Definitions
- the invention relates to a Feuerschutzabchluss and / or Rauchschutzab gleich for closing a cross section of a building, consisting of a plate-shaped closure element, which consists at least partially of glass, preferably a fire protection glass, and a mecanicelememt enclosing frame which is krafstchlüssig connected to a building part.
- Such a fire protection is, for example, from the DE 196 35 409 A1 known.
- the closing element consists of a pane of fire-resistant glass, which is encircled by a cross-sectionally U-shaped metal profile. At this metal profile, the hinges for mounting the door leaf and also the handle set and a possible door closer are attached.
- the revolving, sturdy metallic U-profile has the output to prevent uncontrolled or excessive discarding of the door in case of fire. Only through the interaction of the enclosing profile of the end element and the equally solid executed steel frame, the fire protection is to fulfill its protective function even in case of fire, which is precisely defined in the provisions of EN 1363-1 and EN 1634 Part 1.
- the thickness of the frame elements is usually several times greater than the thickness of the fire-resistant glazing.
- a metallic, d.b. more opaque, frame in a glass door at all as disturbing, since often the character of a "glass door” is desired.
- the invention is based on the object to provide a fire protection, in which the final element to the highest possible proportion, preferably even completely made of fire-resistant glass, without the risk of uncontrolled distortion of the matters exists in case of fire, thereby jeopardizing compliance with fire protection standards could be.
- the cover is provided on both sides next to the receiving groove for the fire protection strip with a parallel extending retaining groove for receiving a respective holding portion of an elastic sealing profile, the spans the fire protection strip.
- the end of the end element comes to rest.
- the frame in particular the base profile, is provided on the side facing the building part with a receiving groove for receiving a fire protection strip.
- the foaming that occurs then leads to an automatic sealing of the gap area between the frame and the building part, even if this gap area has an irregular shape and size.
- the closing element essentially consists entirely of fire protection glass or is an all-glass door leaf.
- the definition of the terms "complete” or “all-glass” is not intended in the context of this application to preclude the fact that on the one hand functional parts such as handle set, bands or Door closers are made of metallic materials or frontal surfaces of the fire glass, for example by means of film strips or thin metal strips are sealed to protect against environmental influences sensitive sodium silicate, which is in the usual Feuerscbutzverglasung between the individual glass layers, from contact with air and water.
- the idea can additionally be used, the existing in conventional fire protection statements in the edge region of the closure element and thus movable, frame-like reinforcements in the frame, i. a stationary component, to relocate. In the resting state of the stabilizing agent, these are not within the cross section of the terminating element and therefore do not affect its appearance in any way.
- a fire protection according to the invention it is therefore possible to make the end element completely made of fire-resistant glass, of course, the handle set or bands for the storage of the end element or a door closer and a lower smoke protection seal continue to be made of metal.
- the stabilizers only then come into action and are only visible when the fire actually occurs. Only in this case, stabilizing agents are needed in the edge region of the end element, as in the normal operating state, the strength of a glass entire closure element is quite given, such as glass doors in the normal version, ie without fire protection function, have proven for some time.
- the stabilization Exxungsmittel are arranged outside the visible cross section of the closure element, if they have to fulfill any function, whereas in the known fire protection statements stabilizing means, for example in the form of rotating frame elements are always firmly connected to the closing element and therefore the optics in not affect negligibly.
- the frame as a location for the stabilizer in the non-active state is a particularly advantageous place, as there is usually sufficient space available to accommodate the stabilizing agent including its self-acting drive, without the optical properties of the frame are adversely affected ,
- these sunk, ie, for example, completely plastered, installed so that when using a glass whole closure element no metal parts are more visible to the viewer when the final element, for example, between opposite walls and between the ceiling and floor of a Flures extends and the frame is flush-mounted in walls, ceiling and floor or plaster or floor covering.
- the stabilizing agents are within the limited by the frame cross-section that the edge regions of the end element can support and thereby prevent excessive distortion of the same and resulting flame passage safely.
- the stabilizing function is particularly good when the terminating element is bilateral, i. from its two sides of Stabilmaschinesffenn supportable. Also, the stabilizing means should extend in an elongated manner parallel to the end faces of the closing element, in order to enable the widest possible and not only selective support in case of fire.
- the stabilizing agents contain an activatable heat-activatable intumescent, in particular sodium silicate.
- an activatable heat-activatable intumescent in particular sodium silicate.
- the invention further ausgestaltend is provided that the stabilizing agent at least one stabilization profile, in particular a. Have steel profile. In this way, a very high strength of the stabilizing agent is achieved, so that even very large internal deformation forces of the closing element , especially in very uneven exposure to heat, can be supported.
- the stabilizing agents are formed by a hollow profile filled with an intumescent agent, which has an opening facing away from the direction of movement of the stabilizing agent.
- an intumescent agent which has an opening facing away from the direction of movement of the stabilizing agent.
- the stabilization profile is slidably mounted in a guide profile, wherein the guide profile and / or the stabilization profile have stop means which define a Stabilisiergswolf in which the stabilization profile has emerged maximally from the frame.
- stabilization profiles and the guide profiles thus act together according to the telescopic principle, which allows the absorption of transverse forces, in particular even in the extended state.
- the stabilization profile is U-shaped in cross-section with feet projecting outwards at the ends of its legs and the guide profile is formed inverted in a U-shaped cross-section with hooks projecting inwards at the ends of its legs.
- two guide profiles are combined to form a base profile and that a stiffening profile is arranged between the guide profiles.
- the latter has the task of ensuring the rigidity of the frame construction, in particular to absorb the forces that are caused by the bands movable, for example, tiltable, pivotal or hinged mounted end elements to accommodate.
- the base profile consisting of a lower part, which has the opposite legs of the two guide profiles, and a non-positively connected, in particular welded, upper part, which has the mutually facing legs of the two guide profiles.
- the frame has a cover, which covers the stabilization profiles and / or the guide profiles and with predetermined breaking points is provided, which limit an opening area, which can be lifted by the swelling Dämm Anlagen briefly.
- the inherent stabilization function for the edge regions of the end element is not to be considered.
- the places where the stabilization profiles emerge in case of fire, can be made completely invisible, so that such a frame can also meet very high aesthetic requirements. Only in case of fire, the cover profile of such a frame breaks exactly at the points from which emerge the stabilization profiles.
- the material thickness in the area of the predetermined breaking points and the quantity and type of intumescent agent must be coordinated in such a way that a secure emergence of the stabilization profiles is ensured.
- the cover profile is connected to a holding profile, preferably via latching lugs, and the stiffening profile is arranged between the holding profile and the cover profile, this results in a very space-saving positioning of the stiffening profile between the mutually parallel stabilization profiles together with the associated guide profiles.
- Fig. 1 shows a view of a fire protection cover 1 in the form of a glass door, consisting of a closing element 2 in the form of a door leaf, which consists of a holding set 4 in addition to a handle set 3, bearing pin 4a and a door closer 5 completely made of a fire-resistant glass of known type, and a frame. 6 , which is non-positively, in particular by means of screws, connected to a building part 7 in the form of a wall.
- the frame 6 is substantially complete by one on the building part 7 after the Zargeneinbau applied plaster layer P covered and runs along the two vertical end faces of the door panel and at least along the horizontal upper end side, if necessary, the horizontal lower, ie would then be embedded in the floor.
- the frame has a base profile 8, which consists of steel and is designed in two layers in its central region 9, because there are an upper part 10 and a lower part 11 of the base profile 8, for example, connected by welding. Alternatively, however, is also a one-piece design of the base profile 8 into consideration.
- Upper part 10 and lower part 11 of the base profile 8 together form two guide profiles 12, which are arranged on both sides of the central region 9.
- the guide profiles 12 have in cross section the shape of a U and have at the ends of their legs 13 each inwardly projecting feet 14, which take over the function of stop means.
- a stabilizing profile 15 is arranged, which also consists of steel and is U-shaped in cross section, wherein the two U-sections of the guide profiles 12 and the stabilizing profiles 15 are arranged rotated by 180 ° to each other.
- At the ends of the legs 16 of the stabilizing profiles 15 outwardly projecting hooks 17 are arranged. The hooks 17 prevent the stabilization profiles 15 from escaping from the guide profiles 12 and cause a limitation of a relative movement of guide profiles 12 and stabilization profiles 15 to each other.
- the stabilization profiles 15 are substantially completely filled in their interior with an intumescent agent 18, in particular a sodium silicate, which swells up under the influence of heat.
- an intumescent agent 18 in particular a sodium silicate, which swells up under the influence of heat.

- the cover 21 is connected in its central region 22 via recesses 23 with locking lugs 24 of a retaining profile 25 which extends in the central region of the base profile 8 between the two guide profiles 12.
- the retaining profile 25 also has a U-shape and takes in its interior - limited by the central region 22 of the cover 21 - a stiffening profile 26.
- the stiffening profile 26 is in cross section essentially U-shaped and has in its two edge regions 27 each have a plurality of folded sheet metal layers, whereby the resistance moment can be significantly increased.
- the existing steel reinforcing profile 26 is from the DE 196 51 699 C1 known, so that can be dispensed with further explanations at this point.
- the cover profile 21 has in its two edge regions 29 each opening portions 30 which are connected via predetermined breaking points 31 with the remaining portions of the cover 21.
- the predetermined breaking points. 31 are defined by notches 32, which are introduced from the back of the cover in the surface and therefore are not visible from the outside.
- the cover profile further comprises a flat receiving groove 33 into which a fire protection strip 34 is inserted.
- a fire protection strip 34 In the event of fire, the heat-swelling material of this fire protection strip 34 leads to a seal between the frame 6 and the end face 35 of the end element 2 or its delimiting edge regions of the viewing sides.
- a retaining groove 36 On both sides of the receiving groove 33 is in each case a retaining groove 36, in each of which a holding portion 37 of an elastic material, in particular of silicone elastomer, existing seal 38 is inserted.

- the seal 38 is destroyed at temperatures above 200 ° C, so that the fire protection strip 34 consequently enters the sphere of influence of high temperatures, and then - as already indicated above - takes over a sealing of the gap area against a flame passage.
- the fire protection strip 34 may be covered for reasons of appearance with a thin metal profile having the color of the cover 21. In this way it is prevented that can be looked through the crystal clear material of the seal 38 on the color possibly deviating fire protection strip.
- Fig. 3 shows the fire protection closure 1 in a state in which the left stabilization profile 15 has emerged from the frame 6 after exposure to heat by foaming the intumescent agent 18.
- the swelling Dämm Anlagenslavner acts like a hydraulic drive medium for the "Kobu” in the form of the stabilization profile 15, since the located behind this "cylinder space” is completed and the pressure generated during swelling can be reduced only by displacement of the stabilizing profiles 15 to the outside.
- the cover profile 21 is broken in the region of the left opening area at the predetermined breaking points, 31.
- the on the "hot side” stabilization profiles 15 are located in FIG. 3 In its stabilization position, in which the hooks 17 rest on the legs 14 of the legs 13 of the guide profiles 12, so that a further exit movement of the stabilizing profiles 15 is prevented.
- the stabilizing profile 15 is located within the cross section of the closing element 2 and can therefore be Support edge regions 39 and therefore prevent excessive distortion.

Abstract
Description
Die Erfindung betrifft einen Feuerschutzabchluss und/oder Rauchschutzabschluss zum Verschließen eines Querschnitts eines Gebäudes, bestehend aus einem plattenförmigen Abschlusselement, das zumindest zum Teil aus Glas, vorzugsweise einem Feuerschutzglas, besteht, und einer das Abschlusselememt einfassenden Zarge, die mit einem Gebäudeteil krafstchlüssig verbindbar ist.The invention relates to a Feuerschutzabchluss and / or Rauchschutzabschluss for closing a cross section of a building, consisting of a plate-shaped closure element, which consists at least partially of glass, preferably a fire protection glass, and a Abschlusselememt enclosing frame which is krafstchlüssig connected to a building part.
Ein derartiger Feuerschutzabschluss ist beispielsweise aus der
Als nachteilig ist es bei dem vorgenannten Feuerschutzabschluss aber auch bei allen anderen ähnlich aufgebauten bekannten Feuerschutzabschlüssen anzusehen, dass das Abschlusselement auf Grund des umlaufenden metallischen Rahmens insbesondere architektonischen und ästhetischen Ansprüchen oftmals nicht gerecht werden kann. Zum einen ist die Dicke der Rahmenelemente in der Regel um ein Mehrfaches größer als die Dicke der Feuerschutzverglasung. Zum anderen wird ein metallischer, d.b. undurchsichtiger, Rahmen in einer Glastür überhaupt als störend empfunden, da oftmals der Charakter einer "Ganzglastür" gewünscht wird.It is disadvantageous in the aforementioned Feuerschutzabschluss but also in all other similarly constructed known Feuerschutzabschlüssen that the final element due to the circumferential metallic frame in particular architectural and aesthetic claims often can not do justice. On the one hand, the thickness of the frame elements is usually several times greater than the thickness of the fire-resistant glazing. On the other hand, a metallic, d.b. more opaque, frame in a glass door at all as disturbing, since often the character of a "glass door" is desired.
Das Dokument
Der Erfindung liegt die Aufgabe zu Grunde, einen Feuerschutzabschluss zu schaffen, bei dem das Abschlusselement zu einem möglichst hohen Anteil, vorzugsweise sogar vollständig aus Feuerschutzglas bestehen kann, ohne dass im Brandfall die Gefahr eines unkontrollierten Verziehens des Abschlusslements besteht, wodurch die Einhaltung der Feuerschutznormen gefährdet werden könnte.The invention is based on the object to provide a fire protection, in which the final element to the highest possible proportion, preferably even completely made of fire-resistant glass, without the risk of uncontrolled distortion of the Abschlusslements exists in case of fire, thereby jeopardizing compliance with fire protection standards could be.
Die Aufgabe wird durch den Abschluss gemäss Anspruch 1 gelöst.The object is achieved by the conclusion according to
Um mit dem erfindungsgemäßen Feuerschutzabschluss auf einfache Weise auch den Anforderungen an einen Rauchschutzabschluss gerecht werden zu können, wird vorgeschlagen, dass das Abdeckprofil beidseitig neben der Aufnahmenut für die Brandschutzleiste mit einer parallel hierzu verlaufenden Haltenut zur Aufnahme jeweils eines Halteabschnitts eines elastischen Dichtungsprofils versehen ist, das die Brandschutzleiste überspannt. In einem vorzugsweise gewölbten Mittelbereich dieses elastischen Dichtungsprofils, kommt die Stimseite des Abschlusselements zur Anlage. Hierdurch kann die erforderliche Dichtheit zwischen Abschlusselement und Zarge erreicht werden, die zur Erfüllung der einschlägigen Rauchschutznormen gegeben sein muss.In order to be able to meet the requirements of a Rauchschutzabschluss in a simple manner with the fire protection according to the invention, it is proposed that the cover is provided on both sides next to the receiving groove for the fire protection strip with a parallel extending retaining groove for receiving a respective holding portion of an elastic sealing profile, the spans the fire protection strip. In a preferably curved central region of this elastic sealing profile, the end of the end element comes to rest. As a result, the required tightness between the end element and frame can be achieved, which must be given to meet the relevant smoke protection standards.
Um die Abdichtarbeiten im Bereich zwischen Zarge und dem daran angrenzenden Gebäudeteil zu minimieren, wird vorgeschlagen, dass die Zarge, insbesondere das Basisprofil, an der dem Gebäudeteil zugewandten Seite mit einer Aufnahmenut zur Aufnahme einer Brandschutzleiste versehen ist. Im Brandfall führt die dann eintretende Schaumbildung zu einer automatischen Abdichtung des Spaltbereichs zwischen der Zarge und dem Gebäudeteil, auch wenn dieser Spaltbereich eine unregelmäßige Gestalt und Größe besitzt.In order to minimize the sealing work in the area between the frame and the adjoining building part, it is proposed that the frame, in particular the base profile, is provided on the side facing the building part with a receiving groove for receiving a fire protection strip. In the event of fire, the foaming that occurs then leads to an automatic sealing of the gap area between the frame and the building part, even if this gap area has an irregular shape and size.
Des Weiteren ist noch vorgesehen, dass das Abschlusselement im Wesentlichen vollständig aus Feuerschutzglas besteht bzw. ein Ganzglas-Türblatt ist. Der Definition der Begriffe "vollständig" bzw. "Ganzglas", soll im Rahmen dieser Anmeldung jedoch nicht dem Umstand entgegenstehen, dass einerseits Funktionsteile wie Drückergarnitur, Bänder oder Türschließer aus metallischen Werkstoffen bestehen oder aber stirnseitige Flächen des Feuerschutzglases beispielsweise mittels Folienstreifen oder dünnen Metallstreifen versiegelt sind, um das gegenüber Umwelteinflüssen empfindliche Natriumsilikat, das sich bei üblichen Feuerscbutzverglasung zwischen den einzelnen Glasschichten befindet, vor einem Kontakt mit Luft und Wasser zu schützen.Furthermore, it is also envisaged that the closing element essentially consists entirely of fire protection glass or is an all-glass door leaf. However, the definition of the terms "complete" or "all-glass" is not intended in the context of this application to preclude the fact that on the one hand functional parts such as handle set, bands or Door closers are made of metallic materials or frontal surfaces of the fire glass, for example by means of film strips or thin metal strips are sealed to protect against environmental influences sensitive sodium silicate, which is in the usual Feuerscbutzverglasung between the individual glass layers, from contact with air and water.
Bei der Erfindung kann somit ergänzend die Idee zur Anwendung kommen, die bei herkömmlichen Feuerschutzabschlüssen im Randbereich des Abschlusselements vorhandenen und damit beweglichen, rahmenartigen Verstärkungen in die Zarge, d.h. ein stillstehendes Bauteil, zu verlegen. Im Ruhezustand der Stabilisierungsmittel befinden sich diese nicht innerhalb des Querschnitts des Abschlusselements und beeinträchtigen dessen Optik daher in keiner Weise. Bei einem erfindungsgemäßen Feuerschutzabschluss ist es daher möglich, das Abschlusselement vollständig aus Feuerschutzglas herzustellen, wobei selbstverständlich die Drückergarnitur oder Bänder für die Lagerung des Abschlusselements oder ein Türschließer und eine untere Rauchschutzdichtung weiterhin aus Metall bestehen.In the invention, therefore, the idea can additionally be used, the existing in conventional fire protection statements in the edge region of the closure element and thus movable, frame-like reinforcements in the frame, i. a stationary component, to relocate. In the resting state of the stabilizing agent, these are not within the cross section of the terminating element and therefore do not affect its appearance in any way. In a fire protection according to the invention, it is therefore possible to make the end element completely made of fire-resistant glass, of course, the handle set or bands for the storage of the end element or a door closer and a lower smoke protection seal continue to be made of metal.
Die Stabilisierungsmittel treten erfindungsgemäß erst dann in Aktion und sind auch erst dann sichtbar, wenn tatsächlich der Brandfall eintritt. Nur in diesem Fall werden im Randbereich des Abschlusselements Stabilisierungsmittel benötigt, da im normalen Betriebszustand die Festigkeit eines Ganzglas-Abschlusselements durchaus gegeben ist, wie beispielsweise Ganzglastüren in normaler Ausführung, d.h. ohne Feuerschutzfunktion, seit geraumer Zeit bewiesen haben. Bei einem erfindungsgemäßen Feuerschutzabschluss sind somit die Stabilisxexungsmittel außerhalb des sichtbaren Querschnitts des Abschlusselements angeordnet, wenn sie keine Funktion zu erfüllen haben, wohingegen bei den bekannten Feuerschutzabschlüssen die Stabilisierungsmittel beispielsweise in Form von umlaufenden Rahmenelementen stets fest mit dem Abschlusselement verbunden sind und daher dessen Optik in nicht unbeträchtlicher Weise beeinträchtigen. Die Zarge als Unterbringungsort für die Stabilisierungsmittel im nicht aktiven Zustand ist insofern ein besonders vorteilhafter Ort, als dort in der Regel hinreichend Platz zur Verfügung steht, um die Stabilisierungsmittel einschließlich ihres selbsttätig wirkenden Antriebs unterzubringen, ohne dass die optischen Eigenschaften der Zarge hierdurch nachteilig beeinflusst werden. Bei der Zarge besteht häufig sogar die Möglichkeit, diese versenkt, d.h. beispielsweise vollständig eingeputzt, einzubauen, so dass bei Verwendung eines Ganzglas-Abschlusselements keinerlei Metallteile für den Betrachter mehr sichtbar sind, wenn sich das Abschlusselement beispielsweise zwischen gegenüberliegenden Wänden sowie zwischen Decke und Boden eines Flures erstreckt und die Zarge flächenbündig in Wände, Decke und Boden bzw. Verputz- oder Bodenbelag eingelassen ist.According to the invention, the stabilizers only then come into action and are only visible when the fire actually occurs. Only in this case, stabilizing agents are needed in the edge region of the end element, as in the normal operating state, the strength of a glass entire closure element is quite given, such as glass doors in the normal version, ie without fire protection function, have proven for some time. In a fire protection according to the invention thus the stabilization Exxungsmittel are arranged outside the visible cross section of the closure element, if they have to fulfill any function, whereas in the known fire protection statements stabilizing means, for example in the form of rotating frame elements are always firmly connected to the closing element and therefore the optics in not affect negligibly. The frame as a location for the stabilizer in the non-active state is a particularly advantageous place, as there is usually sufficient space available to accommodate the stabilizing agent including its self-acting drive, without the optical properties of the frame are adversely affected , In the frame often even the possibility of these sunk, ie, for example, completely plastered, installed, so that when using a glass whole closure element no metal parts are more visible to the viewer when the final element, for example, between opposite walls and between the ceiling and floor of a Flures extends and the frame is flush-mounted in walls, ceiling and floor or plaster or floor covering.
Trotz dieser sehr vorteilhaften optischen Eigenschaften des erfindungsgemäßen Feuerschutzabschlusses wird dieser seinen von den einschlägigen Vorschriften geforderten Eigenschaften gleichfalls gerecht. Im Brandfall befinden sich nämlich die Stabilisierungsmittel soweit innerhalb des durch die Zarge begrenzten Querschnitts, dass die Randbereiche des Abschlusselements abstützen können und dadurch einen übermäßigen Verzug der selben sowie daraus resultierenden Flammendurchtritt sicher verhindern können.Despite these very advantageous optical properties of the fire protection according to the invention this will also meet its required by the relevant regulations properties. In case of fire, namely, the stabilizing agents are within the limited by the frame cross-section that the edge regions of the end element can support and thereby prevent excessive distortion of the same and resulting flame passage safely.
Die Stabilisicrungsfunktion ist besonders gut, wenn das Abschlusselement beidseitig, d.h. von seinen beiden Ansichtsseiten von Stabilisierungsmitteln, abstützbar ist. Auch sollten sich die Stabilisierungsmittel langgestreckt parallel zu den Stirnseiten des Abschlusselements erstrecken, um eine möglichst großflächige und nicht nur punktuelle Abstützung im Brandfall zu ermöglichen.The stabilizing function is particularly good when the terminating element is bilateral, i. from its two sides of Stabilisierungsmitteln supportable. Also, the stabilizing means should extend in an elongated manner parallel to the end faces of the closing element, in order to enable the widest possible and not only selective support in case of fire.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Stabilisierungsmittel einen unter Hitzeeinwirkung aktivierbaren Dämmschichtbildner, insbesondere Natriumsilikat, enthalten. Diese im Stand der Technik bereits seit langem bewahrten, im Brandfall aufschäumenden Stoffe, können im aufgeschäumten und unter Hitzeeinwirkung verkrusteten Zustand eine solche Festigkeit aufweisen, dass sie erforderlichen Falls allein die Funktion der Stabilisierungsmittel erfüllen können.According to a particularly advantageous embodiment of the invention, it is provided that the stabilizing agents contain an activatable heat-activatable intumescent, in particular sodium silicate. These substances, which have been preserved for a long time in the state of the art and intumescent in the event of fire, can have such strength in the foamed state which is encrusted by the action of heat that they alone can fulfill the function of the stabilizing agents.
Die Erfindung weiter ausgestaltend ist vorgesehen, dass die Stabilisierungsmittel mindestens ein Stabilisierungsprofil, insbesondere ein. Stahlprofil aufweisen. Auf diese Weise wird eine sehr hohe Festigkeit der Stabilisierungsmittel erreicht, sodass auch sehr große innere Verformungskräfte des Abschlusselements, insbesondere bei sehr ungleichmäßiger Beaufschlagung mit Hitze, abgestützt werden können. The invention further ausgestaltend is provided that the stabilizing agent at least one stabilization profile, in particular a. Have steel profile. In this way, a very high strength of the stabilizing agent is achieved, so that even very large internal deformation forces of the closing element , especially in very uneven exposure to heat, can be supported.
Gemäß einer besonders bevorzugten Ausführungsform sind die Stabilisierungsmittel von einem mit einem Dämmschichtbildner gefüllten Hohlprofil gebildet, das eine der Bewegungsrichtung des Stabilisierungsmittels abgewandte Öffnung besitzt. Beim Aufquellen des Dämmschichtbildners im Brandfall kann der gebildete Schaum, der gegenüber dem Dämmschichtbildner im Ruhezustand ein sehr viel größeres Volumen einnimmt durch die Öffnung austreten und sich an einer geeignete Stützfläche der Zarge abstützen, wodurch das Hohlprofil in den Querschnitt des Abschlusselements vorgeschoben wird. Der "Antrieb" des Stabilisierungsmittels erfolgt somit nach dem "Rückstossprinzip". Die Unterbringung des Dämmschichtbildners, d.h. des Antriebsmaterials des Stabilisierungsmittels, in einem Hohlprofil ermöglicht des Weiteren eine sehr gute Dosierung und eine geschützte, weil abgeschlossene, Unterbringung des Dämmschichtbildners. Durch die Öffnung in dem Hohlprofil lässt sich im Übrigen der Dämmschichtbildner sehr einfach in das Hohlprofil einbringen.According to a particularly preferred embodiment, the stabilizing agents are formed by a hollow profile filled with an intumescent agent, which has an opening facing away from the direction of movement of the stabilizing agent. When swelling the intumescent in case of fire, the foam formed, which occupies a much larger volume compared to the intumescent through the opening and support on a suitable support surface of the frame, whereby the hollow profile is advanced in the cross section of the closure element. The "drive" of the stabilizer thus takes place according to the "Rückstossprinzip". The placement of the intumescent, ie the driving material of the stabilizing agent in a hollow profile further allows a very good dosage and a protected, because completed, housing the intumescent. Through the opening in The hollow profile can be very easily introduced into the hollow profile by the way the Dämmschichtbildner.
Nach der Erfindung wird des Weiteren vorgeschlagen, dass das Stabilisierungsprofil in einem Führungsprofil verschiebbar gelagert ist, wobei das Führungsprofil und/oder das Stabilisierungsprofil Anschlagmittel aufweisen, die eine Stabilisieruttgsstellung definieren, in der das Stabilisierungsprofil maximal aus der Zarge herausgetreten ist.According to the invention, it is further proposed that the stabilization profile is slidably mounted in a guide profile, wherein the guide profile and / or the stabilization profile have stop means which define a Stabilisiergsstellung in which the stabilization profile has emerged maximally from the frame.
Auf diese Weise wird ein unkontrolliert weites Herausfahren der Stabilisierungsprofile verhindert und auch in der Stabilisierungsstellung sichergestellt, dass die Stabilisierungsprofile noch in den Führungsprofilen gehalten sind, und insbesondere seitlich zur Bewegungsrichtung der Stabilisierungsprofile wirkende, von dem Abschlusselement ausgeübte Kräfte aufnehmen können. Die Stabilisierungsprofile und die Führungsprofile wirken somit nach dem Teleskopprinzip zusammen, was insbesondere auch im ausgefahrenen Zustand die Aufnahme von Querkräften erlaubt.In this way, an uncontrolled wide retraction of the stabilization profiles is prevented and also ensured in the stabilization position that the stabilization profiles are still held in the guide profiles, and in particular laterally to the direction of movement of the stabilizing profiles acting, can exert forces exerted by the closing element. The stabilization profiles and the guide profiles thus act together according to the telescopic principle, which allows the absorption of transverse forces, in particular even in the extended state.
Gemäß einer bevorzugten Ausführungsform ist das Stabilisierungsprofil im Querschnitt U-förmig mit an den Enden seiner Schenkel nach außenstehenden Füßen ausgebildet und das Führungsprofil im Querschnitt umgekehrt U-förmig mit an den Enden seiner Schenkel nach innen vorstehenden Haken ausgebildet. Durch einfache Umformbearbeitung, wie beispielsweise Biegen oder Strangpressen, lassen sich auf diese Weise wirksame Anschlagmittel zur Begrenzung der Austrittsbewegung der Stabilisierungsprofile herstellen.According to a preferred embodiment, the stabilization profile is U-shaped in cross-section with feet projecting outwards at the ends of its legs and the guide profile is formed inverted in a U-shaped cross-section with hooks projecting inwards at the ends of its legs. By simple forming processing, such as bending or extrusion, can be produced in this way effective stop means for limiting the exit movement of the stabilization profiles.
Zur Reduzierung des Herstellungsaufwandes wird vorgeschlagen, dass zwei Führungsprofile zu einem Basisprofil zusammengefasst sind und dass zwischen den Führungsprofilen ein Versteifungsprofil angeordnet ist. Letzteres hat die Aufgabe, die Steifigkeit der Zargenkonstruktion zu gewährleisten, insbesondere die Kräfte aufzunehmen, die durch die Bänder beweglich, beispielsweise kippbar, schwenkbar oder klappbar gelagerte Abschlusselemente hervorgerufen werden aufzunehmen.To reduce the production costs, it is proposed that two guide profiles are combined to form a base profile and that a stiffening profile is arranged between the guide profiles. The latter has the task of ensuring the rigidity of the frame construction, in particular to absorb the forces that are caused by the bands movable, for example, tiltable, pivotal or hinged mounted end elements to accommodate.
Es ist ferner möglich, dass das Basisprofil, aus einem Unterteil, das die voneinander abgewandten Schenkel der beiden Führungsprofile aufweist, und einem damit kraftschlüssig verbundenen, insbesondere verschweißten, Oberteil besteht, das die aufeinander zugewandten Schenkel der beiden Führungsprofile aufweist.It is also possible that the base profile, consisting of a lower part, which has the opposite legs of the two guide profiles, and a non-positively connected, in particular welded, upper part, which has the mutually facing legs of the two guide profiles.
Ferner ist nach der Erfindung noch vorgesehen, dass die Zarge ein Abdeckprofil aufweist, das die Stabilisierungsprofile und/oder die Führungsprofile überdeckt und das mit Sollbruchstellen versehen ist, die einen Öffnungsbereich begrenzen, der durch den aufquellenden Dämmschichtbildner abhebbar ist. Im nichtaktivierten Zustand der Stabilisierungsprofile ist der Zarge bei einer derartigen Ausgestaltung die ihr inne wohnende Stabilisierungsfunktion für die Randbereiche des Abschlusselements überhaupt nicht anzusehen. Die Stellen an denen die Stabilisierungsprofile im Brandfall austreten, können völlig unsichtbar gestaltet werden, so dass eine derartige Zarge auch sehr hohen ästhetischen Anforderungen gerecht werden kann. Erst im Brandfall bricht das Abdeckprofil einer derartigen Zarge genau an den Stellen auf, aus denen die Stabilisierungsprofile hervortreten. Die Materialstärke im Bereich der Sollbruchstellen und die Menge und die Art des Dämmschichtbildners sind selbstverständlich so abzustimmen, dass ein sicheres Hervortreten der Stabilisierungsprofile gewährleistet ist.It is also provided according to the invention that the frame has a cover, which covers the stabilization profiles and / or the guide profiles and with predetermined breaking points is provided, which limit an opening area, which can be lifted by the swelling Dämmschichtbildner. In the non-activated state of the stabilization profiles of the frame in such an embodiment, the inherent stabilization function for the edge regions of the end element is not to be considered. The places where the stabilization profiles emerge in case of fire, can be made completely invisible, so that such a frame can also meet very high aesthetic requirements. Only in case of fire, the cover profile of such a frame breaks exactly at the points from which emerge the stabilization profiles. Of course, the material thickness in the area of the predetermined breaking points and the quantity and type of intumescent agent must be coordinated in such a way that a secure emergence of the stabilization profiles is ensured.
Wenn das Abdeckprofil mit einem Halteprofil, vorzugsweise über Rastnasen, verbunden ist und das Versteifungsprofil zwischen dem Halteprofil und dem Abdeckprofil angeordnet ist, ergibt sich hiermit eine sehr platzsparende Positionierung des Versteifungsprofils zwischen den parallel zueinander verlaufenden Stabilisierungsprofilen nebst den zugeordneten Führungsprofilen.If the cover profile is connected to a holding profile, preferably via latching lugs, and the stiffening profile is arranged between the holding profile and the cover profile, this results in a very space-saving positioning of the stiffening profile between the mutually parallel stabilization profiles together with the associated guide profiles.

Aus
In jedem Führungsprofil 12 ist ein Stabilisierungsprofil 15 angeordnet, das ebenfalls aus Stahl besteht und im Querschnitt U-förmig ist, wobei die beiden U-Querschnitte der Führungsprofile 12 und der Stabilisierungsprofile 15 um 180° zu einander verdreht angeordnet sind. An Enden der Schenkel 16 der Stabilisierungsprofile 15 sind nach außen vorstehende Haken 17 angeordnet. Die Haken 17 verhindern, dass die Stabilisierungsprofile 15 aus den Führungsprofilen 12 austreten können und bewirken eine Begrenzung einer Relativbewegung von Führungsprofilen 12 und Stabilisierungsprofilen 15 zueinander.In each
Die Stabilisierungsprofile 15 sind in ihrem Innern im Wesentlichen vollständig mit einem unter Hitzeeinwirkung aufquellenden Dämmschichtbildner 18, insbesondere einem Natriumsilikat, gefüllt.The stabilization profiles 15 are substantially completely filled in their interior with an
In dem Unterteil 11 des Basisprofils 8 befindet sich eine Aufnahmenut 19, in die eine Brandschutzleiste 20 eingelegt ist. Die Brandschutzleiste 20 besteht ebenfalls aus einem unter Hitzeeinwirkung aufquellenden Dämmschichtbildner, beispielsweise Natriumsilikat.In the
Das Basisprofil 8 wird von einem Abdeckprofil 21 umfasst, das im Querschnitt eine flache U-Form besitzt. Das Abdeckprofil 21 ist in seinem Mittelbereich 22 über Rücksprünge 23 mit Rastnasen 24 eines Halteprofils 25 verbunden, das sich im Mittelbereich des Basisprofils 8 zwischen den beiden Führungsprofilen 12 erstreckt. Das Halteprofil 25 besitzt ebenfalls eine U-Form und nimmt in seinem Innern - begrenzt durch den Mittelbereich 22 des Abdeckprofils 21 - ein Versteifungsprofil 26 auf. Das Versteifungsprofil 26 ist im Querschnitt im Wesentlichen U-förmig und besitzt in seinen beiden Randbereichen 27 jeweils eine Mehrzahl übereinander gefalteter Blechlagen, wodurch das Widerstandsmoment deutlich gesteigert werden kann. Das aus Stahl bestehende Versteifungsprofil 26 ist aus der
Im Bereich der Übergänge zwischen den vertikalen und den horizontalen Abschnitten der Zarge 6 befinden sich rechtwinklige Eckverbinder 28, die in diesen Bereichen für die notwendige Steifigkeit und Winkligkeit der Zargenkonstruktion sorgen.In the region of the transitions between the vertical and the horizontal sections of the
Das Abdeckprofil 21 weist in seinen beiden Randbereichen 29 jeweils Öffnungsbereiche 30 auf, die über Sollbruchstellen 31 mit den übrigen Abschnitten des Abdeckprofils 21 verbunden sind. Die Sollbruchstellen. 31 sind durch Einkerbungen 32 definiert, die von der Rückseite des Abdeckprofils in dessen Oberfläche eingebracht sind und daher von außen nicht sichtbar sind.The
Im Mittelbereich 22 weist das Abdeckprofil des Weiteren eine flache Aufnahmenut 33 auf, in die eine Brandschutzleiste 34 eingelegt ist. Im Brandfall führt das unter Hitzeeinwirkung aufquellende Material dieser Brandschutzleiste 34 zu einer Abdichtung zwischen der Zarge 6 und der Stimseite 35 des Abschlusselements 2 bzw. dessen abgrenzenden Randbereichen der Ansichtsseiten.In the middle region 22, the cover profile further comprises a
Beidseitig der Aufnahmenut 33 befindet sich jeweils eine Haltenut 36, in die jeweils ein Halteabschnitt 37 einer aus elastischem Material, insbesondere aus Silikonelastomer, bestehenden Dichtung 38 eingesetzt ist. Die Dichtung 38 überspannt die Brandschutzleiste 34 und sorgt auch im "kalten Zustand" für eine Abdichtung zwischen der Stirnseite 35 des Abschlusselements 2 und der Zarge 6, so dass der Feuerschutzabschluss 1 auch den einschlägigen Rauchschutznormen genügt. Im Brandfall wird die Dichtung 38 bei Temperaturen oberhalb von 200° C zerstört, so dass die Brandschutzleiste 34 infolgedessen in den Einflussbereich hoher Temperaturen gelangt, und dann- wie bereits zuvor angedeutet - eine Abdichtung des Spaltbereichs gegen einen Flammendurchtritt übernimmt. Die Brandschutzleiste 34 kann aus optischen Gründen mit einem dünnen Metallprofil überdeckt sein, das die Farbe des Abdeckprofils 21 aufweist. Auf diese Weise wird verhindert, dass durch das glasklare Material der Dichtung 38 auf die farblich eventuell abweichende Brandschutzleiste geblickt werden kann.On both sides of the receiving
