Description

Die Erfindung betrifft ein wärmegedämmtes Verbundprofil für Rahmen von Fenstern, Türen, Fassadenelementen oder dergleichen, mit innen- und außenseitigen Rahmenprofilen aus Metall sowie wenigstens einem die Rahmenprofile miteinander verbindenden Dämmsteg, der dazu randseitig mit Anschlußleisten zur Verbindung mit Rahmenprofilen versehen ist.The invention relates to a thermally insulated composite profile for frames of windows, doors, facade elements or the like, with inside and outside frame profiles made of metal and at least one frame profiles interconnecting Dämmsteg which is provided at the edge with terminal strips for connection to frame profiles.

Derartige Verbundprofile sind in vielfältigen Ausführungsformen vorbeschrieben sowie aus der Praxis bekannt. Grundsätzlich besteht bei derartigen Verbundprofilen das Problem, die Wärmeübertragung über den Dämmsteg so gering wie möglich zu halten, was in erster Näherung durch eine Verringerung der Wandstärke zu erreichen ist. Dem steht jedoch die damit einhergehende Verringerung der statischen Festigkeit entgegen, so daß üblicherweise ein Kompromiss hinsichtlich Wärmedämmung einerseits und Statik andererseits eingegangen werden muss.Such composite profiles are described in various embodiments and known from practice. Basically, in such composite profiles there is the problem of keeping the heat transfer via the Dämmsteg as low as possible, which can be achieved in a first approximation by reducing the wall thickness. However, this is the associated Reduction of the static strength, so that usually a compromise in terms of thermal insulation on the one hand and static on the other hand must be addressed.

Aufgabe der Erfindung ist es, eine Möglichkeit aufzuzeigen, durch die eine Verbesserung der Wärmedämmung erreicht wird, ohne gleichzeitig die statische Festigkeit des Verbundprofiles zu verringern.The object of the invention is to show a way by which an improvement of the thermal insulation is achieved without simultaneously reducing the static strength of the composite profile.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß ein Dämmsteg mit schalenförmigen Ausformungen in Gestalt von Erhebungen und/oder Vertiefungen im Bereich zwischen den Anschlußleisten vorgesehen ist.This object is achieved according to the invention in that a Dämmsteg is provided with cup-shaped formations in the form of elevations and / or depressions in the area between the terminal strips.

Der durch die Erfindung erreichte Vorteil besteht zunächst darin, daß durch die die Erhebungen bzw. die Vertiefungen umgebenden Anlaufflanken eine Vergrößerung des Wegs für die Wärmeleitung erreicht wird, ohne daß sich hierdurch die tatsächliche Breite des Dämmstegs, also der Abstand der Anschlußleisten sich ändert. Somit wird bereits durch diese Maßnahme eine Verringerung der Wärmeleitung erreicht. Hinzu kommt jedoch, daß die Erhebungen bzw. Vertiefungen im Zusammenwirken mit den Anlaufflanken zu einer Versteifung des Dämmsteges führen indem sie im weitesten Sinne Rippen bilden, die dem Dämmsteg eine erhöhte Festigkeit verleihen. Somit kann durch diese Ausbildung des Dämmstegs - ohne Änderungen am Verbundprofil im Übrigen - sowohl eine Verringerung der Wärmeleitfähigkeit als auch eine erhöhte Festigkeit erreicht werden.The advantage achieved by the invention consists first in that an enlargement of the path for the heat conduction is achieved by the elevations or the depressions surrounding, without thereby changing the actual width of the Dämmstegs, so the distance between the terminal strips. Thus, a reduction of the heat conduction is already achieved by this measure. In addition, however, that the elevations or depressions in cooperation with the leading edges lead to a stiffening of the Dämmsteges by forming ribs in the broadest sense, which give the Dämmsteg increased strength. Thus can be achieved by this design of the Dämmstegs - without changes to the composite profile in the rest - both a reduction in thermal conductivity and increased strength.

Darüber hinaus hilft die erfindungsgemäße Lösung, sowohl die Wärmestrahlungsverluste wegen der größeren Abschattungsflächen als auch die Wärmekonvektionsverluste, bedingt durch die strukturierten Flächen der Kammerwände, etwas zu mindern.In addition, the solution according to the invention helps to somewhat reduce both the heat radiation losses due to the larger shading areas and the heat convection losses due to the structured surfaces of the chamber walls.

Nach einer ersten vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, daß die Erhebungen bzw. Vertiefungen sich, quer zur Dämmsteglängsrichtung, nahezu über die gesamte, zwischen den Anschlußleisten liegende Breite erstrecken.According to a first advantageous embodiment of the invention can be provided that the elevations or depressions, transverse to Dämmsteglängsrichtung, almost over the entire, lying between the terminal strips width.

Grundsätzlich können sowohl der Abstand zwischen den Erhebungen und den Vertiefungen in der Längsrichtung, als auch ihre Höhen bzw. Tiefen frei gewählt werden. Eine optimale Wirkung wird jedoch dann erreicht, wenn die Erhebungen bzw. Vertiefungen unmittelbar aufeinander folgen.In principle, both the distance between the elevations and the depressions in the longitudinal direction, as well as their heights or depths can be freely selected. However, an optimal effect is achieved when the elevations or depressions follow each other directly.

Eine besonders gute Wirkung wird im Rahmen der Erfindung dann erreicht, wenn die Erhebungen bzw. Vertiefungen plateauförmig gestaltet sind, wobei die Erhebungen etwa den gleichen Flächenanteil wie die Vertiefungen aufweisen Dabei ist es generell von Vorteil, wenn die Erhebungen bzw. die Vertiefungen in Dämmsteglängsrichtung äquidistant angeordnet sind.A particularly good effect is achieved in the invention when the elevations or depressions are designed plateau-shaped, wherein the elevations have approximately the same area ratio as the wells It is generally advantageous if the elevations or depressions in Dämmsteglängsrichtung equidistant are arranged.

Eine besonders einfache und daher im Rahmen der Erfindung bevorzugte Ausgestaltung sieht vor, daß die Erhebungen bzw. Vertiefungen so angeordnet sind, daß entweder die Vertiefungen oder die Erhebungen auf der Basisebene des Dämmstegs sich befinden.A particularly simple and therefore preferred embodiment of the invention provides that the elevations or depressions are arranged so that either the wells or the elevations are located on the base plane of the Dämmstegs.

Desweiteren können die Erhebungen einerseits und die Vertiefungen andererseits unterschiedliche Flächenanteile aufweisen; auch hier ist von Vorteil, wenn die Erhebungen bzw. die Vertiefungen in Dämmsteglängsrichtung äquidistant angeordnet sind.Furthermore, the elevations on the one hand and the depressions on the other hand may have different area proportions; Here too, it is advantageous if the elevations or the depressions are arranged equidistantly in the insulating web longitudinal direction.

Eine weitere Ausgestaltung sieht vor, daß die Erhebungen bzw. Vertiefungen wellenförmig in der Art eines Sinus oder zick-zack-artig ausgebildet sind, wobei auch hier die den Anschlußleisten zugewandten Seiten mit entsprechend geformten Anlaufflanken versehen sind.A further embodiment provides that the elevations or depressions are wave-shaped in the manner of a sine or zig-zag-like, with here the terminal strips facing sides are provided with correspondingly shaped start flanks.

Neben diesen sehr regelmäßigen Gestaltungen der Erhebungen bzw. Vertiefungen besteht jedoch auch die Möglichkeit, hier je nach Anwendungszweck deutlich abweichende Gestaltungen vorzusehen. So können die Erhebungen bzw. Vertiefungen beispielsweise von linsen- oder pyramidenförmigen Ausformungen gebildet sein.In addition to these very regular designs of the surveys or depressions, however, it is also possible to provide significantly different designs depending on the intended use. Thus, the elevations or depressions may be formed for example by lens or pyramidal formations.

Eine weitere derartige Möglichkeit ist dadurch gekennzeichnet, daß die Erhebungen bzw. Vertiefungen von jeweils mehreren, in Längsrichtung des Dämmstegs nebeneinander angeordneten konzentrischen Kreisen gebildet sind.Another such possibility is characterized in that the elevations or depressions are each formed of a plurality of concentric circles arranged side by side in the longitudinal direction of the Dämmstegs.

Es ist ebenso auch möglich, daß die Erhebungen bzw. Vertiefungen von dreieckförmigen, sich paarweise parallelogrammartig ergänzenden Ausformungen gebildet sind.It is also possible that the elevations or depressions of triangular, in pairs parallelogram-like complementary formations are formed.

Schließlich besteht die Möglichkeit, daß die Erhebungen bzw. Vertiefungen aus Buchstaben, Ziffern oder vergleichbaren Symbolen gebildeten Ausformungen bestehen. Hierdurch können die Dämmstege beispielsweise mit Herstellernamen, mit Material- bzw. Verarbeitungshinweisen oder ähnlichen technischen Informationen versehen sein.Finally, there is the possibility that the elevations or depressions consist of letters, numbers or similar symbols formed formations. As a result, the Dämmstege can be provided, for example, with manufacturer names, with material or processing instructions or similar technical information.

Sofern das Verbundprofil wenigstens zwei die Rahmenprofile miteinander verbindende'Dämmstege aufweist, besteht weiter die Möglichkeit, daß die Dämmstege im wesentlichen parallel zueinander und mit gegenseitigem Abstand angeordnet sind, wobei der zwischen den Dämmstegen gebildete Spalt mit Isoliermaterial gefüllt ist. Hierdurch kann nicht nur eine verbesserte Wärmedämmung, sondern auch eine erhöhte Festigkeit erreicht werden.If the composite profile has at least two insulating webs connecting the frame profiles, there is also the possibility that the insulating webs are arranged essentially parallel to one another and at a mutual distance, wherein the gap formed between the insulating webs is filled with insulating material. As a result, not only improved thermal insulation, but also increased strength can be achieved.

Um dies zu erreichen, kann das Isoliermaterial von einem Schaumkörper gebildet sein, der an den Erhebungen und/oder Vertiefungen verklebt ist. Alternativ besteht auch die Möglichkeit, daß das Isoliermaterial von einem "naß" eingespritzten Schaum gebildet ist.To achieve this, the insulating material may be formed by a foam body, which is glued to the elevations and / or depressions. Alternatively, there is also the possibility that the insulating material is formed by a "wet" injected foam.

Schließlich kann hierbei auch vorgesehen sein, daß die Dämmstege gemeinsam mit dem Isoliermaterial als Sandwich-Aufbau vorgefertigt sind.Finally, it can also be provided that the Dämmstege are prefabricated together with the insulating material as a sandwich structure.

Im Folgenden wird die Erfindung an in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert; es zeigen:

In Fig. 1 ist in nur teilweiser Darstellung ein Fenster-Flügelrahmen 1 einschließlich des Blendrahmens 2 in einer Schnittdarstellung wiedergegeben. Beide Rahmen 1,2 bestehen jeweils aus innen- und außenseitigen Rahmenprofilen aus Metall, die über Dämmstege 3 miteinander verbunden sind. Dazu sind die Dämmstege 3 randseitig mit Anschlußleisten 4 versehen, die in entsprechenden Aufnahmen der Rahmenprofile gehalten sind.In Fig. 1 is shown in only partial representation, a window sash 1 including the frame 2 in a sectional view. Both frames 1.2 consist of inner and outer frame profiles made of metal, which are connected to each other via Dämmstege 3. For this purpose, the Dämmstege 3 edge provided with terminal strips 4, which are held in corresponding receptacles of the frame profiles.

Um die über diese Dämmstege 3 stattfindende Wärmeleitung zu verringern, wird üblicherweise die Dicke dieser Dämmstege 3 so dünn wie möglich gewählt, wobei hier die geforderte statische Festigkeit Grenzen setzt.In order to reduce the heat conduction taking place via this insulating webs 3, the thickness of these insulating webs 3 is usually chosen to be as thin as possible, with the required static strength setting limits here.

Eine Verringerung des Wärmeflusses wird jedoch auch durch eine Vergrößerung der Weglänge durch die Anlaufflanken 8 erreicht, weswegen der Dämmsteg 3 im Bereich zwischen den Anschlußleisten 4 mit Erhebungen 5 und/oder Vertiefungen 6 versehen wird, wie dies aus den Fig. 2 bis 8 zu ersehen ist. Da diese Erhebungen 5 bzw. Vertiefungen 6 im Zusammenwirken mit den Anlaufflanken 8 auch zu einer Versteifung des Dämmstegs 3 führen, besteht durch diese Maßnahme darüber hinaus die Möglichkeit, die Materialstärke deutlich zu verringern, wodurch der Wärmefluß zusätzlich gemindert wird.However, a reduction of the heat flow is achieved by increasing the path length through the start flanks 8, which is why the Dämmsteg 3 is provided in the area between the terminal strips 4 with elevations 5 and / or depressions 6, as shown in Fig. 2 to 8 can be seen. Since these surveys 5 or depressions 6 in cooperation with the start flanks 8 also lead to a stiffening of the dam web 3, this measure moreover makes it possible to significantly reduce the material thickness, as a result of which the heat flow is additionally reduced.

Neben der vorangehend beschriebenen Verringerung des Wärmefluß durch das Material, bewirken die Anlaufflanken 8 eine zusätzliche Abschattung gegen Strahlungsverluste. Zudem wird an den strukturierten Begrenzungsflächen der Dämmstegkammer die Luft beim Zirkulieren etwas gehindert, wodurch die Konvektionsverluste gemindert werden.In addition to the above-described reduction of the heat flow through the material, the start flanks 8 cause additional shading against radiation losses. In addition, the air circulating on the structured boundary surfaces of the Dämmstegkammer is somewhat prevented, whereby the Konvektionsverluste be reduced.

Wie sich beispielsweise aus den Fig. 2 bis 4 ergibt, erstrecken sich die Erhebungen 5 bzw. die Vertiefungen 6 über nahezu die gesamte, zwischen den Anschlußleisten 4 liegende Breite des Dämmstegs 3. Dabei können die Erhebungen 5 bzw. die Vertiefungen 6 gemäß Fig. 2 unmittelbar aneinander anschließen. Zudem sind die Erhebungen 5 und die Vertiefungen 6 hier äquidistant angeordnet und haben etwa gleiche Flächenanteile, während dies in Fig. 4 nicht der Fall ist.How, for example, from the Fig. 2 to 4 shows the elevations 5 and the recesses 6 extend over almost the entire, lying between the terminal strips 4 width of the Dämmstegs 3. In this case, the elevations 5 and the recesses 6 according to Fig. 2 connect directly to each other. In addition, the elevations 5 and the recesses 6 are arranged equidistantly here and have approximately the same area proportions, while in Fig. 4 not the case.

In Fig. 5 ist ein Ausführungsbeispiel gezeigt, bei welchem die Erhebungen 5 bzw. Vertiefungen 6 wellenförmig in der Art eines Sinus oder zick-zack-artig ausgebildet sind.In Fig. 5 an embodiment is shown in which the elevations 5 and depressions 6 are wave-shaped in the manner of a sine or zig-zag-like.

Bei der Ausführungsform gemäß Fig. 6 sind die Erhebungen 5 bzw. Vertiefungen 6 von linsen- oder pyramidenförmigen Ausformungen gebildet.In the embodiment according to Fig. 6 the elevations 5 and depressions 6 are formed by lenticular or pyramidal formations.

Eine weitere Möglichkeit ist in Fig. 7 gezeigt; hier sind im linken Teil die Erhebungen 5 bzw. die Vertiefungen 6 von jeweils mehreren, in Längsrichtung des Dämmstegs 3 nebeneinander angeordneten konzentrischen Kreisen gebildet, während in der rechten Hälfte dreieckförmige, sich paarweise parallelogrammartig ergänzende Ausformungen vorgesehen sind.Another option is in Fig. 7 shown; Here, in the left part of the elevations 5 and the recesses 6 are each formed of a plurality of concentric circles arranged side by side in the longitudinal direction of the Dämmstegs 3, while in the right half triangular, in pairs parallelogram complementary formations are provided.

Im Übrigen besteht auch noch die in der Zeichnung nicht näher dargestellte Möglichkeit, daß die Erhebungen 5 bzw. Vertiefungen 6 aus Buchstaben, Ziffern oder vergleichbaren Symbolen gebildeten Ausformungen bestehen. Hierdurch wird zusätzlich die Möglichkeit geschaffen, den Dämmsteg 3 mit Herkunftsangaben, herstellerspezifischen Informationen oder ähnlichen Angaben zu versehen, die bei der Verarbeitung der Dämmstege 3 relevant bzw. hilfreich sein können.Moreover, there is also the possibility, not shown in detail in the drawing, that the elevations 5 or depressions 6 are made of letters, numbers or comparable Symbols formed educations exist. This additionally provides the possibility to provide the Dämmsteg 3 with indications of origin, manufacturer-specific information or similar information that may be relevant or helpful in the processing of Dämmstege 3.

In den Fig. 8 bis 10 ist eine aus zwei die Rahmenprofile miteinander verbindenden Dämmstege 3 bestehende Ausführungsform gezeigt, bei welcher die beiden Dämmstege 3 parallel zueinander mit gegenseitigem Abstand angeordnet sind. Hierbei ist der zwischen den Dämmstegen gebildete Spalt mit Isoliermaterial 7 gefüllt.In the Fig. 8 to 10 is a two of the frame profiles interconnecting Dämmstege 3 existing embodiment shown in which the two Dämmstege 3 are arranged parallel to each other at a mutual distance. Here, the gap formed between the Dämmstegen is filled with insulating material 7.

Dabei kann das Isoliermaterial 7 von einem Schaumkörper gebildet sein, der an den Erhebungen 5 und/oder den Vertiefungen 6 verklebt ist, wie dies in Fig. 9 angedeutet ist.In this case, the insulating material 7 may be formed by a foam body which is glued to the elevations 5 and / or the depressions 6, as shown in FIG Fig. 9 is indicated.

Alternativ kann das Isoliermaterial 7 jedoch von einem "naß" eingespritztem Isolierschaum gebildet sein, wobei dann - wie in Fig. 10 angedeutet - auch die Möglichkeit besteht, daß die Dämmstege 3 gemeinsam mit dem Isoliermaterial 7 als Sandwich-Aufbau vorgefertigt sind.Alternatively, however, the insulating material 7 may be formed by a "wet" injected insulating foam, in which case - as in Fig. 10 indicated - the possibility exists that the Dämmstege 3 are prefabricated together with the insulating material 7 as a sandwich structure.
