Abstract

The profile i.e. door leaf frame (100), has an isolation rod (3) connected with outer profile parts (1, 2) i.e. aluminum profiles. An outer profile part connection element (5) connects the profile parts. The connection element is arranged in an intermediate space (4) such that the connection element is spaced from profile parts. A positioning element i.e. self adhesive band, is activated by heat such that the connection element moves in contact with the profile parts to connect the profile parts during activation.

Description

Die vorliegende Erfindung bezieht sich auf ein Verbundprofil für Fenster-, Türen-, oder Fassadenelemente mit vorbestimmten Brandschutzeigenschaften und auf einen Isoliersteg für ein solches Verbundprofil.The present invention relates to a composite profile for window, door or facade elements with predetermined fire protection properties and on an insulating web for such a composite profile.

Industriegebäude und öffentliche Gebäude werden häufig in so genannte Brandabschnitte unterteilt. Dazu müssen die eingesetzten Türen und Fenster Brandschutzeigcnsehaften aufweisen. Dies wird mit einer Brandschutzprüfung sichergestellt. Je nach Ergebnis der Brandschutzprüfung wird eine Einteilung in eine Brandschutzklasse vorgenommen, z. B. T30, T60, T90. Dabei gibt der Buchstabe die Anwendung an (z. B. T = Tür) und die Zahl die Zeitdauer in Minuten, die das Bauelement bei der Brandschutzprüfung der Hitzeeinwirkung standgehalten hat.Industrial buildings and public buildings are often divided into so-called fire zones. For this purpose, the doors and windows used must have fire protection properties. This is ensured with a fire protection test. Depending on the result of the fire test, a classification into a fire protection class is made, eg. T30, T60, T90. The letter indicates the application (eg T = door) and the number of minutes in which the component withstood the heat impact during the fire protection test.

Die Brandschutzprüfung schreibt vor, dass das Bauelement nicht versagt, damit die Brandschutzabschnitte sicher getrennt werden, und gasdicht bleibt, damit die bei einem Brand entstehenden Gase von der brandabgewandten Seite abgehalten werden. Wichtig ist auch, dass die Temperaturen auf der brandabgewandten Seite nicht dazu führen dürfen, dass leichtentzündliche Materialien, die sich dort befinden, entzündet werden.The fire test requires that the component does not fail so that the fire protection sections are safely separated, and remains gas-tight, so that the gases produced during a fire are kept away from the side away from the fire. It is also important that the temperatures on the side away from the fire should not cause inflammable materials, which are located there, to be ignited.

In den relevanten Gebäuden werden überwiegend Aluminiumverbundprofile für die Fenster-, Türen-, und Fassadenelemente eingesetzt. Da das Aluminium bei den Brandtemperaturen selbst anfängt zu schmelzen, wird häufig ein Kühlmedium eingesetzt (intumezierende Materialien, z.B. Gips-Alaun, siehe u. a. auch die DE 44 43 762 A1 ). Die Aluminiumverbundprofile bestehen in der Regel aus wenigstens zwei Aluminiumprofilteilen, der Aluminiuminnenschale und der Aluminiumaußenschale, und einem oder mehreren Isolietstegen zur thermischen Trennung der Aluminiuminnenschale von der Aluminiumaußenschale. Die die Aluminiuminnenschale und die Aluminiumaußentschale verbindenden Isolierstege werden bei Anwendungen mit Brandschutzeigenschaften in der Regel nicht ausschließlich aus einem thermoplastischen Kunststoff hergestellt. Entweder wird der thermoplastische Kunststoff durch einen nichtschmelzenden duroplastischen Kunststoff ersetzt, oder es werden wenigstens abschnittsweise Metallbrücken eingesetzt, z. B. Stahlklammern.In the relevant buildings, predominantly aluminum composite profiles are used for the window, door and façade elements. Since the aluminum itself begins to melt at the firing temperatures, a cooling medium is often used (intumescent materials, eg gypsum alum, see, inter alia, the DE 44 43 762 A1 ). The aluminum composite profiles usually consist of at least two aluminum profile parts, the aluminum inner shell and the aluminum outer shell, and one or more Isolietstegen for thermal separation of the aluminum inner shell of the aluminum outer shell. The insulating webs connecting the aluminum inner shell and the aluminum outer shell are generally not exclusively made of a thermoplastic in applications with fire protection properties. Either the thermoplastic material is replaced by a non-melting thermosetting plastic, or at least partially metal bridges are used, for. B. steel brackets.

Duroplastische Kunststoffe haben den Nachteil der schlechten Verarbeitbarkeit. Duroplastische Kunststoffe können insbesondere sehr schlecht gesägt werden, wenn das Verbundprofil beim Konfektionieren in Abschnitte bestimmter Länge zersägt werden muss. Das Verwenden von Stahlklammern oder anderen Metallbrücken hat den Nachteil eines hohen manuellen Arbeitsaufwandes.Thermosetting plastics have the disadvantage of poor processability. In particular, thermosetting plastics can be sawn very poorly if the composite profile has to be sawed into sections of a certain length during assembly. The use of steel clips or other metal bridges has the disadvantage of high manual labor.

Ein weiterer bekannter Ansatz sieht das abschnittsweise Verwenden von Aluminiumbrücken vor, die eine definierte Wärmemenge von der Brandseite zu der brandabgewandten Seite leiten. Ein Nachteil dieses Ansatzes besteht in der permanenten Wärmeableitung im Normalbetrieb, also der verschlechterten thermischen Trennung der Aluminiuminnenschale von der Aluminiumaußenschale.Another well-known approach is the partial use of aluminum bridges that direct a defined amount of heat from the fire side to the side facing away from the fire. A disadvantage of this approach is the permanent heat dissipation in normal operation, so the deterioration of thermal insulation of the aluminum inner shell of the aluminum outer shell.

Die EP 1 024 243 A2 beschreibt ein Verbundprofil mit einem hitzebeständigen Zusatzelement in Form einer Metallklammer, die auf einen Isoliersteg aufgeklebt ist und sich im Normalzustand in Aufnahmeräume der Außenprofilteile erstreckt.The EP 1 024 243 A2 describes a composite profile with a heat-resistant additional element in the form of a metal clip which is glued to an insulating web and extending in the normal state in receiving spaces of the outer profile parts.

Die EP 1 182 317 A2 beschreibt ein Verbundprofil mit Brandschutzeigenschaften, bei dem der Isoliersteg abschnittsweise aus Metall anstelle eines thermoplastischen Kunststoffs besteht.The EP 1 182 317 A2 describes a composite profile with fire protection properties, in which the insulating web sections of metal instead of a thermoplastic material.

Die EP 0 782 334 A2 beschreibt ein Verbundprofil, bei dem die Außenprofilteile durch nicht hitzebeständige Isolierstege verbunden sind. Ein hitzebeständiges Formmaterial ist formschlüssig mit den Außenprofilteilen verbunden.The EP 0 782 334 A2 describes a composite profile in which the outer profile parts are connected by non-heat-resistant insulating bars. A heat-resistant molding material is positively connected to the outer profile parts.

Aus der DE 44 43 762 A1 ist ein Verbundprofil mit Brandschutzeigenschaften bekannt, bei dem die Isolierstege entweder gelochte Metallleisten oder Kunststoffleisten, in denen der Kunststoff abschnittsweise durch Brückensteg aus Metall ersetzt ist, sind. Ein Brandschutzstreifen kann auf einem Isoliersteg vorgesehen sein.From the DE 44 43 762 A1 is a composite profile with fire protection properties known in which the insulating bars either perforated metal strips or plastic strips, in which the plastic is partially replaced by bridge bridge made of metal, are. A fire protection strip may be provided on an insulating web.

Aus der EP 1 327 741 A2 und DE 44 04 565 C1 sind weitere Verbundprofil mit Brandschutzeigenschaften bekannt.From the EP 1 327 741 A2 and DE 44 04 565 C1 are further composite profile with fire protection properties known.

Aufgabe der Erfindung ist es, ein Verbundprofil für Fenster-, Türen-, oder Fassadenelemente mit vorbestimmten Brandschutzeigenschaften und einem Isoliersteg für ein solches Verbundprofil anzugeben, die eine sichere Verbindung der Außenprofilteile im Brandfall und eine gute thermische Trennung im Normalzustand erlauben.The object of the invention is to provide a composite profile for window, door or facade elements with predetermined fire protection properties and an insulating web for such a composite profile specify that allow a secure connection of the outer profile parts in case of fire and good thermal separation in the normal state.

Diese Aufgabe wird gelöst durch ein Verbundprofil nach Anspruch 1 beziehungsweise einen Isoliersteg nach Anspruch 8.This object is achieved by a composite profile according to claim 1 or an insulating web according to claim 8.

Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Further developments of the invention are specified in the dependent claims.

Durch das Vorsehen des durch die im Brandfall auftretende Hitzeentwicklung aktivierten Stellglieds und das aktive Bewegen des Außenprofilteilverbindungselementes in Eingriff mit den Außenprofilteilen wird sowohl eine sichere Verbindung der Außenprofilteile im Brandschutzfall also auch eine definierte Wärmeableitung von der Brandseite zu der brandabgewandten Seite sichergestellt. Darüber hinaus ermöglicht das aktive Bewegen des Außenprofilteilverbindungselementes in die Eingriffsposition, dass das Außenprofilteilverbindungselement im Normalzustand deutlich von den Außenprofilteilen beabstandet ist und somit die thermische Trennung sichergestellt wird.By providing the actuator activated by the heat development occurring in the event of fire and actively moving the outer profile part connecting element into engagement with the outer profile parts, both a secure connection of the outer profile parts in the event of fire, ie a defined heat dissipation from the fire side to the side away from the fire, is ensured. In addition, actively moving the outer profile member connector into the engaged position allows the outer profile member connector to be significantly spaced from the outer profile members in the normal state, thus ensuring thermal separation.

Vorzugsweise wird das Stellglied durch ein im Brandfall durch die Hitzeentwicklung aufschäumendes und z.B. durch Phasenübergang Wasser abspaltendes Brandschutzelement gebildet, so dass das Brandschutzelement einerseits das Außenprofilteilverbindungselement in den Eingriff bewegt und gleichzeitig das Verbundprofil kühlt.Preferably, the actuator is provided by a frothy fire in the event of fire and e.g. formed by phase transition water splitting fire protection element, so that the fire protection element on the one hand, the outer profile part connecting element moves into engagement and at the same time cools the composite profile.

Fig. 1 shows in a cross-sectional view perpendicular to a longitudinal direction z a cross section through a door leaf frame 100 and a Türzargenrahmen 200, which are designed according to an embodiment of the invention. Since the essential elements of the invention of the Door leaf frame 100 and the Türzargenrahmens 200 match, only the door leaf frame 100 is described for simplicity.

Der Türblattrahmen 100 ist ein Beispiel eines Verbundprofils nach einer Ausführungsform der Erfindung und weist ein erstes Außenprofilteil 1 und ein zweites Außenprofilteil 2 auf Die Außenprofilteile 1 und 2 sind Aluminiumprofile. Außenprofilteil bezeichnet hier ein Profilteil, das an einer Außenseite des Verbundprofils angeordnet ist, wie z. B. eine Innenschale oder eine Außenschale. Auch wenn das Verbundprofil beidseitig in einem Raum verbaut wird, wie bei Türen zwischen Innenräume eines Gebäudes, dann sind die Außenprofilteile trotzdem an einer Außenseite des Verbundprofils angeordnet. Die beiden Aluminiumprofile 1,2 sind durch Isolierstege 3, 30 unter Bildung eines Zwischenraums 4 zwischen den Außenprofilteilen 1, 2 verbunden.The door leaf frame 100 is an example of a composite profile according to an embodiment of the invention and has a first outer profile part 1 and a second outer profile part 2. The outer profile parts 1 and 2 are aluminum profiles. External profile part here refers to a profile part which is arranged on an outer side of the composite profile, such as. B. an inner shell or an outer shell. Even if the composite profile is installed on both sides in a room, as in doors between interiors of a building, then the outer profile parts are still arranged on an outer side of the composite profile. The two aluminum profiles 1, 2 are connected by insulating webs 3, 30 to form a gap 4 between the outer profile parts 1, 2.

Die Außenprofilteile können auch aus einem anderen Metall wie Stahl oder einem hitzebeständigen Kunststoff wie einem entsprechenden Duroplast ausgebildet sein. Die Isolierstegteile 3, 30 sind aus einem thermoplastischen Material mit geringer Wärmeleitfähigkeit wie z. B. PA6 ausgebildet. Andere Materialien, die zur Ausbildung von Isolierstegen zur thermischen Trennung von Außenprofilteilen von Fenster-, Türen-, oder Fassadenelementen wie beispielsweise PA66 oder PA66 mit Glasfaserverstärkung oder ähnliches können auch verwendet werden. PA66 hat eine Schmelztemperatur bei ca. 260° C.The outer profile parts may also be formed of another metal such as steel or a heat-resistant plastic such as a corresponding thermosetting plastic. The Isolierstegteile 3, 30 are made of a thermoplastic material with low thermal conductivity such. B. PA6 formed. Other materials that may be used to form insulating webs for thermal separation of exterior profile parts of window, door, or cladding elements such as PA66 or PA66 with glass fiber reinforcement or the like may also be used. PA66 has a melting temperature of approx. 260 ° C.

Bei der in Fig. 1 gezeigten Ausführungsform des Türblattrahmens 100 ist ein Türblatt 40 entsprechend an den Türblattrahmen 100 befestigt Alternativ kann das Türblatt 40 auch durch eine Verglasung oder ähnliches ersetzt werden.At the in Fig. 1 As shown in the embodiment of the door leaf frame 100, a door leaf 40 is fixed to the door leaf frame 100. Alternatively, the door leaf 40 may be replaced with a glazing or the like.

Damit die Tür im Brandfall nicht dadurch versagt, dass die Außenprofilteile 1, 2 durch Schmelzen der Isolierstege 3, 30 nicht mehr mechanisch zusammengehalten werden, ist ein Außenprofilteilverbindungselement 5 vorgesehen, das im Brandfall durch die Hitzeeinwirkung ausgelöst fest und dauerhaft in Eingriff mit den Außenprofilteilen gebracht wird und diese dann fest und dauerhaft verbindet und zusammenhält, selbst falls die Isolierstege 3, 30 schmelzen.Thus, the door does not fail in case of fire, that the outer profile parts 1, 2 are no longer mechanically held together by melting the insulating bars 3, 30, an outer profile part connecting element 5 is provided, which triggered in the event of fire by the action of heat and permanently brought into engagement with the outer profile parts and then firmly and permanently connects and holds them together, even if the insulating bars 3, 30 melt.

Dieses wird nachfolgend unter Bezugnahme auf Fig. 2 genauer beschrieben.This will be described below with reference to Fig. 2 described in more detail.

Der Isoliersteg 3 weist einen Isolierstegkörper 3k auf, der sich in der Längsrichtung z erstreckt und eine Breite b in einer Querrichtung x senkrecht zu der Längsrichtung z und eine Mindeststärke in einer Höhenrichtung y senkrecht zu der Längsrichtung z und der Querrichtung x aufweist. An den in der Querrichtung x voneinander beabstandeten Längsrändern 3r des Isolierstegs sind Verbindungselemente 3v zur Verbindung des Isolierstegs mit dem ersten und zweiten Außenprofilteil 1, 2 vorgesehen. Die Verbindung erfolgt z.B. durch Einrollen in die Ausnehmung 2c. Dabei wird der Einrollhammer 2e in Richtung des Widerlagers 2f gedrückt und das Verbindungselement in bekannter Weise eingerollt. Wenigstens in Teilabschnitten in der Längsrichtung z des Isolierstegs 3 sind Führungswände 3a, 3b parallel zueinander und mit einem vorbestimmten Abstand c der einander zugewandten Innenseiten der Führungswände 3a; 3b voneinander vorgesehen, die in der Höhenrichtung x von dem Isolierstegkörper 3k vorstehen. Die Führungswände 3a, 3b, können auch kontinuierlich entlang der Längsrichtung z ausgebildet sein.The insulating bar 3 has an insulating bar body 3k extending in the longitudinal direction z and a width b in a transverse direction x perpendicular to the longitudinal direction z and a minimum thickness in a height direction y perpendicular to the longitudinal direction z and the transverse direction x. At the longitudinal edges 3r of the insulating web spaced apart in the transverse direction x, connecting elements 3v are provided for connecting the insulating web to the first and second outer profile parts 1, 2. The connection is made, for example, by rolling into the recess 2c. In this case, the roll-in hammer 2e is pressed in the direction of the abutment 2f and the connecting element is rolled in a known manner. At least in partial sections in the longitudinal direction z of the insulating web 3 are guide walls 3a, 3b parallel to each other and with a predetermined distance c of the mutually facing inner sides of the guide walls 3a; 3b provided from each other, which protrude in the height direction x of the Isolierstegkörper 3k. The guide walls 3a, 3b can also be formed continuously along the longitudinal direction z.

Bei der in den Fig. 1 bis 3 gezeigten Ausführangsform des Außenprofilteilverbindungselement 5 ist dieses als eine Metallklammer, vorzugsweise aus Aluminium oder alternativ aus Stahl oder einem anderen Metall, ausgebildet. Die Metallklammer weist im Querschnitt senkrecht zur Längsrichtung z eine U-Form auf, wobei die Schenkel 5s, 5s der U-Form sich parallel und längs der Längsrichtung z erstrecken. An dem freien Ende des einen Schenkels 5s ist ein erster Eingriffsabschnitt 5a ausgebildet. Der Eingriffsabschnitt 5a weist einen abgerundeten Kopf und zur Seite vorstehende Vorsprünge, die als Widerhaken und/oder Einrastelemente dienen, auf. An dem anderen Schenkel 5s ist ein entsprechend geformter zweiter Eingriffsabschnitt 5b ausgebildet. Der erste Eingriffsabschnitt 5 a und der zweite Eingriffsabschnitt 5b sind in der Querrichtung x voneinander getrennt.In the in the Fig. 1 to 3 shown Ausführangsform the outer profile part connecting element 5, this is designed as a metal clip, preferably made of aluminum or alternatively of steel or other metal. The metal clip has a U-shape in cross-section perpendicular to the longitudinal direction z, the legs 5s, 5s of the U-shape extending parallel and along the longitudinal direction z. At the free end of the one leg 5s, a first engagement portion 5a is formed. The engaging portion 5a has a rounded head and laterally projecting protrusions serving as barbs and / or snap-in members. On the other leg 5s a correspondingly shaped second engagement portion 5b is formed. The first engagement portion 5 a and the second engagement portion 5 b are separated from each other in the transverse direction x.

Das Außenprofilteil 1 weist einen Vorsprung auf, an dem ein zu dem ersten Eingriffsabschnitt 5a komplementärer dritter Eingriffsabschnitt 1a vorgesehen ist. Komplementär in diesem Sinne bedeutet, dass der erste Eingriffsabschnitt 5a in den dritten Eingriffsabschnitt 1a zur festen und dauerhaften Verbindung der beiden eingreifen kann, z. B. durch Einschieben des ersten Eingriffsabschnittes in den dritten Eingriffsabschnitt und Verrasten oder Verhaken derselben.The outer profile part 1 has a projection on which a complementary to the first engagement portion 5a third engagement portion 1a is provided. Complementary in this sense means that the first engagement portion 5a can engage in the third engagement portion 1a for firm and permanent connection of the two, z. B. by inserting the first engagement portion in the third engagement portion and latching or hooking the same.

In analoger Weise ist an dem zweiten Außenprofilteil 2 ein Vorsprung mit einem vierten Eingriffsabscbnitt 2b, der komplementär zum zweiten Eingriffsabschnitt 5b ist, ausgebildet.In an analogous manner, a projection with a fourth Eingriffsabscbnitt 2b, which is complementary to the second engagement portion 5b formed on the second outer profile part 2, respectively.

Die Außenseiten der Schenkel 5s weisen einen Abstand voneinander auf, der bis auf eine gleitenden Bewegbarkeit des Außenprofilteils 5 zwischen den Wänden 3a und 3b notwendige Toleranz dem Abstand c der Innenseiten der Wände 3a und 3b des Isoliersteges 3 entspricht. Die Wände 3a und 3b, die sich längs der Längsrichtung z und parallel zueinander erstrecken, stehen senkrecht zu der Querrichtung x in einer Höhenrichtung y vor. Dadurch können sie das Außenprofilteilverbindungselement 5 mit der für eine gleitende Bewegung notwendigen Toleranz während einer Bewegung in der Höhenrichtung y führen.The outer sides of the legs 5s have a distance from each other, which corresponds to a sliding mobility of the outer profile part 5 between the walls 3a and 3b necessary tolerance the distance c of the inner sides of the walls 3a and 3b of the insulating web 3. The Walls 3a and 3b extending along the longitudinal direction z and parallel to each other project perpendicular to the transverse direction x in a height direction y. Thus, they can guide the outer profile member connector 5 with the necessary for a sliding movement tolerance during movement in the vertical direction y.

Die Führungswände 3a und 3b bilden mit dem Isolierstegkörper 3k eine Art Längswanne. Am Boden dieser Längswanne ist zwischen den Führungswänden 3a und 3b ein Stellglied 6 angeordnet. Das Stellglied ist bei dieser Ausführungsform durch ein selbstklebendes Band mit einer epoxidharzgebundenen Intumeszenzschicht 6a und einer Selbstklebeschicht 6b ausgebildet. Das Stellglied 6 hat die Form eines selbstklebenden Brandschutzstreifen. Das epoxidharzgebundene Intumeszenzprodukt enthält thermisch expandierende Komponenten, Flammschutzmittel und Additive. Bei einer Temperatur von ca, 200° C beginnt das epoxidharzgebundene Intumes-zenzprodukt zu expandieren (aufzuschäumen) und erzielt bei entsprechender Hitzeeinwirkung im Brandfall eine bis zu 20-fache Volumenvergrößerung. Bevorzugt enthält der Brandschutzstreifen ein z.B. durch Phasenübergang Wasser abgebendes Material, so dass zusätzlich eine Kühlung erzielt wird. Eine typische Dicke ist z. B. 5mm, so dass abhängig von der Gegenkraft theoretisch bis zu 100mm Stellweg mit dieser Ausführungsform des Stellgliedes 6 erzielt werden könnenThe guide walls 3a and 3b form with the Isolierstegkörper 3k a kind of longitudinal tub. At the bottom of this longitudinal trough an actuator 6 is disposed between the guide walls 3a and 3b. The actuator is formed in this embodiment by a self-adhesive tape with an epoxy-bonded intumescent layer 6a and a self-adhesive layer 6b. The actuator 6 has the form of a self-adhesive fire protection strip. The epoxy resin-bonded intumescent product contains thermally expanding components, flame retardants and additives. At a temperature of approx. 200 ° C, the epoxy-bound intumescenz product begins to expand (foam) and, with the appropriate heat, achieves an increase in volume of up to 20 times in the event of fire. Preferably the fire protection strip contains e.g. Water-releasing material through phase transition, so that additional cooling is achieved. A typical thickness is z. B. 5mm, so that depending on the counterforce theoretically up to 100mm travel can be achieved with this embodiment of the actuator 6

Wie sich in Fig. 2 und 3 leicht erkennen lässt, führt eine entsprechende Volumenvergrößerung der Schicht 6a dazu, dass das Außenprofilteilverbindungselement 5 in der Höhenrichtung y aktiv in Richtung auf den dritten Eingriffsabschnitt la und den vierten Eingriffsabschnitt 2b zu bewegt wird. Wie sich ebenfalls leicht vorstellen lässt, führt das zu einer Bewegung des ersten Eingriffsabschnittes 5a zum Eingriff mit den dritten Eingriffsabschnitt 1a und zu einer aktiven Bewegung des zweiten Eingriffsabschnittes 5b zum Eingriff mit den vierten Eingriffsabschnitt 2b.As is in FIGS. 2 and 3 can be easily seen, a corresponding increase in the volume of the layer 6a causes the outer profile part connecting element 5 in the height direction y is actively moved towards the third engagement portion la and the fourth engagement portion 2b. As also easily imagined, this results in a movement of the first engagement portion 5a for engagement with the third engagement portion 1a and an active movement of the second engagement portion 5b for engagement with the fourth engagement portion 2b.

Alternativ zu dem Klebeband mit dem unter Hitzeeinwirkung aufschäumendem Intumeszenzprodukt sind andere Stellglieder wie Bimetallstreifen oder andere Bimetallelemente, die unter Hitzeeinwirkung verbiegen und so die Stellkraft aufbringen, denkbar. Auch unter Hitze-einwirkung ausgasende Materialien, die in einem Stellglied eingeschlossen sind und dann durch die pneumatische Wirkung des austretenden Gases die Stellbewegung erzeugen, sind denkbar, ebenso wie andere durch Hitzeeinwirkung ausgelöste Stellglieder.As an alternative to the adhesive tape with the Intumeszenzprodukt intumescent under heat other actuators such as bimetallic strips or other bimetallic elements, which bend under the action of heat and thus apply the force, conceivable. Even under heat-ausgasende materials that are included in an actuator and then generate the actuating movement by the pneumatic effect of the exiting gas, are conceivable, as well as other triggered by the heat actuators.

Alternativ zu einem zwischen den Führungswänden 3a, 3b bewegten U-förmigen Außenprofilteilverbindungselement sind auch andere Gestaltungen denkbar. Z. B, kann von dem Isolierstegkörper 3a ein Arm in der Höhenrichtung Y vorstehen, an dem über eine Schwenkachse Kragarme befestigt sind. Diese können dann durch das Stellglied um die Schwenkachse gedreht werden, so dass entsprechende Fingriffsabschnitte an den Kragarmen und an den Außenprofilteilen in Eingriff gebracht werden. Das oder die Außenprofilteilverbindungselemente weisen bevorzugt eine im Vergleich zu den Isolierstegen hohe Wärmeleitfähigkeit auf. Die Länge der Außenprofilteilverbindungselemente 5 in der Längsrichtung z ist dabei so gewählt, dass definierte Wärmeenergiebeträge von der Brandseite auf die brandabgewandte Seite des Verbundprofils geleitet werden können.As an alternative to a U-shaped outer profile part connecting element which is moved between the guide walls 3a, 3b, other configurations are also conceivable. Z. B, can from the Isolierstegkörper 3a projecting an arm in the vertical direction Y, are attached to the above a pivot axis cantilevers. These can then be rotated by the actuator about the pivot axis, so that corresponding Fingriffsabschnitte be brought to the cantilevers and the outer profile parts in engagement. The one or more outer profile part connecting elements preferably have a high thermal conductivity compared to the insulating bars. The length of the outer profile part connecting elements 5 in the longitudinal direction z is chosen so that defined amounts of heat energy can be conducted from the fire side to the brand-facing side of the composite profile.

Selbstverständlich können bei dem Verbundprofil auch andere Maßnahme zur Verbesserung der Brandschutzeigenschaften wie kühlende Brandschutzelemente etc. vorgesehen werden.Of course, other measures for improving the fire protection properties such as cooling fire protection elements etc. may be provided in the composite profile.

Besonders vorteilhaft ist dabei die Verwendung eines kühlenden intumezierenden Produktes, das durch eine Volumenvergrößerung gleichzeitig als Stellglied verwendet werden kann.Particularly advantageous is the use of a cooling intumescent product that can be used by an increase in volume at the same time as an actuator.

Die Verwendung eines Außenprofilteilverbindungselement 5 aus Aluminium zusammen mit einem Isoliersteg aus einem thermoplastischen Material in einem Aluminiumverbundprofil ermöglicht es, das Verbundprofil in bekannter Weise trotz der Brandschutzeigenschaften bei der Konfektionierung zu sägen.The use of an outer profile part connecting element 5 made of aluminum together with an insulating web made of a thermoplastic material in an aluminum composite profile makes it possible to saw the composite profile in a known manner despite the fire protection properties during assembly.

Der Normalzustand des Verbundprofils im obigen Sinne ist ein Zustand, in dem das Verbund-profil fertig hergestellt und gegebenenfalls auch in einem Gebäude eingebaut ist. Vorteilhafterweise ist das Stellglied im Normalzustand noch nicht durch Hitze aktiviert worden, sondern wird erst durch die Hitzeentwicklung im Falle eines Brandes aktiviert. Falls das Verbundprofil bei der Herstellung relativ stark erhitzt wird, also z.B. pulverbeschichtet wird, was bei einer Temperatur von bis zu 200° C geschieht, dann ist die Aktivierungstemperatur des Stellglieds so gewählt, dass sie bevorzugt ein wenig (5 bis 30 ° C, bevorzugt ca. 15° C) über der höchsten Temperatur des Herstellungsvorgangs, also in der Regel über der Pulverbeschichtungstemperatur, liegt. Dann ist das das Außenprofilteilverbindungselement 5 in dem Normalzustand in dem Zwischenraum 4 außer Eingriff mit den Außenprofilteilen 1, 2 und thermisch getrennt von diesen angeordnet.The normal state of the composite profile in the above sense is a state in which the composite profile is finished and optionally installed in a building. Advantageously, the actuator has not yet been activated by heat in the normal state, but is activated only by the heat in the event of a fire. If the composite profile is heated relatively strongly during manufacture, e.g. powder coating, which occurs at a temperature of up to 200 ° C, then the activation temperature of the actuator is selected to preferably a little (5 to 30 ° C, preferably about 15 ° C) above the highest temperature of the manufacturing process, So usually above the powder coating temperature, is. Then, the outer profile member connector 5 is in the normal state in the gap 4 out of engagement with the outer profile parts 1, 2 and thermally separated therefrom.

Alternativ kann die Aktivierungstemperatur des Stellglieds so gewählt werden, dass das Stell-glied in einem bestimmten Herstellungsschritt, also z.B. bei der Pulverbeschichtungstemperatur, voll aktiviert ist. Dann ist das das Außenprofiltellverbindungselement 5 in einem Zustand des Verbundprofils, in dem dieses ein Zwischenprodukt ist, in dem Zwischenraum 4 außer Eingriff mit den Außenprofilteilen 1, 2 und thermisch getrennt von diesen angeordnet. Aber z.B. bei der Pulverbeschichtung, die bei dem Fenster- oder Türhersteller erfolgt, der das Verbundprofil als Zulieferprodukt erworben hat, wird das Stellglied bei der Pulverbeschichtung aktiviert und die feste und dauerhafte Verbindung des Außenprofilteilverbindungselement mit den Außenprofilteilen 1,2 hergestellt. Das bringt zwar einen Nachteil bei der thermischen Trennung, aber einen Vorteil in der Herstellung gegenüber herkömmlichen Lösungen. Das Außenprofilteilverbindungselement 5 kann so bereits bei der Herstellung des Verbundprofils in dem aufgrund des Einrollens nicht zugänglichen Zwischenraum 4 fest verbunden werden.Alternatively, the activation temperature of the actuator can be selected so that the actuator is fully activated in a particular manufacturing step, ie, for example, the powder coating temperature. Then, this is the outer profile connection member 5 in a state of Composite profile in which this is an intermediate, in the gap 4 out of engagement with the outer profile parts 1, 2 and thermally separated from these. But, for example, in the powder coating, which takes place at the window or door manufacturer who has acquired the composite profile as a supplier product, the actuator is activated in the powder coating and made the solid and permanent connection of the outer profile part connector with the outer profile parts 1,2. Although this brings a disadvantage in the thermal separation, but an advantage in the production over conventional solutions. The outer profile part connecting element 5 can thus be firmly connected even in the production of the composite profile in the inaccessible due to the curling gap 4.
