Abstract
Description
Die Erfindung betrifft eine mehrscheibige Brandschutzverglasung, bei der wenigstens eine Scheibe eine feuerwiderstandsfähige oder feuerhemmende Glasscheibe ist, die unter Zwischenschaltung eines Luftzwischenraums über einen hohlen, mit einem feuchtigkeitsabsorbierenden Mittel gefüllten metallischen Abstandrahmen mit einer weiteren Glasscheibe am Rand dicht verbunden ist und die mit einer Druckausgleichsvorrichtung versehen ist.The invention relates to a multi-pane Fire protection glazing with at least one pane is fire-resistant or fire-retardant glass, with the interposition of an air gap a hollow one with a moisture absorbent filled metal spacer with another Glass pane is tightly connected at the edge and with a Pressure compensation device is provided.
Während Brandschutzgläser für die Anwendung im Innenbereich von Gebäuden in der Regel einschalig ausgebildet sind, werden sie normalerweise zweischalig ausgeführt, wenn sie in der Außenhaut von Gebäuden eingesetzt werden. Das ist nämlich immer dann erforderlich, wenn die Verglasung einen hohen Wärmedämmwert aufweisen soll, wie er meist nur-durch einen zwei- oder mehrschaligen Aufbau in der Art der üblichen Isoliergläser zu erreichen ist.While fire protection glasses for indoor use buildings are usually single-shell, they are usually double-skinned if they are can be used in the outer skin of buildings. This is namely always necessary when the glazing is one should have a high thermal insulation value, as it usually only through a two- or multi-layer structure in the manner of usual insulating glass can be reached.
Im Brandfall und insbesondere auch bei der normgerechten Prüfung der Brandschutzverglasung führt die verhältnismäßig schnelle Aufheizung nach der sogenannten Einheitstemperaturkurve, bei der die Temperatur innerhalb von 5 Minuten auf 650° C ansteigt, bei Brandschutzgläsern mit dem Aufbau von Isolierglasscheiben zu einer starken Ausdehnung des Luft- bzw. Gasvolumens im Zwischenraum der Verglasung. Da der Zwischenraum am Rand hermetisch abgedichtet ist, führt die Ausdehnung des Glasvolumens zu einer starken Erhöhung des Drucks im Scheibenzwischenraum. Dieser erhöhte Innendruck kann zur Folge haben, daß die Randabdichtung zerstört wird, was einen nachteiligen Einfluß auf die Brandschutzwirkung der Verglasung haben kann. Außerdem werden die Glasscheiben, in denen sich unter der Temperatureinwirkung bereits starke Zugspannungen im Randbereich ausgebildet haben, durch den erhöhten Innendruck zusätzlichen Biegebelastungen ausgesetzt. Die sich einander überlagernden mechanischen Spannungen können leicht die Festigkeit einer Glasscheibe überschreiten, so daß sie vorzeitig zerbricht. Damit ist die gewünschte Feuerwiderstandsfähigkeit nicht immer gegeben.In the event of a fire, and especially when it comes to standards Checking the fire protection glazing leads the proportionately rapid heating after the so-called Unit temperature curve at which the temperature is within increases from 5 minutes to 650 ° C for fire protection glasses with the construction of insulating glass panes to a strong Expansion of the air or gas volume in the space between Glazing. Because the space on the edge is hermetic is sealed, the expansion of the glass volume leads to a sharp increase in pressure in the space between the panes. This increased internal pressure can result in the Edge seal is destroyed, which is a disadvantage Have an influence on the fire protection effect of the glazing can. In addition, the glass panes, which are under the temperature influence already strong tensile stresses in the Have formed edge area by the raised Internal pressure exposed to additional bending loads. The overlapping mechanical stresses can easily exceed the strength of a sheet of glass, so that it breaks prematurely. This is the one you want Fire resistance is not always given.
Es ist deshalb bekannt, Brandschutzscheiben bei mehrschaliger Ausführung mit einer Druckausgleichsvorrichtung zu versehen. So ist es aus der EP 0114551 B1 bekannt, eine der Glasscheiben mit einer Bohrung zu versehen und diese Bohrung mit einem Stopfen aus Woodschem Metall zu verschließen. Das Woodsche Metall soll bei einer Temperatur zwischen 70 und 150° C schmelzen und dadurch die Öffnung freigeben.It is therefore known to use fire protection panes multi-layer design with one To provide pressure compensation device. So it is from the EP 0114551 B1 known, one of the glass panes with a Provide bore and this bore with a plug Lock Woodschem metal. Wood's metal should melt at a temperature between 70 and 150 ° C and thereby opening the opening.
Die Anbringung einer Bohrung in einer der Glasscheiben kann unter dem Gesichtspunkt der Herstellung der Bohrung wie auch unter dem Gesichtspunkt einer Schwächung der Glasscheibe nachteilig sein. Aus diesem Grund wird in der EP 0569298 A1 vorgeschlagen, einen Stopfen aus Woodschem Metall nicht in einer Glasscheibe, sondern im Eckbereich des metallischen Abstandsrahmens anzuordnen.It is possible to make a hole in one of the glass panes from the point of view of making the bore like also from the point of view of weakening the Glass pane may be disadvantageous. For this reason, in the EP 0569298 A1 proposed a stopper made from Woodschem Metal not in a glass pane, but in the corner area to arrange the metallic spacing frame.
Bei diesen bekannten Lösungen stellen die Stopfen aus Woodschem Metall Schmelzventile dar, die die Öffnung freigeben, wenn beim Brand oder beim Brandversuch der Bereich der Glasscheibe, in dem das Schmelzventil angeordnet ist, die Schmelztemperatur des Metalls erreicht hat. Da aber der betreffende Bereich dann schon eine Temperatur von mehr als 70° C aufweisen muß, weist die dem Feuer ausgesetzte Glasscheibe in vielen Fällen insgesamt schon noch höhere Temperaturen auf, die dann bereits hohe Spannungen in das Glas induzieren können, die die Festigkeit des Glases überschreiten. Das bedeutet, daß die betreffende Glasscheibe bereits zerbrochen sein kann, bevor die Druckausgleichsbohrung frei wird.In these known solutions, the plugs are turned off Woodschem metal melting valves that represent the opening release if the Area of the glass pane in which the melting valve is arranged, the melting temperature of the metal is reached Has. But since the area in question is already one Must have temperature of more than 70 ° C, has the Glass pane exposed to fire in many cases as a whole even higher temperatures, which are already high Can induce stresses in the glass that the Exceed the strength of the glass. That means that Glass pane in question may already have broken before the pressure equalization hole becomes free.
Eine aus einem Kapillarrohr bestehende Druckausgleichsvorrichtung, dessen eines Ende in dem feuchtigkeitsabsorbierenden Trockenmittel innerhalb des metallischen Abstandrahmens endet und dessen anderes Ende durch die Wand des Abstandrahmens und durch die Randabdichtung der Isolierglasscheibe nach außen geführt ist und mit der Umgebungsatmosphäre in Verbindung steht, ist in der US-A-3.771.276 für eine als Lärmschutzverglasung ausgebildete Isolierglasscheibe beschrieben. Diese Druckausgleichsvorrichtung dient dazu, Druckbelastungen der Glasscheiben zu verhindern, die auf atmosphärischen Luftdruckschwankungen beruhen, und die wegen des verhältnismäßig großen Gasvolumens bei Lärmschutzgläsern höhere Werte annehmen können als bei normalen Isolierglasscheiben. Atmosphärische Luftdruckschwankungen entwickeln sich jedoch langsam und erreichen in der Regel auch keine Werte, die eine Bruchgefahr für die Glasscheiben bedeuten.One consisting of a capillary tube Pressure compensation device, one end of which in the moisture absorbing desiccant within the metallic spacer ends and the other end through the wall of the spacer frame and through the Edge sealing of the insulating glass pane led to the outside and is connected to the surrounding atmosphere, is in US-A-3,771,276 for as noise protection glazing trained insulating glass pane described. This Pressure equalization device serves to relieve pressure on the Prevent glass panes that are on atmospheric Air pressure fluctuations are based on the relatively large gas volume in noise protection glass can assume higher values than normal ones Insulating glass panes. Atmospheric fluctuations in air pressure however, develop slowly and usually reach also no values that could break the glass panes mean.
Der Erfindung liegt die Aufgabe zugrunde, ein Brandschutz-Isolierglas mit einer Druckausgleichsvorrichtung zu versehen, die die Nachteile der für diesen Zweck bei Brandschutzgläsern bekannten Lösungen, nämlich Beeinträchtigung des Sichtfeldes und/oder Verwendung von Blei und Cadmium enthaltenden niedrigschmelzenden Metallen, nicht aufweist.The invention has for its object a fire protection insulating glass with a pressure compensation device provided that the disadvantages of for this purpose Fire protection glasses known solutions, namely Impairment of the field of vision and / or use of Low melting metals containing lead and cadmium, does not have.
Die Erfindung besteht darin, daß eine bei Isolierglasscheiben aus zwei unter Zwischenschaltung eines Luftzwischenraums über einen hohlen, mit einem feuchtigkeitsabsorbierenden Mittel gefüllten metallischen Abstandrahmen am Rand dicht miteinander verbundenen Glasscheiben bekannte Druckausgleichsvorrichtung, die ein metallisches Kapillarrohr umfaßt, dessen eines Ende in dem innerhalb des metallischen Abstandrahmens angeordneten feuchtigkeitsabsorbierenden Trockenmittel endet, und dessen anderes Ende durch die Wand des Abstandrahmens und durch die Randabdichtung der Isolierglasscheibe nach außen geführt ist und im eingebauten Zustand mit der Umgebungsatmosphäre in Verbindung steht, bei einer mehrscheibigen Brandschutzverglasung, bei der wenigstens eine Scheibe eine feuerwiderstandsfähige oder feuerhemmende Glasscheibe ist, als Druckausgleichsvorrichtung für den im Brandfall im Luftzwischenraum entstehenden Überdruck angewendet wird, wobei das metallische Kapillarrohr einen Innendurchmesser von 0,1 bis 1 mm und eine Länge von wenigstens 30 cm, und vorzugsweise von 40 bis 100 cm aufweist.The invention is that a Insulating glass panes made of two with the interposition of one Air gap over a hollow, with one moisture absorbent filled metallic Spacer known at the edge tightly interconnected glass panes Pressure compensation device, which is a metallic Capillary tube, one end of which in the inside of the arranged metallic spacing frame moisture absorbing desiccant ends, and its other end through the wall of the spacer frame and through the edge seal of the insulating glass pane to the outside is guided and in the installed state with the Ambient atmosphere communicates at a multi-pane fire protection glazing, at least a pane a fire resistant or fire retardant Glass pane is used as a pressure compensation device for the Fire in the air gap creates excess pressure is applied, the metallic capillary tube a Inner diameter of 0.1 to 1 mm and a length of at least 30 cm, and preferably from 40 to 100 cm having.
Es hat sich gezeigt, daß eine derartige Druckausgleichsvorrichtung überraschenderweise auch in der Lage ist, den im Brandfall sehr schnell entstehenden hohen Überdruck im Scheibenzwischenraum schnell genug abzubauen, um jeden dadurch bedingten Bruch einer Glasscheibe sicher zu vermeiden. Da ein solches Kapillarrohr, wie man weiß, unter den genannten Bedingungen auch eine ausreichende Abdichtung gegen eindringende Luftfeuchtigkeit darstellt und auch für den Druckausgleich der atmosphärischen Druckschwankungen sorgt, entspricht ein erfindungsgemäß ausgebildetes Brandschutzglas auch unter diesen Gesichtspunkten allen Anforderungen.It has been shown that such Pressure equalization device surprisingly also in the It is able to withstand the high levels that arise very quickly in the event of fire Relieve excess pressure in the space between the panes quickly enough for any resulting breakage of a pane of glass to avoid. As such a capillary tube is known to sufficient under the conditions mentioned Represents sealing against penetrating air humidity and also for pressure equalization of the atmospheric Provides pressure fluctuations corresponds to an invention trained fire protection glass also under these Aspects all requirements.
Länge und Durchmesser des Kapillarrohres richten sich weitgehend nach der Größe der Brandschutzverglasung, das heißt nach dem Gasvolumen des Scheibenzwischenraums. Für übliche Scheibenabmessungen haben sich Kapillarrohre mit einer Länge von etwa 60 cm und einem Innendurchmesser von 0,2 bis 0,4 mm bewährt.The length and diameter of the capillary tube are aligned largely according to the size of the fire protection glazing is called after the gas volume of the space between the panes. For Capillary tubes have the usual disc dimensions a length of about 60 cm and an inside diameter of Proven 0.2 to 0.4 mm.

Die Brandschutzverglasung hat grundsätzlich den Aufbau
einer zweischeibigen Isolierverglasung, wobei jedoch
wenigstens eine der beiden Scheiben aus einer Glasscheibe
mit erhöhter Feuerwiderstandsfähigkeit besteht. Bei der
hier dargestellten Ausführungsform ist die Scheibe 1 eine
Verbundglasscheibe aus zwei Floatglasscheiben 2, 3 und
einer im Brandfall aufschäumenden Zwischenschicht 4,
beispielsweise aus Natriumsilikat, während die andere
Scheibe 5 beispielsweise aus einer thermisch vorgespannten
Glasscheibe besteht. Die beiden Scheiben 1 und 5 sind in
der bei Isolierglasscheiben üblichen Weise über einen
metallischen Abstandhalter 6 in Form eines Rechteckrohres
aus Stahl oder Aluminium miteinander verbunden. Die
Verbindung des Abstandrahmens 6 mit den beiden Scheiben 1
und 5 erfolgt über Klebeschichten 7 aus Butyl. Die
Hohlkehle zwischen dem Abstandrahmen 6 und den Innenflächen
der Randbereiche der beiden Scheiben 1 und 5 ist mit einer
zweiten Klebedichtmasse 8, insbesondere mit einer Silikon-
oder Polysulfidmasse, ausgefüllt.Fire protection glazing basically has the structure
double glazing, however
at least one of the two panes from a glass pane
with increased fire resistance. In the
The embodiment shown here is the
Der Abstandrahmen 6 ist mit einem
feuchtigkeitsabsorbierenden Granulat 10 gefüllt und ist auf
der dem Luftzwischenraum zugewandten Seite mit schmalen
Durchbrüchen 11 oder mit einem durchgehenden Schlitz
versehen. Die Durchbrüche 11 erlauben den Gasaustausch
zwischen dem Luftzwischenraum und dem mit dem
feuchtigkeitsabsorbierenden Granulat 10 gefüllten Hohlraum
des Abstandrahmens 6.The
In dem Abstandrahmen 6, der im vorliegenden Fall ein
rechteckiger Rahmen mit vier geraden Seiten ist, ist auf
einer Seite in dem mit dem Granulat 10 gefüllten Hohlraum
des Rahmenprofils ein Kapillarrohr 12 angeordnet. Das
Kapillarrohr 12 wird vor dem Einbringen der Klebedichtmasse
8 durch eine in der äußeren Wand in der Ecke des
Abstandrahmens 6 angebrachte Bohrung 13 in den mit dem
Granulat 10 gefüllten Abstandrahmen so weit
hineingeschoben, daß das Ende des Kapillarrohres um einige
Millimeter über die Umfangsfläche 14 der Verglasung
übersteht. Das Kapillarrohr 12 besteht vorzugsweise aus
nichtrostendem Stahl. Es hat einen Außendurchmesser von
etwa 1 mm und einen Innendurchmesser von etwa 0,25 mm. Die
Länge L des Kapillarrohres 12 beträgt etwa 60 cm, was sich
für Brandschutzgläser von etwa 1 m2 Flächengröße als
ausreichend erwiesen hat. Beim Abdichten der Verglasung mit
der Klebedichtmasse 8 und beim späteren Einsetzen der
Verglasung in den Rahmen muß selbstverständlich darauf
geachtet werden, daß die Öffnung des Kapillarrohres 12 frei
bleibt, so daß auch im eingebauten Zustand der
Brandschutzverglasung der Luftaustausch durch das
Kapillarrohr hindurch möglich bleibt.In the
Bei Ausdehnung des Luftvolumens des Scheibenzwischenraums
im Brandfall strömt mit zunehmendem Innendruck die Luft
durch die Durchbrüche 11 in den Hohlraum des Abstandrahmens
6 und von dort durch das Kapillarrohr 12 in die
Außenatmosphäre. Obwohl der Druckausgleich auf diese Weise
ermöglicht wird, wird durch die gewählte Anordnung
verhindert, daß sich die Luft im Scheibenzwischenraum in
unzulässiger Weise mit Feuchtigkeit anreichert.With expansion of the air volume of the space between the panes
in the event of a fire, the air flows with increasing internal pressure
through the
Es hat sich gezeigt, daß bei Brandschutzverglasungen bis zu Flächenabmessungen von etwa 1 m2 die Anordnung eines Kapillarrohres ausreicht. Bei größeren Flächenabmessungen kann es sich empfehlen, an einer anderen Ecke der Verglasung ein weiteres Kapillarrohr, oder gegebenenfalls auch ein drittes oder viertes Kapillarrohr vorzusehen.It has been shown that the arrangement of a capillary tube is sufficient for fire protection glazing up to surface dimensions of approximately 1 m 2 . In the case of larger surface dimensions, it may be advisable to provide a further capillary tube at another corner of the glazing, or possibly also a third or fourth capillary tube.
