Description
Die Erfindung bezieht sich auf einen Isoliersteg aus wärmedämmendem Material, insbesondere Kunststoffmaterial, für Verbundprofile von Fenster- oder Türrahmen, Fassadenkonstruktionen o. dgl. gemäß dem Oberbegriff des Anspruches 1.The invention relates to an insulating web of heat-insulating material, in particular plastic material, for composite profiles of window or door frames, facade constructions o. The like. According to the preamble of

Schließlich sind aus der
Es hat sich gezeigt, daß diese bekannten Isolierstege einer weiteren Verbesserung, insbesondere hinsichtlich der Wärmeisolierung zugänglich sind. Der Erfindung liegt daher die Aufgabe zugrunde, die Wärmeisolierung der Isolierstege bei einfacher Herstellbarkeit zu verbessern.It has been found that these known insulating bars are accessible for further improvement, in particular with regard to thermal insulation. The invention is therefore based on the object to improve the thermal insulation of the insulating bars with ease of manufacture.
Gelöst wird die Aufgabe durch einen Isoliersteg mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen der Erfindung finden sich in den Unteransprüchen.The object is achieved by an insulating web with the features of
Durch die Volumenvergrößerung des Isoliersteges mittels des zweiten Materials wird eine wesentliche Verringerung des Wärmeübergangs im Bereich des Isoliersteges bei einem Verbundprofil, insbesondere aus Aluminium, erreicht.Due to the increase in volume of the insulating web by means of the second material, a substantial reduction in the heat transfer in the region of the insulating web in a composite profile, in particular made of aluminum, is achieved.
Das volumenvergrößerte zweite Material des Isoliersteges ist dadurch hergestellt, daß der Trägerteil zusammen mit den Bereichen hoher Porosität durch Koextrusion hergestellt wird.The volume-enlarged second material of the insulating web is produced by the carrier part is produced together with the areas of high porosity by coextrusion.
Der Trägerteil kann aus polymerem Werkstoff, insbesondere Polyamid oder Polyäthylenterephtalat mit oder ohne Glasfaserteile bestehen, wodurch der erfindungsgemäße Isoliersteg die gleiche Steifigkeit wie diejenigen nach dem Stand der Technik aufweist.The support member may be made of polymeric material, in particular polyamide or polyethylene terephthalate with or without glass fiber parts, whereby the insulating web according to the invention has the same rigidity as those of the prior art.
Nach der Erfindung ist der Trägerteil durchgehend zwischen den beiden Enden des Steges ausgebildet, wobei er in Montagestellung des Isoliersteges zwischen den beiden Profilstücken des Verbundprofils, bevorzugt nach außen weist.According to the invention, the support member is formed continuously between the two ends of the web, wherein it points in the assembled position of the insulating web between the two profile pieces of the composite profile, preferably to the outside.
Als Material für die Bereiche hoher Porosität kommt insbesondere polymerer Werkstoff, wie bspw. modifiziertes PPO/PA Blend in Betracht.As a material for the areas of high porosity in particular polymeric material, such as, for example, modified PPO / PA blend comes into consideration.
Nach der Erfindung weist der Isoliersteg wenigstens einen Quersteg auf. Der Quersteg besteht ebenfalls aus hochporösem Material, und zwar aus dem gleichen Material wie das in der wannenförmigen Aufnahme befindliche zweite Material. Diese Maßnahme ist fertigungstechnisch besonders günstig, da das zweite Material des Isoliersteges und der Quersteg einstückig sind und damit in einem Arbeitsgang hergestellt werden können, was sich insbesondere in günstigen Werkzeug- und Herstellungskosten niederschlägt.According to the invention, the insulating web has at least one transverse web. The crossbar is also made of highly porous material, namely of the same material as the second material located in the trough-shaped receptacle. This measure is particularly favorable in terms of production, since the second material of the insulating web and the transverse web are integral and thus can be produced in one operation, which is reflected in particular in low tooling and manufacturing costs.
Durch gegenseitig sich überlappende Querstege können in bekannter Weise Innenkammern gebildet werden. Die Querstege können bzgl. ihrer gegenseitigen Anordnung aber auch in einem Abstand voneinander enden, entweder stirnseitig oder seitlich.By mutually overlapping transverse webs inner chambers can be formed in a known manner. With regard to their mutual arrangement, however, the transverse webs can also terminate at a distance from one another, either at the front or at the sides.
