Description

Die Erfindung betrifft eine Isolierglaseinheit und eine Tragkonstruktion mit mindestens einer derartigen Isolierglaseinheit.The invention relates to an insulating glass unit and a supporting structure with at least one such insulating glass unit.

Bei herkömmlichen Glaskonstruktionen sind die Isolierglaselemente in der Regel in einen Rahmen eingekittet oder sind unter direkter Anlage an entsprechenden Dichtungen zwischen den Dichtungen eingesetzt. Besonders bei dünneren Isolierglaselementen ergibt sich dabei das Problem, das die Dämmeigenschaften im Randbereich, d.h. im Verbindungsbereich der Isolierglaselemente mit entsprechenden Tragelementen, beeinträchtigt sind.In conventional glass structures, the insulating glass elements are usually cemented into a frame or are used under direct contact with corresponding seals between the seals. Especially with thinner insulating glass elements, this results in the problem that the insulating properties in the edge area, i. in the connecting region of the insulating glass elements with corresponding support elements, are impaired.

Aus der DE 195 16 486 A1 ist eine Isolierglaseinheit gemäß dem Oberbegriff des Anspruchs 1 mit einem Fensterprofil bekannt, bei dem eine Isolierglasscheibe an ihrem Rand von zwei miteinander verklebten Flügelprofilen eingefasst wird. Das eine Flügelprofil besteht vollständig aus Hartintegralschaum wohingegen das andere Flügelprofil nur im Randbereich aus einer Schale aus Hartintegralschaum besteht und die Schale innen mit Isolierschaum ausgefüllt ist.From the DE 195 16 486 A1 an insulating glass unit according to the preamble of claim 1 with a window profile is known in which an insulating glass pane is bordered at its edge by two glued together wing profiles. The one wing profile consists entirely of hard integral foam whereas the other wing profile consists only in the edge region of a shell made of hard integral foam and the shell is filled inside with insulating foam.

In der DE 10 2008 009 495 A1 ist eine Fensterkonstruktion offenbart, bei welcher der Fensterflügel aus zwei separaten Profilteilen, nämlich dem eigentlichen Flügelrahmen sowie einer daran nach dem Einsetzen einer Verglasung angesetzten Halteleiste, besteht. Die Verglasung wird hier in den Flügelrahmen eingesetzt und die Halteleiste wird an der äußersten Scheibe angesetzt und mit dem Flügelrahmen verklebt. Der Fensterflügel besteht vollständig aus geschäumtem Polyurethan.In the DE 10 2008 009 495 A1 discloses a window construction in which the sash consists of two separate profile parts, namely the actual sash and a thereto after the onset of glazing attached retaining strip exists. The glazing is used here in the casement and the retaining strip is attached to the outermost disc and glued to the casement. The sash is made entirely of foamed polyurethane.

Aufgabe der Erfindung ist es, eine Isolierglaseinheit und eine Tragkonstruktion mit mindestens einer derartigen Isolierglaseinheit zu schaffen, die auch bei dünneren Isolierglaselementen eine optimierte Wärmedämmung ennöglichen.The object of the invention is to provide an insulating glass unit and a supporting structure with at least one such insulating glass unit, which even with thinner insulating glass elements ennöglichen optimized thermal insulation.

Diese Aufgabe wird durch eine Isolierglaseinheit mit den Merkmalen des Anspruchs 1 und durch eine Tragkonstruktion mit den Merkmalen des Anspruchs 7 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.
Bei der erfindungsgemäßen Isolierglaseinheit ist an dem vorzugsweise als Vakuumisolierglaselement ausgebildeten ein Isolierglaselement ein spezielles Einfassprofil zur Montage der Isolierglaselemente an einer Tragkonstruktion angeordnet. Das Isolierglaselement und das Einfassprofil bilden eine Einheit, welche die Montage der Isolierglaseinheit an herkömmlichen Tragelementen vereinfacht und eine Verbesserung der Dämmeigenschaften ermöglicht. Das Einfassprofil besteht aus Kunststoff und weist einen weichen Kern und eine härtere Außenhaut auf. Das Einfassprofil besteht aus einem Zweikomponenten-Polyurethan mit einer harten äußeren Polyurethanhaut und einem weichen Polyurethankern. Während durch den weichen Polyurethankern eine besonders gute Dämmung erreichbar ist, sorgt die härtere Polyurethanhaut für die erforderliche Festigkeit und Stabilität. Der Polyurethankern besteht aus leichtem PU-Schaum mit einer Wärmeleitfähigkeit von λ = 0,02 bis 0,06 W/m2K, bevorzugt 0,025 W/m2K. Die harte Außenhaut besteht aus einer schwereren PU-Mischung mit einer Härte ähnlich von Hart-PVC und weist eine Wärmeleitfähigkeit von λ = 0,2 bis 0,6 W/m2K auf. Das Einfassprofil umschließt das Isolierglaselement an dessen Stirnseite und den Rändern seiner Front- und Rückseite und ist über ein Dichtprofil oder eine Dichtungsmasse fest mit dem Isolierglaselement verbunden. Dadurch sind ein besonders guter Schutz der Kanten des Isolierglaselements und eine gute Wärmedämmung erreichbar.
Zur Aufnahme von Dichtungen und/oder Dichtprofilen können an der Außenseite des Einfassprofils entsprechende Nuten und/oder Vertiefungen vorgesehen sein. In das Einfassprofil können auch zusätzliche Befestigungsprofile zur Befestigung der Isolierglaseinheiten an einem Tragelement eingelassen sein.
Das Isolierglaselement ist vorzugsweise als Vakuumisolierglaselement ausgeführt, bei dem sich in einem Scheibenzwischenraum zwischen zwei oder mehreren voneinander beabstandeten Scheiben ein Vakuum befindet. Derartige Vakuumisolierglaselemente weisen ausgezeichnete Dämmeigenschaften auf. Neben den Glaselementen können die Isolierglaseinheiten aber auch noch Thermopaneele oder andere zusätzliche Elemente aufweisen.This object is achieved by an insulating glass unit having the features of claim 1 and by a support structure having the features of claim 7. expedient Embodiments and advantageous developments of the invention are specified in the subclaims.
In the case of the insulating glass unit according to the invention, a special bordering profile for mounting the insulating glass elements to a supporting structure is arranged on the insulating glass element, preferably designed as a vacuum insulating glass element. The insulating glass element and the bordering profile form a unit which simplifies the installation of the insulating glass unit on conventional support elements and makes it possible to improve the insulating properties. The border profile is made of plastic and has a soft core and a harder outer skin. The border profile consists of a two-component polyurethane with a hard outer polyurethane skin and a soft polyurethane core. While a particularly good insulation is achievable thanks to the soft polyurethane core, the harder polyurethane skin provides the required strength and stability. The polyurethane core is made of lightweight PU foam with a thermal conductivity of λ = 0.02 to 0.06 W / m 2 K, preferably 0.025 W / m 2 K. The hard outer skin consists of a heavier PU mixture with a hardness similar to Hard PVC and has a thermal conductivity of λ = 0.2 to 0.6 W / m 2 K. The bordering profile surrounds the insulating glass element at its end face and the edges of its front and rear sides and is firmly connected to the insulating glass element via a sealing profile or a sealing compound. As a result, a particularly good protection of the edges of the insulating glass element and good thermal insulation can be achieved.
For receiving seals and / or sealing profiles corresponding grooves and / or depressions may be provided on the outside of the border profile. Additional fastening profiles for fastening the insulating glass units to a support element can also be embedded in the border profile.
The insulating glass element is preferably designed as a vacuum insulating glass element, in which there is a vacuum in a space between two or more spaced-apart panes. Such vacuum insulating glass elements have excellent insulating properties. In addition to the glass elements, the Insulating glass units but also have thermo panels or other additional elements.

Die Erfindung betrifft außerdem eine Tragkonstruktion, bei der eine oder mehrere der vorstehend erläuterten Isolierglaseinheiten an einem Tragelement befestigt sind. Bei den Tragelementen kann es sich z.B. um Profile für Pfosten oder Riegel einer Pfosten-Riegel-Konstruktion handeln, mit der Fassaden, Wintergärten, Glasdächer usw. herstellbar sind. Die Tragelemente können aber auch Profile einer Rahmenkonstruktion für Fenster, Türen oder dgl. sein. Die Isolierglaseinheit kann z.B. über das Einfassprofil mit Hilfe einer Pressleiste und Befestigungsschrauben oder mit Hilfe in das Einfassprofil eingelassener Befestigungsprofile an dem Tragelement befestigt sein. Die Isolierglaseinheit kann aber auch durch Ankleben des Einfassprofil am Tragelement befestigt werden oder kann zwischen einem Außenprofil und einem Innenprofil eines Rahmens, insbesondere eines Fenster- oder Türrahmens, angeordnet sein.The invention also relates to a support structure in which one or more of the above-described insulating glass units are fastened to a support element. The support elements may be e.g. to act profiles for posts or bars of a mullion-transom construction, with the facades, conservatories, glass roofs, etc. are produced. The support members may also be profiles of a frame construction for windows, doors or the like .. The insulating glass unit may e.g. be attached to the support member via the border profile using a pressure bar and mounting screws or with the help of embedded in the Einfassprofil fastening profiles. However, the insulating glass unit can also be attached by gluing the border profile on the support element or can be arranged between an outer profile and an inner profile of a frame, in particular a window or door frame.

In Figur 1 ist ein erstes Ausführungsbeispiel einer Isolierglaseinheit mit einem Isolierglaselement 1 und einem an Rand des Isolierglaselements 1 befestigten Einfassprofil 2 zur Montage der Isolierglaseinheit an einem in Figur 3 gezeigten Tragelement 3 dargestellt. Bei der gezeigten Ausführung ist das Isolierglaselement 1 als Vakuumisolierglaselement mit zwei über Abstandhalter 4 voneinander beabstandeten Glasscheiben 5 ausgeführt. Über ein Vakuum in einem zwischen den Glasscheiben 5 gebildeten Scheibenzwischenraum 6 wird ein gegenüber den üblichen Verglasungen verbesserter Wärmedurchgangskoeffizient erreicht. Durch die Abstandhalter 4 wird verhindert, dass die Glasscheiben 5 infolge des Vakuums im Scheibenzwischenraum 6 zusammengedrückt werden.In FIG. 1 is a first embodiment of an insulating glass unit with an insulating glass element 1 and attached to the edge of the insulating glass element 1 Einfassprofil 2 for mounting the insulating glass unit to a in FIG. 3 shown support element 3 shown. In the embodiment shown, the insulating glass element 1 is designed as Vakuumisolierglaselement with two spacers 4 spaced from each other glass sheets 5. Via a vacuum in a space between the panes 5 formed between the glass panes 5, a heat transfer coefficient which is improved compared with the conventional glazings is achieved. By the spacers 4 prevents the glass sheets 5 are compressed due to the vacuum in the space between the panes 6.

Das am Rand des Isolierglaselements 1 befestigte Einfassprofil 2 ist über eine Dichtmasse oder eine Profildichtung 7 abgedichtet fest mit dem Isolierglaselement 1 verbunden. Hierzu weist das Einfassprofil 2 eine rechteckige Aufnahmenut 8 zum Aufsetzen des Einfassprofils 2 auf den Rand des Isolierglaselements 1 auf. Das Einfassprofil 2 ist z.B. über einen geeigneten Klebstoff fest mit dem Isolierglaselement 1 verbunden und bildet damit nicht nur ein Montageelement für die Montage der Isolierglaseinheit, sondern stellt gleichzeitig einen Schutz gegen Beschädigungen der empfindlichen Scheibenkanten bei deren Transport oder bei der Montage dar. An der Außenseite des Einfassprofils sind Nuten 9 und Vertiefungen 10 für die Aufnahme von Dichtungen und Dichtungsprofilen vorgesehen.The attached to the edge of the insulating glass element 1 Einfassprofil 2 is sealed via a sealant or a gasket 7 firmly connected to the insulating glass element 1. For this purpose, the bordering profile 2 has a rectangular receiving groove 8 for placing the bordering profile 2 on the edge of the insulating glass element 1. The border profile 2 is e.g. firmly connected to the insulating glass element 1 via a suitable adhesive and thus not only forms a mounting element for mounting the insulating glass unit, but at the same time provides protection against damage to the sensitive wheel edges during their transport or assembly. The outside of the rail profile has grooves 9 and recesses 10 provided for receiving seals and sealing profiles.

Das Einfassprofil 2 ist aus Kunststoff mit einem weichen Kern 12 und einer härteren Außenhaut 11 hergestellt. Zweckmäßigerweise besteht das Einfassprofil aus einem Zweikomponenten-Polyurethan mit einem weicheren Kern 12 aus leichtem PU-Schaum und einer Wärmeleitfähigkeit von λ = 0,02 bis 0,06 W/m2K, bevorzugt 0,025 W/m2K. Die harte Außenhaut 11 besteht aus zweckmäßigerweise aus einer schwereren PU-Mischung mit einer Härte ähnlich von Hart - PVC und weist vorzugsweise eine Wärmeleitfähigkeit von λ = 0,2 bis 0,6 W/m2K auf. Durch den Kern 12, der aus leichtem PU-Schaum mit einer Wärmeleitfähigkeit von λ = 0,02 bis 0,06 W/m2K, bevorzugt 0,025 W/m2K, besteht, wird eine gute Dämmung erreicht. Die harte Außenhaut 11, die aus einer schwereren PU-Mischung mit einer Härte ähnlich von Hart PVC und einer Wärmeleitfähigkeit von λ = 0,2 bis 0,6 W/m2K besteht, sorgt dagegen für die erforderliche Festigkeit und Stabilität.The border profile 2 is made of plastic with a soft core 12 and a harder outer skin 11. Conveniently, the Einfassprofil consists of a two-component polyurethane with a softer core 12 made of lightweight PU foam and a thermal conductivity of λ = 0.02 to 0.06 W / m 2 K, preferably 0.025 W / m 2 K. The hard outer skin 11 Conveniently consists of a heavier PU mixture with a hardness similar to hard PVC and preferably has a thermal conductivity of λ = 0.2 up to 0.6 W / m 2 K on. By the core 12, which consists of lightweight PU foam with a thermal conductivity of λ = 0.02 to 0.06 W / m 2 K, preferably 0.025 W / m 2 K, a good insulation is achieved.
