Description

Rahmenelement in bevorzugt brandgeschützter Ausführung, insbesondere in Form einer Brandschutztür, bestehend aus einer inneren und einer äußeren Rahmenschale die beide auf Abstand miteinander verbunden sind und zwischen sich ein plattenförmiges Flächenelement, insbesondere ein Glaselement aufnehmen, sowie mit zum Flächenelement hin vorstehenden Halteleisten, auch in Form von lösbaren Glashalteleisten, die zwischen sich das Flächenelement halten, wobei die innere und die äußere Rahmenschale zusätzlich über wenigstens einen brandresistenten Schalenverbinder miteinander verbunden sind.Frame element in a preferably fire-protected design, in particular in the form of a fire protection door, consisting of an inner and an outer frame shell, both of which are connected to one another at a distance and accommodate a plate-shaped surface element, in particular a glass element, and with retaining strips protruding towards the surface element, also in the form of detachable glazing beads, which hold the surface element between them, the inner and outer frame shells being additionally connected to one another via at least one fire-resistant shell connector.

Derartige Rahmenelemente sind in unterschiedlichen Ausführungsformen aus dem Stand der Technik bekannt, wobei der Schalenverbinder die Aufgabe hat, im Brandfall eine Trennung der beiden Rahmenschalen voneinander und damit ein Lösen des plattenförmigen Flächenelements zu verhindern. Für die Befestigung der Schalenverbinder bestehen unterschiedliche Möglichkeiten; häufig erfolgt ein Verschrauben an wenigstens einer der beiden Rahmenschalen, was beim Aufbau des Rahmenelements zu einem erhöhten Zeit- und Arbeitsaufwand führt. Derartige Rahmenelemente sind insbesondere aus DE 20 2006 004 606 U1 und EP 2 634 347 A1 bekannt. Auch EP 1 793 073 A2 beschreibt ein Gebäudeelement in brandgeschützter Ausführung.Frame elements of this type are known in various embodiments from the prior art, with the shell connector having the task of preventing the two frame shells from separating from one another in the event of a fire and thus preventing the plate-shaped surface element from becoming detached. There are different options for attaching the shell connectors; Frequently, at least one of the two frame shells is screwed together, which leads to an increased expenditure of time and work when constructing the frame element. Such frame elements are made in particular DE 20 2006 004 606 U1 and EP 2 634 347 A1 known. Also EP 1 793 073 A2 describes a building element in a fire-resistant design.

Der Erfindung liegt die Aufgabe zugrunde, ein Rahmenelement der eingangs genannten Art so zu verbessern, dass der Schalenverbinder auf einfache Weise montiert werden kann, gleichwohl aber im Brandfall eine optimale Funktions- und Schutzwirkung entfaltet.The object of the invention is to improve a frame element of the type mentioned at the outset in such a way that the shell connector can be installed in a simple manner, but nevertheless develops an optimal functional and protective effect in the event of a fire.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Schalenverbinder als Blechwinkel ausgebildet ist, dessen erster Schenkel mit Halteklammern zur Befestigung an von den Rahmenschalen zum Flächenelement hin vorstehenden, vorzugsweise T-profilförmigen Anschlussleisten versehen ist, während der zweite Schenkel eine Anlagefläche für das Flächenelement bildet, wobei auf dem ersten Schenkel ein Stützschieber verschieb- und feststellbar angeordnet ist, der ein zum zweiten Schenkel des Schalenverbinders paralleles Stützblech für das Flächenelement aufweist und wobei der zweite Schenkel ebenfalls verschiebbar auf dem ersten Schenkel angeordnet und durch einen weiteren Stützschieber ausgebildet istAccording to the invention, this object is achieved in that the shell connector is designed as a sheet metal angle, the first leg of which is provided with retaining clips for attachment to preferably T-shaped connecting strips protruding from the frame shells to the surface element, while the second leg is a contact surface for the surface element forms, with a support slide being arranged on the first leg in a displaceable and lockable manner, which has a support plate parallel to the second leg of the shell connector for the surface element, and with the second leg also being arranged displaceably on the first leg and being formed by a further support slide

Der durch die Erfindung erreichte Vorteil besteht zunächst im Wesentlichen darin, dass der Schalenverbinder unmittelbar an den Anschlussleisten, zum Beispiel durch Aufrasten, angebracht werden kann, wodurch die beiden Rahmenschalen, insbesondere wenn diese durch hitzeempfindliche Dämmstege miteinander verbunden sind, auch im Brandfall zusammengehalten werden. Hinzukommt, dass der zweite Schenkel des Schalenverbinders gemeinsam mit dem Stützblech des Stützschiebers das Flächenelement klammerartig zwischen sich halten, wodurch ein zusätzlicher Schutz gegen Zerstörung des Rahmenelements im Brandfall, z.B. infolge hitzebedingter Krümmung des Flächenelements, gegeben ist.The advantage achieved by the invention consists essentially in the fact that the shell connector can be attached directly to the connection strips, for example by snapping it on, whereby the two frame shells are held together even in the event of fire, especially if they are connected to one another by heat-sensitive insulating webs. In addition, the second leg of the shell connector together with the support plate of the support slide hold the panel element between them in the manner of a clamp, which provides additional protection against destruction of the frame element in the event of fire, e.g. due to heat-induced curvature of the panel element.

In bevorzugter Ausführungsform der Erfindung sind die Halteklammern des Schalenverbinders derart ausgebildet, dass sie die Anschlussleisten jeweils auf ihren einander abgewandten Seiten umgreifen, wodurch die Möglichkeit besteht, den Schalenverbinder auf die T-profilförmige Anschlussleisten aufzurasten.In a preferred embodiment of the invention, the retaining clips of the shell connector are designed in such a way that they grip the terminal strips on their opposite sides, which makes it possible to snap the shell connector onto the T-profile-shaped terminal strips.

Es besteht im Rahmen der Erfindung jedoch auch die Möglichkeit, dass auf der dem zweiten Schenkel des Schalenverbinders abgewandten Seite eine zweite Halteklammervorgesehen ist und die Anschlussleiste zwischen diesen beiden Halteklammern aufgenommen ist. Damit wird eine erhöhte Stabilität insbesondere auch bei erhöhten mechanischen Belastungen sichergestellt.Within the scope of the invention, however, there is also the possibility that a second retaining clip is provided on the side facing away from the second leg of the shell connector and that the connection strip is accommodated between these two retaining clips. This ensures increased stability, especially in the case of increased mechanical loads.

Die Halteklammern können in besonders einfacher und daher im Rahmen der Erfindung bevorzugter Ausgestaltung am Rand des Schalenverbinders angeschlossen oder aus diesem freigeschnitten sein.In a particularly simple configuration, which is therefore preferred within the scope of the invention, the retaining clips can be connected to the edge of the shell connector or cut free from it.

Der Stützschieber umgreift den Rand des Schalenverbinders jeweils mit laschenförmig umgebogenen Führungsleisten, wodurch dieser auf dem Schalenverbinder verschoben werden kann.The support slide encompasses the edge of the shell connector in each case with guide strips bent over in the form of a lug, as a result of which it can be displaced on the shell connector.

Desweiteren ist der Schalenverbinder an seinen senkrecht zu den Rahmenschalen sich erstreckenden Rändern mit Sperrausnehmungen versehen, in die am Stützschieber vorgesehene, eine Rückstellung des Stützschiebers sperrende Rastzungen eingreifen. Hierdurch besteht die Möglichkeit, den Stützschieber zunächst so auf dem Schalenverbinder anzuordnen, dass der das Flächenelement zwischen sich aufnehmende Schenkel einerseits und das Stützblech andererseits zunächst maximalen Abstand voneinander aufweisen und nach Montage des Flächenelements der Stützschieber an das Flächenelement herangeschoben wird, worauf die Rastzungen den Stützschieber in dieser Position arretieren.Furthermore, the shell connector is provided with locking recesses on its edges extending perpendicularly to the frame shells, into which latching tongues provided on the support slide engage, locking a return of the support slide. This makes it possible to initially arrange the support slide on the shell connector in such a way that the leg holding the surface element between them on the one hand and the support plate on the other hand are initially at a maximum distance from one another and, after the surface element has been installed, the support slide is pushed towards the surface element, whereupon the locking tongues secure the support slide lock in this position.

Von Vorteil ist weiter, wenn der zweite Schenkel des Schalenverbinders in eine Nut der dem Flächenelement anliegenden Dichtleiste vorsteht und zusätzlich ein dazu parallel angebrachter Steg in eine Nut an einer der Glashalteleisten einsteht. Dabei kann diese Dichtleiste insbesondere eine den zweiten Schenkel hinreichend weit überlappende Dichtungslippe aufweisen, wodurch der Rand des zweiten Schenkels - durch Spiegelung im Glas - nicht sichtbar ist.It is also advantageous if the second leg of the shell connector protrudes into a groove in the sealing strip that rests on the surface element and a web that is attached parallel thereto projects into a groove on one of the glazing beads. In this case, this sealing strip can in particular have a sealing lip that sufficiently overlaps the second leg, as a result of which the edge of the second leg is not visible—due to reflection in the glass.

Von besonderem Vorteil bzw. Wirkung ist der Schalenverbinder bei Rahmenschalen, die über Isolierstege miteinander verbunden sind; grundsätzlich ist der Einsatz jedoch auch dann möglich, wenn die Rahmenschalen über feste Rahmenprofilteile miteinander verbunden sind.The shell connector is of particular advantage and effect for frame shells that are connected to one another via insulating bars; in principle, however, it can also be used if the frame shells are connected to one another via fixed frame profile parts.

Erfindungsgemäß ist der zweite Schenkel des Schalenverbinders ebenfalls verschiebbar durch einen weiteren Stützschieber ausgebildet.According to the invention, the second leg of the shell connector is also designed to be displaceable by means of a further support slide.

Schließlich ist das Rahmenelement derart gestaltet, dass die das Flächenelement haltenden Glasleisten sich an den die Schalenverbinder tragenden Anschlussleisten mit einem teilweise offenen, hohlförmigen Rundprofil abstützen. In den Bereichen, in denen Schalenverbinder an den Anschlussleisten angeschlossen sind, weisen diese jedoch - bedingt durch den Schalenverbinder - eine größer Breite auf, so dass dort die Anbringung der Glasleiste erschwert sein kann. Daher sieht die Erfindung für die Vereinfachung der Montage der Glasleisten ein Verfahren vor, bei welchem der Schalenverbinder auf die Anschlussleisten aufgeclipst oder aufgesetzt und danach durch Umbiegen der Halteklammern befestigt wird, wobei anschließend die Halteklammer auf der der Glasleiste zugewandten Seite zusammen mit der Anschlussleiste derart umgeformt wird, dass sich für die Glasleiste die gleiche Abstützposition wie ohne aufgesetzten Schalenverbinder ergibt. Dadurch ist die Montage der Glasleiste in gleicher Weise möglich wie ohne angebrachte Halteklammer.Finally, the frame element is designed in such a way that the glazing beads holding the surface element are supported on the connecting beads carrying the shell connectors with a partially open, hollow round profile. However, in the areas in which shell connectors are connected to the connection strips, these have a greater width - due to the shell connector - so that it can be difficult to attach the glazing strip there. The invention therefore provides a method for simplifying the assembly of the glazing beads, in which the shell connector is clipped or placed onto the connecting strips and then fastened by bending the retaining clips, with the retaining clip then being deformed on the side facing the glazing bead together with the connecting strip in this way that the glazing bead has the same support position as without the shell connector fitted. This means that the glazing bead can be mounted in the same way as without the retaining clip attached.

Im Folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; es zeigen:

Das in der Zeichnung nur teilweise wiedergegebene Rahmenelement ist in brandgeschützter Ausführung gezeigt und ist beispielsweise für eine Brandschutztür vorgesehen. Es besteht aus einer inneren 1 und einer äußeren 2 Rahmenschale, die beide auf Abstand miteinander verbunden sind und zwischen sich ein plattenförmiges Flächenelement, also beispielsweise ein Glaselement aufnehmen. Weiter sind zum Flächenelement 4 hin vorstehende Halteleisten 3 vorgesehen, von denen eine oder auch beide als lösbare Glashalteleisten ausgebildet sein können und zwischen sich das Flächenelement 4 halten.The frame element, which is only partially reproduced in the drawing, is shown in a fire-resistant design and is provided, for example, for a fire protection door. It consists of an inner 1 and an outer 2 frame shell, both of which are connected to one another at a distance and between them accommodate a plate-shaped surface element, for example a glass element. Next to the surface element 4 protruding retaining strips 3 are provided, one or both of which can be designed as detachable glass retaining strips and hold the surface element 4 between them.

Die innere und die äußere Rahmenschale 1, 2 sind zusätzlich durch wenigstens einen brandresistenten Schalenverbinder 5 miteinander verbunden. Dieser Schalenverbinders 5 ist als Blechwinkel ausgebildet, wobei der erste Schenkel 5.1 mit Halteklammern 6 versehen ist, die zur Befestigung an vorzugsweise T-profilförmigen Anschlussleisten 7 vorgesehen sind, die von den Rahmenschalen 1, 2 zum Flächenelement 4 hin vorstehen.The inner and outer frame shells 1, 2 are additionally connected to one another by at least one fire-resistant shell connector 5. This shell connector 5 is designed as a sheet metal angle, with the first leg 5.1 being provided with retaining clips 6 which are provided for attachment to preferably T-shaped connecting strips 7 which protrude from the frame shells 1, 2 towards the surface element 4.

Der zweite Schenkel 5.2 des Schalenverbinders 5 bildet dagegen eine Anlagefläche für das Flächenelement 4, wobei auf dem ersten Schenkel 5.1 ein Stützschieber 8 verschieb- und feststellbar angeordnet ist, der ein zum zweiten Schenkel 5.2 des Schalenverbinders 5 paralleles Stützblech 8.1 für das Flächenelement 4 aufweist. Während der Schalenverbinder 5 als solcher dafür sorgt, dass - im Brandfall - die beiden Rahmenschalen 1, 2 aneinander gehalten werden, sorgen der zweite Schenkel 5.2 des Schalenverbinders 5 zusammen mit dem Stützblech 8.1 des Stützschiebers 8 dafür, dass das Flächenelement 4 zusätzlich Halt erfährt, wodurch einer hitzebedingten Krümmung des Flächenelements entgegengewirkt wird.The second leg 5.2 of the shell connector 5, on the other hand, forms a contact surface for the surface element 4, with a support slide 8 being arranged on the first leg 5.1 in a displaceable and lockable manner, which has a support plate 8.1 for the surface element 4 parallel to the second leg 5.2 of the shell connector 5. While the shell connector 5 as such ensures that - in the event of fire - the two frame shells 1, 2 are held together, the second leg 5.2 of the shell connector 5 together with the support plate 8.1 of the support slide 8 ensure that the surface element 4 is additionally supported. whereby a heat-induced curvature of the surface element is counteracted.

Wie sich insbesondere aus der Figur 1 ergibt, umgreifen die Halteklammern 6 des Schalenverbinders 5 die Anschlussleisten 7 jeweils auf ihren einander abgewandten Seiten. Zusätzlich ist auf der dem zweiten Schenkel 5.2 des Schalenverbinders 5 abgewandten Seite eine zweite Halteklammer 6 vorgesehen, wodurch die Anschlussleiste 7 zwischen diesen beiden Halteklammern 6 aufgenommen ist.As can be seen in particular from the figure 1 As a result, the retaining clips 6 of the shell connector 5 encompass the terminal strips 7 on their opposite sides. In addition, a second retaining clip 6 is provided on the side facing away from the second leg 5 .

Wie aus der Figur 2 zu ersehen ist, sind die Halteklammern 6 am Rand des Schalenverbinders 5 angeschlossen bzw. aus diesem freigeschnitten.How from the figure 2 can be seen, the retaining clips 6 are connected to the edge of the shell connector 5 or cut free from this.

Der Stützschieber 8 ist gemäß Fig. 3 randseitig mit umgebogenen Laschen 9 versehen, die Führungsleisten für den Rand des Schalenverbinders 5 bilden.The support slide 8 is according 3 provided at the edge with bent tabs 9, which form guide rails for the edge of the shell connector 5.

Nach Einsetzen des Flächenelements 4 in den zunächst auf Abstand gehaltenen Schenkel 5.2 bzw. des Stützblech 8.1 wird das Stützblech 8.1 gegen den zweiten Schenkel 5.2 des Schalenverbinders 5 herangefahren. Um diesen dann in dieser Stellung zu halten, ist der Schalenverbinder 5 an seinen senkrecht zu den Rahmenschalen 1, 2 sich erstreckenden Rändern mit Sperrausnehmungen 10 versehen, in die am Stützschieber 8 vorgesehene Rastzungen 11 eingreifen, die dann ein Lösen bzw. Zurückfahren des Stützschiebers 8 sperren.After inserting the surface element 4 in the leg 5.2 or the support plate 8.1, which is initially kept at a distance, the support plate 8.1 is moved up against the second leg 5.2 of the shell connector 5. In order to then hold it in this position, the shell connector 5 is provided with locking recesses 10 on its edges extending perpendicularly to the frame shells 1, 2, into which latching tongues 11 provided on the support slide 8 engage, which then allow the support slide 8 to be released or moved back lock out.

Wie weiter aus der Figur 1 ersichtlich, steht der zweite Schenkel 5.2 des Schalenverbinders 5 in eine Nut 12 der dem Flächenelement 4 anliegenden Dichtleiste 13 vor, wodurch der Rand des Schenkels 5.2 abgedeckt, also von innen nicht sichtbar ist.How further from the figure 1 As can be seen, the second leg 5.2 of the shell connector 5 protrudes into a groove 12 of the sealing strip 13 adjacent to the surface element 4, whereby the edge of the leg 5.2 is covered, ie not visible from the inside.

Wie weiter aus der Fig. 1 hervorgeht, ist an dem zweiten Schenkel 5.2 ein dazu parallel angebrachter Steg 5.3 vorhanden, welcher in eine Nut 3.1 an einer der Glasleisten 3 einsteht.How further from the 1 shows that on the second leg 5.2 there is a web 5.3 attached parallel thereto, which protrudes into a groove 3.1 on one of the glazing beads 3.

Bei dem in der Figur 1 dargestellten Rahmenelement sind die beiden Rahmenschalen 1, 2 über Isolierstege 14 miteinander verbunden; grundsätzlich kann der Schalenverbinder 5 jedoch auch bei solchen Rahmenelementen eingesetzt werden, bei denen die Rahmenschalen 1,2 über feste Rahmenprofilteile 15 miteinander verbunden sind, wie dies aus der Figur 5 hervorgeht.At the in the figure 1 frame element shown, the two frame shells 1, 2 are connected to one another via insulating bars 14; In principle, however, the shell connector 5 can also be used in those frame elements in which the frame shells 1.2 are connected to one another via fixed frame profile parts 15, as can be seen from FIG figure 5 emerges.

In Fig. 4 ist eine erfindungsgemäße Ausgestaltung des Schalenverbinders 5 gezeigt, mit dessen Hilfe es möglich ist, zwei Stützschieber 8 zu verwenden, die dann beidseits desIn 4 an inventive embodiment of the shell connector 5 is shown, with the help of which it is possible to use two support slides 8, which are then on both sides of the

Flächenelements 4 anliegen und eine flexiblere Anpassung statt des starren Schenkels 5.2 ermöglichen.Abut surface element 4 and allow a more flexible adjustment instead of the rigid leg 5.2.

Für die Befestigung der Glasleisten dienen ebenfalls die die Schalenverbinder 5 tragenden Anschlussleisten 7, an denen sich die Glasleisten 3 mit einem teilweise - zur Anschlussleiste 7 hin - offenen, hohlförmigen Rundprofil 16 abstützen. Wie sich aus der Figur 1 erkennen lässt, kann die Montage der Glasleisten 3 dann erschwert sein, wenn die Halteklammern 6 eine Größe oder Form besitzen, die eine Aufnahme innerhalb des hohlförmigen Rundprofils 16 nicht mehr erlauben.The connection strips 7 carrying the shell connectors 5 are also used for fastening the glazing beads, on which the glazing beads 3 are supported with a partially open, hollow round profile 16--towards the connection strip 7. As emerges from the figure 1 recognize leaves, the assembly of the glazing beads 3 can then be more difficult if the retaining clips 6 have a size or shape that no longer allow recording within the hollow round profile 16.

Der in der Fig. 4 gezeigte Schalenverbinder 5 kann in einer nicht beanspruchten Ausführungsform auch gänzlich ohne Stützschieber 8.1 bzw. ohne Stützblech 5.2 eingesetzt werden, insbesondere bei Blendrahmen oder Festfeldern auf der den Halteleisten 3 abgewandten Seite, also auf der Laibungsseite, da dort kein Raum für einen Stützschieber 8.1 bzw. ein Stützblech 5.2 ist; gleichwohl wird dadurch eine brandresistente Wirkung erreicht.The Indian 4 In an embodiment that is not claimed, the shell connector 5 shown can also be used entirely without a support slide 8.1 or without a support plate 5.2, particularly in the case of blind frames or fixed panels on the side facing away from the retaining strips 3, i.e. on the reveal side, since there is no space for a support slide 8.1 or is a support plate 5.2; nevertheless, this achieves a fire-resistant effect.

In diesem Fall kommt ein Verfahren zum Einsatz, bei welchem zunächst die Schalenverbinder 5 auf die Anschlussleisten 7 aufgeclipst oder aufgesetzt und durch Umbiegen der Halteklammern 6 befestigt werden, worauf die Halteklammer 6 auf der der Glasleiste 3 zugewandten Seite zusammen mit der Anschlussleiste 7 derart umgeformt wird, dass sich für die Glasleiste die gleiche Abstützposition wie ohne aufgesetzten Schalenverbinder ergibt. Dies ist im Einzelnen aus den Darstellungen der Figur 5 ersichtlich.In this case, a method is used in which the shell connectors 5 are first clipped or placed onto the connection strips 7 and fastened by bending the retaining clips 6, whereupon the retaining clip 6 is shaped on the side facing the glazing strip 3 together with the connection strip 7 in this way that the glazing bead has the same support position as without the shell connector fitted. This is in detail from the representations of figure 5 evident.
