Description

Die Erfindung betrifft eine Brandschutz- und Entrauchungseinrichtung für Lüftungs- und Entrauchungsanlagen, umfassend zumindest ein schwenkbar 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, die jeweils wenigstens einen Dichtungsabschnitt aus Intumeszenzmaterial haben, der in der Längsmittelebene des Absperrelementes in dessen Schließstellung angeordnet ist.The invention relates to a fire protection and smoke extraction device for ventilation and smoke extraction systems, comprising at least one shut-off element pivotably arranged in a housing, this housing being insertable into a ventilation or smoke extraction duct and seals being assigned to the shut-off element in its closed position which closes the cross section of the housing , each of which has at least one sealing section made of intumescent material, which is arranged in the longitudinal center plane of the shut-off element in its closed position.

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.Fire protection systems with shut-off elements are known in the event of a fire. They close a ventilation duct that runs through a wall, for example, to prevent sparks, smoke and heat from being transferred to an adjacent room. Smoke extraction devices with shut-off elements are also known.

Diese können im Normalfall geschlossen sein, bei einem Entrauchungsfall öffnen sie trotz Brandbelastung, um über Entrauchungskanäle oder -leitungen eine Entrauchung zu ermöglichen.These can normally be closed, but in the event of a smoke extraction they open despite fire exposure to enable smoke extraction via smoke extraction ducts or pipes.

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 shut-off element of which closes a ventilation or smoke extraction duct against the spread of fire and the shut-off element of which can also be opened to allow smoke to pass through. According to the standards, such a fire protection and smoke extraction device can have to be closed in the event of a fire and, after this closure, can be opened again for an assumed smoke extraction event. The seals of the fire protection and smoke extraction system must ensure a tight closure of the ventilation or smoke extraction system when it is shut off; however, when it is opened or reopened, they must not hinder the movement of the shut-off element.

Eine Brandschutzeinrichtung nach dem Oberbegriff des Anspruchs 1 ist in der DE 103 50 872 A1 gezeigt. Dort sind für das Klappenblatt einseitige Anschläge zur Begrenzung seiner Schwenkbewegung vorgesehen. Eine Brandschutzklappe ist auch noch aus der EP 0 512 414 A2 bekannt.A fire protection device according to the preamble of claim 1 is in the DE 103 50 872 A1 shown. One-sided stops are provided there for the flap leaf to limit its pivoting movement. A fire damper is also still available EP 0 512 414 A2 known.

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 is based on the object of showing a fire protection and smoke extraction device mentioned at the beginning, which improves both a tight barrier in the event of a fire and enables opening and reopening to dissipate smoke.

Diese Aufgabe ist erfindungsgemäß durch eine Brandschutz- und Entrauchungseinrichtung nach Anspruch 1 gelöst, bei der dem Dichtungsabschnitt aus Intumeszenzmaterial beiderseitig jeweils ein Dichtungsabschnitt aus Nichtintumeszenzmaterial zugeordnet ist, wobei die Dichtungsabschnitte in Vertiefungen einer Wandung des Gehäuses angeordnet sind und die Dichtungsabschnitte aus Nichtintumeszenzmaterial den Dichtungsabschnitt aus Intumeszenzmaterial jeweils so einhausen, dass einwirkende Wärme nicht unmittelbar auf das Intumeszenzmaterial wirken kann.This object is achieved according to the invention by a fire protection and smoke extraction device according to claim 1, in which the sealing section made of intumescent material is assigned a sealing section made of non-intumescent material on both sides, the sealing sections being arranged in recesses in a wall of the housing and the sealing sections made of non-intumescent material the sealing section made of intumescent material Enclose each in such a way that heat cannot directly affect the intumescent material.

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 made of intumescent material is used for the seal. Such a material expands at higher temperatures and can therefore completely fill and seal a gap between the housing wall and the shut-off element. This material has therefore proven itself in fire protection systems with shut-off elements.

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.The fire protection device according to the invention is also a smoke extraction device, so that the shut-off element can also be opened to remove smoke in the event of a fire in order to comply with the corresponding, particularly European, standards. The intumescent material must not hinder this opening. For this purpose, the invention proposes that the intumescent material be temporarily or for a required period of time protected from attack by heat causing its expansion is preferably protected. In direct contact, other sealing sections made of non-intumescent material are provided on both sides of the sealing section made of intumescent material, which initially protect the intumescent material against the attack of heat. This is particularly the case when the pivotable shut-off element is in its closed position. It is then assigned to a section of the wall of the housing. The seals are also arranged in this area. The sealing section made of intumescent material is located in the longitudinal center plane of the shut-off element in its closed position; the sealing sections made of non-intumescent material are arranged flanking each longitudinal side of this sealing section. In this way, the sealing section is encased in intumescent material, so that heat acting cannot directly impact this intumescent material.

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.In this way, the fire protection and smoke extraction device according to the invention can withstand fire attacks for a period of time solely due to the functionality of the sealing sections made of non-intumescent material. The sealing sections do not change to such an extent that the shut-off element cannot be opened or reopened. The shut-off element can therefore still be opened for a later smoke extraction process.

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 is and/or remains closed and is then exposed to more fire. After a period of time required for the shut-off element to be opened, the seals made of non-intumescent material gradually lose their heat-insulating and sealing effect due to the increase in temperature. This gradually reduces the protection of this sealing section made of non-intumescent material. Increased heat is transferred to the intumescent material, so that it then reacts and expands. Then The shut-off element is fixed with the intumescent material and a tight and stable fire protection effect is created.

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 sections are arranged in recesses in a wall of the housing. Both the sealing section made of intumescent material and the sealing sections made of non-intumescent material can be arranged in depressions. The free internal cross section of the housing is thereby expanded; in particular, the pivoting movement of the shut-off element is not hindered by sections protruding into the pivoting path.

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.Furthermore, it can be provided that a larger depression is provided for the sealing section made of intumescent material than at least one depression for the sealing sections made of non-intumescent material. In this design, the sealing section made of intumescent material is a little further away from the inner cross section of the housing, which can improve its insulation against heat attack. In this arrangement, a cavity is formed above the sealing section made of intumescent material, which allows the intumescent material to expand somewhat despite the shielding by the sealing sections made of non-intumescent material without hindering the mobility of the shut-off element. Only when the heat attack continues does the intumescent material expand to such an extent that it bridges this cavity and rests against the shut-off element.

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 development of the invention, it can be provided that a seal made of non-intumescent material protrudes into the pivoting path of the shut-off element in the area of its closed position. This protruding seal can form a stop for the shut-off element. Since the protruding seal protrudes into the pivoting path in the area of the closed position of the shut-off element, the shut-off element is in its closed position when it stops against the protruding seal. That's it for the rest Seal made of non-intumescent material and assigned to the seal made of intumescent material.

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 sealing sections provided can each be designed in the form of strips. Such strips can be arranged next to each other; a strip made of intumescent material is flanked on both sides by a strip made 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 seals made of non-intumescent material can be made of mineral materials, glass fiber or silicates or even combinations of these materials.

Die Brandschutz- und Entrauchungseinrichtung nach jedem der beiden Ausführungsbeispiele hat ein quaderförmiges Gehäuse 1, in das ein Absperrelement 2 schwenkbar eingesetzt ist. Das Gehäuse 1 ist auf seiner Außenseite mit einem umlaufenden Rahmen 3 belegt, der auf die Wandungen 4 des Gehäuses 1 aufgelegt ist.The fire protection and smoke extraction device according to each of the two exemplary embodiments has a cuboid housing 1 into which a shut-off element 2 is pivotally inserted. The outside of the housing 1 is covered with a surrounding frame 3, which is placed on the walls 4 of the housing 1.

Die Schnittansichten in Figur 4 und in Figur 9 zeigen in der jeweils geöffneten Stellung des Absperrelementes 2 auf der Innenseite einer Gehäusewandung 4 streifenförmige Dichtungsabschnitte. Es handelt sich jeweils um drei Dichtungsabschnitte, die im Einzelnen in den vergrößerten Darstellungen Figur 5 und Figur 10 erläutert sind.The sectional views in Figure 4 and in Figure 9 show 4 strip-shaped sealing sections on the inside of a housing wall in the open position of the shut-off element 2. There are three sealing sections in each case, which are shown in detail in the enlarged illustrations Figure 5 and Figure 10 are explained.

In Figur 5 ist die Längsmittelebene des Absperrelementes 2 durch eine gestrichelte Linie 5 verdeutlicht. In dieser Längsmittelebene ist ein erster Dichtungsabschnitt 8 aus Intumeszenzmaterial angeordnet. Dieser Dichtungsabschnitt 8 aus Intumeszenzmaterial ist eingefasst auf jeder seiner Längsseiten durch einen Dichtungsabschnitt 7 aus Nichtintumeszenzmaterial.In Figure 5 the longitudinal center plane of the shut-off element 2 is illustrated by a dashed line 5. A first sealing section 8 made of intumescent material is arranged in this longitudinal center plane. This seal section 8 made of intumescent material is enclosed on each of its long sides by a sealing section 7 made of non-intumescent material.

Bei dem ersten Ausführungsbeispiel nach Figuren 1 bis 5 sind die Dichtungsabschnitte 8, 7 in einer Vertiefung der Wandung 4 angeordnet, dabei ist für den Dichtungsabschnitt 8 aus Intumeszenzmaterial die größte Vertiefung vorgesehen. Oberhalb des Dichtungsabschnitts 8 aus Intumeszenzmaterial ist ein Hohlraum 6 vorgesehen.In the first exemplary embodiment Figures 1 to 5 the sealing sections 8, 7 are arranged in a recess in the wall 4, with the largest recess being provided for the sealing section 8 made of intumescent material. A cavity 6 is provided above the sealing section 8 made of intumescent material.

Bei dem zweiten Ausführungsbeispiel in Figuren 6 bis 10 sind wiederum Vertiefungen in der Wandung 4 des Gehäuses 1 für die Dichtungsabschnitte vorgesehen. Ein erster Dichtungsabschnitt 7 aus Nichtintumeszenzmaterial sowie der Dichtungsabschnitt 8 aus Intumeszenzmaterial sind in einer Vertiefung angeordnet, ein zweiter Dichtungsabschnitt 7 aus Nichtintumeszenzmaterial ist in einer geringeren Vertiefung angeordnet. Dieser Abschnitt 7 aus Nichtintumeszenzmaterial steht zudem weiter in das Innere des Gehäuses 1 vor, dadurch bildet dieser Abschnitt 7 einen Anschlag für die Schwenkbewegung des Absperrelementes 2 aus. Auch bei diesem Ausführungsbeispiel ist ein Hohlraum 6 oberhalb des Abschnitts 8 aus Intumeszenzmaterial vorgesehen.In the second exemplary embodiment in Figures 6 to 10 In turn, recesses are provided in the wall 4 of the housing 1 for the sealing sections.
