Description

Die vorliegende Erfindung betrifft eine Isolierleiste für ein Tragprofil, insbesondere für eine Fassade, Fenster, Schrägverglasung oder ein Lichtdach, nach dem Oberbegriff des Anspruches 1.The present invention relates to an insulating strip for a supporting profile, in particular for a facade, windows, oblique glazing or a light roof, according to the preamble of claim 1.

Die EP 2 743 421 A1 offenbart eine Fassade oder ein Lichtdach, bei dem zwischen zwei Füllungselementen ein Isoliersteg angeordnet ist. Der Isoliersteg ist aus zwei unterschiedlichen Materialien hergestellt und umfasst einen Teil aus härterem Material zur Fixierung des Isoliersteges und einen Teil aus weicherem Material, der zur Wärmeisolierung in einer Aufnahme des Teils aus härterem Material eingefügt ist. Ein solcher Isoliersteg besitzt eine relativ gute Wärmedämmung aufgrund des weicheren Materials. Allerdings ist das härtere Material, das meist aus einem Kunststoff gebildet ist, ein vergleichsweise guter Wärmeleiter, so dass Wärmeverluste über das Teil aus härterem Material entstehen. Ein Weglassen des härteren Materials ist allerdings nicht möglich, da der Isoliersteg mit ausreichender Festigkeit an einer Schraubnut eines Tragprofils fixiert werden muss.The EP 2 743 421 A1 discloses a facade or a light roof, in which an insulating web is arranged between two filling elements. The insulating bar is made of two different materials and includes a harder material part for fixing the insulating bar and a softer material part inserted for heat insulation in a receptacle of the harder material part. Such Isoliersteg has a relatively good thermal insulation due to the softer material. However, the harder material, which is usually made of a plastic, a comparatively good heat conductor, so that heat losses over the part of harder material. However, omitting the harder material is not possible, since the insulating web must be fixed with sufficient strength on a screw groove of a support profile.

Die EP 2 642 039 A1 offenbart ein Dämmelement für eine Fassadenkonstruktion, das gemäß dem Oberbegriff des Anspruchs 1 einen Kernbereich aus Hartschaum und seitliche Sperrelemente aus einem weicherem Material hat. In der DE 299 18 219 U1 ist eine Fassade offenbart, bei der zwischen Füllungselementen ein Dämmkörper angeordnet ist, der aus unterschiedlichen Materialien hergestellt und über eine Andruckleiste fixiert ist.The EP 2 642 039 A1 discloses an insulating element for a facade structure, which according to the preamble of claim 1 has a core region made of hard foam and lateral blocking elements made of a softer material. In the DE 299 18 219 U1 is a facade disclosed in which between filling elements an insulating body is arranged, which is made of different materials and fixed by a pressure bar.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Isolierleiste für ein Tragprofil zu schaffen, das eine verbesserte Wärmedämmung besitzt.It is therefore an object of the present invention to provide an insulating strip for a support profile, which has an improved thermal insulation.

Zur Lösung dieser Aufgabe wird eine Isolierleiste für ein Tragprofil mit den Merkmalen des Anspruches 1 vorgeschlagen.To solve this problem, an insulating strip for a support profile with the features of claim 1 is proposed.

Die erfindungsgemäße Isolierleiste weist einen Grundkörper auf, der an einer Seite mit mindestens einem Steg für eine Steckverbindung versehen ist, um die Isolierleiste an oder in einer Schraubnut des Tragprofils zu fixieren. Dabei ist der Grundkörper aus einem Hartschaum hergestellt, so dass das Material des Grundkörpers einerseits eine gute Wärmedämmung bereitstellt, da geschäumte Materialien Lufteinschlüsse enthalten, die für eine gute Wärmedämmung sorgen. Andererseits besitzt der Grundkörper aus Hartschaum ausreichende Festigkeitseigenschaften, um die Haltekräfte bereitstellen zu können, die notwendig sind, um die Isolierleiste sicher an oder in einem Tragprofil fixieren zu können. Durch den Einsatz von Hartschaum wird der Einsatz von nicht geschäumten Kunststoffmaterialien entbehrlich, die bei bekannten Isolierleisten für gewisse Wärmeverluste gesorgt haben.The insulating strip according to the invention has a base body which is provided on one side with at least one web for a plug connection in order to fix the insulating strip on or in a screw groove of the supporting profile. In this case, the base body is made of a hard foam, so that the material of the body on the one hand provides good thermal insulation, since foamed materials contain air pockets that provide good thermal insulation. On the other hand, the rigid foam main body has sufficient strength properties in order to be able to provide the holding forces that are necessary in order to be able to fix the insulating strip securely on or in a carrier profile. Through the use of rigid foam, the use of non-foamed plastic materials is dispensable, which have caused in known insulating strips for certain heat loss.

In einer bevorzugten Ausgestaltung weist der Grundkörper mindestens eine Hohlkammer auf. Die Hohlkammer kann dabei zur Führung einer Schraube in die Schraubnut dienen. Bei der Montage können harte Materialien ein Eindrehen einer Schraube von der Außenseite einer Fassade oder eines Lichtdaches in die Schraubnut erschweren, so dass die Anordnung mindestens einer Hohlkammer in dem Grundkörper, die zur Führung der Schraube dient, die Montage vereinfachen kann. Der Benutzer muss lediglich mit der Schraube in die Hohlkammer gelangen, die dann die Schraube so führt, dass diese dann mit der Spitze in die Schraubnut gelangt und dort fixiert werden kann. Die Hohlkammer kann dabei so ausgestaltet sein, dass zwei einander gegenüberliegende Seitenwände als Führungsmittel dienen, die im Wesentlichen fluchtend mit den Wänden der Schraubnut ausgerichtet sind, um die Schraube entsprechend führen zu können. Die Breite der Hohlkammer kann dabei geringfügig größer sein als die der Schraubnut, da für die Führungsfunktion die Schraubnut nicht exakt verlängert werden muss. Die mindestens eine Hohlkammer kann dabei einen rechteckigen Querschnitt aufweisen und wahlweise nur mit Luft sein oder mit einem Isolierkörper gefüllt sein, denn in den Bereichen, in denen keine Schraube in die Hohlkammer eingreift, kann ein entsprechender Isolierkörper für bessere Wärmedämmung sorgen. Der Isolierkörper ist dann vorzugsweise aus einem weicheren Material, das das Eindrehen der Schraube nicht behindert.In a preferred embodiment, the base body has at least one hollow chamber. The hollow chamber can serve to guide a screw in the Schraubnut. During assembly, hard materials can make it difficult to screw a screw from the outside of a facade or a light roof into the screw groove, so that the arrangement of at least one hollow chamber in the base body, which serves to guide the screw, can simplify assembly. The user only has to get into the hollow chamber with the screw, which then guides the screw so that it then reaches the screw groove with the tip and can be fixed there. The hollow chamber can be designed so that two opposing side walls serve as guide means, which are aligned substantially flush with the walls of the screw groove to guide the screw accordingly. The width of the hollow chamber can be slightly larger than that of the screw, since the Schraubnut does not need to be extended exactly for the leadership function. The at least one hollow chamber can have a rectangular cross-section and optionally be only with air or be filled with an insulating body, because in the areas where no screw engages in the hollow chamber, a corresponding insulator provide better thermal insulation. The insulating body is then preferably made of a softer material that does not hinder the screwing of the screw.

Der Grundkörper besteht aus mindestens zwei entlang einer Mittelebene getrennten Teilen, die miteinander verschweißt, verklebt oder anderweitig dauerhaft miteinander verbunden sind. Durch die Ausbildung von zwei Teilen kann das Eindrehen einer Schraube erleichtert werden, insbesondere wenn die Schraube entlang der Mittelebene eingedreht wird. Durch eine symmetrische Ausbildung zweier Teile kann zudem die Herstellung vereinfacht werden, da die beiden Teile aus Hartschaum einfach miteinander verbunden werden können.The main body consists of at least two parts separated along a median plane, which are welded together, glued or otherwise permanently connected to each other. Through the formation of two parts screwing a screw can be facilitated, especially when the screw is screwed in along the median plane. In addition, the production can be simplified by a symmetrical design of two parts, since the two parts made of hard foam can be easily connected to each other.

Die Isolierleiste weist an dem Grundkörper auf der zu dem mindestens einen Steg der Steckverbindung gegenüberliegenden Seite eine Nut zur Fixierung einer Dichtleiste auf. Dadurch kann die Isolierleiste für verschiedene Konstruktionen eingesetzt werden, insbesondere können auch weitere Bauteile wie Zubehörteile, Dichtungen, Dichtungsformteile an der Außenseite gegenüber der Schraubnut fixiert werden. Der Steg der Steckverbindung kann dabei mit ein oder mehreren hervorstehenden Rippen versehen sein, welche aus Hartschaum bestehen und härter als das Material des Steges sein können.The insulating strip has on the base body on the opposite side to the at least one web of the connector a groove for fixing a sealing strip. This allows the insulating strip for different constructions can be used, in particular, other components such as accessories, gaskets, gaskets can be fixed on the outside opposite the screw. The web of the connector can be provided with one or more protruding ribs, which consist of hard foam and may be harder than the material of the web.

Der Grundkörper besteht vorzugsweise aus einem Hartschaum aus Kunststoff, der insbesondere Kunststoffe wie PET, PP, PE und/oder PA enthalten kann. Der Hartschaum weist dabei eine Dichte von weniger als 0,8 g/cm3, insbesondere 0,01 g/cm3 bis 0,5 g/cm3, auf. Durch die geringe Dichte ist sichergestellt, dass der Hartschaum ausreichend Lufteinschlüsse enthält, die in Form von feinen Bläschen fein dispergiert sein können und somit für eine hohe Wärmedämmung sorgen.The main body is preferably made of a rigid foam made of plastic, which may contain in particular plastics such as PET, PP, PE and / or PA. The rigid foam has a density of less than 0.8 g / cm 3 , in particular 0.01 g / cm 3 to 0.5 g / cm 3 , on. The low density ensures that the hard foam contains sufficient air bubbles, which can be finely dispersed in the form of fine bubbles and thus ensure high thermal insulation.

Vorzugsweise weist der Hartschaum zudem eine Shore-Härte von mehr als 50 auf und eine Zugfestigkeit von 20 bis 80 N/mm2. Dadurch ist sichergestellt, dass der Hartschaum eine ausreichende Festigkeit besitzt, um an einer Schraubnut fixiert zu werden.In addition, the hard foam preferably has a Shore hardness of more than 50 and a tensile strength of 20 to 80 N / mm 2 . This ensures that the hard foam has sufficient strength to be fixed to a screw groove.

Die Fixierung in der Schraubnut kann dabei wahlweise über eine Leiste erfolgen, die klemmend in die Schraubnut eingesteckt wird. Alternativ ist es möglich, an der Isolierleiste zwei beabstandete Stege vorzusehen, die die Schraubnut umgreifen, so dass die Isolierleiste von außen auf die Schraubnut aufgerastet wird.The fixation in the screw can be done either via a bar, which is inserted by clamping in the screw. Alternatively, it is possible to provide two spaced webs on the insulating strip, which engage around the screw groove, so that the insulating strip is snapped onto the screw groove from the outside.

Die erfindungsgemäße Isolierleiste wird insbesondere bei einer Fassade, Schrägdach oder einem Lichtdach eingesetzt, bei dem die Isolierleiste zwischen zwei Rändern von Isolierglasscheiben angeordnet wird. Die Isolierleiste ist dann an der Schraubnut des Tragprofils festgelegt und kann in gewissen Abständen von einer Schraube zur Fixierung einer Halteleiste durchgriffen sein.The insulating strip according to the invention is used in particular in a facade, pitched roof or a light roof, in which the insulating strip is disposed between two edges of insulating glass panes. The insulating strip is then fixed to the screw groove of the support profile and can be penetrated at certain intervals by a screw for fixing a retaining strip.

In Figur 1 ist ein Schnitt durch das Tragprofil 2 dargestellt, das zu einer Außenseite hin eine Schraubnut 20 aufweist. Benachbart zu der Schraubnut 20 sind zwei Entwässerungskanäle 21 und Nuten 22 vorgesehene. In jede Nut 22 ist ein Dichtungsfuß 23 einer Dichtleiste 24 eingefügt, an der ein Rand eines Füllungselemtentes, wie einer Isolierglasscheibe, Einsatzelement 4 anliegt. Die Isolierglasscheibe 4 wird dabei über eine Halteleiste 5 fixiert, die durch Schrauben 6 an der Schraubnut 20 festgelegt ist. Die Halteleiste 5 drückt jeweils eine Dichtleiste 7 auf einen äußeren Rand der Isolierglasscheibe 4. Die Halteleiste 5 ist ferner durch eine Abdeckleiste 8 verschlossen.In FIG. 1 is a section through the support section 2 is shown, which has a Schraubnut 20 to an outer side. Adjacent to the screw groove 20, two drainage channels 21 and grooves 22 are provided. In each groove 22, a sealing foot 23 of a sealing strip 24 is inserted, against which an edge of a Füllungselemtentes, such as an insulating glass, insert element 4 is present. The insulating glass 4 is fixed by a retaining strip 5, which is fixed by screws 6 on the screw 20. The retaining strip 5 in each case presses a sealing strip 7 on an outer edge of the insulating glass pane 4. The retaining strip 5 is further closed by a cover strip 8.

In Figur 2 ist der Schnitt durch ein Tragprofil 3 gezeigt, das als Riegel ausgebildet ist und ebenfalls eine Schraubnut 30 aufweist, an deren gegenüberliegenden Seiten Entwässerungskanäle 31 ausgebildet sind. Benachbart zu jedem Entwässerungskanal 31 ist eine Nut 32 vorgesehen, in die ein Dichtungsfuß 33 einer Dichtleiste 34 eingefügt ist. Die horizontalen Ränder von zwei benachbarten Isolierglasscheiben 4 sind an dem Tragprofil 3 festgelegt, wobei wie in Figur 1 über Schrauben 6 eine Halteleiste 5 fixiert ist, die über Dichtleisten 7 auf einen Rand der Isolierglasscheiben 4 drückt.In FIG. 2 the section through a support profile 3 is shown, which is designed as a bolt and also has a screw groove 30, on the opposite sides of drainage channels 31 are formed. Adjacent to each drainage channel 31, a groove 32 is provided, in which a sealing foot 33 of a sealing strip 34 is inserted. The horizontal edges of two adjacent insulating glass panes 4 are fixed to the support section 3, wherein as in FIG. 1 a retaining strip 5 is fixed by screws 6, which presses on sealing edges 7 on an edge of the insulating glass panes 4.

Zwischen benachbarten Stirnseiten der Isolierglasscheiben 4 ist jeweils eine Isolierleiste 10 ausgebildet, die mit einem Steg 13 in die Schraubnut 20 bzw. 30 eingesteckt ist. Es ist auch möglich, die Isolierleiste 10 an der Schraubnut 20 oder 30 derart zu befestigen, dass zwei beabstandete Stege die Schraubnut umgreifen und dort gegebenenfalls verrastet werden können.Between adjacent end faces of the insulating glass panes 4 each have an insulating strip 10 is formed, which is inserted with a web 13 in the screw 20 and 30 respectively. It is also possible to fasten the insulating strip 10 to the screw groove 20 or 30 such that two spaced webs engage around the screw groove and can be latched there if necessary.

In Figur 3 ist die Isolierleiste aus den Figuren 1 und 2 im Detail gezeigt.In FIG. 3 is the insulating strip from the FIGS. 1 and 2 shown in detail.

Die Isolierleiste 10 umfasst einen Grundkörper 11, der aus zwei Teilen 11 a und 11 b besteht, die entlang einer Mittelebene 12 getrennt sind. Die Teile 11 a und 11 b sind dabei zu der Mittelebene 12 symmetrisch ausgebildet und bilden zusammen den Steg 13 aus, der in die Schraubnut 20 oder 30 eingesteckt wird.The insulating strip 10 comprises a base body 11 which consists of two parts 11 a and 11 b, which are separated along a median plane 12.

Der Kunststoff besitzt eine Dichte von weniger als 0,8 g/cm3, insbesondere zwischen 0,01 bis 0,5 g/cm3, so dass viele Luftbläschen in dem Hartschaum eingeschlossen sind und daher eine hohe Wärmeisolierung bereitgestellt wird. Der Hartschaum besitzt dennoch eine hohe Festigkeit, wobei dem Kunststoff Additive zugesetzt sein können, insbesondre ein Blend mit Stabilisatoren, Farbmittel, Färbehilfsmittel, Gleitmittel, Antistatikmittel, Flammschutzmittel. Die Härte des Hartschaums kann mehr als 50 Shore betragen. Die Zugfestigkeit liegt vorzugsweise in einem Bereich zwischen 20 und 80 N/mm2, so dass eine sichere Vorfixierung der Isolierleiste an der Schraubnut möglich ist.The main body 11 consists of a rigid foam made of plastic, which contains PET, PE, PP and / or PA. The plastic has a density of less than 0.8 g / cm 3 , in particular between 0.01 to 0.5 g / cm 3 , so that many air bubbles are trapped in the hard foam and therefore a high thermal insulation is provided. The rigid foam nevertheless has a high strength, wherein the plastic additives may be added, in particular a blend with stabilizers, colorants, dyeing aids, lubricants, antistatic agents, flame retardants. The hardness of the hard foam can be more than 50 Shore. The tensile strength is preferably in a range between 20 and 80 N / mm 2 , so that a secure prefixing of the insulating strip on the screw groove is possible.

Der Steg 13 weist eine Spitze 14 auf, um das Einstecken in die Schraubnut 20 und 30 zu erleichtern. Ferner sind an gegenüberliegenden Seiten Rippen 15 ausgebildet, die ein Einrasten an Rillen der Schraubnut 20 oder 30 ermöglichen, um die Isolierleiste 10 exakt und sicher zu positionieren. Durch die Rippen 15 wird das Eindrücken oder Einschlagen des Steges 13 in die Schraubnut 20 oder 30 durch ein Reingleiten optimiert. Zudem werden höhere Haltekräfte bereitgestellt. Die Rippen 15 können dabei auch aus Hartschaum bestehen, aber härter ausgebildet sein als das übrige Material des Steges 13, um besonders hohe Haltekräfte bereitzustellen.The web 13 has a tip 14 to facilitate insertion into the screw groove 20 and 30. Furthermore, ribs 15 are formed on opposite sides, which allow engagement with grooves of the screw groove 20 or 30 in order to position the insulating strip 10 accurately and securely. By the ribs 15, the impressions or wrapping of the web 13 in the screw groove 20 or 30 is optimized by a Reingleiten. In addition, higher holding forces are provided. The ribs 15 may also consist of hard foam, but be harder than the rest of the material of the web 13 to provide particularly high holding forces.

Der Grundkörper 11 aus Hartschaum weist ferner eine Hohlkammer 16 auf, die sich entlang der Mittelebene 12 erstreckt. Parallel zur Mittelebene 12 verlaufende Seitenwände bilden dabei eine Führung für eine Schraube 6 aus, wenn diese bei der Montage in die Schraubnut 20 oder 30 eingedreht werden soll. Hierfür besitzen die Seitenwände etwa denselben Abstand wie die Wände der Schraubnut 20 oder 30, können aber auch geringfügig mehr beabstandet sein. In jedem Fall wird für die Schraube 6 durch die Hohlkammer 16 eine Führung bereitgestellt, damit diese von der Außenseite im Wesentlichen exakt entlang der Mittelebene 12 eingedreht werden kann.The base body 11 made of hard foam further comprises a hollow chamber 16 which extends along the median plane 12. Parallel to the center plane 12 extending side walls form a guide for a screw 6, if it is to be screwed during assembly in the screw 20 or 30. For this purpose, the side walls have approximately the same distance as the walls of the screw groove 20 or 30, but may also be slightly more spaced. In any case, a guide is provided for the screw 6 through the hollow chamber 16, so that it can be screwed from the outside substantially exactly along the center plane 12.

Das Eindrehen der Schraube 6 wird dabei weiter erleichtert, da der Grundkörper 11 aus zwei Teilen 11 a und 11 b besteht, die an der Außenseite durch eine Verbindungsstelle 18 aneinander gehalten sind. Beim Eindrehen der Schraube ist die Verbindungsstelle 18 erkennbar und kann zur Führung der Spitze der Schraube dienen.The screwing of the screw 6 is further facilitated because the main body 11 consists of two parts 11 a and 11 b, which are held on the outside by a connection point 18 to each other. When screwing the screw, the connection point 18 can be seen and can serve to guide the tip of the screw.

Ferner ist an der Außenseite eine im Querschnitt V-förmige Nut 17 vorgesehen, die ebenfalls das Einführen der Schraube 6 erleichtert. An der Nut 17 sind an gegenüberliegenden Seiten Nutwände 19 mit einem nach innen gerichteten Steg angeformt, so dass an der Nut 17 weitere Bauteile, wie eine Dichtleiste, fixiert werden können.Further, a cross-sectionally V-shaped groove 17 is provided on the outside, which also facilitates the insertion of the screw 6. On the groove 17 groove walls 19 are integrally formed on opposite sides with an inwardly directed web, so that on the groove 17 further components, such as a sealing strip, can be fixed.

Für eine optimierte Wärmedämmung umfasst die Isolierleiste ferner einen Isolierkörper 40, der in die Hohlkammer 16 eingefügt ist. Der Isolierkörper 40 besitzt wie die Hohlkammer 16 einen im Wesentlichen rechteckigen Querschnitt.For an optimized thermal insulation, the insulating strip further comprises an insulating body 40 which is inserted into the hollow chamber 16. The insulating body 40 has like the hollow chamber 16 has a substantially rectangular cross-section.

Der Isolierkörper 40 besteht dabei aus einem weichen Isoliermaterial, das das Eindrehen der Schraube nicht behindert. Insbesondere sind weiche Schaumstoffmaterialien geeignet, die eine hohe Wärmeisolierung besitzen.The insulating body 40 consists of a soft insulating material that does not hinder the screwing of the screw. In particular, soft foam materials which have high heat insulation are suitable.

Ferner besitzt die Isolierleiste 10 an gegenüberliegenden Seiten, die den Stirnseiten der Isolierglasscheiben 4 zugewandt sind, jeweils einen Isolierkörper 41, 42 der an eine Seitenwand des Grundkörpers 11 angeklebt oder angeschweißt sein kann. Der Isolierkörper 41 erstreckt sich über einen Großteil der Länge des Grundkörpers 11 parallel zur Mittelebene 12 und weist auf der zu den Isolierglasscheiben 4 gewandten Seite Stege 43 auf, die den Hohlraum zwischen einer Innen- und einer Außenseite in mehrere Kammern 44 unterteilen. Dadurch wird ein Wärmedurchgang auch in einem Bereich unmittelbar benachbart zu der Stirnseite der Isolierglasscheibe 4 verringert, selbst wenn die Stege 43 nicht an der Isolierglasscheibe 4 anliegen. Die Stege 43 sind dabei nicht rechtwinklig zur Mittelebene 12 ausgerichtet, sondern in einem Winkel, beispielsweise zwischen 50 und 80°, und können daher bei Bedarf umgebogen werden, insbesondere wenn der Abstand zwischen den Isolierglasscheiben 4 sich verringert. Die Montage der Füllungselemente wird hierdurch vereinfacht.Further, the insulating strip 10 has on opposite sides, which face the end faces of the insulating glass panes 4, each having an insulating body 41, 42 which may be glued or welded to a side wall of the base body 11. The insulating body 41 extends over a majority of the length of the base body 11 parallel to the median plane 12 and has on the side facing the insulating glass panes 4 side webs 43, which divide the cavity between an inner and an outer side into a plurality of chambers 44. Thereby, a heat transfer is reduced even in a region immediately adjacent to the end face of the insulating glass pane 4, even if the webs 43 do not rest against the insulating glass 4. The webs 43 are not aligned at right angles to the center plane 12, but at an angle, for example between 50 and 80 °, and therefore can be bent if necessary, especially when the distance between the insulating glass panes 4 is reduced. The assembly of the filling elements is thereby simplified.

Die Isolierkörper 41 können aus dem gleichen Material wie der Isolierkörper 40 bestehen, insbesondere wird ein weiches und elastischeres geschäumtes Material als bei dem Hartschaum eingesetzt. Durch den Einsatz eines weicheren geschäumten Materials können gute Isoliereigenschaften erhalten werden, und zudem ist ein Toleranzausgleich möglich, wenn sich die Abstände zwischen den Isolierglasscheiben verändern, denn die Isolierglasscheiben 4 können über Glasträger 50 in einem vorbestimmten Abstand zur Schraubnut 30 oder der benachbarten Isolierglasscheibe 4 gehalten werden, wie dies in Figur 2 angedeutet wird, wobei dort die untere Isolierglasschiebe 4 auf dem Glasträger 50 aufliegt, so dass Figur 2 zur Darstellung der Einbausituation um 180° gedreht werden muss, da die untere Isolierglasscheibe 4 oberhalb des Glasträgers 50 angeordnet ist.The insulating body 41 may be made of the same material as the insulating body 40, in particular, a soft and elastic foamed material is used as in the rigid foam. By using a softer foamed material good insulating properties can be obtained, and also a tolerance compensation is possible if the distances between the insulating glass change, because the insulating glass 4 can be held on glass carrier 50 at a predetermined distance from the screw 30 or the adjacent insulating glass 4 be like this in FIG. 2 is indicated, where the lower insulating glass slide 4 rests on the glass substrate 50, so that FIG. 2 rotated to show the installation situation by 180 ° must be, since the lower insulating glass pane 4 is arranged above the glass carrier 50.

In dem dargestellten Ausführungsbeispiel umfasst der Grundkörper 11 nur eine Hohlkammer 16. Es ist natürlich auch möglich, mehrere Hohlkammern entlang der Mittelebene 12 vorzusehen, die dann von einer Schraube 6 durchgriffen werden können.In the illustrated embodiment, the base body 11 comprises only a hollow chamber 16. It is of course also possible to provide a plurality of hollow chambers along the median plane 12, which can then be penetrated by a screw 6.
