Description

Die Erfindung betrifft eine Brandschutzvorrichtung für vorgehängte hinterlüftete Fassaden, mit einem Schließelement, das im Brandfall zum Verschließen eines Spalts in einer vorgehängten hinterlüfteten Fassade ausgelegt ist und das zwischen einer Offenstellung und einer Schließstellung verlagerbar ist, wobei ein Spannelement vorgesehen ist, welches das Schließelement in die Schließstellung beaufschlagt und zwischen einer Vorspannlage und einer Schließlage verlagerbar ist, wobei das Schließelement mittels eines Sicherungselements, in der Vorspannlage gehalten wird, wobei das Sicherungselement derart ausgelegt ist, dass es das Schließelement bei Überschreiten eines Temperaturgrenzwertes freigibt. Vorgehängte hinterlüftete Fassaden werden immer öfter dazu verwendet, um an Gebäuden, insbesondere an großen Bürogebäuden, eine ansprechende Außenfassade zu generieren. Dazu sind die vorgehängten hinterlüfteten Fassaden einer Gebäudewand derart vorgelagert, dass sich zwischen der Gebäudewand und der vorgehängten hinterlüfteten Fassade bzw. zwischen einer an der Gebäudewand angeordneten Wärmedämmschicht und der vorgehängten hinterlüfteten Fassade ein Spalt ausbildet. Dieser sogenannte Hinterlüftungsspalt kann sich oftmals über mehrere Stockwerke erstrecken. Im Brandfall besteht dabei die Möglichkeit, dass sich ein Brandherd über den Hinterlüftungsspalt von einem Stockwerk zu einem anderen Stockwerk ausbreitet. Um im Brandfall eine Flammenverlängerung und somit eine Ausbreitung des Feuers bei Eintritt einer Flamme in den Hinterlüftungsspalt zu verhindern, sind aus dem Stand der Technik Brandschutzvorrichtungen nach dem Oberbegriff des Anspruchs 1 bekannt.The invention relates to a fire protection device for curtain-type, rear-ventilated facades, with a closing element which, in the event of fire, is designed to close a gap in a curtain-type, rear-ventilated facade and which can be displaced between an open position and a closed position, a clamping element being provided which the closing element into the The closing position is acted upon and can be displaced between a pretensioning position and a closing position, the closing element being held in the pretensioning position by means of a securing element, the securing element being designed such that it releases the closing element when a temperature limit value is exceeded. Curtain-type, rear-ventilated facades are increasingly being used to generate an attractive exterior facade on buildings, especially on large office buildings. For this purpose, the curtain-type, rear-ventilated facades are positioned in front of a building wall in such a way that a gap is formed between the building wall and the curtain-type rear-ventilated facade or between a thermal insulation layer arranged on the building wall and the curtain-type rear-ventilated facade. This so-called rear ventilation gap can often extend over several floors. In the event of a fire, there is the possibility that the source of the fire could spread from one floor to another via the rear ventilation gap. In order to prevent the flame from extending in the event of a fire and thus from spreading of the fire when a flame enters the rear ventilation gap, fire protection devices according to the preamble of claim 1 are known from the prior art.

Die DE 20 2014 102 196 U1 zeigt eine solche Brandschutzvorrichtung nach dem Oberbegriff des Anspruchs 1. Das Schließelement ist in der DE 20 2014 102 196 U1 als Klappe ausgebildet, die an der Vorhangfassade angeordnet ist. Diese Klappe ist in einer Offenstellung entweder durch eine als Schnur ausgebildete Klappenbefestigung oder alternativ dazu durch ein zusätzliches Vorspannelement gesichert, wobei die Klappenbefestigung bei einer vorgegebenen Temperatur schmilzt, so dass die Klappe freigegeben wird.The DE 20 2014 102 196 U1 shows such a fire protection device according to the preamble of claim 1. The closing element is in the DE 20 2014 102 196 U1 designed as a flap which is arranged on the curtain wall. In an open position, this flap is secured either by a flap fastening designed as a cord or, alternatively, by an additional pretensioning element, the flap fastening melting at a predetermined temperature so that the flap is released.

Dabei hat es sich jetzt als nachteilig an der aus der DE 20 2014 102 196 U1 bekannten Vorrichtung herausgestellt, dass die Brandschutzvorrichtung einerseits nur auf komplizierte Weise an der Vorhangfassade befestigt werden kann und dass die Brandschutzvorrichtung aufgrund des Klappenaufbaus andererseits einen komplizierten Aufbau aufweist. Ferner ist es nicht möglich, die Brandschutzvorrichtung in eine an einer Gebäudewand angeordnete Wärmedämmschicht zu intergieren, so dass hieraus insgesamt ein größerer und komplizierterer Aufbau der gesamten Vorhangfassade resultiert.It has now proven to be detrimental to the out of the DE 20 2014 102 196 U1 known device found that the fire protection device on the one hand only on complicated Way can be attached to the curtain wall and that the fire protection device due to the flap structure on the other hand has a complicated structure. Furthermore, it is not possible to integrate the fire protection device into a thermal insulation layer arranged on a building wall, so that this results in a larger and more complicated structure of the entire curtain wall.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Brandschutzvorrichtung für vorgehängte hinterlüftete Fassaden bereitzustellen, die einerseits einfach zu montieren und in eine Wärmedämmschicht zu integrieren ist und andererseits einen einfachen Aufbau aufweist und kostengünstig herstellbar ist.The invention is therefore based on the object of providing a fire protection device for curtain-type, rear-ventilated facades which, on the one hand, is easy to assemble and can be integrated into a thermal insulation layer and, on the other hand, has a simple structure and is inexpensive to manufacture.

Diese Aufgabe wird durch eine Brandschutzvorrichtung für vorgehängte hinterlüftete Fassaden mit den Merkmalen des Anspruchs 1 gelöst. Eine derartige Brandschutzvorrichtung zeichnet sich dadurch aus, dass ein Befestigungselement vorgesehen ist, das zur Befestigung an einer Gebäudewand ausgelegt ist, und dass das Schließelement zur Befestigung eines Isolierungselements an der Gebäudewand ausgelegt ist, wobei das Befestigungselement und das Schließelement koaxial zu einer Mittellängsachse der Brandschutzvorrichtung angeordnet sind, wobei das Schließelement axial zwischen der Offenstellung und der Schließstellung verlagerbar ist. Mittels einer derartigen Brandschutzvorrichtung kann ein Isolierungselement, insbesondere ein brandhemmendes und/oder nicht brennbares Isolierungselement an einer Gebäudewand befestigt werden, wobei das Schließelement bei Überschreiten eines Temperaturgrenzwerts in die Schließstellung bewegt werden kann und so ein am Schließelement befestigtes brandhemmendes und/oder nicht brennbares Isolierungselement ebenfalls derart in die Schließstellung bewegt wird, dass ein sogenannter Hinterlüftungsspalt einer vorgehängten hinterlüfteten Fassade verschlossen werden kann. Besonders bevorzugt ist es dabei, wenn ein länglich ausgebildetes Isolierungselement auf einer vollen Breite einer Gebäudewand mittels einer Mehrzahl von Brandschutzvorrichtungen befestigt wird, so dass beim Verlagern der Brandschutzvorrichtungen in ihre jeweilige Schließstellung der Hinterlüftungsspalt auf der gesamten Breite der Gebäudewand verschlossen werden kann. Somit kann eine Brandschutzvorrichtung bereitgestellt werden, die einfach und kostengünstig herstellbar ist und die einfach zu montieren und in eine Wärmedämmschicht zu integrieren ist.This object is achieved by a fire protection device for curtain-type, rear-ventilated facades with the features of claim 1. Such a fire protection device is characterized in that a fastening element is provided which is designed for fastening to a building wall, and in that the closing element is designed for fastening an insulation element to the building wall, the fastening element and the closing element being arranged coaxially to a central longitudinal axis of the fire protection device are, wherein the closing element is axially displaceable between the open position and the closed position. By means of such a fire protection device, an insulation element, in particular a fire-retardant and / or non-combustible insulation element, can be attached to a building wall, the closing element being able to be moved into the closed position when a temperature limit is exceeded, and thus a closing element attached to the closing element fire-retardant and / or non-combustible insulation element is also moved into the closed position in such a way that a so-called rear ventilation gap of a curtain-type, rear-ventilated facade can be closed. It is particularly preferred if an elongated insulation element is attached to the full width of a building wall by means of a plurality of fire protection devices so that when the fire protection devices are moved into their respective closed position, the rear ventilation gap can be closed over the entire width of the building wall. In this way, a fire protection device can be provided which can be produced simply and inexpensively and which is easy to assemble and to integrate into a thermal insulation layer.

Als besonders vorteilhaft hat es sich dabei erwiesen, wenn das Spannelement das Schließelement in der Schließlage axial beaufschlagt. Wenn das Spannelement das Schließelement in seiner Schließlage axial beaufschlagt kann somit das Schließelement in seine Schließstellung bewegt werden, wenn das Sicherungselement bei Überschreiten eines Temperaturgrenzwerts, bspw. in einem Brandfall, das Schließelement freigibt.It has proven to be particularly advantageous if the tensioning element acts on the closing element axially in the closed position. When the clamping element acts on the closing element axially in its closed position, the closing element can thus be moved into its closed position when the securing element releases the closing element when a temperature limit value is exceeded, for example in the event of a fire.

Eine vorteilhafte Weiterbildung der Brandschutzvorrichtung sieht vor, dass das Schließelement das Befestigungselement radial zumindest abschnittsweise umgibt. Als besonders vorteilhaft hat es sich dabei erwiesen, wenn das Befestigungselement im Bereich, an dem das Schließelement am Befestigungselement angeordnet ist, kreiszylindrisch ausgebildet ist. Somit kann das Schließelement am Befestigungselement auf einfache Art und Weise axial beweglich geführt werden.An advantageous development of the fire protection device provides that the closing element surrounds the fastening element radially at least in sections. It has proven to be particularly advantageous if the fastening element is designed to be circular-cylindrical in the area in which the closing element is arranged on the fastening element. Thus, the closing element can be guided axially movably in a simple manner on the fastening element.

Gemäß einer weiteren Ausgestaltung der Brandschutzvorrichtung kann vorgesehen sein, dass das Sicherungselement als Zündschnur oder als Kunststoffschnur ausgebildet ist, die bei Überschreiten des Temperaturgrenzwertes aufschmilzt oder dass das Sicherungselement als flüssigkeitsbefüllte Glasampulle ausgebildet ist, die eine Luftblase enthält und bei Überschreiten des Temperaturgrenzwertes platzt, oder dass das Sicherungselement als Schmelzlot ausgebildet ist. Wenn das Sicherungselement als flüssigkeitsbefüllte Glasampulle ausgebildet ist kann aufgrund der Korrosionsbeständigkeit der Glasampulle eine besonders lange Funktionsfähigkeit der Brandschutzvorrichtung, auch von über 50 Jahren, gewährleistet werden.According to a further embodiment of the fire protection device, it can be provided that the fuse element is designed as a detonating cord or as a plastic cord that melts when the temperature limit value is exceeded or that the fuse element is designed as a liquid-filled glass ampoule that contains an air bubble and bursts when the temperature limit value is exceeded, or that the fuse element is designed as a fusible link. If the securing element is designed as a liquid-filled glass ampoule, a particularly long functionality of the fire protection device, even for over 50 years, can be guaranteed due to the corrosion resistance of the glass ampoule.

Vorteilhafterweise ist vorgesehen, dass das Schließelement einen helixförmigen Spiralbefestigungsabschnitt aufweist, der zum Einschrauben in ein brandhemmendes und/oder nicht brennbares Isolierungselement ausgelegt ist.It is advantageously provided that the closing element has a helical spiral fastening section which is designed to be screwed into a fire-retardant and / or non-combustible insulation element.

Besonders bevorzugt ist dabei, wenn der helixförmige Spiralbefestigungsabschnitt eine Helixsteigung aufweist, wobei am Befestigungselement ein Gewinde vorgesehen ist, das eine Gewindesteigung aufweist, die der Helixsteigung entspricht. Somit kann zunächst das brandhemmende und/oder nicht brennbare Isolierungselement an einer Gebäudewand angeordnet werden und dann die Brandschutzvorrichtung durch eine Drehbewegung gleichzeitig mittels des Befestigungselements einerseits mit der Gebäudewand verbunden werden und mittels des helixförmigen Spiralbefestigungsabschnitts andererseits in das brandhemmende und/oder nicht brennbare Isolierungselement eingebracht werden.It is particularly preferred if the helical spiral fastening section has a helical pitch, with a thread being provided on the fastening element which has a thread pitch that corresponds to the helical pitch. Thus, the fire-retardant and / or non-flammable insulation element can first be arranged on a building wall and then the fire-protection device can be connected to the building wall by means of a rotary movement at the same time by means of the fastening element on the one hand and introduced into the fire-retardant and / or non-flammable insulation element on the other hand using the helical spiral fastening section .

Eine weitere vorteilhafte Weiterbildung der Brandschutzvorrichtung sieht vor, dass das Befestigungselement einen Anschlag aufweist, wobei das Spannelement zwischen dem Anschlag und dem Schließelement angeordnet ist. Somit kann das Spannelement sich einerseits am Anschlag des Befestigungselements und andererseits am Schließelement abstützen und dieses axial in die Schließstellung beaufschlagen.Another advantageous development of the fire protection device provides that the fastening element has a stop, the tensioning element being arranged between the stop and the closing element. Thus, the clamping element can be supported on the one hand on the stop of the fastening element and on the other hand on the closing element and act on this axially in the closed position.

Um die Brandschutzvorrichtung einfach an einer Gebäudewand befestigen zu können hat es sich als vorteilhaft erwiesen, wenn das Befestigungselement einen Befestigungsabschnitt und einen Schaftabschnitt aufweist, wobei der Befestigungsabschnitt zur Anordnung in einer Gebäudewand ausgelegt ist. Der Befestigungsabschnitt kann dabei beispielsweise als in eine Gebäudewand einzementierbarer Anker, als Gewinde oder ähnliches ausgebildet sein. Besonders vorteilhaft ist es dabei, wenn das Befestigungselement im Bereich des Schaftabschnitts kreiszylindrisch ausgebildet ist.In order to be able to fasten the fire protection device simply to a building wall, it has proven to be advantageous if the fastening element has a fastening section and a shaft section, the fastening section being designed for arrangement in a building wall. The fastening section can be designed, for example, as an anchor that can be cemented into a building wall, as a thread or the like. It is particularly advantageous if the fastening element is designed to be circular-cylindrical in the region of the shaft section.

Um für das Spannelement eine möglichst große Anlagefläche bereitstellen zu können hat es sich ferner als vorteilhaft erwiesen, wenn der Anschlag als flanschartiger Ringbund ausgebildet ist, der zwischen dem Befestigungsabschnitt und dem Schaftabschnitt des Befestigungselements angeordnet ist.In order to be able to provide the largest possible contact surface for the tensioning element, it has also proven to be advantageous if the stop is designed as a flange-like annular collar which is arranged between the fastening section and the shaft section of the fastening element.

Besonders vorteilhaft ist es dabei, wenn der Anschlag als Schraubenmutter ausgebildet ist, wobei das Befestigungselement ein Außengewinde aufweist, wobei die Schraubenmutter auf das Außengewinde aufgeschraubt ist. Somit kann der Anschlag bzw. die Schraubenmutter besonders einfach und kostengünstig mit dem Befestigungselement verbunden werden.It is particularly advantageous if the stop is designed as a screw nut, the fastening element having an external thread, the screw nut being screwed onto the external thread. Thus, the stop or the nut can particularly can be easily and inexpensively connected to the fastener.

Um das Befestigungselement möglichst einfach an einer Gebäudewand zu montieren bzw. zu befestigen hat es sich als vorteilhaft erwiesen, wenn das Befestigungselement an seinem dem Befestigungsabschnitt abgewandten Ende am Schaftabschnitt einen Drehmomentantriebsabschnitt aufweist. Über diesen Drehmomentantriebsabschnitt kann dann bspw. mittels einer Schraub- oder Schlagwerkzeugs ein Antriebsdrehmoment in das Befestigungselement eingeleitet werden, so dass dieses in eine Rotation versetzt werden kann, wobei ein bspw. am Befestigungsabschnitt vorgesehenes Gewinde bspw. in einen in der Gebäudewand bspw. angeordneten Dübel und/oder Bohrloch eingeschraubt oder eingeschlagen werden kann.In order to mount or fasten the fastening element to a building wall as simply as possible, it has proven to be advantageous if the fastening element has a torque drive section on its end facing away from the fastening section on the shaft section. A drive torque can then be introduced into the fastening element via this torque drive section, for example by means of a screwing or impact tool, so that it can be set into rotation, with a thread provided on the fastening section, for example, in a dowel arranged in the building wall, for example and / or drilled hole can be screwed in or driven in.

Eine weitere besonders vorteilhafte Ausgestaltung der Brandschutzvorrichtung sieht vor, dass der Schaftabschnitt in Richtung der Mittellängsachse der Brandschutzvorrichtung eine Länge aufweist und dass das Schließelement in Richtung der Mittellängsachse der Brandschutzvorrichtung eine Länge aufweist, wobei die Länge des Schaftabschnitts größer ist als die Länge des Schließelements.Another particularly advantageous embodiment of the fire protection device provides that the shaft section has a length in the direction of the central longitudinal axis of the fire protection device and that the closing element has a length in the direction of the central longitudinal axis of the fire protection device, the length of the shaft section being greater than the length of the closing element.

Dabei ist es insbesondere möglich, dass der Schaftabschnitt das Schließelement axial überragt und im Bereich seines dem Befestigungsabschnitt abgewandten Endes eine Querbohrung aufweist, die zur Anordnung des Sicherungselements ausgelegt ist. Somit kann in der Querbohrung ein Sicherungselement derart angeordnet werden, dass das Schließelement in der Offenstellung gesichert werden kann, wobei beim Überschreiten eines Temperaturgrenzwertes das Sicherungselement bspw. aufschmilzt und das Schließelement entsprechend freigibt, so dass das Schließelement vom Spannelement in die Schließstellung verlagert wird. Dabei ist es denkbar, dass das Sicherungselement als Zündschnur oder als Kunststoffschnur ausgebildet ist, die bei einem entsprechenden Temperaturgrenzwert aufschmilzt.In this case, it is particularly possible for the shaft section to project axially beyond the closing element and, in the area of its end facing away from the fastening section, to have a transverse bore which is designed for the arrangement of the securing element. Thus, a securing element can be arranged in the transverse bore in such a way that the closing element can be secured in the open position, the securing element, for example, melting and the closing element when a temperature limit value is exceeded releases accordingly, so that the closing element is displaced from the clamping element into the closed position. It is conceivable that the securing element is designed as a detonating cord or as a plastic cord which melts at a corresponding temperature limit value.

Um ein an dem Schließelement befestigtes brandhemmendes und/oder nicht brennbares Isolierungselement einfach in die Schließstellung bewegen zu können, hat es sich als vorteilhaft erwiesen, wenn das Schließelement an einem ersten Ende eine scheibenartige Druckplatte aufweist und wenn das Schließelement an einem zweiten Ende eine Druckhülse aufweist, wobei die Druckhülse am zweiten Ende des Schließelements einen ersten zylindrischen Hülsenabschnitt aufweist und wobei zwischen dem ersten Ende und dem zweiten Ende des Schließelements ein zweiter Hülsenabschnitt vorgesehen ist, wobei sich das Schließelement im Bereich des zweiten Hülsenabschnitts radial aufweitet und wobei die Druckplatte mit der Druckhülse am ersten Ende im Bereich des zweiten Hülsenabschnitts verbunden ist. Die Druckplatte ist dabei vorteilhafterweise kreisförmig ausgebildet.In order to be able to easily move a fire-retardant and / or non-combustible insulation element attached to the closing element into the closed position, it has proven to be advantageous if the closing element has a disk-like pressure plate at a first end and if the closing element has a pressure sleeve at a second end , the pressure sleeve having a first cylindrical sleeve section at the second end of the closing element and a second sleeve section being provided between the first end and the second end of the closing element, the closing element expanding radially in the area of the second sleeve section and the pressure plate with the pressure sleeve is connected at the first end in the region of the second sleeve section. The pressure plate is advantageously circular.

Besonders vorteilhaft ist es dabei, wenn das Spannelement im Bereich des zweiten Hülsenabschnitts zumindest teilweise innerhalb der Druckhülse angeordnet ist. Somit kann das Spannelement vor äußeren Einflüssen wie bspw. vor dem Eindringen von Feuchtigkeit geschützt werden.It is particularly advantageous if the tensioning element is arranged at least partially within the pressure sleeve in the region of the second sleeve section. Thus, the tensioning element can be protected from external influences such as, for example, the penetration of moisture.

In einer kostengünstigen und zuverlässigen Weiterbildung der Brandschutzvorrichtung hat es sich dabei als vorteilhaft erwiesen, wenn das Spannelement als Schraubendruckfeder ausgebildet ist. Es ist jedoch auch denkbar, dass das Spannelement als Tellerfederpaket oder federndes Spannelement ausgebildet ist.In a cost-effective and reliable development of the fire protection device, it has proven to be advantageous if the tensioning element is designed as a helical compression spring. However, it is too It is conceivable that the clamping element is designed as a disk spring package or a resilient clamping element.

Die eingangs genannte Aufgabe wird ferner gelöst durch eine Brandschutzeinrichtung mit den Merkmalen des Anspruchs 17. Eine derartige Brandschutzeinrichtung umfasst wenigstens eine Brandschutzvorrichtung nach wenigstens einem der Ansprüche 1 bis 16 und wenigstens ein brandhemmendes und/oder nicht brennbares Isolierungselement.The above-mentioned object is also achieved by a fire protection device with the features of claim 17. Such a fire protection device comprises at least one fire protection device according to at least one of claims 1 to 16 and at least one fire-retardant and / or non-combustible insulation element.

Um das Sicherungselement außerhalb des brandhemmenden und/oder nicht brennbaren Isolierungselements anordnen zu können, ist es vorteilhaft, wenn die Druckhülse in Richtung der Mittellängsachse der Brandschutzvorrichtung eine Länge aufweist, die größer ist als eine Dicke des Isolierungselements. Somit überragt die Druckhülse ein Isolierungselement auch dann, wenn dieses an dem Schließelement befestigt ist.In order to be able to arrange the fuse element outside the fire-retardant and / or non-combustible insulation element, it is advantageous if the pressure sleeve has a length in the direction of the central longitudinal axis of the fire protection device which is greater than a thickness of the insulation element. Thus, the pressure sleeve protrudes beyond an insulation element even when it is attached to the closing element.

Vorteilhafterweise ist eine Mehrzahl von Brandschutzvorrichtungen vorgesehen, wobei die Brandschutzvorrichtungen ein gemeinsames Sicherungselement aufweisen. Somit können beim Überschreiten des Temperaturgrenzwertes alle Schießelemente der Brandschutzvorrichtungen gleichzeitig oder nahezu gleichzeitig in die Schließlage verlagert werden.A plurality of fire protection devices is advantageously provided, the fire protection devices having a common safety element. Thus, when the temperature limit value is exceeded, all the firing elements of the fire protection devices can be moved into the closed position at the same time or almost at the same time.

Die eingangs genannte Aufgabe wird darüber hinaus gelöst durch ein Brandschutzverfahren für vorgehängte hinterlüftete Fassaden mit den Merkmalen des Anspruchs 20. Ein derartiges Verfahren umfasst die folgenden Schritte: horizontales Anordnen wenigstens eines brandhemmenden und/oder nicht brennbaren Isolierungselements mittels einer Brandschutzvorrichtung nach wenigstens einem der Ansprüche 1 bis 16. Vorteilhafterweise werden die Isolierungselemente mit den jeweiligen Brandschutzvorrichtungen auf einer horizontalen Linie angeordnet, so dass ein Hinterlüftungsspalt auf einer gesamten Breite einer Gebäudewand im Brandfall verschlossen werden kann.The above-mentioned object is also achieved by a fire protection method for curtain-type, rear-ventilated facades with the features of claim 20. Such a method comprises the following steps: horizontal arrangement of at least one fire-retardant and / or non-combustible insulation element by means of a fire protection device according to at least one of the claims 1 to 16. The insulation elements with the respective fire protection devices are advantageously arranged on a horizontal line so that a ventilation gap can be closed over the entire width of a building wall in the event of a fire.

Es hat sich für eine einfache Montage als besonders vorteilhaft erwiesen, wenn zunächst dieIt has proven to be particularly advantageous for simple assembly if the first

Brandschutzvorrichtung an der Gebäudewand und danach das brandhemmende und/oder nicht brennbare Isolierungselement angebracht wird.Fire protection device is attached to the building wall and then the fire-retardant and / or non-flammable insulation element.

In den Figuren 1 und 2 ist insgesamt eine erfindungsgemäße Brandschutzvorrichtung 10 gezeigt, wobei die Brandschutzvorrichtung 10 in Figur 1 in einer Offenstellung dargestellt ist. Figur 2 zeigt die Brandschutzvorrichtung 10 gemäß Figur 1 im Schnitt entlang der Linie A-A.In the Figures 1 and 2 a fire protection device 10 according to the invention is shown overall, the fire protection device 10 in FIG Figure 1 is shown in an open position. Figure 2 shows the fire protection device 10 according to FIG Figure 1 in section along the line AA.

In den Figuren 3 und 4 ist die Brandschutzvorrichtung 10 als Teil einer Brandschutzeinrichtung 12 gezeigt, wobei die Brandschutzvorrichtung 10 in Figur 3 in der Offenstellung und in Figur 4 in einer Schließstellung dargestellt ist.In the Figures 3 and 4th the fire protection device 10 is shown as part of a fire protection device 12, the fire protection device 10 in FIG Figure 3 in the open position and in Figure 4 is shown in a closed position.

Die Brandschutzvorrichtung 10 ist als Brandschutzvorrichtung 10 für vorgehängte hinterlüftete Fassaden 13 ausgelegt und weist ein Schließelement 14 auf, das im Brandfall zum Verschließen eines in den Figuren 3 und 4 gezeigten Spalts 16 in einer vorgehängten hinterlüfteten Fassade ausgelegt ist und das zwischen einer Offenstellung und einer Schließstellung verlagerbar ist. Das Schließelement 14 ist zur Befestigung eines Isolierungselements 18 an einer Gebäudewand 20 (vgl. Fig. 3 und 4) ausgelegt.The fire protection device 10 is designed as a fire protection device 10 for curtain-type, rear-ventilated facades 13 and has a closing element 14 which, in the event of a fire, is used to close one in the Figures 3 and 4th The gap 16 shown is designed in a curtain-type, rear-ventilated facade and which can be displaced between an open position and a closed position. The closing element 14 is for fastening an insulation element 18 to a building wall 20 (cf. Fig. 3 and 4th ) designed.

Die Brandschutzvorrichtung 10 weist ferner ein Befestigungselement 22 auf, das zur Befestigung an einer Gebäudewand 20 (vgl. Fig. 3 und 4) ausgelegt ist. Das Befestigungselement 22 und das Schließelement 14 sind koaxial zu einer Mittellängsachse 24 der Brandschutzvorrichtung 10 angeordnet, wobei das Schließelement 14 axial, d.h. in Richtung der Mittellängsachse 24 zwischen der Offenstellung und der Schließstellung verlagerbar ist.The fire protection device 10 also has a fastening element 22 which is used for fastening to a building wall 20 (cf. Fig. 3 and 4th ) is designed. The fastening element 22 and the closing element 14 are arranged coaxially to a central longitudinal axis 24 of the fire protection device 10, the closing element 14 being displaceable axially, ie in the direction of the central longitudinal axis 24 between the open position and the closed position.

Das Schließelement 14 umgibt das Befestigungselement 22 radial (d.h. senkrecht zur Mittellängsachse 24) zumindest abschnittsweise. Das Befestigungselement 22 weist einen Befestigungsabschnitt 26 und einen Schaftabschnitt 28 auf, wobei der Befestigungsabschnitt 26 zur Anordnung in einer Gebäudewand 20 (vgl. Fig. 3 und 4) ausgelegt ist. Der Befestigungsabschnitt 26 kann dabei beispielsweise als in eine Gebäudewand 20 einzementierbarer Anker, als Gewinde oder ähnliches ausgebildet sein. Dabei ist das Befestigungselement 22 im Bereich, an dem das Schließelement 14 am Befestigungselement 22 angeordnet ist, d.h. am Schaftabschnitt 28, kreiszylindrisch ausgebildet. Somit kann das Schließelement 14 am Befestigungselement 22 bzw. am Schaftabschnitt 28 auf einfache Art und Weise axial beweglich geführt werden.The closing element 14 surrounds the fastening element 22 radially (ie perpendicular to the central longitudinal axis 24) at least in sections. The fastening element 22 has a fastening section 26 and a shaft section 28, the fastening section 26 for arrangement in a building wall 20 (cf. Fig. 3 and 4th ) is designed. The fastening section 26 can be designed, for example, as an anchor that can be cemented into a building wall 20, as a thread or the like. In this case, the fastening element 22 in the area in which the closing element 14 is arranged on the fastening element 22, ie on the shaft section 28, is designed to be circular-cylindrical. Thus, the closing element 14 can be guided axially movably in a simple manner on the fastening element 22 or on the shaft section 28.

Das Befestigungselement 22 weist einen Anschlag 30, der als flanschartiger Ringbund ausgebildet ist und zwischen dem Befestigungsabschnitt 26 und dem Schaftabschnitt 28 des Befestigungselements 22 angeordnet ist. Im vorliegenden Fall ist der Anschlag 30 als Schraubenmutter 32 ausgebildet, wobei das Befestigungselement 22 ein in den Figuren nicht gezeigtes Außengewinde aufweist, wobei die Schraubenmutter 32 auf das Außengewinde aufgeschraubt ist. Somit kann der Anschlag 30 bzw. die Schraubenmutter 32 besonders einfach und kostengünstig mit dem Befestigungselement 22 verbunden werden.The fastening element 22 has a stop 30, which is designed as a flange-like annular collar and is arranged between the fastening section 26 and the shaft section 28 of the fastening element 22. In the present case, the stop 30 is designed as a screw nut 32, the fastening element 22 having an external thread (not shown in the figures), the screw nut 32 being screwed onto the external thread. The stop 30 or the screw nut 32 can thus be connected to the fastening element 22 in a particularly simple and cost-effective manner.

Um das Befestigungselement 22 möglichst einfach an einer Gebäudewand 20 zu montieren bzw. zu befestigen, weist das Befestigungselement 22 an seinem dem Befestigungsabschnitt 26 abgewandten Ende am Schaftabschnitt 28 einen Drehmomentantriebsabschnitt 34 auf. Über diesen Drehmomentantriebsabschnitt 34 kann dann bspw. mittels einer Bohrmaschine oder eines Akkuschraubers ein Antriebsdrehmoment in das Befestigungselement 22 eingeleitet werden, so dass dieses in eine Rotation versetzt werden kann, wobei ein am Befestigungsabschnitt 26 vorgesehenes Gewinde bspw. in einen in der Gebäudewand 20 angeordneten Dübel zur Befestigung des Befestigungselements 22 in der Gebäudewand 20 eingeschraubt werden kann.In order to mount or fasten the fastening element 22 to a building wall 20 as simply as possible, the fastening element 22 has a torque drive section 34 on its end facing away from the fastening section 26 on the shaft section 28. A drive torque can then be applied to the fastening element 22 via this torque drive section 34, for example by means of a drill or a cordless screwdriver can be introduced so that it can be set in rotation, a thread provided on the fastening section 26, for example, being screwed into a dowel arranged in the building wall 20 for fastening the fastening element 22 in the building wall 20.

Das Schließelement 14 weist an einem ersten Ende 36 eine scheibenartige Druckplatte 38 auf. Ferner weist das Schließelement 14 an einem zweiten Ende 40 eine Druckhülse 42 auf. Die Druckhülse 42 weist am zweiten Ende 40 des Schließelements 14 einen ersten zylindrischen, insbesondere kreiszylindrischen Hülsenabschnitt 44 auf. Darüber hinaus weist die Druckhülse 42 zwischen dem ersten Ende 36 und dem zweiten Ende 40 des Schließelements 14 einen zweiten Hülsenabschnitt 46 auf, wobei sich das Schließelement 14 im Bereich des zweiten Hülsenabschnitts 46 radial, d.h. senkrecht zur Mittellängsachse 24 aufweitet. Die Druckplatte 38 ist mit der Druckhülse 42 am ersten Ende 36 im Bereich des zweiten Hülsenabschnitts 46 verbunden. Die Druckplatte 38 ist dabei kreisförmig ausgebildet und weist einen Durchmesser im Bereich von etwa 20mm bis etwa 100mm auf.The closing element 14 has a disk-like pressure plate 38 at a first end 36. Furthermore, the closing element 14 has a pressure sleeve 42 at a second end 40. The pressure sleeve 42 has a first cylindrical, in particular circular cylindrical, sleeve section 44 at the second end 40 of the closing element 14. In addition, the pressure sleeve 42 has a second sleeve section 46 between the first end 36 and the second end 40 of the closing element 14, the closing element 14 expanding radially in the region of the second sleeve section 46, i.e. perpendicular to the central longitudinal axis 24. The pressure plate 38 is connected to the pressure sleeve 42 at the first end 36 in the area of the second sleeve section 46. The pressure plate 38 is circular and has a diameter in the range from approximately 20 mm to approximately 100 mm.

Die Brandschutzvorrichtung 10 weist ferner ein als Schraubendruckfeder ausgebildetes Spannelement 48 auf, welches das Schließelement 14 in die Schließstellung beaufschlagt und zwischen einer Vorspannlage und einer Schließlage verlagerbar ist, wobei das Schließelement 48 mittels eines Sicherungselements 50 in der Vorspannlage gehalten wird, wobei das Sicherungselement 50 derart ausgelegt ist, dass es das Schließelement 14 bei Überschreiten eines Temperaturgrenzwertes freigibt. Das Spannelement 48 beaufschlagt das Schließelement 14 in der Schließlage axial. Hierzu ist das Spannelement 48 zwischen dem Anschlag 30 bzw. der Schraubenmutter 32 und dem Schließelement 14 angeordnet. Somit kann das Spannelement 48 sich einerseits am Anschlag 30 des Befestigungselements 22 und andererseits am Schließelement 14 abstützen und dieses axial in die Schließstellung beaufschlagen.The fire protection device 10 also has a tensioning element 48, designed as a helical compression spring, which urges the closing element 14 into the closed position and can be displaced between a pretensioned position and a closed position, the closing element 48 being held in the pretensioned position by means of a securing element 50, the securing element 50 in this way is designed so that it releases the closing element 14 when a temperature limit value is exceeded. The tensioning element 48 acts on the closing element 14 axially in the closed position. For this purpose, the clamping element 48 is between the stop 30 or the screw nut 32 and the closing element 14 are arranged. Thus, the clamping element 48 can be supported on the one hand on the stop 30 of the fastening element 22 and on the other hand on the closing element 14 and act on this axially in the closed position.

Das Spannelement 48 ist im Bereich des zweiten Hülsenabschnitts 46 zumindest teilweise innerhalb der Druckhülse 42 angeordnet. Somit kann das Spannelement 48 vor äußeren Einflüssen wie bspw. vor dem Eindringen von Feuchtigkeit geschützt werden.The tensioning element 48 is arranged at least partially within the pressure sleeve 42 in the region of the second sleeve section 46. The tensioning element 48 can thus be protected from external influences such as, for example, from the penetration of moisture.

Der Schaftabschnitt 28 weist in Richtung der Mittellängsachse 24 der Brandschutzvorrichtung 10 eine Länge 52 auf, wobei das Schließelement 14 in Richtung der Mittellängsachse 24 der Brandschutzvorrichtung 10 eine Länge 54 aufweist. Die Länge 52 des Schaftabschnitts 28 ist dabei größer als die Länge 54 des Schließelements 14, so dass der Schaftabschnitt 28 bei am Schaftabschnitt 28 angeordneten Schließelement 14 das Schließelement 14 axial überragt. Der Schaftabschnitt 28 weist dabei im Bereich seines dem Befestigungsabschnitt 26 abgewandten Endes eine Querbohrung 56 auf, die zur Anordnung des Sicherungselements 50 ausgelegt ist. Somit kann in der Querbohrung 56 ein Sicherungselement 50 derart angeordnet werden, dass das Schließelement 14 in der Offenstellung gesichert werden kann, wobei beim Überschreiten eines Temperaturgrenzwertes das Sicherungselement 50 bspw. aufschmilzt und das Schließelement 14 entsprechend freigibt, so dass das Schließelement 14 vom Spannelement 48 in die Schließstellung verlagert wird. Dabei ist es denkbar, dass das Sicherungselement 50 als Zündschnur oder als Kunststoffschnur ausgebildet ist, die bei einem entsprechenden Temperaturgrenzwert aufschmilzt.The shaft section 28 has a length 52 in the direction of the central longitudinal axis 24 of the fire protection device 10, the closing element 14 having a length 54 in the direction of the central longitudinal axis 24 of the fire protection device 10. The length 52 of the shank section 28 is greater than the length 54 of the closing element 14, so that the shank section 28 projects axially beyond the closing element 14 when the closing element 14 is arranged on the shank section 28. The shaft section 28 has a transverse bore 56 in the area of its end facing away from the fastening section 26, which is designed for the arrangement of the securing element 50. Thus, a securing element 50 can be arranged in the transverse bore 56 in such a way that the closing element 14 can be secured in the open position, the securing element 50 melting, for example, and releasing the closing element 14 accordingly when a temperature limit value is exceeded, so that the closing element 14 is released from the clamping element 48 is shifted into the closed position. It is conceivable that the securing element 50 is designed as a detonating cord or as a plastic cord which melts at a corresponding temperature limit value.

Die in den Figuren 3 und 4 gezeigte Brandschutzeinrichtung 14 umfasst wenigstens eine Brandschutzvorrichtung 10 sowie wenigstens ein brandhemmendes und/oder nicht brennbares Isolierungselement 18. An der Gebäudewand 20 ist eine Wärmedämmschicht 58 angeordnet, wobei zwischen der Wärmedämmschicht 58 ein länglich ausgebildetes brandhemmendes und/oder nicht brennbares Isolierungselement 18 mittels einer Mehrzahl von Brandschutzvorrichtungen 10 befestigt ist.The ones in the Figures 3 and 4th The fire protection device 14 shown comprises at least one fire protection device 10 as well as at least one fire-retardant and / or non-combustible insulation element 18. A thermal insulation layer 58 is arranged on the building wall 20, with an elongated fire-retardant and / or non-combustible insulation element 18 between the thermal insulation layer 58 by means of a plurality of Fire protection devices 10 is attached.

Dabei weist die Druckhülse 42 in Richtung der Mittellängsachse 24 der Brandschutzvorrichtung 10 eine Länge 60 auf, die größer ist als eine Dicke 62 des Isolierungselements 18 bzw. der Wärmedämmschicht 58. Somit überragt die Druckhülse 42 das Isolierungselement 18 auch dann, wenn dieses am Schließelement 14 der Brandschutzvorrichtung 10 befestigt ist. Somit kann das Sicherungselement 50 außerhalb des brandhemmenden und/oder nicht brennbaren Isolierungselements 18 angeordnet werden.The pressure sleeve 42 has a length 60 in the direction of the central longitudinal axis 24 of the fire protection device 10, which is greater than a thickness 62 of the insulation element 18 or the thermal insulation layer 58 the fire protection device 10 is attached. The fuse element 50 can thus be arranged outside the fire-retardant and / or non-combustible insulation element 18.

Bei Überschreiten eines Temperaturgrenzwerts kann dann das Sicherungselement 50 bspw. aufgeschmolzen werden, so dass das Schließelement 14 vom Spannelement 48 in die Schließstellung bewegt wird und so das am Schließelement 14 befestigte brandhemmende und/oder nicht brennbare Isolierungselement 18 ebenfalls derart in die Schließstellung bewegt wird, dass ein sogenannter Hinterlüftungsspalt 16 einer vorgehängten hinterlüfteten Fassade 13 verschlossen werden kann. Somit kann durch das längliche brandhemmende und/oder nicht brennbare Isolierungselement 18 der Hinterlüftungsspalt 16 auf einer gesamten Breite der Gebäudewand 20 verschlossen werden kann.If a temperature limit value is exceeded, the securing element 50 can then be melted, for example, so that the closing element 14 is moved into the closed position by the clamping element 48 and the fire-retardant and / or non-combustible insulation element 18 attached to the closing element 14 is also moved into the closed position in such a way that that a so-called rear ventilation gap 16 of a curtain-type rear-ventilated facade 13 can be closed. Thus, through the elongated fire-retardant and / or non-combustible insulation element 18, the ventilation gap 16 can be closed over an entire width of the building wall 20.

Im Brandfall kann daher verhindert werden, dass sich ein Brandherd über den Hinterlüftungsspalt 16 von einem Stockwerk eines Gebäudes zu einem anderen Stockwerk des Gebäudes ausbreitet.In the event of a fire, a source of fire can therefore be prevented from spreading via the rear ventilation gap 16 from one floor of a building to another floor of the building.

Somit kann eine Brandschutzvorrichtung 10 bereitgestellt werden, die einfach und kostengünstig herstellbar ist und die einfach zu montieren und in eine Wärmedämmschicht 58 zu integrieren ist.In this way, a fire protection device 10 can be provided which can be produced simply and inexpensively and which is easy to assemble and to integrate into a thermal insulation layer 58.
