door for fire protection purposes. Experiments have shown, however, that in cases where a residual joint remains on the butt surfaces of the fire protection window, the fire protection agent between the individual glass layers emerges in the form of a foam from the end face of the fire protection window and seals the joint tightly in the form of foam.
Dieser Fugenverschluß führt nicht nur dazu, daß Flammen und Rauch nicht mehr durch die Glastür hindurchschlagen können, sondern führt auch zu einer örtlichen Kühlung des der Stoßfläche unter Bildung der Fuge gegenüberliegenden Flachprofils. Da bei der erfindungsgemäßen Glastür das Flachprofil jedoch die einzige mögliche Wärmebrücke darstellt, führt dessen Kühlung durch den aus der Brandschutzscheibe austretenden Schaum zu einer für einen gewissen Zeitraum deutlichen Minderung des Wärmeübergangs am Rand der Glastür und damit zu verbesserten brandschutztechnischen Eigenschaften der Glastür. In diesem Zusammenhang soll unter "Flachprofil" nicht nur ein vollständig flaches, d.h. eben gestaltetes Profil verstanden werden, sondern ein Profil, daß, beispielsweise auch als Hohlprofil, so schmal gestaltet ist, daß im Brandfall der Kühleffekt durch den austretenden Schaum sicher eintritt.This joint closure not only means that flames and smoke can no longer penetrate through the glass door, but also leads to local cooling of the flat profile opposite the joint surface, forming the joint. However, since in the glass door according to the invention the flat profile is the only possible thermal bridge, its cooling by the foam emerging from the fire protection window leads to a significant reduction in the heat transfer at the edge of the glass door for a certain period of time and thus to improved fire protection properties of the glass door. In this context, not only a completely flat, i.e. just designed profile can be understood, but a profile that, for example, also as a hollow profile, is designed so narrow that in the event of fire, the cooling effect reliably occurs through the escaping foam.
Die vorbezeichneten Vorteile werden ohne zusätzliche Isolationsmaßnahmen in Form von innerhalb des Stahlrahmens eingesetzten Leisten oder Streifen aus nicht brennbarem oder schwer entflammbarem Material erreicht. Auch eine Außenisolierung der Profile ist nicht erforderlich, da im Gegensatz zum Stand der Technik keine großflächigen Stahlhohlprofile verwendet werden, sondern Flachprofile, welche der Hitze nur eine geringe Angriffs- und damit Wärmeübertragungsfläche bieten.The above-mentioned advantages are achieved without additional insulation measures in the form of strips or strips of non-combustible or flame-retardant material inserted within the steel frame. An external insulation of the profiles is also not necessary since, in contrast to the prior art, no large-area hollow steel profiles are used, but flat profiles, which offer the heat only a small area of attack and thus heat transfer.
Die Glastür, welche ein- oder zweiflügelig ausgebildet sein kann, erfährt dadurch eine Weiterbildung, daß auch das Zargenprofil als Flachprofil ausgebildet ist, an das die Stoßfläche einer weiteren Brandschutzscheibe unter Bildung einer entsprechenden Fuge angrenzt. Dadurch wird der Vorteil einer deutlichen Minderung der wirksamen Wärmebrücken nicht nur im Bereich des Rahmens, sonder auch der Türzarge der Glastür erreicht.The glass door, which can have one or two leaves, undergoes a further development in that the frame profile is also designed as a flat profile, to which the butt surface of a further fire protection pane is adjacent, forming a corresponding joint. This achieves the advantage of a significant reduction in the effective thermal bridges not only in the area of the frame, but also in the door frame of the glass door.
Eine besonders stabile und formschöne Glastür für Brandschutzzwecke wird erreicht, indem mit dem Türprofil ein- oder beidseitig eine leistenförmige Fugenabdeckung verbunden ist. Die Fugenabdeckung kann beispielsweise als Stahlhohlprofil ausgebildet sein, welches zur Anpassung an die jeweilige Umgebung ohne weiteres lackiert werden kann. Auch eine Oberflächenbehandlung ist möglich.A particularly stable and elegant glass door for fire protection purposes is achieved by connecting a strip-shaped joint cover to the door profile on one or both sides. The joint cover can be designed, for example, as a hollow steel profile, which can easily be painted to adapt to the respective environment. Surface treatment is also possible.
Eine Weiterbildung der Glastür weist eine an dem Türprofil ausgebildete und mit dem Scharnier verbundene Abwinklung auf. Auf diese Weise ist die Abwinklung an jenem Bauteil ausgebildet, welches auch im übrigen eine besondere Anpassung erfordert, beispielsweise im Hinblick auf Türdichtungen und andere Beschlagteile. Dadurch lassen sich die Fugenabdeckungen frei von Beschlagteilen halten, wodurch diese einheitlich gestaltet werden können, was wiederum dem optischen Erscheinungsbild der Glastür zugute kommt.A further development of the glass door has a bend formed on the door profile and connected to the hinge. In this way, the bend is formed on the component that also requires a special adjustment in other respects, for example with regard to door seals and other fitting parts. As a result, the joint covers can be kept free of fittings, which means that they can be designed in a uniform manner, which in turn benefits the optical appearance of the glass door.
Ein Ausführungsbeispiel einer erfindungsgemäßen Glastür für Brandschutzzwecke wird nachfolgend anhand der Zeichnung beschrieben. Die Zeichnung zeigt in verkürzter Darstellung eine Glastür als Teil einer Brandschutzverglasung.An embodiment of a glass door according to the invention for fire protection purposes is described below with reference to the drawing. The drawing shows in an abbreviated form a glass door as part of fire protection glazing.
Die in der Zeichnung dargestellte Glastür 1 ist Bestandteil einer Brandschutzverglasung, von der in der Zeichnung zwei Brandschutzscheiben 2a dargestellt sind. Die Flachseiten der Brandschutzscheiben 2a sind im Bereich ihres Randes mit Hohlprofilen 3 versehen, welche den Außenrahmen der jeweiligen Brandschutzscheiben 2a bilden. In den Spalten zwischen den Rändern der Brandschutzscheiben 2a und den Innenflächen der Hohlprofile 3 befinden sich jeweils Elastozellbänder 4, wobei diese Spalte in Richtung auf die Scheibenmitte zusätzlich mit einer Dichtungsmasse 5 aus Silikon-Kautschuk abgedichtet sind.The glass door 1 shown in the drawing is part of a fire protection glazing, of which two
Die über ein Scharnier 6 schwenkbar an der Brandschutzverglasung gelagerte Glastür 1 besteht ebenfalls aus einer Brandschutzscheibe 2b, die in der bereits beschriebenen Weise an ihren Rändern durch einen Türrahmen 7 gehalten ist, der sich aus den Hohlprofilen 3 und einem Türprofil 8 an der Stirnseite der Brandschutzscheibe 2b zusammensetzt. An den der Scharnierseite gegenüberliegenden Hohlprofilen 3 ist jeweils eine Türklinke 8a zur Betätigung eines nicht dargestellten Verriegelungsmechanismus angebracht.The glass door 1, which is pivotably mounted on the fire protection glazing via a
Die Brandschutzscheiben 2a, 2b bestehen aus einem Spezialverbundglas, welches aus mehreren Glasscheiben mit dazwischen angeordneten Brandschutzschichten besteht. Im Brandfall werden diese Brandschutzschichten aktiviert, wobei sie Wärmestrahlung absorbieren und so eine wirksame Dämmschicht bilden, welche den Durchgang von Feuer und Rauch verhindert. Dabei führt die Aktivierung der Brandschutzschichten im Brandfall dazu, daß diese aufschäumen und eine Trübung annehmen, so daß praktisch eine undurchsichtige Feuerschutzwand entsteht.The
Zur Halterung der Glastür 1 innerhalb der Brandschutzverglasung ist die Glastür 1 an ihren senkrechten Kanten jeweils mit dem Türprofil 8 versehen, welches an den Stirnseiten der Hohlprofile 3 der Glastür 1 befestigt ist und gemeinsam mit den entsprechenden beiden Hohlprofilen 3 den Türrahmen 7 der Glastür bildet. Die Türprofile 8 liegen bei geschlossener Glastür 1 über Dichtungen 9 an ebenfalls flachen Zargenprofilen 10 an, die an entsprechenden Stirnflächen der Hohlprofile 3 der Brandschutzverglasung befestigt sind. Die Türprofile 8 des Türrahmens 7 sowie die Zargenprofile 10 sind zwar als Flachprofile ausgebildet; dies schließt jedoch nicht aus, daß beide Profile über Abwinklungen 11, 12 verfügen, wobei die Abwinklungen 11 zur dichtenden Anlage der Glastür 1 in geschlossenem Zustand dienen, während die Abwinklung 12 die Verbindung zwischen einem der Türprofile 8 und dem als Zapfenband ausgebildeten Scharnier 6 herstellt.To hold the glass door 1 within the fire protection glazing, the glass door 1 is provided on its vertical edges with the
In der Zeichnung ist dargestellt, daß zwischen den den jeweiligen Brandschutzscheiben 2a, 2b zugewandten Flächen der Türprofile 8 bzw. der Zargenprofile 10 und den benachbarten Stoßflächen 13a bzw. 13b der Brandschutzscheiben 2a bzw. 2b eine Fuge 14 mit einer Fugenbreite f von höchstens 6mm verbleibt. Beim Ausführungsbeispiel beträgt die Fugenbreite f der Fuge 14 weniger als 4mm. Hierzu sind die flachen Zargenprofile 10 sowie Türprofile 8 im Bereich der Stoßflächen 13a bzw. 13b leicht in Richtung zur jeweiligen Scheibe hin eingesenkt.In the drawing it is shown that between the respective
Im Brandfall wird infolge der Erhitzung der Brandschutzscheiben 2a, 2b die darin befindliche Brandschutzschicht aufgeschäumt, wobei Material dieses Schaumes aus den Stoßflächen 13a, 13b der Brandschutzscheiben 2a, 2b austritt und die Fugen 14 verschließt, so daß Flammen und Rauch nicht mehr durch die Fugen 14 hindurchgelangen können. Darüber hinaus bewirkt der aus den Stoßflächen 13a, 13b austretende Schaum eine Kühlung des anliegenden Zargenprofils 10 bzw. Türprofils 8, so daß der Übergang von Wärme über die Zargenprofile 10 bzw. Türprofile 8 erschwert wird. Durch die beschriebene Wirkungsweise der Brandschutzscheiben 2a, 2b wird also nicht nur der Übergang von Flammen und Rauch durch die Fugen 14 verhindert, sondern zusätzlich die konstruktionsbedingte Wirkung der Zargenprofile 10 und Türprofile 8 als Wärmebrücken auf ein Mindestmaß reduziert. Dieser Vorteil einer Kühlung der Zargenprofile 10 bzw. Türprofile 8 wird dadurch erreicht, daß diese Profile hinreichend flach ausgebildet sind, so daß die Kühlwirkung des aus den Stoßflächen 13a, 13b austretenden Schaumes den gesamten, als potentielle Wärmebrücke in Betracht kommenden Querschnitt der Zargenprofile 10 und Türprofile 8 erfaßt. In der Einsenkung des Zargenprofils 10 ist ein Streifen 15 aus im Brandfall aufschäumendem Material befestigt.
