Definitions
- the invention relates to a pressure relief facade for buildings at risk from sudden pressure differences, consisting of panel-shaped wall elements which are attached to the edge facing the building facing side in such a way that they release at a certain room pressure.
- a solution has become known from CH-A 531 124 in which glass panes with the decay characteristics of thermally toughened glass are used.
- a pointed stop is mounted on the pressure side of each disc so that the distance to the disc is less than the maximum deflection of the disc area under the stop, which the disc can still suffer without breaking.
- the pressure relief facade described at the outset can be found in US Pat. No. 3,807,106.
- the holding means mentioned consist of flanges screwed to the panel-shaped wall element, which are fixed to flanges firmly connected to the building by numerous bolts penetrating the two flanges. These lie on the side facing the building with a head against the flange on the building side and, at their free end facing away from the building, which projects beyond the flange screwed to the panel-shaped wall element, has a bore through which a shear wire is inserted.
- the invention is therefore based on the object of developing a pressure relief facade which has an easy to install enlarged facade area portion for pressure relief.
- the panel-shaped wall elements preferably the parapet parts located below the windows, each have a circumferential, perpendicular to the facade level retaining leg in their edge area on their side facing the building, which at its free edge in a thickened terminal strip passes, which is pressed into an undercut clamping slot of a plastic profile fixed in the facade and is detachably held there in an elastic positive connection.

- the terminal strip seen in cross-section in the pushing-in direction, can have a steep run-up slope which merges into an oppositely running flat run-off slope, which is gripped by a clamping lip of the plastic profile, which merges into an insertion slot which widens conically towards the outside of the facade.
- this ensures that the terminal strip is easily pressed into its elastic form fit.
- this elastic shape absorbs the wind suction forces acting on the wall element, but dissolves almost suddenly when a certain internal pressure is reached. This effect can also be ensured by the fact that the clamping lip delimits a profile cavity which is arranged behind it in all directions on the pull-out direction. This ensures sufficient strength on the one hand and sufficient flexibility of the clamping lip on the other.

Abstract
Description
Die Erfindung betrifft eine Druckentlastungsfassade für durch plötzliche Druckdifferenzen gefährdete Gebäude, bestehend aus tafelförmigen Wandelementen, die über in ihren Randbereichen auf der dem Gebäude zugewandten Seite angeordnete Haltemittel derart an diesem befestigt sind, daß sie sich bei einem bestimmten Rauminnendruck lösen.The invention relates to a pressure relief facade for buildings at risk from sudden pressure differences, consisting of panel-shaped wall elements which are attached to the edge facing the building facing side in such a way that they release at a certain room pressure.
Plötzliche Druckdifferenzen können durch Verpuffungen, Explosionen oder Detonationen verursacht werden, wobei die Geschwindigkeit des Druckanstieges bei Verpuffungen am kleinsten und bei Detonationen am größten ist. Damit ein plötzlicher Druckanstieg nicht zu einer Zerstörung des gesamten Gebäudes führt, ist es erforderlich, in der Fassade mehrere "Sollbruchstellen" vorzusehen. Bisher ist es üblich, speziell dünn verglaste Fenster für diese "Sollbruchstellen" vorzusehen. Wenn der Druckanstieg im Innern des Gebäudes einen bestimmten Wert erreicht, bersten diese dünn verglasten Fenster und ermöglichen so eine schnelle Druckentlastung; alle tragenden Wandteile bleiben dabei unbeschädigt.Sudden pressure differences can be caused by deflagrations, explosions or detonations, with the rate of pressure increase being the smallest in the case of deflagrations and the greatest in the case of detonations. So that a sudden increase in pressure does not lead to the destruction of the entire building, it is necessary to provide several "predetermined breaking points" in the facade. So far, it has been customary to provide specially thin-glazed windows for these "predetermined breaking points". When the pressure increase inside the building reaches a certain value, these thinly glazed windows burst and thus enable rapid pressure relief; all load-bearing wall parts remain undamaged.
Durch die CH - A 531 124 ist eine Lösung bekanntgeworden, bei der Glasscheiben mit der Zerfallcharakteristik von thermisch vorgespanntem Glas verwendet werden. Dabei wird auf der Neiderdruckseite jeder Scheibe ein spitzer Anschlag so montiert, daß der Abstand zur Scheibe kleiner ist als die maximale Auslenkung des unter dem Anschlag befindlichen Scheibenbereichs, den die Scheibe ohne Bruch gerade noch erleiden kann.A solution has become known from CH-A 531 124 in which glass panes with the decay characteristics of thermally toughened glass are used. A pointed stop is mounted on the pressure side of each disc so that the distance to the disc is less than the maximum deflection of the disc area under the stop, which the disc can still suffer without breaking.
Voraussetzung für diese bekannten Lösungsvorschläge ist ein ausreichend großer Glasbereich bezogen auf die Gesamtfassade, um bei einem plötzlichen Druckanstieg eine ausreichend schnelle Druckentlastung gewährleisten zu können. Diese Voraussetzung ist jedoch beispielsweise dann nicht mehr gegeben, wenn die einzelnen Gebäudeteile geschlossene Sektoren bilden, die nur auf einer Seite eine Fassade erhalten.A prerequisite for these known proposed solutions is a sufficiently large glass area in relation to the entire facade in order to be able to guarantee a sufficiently rapid pressure relief in the event of a sudden pressure increase. However, this requirement is no longer met, for example, if the individual parts of the building form closed sectors that only have a facade on one side.
Die eingangs beschriebene Druckentlastungsfassade läßt sich der US - A - 3 807 106 entnehmen. Dabei bestehen die genannten Haltemittel aus mit dem tafelförmigen Wandelement verschraubten Flanschen, die an fest mit dem Gebäude verbundenen Flanschen festgelegt sind durch zahlreiche, die beiden Flansche durchdringende Bolzen. Diese liegen auf der dem Gebäude zugewandten Seite mit einem Kopf gegen den gebäudeseitigen Flansch an und weisen an ihrem dem Gebäude abgewandten freien Ende, das den an dem tafelförmigen Wandelement verschraubten Flansch überragt, eine Bohrung auf, durch die ein Abscherdraht gesteckt ist.The pressure relief facade described at the outset can be found in US Pat. No. 3,807,106. The holding means mentioned consist of flanges screwed to the panel-shaped wall element, which are fixed to flanges firmly connected to the building by numerous bolts penetrating the two flanges. These lie on the side facing the building with a head against the flange on the building side and, at their free end facing away from the building, which projects beyond the flange screwed to the panel-shaped wall element, has a bore through which a shear wire is inserted.
Da für ein großflächiges Wandelement zahlreiche Bolzen mit Scherdraht vorgesehen werden müssen, ist die Montage außerordentlich aufwendig.Since numerous bolts with shear wire must be provided for a large wall element, the assembly is extremely complex.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Druckentlastungsfassade zu entwickeln, die einen einfach zu montierenden vergrößerten Fassadenflächen-Anteil für eine Druckentlastung aufweist.The invention is therefore based on the object of developing a pressure relief facade which has an easy to install enlarged facade area portion for pressure relief.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die tafelförmigen Wandelemente, vorsugsweise die unterhalb der Fenster liegenden Brüstungsteile, in ihrem Randbereich auf ihrer dem Gebäude zugewandten Seite jeweils einen umlaufenden, senkrecht auf der Fassadenebene stehenden Halteschenkel aufweisen, der an seinem freien Rand in eine verdickte Klemmleiste übergeht, die in einen hinterschnittenen Klemmschlitz eines in der Fassade festgelegten Kunststoffprofils eingedrückt und dort in elastischem Formschluß lösbar gehalten ist.This object is achieved according to the invention in that the panel-shaped wall elements, preferably the parapet parts located below the windows, each have a circumferential, perpendicular to the facade level retaining leg in their edge area on their side facing the building, which at its free edge in a thickened terminal strip passes, which is pressed into an undercut clamping slot of a plastic profile fixed in the facade and is detachably held there in an elastic positive connection.
Erfindungsgemäß werden also neben dem Fensterbereich auch vorzugsweise die unterhalb der Fenster liegenden Wandflächen in den Druckentlastungsbereich mit einbezogen. Zur Montage werden die Wandelemente senkrecht zur Fassadenebene in die Kunststoffprofile eingedrückt, die aus Gummi, Neopren o.dgl. bestehen können und an der Fassade so festgelegt sind, daß sie auch dann ihre ursprüngliche Lage beibehalten, wenn bei einem plötzlichem Druckantieg die Wandelemente aus ihrer Klemmhalterung herausgedrückt werden. Dabei ist der elastische Formschluß vorzugsweise so ausgelegt, daß sich das Wandelement bei einem Rauminnendruck von 0,05 bis 0,1 bar löst.According to the invention, in addition to the window area, the wall areas below the window are preferably also included in the pressure relief area. For assembly, the wall elements are pressed perpendicular to the facade level into the plastic profiles made of rubber, neoprene or the like. can exist and are set on the facade so that they maintain their original position even if the wall elements are pressed out of their clamp bracket in the event of a sudden pressure rise. The elastic form fit is preferably designed so that the wall element is released at an internal pressure of 0.05 to 0.1 bar.
In einer zweckmäßigen Ausgestaltung kann die Klemmleiste im Querschnitt gesehen in Eindrückrichtung eine steile Anlaufschräge aufweisen, die in eine entgegengesetzt verlaufende flache Ablaufschräge übergeht, welche von einer Klemmlippe des Kunststoffprofils hintergriffen wird, die in einen sich zur Fassadenaußenseite konisch erweiternden Einschubschlitz übergeht. Dadurch ist einerseits ein leichtes Eindrücken der Klemmleiste in ihren elastischen Formschluß gewährleistet. Andererseits aber wird in überraschender Weise erreicht, daß dieser elastische Formschtttß die an dem Wandelement angreifenden Wind-Sog-Kräfte aufnimmt, sich aber bei Erreichen eines bestimmten Rauminnendruckes nahezu schlagartig löst. Dieser Effekt kann zusätzlich dadurch sichergestellt werden, daß die Klemmlippe einen in Auszugsrichtung hinter ihr angeordneten, allseitig umschlossenen Profilhohlraum begrenzt. Dadurch wird einerseits eine ausreichende Festigkeit und andererseits eine ausreichende Flexibilität der Klemmlippe sichergestellt.In an expedient embodiment, the terminal strip, seen in cross-section in the pushing-in direction, can have a steep run-up slope which merges into an oppositely running flat run-off slope, which is gripped by a clamping lip of the plastic profile, which merges into an insertion slot which widens conically towards the outside of the facade. On the one hand, this ensures that the terminal strip is easily pressed into its elastic form fit. On the other hand, however, it is surprisingly achieved that this elastic shape absorbs the wind suction forces acting on the wall element, but dissolves almost suddenly when a certain internal pressure is reached. This effect can also be ensured by the fact that the clamping lip delimits a profile cavity which is arranged behind it in all directions on the pull-out direction. This ensures sufficient strength on the one hand and sufficient flexibility of the clamping lip on the other.
In einer zweckmäßigen Weiterentwicklung kann das Kunststoffprofil eine erste Dichtlippe aufweisen, die den Halteschenkel des Wandelementes zur Außenseite abdeckt und am Rand des Wandelementes anliegt. Zusätzlich kann das Kunststoffprofil noch eine zweite Dichtlippe aufweisen, die den Halteschenkel des Wandelementes zur Innenseite abdeckt und gegen die Innenfläche des Wandelementes anliegt. Das Kunststoffprofil dient somit nicht nur Halterung eines Wandelementes, sonder auch zu dessen Abdichtung. Gleichzeitig bildet das erfindungsgemäße Kunststoffprofil eine hervorragende Schalldämpfung. Der Halteschenkel des Wandelementes ist von den Dichtlippen des Kunststoffprofils allseitig abgedeckt, wobei weder die Befestigung noch die Abdichtung von außen sichtbar sind, so daß sich eine optisch ansprechende Lösung ergibt. Außerdem liegen die Kunststoffprofile und damit auch deren Dichtlippen geschützt vor der Sonnenbestrahlung.In an expedient further development, the plastic profile can have a first sealing lip have, which covers the holding leg of the wall element to the outside and abuts the edge of the wall element. In addition, the plastic profile can also have a second sealing lip which covers the holding leg of the wall element on the inside and bears against the inner surface of the wall element. The plastic profile thus serves not only to hold a wall element, but also to seal it. At the same time, the plastic profile according to the invention forms excellent sound absorption. The retaining leg of the wall element is covered on all sides by the sealing lips of the plastic profile, with neither the fastening nor the sealing being visible from the outside, so that there is a visually appealing solution. In addition, the plastic profiles and thus their sealing lips are protected from the sun's rays.
Das Kunststoffprofil ist vorzugsweise in einem Metallprofil gehalten. Letzteres kann einen U-förmigen Querschnitt aufweisen, wobei an den freien Rändern der beiden U-Schenkel jeweils eine rechtwinklige Hinterschneidung zur Halterung des Kunststoffprofils vorgesehen sein kann. Dadurch läßt sich einerseits das Kunststoffprofil in einfacher Weise montieren, andererseits wird sichergestellt, daß das Kunststoffprofil beim Lösen des Wandelementes nicht ebenfalls aus dem Metallprofil herausgezogen wird.The plastic profile is preferably held in a metal profile. The latter can have a U-shaped cross-section, with a rectangular undercut for holding the plastic profile being provided on the free edges of the two U-legs. In this way, on the one hand, the plastic profile can be installed in a simple manner, on the other hand it is ensured that the plastic profile is not also pulled out of the metal profile when the wall element is released.
Der Halteschenkel kann Teil eines auf der Innenseite des Wandelementes befestigten Winkelprofils sein. Außerdem können die Wandelemente in ihrem Randbereich ausgeklinkt sein, so daß der lichte Abstand zwischen der Haltekonstruktion und den Wandelementen verringert werden kann.The holding leg can be part of an angle profile fastened on the inside of the wall element. In addition, the wall elements can be released in their edge area, so that the clear distance between the holding structure and the wall elements can be reduced.
Die Klemmleiste des Halteschenkels kann kammartige Einschnitte aufweisen. Dadurch wird die Halterungslänge der Klemmleiste im Kunststoffprofil verringert. Durch Wahl der Anzahl und/oder Läge der Einschnitte in Profillängsrichtung läßt sich die Klemmverbindung in einfacher Weise verschiedenen Druckverhältnissen anpassen.The clamping strip of the holding leg can have comb-like incisions. This will reduce the length of the bracket in the plastic profile. By choosing the number and / or length of the incisions in the longitudinal direction of the profile, the clamp connection can be easily adapted to different pressure conditions.
