Description

Die Erfindung betrifft eine Dichtungsanordnung zum Abdichten der Stoßfugen zwischen den Elementen einer Elementfassade mit horizontalen und vertikalen Dichtungsprofilen, die an den Elementstößen angeordnet sind.The invention relates to a sealing arrangement for sealing the butt joints between the elements of an element facade with horizontal and vertical sealing profiles, which are arranged on the element joints.

Elementfassaden sind Vorhangfassaden in Elementbauweise zur Verkleidung von Gebäuden und werden in der in Fig. 1 dargestellten Weise so montiert, dass das jeweils zu montierende Element an das Gebäude herangebracht wird, an das bereits montierte Nachbarelement seitlich angestoßen wird und schließlich abgesenkt wird. Die Elemente sind von den jeweiligen Gebäudedecken über an den Decken sowie an der Rückseite der Elemente angebrachte Halteelemente gehalten.Element facades are prefabricated curtain walls for the cladding of buildings and are used in the in Fig. 1 illustrated manner mounted so that the respective element to be mounted is brought to the building, the already mounted adjacent element is pushed laterally and is finally lowered. The elements are held by the respective building ceilings via attached to the ceilings and at the back of the elements holding elements.

Elementfassaden sind aus Gründen dieser Montageabfolge so konstruiert, dass bauweisebedingte Toleranzen am Kreuzungspunkt der Dichtungen auftreten können. Diese können zu einer Beeinträchtigung des fachmännischen Aussehens sowie der Dichtheit führen, was bislang in Kauf genommen wurde oder mit zusätzlichem Aufwand abgestellt wurde.Element facades are designed for reasons of this assembly sequence so that construction-related tolerances can occur at the intersection of the seals. These can lead to an impairment of the professional appearance as well as the tightness, which was previously accepted or with additional effort turned off.

Unter Windeinwirkung tritt an Gebäuden ein Staudruck und/oder ein Sog auf. Infolge davon treten auch zum Innenraum hin Luftdruckdifferenzen an der Fassade auf. Wenn nun undichte Stellen vorhanden sind, kann ein Luftaustausch mit erheblichen Strömungsgeschwindigkeiten zustande kommen. Dadurch können einerseits Wärmeverluste verursacht werden und kann andererseits Leckwasser oder Kondensat, welches sich im Bereich der Stoßfugen befindet, in den Innenraum befördert werden.When exposed to wind, a build-up of pressure and / or suction on buildings occurs. As a result, air pressure differences on the façade also occur towards the interior. If leaks are present, an air exchange can occur at considerable flow velocities. As a result, on the one hand, heat losses can be caused and, on the other hand, leakage water or condensate, which is located in the region of the butt joints, can be conveyed into the interior space.

Das heißt im Einzelnen, dass bei Elementfassaden naturgemäß Fugen an den Stößen zwischen den Rahmen benachbarter Elemente vorhanden sind. Die Fugenbreite ist dabei so bemessen, dass Maßänderungen der Rahmen der Elemente infolge von Wärmedehnungen sowie auch Lageveränderungen infolge von Gebäudebewegungen aufgenommen werden können. In der Praxis beträgt die Fugenbreite ca. 10 mm. Diese Fugen sind mittels Gummidichtungen in Form von Gummiprofilen verschlossen. Die Gummiprofile werden in der Praxis in drei Ebenen hintereinander angeordnet, um durch die entstehende Labyrinthwirkung die erforderliche Dichtigkeit zu gewährleisten.Specifically, this means that in the case of element facades, joints are naturally present at the joints between the frames of adjacent elements. The joint width is dimensioned so that dimensional changes of the frame of the elements due to thermal expansion and also changes in position as a result of building movements can be included. In practice, the joint width is about 10 mm. These joints are closed by rubber seals in the form of rubber profiles. The rubber profiles are arranged in practice in three levels one behind the other to ensure the required tightness through the resulting labyrinth effect.

Bei der Montage sind die vertikal angeordneten Dichtungsprofile bereits werkstattseitig voreingesetzt, in der Regel in der Weise, dass sie in die Nuten des zuvor angehängten Elements eingesetzt sind, so dass sie beim Heranbringen des nächsten Elements in dessen Aufnahmenuten in Einriff gehen. Die horizontalen Dichtungen werden erst auf der Baustelle und zwar endlos in der Regel über mehrere Elemente hinweg aufgesetzt.During assembly, the vertically arranged sealing profiles are already pre-set in the workshop, usually in such a way that they are inserted into the grooves of the previously attached element, so that they engage in bringing the next element in its receiving grooves. The horizontal seals are placed only on the construction site and that endlessly usually over several elements.

Üblicherweise ist das Auftreffen der vertikalen Dichtungen auf die über mehrere Elemente hinweg endlos aufgesetzten horizontalen Dichtungen als stumpfer Stoß, wie es in Fig. 2 dargestellt ist, oder als Überlappstoß ausgeführt. Aufgrund von Fertigungs- und Montagetoleranzen kann sich in der Praxis ein Spalt oder im Fall von Übermaß eine Deformation an den Dichtungen ergeben, wodurch einerseits ein negatives Erscheinungsbild und andererseits eine verminderte Dichtwirkung die Folge sind. In extremen Fällen muss sogar nachgedichtet werdenUsually, the impact of the vertical seals on the endlessly applied over several elements horizontal seals is as a blunt shock, as in Fig. 2 is shown, or executed as a lap. Due to manufacturing and assembly tolerances may result in practice a gap or in the case of excess deformation on the seals, which on the one hand a negative appearance and on the other hand, a reduced sealing effect are the result. In extreme cases, it must even be re-sealed

Aus der EP 0 467 066 A1 ist eine Dichtungsanordnung gemäß dem Oberbegriff des Anspruchs 1 bekannt.From the EP 0 467 066 A1 a seal assembly according to the preamble of claim 1 is known.

Des Weiteren ist aus der US 3,798,862 A eine Dichtungsanordnung zum Abdichten von Ausfachungen bekannt.Furthermore, from the US 3,798,862 A a sealing arrangement for sealing infills known.

Die der Erfindung zugrunde liegende Aufgabe besteht demgegenüber darin, eine Dichtungsanordnung der eingangs genannten Art zu schaffen, mit der die Dichtigkeit der Stöße zwischen benachbarten Elementen erhöht werden kann.The object underlying the invention is in contrast, a seal assembly of the type mentioned above create, with the tightness of the shocks between adjacent elements can be increased.

Diese Aufgabe wird gemäß der Erfindung durch die Ausgestaltung gelöst, die im Patentanspruch 1 angegeben ist.This object is achieved according to the invention by the embodiment which is specified in claim 1.

Bei der erfindungsgemäßen Dichtungsanordnung stoßen somit am Kreuzungspunkt von vier Elementen einer Elementfassade die vertikalen Dichtungsprofile nicht direkt an die horizontalen Dichtungsprofile an, sondern ist der Stoß der Dichtungsanordnung unter Verwendung von separaten elastischen Dichtungsstücken ausgeführt, die jeweils zwischen den vertikalen Dichtungsprofilen und einem horizontalen Dichtungsstück angeordnet sind. Die zwei zum Kreuzungspunkt laufenden vertikalen Dichtungsprofile treffen mit ihren Stirnseiten stumpf auf die jeweiligen separaten elastischen Dichtungsstücke, welche große Federwege zulassen und im eingebauten Zustand mit Vorspannung auf die Stirnseiten der vertikalen Dichtungsprofile und auf eine Längsseite des horizontalen Dichtungsprofils drücken. Die separaten elastischen Dichtungsstücke liegen satt an den Seitenflächen von Aufnahmenuten an, die an den Rahmen der Elemente vorgesehen sind.In the case of the sealing arrangement according to the invention, therefore, the vertical sealing profiles do not abut directly on the horizontal sealing profiles at the point of intersection of four elements of an element facade. but the shock of the seal assembly is carried out using separate elastic sealing pieces, which are each arranged between the vertical sealing profiles and a horizontal seal piece. The two running to the crossing point vertical sealing profiles meet with their end faces dull on the respective separate elastic sealing pieces, which allow large spring travel and press in the installed state with bias on the faces of the vertical sealing profiles and on a longitudinal side of the horizontal sealing profile. The separate elastic sealing pieces are fed to the side surfaces of receiving grooves, which are provided on the frame of the elements.

Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Dichtungsanordnung sind Gegenstand der Patentansprüche 2 bis 7.Refinements and developments of the seal assembly according to the invention are the subject of claims 2 to 7.

Bei einer anderen Ausführungsform einer Dichtungsanordnung stoßen somit am Kreuzungspunkt von vier Elementen einer Elementfassade die Dichtungsprofile nicht direkt aneinander an, sondern ist der Stoß der Dichtungsanordnung unter Verwendung eines separaten elastischen Dichtstücks ausgeführt. Die vier zum Kreuzungspunkt laufenden Dichtungsprofile treffen mit ihren Stirnseiten stumpf auf das elastische Dichtstück, das große Federwege zulässt und im eingebauten Zustand mit Vorspannung auf die Stirnseiten der Dichtungsprofile drückt. Es liegt satt an den Seitenflächen von Aufnahmenuten an, die in den Rahmen der Elemente vorgesehen sind.In another embodiment of a seal arrangement, therefore, the sealing profiles do not abut each other directly at the point of intersection of four elements of an elementary façade, but the joint of the seal arrangement is executed using a separate elastic sealing piece. The four running to the crossing point sealing profiles meet with their front sides dull on the elastic sealing piece, which allows large spring travel and presses in the installed state with bias on the faces of the sealing profiles. It is fed to the side surfaces of receiving grooves, which are provided in the frame of the elements.

Auf diese Weise lässt sich in wirtschaftlicher Weise die Dichtigkeit von Elementfassaden erhöhen.In this way, the tightness of element facades can be increased in an economical manner.

Ein weiterer Vorteil dieser Ausgestaltung besteht darin, dass die horizontalen Dichtungsprofile nicht mehr auf der Baustelle durchlaufend montiert werden müssen, sondern bereits werkstattseitig angepasst an die Größe des jeweiligen Elementes eingesetzt werden können. Vertikal und horizontal können dabei gleiche Dichtungsprofile vorgesehen sein.Another advantage of this embodiment is that the horizontal sealing profiles no longer need to be continuously mounted on the site, but already workshop side adapted to the size of the respective element can be used. The same sealing profiles can be provided vertically and horizontally.

Wie es in Fig. 1 dargestellt ist, erfolgt bei einer Elementfassade die Montageabfolge der Elemente immer derart, dass ein zu montierendes Element 1 seitlich an ein bereits montiertes Element 2 angestoßen und danach abgesetzt wird. Gehalten werden die Elemente 1 und 2 von Halterungen 4 an den Decken 3 des Gebäudes und entsprechenden Gegenhalterungen, die an der Innenseite der Elemente 1 und 2 vorgesehen sind.As it is in Fig. 1 is shown in an element facade, the assembly sequence of the elements is always such that a to be mounted Element 1 is triggered laterally on an already mounted element 2 and then discontinued. Are kept the elements 1 and 2 of brackets 4 on the ceiling 3 of the building and corresponding mating brackets, which are provided on the inside of the elements 1 and 2.

Wie es in Fig. 2 dargestellt ist, sind zum Abdichten der Stoßfugen von aneinander anstoßenden Elementen 2 Dichtungen in Form von Dichtungsprofilen 5, 6 vorgesehen. Die vertikal angeordneten Dichtungsprofile 5 sind bereits werkstattseitig an den Elementen angebracht, die horizontalen Dichtungsprofile 6 werden endlos über mehrere Elemente hinweg an der Baustelle auf die Elemente 2 aufgesetzt.As it is in Fig. 2 is shown, 2 seals in the form of sealing profiles 5, 6 are provided for sealing the butt joints of abutting elements. The vertically arranged sealing profiles 5 are already mounted on the workshop side of the elements, the horizontal sealing profiles 6 are endlessly placed over several elements at the construction site on the elements 2.

An einem Kreuzungspunkt, an dem vier Elemente 2 aneinanderstoßen, treffen die vertikalen Dichtungsprofile 5 üblicherweise mit einem stumpfen Stoß auf das horizontale Dichtungsprofil 6. Diese bekannte Ausgestaltung kann dazu führen, dass durch Übermaß oder durch das Auftreten von Spalten die Dichtwirkung beeinträchtigt ist.At a crossing point where four elements 2 abut each other, the vertical sealing profiles 5 usually strike the horizontal sealing profile 6 with a blunt impact. This known configuration can lead to an impairment of the sealing effect due to oversizing or the occurrence of gaps.

Fig. 3 zeigt ein Ausführungsbeispiel einer Dichtungsanordnung mit horizontalen Dichtungsprofilen 6 und vertikalen Dichtungsprofilen 5, die an den Rahmen 8 der aneinander anstoßenden Fassadenelemente angebracht sind. Fig. 3 shows an embodiment of a sealing arrangement with horizontal sealing profiles 6 and vertical sealing profiles 5, which are attached to the frame 8 of the abutting facade elements.

Am Kreuzungspunkt der vertikalen und horizontalen Dichtungsprofile 5 und 6 ist ein elastisches Dichtstück 7 vorgesehen, auf das die Dichtungsprofile 5 und 6, die im Abstand von den Ecken der jeweiligen Rahmen 8 enden und damit einen entsprechenden Zwischenraum für das Dichtstück 7 bilden, stumpf auftreffen.At the intersection of the vertical and horizontal sealing profiles 5 and 6, an elastic sealing piece 7 is provided, to which the sealing profiles 5 and 6, which end at a distance from the corners of the respective frame 8 and thus form a corresponding space for the sealing piece 7, butt stump.

Das elastische Dichtstück 7 lässt große Federwege zu und drückt im eingebauten Zustand mit einer Vorspannung auf die Stirnseiten der horizontalen und vertikalen Dichtungsprofile 5 und 6. Es liegt satt an den Seitenflächen von Aufnahmenuten in den Rahmen 8 an.The elastic sealing piece 7 allows large spring travel and presses in the installed state with a bias on the front sides of the horizontal and vertical sealing profiles 5 and 6. It is fed to the side surfaces of grooves in the frame 8 at.

Das in Fig. 3 dargestellte elastische Dichtstück 7 ist rechteckig gestaltet, vorzugsweise ist es ein flächiges quadratisches Dichtstück in Form eines Füllstückes, das den Zwischenraum zwischen den im Abstand von den Ecken der Rahmen 8 endenden Dichtungsprofilen 5 und 6 füllt.This in Fig. 3 shown elastic sealing piece 7 is rectangular, preferably it is a flat square sealing piece in the form of a filler, which fills the gap between the spaced from the corners of the frame 8 sealing profiles 5 and 6.

Das Dichtstück 7 kann allerdings auch kreuzförmig ausgestaltet sein, wie es beispielsweise in Fig. 5 dargestellt ist.However, the sealing piece 7 may also be designed cross-shaped, as for example in Fig. 5 is shown.

Vorzugsweise besteht das Dichtstück 7 aus einem EPDM-Schaumstück, das in Dichtungsaufnahmenuten in den Rahmen 8 eingesetzt ist. Die Federkraft des Schaumstoffes sorgt für einen sicheren Anschluss an die horizontalen und die vertikalen Dichtungsprofile 5 und 6. Falls erforderlich kann zur stirnseitigen Verbindung ein Dichtstoff bzw. ein Klebstoff zusätzlich vorgesehen sein.Preferably, the sealing piece 7 consists of an EPDM foam piece, which is inserted into Dichtungsaufnahmenuten in the frame 8. The spring force of the foam ensures a secure connection to the horizontal and the vertical sealing profiles 5 and 6. If necessary, a sealant or an adhesive may be additionally provided for the frontal connection.

Der EPDM-Schaumstoff, aus dem das Dichtstück 7 gebildet ist, ist vorzugsweise ein geschlossenzelliger Schaumstoff.The EPDM foam from which the sealing piece 7 is formed is preferably a closed-cell foam.

Fig. 4 zeigt ein weiteres Ausführungsbeispiel einer Dichtungsanordnung, bei der das Dichtstück 7 kreuzförmig ausgestaltet ist. Bei diesem Ausführungsbeispiel wirkt der mittlere Teil des Dichtstücks 7 selber nicht toleranzausgleichend, sondern sind nur die Arme des kreuzförmigen Dichtstücks 7 federelastisch ausgestaltet. Falls erwünscht können diese Arme geteilt sein und in die Hohlkammern der horizontalen und vertikalen Dichtungsprofile 5 und 6 als pfropfenförmige Endstücke eingesetzt sein, wie es in Fig. 4 dargestellt ist. Fig. 4 shows a further embodiment of a sealing arrangement in which the sealing piece 7 is designed cross-shaped. In this embodiment, the middle part of the sealing piece 7 itself does not act to compensate tolerance, but only the arms of the cross-shaped sealing piece 7 are designed resiliently. If desired, these arms may be split and inserted into the hollow chambers of the horizontal and vertical sealing profiles 5 and 6 as plug-shaped end pieces as shown in Figs Fig. 4 is shown.

Die Anforderungen an die Dichtigkeit sind naturgemäß bei der zur Gebäudeinnenseite gewandten Dichtung am größten. Vorzugsweise ist daher diese Dichtungsanordnung für die innerste Dichtungsebene vorgesehen, wie es beispielsweise in Fig. 5 anhand der kreuzförmigen Ausgestaltung des Dichtstückes 7 dargestellt ist.Naturally, the requirements for tightness are greatest for the gasket facing the inside of the building. Preferably, therefore, this seal arrangement is provided for the innermost sealing plane, as for example in Fig. 5 is illustrated by the cross-shaped configuration of the sealing piece 7.

Fig. 6 zeigt ein Ausführungsbeispiel der erfindungsgemäßen Dichtungsanordnung mit horizontalen Dichtungsprofilen 6 und vertikalen Dichtungsprofilen 5, die an den Rahmen 8 (nicht gezeigt in Fig. 6) der aneinander anstoßenden Fassadenelemente angebracht werden. Außerdem sind in der Figur 6 jeweilige Querschnittsansichten 13 der jeweiligen Dichtungsprofile 5, 6 dargestellt. Wie ersichtlich weisen die Dichtungsprofile 5, 6 Hohlräume und abgerundete Enden 14 mit Befestigungsvorrichtungen 15, die beispielsweise als Nasen ausgebildet sein können, zum Einrasten in eine entsprechend ausgebildete Einrastvorrichtung auf. Die vertikal angeordneten Dichtungsprofile 5 können bereits werkstattseitig an den Elementen angebracht werden, und die horizontalen Dichtungsprofile 6 können endlos über mehrere Elemente hinweg an der Baustelle auf die Elemente 2 aufgesetzt werden. Die vertikalen Dichtungsprofile 5 enden im Abstand von den Ecken der jeweiligen Rahmen (nicht gezeigt in Figur 6). Fig. 6 shows an embodiment of the seal assembly according to the invention with horizontal sealing profiles 6 and vertical Sealing profiles 5 attached to the frame 8 (not shown in FIG Fig. 6 ) of the abutting facade elements are attached. Also, in the FIG. 6 respective cross-sectional views 13 of the respective sealing profiles 5, 6 are shown. As can be seen, the sealing profiles 5, 6 cavities and rounded ends 14 with fastening devices 15, which may be formed, for example, as lugs, for engaging in a correspondingly formed latching device. The vertically arranged sealing profiles 5 can already be attached to the elements on the workshop side, and the horizontal sealing profiles 6 can be placed endlessly over several elements at the construction site on the elements 2. The vertical sealing profiles 5 terminate at a distance from the corners of the respective frames (not shown in FIG FIG. 6 ).

An jeweiligen Stirnseiten der vertikalen Dichtungsprofile 5 sind separate elastische Dichtstücke 9 angeordnet, welche an das horizontale Dichtungsprofil 6 stumpf anstoßen. Gemäß einer Ausführungsform sind die elastischen Dichtstücke 9 aus weichem Zellgummi ausgebildet. In anderen Ausführungsformen können die elastischen Dichtstücke 9 aus anderen geeigneten elastischen Materialien ausgebildet sein, welche eine Abdichtung bewirken. Die Dichtstücke 9 füllen jeweilige, zwischen den vertikalen Dichtungsprofilen 5 und dem horizontalen Dichtungsprofil 6 ausgebildete Zwischenräume.At respective end faces of the vertical sealing profiles 5 separate elastic sealing pieces 9 are arranged, which butt against the horizontal sealing profile 6 dull. According to one embodiment, the elastic sealing pieces 9 are formed of soft cellular rubber. In other embodiments, the elastic sealing pieces 9 may be formed of other suitable elastic materials which cause a seal. The sealing pieces 9 fill respective, formed between the vertical sealing profiles 5 and the horizontal sealing profile 6 spaces.

Die separaten Dichtstücke 9 können beispielsweise mittels einer Steckverbindung oder durch einen Klebstoff mit den Stirnseiten der entsprechenden vertikalen Dichtungsprofilen 5 verbunden sein. Es können jedoch auch andere Verbindungstechniken verwendet werden, um die separaten Dichtstücke 9 an den Stirnseiten der vertikalen Dichtungsprofile 5 zu befestigen. Im vorliegenden Fall weisen die Dichtstücke 9 an einem dem vertikalen Dichtungsprofil 5 zugewandten Ende, Zapfen 12 auf, welche in die Hohlkammern der vertikalen Dichtungsprofile 5 hineinragen und somit eine Verbindung zwischen den Dichtstücken 9 und den vertikalen Dichtungsprofilen herstellen. Andere dem horizontalen Dichtungsprofil 6 zugewandten Enden der Dichtstücke 9 sind mit einem nach innen gewölbten Hohlprofil ausgebildet, welches an die entsprechenden abgerundeten Enden 14 der horizontalen Dichtungsprofile 6 angepasst ist. In Abhängigkeit von der Ausgestaltung der Enden 14 der horizontalen Dichtungsprofile können die dem horizontalen Dichtungsprofil 6 zugewandten Enden der Dichtstücke 9 auch anders ausgebildet sein. Bevorzugt sind diese Enden der Dichtstücke 9 passgenau an die entsprechenden längsseitigen Enden 14 der horizontalen Dichtungsprofile 6 ausgebildet.The separate sealing pieces 9 may be connected, for example by means of a plug connection or by an adhesive with the end faces of the corresponding vertical sealing profiles 5. However, other joining techniques may be used to secure the separate sealing pieces 9 to the faces of the vertical sealing profiles 5. In the present case, the sealing pieces 9 on a vertical sealing profile 5 facing the end, pin 12, which in the hollow chambers of the vertical sealing profiles 5 protrude and thus produce a connection between the sealing pieces 9 and the vertical sealing profiles. Other horizontal sealing profile 6 facing ends of the sealing pieces 9 are formed with an inwardly curved hollow profile, which is adapted to the corresponding rounded ends 14 of the horizontal sealing profiles 6. Depending on the design of the ends 14 of the horizontal sealing profiles, the horizontal sealing profile 6 facing ends of the sealing pieces 9 may also be designed differently. Preferably, these ends of the sealing pieces 9 are accurately formed on the corresponding longitudinal ends 14 of the horizontal sealing profiles 6.

Wie in Fig. 6 dargestellt, überlappen Endabschnitte 10 der Dichtstücke 9 mit den horizontalen Dichtungsprofilen 6. Durch diese Überlappung wird die Dichtigkeit im Vergleich zu einer herkömmlichen Dichtungsanordnung erhöht.As in Fig. 6 shown, overlap end portions 10 of the sealing pieces 9 with the horizontal sealing profiles 6. By this overlap, the density is increased compared to a conventional seal assembly.

Fig. 7 zeigt eine schematische Querschnittsansicht der in Figur 6 gezeigten erfindungsgemäßen Dichtungsanordnung, wobei zusätzlich Abschnitte von Rahmen 8 zweier übereinander angeordneter Elemente dargestellt sind und das horizontale Dichtungsprofil 6 aus Gründen der Übersichtlichkeit nicht gezeigt ist. Die Rahmen 8 weisen jeweilige Dichtungsaufnahmenuten 11 auf, in denen die Dichtstücke 9 angeordnet sind. Die Dichtungsaufnahmenuten 11 weisen Einrastvorrichtungen 16 auf, in denen die Befestigungsvorrichtungen 15 des horizontalen Dichtungsprofils 6 einrasten (nicht gezeigt in Fig. 7). Die Endabschnitte 10 der Dichtstücke 9 weisen jeweils eine konkave Wölbung auf, die an eine entsprechende konvexe Wölbung der in Fig. 7 nicht gezeigten längsseitigen Enden 14 der horizontalen Dichtungsprofile 6 angepasst ist. Die vertikalen Dichtungsprofile 5 sowie die Dichtstücke 9 können bereits werkstattseitig in die Dichtungsaufnahmenuten 11 eingebracht werden. Die Dichtstücke 9 können jedoch auch erst beim eigentlichen Zusammenbau der einzelnen Elemente in den Dichtungsaufnahmenuten 11 angebracht werden. Die Dichtstücke 9 lassen große Federwege zu und drücken im eingebauten Zustand mit einer Vorspannung auf die Stirnseiten der vertikalen Dichtungsprofile 5 und die Längsseiten der horizontalen Dichtungsprofile 6 und wirken somit toleranzausgleichend. Die Dichtstücke 9 liegen satt an Seitenflächen der Aufnahmenuten 11 in den Rahmen 8 an. In dem in Fig. 7 dargestellten Ausführungsbeispiel sind die Enden 10 der Dichtstücke 9 konkav ausgebildet. In Abhängigkeit von einem Querschnittsprofil der Enden 14 der horizontalen Dichtungsprofile 6 können die Enden 10 der Dichtstücke 9 auch entsprechend angepasst ausgebildet sein. Bevorzugt wird der Raum in der Dichtungsaufnahmenut 11 durch die Dichtstücke 9 und die horizontalen Dichtungsprofile 6 vollständig ausgefüllt, so dass eine gute Dichtung gewährleistet ist. Fig. 7 shows a schematic cross-sectional view of in FIG. 6 Sealing arrangement according to the invention shown, in addition sections of frame 8 of two superimposed elements are shown and the horizontal sealing profile 6 is not shown for reasons of clarity. The frame 8 have respective Dichtungsaufnahmenuten 11, in which the sealing pieces 9 are arranged. The seal receiving grooves 11 have latching devices 16 in which the fastening devices 15 of the horizontal sealing profile 6 engage (not shown in FIG Fig. 7 ). The end portions 10 of the sealing pieces 9 each have a concave curvature, which corresponds to a corresponding convex curvature of in Fig. 7 not shown longitudinal ends 14 of the horizontal sealing profiles 6 is adjusted. The vertical sealing profiles 5 and the sealing pieces 9 can already be introduced into the sealing receiving grooves 11 on the workshop side. However, the sealing pieces 9 can not until the actual assembly the individual elements are mounted in the Dichtungsaufnahmenuten 11. The sealing pieces 9 allow large spring travel and press in the installed state with a bias on the front sides of the vertical sealing profiles 5 and the longitudinal sides of the horizontal sealing profiles 6 and thus have a tolerance-compensating. The sealing pieces 9 are fed to side surfaces of the grooves 11 in the frame 8. In the in Fig. 7 illustrated embodiment, the ends 10 of the sealing pieces 9 are concave. Depending on a cross-sectional profile of the ends 14 of the horizontal sealing profiles 6, the ends 10 of the sealing pieces 9 may also be adapted accordingly. Preferably, the space in the Dichtungsaufnahmenut 11 is completely filled by the sealing pieces 9 and the horizontal sealing profiles 6, so that a good seal is ensured.

Fig. 8 zeigt in einer Fig. 5 entsprechenden Ansicht das Ausführungsbeispiel der erfindungsgemäßen Dichtungsanordnung wie in Fig. 6 und 7 dargestellt. Wie gezeigt läuft das horizontale Dichtungsprofil 6 über den Elementstoß, und insbesondere über den Kreuzungspunkt der horizontalen und der vertikalen Dichtungsprofile hinweg durch. Die vertikalen Dichtungsprofile 5 enden im Abstand von den Ecken der Rahmen 8. Zwischen den vertikalen Dichtungsprofilen 5 und dem horizontal verlaufenden Dichtungsprofil 6 sind jeweilige elastische Dichtstücke 9 vorgesehen, die toleranzausgleichend wirken. Fig. 8 shows in one Fig. 5 corresponding view of the embodiment of the seal assembly according to the invention as in Fig. 6 and 7 shown. As shown, the horizontal sealing profile 6 passes over the element shock, and in particular over the crossing point of the horizontal and vertical sealing profiles away. The vertical sealing profiles 5 terminate at a distance from the corners of the frame 8. Between the vertical sealing profiles 5 and the horizontally extending sealing profile 6 respective elastic sealing pieces 9 are provided which act to compensate tolerance.
