Definitions
- the invention relates to a multi-pane fire protection glazing in which at least one pane is a fire-resistant or fire-retardant glass pane which, with the interposition of an air gap, is tightly connected to a further glass pane at the edge via a hollow metallic spacer frame filled with a moisture-absorbing agent and which is provided with a pressure compensation device is.
- fire protection glasses for indoor use are usually designed with one layer, they are usually made with two layers if they are used in the outer skin of buildings. This is always necessary if the glazing is to have a high thermal insulation value, which can usually only be achieved with a double or multi-layer structure in the manner of the usual insulating glass.
- the plugs made of Woodschem metal are melting valves which open the opening when the area of the glass pane in which the melting valve is arranged has reached the melting temperature of the metal during a fire or during a fire test.
- the area in question must then already have a temperature of more than 70 ° C.
- the invention is therefore based on the object of providing a fire protection insulating glass with a pressure compensation device which prevents the occurrence of a dangerous excess pressure in the space between the panes. Furthermore, the pressure compensation device should not impair the field of view of the glazing. Finally, the manufacture of fire protection insulating glazing should not be made significantly more difficult by the arrangement of the pressure compensation device.

- the length and diameter of the capillary tube largely depend on the size of the fire protection glazing, i.e. on the gas volume of the space between the panes.
- Capillary tubes with a length of about 60 cm and an inner diameter of 0.2 to 1 mm have proven their worth for common disc dimensions. Particularly satisfactory results are achieved with capillary tubes with an inner diameter of 0.2 to 0.4 mm.
- the fire protection glazing basically has the structure of double-pane insulating glazing, but at least one of the two panes consists of a glass pane with increased fire resistance.
- the pane 1 is a laminated glass pane composed of two float glass panes 2, 3 and an intermediate layer 4 which foams up in the event of a fire, for example made of sodium silicate, while the other pane 5 is made of a thermally toughened layer, for example Glass pane exists.
- the two panes 1 and 5 are connected to one another in the manner customary in insulating glass panes via a metallic spacer 6 in the form of a rectangular tube made of steel or aluminum.
- the spacer frame 6 is connected to the two panes 1 and 5 via adhesive layers 7 made of butyl.
- the fillet between the spacer frame 6 and the inner surfaces of the edge areas of the two panes 1 and 5 is filled with a second adhesive sealing compound 8, in particular with a silicone or polysulfide compound.

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 Abstandsrahmen 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 in which at least one pane is a fire-resistant or fire-retardant glass pane which, with the interposition of an air gap, is tightly connected to a further glass pane at the edge via a hollow metallic spacer frame filled with a moisture-absorbing agent and which is provided with a pressure compensation device is.
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 are usually designed with one layer, they are usually made with two layers if they are used in the outer skin of buildings. This is always necessary if the glazing is to have a high thermal insulation value, which can usually only be achieved with a double or multi-layer structure in the manner of the usual insulating glass.
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 in particular when testing the fire protection glazing in accordance with the standards, the relatively rapid heating up according to the so-called standard temperature curve, at which the temperature rises to 650 ° C within 5 minutes, leads to a strong expansion of the air or Volume of gas in the space between the glazing. Since the space at the edge is hermetically sealed, the expansion of the glass volume leads to a sharp increase in the pressure in the space between the panes. This increased internal pressure can result in the edge seal being destroyed, which has an adverse effect on the fire protection effect of the glazing can. In addition, the glass panes, in which strong tensile stresses have already formed in the edge region under the influence of temperature, are exposed to additional bending loads due to the increased internal pressure. The overlapping mechanical stresses can easily exceed the strength of a glass pane so that it breaks prematurely. The desired fire resistance is not always guaranteed.
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 provide fire protection panes with a multi-layer design with a pressure compensation device. It is known from EP 0114551 B1 to provide one of the glass panes with a bore and to close this bore with a stopper made of Wood's metal. Wood's metal should melt at a temperature between 70 and 150 ° C and thereby open 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.The drilling of a hole in one of the glass panes can be disadvantageous from the point of view of producing the hole as well as from the point of view of weakening the glass pane. For this reason it is proposed in EP 0569298 A1 to arrange a stopper made of Wood's metal not in a glass pane but in the corner area of the metallic spacer 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 made of Woodschem metal are melting valves which open the opening when the area of the glass pane in which the melting valve is arranged has reached the melting temperature of the metal during a fire or during a fire test. However, since the area in question must then already have a temperature of more than 70 ° C., the glass pane exposed to fire in many cases already has altogether higher temperatures, which can then induce high stresses in the glass, which increase the strength of the glass exceed. That means that The glass pane in question may already have broken before the pressure compensation hole becomes free.
Der Erfindung liegt infolgedessen die Aufgabe zugrunde, ein Brandschutz-Isolierglas mit einer Druckausgleichsvorrichtung zu versehen, die die Entstehung eines gefährlichen Überdrucks im Scheibenzwischenraum verhindert. Ferner soll die Druckausgleichsvorrichtung das Sichtfeld der Verglasung nicht beeinträchtigen. Schließlich soll die Herstellung einer Brandschutz-Isolierverglasung durch die Anordnung der Druckausgleichsvorrichtung nicht wesentlich erschwert werden.The invention is therefore based on the object of providing a fire protection insulating glass with a pressure compensation device which prevents the occurrence of a dangerous excess pressure in the space between the panes. Furthermore, the pressure compensation device should not impair the field of view of the glazing. Finally, the manufacture of fire protection insulating glazing should not be made significantly more difficult by the arrangement of the pressure compensation device.
Die erfindungsgemäße Brandschutzverglasung zeichnet sich dadurch aus, daß in dem metallischen Abstandsrahmen ein wenigstens etwa 30 cm langes metallisches Kapillarrohr angeordnet ist, dessen eines Ende in dem feuchtigkeitsabsorbierenden Trockenmittel endet und dessen anderes Ende durch die Wand des Abstandsrahmens und durch die Randabdichtung hindurch nach außen geführt ist und im eingebauten Zustand der Brandschutzverglasung mit der Umgebungsatmosphäre in Verbindung steht.The fire protection glazing according to the invention is characterized in that an at least about 30 cm long metallic capillary tube is arranged in the metallic spacer frame, one end of which ends in the moisture-absorbing drying agent and the other end of which is led out through the wall of the spacer frame and through the edge seal and is connected to the ambient atmosphere when the fire protection glazing is installed.
Es hat sich gezeigt, daß die erfindungsgemäße Anordnung eines Kapillarrohres innerhalb des Abstandsrahmens ausreicht, um bereits bei einem verhältnismäßig niedrigen Überdruck im Scheibenzwischenraum den Druck abzubauen und das Entstehen eines gefährlichen Überdrucks sicher zu vermeiden. Andererseits hat es sich gezeigt, daß ein solches Kapillarrohr, wenn es die genannte Mindestlänge aufweist, eine ausreichende Abdichtung gegen eindringende Luftfeuchtigkeit darstellt. Infolge des geringen Innendurchmessers des Kapillarrohres findet nämlich ein Luftaustausch durch die Kapillare hindurch nur in außerordentlich geringem Umfang statt. Bei Druckschwankungen bewegt sich vielmehr die Luftsäule in dem Kapillarrohr als ganze, und ein geringfügiger Austausch der Luft zwischen dem Scheibenzwischenraum und der Außenatmosphäre findet erst statt, wenn die gesamte Luftsäule des Kapillarrohres aus dem Kapillarrohr verdrängt ist. Das reicht aus, um bei den normalen atmosphärischen Druckschwankungen ein übermäßiges Eindringen von Feuchtigkeit in den Luftzwischenraum zu vermeiden.It has been shown that the arrangement according to the invention of a capillary tube within the spacing frame is sufficient to reduce the pressure in the space between the panes even at a relatively low excess pressure and to reliably avoid the occurrence of a dangerous excess pressure. On the other hand, it has been shown that such a capillary tube, if it has the minimum length mentioned, represents a sufficient seal against the ingress of atmospheric moisture. Because of the small inside diameter of the capillary tube, an exchange of air through the capillary takes place only to an extremely small extent. In the case of pressure fluctuations, the air column moves in the capillary tube as a whole, and a slight exchange of the Air between the space between the panes and the outside atmosphere only takes place when the entire air column of the capillary tube has been displaced from the capillary tube. This is sufficient to prevent excessive moisture penetration into the air gap during normal atmospheric pressure fluctuations.
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 1 mm bewährt. Besonders zufriedenstellende Ergebnisse werden mit Kapillarrohren mit einem Innendurchmesser von 0,2 bis 0,4 mm erzielt.The length and diameter of the capillary tube largely depend on the size of the fire protection glazing, i.e. on the gas volume of the space between the panes. Capillary tubes with a length of about 60 cm and an inner diameter of 0.2 to 1 mm have proven their worth for common disc dimensions. Particularly satisfactory results are achieved with capillary tubes with an inner diameter of 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 Abstandshalter 6 in Form eines Rechteckrohres aus Stahl oder Aluminium miteinander verbunden. Die Verbindung des Abstandshalterahmens 6 mit den beiden Scheiben 1 und 5 erfolgt über Klebeschichten 7 aus Butyl. Die Hohlkehle zwischen dem Abstandsrahmen 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.The fire protection glazing basically has the structure of double-pane insulating glazing, but at least one of the two panes consists of a glass pane with increased fire resistance. In the embodiment shown here, the
Der Abstandsrahmen 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 Abstandshalters 6.The
In dem Abstandshalter 6, der im vorliegenden Fall ein rechteckiger Rahmen mit vier geraden Seiten ist, ist auf einer Seite in dein 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 Abstandsrahmens 6 angebrachte Bohrung 13 in den mit dem Granulat 10 gefüllten Abstandshalter 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 der Kapillare 12 frei bleibt, so daß auch im eingebauten Zustand der Brandschutzverglasung der Luftaustausch durch die Kapillare 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 Abstandhalters 6 und von dort durch die Kapillare 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.When the air volume of the inter-pane space expands 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, or possibly also a third or fourth capillary tube, at another corner of the glazing.
