Abstract

In the case of the composite profile, which is constructed from at least two profiled parts (10) (preferably consisting of aluminium) and from a profiled rail (20) (consisting of thermoplastic synthetic material), once the composite profiled parts have been joined together and, if required, a limb (16) of the undercut groove (12) has been rolled onto the foot (18) of the profiled rail, a laser bombardment is carried out during which the groove web (16) is fused on point-by-point, so that a fused cone (26) is formed which is burnt into the foot (18) of the profiled rail and thus produces a firm positive lock between the composite profiled parts. <IMAGE>

Die Erfindung betrifft ein Verbundprofil aus wenigstens zwei Profilteilen aus Metall, die durch wenigstens eine in Längsrichtung verlaufende, wärmeisolierende Profilschiene verbunden sind, welche mit an ihr in Längsrichtung verlaufenden, in Nuten der Profilteile verankerten Haltestegen versehen ist.The invention relates to a composite profile made up of at least two profile parts made of metal, which by at least one longitudinally extending, heat-insulating Profile rail are connected, which with it extending in the longitudinal direction, in Grooves of the profile parts anchored retaining webs is provided.

Eine feste Verbindung zwischen den Profilteilen aus Metall und der Profilschiene aus Kunststoff erfolgt nach dem Zusammenfügen beispielsweise durch Anrollen des Nutenschenkels an die Profilschiene. Dadurch wird zwar eine ausreichende Querzugfestigkeit erreicht, die Schubfestigkeit derartiger Verbundprofile ist aber nur mangelhaft.A solid connection between the metal profile parts and the Profile rail made of plastic is carried out after joining, for example Roll the groove leg onto the profile rail. This is a sufficient one Reached transverse tensile strength, but the shear strength of such composite profiles is only inadequate.

Der Erfindung liegt die Aufgabe zugrunde, ein Verbundprofil mit verbesserter Schubfestigkeit zu schaffen.The invention is based on the object of a composite profile with improved To create shear strength.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Innenseite eines Nutenstegs punktförmige Schmelzkegel ausgebildet sind, die in den Fuß der Profilschiene eingreifen.This object is achieved according to the invention in that on the inside a groove web point-shaped melting cones are formed in the foot of the Engage the profile rail.

Vorzugsweise werden die Schmelzkegel durch einen Laser ausgebildet.The melting cones are preferably formed by a laser.

Nach dem Zusammenfügen der Verbundprofilteile und ggf. nach Anrollen des Nutenschenkels an den Fuß der Profilschiene erfolgt vorzugsweise an der Außenseite des Nutenschenkels ein Laserbeschuß, bei welchem das Metall punktförmig aufgeschmolzen wird und den Schmelzkegel bildet, der sich in das Kunststoffmaterial der Profilschiene einbrennt. Dadurch erfolgt ein Formschluß zwischen Metallprofil und Profilschiene, so daß zur Trennung der Verbundprofilteile in Schubrichtung ein Abscheren der Schmelzkegel erfolgen müßte.After joining the composite profile parts and, if necessary, after rolling of the groove leg to the foot of the profile rail is preferably carried out on the outside laser bombardment of the groove leg, in which the metal is melted in punctiform fashion and forms the melting cone, which is embedded in the plastic material of the profile rail burns in. This creates a form fit between the metal profile and the profile rail, so that in order to separate the composite profile parts in the thrust direction, the melting cone is sheared off should take place.

Die Abstände der Anschmelzpunkte oder "Nietstellen" können in Abhängigkeit von der geforderten Schubfestigkeit ausgewählt werden.The distances between the melting points or "riveting points" can depend on be selected from the required shear strength.

In Weiterbildung der Erfindung ist im Fuß der Profilschiene ein Metalldraht eingebettet und der sich an der Innenseite des Nutenschenkels ausbildende Schmelzkegel ist mit dem Metalldraht fest verschmolzen, so daß durch den Fuß der Profilschiene "Sperrstifte" ausged Bet werden.In a further development of the invention, a metal wire is in the foot of the profile rail embedded and the melting cone forming on the inside of the groove leg is firmly fused with the metal wire, so that through the foot of the profile rail "Lock pins" can be put out Bet.

Wenn die Energie des Lasers entsprechend ausgewählt wird, kann in-Weiterbildung die feste Verbindung von dem einen Nutenschenkel über den eingelegten Metalldraht zu dem gegenüberliegenden Nutenschenkel erfolgen.If the energy of the laser is selected accordingly, in-training can the fixed connection of one leg of the groove via the inserted metal wire to the opposite groove leg.

Gemäß einer weiteren bevorzugten Ausführungsform ist in dem Fuß der Profilschiene ein mit dieser schubfest verbundener Metallstreifen eingelassen, der Metallstreifen ist an die Außenkontur des Fußes angepaßt und das freie Ende des Streifens ist mit dem Metailprofil.verscbweißt. Der Metallstreifen kann bei der Extrusion der Profils-chiene in Linie in den Fuß eingebettet werden.According to a further preferred embodiment, the is in the foot Profile rail let in a metal strip connected to it in a shear-proof manner, the Metal strip is adapted to the outer contour of the foot and the free end of the The strip is welded to the metal profile. The metal strip can be used at the Extrusion of the profile rail in line to be embedded in the foot.

Das Metallprofilteil 10 ist mit einer hinterschnittenen Nut ausgebildet, die von Nutenschenkeln 14 und 16 eingegrenzt wird. In dieser Nut 12 ist der Fuß 18 einer Profilschiene 20 aus Kunststoff eingeschoben. Der Schenkel 16 der Nut 12 ist vor dem Zusammenbau der Profilteile 10 und 20 nach außen gebogen, so daß zwischen den Außenflächen des Fußes 18 der Profilschiene 20 und den Innenflächen der Nut 12 ein Zwischenraum verbleibt. Der Innenraum der Nut 12 ist etwas größer als der Außenumfang des Fußes 18, damit beim Anrollen des Schenkels 16 die Profilschiene 20 sich ausrichten und die optimale Lage einnehmen kann, so daß die Verbundprofilteile innerhalb der geforderten Toleranzen liegen.The metal profile part 10 is formed with an undercut groove, delimited by groove legs 14 and 16 will. In this groove 12, the foot 18 of a profile rail 20 made of plastic is inserted. The thigh 16 of the groove 12 is bent outward before the assembly of the profile parts 10 and 20, so that between the outer surfaces of the foot 18 of the profile rail 20 and the inner surfaces the groove 12 a gap remains. The interior of the groove 12 is slightly larger than the outer circumference of the foot 18, so that when the leg 16 rolls on, the profile rail 20 can align and take the optimal position, so that the composite profile parts lie within the required tolerances.

Nach dem Anrollen des Schenkels 16 erfolgt in Richtung des Pfeiles 22 ein Beschuß durch einen Laser. Dabei wird der Schenkel 16 punktförmig angeschmolzen. An der Außenseite des Schenkels 16 bildet sich eine Schmelzeintiefung 24 und an der Innenseite ein Schmelzkegel 26, der sich infolge seiner Temperatur in den Fuß 18 der Profilschiene 20 einschmilzt. Der Schmelzkegel 26 erbringt mit dem Fuß 18 der Profilschiene 20 eine Art Vernietung. Der Laserbeschuß erfolgt in Längsrichtung des Verbundprofils in ausgewählten Abständen, so daß die Schubfestigkeit eingestellt werden kann.After the leg 16 has been rolled on, it takes place in the direction of the arrow 22 a bombardment by a laser. The leg 16 is melted on at a point. A melt depression 24 and on is formed on the outside of the leg 16 the inside a melting cone 26, which is due to its temperature in the foot 18 of the profile rail 20 melts. The melting cone 26 produces with the foot 18 the profile rail 20 a kind of riveting. The laser bombardment takes place in the longitudinal direction of the composite profile at selected intervals so that the shear strength is set can be.

Bei der in Fig. 2 gezeigten Ausführungsform ist mit einem Metallprofil 30 aus Aluminium eine Profilschiene 32 aus Kunststoff verbunden.

Nach dem Anrollen beispielsweise des Schenkels 42 an den Fuß 34 erfolgt ein Beschuß mittels eines Lasers in Richtung des Pfeiles 44. Dabei wird der Schenkel 42 punktweise angeschmolzen und es bildet sich ein Schmelzkegel 46 an der Innenseite aus. Die Energie des Lasers wurde derart abgestimmt, daß sich der Schmelzkegel 46 mit dem Aluminiumdraht 36 verbinden kann. Bei geeigneter Wahl des Lasers ist es möglich, daß mittels eines Schmelzkegels 48 eine Verbindung des Aluminiumdrahtes 36 mit der Innenseite des Schenkels 40 erfolgt. Dadurch wird ein durch den Fuß 34 der Profilschiene 32 durchgehender Verriegelungsstift geschaffen.After the leg 42 has been rolled onto the foot 34, for example a shot by means of a laser in the direction of arrow 44. The leg 42 melted on at points and a melting cone 46 forms on the inside the end. The power of the laser was tuned so that the melting cone 46 with the aluminum wire 36 can connect. With a suitable choice of laser it is possible that by means of a melting cone 48 a connection of Aluminum wire 36 with the inside of the leg 40 takes place. This becomes a through the foot 34 of the profile rail 32 continuous locking pin created.
