Abstract

The glass unit (1) has a foil (22) arranged between two outer panes (2, 3). An edge connection comprises a spacer profile (5). The spacer profile has two opposed contact faces (12) that are connected in a shear-resistant manner to the outer panes via an adhesive layer (11). One of the contact faces exhibits a pressure balance between the foil and pane interspaces (25, 26). The contact faces are adhesively bonded to the outer panes with a shear-resistant ionoplast polymer. The spacer profile is constructed from a high-strength glass-fiber-reinforced plastic.

Description

Die vorliegende Erfindung betrifft eine Isolierglasscheibe, bestehend aus zwei Außenscheiben, mindestens einer Einzelscheibe oder Folie, welche zwischen den zwei Außenscheiben angeordnet ist, und einem Randverbund, welcher ein Abstandsprofil aufweist.The present invention relates to an insulating glass pane consisting of two outer panes, at least one single pane or foil, which is arranged between the two outer panes, and an edge composite, which has a spacing profile.

Eine derartige Isolierglasscheibe ist dem Prinzip nach allgemein aus dem Stand der Technik bekannt. Sie enthält die zwei Außenscheiben, wobei im allgemeinen eine erste Außenscheibe im Inneren eines Raumes, eines Hauses, einer Lagerhalle oder allgemein eines Gebäudes angeordnet ist und eine zweite Außenscheibe außerhalb des Gebäudes angeordnet sind. Innerhalb der zwei Außenscheiben ist ein thermisch isolierender Zwischenraum angeordnet. Der Vorteil liegt insbesondere im größeren Wärme- und Schallschutz. Die Isolierglasscheibe bildet daher heute die gängige Art und Weise der Verglasung. Im Normalfall besteht der Randverbund aus einem Hohlprofil aus Metall oder Kunststoff, in dem ein Trockenmittel für die Funktion der Trocknung der im Zwischenraum eingeschlossenen Luft der Isolierglasscheibe untergebracht ist. Zur Außenseite hin wird noch eine zusätzliche Abdichtung aus Silikon oder Polysulfid angebracht. Im Allgemeinen übernimmt der Randverbund keine statische Funktion. Bei Belastung verhält sich die Isolierglasscheibe statisch mehr oder weniger wie zwei Außenscheiben. Die bisherigen Abstandshalter, wie auch die bisherigen Abdichtungsmaterialien, sind nicht in der Lage, die beiden Außenscheiben soweit schubfest miteinander zu verbinden, dass die beiden Außenscheibe ohne sichtbare Stützprofile getragen werden können.Such an insulating glass pane is known in principle from the prior art. It contains the two outer panes, wherein generally a first outer pane is arranged inside a room, a house, a warehouse or generally a building, and a second outer pane is arranged outside the building. Within the two outer panes, a thermally insulating space is arranged. The advantage lies especially in the larger heat and sound insulation. The insulating glass is therefore today the common type and way of glazing. Normally, the edge seal consists of a hollow profile made of metal or plastic, in which a desiccant for the function of drying the trapped air in the space of the insulating glass is housed. To the outside, an additional seal made of silicone or polysulfide is attached. In general, the marginal composite does not assume any static function. Under load, the insulating glass pane behaves statically more or less like two outer panes. The previous spacers, as well as the previous sealing materials, are not able to push the two outer sheaves as far as shove-proof together that the two outer pane can be worn without visible support profiles.

Auf Grundlage dieser Problemstellung liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Isolierglasscheibe der eingangs genannten Art dahingehend weiterzubilden, dass die Isolierglasscheibe eine selbst tragende Struktur aufweist, sodass auf sichtbare Stützprofile zum Tragen der Isolierglasscheibe verzichtet oder diese zumindest deutlich reduziert werden können.Based on this problem, the present invention seeks to further develop an insulating glass pane of the type mentioned in that the insulating glass has a self-supporting structure, so that dispensed visible support profiles for supporting the insulating glass or these can be at least significantly reduced.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, dass bei einer Isolierglasscheibe der eingangs genannten Art das Abstandsprofil zwei gegenüberliegende Kontaktflächen aufweist, welche mit den Außenscheiben über eine Klebeschicht schubfest verbunden sind und mindestens einer der beiden zwischen der Einzelscheibe oder Folie und den zwei Außenscheiben gebildeten Scheibenzwischenräume einen Druckausgleich aufweist.To achieve this object, the invention proposes that, in an insulating glass pane of the type mentioned, the spacer profile has two opposite contact surfaces which are shear-resistant connected to the outer plates via an adhesive layer and at least one of the two disc spaces formed between the single pane or film and the two outer panes Pressure equalization has.

Die mit der erfindungsgemäßen Lösung erzielbaren Vorteile liegen auf der Hand. Durch den Druckausgleich wird der Druck im Scheibenzwischenraum bei Erwärmung oder Abkühlung möglichst gleich belassen. Im Randbereich der Scheiben entstehen besonders aufgrund der Klimalasten starke Winkelveränderungen an den Kontaktflächen. Je nach Steifigkeit der Kleber führt das zu mehr oder weniger starken Einspannungen, und damit zu hohen Zugspannungen an den Rändern der Verklebungen, welche zu einer Überbelastung der Verklebung führen können. Um hier die Zugspannungen auf ein vernünftiges Maß zu reduzieren, wird erfindungsgemäß vorgeschlagen, dass mindestens einer der beiden zwischen der Einzelscheibe oder Folie und den zwei Außenscheiben gebildeten Scheibenzwischenräume drucktechnisch mit der Atmosphäre verbunden ist. Dies wird dadurch erzielt, indem mindestens einer der Scheibenzwischenräume einen Druckausgleich aufweist. Ein gleichbelassener Druck im Scheibenzwischenraum bedeutet vorteilhaft, dass keine Winkeländerungen und somit auch keine Zugspannungen im Bereich der Verklebungen am Randverbund auftreten.The achievable with the inventive solution advantages are obvious. Due to the pressure compensation, the pressure in the space between the panes is kept as constant as possible during heating or cooling. In the edge region of the panes, particularly due to the climatic loads, strong angle changes occur at the contact surfaces. Depending on the stiffness of the adhesive leads to more or less strong restraints, and thus high tensile stresses at the edges of the bonds, which can lead to an overload of the bond. In order to reduce the tensile stresses to a reasonable level, the invention proposes that at least one of the two be between the Single pane or film and the two outer panes formed disc spaces printing technology is connected to the atmosphere. This is achieved by at least one of the disc spaces having a pressure equalization. An equal pressure in the space between the panes advantageously means that no angle changes and thus no tensile stresses in the region of the bonds at the edge bond occur.

Vorzugsweise ist die Einzelscheibe oder Folie relativ dünn ausgeführt und kann sich bei Druckänderungen nach innen oder außen ausbauchen. Durch den Druck baucht sich die innere Einzelscheibe in Richtung eines Scheibenzwischenraumes aus. Je dünner die Einzelscheibe ist, desto mehr kann sie sich ausbauchen. Hierdurch stellt sich im Scheibenzwischenraum nur eine geringe Druckerhöhung ein.Preferably, the single disc or foil is made relatively thin and may bulge inward or outward when pressure changes. Due to the pressure, the inner single disc bulges in the direction of a space between the panes. The thinner the single pane, the more it can bulge out. As a result, there is only a slight pressure increase in the space between the panes.

Der Druckausgleich erfolgt über eine Öffnung oder über ein Druckausgleichsröhrchen, welches den mindestens einen Scheibenzwischenraum mit der Atmosphäre verbindet. Bevorzugt erfolgt der Druckausgleich über die Atmosphäre der Außenluft, da sie im Regelfall immer trockener als beheizte Raumluft ist. Mit Außenluft ist hier die Luft außerhalb des Gebäudes gemeint.The pressure equalization takes place via an opening or via a pressure equalization tube, which connects the at least one space between the panes with the atmosphere. Preferably, the pressure equalization takes place via the atmosphere of the outside air, since it is usually always drier than heated room air. With outside air here is meant the air outside the building.

Bevorzugt ist ein innerer Scheibenzwischenraum, welcher zum Innenraum hin ausgerichtet ist, mit der Atmosphäre der Außenluft verbunden und ist ein äußerer Scheibenzwischenraum, welcher zur Außenluft hin ausgerichtet ist, hermetisch verschlossen. Dadurch, dass der äußere Scheibenzwischenraum hermetisch dicht geschlossen ist erhöht sich hier der Druck, wodurch sich die innere Zwischenscheibe in Richtung des inneren Scheibenzwischenraumes hin ausbaucht. Hierdurch stellt sich im äußeren Scheibenzwischenraum nur eine geringe Druckerhöhung ein.Preferably, an inner space between the panes, which is aligned with the interior, is connected to the atmosphere of the outside air, and an outer space between the panes, which is aligned with the outside air, is hermetically sealed. As a result of the fact that the outer space between the panes is hermetically sealed, the pressure increases, as a result of which the inner intermediate pane bulges out in the direction of the inner space between the panes. As a result, only a slight pressure increase occurs in the outer space between the panes.

Vorzugsweise ist das Volumen des äußerer Scheibenzwischenraumes kleiner als das Volumen des inneren Scheibenzwischenraumes. Durch diese Ausgestaltung wird die Druckerhöhung weiter reduziert. Dies hat zur Folge, dass jegliche Volumenänderungen und Temperaturänderungen im inneren Scheibenzwischenraum keine bzw. nur geringe Druckveränderungen zur Folge haben.Preferably, the volume of the outer pane space is smaller than the volume of the inner pane space. By this configuration, the pressure increase is further reduced. As a result, any volume changes and temperature changes in the inner space between the panes will result in no or only slight pressure changes.

Das Abstandsprofil besteht aus einem hochfesten Kunststoffmaterial, insbesondere aus einem glasfaserverstärkten Kunststoff. Dadurch wird in vorteilhafter Weise ein Material verwendet, welches einen relativ kleinen Wärmeleitwert besitzt und trotzdem über hohe Festigkeiten verfügt. Ein weiterer Vorteil liegt im Wärmeausdehnungskoeffizienten, dieser ist zwischen Glas und glasfaserverstärktem Kunststoff sehr ähnlich. Dies ist wichtig da hier dann keine zusätzlichen Kräfte aufgrund unterschiedlicher Längendehnung entstehen.The spacer profile consists of a high-strength plastic material, in particular of a glass fiber reinforced plastic. As a result, a material is used which has a relatively low thermal conductivity and still has high strengths in an advantageous manner. Another advantage lies in the thermal expansion coefficient, which is very similar between glass and glass fiber reinforced plastic. This is important because there are no additional forces due to different elongation.

Die Anbindung des Abstandsprofils kann entweder durch entsprechend hochfeste Kleber erfolgen oder durch hochfeste Verbundfolien. Der hochfeste Kleber oder die hochfeste Verbundfolie kann beispielsweise aus einem Polymer, z. B. Polyvinylbutyral, Ionoplast (Polymer), teilkristallinem Thermoplast oder einem anderen Material bestehen, welches die erforderliche Klebefestigkeit, Dauerhaftigkeit und Wärmestabilität hat. Durch den Verbund des Abstandsprofils mit den Außenscheiben kann hier ein nahezu monolithisches Tragverhalten des Randbereiches erreicht werden. Obwohl bereits einige hochfeste Kleber für den Fassadenbereich zur Verfügung stehen, ist eine Verklebung im Randbereich nur möglich, wenn die dort verwendeten Profile an diese speziellen Anforderungen angepasst sind.The connection of the spacer profile can be done either by appropriately high-strength adhesive or by high-strength composite films. The high-strength adhesive or the high-strength composite film may for example consist of a polymer, for. As polyvinyl butyral, ionoplast (polymer), semi-crystalline thermoplastic or other material, which has the required adhesive strength, durability and thermal stability. By combining the distance profile with the outer panes, a nearly monolithic load-bearing behavior of the edge area can be achieved here. Although some high-strength adhesives are already available for the façade area, gluing in the edge area is only possible if the profiles used there are adapted to these special requirements.

In einer möglichen Realisierung der erfinderischen Lösung kommt ein zähelastischer Zweikomponenten-Klebstoff auf Expoxidharzbasis zum Einsatz. Derartige Klebstoffe weisen gegenüber den Klebeoberflächen eine Zugscherfestigkeit von mindestens 10/mm2 auf und sein E-Modul unter kurzzeitiger Belastung ist größer als 1000 N/mm2.In one possible implementation of the inventive solution, a viscoelastic, two-component adhesive based on epoxy resin is used. Such adhesives have a tensile shear strength of at least 10 / mm 2 compared to the adhesive surfaces and its modulus of elasticity under short-term loading is greater than 1000 N / mm 2 .

Das Abstandsprofil weist zwei gegenüberliegende Kontaktflächen auf, welche relativ gleichmäßig dick ausgeführt sind, um dort einen gleichmäßigen Spannungsverlauf in der Klebeschicht zu erzeugen. Durch diese Anordnung wird erreicht, dass sich im Bereich der Kontaktflächen die Spannungen verringern und dadurch die Belastung des Klebstoffes reduziert wird.The spacer profile has two opposite contact surfaces, which are made relatively uniformly thick, in order to produce a uniform voltage curve in the adhesive layer there. By means of this arrangement it is achieved that the stresses in the area of the contact surfaces are reduced, thereby reducing the load on the adhesive.

Das Abstandsprofil kann weiterhin so gestaltet sein, dass ein oder mehrere Trockenmittel, beispielsweise in einem oder mehreren Hohlräumen des Profils, integriert sind. In einer weiteren Ausführungsform kann jedes der Trockenmittel auch in einem zusätzlichen Trockenmittelprofil untergebracht sein. Es können aber auch handelsübliche Abstandsprofile mit Trockenmittel verbaut werden.The spacing profile may also be designed such that one or more drying agents, for example in one or more cavities of the profile, are integrated. In a further embodiment, each of the desiccants can also be accommodated in an additional desiccant profile. But it can also be installed commercially available spacer profiles with desiccant.

Vorzugsweise ist ein zusätzliches Profil als Zwischenlage zwischen den Kontaktflächen des Abstandsprofils und den Außenscheiben mit Hilfe eines transparenten Klebers oder einer transparenten Folie an mindestens einer der beiden Außenscheiben befestigt.Preferably, an additional profile is attached as an intermediate layer between the contact surfaces of the spacer profile and the outer panes with the aid of a transparent adhesive or a transparent film on at least one of the two outer panes.

Figur 1 zeigt eine Querschnittsansicht auf den Randbereich einer Isolierglasscheibe 1 gemäß einer Ausführungsform der Erfindung, wobei ein innerer Scheibenzwischenraum 26 einen Druckausgleich aufweist und eine Einzelscheibe 22 zwischen zwei Profilteilen 5a, 5b eines Abstandsprofils 5 gehalten ist. Die erfindungsgemäße Isolierglasscheibe 1enthält mindestens zwei Außenscheiben 2, 3 und einen Randverbund 4, welcher das Abstandsprofil 5 aufweist, welches in dieser Ausführungsform aus zwei Profilteilen 5a, 5b besteht. Das Abstandsprofil 5 besteht aus einem hochfesten Kunststoff und weist zwei gegenüberliegende Kontaktflächen 12 auf. Die beiden Kontaktflächen 12 sind mit den jeweiligen Innenseiten der beiden Außenscheiben 2, 3 schubfest verbunden. Hierzu ist es denkbar, eine Klebeschicht 11 vorzusehen, die diesen schubfesten Verbund zwischen dem Abstandsprofil 5 und den Außenscheiben 2, 3 bereitstellt. Da die Einzelscheibe oder Folie 22 hier zwischen den zwei Außenscheiben 2, 3 angeordnet ist, werden durch diesen Aufbau ein innerer Scheibenzwischenraum 26, welcher zum Innenraum hin ausgerichtet ist, und ein äußerer Scheibenzwischenraum 25, welcher zur Außenluft hin ausgerichtet ist, ausgebildet. Der innere Scheibenzwischenraum 26 weist einen Druckausgleich auf, welcher über ein Druckausgleichsröhrchen 27 erfolgt, welches den inneren Scheibenzwischenraum 26 mit der Atmosphäre der Außenluft verbindet. Der äußere Scheibenzwischenraum 25 ist hermetisch verschlossen. In dieser Ausführungsform ist die Einzelscheibe oder Folie 22 durch die zwei Profilteile 5a, 5b gehalten. An den Kontaktstellen zwischen der Einzelscheibe oder Folie 22 und den Profilteilen 5a, 5b ist jeweils eine Dichtung vorgesehen. Obwohl in der Figur nicht angezeigt, ist das Volumen des äußeren Scheibenzwischenraumes 25 vorzugsweise kleiner als das Volumen des inneren Scheibenzwischenraumes 26. Hierdurch stellt sich im äußeren Scheibenzwischenraum 25 nur eine geringe Druckerhöhung ein. FIG. 1 shows a cross-sectional view of the edge region of an insulating glass pane 1 according to an embodiment of the invention, wherein an inner space between the panes 26 has a pressure equalization and a single disc 22 between two profile parts 5a, 5b of a spacer profile 5 is held. The insulating glass pane 1 according to the invention contains at least two outer panes 2, 3 and a marginal composite 4, which has the spacing profile 5, which consists in this embodiment of two profile parts 5a, 5b. The spacer profile 5 consists of a high-strength plastic and has two opposite contact surfaces 12. The two contact surfaces 12 are connected shear-resistant with the respective inner sides of the two outer disks 2, 3. For this purpose, it is conceivable to provide an adhesive layer 11 which provides this shear-resistant composite between the spacer profile 5 and the outer panes 2, 3. Since the single disc or foil 22 is arranged here between the two outer panes 2, 3, this construction forms an inner pan space 26, which is oriented towards the inner space, and an outer pan space 25, which is oriented towards the outside air. The inner space between the panes 26 has a pressure equalization, which takes place via a pressure equalizing tube 27, which connects the inner pane space 26 with the atmosphere of the outside air. The outer space between the panes 25 is hermetically sealed. In this embodiment, the single disc or foil 22 is held by the two profile parts 5a, 5b. At the contact points between the single disc or film 22 and the profile parts 5a, 5b, a seal is provided in each case. Although not indicated in the figure, the volume of the outer space between the panes 25 is preferably smaller than the volume of the inner space between the panes. As a result, only a slight increase in pressure occurs in the outer pan space 25.

Bei der in der Figur dargestellten Ausführungsform ist es möglich, dass die einzelnen Profilteile 5a, 5b zunächst auf die Außenscheiben 2, 3 aufgeklebt werden. Dies hat den Vorteil, dass beim Aufkleben der Profilteile 5a, 5b, zunächst auf die Innenflächen der Außenscheiben 2, 3, diese von allen Seiten zugänglich sind und somit ggf. austretende Klebereste noch entfernt werden können.In the embodiment shown in the figure, it is possible that the individual profile parts 5a, 5b are first glued to the outer panes 2, 3. This has the advantage that when gluing the profile parts 5a, 5b, first on the inner surfaces of the outer panes 2, 3, they are accessible from all sides and thus possibly exiting adhesive residues can still be removed.

Figur 2 zeigt die in Figur 1 dargestellte Ausführungsform, wobei die Einzelscheibe oder Folie 22 hier durch zwei Halteprofile 9 gehalten ist, welche jeweils zwischen der Einzelscheibe oder Folie 22 und den Außenscheiben 2, 3 eingespannt sind. An den Kontaktstellen zwischen der Einzelscheibe oder Folie 22 und den Halteprofilen 9 sowie zwischen den Außenscheiben 2, 3 und den Halteprofilen 9 ist jeweils eine Dichtung vorgesehen. In dieser Ausführungsform ist das Abstandsprofil 5 einstückig ausgebildet. FIG. 2 shows the in FIG. 1 illustrated embodiment, wherein the single disc or film 22 is held here by two retaining profiles 9, which are respectively clamped between the single disc or foil 22 and the outer discs 2, 3. At the contact points between the single disc or film 22 and the holding profiles 9 and between the outer plates 2, 3 and the holding profiles 9 is one each Seal provided. In this embodiment, the spacer profile 5 is integrally formed.

Bei einer normalen Isolierglasscheibe wird bewusst der Scheibenzwischenraum hermetisch abgedichtet. Die Luft bzw. das Gas im Scheibenzwischenraum wird durch spezielles Trockenmittel 10 möglichst trocken gehalten. Das ist notwendig, damit bei Temperaturwechsel, insbesondere wenn die Außenscheibe nach draußen hin abkühlt, keine Kondensation auf der Innenseite stattfindet. In dieser Ausführungsform ist das Trockenmittel 10 in den Halteprofilen 9 enthalten.In the case of a normal insulating glass pane, the space between the panes is deliberately hermetically sealed. The air or the gas in the space between the panes is kept as dry as possible by special desiccant 10. This is necessary so that when the temperature changes, especially when the outer pane cools to the outside, no condensation takes place on the inside. In this embodiment, the desiccant 10 is contained in the holding profiles 9.

Im Folgenden wird die Funktionsweise des Druckausgleiches näher erläutert. Im Einzelnen ist bei diesen Ausführungsformen vorgesehen, die Belastungen auf die Klebeschicht 11 zwischen den Kontaktflächen 12 und den Außenscheiben 2, 3 aufgrund der Klimalasten dadurch zu reduzieren, indem der innere Scheibenzwischenraum 26 nach außen geöffnet wird, wodurch der Druckausgleich ermöglicht wird.The following describes the operation of the pressure equalization. Specifically, it is provided in these embodiments to reduce the stresses on the adhesive layer 11 between the contact surfaces 12 and the outer panes 2, 3 due to the climatic loads by opening the inner pane clearance 26 to the outside, thereby allowing pressure equalization.

Hiermit ist es dann möglich, bei Erwärmung oder Abkühlung den Druck im Scheibenzwischenraum 26 möglichst gleich zu lassen. Gleichbleibender Druck im Scheibenzwischenraum 26 bedeutet, dass keine Winkeländerungen im Bereich der Klebeschicht 11 auftreten. Das Öffnen des Scheibenzwischenraumes einer Isolierglaseinheit widerspricht jedoch der bisherigen Isolierglastechnik.Hereby it is then possible to leave the pressure in the space between the panes 26 as equal as possible during heating or cooling. Constant pressure in the space between the panes 26 means that no angle changes occur in the area of the adhesive layer 11. However, the opening of the space between the panes of an insulating glass unit contradicts the previous insulating glass technique.

Bei normalem Isolierglas wird bewusst der Scheibenzwischenraum hermetisch abgedichtet. Die Luft bzw. das Gas im Scheibenzwischenraum wird durch spezielles Trockenmittel möglichst trocken gehalten. Das ist notwendig, damit bei Temperaturwechsel, insbesondere wenn die Außenscheibe abkühlt, keine Kondensation auf der Innenseite stattfindet. Um den Scheibenzwischenraum einerseits drucktechnisch zu öffnen, aber andererseits dennoch die Gefahr der Kondensatbildung zu verhindern wird folgender Aufbau vorgeschlagen. Die Isolierglasscheibe 1 wird als Dreifachsscheibe ausgeführt. Somit besitzt die Isolierglasscheibe zwei Scheibenzwischenräume 25, 26. Die beiden Scheibenzwischenräume 25, 26 werden durch eine dünne Einzelscheibe 22 oder auch durch eine dünne transparente Folie 22 getrennt. Der äußere Scheibenzwischenraum 25 wird wie bei einer normalen Isolierglasscheibe hermetisch verschlossen. Dieser Scheibenzwischenraum 25 wird auch relativ klein gehalten. Der innere Scheibenzwischenraum 26 wird durch ein oder mehrere Druckausgleichsrohre 27, vorzugsweise Kapillarröhrchen, mit der Außenluft verbunden. Die Außenluft ist im Regelfall immer trockener als beheizte Raumluft. Bei Temperaturerhöhung dehnt sich die Luft bzw. das Gas in den beiden Scheibenzwischenräumen 25, 26 aus. Da der äußere Scheibenzwischenraum 25 hermetisch dicht geschlossen ist erhöht sich hier der Druck. Durch den Druck baucht sich die innere Einzelscheibe 22 in Richtung des inneren Scheibenzwischenraumes 26 aus. Umso dünner die Einzelscheibe 22 umso mehr kann sich die Einzelscheibe 22 ausbauchen. Hierdurch stellt sich im äußeren Scheibenzwischenraum 25 nur eine geringe Druckerhöhung ein. Wird der äußere Scheibenzwischenraum 25 noch relativ klein gehalten, wird auch hierdurch die Druckerhöhung weiter reduziert. Der innere Scheibenzwischenraum 26 ist drucktechnisch mit der Außenluft verbunden. Das bedeutet, dass jegliche Volumenänderungen und Temperaturänderungen im inneren Scheibenzwischenraum 26 keine bzw. nur geringe Druckveränderungen zur Folge haben. Der drucktechnische Anschluss des inneren Scheibenzwischenraumes 26 sollte nur an die Außenluft erfolgen. Da bei Volumenänderungen zwangsweise Außenluft auch nach innen in den Scheibenzwischenraum 26 geführt wird, wird auch zwangsweise Feuchtigkeit mit eingetragen. Ein Teil der Feuchtigkeit wird durch das Trockenmittel 10 absorbiert. Ist das Trockenmittel 10 gesättigt wird die Feuchtigkeit von der im Scheibenzwischenraum 25, 26 vorhandenen Luft aufgenommen. Aufgrund der vorher beschriebenen Ausführung besteht keine Gefahr der Kondensatbildung.With normal insulating glass, the space between the panes is intentionally hermetically sealed. The air or the gas in the space between the panes is kept as dry as possible by means of a special desiccant. This is necessary so that when the temperature changes, especially when the outer pane cools, no condensation takes place on the inside. In order to open the interpane space on the one hand by means of printing technology, but on the other hand nevertheless to prevent the risk of condensate formation, the following structure is proposed. The insulating glass pane 1 is designed as a triple disc. Thus, the insulating glass has two disc spaces 25, 26. The two disc spaces 25, 26 are by a thin single disc 22 or also separated by a thin transparent film 22. The outer space between the panes 25 is hermetically sealed as in a normal insulating glass pane. This disc space 25 is also kept relatively small. The inner space between the panes 26 is connected to the outside air by one or more pressure equalizing tubes 27, preferably capillary tubes. The outside air is usually always drier than heated room air. When the temperature increases, the air or the gas expands in the two interpane spaces 25, 26. Since the outer space between the panes 25 is hermetically sealed, the pressure increases here. Due to the pressure, the inner single disc 22 bulges in the direction of the inner space between the panes. The thinner the individual disk 22, the more the individual disk 22 can bulge. As a result, only a slight increase in pressure occurs in the outer pane space 25. If the outer pane intermediate space 25 is still kept relatively small, the pressure increase is also further reduced as a result. The inner space between the panes 26 is connected by pressure to the outside air. This means that any volume changes and temperature changes in the inner space between the panes 26 result in no or only slight pressure changes. The printing technical connection of the inner space between the panes 26 should only be made to the outside air. As volume changes forcibly outside air is also conducted inwardly into the space between the panes 26, moisture is also forced to be registered. Part of the moisture is absorbed by the desiccant 10. When the desiccant 10 is saturated, the moisture is absorbed by the air present in the space between the panes 25, 26. Due to the previously described embodiment, there is no risk of condensation.

Die von der Außenatmosphäre in den Scheibenzwischenraum 26 gelangende Außenluft ist meist trockener als die Raumluft. Zudem wird die Außertluft, wenn sie in den Scheibenzwischenraum 26 gelangt, in diesem erwärmt. Durch die Erwärmung sinkt die relative Luftfeuchtigkeit dieser Luft. Die an den inneren Scheibenzwischenraum 26 anschließenden Glaswände sind relativ warm, da sie zum einen direkt an den Innenraum anschließen, oder durch den äußeren Scheibenzwischenraum 25 von der Außenseite isoliert sind. Insofern besteht auch bei Vorhandensein von Feuchtigkeit im innern Scheibenzwischenraum 26 keine Gefahr der Kondensatbildung.The outside air entering the space between the panes of the outside atmosphere 26 is usually drier than the room air. In addition, the outward air, when it enters the space between the panes 26, is heated therein. Heating reduces the relative humidity of this air. The adjoining the inner space between the panes 26 glass walls are relatively warm, as they connect directly to the interior, or isolated by the outer pane space 25 from the outside. Insofar, there is also in the presence of moisture in the inner space between the panes 26 no risk of condensation.

In einer weiteren, in Figur 3 angezeigten Ausgestaltung, können zwischen dem Abstandsprofil 5, bzw. zwischen den Profilteilen 5a, 5b (nicht gezeigt), und den Außenscheiben 2, 3 aus optischen Gründen noch zusätzliche Profile 19 eingefügt werden. Dies ist dann der Fall, wenn mit transparenten Klebern gearbeitet wird und die Außenscheiben 2, 3 im Bereich des Randverbundes 4 keine Bedruckung aufweisen. Hier wird dann das Abstandsprofil 5, bzw. werden die Profilteile 5a, 5b, durch die Außenscheiben 2, 3 hindurch sichtbar.In another, in FIG. 3 displayed embodiment, additional profiles 19 can be inserted between the spacer profile 5, or between the profile parts 5a, 5b (not shown), and the outer plates 2, 3 for reasons of appearance. This is the case when working with transparent adhesives and the outer disks 2, 3 in the region of the edge composite 4 have no printing. Here is the distance profile 5, or the profile parts 5a, 5b, through the outer plates 2, 3 visible through.

Für verschiedene Anwendungen wäre es jedoch wünschenswert, wenn der sichtbare Bereich des Randverbundes 4 auch in unterschiedlichen Farben oder Strukturen ausgeführt werden könnte. Dies wird folgendermaßen ausgeführt:For different applications, however, it would be desirable if the visible region of the edge bond 4 could also be made in different colors or structures. This is done as follows:

Zwischen dem Abstandsprofil 5, bzw. den Profilteilen 5a, 5b, und den Außenscheiben 2, 3 wird das zusätzliche flache Profil 19 mittels eines transparenten Klebers 20 aufgeklebt. Das Profil 19 kann mit einer oder mehreren Umkantungen ausgeführt sein. Dadurch werden die Optik und die Handhabung des Profils 19 verbessert. Das Profil 19 kann aus verschiedenen Materialien hergestellt sein, oder es kann in allen erdenklichen Farben ausgeführt werden. Durch den transparenten Kleber 20 ist das Material bzw. dessen Farbe durch die Außenscheiben 2, 3 hindurch sichtbar. Der transparente Kleber 20 des zusätzlichen Profils 19 an den Außenscheiben 2, 3 kann als transparenter UV- oder zwei-komponentiger Kleber ausgeführt sein. Die Dicke des zusätzlichen Profils 19 wird in Abhängigkeit des verwendeten Materials so gewählt, dass die auftretenden Spannungen aufgrund von unterschiedlichen Wärmedehnungen möglichst gering sind und durch die Verklebung aufgenommen werden können.Between the spacer profile 5, or the profile parts 5a, 5b, and the outer plates 2, 3, the additional flat profile 19 is glued by means of a transparent adhesive 20. The profile 19 can be designed with one or more folded edges. As a result, the appearance and the handling of the profile 19 are improved. The profile 19 can be made of different materials or it can be made in any imaginable color. Through the transparent adhesive 20, the material or its color through the outer plates 2, 3 is visible. The transparent adhesive 20 of the additional profile 19 on the outer panes 2, 3 can be designed as a transparent UV or two-component adhesive. The thickness of the additional profile 19 is chosen as a function of the material used so that the stresses occurring due to different thermal expansion are as small as possible and can be absorbed by the bond.

Eine weitere Ausführungsform zeigt Figur 4. Eine Isolierglasscheibe 1b weist zwei Außenscheiben 2, 3 auf, wobei in einem von den beiden Außenscheiben 2, 3 begrenzten Zwischenraum mindestens eine weitere Scheibe oder eine Folie 22, 32, zum Ausbilden eines ersten und zweiten Scheibenzwischenraumes 30, 31 angeordnet ist. Die weitere Scheibe oder Folie 22, 32 ist zumindest bereichsweise flexibel ausgebildet. Ein Abstandsprofil 5, welches zwischen den beiden Außenscheiben 2, 3 angeordnet ist, weist einen ersten Bereich 26 und einen zweiten Bereich 27 auf, welche miteinander bereichsweise schubfest verbindbar oder verbunden sind. Der erste Bereich 26 und der zweite Bereich 27 des Abstandsprofils 5 sind jeweils als Abstandsprofilelemente mit einer L-förmigen Querschnittsgeometrie ausgebildet._Jeder der Abstandprofilelemente weist zwei Schenkel 26a, 26b; 27a, 27b auf. In dem Verbindungsbereich der beiden Schenkel 26a, 26b; 27a, 27b eines jeden Abstandsprofilelements ist jeweils ein gelenkiger Bereich 13 gebildet. Ein erster Schenkel 26a, 27a eines jeden Bereichs 26, 27 verläuft parallel zu einer der beiden Außenscheiben 2, 3 und ist mit der Außenscheibe 2, 3 schubfest verbunden. Ein zweiter Schenkel 26b des einen Bereichs 26 verläuft parallel zu einem zweiten Schenkel 27b des anderen Bereichs 27 und ist mit diesem zumindest in einem Bereich 28 verbunden. Ein Druckausgleich ist zumindest für einen der beiden Scheibenzwischenräume 30, 31 vorgesehen, wobei mindestens ein Druckausgleichsröhrchen 29, insbesondere Kapillarröhrchen vorgesehen ist, und/oder wobei mindestens eine Membran, insbesondere eine luftaber nicht wasserdurchlässige Membran, in einem Kanal 29 vorgesehen ist, zum Zwecke eines Druckausgleiches einen Scheibenzwischenraum mit der Außenatmosphäre verbindet. Ferner kann ein oder mehrere Trockenmittel 10 in einem oder mehreren Hohlräumen in den Scheibenzwischenräumen 30, 31 integriert sein und über Klebepunkte 33 gehalten werden. Des weiterem kann das Trockenmittel 10 auch in einem Trockenmittelprofil 9 gehalten werden.Another embodiment shows FIG. 4 , An insulating glass pane 1b has two outer panes 2, 3, wherein in a space bounded by the two outer panes 2, 3, at least one further pane or foil 22, 32, for forming a first and second pane intermediate space 30, 31 is arranged.

Each of the spacer profile elements has two legs 26a, 26b; 27a, 27b. In the connection region of the two legs 26a, 26b; 27a, 27b of each spacer profile element, an articulated region 13 is formed in each case. A first leg 26a, 27a of each region 26, 27 runs parallel to one of the two outer disks 2, 3 and is connected to the outer disk 2, 3 in a shear-resistant manner. A second leg 26b of the one region 26 runs parallel to a second leg 27b of the other region 27 and is connected thereto at least in one region 28. A pressure compensation is provided at least for one of the two disc spaces 30, 31, wherein at least one pressure equalization tube 29, in particular capillary tube is provided, and / or at least one membrane, in particular a luftaber not permeable membrane, is provided in a channel 29, for the purpose of Pressure equalization joins a disc space with the outside atmosphere.
