Brandschutzklappen mit Stellantrieben und Federrücklauf werden als Sicherheitsstellglieder eingesetzt. Die Stellglieder werden im Normalbetrieb durch den integrierten Stellantrieb in Offenstellung gebracht und in dieser Position gehalten. Im Störfall oder zwecks Überprüfung soll das Stellglied seine Sicherheitsstellung einnehmen und in dieser Stellung gegenüber kanalseitigen Einwirkungen verriegelt werden. Das Einnehmen der Sicherheitsstellung erfolgt bei Unterbruch der Stromversorgung, sei es durch einen Stromausfall oder durch einen gezielten, via Steuerelektronik und Sensoren ausgelösten Stromunterbruch. Ein solches Sicherheitsstellglied kann beispielsweise dazu benutzt werden, die Ausbreitung von Feuer und Rauch in Lüftungssystemen zu verhindern und Durchbrüche für Lüftungskanäle in Brandschutzmauern im Brandfall feuerfest abzudichten.Fire dampers with actuators and spring return are used as safety actuators. The actuators are in normal operation by the integrated actuator placed in open position and held in this position. in the Incident or for verification purposes, the actuator should be its Occupy security position and in this position opposite Channel-side actions are locked. The ingestion the safety position takes place at interruption of the Power supply, either through a power outage or through a targeted, via control electronics and sensors triggered Power failure. Such a safety actuator can for example, the spread of fire and to prevent smoke in ventilation systems and breakthroughs for ventilation ducts in fire walls in case of fire fireproof seal.

Stellantriebe mit Federrücklauf für Brandschutzklappen sind in der Klima-, Lüftungs- und Regeltechnik hinlänglich bekannt. Als nächsten Stand der Technik kann die Patentanmeldung EP 0 699 095 B1 (D1) herangezogen werden. D1 offenbart eine Brandschutzklappe mit zugehörigem Kontrollsystem für mindestens eine Klappe. Ein Nachteil der bekannten Brandschutzklappen ist die komplizierte und zeitraubende werkseitige Montage und Demontage der Klappe und des Stellantriebes sowie der Austausch des Stellantriebes infolge Wartung bei eingemauerter Brandschutzklappe. Ausserdem weisen die meisten Vorrichtungen relativ grosse Dimensionen auf und sind aufgrund ihres aufwändigen Aufbaus teuer in der Herstellung. Die Verriegelung in der offenen als auch in der Sicherheitsstellung wird in der Praxis häufig mit ebenfalls aufwändigen innen oder aussen an der Klappe angebrachten Gestängen bewerkstelligt. Diese Gestänge erschweren die Montage und müssen justiert werden. Ausserdem gelten sie als bewegliche Teile und stellen daher ein Sicherheitsrisiko dar. Actuators with spring return for fire dampers are in the air conditioning, ventilation and control technology well known. As the closest prior art, the patent application EP 0 699 095 B1 (D1). D1 discloses a fire damper with associated control system for at least one flap. A disadvantage of the known fire dampers is the complicated and time-consuming factory Assembly and disassembly of the flap and the actuator and the replacement of the actuator due to maintenance at walled fire damper. In addition, most have Devices relatively large dimensions and are due their elaborate construction expensive to manufacture. The Lock in the open as well as in the safety position In practice it often comes with a complex interior or externally attached to the flap mounted poles accomplished. These rods make assembly difficult and must to be adjusted. In addition, they are considered moving parts and therefore pose a security risk.

Der Stellantrieb soll zudem möglichst kompakt dimensioniert sein.The object of the present invention is to provide of electrically operated fire dampers without the above-mentioned disadvantages of conventional systems. The fire damper with actuator should be cheap, with as little as possible movable parts can be made, the installation and expansion should be possible in the simplest way, for example even with a walled fire damper.

Fig. 1 zeigt ein erstes Ausführungsbeispiel einer Brandschutzklappe 1, im Folgenden Klappe 1 genannt. In geöffneter Position steht das Klappenblatt 11 in Richtung des Kanals 2, so dass im Wesentlichen der ganze, hier rechteckige, Querschnitt des Kanals 2 freigegeben ist. Das Klappenblatt 11 hat dieselbe geometrische Form wie der Querschnitt des Kanals 2, ist aber um soviel kleiner, dass das Klappenblatt 11 mit einer im Wesentlichen 90°-Drehung in die den Kanal 2 schliessende Sicherheitsstellung gebracht werden kann, ohne dass es den Kanal 2 berührt. Das Klappenblatt 11 ist beispielsweise um eine vertikale Achse drehbar gelagert. Ein obenliegender, teilweise in eine über dem Durchbruch für den Kanal 2 befindliche Maueraussparung eingeschobener Stellantrieb 4 kann das Klappenblatt 11 um einen im Wesentlichen rechten Winkel verdrehen. Der Stellantrieb 4 wird bei Montage der Klappe 1 innerhalb einer Brandschutzmauer 5 lediglich in eine Maueraussparung eingeschoben und anschliessend zur Drehmomentsicherung, beispielsweise mit einer Schraube 6, möglichst fern der Klappenachse 3 und gut zugänglich am Kanal 2 fixiert. Es ist im Erfindungsgedanken enthalten, dass der Stellantrieb 4 je nach Zugänglichkeit auch unter dem Kanal 2 oder seitlich am Kanal 2 mit horizontaler Klappenachse 3 angebracht werden kann.Fig. 1 shows a first embodiment of a fire damper 1, hereinafter called flap 1. In open Position is the damper blade 11 in the direction of the channel 2, so that essentially the whole, here rectangular, cross-section of the channel 2 is released. The damper blade 11 has the same geometric shape as the cross-section of the channel 2, but is so much smaller that the damper blade 11 with a essentially 90 ° rotation into the channel 2 closing Security position can be brought without it touched channel 2. The damper blade 11 is for example rotatably mounted about a vertical axis. An overhead, partly located in a channel above the breakthrough for the channel 2 Wall recess inserted actuator 4 can Turn damper blade 11 about a substantially right angle. The actuator 4 is in mounting the flap 1 within a fire wall 5 only in a wall recess inserted and then to the torque lock, for example, with a screw 6, as far as possible Flap axle 3 and easily accessible fixed to the channel 2. It is included in the idea of the invention that the actuator 4 each after accessibility also under the channel 2 or laterally on Channel 2 with horizontal flap axis 3 are attached can.

In Fig. 2a,b wird ein erstes Ausführungsbeispiel des Klappenblattes 11 in Sicherheitsstellung gezeigt. Das Klappenblatt 11 weist oben und unten eine Nut 7 auf. Die Klappenachse 3 ist nicht über die ganze Kanalhöhe durchgehend, sondern wird durch zwei kurze Achsendstücke 8 und das Klappenblatt 11 gebildet. Die Achsendstücke 8 sind kraftschlüssig mit je einem zur Richtung der Klappenachse 3 rechtwinklig angebrachten Kamm 13 verbunden. Für die Montage des Klappenblattes 11, müssen nun lediglich die Achsendstücke 8 in ihre Lager 9, 10 im Kanalboden und im Stellantrieb 4 eingesetzt werden. Im Kanalboden ist ein Drehlager 9, beispielsweise ein Gleitlager, zur Aufnahme des unteren Achsendstückes 8 eingelassen und das obere, beispielsweise einen quadratischen Achsquerschnitt aufweisende Achsendstück 8 wird formschlüssig in die Hohlachse der Lastmomentsperre 18 eingeführt. Anschliessend kann das Klappenblatt 11 mit den Nuten 7 in die beiden Kämme 13 eingeführt werden. Die Nuten 7 sind nicht über die ganze Länge des Klappenblattes 11 durchgehend, sondern sie enden auf einer Klappenblatthälfte je nach Länge der Kämme 13 so, dass die Kämme 13 in der richtigen Position an den Enden der Nuten 7 anschlagen. Auf diese Weise kann das Klappenblatt 11 von einer Seite her auf die Kämme 13 aufgeschoben werden, bis zur richtigen, durch die Enden der Nuten 7 definierte Position. Das richtig positionierte und justierte Klappenblatt 11 kann sodann an den Kämmen 13 und damit an den Achsendstücken 8 mittels einer Verbindung 12 fixiert und so gegen nachträgliche horizontale Verschiebungen gesichert werden. Diese Verbindung 12 kann beispielsweise mittels Schraube direkt in den Kamm 13 erfolgen. Eine weitere erfindungsgemässe Ausführung zur Verhinderung einer Verschiebung des Klappenblattes in Richtung der Nut 7, besteht darin, dass kraftschlüssig mit dem Achsendstück 8 verbundene u-förmige Führungsteile 24, beispielsweise aus Stahlblech gefertigt, das Klappenblatt 11 in Achsnähe umfassen und diese Führungsteile 24 bei richtig positioniertem Klappenblatt 11 mit dem Klappenblatt 11 mittels Verbindungen 12 verbunden werden. Nach der Montage des Klappenblattes 11 ist es möglich, beispielsweise zur Erfüllung von Brandschutzvorschriften, die Teile der Nut 7, welche nicht durch den Kamm 13 ausgefüllt sind, beispielsweise mit einer feuerfesten Dichtung zu füllen. Der Kamm 13 kann die Nut 7 auch über die volle Klappenbreite ausfüllen. Üblicherweise schlagen die Klappenblätter 11 beim Einnehmen der Offenstellung gegen Anschläge an der Kanalwand. Diese Anschläge sind hier nicht nötig, da der Stellantrieb 4 die Klappe 1 genau in Offenstellung, normalerweise in Richtung des Kanals 2, positioniert und gegenüber von auf das Klappenblatt 11 wirkenden Kräften ausgelöste Drehmomente verriegelt.In Fig. 2a, b is a first embodiment of the damper blade 11 shown in safety position. The damper blade 11 has a groove 7 at the top and bottom. The flap axis 3 is not continuous throughout the channel height, but will formed by two short Achsendstücke 8 and the damper blade 11. The Achsendstücke 8 are non-positively with one each attached to the direction of the flap axis 3 at right angles Comb 13 connected. For the assembly of the damper blade 11, now only the Achsendstücke 8 in their bearings 9, 10th be used in the channel bottom and in the actuator 4. In the canal floor is a pivot bearing 9, for example, a sliding bearing, embedded for receiving the lower Achsendstückes 8 and the upper, for example, a square axle cross-section having Achsendstück 8 is positively in the hollow axle the load torque lock 18 introduced. Subsequently, the Damper blade 11 is inserted with the grooves 7 in the two ridges 13 become. The grooves 7 are not over the entire length of the Damper blade 11 continuously, but they end on a Flap half, depending on the length of the combs 13 so that the Combs 13 in the correct position at the ends of the grooves. 7 attacks. In this way, the damper blade 11 of a Side be pushed onto the ridges 13, to the correct, defined by the ends of the grooves 7 position. The properly positioned and adjusted damper blade 11 can then at the ridges 13 and thus at the Achsendstücken. 8 fixed by means of a compound 12 and so against subsequent horizontal shifts are saved. This connection 12, for example, by means of screw directly into the Comb 13 done. Another embodiment of the invention for preventing displacement of the damper blade in Direction of the groove 7, is that frictionally with the axle end piece 8 connected U-shaped guide parts 24, For example, made of sheet steel, the damper blade 11th close to the axis and these guide parts 24 at right positioned damper blade 11 with the damper blade 11 by means of Connections 12 are connected. After the assembly of the Damper blade 11, it is possible, for example, to meet from fire regulations, the parts of the groove 7, which not filled by the comb 13, for example with to fill a refractory seal. The comb 13 can the Fill groove 7 also over the full width of the flap. Usually beat the damper blades 11 when taking the open position against attacks on the canal wall. These attacks are not necessary here, since the actuator 4, the flap 1 exactly in the open position, normally in the direction of channel 2, positioned and opposite to acting on the damper blade 11 Forces triggered torques locked.

Im Folgenden sei die Vorgehensweise bei Montage der Klappe 1 noch einmal kurz zusammengefasst. Der Stellantrieb 4 wird bei Montage innerhalb einer Brandschutzmauer 5 bündig in eine Maueraussparung am Kanal 2 eingeschoben und mit einer Schraube 6 am Kanal 2 befestigt. Anschliessend wird der Stellantrieb 4 durch Stromzufuhr oder per Handaufzug in Offenstellung gebracht, die beiden Achsendstücke 8 werden in die Lager 9, 10 eingesetzt, das Klappenblatt 11 wird mit den Nuten 7 in die Kämme 13 der Achsendstücke 8 eingefahren und schliesslich mittels Verbindungen 12 und je nach Ausführung mittels Führungsteilen 24 an den Achsendstücken 8 befestigt. Die Montage des Stellantriebes 4 und des Klappenblattes 11 kann vollständig von der Seite des Stellantriebes 4 aus erfolgen.Below is the procedure for mounting the flap. 1 briefly summarized again. The actuator 4 is at Installation within a fire wall 5 flush in one Wall recess inserted on the channel 2 and with a screw 6 attached to the channel 2. Subsequently, the actuator 4 by power or by manual winding in open position brought, the two Achsendstücke 8 are in the camp 9, 10 inserted, the damper blade 11 is with the grooves 7 in the combs 13 of Achsendstücke 8 retracted and finally by means of connections 12 and depending on the design by means of guide parts 24 attached to the Achsendstücken 8. The assembly the actuator 4 and the damper blade 11 can completely take place from the side of the actuator 4 from.

Fig. 3 zeigt schematisch den Aufbau eines ersten Ausführungsbeispiels des Stellantriebes 4. Er besteht im Wesentlichen aus lediglich vier Komponenten. Ein Elektromotor 15, welcher mit einem Federrücklauf 16 und über ein stark untersetzendes Getriebe 17 (1:500 bis 1:10'000) und eine Lastmomentsperre 18 mit der Klappenachse 3 gekoppelt ist. Die benötigte Untersetzung des Getriebes 17 hängt von der Leistungsfähigkeit des Elektromotors 15 ab. Im Normalbetrieb öffnet der Elektromotor 15 via Getriebe 17 das Klappenblatt 11 und zieht gleichzeitig den Federrücklauf 16 auf. Der Elektromotor 15 ist die eigentliche Antriebsquelle des Stellantriebes 4. Für das Anfahren und Erhalten der Offenstellung des Klappenblattes 11 muss der Elektromotor 15 ununterbrochen mit Strom versorgt werden. Bei Erreichen der Offenstellung wird das Klappenblatt 11 und damit auch der Elektromotor 15 mechanisch am weiter drehen gehindert. Der weiter unter Strom stehende und nun blockierte Elektromotor 15 erzeugt ein genügend grosses Drehmoment, um die rücktreibende Kraft des gespannten Federrücklaufs 16 auszugleichen. Bei unterbrochener Stromzufuhr dreht der gespannte Federrücklauf 16 das Klappenblatt 11 via Getriebe 17 in die geschlossene Sicherheitsstellung zurück, wobei der Elektromotor 15 infolge der fixen Kupplung ebenfalls rückwärts gedreht wird. Als Federrücklauf 16 wird typischerweise eine Spiralfeder verwendet, es sind aber auch andere Federn zur Speicherung der benötigten Rücklaufenergie denkbar und erfindungsgemäss. Für Wartungsarbeiten oder Inbetriebnahme bei nicht unter Strom stehendem Stellantrieb 4 verfügt der Federrücklauf 16 über einen Handaufzug zum Öffnen des Klappenblattes 11, beispielsweise mittels einer Innensechskantschraube. Mittels einer Arretierungsvorrichtung kann der von Hand gespannte Federrücklauf 16 blockiert werden, wobei sichergestellt sein muss, dass diese Blockierung bei Einsetzen der Stromversorgung sofort und zuverlässig aufgehoben wird. Dem Fachmann sind solche Arretierungsvorrichtungen bekannt und werden an dieser Stelle nicht näher ausgeführt. Die Klappenachse 3 wird über eine Lastmomentsperre 18 angetrieben. Fig. 3 shows schematically the structure of a first embodiment the actuator 4. It consists essentially from only four components. An electric motor 15, which with a spring return 16 and over a strongly declining Gear 17 (1: 500 to 1: 10'000) and a load torque lock 18 is coupled with the flap axis 3. The required reduction of the transmission 17 depends on the performance of the Electric motor 15 off. In normal operation, the electric motor opens 15 via gear 17, the damper blade 11 and pulls simultaneously the spring return 16. The electric motor 15 is the actual one Drive source of the actuator 4. For starting and getting the open position of the damper blade 11 must the Electric motor 15 are continuously powered. at Reaching the open position, the damper blade 11 and thus Also, the electric motor 15 mechanically prevented from turning further. The further energized and now blocked Electric motor 15 generates a sufficiently large torque to to compensate for the restoring force of the tensioned spring return 16. When power is interrupted, the cocked turns Spring return 16 the damper blade 11 via gear 17 in the closed safety position back, the electric motor 15 due to the fixed clutch also backwards is turned. As spring return 16 is typically a Spiral spring used, but there are other springs for Storage of the required return energy conceivable and according to the invention. For maintenance or commissioning not energized actuator 4 has the spring return 16 via a manual winding to open the damper blade 11, for example by means of a hexagon socket screw. By means of a locking device can be stretched by hand Spring return 16 are blocked, being ensured must be that this blocking at the onset of Power supply is lifted immediately and reliably. the Those skilled in such locking devices are known and will not be explained here. The flap axis 3 is driven by a load torque lock 18.

Lastmomentsperren 18 sind Stand der Technik und werden daher an dieser Stelle nicht näher beschrieben. Sie ermöglichen einen ungehinderten Antrieb eines Maschinenteils in beiden Drehrichtungen, während rückwirkende Drehmomente des getriebenen Teils auf den Antrieb in beiden Drehrichtungen gesperrt werden. Die Lastmomentsperre 18 gestattet also freie Momentübertragung in der Antriebsrichtung, sperrt jedoch Drehmomentrückwirkung vom Antriebsteil her. Sie ist nötig, damit das Klappenblatt 11 nicht durch darauf wirkende Kräfte bewegt werden kann.Lastmomentsperren 18 are prior art and therefore not described in detail here. They allow one unimpeded drive of a machine part in both Turning directions, while retroactive torques of the driven Partly locked to the drive in both directions of rotation become. The load torque lock 18 thus allows free torque transmission in the drive direction, but locks Torque reaction from the drive part. It is necessary so that the damper blade 11 is not by forces acting on it can be moved.

Für die Anordnung und Koppelung von Elektromotor 15, Federrücklauf 16 und stark untersetzendem Getriebe 17 sind dem Fachmann viele Varianten bekannt. Diese sind im Erfindungsgedanken mit eingeschlossen. Beispielsweise kann der Elektromotor 15 auch direkt den Federrücklauf 16 spannen, welcher wiederum mittels Getriebe 17 und Lastmomentsperre 18 mit der Klappenachse 3 gekoppelt ist.For the arrangement and coupling of electric motor 15, spring return 16 and strongly reducing gear 17 are the Professional known many variants. These are in the spirit of the invention including. For example, the electric motor 15 also directly tension the spring return 16, which in turn by means of gear 17 and load torque lock 18 with the Damper shaft 3 is coupled.

Fig. 4 zeigt die auf der Klappenachse 3 montierte Lastmomentsperre 18. Mechanische Anschläge 20 an beiden Seiten eines im Wesentlichen rechtwinkligen Segmentes, beispielsweise dem Abtriebrad 25, verunmöglichen ein Überdrehen des Klappenblattes 11 beim Anfahren der Sicherheitsstellung oder der Offenstellung. Diese Anschläge 20 des Abtriebrades 25 im Stellantrieb 4 machen, wie oben erwähnt, Klappenanschläge im Kanalinnern überflüssig, was sich in vereinfachter Montage niederschlägt. Zusätzlich werden beim Erreichen sowohl der Sicherheitsstellung als auch der Offenstellung, beispielsweise auf der Lastmomentsperre 18 liegende, Endschalter oder Sensoren 21 betätigt, welche die Information über die Klappenstellung beispielsweise an eine elektronische Steuerung und Regelung liefern können. Diese Information kann aber beispielsweise auch für die Regelung des Drehmomentes des Elektromotors 15 in Offenstellung des Klappenblattes 11 verwendet werden. Für die Brandschutzfunktion der Klappe 1 sind Endschalter oder Sensoren 21 nicht notwendig.Fig. 4 shows the mounted on the damper shaft 3 Lastmomentsperre 18. Mechanical stops 20 on both sides of a substantially rectangular segment, for example the output gear 25, make impossible over-rotation of the damper blade 11 when approaching the safety position or the open position. These stops 20 of the output gear 25 in the actuator 4, as mentioned above, flap stops inside the channel superfluous, which is reflected in simplified assembly. Additionally, when reaching both the safety position as well as the open position, for example on the load torque lock 18 lying limit switches or sensors 21 actuates which information about the flap position for example, to an electronic control and regulation can deliver. This information can but for example also for the regulation of the torque of the electric motor 15 are used in the open position of the damper blade 11. For the fire protection function of the flap 1 are limit switches or sensors 21 are not necessary.

Fig. 5 zeigt eine erste Möglichkeit, wie eine vollständige Dichtung des Klappenblattes 11 im Brandfall, erreicht werden kann. Dies geschieht mittels thermisch aktivierter expandierender Stoffe 14, welche beispielsweise an den Klappenblatträndern angebracht sind. Diese Stoffe 14, beispielsweise Schäume, expandieren bei hohen Temperaturen und schliessen dadurch den verbleibenden schmalen Spalt zwischen Kanalwand und Klappenblatt 11 luftdicht ab. Der Vorgang ist irreversibel. Das nun festgeklebte Klappenblatt 11 muss anschliessend herausgebrochen und durch ein neues ersetzt werden. In Fig. 6 ist eine andere Möglichkeit zur vollständigen Dichtung des Klappenblattes 11 im Brandfall dargestellt. Der thermisch expandierende Stoff 14 wird auf Anschlägen im Kanalinnern angebracht.Fig. 5 shows a first possibility, such as a complete Seal of the damper blade 11 in case of fire, can be achieved can. This is done by means of thermally activated expanding Substances 14, which, for example, on the flap leaf edges are attached. These substances 14, for example Foams, expand at high temperatures and close thereby the remaining narrow gap between the channel wall and damper blade 11 airtight. The process is irreversible. The now glued flap leaf 11 must then be broken out and replaced with a new one. In Fig. 6 is another way to complete the seal of the Damper blade 11 shown in case of fire. The thermally expanding Fabric 14 is applied to stops inside the channel.
