Description

Die Erfindung betrifft ein Verbundprofil für Brandschutzverglasungen gemäss Oberbegriff des Anspruchs 1.The invention relates to a composite profile for fire-resistant glazings according to the preamble of claim 1.

Bei Brandschutzverglasungen handelt es sich um Verglasungen, die nicht nur die Ausbreitung von Feuer und Rauch sondern aufgrund ihres Feuerwiderstands auch die Ausbreitung von Wärme verhindern können (siehe beispielsweise DIN 4102 und DIN EN 13501). Die bei Brandschutzverglasungen verwendeten Brandschutzscheiben sind in der Regel mehrlagig, wobei zwischen den Glasscheiben jeweils eine Brandschutzschicht angeordnet ist. Bei der Brandschutzschicht handelt es sich typischerweise um eine intumeszierende Funktionsschicht, die im Brandfall aufschäumt und eine Schutzschicht z.B. in Form von Hartschaum bildet (siehe beispielsweise die europäische Patentanmeldung EP 1 637 687 A2 ).Fire-resistant glazings are glazings that can prevent not only the spread of fire and smoke but also the spread of heat due to their fire resistance (see, for example, DIN 4102 and DIN EN 13501). The fire protection windows used in fire-resistant glazing are usually multi-layered, with a fire protection layer being arranged between the glass panes. The fire protection layer is typically an intumescent functional layer which foams in the event of fire and forms a protective layer, for example in the form of rigid foam (see, for example, the European patent application EP 1 637 687 A2 ).

DE 34 18 470 A1 offenbart ein ähnliches Profil, bei dem ein nicht-wärmebeständiger Abstandhalter für einen Spannungsausgleich im Brandfall sorgt, welches alle Merkmale des Oberbegriffs des Anspruchs 1 offenbart. DE 34 18 470 A1 discloses a similar profile in which a non-heat-resistant spacer provides tension compensation in the event of a fire, which discloses all the features of the preamble of claim 1.

Es ist Aufgabe der Erfindung, ein Verbundprofil für Brandschutzverglasungen bereitzustellen, welches als Rahmen für eine Brandschutzverglasung bzw. deren Brandschutzscheiben eingesetzt werden kann und welches auch im Brandfalle seine Funktion als Rahmen weitestgehend beibehält, also thermostabil ist.It is an object of the invention to provide a composite profile for fire-resistant glazing, which can be used as a framework for fire-resistant glazing or their fire protection and which also largely retains its function as a frame in case of fire, so is thermostable.

Diese Aufgabe wird durch ein Verbundprofil mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a composite profile with the features of claim 1.

Das erfindungsgemässe Verbundprofil für Brandschutzverglasungen umfasst mehrere zusammengesteckte Verbundprofilsegmente. Jedes Verbundprofilsegment weist ein erstes und ein zweites Profilblech auf, die über wenigstens einen Steg miteinander verbunden sind. Ferner ist an jedem Profilblech ein Verbindungselement zur Herstellung einer Steckverbindung mit einem benachbarten Verbundprofilsegment vorgesehen. An einer Wand eines jeden Verbindungselements - vorzugsweise an einer Innenwand eines jeden Verbindungselements - ist ein nichtwärmebeständiger Abstandshalter zur Beabstandung zweier benachbarter, zusammengesteckter Verbundprofilsegmente angeordnet.The composite profile according to the invention for fire-resistant glazing comprises a plurality of assembled composite profile segments. Each composite profile segment has a first and a second profile sheet, which are interconnected via at least one web. Further, a connecting element for producing a plug connection with an adjacent composite profile segment is provided on each profile sheet. On a wall of each Connecting element - preferably on an inner wall of each connecting element - a non-heat-resistant spacer for spacing two adjacent, assembled composite profile segments is arranged.

Die nicht-wärmebeständigen Abstandshalter bestehen vorzugsweise aus einem Material, dessen Schmelzpunkt bei wenigstens 100 Grad Celsius liegt. Vorzugsweise bestehen die nicht-wärmebeständigen Abstandshalter aus einem Kunststoff, insbesondere einem thermoplastischen Kunststoff wie beispielsweise Polyvinylchlorid (PVC). Die Profilbleche bestehen vorzugsweise aus Chrom-Nickel-Stahl (CNS). Entsprechend bestehen die Stege und die Verbindungselemente vorzugsweise aus Chrom-Nickel-Stahl.The non-heat resistant spacers are preferably made of a material whose melting point is at least 100 degrees Celsius. Preferably, the non-heat-resistant spacers made of a plastic, in particular a thermoplastic such as polyvinyl chloride (PVC). The profile sheets are preferably made of chrome-nickel steel (CNS). Accordingly, the webs and the connecting elements are preferably made of chromium-nickel steel.

Bei dem erfindungsgemässen Verbundprofil handelt es sich insbesondere um ein Eckprofil. Hierzu sind das erste Profilblech und das zweite Profilblech eines jeden Verbundprofilsegments bevorzugterweise gekantet ausgeführt, wobei der Kantenwinkel des ersten Profilblechs dem Kantenwinkel des zweiten Profilblechs entspricht und vorzugsweise im Bereich von 90 bis 135 Grad liegt, wobei aber auch jeder kleinere oder grössere Winkel möglich ist. Entsprechend sind die an den Profilblechen vorgesehenen Verbindungselemente bevorzugt entsprechend der Profilbleche gekantet. Auf jeder Seite der sich durch Zusammenstecken der die Profilbleche umfassenden Verbundprofilsegmente ergebenden Kante des Verbundprofils kann dann eine Brandschutzscheibe in das Verbundprofil eingeschoben werden und zwar in den Zwischenraum zwischen den ersten und den zweiten Profilblechen. D.h. über das vorzugsweise als Eckprofil ausgebildete Verbundprofil können zwei in einem Winkel zueinander angeordnete Brandschutzscheiben miteinander verbunden werden. Das erfindungsgemässe Verbundprofil bildet hierbei eine Rahmen bzw. ein Rahmenteil für die Brandschutzscheiben.The composite profile according to the invention is, in particular, a corner profile. For this purpose, the first profiled sheet and the second profiled sheet of each composite profile segment are preferably formed folded, wherein the edge angle of the first profile sheet corresponds to the edge angle of the second profile sheet and preferably in the range of 90 to 135 degrees, but also any smaller or larger angle is possible. Accordingly, the provided on the profile plates connecting elements are preferably folded according to the profile sheets. On each side of the profile of the profiled sheet composite profile segments resulting edge of the composite profile can then be inserted into the composite profile and in the space between the first and the second profile sheets a fire protection pane. That About the preferably formed as a corner profile composite profile two fire shields arranged at an angle to each other can be connected to each other. The composite profile according to the invention in this case forms a frame or a frame part for the fire protection windows.

Im Brandfalle schmelzen die nicht-wärmebeständigen Abstandshalter des erfindungsgemässen Verbundprofils weg. Ferner dehnen bzw. verformen sich die Profilbleche der zusammengesteckten Verbundprofilsegmente unter der Hitzeeinwirkung. Da die Abstandshalter zwischen den Profilblechen benachbarter Verbundprofilsegmente aufgrund der Hitze weggeschmolzen sind, ergibt sich in Längsrichtung des Verbundprofils genügend Raum für eine Dehnung/Verformung der Profilbleche, sodass das erfindungsgemässe Verbundprofil seine Form im Wesentlichen behält. Das erfindungsgemässe Verbundprofil ist somit im Wesentlichen thermostabil. Die Verbindung zwischen den einzelnen Verbundprofilsegmenten bleibt bestehen. Ein Aufreissen bzw. Aufbrechen des Verbundprofils, was ein Ausbrechen des Feuers und somit eine Ausbreitung des Brandes und ausserdem erhöhte Unfallgefahr durch herabfallende Teile zur Folge hätte, kann mit dem erfindungsgemässen Verbundprofil vorteilhafterweise verhindert werden.In case of fire, the non-heat-resistant spacers of the invention melt Composite profile away. Furthermore, the profile sheets of the assembled composite profile segments stretch or deform under the effect of heat. Since the spacers are melted away between the profile sheets of adjacent composite profile segments due to the heat, sufficient space for elongation / deformation of the profile sheets in the longitudinal direction of the composite profile, so that the composite profile according to the invention essentially retains its shape. The composite profile according to the invention is therefore essentially thermostable. The connection between the individual composite profile segments remains. A tearing open or rupture of the composite profile, which would result in the fire breaking out and thus a spread of the fire and also an increased risk of accidents due to falling parts, can advantageously be prevented with the composite profile according to the invention.

Die Stege, die die beiden Profilbleche eines jeden Verbundprofilsegments miteinander verbinden, weisen vorzugsweise eine geringe Querschnittsfläche auf, die insbesondere im Bereich von 4 bis 6 mm2 liegt, wobei die Querausdehnung eines Steges vorzugsweise im Bereich von 2 bis 2.5 mm liegt. Durch die geringe Querschnittsfläche kommt den Stegen eine Isolierwirkung zu. Dies insbesondere, da die Profilbleche als Kühlflächen fungieren, welche die Wärme ableiten.The webs which connect the two profiled sheets of each composite profile segment with each other, preferably have a small cross-sectional area, which is in particular in the range of 4 to 6 mm 2 , wherein the transverse extent of a web is preferably in the range of 2 to 2.5 mm. Due to the small cross-sectional area, the bars have an insulating effect. This in particular, since the profile sheets act as cooling surfaces, which dissipate the heat.

Die Profilbleche 3, 4 sind parallel zueinander und gleich ausgerichtet angeordnet, d.h. die Kante des Profilblechs 4 weist nach innen, während die Kante des Profilblechs 3 nach aussen weist. Entsprechend sind die Stege 5 vorzugsweise in der Form von Pfeilen ausgeführt, deren Pfeilspitze und deren Pfeilende jeweils eine Ecke mit einem Winkel von 90 Grad bilden, sodass der Steg 5 mit dem Pfeilende auf das Profilblech 4 und mit der Pfeilspitze auf das Profilblech 3 - vorzugsweise durch Schweissen - aufgebracht werden kann.

Für die Herstellung der Steckverbindung wird ein benachbarten Verbundprofilsegment 2 in den durch die Verbindungselemente 6 der Profilbleche 3, 4 gebildeten Zwischenraum geschoben wird. Dabei ist der Abstand der Verbindungselemente 6 (in Querrichtung gesehen) und der Abstand zwischen den Profilblechen 3, 4 derart gewählt, dass sich die Profilbleche 3, 4 eines benachbarten Verbundprofilsegments 3, 4 passgenau bzw. formschlüssig in den Zwischenraum zwischen den Verbindungselementen 6 eines Verbundprofilsegments 2 einbringen lassen. Die Verbindungselemente 6 sind entsprechend der Profilbleche 3, 4 gekantet, d.h. beispielhaft in einem Winkel von 90 Grad. Die Verbindungselemente 6' der Verbundprofilsegmente 2' gemäss der Figuren 3 und 4 sind entsprechend der Profilbleche 3', 4' in einem Winkel von 135 Grad gekantet.The connecting elements 6 serve to produce a plug connection of a composite profile segment 2 with an adjacent composite profile segment 2. For the production of the plug connection, an adjacent composite profile segment 2 is pushed into the intermediate space formed by the connecting elements 6 of the profiled sheets 3, 4. Here, the distance of the connecting elements 6 (seen in the transverse direction) and the distance between the profiled sheets 3, 4 chosen such that the profiled sheets 3, 4 of an adjacent composite profile segment 3, 4 fit or form fit into the space between the connecting elements 6 of a composite profile segment 2 bring in. The connecting elements 6 are folded according to the profile sheets 3, 4, that is, for example, at an angle of 90 degrees. The connecting elements 6 'of the composite profile segments 2' according to the Figures 3 and 4 are according to the profile sheets 3 ', 4' folded at an angle of 135 degrees.

Auf der Innenwand eines jeden Verbindungselements 6 (und entsprechend eines jeden Verbindungselements 6') sind Abstandshalter 7 angeordnet (siehe Figuren 2 und 4), die in Richtung auf das jeweils andere Verbindungselement 6 und somit in den Innenraum des jeweiligen Verbundprofilsegments 2 ragen, Auf jeder Seite der Kante/Ecke eines Verbindungselements 6 ist vorzugsweise ein Abstandshalter 7 angeordnet, wobei die Abstandshalter 7 auf gleicher Höhe angeordnet sind. Die Abstandshalter 7 können beispielsweise auf die Verbindungselemente 6 aufgeklebt sein und bestehen aus nicht-wärmebeständigem Material wie z.B. einem thermoplastischen Kunststoff. In den Figuren 1 und 3 sind die Abstandshalter 7 der Einfachheit der Darstellung halber weggelassen.On the inner wall of each connecting element 6 (and corresponding to each connecting element 6 ') spacers 7 are arranged (see Figures 2 and 4 ), which protrude in the direction of the respective other connecting element 6 and thus in the interior of the respective composite profile segment 2, on each side of the edge / corner of a connecting element 6, a spacer 7 is preferably arranged, wherein the spacers 7 are arranged at the same height. The spacers 7 may for example be glued to the connecting elements 6 and consist of non-heat-resistant material such as a thermoplastic material. In the FIGS. 1 and 3 For reasons of simplicity, the spacers 7 have been omitted.

Wird ein Verbundprofilsegment 2 mit einem benachbarten Verbundprofilsegment 2 verbunden, indem die Profilbleche 3, 4 des einen Verbundprofilsegments 2 in den Zwischenraum zwischen den Verbindungselementen 6 des anderen, benachbarten Verbundprofilsegments 2 geschoben werden, so stossen die Profilbleche 3, 4 des einen Verbundprofilsegments 2 an die Abstandshalter 7 des anderen, benachbarten Verbundprofilsegments 2 an, sodass die Profilbleche 3, 4 zweier benachbarter Verbundprofilsegmente 2 des Verbundprofils 1 in Längsrichtung beabstandet zueinander angeordnet sind.If a composite profile segment 2 is connected to an adjacent composite profile segment 2 by the profiled sheets 3, 4 of a composite profile segment 2 in the gap between the connecting elements 6 of the other, adjacent composite profile segment 2 are pushed, the profile sheets 3, 4 of a composite profile segment 2 abut the spacers 7 of the other, adjacent composite profile segment 2, so that the profile sheets 3, 4 two adjacent composite profile segments 2 of the composite profile 1 are arranged spaced apart in the longitudinal direction.

Zur optischen Abdeckung können aussen auf der Vorderseite und auf der Rückseite der Verbundprofilsegmente 2 bzw. auf dem gesamten Verbundprofil 1 sich in Längsrichtung erstreckende Abdeckbleche 8 vorgesehen sein, die beispielsweise mittels Schnapp- oder Klebeverbindung auf die Profilbleche 3, 4 und/oder die Verbindungselemente 6 aufgeschnappt oder -geklebt werden. Die Abdeckbleche 8 sind dazu wie die Profilbleche 3, 4 gekantet und weisen an ihren Längsseiten längliche Haken 9 auf, die beim Aufbringen auf die Profilbleche 3, 4 und auf die Verbindungselemente 6 die Längsseiten der Profilbleche 3, 4 und/oder der Verbindungselemente 6 aufnehmen.For optical coverage outside on the front and on the back of the composite profile segments 2 or on the entire composite profile 1 extending in the longitudinal direction cover plates 8 may be provided, for example, by snap or adhesive connection to the profile sheets 3, 4 and / or the connecting elements. 6 be snapped or glued. The cover plates 8 are like the profile sheets 3, 4 folded and have on their longitudinal sides elongated hooks 9, which receive the longitudinal sides of the profile sheets 3, 4 and / or the connecting elements 6 when applied to the profile sheets 3, 4 and on the connecting elements 6 ,

Bei einem Brand schmelzen die nicht-wärmebeständigen Abstandshalter 7 weg, sodass sich in Längsrichtung des Verbundprofils 1 Raum für die Profilbleche 3, 4 ergibt, in den hinein sie sich ausdehnen können. Dadurch kann eine Verformung, insbesondere ein Aufreissen, des Verbundprofils 1 vermieden werden. Das Verbundprofil 1 ist also thermostabil und kann einer Ausbreitung des Brandes entgegenwirken.In a fire, the non-heat-resistant spacers 7 melt away, so that in the longitudinal direction of the composite profile 1 space for the profile sheets 3, 4 results, in which they can expand. As a result, deformation, in particular tearing, of the composite profile 1 can be avoided. The composite profile 1 is therefore thermostable and can counteract the spread of fire.

Bezüglich des in den Figuren 3 und 4 dargestellten Verbundprofils 1' (bzw. dessen Verbundprofilsegmenten 2'), welches ebenfalls als Eckprofil ausgestaltet ist jedoch mit einem Winkel von 135 Grad, und dessen Profilblechen 3', 4', Verbindungselementen 6', Stegen 5' und Abdeckblechen 8' etc. gilt das oben Gesagte entsprechend.Regarding the in the Figures 3 and 4 illustrated composite profile 1 '(or its composite profile segments 2'), which is also designed as a corner profile but with an angle of 135 degrees, and its profile sheets 3 ', 4', connecting elements 6 ', webs 5' and cover plates 8 'etc. applies the above said accordingly.
