Description

Die Erfindung betrifft eine Brandschutzklappe mit einem Gehäuse für eine darin schwenkbar um eine Schwenkachse herum gelagerte Absperrklappe und mit einem das Gehäuse außenseitig umgebenen Einbausatz, wobei der Einbausatz zumindest eine Platte, vorzugsweise zumindest zwei benachbart zueinander angeordnete Platten, umfasst, wobei jede Platte wenigstens zwei Plattensegmente umfasst und so ausgebildet ist, dass die Gesamtheit aller Plattensegmente der jeweiligen Platte eine Aussparung zur Aufnahme des Gehäuses bildet, wobei jedes Plattensegment seitlich von außen, insbesondere in radialer Richtung, um das Gehäuse herum anbringbar ist, und wobei die zugehörigen Plattensegmente jeder Platte sich an zwei Stoßkanten mit dem oder den anderen Plattensegment(en) berühren, wobei das Gehäuse weiterhin außenseitig von zumindest einem Rahmen umfasst ist.The invention relates to a fire protection flap with a housing for a shut-off flap mounted therein so that it can pivot about a pivot axis, and with an installation kit surrounding the housing on the outside, the installation kit comprising at least one plate, preferably at least two plates arranged adjacent to one another, with each plate having at least two plate segments and is designed in such a way that all of the plate segments of the respective plate form a recess for accommodating the housing, with each plate segment being attachable laterally from the outside, in particular in the radial direction, around the housing, and with the associated plate segments of each plate adjoining touch two abutting edges with the or the other plate segment (s), wherein the housing is further surrounded on the outside of at least one frame.

Die EP 2 570 158 A1 offenbart ein gattungsgemäße Brandschutzklappe mit den Merkmalen des Oberbegriffs von Anspruch 1.the EP 2 570 158 A1 discloses a generic fire damper with the features of the preamble of claim 1.

Jeder Rahmen weist eine geschlossene Ausnehmung zur Aufnahme des Gehäuses auf. Im Werk wird das Gehäuse in die Ausnehmung hineingeschoben, und durch geeignetes Befestigungsmaterial wird der Rahmen an dem Gehäuse fixiert. Als nachteilig erweist sich die Montage, da durch die geschlossene Ausbildung des Rahmens das Gehäuse zunächst in die Ausnehmung hineingeschoben wird und anschließend die erforderliche Anzahl an Plattensegmenten in Abhängigkeit der zu erzielenden Anzahl an Platten um das Gehäuse herum angebracht wird.Each frame has a closed recess for receiving the housing. The housing is pushed into the recess at the factory, and the frame is fixed to the housing using suitable fastening material. The assembly proves to be disadvantageous, since the closed design of the frame means that the housing is first pushed into the recess and then the required number of plate segments depending on the number of plates to be achieved around the housing placed around.

Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und eine Brandschutzklappe anzugeben, deren Einbausatz einfacher und schneller montierbar ist.The object of the invention is to avoid the aforementioned disadvantages and to specify a fire damper whose installation kit can be installed more easily and quickly.

Erfindungsgemäß wird zur Lösung dieser Aufgabe eine Brandschutzklappe mit den Merkmalen von Anspruch 1 vorgeschlagen. Erfindungsgemäß ist dabei vorgesehen, dass jeder Rahmen wenigstens zwei Rahmensegmente umfasst und jeder Rahmen so ausgebildet ist, dass die Gesamtheit aller Rahmensegmente des jeweiligen Rahmens eine Ausnehmung zur Aufnahme des Gehäuses bildet, wobei jedes Rahmensegment seitlich von außen, insbesondere in radialer Richtung, um das Gehäuse herum anbringbar ist, wobei die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente ohne Überlappung in einer orthogonal zu der von den Rahmensegmenten dieses Rahmens aufgespannten Ebene gesehenen Richtung aneinander angrenzend und einander berührend vorgesehen sind und wobei weiterhin die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente durch zumindest ein separates Fixierelement mittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert sind, wobei jedes Rahmensegment zweier angrenzender Rahmensegmente in seinem jeweiligen Endbereich, der mit dem Endbereich des angrenzenden Rahmensegmentes zusammenwirkt, jeweils wenigstens einen von außen seitlich zugänglichen Einführbereich, vorzugsweise einen als Einführöffnung ausgebildeten Einführbereich, aufweist, und dass die beiden Endbereiche dieser beiden aneinandergrenzenden Rahmensegmente durch wenigstens eine als Fixierelement ausgebildete Klammer, die mit einem Teilbereich in zumindest einen Einführbereich des einen Rahmensegmentes und mit einem anderen Teilbereich in zumindest einen Einführbereich des anderen Rahmensegmentes hineingreift, fixiert sind.According to the invention, a fire damper with the features of claim 1 is proposed to solve this problem. According to the invention, it is provided that each frame comprises at least two frame segments and each frame is designed in such a way that all of the frame segments of the respective frame form a recess for receiving the housing, with each frame segment being wrapped around the housing laterally from the outside, in particular in the radial direction can be attached around, wherein the cooperating end regions of two adjacent frame segments are provided without overlapping in a direction orthogonal to the plane spanned by the frame segments of this frame, adjoining and touching each other and wherein furthermore the cooperating end regions of two adjacent frame segments are indirectly fixed by at least one separate fixing element in Reference to a relative movement are fixed to each other in at least one direction, each frame segment of two adjacent frame segments in its respective end portion, which is connected to the end portion of the adjacent frame segments s interacts, in each case has at least one insertion area that is laterally accessible from the outside, preferably an insertion area designed as an insertion opening, and that the two end areas of these two adjacent frame segments are secured by at least one clamp designed as a fixing element, which has a partial area in at least one insertion area of the one frame segment and with another partial area in at least one insertion area of the other frame segment engages, are fixed.

Die erfindungsgemäße Ausgestaltung erlaubt eine einfache Montage, da lediglich die erforderliche Anzahl an Rahmensegmenten seitlich von außen um das Gehäuse so herum angelegt werden müssen, dass die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente ohne Überlappung aneinander angrenzend und einander berührend vorgesehen sind. Die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente sind durch zumindest ein separates Fixierelement mittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert.The configuration according to the invention permits simple assembly since only the required number of frame segments must be placed laterally around the housing from the outside in such a way that the cooperating end regions of two adjacent frame segments are provided adjoining and touching one another without overlapping. The cooperating end regions of two adjacent frame segments are indirectly fixed by at least one separate fixing element with respect to a relative movement to one another in at least one direction.

Die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente grenzen ohne Überlappung in einer orthogonal zu der von den Rahmensegmenten dieses Rahmens aufgespannten Ebene gesehenen Richtung aneinander. Damit überlappen sich die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente eines Rahmens in Strömungsrichtung gesehen nicht. Die Rahmensegmente können stumpf aneinanderstoßen oder beispielsweise nach Art von Puzzle-Stücken ineinandergreifen.The cooperating end regions of two adjacent frame segments adjoin one another without overlapping in a direction orthogonal to the plane spanned by the frame segments of this frame. As a result, the interacting end regions of two adjacent frame segments of a frame, seen in the direction of flow, do not overlap. The frame segments can abut one another or interlock, for example, in the manner of jigsaw puzzle pieces.

Der Einbausatz der erfindungsgemäßen Brandschutzklappe kann damit selbst noch vor Ort montiert werden.The installation kit of the fire damper according to the invention can thus be assembled on site.

Durch die erfindungsgemäße Ausgestaltung kann auch die Lagerhaltung erleichtert werden. So muss lediglich die Brandschutzklappe bevorratet werden. Separat hiervon können die Komponenten für die Erstellung des gewünschten Einbausatzes, d.h. die Plattensegmente und die Rahmensegmente, gelagert werden. Vor Ort kann dann der Einbausatz in der gewünschten Ausgestaltung zusammengestellt und montiert werden.Storage can also be facilitated by the configuration according to the invention. Only the fire damper needs to be stocked. The components for creating the desired installation set, i.e. the plate segments and the frame segments, can be stored separately from this. The installation kit can then be put together and installed on site in the desired configuration.

Die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente werden durch zumindest ein separates Fixierelement mittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert, wobei jedes Rahmensegment zweier angrenzender Rahmensegmente in seinem jeweiligen Endbereich, der mit dem Endbereich des angrenzenden Rahmensegmentes zusammenwirkt, jeweils wenigstens einen von außen seitlich zugänglichen Einführbereich, vorzugsweise einen als Einführöffnung ausgebildeten Einführbereich, aufweist, und dass die beiden Endbereiche dieser beiden aneinandergrenzenden Rahmensegmente durch wenigstens eine als Fixierelement ausgebildete Klammer, die mit einem Teilbereich in zumindest einen Einführbereich des einen Rahmensegmentes und mit einem anderen Teilbereich in zumindest einen Einführbereich des anderen Rahmensegmentes hineingreift, fixiert sind. Für eine Montage bei einer solchen Ausgestaltung müssen lediglich die Rahmensegmente, die gemeinsam einen Rahmen bilden, um das Gehäuse herumgelegt werden. Anschließend wird jede Klammer von außen, d.h. radial zum Gehäuse und damit orthogonal zur Strömungsrichtung in dem Gehäuse, in den entsprechenden Einführbereich eingeführt und damit die beiden Endbereiche zweier aneinandergrenzender Rahmensegmente gegeneinander fixiert. Sofern ein Rahmen aus zwei Rahmensegmenten besteht, sind insoweit zwei Klammern erforderlich.The cooperating end regions of two adjacent frame segments are indirectly fixed by at least one separate fixing element with respect to relative movement to one another in at least one direction, each frame segment of two adjacent frame segments having in its respective end area, which interacts with the end area of the adjacent frame segment, at least one insertion area that is laterally accessible from the outside, preferably an insertion area designed as an insertion opening, and that the Both end areas of these two adjoining frame segments are fixed by at least one clamp designed as a fixing element, part of which engages in at least one insertion area of one frame segment and another part in at least one insertion area of the other frame segment. For assembly in such an embodiment, only the frame segments, which together form a frame, have to be placed around the housing. Each clamp is then inserted from the outside, ie radially to the housing and thus orthogonally to the direction of flow in the housing, into the corresponding insertion area and the two end areas of two adjacent frame segments are thus fixed to one another. If a frame consists of two frame segments, two brackets are required.

Zumindest ein Plattensegment und zumindest ein benachbartes Rahmensegment, die in dem am Gehäuse angelegten Zustand mit wenigstens der Hälfte ihrer Fläche aneinander anliegend angeordnet sind, können vor dem Anlegen an die Außenseite des Gehäuses bereits untereinander fixiert sein. Sofern zumindest ein Plattensegment und zumindest ein benachbartes Rahmensegment bereits untereinander fixiert sind, ist eine Montage des Einbausatzes in Form von Blöcken möglich. Die "Paarung" von Plattensegment und von benachbartem Rahmensegment kann hinsichtlich der Anzahl und der Reihenfolge beliebig sein. Eine Paarung kann beispielsweise aus einem Plattensegment und aus einem benachbarten Rahmensegment bestehen. Auch andere Ausgestaltungen, wie beispielsweise ein Plattensegment und mehrere Rahmensegmente, sind möglich. Sofern beispielsweise das Gehäuse einen rechteckigen Querschnitt aufweist und beispielsweise die jeweiligen zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente im Bereich einer der vier Ecken des Gehäuses angeordnet sind, werden zunächst vier Blöcke hergestellt, in dem die erforderliche Anzahl an Plattensegmenten und Rahmensegmenten untereinander, beispielsweise durch Verschrauben, fixiert werden. Die Anzahl und die Anordnung des (der) Rahmensegments (Rahmensegmente) und/oder des (der) Plattensegments (Plattensegmente) ist bei allen vier Blöcken gleich. Anschließend werden die Blöcke so an das Gehäuse angelegt, dass die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente entweder unmittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert oder alternativ durch zumindest ein separates Fixierelement mittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert sind. Durch die Blockmontage kann die Montagezeit reduziert werden. Der so hergestellte Einbausatz weist zudem eine hohe Stabilität auf.At least one plate segment and at least one adjacent frame segment, which in the state in which they are placed on the housing are arranged so that at least half of their surface area is in contact with one another, can be be fixed to the outside of the housing already under each other. If at least one plate segment and at least one adjacent frame segment are already fixed to one another, the installation kit can be assembled in the form of blocks. The "pairing" of plate segment and adjacent frame segment can be arbitrary in terms of number and sequence. A pairing can consist, for example, of a plate segment and an adjacent frame segment. Other configurations, such as a plate segment and several frame segments, are also possible. If, for example, the housing has a rectangular cross section and, for example, the respective interacting end areas of two adjacent frame segments are arranged in the area of one of the four corners of the housing, four blocks are first produced by fixing the required number of plate segments and frame segments to one another, for example by screwing will. The number and arrangement of the frame segment(s) and/or plate segment(s) is the same for all four blocks. The blocks are then placed on the housing in such a way that the interacting end regions of two adjacent frame segments are either fixed directly in relation to a relative movement to one another in at least one direction or alternatively are indirectly fixed in relation to a relative movement to one another in at least one direction by at least one separate fixing element . The assembly time can be reduced by the block assembly. The installation kit produced in this way also has a high level of stability.

Bei einem bevorzugten Ausführungsbeispiel können alle Plattensegmente und ihre jeweils benachbarten Rahmensegmente, welche in dem am Gehäuse angelegten Zustand jeweils mit wenigstens der Hälfte ihrer Fläche aneinander anliegend angeordnet sind, vor dem Anlegen an die Außenseite des Gehäuses jeweils untereinander fixiert sein. Diese Ausgestaltung ermöglicht wiederum eine Montage des Einbausatzes in Form von Blöcken. Die "Paarung" von Plattensegment und von benachbartem Rahmensegment kann hinsichtlich der Anzahl und der Reihenfolge beliebig sein. Eine Paarung kann beispielsweise aus einem Plattensegment und aus einem benachbarten Rahmensegment bestehen. Auch andere Ausgestaltungen, wie beispielsweise ein Plattensegment und mehrere Rahmensegmente, sind möglich. Sofern beispielsweise das Gehäuse einen rechteckigen Querschnitt aufweist und beispielsweise die jeweiligen zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente im Bereich einer der vier Ecken des Gehäuses angeordnet sind, werden zunächst vier Blöcke hergestellt, indem die erforderliche Anzahl an Plattensegmenten und Rahmensegmenten untereinander, beispielsweise durch Verschrauben, fixiert werden. Die Anzahl und die Anordnung des (der) Rahmensegments (Rahmensegmente) und/oder des (der) Plattensegments (Plattensegmente) ist bei allen vier Blöcken gleich. Anschließend werden die Blöcke so an das Gehäuse angelegt, dass die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente entweder unmittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert oder alternativ durch zumindest ein separates Fixierelement mittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung fixiert sind.In a preferred embodiment, all plate segments and their respective adjacent frame segments, which are arranged in contact with the housing with at least half of their surfaces lying against one another, can be fixed to one another before they are placed on the outside of the housing. This configuration in turn allows the installation kit to be assembled in the form of blocks. The "pairing" of plate segment and adjacent frame segment can be arbitrary in terms of number and sequence. A pairing can consist, for example, of a plate segment and an adjacent frame segment. Other configurations, such as a plate segment and several frame segments, are also possible. If, for example, the housing has a rectangular cross section and, for example, the respective interacting end regions of two adjacent frame segments are arranged in the area of one of the four corners of the housing, four blocks are first produced by the required number of plate segments and frame segments being fixed to one another, for example by screwing . The number and arrangement of the frame segment(s) and/or plate segment(s) is the same for all four blocks. The blocks are then placed on the housing in such a way that the interacting end regions of two adjacent frame segments are either fixed directly in relation to a relative movement to one another in at least one direction or alternatively are indirectly fixed in relation to a relative movement to one another in at least one direction by at least one separate fixing element .

Zumindest ein Rahmen kann aus einem flachen und eben ausgebildeten Blech bestehen. Damit hat der Rahmen eine geringe Dicke. Das Blech besteht aus einem geeigneten Metall, wie zum Beispiel Stahl oder Eisen. Selbstverständlich sind auch andere geeignete Metalle denkbar. Das Blech ist mit seiner dem Gehäuse zugewandten die Ausnehmung bildenden Innenkante mit der Außenseite des Gehäuses in Kontakt und erstreckt sich orthogonal zum Gehäuse.At least one frame can consist of a flat and evenly formed metal sheet. The frame thus has a small thickness. The sheet metal is made of a suitable metal such as steel or iron. Of course, other suitable metals are also conceivable. The metal sheet is in contact with the outside of the housing with its inner edge facing the housing and forming the recess and extends orthogonally to the housing.

Zumindest eine Klammer kann aus einem, vorzugsweise flachen und eben ausgebildeten, Blech bestehen. Das Blech besteht aus einem geeigneten Metall, wie zum Beispiel Stahl oder Eisen. Selbstverständlich sind auch andere geeignete Metalle denkbar.At least one clip can consist of a preferably flat and planar sheet metal. The sheet metal is made of a suitable metal such as steel or iron. Of course, other suitable metals are also conceivable.

Der Rahmen und zumindest eine Klammer dieses Rahmens, vorzugsweise alle Klammern dieses Rahmens, können die gleiche Dicke aufweisen.The frame and at least one bracket of this frame, preferably all brackets of this frame, can have the same thickness.

Zumindest eine Klammer kann eine u-förmige Ausgestaltung unter Bildung eines Stegs und zweier daran angeformter, vorzugsweise parallel ausgerichteter, Fixierschenkeln aufweisen.At least one clamp can have a U-shaped configuration, forming a web and two fixing legs formed thereon and preferably aligned parallel.

Dabei können die Rahmensegmente zweier angrenzender Rahmensegmente in ihren angrenzenden Endbereichen einen gemeinsamen Aufnahmebereich zur Aufnahme eines Teilbereichs der Klammer, vorzugsweise des Steges der Klammer, bilden. Der Aufnahmebereich ist von außen seitlich zugänglich. Im eingeführten Zustand befindet sich beispielsweise der Steg der Klammer in dem Aufnahmebereich, so dass die Klammer in ihrer Fixierposition nicht seitlich über die Außenkontur des Rahmens hervorsteht.The frame segments of two adjoining frame segments can form a common receiving area in their adjoining end areas for receiving a partial area of the clip, preferably the web of the clip. The recording area is accessible from the outside from the side. In the inserted state, for example, the web of the clip is in the receiving area, so that the clip does not protrude laterally beyond the outer contour of the frame in its fixing position.

Es bietet sich an, wenn sich bei zumindest einer Klammer jeder der beiden Fixierschenkel eine Innenfläche aufweist, wobei die Innenflächen beider Fixierschenkel aufeinander zuweisend ausgerichtet sind, und wenn sich bei zumindest einer Klammer der Abstand A zwischen den beiden Innenflächen vom freien Ende eines jeden Fixierschenkels zum Steg hin, d. h. entgegen die Einführrichtung gesehen, zumindest in einem Teilbereich reduziert. So können die Fixierschenkel von ihrem freien Ende zum Steg hin gesehen aufeinander zulaufend ausgerichtet sein. Bei einer Ausgestaltung als ebenes Blech bietet es sich an, wenn die Breite zumindest eines Fixierschenkels im Bereich der dem anderen Fixierschenkel zugewandten, die Innenfläche bildenden Kante zunimmt. Sofern sich der Abstand A zwischen den beiden Innenflächen nur in einem Teilbereich reduziert, sind die Innenflächen in dem verbleibenden Teilbereich parallel ausgerichtet.It is advisable if, in the case of at least one clamp, each of the two fixing legs has an inner surface, with the inner surfaces of both fixing legs being aligned facing one another, and if, in the case of at least one clamp, the distance A between the two inner surfaces from the free end of each fixing leg to the jetty, d. H. Seen against the direction of insertion, reduced at least in a partial area. Thus, the fixing legs can be aligned so as to run towards one another, viewed from their free end towards the web. In the case of an embodiment as a flat metal sheet, it is advisable if the width of at least one fixing leg increases in the region of the edge that faces the other fixing leg and forms the inner surface. If the distance A between the two inner surfaces is only reduced in a partial area, the inner surfaces are aligned in parallel in the remaining partial area.

Auch bietet es sich an, wenn jeder Einführbereich eine Wirkfläche aufweist, wobei die Wirkflächen der zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente im fixierten Zustand voneinander wegweisen und in einem Abstand B zueinander angeordnet sind.It is also useful if each insertion area has an active surface, with the active surfaces of the interacting end regions of two adjacent frame segments pointing away from one another in the fixed state and being arranged at a distance B from one another.

Im fixierten Zustand der zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente kann der Abstand A maximal dem Abstand B entsprechen.In the fixed state of the interacting end regions of two adjacent frame segments, the distance A can correspond to the distance B at most.

Dabei kann zumindest eine Wirkfläche eines Rahmensegmentes, vorzugsweise beide Wirkflächen zweier angrenzender Rahmensegmente, zumindest in einem Teilbereich derart schräg ausgebildet sein, dass der Abstand B in Einführrichtung gesehen zumindest in dem Teilbereich zunimmt. Sofern sich die schräge Ausbildung nur auf einen Teilbereich erstreckt, sind die beiden Wirkflächen der beiden angrenzenden Rahmensegmente in dem verbleibenden Teilbereich parallel ausgerichtet.In this case, at least one active surface of a frame segment, preferably both active surfaces of two adjacent frame segments, can be designed at an angle at least in a partial area such that the distance B is in the direction of insertion seen increases at least in the sub-area. If the sloping configuration only extends to a partial area, the two active surfaces of the two adjacent frame segments are aligned in parallel in the remaining partial area.

Für eine Erleichterung des Einführens eines Fixierschenkels in den Einführbereich bietet es sich an, wenn sich zumindest ein Fixierschenkel zu seinem freien Ende hin verjüngt.To make it easier to insert a fixing leg into the insertion area, it is advisable if at least one fixing leg tapers towards its free end.

Zumindest eines der beiden Rahmensegmente zweier aneinandergrenzender Rahmensegmente kann in seinem Endbereich zumindest einen in Richtung des Endbereichs des zweiten Rahmensegmentes weisenden Vorsprung aufweisen, und der mit dem besagten Endbereich des ersten Rahmensegmentes zusammenwirkende Endbereich des zweiten Rahmensegmentes kann zumindest einen mit dem Vorsprung korrespondierenden Aufnahmebereich aufweisen, so dass bei einem Eingriff des Vorsprungs in den korrespondierenden Aufnahmebereich eine Verlagerung der beiden aneinandergrenzenden Rahmensegmente orthogonal zur Blockierrichtung der beiden, vorzugsweise durch die Klammer, fixierten Enden der Rahmensegmente verhindert ist.At least one of the two frame segments of two adjacent frame segments can have in its end area at least one projection pointing in the direction of the end area of the second frame segment, and the end area of the second frame segment that interacts with said end area of the first frame segment can have at least one receiving area corresponding to the projection, see above that when the projection engages in the corresponding receiving area, a displacement of the two adjoining frame segments orthogonal to the blocking direction of the two ends of the frame segments, which are preferably fixed by the clamp, is prevented.

Zumindest ein Rahmen kann im montierten Zustand die gleichen Abmessungen wie wenigstens einer der beiden unmittelbar angrenzenden Platten aufweisen.When assembled, at least one frame can have the same dimensions as at least one of the two immediately adjacent panels.

Dabei kann auf beiden Seiten zumindest eines Rahmens jeweils zumindest eine Platte angeordnet sein.At least one plate can be arranged on both sides of at least one frame.

Zumindest eine Platte kann Silikate, insbesondere Kalziumsilikat, beinhalten. Selbstverständlich sind auch andere geeignete Materialien denkbar.At least one plate can contain silicates, in particular calcium silicate. Of course, other suitable materials are also conceivable.

In allen Figuren werden für gleiche bzw. gleichartige Bauteile übereinstimmende Bezugszeichen verwendet.The same reference numbers are used in all figures for the same or similar components.

Die Figuren 1 und 3 zeigen zwei unterschiedliche Ausführungsbeispiele einer Brandschutzklappe mit einem Gehäuse 1 für eine darin schwenkbar um eine Schwenkachse herum gelagerte Absperrklappe 2. Die Absperrklappe 2 ist mittels eines auf der Außenseite des Gehäuses 1 angeordneten Antriebs 3 in ihrer Stellung verlagerbar. Jede Brandschutzklappe weist außenseitig einen Einbausatz auf, der zumindest eine Platte 4 sowie einen Rahmen 5 umfasst.the figures 1 and 3 show two different exemplary embodiments of a fire protection flap with a housing 1 for a shut-off flap 2 mounted therein so that it can pivot about a pivot axis. Each fire damper has an installation kit on the outside, which includes at least one plate 4 and a frame 5 .

Jede Platte 4 ist beispielsweise aus Silikat und besteht bei der Ausgestaltung nach Figur 1 aus zwei Plattensegmenten 4a, die so ausgebildet sind, dass die Gesamtheit beider Plattensegmente 4a der jeweiligen Platte 4 eine Aussparung zur Aufnahme des runden Gehäuses 1 bildet. Jedes Plattensegment 4a ist seitlich von außen, in radialer Richtung, um das Gehäuse 1 herum anbringbar. Die zugehörigen Plattensegmente 4a jeder Platte 4 berühren sich an zwei Stoßkanten mit dem anderen Plattensegment 4a, wobei im Bereich der Stoßkanten eine Abdichtung vorgesehen ist.Each plate 4 is made of silicate, for example, and in the embodiment shown in FIG figure 1 of two plate segments 4a, which are designed in such a way that the entirety of both plate segments 4a of the respective plate 4 forms a recess for accommodating the round housing 1. Each plate segment 4a can be fitted around the housing 1 laterally from the outside in the radial direction. The associated plate segments 4a of each plate 4 touch the other plate segment 4a at two abutting edges, a seal being provided in the area of the abutting edges.

Bei dem Ausführungsbeispiel nach Fig. 1 sind fünf Platten 4 vorgesehen, wobei zwischen der zweiten Platte 4 und der dritten Platte 4 ein Rahmen 5 angeordnet ist. Damit ist auf beiden Seiten des Rahmens 5 jeweils zumindest eine Platte 4 angeordnet.In the embodiment according to 1 five plates 4 are provided, with a frame 5 being arranged between the second plate 4 and the third plate 4 . At least one plate 4 is thus arranged on each side of the frame 5 .

Bei dem Ausführungsbeispiel nach Fig. 3 bis 6 besteht jede Platte 4 aus vier streifenförmig ausgebildeten Plattensegmenten 4a, die so ausgebildet sind, dass die Gesamtheit aller Plattensegmente 4a der jeweiligen Platte 4 eine rechteckige Aussparung zur Aufnahme des rechteckigen Gehäuses 1 bildet.In the embodiment according to Figures 3 to 6 Each plate 4 consists of four strip-shaped plate segments 4a, which are designed in such a way that the entirety of all plate segments 4a of the respective plate 4 forms a rectangular recess for accommodating the rectangular housing 1.

Bei dem Ausführungsbeispiel nach Fig. 3 sind vier Platten 4 vorgesehen, wobei zwischen der ersten Platte 4 und der zweiten Platte 4 der Rahmen 5 angeordnet ist. Die vier Platten 4 weisen eine unterschiedliche Höhe und eine unterschiedliche Dicke auf. Auf beiden Seiten des Rahmens 5 ist auch bei diesem Ausführungsbeispiel jeweils eine Platte 4 angeordnet. Bei dem Ausführungsbeispiel nach Fig. 4 weist die in dieser Darstellung vordere Platte 4 auf ihrer mit dem Gehäuse 1 zusammenwirkenden Fläche noch eine Isolationsschicht 7 auf. Der Rahmen 5 bei dem Ausführungsbeispiel nach den Fig. 1 und 2 umfasst zwei Rahmensegmente 5a, die so ausgebildet sind, dass die Gesamtheit aller Rahmensegmente 5a des Rahmens 5 eine Ausnehmung zur Aufnahme des runden Gehäuses 1 bildet, wobei jedes Rahmensegment 5a seitlich von außen, in radialer Richtung, um das Gehäuse 1 herum anbringbar ist. Der Rahmen 5 bei den Ausführungsbeispielen nach den Fig. 3 bis 9 umfasst vier Rahmensegmente 5a, die so ausgebildet sind, dass die Gesamtheit aller Rahmensegmente 5a des jeweiligen Rahmens 5 eine Ausnehmung zur Aufnahme des rechteckigen Gehäuses 1 bildet, wobei jedes Rahmensegment 5a seitlich von außen, in radialer Richtung, um das Gehäuse 1 herum anbringbar ist.In the embodiment according to 3 four plates 4 are provided, with the frame 5 being arranged between the first plate 4 and the second plate 4 . The four plates 4 have different heights and different thicknesses. On both sides of the frame 5, a plate 4 is also arranged in this embodiment. In the embodiment after 4 the front plate 4 in this representation also has an insulating layer 7 on its surface interacting with the housing 1 . The frame 5 in the embodiment according to Figures 1 and 2 comprises two frame segments 5a, which are designed in such a way that the entirety of all frame segments 5a of the frame 5 forms a recess for receiving the round housing 1, each frame segment 5a being attachable laterally from the outside, in the radial direction, around the housing 1. The frame 5 in the embodiments according to Figures 3 to 9 comprises four frame segments 5a, which are designed in such a way that all of the frame segments 5a of the respective frame 5 form a recess for receiving the rectangular housing 1, with each frame segment 5a being attachable laterally from the outside, in the radial direction, around the housing 1.

Wie den Figuren zu entnehmen ist, besteht jeder Rahmen 5 aus einem flachen und eben ausgebildeten Blech, wie zum Beispiel Stahl oder Eisen. Das Blech ist mit der Außenseite des Gehäuses 1 in Kontakt und erstreckt sich orthogonal zum Gehäuse.As can be seen from the figures, each frame 5 consists of a flat and planar sheet metal, such as steel or iron. The sheet metal is in contact with the outside of the case 1 and extends orthogonally to the case.

Die Fixierung der Rahmensegmente 5a der Rahmen 5 ist insbesondere in den Fig. 7 bis 9 dargestellt. Die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a sind ohne Überlappung in einer orthogonal zu der von den Rahmensegmenten 5a dieses Rahmens 5 aufgespannten Ebene gesehenen Richtung aneinander angrenzend und einander berührend vorgesehen. Damit überlappen sich die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a eines Rahmens 5 in Strömungsrichtung 20 gesehen nicht.The fixation of the frame segments 5a of the frame 5 is particularly in the Figures 7 to 9 shown. The cooperating end portions of two adjacent frame segments 5a are provided without overlap in a direction orthogonal to the plane spanned by the frame segments 5a of this frame 5, adjoining and touching each other. As a result, the interacting end regions of two adjacent frame segments 5a of a frame 5, viewed in the flow direction 20, do not overlap.

Die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a sind bei dem nicht zur Erfindung gehörenden Beispiel nach Fig. 7 unmittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung (Blockierrichtung) 8 fixiert. Bei der in Fig. 7 dargestellten Ausführung greifen die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a nach Art von Puzzle-Stücken ineinander. Bei der in Fig. 7 dargestellten Ausgestaltung weist das eine Rahmensegment 5a zweier angrenzender Rahmensegmente 5a in seinem jeweiligen Endbereich, der mit dem Endbereich des angrenzenden Rahmensegmentes 5a zusammenwirkt, einen nach außen hin geöffneten Einführbereich 10 und das angrenzende Rahmensegment 5a in seinem Endbereich einen mit dem Einführbereich 10 korrespondierenden Einführabschnitt 19 auf. Im an dem Gehäuse 1 angebrachten Zustand, so wie er in dem nicht zur Erfindung gehörenden Beispiel derThe cooperating end portions of two adjacent frame segments 5a are in the example not belonging to the invention 7 directly in relation to a relative movement to each other in at least one direction (blocking direction) 8 fixed. At the in 7 shown embodiment engage the cooperating end portions of two adjacent frame segments 5a in the manner of jigsaw puzzle pieces. At the in 7 shown configuration one frame segment 5a of two adjacent frame segments 5a has in its respective end area, which interacts with the end area of the adjacent frame segment 5a, an insertion area 10 open to the outside and the adjacent frame segment 5a in its end area has an insertion section 19 corresponding to the insertion area 10. In the state attached to the housing 1, as in the example not belonging to the invention

Fig. 7 dargestellt ist, ist der im Endbereich des einen Rahmensegmentes 5a vorgesehene Einführabschnitt 19 in den Einführbereich 10 des angrenzenden Rahmensegmentes 5a eingeführt. Der Einführabschnitt 19 kann auch eine andere Form, beispielweise nach Art eines Pfeils, aufweisen. Dann weist der Einführbereich 10 eine entsprechend korrespondierende Ausgestaltung auf. 7 is shown, the insertion section 19 provided in the end area of one frame segment 5a is inserted into the insertion area 10 of the adjacent frame segment 5a. The insertion section 19 can also have a different shape, for example in the manner of an arrow. The insertion area 10 then has a corresponding configuration.

Bei den Ausführungsbeispielen beispielsweise nach den Fig. 5, 8 oder 9 sind die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a durch ein separates Fixierelement, das als u-förmig ausgebildete Klammer 9 ausgebildet ist, mittelbar in Bezug auf eine Relativbewegung zueinander in zumindest einer Richtung (Blockierrichtung) 8 fixiert.In the embodiments, for example, according to figure 5 , 8 or 9 the cooperating end regions of two adjacent frame segments 5a are fixed indirectly with respect to a relative movement to one another in at least one direction (blocking direction) 8 by a separate fixing element, which is designed as a U-shaped clamp 9 .

Jedes Rahmensegment 5a zweier angrenzender Rahmensegmente 5a weist in seinem jeweiligen Endbereich, der mit dem Endbereich des angrenzenden Rahmensegmentes 5a zusammenwirkt, jeweils einen von außen seitlich zugänglichen Einführbereich 10 auf. Die beiden Endbereiche dieser beiden aneinandergrenzenden Rahmensegmente 5a sind jeweils durch eine als Fixierelement ausgebildete Klammer 9, die mit ihrem einen Teilbereich, nämlich einem ersten Fixierschenkel 11, in den Einführbereich 10 des einen Rahmensegmentes 5a und mit ihrem anderen Teilbereich, nämlich einem zweiten Fixierschenkel 12, in den Einführbereich 10 des anderen Rahmensegmentes 5a hineingreift, fixiert.Each frame segment 5a of two adjoining frame segments 5a has in its respective end area, which interacts with the end area of the adjoining frame segment 5a, an insertion area 10 that is laterally accessible from the outside. The two end areas of these two adjoining frame segments 5a are each connected by a clamp 9 designed as a fixing element, which with its one part, namely a first fixing leg 11, in the insertion area 10 of the one frame segment 5a and with its other part, namely a second fixing leg 12, engages in the insertion area 10 of the other frame segment 5a, fixed.

Da der Rahmen 5 als Blech ausgebildet ist, ist damit jeder Einführbereich 10 als schlitzförmige Aussparung ausgebildet, die von den beiden angrenzenden Platten 4 seitlich begrenzt wird. Jede Klammer 9 besteht aus einem flachen und eben ausgebildeten Blech, wie zum Beispiel Stahl oder Eisen. Jede Klammer 9 weist eine u-förmige Ausgestaltung unter Bildung eines Stegs 13 und zweier daran angeformter und hinsichtlich ihrer generellen Ausrichtung paralleler Fixierschenkeln 11, 12 auf.Since the frame 5 is in the form of sheet metal, each insertion area 10 is in the form of a slot-shaped recess which is laterally delimited by the two adjacent plates 4 . Each bracket 9 is made of a flat and planar sheet metal such as steel or iron. Each clamp 9 has a U-shaped configuration, forming a web 13 and two fixing legs 11, 12 formed thereon and parallel in terms of their general alignment.

Bei den in den Fig. 10 und 11 dargestellten Klammern 9 reduziert sich der Abstand A zwischen den beiden Fixierschenkeln 11, 12 vom freien Ende eines jeden Fixierschenkels 11 bzw. 12 zum Steg 13 hin. Bei der Ausgestaltung nach Fig. 10 erfolgt die Reduzierung des Abstandes A entgegen die Einführrichtung 24 gesehen in dem an die freien Enden der Fixierschenkel 11 und 12 angrenzenden Teilbereich der Innenflächen 22, 23, während die Innenflächen 22, 23 in dem an den Steg 13 angrenzenden Teilbereich parallel verlaufen. In Fig. 11 ist eine umgekehrte Anordnung dargestellt. Hier verlaufen die Innenflächen 22, 23 in dem an die freien Enden angrenzenden Teilbereich zunächst parallel, während die Innenflächen 22, 23 in dem an den Steg 13 angrenzenden Teilbereich entgegen die Einführrichtung 24 gesehen schräg aufeinander zulaufend ausgebildet sind. Wie den Fig. 10 und 11 zu entnehmen ist, sind der jeweilige Einführbereich 10 und die mit diesem Einführbereich 10 zusammenwirkende Klammer 9 korrespondierend ausgebildet.At the in the 10 and 11 brackets 9 shown, the distance A between the two fixing legs 11, 12 is reduced from the free end of each fixing leg 11 or 12 to the web 13. When designing 10 the reduction of the distance A occurs counter to the direction of insertion 24 in the partial area of the inner surfaces 22, 23 adjoining the free ends of the fixing legs 11 and 12, while the inner surfaces 22, 23 run parallel in the partial area adjoining the web 13. In 11 an inverted arrangement is shown. Here the inner surfaces 22, 23 initially run parallel in the partial area adjoining the free ends, while the inner surfaces 22, 23 in the partial area adjoining the web 13 are designed to run obliquely towards one another, viewed counter to the insertion direction 24. Like the 10 and 11 it can be seen that the respective insertion area 10 and the clip 9 that interacts with this insertion area 10 are designed to correspond.

Bei der in Fig. 11 dargestellten Ausgestaltung bewirken die entgegen die Einführrichtung 24 gesehen aufeinander zuweisend schräg ausgerichteten Wirkflächen 21, dass zwei angrenzende Rahmensegmente 5a beim Einführen der Klammer 9 in die beiden Einführbereiche 10 gegeneinander gezogen werden.At the in 11 In the configuration shown, the active surfaces 21 , which are oriented obliquely towards one another when viewed counter to the insertion direction 24 , cause two adjacent frame segments 5a to be pulled towards one another when the clip 9 is inserted into the two insertion regions 10 .

Das Zusammenwirken zum einen des Teilbereichs der Klammer 9, in dem die Innenflächen 22, 23 parallel verlaufen, und zum anderen des Teilbereichs des Einführbereichs 10, in dem die Wirkflächen 21 parallel verlaufen, verhindert ein unbeabsichtigtes Lösen der Klammer 9.The interaction of the partial area of the clip 9, in which the inner surfaces 22, 23 run parallel, on the one hand, and the partial area of the insertion area 10, in which the active surfaces 21 run parallel, on the other hand, prevents the clip 9 from being unintentionally released.

Zur Erleichterung des Einführens der Fixierschenkel 11, 12 in den jeweiligen Einführbereich 10 können die Innenflächen 22, 23 in dem an die freien Enden der Fixierschenkel 11 und 12 angrenzenden Teilbereich - so wie es in Fig. 10 dargestellt ist - entgegen die Einführrichtung 24 gesehen aufeinander zuweisend schräg ausgerichtet sein und/oder die Wirkflächen 21 - so wie es in Fig. 11 dargestellt ist - entgegen die Einführrichtung 24 gesehen aufeinander zuweisend schräg ausgerichtet sein.To facilitate the insertion of the fixing legs 11, 12 into the respective insertion area 10, the inner surfaces 22, 23 in the partial area adjacent to the free ends of the fixing legs 11 and 12 - as shown in 10 is shown - viewed against the direction of insertion 24 facing each other obliquely and / or the active surfaces 21 - as it is in 11 is shown - be aligned opposite to the insertion direction 24 facing each other obliquely.

Wie beispielsweise den Fig. 1 und 2 zu entnehmen ist, steht die Klammer 9 im fixierten Zustand nicht seitlich gegenüber der Außenkontur des Rahmens 5 hervor. Dies ist darin begründet, dass die beiden aneinander grenzenden Rahmensegmente 5a einen gemeinsamen Aufnahmebereich 18 bilden, in dem sich in der Fixierposition der Klammer 9 der Steg 13 der Klammer 9 befindet.Like the Figures 1 and 2 can be seen, the clip 9 does not protrude laterally in relation to the outer contour of the frame 5 in the fixed state. The reason for this is that the two adjacent frame segments 5a form a common receiving area 18 in which the web 13 of the clamp 9 is located when the clamp 9 is in the fixing position.

Bei dem Ausführungsbeispiel nach den Fig. 5 bis 8 weist einer der beiden Rahmensegmente 5a zweier aneinandergrenzender Rahmensegmente 5a in seinem Endbereich zumindest einen in Richtung des Endbereichs des zweiten Rahmensegmentes 5a weisenden Vorsprung 14 auf. Der mit dem besagten Endbereich des ersten Rahmensegmentes 5a zusammenwirkende Endbereich des zweiten Rahmensegments 5a weist einen mit dem Vorsprung 14 korrespondierenden Aufnahmebereich 15 auf, so dass bei einem Eingriff des Vorsprungs 14 in den korrespondierenden Aufnahmebereich 15 eine Verlagerung der beiden aneinandergrenzenden Rahmensegmente 5a orthogonal zur Blockierrichtung 8 der beiden, durch die Klammer 9 fixierten Enden der Rahmensegmente 5a verhindert ist.In the embodiment according to the Figures 5 to 8 one of the two frame segments 5a of two adjacent frame segments 5a has in its end area at least one projection 14 pointing in the direction of the end area of the second frame segment 5a. The end region of the second frame segment 5a that interacts with said end region of the first frame segment 5a has a receiving region 15 that corresponds to the projection 14, so that when the projection 14 engages in the corresponding receiving region 15, the two adjoining frame segments 5a are displaced orthogonally to the blocking direction 8 of the two ends of the frame segments 5a fixed by the clamp 9 is prevented.

Die beispielsweise in Fig. 5 dargestellte Ausgestaltung ermöglicht eine "Blockmontage" des Einbausatzes. Der Einbausatz besteht aus vier Blöcken. Jeder Block wiederum besteht aus einem Rahmensegment 5a und mehreren Plattensegmenten 4a. Das Rahmensegment 5a und die Plattensegmente 4a eines Blockes sind in dem am Gehäuse 1 angelegten Zustand jeweils mit wenigstens der Hälfte ihrer Fläche aneinander anliegend angeordnet. Vor dem Anlegen eines Blockes an die Außenseite des Gehäuses 1 werden das Rahmensegment 5a und die Plattensegmente 4a dieses Blockes untereinander durch Verschrauben fixiert. Die Anzahl und die Anordnung des Rahmensegments 5a und der Plattensegmente 4a ist bei allen vier Blöcken gleich. Das Gehäuse 1 weist einen rechteckigen Querschnitt auf und die jeweiligen zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a sind im Bereich einer der vier Ecken des Gehäuses 1 angeordnet. Nach der Herstellung der vier Blöcke werden die Blöcke so außenseitig an das Gehäuse 1 angelegt, dass die zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a durch jeweils ein Fixierelement fixiert sind. Die Blöcke können vorgefertigt an die Baustelle geliefert und vor Ort in der vorbeschriebenen Weise zur Bildung eines Einbausatzes montiert werden.The example in figure 5 shown embodiment allows a "block assembly" of the kit. The installation kit consists of four blocks. Each block in turn consists of a frame segment 5a and several plate segments 4a. The frame segment 5a and the plate segments 4a of a block are arranged in contact with the housing 1 with at least half of their area lying against each other. Before applying a block to the outside of the housing 1, the frame segment 5a and the plate segments 4a of this block are fixed to one another by screwing. The number and arrangement of the frame segment 5a and the plate segments 4a is the same for all four blocks. The housing 1 has a rectangular cross-section and the respective cooperating end regions of two adjacent frame segments 5a are arranged in the region of one of the four corners of the housing 1. After making the four Blocks are placed on the outside of the housing 1 in such a way that the interacting end regions of two adjacent frame segments 5a are each fixed by a fixing element. The blocks can be delivered to the site prefabricated and assembled on site in the manner previously described to form a kit.

Wie beispielsweise in den Figuren 2 oder 4 zu erkennen ist, kann der Rahmen 5 im montierten Zustand die gleichen Abmessungen wie die beiden unmittelbar angrenzenden Platten 4 aufweisen. Damit sind der Rahmen 5 und auch die Klammern 9 durch die angrenzenden Platten 4 beispielsweise gegen hohe Temperaturen besser geschützt.As for example in the figures 2 or 4 can be seen, the frame 5 can have the same dimensions as the two immediately adjacent panels 4 in the assembled state. The frame 5 and also the brackets 9 are thus better protected by the adjoining plates 4 against high temperatures, for example.

Bei den Ausführungsbeispielen beispielsweise nach Fig. 2 weisen der Rahmen 5 und die beiden Klammern 9 dieses Rahmens 5 die gleiche Dicke auf. Die beiden Rahmensegmente 5a dieses Rahmens 5 und die beiden Klammern 9 bilden insoweit ein ebenes und recht dünnes Bauteil. Damit ist jede Klammer 9 im eingeführten Zustand mit den beiden angrenzenden Platten 4 in Kontakt und wird durch diese durch Klemmung gegen ein unbeabsichtigtes Herausfallen gesichert.In the exemplary embodiments, for example 2 the frame 5 and the two brackets 9 of this frame 5 have the same thickness. To this extent, the two frame segments 5a of this frame 5 and the two brackets 9 form a flat and very thin component. In this way, each clip 9 is in contact with the two adjoining plates 4 in the inserted state and is secured by clamping against accidental falling out.

Wie beispielsweise in Fig. 2 zu erkennen ist, können in dem Einbausatz Bohrungen 16 vorgesehen sein, durch die Schrauben eingeschraubt sein können. Die Schrauben 17 können dem Zweck dienen, die Platten 4 und den Rahmen 5 untereinander zu verschrauben. Die Schrauben können auch zur Befestigung der Brandschutzklappe in einem Durchbruch einer nicht dargestellten Wand dienen. Die Stoßkanten benachbarter Platten 4 und des Rahmens 5 können miteinander fluchten oder versetzt zueinander angeordnet sein.As for example in 2 can be seen, holes 16 can be provided in the installation kit, can be screwed through the screws. The screws 17 can serve the purpose of screwing the plates 4 and the frame 5 together. The screws can also be used to attach the fire damper in an opening in a wall, not shown. The abutting edges of adjacent panels 4 and of the frame 5 can be aligned with one another or offset from one another.

Die erfindungsgemäße Brandschutzklappe erlaubt eine einfache Montage. So muss in Abhängigkeit von der Anzahl an gewünschten Platten 4 lediglich die hierzu erforderliche Anzahl an Plattensegmenten 4a um das Gehäuse 1 herumgelegt und die Plattensegmente 4a jeder Platte 4 gegeneinander fixiert werden. Anschließend werden an der gewünschten Stelle die Rahmensegmente 5a für den Rahmen 5 um das Gehäuse 1 herumgelegt. Mittels der Klammern 9 werden die angrenzenden Plattensegmente 5a fixiert. Nach erfolgter Fertigstellung des Einbausatzes kann die Brandschutzklappe eingebaut werden. Alternativ ist die anhand von Fig. 5 erläuterte Blockmontage möglich.The fire damper according to the invention allows for easy assembly. Depending on the number of plates 4 desired, only the number of plate segments 4a required for this purpose has to be placed around the housing 1 and the plate segments 4a of each plate 4 fixed against one another. The frame segments 5a for the frame 5 are then placed around the housing 1 at the desired location. Using the brackets 9 the adjacent plate segments 5a are fixed. Once the installation kit has been completed, the fire damper can be installed. Alternatively, the basis of figure 5 explained block assembly possible.

Um ein unbeabsichtigtes Lösen des Einbausatzes zu vermeiden, bietet es sich bei einer Ausgestaltung des Rahmens 5 beispielsweise nach den Fig. 7 oder 9 an, wenn der Einbausatz zumindest zwei entsprechende Rahmen 5 aufweist, wobei zwei Rahmen 5 spiegelverkehrt zueinander angeordnet sind, d.h. die Anordnung der Endbereiche der betreffenden Rahmensegmente 5a und der Klammern 9 dieser beiden Rahmen 5 in Strömungsrichtung 20 gesehen nicht miteinander fluchtend angeordnet sind.In order to avoid unintentional loosening of the installation kit, it is possible to design the frame 5 according to, for example, 7 or 9 when the installation kit has at least two corresponding frames 5, with two frames 5 being arranged mirror-inverted to one another, ie the arrangement of the end regions of the relevant frame segments 5a and the brackets 9 of these two frames 5 are not arranged in alignment with one another as seen in the direction of flow 20.

In den Fig. 10 und 11 ist nochmals das Wirkprinzip eines Fixierelementes dargestellt. Die Rahmensegmente 5a weisen jeweils einen von außen seitlich zugänglichen Einführbereich 10 auf. Jedes Rahmensegment 5a hat eine Wirkfläche 21, die sich von dem freien Ende des betreffenden Fixierschenkels 11 bzw. 12 bis zum Steg 13 erstreckt. In der Fixierposition des jeweiligen Fixierelementes wirkt die Wirkfläche 21 mit dem korrespondierenden Bereich, d.h. der Wirkfläche 22 bzw. 23, des Fixierelementes zusammen. In Fig. 10 ist das Fixierelement als u-förmige Klammer 9 ausgebildet. Die beiden Wirkflächen 21 der zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a weisen voneinander weg und sind - wenn die zusammenwirkenden Endbereiche der beiden angrenzenden Rahmensegmente 5a in Kontakt sind, - in einem Abstand B zueinander angeordnet.In the 10 and 11 the operating principle of a fixing element is shown again. The frame segments 5a each have an insertion area 10 that is laterally accessible from the outside. Each frame segment 5a has an active surface 21 which extends from the free end of the relevant fixing leg 11 or 12 to the web 13. In the fixing position of the respective fixing element, the active surface 21 interacts with the corresponding area, ie the active surface 22 or 23, of the fixing element. In 10 the fixing element is designed as a U-shaped bracket 9 . The two effective surfaces 21 of the cooperating end regions of two adjacent frame segments 5a point away from one another and are arranged at a distance B from one another--if the cooperating end regions of the two adjacent frame segments 5a are in contact.

Der Einfachheit halber sind in Fig. 11 zwei denkbare Ausgestaltungen eines separaten Fixierelementes dargestellt. Das obere Fixierelement ist als eine Art Drahtklammer ausgebildet, die eine ovale Form aufweist und im Bereich einer ihrer beiden Längsseiten unter Bildung zweier freier Enden unterbrochen ist. Darunter ist ein als u-förmig ausgebildete Klammer 9 ausgebildetes Fixierelement dargestellt.For the sake of simplicity, in 11 two possible configurations of a separate fixing element are shown. The upper fixing element is designed as a kind of wire clip, which has an oval shape and is interrupted in the area of one of its two long sides, forming two free ends. A fixing element designed as a U-shaped clamp 9 is shown underneath.

Bei dem Fixierelement, das als eine Art Drahtklammer ausgebildet ist, sind die beiden freien Enden in einem Abstand A zueinander angeordnet. Die Drahtklammer ist vorzugsweise so ausgestaltet, dass sie gegen eine Rückstellkraft ein wenig aufgeweitet werden kann. Im fixierten Zustand greift das eine freie Ende der Klammer in den Einführbereich 10 des einen Rahmensegmentes 5a und das andere freie Ende der Klammer in den Einführbereich 10 des anderen Rahmensegmentes 5a ein. Wenn die zusammenwirkenden Endbereiche der beiden angrenzenden Rahmensegmente 5a, so wie es beispielsweise in Fig. 11 dargestellt ist, in Kontakt mit der jeweiligen Wirkfläche 21 sind, ist bei dem in der Fixierposition befindlichen Fixierelement der Abstand A maximal so groß wie der Abstand B. Damit werden die Rahmensegmente 5a durch das Fixierelement, wenn es sich in seiner Fixierposition befindet, gegeneinander gezogen.In the case of the fixing element, which is designed as a type of wire clip, the two free ends are arranged at a distance A from one another. The wire clip is preferably designed in such a way that it can be expanded a little against a restoring force. In the fixed state, one free end of the clip engages in the insertion area 10 of one frame segment 5a and the other free end of the clip engages in the insertion area 10 of the other frame segment 5a. If the cooperating end regions of the two adjacent frame segments 5a, as is the case for example in 11 is shown, are in contact with the respective active surface 21, with the fixing element in the fixing position, the distance A is at most as large as the distance B. The frame segments 5a are thus pulled against one another by the fixing element when it is in its fixing position .

Bei dem Fixierelement, das als u-förmig ausgebildete Klammer 9 ausgebildet ist und beispielsweise in den Fig. 10 und 11 dargestellt ist, greift im fixierten Zustand der erste Fixierschenkel 11 in den Einführbereich 10 des einen Rahmensegmentes 5a und der zweite Fixierschenkel 12 in den Einführbereich 10 des anderen Rahmensegmentes 5a hinein. Bei der Klammer 9 reduziert sich der Abstand A entgegen die Einführrichtung 24 gesehen in einem Teilbereich zwischen den in dem betreffenden Teilbereich beiden aufeinander zuweisenden und schräg ausgerichteten Innenflächen 22, 23 der Fixierschenkeln 11, 12 vom freien Ende eines jeden Fixierschenkels 11 bzw. 12 zum Steg 13 hin. Jeder Einführbereich 10 weist eine Wirkfläche 21 auf, wobei die Wirkflächen 21 der zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a im fixierten Zustand voneinander wegweisen und in einem Abstand B zueinander angeordnet sind. Die beiden Wirkflächen 21 der zusammenwirkenden Endbereiche der zwei angrenzenden Rahmensegmente 5a sind ebenfalls in einem Teilbereich schräg ausgerichtet.In the fixing element, which is designed as a U-shaped bracket 9 and, for example, in the 10 and 11 is shown, in the fixed state the first fixing leg 11 engages in the insertion area 10 of one frame segment 5a and the second fixing leg 12 in the insertion area 10 of the other frame segment 5a. In the case of the clamp 9, the distance A, viewed counter to the direction of insertion 24, is reduced in a partial area between the two inner surfaces 22, 23 of the fixing legs 11, 12, which face one another and are oriented at an angle in the relevant partial area, from the free end of each fixing leg 11 or 12 to the web 13 towards Each insertion area 10 has an active surface 21, the active surfaces 21 of the interacting end regions of two adjacent frame segments 5a pointing away from one another in the fixed state and being arranged at a distance B from one another. The two effective surfaces 21 of the interacting end areas of the two adjacent frame segments 5a are also aligned obliquely in a partial area.

Beim Einführen der Klammer 9 in Einführrichtung 24 in seine Fixierposition drücken bei der Ausgestaltung nach Fig. 10 die schräg ausgerichteten Innenflächen 22, 23 der Fixierschenkeln 11, 12 auf die Wirkflächen 21 der zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a, so dass die zwei angrenzenden Rahmensegmente 5a gegeneinander gezogen werden. Bei der Ausgestaltung nach Fig. 11 bewirken die schrägen Wirkflächen 21 der zusammenwirkenden Endbereiche zweier angrenzender Rahmensegmente 5a, dass die Rahmensegmente 5a beim Einführen der Klammer 9 aufeinander zu bewegt werden.When inserting the clip 9 in the insertion direction 24 into its fixing position, the design pushes down 10 the obliquely aligned inner surfaces 22, 23 of the fixing legs 11, 12 on the active surfaces 21 of the cooperating end regions of two adjacent frame segments 5a, so that the two adjacent frame segments 5a are pulled towards one another. When designing 11 cause the inclined active surfaces 21 of the cooperating end regions of two adjoining frame segments 5a, that the frame segments 5a are moved towards one another when the clamp 9 is inserted.
