Description

Die Erfindung betrifft ein Verbundprofil aus zwei Metallprofilteilen und zwei diese Teile miteinander verbindenden Kunststoffisolierstegen, die in Nuten der Metallprofilteile gehalten sind, wobei die Innenseiten der Metallprofilteile und der Kunststoffisolierstege eine in Längsrichtung des Verbundprofils durchgehend verlaufende Kammer begrenzen, die mit einem wärmedämmenden Material gefüllt ist.The invention relates to a composite profile made of two metal profile parts and two plastic insulating webs connecting these parts, which are held in grooves of the metal profile parts, the inside of the metal profile parts and the plastic insulating webs delimiting a continuous chamber running in the longitudinal direction of the composite profile, which is filled with a heat-insulating material.

Bei einem bekannten Verbundprofil dieser Art (FR-PS 23 03 228) wird die in Längsrichtung des Verbundprofils verlaufende Kammer mit flüssigem Polyurethan-Hartschaummaterial gefüllt, das nach seiner Expansion und Aushärtung die Kunststoffisolierstege fest mit den Metallprofilteilen verspannt. Gleichzeitig dient der in der Kammer gebildete Hartschaum naturgemäß auch der Wärmedämmung, indem er eine Wärmekonvektion und eine Wärmeabstrahlung innerhalb der Kammer verhindert.In a known composite profile of this type (FR-PS 23 03 228), the chamber running in the longitudinal direction of the composite profile is filled with liquid rigid polyurethane material which, after its expansion and curing, firmly clamps the plastic insulating webs to the metal profile parts. At the same time, the rigid foam formed in the chamber naturally also serves as thermal insulation by preventing heat convection and heat radiation within the chamber.

Abgesehen davon, daß durch die Verspannung der Kunststoffisolierstege durch das Schaummaterial die Maßhaltigkeit des Verbundprofils beeinträchtigt sein kann, ist es schwierig, das zunächst flüssige, relativ zähe Hartschaummaterial gleichmäßig in die Kammer der Verbundprofile einzubringen, wenn diese üblicherweise eine Länge zwischen 6 und 8 m haben. Außerdem trägt das Hartschaummaterial zur Schubsteifigkeit des Verbundprofils nichts bei.Apart from the fact that the dimensional stability of the composite profile can be impaired by the tensioning of the plastic insulating webs by the foam material, it is difficult to introduce the initially liquid, relatively tough rigid foam material evenly into the chamber of the composite profiles, if these usually have a length of between 6 and 8 m . In addition, the rigid foam material does not contribute to the shear stiffness of the composite profile.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Verbundprofil so auszubilden, daß das wärmedämmende Material auf einfache Weise in die längs verlaufende Kammer eingeführt werden kann und die Schubsteifigkeit des Verbundprofils erhöht.It is an object of the invention to design a generic composite profile so that the heat-insulating material can be introduced into the longitudinal chamber in a simple manner and increases the shear rigidity of the composite profile.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß als wärmedämmendes Material in die Kammer ein Schüttgut in Form kugeliger Körner aus Mineral- oder Kunststoff sowie zusammen mit diesen Körnern ein klebendes Bindemittel in die Kammer eingefüllt ist, das die Körner untereinander sowie mit den Innenseiten der Metallprofilteile und der Kunststoffisolierstege fest und schubsteif verbindet, und das Bindemittel ein aushärtbares Harz ist.The object is achieved in that a bulk material in the form of spherical grains made of mineral or plastic and together with these grains an adhesive binder is filled into the chamber as a heat insulating material, the grains with each other and with the inside of the metal profile parts and the plastic insulating bars connect firmly and shear-resistant, and the binder is a hardenable resin.

Die Figur 1 zeigt ein z. B. für die Herstellung von Fenstern, Türen, Fassadenelementen oder dergleichen geeignetes Verbundprofil 1 mit einem inneren Metallprofilteil 2 und einem äußeren Metallprofilteil 3, beide z. B. aus Aluminium oder Aluminiumlegierung gefertigt. Die beiden Metallprofilteile 2, 3 sind durch längs verlaufende Kunststoffisolierstege 4, 5, z. B. aus glasfaserverstärktem Polyamid miteinander verbunden. Die Kunststoffisolierstege 4, 5 bilden eine wärmedämmende Brücke zwischen den Metallprofilteilen 2, 3.Figure 1 shows a z. B. for the production of windows, doors, facade elements or the like suitable composite profile 1 with an inner metal profile part 2 and an outer metal profile part 3, both z. B. made of aluminum or aluminum alloy. The two metal profile parts 2, 3 are by longitudinal plastic insulating webs 4, 5, z. B. made of glass fiber reinforced polyamide. The plastic insulating webs 4, 5 form a heat-insulating bridge between the metal profile parts 2, 3.

Die Kunststoffisolierstege 4, 5 ragen mit ihren im Querschnitt schwalbenschwanzförmig ausgebildeten Enden 6 in entsprechend ausgebildete, längs verlaufende Nuten 7 der Metallprofilteile 2, 3 hinein, in denen sie durch entsprechendes Anpressen der diese Nuten 7 begrenzenden Wandschenkel 8 gehalten sind. Dabei bildet sich im fertigen Verbundprofil zwischen den Innenseiten der Metallprofilteile 2, 3 und der Kunststoffisolierstege 4, 5 eine in Längsrichtung des Verbundprofils durchgehend verlaufende Kammer 9 aus.The plastic insulating webs 4, 5 protrude with their dovetail-shaped ends 6 in cross-section into appropriately designed, longitudinal grooves 7 of the metal profile parts 2, 3, in which they are held by pressing the wall limbs 8 delimiting these grooves 7 accordingly. In this way, a chamber 9 running continuously in the longitudinal direction of the composite profile is formed in the finished composite profile between the inner sides of the metal profile parts 2, 3 and the plastic insulating webs 4, 5.

In diese Kammer 9 ist als wärmedämmendes Material ein Schüttgut in Form kugeliger Körner 11 eingebracht, das die Kammer 9 über die gesamte Länge des Verbundprofils 1 anfüllt. Da die Körner 11 schüttfähig sind, ist ihre Einbringung von einem der Enden des Verbundprofils 1 her einfach durchzuführen.A bulk material in the form of spherical grains 11 is introduced into this chamber 9 as the heat-insulating material and fills the chamber 9 over the entire length of the composite profile 1. Since the grains 11 are pourable, they can be introduced easily from one of the ends of the composite profile 1.

Das die Kammer 9 dicht ausfüllende, aus den kugeligen Körnern 11 bestehende Füllmaterial verhindert eine störende Wärmekonvektionsströmung in der Kammer 9 sowie eine Wärmestrahlung zwischen den Kammerwänden.The filling material, which tightly fills the chamber 9 and consists of the spherical grains 11, prevents a disruptive heat convection flow in the chamber 9 and heat radiation between the chamber walls.

Die ein übliches Granulat bildenden, kugeligen Körner 11 bestehen vorzugsweise aus einem Mineral- oder Kunststoff. Zur Verminderung ihres Gewichtes können die Körner 11 als poröse oder als Hohlkörper ausgebildet sein.The spherical grains 11 forming a conventional granulate preferably consist of a mineral or plastic. To reduce their weight, the grains 11 can be designed as porous or as hollow bodies.

Die Körner 11 können beispielsweise aus geschäumtem Kunststoff bestehen oder aus Silikat, Ton oder Silikat-Ton-Gemischen. Besonders bevorzugt sind Körner 11 aus Blähton.The grains 11 can for example consist of foamed plastic or of silicate, clay or silicate-clay mixtures. Grains 11 made of expanded clay are particularly preferred.

Grundsätzlich können die Körner 11 lose in die Kammer 9 eingebracht werden, wenn durch entsprechende Verschlüsse an den Stirnseiten der Verbundprofile ihr Herausfallen aus der Kammer 9 verhindert wird.In principle, the grains 11 can be introduced loosely into the chamber 9 if they are prevented from falling out of the chamber 9 by appropriate closures on the end faces of the composite profiles.

Günstiger ist es, zusammen mit den Körnern 11 ein Bindemittel in die Kammer einzufüllen, das die Körner 11 untereinander sowie mit den Innenseiten der Metallprofilteile 2, 3 und der Isolierstege 4, 5 fest verbindet. Ein Verbundprofil mit einem derartigen Füllmaterial in der Kammer 9 ist in Figur 2 und 3 dargestellt. Dabei ist angenommen, daß das die Körner 11 umhüllende Bindemittel 12 ein schäumbarer Klebstoff ist. Die Figur 2 zeigt das Verbundprofil vor dem Aufschäumen, die Figur 3 zeigt das Verbundprofil nach dem Aufschäumen des Klebstoffes, wobei die Körner 11 mit diesem Klebstoff jeweils beschichtet sind.It is cheaper to fill the chamber together with the grains 11, which firmly connects the grains 11 to one another and to the inside of the metal profile parts 2, 3 and the insulating webs 4, 5. A composite profile with such a filling material in the chamber 9 is shown in Figures 2 and 3. It is assumed that the binder 12 enveloping the grains 11 is a foamable adhesive. FIG. 2 shows the composite profile before foaming, FIG. 3 shows the composite profile after foaming of the adhesive, the grains 11 being coated with this adhesive in each case.

Bei der abgewandelten Ausführungsform eines Verbundprofils gemäß Figur 4 und 5 sind die Körner 11 nicht mit einem Bindemittel beschichtet. Vielmehr ist ein Bindemittel 13, wiederum in Form eines schäumbaren Klebstoffes, separat von den Körner 11 in die Kammer 9 eingebracht (Figur 4), welches nach dem Aufschäumen (Figur 5) die Körner miteinander sowie mit den Innenseiten der Metallprofilteile 2, 3 und der Isolierstege 4, 5 fest verhaftet.In the modified embodiment of a composite profile according to FIGS. 4 and 5, the grains 11 are not coated with a binder. Rather, a binder 13, again in the form of a foamable adhesive, is introduced separately from the grains 11 into the chamber 9 (FIG. 4), which, after foaming (FIG. 5), the grains with one another and with the inner sides of the metal profile parts 2, 3 and Insulating bars 4, 5 firmly arrested.

Das Bindemittel 12, 13 kann auch ein aushärtbares Harz oder ein aushärtbarer Kunststoff sein.The binder 12, 13 can also be a curable resin or a curable plastic.

Durch die beschriebene Verbindung der Körner 11 untereinander und mit den Wänden der Kammer 9 sind die Körner in letzterer fixiert.By the described connection of the grains 11 with each other and with the walls of the chamber 9, the grains are fixed in the latter.

Das Bindemittel kann zur Hervorrufung seiner Bindefunktion durch Druck, Temperatur, Feuchte oder energiereiche Strahlen aktiviert werden.The binding agent can be activated to produce its binding function by pressure, temperature, humidity or high-energy rays.

Als Bindemittel eignen sich beispielsweise Kunststoffe wie Polyester, Phenol-Vinyl- oder Epoxydharze mit entsprechenden Härtern, Beschleunigern, Inhibitoren und/oder Thixotropiermitteln.Suitable binders are, for example, plastics such as polyester, phenol-vinyl or epoxy resins with appropriate hardeners, accelerators, inhibitors and / or thixotropic agents.

Das Bindemittel kann in aufgeschlagener Form als Schaum vorliegen oder ein Treibmittel enthalten, welches zu einem Aufschäumen des Bindemittels in der Kammer 9 führt. Geeignete Treibmittel sind CO² oder t-Butylhydrazinchlorid mit Eisen-III-Chlorid.The binder can be opened in the form of a foam are present or contain a blowing agent which leads to foaming of the binder in the chamber 9. Suitable blowing agents are CO² or t-butylhydrazine chloride with ferric chloride.

Die Bindemittel 12, 13, z. B. Harze, können so eingestellt werden, daß über die kugeligen Körner 11 eine feste, schubsteife Verbindung zwischen den Metallprofilteilen 2, 3 und den Kunststoffisolierstegen 4, 5 erreicht wird. Auf diese Weise brauchen die Isolierstege 4, 5 keine tragende, statische Funktion mehr auszuüben, da diese von dem aus den Körnern 11 und von den Bindemitteln 12, 13 bestehenden Verbundkörper übernommen wird. Daher können insbesondere die Kunststoffisolierstege 4, 5 mit einer geringeren Wandstärke ausgebildet werden, wodurch wiederum weniger Wärme durch diese Stege von dem einen zum anderen Metallprofilteil 2, 3 fließen kann. Auch ist es aufgrund des von den Körnern 11 und den Bindemitteln 12, 13 gebildeten Verbundkörpers nicht mehr erforderlich, die Kunststoffisolierstege 4, 5 besonders fest in den Nuten 7 zu verankern, wozu bisher diese Nuten inwendig mit Hilfe eines teueren Verfahrens gerändelt oder die Wandschenkel 8 der Nuten 7 besonders fest an die Enden 6 der Kunststoffisolierstege 4, 5 angepreßt werden mußten.The binders 12, 13, e.g. B. Resins can be adjusted so that a firm, shear-resistant connection between the metal profile parts 2, 3 and the plastic insulating webs 4, 5 is achieved via the spherical grains 11. In this way, the insulating webs 4, 5 no longer have to perform a load-bearing, static function, since this is carried out by the composite body consisting of the grains 11 and the binders 12, 13. Therefore, in particular, the plastic insulating webs 4, 5 can be formed with a smaller wall thickness, which in turn means that less heat can flow through these webs from one metal profile part 2, 3 to the other. Also, due to the composite body formed by the grains 11 and the binders 12, 13, it is no longer necessary to anchor the plastic insulating webs 4, 5 particularly firmly in the grooves 7, for which purpose these grooves have previously been knurled internally with the aid of an expensive method or the wall legs 8 the grooves 7 had to be pressed particularly firmly onto the ends 6 of the plastic insulating webs 4, 5.

Es ist möglich, die Kammer 9 - im Gegensatz zu Figur 2 und 4 - von vornherein dicht und vollständig mit den Körnern 11 und den Bindemitteln 12, 13 zu füllen, wobei die Körner 11 beispielsweise mit Bindemittel in Form eines aktivierbaren Klebstoffes beschichtet sein können. In keinem Fall, also auch nicht bei Verwendung eines schäumbaren Bindemittels, entsteht in der Kammer 9 ein Innnendruck, der die Kunststoffisolierstege 4, 5 deformieren und zu Maßveränderungen des Verbundprofils 1 führen könnte.In contrast to FIGS. 2 and 4, it is possible to fill the chamber 9 tightly and completely from the start with the grains 11 and the binders 12, 13, the grains 11 being able to be coated, for example, with binders in the form of an activatable adhesive. In no case, ie not even when using a foamable binder, does the chamber 9 have an internal pressure which Plastic insulating webs 4, 5 deform and could lead to dimensional changes in the composite profile 1.

Insgesamt ist das Einbringen der kugeligen Körner 11 zusammen mit dem Bindemittel 12, 23 ein Handling, das einfach, schnell und kostensparend ist.Overall, the introduction of the spherical grains 11 together with the binder 12, 23 is handling that is simple, quick and cost-saving.

Bei der in Figur 6 und 7 dargestellten, abgewandelten Ausführungsform wird ein modifizierter Isoliersteg in Form einer Rinne 14 verwendet, die dadurch gebildet wird, daß man zwei im Abstand voneinander angeordnete Kunststoffisolierstege 4, 5 einstückig mit einer Bodenwand 15, z. B. durch Extrusion, verbindet. In diese Rinne 14 werden die mit klebfähigem Bindemittel 12 beschichteten, kugeligen Körner 11 bis oben hin eingefüllt. Anschließend wird das z. B. aus einem Harz und einem Härter bestehende Bindemittel ausgehärtet, so daß ein steifer Verbundkörper entsteht. Dieser wird in der aus Figur 7 ersichtlichen Weise zwischen die Metallprofilteile 2, 3 eingeschoben. Anschließend wird das Verbundprofil durch Anwalzen der Wandschenkel 8 an die Rinne 14 ausgebildet.In the modified embodiment shown in Figures 6 and 7, a modified insulating web in the form of a groove 14 is used, which is formed by integrating two spaced apart plastic insulating webs 4, 5 with a bottom wall 15, for. B. by extrusion. The spherical grains 11 coated with adhesive binder 12 are filled into this channel 14 up to the top. Then the z. B. cured from a resin and a hardener binder, so that a rigid composite body is formed. This is inserted between the metal profile parts 2, 3 in the manner shown in FIG. 7. The composite profile is then formed by rolling the wall legs 8 onto the channel 14.

Bei der in Figur 6 und 7 dargestellten, rinnenförmigen Ausführungsform der Erfindung könnten auch die oberen, freien, schwalbenschwanzförmigen Enden 6 der Isolierstege 4, 5 durch eine Boden- oder Deckwand 15 einstückig verbunden sein, so daß insgesamt ein Hohlkammerprofil entsteht, welches die Kammer 9 umschließt. Dieses Hohlkammerprofil wird dann statt der Rinne 14 mit den Metallprofilteilen 2, 3 in der aus Figur 7 ersichtlichen Weise fest verbunden. In das Hohlkammerprofil können, z. B. vorher, die Körner 11 und gegebenenfalls das Bindemittel 12, 13 eingefüllt werden.In the channel-shaped embodiment of the invention shown in FIGS. 6 and 7, the upper, free, dovetail-shaped ends 6 of the insulating webs 4, 5 could also be connected in one piece by a bottom or top wall 15, so that overall a hollow chamber profile is created, which defines the chamber 9 encloses. This hollow chamber profile is then firmly connected to the metal profile parts 2, 3 in the manner shown in FIG. 7 instead of the channel 14. In the hollow chamber profile, for. B. before, the grains 11 and optionally the binder 12, 13 filled will.

Zur weiteren Verstärkung des aus den Körnern 11 und dem Bindemittel 12, 13 bestehenden "Isolierkernes" können den verwendeten Harzen, aus denen die Körner 11 und die Bindemittel 12, 13 bestehen können, auch Verstärkungsfasern, beispielsweise in Form von Glas- oder Kohlenstoffasern sowie auch sogenannte "Rovings" beigegeben werden.To further reinforce the "insulating core" consisting of the grains 11 and the binder 12, 13, the resins used, from which the grains 11 and the binder 12, 13 can be made, also reinforcing fibers, for example in the form of glass or carbon fibers, and also so-called "rovings" can be added.

Bei den dargestellten Ausführungsformen weisen die Verbundprofile 1 immer nur eine einzige, längs durchgehende Kammer 9 auf. Die Erfindung läßt sich selbstverständlich auch auf solche Verbundprofile anwenden, bei denen zwischen den Metallprofilteilen 2, 3 mehrere solcher Kammern 9 neben- oder übereinander vorgesehen sind, beispielsweise durch Verwendung mehrerer oder spezifisch geformter Kunststoffisolierstege.In the illustrated embodiments, the composite profiles 1 always have only a single, longitudinally continuous chamber 9.
