A layer of intumescent material is arranged between the holder and frame, and expands when a threshold temperature is exceeded to press the holder against the surface panel.

Description

Die vorliegende Erfmdung betrifft eine Rahmenkonstruktion für Brandschutzelemente, mit einem Rahmen, in dem ein plattenförmiges Flächenelement gehalten ist, wobei zwischen dem Rahmen und dem Flächenelement mindestens ein metallischer Halter vorgesehen ist, der das Flächenelement umgreift und am Rahmen gehalten ist.The present invention relates to a frame construction for fire protection elements, with a frame in which a plate-shaped surface element is held, wherein between the frame and the surface element at least one metallic holder is provided which engages around the surface element and is held on the frame.

Aus der DE 30 09 729 ist eine Rahmenkonstruktion bekannt, bei der eine Brandschutzverglasung in einem Rahmen festgelegt ist, wobei für die Sicherung für den Brandfall eine Glashalteleiste am Rahmen montiert ist, die aus einem schwer brennbaren Material besteht und die Brandschutzverglasung gegen ein Herausfallen im Brandfall sichert, wofür Stahlhaltewinkel so angeordnet sind, dass sie durch Schrauben an dem Profil festgelegt sind. Im Brandfall besteht allerdings das Problem, dass durch die Temperatureinwirkung eine starke flächige Durchbiegung zum Brandraum hin auftritt. Die Durchbiegung bedeutet im Scheibenrandbereich, dass sich die Scheibenränder vom Rahmen weg hin zur Scheibenmitte bewegen und so die Überdeckung mit der am Rahmen festgelegten Halterung abnimmt, bis im oberen und in den seitlichen Bereichen keine Überdeckung mehr gegeben ist und die Brandschutzgläser nicht mehr sicher gehalten werden können.From the DE 30 09 729 a frame construction is known in which a fire-resistant glazing is set in a frame, which is mounted for securing a fire in the glazing bead on the frame, which consists of a flame-retardant material and the fire-resistant glazing secures against falling out in case of fire, for which steel brackets arranged so are that they are fixed by screws on the profile. In case of fire, however, there is the problem that due to the effect of temperature a strong area deflection occurs towards the fire area. Deflection at the edge of the disc means that the edges of the disc move away from the frame towards the center of the disc, thus decreasing the overlap with the holder fixed to the frame until there is no overlap in the upper and lateral areas and the safety glasses are no longer securely held can.

Das Dokument EP 1 327 739 A2 zeigt eine ähnliche Rahmenkonstruktion mit allen Merkmalen des Oberbegriffs des Anspruchs 1.The document EP 1 327 739 A2 shows a similar frame construction with all features of the preamble of claim 1.

Es ist daher Aufgabe der vorliegenden Erfindung eine Rahmenkonstruktion für Brandschutzelemente zu schaffen, die einfach aufgebaut ist und auch bei einer Durchbiegung des Flächenelementes eine sichere Halterung am Rahmen gewährleistet.It is therefore an object of the present invention to provide a frame structure for fire protection elements, which is simple and ensures a secure mounting on the frame even with a deflection of the surface element.

Diese Aufgabe wird mit einer Rahmenkonstruktion mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a frame construction with the features of claim 1.

Erfindungsgemäß ist zwischen dem Rahmen und dem Flächenelement ein Halter vorgesehen, der in eine Richtung vom Rahmen zum Flächenelement hin bewegbar am Rahmen gehalten ist und bei einer Bewegung des Flächenelementes vom Rahmen weg das Flächenelement durch den Halter am Rahmen gesichert ist. Dadurch können Relativbewegungen zwischen dem Flächenelement und dem Rahmen ausgeglichen werden, indem der Halter als eine Art Überbrückungselement für die mechanische Halterung des Flächenelementes am Rahmen sorgt. Damit können auch Extremsituationen, wie im Brandfall, zuverlässig gemeistert werden, ohne dass die Gefahr besteht, dass das Flächenelement aus dem Rahmen herausfällt. Der Halter kann dabei im Normalzustand ohne Funktion und unsichtbar zwischen Rahmen und Flächenelement verbleiben und im Brandfall bei einer Bewegung des Flächenelementes innerhalb des Rahmens die Funktion der Halterung übernehmen.According to the invention, a holder is provided between the frame and the surface element, which is held in a direction from the frame to the surface element movable on the frame and the surface element is secured by the holder on the frame during a movement of the surface element away from the frame. As a result, relative movements between the surface element and the frame can be compensated by the holder provides as a kind of bridging element for the mechanical support of the surface element on the frame. Thus even extreme situations, such as in case of fire, can be mastered reliably, without the risk that the surface element falls out of the frame. The holder can remain in the normal state without function and invisible between the frame and surface element and take over the function of the holder in case of fire during a movement of the surface element within the frame.

Vorzugsweise ist zwischen dem Halter und dem Rahmen eine Schicht aus intumeszierendem Material angeordnet, das bei Überschreiten einer Schwelltemperatur, beispielsweise 150 bis 200° C stark expandiert und den Halter gegen das Flächenelement drückt. Dadurch wird ein formschlüssiges Anliegen des bewegbaren Halters am Flächenelement im Brandfall gewährleistet. Statt der Schicht aus intumeszierendem Material könnte der Halter auch mittels Federn oder über die Schwerkraft gegen das Flächenelement gedrückt werden, bei dem intumeszierenden Material ergeben sich allerdings auch Montagevorteile und eine Expansion erfolgt nur im Brandfall ab einer vorbestimmten Temperatur.Preferably, a layer of intumescent material is arranged between the holder and the frame, which greatly expands when a threshold temperature, for example 150 to 200 ° C is exceeded, and presses the holder against the surface element. This ensures a positive engagement of the movable holder on the surface element in case of fire. Instead of the layer of intumescent material, the holder could also be pressed by means of springs or by gravity against the surface element, in the intumescent material, however, also assembly advantages and expansion takes place only in case of fire from a predetermined temperature.

umgreift der Halter das Flächenelement U-förmig mit Auslegern. Dadurch kann das Flächenelement in eine Richtung senkrecht zur Ebene des Flächenelementes durch die Ausleger gestützt werden. Die Ausleger können dabei formschlüssig oder mit Spiel an dem Flächenelement angeordnet sein.the holder surrounds the surface element U-shaped with arms. This allows the surface element in a direction perpendicular to the plane of the surface element be supported by the boom. The arms can be arranged positively or with play on the surface element.

Um den Halter geführt relativ zu dem Rahmen bewegen zu können, weist dieser vorzugsweise zwei Stege auf, die an dem Rahmen anliegen. Diese Stege können gegenüber der Ebene des Flächenelementes geneigt ausgebildet sein, sodass eine Vorfixierung mittels Klemmkräften möglich ist. Dabei kann mindestens ein Steg in eine Öffnung in dem Rahmen eingreifen, sodass ein besonders langer Führungsweg zwischen Halter und Rahmen möglich ist. Die an dem Halter ausgebildeten Stege können dabei elastisch sein und mit einer gewissen Vorspannung am Rahmen anliegen. Dies erleichtert die Montage, wenn der Halter an dem Rahmen vorfixiert wird und anschließend die Montage des Flächenelementes nicht behindert wird.To be able to move the holder guided relative to the frame, this preferably has two webs, which rest against the frame. These webs may be formed inclined relative to the plane of the surface element, so that a pre-fixing is possible by means of clamping forces. In this case, at least one web can engage in an opening in the frame, so that a particularly long guide path between the holder and the frame is possible. The webs formed on the holder can be elastic and rest with a certain bias on the frame. This facilitates the assembly when the holder is pre-fixed to the frame and then the assembly of the surface element is not hindered.

Für eine kostengünstige Herstellung des Halters ist dieser aus einem Stahlblech gestanzt und gebogen.For a cost-effective production of the holder this is punched and bent from a steel sheet.

In Figur 1 ist eine Brandschutztür im vertikalen Schnitt gezeigt, die einen Blendrahmen 1, einen relativ zu dem Blendrahmen 1 bewegbaren Rahmen 2 und eine Sprosse 3 aus wärmegedämmten Aluminiumprofilen aufweist. Die erfindungsgemäße Rahmenkonstruktion lässt sich nicht nur für einen Rahmen 2 einer Tür sondern auch allgemein für Blendrahmen oder Rahmen für Fassaden oder Lichtdächer etc. einsetzen. In dem gezeigten Ausführungsbeispiel ist der Rahmen 2 aus Aluminiumprofilen gebildet, die mittig über schlecht wärmeleitende Verbindungsleisten verbunden sind, wobei Material und Form des Rahmenprofils vom Fachmann frei gewählt werden kann.In FIG. 1 a fire door is shown in vertical section, which has a frame 1, a relative to the frame 1 movable frame 2 and a rung 3 of thermally insulated aluminum profiles. The frame construction according to the invention can be used not only for a frame 2 of a door but also generally for window frames or frames for facades or light roofs, etc. In the illustrated embodiment, the frame 2 is formed of aluminum profiles, which are connected in the middle of poorly heat-conducting connecting strips, wherein material and shape of the frame profile can be chosen freely by the skilled person.

In dem Rahmen 2 ist ein Flächenelement 10 in Form eines plattenförmigen Verglasungselementes 10 aufgenommen, wobei auch andere Flächenelemente 10 in dem Rahmen 2 gehalten sein können. Das Flächenelement 10 ist an dem Rahmen 2 in bekannter Weise über Glasanlagedichtungen 21 gehalten, die mit einem gewissen Anpressdruck am Rand umlaufend an dem Flächenelement 10 angeordnet sind.In the frame 2, a surface element 10 is received in the form of a plate-shaped glazing element 10, wherein also other surface elements 10 may be held in the frame 2. The surface element 10 is held on the frame 2 in a known manner via glass plant seals 21, which are arranged circumferentially on the surface element 10 with a certain contact pressure at the edge.

Zwischen dem Rahmen 2 und dem Flächenelement 10 sind Halter 4 vorgesehen, die aus einem Stahlblech gefertigt sind. Diese Halter 4 weisen Stege 5 auf, die in den Rahmen 2 eingreifen. Hierfür sind in dem Rahmen 2 Bohrungen 6 ausgespart, die zur Führung der Stege 5 dienen. Auf der gegenüberliegenden Seite weist der Halter 4 Ausleger 8 und 9 auf, die an einer Basisplatte 7 des Halters 4 angeformt sind. Die Ausleger 8 und 9 umgreifen das Flächenelement 10 mit geringfügigem Spiel.Between the frame 2 and the surface element 10 holders 4 are provided, which are made of a steel sheet. These holders 4 have webs 5, which engage in the frame 2. For this purpose, 2 holes 6 are recessed in the frame, which serve to guide the webs 5. On the opposite side, the holder has 4 arms 8 and 9, which are integrally formed on a base plate 7 of the holder 4. The boom 8 and 9 engage around the surface element 10 with slight play.

Unter der Basisplatte 7 des Halters 4 ist ein plattenförmiger Streifen 11 aus intumeszierendem Material angeordnet, der auf der gegenüberliegenden Seite am Profil des Rahmens 2 anliegt. Im Falle eines Brandes wird die Schwelltemperatur des intumeszierenden Streifen 11 überschritten und das Material schäumt auf und expandiert recht stark. Dadurch wird der benachbart angeordnete Halter 4 zu dem Flächenelement 10 gedrückt und liegt an diesem formschlüssig an. Dabei kann der Halter 4 eine Relativbewegung zum Flächenelement 10 hin ausführen und bleibt am Rahmen 2 durch die Stege 5 gehalten, die in den Öffnungen 6 geführt sind.Under the base plate 7 of the holder 4, a plate-shaped strip 11 of intumescent material is arranged, which bears against the profile of the frame 2 on the opposite side. In the case of a fire, the threshold temperature of the intumescent strip 11 is exceeded and the material foams up and expands quite strongly. As a result, the adjacently arranged holder 4 is pressed to the surface element 10 and abuts against it in a form-fitting manner. In this case, the holder 4 can perform a relative movement to the surface element 10 and remains held on the frame 2 by the webs 5, which are guided in the openings 6.

Sollten im Brandfall die Glasanlagedichtungen 21 ihre Funktion verlieren und das Flächenelement 10 sich aufgrund starker Hitzeentwicklung biegen, kann das Flächenelement 10 nach unten rutschen, wenn ein Verklotzungselement 20 seine Funktion verliert. Dann bleibt das Flächenelement 10 innerhalb der Ausleger 8 und 9 des oberen Halters 4, der dann gegen das Flächenelement 10 gedrückt wird und dafür sorgt, dass das Flächenelement 10 nicht aus dem Rahmen 2 herausfällt, auch wenn die obere Stirnkante des Flächenelementes 10 bereits den Rahmen 2 verlassen hat.Should the glass plant seals 21 lose their function in the event of a fire and the surface element 10 bends due to strong heat development, the surface element 10 can slide down when a blocking element 20 loses its function. Then, the surface element 10 remains within the arms 8 and 9 of the upper holder 4, which is then pressed against the surface element 10 and ensures that the surface element 10 does not fall out of the frame 2, even if the upper end edge of the surface element 10 already the frame 2 left.

In Figur 2 ist der Halter 4 dargestellt, der an gegenüberliegenden Seiten jeweils einen Steg 5 und zwei Ausleger 8 bzw. 9 aufweist. Die Halter 5 sind dabei in einem keilförmigen Winkel zueinander angeordnet, in diesem Fall von der Basisplatte 7 aus aufspreizend. In der Basisplatte 7 ist eine Aussparung 18 vorgesehen, die allerdings auch eine andere Geometrie haben kann. Ferner sind an dem Halter 4 Ausleger 8 und 9 vorgesehen, die auf der gegenüberliegenden Seite zu den Stegen 9 angeordnet sind und sich leicht verjüngen. Die Ausleger 8 und 9 sind dabei jeweils über dünne Stege 19 mit der Basisplatte 7 verbunden, wobei die Stege 19 über Ausstanzungen 12 voneinander beabstandet sind. Die Ausleger 8 und 9 können auch manuell umgebogen werden, wie dies beim Ausleger 8 mit dem in den gestrichelten Linien dargestellten Ausleger 8' gezeigt ist.In FIG. 2 the holder 4 is shown, which has on opposite sides in each case a web 5 and two arms 8 and 9, respectively. The holder 5 are arranged in a wedge-shaped angle to each other, in this case spread apart from the base plate 7. In the base plate 7, a recess 18 is provided, which, however, may also have a different geometry. Further, 4 arms 8 and 9 are provided on the holder, which are arranged on the opposite side to the webs 9 and taper slightly. The arms 8 and 9 are connected in each case via thin webs 19 with the base plate 7, wherein the webs 19 are spaced from each other via punched holes 12. The brackets 8 and 9 can also be bent manually, as shown in the boom 8 with the boom 8 'shown in the dashed lines.

In Figur 3 ist eine Explosionsdarstellung der einzelnen Bauteile der Rahmenkonstruktion gezeigt. Eine Profilwandung 13 des Rahmens 2 ist mit Öffnungen 6 versehen, die in einem Abstand a angeordnet sind und Öffnungen 6 mit dem Durchmesser c aufweisen. Benachbart zu der Profilwandung 13 ist ein Streifen 11 aus intumeszierendem Material angeordnet, der in etwa die Abmessungen der Basisplatte 7 des Halters 4 aufweist.In FIG. 3 an exploded view of the individual components of the frame construction is shown. A profile wall 13 of the frame 2 is provided with openings 6 which are arranged at a distance a and openings 6 having the diameter c. Adjacent to the profile wall 13, a strip 11 of intumescent material is arranged, which has approximately the dimensions of the base plate 7 of the holder 4.

Der Halter 4 weist eine Länge a auf, die in etwa dem Abstand der Öffnungen 6 entspricht. Die Stege 5 spreizen in einem Winkel α relativ zu einer Senkrechten zur Basisplatte 7 auf, der in einem Bereich von 5 bis 25° liegen kann, wobei die Elastizität der Stege 5 genutzt wird, damit diese unter einer gewissen Vorspannung an dem Rahmen 2 bzw. an einer Wand der Öffnung 6 anliegen. Die Stege 5 können statt nach außen aufzuspreizen auch nach innen zusammenlaufen.The holder 4 has a length a, which corresponds approximately to the spacing of the openings 6. The webs 5 spread at an angle α relative to a perpendicular to the base plate 7, which may be in a range of 5 to 25 °, the elasticity of the webs 5 is used so that they under a certain bias on the frame 2 and abut against a wall of the opening 6. The webs 5 can instead aufzuspreizen outward converge inwards.

In den Figuren 5 und 6 ist der Glashalter 4 noch einmal im Detail dargestellt. An der Basisplatte 7 sind auf einer Seite Ausleger 8 angeordnet, die für ein manuelles Verbiegen nur über Stege 19 mit der Basisplatte 7 verbunden sind, wobei an der Aussparung 12 Einkerbungen 14 und 17 sowie an der Außenkante eine Einkerbung 15 vorgesehen sind, damit ein leichtes Verbiegen des Auslegers 8 ermöglicht wird. Auch der Steg 5 ist durch einen Schlitz mit Kerbe 16 von dem Ausleger 8 getrennt, damit dieser in die gewünschte Richtung gebogen werden kann. Auf der gegenüberliegenden Seite der Basisplatte 7 ist der Halter 4 ohne Aussparungen 12 ausgebildet, wobei auch eine symmetrische Ausgestaltung möglich ist.In the FIGS. 5 and 6 the glass holder 4 is shown again in detail. On the base plate 7 are arranged on one side boom 8, which are connected for manual bending only via webs 19 with the base plate 7, wherein at the recess 12 notches 14 and 17 and at the outer edge of a notch 15 are provided so that a light Bending of the boom 8 is made possible. Also, the web 5 is separated by a slot with notch 16 of the boom 8 so that it can be bent in the desired direction. On the opposite side of the base plate 7, the holder 4 is formed without recesses 12, wherein a symmetrical configuration is possible.

Statt zwei Stegen 5, die in den Rahmen 2 eingreifen, können auch mehrere Stege 5 an dem Halter 4 angeordnet sein. Die Stege 5 können auch in entsprechende Nuten oder an Führungsflächen anliegen, um eine Überbrückung zwischen dem Rahmen 2 und dem Flächenelement 10 bereitzustellen, wenn aufgrund eines Brandes die übrigen Haltemittel nicht länger ihre Funktion erfüllen.Instead of two webs 5, which engage in the frame 2, a plurality of webs 5 may be arranged on the holder 4. The webs 5 can also rest in corresponding grooves or on guide surfaces in order to provide a bridging between the frame 2 and the surface element 10 when, due to a fire, the remaining holding means no longer fulfill their function.
