Brandschutzverqlasunq Brandschutzverqlasunq
Die Erfindung betrifft eine Brandschutzverglasung zur Vermeidung des Durchtritts von Feuer und Rauch im Brandfall aus einem Raum in einen anderen, mit mindestens zwei horizontal und/oder vertikal fluchtend unter Belassung einer Fuge zueinander angeordneten Brandschutzscheiben, die jeweils aus zwei auf Abstand gehaltenen, parallelen Glasscheiben aufgebaut sind, deren geschlossener Innenraum mit einem insbesondere gelartigen Brandschutzmittel gefüllt ist, wobei in der zwischen den Stoßflächen der Brandschutzscheiben ausgebildeten Fuge ein feuerhemmendes Isoliermittel angeordnet ist.The invention relates to a fire-resistant glazing to prevent the passage of fire and smoke in case of fire from one room to another, with at least two horizontally and / or vertically aligned leaving a joint to each other arranged fire protection panels, each constructed from two spaced, parallel glass panes are, whose closed interior is filled with a particular gel-like fire retardant, wherein in the formed between the abutment surfaces of the fire doors joint a fire-retardant insulating agent is arranged.
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. Hierzu werden Brandschutzscheiben verwendet, die mehrlagig aus Glasscheiben mit einer jeweils dazwischen angeordneten Brandschutzschicht (Intumeszenzmaterial) aufgebaut sind. Im Brandfall wird diese Brandschutzschicht aktiviert. Sie absorbiert die Wärmestrahlung und bildet eine hochwirksame Dämmschicht. Das aufschäumende Brandschutzmaterial tritt dabei aus den Stoßflächen der Brandschutzscheibe aus und verschließt die jeweils zur angrenzenden Brandschutzscheibe belassene Fuge, so dass Flammen, Rauch und Wärme nicht mehr durchtreten können. Nachteiligerweise funktioniert bei aus solchen Brandschutzscheiben aufgebauten Brandschutzverglasungen der Rauch- und Feuerverschluß nur aufgrund des Austritts des intumeszierenden Brandschutzmaterials in die Fugenbereiche.Fire-resistant glazings are translucent components designed to prevent not only the spread of fire and smoke, but also the inadmissible transfer of heat, according to their fire resistance duration. For this purpose, fire protection panes are used, which are constructed in multiple layers of glass panes with a respective interposed fire protection layer (intumescent). In case of fire, this fire protection layer is activated. It absorbs heat radiation and forms a highly effective insulating layer. The foaming fire protection material exits from the abutting surfaces of the fire protection pane and closes the gap left in each case to the adjacent fire protection pane so that flames, smoke and heat can no longer pass through. Disadvantageously works with built-up such fire protection glass fire-resistant glazing of the smoke and fire lock only due to the exit of the intumescent fire protection material in the joint areas.
Es ist ferner aus der EP 1 194 673 B1 eine prinzipiell anders aufgebaute Brandschutzverglasung bekannt, bei der Brandschutz-Glasplatteneinheiten verwendet werden, die aus mehreren Floatglasscheiben mit dazwischen angeordneter Brandschutzschicht aus einer gelartigen, wasserhaltigen Alkalimetallsilikatmasse aufgebaut sind. Diese Gelschichten schäumen im Brandfall nicht auf. Vielmehr sind derartige Brandschutzschichten glaswandseitig mit einer Nut versehen, in die ein Sperrmaterial zur feuchtigkeits- und luftdichten Abdichtung des verwendeten Brandschutzmittels eingesetzt ist. Nachteiligerweise werden hierbei eine Vielzahl von Glasscheiben und eine Vielzahl dazwischen angeordneter Brandschutzmittelschichten mit aufwändiger wandseitiger Absperrung zur Stoßfuge hin verwendet.It is also known from EP 1 194 673 B1 discloses a fundamentally differently structured fire-resistant glazing, are used in the fire-resistant glass plate units consisting of several float glass panes with in between arranged fire protection layer of a gel-like, aqueous alkali metal silicate mass are constructed. These gel layers do not foam in the event of fire. Rather, such fire protection layers are glass wall side provided with a groove in which a barrier material is used for moisture and airtight sealing of the fire retardant used. Disadvantageously, in this case a plurality of glass panes and a plurality of interposed fire protection layers are used with elaborate wall-side barrier to butt.
Im Rahmen einer Weiterentwicklung dieser bekannten Brandschutzverglasung zur Behebung der genannten Nachteile ist gemäß 02 070 234 eine alternative Brandschutzverglasung vorgeschlagen worden, die weniger Glasscheiben benötigt, einfacher aufgebaut ist und in der Stoßfuge eine höhere Sicherheit gegen den Durchtritt von Feuer und Rauch bietet. Die bekannte Brandschutzverglasung weist mindestens zwei transparenteAs part of a further development of this known fire-resistant glazing to remedy the above disadvantages, an alternative fire-resistant glazing has been proposed according to 02 070 234, which requires less glass, has a simpler structure and provides higher security against the passage of fire and smoke in the butt joint. The known fire-resistant glazing has at least two transparent
Brandschutzglasplatteneinheiten auf, die an den Seitenkanten mittelbar aneinanderstoßen und deren übrige Seitenkanten an einem Bauteil gehalten sind, wobei jede Brandschutz-Glasplatteneinheit aus auf Abstand gehaltenen, parallelen Glasscheiben aufgebaut ist, zwischen denen ein Brandschutzmittel angeordnet ist. Dabei ist zwischen den über die Stoßfuge einander gegenüberliegenden Seitenkanten der Brandschutz-Glasplatteneinheiten eine feuerhemmende Isoliermittelanordnung eingebracht. Jede Brandschutz-Glasplatteneinheit ist aus zwei nach Art einer Isolierglasscheibenanordnung mittels Abstandshalter und einem PU-Randverbund auf Abstand und aneinandergehaltenen ESG-Scheiben aufgebaut, deren Innenraum mit einem Gel als Brandschutzmittel ausgefüllt ist, wobei im Bereich der Fuge zwischen den mindestens zwei Brandschutz- Glasplatteneinheiten als Isoliermittelanordnung feuerhemmendes keramisches Isolierband eingelegt ist. Da bei dieser bekannten Brandschutzverglasung nur die senkrechten inneren Seitenkanten der mindestens zwei Glasplatteneinheiten mittelbar aneinanderstoßen und alle übrigen Seiten durch einen umlaufenden Rahmen gehalten sind, lässt sich eine breitere oder höhere Verglasung, die nach der Seite und/oder der Höhe weitere mittelbar aneinanderstoßende Glasplatteneinheiten aufweist, mit der bekannten Haltekonstruktion (Rahmen) nicht verwirklichen. Durch die Verwendung des Rahmens ist die konstruktive Freiheit für die Bereitstellung großflächiger Brandschutzverglasungen eingeschränkt. Der Erfindung liegt in Anbetracht dieses Standes der Technik die A u f g a b e zugrunde, eine Brandschutzverglasung unter Verwendung der beschriebenen Brandschutz-Glasplatteneinheiten zu entwickeln, die einfach aufgebaut ist, eine weiter erhöhte Sicherheit gegen den Durchtritt von Feuer und Rauch gewährleistet und eine derart verstärkte Stabilität auch im Brandfall bietet, dass größere Breiten, wie auch insbesondere größere Höhen für großflächige Brandschutzverglasungen erzielt werden können und hierdurch eine erweiterte konstruktive Freiheit erzielt wird.Fire protection glass plate units which abut indirectly on the side edges and the remaining side edges are held on a component, each fire protection glass plate unit is constructed of spaced, parallel glass panes, between which a fire retardant is arranged. In this case, a fire-retardant Isoliermittelanordnung is introduced between the over the butt joint opposite side edges of the fire protection glass panel units. Each fireproof glass panel unit is constructed of two in the manner of an insulating glass pane assembly by means of spacers and a PU edge seal at a distance and held together ESG panes whose interior is filled with a gel as a fire retardant, wherein in the joint between the at least two fire protection glass panel as Isoliermittelanordnung fire-retardant ceramic insulating tape is inserted. Since in this known fire-resistant glazing only the vertical inner side edges of the at least two glass plate units abut indirectly and all other sides are held by a peripheral frame, can be a wider or higher glazing, which has on the side and / or height further indirectly abutting glass plate units, with the known support structure (frame) not realize. The use of the frame limits the design freedom for the provision of large-area fire-resistant glazing. The invention is in the light of this prior art, the object of the invention to develop a fire-resistant glazing using the fire-resistant glass plate units described, which is simple in construction, a further increased security against the passage of fire and smoke and ensures such increased stability in the Fire offers that larger widths, as well as in particular larger heights for large-scale fire-resistant glazing can be achieved and thus an extended structural freedom is achieved.
Die Aufgabe ist erfindungsgemäß dadurch g e l ö s t , dass die Brandschutzscheiben im Randbereich zu beiden Seiten durch jeweils ein Profil gehalten sind, dass die einander gegenüberliegenden Profile die zwischen den Brandschutzscheiben bzw. der Brandschutzscheibe und der benachbarten raumbegrenzenden Struktur gebildete Fuge überdecken und dass die einander gegenüberliegenden Profile thermisch getrennt ausschließlich über die als Isolierschicht dienenden Brandschutzscheiben miteinander verbunden sind. Durch die all- und beidseitige Halterung der Brandschutzscheiben im Randbereich unter Überdeckung der jeweiligen Fuge wird eine außerordentliche Verbesserung der Stabilität der Brandschutzverglasung erreicht und damit der Aufbau großflächiger Verglasungen ermöglicht. Es ist ohne weiteres möglich, in Abhängigkeit von der Stärke der verwendeten Profile Verglasungen mit 5 m, 6 m und größer 7 m Höhe aufzubauen, obwohl keine rahmenartige Einfassung der einzelnen Brandschutzscheiben gegeben ist, diese vielmehr einfach übereinander angeordnet werden. Dabei können so viele Brandschutzscheiben aufeinandergestellt werden, wie deren Eigen-Tragfähigkeit es zulässt.The object is achieved according to the invention by the fact that the fire protection panes are held in the edge region on both sides by a respective profile, that the opposing profiles cover the gap formed between the fire panes or the fire protection pane and the adjacent raumbegrenzenden structure and that the opposing Profiles are thermally separated exclusively connected to each other via the serving as an insulating fire barriers. Due to the all- and two-sided mounting of the fire protection windows in the edge area under cover of the respective joint an extraordinary improvement in the stability of the fire-resistant glazing is achieved and thus allows the construction of large-scale glazing. It is readily possible, depending on the strength of the profiles used to build glazing with 5 m, 6 m and greater than 7 m in height, although no frame-like enclosure of the individual fire protection is given, they are simply superimposed. As many fire protection panels can be stacked on top of each other as their own load-bearing capacity permits.
Vorteilhafterweise sind die einander gegenüberliegenden Profile jeweils mit den beiden Brandschutzscheiben bzw. der Brandschutzscheibe und der benachbarten raumbegrenzenden Struktur mittels einer Silikondichtmasse im Sinne einer Stabilitätserhöhenden Verklebung einerseits und zum Schutz der Fuge andererseits verbunden. Die Breite der Fuge beträgt zweckmäßigerweise größer 6 mm, vorzugsweise größer 10 mm.Advantageously, the opposing profiles are each connected to the two fire protection windows or the fire protection pane and the adjacent space-limiting structure by means of a silicone sealant in the sense of a stability-enhancing bonding on the one hand and to protect the joint on the other. The width of the joint is expediently greater than 6 mm, preferably greater than 10 mm.
Mit der Erfindung können eine Vielzahl von Brandschutzscheiben horizontal und/oder vertikal fluchtend zueinander angeordnet und jeweils im Randbereich die zugehörige Fuge überdeckend durch zu beiden Seiten angeordnete Profile gehalten werden. Dabei ist es besonders vorteilhaft, die Profile als Stahlhohlprofile auszubilden.With the invention, a plurality of fire protection windows horizontally and / or vertically aligned with each other and each in the edge region of the associated joint overlapping by arranged on both sides of profiles being held. It is particularly advantageous to design the profiles as hollow steel profiles.
Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Brandschutzscheiben aus Einscheibensicherheitsglas mit U-förmigen Abstand haltern und einem PU-Randverbund aufgebaut und ist im Fugenbereich ein feuerhemmendes keramisches Isolierband als Isoliermittel eingelegt. Alternativ kann das Isoliermittel auch aus Mineralwolle oder Intumeszenzmaterial in Form von Streifen bestehen. Es ist vorteilhaft, den U-förmigen Abstandhalter als gelresistentem, feuerständigem Kunststoff herzustellen.According to a preferred embodiment of the invention, the fire panes are made of single-pane safety glass with U-shaped spacers and a PU edge seal and is inserted in the joints area a fire-retardant ceramic insulating tape as insulating. Alternatively, the insulating agent may also consist of mineral wool or intumescent material in the form of strips. It is advantageous to produce the U-shaped spacer as gelresistentem fire-resistant plastic.

In der Zeichnung zeigt:Further details, features and advantages of the subject matter of the invention will become apparent from the following description of the accompanying drawings, in which a preferred embodiment of a large-scale fire-resistant glazing is shown.

Die in Fig. 1 der Zeichnung dargestellte Brandschutzverglasung in Form einer Feuerschutztrennwand ist geeignet und vorgesehen, den Durchtritt von Feuer und Rauch im Brandfall aus einem Raum in einen anderen zu verhindern. Es handelt sich um eine großflächige Verglasung, die aus insgesamt acht Brandschutzscheiben 1 , 2, 3, 4, 5, 6, 7 und 8 aufgebaut ist, welche in einer senkrechten Ebene fluchtend nebeneinander und übereinander angeordnet sind. Dabei ist die Anordnung der Brandschutzscheiben zueinander grundsätzlich derart, dass zwischen benachbarten Rändern eine Fuge von größer 6 mm belassen ist, wie weiter unter näher unter Bezug auf die Schnittzeichnungen erläutert ist. Die Brandschutzverglasung in ihrer Gesamtheit ist beispielsweise in einer Wandausnehmung eines Gebäudes gehalten oder unmittelbar an seitlichen Wänden sowie der Decke und dem Boden eines Gebäuderaumes befestigt. Die Brandschutzscheiben 1 bis 8 können unterschiedliche Abmessungen aufweisen und entsprechend den architektonischen Erfordernissen, wie Fig. 1 verdeutlicht, miteinander kombiniert werden. So sind im Ausführungsbeispiel vergleichsweise lange Brandschutzscheiben 1 bzw. 7 in vertikaler Richtung oder horizontaler Richtung sich erstreckend angeordnet und es sind quadratische Brandschutzscheiben 6 bzw. 8 in vertikaler Richtung übereinander angeordnet, und dazu - um Höhe zu gewinnen - mit einer rechteckigen Brandschutzscheibe 4 in senkrechter Richtung kombiniert, und sind schließlich weitere Kombinationen von Rechteck-Brandschutzscheiben 2, 3 und 5 in Fig. 1 schematisch dargestellt, um die Variabilität der möglichen Anordnungen und die dadurch gewährte konstruktive Freiheit zu verdeutlichen.The fire protection glazing shown in Fig. 1 of the drawing in the form of a fire wall is suitable and intended to prevent the passage of fire and smoke in case of fire from one room to another. It is a large-scale glazing, which is composed of a total of eight fire protection windows 1, 2, 3, 4, 5, 6, 7 and 8, which are arranged in a vertical plane in alignment next to each other and one above the other. In this case, the arrangement of the fire protection glass to each other is basically such that between adjacent edges a gap of greater than 6 mm is left, as further explained below with reference to the sectional drawings. The fire-resistant glazing in its entirety is kept, for example, in a wall recess of a building or attached directly to side walls and the ceiling and the floor of a building room. The fire protection panels 1 to 8 may have different dimensions and according to the architectural requirements, as Fig. 1 illustrates, are combined. Thus, in the exemplary embodiment comparatively long fire protection plates 1 and 7 are arranged extending in the vertical direction or horizontal direction and there are square fire protection panels 6 and 8 arranged vertically one above the other, and - to gain height - with a rectangular fire protection screen 4 in vertical Combined direction, and finally other combinations of rectangular fire protection panels 2, 3 and 5 are shown schematically in Fig. 1 in order to illustrate the variability of the possible arrangements and the constructive freedom granted thereby.
Prinzipiell sind die Brandschutzscheiben 1 bis 8 identisch aufgebaut. Sie unterscheiden sich nur in Form und Abmessungen. Beispielhaft wird daher der Aufbau der Brandschutzscheibe 1 unter .Bezugnahme auf Fig. 2 der Zeichnung nachfolgend beschrieben:In principle, the fire protection windows 1 to 8 are constructed identically. They differ only in shape and dimensions. By way of example, therefore, the construction of the fire protection pane 1 will be described below with reference to FIG. 2 of the drawing:
Die Brandschutzscheibe 1 besteht aus zwei parallel mit Abstand zueinander angeordneten Scheiben 9 und 10 aus Einscheibensicherheitsglas. Zwischen den Scheiben 9 und 10 ist randumlaufend ein U-förmiger Abstandhalter 11 aus brandschutzmittelbeständigem und feuerresistentem Kunststoff angeordnet. Der Abstandhalter 11 ist etwas nach innen gegenüber den Rändern der beiden Scheiben 9 und 10 zurückversetzt. Die dadurch gebildete umlaufende Nut ist durch einen PU-Randverbund 12 ausgefüllt, so dass die beiden ESG-Scheiben 9 und 10 aneinander unter Bildung eines geschlossenen Innenraums nach Art einer Isolierverglasung fixiert sind. Zur Erzielung der gewünschten Brandschutzeigenschaften ist dieser Innenraum 13 mit einem gelartigen Brandschutzmittel gefüllt, das als solches an sich bekannt ist und daher nicht näher beschrieben wird. Im Gegensatz zu anderen Brandschutzgläsern schäumt das gelartige Brandschutzmittel im Brandfall nicht auf und kann auch den beschriebenen Innenraum 13 der Brandschutzscheibe nicht verlassen.The fire protection pane 1 consists of two parallel spaced apart disks 9 and 10 of single-pane safety glass. Between the discs 9 and 10, a U-shaped spacer 11 made of fire-resistant and fire-resistant plastic is circumferentially arranged. The spacer 11 is set back slightly inwards in relation to the edges of the two disks 9 and 10. The circumferential groove formed thereby is filled by a PU edge seal 12, so that the two tempered glass panes 9 and 10 are fixed to each other to form a closed interior in the manner of insulating glazing. To achieve the desired fire protection properties of this interior 13 is filled with a gel-like fire retardant, which is known per se and therefore not described in detail. In contrast to other fire-resistant glass foams the gel-like fire-retardant in case of fire and can not leave the described interior 13 of the fire protection pane.

Allerdings wird in der waagerechten Stoßfuge 14 die Anordnung der Brandschutzscheiben 4 und 6 aufeinander über nicht dargestellte, an sich bekannte Klötzchen vorgenommen, wobei in der Stoßfuge 14 entsprechend Fig. 2 keramische Isolierbänder 15 und 16 angeordnet sind.Fig. 3 of the drawing shows in section the holder of the superposed fire protection panels 6 and 4 by means of hollow steel profiles, being dispensed with a more detailed description due to the identity of the structure to the steel profile bracket of FIG. However, in the horizontal butt joint 14, the arrangement of the fire protection panels 4 and 6 on each other via not shown, per se known blocks made, wherein in the butt joint 14 as shown in FIG. 2 ceramic insulating tapes 15 and 16 are arranged.
Fig. 4 der Zeichnung zeigt die wandseitige Stahlprofilhalterung der Brandschutzscheibe 4, die im Prinzip identisch zur oben beschriebenen Halterung aufgebaut ist, wobei allein die Wand als raumbegrenzende Struktur anstelle der zweiten (benachbarten) Brandschutzscheibe tritt und der in der Stoßfuge 14 zur Wand hin verbleibende Hohlraum mit nicht brennbarer Mineralwolle 20 verfüllt ist. Sämtliche Stahlprofile der Stahlprofilhalterung sind an den Stoßstellen miteinander verschweißt oder anderweitig aneinander gehalten bzw. wand-, boden- und deckenseitig über Schraubverbindungen entsprechend Fig. 4 befestigt.Fig. 4 of the drawing shows the wall-side steel profile bracket of the fire protection panel 4, which is constructed in principle identical to the above-described holder, with only the wall as raumbegrenzende structure instead of the second (adjacent) fire protection glass occurs and in the butt joint 14 to the wall remaining cavity filled with non-combustible mineral wool 20. All steel profiles of the steel profile bracket are welded together at the joints or otherwise held together or wall, floor and ceiling side secured by screw according to Fig. 4.
Das beschriebene Ausführungsbeispiel ermöglicht es, eine Feuerschutztrennwand F einer Höhe H von mehr als 3 m, im Beispiel von 4 m, ohne weitere Stabilitätserhöhende Maßnahmen zu erstellen, wobei durch die vollständige thermische Trennung der einander gegenüberliegenden Stahlhohlprofile und der Wirkung der aneinandergrenzenden Brandschutzscheiben als Isolierschicht im Brandfall der feuer- und rauchdichte Abschluss sichergestellt ist. The described embodiment makes it possible to create a fire protection partition F of a height H of more than 3 m, in the example of 4 m, without further stability-increasing measures, with the complete thermal separation of the opposing steel hollow sections and the effect of contiguous fire panels as an insulating layer in Fire case of fire and smoke-tight completion is ensured.
