Abstract

A framed planar load-bearing element (3) has a profile frame (2) peripherally surrounding it. A peripheral edge portion (6) of the planar load-bearing element (3) is received in a receiving portion (7). The edge portion (6) is peripherally spaced apart from bounding walls (11 to 13) of the receiving portion (7) both parallel and perpendicular to a load-bearing element plane (14) pre-defined by the planar load-bearing element (3). Consequently, a peripheral receiving chamber (15) is formed between the edge portion (6) and the bounding walls (11 to 13) of the profile frame (2). Arranged opposite one another on both sides of the load-bearing element plane (14) are sealing profiles (16, 17) which seal visible sides (18, 19) of the profile frame (2) with respect to the edge portion (6). Arranged separately to the sealing profiles (16, 17) is a peripherally bearing sealing element (21) made of a material which is soft as compared with a frame profile (1) of the profile frame (2). The sealing element (21) seals at least one of the bounding walls (12) peripherally with respect to the planar load-bearing element (3). The receiving chamber (5) is thus divided into at least two chamber portions (27, 28) in a plane of separation (26) which extends parallel to the load-bearing element plane (14). A thickness (S) of the sealing element (21) at the point where said element separates the chamber portions (27, 28) from one another is less than half as much as a thickness (D) of the edge portion (6) of the planar load-bearing element (3) perpendicular to the load-bearing element plane (14). The result is a framed planar load-bearing element whose heat-insulating effect is improved by virtue of the convection-inhibiting sealing element.

Description

Gerahmtes Flächenelement sowie Rahmenprofil für ein derartiges gerahmtes Flächentragelement Framed surface element and frame profile for such a framed surface support element
Die Erfindung betrifft ein gerahmtes Flächentragelement nach dem Oberbegriff des Anspruches 1. Ferner betrifft die Erfindung ein Rahmenprofil für ein derartiges gerahmtes Flächentragelement.The invention relates to a framed surface support element according to the preamble of claim 1. Furthermore, the invention relates to a frame profile for such a framed surface support element.
Ein gerahmtes Flächentragelement der eingangs genannten Art ist bekannt aus der DE 103 20 830 A1. Dieses gerahmte Flächentragelement hat sich in der Praxis gut bewährt. Gleichwohl besteht ständig ein Bedarf, die wärmeisolierenden Eigenschaften eines derartigen Flächentragelements weiter zu verbessern.A framed surface support element of the type mentioned is known from DE 103 20 830 A1. This framed surface support element has proven itself in practice well. Nevertheless, there is a constant need to further improve the heat-insulating properties of such a surface support member.
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein gerahmtes Flächentragelement der eingangs genannten Art derart weiter zu bilden, dass dessen wärmeisolierende Wirkung verbessert ist.It is therefore an object of the present invention to further develop a framed surface support member of the type mentioned above, that its heat-insulating effect is improved.
Diese Aufgabe ist erfindungsgemäß gelöst durch ein gerahmtes Flächentragelement mit den im Kennzeichnungsteil des Anspruchs 1 angegebenen Merkmalen.This object is achieved by a framed surface support element with the features specified in the characterizing part of claim 1.
Erfindungsgemäß wurde erkannt, dass die Luftkonvektion in der Aufnahmekammer einen wesentlichen Beitrag zum Wärmeübergang zwischen der Außen- und der Innenseite des gerahmten Flächentragelements liefert. Benachbart zum äußeren Dichtprofil liegt in der Aufnahmekammer relativ kalte Luft vor. Diese strömt bei den bisher bekannten gerahmten Flächentragelementen durch Konvektion in die dem inneren Dichtprofil benachbarten Bereiche der Aufnahmekammer. Zentrierelemente, wie sie beispielsweise aus der DE 20 2005 001 073 U1 bekannt sind, vermögen diese Konvektion nicht wirksam zu unterbinden, da sie keine sichere und dichtende Unterteilung der Aufnahmekammer gewährleisten. Aus dem Stand der Technik sind auch gerahmte Flächentragelemente mit voll umlaufender Verklebung bekannt. Eine derartige voll umlaufende Verklebung stellt jedoch eine Wärmebrücke dar, die nicht toleriert werden kann. Schließlich sind von den Dichtprofilen, die den Randabschnitt des Flächentragelements zu den seitlichen Begrenzungswänden am Übergang zu den Sichtseiten des Profilrahmens abdichten, ausgehende Begrenzungsabschnitte zur Begrenzung einer eingebrachten Kleberaupe bekannt. Als Beispiel hierfür sei die DE 20 2005 009 450 IM genannt. Diese bekannten, an den den Sichtseiten-Übergängen zugeordneten Dichtprofilen angeformten Kleberaupen-Begrenzungen sind zur nennenswerten Unterbindung einer Konvektion in der Aufnahmekammer, wie erfindungsgemäß erkannt wurde, nicht geeignet, da, sofern durch die bekannten Kleberaupen-Begrenzungen überhaupt eine Unterteilung der Aufnahmekammer in gegeneinander abgedichtete Kammerabschnitte erfolgt, ein Kammerabschnitt verbleibt, dessen Volumen praktisch so groß ist wie das Gesamtvolumen der Aufnahmekammer.According to the invention it has been recognized that the air convection in the receiving chamber provides a significant contribution to the heat transfer between the outside and the inside of the framed surface support element. Adjacent to the outer sealing profile, relatively cold air is present in the receiving chamber. This flows in the previously known framed surface support elements by convection in the adjacent the inner sealing profile areas of the receiving chamber. Centering elements, as they are known for example from DE 20 2005 001 073 U1, are not able to effectively prevent this convection, since they do not ensure a secure and sealing subdivision of the receiving chamber. Framed surface support elements with fully encircling bonding are also known from the prior art. However, such a fully circumferential bond is a thermal bridge that can not be tolerated. Finally, out of the sealing profiles that seal the edge portion of the surface support member to the lateral boundary walls at the transition to the visible sides of the profile frame, outgoing boundary sections for limiting an introduced Kleberaupe. An example of this is DE 20 2005 009 450 IM. These known, at the visual side transitions associated sealing profiles formed Kleberaupen-limits are for significant suppression of convection in the receiving chamber, as inventively recognized, not suitable because, if at all by the known Kleberaupen limitations a subdivision of the receiving chamber sealed against each other Chamber sections takes place, a chamber portion remains whose volume is practically as large as the total volume of the receiving chamber.
Durch das erfindungsgemäße Dichtelement wird die Aufnahmekammer in zwei Kammerabschnitte unterteilt, wobei einer der Kammerabschnitte der Außenseite und der andere der beiden Kammerabschnitte der Innenseite des Profilrahmens zugeordnet ist. In diesen beiden Kammerabschnitten hat die hierin enthaltene Luft jeweils eine relativ homogene Temperatur. In den einzelnen Kammerabschnitten findet daher, falls überhaupt, nur eine gerin- ' ge Konvektion statt. Zwischen den Kammerabschnitten ist die Konvektion aufgrund des Dichtelements unterbunden. Ein nennenswerter Wärmeübergang zwischen der Außen- und der Innenseite des Profilrahmens aufgrund von Konvektion wird durch das Dichtelement daher wirkungsvoll verhindert. Wie Messungen der Anmelderin ergeben haben, führt das Dichtelement zu einer erheblichen Verringerung des Wärmeübergangskoeffizienten des gesamten gerahmten Flächentragelements. Die Wärmeisolierung durch das gerahmte Flä- chentragelement ist daher durch den Einsatz des erfindungsgemäßen Dichtelements deutlich verbessert. Das erfindungsgemäße Verhältnis zwischen der Stärke des Dichtelements und der Dicke des Randabschnitts gewährleistet dabei, dass kein nennenswerter Wärmeübergang durch das Dichtelement selbst erfolgt. Luft in der Aufnahmekammer, die an sich einen guten Wärmeisolator darstellt, wird durch das Dichtelement nur unwesentlich verdrängt. Damit die Konvektionshemmung durch das Dichtelement besonders wirksam ist, sollten die nach der Unterteilung durch das Dichtelement vorliegenden Kammerabschnitte bevorzugt in ihrer Größe vergleichbare Volumina aufweisen.By the sealing element according to the invention, the receiving chamber is divided into two chamber sections, wherein one of the chamber sections of the outside and the other of the two chamber sections is assigned to the inside of the profile frame. In each of these two chamber sections, the air contained therein has a relatively homogeneous temperature. Therefore, in the individual chamber sections, if at all, only a slight convection takes place. Between the chamber sections, the convection is prevented due to the sealing element. A significant heat transfer between the outer and the inside of the profile frame due to convection is therefore effectively prevented by the sealing element. As measurements by the Applicant have shown, the sealing element leads to a considerable reduction in the heat transfer coefficient of the entire framed surface support element. The thermal insulation by the framed surface support element is therefore significantly improved by the use of the sealing element according to the invention. The ratio according to the invention between the thickness of the sealing element and the thickness of the edge section ensures that there is no appreciable heat transfer through the sealing element itself. Air in the receiving chamber, which is a good heat insulator per se, is displaced only insignificantly by the sealing element. In order for the convection inhibition by the sealing element to be particularly effective, the chamber sections present after the subdivision by the sealing element should preferably have comparable volumes in size.
Ein Verhältnis der Erstreckung der Kammerabschnitte zur Stärke des Dichtelements nach Anspruch 2 stellt sicher, dass mindestens zwei Kammerabschnitte mit einem nennenswerten Volumenanteil an der gesamten Aufnahmekammer vorliegen. Aufgrund dieser Unterteilung ist kein Kammerabschnitt so groß, dass in diesem ein Wärmeübergang durch Konvektion in vergleichbarem Umfang wie in der gesamten Aufnahmekammer ohne unterteilendes Dichtelement stattfindet.A ratio of the extent of the chamber sections to the thickness of the sealing element according to claim 2 ensures that at least two chamber sections are present with a significant volume fraction of the entire receiving chamber. Due to this subdivision, no chamber section is so large that heat transfer by convection takes place in a comparable extent as in the entire receiving chamber without subdividing sealing element.
Eine Fixierung des Dichtelements nach Anspruch 3 ist unaufwändig. Alternativ kann das Dichtelement auch an einer der Begrenzungswände des Aufnahmeabschnitts z. B. durch Koextrusion einstückig angeformt sein.A fixation of the sealing element according to claim 3 is inexpensive. Alternatively, the sealing element on one of the boundary walls of the receiving portion z. B. integrally formed by coextrusion.
Eine Dichtlippe nach Anspruch 4 gewährleistet eine sichere Abdichtung, ohne dass es auf eine zu exakte Relativpositionierung des Flächentragelements zum Rahmenprofil ankommt. Die Dichtlippe kann im Querschnitt einen gebogenen oder schrägen Verlauf haben.A sealing lip according to claim 4 ensures a secure seal, without the need for an exact relative positioning of the surface support member to the frame profile. The sealing lip may have a curved or oblique profile in cross section.
Eine Kompressions-Schlauchdichtung nach Anspruch 5 kann besonders günstig hergestellt werden und ist in ihrer Positionierung flexibel.A compression hose seal according to claim 5 can be made particularly favorable and is flexible in their positioning.
Einzel-Dichtelemente nach Anspruch 6 können so angeordnet sein, dass der größte zusammenhängende Kammerabschnitt im Vergleich zur gesamten Aufnahmekammer ein recht geringes Volumen hat, zum Beispiel ein Volumen, welches weniger als halb so groß ist als das Gesamtvolumen der Aufnahmekammer. Hierdurch kann ein Wärmeübergang durch Konvektion besonders wirkungsvoll unterbunden werden.Individual sealing elements according to claim 6 may be arranged so that the largest contiguous chamber section compared to the entire receiving chamber has a fairly small volume, for example, a volume which is less than half as large as the total volume of the receiving chamber. As a result, a heat transfer can be prevented by convection particularly effective.
Ein Dichtelement nach Anspruch 7 ermöglicht die Verwendung von im Vergleich zum Stand der Technik unveränderten Rahmenprofilen, da das Dichtelement nicht am Rahmenprofil, sondern am Flächentragelement fixiert ist.A sealing element according to claim 7 allows the use of unchanged compared to the prior art frame profiles, since the sealing element is not fixed to the frame profile, but on the surface support member.
Eine Ausführung des Dichtelements nach Anspruch 8 hat sich zur Erzielung einer sicheren dichtenden Unterteilung der Aufnahmekammer als besonders geeignet herausgestellt.An embodiment of the sealing element according to claim 8 has been found to achieve a secure sealing subdivision of the receiving chamber to be particularly suitable.
Auch ein Dichtelement nach Anspruch 9 gewährleistet eine sichere dichtende Unterteilung der Aufnahmekammer in Kammerabschnitte.A sealing element according to claim 9 ensures a secure sealing subdivision of the receiving chamber in chamber sections.
Die Vorteile des Anspruchs 10 entsprechen denen, die oben im Zusammenhang mit dem Anspruch 7 erwähnt wurden. Der Aufnahmerahmen kann als Aufsatz auf ein herkömmliches Flächentragelement ausgebildet sein, so dass das erfindungsgemäße Dichtelement einsetzbar ist, ohne dass am Flächentragelement einerseits oder am Rahmenprofil andererseits Veränderungen vorgenommen werden müssen. Hierdurch können bestehende gerahmte Flächentragelemente zu erfindungsgemäßen gerahmten Flächentragelementen mit relativ geringem Aufwand umgerüstet werden.The advantages of claim 10 correspond to those mentioned above in connection with claim 7. The receiving frame can be designed as an attachment to a conventional surface support element, so that the sealing element according to the invention can be used without changes must be made to the surface support element on the one hand or the frame profile on the other hand. As a result, existing framed surface support elements can be converted to framed surface support elements according to the invention with relatively little effort.
Eine Anordnung des Dichtelements nach Anspruch 11 gewährleistet eine Unterteilung der Aufnahmekammer in zwei vergleichbar große Kammerabschnitte. Alternativ ist es möglich, das Dichtelement auch an seitlichen Begrenzungswänden der Aufnahmekammer anzuordnen. Hierbei muss allerdings gewährleistet sein, dass die Aufteilung in Kammerabschnitte derart ist, dass im größten verbleibenden Kammerabschnitt kein nennenswerter Wärmeübergang durch Konvektion erfolgt.An arrangement of the sealing element according to claim 11 ensures a subdivision of the receiving chamber into two comparably large chamber sections. Alternatively, it is possible to arrange the sealing element also on lateral boundary walls of the receiving chamber. In this case, however, it must be ensured that the division into chamber sections is such that no appreciable heat transfer by convection takes place in the largest remaining chamber section.
Mindestens ein Trag- und Positionierklotz nach Anspruch 12 gewährleistet eine gleichmäßige statische Kraftüberleitung vom Flächentragelement auf den Profilrahmen, wobei gleichzeitig eine sichere Abdichtung der Kammerabschnitte der Aufnahmekammer gegeneinander auch am Ort des mindestens einen Trag- und Positionierklotzes gewährleistet ist. Die Aussparung im mindestens einen Trag- und Positionierklotz kann zudem sicherstellen, dass das Dichtelement am Ort des mindestens einen Trag- und Positionierklotzes nicht übermäßig verformt wird.At least one supporting and positioning block according to claim 12 ensures a uniform static force transmission from the surface support member on the profile frame, at the same time a secure sealing of the chamber sections of the receiving chamber is ensured against each other also at the location of at least one supporting and positioning block. The recess in the at least one supporting and positioning block can also ensure that the sealing element is not excessively deformed at the location of the at least one supporting and positioning block.
Eine weitere Aufgabe der Erfindung ist es, ein Rahmenprofil für ein erfindungsgemäßes Flächentragelement anzugeben.Another object of the invention is to provide a frame profile for a surface support element according to the invention.
Diese Aufgabe ist erfindungsgemäß gelöst durch die Rahmenprofile mit den im Kennzeichnungsteil des Anspruchs 13 und alternativ im Kennzeichnungsteil des Anspruchs 14 angegebenen Merkmalen.This object is achieved by the frame profiles with the features specified in the characterizing part of claim 13 and, alternatively, in the characterizing part of claim 14.
Die Vorteile derartiger Rahmenprofile entsprechen denjenigen, die oben im Zusammenhang mit den Vorteilen des gerahmten Flächentragelements angegeben wurden.The advantages of such frame profiles are similar to those given above in connection with the advantages of the framed panel member.

Ein in Fig. 1 gebrochen im Querschnitt dargestelltes Rahmenprofil 1 ist Teil eines in Fig. 10 dargestellten Profilrahmens 2 für ein Flächentragelement 3 in Form einer Isolierverglasung mit zwei miteinander verbundenen Glasscheiben 4, 5, die im Schnitt zum Beispiel in Fig. 2 dargestellt ist. Die Verbindung der Glasscheiben 4, 5 erfolgt randseitig über ein Verbin- dungs-Profilelement 5a. Bei der in der Fig. 2 linken Glasscheibe 4 handelt es sich um die bei montiertem gerahmtem Flächentragelement äußere Scheibe und bei der Glasscheibe 5 um die innere Scheibe. Das Rahmenprofil 1 weist eine Mehrzahl von Hohlkammern auf, die in der Zeichnung nur ausschnittsweise sichtbar sind.A broken in Fig. 1 in cross-section frame profile 1 is part of a profiled frame 2 shown in Fig. 10 for a surface supporting element 3 in the form of insulating glass with two interconnected glass sheets 4, 5, which is shown in section, for example in Fig. 2. The connection of the glass panes 4, 5 takes place at the edge via a connecting profile element 5a. In the left in Fig. 2, the glass pane 4 is the outer pane mounted on the framed surface support element and the inner pane of the glass pane 5. The frame profile 1 has a plurality of hollow chambers, which are only partially visible in the drawing.
Der Profilrahmen 2 läuft stirnseitig um das Flächentragelement 3 um. Ein umlaufender Randabschnitt 6 des Flächentragelements 3 wird von einem Aufnahmeabschnitt 7 des Profilrahmens 2 aufgenommen, der auch als Glasfalz bezeichnet wird. Der Aufnahmeabschnitt 7 wird gebildet einerseits vom Rahmenprofil 1 und andererseits von einer Leiste 8, die auch als Glasleiste bezeichnet wird, und mit einem Steg 9 in eine Rastaufnahme 10 des Rahmenprofils 1 eingerastet ist. Das Rahmenprofil 1 und die Leiste 8 sind Extrusionsprofile.The profile frame 2 runs frontally around the surface support member 3. A peripheral edge portion 6 of the surface support member 3 is received by a receiving portion 7 of the profile frame 2, which is also referred to as a glass fold. The receiving portion 7 is formed on the one hand by the frame profile 1 and on the other hand by a strip 8, which is also referred to as a glass strip, and is engaged with a web 9 in a locking receptacle 10 of the frame profile 1. The frame profile 1 and the bar 8 are extrusion profiles.
Der Randabschnitt 6 des Flächentragelements 3 ist von Begrenzungswänden 11, 12, 13 des Aufnahmeabschnitts 7 parallel und senkrecht zu einer vom Flächentragelement 3 vorgegebenen Tragelementebene 14, die mittig zwischen den Glasscheiben 4, 5 liegt, umlaufend beabstandet. Hierdurch ist eine umlaufende und im Querschnitt im wesentlichen U-förmige Aufnahmekammer 15 zwischen dem Randabschnitt 6 und den Begrenzungswänden 11 bis 13 des Profilrahmens 2 gebildet. Die Begrenzungswand 11 bildet den in Fig. 2 linken Schenkel, die Begrenzungswand 12 den unteren Schenkel und die Begrenzungswand 13 den eine Stufe enthaltenden rechten Schenkel der äußeren Begrenzung dieser U-Form.The edge portion 6 of the surface support member 3 is of peripheral walls 11, 12, 13 of the receiving portion 7 parallel and perpendicular to a predetermined by the surface support member 3 support element level 14, which is centrally between the glass sheets 4, 5 circumferentially spaced. As a result, a circumferential and in cross-section substantially U-shaped receiving chamber 15 between the edge portion 6 and the boundary walls 11 to 13 of the profile frame 2 is formed. The boundary wall 11 forms the left in Fig. 2 leg, the boundary wall 12, the lower leg and the boundary wall 13 which contains a stage right leg of the outer boundary of this U-shape.
Beiderseits der Tragelementebene 14 sind einander gegenüberliegend Dichtprofile 16, 17 vorgesehen. Diese dichten den Randabschnitt 6 des Flächentragelements 3 zu den seitlichen Begrenzungswänden 11 , 13 am Übergang zwischen diesen und äußeren und inneren Sichtseiten 18, 19 des Profilrahmens 2 ab.On both sides of the support element level 14 sealing profiles 16, 17 are provided opposite each other. These seal the edge portion 6 of the surface support element 3 to the lateral boundary walls 11, 13 at the transition between these and outer and inner visible sides 18, 19 of the profile frame 2 from.
Das Dichtprofil 16 liegt über drei zueinander parallele Auflageabschnitte an der äußeren Glasscheibe 4 an und ist formschlüssig in einen Aufnahmeabschnitt 20 des Rahmenprofils 1 eingerastet. Das Dichtprofil 16 dient insbesondere dazu, das Rahmenprofil 1 schlagregendicht gegen das Flächentragelement 3 abzudichten.The sealing profile 16 abuts against the outer glass pane 4 via three mutually parallel support sections and is positively locked in a receiving section 20 of the frame profile 1. The sealing profile 16 is used in particular to seal the frame profile 1 against rainfall impact against the surface support element 3.
Das Dichtprofil 17 ist durch zwei übereinander an der inneren Glasscheibe 5 anliegende Dichtlippen gebildet. Die Dichtlippen sind an der Leiste 8 anextrudiert, nämlich durch Koextrusion in 2-K-Technik angeformt.The sealing profile 17 is formed by two superimposed on the inner glass pane 5 sealing lips. The sealing lips are extruded on the strip 8, namely formed by coextrusion in 2-K technique.
Von den Dichtprofilen 16, 17 separat ist ein Dichtelement 21 , welches am Randabschnitt 6 des Flächentragelements 3 umlaufend anliegt. Das Dichtelement 21 ist aus einem im Vergleich zum Rahmenprofil 1 weichen und elastischen Material. Ein Fuß 22 des Dichtelements 21 ist formschlüssig in einer Aufnahmenut 23 fixiert. Letztere ist einstückig an der unteren Begrenzungswand 12 des Aufnahmeabschnitts 7 angeformt. Die Aufnahmenut 23 kann, wie in Fig. 1 dargestellt, in der unteren Begrenzungswand 12 versenkt oder auf dieser aufgesetzt, wie in Fig. 2 dargestellt, ausgebildet sein. Das Dichtelement 21 hat eine im Querschnitt gebogene und elastische freie Dichtlippe 24, die in einer zum Beispiel in den Fig. 2 und 3 dargestellten Dichtposition, über eine seitliche Lippenwand 25 dichtend am Flächentragelement 3 im Bereich des Verbindungs-Profilelements 5a anliegt.Of the sealing profiles 16, 17 separately is a sealing element 21, which rests circumferentially on the edge portion 6 of the surface support member 3. The sealing element 21 is made of a soft and elastic material compared to the frame profile 1. A foot 22 of the sealing element 21 is positively fixed in a receiving groove 23. The latter is integrally formed on the lower boundary wall 12 of the receiving portion 7. The receiving groove 23 can, as shown in Fig. 1, sunk in the lower boundary wall 12 or placed on this, as shown in Fig. 2, be formed. The sealing element 21 has a cross-sectionally curved and elastic free sealing lip 24, which rests sealingly on the surface support element 3 in the region of the connecting profile element 5a via a lateral lip wall 25 in a sealing position, for example, in FIGS. 2 and 3.
Alternativ kann die Dichtlippe 24 im Querschnitt keinen gebogenen, sondern einen schrägen Verlauf aufweisen. Das Dichtelement 21 dichtet die untere Begrenzungswand 12 umlaufend gegen das Flä- chentragelement 3 ab. Auf diese Weise wird die Aufnahmekammer 15 in einer Trennebene 26, die parallel zur Tragelementebene 14 verläuft, in zwei Kammerabschnitte 27, 28 unterteilt.Alternatively, the sealing lip 24 in cross-section not curved, but have an oblique course. The sealing element 21 seals the lower boundary wall 12 circumferentially against the surface carrying element 3. In this way, the receiving chamber 15 in a parting plane 26 which is parallel to the support element plane 14, divided into two chamber sections 27, 28.
Eine Stärke S (vgl. Fig. 1) des Dichtelements 21 ist dort, wo das Dichtelement 21 die Kammerabschnitte 27, 28 voneinander trennt, weniger als halb so groß wie eine Dicke D des Randabschnitts 6 des Flächentragelements 3 senkrecht zur Trennelementebene 14. Bei der Ausführung des Dichtelements 21 nach den Fig. 1 bis 3 ist die Stärke S sogar weniger als ein Zehntel der Dicke D. Das Dichtelement 21 ist daher als Wärmebrücke zwischen den Kammerabschnitten 27 und 28 vernachlässigbar.A thickness S (see Fig. 1) of the sealing element 21 is where the sealing element 21, the chamber sections 27, 28 separated from each other, less than half as large as a thickness D of the edge portion 6 of the surface support member 3 perpendicular to the separating element level 14. In the Embodiment of the sealing element 21 according to FIGS. 1 to 3, the thickness S even less than one-tenth of the thickness D. The sealing element 21 is therefore negligible as a thermal bridge between the chamber sections 27 and 28.
Die Unterteilung der Aufnahmekammer 15 durch das Dichtelement 21 ist asymmetrisch. Der dem Dichtprofil 16 benachbarte, äußere Kammerabschnitt 27 ist kleiner als der dem Dichtprofil 17 benachbarte innere Kammerabschnitt 28. Die Erstreckung der Kammerabschnitte 27, 28 senkrecht zur Tragelementebene 14 ist mehr als doppelt so groß, im dargestellten Ausführungsbeispiel sogar mehr als zehnmal so groß, wie die Stärke S des Dichtelements 21. Hierdurch ist sichergestellt, dass keiner der Kammerabschnitte 27, 28 nach der Unterteilung so groß ist, dass durch das Dichtelement die Konvektionsverhältnisse in der Aufnahmekammer 15 nicht nennenswert beeinflusst werden.The subdivision of the receiving chamber 15 through the sealing element 21 is asymmetrical. The outer chamber portion 27 adjacent to the sealing profile 16 is smaller than the inner chamber portion 28 adjacent to the sealing profile 17. The extent of the chamber portions 27, 28 perpendicular to the support element plane 14 is more than twice as large, in the illustrated embodiment even more than ten times as large This ensures that none of the chamber sections 27, 28 after the subdivision is so large that the convection conditions in the receiving chamber 15 are not appreciably influenced by the sealing element.
Ein Vergleich der Fig. 2 und 3 mit der Fig. 1 zeigt, dass das Dichtelement 21 in der Dichtposition verglichen mit einer in Fig. 1 dargestellten freien Position im Bereich der Dichtlippe 24 stärker umgebogen und damit gegen das Flächentragelement 3 vorgespannt ist. Dies gewährleistet eine sichere Dichtwirkung des Dichtelements 21 und damit eine im wesentlichen gasdichte Unterteilung der Aufnahmekammer 15 in die Kammerabschnitte 27, 28.A comparison of FIGS. 2 and 3 with FIG. 1 shows that the sealing element 21 in the sealing position is bent more strongly in the region of the sealing lip 24 compared to a free position shown in FIG. 1 and is thus prestressed against the surface-supporting element 3. This ensures a secure sealing action of the sealing element 21 and thus a substantially gas-tight subdivision of the receiving chamber 15 into the chamber sections 27, 28th
Fig. 3 zeigt am Dichtelement 21 rechts angrenzend eine Klebstoffraupe 29, die zur Befestigung des Flächentragelements 3 am Profilrahmen 2 dient. Die Klebstoffraupe 29 ist in Fig. 3 nach unten begrenzt durch die Begrenzungswand 12, nach oben begrenzt durch das Flächentragelement 3 und nach links begrenzt durch das Dichtelement 21.FIG. 3 shows, on the right-hand side, sealing bead 21 on the sealing element 21, which adhesive bead 29 serves for fastening the sheet-carrying element 3 to the profiled frame 2. The adhesive bead 29 is limited in Fig. 3 down through the boundary wall 12, bounded above by the surface support member 3 and limited to the left by the sealing element 21st
Die Klebstoffraupe 29 ist nicht voll umlaufend um den Profilrahmen 2 ausgeführt, sondern, es liegt eine partielle Verklebung mit mehreren Klebstoffraupenabschnitten vor, wie diese an sich aus der DE 103 20 830 A1 bekannt ist. Fig. 10 zeigt die Verteilung der Klebstoffraupe 29 im Profilrahmen 2. Die Klebstoffraupe 29 ist in vier Abschnitten aufgetragen, wobei jeweils ein Klebstoffraupenabschnitt einer der vier Rahmenseiten des rechteckigen Profilrahmens 2 zugeordnet ist. Die Klebstoffraupenabschnitte überdecken jeweils über die Hälfte einer Seite des Profilrahmens 2, wobei sie jeweils mittig im dieser Seite zugeordneten Aufnahmeabschnitt 7 angeordnet sind.The adhesive bead 29 is not executed completely circumferentially around the profile frame 2, but instead there is a partial bonding with a plurality of adhesive bead portions, as is known per se from DE 103 20 830 A1. 10 shows the distribution of the adhesive bead 29 in the profile frame 2. The adhesive bead 29 is applied in four sections, one adhesive bead section in each case being assigned to one of the four frame sides of the rectangular profile frame 2. The adhesive bead sections each cover over half of one side of the profile frame 2, wherein they are respectively arranged centrally in the receiving section 7 assigned to this side.
Fig. 4 bis 9 zeigen weitere Ausführungsformen von Profilrahmen 2, die sich insbesondere in der Gestaltung des Dichtelements zur Unterteilung der Aufnahmekammer 15 unterscheiden. Komponenten, die denjenigen entsprechen, die vorstehend schon unter Bezugnahme auf die Fig. 1 bis 3 sowie 10 beschrieben wurden, tragen dieselben Bezugsziffern und werden nicht nochmals im Einzelnen diskutiert.4 to 9 show further embodiments of profile frame 2, which differ in particular in the design of the sealing element for dividing the receiving chamber 15. Components corresponding to those already described above with reference to Figs. 1 to 3 and 10 bear the same reference numerals and will not be discussed again in detail.
Ein Dichtelement 30 nach Fig. 4 unterscheidet sich vom Dichtelement 21 nach den Fig. 1 und 3 durch die Querschnittsform einer Dichtlippe 31. Letztere ist bei der Ausführung nach Fig. 4 derart S-förmig gebogen ausgeführt, dass die Dichtlippe 31 über einen freien Kantenabschnitt am Flächentragelement 3 anliegt.A sealing element 30 according to Fig. 4 differs from the sealing element 21 according to FIGS. 1 and 3 by the cross-sectional shape of a sealing lip 31. The latter is executed in the embodiment of FIG. 4 so bent S-shaped that the sealing lip 31 via a free edge portion rests on the surface support element 3.
Ein Dichtelement 32 nach Fig. 5 ist als Kompressions-Schlauchdichtung ausgebildet. Letzte ist zwischen der Begrenzungswand 12 und dem Flächentragelement 3 in Aufnahmeabschnitt 7 umlaufend um den Profilrahmen 2 angeordnet. In der in Fig. 5 dargestellten Dichtstellung ist das Dichtelement 32 komprimiert, so dass es einen in etwa ovalen Querschnitt hat.A sealing element 32 according to FIG. 5 is designed as a compression hose seal. Last is arranged between the boundary wall 12 and the surface support member 3 in receiving portion 7 circumferentially about the profile frame 2. In the sealing position shown in Fig. 5, the sealing element 32 is compressed so that it has an approximately oval cross-section.
Ein Dichtelement 33 nach Fig. 6 hat einen teilkreisförmigen Querschnitt. Beide Randabschnitte 34, 35 dieser Querschnittsform liegen am Flächentragelement 3 an. Zwischen den beiden Randabschnitten 34, 35 liegt das Dichtelement 33 an der Begrenzungswand 12 an. Alternativ ist es möglich, dass die Randabschnitte 34, 35 an der Begrenzungswand 12 anliegen und dass das Dichtelement 33 zwischen den Randabschnitten 34, 35 am Flächentragelement 3 anliegt. In der in Fig. 6 dargestellten Dichtstellung ist das Dichtelement 33 zwischen dem Flächentragelement 3 und der Begrenzungswand 12 vorgespannt. Ein Dichtelement 36 nach Fig. 7 umfasst mehrere Einzel-Dichtelemente 37, die hintereinander im Aufnahmeabschnitt 7 umlaufend um den Profilrahmen 2 derart angeordnet sind, dass die Aufnahmekammer 15 senkrecht zur Tragelementebene 14 in mehrere Kammerabschnitte unterteilt ist, nämlich in den Kammerabschnitten 27, 28 der Ausführung nach den Fig. 1 bis 3 entsprechende Kammerabschnitte 38, 39 und in zwischen benachbarten Einzel-Dichtelementen 37 liegende Kammerabschnitte 40. Die Erstreckung der Kammerabschnitte 38, 39 senkrecht zur Tragelementebene 14 ist auch bei der Ausführung nach Fig. 7 mehr als doppelt so groß wie die Stärke der Einzel-Dichtelemente 37 dort, wo diese die Kammerabschnitte 38 bis 40 voneinander trennen. Die Einzel-Dichtelemente 37 sind am Verbindungs-Profilelement 5a fixiert und können beispielsweise einstückig mit diesem ausgebildet sein. Die Einzel-Dichtelemente 37 haben einen in etwa klauenförmigen Querschnitt.A sealing element 33 according to FIG. 6 has a part-circular cross-section. Both edge portions 34, 35 of this cross-sectional shape are applied to the surface support member 3. Between the two edge portions 34, 35, the sealing element 33 bears against the boundary wall 12. Alternatively, it is possible that the edge portions 34, 35 abut against the boundary wall 12 and that the sealing element 33 between the edge portions 34, 35 bears against the surface support element 3. In the sealing position shown in Fig. 6, the sealing element 33 is biased between the surface support member 3 and the boundary wall 12. A sealing element 36 according to FIG. 7 comprises a plurality of individual sealing elements 37 arranged one behind the other in the receiving section 7 around the profile frame 2 in such a way that the receiving chamber 15 is subdivided perpendicular to the support element plane 14 into a plurality of chamber sections, namely in the chamber sections 27, 28 Embodiment according to FIGS. 1 to 3 corresponding chamber sections 38, 39 and lying in between adjacent individual sealing elements 37 chamber sections 40. The extension of the chamber sections 38, 39 perpendicular to the support element level 14 is also in the embodiment of FIG. 7 more than twice as large how the thickness of the individual sealing elements 37 where they separate the chamber sections 38 to 40 from each other. The individual sealing elements 37 are fixed to the connection profile element 5a and can be formed integrally therewith, for example. The individual sealing elements 37 have an approximately claw-shaped cross-section.
Ein Dichtelement 41 nach Fig. 8 umfasst mehrere, nämlich insgesamt drei nach Art der Einzel-Dichtelemente 37 nach Fig. 7 hintereinander angeordnete Einzel-Dichtelemente 42. Die Einzel-Dichtelemente 42 haben Dichtlippen 43, die wie die Dichtlippe 31 des Dichtelements 30 nach Fig. 4 S-förmig gebogen sind. Die Einzel-Dichtelemente 42 können insbesondere einstückig mit dem Rahmenprofil 1 verbunden sein, zum Beispiel mit diesem in 2- K-Technik koextrudiert sein.A sealing element 41 according to FIG. 8 comprises a plurality of, namely a total of three individual sealing elements 42 arranged in succession in the manner of the individual sealing elements 37 according to FIG. 7. The individual sealing elements 42 have sealing lips 43 which, like the sealing lip 31 of the sealing element 30 according to FIG 4 are bent in an S shape. The individual sealing elements 42 may in particular be integrally connected to the frame profile 1, for example, be coextruded with this in 2-K technique.
Ein Dichtelement 44 nach Fig. 9 ist nach Art eines der Einzel-Dichtelemente 37 der Ausführung nach Fig. 7 ausgebildet. Das Dichtelement 44 wird von einem Aufnahmerahmen 45 getragen, der das Flächentragelement 3 umlaufend umgibt und dabei dessen Stirnseite umgreift.A sealing element 44 according to FIG. 9 is designed in the manner of one of the individual sealing elements 37 of the embodiment according to FIG. 7. The sealing element 44 is supported by a receiving frame 45, which surrounds the surface supporting element 3 circumferentially and thereby engages around its end face.
Fig. 11 zeigt entsprechend Fig. 3 einen Schnitt durch das Rahmenprofil 1 auf Höhe eines Trag- und Positionierklotzes 46. Letzterer dient zur statischen Lastaufnahme des Flächen- tragelements 3 sowie zur korrekten Positionierung des Flächentragelements 3 im Profilrahmen 2. In Umfangsrichtung um den Profilrahmen 2 verteilt liegt eine Mehrzahl derartiger Trag- und Positionierklötze 46 vor, die auch als Glasklötze bezeichnet werden. Im Bereich der Trennebene 26 hat der Trag- und Positionierklotz 46 eine Aussparung 47 zur Aufnahme des Dichtelements 21. Die Aussparung 47 wird von einem sich keilförmig verjüngenden Randabschnitt 48 des Trag- und Positionierklotzes 46 begrenzt. Das Flächentragelement 3 liegt über seine ganze Breite am Trag- und Positionierklotz 46 an. Aufgrund der Keilform des Randabschnitts 48 wird die statische Last vom Trag- und Positionierklotz 46 großflächig an die Begrenzungswand 12 weitergegeben. Auf Höhe des Trag- und Positionierklotzes 46 dichtet das Dichtelement 21 über die Dichtlippe 24 gegen den Randabschnitt 48 des Trag- und Positionierklotzes 46 ab. Der Randabschnitt 48 wiederum dichtet gegen das Flächentragelement 3 ab. Die Trag- und Positionierklötze 46 sind also aus einem Material, welches eine derartige Dichtfunktion gewährleistet. FIG. 11 shows, according to FIG. 3, a section through the frame profile 1 at the level of a support and positioning block 46. The latter serves for the static load absorption of the surface support element 3 and for the correct positioning of the surface support element 3 in the profile frame 2. In the circumferential direction around the profile frame 2 distributed is a plurality of such supporting and positioning blocks 46, which are also referred to as glass blocks. In the region of the parting plane 26, the support and positioning block 46 has a recess 47 for receiving the sealing element 21. The recess 47 is delimited by a wedge-shaped tapering edge section 48 of the support and positioning block 46. The surface-supporting element 3 rests against the supporting and positioning block 46 over its entire width. Due to the wedge shape of the edge portion 48, the static load from the support and positioning block 46 is passed over a large area to the boundary wall 12. At the height of the supporting and positioning block 46, the sealing element seals 21 via the sealing lip 24 against the edge portion 48 of the supporting and positioning block 46 from.
