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 in particular a door closer or a door drive.
- Fire protection fastening device designed in particular for fastening a door actuator which generates force to move a door, in particular a door closer or door drive.
- the door operator must be attached to a mounting surface using the fire protection attachment device described here.
- This mounting surface is formed in particular by a door, frame or wall.
- the door is in particular the door leaf.
- the door operator is mounted by means of the fire protection fastening device in particular on the side of the door facing away from the fire.
- the fire protection fastening device is therefore designed in such a way that it detaches the door operator from its mounting surface, so that the door operator can in particular fall to the ground. This prevents the door operator from heating up too much and possibly igniting.
- the fire protection fastening device comprises a retaining plate and a mounting plate.
- the retaining plate and the mounting plate are connected to each other and to each other.
- the retaining plate is designed for attachment to the mounting surface, ie in particular the door, frame or wall.
- a mounting axis is defined perpendicularly to the retaining plate or perpendicularly to the mounting surface.
- the back of the retaining plate is designed in particular to rest directly against the mounting surface.
- the mounting axis is parallel to the screws used to screw the mounting plate to the mounting surface.
- the mounting axis is perpendicular to the output axis of the door operator.
- the door operator can be connected to the door or frame or wall via this output shaft, for example via a slide rail or a scissor linkage.
- the mounting plate is designed in particular to accommodate the door operator.
- the mounting plate is designed to receive the door operator, it being provided in particular that the door operator is only connected to the mounting plate, but not directly to the retaining plate or the mounting surface.
- the fire protection fastening device has at least one closed reaction chamber.
- the at least one reaction chamber is located between the holding plate and the mounting plate.
- the reaction chamber is formed by the holding plate and/or the mounting plate.
- the reaction chamber is closed as long as the mounting plate and the holding plate are connected to one another.
- the reaction chamber has in particular two opposite floors, one floor being formed by a surface of the mounting plate and the other floor being formed by a surface of the holding plate. The two floors face each other and each in particular perpendicular to the mounting axis.
- Fire protection attachment device several of these closed reaction chambers.
- two, three, four, five, six, seven or eight of these reaction chambers are provided in the fire protection fastening device.
- 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.
- a drive element is arranged in each reaction chamber.
- the drive element is made of thermally intumescent material.
- the drive element is designed to increase its volume upon thermal activation, that is to say upon corresponding heating.
- the mounting plate together with the door actuator is pushed away from the retaining plate, essentially perpendicular to the mounting axis.
- the connection between the retaining plate and the mounting plate is designed so that it dissolves in the process, so that the Mounting plate can fall off the retaining plate.
- the retaining plate remains on the mounting surface and the mounting plate together with the door actuator is detached from the retaining plate.
- the use of the retaining plate has the advantage that this mechanism works independently of the configuration, in particular the stability, of the mounting surface.
- this mechanism works independently of the configuration, in particular the stability, of the mounting surface.
- it is taken into account that depending on the design, structure and material of the respective door, there may not be any support on the door side in relation to the swelling drive element, so that the mounting surface would yield and bend to the high pressures of the intumescent material. This would create gaps and outlet openings through which the intumescent material could escape uncontrolled—without using the holding plate according to the invention.
- the retaining plate has the advantage that the screw connection between the retaining plate and the mounting surface is irrelevant for detaching the door operator in the event of a fire, since the retaining plate remains on the mounting surface.
- This is particularly advantageous since the fire protection fastening device can be used for different mounting surfaces and insofar as the quality, in particular strength, of the screw connection between the retaining plate and the mounting surface does not have to be specified when constructing the fire protection fastening device.
- the thermally intumescent material of the drive element can be activated in a temperature range of 90°C to 200°C.
- the retaining plate is stiff but designed as thin as possible.
- the reaction chamber is only formed by a pocket in the mounting plate. This pocket in the mounting plate is closed by the overlying retaining plate.
- the respective reaction chamber is formed by a pocket in the holding plate. This pocket is closed by the mounting plate. It is also possible to form the individual reaction chamber by means of a pocket in the mounting plate and a pocket in the holding plate. These two pockets then have the same size, in particular in terms of their cross section, and together form the closed reaction chamber as long as the retaining plate and the mounting plate are in contact with one another.
- a depth is defined on the individual reaction chamber parallel to the mounting axis. If the reaction chamber is merely formed by a pocket in the mounting plate, then the reaction chamber is positioned with 100% of its depth in the mounting plate. As explained, the reaction chamber can also be at least partially formed by a pocket in the mounting plate, with preferably provision being made for the reaction chamber to be positioned with at least 50% of its depth, preferably with at least 75% of its depth, in the mounting plate.
- the holding plate can be made as thin and visually appealing as possible.
- the holding plate and the mounting plate rest directly against one another and thus touch one another.
- a contact surface is formed on the mounting plate and on the holding plate. When the two plates are in the connected state, these contact surfaces lie against one another. In particular, the contact surface extends all the way around each reaction chamber or each pocket, so that the individual reaction chamber is closed all the way around. In particular, the reaction chambers are also closed to one another and are not connected to one another.
- the holding plate and the mounting plate are connected to one another.
- At least one connecting element is preferably used for this purpose.
- several of these connecting elements are used.
- the connecting element is in particular a screw.
- the connecting element is designed in such a way that it only connects the holding plate and the mounting plate to one another, but would not include any other elements, such as the mounting surface or the door operator, in the connection.
- the connecting element is a countersunk screw whose head is sunk into the holding plate or the mounting plate.
- the retaining plate preferably has first fastening points, and preferably associated screws, for screwing to the mounting surface.
- These first attachment points are, in particular, through-holes. Particularly preferably, these are screw head receiving holes, for example countersunk holes for receiving a countersunk screw.
- the first fastening points can also be formed by threaded rods, for example. Only the holding plate is to be fastened to the mounting surface via the first fastening points, ie in particular the screws inserted into the first fastening points.
- the mounting plate is not included in this attachment. For this purpose it is provided in particular that the mounting plate has at least one recess. In particular, a recess is provided for each first attachment point.
- the respective first fastening point of the retaining plate is accessible via the recess.
- the recess is designed in such a way that it does not receive a screw head, so that a screw can be inserted through the recess until the screw head rests against the first attachment point, without connecting the mounting plate as well.
- the recess is in particular a correspondingly large through hole.
- the mounting plate also has attachment points for screwing on the door operator, which are referred to here as second attachment points.
- the second attachment points are, in particular, holes with an internal thread. Alternatively, these attachment points could be threaded rods, for example.
- the second fastening points are designed in such a way that the door operator can be fastened to the mounting plate, this fastening not involving any further elements, in particular not the retaining plate and not the mounting surface.
- the mounting plate is firmly connected to the door operator, for example, is an integral part of the housing of the door operator.
- the mounting plate cannot then be detached from the door operator without being destroyed.
- care must be taken to ensure that the first attachment points for attaching the retaining plate to the mounting surface, in particular to the Insertion of screws, must be accessible.
- the practicable solution in most cases is that the door operator is screwed to the mounting plate.
- the entire fire protection fastening device can first be fastened to the mounting surface, whereupon the door operator is fastened to the fire protection fastening device, ie the mounting plate, in the next step.
- the mounting plate is preferably in one piece, in particular made of metal.
- the retaining plate is preferably in one piece, in particular made of metal. This results in simple production and a non-burning and stable design of these plates.
- the holding plate and the mounting plate are designed to be as large as possible in their dimension extending perpendicularly to the mounting axis. As a result, these two plates can rest against one another over as large an area as possible and the corresponding attachment points can be distributed over as large an area as possible. Furthermore, the result is a uniform and attractive visual design.
- the retaining plate extends perpendicularly to the assembly axis over a first cross-sectional area and the mounting plate extends perpendicularly to the assembly axis over a second cross-sectional area.
- a ratio of the first cross-sectional area to the second cross-sectional area is between 0.7 and 1.3, preferably between 0.8 and 0.9, particularly preferably between 0.9 and 1.1.
- a thickness of the holding plate at its thickest point is defined parallel to the assembly axis.
- This thickness of the holding plate is preferably between 1 mm and 20 mm, particularly preferably between 2 mm and 10 mm.
- a thickness of the mounting plate at its thickest point is defined parallel to the mounting axis.
- the thickness of the mounting plate is preferably between 1 mm and 30 mm, preferably between 5 mm and 20 mm.
- the drive element or the intumescent material is, in particular, a flat, plate-shaped material that can be cut to any desired size.
- only one layer of this plate-shaped material is inserted per reaction chamber.
- the drive element preferably extends over the entire cross-sectional area of the reaction chamber defined perpendicular to the assembly axis. As a result, the entire reaction chamber is filled with the drive element and as much of the intumescent material as possible is available.
- the single reaction chamber has a cross-sectional area perpendicular to the mounting axis.
- This cross-sectional area of the reaction chamber is preferably rectangular since, with this geometric design, as many reaction chambers or reaction chambers with a large area as possible can be distributed over the fire protection fastening device. However, other cross-sectional areas are also possible.
- 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.
- the depth of each Reaction chambers is preferably between 1 mm and 15 mm, in particular between 2 mm and 10 mm.
- the cross-sectional area of the individual reaction chamber is defined perpendicularly 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 invention also includes an arrangement with a door operator and the fire protection attachment device described above.
- the door operator is designed to be arranged on the mounting plate, in particular to be screwed onto the mounting plate.
- the door operator is particularly preferably screwed to the mounting plate.
- the door operator is in particular a door closer or a door drive.
- the door operator has a housing, for example made of die-cast. In the housing there is in particular at least one hydraulic chamber in which the combustible fluid is located.
- the arrangement includes a panel that covers the door operator.
- the cladding is designed in particular for direct attachment to the mounting plate.
- the mounting plate has a form-fitting contour at least at one point, which is designed to receive the paneling in a form-fitting manner.
- the mounting plate and the cladding are designed in such a way that the cladding covers the mounting plate, so that the mounting plate is not visible from the outside, or at least not completely at its periphery. As a result, only the retaining plate, which is designed to be relatively thin, remains visible.
- the invention also includes a door assembly.
- the door assembly in turn includes the assembly just described as well as the mounting surface.
- the door arrangement includes the door, frame or wall that forms the mounting surface.
- the retaining plate is designed to be attached to the mounting surface.
- the holding plate is fastened to the mounting plate, preferably screwed on.
- the invention shows a
- Fire protection fastening device which can perform an effective disconnection function of the door operator, regardless of the structure of the mounting surface. This is achieved by dividing it into two functional levels, i.e. the holding plate and the mounting plate. In this way, in particular, a mounting plate that is to be used conventionally can be replaced.
- the assembly-side fastening is carried out using a very stiff retaining plate, which in itself ensures fastening to the mounting surface and at the same time represents a very robust support for the intumescent material.
- the retaining plate remains on the mounting surface even after the door actuator has been detached, but due to the choice of material, especially metal, it does not pose a risk of ignition.
- the connection between the two functional levels i.e.
- connection between the retaining plate and the mounting plate is provided by appropriately selected connecting elements that engage in precisely defined threads for a defined strength. On the one hand, this ensures that the operating forces are transferred from the door operator to the mounting surface, but at the same time it is also possible to safely detach the retaining plate and mounting plate in the event of a fire.
- a further advantage of the invention is that the mounting plate and retaining plate can be pre-assembled at the factory and a ready-to-install fire protection fastening device can thus be made available.

Titel: Brandschutzbefestigungseinrichtung zur Befestigung eines Türbetätigers Title: Fire protection fastening device for fastening a door operator
Beschreibung 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 benutzt, 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 selbstständig 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 Brandschutz befestigungseinrichtung für einen Türbetätiger anzugeben, die eine betriebssichere Befestigung des Türbetätigers ermöglicht und gleichzeitig
sicherheitsrelevante Anforderungen, insbesondere für den Brandfall, erfüllt. It is an object of the present invention to provide a fire protection attachment device for a door operator, which enables a reliable attachment of the door operator and at the same time safety-related requirements, especially 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 insbesondere um einen Türschließer oder einen Türantrieb. Somit ist die erfindungsgemäßeThe invention describes a fire protection fastening device for fastening a door operator. As mentioned at the outset, the door operator is in particular a door closer or a door drive. Thus, the inventive
Brandschutzbefestigungseinrichtung insbesondere zur Befestigung eines, eine Tür bewegende Kraft erzeugenden Türbetätigers, insbesondere Türschließer oder Türantrieb, ausgebildet. Fire protection fastening device designed in particular for fastening a door actuator which generates force to move a door, in particular a door closer or door drive.
Der Türbetätiger ist mittels der hier beschriebenen Brandschutzbefestigungseinrichtung an einer Montagefläche zu befestigen. Diese Montagefläche ist insbesondere durch eine Tür, Zarge oder Wand gebildet. Bei der Tür handelt es sich insbesondere um das Türblatt. Im Rahmen der Erfindung ist vorgesehen, dass der Türbetätiger mittels der Brandschutzbefestigungseinrichtung insbesondere an der brandabgewandten Seite der Tür montiert wird. Im Brandfall kann es durch die Tür hindurch zu einem Wärmeeintrag in die Brandschutzbefestigungseinrichtung und in den Türbetätiger kommen. Die Brandschutzbefestigungseinrichtung ist deshalb so ausgebildet, dass sie den Türbetätiger von seiner Montagefläche löst, so dass der Türbetätiger insbesondere zu Boden fallen kann. Dadurch wird vermieden, dass sich der Türbetätiger zu stark erhitzt und gegebenenfalls entzündet.
Insbesondere ist vorgesehen, dass die Brandschutz befestigungseinrichtung eine Halteplatte und eine Montageplatte umfasst. Die Halteplatte und die Montageplatte sind aneinander und miteinander verbunden. Die Halteplatte ist zur Befestigung an der Montagefläche, also insbesondere der Tür, Zarge oder Wand, ausgebildet. Senkrecht zu der Halteplatte bzw. senkrecht zu der Montagefläche ist eine Montageachse definiert. Die Rückseite der Halteplatte ist insbesondere dazu ausgebildet, direkt an der Montagefläche anzuliegen. Die Montageachse steht beispielsweise parallel zu den Schrauben, die zum Anschrauben der Halteplatte an der Montagefläche verwendet werden. Gemäß einer alternativen Definition, steht die Montageachse senkrecht zur Abtriebsachse des Türbetätigers. Über dies Abtriebsachse ist der Türbetätiger, beispielsweise über eine Gleitschiene oder ein Scherengestänge, mit der Tür oder Zarge bzw. Wand zu verbinden. The door operator must be attached to a mounting surface using the fire protection attachment device described here. This mounting surface is formed in particular by a door, frame or wall. The door is in particular the door leaf. In the context of the invention it is provided that the door operator is mounted by means of the fire protection fastening device in particular on the side of the door facing away from the fire. In the event of a fire, heat can enter the fire protection fastening device and the door operator through the door. The fire protection fastening device is therefore designed in such a way that it detaches the door operator from its mounting surface, so that the door operator can in particular fall to the ground. This prevents the door operator from heating up too much and possibly igniting. In particular, it is provided that the fire protection fastening device comprises a retaining plate and a mounting plate. The retaining plate and the mounting plate are connected to each other and to each other. The retaining plate is designed for attachment to the mounting surface, ie in particular the door, frame or wall. A mounting axis is defined perpendicularly to the retaining plate or perpendicularly to the mounting surface. The back of the retaining plate is designed in particular to rest directly against the mounting surface. For example, the mounting axis is parallel to the screws used to screw the mounting plate 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 frame or wall via this output shaft, for example via a slide rail or a scissor linkage.
Die Montageplatte ist insbesondere zur Aufnahme des Türbetätigers ausgebildet. Es ist insbesondere vorgesehen, dass die Montageplatte nur mit der Halteplatte, jedoch nicht direkt mit der Montagefläche verbunden ist/wird. Des Weiteren ist die Montageplatte dazu ausgebildet, den Türbetätiger aufzunehmen, wobei insbesondere vorgesehen ist, dass der Türbetätiger lediglich mit der Montageplatte, jedoch nicht direkt mit der Halteplatte oder der Montagefläche verbunden wird. Dadurch wird erreicht, dass durch ein Lösen von Halteplatte und Montageplatte der Türbetätiger samt Montageplatte von der Halteplatte abfällt. Die Halteplatte verbleibt dabei an der Montagefläche. The mounting plate is designed in particular to accommodate the door operator. In particular, provision is made for the mounting plate to be connected only to the holding plate, but not directly to the mounting surface. Furthermore, the mounting plate is designed to receive the door operator, it being provided in particular that the door operator is only connected to the mounting plate, but not directly to the retaining plate or the mounting surface. As a result, the door operator together with the mounting plate falls off the retaining plate when the retaining plate and mounting plate are released. The retaining plate remains on the mounting surface.
Des Weiteren ist insbesondere vorgesehen, dass die Brandschutzbefestigungseinrichtung zumindest eine geschlossene Reaktionskammer aufweist. Die zumindest eine Reaktionskammer befindet sich zwischen Halteplatte und Montageplatte. Insbesondere ist
die Reaktionskammer durch die Halteplatte und/oder die Montageplatte gebildet. Des Weiteren ist bevorzugt vorgesehen, dass die Reaktionskammer geschlossen ist, solange die Montageplatte und die Halteplatte miteinander verbunden sind. Hierzu weist die Reaktionskammer insbesondere zwei gegenüberliegende Böden auf, wobei der eine Boden durch eine Fläche der Montageplatte und der andere Boden durch eine Fläche der Halteplatte gebildet ist. Die beiden Böden stehen sich gegenüber und jeweils insbesondere senkrecht zur Montageachse. Furthermore, it is provided in particular that the fire protection fastening device has at least one closed reaction chamber. The at least one reaction chamber is located between the holding plate and the mounting plate. In particular is the reaction chamber is formed by the holding plate and/or the mounting plate. Furthermore, it is preferably provided that the reaction chamber is closed as long as the mounting plate and the holding plate are connected to one another. For this purpose, the reaction chamber has in particular two opposite floors, one floor being formed by a surface of the mounting plate and the other floor being formed by a surface of the holding plate. The two floors face each other and each in particular perpendicular to the mounting axis.
In bevorzugter Ausgestaltung weist dieIn a preferred embodiment, the
Brandschutzbefestigungseinrichtung mehrere dieser geschlossenen Reaktionskammern auf. Insbesondere sind in der Brandschutzbefestigungseinrichtung zwei, drei, vier, fünf, sechs, sieben oder acht dieser 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. Fire protection attachment device several of these closed reaction chambers. In particular, two, three, four, five, six, seven or eight of these reaction chambers are provided in the fire protection fastening device. 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.
Insbesondere ist vorgesehen, dass in jeder Reaktionskammer ein Antriebselement angeordnet ist. Das Antriebselement ist aus thermisch intumeszierendem Material gefertigt. Das Antriebselement ist dazu ausgebildet, bei thermischer Aktivierung, also bei entsprechender Erwärmung, sein Volumen zu vergrößern. Dadurch wird die Montageplatte samt Türbetätiger von der Halteplatte, im Wesentlichen senkrecht zur Montageachse, weggedrückt. Die Verbindung zwischen Halteplatte und Montageplatte ist so ausgestaltet, dass sie sich dabei löst, so dass die
Montageplatte von der Halteplatte abfallen kann. Die Halteplatte verbleibt dabei an der Montagefläche und die Montageplatte samt Türbetätiger löst sich von der Halteplatte. In particular, it is provided that a drive element is arranged in each reaction chamber. The drive element is made of thermally intumescent material. The drive element is designed to increase its volume upon thermal activation, that is to say upon corresponding heating. As a result, the mounting plate together with the door actuator is pushed away from the retaining plate, essentially perpendicular to the mounting axis. The connection between the retaining plate and the mounting plate is designed so that it dissolves in the process, so that the Mounting plate can fall off the retaining plate. The retaining plate remains on the mounting surface and the mounting plate together with the door actuator is detached from the retaining plate.
Die Verwendung der Halteplatte hat den Vorteil, dass dieser Mechanismus unabhängig von der Ausgestaltung, insbesondere Stabilität, der Montagefläche funktioniert. Insbesondere wird berücksichtigt, dass je nach Konstruktion, Struktur und Material der jeweiligen Tür, eine türseitige Abstützung gegenüber dem aufquellenden Antriebselement nicht gegeben sein kann, so dass die Montagefläche gegenüber den hohen Drücken des intumeszierenden Materials nachgeben und sich verbiegen würde. Dadurch würden Fugen und Austrittsöffnungen entstehen, durch die das intumeszierende Material - ohne Verwendung der erfindungsgemäßen Halteplatte - unkontrolliert entweichen könnte. The use of the retaining plate has the advantage that this mechanism works independently of the configuration, in particular the stability, of the mounting surface. In particular, it is taken into account that depending on the design, structure and material of the respective door, there may not be any support on the door side in relation to the swelling drive element, so that the mounting surface would yield and bend to the high pressures of the intumescent material. This would create gaps and outlet openings through which the intumescent material could escape uncontrolled—without using the holding plate according to the invention.
Des Weiteren hat die Halteplatte den Vorteil, dass die Verschraubung zwischen Halteplatte und Montagefläche für das Ablösen des Türbetätigers im Brandfall keine Rolle spielt, da die Halteplatte an der Montagefläche verbleibt. Dies ist insbesondere von Vorteil, da die Brandschutzbefestigungseinrichtung für unterschiedliche Montageflächen verwendet werden kann und insofern die Qualität, insbesondere Festigkeit, der Verschraubung zwischen Halteplatte und Montagefläche nicht bei der Konstruktion der Brandschutzbefestigungseinrichtung festgelegt werden muss. Furthermore, the retaining plate has the advantage that the screw connection between the retaining plate and the mounting surface is irrelevant for detaching the door operator in the event of a fire, since the retaining plate remains on the mounting surface. This is particularly advantageous since the fire protection fastening device can be used for different mounting surfaces and insofar as the quality, in particular strength, of the screw connection between the retaining plate and the mounting surface does not have to be specified when constructing the fire protection fastening device.
Insbesondere ist vorgesehen, dass das thermisch intumeszierende Material des Antriebselements in einem Temperaturbereich von 90°C bis 200°C aktivierbar ist.
Vorzugsweise ist vorgesehen, dass die einzelne Reaktionskammer durch eine zur Halteplatte offene Tasche in der Montageplatte und/oder durch eine zur Montageplatte offene Tasche in der Halteplatte gebildet ist. In bevorzugter Ausführung ist vorgesehen, dass die Halteplatte zwar steif, aber möglichst dünn ausgestaltet ist. Entsprechend wird die Reaktionskammer lediglich durch eine Tasche in der Montageplatte gebildet. Diese Tasche in der Montageplatte ist durch die aufliegende Halteplatte verschlossen. In particular, it is provided that the thermally intumescent material of the drive element can be activated in a temperature range of 90°C to 200°C. Provision is preferably made for the individual reaction chamber to be formed by a pocket in the mounting plate which is open towards the mounting plate and/or by a pocket in the mounting plate which is open towards the mounting plate. In a preferred embodiment, it is provided that the retaining plate is stiff but designed as thin as possible. Correspondingly, the reaction chamber is only formed by a pocket in the mounting plate. This pocket in the mounting plate is closed by the overlying retaining plate.
Es ist jedoch auch vorgesehen, dass die jeweilige Reaktionskammer durch eine Tasche in der Halteplatte gebildet ist. Diese Tasche wird durch die Montageplatte verschlossen. Genauso ist es möglich, die einzelne Reaktionskammer durch eine Tasche in der Montageplatte und eine Tasche in der Halteplatte zu bilden. Diese beiden Taschen sind dann insbesondere in ihrem Querschnitt gleich groß und bilden, solange die Halteplatte und die Montageplatte aneinander anliegen, zusammen die geschlossene Reaktionskammer. However, it is also provided that the respective reaction chamber is formed by a pocket in the holding plate. This pocket is closed by the mounting plate. It is also possible to form the individual reaction chamber by means of a pocket in the mounting plate and a pocket in the holding plate. These two pockets then have the same size, in particular in terms of their cross section, and together form the closed reaction chamber as long as the retaining plate and the mounting plate are in contact with one another.
An der einzelnen Reaktionskammer ist parallel zur Montageachse eine Tiefe definiert. Wenn die Reaktionskammer lediglich durch eine Tasche in der Montageplatte gebildet ist, so ist die Reaktionskammer mit 100% ihrer Tiefe in der Montageplatte positioniert. Wie erläutert, kann die Reaktionskammer zumindest teilweise auch durch eine Tasche in der Halteplatte gebildet sein, wobei vorzugsweise vorgesehen ist, dass die Reaktionskammer mit zumindest 50% ihrer Tiefe, vorzugsweise mit zumindest 75% ihrer Tiefe, in der Montageplatte positioniert ist. Dadurch kann die Halteplatte möglichst dünn und optisch ansprechend ausgestaltet werden.
Die Halteplatte und die Montageplatte liegen insbesondere direkt aneinander an und berühren sich somit. So ist insbesondere an der Montageplatte und an der Halteplatte jeweils eine Anlagefläche gebildet. Diese Anlageflächen liegen in verbundenem Zustand der beiden Platten aneinander an. Insbesondere erstreckt sich die Anlagefläche ringsum um jede Reaktionskammer bzw. jede Tasche, so dass die einzelne Reaktionskammer ringsum geschlossen ist. Insbesondere sind auch die Reaktionskammern untereinander geschlossen und nicht etwa miteinander verbunden. A depth is defined on the individual reaction chamber parallel to the mounting axis. If the reaction chamber is merely formed by a pocket in the mounting plate, then the reaction chamber is positioned with 100% of its depth in the mounting plate. As explained, the reaction chamber can also be at least partially formed by a pocket in the mounting plate, with preferably provision being made for the reaction chamber to be positioned with at least 50% of its depth, preferably with at least 75% of its depth, in the mounting plate. As a result, the holding plate can be made as thin and visually appealing as possible. In particular, the holding plate and the mounting plate rest directly against one another and thus touch one another. In particular, a contact surface is formed on the mounting plate and on the holding plate. When the two plates are in the connected state, these contact surfaces lie against one another. In particular, the contact surface extends all the way around each reaction chamber or each pocket, so that the individual reaction chamber is closed all the way around. In particular, the reaction chambers are also closed to one another and are not connected to one another.
Die Halteplatte und die Montageplatte sind, wie bereits beschrieben, miteinander verbunden. Hierzu wird vorzugsweise zumindest ein Verbindungselement verwendet. Insbesondere werden mehrere dieser Verbindungselemente verwendet. Bei dem Verbindungselement handelt es sich insbesondere um eine Schraube. Das Verbindungselement ist so ausgestaltet, dass es lediglich die Halteplatte und die Montageplatte miteinander verbindet, jedoch keine weiteren Elemente, wie etwa die Montagefläche oder den Türbetätiger, in die Verbindung mit einbeziehen würde. Insbesondere ist das Verbindungselement eine Senkkopfschraube, deren Kopf in die Halteplatte oder die Montageplatte versenkt ist. As already described, the holding plate and the mounting plate are connected to one another. At least one connecting element is preferably used for this purpose. In particular, several of these connecting elements are used. The connecting element is in particular a screw. The connecting element is designed in such a way that it only connects the holding plate and the mounting plate to one another, but would not include any other elements, such as the mounting surface or the door operator, in the connection. In particular, the connecting element is a countersunk screw whose head is sunk into the holding plate or the mounting plate.
Die Halteplatte weist vorzugsweise zum Anschrauben an der Montagefläche erste Befestigungspunkte, und vorzugsweise zugehörige Schrauben, auf. Bei diesen ersten Befestigungspunkten handelt es sich insbesondere um Durchgangslöcher. Besonders bevorzugt handelt es sich um schraubenkopfaufnehmende Löcher, beispielsweise gesenkte Löcher zur Aufnahme einer Senkkopfschraube. Alternativ zur Ausgestaltung als Löcher können die ersten Befestigungspunkte auch durch beispielsweise Gewindestangen gebildet sein.
Über die ersten Befestigungspunkte, also insbesondere die in die ersten Befestigungspunkte eingesetzten Schrauben, soll lediglich die Halteplatte an der Montagefläche befestigt werden. Die Montageplatte wird in diese Befestigung nicht mit einbezogen. Hierzu ist insbesondere vorgesehen, dass die Montageplatte zumindest eine Aussparung aufweist. Insbesondere ist pro erstem Befestigungspunkt eine Aussparung vorgesehen. Über die Aussparung ist der jeweilige erste Befestigungspunkt der Halteplatte zugänglich. Insbesondere ist die Aussparung so ausgebildet, dass sie nicht schraubenkopfaufnehmend ist, so dass eine Schraube durch die Aussparung hindurch soweit einführbar ist, bis der Schraubenkopf am ersten Befestigungspunkt anliegt, ohne dabei die Montageplatte mit zu verbinden. Bei der Aussparung handelt es sich insbesondere um ein entsprechend großes Durchgangsloch. The retaining plate preferably has first fastening points, and preferably associated screws, for screwing to the mounting surface. These first attachment points are, in particular, through-holes. Particularly preferably, these are screw head receiving holes, for example countersunk holes for receiving a countersunk screw. As an alternative to the design as holes, the first fastening points can also be formed by threaded rods, for example. Only the holding plate is to be fastened to the mounting surface via the first fastening points, ie in particular the screws inserted into the first fastening points. The mounting plate is not included in this attachment. For this purpose it is provided in particular that the mounting plate has at least one recess. In particular, a recess is provided for each first attachment point. The respective first fastening point of the retaining plate is accessible via the recess. In particular, the recess is designed in such a way that it does not receive a screw head, so that a screw can be inserted through the recess until the screw head rests against the first attachment point, without connecting the mounting plate as well. The recess is in particular a correspondingly large through hole.
Die Montageplatte weist zum Anschrauben des Türbetätigers ebenfalls Befestigungspunkte auf, die hier als zweite Befestigungspunkte bezeichnet werden. Bei den zweiten Befestigungspunkten handelt es sich insbesondere um Löcher mit Innengewinde. Alternativ könnten diese Befestigungspunkte beispielsweise Gewindestangen sein. Die zweiten Befestigungspunkte sind so ausgebildet, dass der Türbetätiger an der Montageplatte befestigt werden kann, wobei diese Befestigung keine weiteren Elemente, insbesondere nicht die Halteplatte und nicht die Montagefläche, mit einbezieht. The mounting plate also has attachment points for screwing on the door operator, which are referred to here as second attachment points. The second attachment points are, in particular, holes with an internal thread. Alternatively, these attachment points could be threaded rods, for example. The second fastening points are designed in such a way that the door operator can be fastened to the mounting plate, this fastening not involving any further elements, in particular not the retaining plate and not the mounting surface.
Es ist auch möglich, dass die Montageplatte fest mit dem Türbetätiger verbunden ist, beispielsweise integraler Bestandteil des Gehäuses des Türbetätigers ist. Insbesondere ist dann die Montageplatte nicht zerstörungsfrei vom Türbetätiger lösbar. Bei dieser Ausgestaltung ist jedoch darauf zu achten, dass die ersten Befestigungspunkte zum Befestigen der Halteplatte an der Montagefläche, insbesondere zum
Einsetzen von Schrauben, zugänglich sein müssen. Z. B. wegen dieser Zugänglichkeit der ersten Befestigungspunkte ergibt sich in den meisten Fällen die praktikable Lösung, dass der Türbetätiger an der Montageplatte angeschraubt ist. Dadurch kann zunächst die gesamte Brandschutzbefestigungseinrichtung an der Montagefläche befestigt werden, worauf im nächsten Schritt der Türbetätiger an der Brandschutzbefestigungseinrichtung, also der Montageplatte, befestigt wird. It is also possible that the mounting plate is firmly connected to the door operator, for example, is an integral part of the housing of the door operator. In particular, the mounting plate cannot then be detached from the door operator without being destroyed. In this configuration, however, care must be taken to ensure that the first attachment points for attaching the retaining plate to the mounting surface, in particular to the Insertion of screws, must be accessible. For example, due to this accessibility of the first fastening points, the practicable solution in most cases is that the door operator is screwed to the mounting plate. As a result, the entire fire protection fastening device can first be fastened to the mounting surface, whereupon the door operator is fastened to the fire protection fastening device, ie the mounting plate, in the next step.
Die Montageplatte ist vorzugsweise einteilig, insbesondere aus Metall. Ebenso ist die Halteplatte vorzugsweise einteilig, insbesondere aus Metall. Dadurch ergibt sich eine einfache Fertigung und eine nicht brennende sowie stabile Ausgestaltung dieser Platten. The mounting plate is preferably in one piece, in particular made of metal. Likewise, the retaining plate is preferably in one piece, in particular made of metal. This results in simple production and a non-burning and stable design of these plates.
Die Halteplatte und die Montageplatte sind in ihrer senkrecht zur Montageachse erstreckenden Dimension möglichst gleich groß gestaltet. Dadurch können diese beiden Platten über eine möglichst große Fläche aneinander anliegen und die entsprechenden Befestigungspunkte können über eine möglichst große Fläche verteilt werden. Des Weiteren ergibt sich eine einheitliche und ansprechende optische Gestaltung. Insbesondere ist vorgesehen, dass sich die Halteplatte senkrecht zur Montageachse über eine erste Querschnittsfläche erstreckt und sich die Montageplatte senkrecht zur Montageachse über eine zweite Querschnittsfläche erstreckt. Insbesondere ist ein Verhältnis der ersten Querschnittsfläche zur zweiten Querschnittsfläche zwischen 0,7 und 1,3, vorzugsweise zwischen 0,8 und 0,9, besonders vorzugsweise zwischen 0,9 und 1,1. The holding plate and the mounting plate are designed to be as large as possible in their dimension extending perpendicularly to the mounting axis. As a result, these two plates can rest against one another over as large an area as possible and the corresponding attachment points can be distributed over as large an area as possible. Furthermore, the result is a uniform and attractive visual design. In particular, it is provided that the retaining plate extends perpendicularly to the assembly axis over a first cross-sectional area and the mounting plate extends perpendicularly to the assembly axis over a second cross-sectional area. In particular, a ratio of the first cross-sectional area to the second cross-sectional area is between 0.7 and 1.3, preferably between 0.8 and 0.9, particularly preferably between 0.9 and 1.1.
Parallel zur Montageachse ist eine Dicke der Halteplatte an ihrer dicksten Stelle definiert. Diese Dicke der Halteplatte liegt vorzugsweise zwischen 1 mm und 20 mm, besonders vorzugsweise zwischen 2 mm und 10 mm.
Parallel zur Montageachse ist eine Dicke der Montageplatte an ihrer dicksten Stelle definiert. Vorzugsweise liegt die Dicke der Montageplatte zwischen 1 mm und 30 mm, vorzugsweise zwischen 5 mm und 20 mm. A thickness of the holding plate at its thickest point is defined parallel to the assembly axis. This thickness of the holding plate is preferably between 1 mm and 20 mm, particularly preferably between 2 mm and 10 mm. A thickness of the mounting plate at its thickest point is defined parallel to the mounting axis. The thickness of the mounting plate is preferably between 1 mm and 30 mm, preferably between 5 mm and 20 mm.
Vorzugsweise ist vorgesehen, dass in der einzelnen Reaktionskammer ausschließlich das intumeszierende Material ohne sonstige Teile angeordnet sind. Bei dem Antriebselement, bzw. dem intumeszierenden Material, handelt es sich insbesondere um ein flächiges plattenförmiges Material, das beliebig zuschneidbar ist. Insbesondere ist vorgesehen, um einen möglichst flachen Aufbau zu erreichen, dass lediglich eine Schicht dieses plattenförmigen Materials pro Reaktionskammer eingelegt ist. It is preferably provided that only the intumescent material without any other parts is arranged in the individual reaction chamber. The drive element or the intumescent material is, in particular, a flat, plate-shaped material that can be cut to any desired size. In particular, in order to achieve a structure that is as flat as possible, only one layer of this plate-shaped material is inserted per reaction chamber.
Das Antriebselement erstreckt sich vorzugsweise über die gesamte, senkrecht zur Montageachse definierte Querschnittsfläche der Reaktionskammer. Dadurch ist die gesamte Reaktionskammer mit dem Antriebselement gefüllt und es steht möglichst viel des intumeszierenden Materials zur Verfügung. The drive element preferably extends over the entire cross-sectional area of the reaction chamber defined perpendicular to the assembly axis. As a result, the entire reaction chamber is filled with the drive element and as much of the intumescent material as possible is available.
Die einzelne Reaktionskammer weist senkrecht zur Montageachse eine Querschnittsfläche auf. Diese Querschnittsfläche der Reaktionskammer ist vorzugsweise rechteckig, da sich bei dieser geometrischen Ausgestaltung möglichst viele Reaktionskammern bzw. Reaktionskammern mit großer Fläche über die Brandschutzbefestigungseinrichtung verteilen lassen. Allerdings sind auch andere Querschnittsflächen möglich. The single reaction chamber has a cross-sectional area perpendicular to the mounting axis. This cross-sectional area of the reaction chamber is preferably rectangular since, with this geometric design, as many reaction chambers or reaction chambers with a large area as possible can be distributed over the fire protection fastening device. However, other cross-sectional areas are also possible.
Die Brandschutzbefestigungseinrichtung ist möglichst flach ausgebildet und ist möglichst so gestaltet, dass sie unauffällig zwischen Türbetätiger und Montagefläche angeordnet werden kann. Die Tiefe der einzelnen
Reaktionskammern liegt vorzugsweise zwischen 1 mm und 15 mm, insbesondere zwischen 2 mm und 10 mm. 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. The depth of each Reaction chambers is preferably between 1 mm and 15 mm, in particular between 2 mm and 10 mm.
Senkrecht zur Montageachse ist die Querschnittsfläche der einzelnen Reaktionskammer 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 chamber is defined perpendicularly 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 Querschnittsfläche entsprechend viel Kraft zum Wegdrücken des Türbetätigers aufgebraucht werden kann. So beträgt die Summe aller Querschnittsflächen 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 .
Die Erfindung umfasst ferner eine Anordnung mit einem Türbetätiger und der vorab beschriebenen Brandschutzbefestigungseinrichtung. Der Türbetätiger ist zur Anordnung an der Montageplatte, insbesondere zum Anschrauben an der Montageplatte, ausgebildet. Besonders bevorzugt ist der Türbetätiger an der Montageplatte angeschraubt. Bei dem Türbetätiger handelt es sich insbesondere um einen Türschließer oder einen Türantrieb. Insbesondere weist der Türbetätiger ein Gehäuse auf, beispielsweise aus Druckguss. In dem Gehäuse befindet sich insbesondere zumindest eine Hydraulikkammer, in der sich das brennbare Fluid befindet. The invention also includes an arrangement with a door operator and the fire protection attachment device described above. The door operator is designed to be arranged on the mounting plate, in particular to be screwed onto the mounting plate. The door operator is particularly preferably screwed to the mounting plate. The door operator is in particular a door closer or a door drive. In particular, the door operator has a housing, for example made of die-cast. In the housing there is in particular at least one hydraulic chamber in which the combustible fluid is located.
Die im Zusammenhang mit der erfindungsgemäßen Brandschutzbefestigungseinrichtung beschriebenen vorteilhaften Ausgestaltungen und Unteransprüche finden entsprechend vorteilhafte Anwendung für die Anordnung.
Insbesondere ist vorgesehen, dass die Anordnung eine Verkleidung umfasst, die den Türbetätiger abdeckt. Die Verkleidung ist insbesondere zur direkten Befestigung an der Montageplatte ausgebildet. Insbesondere weist die Montageplatte an zumindest einer Stelle eine Formschlusskontur auf, die zur formschlüssigen Aufnahme der Verkleidung ausgebildet ist. Insbesondere sind die Montageplatte und die Verkleidung so ausgebildet, dass die Verkleidung die Montageplatte abdeckt, so dass die Montageplatte nach außen hin nicht oder zumindest nicht vollständig an ihrem Umfang sichtbar ist. Dadurch bleibt lediglich die Halteplatte, die jedoch relativ dünn ausgestaltet ist, sichtbar. The advantageous configurations and dependent claims described in connection with the fire protection fastening device according to the invention are correspondingly advantageously used for the arrangement. In particular, it is provided that the arrangement includes a panel that covers the door operator. The cladding is designed in particular for direct attachment to the mounting plate. In particular, the mounting plate has a form-fitting contour at least at one point, which is designed to receive the paneling in a form-fitting manner. In particular, the mounting plate and the cladding are designed in such a way that the cladding covers the mounting plate, so that the mounting plate is not visible from the outside, or at least not completely at its periphery. As a result, only the retaining plate, which is designed to be relatively thin, remains visible.
Die Erfindung umfasst ferner eine Türanordnung. Die Türanordnung wiederum umfasst die soeben beschriebene Anordnung als auch die Montagefläche. Insbesondere umfasst die Türanordnung die Tür, Zarge oder Wand, die die Montagefläche bildet. Die Halteplatte ist zur Befestigung an der Montagefläche ausgebildet. Insbesondere ist die Halteplatte an der Montageplatte befestigt, vorzugsweise angeschraubt. The invention also includes a door assembly. The door assembly in turn includes the assembly just described as well as the mounting surface. In particular, the door arrangement includes the door, frame or wall that forms the mounting surface. The retaining plate is designed to be attached to the mounting surface. In particular, the holding plate is fastened to the mounting plate, preferably screwed on.
Zusammenfassend zeigt die Erfindung eineIn summary, the invention shows a
Brandschutzbefestigungseinrichtung, die unabhängig von der Struktur der Montagefläche eine wirksame Abtrennfunktion des Türbetätigers erfüllen kann. Dies wird durch die Aufteilung in zwei Funktionsebenen, also die Halteplatte und die Montageplatte, erreicht. Dadurch kann insbesondere eine herkömmlich zu verwendende Montageplatte ersetzt werden. Die montageseitige Befestigung erfolgt über eine sehr steife Halteplatte, die für sich die Befestigung an der Montagefläche sicherstellt und gleichzeitig eine sehr robuste Abstützung für das intumeszierende Material darstellt. Die Halteplatte verbleibt auch nach der Abtrennung des Türbetätigers an der Montagefläche, stellt aber aufgrund der Materialwahl, insbesondere Metall, keine Entzündungsgefahr dar.
Die Verbindung zwischen den beiden Funktionsebenen, also die Verbindung zwischen Halteplatte und Montageplatte, wird durch entsprechend gewählte Verbindungselemente übernommen, die für eine definierte Festigkeit in genau definierte Gewinde eingreifen. Damit ist einerseits die Überleitung der Betriebskräfte vom Türbetätiger in die Montagefläche sichergestellt, aber gleichzeitig auch eine sichere Ablösung von Halteplatte und Montageplatte im Brandfall möglich. Ein weiterer Vorteil der Erfindung ist, dass die Montageplatte und Halteplatte werksseitig vormontiert werden können und so eine montagefertige Brandschutzbefestigungseinrichtung zur Verfügung gestellt werden kann. Fire protection fastening device, which can perform an effective disconnection function of the door operator, regardless of the structure of the mounting surface. This is achieved by dividing it into two functional levels, i.e. the holding plate and the mounting plate. In this way, in particular, a mounting plate that is to be used conventionally can be replaced. The assembly-side fastening is carried out using a very stiff retaining plate, which in itself ensures fastening to the mounting surface and at the same time represents a very robust support for the intumescent material. The retaining plate remains on the mounting surface even after the door actuator has been detached, but due to the choice of material, especially metal, it does not pose a risk of ignition. The connection between the two functional levels, i.e. the connection between the retaining plate and the mounting plate, is provided by appropriately selected connecting elements that engage in precisely defined threads for a defined strength. On the one hand, this ensures that the operating forces are transferred from the door operator to the mounting surface, but at the same time it is also possible to safely detach the retaining plate and mounting plate in the event of a fire. A further advantage of the invention is that the mounting plate and retaining plate can be pre-assembled at the factory and a ready-to-install fire protection fastening device can thus be made available.
Durch die vollständige Einkammerung des Antriebselements in den geschlossenen Reaktionskammern wird eine optimale Wirksamkeit des Antriebselements bzw. intumeszierenden Materials erreicht, was insbesondere eine einlagige Ausführung dieses relativ kostenintensiven Materials erlaubt. Due to the complete encapsulation of the drive element in the closed reaction chambers, an optimal effectiveness of the drive element or intumescent material is achieved, which in particular allows a single-layer design of this relatively expensive material.
