Description

Die Erfindung betrifft eine brandhemmende Verglasung aus Glasscheiben aus Einscheibensicherheitsglas.The invention relates to fire-retardant glazing made of glass panes Single-pane safety glass.

Bei brandhemmenden Verglasungen war es bisher üblich, die einzelnen Glasscheiben aus Einscheibensicherheitsglas mittels die Glasscheiben einfassenden Metallrahmen zu fixieren. Diese Lösung ist zwar sicher, verlangt jedoch einen hohen konstruktiven Aufwand und ist insofern problematisch, als im Brandfall das Glas und das Metall mit unterschiedlicher Ausdehnung auf die Erwärmung reagieren.In the case of fire-retardant glazing, it was previously common for the individual glass panes made of toughened safety glass by means of metal frames surrounding the glass panes to fix. Although this solution is safe, it requires a high level of design Effort and is problematic insofar as the glass and metal are included in the event of a fire different expansion react to the warming.

Im Gegensatz dazu sieht die Erfindung vor, daß die Glasscheiben mittels in Ausnehmungen in den Glasscheiben eingreifenden Punkthaltern verankert sind, wobei die Einstandstiefe der Glasscheiben in die Punkthalter geringer ist als die 1,5fache Dicke der Glasscheiben.In contrast, the invention provides that the glass panes by means of Recesses are anchored in the point holders engaging the glass panes, wherein the penetration depth of the glass panes in the point holder is less than 1.5 times Thickness of the glass panes.

Umfangreiche Versuche der Anmelderin haben ergeben, daß wider Erwarten nur geringe Einstandstiefen der Glasscheiben in die Punkthalter eine sichere Fixierung im Brandfall gewährleisten. Obwohl die geringe Einstandstiefe zu einer hohen Flächenpressung der Glasscheiben in den Punkthaltern führt, darf die Einspannfläche nicht vergrößert werden, da sonst die unterschiedliche Erwärmung des direkt dem Feuer ausgesetzten Glases und des durch die Punkthalter geschützten Glases zu Spannungen führt, die die Glasscheibe zerstören.Extensive tests by the applicant have shown that, contrary to expectations, only small penetration depths of the glass panes in the point holder secure fixation in the Ensure a fire. Although the low cost of acquisition to a high Surface pressure of the glass panes in the point holders, the clamping surface may not be enlarged, otherwise the different heating of the directly Exposed glass and the glass protected by the point holder Leads to tensions that destroy the glass pane.

Einer geringen Einstandstiefe widerspricht auch die Tatsache, daß sich das Glas im Brandfall so hoch erhitzt, daß es erweicht, wodurch die Klemmwirkung im Punkthalter teilweise verlorengeht. Die Glasscheibe hängt dann nur mehr an dem die Ausnehmungen in den Glasscheiben durchsetzenden Bereich der Punkthalter, wobei die Gefahr besteht, daß sich die Ausnehmungen aufweiten und die Glasscheibe von den Punkthaltern freikommt. Auch hier haben umfangreiche Versuche gezeigt, daß eine Einspanntiefe unterhalb des 1,5fachen der Dicke des Glases ausreichend ist.A low depth of purchase also contradicts the fact that the glass in the In the event of a fire, it is heated to such an extent that it softens, causing the clamping effect in the point holder partially lost. The glass pane then only hangs on the Recesses in the area of the point holder penetrating the glass panes, wherein there is a risk that the recesses widen and the glass pane from the point holders are released. Extensive tests have shown that a clamping depth below 1.5 times the thickness of the glass is sufficient.

Um im Brandfall einen direkten Kontakt der Glasscheibe mit den Punkthaltern zu vermeiden, ist vorzugsweise vorgesehen, daß die Punkthalter in dem die Ausnehmungen durchsetzenden Bereich mit einer feuerfesten Auflage versehen sind. To ensure direct contact between the glass pane and the point holders in the event of a fire avoid, it is preferably provided that the point holder in which the Recess through area are provided with a refractory pad.

Besonders einfach ist es, wenn die feuerfeste Auflage hülsenförmig ausgebildet ist. Als Material für die Auflage haben sich verschiedene Steinmehl-Verbunde bewährt.It is particularly simple if the refractory support is sleeve-shaped. As Various stone meal composites have proven their worth for the overlay.

Weitere Merkmale und Einzelheiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Figurenbeschreibung. Dabei zeigt:

einen Schnitt durch zwei aneinandergrenzende Glasscheiben im Bereich der Punkthalter.
Further features and details of the present invention result from the following description of the figures. It shows:
Fig. 1
a pane of toughened safety glass with recesses for point holders and
Fig. 2
a section through two adjacent glass panes in the area of the point holder.

Die erfindungsgemäße brandhemmende Verglasung besteht aus einer Vielzahl von Glasscheiben 3 aus Einscheibensicherheitsglas. Diese Glasscheiben 3 sind mittels Punkthaltern 2 an einem Traggerüst 1 befestigt.The fire-retardant glazing according to the invention consists of a variety of Glass panes 3 made of toughened safety glass. These glass panes 3 are Point holders 2 attached to a support frame 1.

Dazu weisen die Glasscheiben 3 Ausnehmungen 5 in Form kreisrunder Bohrungen auf. Die Ausnehmungen 5 sind vorzugsweise in den Eckbereichen der Glasscheiben 3 angeordnet. Es können jedoch bei Bedarf auch zusätzliche Ausnehmungen 5 entlang der Seitenkanten der Glasscheiben 3 vorgesehen sein.For this purpose, the glass panes have 3 recesses 5 in the form of circular bores on. The recesses 5 are preferably in the corner regions of the glass panes 3 arranged. However, additional recesses 5 can also be along if necessary the side edges of the glass panes 3 may be provided.

Die Punkthalter 2, die die Ausnehmungen 5 durchsetzen, sind im wesentlichen zweiteilig aufgebaut. Sie bestehen aus einem inneren Teller 6 und einem äußeren Teller 8, die mittels Schrauben 10 miteinander verschraubt sind. Durch die Verschraubung der Teller 6 und 8 wird die Einspannung der Glasscheiben 3 erzielt. Zur Vermeidung eines direkten Kontaktes der Teller 6 und 8 aus Metall mit dem Glas sind Dichtringe 9 aus feuerfestem Material vorgesehen.The point holders 2 which pass through the recesses 5 are essentially constructed in two parts. They consist of an inner plate 6 and an outer one Plates 8 which are screwed together by means of screws 10. Through the The plates 6 and 8 are screwed together to secure the glass panes 3. For Avoid direct contact of plates 6 and 8 made of metal with the glass Sealing rings 9 made of refractory material are provided.

Wesentlich ist die Einstandstiefe e der Glasscheiben 3 in die Punkthalter 2. Die Einstandstiefe e entspricht in etwa der Dicke d der Glasscheiben 3.What is essential is the penetration depth e of the glass panes 3 into the point holders 2 Entry depth e corresponds approximately to the thickness d of the glass panes 3.

Für den Fall, daß bei starker Erwärmung der Glasscheiben das Glas erweicht und die Klemmwirkung in den Punkthaltern 2 verloren geht, ist in dem die Ausnehmungen 5 in den Glasscheiben 3 durchsetzenden Bereich der Punkthalter 2 eine feuerfeste Auflage 7 vorgesehen. Diese Auflage 7 ist hülsenförmig und besteht aus einem Steinmehl-Verbund. Die Auflage 7 verhindert einerseits einen direkten Kontakt von Glas und Metall. Andererseits ist die Auflage 7 so stabil, daß sie durch das Gewicht der Glasscheibe 3 nicht zusammengedrückt wird, was bewirken würde, daß die Glasscheibe an der gegenüberliegenden Seite aus dem Punkthalter 2 herausrutschen könnte.In the event that when the glass panes are heated excessively, the glass softens and the Clamping effect in the point holders 2 is lost, in which the recesses 5 in the area of the point holder 2 passing through the glass panes 3 has a refractory support 7 provided. This edition 7 is sleeve-shaped and consists of a stone powder composite. The pad 7 prevents direct contact between glass and Metal. On the other hand, the pad 7 is so stable that the weight of the Glass 3 is not compressed, which would cause the Slide the glass pane out of the point holder 2 on the opposite side could.

Um die brandhemmende Wirkung der Verglasung auch im Stoßbereich der Glasscheiben 3 sicherzustellen, ist dieser Stoßbereich mit Brandschutzsilikon 4 gefüllt.To the fire-retardant effect of the glazing even in the joint area of the To ensure glass panes 3, this joint area is filled with fire protection silicone 4.

Um zu vermeiden, daß über die Punkthalter 2 Spannungen in die Glasscheiben 3 eingeleitet werden, können die Punkthalter 2, wie an sich bekannt, mit Kugelgelenken 11 ausgebildet sein.In order to avoid tensions in the glass panes 3 via the point holders 2 can be initiated, the point holder 2, as known per se, with ball joints 11 be formed.
