The letter indicates the application (e.g., T = door) and the number of minutes in which the device has withstood the heat exposure fire test.

Die Brandschutzprüfung schreibt vor, dass das Bauelement nicht versagt, so dass die Brandschutzabschnitte sicher getrennt sind, und dass es gasdicht bleibt, damit die bei einem Brand entstehenden Gase von der brandabgewandten Seite abgehalten werden. Zudem dürfen die Temperaturen auf der brandabgewandten Seite nicht dazu führen, dass leicht entzündliche Materialien, die sich dort befinden, entzündet werden.The fire test stipulates that the component does not fail, so that the fire protection sections are safely separated, and that it remains gas-tight, so that the gases produced in the event of a fire are kept away from the side away from the fire. In addition, the temperatures on the side away from the fire must not cause inflammable materials, which are located there, to be ignited.

Für die Fenster-, Türen- und Fassadenelemente werden überwiegend Aluminiumverbundprofile eingesetzt. Da das Aluminium bei den Brandtemperaturen zu schmelzen beginnt, wird häufig ein Kühlmedium (intumeszierende Materialien, z.B. Gips-Alaun, siehe auch die DE 44 43 762 A1 ) eingesetzt. Die Aluminiumverbundprofile bestehen in der Regel aus wenigstens zwei Aluminiumprofilteilen, der Aluminiuminnenschale und der Aluminiumaußenschale, und einem oder mehreren Isolierstegen zur thermischen Isolierung der Aluminiuminnenschale von der Aluminiumaußenschale. Die 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, z.B. Stahlklammern, eingesetzt.Aluminum, composite profiles are predominantly used for the window, door and façade elements. Since the aluminum begins to melt at the fire temperatures, often a cooling medium (intumescent materials, such as gypsum alum, see also the DE 44 43 762 A1 ) used. 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 insulating bars for thermal insulation of the aluminum inner shell of the aluminum outer shell. The connecting insulating bars are usually 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 metal bridges, for example steel clips, are used at least in sections.

Duroplastische Kunststoffe haben den Nachteil der schlechten Verarbeitbarkeit. Insbesondere können sie sehr schlecht gesägt werden, wenn das Verbundprofil beim Konfektionieren in Abschnitte bestimmter Länge zersägt werden muss. Das Verwenden von Stahlklammem oder anderen Metallbrücken hat den Nachteil eines hohen manuellen Arbeitsaufwandes.Thermosetting plastics have the disadvantage of poor processability. In particular, they can be sawed very badly when the composite profile must be sawed into sections of a certain length during assembly. The use of Stahlklammem or other metal bridges has the disadvantage of a 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 darin, dass an den Aluminiumprofilteilen zusätzliche Befestigungsabschnitte zum Verbinden der Aluminiumbrücken vorgesehen sein müssen, weshalb geänderte Aluminiumsysteme gefertigt werden müssen, was mit einem erhöhten Aufwand verbunden ist. Ferner müssen Zusammenbauverfahren modifiziert werden, und bei einer Montage sind zusätzliche Arbeitsschritte erforderlich.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 that additional fastening sections for connecting the aluminum bridges must be provided on the aluminum profile parts, which is why modified aluminum systems must be manufactured, which is associated with increased effort. Furthermore, assembly methods need to be modified, and additional operations are required during assembly.

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 0 785 334 A2 beschreibt ein Verbundprofil, bei dem die Außenprofilteile durch nicht hitzebeständige Isolierstege verbunden sind. Ein hitzebeständiges Formmaterial ist formschlüssig mit den Außenprofilen verbunden.The EP 0 785 334 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 profiles.

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 Brückenstege aus Metall ersetzt ist, sind. Auf einem Isoliersteg kann ein Brandschutzstreifen 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 bridges made of metal, are. On a Isoliersteg a fire protection strip may be provided.

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

Aufgabe der Erfindung ist es, ein Verbundprofil für Fenster-, Türen- oder Fassadenelemente mit vorbestimmten Brandschutzeigenschaften und einen Verbinder und ein Anschlusselement für solch ein Verbundprofil anzugeben, die eine sichere Verbindung der Außenprofilteile im Brandfall ermöglichen, ohne dass eine Anpassung der Außenprofilteile, die mit einem zusätzlichen Aufwand verbunden ist, erforderlich ist.The object of the invention is to provide a composite profile for window, door or facade elements with predetermined fire protection properties and a connector and a connection element for such a composite profile, which allow a secure connection of the outer profile parts in case of fire, without any adaptation of the outer profile parts with An additional expense is required.

Diese Aufgabe wird gelöst durch ein Verbundprofil nach Anspruch 1 bzw. einen Verbinder nach Anspruch 6 und ein Anschlusselement nach Anspruch 10.This object is achieved by a composite profile according to claim 1 or a connector according to claim 6 and a connection element according to claim 10.

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

Das Vorsehen eines Anschlusselements, das Eingriffabschnitte zur Verbindung der Außenprofilteile durch ein brandresistentes Verbindungselement aufweist, zwischen herkömmlichen Außenprofilteilen und herkömmlichen Isolierstegen ermöglicht die brandresistente Verbindung herkömmlicher Aluminiumsysteme, ohne dass diese abgeändert werden müssen. Ferner fallen bei der Montage des Verbundprofils keine zusätzlichen Arbeitsschritte an.The provision of a connection element which has engagement portions for connecting the outer profile parts by a fire-resistant connecting element, between conventional outer profile parts and conventional insulating bars enables the fire-resistant connection of conventional aluminum systems without having to modify them. Furthermore, no additional work steps are required during assembly of the composite profile.

Vorzugsweise sind die Kunststoffisolierstege und die Anschlusselemente Extrusionsteile, wobei die Anschlusselemente vorzugsweise als Aluminiumadapter mit weicherer Legierung als die Aluminiumprofilteile ausgebildet sind. Dies ermöglicht eine einfache Fertigung ohne Nachbearbeitung sowie eine problemlose Konfektionierung der Verbundprofile.Preferably, the Kunststoffisolierstege and the connecting elements are extrusion parts, wherein the connecting elements are preferably designed as aluminum adapter with softer alloy than the aluminum profile parts. This allows a simple production without reworking and a trouble-free assembly of composite profiles.

Fig. 1 zeigt in einer Querschnittsansicht senkrecht zu einer Längsrichtung z ein Verbundprofil gemäß einer Ausführungsform der Erfindung, z.B. für einen Türrahmen. Fig. 1 shows in a cross-sectional view perpendicular to a longitudinal direction z a composite profile according to an embodiment of the invention, for example for a door frame.

Das Verbundprofil weist ein erstes Außenprofilteil 1 und ein zweites Außenprofilteil 2 auf, die sich in Längsrichtung z erstrecken. 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 ist, wie bei Türen zwischen Innenräumen eines Gebäudes, sind die Außenprofilteile trotzdem an einer Außenseite des Verbundprofils angeordnet. Die Außenprofilteile können auch aus einem anderen Metall wie Stahl oder einem hitzebeständigem Kunststoff wie einem entsprechenden Duroplast ausgebildet sein.The composite profile has a first outer profile part 1 and a second outer profile part 2, which extend in the longitudinal direction z. 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. 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, the outer profile parts are still arranged on an outer side of the composite profile. 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.

Die beiden Aluminiumprofilteile 1, 2 sind durch einen Verbinder 10, der sich in der Längsrichtung z erstreckt, unter Bildung eines Zwischenraums 4 zwischen den Außenprofilteilen 1, 2 verbunden. Der Verbinder 10 weist Anschlusselemente 16, 17, 18, 19, die als Adapter dienen und sich in der Längsrichtung z erstrecken, und ein Verbindungselement 15, das sich in der Längsrichtung z erstreckt, auf, die aus denselben Materialien wie die Außenprofilteile ausgebildet sein können. Der Verbinder 10 weist ferner Isolierstege 13a, 13b, die sich in der Längsrichtung z erstrecken, aus einem thermoplastischen Material mit geringer Wärmeleitfähigkeit, z.B. PA6, auf. Die Isolierstege 13a, 13b können auch aus anderen Materialien, die zur Ausbildung von Isolierstegen zur thermischen Trennung von Außenprofilteilen von Fenster-, Türen- oder Fassadenelemente geeignet sind, beispielsweise PA66 oder PA66 mit Glasfaserverstärkung (z.B. PA66GF25) oder Ähnlichem, ausgebildet sein. Die Schmelztemperatur von PA66 liegt bei etwa 260° Celsius.The two aluminum profile parts 1, 2 are connected by a connector 10, which extends in the longitudinal direction z, to form a gap 4 between the outer profile parts 1, 2. The connector 10 has connection members 16, 17, 18, 19 serving as adapters and extending in the longitudinal direction z, and a connection member 15 extending in the longitudinal direction z, which may be formed of the same materials as the outer profile members , The connector 10 further comprises insulating ribs 13a, 13b extending in the longitudinal direction z of a thermoplastic material with low thermal conductivity, e.g. PA6, up. The insulating webs 13a, 13b may also be formed of other materials suitable for forming insulating webs for thermal separation of exterior profile parts of window, door or facade elements, for example PA66 or PA66 with glass fiber reinforcement (e.g., PA66GF25) or the like. The melting temperature of PA66 is around 260 ° Celsius.

Damit die Tür im Brandfall nicht dadurch versagt, dass die Außenprofilteile 1, 2 durch Schmelzen der Isolierstege 13a, 13b nicht mehr mechanisch zusammengehalten werden, ist das Verbindungselement 15 vorgesehen, das über die Anschlusselemente 16, 17 dauerhaft in Eingriff mit den Außenprofilteilen ist und diese fest und dauerhaft verbindet und zusammenhält, selbst wenn die Isolierstege 13a, 13b schmelzen sollten.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 13a, 13b, the connecting element 15 is provided, via the connection elements 16, 17 permanently engaged is with the outer profile parts and this firmly and permanently connects and holds together, even if the insulating bars 13 a, 13 b should melt.

Wie vorher ausgeführt, weist der Verbinder 10 die vier Anschlusselemente 16, 17, 18, 19 auf. Das Anschlusselement 16 weist an einer dem ersten Außenprofilteil 1 zugewandten Seite einen ersten Verbindungsabschnitt 16c zum Verbinden des Anschlusselements 16 mit dem Außenprofilteil 1 durch Einrollen auf. Dabei wird auf bekannte Weise ein Einrollhammer des Außenprofilteils 1 in Richtung eines Widerlagers desselben gedrückt (angerollt) und der Verbindungsabschnitt 16c (hier eine schwalbenschwanzförmige Leiste) eingerollt. Auf der dem Verbindungsabschnitt 16c gegenüberliegenden Seite weist das Anschlusselement 16 einen zweiten Verbindungsabschnitt 16b, 16d zum Verbinden des Anschlusselements 16 mit dem Isoliersteg 13a auf. Die Verbindung des Isolierstegs 13a mit dem Anschlusselement 16 erfolgt auf die gleiche Weise wie die Verbindung des Anschlusselements 16 mit dem Außenprofilteil 1, d.h. durch Einrollen eines Verbindungsabschnitts 13e (hier eine schwalbenschwanzförmige Leiste) des Isolierstegs 13a, wobei ein Einrollhammer 16d des Anschlusselements 16 in Richtung eines Widerlagers 16b des Anschlusselements 16 gedrückt wird.As previously stated, the connector 10 has the four connection elements 16, 17, 18, 19. The connecting element 16 has, on a side facing the first outer profile part 1, a first connecting section 16c for connecting the connecting element 16 to the outer profile part 1 by rolling on. In this case, in a known manner, a roll-in hammer of the outer profile part 1 in the direction of an abutment of the same pressed (rolled) and the connecting portion 16c (here a dovetail bar) rolled up. On the side opposite the connecting section 16c, the connecting element 16 has a second connecting section 16b, 16d for connecting the connecting element 16 to the insulating web 13a. The connection of the insulating web 13a to the connecting element 16 takes place in the same way as the connection of the connecting element 16 to the outer profile part 1, i. by rolling a connecting portion 13e (here, a dovetail-shaped bar) of the insulating strip 13a, wherein a rolling hammer 16d of the connecting element 16 is pressed in the direction of an abutment 16b of the connecting element 16.

Das Ende des Isolierstegs 13a, das nicht mit dem Anschlusselement 16 verbunden ist, ist ebenso durch Einrollen eines Verbindungsabschnitts 13e (hier eine schwalbenschwanzförmige Leiste) mit dem Anschlusselement 18 verbunden, das ebenfalls einen ersten Verbindungsabschnitt 18c zum Verbinden mit dem Außenprofilteil 2 und einen zweiten Verbindungsabschnitt 18b, 18d zum Verbinden mit dem Isoliersteg 13a aufweist. Der erste Verbindungsabschnitt 18c (hier eine schwalbenschwanzförmige Leiste) ist wie vorher beschrieben durch Einrollen mit dem zweiten Außenprofilteil 2 verbunden.The end of the insulating bar 13a which is not connected to the terminal 16 is also connected to the terminal 18 by curling a connecting portion 13e (here a dovetailed bar), which also has a first connecting portion 18c for connecting to the outer profile part 2 and a second connecting portion 18b, 18d for connection to the insulating web 13a. The first connecting portion 18c (here a dovetail-shaped bar) is connected by rolling with the second outer profile part 2 as previously described.

Zusätzlich zu den Verbindungsabschnitten 16b, 16c, 16d weist das Anschlusselement 16 einen Eingriffsabschnitt 16a auf, der in einer Höhenrichtung y senkrecht zu der Längsrichtung z von dem Anschlusselement 16 vorsteht und sich hier parallel zu dem Außenprofilteil 1 erstreckt. Der Eingriffsabschnitt 16a weist im Querschnitt einen abgerundeten Kopf und zur Seite vorstehende Vorsprünge auf, die als Widerhaken und/oder Einrastelemente dienen.In addition to the connecting sections 16b, 16c, 16d, the connecting element 16 has an engagement section 16a which projects in a height direction y perpendicular to the longitudinal direction z from the connecting element 16 and extends parallel to the outer profile section 1 here. The engagement portion 16a has in cross section a rounded head and laterally projecting protrusions serving as barbs and / or snap-in elements.

Das Verbindungselement 15 ist bei der vorliegenden Ausführungsform als eine Metallklammer, vorzugsweise aus Aluminium oder alternativ aus Stahl oder einem anderen Metall, ausgebildet. Alternativ kann das Verbindungselement 15 auch aus Fiberglas oder Ähnlichem bestehen. Das Verbindungselement 15 weist im Querschnitt senkrecht zu der Längsrichtung z eine S-Form auf, wobei zwei sich in der Höhenrichtung y parallel zu den Außenprofilteilen 1, 2 erstreckende Abschnitte durch einen sich in einer Querrichtung x senkrecht zu der Höhenrichtung y und zu der Längsrichtung z erstreckenden Abschnitt verbunden sind. An einem ersten Ende des Verbindungselements 15 ist ein erster Eingriffsabschnitt 15a ausgebildet. Der Eingriffsabschnitt 15a ist komplementär zu dem Eingriffsabschnitt 16a des Anschlusselements 16 ausgebildet, so dass der erste Eingriffsabschnitt 15a zur festen und dauerhaften Verbindung mit dem Eingriffsabschnitt 16a in denselben eingreifen kann, z.B. durch Aufschieben des ersten Eingriffsabschnitts 15a auf den Eingriffsabschnitt 16a und Verrasten oder Verhaken derselben.The connecting element 15 is formed in the present embodiment as a metal clip, preferably made of aluminum or alternatively of steel or another metal. Alternatively, the connecting element 15 may also be made of fiberglass or the like. The connecting element 15 has in cross-section perpendicular to the longitudinal direction z an S-shape, wherein two in the height direction y parallel to the outer profile parts 1, 2 extending portions by a in a transverse direction x perpendicular to the vertical direction y and the longitudinal direction z extending section are connected. At a first end of the connecting element 15, a first engagement portion 15a is formed. The engaging portion 15a is formed to be complementary to the engaging portion 16a of the terminal member 16 so that the first engaging portion 15a can firmly and permanently engage with the engaging portion 16a therein, for example, by sliding the first engaging portion 15a onto the engaging portion 16a and latching or hooking the same ,

An dem zweiten freien Ende weist das Verbindungselement 15 einen zweiten Eingriffsabschnitt 15b auf, der identisch zu dem ersten Eingriffsabschnitt 15a ausgebildet ist. Der zweite Eingriffsabschnitt 15b ist auf die gleiche Weise fest und dauerhaft mit dem Anschlusselement 17 verbindbar bzw. verbunden, das ebenfalls einen ersten Verbindungsabschnitt 17c und einen zweiten Verbindungsabschnitt 17b, 17d aufweist. Das Anschlusselement 17 ist identisch zu dem Anschlusselement 16 ausgebildet. Ferner ist das Anschlusselement 17 auf die gleiche Weise, auf die das Anschlusselement 16 mit dem ersten Außenprofilteil verbindbar bzw. verbunden ist, durch Einrollen mit dem zweiten Außenprofilteil 2 dauerhaft verbindbar bzw. verbunden. Mit dem zweiten Verbindungsabschnitt 17b, 17d des Anschlusselements 17 ist ein Ende des Isolierstegs 13b durch Einrollen verbindbar bzw. verbunden. Das andere Ende des Isolierstegs 13b ist durch Einrollen mit dem Anschlusselement 19 verbindbar bzw. verbunden, das identisch zu dem Anschlusselement 18 ausgebildet ist. Das Anschlusselement 19 ist analog zu dem Anschlusselement 18 dauerhaft mit dem ersten Außenprofilteil 1 verbindbar bzw. verbunden. Auf diese Weise sind das erste und das zweite Außenprofiteil 1, 2 durch den Verbinder 10 mit dem Zwischenraum 4 zwischen denselben fest und dauerhaft verbindbar bzw. verbunden, wobei die Wärmeleitung zwischen denselben aufgrund der geringen Wärmeleitfähigkeit der Isolierstege 13a, 13b relativ gering ist.At the second free end, the connecting element 15 has a second engagement portion 15b, which is identical to the first engagement portion 15a. The second engagement portion 15b is in the same way permanently and permanently connected to the connection element 17, which also has a first connection portion 17c and a second connection portion 17b, 17d. The connection element 17 is identical to the connection element 16. Further, the connecting element 17 in the same manner to which the connecting element 16 is connected or connected to the first outer profile part, connected by rolling with the second outer profile part 2 permanently connected or connected. With the second connecting portion 17b, 17d of the connecting element 17, an end of the insulating web 13b is connected by rolling or connected. The other end of the insulating web 13 b is connected or connected by rolling with the connecting element 19, which is identical to the connecting element 18 is formed. The connecting element 19 is permanently connectable or connected analogously to the connection element 18 with the first outer profile part 1. In this way, the first and second Außenprofiteil 1, 2 by the connector 10 with the gap 4 between the same firmly and permanently connected or connected, wherein the heat conduction between them due to the low thermal conductivity of the insulating bars 13a, 13b is relatively low.

Das Verbindungselement 15 kann sich durchgehend mit einer Länge l0 oder nur abschnittsweise in der Längsrichtung z, d.h. in Form einer Mehrzahl n von Verbindungselementen 15, die jeweils eine Länge l1 in der Längsrichtung z aufweisen, erstrecken. Eine Anpassung der Gesamtlänge, also z.B. l0 bzw. n·11 des Verbindungselements 15 bzw. der Verbindungselemente 15 ermöglicht, einen definierten Wärmeübertrag von der Brandseite zu der brandabgewandten Seite im Brandfall einzustellen. Der Wärmeübertrag bewirkt eine Kühlung des Außenprofilteils auf der Brandseite und somit eine längere Standzeit des Verbundprofils im Brandfall.The connecting element 15 may be continuous with a length l 0 or only partially in the longitudinal direction z, ie in the form of a plurality n of connecting elements 15, each having a length l 1 in the longitudinal direction z extend. An adaptation of the total length, that is, for example, l 0 or n · 1 1 of the connecting element 15 and the connecting elements 15 allows to set a defined heat transfer from the fire side to the side facing away from the fire in case of fire. The heat transfer causes cooling of the outer profile part on the fire side and thus a longer service life of the composite profile in case of fire.

Die Form der Eingriffsabschnitte 15a, 15b des Verbindungselements 15 und der Eingriffsabschnitte 16a, 17a der Anschlusselemente 16, 17 ist vertauschbar. Das heißt, die Eingriffsabschnitte 15a, 15b können in Form der Eingriffsabschnitte 16a, 17a ausgebildet sein, und dementsprechend sind dann die Eingriffsabschnitte 16a, 17a in Form der Eingriffsabschnitte 15a, 15b ausgebildet. Ferner können die Eingriffsabschnitte 15a, 15b, 16a, 17a andere Formen aufweisen, die eine sichere und dauerhafte Verbindung des Verbindungselements 15 mit den Anschlusselementen 16, 17 erlauben.The shape of the engaging portions 15a, 15b of the connecting member 15 and the engaging portions 16a, 17a of the connecting members 16, 17 is interchangeable. That is, the engaging portions 15a, 15b may be formed in the shape of the engaging portions 16a, 17a, and accordingly, the engaging portions 16a, 17a are formed in the form of the engaging portions 15a, 15b. Furthermore, the engagement portions 15a, 15b, 16a, 17a may have other shapes that allow a secure and permanent connection of the connecting element 15 with the connecting elements 16, 17.

Fig. 2 zeigt eine Modifikation des Verbundprofils aus Fig. 1. Gleiche Teile sind mit gleichen Bezugsziffern bezeichnet. Der in Fig. 2 gezeigte Verbundprofilrahmen unterscheidet sich von dem Verbundprofilrahmen von Fig. 1 dadurch, dass die Anschlusselemente 16, 17, 18, 19 unterschiedlich ausgebildet sind. Während in Fig. 1 die Einrollhämmer 16d, 17d, 18d im eingebauten Zustand des Verbinders 10 jeweils in dem Zwischenraum 4 angeordnet sind, sind bei der in Fig. 2 gezeigten Modifikation die Einrollhämmer 16d, 17d, 18d jeweils auf der anderen Seite, d.h. der Außenseite, ausgebildet, und die Widerlager 16b, 17b, 18b sind in dem Zwischenraum 4 angeordnet. Fig. 2 shows a modification of the composite profile Fig. 1 , Identical parts are designated by the same reference numerals. The in Fig. 2 Composite profile frame shown differs from the composite profile frame of Fig. 1 in that the connecting elements 16, 17, 18, 19 are designed differently. While in Fig. 1 the rolling hammers 16d, 17d, 18d are arranged in the installed state of the connector 10 in each case in the intermediate space 4, are in the in Fig. 2 1, the rolling hammers 16d, 17d, 18d are respectively formed on the other side, ie, the outside, and the abutments 16b, 17b, 18b are disposed in the space 4.

Fig. 3 zeigt eine weitere Modifikation des Verbundprofils aus Fig. 1. Bei der in Fig. 3 gezeigten Modifikation weisen die Anschlusselemente 16, 17, 18, 19 anstelle eines Einrollhammers 16d, 17d, 18d und eines Widerlagers 16b, 17b, 18b jeweils zwei Einrollhämmer 16d, 17d, 18d auf. Fig. 3 shows a further modification of the composite profile Fig. 1 , At the in Fig. 3 As shown modification, the connecting elements 16, 17, 18, 19 instead of a roll-in hammer 16d, 17d, 18d and an abutment 16b, 17b, 18b each have two roll hammers 16d, 17d, 18d.

Fig. 4 zeigt eine andere Ausführungsform eines Verbundprofils. Gleiche Teile sind erneut mit den gleichen Bezugsziffern versehen. Fig. 4 shows another embodiment of a composite profile. The same parts are again provided with the same reference numbers.

Bei der in Fig. 4 gezeigten Ausführungsform sind zwei Verbinder 10, die sich in der Längsrichtung z erstrecken, vorgesehen. Der Verbinder 10 unterscheidet sich von den vorher beschriebenen Verbindern dadurch, dass ein Verbindungselement 15 und ein entsprechender Isoliersteg 13c und zwei Anschlusselemente 16, 17 anstelle von einem Verbindungselement 15, 2 Isolierstegen 13a, 13b und 4 Anschlusselementen 16, 17, 18, 19 den Verbinder bilden. Wie aus Fig. 4 ersichtlich ist, erstreckt sich von jedem der Anschlusselemente 16, 17 ein Eingriffsabschnitt 16a, 17a in den Zwischenraum 4, und der erste Verbindungsabschnitt 15a und der zweite Verbindungsabschnitt 15b eines Verbindungselement 15 sind auf die vorher beschriebene Weise mit den Eingriffsabschnitten 16a, 17a in Eingriff. Zwischen dem ersten Eingriffsabschnitt 15a und dem zweiten Eingriffsabschnitt 15b weist das Verbindungselement 15 einen sich in der Querrichtung x erstreckenden Abschnitt auf. Durch die Verbindung der Außenprofilteile 1, 2 durch zwei in der Höhenrichtung y voneinander beabstandete Verbinder 10 wird die sichere und dauerhafte Verbindung der Außenprofilteile 1, 2 verbessert.At the in Fig. 4 In the embodiment shown, two connectors 10 extending in the longitudinal direction z are provided. The connector 10 differs from the previously described connectors in that a connecting element 15 and a corresponding insulating web 13c and two connecting elements 16, 17 instead of a connecting element 15, second Insulating webs 13 a, 13 b and 4 connecting elements 16, 17, 18, 19 form the connector. How out Fig. 4 is visible, extends from each of the connecting members 16, 17, an engaging portion 16 a, 17 a in the gap 4, and the first connecting portion 15 a and the second connecting portion 15 b of a connecting element 15 in the manner previously described with the engaging portions 16 a, 17 a into engagement. Between the first engaging portion 15a and the second engaging portion 15b, the connecting member 15 has a portion extending in the transverse direction x. By connecting the outer profile parts 1, 2 by two in the height direction y spaced connector 10, the secure and permanent connection of the outer profile parts 1, 2 is improved.

In Fig. 6 ist der Abschnitt eines der Verbindungselemente 15, der den ersten Eingriffsabschnitt 15a mit dem zweiten Eingriffsabschnitt 15b verbindet, konvex, d.h. derart ausgebildet, dass er sich in den zwischen den Außenprofilteilen 1, 2 vorgesehen Zwischenraum 4 wölbt, so dass ein durch den Isoliersteg 13c, die Anschlusselemente 16, 17 und das Verbindungselement 15 definierter Hohlraum 10h vergrößert ist. In den so ausgebildeten Hohlraum 10h kann ein Schaum 20 gefüllt sein. Auf diese Weise kann ein Armierungselement zur Verstärkung des Verbundprofilrahmens von Fig. 6 ausgebildet werden. Ferner wird durch den Schaum eine thermische Isolierung zwischen dem ersten und dem zweiten Außenprofilteil verbessert.In Fig. 6 is the portion of one of the connecting elements 15, which connects the first engagement portion 15a with the second engagement portion 15b, convex, that is formed such that it bulges in the provided between the outer profile parts 1, 2 gap 4 so that a through the insulating web 13c, the connecting elements 16, 17 and the connecting element 15 defined cavity 10h is increased.

In Fig. 7 sind die Anschlusselemente 18, 19, die nicht mit dem Verbindungselement 15 in Eingriff sind, weggelassen. Dies verringert die Zahl der verwendeten Bauteile und verbessert die thermische Isolierung zwischen dem ersten Außenprofilteil 1 und dem zweiten Außenprofilteil 2.In Fig. 7 are the connecting elements 18, 19, which are not engaged with the connecting element 15, omitted. This reduces the number of components used and improves the Thermal insulation between the first outer profile part 1 and the second outer profile part. 2

Bei den in Fig. 1 bis 7 gezeigten Ausführungsformen des Verbundprofils befindet sich das Verbindungselement 15 bei einer Verbindung des Außenprofilteils 1 und des Außenprofilteils 2 durch den Verbinder 10 stets in Eingriff mit den Anschlusselementen 16, 17. Die europäische Patentanmeldung EP08011031 desselben Anmelders offenbart ein Verbundprofil, bei dem ein Verbindungselement 15 erst im Brandfall Außenprofilteile 11, 12 des Verbundprofils verbindet. Dies ist im Folgenden unter Bezugnahme auf Fig. 8 beschrieben.At the in Fig. 1 to 7 shown embodiments of the composite profile, the connecting element 15 is at a compound of the outer profile part 1 and the outer profile part 2 through the connector 10 is always in engagement with the connecting elements 16, 17. The European patent application EP08011031 The same applicant discloses a composite profile in which a connecting element 15 connects outer profile parts 11, 12 of the composite profile only in case of fire. This is below with reference to Fig. 8 described.

Ein die Außenprofilteile 11, 12 verbindender Isoliersteg 23 weist einen Isolierstegkörper 23k auf, der sich in einer 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 des Isolierstegs 23 sind Verbindungselemente 23v zur Verbindung des Isolierstegs mit dem ersten und zweiten Außenprofilteil 11, 12 vorgesehen. Die Verbindung erfolgt z.B. durch Einrollen in die Ausnehmung 12c. Dabei wird der Einrollhammer 12e in Richtung des Widerlagers 12f gedrückt (angerollt) und das Verbindungselement in bekannter Weise eingerollt. Wenigstens in Teilabschnitten in der Längsrichtung z des Isolierstegs 23 sind Führungswände 23a, 23b parallel zueinander und mit einem vorbestimmten Abstand c der einander zugewandten Innenseiten der Führungswände 23a, 23b voneinander vorgesehen, die in der Höhenrichtung x von dem Isolierstegkörper 23k vorstehen. Die Führungswände 23a, 23b können auch kontinuierlich entlang der Längsrichtung z ausgebildet sein.An insulating web 23 connecting the outer profile parts 11, 12 has an insulating web body 23k extending in a longitudinal direction z and a width b in a transverse direction x perpendicular to the longitudinal direction z and a minimum thickness in a vertical direction y perpendicular to the longitudinal direction z and the transverse direction x has. At the longitudinal edges of the insulating web 23 spaced apart in the transverse direction x, connecting elements 23v for connecting the insulating web to the first and second outer profile parts 11, 12 are provided. The connection occurs e.g. by rolling into the recess 12c. In this case, the roll-in hammer 12e is pressed (rolled) in the direction of the abutment 12f and the connecting element is rolled in a known manner. At least in partial sections in the longitudinal direction z of the insulating web 23, guide walls 23a, 23b are provided parallel to each other and at a predetermined distance c of the mutually facing inner sides of the guide walls 23a, 23b which project from the insulating web body 23k in the height direction x. The guide walls 23a, 23b can also be formed continuously along the longitudinal direction z.

Das Verbindungselement 15 weist im Querschnitt senkrecht zur Längsrichtung z eine U-Form auf, wobei sich die Schenkel 15s, 15s der U-Form parallel und längs der Längsrichtung z erstrecken. An dem freien Ende des einen Schenkels 15s ist ein erster Eingriffsabschnitt 15a ausgebildet. An dem anderen Schenkel 15s ist ein entsprechend geformter zweiter Eingriffsabschnitt 15b ausgebildet. Der erste Eingriffsabschnitt 15a und der zweite Eingriffsabschnitt 15b sind in der Querrichtung x voneinander getrennt.The connecting element 15 has a U-shape in cross-section perpendicular to the longitudinal direction z, wherein the legs 15 s, 15 s of the U-shape extend parallel and along the longitudinal direction z. At the free end of the one leg 15s, a first engagement portion 15a is formed. On the other leg 15s, a correspondingly shaped second engagement portion 15b is formed. The first engagement portion 15a and the second engagement portion 15b are separated from each other in the transverse direction x.

Das Außenprofilteil 11 weist einen Vorsprung auf, an dem ein zu dem ersten Eingriffsabschnitt 15a komplementärer Eingriffsabschnitt 11a vorgesehen ist. In analoger Weise ist an dem zweiten Außenprofilteil 12 ein Vorsprung mit einem Eingriffsabschnitt 12b, der komplementär zu dem zweiten Eingriffsabschnitt 15b ist, ausgebildet. Das Außenprofilteil 11 ist ferner über einen herkömmlichen Isoliersteg 24 mit dem Außenprofilteil 12 verbunden.The outer profile part 11 has a projection on which a to the first engagement portion 15 a complementary engagement portion 11 a is provided. In an analogous manner is at the second Outer profile part 12, a projection having an engagement portion 12 b, which is complementary to the second engagement portion 15 b is formed. The outer profile part 11 is also connected via a conventional insulating web 24 with the outer profile part 12.

Die Außenseiten der Schenkel 15s des Verbindungselements 15 weisen einen Abstand voneinander auf, der bis auf eine für eine gleitende Bewegbarkeit des Verbindungselements 15 zwischen den Wänden 23a und 23b notwendige Toleranz dem Abstand c der Innenseiten der Wände 23a und 23b des Isoliersteges 23 entspricht. Die Wände 23a und 23b, 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 15 mit der für eine gleitende Bewegung notwendigen Toleranz während einer Bewegung in der Höhenrichtung y führen.The outer sides of the legs 15s of the connecting element 15 have a distance from each other, which corresponds to the distance c of the inner sides of the walls 23a and 23b of the insulating web 23 except for a necessary for a sliding mobility of the connecting element 15 between the walls 23a and 23b tolerance. The walls 23a and 23b, which extend along the longitudinal direction z and parallel to each other, project perpendicular to the transverse direction x in a height direction y. This allows them to guide the outer profile member connector 15 with the necessary for a sliding movement tolerance during movement in the height direction y.

Die Führungswände 23a und 23b bilden mit dem Isolierstegkörper 23k eine Art Längswanne. Am Boden dieser Längswanne ist zwischen den Führungswänden 23a und 23b ein Stellglied 26 angeordnet. Das Stellglied ist bei dieser Ausführungsform durch ein selbstklebendes Band mit einer epoxidharzgebundenen Intumeszenzschicht 26a und einer Selbstklebeschicht 26b ausgebildet. Das Stellglied 26 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 Intumeszenzprodukt 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. 5 mm, so dass abhängig von der Gegenkraft theoretisch bis zu 100 mm Stellweg mit dieser Ausführungsform des Stellgliedes 26 erzielt werden können.The guide walls 23a and 23b form with the Isolierstegkörper 23k a kind of longitudinal tub. At the bottom of this longitudinal trough an actuator 26 is disposed between the guide walls 23a and 23b. The actuator is formed in this embodiment by a self-adhesive tape having an epoxy-bonded intumescent layer 26a and a self-adhesive layer 26b. The actuator 26 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 about 200 ° C, the epoxy-bound Intumeszenzprodukt begins to expand (froth) and achieved with appropriate heat exposure in case of fire up to a 20-fold increase in volume. 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. 5 mm, so that depending on the counterforce theoretically up to 100 mm travel can be achieved with this embodiment of the actuator 26.

Wie sich in Fig. 8 leicht erkennen lässt, führt eine entsprechende Volumenvergrößerung der Schicht 26a dazu, dass das Verbindungselement 15 in der Höhenrichtung y aktiv in Richtung auf den Eingriffsabschnitt 11 a und den Eingriffsabschnitt 12b zu bewegt wird. Wie sich ebenfalls leicht vorstellen lässt, führt das zu einer Bewegung des ersten Eingriffsabschnittes 15a zum Eingriff mit den Eingriffsabschnitt 11 a und zu einer aktiven Bewegung des zweiten Eingriffsabschnittes 15b zum Eingriff mit den Eingriffsabschnitt 12b.As is in Fig. 8 can be easily seen, a corresponding increase in volume of the layer 26a causes the connecting element 15 in the height direction y is actively moved towards the engagement portion 11a and the engagement portion 12b. As is also easy to imagine, this leads to a movement of the first engagement portion 15a for engagement with the engagement portion 11a and to an active movement of the second engagement portion 15b for engagement with the engagement portion 12b.

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 Hitzeeinwirkung 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. Also ausgasende 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.

Nun wird unter Bezugnahme auf Fig. 5 und Fig. 8 eine Modifikation der in Fig. 5 gezeigten Ausführungsform beschreiben. Dabei ist der in Fig. 8 gezeigte Isoliersteg 23 mit dem Verbindungselement 15 und dem Stellglied 26 anstelle des Isolierstegs 13d aus Fig. 5 vorgesehen. Die Eingriffsabschnitte 16a, 17a der Anschlusselemente 16, 17 sind analog zu den in Fig. 8 gezeigten Eingriffsabschnitten 11a und 12b ausgebildet und mit den Eingriffsabschnitten 15a, 15b des Verbindungselements 15 ausgerichtet. Es ist offensichtlich, dass die Formen der jeweiligen Eingriffsabschnitte vertauschbar sind. Auf diese Weise kann auch bei der Modifikation der in Fig. 5 gezeigten Ausführungsform die vorher beschriebene Wirkung erzielt werden.Now, referring to Fig. 5 and Fig. 8 a modification of in Fig. 5 described embodiment. Here is the in Fig. 8 insulating strip 23 shown with the connecting element 15 and the actuator 26 instead of the insulating strip 13d Fig. 5 intended. The engagement portions 16a, 17a of the connection elements 16, 17 are analogous to those in Fig. 8 formed engaging portions 11a and 12b and aligned with the engaging portions 15a, 15b of the connecting element 15. It is obvious that the shapes of the respective engaging portions are interchangeable. In this way, also in the modification of in Fig. 5 shown embodiment, the previously described effect can be achieved.

Alternativ ist bei einer weiteren Modifikation der in Fig. 5 gezeigten Ausführungsform anstelle des Isolierstegs 13c der Isoliersteg 23 aus Fig. 8 vorgesehen. Die Eingriffsabschnitte 17a, 17b sind an einem sich über die Führungswände 23a, 23b hinaus erstreckenden Abschnitt der Anschlusselemente 16, 17 ausgebildet, analog zu den in Fig. 8 an den Außenprofilteilen 11, 12 ausgebildeten Eingriffsabschnitten 11a, 12b.Alternatively, in a further modification of the in Fig. 5 shown embodiment instead of the insulating web 13c of the insulating web 23 Fig. 8 intended. The engagement sections 17a, 17b are formed on a section of the connection elements 16, 17 extending beyond the guide walls 23a, 23b, analogous to those in FIG Fig. 8 formed on the outer profile parts 11, 12 engagement portions 11 a, 12 b.

Alternativ zu den hier gezeigten S-förmigen oder U-förmigen Verbindungselementen 15 sind auch andere Formen für die Verbindungselemente 15 denkbar, beispielsweise eine Mäanderform oder mehrere aufeinanderfolgende S-förmige Abschnitte.As an alternative to the S-shaped or U-shaped connecting elements 15 shown here, other shapes for the connecting elements 15 are also conceivable, for example a meander shape or a plurality of successive S-shaped sections.

Bei dem Verbundprofil können auch andere Maßnahmen zur Verbesserung der Brandschutzeigenschaften wie kühlende Brandschutzelemente etc. vorgesehen sein. Besonders vorteilhaft ist dabei die Verwendung eines kühlenden intumeszierenden Produkts, das durch eine Volumenvergrößerung gleichzeitig als Stellglied verwendet werden kann.In the composite profile, other measures to improve the fire protection properties such as cooling fire protection elements, etc. may be provided. Particularly advantageous is the use of a cooling intumescent product, which can be used by an increase in volume at the same time as an actuator.

Die Verwendung eines Verbindungselements aus Aluminium zusammen mit Anschlusselementen aus Aluminium ermöglicht es, das Verbundprofil auf herkömmliche Weise bei der Konfektionierung zu sägen.The use of an aluminum fastener together with aluminum fasteners makes it possible to cut the composite profile in a conventional manner during assembly.

Durch die Verwendung der als Adapter ausgebildeten Anschlusselemente ist keine Änderung herkömmlicher Aluminiumverbundprofilelemente notwendig. Ferner ist die Bautiefe unter Verwendung unterschiedlicher Isolierstege variierbar, wobei die Anschlusselemente stets gleich ausgebildet sind. Die Verwendung von Extrusionsteilen ermöglicht eine einfache Fertigung ohne Nachbearbeitung. Insbesondere ermöglicht die Verwendung der Anschlusselemente die Vermeidung eines zusätzlichen Fertigungsaufwands bei dem Hersteller der Aluminiumaußenprofilteile.By using the adapter elements designed as an adapter, no change of conventional aluminum composite profile elements is necessary. Furthermore, the depth can be varied using different insulating webs, wherein the connecting elements are always the same design. The use of extrusion parts allows for easy production without reworking. In particular, the use of the connection elements allows the avoidance of an additional manufacturing effort at the manufacturer of the aluminum outer profile parts.

Eine Verwendung eines schubweichen (z.B. aus der DE 20 2007 016 649 U1 bekannten) Isolierstegs sowie eines wenigstens einseitigen schubweichen Eingriffs des Verbindungselements am Adapter ermöglicht einen schubweichen Verbund des Verbundprofils.A use of a push soft (eg from the DE 20 2007 016 649 U1 known) insulating web and at least one side push-soft engagement of the connecting element on the adapter allows a push soft composite of the composite profile.

Zur Verbesserung der Verbindung der Anschlusselemente mit den Außenprofilteilen können die Anschlusselemente gerändelt sein. Ferner können die Anschlusselemente eine weichere Legierung als die Außenprofilteile aufweisen. Zur weiteren Verbesserung der Verbindung zwischen den Anschlusselementen und den Außenprofilteilen können auch Drähte vorgesehen sein.To improve the connection of the connection elements with the outer profile parts, the connection elements can be knurled. Furthermore, the connection elements may have a softer alloy than the outer profile parts. To further improve the connection between the connection elements and the outer profile parts and wires can be provided.

Die Verriegelung durch das Verbindungselement kann auch unter Verwendung von Aluminiumklammern, Blechkammem, Drahtelementen oder Fachwerkbauteilen erfolgen.The locking by the connecting element can also be done using aluminum brackets, Blechkammem, wire elements or truss components.

Die Kunststoffisolierstege können eine andere Form des Verbindungsabschnitts als einen Schwalbenschwanz aufweisen, z.B. Rechtecke, polygonale Formen, etc.The Kunststoffisolierstege may have a different shape of the connecting portion than a dovetail, e.g. Rectangles, polygonal shapes, etc.

Die Verbindung der Isolierstege mit den Anschlusselementen kann variabel gestaltet werden. Auf diese Weise können auch nicht einrollbare Kunststoffisolierstege für das Verbundprofil verwendet werden. Sie können auf andere Weise als durch Einrollen mit den Anschlusselementen verbunden werden, beispielsweise durch Vergießen, Verkleben, Anextrudieren, etc. Ferner kann die Verbindung des Verbindungselements mit den Anschlusselementen variabel gestaltet werden, zum Beispiel durch Verwenden eines Verbindungsverfahrens, das aus Einrasten, Einrollen, Einpressen, Einklemmen, Verkleben, Verschweißen, Verschrauben, Vernieten oder einer Kombination derselben ausgewählt ist.The connection of the insulating webs with the connecting elements can be made variable. In this way, non-rollable Kunststoffisolierstege can be used for the composite profile. They can be connected in other ways than by rolling with the connection elements, for example by casting, gluing, extrusion, etc. Furthermore, the connection of the connecting element with the connection elements can be made variable For example, by using a bonding method selected from snapping, curling, press-fitting, pinching, gluing, welding, bolting, riveting, or a combination thereof.
