Definitions
- the invention relates to a fire protection fastening device for fastening a door operator. Furthermore, the invention shows arrangements comprising a door operator together with a fire protection fastening device.
- Door operators are used to close and/or open doors.
- door closers and door drives are referred to as door actuators.
- a spring accumulator is usually charged by the manual opening movement. The energy stored in this way is used to close the door.
- the door drive for example, the door can be opened and/or closed independently by means of electromechanics or hydraulics.
- Door operators are usually attached to a mounting surface, ie on the door leaf or the frame or the wall.
- a mounting surface ie on the door leaf or the frame or the wall.
- flammable fluids such as hydraulic oils
- Appropriate measures should be taken to prevent the fluid in the door actuator from heating up too much in the event of a fire and potentially igniting it.
- the invention describes a fire protection fastening device for fastening a door operator.
- the door operator is a door closer or a door drive.
- the door operator must be attached to a mounting surface. This mounting surface is formed in particular by a door, frame or wall.
- the fire protection fastening device includes a frame.
- the frame is designed to be arranged between the door operator and the mounting surface. If there is no separate mounting plate, the door operator lies directly on the front of the frame. The back of the frame faces the mounting surface; is particularly close to the mounting surface.
- a mounting plate can be used between the frame of the fire protection attachment and the door operator. In particular, the mounting plate is screwed to the frame of the fire protection fastening device and the door operator is fastened to the mounting plate.
- the frame of the fire protection fastening device is an integral part of the door operator. This configuration will also be explained in detail.
- a mounting axis is defined to describe the invention.
- the mounting axis is perpendicular to the frame, particularly perpendicular to the back of the frame. Furthermore, the mounting axis is perpendicular to the mounting surface. For example, the mounting axis is parallel to the screws used to bolt the frame to the mounting surface. According to an alternative definition, the mounting axis is perpendicular to the output axis of the door operator.
- the door operator can be connected to the door or wall via this output shaft, for example via a linkage.
- At least one reaction chamber is formed in the frame of the fire protection fastening device.
- the frame has several reaction chambers.
- two, three, four, five, six, seven or eight reaction chambers are provided in the frame.
- the invention is usually described using a reaction chamber, it always being provided that the several reaction chambers are of identical design.
- the reaction chambers can differ in their size, so that, depending on the geometric design of the fire protection fastening device, as many reaction chambers as possible with the largest possible area can be used.
- the respective reaction chamber is fully delimited by the frame.
- the depth of the reaction chamber extends parallel to the mounting axis. Accordingly, the circumference of the reaction chamber is also defined with respect to an axis parallel to the assembly axis.
- the reaction chamber is open at the rear and/or the front of the frame. If the reaction chamber on both sides, i. H. on the front and on the back, is open, it is a through hole in the frame. If the reaction chamber is only open on one of the two sides, it is in particular a pocket formed in the frame.
- a drive element is arranged in each reaction chamber.
- the drive element is made of thermally intumescent material.
- the drive element is designed to push the door actuator away from the mounting surface when it is thermally activated, that is to say when it is heated accordingly.
- the thermally activatable material of the drive element can be activated in a temperature range of 90°C to 200°C.
- the drive element is in particular a flat, plate-shaped material that can be cut to any size. Since this material is available in certain thicknesses, it is preferably provided that several layers are superimposed to form the drive element. The several layers then together form a drive element.
- the volume of this material increases, for example by foaming. Due to the fact that the drive element is arranged in the reaction chamber and due to the fact that the reaction chamber is completely delimited by the frame, the drive element only expands in a direction parallel to the mounting axis. The expansion of the drive element in a direction perpendicular thereto is blocked by the full-circumferential limitation by the frame.
- the frame can be arranged as an independent component between the door operator and the mounting surface. If necessary, a mounting plate can be located between the frame and the door operator. In this arrangement of the frame, the reaction chamber can be open at both the front and the back. What is decisive is that, when thermally activated, the drive element expands in the direction parallel to the mounting axis, as a result of which the door actuator is pushed away from the mounting surface. Whether the frame is pushed away with it or remains on the mounting surface side is not relevant for the basic function of the invention.
- the reaction chamber is open at the rear in order to push the door operator together with the integral frame away from the mounting surface.
- the door actuator When the drive element or the several drive elements in the individual reaction chambers are thermally activated, the door actuator is pushed away from the mounting surface, with the external threads on the screws or the associated internal threads breaking, for example. This releases the door operator from the mounting surface, i.e. from the door, frame or wall. In particular, it is assumed that the door operator is on the side of the door away from the fire. Detaching the door operator from its mounting surface avoids overheating the door operator, thereby avoiding ignition of the fluid in the door operator.
- the fire protection fastening device has a piston plate arranged in the reaction chamber.
- the piston plate is arranged in the reaction chamber in such a way that the mounting axis is orthogonal to the piston plate. If several reaction chambers are used, there is a drive element in each reaction chamber and a piston plate that is to be used preferably.
- the piston plate is formed from a rigid material and serves to be displaced by the drive element when the drive element is thermally activated. It is provided in particular that the piston plate is guided in the reaction chamber. The direction of displacement is in particular parallel to the assembly axis.
- the gap between the piston plate and the reaction chamber should preferably be kept as small as possible so that the intumescent material of the drive element does not swell past the piston plate through the gap.
- the piston plate can be arranged on the front or the rear of the drive element. Furthermore, it is also possible to arrange a piston plate on both sides of the drive element. Accordingly, two piston plates are then provided per reaction chamber.
- the piston plates can also be referred to as pressure distribution plates or pressure modulator plates, since they ensure that the pressure applied by the drive element is transmitted over as large an area as possible. They also ensure that the drive element is not uselessly distributed in cavities, for example the jagged rear side of a door operator, in the event of thermal activation.
- the piston plate is made of metal, for example aluminum. This results in a stiff, lightweight piston plate that is easy to manufacture.
- a thermally insulating design of the fire protection fastening device is advantageous.
- the heat input from the mounting surface into the drive element should be as resistance-free as possible.
- any further heat conduction, especially in the direction of the door operator, should be prevented if possible will.
- a piston plate, which is arranged between the drive element and the door operator is made of non-metallic, thermally insulating material.
- the piston plate can also be multi-layered, with at least one layer being made of non-metallic, thermally insulating material.
- a piston plate, which is arranged between the drive element and the mounting surface is made of metallic, thermally conductive material. This ensures that heat is transferred quickly from the mounting surface to the drive element in order to ensure an early increase in volume of the intumescent material. It can thus be provided that the drive element is surrounded by two different piston plates, in particular by two piston plates with different thermal conductivity.
- the thermally insulating material in the piston plate it is preferably provided that at least one insulating plate made of non-metallic, thermally insulating material is placed on at least one side of the piston plate.
- the insulation panel is preferably made of a fiber composite material.
- the insulation plate When the insulation plate is inserted between the piston plate and the drive element, it is located in particular in the reaction chamber. If the insulating plate is placed on the side of the piston plate facing away from the drive element, it can also be located outside the reaction chamber.
- the single reaction chamber has a cross-sectional area perpendicular to the mounting axis.
- This cross-sectional area of the reaction chamber is in particular rectangular, since as many reaction chambers or reaction chambers with a large area as possible can be distributed over the frame with this geometric configuration. However, other cross-sectional areas are also possible. However, it is preferably provided that the drive element and/or the piston plate and/or the insulating plate extends/extend over the entire cross-sectional area.
- the reaction chamber is preferably on both sides, i. H. on the front and on the back, open.
- the reaction chamber is open on both sides over the entire cross section.
- the open rear of the reaction chamber has the advantage that the drive element can be in direct contact with the mounting surface. As a result, the drive element is heated as quickly and adequately as possible in the event of a fire.
- the drive element can spread out in the direction of the door operator or push the piston plate in the direction of the door operator via the open front side.
- the fire protection fastening device is designed as flat as possible and is designed as far as possible in such a way that it can be arranged inconspicuously between the door operator and the mounting surface.
- a depth of each reaction chamber is defined perpendicular to the mounting axis. This depth of the reaction chamber is preferably between 1 mm and 30 mm, in particular between 5 mm and 20 mm. This provides sufficient installation space to arrange the drive element, possibly also the piston plate, in the reaction chamber.
- the cross-sectional area of the individual reaction chambers is defined perpendicular to the assembly axis. This is preferably between 400 mm 2 and 50,000 mm 2 ; preferably between 900 mm 2 and 10,000 mm 2 .
- the sum of all cross-sectional areas of all reaction chambers is preferably at least 2,500 mm 2 , in particular at least 5,000 mm 2 .
- the frame is not an integral part of the door operator, but is arranged between the mounting surface and the door operator or mounting plate. It is provided in particular that the frame has first attachment points for screwing to the mounting surface. Furthermore, second attachment points are formed in the frame, at which the door operator or any mounting plate can be attached to the frame.
- the attachment points are, in particular, through-holes. In particular at the second fastening points, the through-holes preferably have an internal thread.
- the fastening points can also be formed by threaded rods, for example.
- first and second attachment points which are closest to one another preferably form a pair.
- two first and two second attachment points are provided on the right side of the frame.
- two first and two second attachment points are provided on the left side of the frame. This means there are two pairs on each side of the frame.
- the distance between the attachment points of a pair is as small as possible.
- the distance between the first attachment point and the second attachment point of the respective pair is at most 5 times, preferably at most 4 times, the thickness of the frame.
- the thickness of the frame is defined parallel to the mounting axis.
- the frame at its thickest point is decisive.
- the average thickness of the frame in the area between the attachment points of a pair is decisive. If the distance between the attachment points of a pair is too great, it can happen that only the frame deforms without the door operator detaching from the frame.
- the invention also includes a first arrangement with a door operator and the fire protection attachment device described above, the frame of the fire protection attachment device being designed as an integral part of the door operator.
- the door operator has a housing; for example from die casting.
- the housing there is in particular at least one hydraulic chamber in which the combustible fluid is located.
- the frame is preferably formed on the rear side of the door operator, in particular the housing.
- the piston plate can be located on the back of the frame.
- the invention includes a second arrangement with a door operator and the described fire protection attachment device, wherein the door operator can be attached directly to the frame, in particular can be screwed on.
- the frame of the fire protection fastening device in turn, can preferably be fastened directly to the mounting surface, in particular screwed on.
- the invention also includes a third arrangement with a door operator and the fire protection fastening device described, as well as an additional mounting plate.
- the mounting plate is to be arranged between the fire protection fastening device and the door operator.
- the mounting plate is attached to the frame of the fire protection attachment device, in particular screwed on.
- the frame of the fire protection fastening device must in turn be screwed to the mounting surface.
- the door operator can be connected in the usual way to the front of the mounting plate, in particular screwed. During thermal activation, the mounting plate is pushed away from the mounting surface. The door actuator is released together with the mounting plate.

Description
Die Erfindung betrifft eine Brandschutzbefestigungseinrichtung zur Befestigung eines Türbetätigers. Des Weiteren zeigt die Erfindung Anordnungen umfassend einen Türbetätiger samt Brandschutzbefestigungseinrichtung.The invention relates to a fire protection fastening device for fastening a door operator. Furthermore, the invention shows arrangements comprising a door operator together with a fire protection fastening device.
Türbetätiger werden dazu verwendet, Türen zu schließen und/oder zu öffnen. Als Türbetätiger werden insbesondere Türschließer und Türantriebe bezeichnet. Beim Türschließer wird im Regelfall durch die manuelle Öffnungsbewegung ein Federspeicher geladen. Die dabei gespeicherte Energie wird zum Schließen der Tür genutzt. Beim Türantrieb kann beispielsweise mittels Elektromechanik oder Hydraulik die Tür selbständig geöffnet und/oder geschlossen werden.Door operators are used to close and/or open doors. In particular, door closers and door drives are referred to as door actuators. In the case of door closers, a spring accumulator is usually charged by the manual opening movement. The energy stored in this way is used to close the door. With the door drive, for example, the door can be opened and/or closed independently by means of electromechanics or hydraulics.
Türbetätiger werden üblicherweise an einer Montagefläche, also auf dem Türblatt oder der Zarge bzw. der Wand befestigt. Insbesondere bei Brandschutztüren ist zu beachten, dass in den Türbetätigern oftmals brennbare Fluide, beispielsweise Hydrauliköle, zur Anwendung kommen. Durch geeignete Maßnahmen ist möglichst zu vermeiden, dass sich das Fluid im Türbetätiger im Brandfall zu stark erhitzt und gegebenenfalls entzündet.Door operators are usually attached to a mounting surface, ie on the door leaf or the frame or the wall. In the case of fire protection doors in particular, it should be noted that flammable fluids, such as hydraulic oils, are often used in the door actuators. Appropriate measures should be taken to prevent the fluid in the door actuator from heating up too much in the event of a fire and potentially igniting it.
Es ist Aufgabe vorliegender Erfindung, eine Brandschutzbefestigungseinrichtung für einen Türbetätiger anzugeben, die eine betriebssichere Befestigung des Türbetätigers ermöglicht und gleichzeitig sicherheitsrelevante Anforderungen, insbesondere für den Brandfall, erfüllt.It is the object of the present invention to specify a fire protection fastening device for a door operator which enables the door operator to be fastened in a reliable manner and at the same time meets safety-related requirements, in particular in the event of a fire.
Die Lösung der Aufgabe erfolgt durch die Merkmale des unabhängigen Anspruchs. Die abhängigen Ansprüche haben vorteilhafte Ausgestaltungen der Erfindung zum Gegenstand.The object is solved by the features of the independent claim. The dependent claims relate to advantageous configurations of the invention.
Die Erfindung beschreibt eine Brandschutzbefestigungseinrichtung zur Befestigung eines Türbetätigers. Wie eingangs erwähnt, handelt es sich bei dem Türbetätiger um einen Türschließer oder einen Türantrieb. Der Türbetätiger ist an einer Montagefläche zu befestigen. Diese Montagefläche ist insbesondere durch eine Tür, Zarge oder Wand gebildet.The invention describes a fire protection fastening device for fastening a door operator. As mentioned at the beginning, the door operator is a door closer or a door drive. The door operator must be attached to a mounting surface. This mounting surface is formed in particular by a door, frame or wall.
Die Brandschutzbefestigungseinrichtung umfasst einen Rahmen. Gemäß einer Ausgestaltung der Erfindung ist der Rahmen zur Anordnung zwischen dem Türbetätiger und der Montagefläche ausgebildet. Wenn auf eine separate Montageplatte verzichtet wird, liegt dabei der Türbetätiger unmittelbar an der Vorderseite des Rahmens an. Die Rückseite des Rahmens ist der Montagefläche zugewandt; liegt insbesondere direkt an der Montagefläche an. Wie noch im Detail beschrieben wird, kann zwischen dem Rahmen der Brandschutzbefestigungseinrichtung und dem Türbetätiger eine Montageplatte verwendet werden. Insbesondere wird dabei die Montageplatte mit dem Rahmen der Brandschutzbefestigungseinrichtung verschraubt und der Türbetätiger an der Montageplatte befestigt.The fire protection fastening device includes a frame. According to one embodiment of the invention, the frame is designed to be arranged between the door operator and the mounting surface. If there is no separate mounting plate, the door operator lies directly on the front of the frame. The back of the frame faces the mounting surface; is particularly close to the mounting surface. As will be described in detail below, a mounting plate can be used between the frame of the fire protection attachment and the door operator. In particular, the mounting plate is screwed to the frame of the fire protection fastening device and the door operator is fastened to the mounting plate.
In einer alternativen Ausgestaltung ist vorgesehen, dass der Rahmen der Brandschutzbefestigungseinrichtung integraler Bestandteil des Türbetätigers ist. Auch diese Ausgestaltung wird noch im Detail erläutert.In an alternative embodiment, it is provided that the frame of the fire protection fastening device is an integral part of the door operator. This configuration will also be explained in detail.
Zur Beschreibung der Erfindung ist eine Montageachse definiert. Die Montageachse steht senkrecht zum Rahmen, insbesondere senkrecht zur Rückseite des Rahmens. Ferner steht die Montageachse senkrecht zur Montagefläche. Die Montageachse steht beispielsweise parallel zu den Schrauben, die zum Anschrauben des Rahmens an der Montagefläche verwendet werden. Gemäß einer alternativen Definition steht die Montageachse senkrecht zur Abtriebsachse des Türbetätigers. Über diese Abtriebsachse ist der Türbetätiger, beispielsweise über ein Gestänge, mit der Tür bzw. Wand zu verbinden.A mounting axis is defined to describe the invention. The mounting axis is perpendicular to the frame, particularly perpendicular to the back of the frame. Furthermore, the mounting axis is perpendicular to the mounting surface. For example, the mounting axis is parallel to the screws used to bolt the frame to the mounting surface. According to an alternative definition, the mounting axis is perpendicular to the output axis of the door operator. The door operator can be connected to the door or wall via this output shaft, for example via a linkage.
In dem Rahmen der Brandschutzbefestigungseinrichtung ist zumindest eine Reaktionskammer ausgebildet. In bevorzugter Ausgestaltung weist der Rahmen mehrere Reaktionskammern auf. Insbesondere sind in dem Rahmen zwei, drei, vier, fünf, sechs, sieben oder acht Reaktionskammern vorgesehen. Der Einfachheit halber wird die Erfindung meist anhand einer Reaktionskammer beschrieben, wobei stets vorgesehen ist, dass die mehreren Reaktionskammern gleich ausgebildet sind. Allerdings können sich die Reaktionskammern in ihrer Größe unterscheiden, so dass, je nach geometrischer Ausgestaltung der Brandschutzbefestigungseinrichtung, möglichst viele Reaktionskammern mit möglichst großer Fläche verwendet werden können.At least one reaction chamber is formed in the frame of the fire protection fastening device. In a preferred embodiment, the frame has several reaction chambers. In particular, two, three, four, five, six, seven or eight reaction chambers are provided in the frame. For the sake of simplicity, the invention is usually described using a reaction chamber, it always being provided that the several reaction chambers are of identical design. However, the reaction chambers can differ in their size, so that, depending on the geometric design of the fire protection fastening device, as many reaction chambers as possible with the largest possible area can be used.
Die jeweilige Reaktionskammer ist voll umfänglich durch den Rahmen begrenzt. Die Reaktionskammer erstreckt sich mit ihrer Tiefe parallel zur Montageachse. Dementsprechend ist auch der Umfang der Reaktionskammer bezüglich einer zur Montageachse parallelen Achse definiert. Die Reaktionskammer ist an der Rückseite und/oder der Vorderseite des Rahmens offen. Wenn die Reaktionskammer auf beiden Seiten, d. h. auf der Vorderseite und auf der Rückseite, offen ist, handelt es sich um eine Durchgangsaussparung in dem Rahmen. Wenn die Reaktionskammer nur auf einer der beiden Seiten offen ist, handelt es sich insbesondere um eine im Rahmen ausgebildete Tasche.The respective reaction chamber is fully delimited by the frame. The depth of the reaction chamber extends parallel to the mounting axis. Accordingly, the circumference of the reaction chamber is also defined with respect to an axis parallel to the assembly axis. The reaction chamber is open at the rear and/or the front of the frame. If the reaction chamber on both sides, i. H. on the front and on the back, is open, it is a through hole in the frame. If the reaction chamber is only open on one of the two sides, it is in particular a pocket formed in the frame.
In jeder Reaktionskammer ist ein Antriebselement angeordnet. Das Antriebselement ist aus thermisch intumeszierendem Material gefertigt. Das Antriebselement ist dazu ausgebildet, bei thermischer Aktivierung, also bei entsprechender Erwärmung, den Türbetätiger von der Montagefläche wegzudrücken. Insbesondere ist vorgesehen, dass das thermisch aktivierbare Material des Antriebselementes in einem Temperaturbereich von 90°C bis 200°C aktivierbar ist.A drive element is arranged in each reaction chamber. The drive element is made of thermally intumescent material. The drive element is designed to push the door actuator away from the mounting surface when it is thermally activated, that is to say when it is heated accordingly. In particular, it is provided that the thermally activatable material of the drive element can be activated in a temperature range of 90°C to 200°C.
Bei dem Antriebselement handelt es sich insbesondere um ein flächiges plattenförmiges Material, das beliebig zuschneidbar ist. Da dieses Material in bestimmten Dicken verfügbar ist, ist bevorzugt vorgesehen, dass zur Bildung des Antriebselementes mehrere Schichten übereinandergelegt werden. Die mehreren Schichten bilden dann zusammen ein Antriebselement.The drive element is in particular a flat, plate-shaped material that can be cut to any size. Since this material is available in certain thicknesses, it is preferably provided that several layers are superimposed to form the drive element. The several layers then together form a drive element.
Durch Aktivierung des thermisch intumeszierenden Materials erhöht sich das Volumen dieses Materials, beispielsweise durch Aufschäumen. Dadurch, dass das Antriebselement in der Reaktionskammer angeordnet ist und dadurch, dass die Reaktionskammer voll umfänglich durch den Rahmen begrenzt ist, dehnt sich das Antriebselement lediglich in einer zur Montageachse parallelen Richtung aus. Die Ausdehnung des Antriebselementes in einer dazu senkrechten Richtung ist durch die vollumfängliche Begrenzung durch den Rahmen blockiert.By activating the thermally intumescent material, the volume of this material increases, for example by foaming. Due to the fact that the drive element is arranged in the reaction chamber and due to the fact that the reaction chamber is completely delimited by the frame, the drive element only expands in a direction parallel to the mounting axis. The expansion of the drive element in a direction perpendicular thereto is blocked by the full-circumferential limitation by the frame.
Wie bereits beschrieben, kann der Rahmen als eigenständiges Bauteil zwischen Türbetätiger und Montagefläche angeordnet werden. Zwischen Rahmen und Türbetätiger kann sich dabei gegebenenfalls eine Montageplatte befinden. In dieser Anordnung des Rahmens kann die Reaktionskammer sowohl an der Vorderseite als auch an der Rückseite offen sein. Entscheidend ist, dass sich bei thermischer Aktivierung das Antriebselement in der zur Montageachse parallelen Richtung ausdehnt, wodurch ein Wegdrücken des Türbetätigers von der Montagefläche erfolgt. Ob dabei der Rahmen mit weggedrückt wird oder montageflächenseitig verbleibt ist für die grundsätzliche Funktion der Erfindung nicht relevant.As already described, the frame can be arranged as an independent component between the door operator and the mounting surface. If necessary, a mounting plate can be located between the frame and the door operator. In this arrangement of the frame, the reaction chamber can be open at both the front and the back. What is decisive is that, when thermally activated, the drive element expands in the direction parallel to the mounting axis, as a result of which the door actuator is pushed away from the mounting surface. Whether the frame is pushed away with it or remains on the mounting surface side is not relevant for the basic function of the invention.
Bei der Ausgestaltung wonach der Rahmen integraler Bestandteil des Türbetätigers ist, ist insbesondere vorgesehen, dass die Reaktionskammer an der Rückseite offen ist, um so den Türbetätiger samt integralem Rahmen von der Montagefläche wegzudrücken.In the embodiment according to which the frame is an integral part of the door operator, it is provided in particular that the reaction chamber is open at the rear in order to push the door operator together with the integral frame away from the mounting surface.
Bei der thermischen Aktivierung des Antriebselements bzw. der mehreren Antriebselemente in den einzelnen Reaktionskammern kommt es zum Wegdrücken des Türbetätigers von der Montagefläche, wobei beispielsweise die Außengewinde auf den Schrauben oder die zugehörigen Innengewinde brechen. Dadurch löst sich der Türbetätiger von der Montagefläche, also von der Türe, Zarge oder Wand. Dabei wird insbesondere davon ausgegangen, dass sich der Türbetätiger an der brandabgewandten Seite der Tür befindet. Durch das Ablösen des Türbetätigers von seiner Montagefläche wird vermieden, dass sich der Türbetätiger zu stark erhitzt, wodurch eine Entzündung des Fluids im Türbetätiger vermieden wird.When the drive element or the several drive elements in the individual reaction chambers are thermally activated, the door actuator is pushed away from the mounting surface, with the external threads on the screws or the associated internal threads breaking, for example. This releases the door operator from the mounting surface, i.e. from the door, frame or wall. In particular, it is assumed that the door operator is on the side of the door away from the fire. Detaching the door operator from its mounting surface avoids overheating the door operator, thereby avoiding ignition of the fluid in the door operator.
In bevorzugter Ausführung ist vorgesehen, dass die Brandschutzbefestigungseinrichtung eine in der Reaktionskammer angeordnete Kolbenplatte aufweist. Insbesondere ist die Kolbenplatte derart in der Reaktionskammer angeordnet, dass die Montageachse orthogonal zur Kolbenplatte steht. Bei Verwendung mehrerer Reaktionskammern befindet sich in jeder Reaktionskammer ein Antriebselement und jeweils eine bevorzugt zu verwendende Kolbenplatte.In a preferred embodiment, it is provided that the fire protection fastening device has a piston plate arranged in the reaction chamber. In particular, the piston plate is arranged in the reaction chamber in such a way that the mounting axis is orthogonal to the piston plate. If several reaction chambers are used, there is a drive element in each reaction chamber and a piston plate that is to be used preferably.
Die Kolbenplatte ist insbesondere aus einem steifen Material gebildet und dient dazu, bei thermischer Aktivierung des Antriebselements durch das Antriebselement verschoben zu werden. Dabei ist insbesondere vorgesehen, dass die Kolbenplatte in der Reaktionskammer geführt ist. Die Verschiebungsrichtung ist insbesondere parallel zur Montageachse. Der Spalt zwischen Kolbenplatte und Reaktionskammer ist vorzugsweise möglichst klein zu halten, so dass das intumeszierende Material des Antriebselementes nicht durch den Spalt an der Kolbenplatte vorbeiquillt. Während der Aktivierung, also bei der Ausdehnung des Antriebselementes, können sowohl das Antriebselement als auch die Kolbenplatte aus der Reaktionskammer austreten.In particular, the piston plate is formed from a rigid material and serves to be displaced by the drive element when the drive element is thermally activated. It is provided in particular that the piston plate is guided in the reaction chamber. The direction of displacement is in particular parallel to the assembly axis. The gap between the piston plate and the reaction chamber should preferably be kept as small as possible so that the intumescent material of the drive element does not swell past the piston plate through the gap. During activation, ie during expansion of the drive element, both the drive element and the piston plate can exit the reaction chamber.
Die Kolbenplatte kann grundsätzlich auf der Vorderseite oder der Rückseite des Antriebselementes angeordnet werden. Ferner ist es auch möglich, auf beiden Seiten des Antriebselementes jeweils eine Kolbenplatte anzuordnen. Dementsprechend sind dann pro Reaktionskammer zwei Kolbenplatten vorgesehen.In principle, the piston plate can be arranged on the front or the rear of the drive element. Furthermore, it is also possible to arrange a piston plate on both sides of the drive element. Accordingly, two piston plates are then provided per reaction chamber.
Die Kolbenplatten können auch als Druckverteilplatten oder Druckmodulatorplatten bezeichnet werden, da sie dafür sorgen, dass der vom Antriebselement aufgebrachte Druck möglichst über eine große Fläche übertragen wird. Ferner sorgen sie dafür, dass das Antriebselement bei einer thermischen Aktivierung nicht in Hohlräumen, beispielsweise der zerklüfteten Rückseite eines Türbetätigers, nutzlos verteilt wird.The piston plates can also be referred to as pressure distribution plates or pressure modulator plates, since they ensure that the pressure applied by the drive element is transmitted over as large an area as possible. They also ensure that the drive element is not uselessly distributed in cavities, for example the jagged rear side of a door operator, in the event of thermal activation.
Vorzugsweise ist vorgesehen, dass die Kolbenplatte aus Metall, beispielsweise aus Aluminium, gefertigt ist. Dadurch ist eine steife, leichtbauende und einfach zu fertigende Kolbenplatte gegeben.It is preferably provided that the piston plate is made of metal, for example aluminum. This results in a stiff, lightweight piston plate that is easy to manufacture.
Allerdings ist auch zu berücksichtigen, dass in den meisten Anwendungsfällen eine thermisch isolierende Ausgestaltung der Brandschutzbefestigungseinrichtung von Vorteil ist. Grundsätzlich soll der Wärmeeintrag von der Montagefläche in das Antriebselement möglichst widerstandsfrei erfolgen. Jegliche weitere Wärmeleitung, insbesondere in Richtung des Türbetätigers sollte jedoch nach Möglichkeit unterbunden werden. Deshalb ist bevorzugt vorgesehen, dass eine Kolbenplatte, die zwischen dem Antriebselement und dem Türbetätiger angeordnet ist, aus nicht-metallischem, thermisch isolierendem Material gefertigt ist. Alternativ hierzu kann die Kolbenplatte auch mehrschichtig sein, wobei zumindest eine Schicht aus nicht-metallischem, thermisch isolierendem Material gefertigt ist. Ferner kann vorgesehen sein, dass eine Kolbenplatte, die zwischen dem Antriebselement und der Montagefläche angeordnet ist, aus metallischem, thermisch leitendem Material gefertigt ist. Hierdurch wird erreicht, dass ein Wärmeübertrag von der Montagefläche in das Antriebselement zügig erfolgt, um eine frühzeitige Volumenvergrößerung des intumeszierenden Materials sicherzustellen. Somit kann vorgesehen sein, dass das Antriebselement von zwei verschiedenen Kolbenplatten, insbesondere von zwei Kolbenplatten mit unterschiedlicher thermischer Leitfähigkeit, eingefasst ist.However, it must also be taken into account that in most applications a thermally insulating design of the fire protection fastening device is advantageous. In principle, the heat input from the mounting surface into the drive element should be as resistance-free as possible. However, any further heat conduction, especially in the direction of the door operator, should be prevented if possible will. It is therefore preferably provided that a piston plate, which is arranged between the drive element and the door operator, is made of non-metallic, thermally insulating material. As an alternative to this, the piston plate can also be multi-layered, with at least one layer being made of non-metallic, thermally insulating material. Furthermore, it can be provided that a piston plate, which is arranged between the drive element and the mounting surface, is made of metallic, thermally conductive material. This ensures that heat is transferred quickly from the mounting surface to the drive element in order to ensure an early increase in volume of the intumescent material. It can thus be provided that the drive element is surrounded by two different piston plates, in particular by two piston plates with different thermal conductivity.
Insbesondere bei der ausschließlichen Fertigung der Kolbenplatte aus dem thermisch isolierenden Material ist darauf zu achten, dass ein entsprechend stabiles Material zur Gestaltung einer steifen Kolbenplatte verwendet wird. Hierzu eignen sich entsprechende Kunststoffe.In particular, when the piston plate is exclusively made from the thermally insulating material, care must be taken to ensure that a correspondingly stable material is used to design a stiff piston plate. Appropriate plastics are suitable for this.
Zusätzlich oder alternativ zur Verwendung des thermisch isolierenden Materials in der Kolbenplatte ist bevorzugt vorgesehen, dass auf zumindest einer Seite der Kolbenplatte zumindest eine Isolationsplatte aufgelegt ist, die aus nicht-metallischem, thermisch isolierendem Material gefertigt ist. Vorzugsweise ist die Isolationsplatte aus einem Faserverbundwerkstoff gefertigt.In addition or as an alternative to using the thermally insulating material in the piston plate, it is preferably provided that at least one insulating plate made of non-metallic, thermally insulating material is placed on at least one side of the piston plate. The insulation panel is preferably made of a fiber composite material.
Wenn die Isolationsplatte zwischen Kolbenplatte und Antriebselement eingelegt wird, befindet sie sich insbesondere in der Reaktionskammer. Wenn die Isolationsplatte auf der dem Antriebselement abgewandten Seite der Kolbenplatte aufgelegt wird, kann sie sich auch außerhalb der Reaktionskammer befinden.When the insulation plate is inserted between the piston plate and the drive element, it is located in particular in the reaction chamber. If the insulating plate is placed on the side of the piston plate facing away from the drive element, it can also be located outside the reaction chamber.
Die einzelne Reaktionskammer weist senkrecht zur Montageachse eine Querschnittsfläche auf. Diese Querschnittfläche der Reaktionskammer ist insbesondere rechteckig, da sich bei dieser geometrischen Ausgestaltung möglichst viele Reaktionskammern bzw. Reaktionskammern mit großer Fläche über den Rahmen verteilen lassen. Allerdings sind auch andere Querschnittsflächen möglich. Bevorzugt ist jedoch vorgesehen, dass das Antriebselement und/oder die Kolbenplatte und/oder die Isolationsplatte sich über die gesamte Querschnittsfläche erstreckt / erstrecken.The single reaction chamber has a cross-sectional area perpendicular to the mounting axis. This cross-sectional area of the reaction chamber is in particular rectangular, since as many reaction chambers or reaction chambers with a large area as possible can be distributed over the frame with this geometric configuration. However, other cross-sectional areas are also possible. However, it is preferably provided that the drive element and/or the piston plate and/or the insulating plate extends/extend over the entire cross-sectional area.
Die Reaktionskammer ist vorzugsweise auf beiden Seiten, d. h. auf der Vorderseite und auf der Rückseite, offen. Insbesondere ist die Reaktionskammer auf beiden Seiten jeweils über den gesamten Querschnitt offen. Die offene Rückseite der Reaktionskammer hat zum Vorteil, dass hier das Antriebselement unmittelbar in direkter Berührung mit der Montagefläche stehen kann. Dadurch erfolgt eine möglichst schnelle und ausreichende Erwärmung des Antriebselements im Brandfall. Über die offene Vorderseite kann sich das Antriebselement in Richtung des Türbetätigers ausbreiten bzw. die Kolbenplatte in Richtung des Türbetätigers schieben.The reaction chamber is preferably on both sides, i. H. on the front and on the back, open. In particular, the reaction chamber is open on both sides over the entire cross section. The open rear of the reaction chamber has the advantage that the drive element can be in direct contact with the mounting surface. As a result, the drive element is heated as quickly and adequately as possible in the event of a fire. The drive element can spread out in the direction of the door operator or push the piston plate in the direction of the door operator via the open front side.
Die Brandschutzbefestigungseinrichtung ist möglichst flach ausgebildet und ist möglichst so gestaltet, dass sie unauffällig zwischen Türbetätiger und Montagefläche angeordnet werden kann. Eine Tiefe der einzelnen Reaktionskammern ist senkrecht zur Montageachse definiert. Diese Tiefe der Reaktionskammer liegt vorzugsweise zwischen 1 mm und 30 mm, insbesondere zwischen 5 mm und 20 mm. Dadurch ist ausreichend Bauraum gegeben, um das Antriebselement, gegebenenfalls auch die Kolbenplatte, in der Reaktionskammer anzuordnen.The fire protection fastening device is designed as flat as possible and is designed as far as possible in such a way that it can be arranged inconspicuously between the door operator and the mounting surface. A depth of each reaction chamber is defined perpendicular to the mounting axis. This depth of the reaction chamber is preferably between 1 mm and 30 mm, in particular between 5 mm and 20 mm. This provides sufficient installation space to arrange the drive element, possibly also the piston plate, in the reaction chamber.
Senkrecht zur Montageachse ist die Querschnittsfläche der einzelnen Reaktionskammern definiert. Diese liegt vorzugsweise zwischen 400 mm2 und 50.000 mm2; vorzugsweise zwischen 900 mm2 und 10.000 mm2.The cross-sectional area of the individual reaction chambers is defined perpendicular to the assembly axis. This is preferably between 400 mm 2 and 50,000 mm 2 ; preferably between 900 mm 2 and 10,000 mm 2 .
Bei Verwendung mehrerer Reaktionskammern ist auch die Summe aller Querschnittsflächen von Interesse, da durch eine möglichst große gesamte Querschnittfläche entsprechend viel Kraft zum Wegdrücken des Türbetätigers aufgebracht werden kann. So beträgt die Summe aller Querschnittflächen aller Reaktionskammern vorzugsweise zumindest 2.500 mm2, insbesondere zumindest 5.000 mm2.If several reaction chambers are used, the sum of all cross-sectional areas is also of interest, since a correspondingly large total cross-sectional area can be used to push the door actuator away. The sum of all cross-sectional areas of all reaction chambers is preferably at least 2,500 mm 2 , in particular at least 5,000 mm 2 .
Gemäß einer bereits beschriebenen Ausgestaltung ist der Rahmen nicht integraler Bestandteil des Türbetätigers, sondern wird zwischen Montagefläche und Türbetätiger bzw. Montageplatte angeordnet. Dabei ist insbesondere vorgesehen, dass der Rahmen zum Anschrauben an der Montagefläche erste Befestigungspunkte aufweist. Ferner sind in dem Rahmen zweite Befestigungspunkte ausgebildet, an denen der Türbetätiger oder eine etwaige Montageplatte am Rahmen befestigt werden können. Bei den Befestigungspunkten handelt es sich insbesondere um Durchgangslöcher. Insbesondere bei den zweiten Befestigungspunkten weisen die Durchgangslöcher vorzugsweise ein Innengewinde auf. Alternativ zu der Ausgestaltung als Löcher können die Befestigungspunkte beispielsweise auch durch Gewindestangen gebildet sein.According to an embodiment already described, the frame is not an integral part of the door operator, but is arranged between the mounting surface and the door operator or mounting plate. It is provided in particular that the frame has first attachment points for screwing to the mounting surface. Furthermore, second attachment points are formed in the frame, at which the door operator or any mounting plate can be attached to the frame. The attachment points are, in particular, through-holes. In particular at the second fastening points, the through-holes preferably have an internal thread. As an alternative to the design as holes, the fastening points can also be formed by threaded rods, for example.
Für die hier beschriebene Bemaßung der Befestigungspunkte sind jeweils deren Mitten, also beispielsweise die Lochmitten relevant.For the dimensioning of the fastening points described here, their centers are relevant, for example the center of the hole.
Jeweils zwei zueinander nächstliegende erste und zweite Befestigungspunkte bilden vorzugsweise ein Paar. Beispielsweise sind auf der rechten Seite des Rahmens zwei erste und zwei zweite Befestigungspunkte vorgesehen. Entsprechend sind beispielsweise auf der linken Seite des Rahmens zwei erste und zwei zweite Befestigungspunkte vorgesehen. Dadurch gibt es auf beiden Seiten des Rahmens jeweils zwei Paare.In each case two first and second attachment points which are closest to one another preferably form a pair. For example, two first and two second attachment points are provided on the right side of the frame. Accordingly, for example, on two first and two second attachment points are provided on the left side of the frame. This means there are two pairs on each side of the frame.
Um eine möglichst direkte Krafteinleitung beim Wegdrücken des Türbetätigers auf die Befestigungspunkte zu erreichen, ist vorzugsweise vorgesehen, dass der Abstand der Befestigungspunkte eines Paares möglichst klein ist. Insbesondere ist der Abstand zwischen erstem Befestigungspunkt und zweitem Befestigungspunkt des jeweiligen Paares höchstens das 5-fache, vorzugsweise höchstens das 4-fache, der Dicke des Rahmens. Die Dicke des Rahmens ist dabei parallel zur Montageachse definiert. Vorzugsweise ist dabei der Rahmen an seinem dicksten Punkt ausschlaggebend. Alternativ ist jeweils die gemittelte Dicke des Rahmens im Bereich zwischen den Befestigungspunkten eines Paares ausschlaggebend. Ist der Abstand der Befestigungspunkte eines Paares zu groß kann es dazu kommen, dass sich lediglich der Rahmen verformt, ohne dass der Türbetätiger sich von dem Rahmen löst.In order to achieve the most direct possible introduction of force to the attachment points when the door operator is pushed away, it is preferably provided that the distance between the attachment points of a pair is as small as possible. In particular, the distance between the first attachment point and the second attachment point of the respective pair is at most 5 times, preferably at most 4 times, the thickness of the frame. The thickness of the frame is defined parallel to the mounting axis. Preferably the frame at its thickest point is decisive. Alternatively, the average thickness of the frame in the area between the attachment points of a pair is decisive. If the distance between the attachment points of a pair is too great, it can happen that only the frame deforms without the door operator detaching from the frame.
