Description

Die Erfindung betrifft ein wärmegedämmtes Verbundprofil gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a thermally insulated composite profile according to the preamble of claim 1.

Derartige Verbundprofile sind in zahllosen Ausführungsformen sowie in der EP 0 978 619 A2 vorbeschrieben und zum praktischen Einsatz gekommen. Gleichwohl bleibt nach wie vor das Problem, die thermischen Eigenschaften weiter zu verbessern. Hierzu ist es zwar grundsätzlich möglich, die Dicke der Einzeldämmleisten zu verringern; dem steht jedoch die damit verbundene geringere mechanische Festigkeit entgegen.Such composite profiles are in countless embodiments as well as in the EP 0 978 619 A2 described above and come to practical use. Nevertheless, the problem still remains of improving the thermal properties. For this it is possible in principle, the Reduce the thickness of the single insulation strips; However, this is contrary to the associated lower mechanical strength.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein wärmegedämmtes Verbundprofil der eingangs genannten Art unter dem Gesichtspunkt sowohl seiner thermischen als auch seiner mechanischen Eigenschaften zu optimieren.The invention is therefore based on the object to optimize a thermally insulated composite profile of the type mentioned above from the viewpoint of both its thermal and its mechanical properties.

Diese Aufgabe wird nach der Erfindung durch ein wärmegedämmtes Verbundprofil mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention by a thermally insulated composite profile with the features of claim 1.

Der durch die Erfindung erreichte Vorteil besteht im wesentlichen darin, daß durch die Verbindung von dünnwandigen Einzeldämmleisten mittels schräger bzw. gekrenzter Verbindungsstege gute mechanische Eigenschaften hinsichtlich Zugfestigkeit, Quersteifigkeit, Schubfestigkeit, Schubfedersteifigkeit und der Verbundkennwerte, gepaart mit sehr guten Dämmeigenschaften, erreicht werden.The advantage achieved by the invention consists essentially in the fact that good mechanical properties in terms of tensile strength, transverse rigidity, shear strength, shear stiffness and the composite parameters, coupled with very good insulation properties, are achieved by the connection of thin-walled Einzeldämmleisten by oblique or curved connecting webs.

Im Rahmen der Erfindung hat es sich dabei als vorteilhaft erwiesen, wenn die Wanddicke der Einzeldämmleisten im Bereich zwischen 0,5 und 1,5 mm liegt.In the context of the invention, it has proved to be advantageous if the wall thickness of the individual insulating strips in the range between 0.5 and 1.5 mm.

Als besonders günstig erscheint eine Ausgestaltung, bei der die Wanddicke der Einzeldämmleisten im Bereich zwischen 0,8 und 2,0 mm liegt.An embodiment in which the wall thickness of the individual insulating strips is in the range between 0.8 and 2.0 mm appears to be particularly favorable.

Entsprechend wird erfindungsgemäß vorgeschlagen, daß bei einem Aufbau mit zwei Verbindungsstegen deren Wanddicke im Bereich zwischen 1,0 und 1,5 mm liegt.Accordingly, the invention proposes that in a structure with two connecting webs whose wall thickness is in the range between 1.0 and 1.5 mm.

Auch hier ergibt sich eine besonders günstige Parameterkombination, wenn bei einem Aufbau mit zwei Verbindungsstegen deren Wanddicke im Bereich zwischen 1,0 und 2,0 mm liegt.Again, there is a particularly favorable parameter combination, if in a structure with two connecting webs whose wall thickness is in the range between 1.0 and 2.0 mm.

Aus thermischen wie auch aus mechanischen Gründen liegt erfindungsgemäß der Abstand zwischen dem Metallprofil und der Anschlußzone der Verbindungsstege an den Einzeldämmleisten im Bereich zwischen 20% und 40% der Gesamtbauhöhe der Einzeldämmleisten, wobei insbesondere der Bereich zwischen 25% und 35% der Gesamtbauhöhe bevorzugt wird.For thermal as well as mechanical reasons, the distance between the metal profile and the terminal zone of the connecting webs is according to the invention the individual insulating strips in the range between 20% and 40% of the total height of the individual insulating strips, in particular, the range between 25% and 35% of the total height is preferred.

Schließlich kann als weitere vorteilhafte Gestaltung vorgesehen sein, daß die Anschlußleisten über einen jeweils zur benachbarten Einzeldämmleiste weisenden Quersteg mit der Einzeldämmleiste verbunden sind.Finally, it can be provided as a further advantageous embodiment, that the terminal strips are connected via a respective facing the adjacent single dike bar with the Einzeldämmleiste.

Im folgenden wird die Erfindung an Hand eines in der Figur 3 dargestellten Ausführungsbeispieles näher erläutert; es zeigen:

  • Fig. 1 und 2 dem technologischen Hintergrund
  • Fig. 3 eine Ausführungsform der Erfindung in einer der Figur 1 entsprechenden Darstellung.
In the following the invention with reference to a in the FIG. 3 illustrated embodiment explained in more detail; show it:
  • Fig. 1 and 2 the technological background
  • Fig. 3 an embodiment of the invention in one of FIG. 1 corresponding representation.

Wärmegedämmte Verbundprofile für Fenster, Türen, Fassaden und ähnliche Anwendungen bestehen üblicherweise aus zwei vorzugsweise metallischen Profilen 1,2, die über Einzeldämmleisten 3 miteinander verbunden und im gegenseitigen Abstand gehalten sind. Die Profile 1,2 weisen hierzu meist schwalbenschwanzförmige Nuten auf, in die die Einzeldämmleisten 3 mit ihren jeweils als Anschlußleiste 4 ausgebildeten Längsrändern formschlüssig an den Profilen 1,2 angeschlossen sind.Thermally insulated composite profiles for windows, doors, facades and similar applications usually consist of two preferably metallic profiles 1, 2, which are connected to each other via single insulating strips 3 and held at a mutual distance. For this purpose, the profiles 1, 2 generally have dovetail-shaped grooves into which the individual insulating strips 3 with their longitudinal edges formed in each case as a terminal strip 4 are connected in a form-fitting manner to the profiles 1, 2.

Um bei derartigen Gestaltungen eine sowohl thermisch als auch mechanisch optimierte Verbindung zwischen den metallischen Profilen 1,2 zu schaffen, sind die beiden Einzeldämmleisten 3 gemäß Figur 1 über zwei Verbindungsstege 5 miteinander verbunden. Ebenso besteht die in Figur 2 dargestellte Möglichkeit, die Einzeldämmleisten 3 auch über drei oder gegebenenfalls mehr Verbindungsstege 5 miteinander zu verbinden. In den Figuren 1 und 2 sind die Verbindungsstege 5 als rechtwinklig zu den Einzeldämmleisten 3 ausgerichtete Querstege ausgebildet.In order to create a connection between the metallic profiles 1, 2 which is both thermally and mechanically optimized in such designs, the two individual insulating strips 3 are in accordance with FIG FIG. 1 connected via two connecting webs 5 with each other.

Entscheidend hierbei ist, daß die aufsummierte Gesamtdicke der Einzeldämmleisten 3 sowie aller Verbindungsstege 5 eine Mindestwanddicke von 1,6 mm nicht unterschreitet.The decisive factor here is that the cumulative total thickness of the single insulating strips 3 and all connecting webs 5 does not fall below a minimum wall thickness of 1.6 mm.

Um eine Optimierung hinsichtlich der thermischen und mechanischen Eigenschaften zu erreichen, sollte die Wanddicke der Einzeldämmleisten 3 im Bereich zwischen 0,5 und 1,5 mm, zweckmäßigerweise im Bereich zwischen 0,6 und 1 mm liegen.In order to achieve an optimization with regard to the thermal and mechanical properties, the wall thickness of the individual insulating strips 3 should be in the range between 0.5 and 1.5 mm, advantageously in the range between 0.6 and 1 mm.

Bei einem Aufbau mit zwei schrägen bzw. gekrenzten Verbindungsstegen 5, wie er aus der Figur 3 hervorgeht, sollte die Wanddicke der Verbindungsstege 5 im Bereich zwischen 0,8 und 2,0 mm, zweckmäßigerweise im Bereich zwischen 1 und 1,5 mmm liegen.In a structure with two oblique or curved connecting webs 5, as he from the FIG. 3 shows, the wall thickness of the connecting webs 5 should be in the range between 0.8 and 2.0 mm, suitably in the range between 1 and 1.5 mmm.

Der mit der Bezugsziffer 6 gekennzeichnete Abstand zwischen dem Metallprofil 1,2 und der Anschlußzone der Verbindungsstege 5 an den Einzeldämmleisten 3 liegt im Bereich zwischen 20 % und 40 % der mit der Bezugsziffer 7 bezeichneten Gesamtbauhöhe der Einzeldämmleisten 3 Bevorzugt ist hierbei insbesondere der Bereich zwischen 25% und 35% der Gesamtbauhöhe 7.The distance indicated by the reference numeral 6 between the metal profile 1,2 and the connection zone of the connecting webs 5 to the Einzeldämmleisten 3 is in the range between 20% and 40% of the total height designated by the reference numeral 7 of the single insulation strips 3 is preferred here in particular the range between 25 % and 35% of the total building height 7.

Wie sich im übrigen unmittelbar aus der Zeichnung ergibt, sind die Anschlußleisten 4 über einen jeweils zur benachbarten Einzeldämmleiste 5 weisenden Quersteg 8 mit der Einzeldämmleiste 3 verbunden.As can be seen, moreover, directly from the drawing, the terminal strips 4 are connected to the single-dowel strip 3 via a transverse web 8 pointing in each case to the adjacent single-dowel strip 5.

Die genannten Bemessungsvorschriften gelten insbesondere für eine Gesamtbauhöhe der Einzeldämmleisten 3 im Bereich zwischen 20 und 100 mm sowie bei einem gegenseitigen Abstand der Einzeldämmleisten 3 im Bereich zwischen 10 und 100 mm.The above design rules apply in particular to a total height of the individual insulating strips 3 in the range between 20 and 100 mm and at a mutual distance of the single insulating strips 3 in the range between 10 and 100 mm.
