Description

Die Erfindung betrifft eine Brandschutz- und Entrauchungseinrichtung für Lüftungs- und Entrauchungsanlagen, umfassend zumindest ein in einem Gehäuse angeordnetes Absperrelement, wobei dieses Gehäuse in einen Lüftungs- oder Entrauchungskanal einsetzbar ist und wobei dem Absperrelement in seiner den Querschnitt des Gehäuses verschließenden Schließstellung Dichtungen zugeordnet sind.The invention relates to a fire protection and smoke extraction device for ventilation and smoke extraction systems comprising at least one arranged in a housing shut-off, said housing is insertable into a ventilation or smoke extraction and wherein the shut-off in its closing the cross-section of the housing closed position seals are assigned.

Brandschutzeinrichtungen mit Absperrelementen sind für den Brandfall bekannt. Sie verschließen einen Lüftungskanal, der beispielsweise durch eine Wand hindurchgeführt ist, um das Übertragen von Funken, Rauch und Hitze in einen angrenzenden Raum zu verhindern. Auch Entrauchungseinrichtungen mit Absperrelementen sind bekannt. Diese können im Normalfall geschlossen sein, bei einem Entrauchungsfall öffnen sie trotz Brandbelastung, um über Entrauchungskanäle oder -leitungen eine Entrauchung zu ermöglichen.Fire protection systems with shut-off elements are known for fire. They close a ventilation duct, which is passed through a wall, for example, to prevent the transmission of sparks, smoke and heat in an adjacent room. Also smoke extraction with shut-off elements are known. Normally, these can be closed; in the event of a smoke extraction, they open despite fire exposure in order to enable smoke extraction via smoke extraction ducts or ducts.

Die Erfindung betrifft eine kombinierte Brandschutz- und Entrauchungseinrichtung, deren Absperrelement einen Lüftungs- oder Entrauchungskanal gegen eine Übertragung des Brandes verschließt und deren Absperrelement zum Hindurchlassen von Rauch auch geöffnet werden kann. Nach den Normen kann eine derartige Brandschutz- und Entrauchungseinrichtung im Brandfall zu schließen sein und nach diesem Schließen für einen angenommenen Entrauchungsfall noch einmal zu öffnen sein. Die Dichtungen der Brandschutz- und Entrauchungseinrichtung müssen im Absperrfall einen dichten Verschluss der Lüftungs- oder Entrauchungsanlage gewährleisten, im Öffnungsfall bzw. Wiederöffnungsfall dürfen sie jedoch die Bewegung des Absperrelementes nicht behindern.The invention relates to a combined fire protection and smoke extraction device, the shutoff closes a ventilation or smoke extraction duct against transmission of fire and their shut-off for the passage of smoke can also be opened. According to the standards, such a fire protection and smoke extraction can be closed in case of fire and be opened again after this closing for an assumed smoke extraction. The seals of the fire protection and smoke extraction device must ensure a tight seal of the ventilation or smoke extraction system in the event of shutdown, in the event of shutdown Opening case or Wiederöffnungsfall but they must not hinder the movement of the shut-off.

Der Erfindung liegt die Aufgabe zugrunde, eine eingangs genannte Brandschutz- und Entrauchungseinrichtung aufzuzeigen, die verbessert sowohl eine dichte Absperrung im Brandfall als auch ein Öffnen und Wiederöffnen für das Ableiten von Rauch ermöglicht.The invention has for its object to provide a fire protection and smoke extraction device mentioned above, which improves both a tight barrier in case of fire and an opening and reopening for the discharge of smoke allows.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass jede Dichtung wenigstens einen Dichtungsabschnitt aus Intumeszenzmaterial hat, der in der Längsmittelebene des Absperrelementes in dessen Schließstellung angeordnet ist, und dem vorzugsweise in direkter Anlage beiderseitig jeweils ein Dichtungsabschnitt aus Nichtintumeszenzmaterial zugeordnet ist, wobei die Dichtungsabschnitte in Vertiefungen einer Wandung des Gehäuses angeordnet sind.This object is achieved according to the invention in that each seal has at least one sealing section made of intumescent material, which is arranged in the longitudinal center plane of the shut-off in its closed position, and preferably in direct contact on both sides each a sealing section of non-intumescent material is assigned, wherein the sealing portions in wells Wall of the housing are arranged.

Bei der erfindungsgemäßen Brandschutz- und Entrauchungseinrichtung wird für die Dichtung wenigstens ein Dichtungsabschnitt aus Intumeszenzmaterial eingesetzt. Ein derartiges Material dehnt sich bei höheren Temperaturen aus, es kann damit einen Zwischenraum zwischen Gehäusewand und Absperrelement vollständig ausfüllen und abdichten. Daher hat sich dieses Material bei Brandschutzeinrichtungen mit Absperrelementen bewährt.In the fire protection and smoke extraction device according to the invention, at least one sealing section of intumescent material is used for the seal. Such a material expands at higher temperatures, it can thus fill a gap between the housing wall and shut-off completely and seal. Therefore, this material has been proven in fire protection devices with shut-off.

Die erfindungsgemäße Brandschutzeinrichtung ist aber auch eine Entrauchungseinrichtung, so dass das Absperrelement auch für eine Rauchabführung im Brandfall zum Einhalten der entsprechenden insbesondere europäischen Normen zu öffnen ist. Das Intumeszenzmaterial darf dieses Öffnen nicht behindern. Dazu schlägt die Erfindung vor, dass das Intumeszenzmaterial vorübergehend oder für einen erforderlichen Zeitraum gegenüber einem Angriff von dessen Ausdehnung bewirkender Wärme vorzugsweise geschützt wird. In direkter Anlage sind beiderseitig des Dichtungsabschnittes aus Intumeszenzmaterial andere Dichtungsabschnitte aus Nichtintumeszenzmaterial vorgesehen, die insoweit das Intumeszenzmaterial gegen den Angriff von Wärme erst einmal schützen. Dies ist insbesondere dann gegeben, wenn sich das schwenkbare Absperrelement in seiner Schließstellung befindet. Dann ist es einem Abschnitt der Wandung des Gehäuses zugeordnet. In diesem Bereich sind zugleich die Dichtungen angeordnet. In der Längsmittelebene des Absperrelementes in dessen Schließstellung befindet sich der Dichtungsabschnitt aus Intumeszenzmaterial, flankierend zu jeder Längsseite dieses Dichtungsabschnitts sind die Dichtungsabschnitte aus Nichtintumeszenzmaterial angeordnet. Auf diese Weise ist der Dichtungsabschnitt aus Intumeszenzmaterial eingehaust, so dass einwirkende Wärme nicht unmittelbar auf dieses Intumeszenzmaterial treffen kann.However, the fire protection device according to the invention is also a smoke extraction device, so that the shut-off is also open for smoke removal in case of fire to comply with the relevant particular European standards. The intumescent material must not hinder this opening. For this purpose, the invention proposes that the intumescent material is preferably protected temporarily or for a required period of time against an attack of its expansion causing heat. In direct contact are on both sides of the sealing section of intumescent other sealing sections Non-intumescent material provided that protect the Intumeszenzmaterial against the attack of heat so far. This is especially true when the pivotable shut-off is in its closed position. Then it is associated with a portion of the wall of the housing. In this area, the seals are arranged at the same time. In the longitudinal center plane of the shut-off element in its closed position, the sealing section of intumescent material is located, flanking each longitudinal side of this sealing section, the sealing sections are arranged from nichtintumeszenzmaterial. In this way, the sealing portion of Intumeszenzmaterial is housed so that acting heat can not hit directly on this Intumeszenzmaterial.

Die erfindungsgemäße Brandschutz- und Entrauchungseinrichtung kann in dieser Weise ausschließlich aufgrund der Funktionalität der Dichtungsabschnitte aus Nichtintumeszenzmaterial Brandangriffen eine Zeit lang standhalten. Die Dichtungsabschnitte verändern sich nicht soweit, dass ein Öffnen oder Wiederöffnen des Absperrelementes verhindert ist. Für einen sich zeitlich später anschließenden Entrauchungsvorgang kann somit das Absperrelement noch immer geöffnet werden.The fire protection and smoke extraction device according to the invention can withstand fire attacks for a time in this manner solely due to the functionality of the sealing sections made of non-intumescent material. The sealing sections do not change so much that opening or reopening of the shut-off element is prevented. For a time later subsequent smoke extraction process thus the shut-off can still be opened.

Wird die erfindungsgemäße Brandschutz- und Entrauchungseinrichtung nicht für den Entrauchungsvorgang eingesetzt, wird und/oder bleibt sie geschlossen und wird daraufhin stärker mit Brand beaufschlagt. Dabei verlieren nach einem für ein mögliches Öffnen des Absperrelementes erforderlichen Zeitraum die Dichtungen aus Nichtintumeszenzmaterial aufgrund des Temperaturanstiegs allmählich an wärmeisolierender und abdichtender Wirkung. Damit mindert sich nach und nach der Schutz dieses Dichtungsabschnittes aus Nichtintumeszenzmaterial. Es wird vermehrt Wärme an das Intumeszenzmaterial übertragen, so dass dieses dann reagiert und sich ausdehnt. Dann erfolgt ein Festsetzen des Absperrelementes mit dem Intumeszenzmaterial und eine dichte und standhafte Brandschutzwirkung ist hergestellt.If the fire protection and smoke extraction device according to the invention is not used for the smoke extraction process, it will and / or will remain closed and then be subjected to more fire. In this case, after a period of time required for a possible opening of the shut-off element, the seals of non-intumescent material gradually lose their heat-insulating and sealing effect due to the temperature rise. This gradually reduces the protection of this sealing section of non-intumescent material. It is increasingly transferred heat to the intumescent, so that it then reacts and expands. Then a setting of the shut-off with the intumescent material and a dense and stable fire protection effect is produced.

Erfindungsgemäß ist vorgesehen, dass die Dichtungsabschnitte in Vertiefungen einer Wandung des Gehäuses angeordnet sind. Sowohl der Dichtungsabschnitt aus Intumeszenzmaterial als auch die Dichtungsabschnitte aus Nichtintumeszenzmaterial können in Vertiefungen angeordnet sein. Der freie Innenquerschnitt des Gehäuses wird dadurch erweitert, insbesondere wird die Schwenkbewegung des Absperrelementes nicht durch in den Schwenkweg vorstehende Abschnitte behindert.According to the invention it is provided that the sealing portions are arranged in recesses of a wall of the housing. Both the intumescent material sealing portion and the non-intumescent sealing portion may be disposed in recesses. The free inner cross-section of the housing is thereby extended, in particular, the pivoting movement of the shut-off element is not hindered by protruding into the pivoting sections.

Weiter kann vorgesehen sein, dass für den Dichtungsabschnitt aus Intumeszenzmaterial eine größere Vertiefung als zumindest eine Vertiefung für die Dichtungsabschnitte aus Nichtintumeszenzmaterial vorgesehen ist. Bei dieser Ausbildung ist der Dichtungsabschnitt aus Intumeszenzmaterial noch ein Stück weiter vom Innenquerschnitt des Gehäuses entfernt, wodurch seine Isolierung gegenüber einem Wärmeangriff verbessert sein kann. Oberhalb des Dichtungsabschnittes aus Intumeszenzmaterial bildet sich bei dieser Anordnung ein Hohlraum, der es gestattet, dass sich das Intumeszenzmaterial trotz der Abschirmung durch die Dichtungsabschnitte aus Nichtintumeszenzmaterial etwas ausdehnt, ohne die Bewegbarkeit des Absperrelementes zu behindern. Erst bei fortdauerndem Wärmeangriff dehnt sich das Intumeszenzmaterial soweit aus, dass es diesen Hohlraum überbrückt und sich an das Absperrelement anlegt.It can further be provided that a larger recess than at least one recess for the sealing sections of non-intumescent material is provided for the sealing section of intumescent material. In this embodiment, the sealing portion of intumescent material is further away from the inner cross section of the housing, whereby its isolation from heat attack can be improved. Above the sealing section made of intumescent material, in this arrangement, a cavity is formed, which allows the intumescent material to expand slightly despite the shielding through the sealing sections made of non-intumescent material, without hindering the movability of the blocking element. Only when the heat attack continues, the intumescent expands so far that it bridges this cavity and applies to the shut-off.

Nach einer anderen Weiterbildung der Erfindung kann vorgesehen sein, dass eine Dichtung aus Nichtintumeszenzmaterial in den Schwenkweg des Absperrelementes im Bereich dessen Schließstellung vorsteht. Diese vorstehende Dichtung kann einen Anschlag für das Absperrelement ausbilden. Da die vorstehende Dichtung im Bereich der Schließstellung des Absperrelementes in den Schwenkweg vorsteht, befindet sich das Absperrelement bei Anschlag an der vorstehenden Dichtung in seiner Schließstellung. Damit ist es der weiteren Dichtung aus Nichtintumeszenzmaterial sowie der Dichtung aus Intumeszenzmaterial zugeordnet.According to another embodiment of the invention can be provided that a seal of Nichtintumeszenzmaterial protrudes into the pivoting of the shut-off in the region of its closed position. This protruding seal can form a stop for the shut-off. Since the protruding seal projects in the region of the closed position of the shut-off in the pivoting path, the shut-off is at stop on the protruding seal in its closed position. Thus it is associated with the further seal of non-intumescent material and the seal of Intumeszenzmaterial.

Die vorgesehenen Dichtungsabschnitte können jeweils streifenförmig ausgebildet sein. Derartige Streifen können nebeneinander angeordnet werden, ein Streifen aus Intumeszenzmaterial wird beiderseitig von jeweils einem Streifen aus Nichtintumeszenzmaterial flankiert.The intended sealing portions may each be strip-shaped. Such strips can be arranged side by side, a strip of intumescent material is flanked on both sides by a strip of non-intumescent material.

Die Dichtungen aus Nichtintumeszenzmaterial können aus mineralischen Materialien, aus Glasseide oder aus Silikaten oder auch aus Kombinationen dieser Materialien ausgebildet sein.The non-intumescent material seals may be formed from mineral materials, glass silk or silicates, or combinations of these materials.
