Description

Die Erfindung betrifft ein Verbundprofil für Rahmen von Fenstern, Türen, Fassadenelementen und dgl. nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a composite profile for frames Windows, doors, facade elements and the like. According to the generic term of claim 1.

Ein Verbundprofil dieser Art ist aus DE-A-31 02 616 bekannt.A composite profile of this type is known from DE-A-31 02 616.

Einem solchen Verbundprofil liegt folgender technischer Hintergrund zugrunde: Es kann vorkommen, daß der den Isoliersteg bildende Kunststoff z.B. durch Alterung oder punkt- oder linienförmig angepreßte Halteelemente brüchig wird oder reißt und das Verbundprofil mangels Zusammenhalt seiner Metallprofilteile durch den Isoliersteg auseinanderbricht, wodurch es zu beträchtlichen Gefährdungen kommen kann. Auch ist der den Isoliersteg bildende Kunststoff in der Regel nicht feuer- oder hitzebeständig, so daß er beispielsweise im Falle eines Brandes oder beim Schweißen der Metallprofilteile verschmort, wodurch der Zusammenhalt der beiden Metallprofilteile ebenfalls verlorengehen kann. Daher kann z.B. ein äußeres, nicht mehr mit dem inneren verbundenes Metallprofilteil bei Feuer von einer Gebäudewand herabstürzen und am Boden schweren Sach- und Personenschaden anrichten. Auch die Einlagerung von an sich nicht brennbaren, jedoch losen Verstärkungsfasern, beispielsweise Glas- oder Kohlenstoffasern, die vornehmlich nur in einer Richtung verlaufen und nicht miteinander verbunden sind, ändert hieran nichts, weil diese zu einem festen Halt des einen Metallprofilteils am anderen nichts beitragen können, wenn der den Isoliersteg bildende Kunststoff seinen Zusammenhalt verloren hat.Such a composite profile is more technical Background: It can happen that the isolating bridge forming plastic e.g. through aging or Pointed or linearly pressed holding elements brittle is or tears and the composite profile for lack of cohesion its metal profile parts breaks apart through the insulating web, which leads to considerable dangers can. It is also the plastic that forms the insulating bridge usually not fire or heat resistant, so he for example in the event of a fire or welding the metal profile parts scorched, creating cohesion of the two metal profile parts can also be lost. Therefore e.g. an outer, no longer with the inner connected metal profile part in case of fire from a building wall Fall down and cause serious damage to property and personal injury to serve. Even the storage of itself non-flammable, but loose reinforcing fibers, for example Glass or carbon fibers, primarily run only in one direction and not connected are not changing anything because these become a fixed one Nothing holds one metal profile part to the other can contribute if the plastic forming the insulating web has lost its cohesion.

Daher ist in der oben erwähnten Druckschrift DE 31 02 616 Al vorgesehen, daß der den Isoliersteg bildende Kunststoff mit einem Faserverbundskelett aus hitzebeständigen Fasern kombiniert und das Faserverbundskelett derart mit den Metallprofilteilen verbunden ist, daß es auch bei degeneriertem Kunststoff des Isoliersteges, also insbesondere im Brandfall, einen Zusammenhalt der Metallprofilteile sicherstellt.Therefore, in the above-mentioned document DE 31 02 616 Al provided that the plastic forming the insulating web with a fiber composite skeleton made of heat-resistant fibers combined and the fiber composite skeleton in this way with the metal profile parts is connected that it is also with degenerate Plastic of the insulating web, in particular in Fire, a cohesion of the metal profile parts ensures.

Das Faserverbundskelett besteht bei diesem bekannten Verbundprofil aus Glas- oder Kohlefasern, die in einfacher Weise um an beiden Enden des Isoliersteges vorgesehene Verankerungselemente herumgewickelt sind, wobei diese Wicklungen in den Kunststoff des Isoliersteges eingebettet sind oder an dessen Außenseiten liegen können. Die Herstellung solcher Wicklungen ist fertigungstechnisch nicht einfach. Außerdem haben die einzelnen Wicklungen keinen Zusammenhalt untereinander, wodurch die Festigkeit des Isoliersteges und damit des Verbundprofils bei Beschädigung des den Isoliersteg bildenden Kunststoffes beeinträchtigt sein kann.The fiber composite skeleton consists of this known composite profile Made of glass or carbon fibers, which in simpler Way provided at both ends of the insulating web Anchoring elements are wrapped around, these Windings embedded in the plastic of the insulating bridge are or may be on the outside. The production such windings is not manufacturing technology simple. In addition, the individual windings have none Cohesion with each other, increasing the strength of the Isoliersteges and thus the composite profile in the event of damage of the plastic forming the insulating bridge can be.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Verbundprofil so auszubilden, daß es einfacher herzustellen und die Festigkeit des Isoliersteges und damit des Verbundprofils, insbesondere auch im Brandfall, generell verbessert ist. It is an object of the invention to provide a generic composite profile to train so that it is easier to manufacture and the strength of the insulating web and thus the composite profile, especially in the event of fire, generally improved is.

Die Aufgabe wird bei einem gattungsgemäßen Verbundprofil durch die im Kennzeichnungsteil des Patentanspruchs 1 stehenden Merkmale gelöst.The task is with a generic composite profile by standing in the characterizing part of claim 1 Features resolved.

Durch die Ausbildung als Band kann das Faserverbundskelett in einfacher Weise vorgefertigt werden, wobei die Fasern im Band durch Weben, Flechten, Wirken, Stricken oder dergleichen untereinander zusammengehalten sein können. Die verdickten Randabschnitte des Bandes gestatten eine zuverlässige Verankerung an den Metallprofilteilen. Schließlich vermittelt das Band als solches dem Isoliersteg einen besseren inneren Zusammenhalt als lose Faserwicklungen.By training as a band, the fiber composite skeleton are prefabricated in a simple manner, the fibers in the band by weaving, braiding, knitting, knitting or the like can be held together. The thickened edge portions of the tape allow reliable Anchoring to the metal profile parts. Finally the tape as such conveys a better one to the insulating bridge inner cohesion as loose fiber windings.

Die Fig. 1 zeigt ein z.B. für die Herstellung von Fenstern, Türen oder Fassadenelementen geeignetes Verbundprofil 1 mit einem inneren Metallprofilteil 2 und einem äußeren Metallprofilteil 3, beispielsweise aus Aluminium, Aluminiumlegierung oder Stahl gefertigt. Die beiden Metallprofilteile 2, 3 sind durch längsverlaufende Isolierstege stege 4, 5 aus Kunststoff, z.B. Polyesterharz, miteinander verbunden. Die Isolierstege 4, 5 bilden eine wärmedämmende Brücke zwischen den Metallprofilteilen 2, 3.Fig. 1 shows e.g. for the production of windows, Composite profile suitable for doors or facade elements 1 with an inner metal profile part 2 and an outer Metal profile part 3, for example made of aluminum, aluminum alloy or steel. The two metal profile parts 2, 3 are by longitudinal insulating webs webs 4, 5 made of plastic, e.g. Polyester resin, with each other connected. The insulating webs 4, 5 form a heat-insulating Bridge between the metal profile parts 2, 3.

Die Isolierstege 4, 5 ragen mit ihren im Querschnitt schwalbenschwanzförmig ausgebildeten Enden 6 in korrespondierende, längs verlaufende Nuten 7 der Metallprofilteile 2, 3 hinein, in denen sie durch entsprechendes linienoder punktförmiges Anwalzen der diese Nuten 7 begrenzenden Wandschenkel 8 gehalten sind, vgl. auch Fig. 2 und 3.The insulating webs 4, 5 project with their cross section Dovetail-shaped ends 6 in corresponding, longitudinal grooves 7 of the metal profile parts 2, 3 into which they are marked by corresponding lines or punctiform rolling of these grooves 7 delimiting Wall legs 8 are held, see. also FIGS. 2 and 3.

Bei der dargestellten Ausführungsform des Verbundprofils 1 sind zur Verbindung der Metallprofilteile 2, 3 zwei Isolierstege 5 vorgesehen. Bei einfacheren Verbundprofilformen genügt im Prinzip auch nur ein einziger Isoliersteg zur Verbindung der beiden Metallprofilteile. Die beiden in Fig. 1 dargestellten Isolierstege 4, 5 könnten weiterhin auch durch einen oder mehrere Querstege aus dem gleichen Kunststoff miteinander verbunden sein. Die nachstehenden Ausführungen beziehen sich auch auf solche Ausführungsformen von Verbundprofilen bzw. Isolierstegen.In the illustrated embodiment of the composite profile 1 are two insulating webs for connecting the metal profile parts 2, 3 5 provided. With simpler composite profile shapes In principle, even a single insulating bar is sufficient for connecting the two metal profile parts. The two in 1 insulating webs 4, 5 could continue also through one or more crossbars from the same Plastic to be connected. The following Comments also relate to such embodiments of composite profiles or insulating bars.

Wie in Fig. 1 angedeutet und aus Fig. 2 deutlich hervorgeht, ist die die Isolierstege 4, 5 bildende Kunststoffmatrix mit einem Faserverbundskelett 11 kombiniert. Das Faserverbundskelett 11 besteht aus festen, schlecht wärmeleitenden, nicht brennbaren, feuersicheren, hitzebeständigen Fasern, beispielsweise Glasfasern, Kohlenstoffasern oder Fasern aus hitzebeständigem Kunststoff, insbesondere Aramidfasern oder Naturfasern, insbesondere Asbest oder Hanffasern. Der innere Zusammenhalt des Faserverbundskeletts ist dadurch gewährleistet, daß dieses Skelett als Gewebe, Geflecht, Gewirk, Gestrick oder dgl. ausgebildet ist, wobei die Fasern vor Ausbildung des Verbundskeletts zu Fäden oder Garnen vereinigt sein können. Eingebunden in den Kunststoff des Isolierstegs 4, 5 ist das Faserverbundskelett 11 mit seinen längs und quer im Isoliersteg verlaufenden und miteinander verbundenen Fasern in der Lage, hohen Druck-, Schub- und Zugspannungen - auch in Verbindung mit thermischen Belastungen - standzuhalten. Man erhält also durch die Einbettung des Faserverbundskeletts 11 eine deutliche Festigkeitserhöhung des Isolierstegs 4, 5 und eine bessere Sicherung des Verbunds im Verbundprofil 1.As indicated in FIG. 1 and clearly shown in FIG. 2, is the plastic matrix forming the insulating webs 4, 5 combined with a fiber composite skeleton 11. The fiber composite skeleton 11 consists of solid, poorly heat-conducting, non-flammable, fire-proof, heat-resistant Fibers, for example glass fibers, carbon fibers or fibers made of heat-resistant plastic, in particular Aramid fibers or natural fibers, especially asbestos or Hemp fibers. The internal cohesion of the fiber composite skeleton is ensured that this skeleton as Fabric, braid, knitted fabric, knitted fabric or the like is, the fibers before formation of the composite skeleton can be combined into threads or yarns. Involved in the plastic of the insulating web 4, 5 is the fiber composite skeleton 11 with its longitudinal and transverse in the insulating web and interconnected fibers able high compressive, shear and tensile stresses - also in combination with thermal loads - to withstand. You get thus by embedding the fiber composite skeleton 11 a significant increase in the strength of the insulating web 4, 5 and better securing of the composite in composite profile 1.

Wie insbesondere aus Fig. 2 hervorgeht, weist das Faserverbundskelett 11 im Bereich der Nuten 7 der Metallprofilteile 2, 3 profilierte, verdickte Enden 13 auf, die formschlüssig derart in den Nuten 7 verankert sind, daß sie aus diesen auch dann nicht austreten können, wenn der den Isoliertsteg 4 bildende Kunststoff z.B. durch Hitzeeinwirkung oder Rißbildung degeneriert oder generell mechanisch überbelastet ist. Somit stellt das Faserverbundskelett 11 auch in diesem Falle noch einen Zusammenhalt und hängenden Verbund zwischen den Metallprofilteilen 2, 3 sicher, so daß diese sich, z.B. im Brandfall nicht voneinander ablösen können, sondern miteinander unlösbar verhängt bleiben.As can be seen in particular from FIG. 2, the fiber composite skeleton has 11 in the area of the grooves 7 of the metal profile parts 2, 3 profiled, thickened ends 13 on the form-fitting are so anchored in the grooves 7 that they cannot exit from these, even if the Insulating web 4 forming plastic e.g. by exposure to heat or degeneration of cracks or generally mechanical is overloaded. Thus, the fiber composite skeleton 11 in this case too, a cohesion and hanging bond between the metal profile parts 2, 3 safe, so that these e.g. not in the event of fire can replace, but together unsolvable stay curtained.

Bei der in Fig. 2 dargestellten Ausführungsform ist das Faserverbundskelett 11 als gewebtes Band 14 ausgebildet, welches vollständig in die Kunststoffmatrix des Isolierstegs 4 eingebettet ist, so daß der Kunststoff des Isolierstegs das Faserverbundskelett 11 allseits umgibt und durchdringt. Die profilierten, verdickten Enden 13 sind an dem das Faserverbundskelett 11 bildenden Band 14, welches für sich in Fig. 3 dargestellt ist, dadurch hergestellt, daß die Randabschnitte des Bandes wulstartig eingerollt und z.B. durch Vernähen oder Verkleben befestigt sind, so daß sie eine formschlüssige Verankerung in den Nuten 7 der Metallprofilteile 2, 3 bilden. Bei dem in Fig. 3 dargestellten flexiblen, biegeschlaffen Band 14, welches das Rohmaterial für das Faserverbundskelett 11 bildet, könnten die quer verlaufenden Fasern oder Fäden auch schräg zu den längsverlaufenden Fasern oder Fäden ausgerichtet sein.In the embodiment shown in FIG. 2, this is Fiber composite skeleton 11 designed as a woven band 14, which is completely in the plastic matrix of the insulating bridge 4 is embedded so that the plastic of the insulating web surrounds the fiber composite skeleton 11 on all sides and penetrates. The profiled, thickened ends 13 are on the band 14 forming the fiber composite skeleton 11, which is shown by itself in Fig. 3, manufactured that the edge portions of the tape are rolled up like a bead and e.g. are attached by sewing or gluing, so that they have a positive anchoring in the grooves 7 of the Form metal profile parts 2, 3. The one shown in FIG. 3 flexible, slack volume 14, which the Forms raw material for the fiber composite skeleton 11, the transverse fibers or threads could as well aligned obliquely to the longitudinal fibers or threads be.

Die verdickten Enden 13 am Band 14 können auch in anderer Weise ausgebildet werden, beispielsweise durch direktes, textiles Anarbeiten (Anweben, Anstricken) von gegebenenfalls entsprechend profilierten Wülsten an die Ränder des Bandes 14 oder auch durch Anbringung von Glasfaserbündeln oder dgl. an den Rändern des Bandes.The thickened ends 13 on the band 14 can also in other Be trained, for example by direct, textile processing (weaving, knitting) of if necessary correspondingly profiled beads on the edges of the Band 14 or by attaching glass fiber bundles or the like at the edges of the tape.

Das aus dem Band 14 mit den verdickten Randabschnitten 13 bestehende Faserverbundskelett 11 aus hitzebeständigen Fasern ist über die ganze Länge der Isolierstege 4, 5 hinweg in den Nuten 7 der Metallprofilteile 2, 3 formschlüssig verankert.That from the band 14 with the thickened edge sections 13 existing fiber composite skeleton 11 made of heat-resistant Fibers is over the entire length of the insulating webs 4, 5 in the grooves 7 of the metal profile parts 2, 3 positively anchored.

Eine weitere Ausführungsform eines Verbundprofils unterscheidet sich von derjenigen nach Fig. 2 dadurch, daß ein Faserverbundskelett aus hitzebeständigen Fasern nicht im Inneren des Isoliersteges 4, sondern im wesentlichen an dessen Außenseite angeordnet ist, wobei die den Isoliersteg 4 bildende Kunststoffmatrix jedoch das Faserverbundskelett ganz oder teilweise durchdringen kann. Man könnte auch an den beiden Außenseiten des Isolierstegs 4 jeweils Einzelbänder anordnen, die mit wulstartig verdickten Enden, ähnlich den Enden 13 in Fig. 2, in die Nuten 7 der Metallprofilteile 2, 3 eingreifen und hierdurch formschlüssigen Halt geben. Die wulstartig verdickten Enden 13 zweier Einzelbänder 14 lassen sich z.B. mit Hilfe zwischen den Bändern angeordneter, parallel zu deren Längsachse verlaufender Glasfaserbündel erzeugen. Im Falle von seitlichen Einzelbändern können diese durch quer zwischen ihnen verlaufende Fasern oder Fäden miteinander verbunden sein, so daß gewissermaßen ein dreidimensionales, mit Kunststoff gefülltes Gebilde von erhöhter Festigkeit entsteht.Another embodiment of a composite profile differs differs from that of FIG. 2 in that a Fiber composite skeleton made of heat-resistant fibers not in Inside of the insulating web 4, but essentially the outside of which is arranged, the insulating web 4 plastic matrix, however, the fiber composite skeleton can penetrate completely or partially. You could also on the two outer sides of the insulating web 4 in each case Arrange single tapes that have bulged ends, similar to the ends 13 in Fig. 2, in the grooves 7 of the Engage metal profile parts 2, 3 and thereby positive Give hold. The bulged ends 13 two individual belts 14 can e.g. with the help of between the tapes arranged parallel to their longitudinal axis Generate fiber bundles. In the case of side Single tapes can do this by running across them running fibers or threads are connected to one another, so to speak, a three-dimensional, with plastic filled structure of increased strength.

Der durch das Faserverbundskelett 11 verstärkte, die Isolierstege 4, 5 bildende Kunststoff kann zusätzlich weitere Stoffe enthalten: beispielsweise (wie an sich bekannt) einzelne, lose Verstärkungsfasern, insbesondere Glas- oder Kohlenstoffasern, Glaskugeln oder auch vorzugsweise pulvrige Flammschutzmittel, insbesondere Antimontrioxid, Aluminiumhydroxid, Natriumsilikat, chlor-, brom-, phosphorhaltige organische Verbindungen, mikrofasrige Dawsonite und/oder Treibmittel, insbesondere Azodicarbonamid, und/oder Blähstoffe, insbesondere treibmittelhaltige Mikrohohlkugeln aus Silikat, Polypropyl- oder Polyähtylen.The reinforced by the fiber composite skeleton 11, the insulating webs 4, 5 forming plastic can additionally additional Contain substances: for example (as known per se) individual, loose reinforcing fibers, especially glass or Carbon fibers, glass balls or preferably powdery Flame retardants, especially antimony trioxide, aluminum hydroxide, Sodium silicate, containing chlorine, bromine, phosphorus organic compounds, microfiber Dawsonite and / or blowing agents, in particular azodicarbonamide, and / or Bulking agents, especially hollow microspheres containing blowing agents made of silicate, polypropyl or polyethylene.

Für die Herstellung der mit den hitzebeständigen Faserverbundskeletten 11 kombinierten Isolierstege 4, 5 eignen sich insbesondere duroplastische Kunststoffe, z.B. ungesättigte Polyester-, Phenacrylat- oder Vinylester-, Epoxid-, Phenol- oder Harnstoffharze, sowie thermoplastische oder vernetzbare Kunststoffe, z.B. Polyamid-, Polysulfon-, Polyetherketonharze, oder Polyurethan.For the production of with the heat-resistant fiber composite skeletons 11 combined insulating bars 4, 5 are suitable thermosetting plastics, e.g. unsaturated Polyester, phenacrylate or vinyl ester, Epoxy, phenol or urea resins, and thermoplastic or crosslinkable plastics, e.g. Polyamide, polysulfone, Polyether ketone resins, or polyurethane.

Die Bänder 14 können beispielsweise durch Pultrusion, Extrusion oder Koextrusion mit dem die Isolierstege 4, 5 bildenden Kunststoff kombiniert werden.The belts 14 can, for example, by pultrusion, extrusion or coextrusion with which the insulating webs 4, 5 plastic can be combined.

Der durch das Faserverbundskelett 11 vermittelte Fasergehalt kann beispielsweise bis zu 70 Volumen-% der Isolierstege 4, 5 betragen.The fiber content mediated by the fiber composite skeleton 11 can, for example, up to 70% by volume of the insulating webs 4, 5.

Generell ist es bei allen beschriebenen Ausführungsformen auch möglich, die kraft- und formschlüssige Verbindung der Enden der Isolierstege 4, 5, 64 mit den Metallprofilteilen 2, 3 durch zusätzliche Verklebung in an sich bekannter Weise zu verbessern.Generally it is in all described embodiments also possible, the positive and positive connection of the Ends of the insulating webs 4, 5, 64 with the metal profile parts 2, 3 by additional gluing in a manner known per se to improve.
