Abstract
Description
Die Erfindung betrifft die Verwendung eines Sprengelementes mit einer pyrotechnischen Sprengkapsel als Brandlastsicherung an einer Fassadenverkleidung aus Einscheibensicherheitsglasscheiben. - Einscheibensicherheitsglasscheiben bezeichnet vorgespannte Glasscheiben, die im Falle von Glasbruch durch Beaufschlagung mit hoher mechanischer Energie, insbesondere bei Schlag oder Stoß in singulären Bereichen der Einscheibensicherheitsglasscheiben, in eine Vielzahl von kleinen Glaskrümeln zerfallen.The invention relates to the use of a detonating element with a pyrotechnic detonator as fire load protection on a facade cladding made of single-pane safety glass panes. - Single-pane safety glass panes refer to toughened glass panes which break down into a large number of small glass crumbs in the event of glass breakage due to exposure to high mechanical energy, in particular in the event of impact or shock in singular areas of the single-pane safety glass panes.
Fassadenverkleidungen aus Einscheibensicherheitsglasscheiben sind vielfach und in verschiedenen Ausführungsformen bekannt. Ihre Befestigung erfolgt häufig mit Hilfe von metallischen Beschlägen, die in einer Bohrung oder Ausnehmung mit den Einscheibensicherheitsglasscheiben verbunden und andererseits an dem zugeordneten Bauwerk befestigt sind.Facade claddings made of single-pane safety glass panes are widely known and in various embodiments. They are often fastened with the aid of metallic fittings, which are connected to the single-pane safety glass panes in a bore or recess and, on the other hand, are fastened to the associated structure.
In neuerer Zeit verlangt die Praxis Fassadenverkleidungen aus Einscheibensicherheitsglasscheiben, die mechanische, formschlüssige Befestigungen in Form von metallischen Beschlägen, die in Bohrungen oder Ausnehmungen der Einscheibensicherheitsglasscheiben einfassen, nicht mehr aufweisen. Hier erfolgt die Befestigung der Einscheibensicherheitsglasscheiben, z. B. mit Hilfe von Klebern. Folglich kann nicht verhindert werden, daß Einscheibensicherheitsglasscheiben aus der Fassadenverkleidung abstürzen, wenn bei Brandlast der Kleber versagt, zum Beispiel schmilzt.In recent times, practice has required facade cladding made of single-pane safety glass panes that no longer have mechanical, form-fitting fastenings in the form of metallic fittings that fit into the bores or recesses of the single-pane safety glass panes. The single-pane safety glass panes are attached here, e.g. B. with the help of adhesives. Consequently, toughened safety glass panes cannot be prevented Fall out of the facade cladding if the adhesive fails under fire, for example melts.
Brandlast bezeichnet die Temperatur, die in einem Brandfall auf die Fassadenverkleidung einwirkt.Fire load is the temperature that acts on the facade cladding in the event of a fire.
Der Erfindung liegt das technische Problem zugrunde, sicherzustellen, daß bei Fassadenverkleidungen von Bauwerken, die aus Einscheibensicherheitsglasscheiben aufgebaut sind, die Einscheibensicherheitsglasscheiben sich bei Brandlast nicht mehr lösen und als ganze Scheiben abstürzen. Außerdem soll die Feuerwehr früher den Bereich größter Hitze (Brandherd) in der Fassade erkennen.The invention is based on the technical problem of ensuring that, in the case of facade cladding of buildings which are constructed from single-pane safety glass panes, the single-pane safety glass panes no longer come loose under fire load and fall as whole panes. In addition, the fire brigade should earlier recognize the area of greatest heat (source of fire) in the facade.
Zur Lösung dieses technischen Problems ist Gegenstand der Erfindung die Verwendung eines Sprengelementes mit einer pyrotechnischen Sprengkapsel
als Brandlastsicherung an Fassadenverkleidungen aus Einscheibensicherheitsglasscheiben,
mit der Maßgabe, daß die pyrotechnische Sprengkapsel auf der Einscheibensicherheitsglasscheibe angeordnet ist, und mit der weiteren Maßgabe, daß die Sprengkapsel zur Selbstzündung bei einer vorgegebenen Brandlast eingerichtet ist. - Ein Sprengelement besteht aus einer an sich bekannten, pyrotechnischen Sprengkapsel und einem Gehäuse oder einer Aufnahme, in der die Sprengkapsel untergebracht ist. Die moderne Pyrotechnik erlaubt es problemlos, die Selbstzündungstemperatur einer Sprengkapsel durch Auswahl oder Einrichtung des Sprengstoffes so einzurichten, daß die Selbstzündung schon bei verhältnismäßig niedrigen Temperaturen, zum Beispiel bei etwa 230° C erfolgt. Folglich kann die Selbstzündung auch so eingerichtet werden, daß die Sprengkapsel bei einer vorgegebenen Brandlast zündet. Die Zündung bewirkt eine Explosion mit der Wirkung, daß die Einscheibensicherheitsglasscheibe in ihre typischen kleinen Glaskrümel zerfällt, die weniger gefährlich sind, wenn sie im Brandfall herabfallen. Ohne weiteres können für die Selbstzündung Temperaturen von zum Beispiel 200° C bis 250° C eingestellt werden. Grundsätzlich ist es bekannt (DE 20 28 550 B2), eine Einscheibensicherheitsglasscheibe durch einen in eine Bohrung der Einscheibensicherheitsglasscheibe eingesetzten Sprengsatz im Gefahrenfall zu zerstören, wobei sich die Einscheibensicherheitsglasscheibe in ihre weniger gefährlichen Glaskrümel auflöst. Auch ist es bekannt, dabei das Sprengelement auf die Oberfläche der Glasscheibe aufzusetzen. Die bekannten Maßnahmen sollen bei Kraftfahrzeugen eingesetzt werden und im Crash-Fall die Windschutzscheibe zerstören. Dazu erfolgt eine elektrische Zündung. Das technische Problem, welches bei Fassadenverkleidungen aus Einscheibensicherheitsglas im Brandfall auftritt, wird nicht angesprochen.To solve this technical problem, the subject of the invention is the use of a detonating element with a pyrotechnic detonator
as fire load protection on facade cladding made of toughened safety glass panes,
with the proviso that the pyrotechnic detonator is arranged on the single-pane safety glass pane and with the further proviso that the detonator is set up for self-ignition at a predetermined fire load. - An explosive element consists of a pyrotechnic detonator known per se and a housing or a receptacle in which the detonator is housed. Modern pyrotechnics make it easy to set the auto-ignition temperature to set up an explosive device by selecting or setting up the explosive so that the self-ignition takes place at relatively low temperatures, for example at about 230 ° C. Consequently, the autoignition can also be set up so that the detonator ignites at a predetermined fire load. The ignition causes an explosion with the effect that the toughened safety glass pane disintegrates into its typical small glass crumbs, which are less dangerous if they fall in the event of a fire. Temperatures of 200 ° C to 250 ° C, for example, can easily be set for self-ignition. Basically, it is known (DE 20 28 550 B2) to destroy a toughened safety glass pane by an explosive device inserted into a bore in the toughened safety glass pane in the event of danger, the toughened safety glass pane dissolving into its less dangerous glass crumbs. It is also known to place the blasting element on the surface of the glass pane. The known measures are to be used in motor vehicles and destroy the windshield in the event of a crash. This is done by an electric ignition. The technical problem that arises with facade cladding made of toughened safety glass in the event of a fire is not addressed.

So weist das Sprengelement zweckmäßigerweise eine metallische Berstspitze auf, die an der Einscheibensicherheitsglasscheibe anliegt. Zweckmäßigerweise ist die Einscheibensicherheitsglasscheibe bohrungsfrei, auch sackbohrungsfrei, ausgeführt und liegt die Berstspitze an der glatten Oberfläche der Einscheibensicherheitsglasscheibe an. Die mechanischen Beschläge, die die Einscheibensicherheitsglasscheibe festhalten, können auch im Bereich von Ecken der Einscheibensicherheitsglasscheibe und diese umfassend angeordnet werden.In particular, there are several options for the further development of the measures according to the invention. For example, the blasting element expediently has a metallic bursting tip which lies against the single-pane safety glass pane. The single-pane safety glass pane is expedient The drill tip is free of holes, also without blind holes, and lies against the smooth surface of the single-pane safety glass pane. The mechanical fittings which hold the toughened safety glass pane can also be arranged in the region of corners of the toughened safety glass pane and can be arranged comprehensively.
