Abstract

The unit has two glasses (200, 210) arranged at a distance to each other. The glasses are gas tightly connected in side regions by using a spacer-frame made up of profile rods. One of the rods is a solid profile rod, and a boundary gap is formed between the glasses in the regions. The gap has cross section in trapezoid form, and contour of the solid rod is arranged in the side regions and corresponds to the contour of the gap. An independent claim is also included for a facade with an insulating glass unit.

Description

Die Erfindung bezieht sich auf ein lsolier-Scheibenelement mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to an insulating disk element with the features of the preamble of patent claim 1.

Aus dem deutschen Gebrauchsmuster DE-GM 94 11 674 ist ein Element für eine Fassadenverkleidung bekannt, das aus zwei oder mehreren, parallel liegenden Glasscheiben besteht. Die Glasscheiben sind mit einem am äußeren Randbereich durchgehend angebrachten Abstandsmittel so miteinander verbunden, dass zwischen den Scheiben und dem Abstandsmittel ein luftdichter Raum entsteht. Die Abstandsmittel bestehen aus Glasstreifen, die mittels einer durchsichtigen Kleberschicht beidseitig mit den Glasscheiben fest verbunden sind. Durch die Verwendung von Materialien mit gleichen Ausdehnungskoeffizienten für die Scheiben und das Abstandsmittel, können große Scheibenabmessungen verwendet werden, ohne dass schädliche Spannungen entstehen.From the German utility model DE-GM 94 11 674 an element for a facade cladding is known, which consists of two or more, parallel glass panes. The glass sheets are connected to one another at the outer edge region continuously attached spacer means such that between the disks and the spacer means an air-tight space is formed. The spacers consist of glass strips, which are firmly connected on both sides by means of a transparent adhesive layer with the glass sheets. By using materials with equal coefficients of expansion for the disks and the spacer, large disk dimensions can be used without creating harmful stresses.

Das DE-GM 73 32 192 offenbart eine Isolierglasscheibe mit einer nach außen gewölbten Außenscheibe. Die Isolierglasscheibe besteht aus zwei im Abstand voneinander angeordneten im Randbereich mittels eines Abstandshalterrahmens miteinander verbundenen Einzelscheiben. Durch die Wölbung soll die Isolationswirkung verbessert und/oder die Durchsicht verringert werden. Die Einzelscheiben sind so gewölbt, dass deren Randbereiche im Wesentlichen parallel zu einander beabstandet sind, sie also etwa kuppelförmig gebogen sind. Der Abstandsrahmen weist eine den Scheibenrändern zugewandte Kunststoffschicht auf, die der verbleibenden, aufgrund der unterschiedlichen Endtangenten vorhandenen Randwölbung angepasst ist.DE-GM 73 32 192 discloses an insulating glass pane with an outwardly curved outer pane. The insulating glass consists of two spaced-apart in the edge region by means of a spacer frame interconnected individual discs. The curvature is intended to improve the insulating effect and / or to reduce the transparency. The individual disks are curved so that their edge regions are substantially parallel to each other, so they are bent approximately dome-shaped. The spacer frame has a plastic layer facing the disk edges, which is adapted to the remaining edge curvature present due to the different end tangents.

Das deutsche Gebrauchsmuster DE 203 04 806 U1 offenbart eine radarreflexionsdämpfende Doppelverglasung, die insbesondere für Gebäude vorgesehen ist. Die Doppelverglasung weist eine Außenscheibe mit einer Radarstrahlen teilweise reflektierenden Schicht dünner, zueinander parallel angeordneter Leiter und eine mit einer radarreflektierenden Schicht versehene Innenscheibe auf. Die Außen- und die Innenscheibe schließen nach Art einer Isolierglasscheibe einen luftdicht abgeschlossenen Zwischenraum zwischen sich ein. Die Anordnung der Leiter an der Außenscheibe und deren Abstand zu der radarreflektierenden Schicht auf der Innenscheibe ist in Abhängigkeit der Polarisationsrichtung der Radarstrahlen so gewählt, dass die jeweils reflektierten Anteile der Radarstrahlen einander gegenphasig überlagert und die einfallenden Radarstrahlen dadurch ausgelöscht werden. Als teilreflektierende Schicht dient ein Muster von Streifen einer elektrisch gut leitfähigen Silberpaste, die auf eine Oberfläche der Außenscheibe aufgedruckt und teilweise eingebrannt ist, wobei die Breite der aufgedruckten Streifen größer als deren Schichtdicke ist. Die Doppelverglasung kann auch eine Krümmung zur Außenseite hin aufweisen.The German Utility Model DE 203 04 806 U1 discloses a radar reflection-damping double glazing, which is particularly intended for buildings. The double glazing has an outer pane with a radar-beam partially reflecting layer of thin conductors arranged parallel to one another and an inner pane provided with a radar-reflecting layer. The outer and the inner pane close in the manner of an insulating glass a hermetically sealed space between them. The arrangement of the conductors on the outer pane and their distance from the radar reflecting layer on the inner pane is dependent on the polarization direction the radar beams chosen so that the respective reflected portions of the radar beams superimposed on each other in phase and the incident radar beams are extinguished thereby. As a partially reflecting layer is a pattern of strips of electrically good conductive silver paste, which is printed on a surface of the outer pane and partially baked, wherein the width of the printed strip is greater than the layer thickness. The double glazing may also have a curvature towards the outside.

Die aus dem Stand der Technik bekannten Isolierglasscheiben und Isolier-Fassadenelemente weisen im Wesentlichen parallel zueinander angeordnete Scheiben auf. Mit solchen Isolier-Elementen können entweder nur ebene Flächen oder geringe Flächenkrümmungen hergestellt werden, oder es muss mit relativ kleinflächigen Einzelelementen eine stark gekrümmte Fläche nachgebildet werden. In einigen Fällen kann es auch erwünscht sein, mit der äußeren Oberfläche der Isolierelemente den Verlauf der Unterkonstruktion zu verlassen, während der Abstand zwischen der Unterkonstruktion der dieser zugewandten Oberfläche konstant bleiben soll. Auch solche Aufgaben lassen sich mit den bekannten Isolierelementen ebenfalls nicht lösen.The insulating glass panes and insulating facade elements known from the prior art have panes arranged essentially parallel to one another. With such insulating elements, either only flat surfaces or small surface curvatures can be produced, or a strongly curved surface has to be simulated with relatively small-area individual elements. In some cases, it may also be desirable to leave with the outer surface of the insulating the course of the substructure, while the distance between the substructure of this facing surface should remain constant. Even such tasks can not be solved with the known insulating also.

Der Erfindung liegt die Aufgabe zugrunde, die Gestaltungsmöglichkeiten mit Isolier-Scheibenelementen zu verbessern.The invention has for its object to improve the design options with insulating disk elements.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst. Der nebengeordnete Anspruch 14 bezieht sich auf eine Fassade mit solchen Isolier-Scheibenelementen. Die Merkmale der den unabhängigen Ansprüchen jeweils nachgeordneten Unteransprüche geben vorteilhafte Weiterbildungen dieser Erfindung an.This object is achieved with the features of claim 1. The independent claim 14 refers to a facade with such insulating disc elements. The features of the independent claims each subordinate claims indicate advantageous developments of this invention.

Das erfindungsgemäße lsolier-Scheibenelement zeichnet sich dadurch aus, dass die Scheiben nicht wie üblich im Wesentlichen parallel zueinander angeordnet sind, sondern den Erfordernissen am jeweiligen Einsatzort entsprechend beliebige Lagen zueinander einnehmen können. Die Anordnung der Scheiben in stark in der Lage voneinander abweichenden Ebenen ist gleichbedeutend mit der Tatsache, dass zumindest ein Randbereich des Isolier-Scheibenelements, der für die Verbindung mittels eines Profilstabs des Abstandshalter-Rahmens vorgesehen ist, ein Randspalt mit einem (in Blickrichtung auf die Scheibenkante) nicht rechteckigem Querschnitt entsteht. Es können also in diesem Bereich nicht die üblichen Profilstäbe mit einem konstanten Querschnitt und eventuell stärker bemessenen Kleberschichten zur Verbindung mit den Scheiben eingesetzt werden. Gemäß der Erfindung wird stattdessen ein Vollprofilstab eingesetzt, dessen Abmessungen denjenigen des zwischen den Scheiben gebildeten Spalts entsprechen.The insulating disk element according to the invention is characterized in that the disks are not arranged, as usual, essentially parallel to one another, but instead can occupy any desired position relative to one another at the respective place of use. The arrangement of the disks in highly divergent planes is equivalent to the fact that at least one edge region of the insulating disk element, which is provided for connection by means of a profile bar of the spacer frame, an edge gap with a (in the direction of the Pane edge) of non-rectangular cross section. It can not be used in this area, the usual profile bars with a constant cross-section and possibly more sized adhesive layers for connection to the discs. According to the invention, instead, a solid profile bar is used whose dimensions correspond to those of the gap formed between the panes.

Dieser die Kontur des Spalts besitzende Vollprofilstab kann besonders vorteilhaft aus einem sprödbrüchigen Material, wie beispielsweise Glas, Keramik oder Glaskeramik hergestellt werden. Diese Werkstoffe lassen sich nämlich ein einfach durch Anritzen und Brechen entlang dieser Vorschädigung der gewünschten Form anpassen. Eine aufwändige Schneide- oder Fräsbearbeitung kann so in den meisten Fällen vermieden werden.This full profile bar having the contour of the gap can be produced particularly advantageously from a brittle material such as, for example, glass, ceramic or glass ceramic. Namely, these materials can be easily adjusted by scratching and breaking along this pre-damage of the desired shape. An elaborate cutting or milling can be avoided in most cases.

Ein nicht rechteckiger Spalt in Randbereichen des Isolier-Scheibenelements kann aufgrund einer Vielzahl von Formen oder Anordnungen der Einzelscheiben entstehen. Die einfachste Anordnung wird aus zwei planen Scheiben gebildet, die einen Winkel zwischen sich einschließen. In diesem Fall werden zwei Vollprofilstäbe mit einem im Wesentlichen dreieckigen Querschnitt und zwei Profilstäbe mit einem rechteckigen Querschnitt benötigt. Die Profilstäbe mit dem rechteckigen Querschnitt können dabei sowohl die üblichen Hohlprofilstäbe als auch Vollprofilstäbe sein. Insbesondere wenn einer der Profilstäbe einen rechteckigen Querschnitt mit einer verhältnismäßig großen Höhe aufweist, kann die Verwendung eines Vollprofilstabs vorteilhaft sein. Wenn zwei plane Scheiben in zueinander bezüglich mehrerer Seitenkanten schräg liegenden Ebenen angeordnet sind, müssen alle Profilleisten einen dreieckigen oder trapezförmigen Querschnitt aufweisen.A non-rectangular gap in edge regions of the insulating disk element may arise due to a variety of shapes or arrangements of the individual disks. The simplest arrangement is made up of two flat disks enclosing an angle between them. In this case, two solid profile bars with a substantially triangular cross section and two profile bars with a rectangular cross section are required. The profile bars with the rectangular cross section can be both the usual hollow profile bars and solid profile bars. In particular, if one of the profile bars has a rectangular cross-section with a relatively large height, the use of a solid profile bar may be advantageous. If two plane disks are arranged in planes which are inclined with respect to each other with respect to a plurality of side edges, all profile strips must have a triangular or trapezoidal cross section.

Obwohl hier der Einfachheit halber von "Stäben" oder "Leisten" die Rede ist, so können diese doch auch Streifen- bzw. Flächenform haben, insbesondere wenn der Randspalt zwischen den Scheiben verhältnismäßig hoch ist.Although the term "bars" or "bars" is mentioned here, they may also have strip or surface shape, in particular if the marginal gap between the panes is relatively high.

Es können aber auch eine plane und eine gebogene Scheibe oder zwei gebogene Scheiben miteinander zu einem erfindungsgemäßen Isolier-Scheibenelement verbunden werden. In diesen Fällen werden die Vollprofilstäbe für die Randspalte mit nicht rechteckigem Querschnitt zumindest einseitig von einem Bogen begrenzt. Der Bogen kann auch ein-oder mehrfach seine Krümmungsrichtung ändern, so dass beispielsweise auch ein- oder mehrfach S-förmige Randspalte gebildet werden.But it can also be a plane and a curved disc or two curved discs are joined together to form an insulating disc element according to the invention. In these cases, the solid profile bars for the marginal gaps with non-rectangular cross section are bounded at least on one side by an arc. The bow can also one or more times change its direction of curvature, so that, for example, one or more S-shaped edge gaps are formed.

Wenn eine plane Scheibe mit einer zylinderförmig gebogenen Scheibe oder zwei zylinderförmig gebogene Scheiben ein Isolier-Scheibenelement bilden, können die Randspalte, die parallel zur Zylinderachse verlaufen, mit üblichen Abstandshalterprofilen versehen werden.If a flat disc with a cylindrically curved disc or two cylindrically curved discs form an insulating disc element, the marginal gaps, which run parallel to the cylinder axis, can be provided with conventional spacer profiles.

Bei allen Varianten der erfindungsgemäßen Isolier-Scheibenelemente kann es erforderlich sein, ein Trockenmittel zur Vermeidung von Kondenswasser in dem abgeschlossenen Raum zwischen den Scheiben vorzusehen. Wenn einer der Profilstäbe ein übliches Hohlprofil mit integriertem Trockenmittel und Öffnungen zum Scheibenzwischenraum ist, kann im Allgemeinen auf weitere Maßnahmen zur Vermeidung von Kondensniederschlägen verzichtet werden. Falls jedoch ausschließlich Vollprofilstäbe verwendet werden, muss eventuell ein Mittel zum Trocknen des Gases im Scheibenzwischenraum angeordnet werden. Dies kann beispielsweise ein ein Trockenmittel enthaltender Hohlkörper mit Öffnungen zum Scheibenzwischenraum sein, der auf einen Vollprofilstab aufgeklebt ist.In all variants of the insulating disc elements according to the invention, it may be necessary to provide a desiccant to prevent condensation in the closed space between the panes. If one of the profile bars is a common hollow profile with integrated desiccant and openings to the space between the panes, generally further measures can be taken to avoid condensation be waived. However, if only full profile bars are used, then a means for drying the gas may need to be placed in the space between the panes. This may for example be a desiccant containing hollow body with openings to the space between the panes, which is glued to a solid profile bar.

Die Einzelscheiben des erfindungsgemäßen Isolier-Scheibenelements können aus Glas, vorgespanntem Glas, Kunststoff oder jedem anderen geeigneten Material bestehen. Die Scheiben können klar transparent, durchscheinend oder opak sein. Bei transparenten oder durchscheinenden Scheiben kann es sinnvoll sein, die Randbereiche, in denen der Abstandshalter-Rahmen angeordnet ist, mit einer die Durchsicht hemmenden oder opaken Farbschicht zu versehen. Mit dieser Maßnahme ist dann sowohl die Sicht auf Klebe- und/oder Dichtmittel versperrt, als auch werden diese Klebe- und/oder Dichtmittel vor eventuell schädlicher (Sonnen-) Strahlung geschützt. Der Zwischenraum des Isolier-Scheibenelements kann mit den üblicherweise verwendeten, den Wärmefluss hemmenden oder den Schall dämpfenden Gasen gefüllt oder auch teilevakuiert sein.The individual panes of the insulating disc element according to the invention may consist of glass, toughened glass, plastic or any other suitable material. The panes can be clear, translucent or opaque. In the case of transparent or translucent panes, it can be useful to provide the edge areas in which the spacer frame is arranged with a color layer which inhibits transparency or opaque. With this measure, both the view of adhesive and / or sealant is then blocked, as well as these adhesives and / or sealants are protected from any harmful (solar) radiation. The interspace of the insulating disk element can be filled with the commonly used, the heat flow inhibiting or the sound-absorbing gases or also partially evacuated.

Das erfindungsgemäße Isolier-Scheibenelement ist besonders dafür geeignet, in eine Fassade eingebaut zu werden. Insbesondere die Ausführungen mit gebogenen Scheiben können die Anforderung an geschwungene Formen und abgerundete Eckbereiche an Gebäuden besonders gut erfüllen.The insulating disc element according to the invention is particularly suitable to be installed in a facade. In particular, the versions with curved discs can meet the requirement for curved shapes and rounded corner areas of buildings particularly well.

Weitere Einzelheiten und Vorteile des Gegenstands der Erfindung gehen ohne Absicht einer Einschränkung aus der Zeichnung eines Ausführungsbeispiels und deren sich im folgenden anschließender eingehender Beschreibung hervor.Further details and advantages of the subject matter of the invention will become apparent without any intention to be bound by the drawing of an embodiment and its detailed description which follows.

and
Fig. 2
a second embodiment, also in section, in which a plane and a curved disc are connected to an insulating disc element.

Gemäß Fig. 1 besteht ein Isolier-Scheibenelement 1 aus zwei Glasscheiben 20 und 21, die in ihren Randbereichen miteinander verbunden sind. Die Glasscheiben 20 und 21 schließen einen Winkel zwischen sich ein, das Isolierscheibenelement 1 besitzt also die Form eines Keils. 1 , an insulating disk element 1 consists of two glass panes 20 and 21, which are interconnected in their edge regions. The glass sheets 20 and 21 enclose an angle therebetween, that is, the insulating disk member 1 has the shape of a wedge.

Die Profilstäbe 30 und 31 sind aus dem Stand der Technik bekannte Aluminium-Hohlprofile, welche in ihrem Innern ein hygroskopisches Trockenmittel zur Entfeuchtung des zwischen den Glasscheiben 20 und 21 eingeschlossenen Raums enthalten. Es können natürlich auch bekannte Hohlprofile aus Stahl, Edelstahl, Kunststoff oder anderen geeigneten Materialien verwendet werden. Damit das Trocknungsmittel seine Wirkung entfalten kann, müssen selbstverständlich Öffnungen zum Scheibenzwischenraum hin vorgesehen sein. Zusammen mit zwei weiteren als Vollprofile ausgeführte Profilstäben 32 bilden die Profilstäbe 30 und 31 einen Abstandshalter-Rahmen für das Isolier-Scheibenelement. Die Profilstäbe 32 bestehen aus entsprechend dem Keilwinkel zugeschnittenen Glasstreifen. Die Profilstäbe 30, 31 und 32 sind mit einem üblichen Klebstoff 4 an ihren Ecken und mit den Glasscheiben 20 und 21 fest verbunden. Als Klebstoff 4 kann beispielsweise Silikon oder Butyl verwendet werden. Der Klebstoff 4 wird in einer solchen Stärke aufgetragen, dass die Abweichungen von einem rechten Winkel zwischen den rechtwinkligen Profilstäben 30 und 31 und der geneigten Glasscheibe 21 ausgeglichen werden.The profile bars 30 and 31 are known from the prior art aluminum hollow profiles, which contain in their interior a hygroscopic desiccant for dehumidifying the enclosed between the glass sheets 20 and 21 space. Of course, known hollow profiles made of steel, stainless steel, plastic or other suitable materials can be used. Of course, openings for the space between the panes must be provided in order for the desiccant to be effective. Together with two other profiled bars 32 designed as solid profiles, the profiled bars 30 and 31 form a spacer frame for the insulating pane element. The profile bars 32 consist of cut according to the wedge angle glass strip. The profile bars 30, 31 and 32 are fixedly connected to a conventional adhesive 4 at their corners and with the glass sheets 20 and 21. As the adhesive 4, for example, silicone or butyl can be used. The adhesive 4 is applied in such a thickness that the deviations from a right angle between the rectangular profile bars 30 and 31 and the inclined glass plate 21 are compensated.

Falls die Gasdichtigkeit des Klebstoffs 4 für den Anwendungsfall des Isolier-Scheibenelements nicht ausreicht, kann die äußere Fuge zwischen den miteinander verbundenen Glasscheiben 20, 21 mittels eines Sekundärdichtstoffes 5 zusätzlich abgedichtet. Als Sekundärdichtstoff kann beispielsweise ein Silikon oder Polysulfid eingesetzt werden.If the gas-tightness of the adhesive 4 is insufficient for the application of the insulating disk element, the outer joint between the interconnected glass panes 20, 21 can be additionally sealed by means of a secondary sealant 5. As a secondary sealant, for example, a silicone or polysulfide can be used.

Fig. 2 zeigt ein Isolier-Scheibenelement 10, das prinzipiell den gleichen Aufbau wie das Isolier-Scheibenelement aus Fig. 1 besitzt. In diesem Fall sind lediglich eine plane Glasscheibe 210 und eine zylindrisch gebogene Glasscheibe 200 miteinander verbunden. Die Profilstäbe 300 und 310 aus mit einem hygroskopischen Mittel gefüllten Aluminium-Hohlprofilen und die aus Glasleisten bestehenden Vollprofilstäbe 320 bilden wiederum den Abstandshalter-Rahmen. Als Klebstoff 40 dient Butyl, als Sekundärdichtstoff 50 Polysulfid.FIG. 2 shows an insulating disk element 10, which in principle has the same structure as the insulating disk element from FIG. 1. In this case, only a flat glass sheet 210 and a cylindrically curved glass sheet 200 are bonded together. The profile bars 300 and 310 made of aluminum hollow profiles filled with a hygroscopic agent and the solid profile bars 320 consisting of glazing beads in turn form the spacer frame. Butyl is used as adhesive 40, polysulphide as secondary sealant 50.

Auch wenn in den Darstellungen die äußere Kontur der Isolier-Scheibenelemente ein Rechteck ist, können selbstverständlich Isolier-Scheiben-Elemente mit jeder beliebigen äußeren Form hergestellt werden, zum Beispiel Dreiecke, Fünfecke, Sechsecke und so weiter. Selbst runde, ovale oder mit einem oder mehreren Bögen versehe Isolier-Scheibenelemente sind machbar. Sowohl die aus dem Stand der Technik bekannten hohlen Aluminiumprofile als auch Vollprofile aus Glas oder Keramik lassen sich als in der Isolier-scheiben-Ebene gebogene Profile fertigen.Although in the illustrations, the outer contour of the insulating disk elements is a rectangle, it goes without saying that insulating disk elements of any external shape can be made, for example, triangles, pentagons, hexagons, and so forth. Even round, oval or with one or more sheets versehe-disc elements are feasible. Both the hollow aluminum profiles known from the prior art and solid profiles made of glass or ceramic can be produced as profiles bent in the insulating pane plane.

Zum Herstellen von Fassaden mit den vorstehend beschriebenen Scheibenelementen werden diese in an sich herkömmlicher Weise entweder an ihren Außenrändern oder in ihren Flächen mit Haltebeschlägen verbunden, die ihrerseits an einer Unterkonstruktion der Fassade befestigt werden. Auf die Art dieser Befestigungen muss hier jedoch nicht näher eingegangen werden, da dem Fachmann eine Vielzahl von verwendbaren Ausführungen aus dem Stand der Technik geläufig ist.For the manufacture of facades with the disk elements described above, these are connected in a conventional manner either at their outer edges or in their surfaces with retaining fittings, which in turn are attached to a substructure of the facade. But you do not have to go for the kind of fixings here will be discussed in more detail, as the expert is familiar with a variety of usable versions of the prior art.
