BeschreibungDescription
Die Erfindung betrifft thermisch getrennte Aluminium-Verbundprofile für Fenster und Türen, wobei die Verbundprofile aus einer Aluminium-Innenschale und einer Aluminium-Außenschale bestehen, die durch mindestens zwei Dämmstege voneinander getrennt sind, sodaß Innen- und Außenschale parallel und voneinander beabstandet angeordnet sind. Durch diese Anordnung erstreckt sich in Verbundprofil-Achsrichtung ein Hohlraum, der von der Aluminium-Außenschale und Aluminium-Innenschale einerseits und den diese Aluminiumprofile trennenden Dämmstegen andererseits gebildet wird. Die Verbindung zwischen den Aluminiumschalen und den dazwischen angeordneten Dämmstegen besteht vorzugsweise aus einem durch Einrollen erzeugten Formschluß zwischen den freien Enden der Dämmstege und entsprechenden den Aluminiumprofilen angeformten nasenartigen Vorsprüngen.The invention relates to thermally separated aluminum composite profiles for windows and doors, wherein the composite profiles consist of an aluminum inner shell and an aluminum outer shell, which are separated from one another by at least two insulating webs, so that the inner and outer shells are arranged parallel and spaced from one another. This arrangement results in a cavity extending in the axial direction of the composite profile, which is formed by the aluminum outer shell and aluminum inner shell on the one hand and the insulating webs separating these aluminum profiles on the other. The connection between the aluminum shells and the insulating webs arranged between them preferably consists of a positive connection, created by rolling, between the free ends of the insulating webs and corresponding nose-like projections molded onto the aluminum profiles.
Derartige Verbundprofile sind der Fachwelt seit langem bekannt, wobei eine verbreitete Ausführungsform dadurch charakterisiert ist, daß die Dämmstege aus glasfaserverstärktem Polyamid bestehen. Die erwähnten Dämmstege dienen der Reduktion der Wärmeleitung durch die Aluminium-Profile von der Raumseite zur Wetterseite und somit der Verringerung von unerwünschtem Wärmeverlust.Such composite profiles have been known to experts for a long time, with a common design being characterized by the fact that the insulating bars are made of glass fiber reinforced polyamide. The insulating bars mentioned serve to reduce heat conduction through the aluminum profiles from the room side to the weather side and thus reduce unwanted heat loss.
Es ist bekannt, daß die thermische Trennung der Aluminium-Profile, die durch Dämmstege aus glasfaserverstärktem Polyamid erzielt wird, durchaus verbesserungswürdig ist.It is known that the thermal separation of the aluminum profiles, which is achieved by insulating bars made of glass fiber reinforced polyamide, is definitely in need of improvement.
Die Aufgabe der vorliegenden Erfindung besteht darin, die thermische Trennung bekannter Aluminium-Verbundprofile zu verbessern indem die Wärmeleitfähigkeit der Dämmstege herabgesetzt wird.The object of the present invention is to improve the thermal separation of known aluminum composite profiles by reducing the thermal conductivity of the insulating webs.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Glasfaserverstärkung des , Polyamids durch einen nicht mineralischen Zuschlag, beispielsweise Carbonfaser, ersetzt wird.The object is achieved according to the invention in that the glass fiber reinforcement of the polyamide is replaced by a non-mineral additive, for example carbon fiber.
Durch den erfindungsgemäßen Einsatz von nicht mineralischen Fasern anstelle bisher gebräuchlicher Glasfasern wird die vergleichsweise geringere Wärmeleitfähigkeit gegenüber Mineralfasern vorteilhaft zur Herabsetzung des Wärmedurchgangskoeffizienten entsprechender Aluminium-Verbundprofile ausgenützt.By using non-mineral fibers instead of the previously used glass fibers, the comparatively lower thermal conductivity compared to mineral fibers is advantageously used to reduce the thermal transmittance of corresponding aluminum composite profiles.
Darüberhinaus ergeben sich Vorteile aus weiteren materialspezifischen Eigenschaften des erfindungsgemäß eingesetzten nicht mineralischen Werkstoffes, beispielsweise Carbon. Vergleichsweise höhere Festigkeitswerte, insbesondere die höhere Zugfestigkeit, gestatten eine geringere Dimensionierung als bei bekannten glasfaserverstärkten Dämmprofilen. Bei gleicher Zugfestigkeit können die Dämmstege mit reduzierter Wandstärke ausgeführt werden, was letztendlich auch zu Materialeinsparungen führt.In addition, advantages arise from other material-specific properties of the non-mineral material used according to the invention, for example carbon. Comparatively higher strength values, in particular the higher tensile strength, allow smaller dimensions than with known glass fiber reinforced insulation profiles. With the same tensile strength, the insulation bars can be designed with a reduced wall thickness, which ultimately also leads to material savings.
Die Reduzierung der Wandstärke erfindungsgemäßer Polyamid-Dämmstege mit Carbonfaser-Verstärkung wirkt sich durch den geringeren Materialquerschnitt auch günstig auf die angestrebte Dämmwirkung aus.The reduction in the wall thickness of the inventive polyamide insulation bars with carbon fiber reinforcement also has a positive effect on the desired insulation effect due to the smaller material cross-section.
Fig. 1 zeigt einen Vertikalschnitt eines Fensters, dessen Rahmen und Flügel im wesentlichen aus stranggepreßten Aluminiumprofilen bestehen, wobei die Rahmen- und Flügelprofile aus thermisch getrennten Aluminium-Verbundprofilen bestehen. Die Innenschale 2 und die Außenschale 2' des Flügelprofils sind durch mindestens zwei Dämmstege 1 thermisch getrennt. Ebenso sind die Außenschale 3 und die Innenschale 3'des Rahmenprofils durch mindestens zwei Dämmstege 1 thermisch getrennt.Fig. 1 shows a vertical section of a window whose frame and sash consist essentially of extruded aluminum profiles, whereby the frame and sash profiles consist of thermally separated aluminum composite profiles. The inner shell 2 and the outer shell 2' of the sash profile are thermally separated by at least two insulating bars 1. The outer shell 3 and the inner shell 3' of the frame profile are also thermally separated by at least two insulating bars 1.
Wie aus Fig. 1 ersichtlich ist der erfindungsgemäße Dämmsteg 1 im Innenbereich der Dämmzone 4 mit geringerem Querschnitt ausgeführt als im Bereich der freien Enden derAs can be seen from Fig. 1, the insulating web 1 according to the invention is designed with a smaller cross-section in the inner area of the insulating zone 4 than in the area of the free ends of the

Dämmstege 1. Diese Querschnitt-Reduzierung wird durch die erfindungsgemäße Verwendung t von Carbonfasern anstelle von Glasfasern zur Armierung der Dämmstege, wie es bei bekannten Dämmstegen nach dem Stand der Technik üblich ist, ermöglicht, was letztlich die angestrebte Verbesserung der Dämmwirkung erfindungsgemäßer Dämmstege 1 bewirkt.Insulating webs 1. This cross-sectional reduction is made possible by the inventive use of carbon fibers instead of glass fibers for reinforcing the insulating webs, as is usual with known insulating webs according to the state of the art, which ultimately brings about the desired improvement in the insulating effect of insulating webs 1 according to the invention.
In Fig. 2 ist ein Ausführungsbeispiel eines erfindungsgemäßen Dämmsteges im Schnitt dargestellt, an dem die wesentlichen Vorteile erläutert werden, die durch die Verwendung von Carbonfasern anstelle von Glasfasern zur Dämmprofil-Verstärkung erreicht werden. Die Darstellung des Dämmsteges 1 gemäß Fig. 2 zeigt die hammerartige Querschnittform der freien Enden 5, 5' des Dämmsteges 1, die in Zusammenwirken mit den Vorsprüngen 8 und 9 , die den Aluminium-Profilschalen an geeigneten Stellen angeformt sind, die formschlüssige, stabile Verbindung der Dämmstege 1 mit den Aluminium-Profilschalen 2,2' und 3,3' ermöglichen.In Fig. 2, an embodiment of an insulating web according to the invention is shown in section, which explains the essential advantages achieved by using carbon fibers instead of glass fibers to reinforce the insulating profile. The representation of the insulating web 1 according to Fig. 2 shows the hammer-like cross-sectional shape of the free ends 5, 5' of the insulating web 1, which, in conjunction with the projections 8 and 9, which are molded onto the aluminum profile shells at suitable points, enable the positive, stable connection of the insulating webs 1 to the aluminum profile shells 2, 2' and 3, 3'.
Ausgehend von den beiden freien Enden 5,5' des beispielhaft dargestellten Dämmsteges 1 erstrecken sich jeweils in Achsrichtung zum Mittelteil 7 verlaufende Steg-Abschnitte, die in der genannten Richtung eine Querschnittverjüngung 6,6' aufweisen, bis schließlich der Mittelteil 7 des Dämmsteges 1 die geringste Querschnittabmessung erreicht. Die durch die erfindungsgemäße Carbonfaserverstärkung ermöglichte Querschnittverjüngung 6, 6' bis auf den Querschnitt des Mittelteiles 7 führt zu der angestrebten erhöhten Dämmwirkung der Dämmstege 1 und somit zur erwünschten Verbesserung des Wärmedurchgangskoeffizienten kR der in Fig. 1 beispielhaft dargestellte Aluminium-VerbundprofileStarting from the two free ends 5,5' of the insulating web 1 shown as an example, web sections extend in the axial direction to the middle part 7, which have a cross-sectional taper 6,6' in the direction mentioned, until finally the middle part 7 of the insulating web 1 reaches the smallest cross-sectional dimension. The cross-sectional taper 6, 6' made possible by the carbon fiber reinforcement according to the invention down to the cross section of the middle part 7 leads to the desired increased insulating effect of the insulating webs 1 and thus to the desired improvement in the heat transfer coefficient k R of the aluminum composite profiles shown as an example in Fig. 1
