Description

Die Erfindung betrifft eine Brandschutzglas-Einheit mit einer Glasscheibe und einem Metallrahmen mit umlaufender Aufnahmenut.The invention relates to a fire protection glass unit with a glass pane and a metal frame with a circumferential receiving groove.

Bei der bekannten Brandschutzglas-Einheit, von der die Er­findung ausgeht (DE-PS 23 28 737, DE-OS 31 40 785), endet der Rand der Glasscheibe in der Aufnahmenut. Zumindest auf der der Hitzeeinwirkung abgewandten Seite befindet sich zwischen der Glasscheibe und dem Flansch der Aufnahmenut eine Isolierstoffeinlage. Auf der der Hitzeeinwirkung zu­gewandten Seite fehlt bei einer der bekannten Ausführungs­formen die Isolierstoffeinlage, um den Temperatur­gradienten zwischen der der Hitzeeinwirkung ausgesetzten Hauptfläche der Glasscheibe und dem Rand der Glasscheibe klein zu halten und störenden Wärmespannungen entgegenzu­wirken. Die bekannten Maßnahmen befriedigen möglicher­weise, wenn die Hitzeeinwirkung nur verhältnismäßig kurz­zeitig stattfindet, genügen jedoch den Anforderungen eines Langzeitbrandschutzes, der z. B. für 60 Minuten oder länger wirksam bleiben soll, nicht. Auch kommt es vor, daß die Glasscheibe sich in ihrem Randbereich durch Erwärmung verformt und die Glasscheibe bereichsweise aus der Auf­nahmenut freikommt und wegschmilzt.In the known fire protection glass unit from which the invention is based (DE-PS 23 28 737, DE-OS 31 40 785), the edge of the glass pane ends in the receiving groove. At least on the side facing away from the heat there is an insulating material insert between the glass pane and the flange of the receiving groove. On the side facing the heat, the insulating material insert is missing in one of the known embodiments in order to keep the temperature gradient between the main surface of the glass plate exposed to the heat and the edge of the glass plate small and to counteract disturbing thermal stresses. The known measures may satisfy if the heat takes place only for a relatively short time, but meet the requirements of long-term fire protection, which, for. B. should remain effective for 60 minutes or longer, not. It also happens that the glass pane deforms in its edge region by heating and the glass pane in some areas comes out of the receiving groove and melts away.

Der Erfindung liegt die Aufgabe zugrunde, eine Brand­schutzglas-Einheit des eingangs beschriebenen grundsätz­lichen Aufbaus zu schaffen, die für den Langzeitbrand­schutz geeignet ist und bei der die Glasscheibe im Brand­fall in sicherer Verbindung mit dem Metallrahmen bleibt.The invention has for its object to provide a fire protection glass unit of the basic structure described above, which is suitable for long-term fire protection and in which the glass pane remains in safe connection with the metal frame in the event of fire.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß der Rand der Glasscheibe vor dem Metallrahmen endet, daß an den Rand der Glasscheibe ein Ausgleichsadapter angeschlos­sen ist, der zwei auf den Randbereich der Glasscheibe auf­geklebte metallische Adapterstreifen aufweist und mit Überständen der Adapterstreifen in die Aufnahmenut ein­faßt, und daß zwischen den Überständen ein leistenförmiger nichtmetallischer Abstandshalter angeordnet ist. Es ver­steht sich, daß der Kleber, mit dem erfindungsgemäß ge­arbeitet wird, ein ausreichend temperaturbeständiger Kleber ist, beispielsweise ein Kitt oder Kleber auf Wasserglasbasis oder Silikonbasis. Insbesondere im Rand­bereich des Ausgleichsadapters, zur Glasscheibe hin, empfiehlt sich aus Abdichtungsgründen die Anordnung eines Klebers auf Silikonbasis. Es empfiehlt sich, den Kleber, z. B. durch feinteilige metallische Zusätze, gut wärme­leitend einzurichten. Insbesondere kann mit Mehrkompo­nentenklebern gearbeitet werden, die keiner Trocknung be­dürfen.To achieve this object, the invention teaches that the edge of the glass pane ends in front of the metal frame, that a compensating adapter is connected to the edge of the glass pane, which has two metallic adapter strips glued to the edge region of the glass pane and that fits into the receiving groove with projections of the adapter strips, and that a strip-shaped non-metallic spacer is arranged between the protrusions. It goes without saying that the adhesive with which the invention is used is a sufficiently temperature-resistant adhesive, for example a cement or adhesive based on water glass or silicone. In particular in the edge area of the compensation adapter, towards the glass pane, it is advisable to arrange a silicone-based adhesive for sealing reasons. It is recommended to use the adhesive, e.g. B. by fine-particle metallic additives to set up good thermal conductivity. In particular, multi-component adhesives can be used that do not require drying.

Der Ausgleichsadapter stellt bei der erfindungsgemäßen Brandschutzglas-Einheit zunächst sicher, daß im Brandfall zwischen der großen Fläche der Glasscheibe und dem Rand der Glasscheiben ein störender Temperaturgradient nicht entsteht. Der Ausgleichsadapter funktioniert insoweit zu­nächst als Temperaturausgleichsadapter. Er wirkt aber außerdem mechanisch ausgleichend und verhindert, daß mechanische Spannungen aus unterschiedlicher Wärmedehnung im Metallrahmen und in der Glasscheibe sich negativ aus­ wirken. Darüber hinaus verbindet der Ausgleichsadapter die Glasscheibe sicher mit dem Metallrahmen, weil er in die Aufnahmenut des Metallrahmens einfaßt.The compensation adapter first ensures in the fire protection glass unit according to the invention that in the event of a fire, a disruptive temperature gradient does not arise between the large surface of the glass pane and the edge of the glass panes. In this respect, the compensation adapter initially functions as a temperature compensation adapter. But it also has a mechanical balancing effect and prevents mechanical stresses from different thermal expansion in the metal frame and in the glass pane from having a negative effect Act. In addition, the compensation adapter securely connects the glass pane to the metal frame because it fits into the receiving groove of the metal frame.

Im einzelnen bestehen mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung der erfindungsgemäßen Brand­schutzglas-Einheit. Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß auf die Adapter­streifen abdeckend Blechstreifen aufgeklebt sind. Diese Blechstreifen verhindern, daß freie Flammen unmittelbar mit dem Ausgleichsadapter bzw. dem Kleber in Verbindung kommen, bestehen jedoch aus einem so dünnen Blech, daß die beschriebenen Ausgleichsfunktionen des Ausgleichsadapters nicht beeinträchtigt werden. Um insbesondere die mecha­nische Ausgleichsfunktion stark einzuprägen, empfiehlt die Erfindung, daß zwischen dem Rand der Glasscheibe und dem Metallrahmen ein Abstandsbereich angeordnet ist, der z. B. der halben Dicke der Glasscheibe entspricht. Dabei kann der Abstandshalter in diesen Abstandsbereich hineinragen. Es empfiehlt sich zur Vermeidung von störenden Spannungen, zwischen dem Abstandshalter und dem Rand der Glasscheibe einen Spalt freizulassen, der z. B. eine Spaltweite von einigen Millimetern aufweist.There are several options for further training and design of the fire protection glass unit according to the invention. A preferred embodiment of the invention is characterized in that sheet metal strips are glued to cover the adapter strips. These metal strips prevent free flames from coming into direct contact with the compensating adapter or the adhesive, but consist of a sheet which is so thin that the compensating functions of the compensating adapter described are not impaired. In order to particularly impress the mechanical compensation function, the invention recommends that a spacing area is arranged between the edge of the glass pane and the metal frame, the z. B. corresponds to half the thickness of the glass sheet. The spacer can protrude into this spacing area. To avoid disturbing tensions, it is advisable to leave a gap between the spacer and the edge of the glass pane, which, for. B. has a gap width of a few millimeters.

Da erfindungsgemäß die Überstände der Adapterstreifen bzw. die Blechabdeckung auf den Überständen in die Aufnahmenut hineinragt, wird man im allgemeinen zwischen diesen Über­ständen bzw. der Blechabdeckung und dem Metallrahmen eine Isolierung aus einem geeigneten hitzebeständigen Material anordnen. Die Adapterstreifen bestehen, wie bereits er­ wähnt, aus verhältnismäßig dünnem Stahlblech. Die Adapter­streifen können als Streckmetallstreifen aber auch als flächige Metallbauteile ausgeführt sein, die auf einer Seite kleberverankernde Vorsprünge aufweisen. Die Adapter­streifen können auch als Drahtnetz ausgeführt sein. Die Blechstreifen aus Stahlblech würden regelmäßig eine Dicke aufweisen, die kleiner ist als 1 mm.Since, according to the invention, the protrusions of the adapter strips or the sheet metal cover protrude from the protrusions into the receiving groove, insulation made of a suitable heat-resistant material will generally be arranged between these protrusions or the sheet metal cover and the metal frame. The adapter strips, like him, exist thinks of relatively thin sheet steel. The adapter strips can be designed as expanded metal strips but also as flat metal components which have protrusions anchoring on one side. The adapter strips can also be designed as a wire mesh. The sheet metal strips from sheet steel would regularly have a thickness that is less than 1 mm.

Bei der erfindungsgemäßen Brandschutzglas-Einheit kann mit unterschiedlichen Glasscheiben gearbeitet werden. Bewährt hat sich eine Ausführungsform, bei der die Glasscheibe als Einscheiben-Sicherheitsglasscheibe ausgeführt ist. Die Glasscheibe kann aber auch als eine Borosilikat- oder Alumosilikatglasscheibe ausgeführt sein. Man kann aber auch eine Isolierglaseinheit als Glasscheibe einsetzen. Es versteht sich, daß in diesem Falle das Verbundmaterial entsprechend temperaturbeständig ausgeführt ist. Als Ab­standshalter eignet sich insbesondere eine Calcium-­Silikatleiste.In the fire protection glass unit according to the invention, different glass panes can be used. An embodiment has proven itself in which the glass pane is designed as a single-pane safety glass pane. However, the glass pane can also be designed as a borosilicate or aluminosilicate glass pane. But you can also use an insulating glass unit as a glass pane. It is understood that in this case the composite material is designed to be temperature-resistant. A calcium silicate strip is particularly suitable as a spacer.

Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Es zeigen in schematischer Darstellung

  • Fig. 2 eine Draufsicht auf eine Ecke einer solchen Brand­schutzglas-Einheit.
In the following, the invention will be explained in more detail with reference to a drawing showing only one embodiment. They show a schematic representation
  • Fig. 1 shows a section through a fire protection glass unit according to the invention, in sections and
  • Fig. 2 is a plan view of a corner of such a fire protection glass unit.

Die in den Figuren dargestellte Brandschutzglas-Einheit besteht in ihrem grundsätzlichen Aufbau aus einer Glas­scheibe 1 und einem Metallrahmen 2. Im Ausführungsbeispiel ist die Glasscheibe 1 eine Einscheiben-Sicherheitsglas­scheibe. Der Metallrahmen 2 besitzt eine umlaufende Auf­nahmenut 3.The basic structure of the fire protection glass unit shown in the figures consists of a glass pane 1 and a metal frame 2. In the exemplary embodiment, the glass pane 1 is a single pane safety glass pane. The metal frame 2 has a circumferential receiving groove 3.

Insbesondere aus der Fig. 1 entnimmt man, daß der Rand 4 der Glasscheibe 1 vor dem Metallrahmen 2 endet. An den Rand 4 der Glasscheibe 1 ist ein Ausgleichsadapter 5 ange­schlossen. Der Ausgleichsadapter 5 weist zwei auf den Randbereich der Glasscheibe 1 aufgeklebte metallische Adapterstreifen, im Ausführungsbeispiel in Form eines Streckgitterstreifens 6, auf und faßt mit Überständen 7 dieser Streckgitterstreifen 6 in die Aufnahmenut 3 ein. Zwischen den Überständen 7 befindet sich ein leisten­förmiger nichtmetallischer Abstandshalter 8. Im Ausfüh­rungsbeispiel sind auf die Streckgitterstreifen 6 ab­deckende Blechstreifen 9 aufgeklebt. Zwischen dem Rand 4 der Glasscheibe 1 und dem Metallrahmen 2 erkennt man einen Abstandsbereich 10, der etwa der halben Dicke der Glas­scheiben 1 entspricht. Der Abstandshalter 8 ragt in diesen Abstandsbereich 10 hinein, jedoch befindet sich zwischen dem Abstandshalter 8 und dem Rand 4 der Glasscheibe 1 ein Spalt 11 von einigen Millimetern.1 that the edge 4 of the glass pane 1 ends in front of the metal frame 2. A compensation adapter 5 is connected to the edge 4 of the glass pane 1. The compensating adapter 5 has two metallic adapter strips, glued to the edge region of the glass pane 1, in the exemplary embodiment in the form of an expanded metal strip 6, and includes protrusions 7 of these expanded metal strips 6 in the receiving groove 3. A strip-shaped, non-metallic spacer 8 is located between the projections 7. In the exemplary embodiment, sheet metal strips 9 covering the expanded metal strips 6 are glued on. Between the edge 4 of the glass pane 1 and the metal frame 2, a spacing area 10 can be seen, which corresponds to approximately half the thickness of the glass panes 1. The spacer 8 protrudes into this spacing area 10, but there is a gap 11 of a few millimeters between the spacer 8 and the edge 4 of the glass pane 1.

Zwischen den Überständen 7 bzw. den abdeckenden Blech­streifen 9 auf den Überständen 7 und dem Metallrahmen 2 ist eine Isolierung 12 angeordnet, die aus einem ge­eigneten temperaturbeständigen Material besteht. Die Streckgitterstreifen 6 mögen aus Stahlblech bestehen. Auch der Metallrahmen 2 ist im allgemeinen ein Stahlrahmen. Die Blechstreifen 9 sind vorzugsweise ebenfalls Stahlblech­streifen, ihre Dicke soll kleiner sein als 1 mm. Der Ab­standshalter 8 ist z. B. eine Calcium-Silikatleiste. Die Streckgitterstreifen 6 erlauben eine einfache und schnelle Trocknung des Klebers, bevor die Blechstreifen 9 aufge­bracht werden. Zugleich wird aber auch die Verklebung mit den Blechstreifen 9 verbessert. Außerdem halten die Streckgitterstreifen 6 das erweichte oder geschmolzene Glas im Brandfall sehr sicher fest. Die Kleber 13 sind, wie bereits erwähnt, ausreichend hitzebeständig. Wird mit einem Silikonkleber im Randbereich des Ausgleichsadapters 5 gearbeitet, so bewirkt dieses eine sichere Abdichtung gegen Feuchtigkeit und damit auch einen Wetterschutz. - Die Kleber 13 sind übliche Brandschutzkleber, beispiels­weise auf Wasserglasbasis oder auch auf Silikonbasis. Die Beimischung von Metallpulver ist möglich, um die Wärme­leitfähigkeit zu erhöhen. - Es versteht sich, daß man die den Ausgleichsadapter 5 bildenden Bauteile schon vor der Vereinigung mit der Glasscheibe 1 miteinander verbinden kann.Insulation 12, which consists of a suitable temperature-resistant material, is arranged between the protrusions 7 or the covering metal strips 9 on the protrusions 7 and the metal frame 2. The Expanded mesh strips 6 may consist of sheet steel. The metal frame 2 is also generally a steel frame. The metal strips 9 are preferably also steel strips, their thickness should be less than 1 mm. The spacer 8 is, for. B. a calcium silicate strip. The expanded metal strips 6 allow the adhesive to be dried easily and quickly before the metal strips 9 are applied. At the same time, however, the bonding with the sheet metal strips 9 is also improved. In addition, the expanded metal strips 6 hold the softened or melted glass very securely in the event of a fire. As already mentioned, the adhesives 13 are sufficiently heat-resistant. If a silicone adhesive is used in the edge area of the compensation adapter 5, this provides a secure seal against moisture and thus also weather protection. - The adhesives 13 are conventional fire protection adhesives, for example based on water glass or also based on silicone. The addition of metal powder is possible to increase the thermal conductivity. - It goes without saying that the components forming the compensating adapter 5 can be connected to one another before they are combined with the glass pane 1.
