Description

Die vorliegende Anmeldung betrifft eine Brandschutz-/Entrauchungseinrichtung mit einem Gehäuse, einer in diesem zwischen einer Offenstellung und einer Schließstellung verschwenkbar anordbaren Schließklappe und wenigstens einem in dem Gehäuse anordbaren Anschlag, wobei die Schließklappe und der Anschlag wenigstens teilweise aus einem Hitze und Feuer widerstehenden Material bestehen und wobei der Anschlag eine in Schließstellung die Schließklappe kontaktierende erste Dichtung aufweist.The present application relates to a fire / smoke extraction device comprising a housing, a closable in this between an open position and a closed position closing flap and at least one can be arranged in the housing stop, wherein the closing flap and the stop are at least partially made of a heat and fire resistant material and wherein the stop has a first seal contacting the closing flap in the closed position.

Derartige Brandschutz/Entrauchungseinrichtungen sind aus dem Stand der Technik bekannt. Die Schließklappe hat die Funktion eine Feuer- und Rauchausbreitung von einem Brandabschnitt in einen anderen durch ein Luftleitungssystem, das durch feuerwiderstandsfähige Wände und Decken hindurchführen kann, zu verhindern. Die Schließklappe wird ihrer Funktion nach auch als Brandschutzklappe und/oder Entrauchungsklappe bezeichnet.Such fire / smoke control devices are known from the prior art. The closing flap has the function of preventing the spread of fire and smoke from one compartment to another through an air duct system that can pass through fire resistant walls and ceilings. The closing flap is referred to its function as a fire damper and / or smoke control.

Eine Brandschutzklappe ist der praktischen Anwendung entsprechend (direkt oder indirekt über einen Leitungsabschnitt) mit einem feuerwiderstandsfähigen raumabschließenden Bauteil verbunden. Über einen eingebauten oder direkt mit der Brandschutzklappe verbundenen Mechanismus kann die Brandschutzklappe von der Stellung "geöffnet" in die Stellung "geschlossen" überführt werden. Die Brandschutzklappe enthält vorzugsweise eine thermisch ausgelöste Vorrichtung, die so konstruiert ist, dass sie auf einen Temperaturanstieg der Umgebungsluft reagiert und die Bewegung der Brandschutzklappe bei einer festgelegten Temperatur auslöst. Sie kann mit mechanisch, elektrisch, elektronisch oder pneumatisch betriebenen Mechanismen zusammenarbeiten, die innerhalb der Vorrichtung oder davon entfernt angeordnet sind.A fire damper is the practical application according to (directly or indirectly via a line section) connected to a fire-resistant raumabschließenden component. A built-in or directly connected to the fire damper mechanism, the fire damper can be transferred from the "open" position to the "closed" position. The fire damper preferably includes a thermally triggered device that is designed to respond to an increase in ambient air temperature and to initiate the movement of the fire damper at a predetermined temperature. It can be mechanical, electrical, electronic or pneumatically operated mechanisms located within or remote from the device.

Bei einer Entrauchungsklappe handelt es sich um ein Bauteil, welches innerhalb maschineller Rauchabzüge angeordnet ist und welches zur Entrauchung geöffnet werden muss. Sämtliche Bauteile von Entrauchungsklappen müssen im Wesentlichen aus Baustoffen der Klasse A nach DIN 4102 - 1 bestehen. Es dürfen keine intumeszierende Baustoffe verwendet werden. Entrauchungsklappen müssen eine Auslöseeinrichtung, die durch Rauchmelder ausgelöst wird, eine Handauslöseeinrichtung und eine Fernauslöseeinrichtung (z. B. Elektrohubmagnet, pneumatische Auslösung) besitzen. Die Energie zum Öffnen muss dauerhaft an der Klappe gespeichert sein. Unabhängig vom Betriebszustand der maschinellen Abzugsanlage müssen Entrauchungsklappen nach Auslösung selbständig und sicher öffnen und in Offenstellung verriegeln. Entrauchungsklappen für maschinelle Rauchabzüge aller Kategorien, die im Zuge von Entrauchungsleitungen mit notwendiger Feuerwiderstandsdauer eingesetzt werden, müssen eine entsprechende Feuerwiderstandsdauer aufweisen.A smoke control damper is a component which is arranged inside mechanical smoke extractors and which must be opened for smoke extraction. All components of smoke control dampers must consist essentially of building materials of class A according to DIN 4102-1. No intumescent building materials may be used. Smoke control dampers must have a tripping device that is triggered by smoke detectors, a manual release device and a remote release device (eg electric lift solenoid, pneumatic release). The energy to open must be stored permanently on the flap. Regardless of the operating state of the mechanical extraction system, smoke control dampers must open automatically and safely after activation and lock in the open position. Smoke dampers for mechanical smoke extractors of all categories, which are used in the course of smoke extraction ducts with the required fire resistance period, must have a corresponding fire resistance duration.

Eine Brandschutz-/Entrauchungseinrichtung kann über eine oder mehrere Schließklappen verfügen, welche jeweils zwischen einer Offenstellung und einer Schließstellung verschwenkbar in einem Gehäuse angeordnet sind. Zur Begrenzung der Verschwenkbarkeit einer einzelnen Schließklappe ist im Gehäuse ein Anschlag vorgesehen, an dem die jeweilige Schließklappe in Schließ- oder Offenstellung in Anlage kommt, wobei der Anschlag auf der Seite einer anliegenden Schließklappe eine Dichtung aufweist, so dass ein annähernd luftdichter Verschluss innerhalb des Systems ausgebildet werden kann. Die Dichtheit der Schließklappe in geschlossener Stellung ist durch genormte Prüfungen bei unterschiedlichen Temperaturzuständen nachzuweisen. Auf die entsprechenden Normen für Entrauchungsklappen DIN 18232 - 6 und Brandschutzklappen DIN EN 1366 - 2 sowie weitere flankierende Normen sei hiermit verwiesen.A fire protection / smoke extraction device may have one or more closing flaps, which are each arranged pivotably between a open position and a closed position in a housing. In order to limit the pivotability of a single closing flap, a stop is provided in the housing against which the respective closing flap comes into contact in the closed or open position, wherein the stop has a seal on the side of an adjacent closing flap, so that an approximately airtight closure within the system can be trained. The tightness of the closing flap in the closed position must be verified by standardized tests at different temperature conditions. Reference should be made to the corresponding standards for smoke control dampers DIN 18232 - 6 and fire dampers DIN EN 1366 - 2 as well as other flanking standards.

Es hat sich jedoch herausgestellt, dass herkömmliche Schließklappen auch in Schließstellung aufgrund der in Schließstellung auftretenden Druckdifferenz zwischen den beiden Seiten einer Schließklappe einen Luft- bzw. Rauchdurchlass ermöglichen. Dies kann in nachteiliger Weise dazu führen, dass dem Schutzbereich (Feuer abgewandten Seite) Rauchgase und ein Temperatureintrag zugeführt wird. Des Weiteren können auch umgekehrt dem Brandherd Luft und Sauerstoff zugeführt werden, was sich in beiden Fällen negativ auf den Schutzraum bzw. den Brandherd und somit die Brandentwicklung auswirkt.However, it has been found that conventional closing flaps, even in the closed position, allow an air or smoke passage in the closing position due to the pressure difference between the two sides of a closing flap. This can disadvantageously lead to the protection area (side facing away from the fire) flue gases and a temperature input is supplied. In addition, the source of fire can also be supplied with air and oxygen, resulting in both Negative impact on the shelter or the fire and thus the development of fire.

Ausgehend von diesem Stand der Technik ist es die Aufgabe der vorliegenden Erfindung, eine Brandschutz-/Entrauchungseinrichtung bereitzustellen, welche in Schließstellung weitestgehend luftundurchlässig ausgebildet ist, um die oben genannten Nachteile zu vermeiden.Based on this prior art, it is the object of the present invention to provide a fire / smoke extraction device which is formed in the closed position largely airtight, in order to avoid the above-mentioned disadvantages.

Diese Aufgabe wird erfindungsgemäß durch eine Brandschutz-/Entrauchungseinrichtung nach Anspruch 1 gelöst, bei der die Schließklappe erfindungsgemäß wenigstens eine zweite Dichtung aufweist.This object is achieved by a fire / smoke extraction device according to claim 1 , wherein the closing flap according to the invention comprises at least a second seal.

Somit weist die Brandschutz-/Entrauchungseinrichtung weitere Dichtungen auf, welche insbesondere die Schließklappe gegenüber Gehäuseabschnitten der Brandschutz-/Entrauchungseinrichtung abdichten, so dass nicht nur eine Abdichtung zwischen dem Anschlag und der Schließklappe erfolgt. Bei Verwendung der erfindungsgemäßen Brandschutz-/Entrauchungseinrichtung kommt es somit zu einem sicheren und luftdichten Verschluss eines Lüftungskanals eines Lüftungssystems, so dass eine hochwertige und sehr effektive Brandschutz-/Entrauchungseinrichtung geschaffen ist, die den heutigen Anforderungen genügt.Thus, the fire protection / smoke extraction on other seals, which in particular seal the closing flap against housing sections of the fire / smoke extraction, so that not only a seal between the stop and the closing flap takes place. When using the fire / smoke extraction device according to the invention thus results in a secure and airtight closure of a ventilation duct of a ventilation system, so that a high-quality and very effective fire / smoke extraction device is created, which meets today's requirements.

Die Form der Brandschutz-/Entrauchungseinrichtung kann dabei je nach den örtlichen Gegebenheiten variieren, so dass beispielsweise das Gehäuse einen eckigen, elliptischen oder kreisrunden Querschnitt aufweisen kann, so dass für ein jeweiliges Lüftungssystem eine entsprechend ausgebildete Brandschutz-/Entrauchungseinrichtung bereitgestellt werden kann. Natürlich sind die Schließklappe und der Anschlag der Formgebung des Gehäuses der Brandschutz-/Entrauchungseinrichtung angepasst.The shape of the fire protection / smoke extraction device can vary depending on the local conditions, so that, for example, the housing may have a polygonal, elliptical or circular cross section, so that for a respective ventilation system, a suitably trained fire / smoke extraction device can be provided. Of course, the closing flap and the stop of the shape of the housing of the fire / smoke extraction device are adapted.

Die erste Dichtung, welche zwischen dem Anschlag und der in Schließstellung an den Anschlag anliegenden Schließklappe angeordnet ist, kann dabei entweder an dem Anschlag, in seiner Längserstreckung verlaufend oder an einem Randbereich der Schließklappe angeordnet sein. Ebenso ist denkbar, dass sowohl der Anschlag, als auch die Schließklappe an einander zugewandten Bereichen eine Dichtung aufweisen, um einen Luftdurchlass weitestgehend zu unterbinden.The first seal which is arranged between the stop and the closing flap resting against the stop in the closed position can be arranged either on the stop, in its longitudinal extent or on an edge region of the closing flap. It is also conceivable that both the stop, as well as the closing flap on facing areas have a seal to prevent an air passage as far as possible.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist die Schließklappe zwei im Wesentlichen parallel zueinander angeordnete Großflächen und wenigstens eine im Wesentlichen senkrecht zu den Großflächen verlaufende Seitenfläche auf, wobei die zweite Dichtung an wenigstens einem Teil der Seitenfläche angeordnet ist. Die plattenförmig ausgestaltete Schließklappe weist somit zwei Großflächen auf, welche eine ebene, gewölbte oder ähnlich strukturierte Oberfläche aufweisen können, und welche an ihren Kanten mit wenigstens einer senkrecht zu den Großflächen verlaufenden Seitenfläche verbunden sind. Eine einzige Seitenfläche ist beispielsweise bei der Ausgestaltung der Brandschutz-/Entrauchungseinrichtung bzw. der Schließklappe mit einem kreisrunden oder elliptischen Querschnitt gegeben, wobei hingegen eine eckige Schließklappe mehrere Seitenflächen aufweist. Die zweite Dichtung ist an wenigstens einem Teil der Seitenfläche, vorzugsweise die Schließklappe umlaufend an dieser angeordnet. Dadurch findet nicht nur eine Abdichtung zwischen dem Anschlag und dem daran anliegenden Bereich der Schließklappe statt, sondern es wird der gesamte umlaufende Spalt zwischen der Schließklappe und dem Gehäuse abgedichtet, so dass ein Luftdurchlass durch die Brandschutz-/Entrauchungseinrichtung weitestgehend verhindert wird. Dabei kann die zweite Dichtung beispielsweise flächig auf die Seitenfläche aufgeklebt oder irgendwie anders befestigt sein, oder die Seitenfläche weist eine vorzugsweise die Schließklappe umlaufende Nut auf, welche die zweite Dichtung teilweise aufnimmt und an der Schließklappe hält.According to an advantageous embodiment of the invention, the closing flap has two substantially parallel to each other arranged large surfaces and at least one substantially perpendicular to the large surfaces extending side surface, wherein the second seal is disposed on at least a portion of the side surface. The plate-shaped flap designed thus has two large surfaces, which may have a flat, curved or similarly structured surface, and which are connected at their edges with at least one perpendicular to the large surfaces extending side surface. A single side surface is given, for example, in the embodiment of the fire protection / smoke extraction device or the closing flap with a circular or elliptical cross section, whereas, however, a square closing flap has a plurality of side surfaces. The second seal is disposed on at least a part of the side surface, preferably the closing flap circumferentially thereto. As a result, not only does a seal between the stop and the adjoining region of the closing flap take place, but the entire circumferential gap between the closing flap and the housing is sealed, so that an air passage through the fire protection / smoke extraction device is largely prevented. In this case, the second seal, for example, glued flat on the side surface or be attached somehow different, or the side surface has a preferably the closing flap circumferential groove which partially receives the second seal and holds on the closing flap.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Schließklappe zwei im Wesentlichen kongruent zueinander ausgebildete Klappenelemente aufweist, die parallel zueinander anordbar und miteinander verbindbar sind. Durch diese doppelte Ausgestaltung der Schließklappe ist eine hochwertige Hitze- und Feuerbarriere gegeben, welche zudem eine einfache Anordnung der Schließklappe an entsprechenden, diese antreibenden Antriebeinrichtung gewährleistet und zudem durch Wahl der Dicke und des Materials der Klappenelemente ein hohes Maß an Ausgestaltungsvielfalt gemäß den jeweiligen Gegebenheiten und Anforderungen bietet. Die beiden Klappenelemente können miteinander verklebt, verschraubt oder verklammert sein, um eine stabile Schließklappe auszubilden.A further advantageous embodiment of the invention provides that the closing flap has two flap elements which are essentially congruent to one another and which can be arranged parallel to one another and connected to one another. This double design of the closing flap is given a high-quality heat and fire barrier, which also ensures a simple arrangement of the closing flap to corresponding, this driving drive device and also by choosing the thickness and the material of the flap elements a high degree of design variety according to the particular circumstances and Offers requirements. The two flap elements can be glued together, screwed or clamped together to form a stable closing flap.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass zwischen den Klappenelementen eine Platte aus einem Hitze und Feuer widerstehenden Material angeordnet ist. Diese Platte erhöht ebenfalls die Ausgestaltbarkeit der Schließklappe und deren Eigenschaften bezüglich des Hitze- und Feuerwiderstandes. Zudem kann durch diese Ausgestaltung der Schließklappe eine Nut an der Seitenfläche derselben ausgebildet werden, indem die Platte eine kleinere Fläche als die Klappenelemente auf-weist, wodurch zwischen den Klappenelementen im Randbereich derselben eine Nut er-zeugt wird, an der die zweite Dichtung auf geeignete Art und Weise angeordnet werden kann.According to a further advantageous embodiment of the invention it is provided that between the flap elements a plate of a heat and fire resisting material is arranged. This plate also increases the Ausgestaltbarkeit the closing flap and their properties in terms of heat and fire resistance. In addition, this embodiment of the closure flap, a groove on the side surface of the same are formed by the plate has a smaller area than the flap elements, thereby generating a groove between the flap elements in the edge region thereof, on which the second seal on suitable Way can be arranged.

Ferner ist nach einer vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass die Brandschutz-/Entrauchungseinrichtung eine Antriebeinrichtung aufweist, mittels der die Schließklappe verschwenkbar ist. Die Antriebeinrichtung kann dabei mit mechanisch, elektrisch, elektronisch und/oder pneumatisch betriebenen Mechanismen zusammenarbeiten, die innerhalb der Antriebeinrichtung oder davon entfernt angeordnet sind. Die Brandschutz-/Entrauchungseinrichtung weist bevorzugterweise eine Auslöseeinrichtung auf, welche bei Hitze- und/oder Feuereinwirkung das Schließen oder gegebenenfalls auch Öffnen der Schließklappe auslöst.Furthermore, it is provided according to an advantageous embodiment of the invention that the fire protection / smoke extraction device has a drive device by means of which the closing flap is pivotable. The drive device can cooperate with mechanically, electrically, electronically and / or pneumatically operated mechanisms which are arranged within the drive device or away from it. The fire protection / smoke extraction device preferably has a triggering device, which triggers the closing or possibly also opening of the closing flap when exposed to heat and / or fire.
