Abstract
Description
Die vorliegende Erfindung bezieht sich auf einen leiterförmigen Isoliersteg für ein Verbundprofil für Fenster-, Türen- und Fassadenelemente und ein Verbundprofil für Fenster-, Türen- und Fassadenelemente.The present invention relates to a ladder-shaped insulating web for a composite profile for window, door and facade elements and a composite profile for window, door and facade elements.
Isolierstege für Verbundprofile für Fenster-, Türen- und Fassadenelemente und Verbundprofile für Fenster-, Türen- und Fassadenelemente sind z.B. aus der
Aus der
Es ist eine Aufgabe der Erfindung, einen Isoliersteg (thermischen Trennsteg) für ein Verbundprofil, der ausreichend hohe Schubsteifigkeit bei verbesserter thermischer Trennung ermöglicht, und ein derart verbessertes Verbundprofil anzugeben.It is an object of the invention to provide an insulating web (thermal barrier web) for a composite profile which allows sufficiently high shear stiffness with improved thermal separation, and such an improved composite profile.
Diese Aufgabe wird gelöst durch einen Isoliersteg nach Anspruch 1 bzw. ein Verbundprofil nach Anspruch 5.This object is achieved by an insulating web according to claim 1 or a composite profile according to claim 5.
Weiterbildungen der Erfindung sind in den Unteransprüchen angebeben.Further developments of the invention are indicated in the subclaims.
Es wird ein Verbundprofil, insbesondere ein Metallverbundprofil angeben, bei dem die außen gelegenen Profilteile (z.B. Außenschale und Innenschale) aus z.B. Metall mittels einem oder mehreren der Isolierstege aus Kunststoff verbunden sind. Eine Relativbewegung in Längsrichtung wird durch die hohe Schubsteifigkeit (Ausprägung der Sprossen in Breite, Dicke, Länge, Anzahl) begrenzt bzw. verhindert.It will specify a composite profile, in particular a metal composite profile, in which the outer profile parts (eg outer shell and inner shell) made of metal, for example, are connected by means of one or more of the insulating webs made of plastic. A relative movement in the longitudinal direction is limited or prevented by the high shear stiffness (expression of the rungs in width, thickness, length, number).
Vorteilhaft werden die Isolierstege zuerst aus einem geeigneten Material z.B. durch Extrusion gefertigt als Profilteile mit konstantem Querschnitt über die Länge. Die Sprossen bzw. genauer die Ausnehmungen werden danach durch eine Bearbeitung wie eine spanende Bearbeitung (z.B. Fräsen), Schneiden (wie z.B. Laserschneiden, Wasserstrahlschneiden, etc.), Stanzen, usw. hergestellt. Das ausgenommene Material kann recycelt werden.Advantageously, the insulating bars are first made of a suitable material, e.g. manufactured by extrusion as profile parts with constant cross section over the length. The rungs, more specifically the recesses, are then produced by machining such as machining (e.g., milling), cutting (such as laser cutting, water jet cutting, etc.), punching, etc. The reclaimed material can be recycled.
Die Metallprofilteile werden fest und damit unverlierbar mit dem Isoliersteg verbunden.The metal profile parts are firmly and thus captively connected to the insulating bar.
Zur Abdeckung der Zwischenräume zwischen den Sprossen sind die Isolierstege mit Abdeckprofilen versehen. Die Abdeckprofile können z.B. angeclipst, angeklebt, anextrudiert, auflaminiert, etc. werden. Es ist auch zusätzlich möglich, die Zwischenräume zwischen den Leitersprossen mit einem Material, das einen niedrigeren Wärmeleitungskoeffizienten als das Material der Sprossen aufweist, auszufüllen. Die Funktion solcher Abdeckprofile etc. ist einerseits der Schutz vor dem Eindringen von Feuchtigkeit, andererseits der Schutz des Innenkerns. Mit den Abdeckprofilen kann der Feuchtigkeitsschutz sichergestellt werden. Zusätzlich können dekorative Elemente angebracht werden. Z.B. kann das Abdeckprofil elektrisch leitfähig ausgeführt werden und damit bei der Pulverlackierung die Farbe der Metallprofile annehmen. Ebenfalls ist eine Bedruckung möglich.To cover the spaces between the rungs the insulating bars are provided with cover profiles. The cover profiles may e.g. clipped, glued, extruded, laminated, etc. It is also possible in addition to fill the spaces between the ladder rungs with a material having a lower coefficient of thermal conductivity than the material of the rungs. The function of such cover profiles, etc., on the one hand the protection against the ingress of moisture, on the other hand, the protection of the inner core. With the cover profiles, the moisture protection can be ensured. In addition, decorative elements can be attached. For example, the cover profile can be made electrically conductive and thus accept the color of the metal profiles in the powder coating. Also a printing is possible.
Ein Vorteil ist, dass die U-Werte (Wärmeleitungseigenschaften) der Isolierstege durch das Anbringen der Abdeckprofile/Füllungen, insbesondere der Abdeckprofile, nicht übermäßig verschlechtert werden.One advantage is that the U-values (thermal conduction properties) of the insulating bars are not excessively worsened by the attachment of the cover profiles / fillings, in particular the cover profiles.

Als Material für die Isolierstegkörper kommen Hart-PVC, PA, PET, PPT, PA/PPE, ASA. PA66 in Frage, und bevorzugt wird PA66GF25. Als Schäume kommen Schäume aus Duroplasten wie PU mit entsprechender Dichte in Frage, bevorzugt Schäume niedriger Dichte (0,01 bis 0,3 kg/l).As material for the Isolierstegkörper come hard PVC, PA, PET, PPT, PA / PPE, ASA.

Frühere Anwendungen von leiterartigen Profilen zielten darauf ab, eine niedrige Schubfestigkeit (hohe Längsbeweglichkeit) zu erzielen. In einer anderen Anwendung wurden Ausnehmungen nur vorgesehen, um bei einer bekanntermaßen sehr stark leitenden Metalleinlage die Wärmeleitung zu verringern.Earlier applications of ladder-type profiles aimed to achieve low shear strength (high longitudinal mobility). In another application, recesses have been provided only to reduce heat conduction in a known highly conductive metal insert.
Bei den bevorzugten Ausführungsformen mit teilweise anextrudierten und auf der anderen Seite angeclipsten oder mit vollständig angeclipsten Deckeln ,jeweils zur Abdeckung der Ausnehmungen, hat sich insbesondere für die ganz oder teilweise angeclipsten Deckel überraschender Weise herausgestellt, dass diese die sogenannten U-Werte, d.h. die Wärmetrennungseigenschaften der Isolierstege gegenüber nicht abgedeckten Versionen nur unwesentlich beeinflussen. So haben Versuche mit einem massiven Steg mit einem Querschnitt der in

Auch wenn der Grund dieses Effektes nicht ganz klar ist, so liegt er doch vermutlich in der Ausgestaltung der Clipsanschlüsse und damit des stark behinderten Wärmeübertragungsweges durch den Deckel.Although the reason of this effect is not very clear, it probably lies in the design of the clip connections and thus the strongly impeded heat transfer path through the lid.
