Description

Die Erfindung betrifft ein wärmegedämmtes Verbundprofil für Fenster, Türen, Fassaden und dergleichen, mit wenigstens zwei vorzugsweise aus Metall bestehenden Profilen, die über mindestens einen zwischen den Profilen angeordneten und mit seinen als Anschlußleiste ausgebildeten Längsrändern an den Profilen angeschlossenen Dämmsteg miteinander verbunden und im Abstand voneinander gehalten sind.The invention relates to a thermally insulated composite profile for windows, doors, facades and the like, with at least two preferably made of metal profiles, which are connected via at least one arranged between the profiles and connected with its terminal strip formed as longitudinal edges of the profiles Dämmsteg together and at a distance from each other are held.

Derartige Verbundprofile sind in vielfältigen Ausführungsformen aus dem Stand der Technik bekannt und sorgen dafür, daß jedenfalls im Bereich des Verbundprofils selbst der Wärmeübergang zwischen den Profilen deutlich herabgesetzt ist. So beschreibt die DE 30 35 526 A1 einen Profilkörper für ein derartiges verbundprofil, der im übrigen bereits weitere Hohlkammern aufweist.Such composite profiles are known in various embodiments of the prior art and ensure that at least in the region of the composite profile itself, the heat transfer between the profiles is significantly reduced. That's how it describes DE 30 35 526 A1 one Profile body for such a composite profile, which in the rest already has more hollow chambers.

Aus der EP 1 255 019 A2 ist ein in solchen Verbundprofilen einsetzbarer Dämmsteg bekannt, der eine aus Seitenflächen gebildete Hohlkammer aufweist, wobei die Seitenflächen jeweils gelenkig miteinander verbunden sind und so eine Verformung der Hohlkammer erleichtern.From the EP 1 255 019 A2 is a usable in such composite profiles Dämmsteg known which has a hollow chamber formed from side surfaces, wherein the side surfaces are each hingedly connected to each other and thus facilitate deformation of the hollow chamber.

Im Falzbereich, wo bauartbedingt größere, vor allem in Wärmeleitungsrichtung tiefere Kammern gebildet werden, ist insbesondere durch Wärmekonvektion ein Wärmeübergang von dem einen zum anderen Profil zu beobachten, wodurch sich ein nicht tolerierbarer Wärmeverlust einstellt.In the rebate area, where design-related larger, especially in the direction of heat conduction deeper chambers are formed, a heat transfer from one to the other profile is observed in particular by heat convection, which sets a non-tolerable heat loss.

Der Erfindung liegt daher die Aufgabe zugrunde, im Anschlußbereich der Dämmstege eine zusätzliche Wärmedämmung zu erreichen, wobei zu beachten ist, daß zum Einrollen der Dämmstege in die an den Profilen vorgesehene Aufnahmenuten mittels sogenannter Verwalzrollen der Zugang zu jenen Zonen gleichwohl ungehindert möglich sein muß.The invention is therefore based on the object to achieve additional insulation in the connection area of the Dämmstege, it should be noted that for rolling the Dämmstege in the provided on the profiles grooves by means of so-called Verwalzrollen access to those zones must nevertheless be possible without hindrance.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß am Dämmsteg wenigstens eine Trägerleiste vorgesehen ist, an deren freiem Rand ein in Richtung zur jeweils benachbarten Anschlußleiste weisender Abdecksteg über ein elastisch ausgebildetes Scharnier verschwenkbar angeschlossen ist, wobei der Abdecksteg zusammen mit der Anschlussleiste, dem Dämmsteg, dem Profil und der Trägerleiste eine Hohlkammer bildet.This object is achieved according to the invention in that at least one support bar is provided on the insulating web, at the free edge of a facing towards each adjacent terminal strip Abdecksteg is pivotally connected via an elastically formed hinge, wherein the cover web together with the terminal block, the Dämmsteg , The profile and the carrier strip forms a hollow chamber.

Der durch die Erfindung erreichte vorteil besteht im wesentlichen darin, daß durch die mittels der Anschlußleiste sowie dem Abdecksteg gebildete Hohlkammer eine zusätzliche Verbesserung der Wärmedämmung im Anschlußbereich der Dämmstege erreicht wird, ohne daß hierdurch Erschwernisse oder Nachteile beim Einrollen der Dämmstege in die Aufnahmenuten der Profile auftreten. Das Verbundprofil kann daher bereits weitestgehend fertig vorkonfektioniert sein, so daß beim anschließenden Einrollen der Dämmstege keine nachteiligen Behinderungen auftreten können. Der Abdecksteg kann dabei in seiner Ruhelage an dem Profil in Anlage kommen oder diesem mit geringem Spalt gegenüberstehen.The advantage achieved by the invention consists essentially in the fact that an additional improvement of the thermal insulation in the connection region of the Dämmstege is achieved by the means of the terminal block and the cover web hollow, without this complications or disadvantages when rolling the Dämmstege occur in the grooves of the profiles , Therefore, the composite profile can already be ready prepackaged as far as possible, so that no adverse disabilities can occur during the subsequent rolling of Dämmstege. The cover bar can be in his Resting position on the profile come into contact or this face with a small gap.

In bevorzugter Ausführungsform der Erfindung ist das Scharnier derart ausgebildet, daß eine Verschwenkung des Abdeckstegs wahlweise in die eine und/oder die andere Richtung möglich ist. Dadurch besteht die Möglichkeit, mit den verwalzrollen entweder den Abdecksteg lediglich einzudrücken; der Abdecksteg kann dabei entweder derart vollständig verschwenkt werden, dass er die unmittelbare Anlage der Verwalzrollen an den Aufnahmenuten der Dämmstege erlaubt. Der Abdecksteg kann aber auch zur Anlage an den Aufnahmenuten gebracht werden, so dass die Verwalzrollen die Umformung mittelbar über den Abdecksteg vornehmen. Dies setzt eine ausreichende Härte und Widerstandsfertigkeit des Abdeckstegs voraus. Sofert es aus bestimmten Gründen erwünscht ist, besteht auch die Möglichkeit, den Abdecksteg in die entgegengesetzte Richtung, also vom Dämmsteg wegzuschwenken, wobei im Ergebnis nach Beendigung des Einrollvorgangs der Abdecksteg wieder in seine für die Wärmedämmung optimale Ausgangslage zurückkehrt.In a preferred embodiment of the invention, the hinge is designed such that a pivoting of the Abdeckstegs in either one and / or the other direction is possible. This makes it possible, with the rollers verwurzrollen either depress the Abdecksteg only; the cover web can either be pivoted so completely that it allows the direct investment of Verwalzrollen on the grooves of Dämmstege. The cover web can also be brought to bear against the receiving grooves, so that the Verwalzrollen make the transformation indirectly via the Abdecksteg. This requires sufficient hardness and resistance of the Abdeckstegs. If it is desired for certain reasons, it is also possible, the Abdecksteg wegzuschwenken in the opposite direction, ie away from the Dämmsteg, in the result after completion of the rolling-up of Abdecksteg returns to its optimum for thermal insulation starting position.

Für eine optimale Wärmedämmung ist es weiterhin von Vorteil, wenn am Dämmsteg zwei auf der gleichen Seite des Dämmstegs angeordnete Trägerleisten vorgesehen sind, die jeweils einen Abdecksteg tragen.For optimum thermal insulation, it is also advantageous if two webs arranged on the same side of the Dämmsteg are provided on the Dämmsteg, each carrying a Abdecksteg.

Die Trägerleiste ist zweckmäßigerweise im wesentlichen senkrecht zum Dämmsteg ausgerichtet, wobei der Abdecksteg im wesentlichen rechtwinklig an die Trägerleiste anschließt. Hierdurch werden in besonders einfacher Weise vorteilhaft konfigurierte Kammern gebildet, die für eine gute Wärmedämmung sorgen.The carrier strip is expediently oriented substantially perpendicular to the insulating web, wherein the cover web connects substantially at right angles to the carrier strip. As a result, advantageously configured chambers are formed in a particularly simple manner, which are suitable for a good thermal insulation.

Weiter hat es sich im Rahmen der Erfindung als vorteilhaft erwiesen, wenn die Breite des Abdeckstegs geringer ist als die Breite der Trägerleiste. Dadurch ist insbesondere ein Verschwenken des Abdeckstegs hin zum Dämmsteg möglich, ohne daß der eingeschwenkte Abdecksteg am Dämmsteg verklemmen kann.Furthermore, it has proven to be advantageous in the context of the invention if the width of the cover web is less than the width of the support strip. As a result, a pivoting of the cover web is possible in particular towards the Dämmsteg without the pivoted Abdecksteg can jam the Dämmsteg.

Vorteilhaft ist es hierbei weiter, wenn der Abdecksteg an einer am Profil vorstehenden Profilrippe oder an einer Profilwand anliegt und mit dieser eine geschlossene Hohlkammer formt.It is advantageous in this case further, when the cover web rests against a profiled rib projecting on the profile or on a profile wall and forms with this a closed hollow chamber.

Im Rahmen der Erfindung besteht insbesondere auch die Möglichkeit, daß der Abdecksteg im Querschnitt eine gewölbte, zum Profil hin weisende Form besitzt. Derartige abweichende Formgestaltungen ermöglichen eine optimale Anpassung der wärmedämmenden Maßnahmen an die örtlichen Verhältnisse im Falz.In the context of the invention, in particular, there is also the possibility that the cover web in cross-section has a curved shape pointing towards the profile. Such deviating form designs allow optimal adaptation of the heat-insulating measures to the local conditions in the fold.

Eine weitere, im Rahmen der Erfindung vorteilhafte Möglichkeit besteht darin, daß die Trägerleiste an ihrer zum Abdecksteg weisenden Seite mit einem Streifen aus vorzugsweise unter Erwärmung aufschäumendem Material belegt ist. Hierbei ist es weiter zweckmäßig, wenn der Abdecksteg in Anlage an dem aufschäumenden Material gehalten ist. In diesem Fall bedarf es keines Verschwenkens des Abdeckstegs beim Einrollen der Dämmstege, da dieser bereits durch den Kontakt mit dem aufschäumenden Material in der erforderlichen Stellung gehalten ist. Bei einem an den Einrollvorgang anschließenden Wärmeprozeß schäumt dann das Material auf, so daß nicht nur der Abdecksteg in seine vorgesehene Stellung überführt wird, sondern darüber hinaus der verbleibende Hohlraum mit dem aufgeschäumten Material ausgefüllt ist, was zu einer weiteren Verbesserung der Wärmedämmung führt.Another, advantageous in the context of the invention possibility is that the carrier strip is occupied on its side facing the cover web with a strip of preferably foaming under heating material. It is further expedient if the cover web is held in contact with the foaming material. In this case, there is no need to pivot the Abdeckstegs when rolling the Dämmstege, as this is already held by the contact with the foaming material in the required position. In a heat process subsequent to the curling process, the material then foams up, so that not only the cover web is transferred to its intended position, but also the remaining cavity is filled with the foamed material, which leads to a further improvement of the thermal insulation.

Darüber hinaus kann auch die von den beiden Trägerleisten gebildete Kammer, bevorzugt die Wand des Dämmstegs, mit aufschäumendem Material belegt sein. Somit wird auch dort eine Verringerung des freien und somit einer Konvektion unterliegenden Luftvolumens erreicht.In addition, the chamber formed by the two carrier strips, preferably the wall of the Dämmstegs be occupied with foaming material. Thus, there is also achieved a reduction in the free and thus convection subject air volume.

Zusätzlich oder alternativ kann die von den beiden Trägerleisten und dem Dämmsteg gebildete Kammer mit einer an den Trägerleisten angeschlossenen Deckleiste versehen sein.Additionally or alternatively, the chamber formed by the two carrier strips and the Dämmsteg be provided with a cover strip connected to the carrier strips.

Dies ist insbesondere beim Einsatz am Blendrahmen und im Türflügelfalz von Vorteil, da hierdurch die Anordnung so gewählt sein kann, daß die Deckleiste zusammen mit den Abdeckstegen einen bündigen Abschluß mit den Profilen bilden.This is particularly advantageous when used on the frame and the Türflügelfalz, as a result, the arrangement may be chosen so that the cover strip together with the Abdeckstegen form a flush termination with the profiles.

Sofern die Abdeckstege während des Einrollvorganges in eine von den Dämmstegen wegweisende Position aufgestellt werden sollen, empfiehlt es sich hierbei verfahrensmäßig, daß zum Einrollen der Dämmstege mittels Verwalzrollen ein Aufstellkeil vorgesehen ist, der vor den Verwalzrollen geführt ist und den Abdecksteg in eine vom Dämmsteg wegweisende Position aufstellt.If the Abdeckstege to be placed during the rolling in a groundbreaking position of the Dämmstegen position, it is advisable procedurally that for rolling up the Dämmstege means Verwalz rolls a Aufstellkeil is provided, which is guided in front of the Verwalzrollen and the Abdecksteg in a pioneering position from Dämmsteg sets up.

Das in der Zeichnung dargestellte wärmegedämmte Verbundprofil ist vorgesehen für den Bau von Fenstern, Türen, Fassaden und dergleichen. Es besteht aus zwei metallischen Profilen 1,2, die über Dämmstege 3 miteinander verbunden und im gegenseitigen Abstand voneinander gehalten sind.The thermally insulated composite profile shown in the drawing is intended for the construction of windows, doors, facades and the like. It consists of two metallic profiles 1,2, which are connected to each other via Dämmstege 3 and held at a mutual distance from each other.

Dazu sind die Dämmstege 3 an ihren Längsrändern mit Anschlußleisten 4 versehen, die in entsprechende Aufnahmenuten 5 an den Profilen 1,2 eingesetzt sind.For this purpose, the Dämmstege 3 are provided at their longitudinal edges with connecting strips 4, which are inserted into corresponding grooves 5 on the profiles 1.2.

Am Dämmsteg 3 sind in den dargestellten Ausführungsbeispielen jeweils zwei Trägerleisten 6 vorgesehen, an deren freiem Rand ein zur Anschlußleiste 4 weisender Abdecksteg 7 angeschlossen ist. Dieser Abdecksteg 7 ist durch ein elastisch ausgebildetes Scharnier 8 verschwenkbar, so daß beim Einrollen der Dämmstege 3 mittels Verwalzrollen 9 der Abdecksteg 7 vorübergehend weggeschwenkt werden kann, so daß die Profilleiste der die Anschlußleiste 4 aufnehmenden Aufnahmenut 5 frei für die Verwalzrolle 9 zugänglich ist. Hierdurch wird erreicht, daß die insbesondere bei großen Profiltiefen gebildete Hohlkammer im Falzbereich geschlossen oder zumindest verkleinert wird, so daß ein Wärmetransport durch über die Mitteldichtung zum Aluminiumprofil hin strömende kalte Luft verringert wird.At Dämmsteg 3 two support strips 6 are provided in the illustrated embodiments, at the free edge of a terminal strip 4 facing Abdecksteg 7 is connected. This cover web 7 is pivotable by an elastically formed hinge 8, so that when rolling the Dämmstege 3 by Verwalzrollen 9 Abdecksteg 7 can be temporarily pivoted away, so that the profile of the terminal block 4 receiving groove 5 is freely accessible for the Verwalzrolle 9. This ensures that the hollow chamber formed in particular in the case of large profile depths is closed or at least reduced in the folded area, so that a heat transfer is reduced by cold air flowing through the center seal towards the aluminum profile.

Zum Einrollen der Dämmstege 3 kann jedoch auch gemäß Fig. 7 vorgegangen werden, wonach der Abdecksteg 7 in Anlage an dem umzuformenden Steg der Aufnahmenut 5 für die Anschlussleiste 4 gebracht wird und dann die Umformung über den "zwischenliegenden" Abdecksteg 7 erfolgt.For rolling the Dämmstege 3 but also according to Fig. 7 be proceeded, after which the cover web 7 is brought into contact with the reshaped web of the receiving groove 5 for the terminal block 4 and then the transformation takes place via the "intermediate" Abdecksteg 7.

Das Scharnier 8 ist dabei derart ausgebildet, daß eine Verschwenkung des Abdeckstegs 7 wahlweise in die eine oder in die andere Richtung möglich ist, wie dies insbesondere in den Teilfiguren 1b) und 1c) dargestellt ist. Die Trägerleiste 6 und der Abdecksteg 7 können dabei aus gleichem oder auch unterschiedlichem Material koextrudiert sein; möglich ist auch eine Gestaltung, bei der wenigstens das Scharnier 8 materialmäßig weich eingestellt ist. Geeignet hierfür ist beispielsweise ein thermoplastisches Elastomer oder eine Kombination aus Gummi und Thermoplast. Vorteilhaft ist hierbei auch eine Materialverschlankung im Bereich des Scharniers 8.The hinge 8 is designed such that a pivoting of the Abdeckstegs 7 is optionally possible in one or the other direction, as shown in particular in the sub-figures 1b) and 1c). The carrier strip 6 and the Abdecksteg 7 can be coextruded from the same or different material; also possible is a design in which at least the hinge 8 is materially soft set. Suitable for this purpose is, for example, a thermoplastic elastomer or a combination of rubber and thermoplastic. A material slimming in the region of the hinge 8 is also advantageous here.

Die Trägerleiste 6 ist dabei im wesentlichen senkrecht zum Dämmsteg 3 ausgerichtet, während der Abdecksteg 7 wiederum im wesentlichen rechtwinklig an die Trägerleiste 6 anschließt.The support bar 6 is aligned substantially perpendicular to the Dämmsteg 3, while the cover web 7 in turn connects at right angles to the support bar 6 substantially.

Um insbesondere eine Verschwenkung des Abdeckstegs 7 in die in Figur 1b) dargestellte Richtung zu ermöglichen, ist die Breite des Abdeckstegs 7 geringer als die Breite der Trägerleiste 6.In particular, a pivoting of the Abdeckstegs 7 in the in FIG. 1b ), the width of the Abdeckstegs 7 is less than the width of the support bar. 6

Gemäß der in Figur 1a) dargestellten Ausgestaltung kann der Abdecksteg 7 an einer am Profil vorstehenden Profilrippe 10 anliegen und mit dieser eine geschlossene Hohlkammer formen. Dazu ist es je nach Ausgestaltung der Breite der Profilrippe 10 von Vorteil, wenn der Abdecksteg 7 im Querschnitt eine gewölbte, zum Profil 1,2 hin weisende Form besitzt.According to the in FIG. 1a ) illustrated embodiment, the Abdecksteg 7 abut a profiled rib on the profile 10 and form a closed hollow chamber with this. For this purpose, it is depending on the configuration of the width of the profile rib 10 is advantageous if the cover web 7 in cross-section has a curved, profile to 1.2 facing out form.

Zu einer weiteren Erhöhung der Wärmedämmung kann die Trägerleiste 6 an ihrer zum Abdecksteg 7 weisenden Seite mit einem Streifen aus vorzugsweise unter Erwärmung aufschäumendem Material 11 belegt sein, wie dies in den Figuren 2 und 5 dargestellt ist. Vor dem Einrollen der Dämmstege 3 nimmt hierbei das aufschäumende Material 11 einen derart geringen Raum ein, daß die Verwalzrollen 9 ohne weiteres die Profilleisten der Aufnahmenut 5 an die Anschlußleisten 4 andrücken können, während in einem nachfolgenden wärmeprozeß dann das Aufschäumen des Materials 11 erfolgt. Dabei besteht insbesondere auch die Möglichkeit, daß der Abdecksteg 7 in Anlage an dem aufzuschäumenden Material 11 gehalten ist, so daß der Abdecksteg 7 von Anfang an in seiner den Zugang der Verwalzrolle 9 ermöglichenden Stellung gehalten ist.To a further increase in thermal insulation, the support bar 6 may be occupied on its side facing the cover web 7 with a strip of preferably foaming under heating material 11, as shown in the Figures 2 and 5 is shown. Before curling the Dämmstege 3 takes in this case the foaming material 11 such a small space that the Verwalzrollen 9 can easily press the profile strips of the receiving groove 5 to the terminal strips 4, while in a subsequent heat process then the foaming of the material 11 takes place. In particular, there is the possibility that the cover web 7 is held in abutment against the material to be foamed 11, so that the cover web 7 is held from the beginning in its access the Verwalzrolle 9 enabling position.

Darüber hinaus ist es auch möglich, die von den beiden Trägerleisten 6 gebildete Kammer 12, hierbei bevorzugt die Wand des Dämmstegs 3 mit aufschäumendem Material 11 zu belegen, wie dies aus den Figuren 2b) und 5b) zu ersehen ist. Gemäß dem Ausführungsbeispiel nach Figur 5 kann hierbei die von den beiden Trägerleisten 6 und dem Dämmsteg 3 gebildete Kammer 12 auch mit einer an den Trägerleisten 6 angeschlossenen Deckleiste 13 versehen sein.In addition, it is also possible for the chamber 12 formed by the two carrier strips 6, in this case preferably to occupy the wall of the Dämmstegs 3 with foaming material 11, as can be seen from the FIGS. 2b ) and 5b ) is to be seen. According to the embodiment according to FIG. 5 In this case, the chamber 12 formed by the two carrier strips 6 and the insulating web 3 may also be provided with a cover strip 13 connected to the carrier strips 6.

Das Ausführungsbeispiel nach Figur 3 zeigt einen Blendrahmen sowie einen Türflügelfalz, bei welchem die Deckleiste 13 zusammen mit den Abdeckstegen 7 einen bündigen Abschluß mit den Profilen 1,2 bildet. Auf diese Weise wird speziell bei Haustüren aus Aluminium-Verbundprofilen das Erscheinungsbild des Falzes optisch verbessert. Darüberhinaus erfolgt dort hinter den Abdeckstegen 7 keine Beschichtung mit Farbe, da der Farbauftrag üblicherweise erst nach der Montage der Dämmstege 3 vorgenommen wird. Dies hat den Vorteil eines geringeren Strahlungsübergangs im nicht beschichteten Bereich.The embodiment according to FIG. 3 shows a frame and a Türflügelfalz in which the cover strip 13 forms a flush termination with the profiles 1,2 together with the Abdeckstegen 7. In this way, the appearance of the rebate is visually improved, especially in front doors made of aluminum composite profiles. Moreover, there is behind the Abdeckstegen 7 no coating with color, since the paint is usually made only after installation of the Dämmstege 3. This has the advantage of less radiation transfer in the uncoated area.

In Figur 6 ist der Vorgang des Einrollens der Dämmstege 3 in perspektivischer Darstellung wiedergegeben, wobei dort den Verwalzrollen 9 ein Aufstellkeil 14 vorausläuft, der jedenfalls dann notwendig ist, wenn der Abdecksteg 7 nicht zum Dämmsteg 3 hin verschwenkt werden soll, sondern in eine vom Dämmsteg 3 abweisende Position aufgestellt werden soll. Dies ist insbesondere aus den Figuren 6b) und 6c) gut erkennbar.In FIG. 6 is the process of curling the Dämmstege 3 reproduced in a perspective view, where the Verwalzrollen 9 precedes a Aufstellkeil 14, which is certainly necessary if the Abdecksteg 7 is not to be pivoted to the Dämmsteg 3, but in a repellent from the dam 3 position should be set up. This is especially true of the FIGS. 6b) and 6c ) good to see.
