  • Retrofitting of grooves is, for example, for steel support structures or not possible from hollow profiles.

In addition, even with careful manufacture of the sealing frame, it cannot be ensured that water pressed on by wind forces cannot nevertheless pass through.
  • the building facade is also subject to numerous other environmental influences, in particular wind forces, temperature, but also environmental noise.

This is all the more so since the temperature conduction is of considerable importance for metal support structures. Wind forces are able to push water through even very small openings, which is definitely disadvantageous. After all, sound transmissions from outside the building or from the facade are extremely disruptive during construction work into the interior of the building and, if possible, to be prevented.

Abstract

The invention relates to insulating arrangements for facades which, whilst being easy to produce and assemble, have a reliable insulating effect with respect to environmental influences such as weather and sound. According to an embodiment, an internal insulating arrangement (3) comprises a flat seal (5) which can be connected to the support structure and into which conventional insulating frames (6, 7) can be inserted. Joints between elements (20, 21) of the flat seal (5) can be sealed by stuck-on insulating patches (18) over which the insulating frames (6, 7) can be guided. An external insulating arrangement (24), which can have the same construction, is provided with non-return valves (29) for the removal of air and water and also for the prevention of penetration by environmental influences. The ends of a screw connection (25) which are exposed to environmental influences and the ends of the screw connection (25) which are introduced into the support structure are separated by means of a heat-insulating layer (38) between adjoining elements (36, 37) of the screw connection (25), the elements (36, 37) being interconnected such that they are rigid against rotation and undetachable in the axial direction.

Description

Die Erfindung betrifft eine Dichtungsanordnung für Fassaden mit einer gebäudeseitigen Tragkonstruktion aus vertikal verlaufenden Pfostenelementen und horizontal verlaufenden Riegelelementen und mit flächigen Paneelen, die an der vom Gebäude wegweisenden Frontseite der Pfosten- und Riegelemente über jeweilige Dichtungsrahmen anliegend befestigt sind.The invention relates to a sealing arrangement for facades with a building-side support structure made of vertically extending post elements and horizontally extending transom elements and with flat panels which are attached to the front of the post and transom elements facing away from the building via respective sealing frames.

Derartige Gebäudefassaden Konstruktion sind etwa aus DE-A- 4 105 208, DE-B- 2 023 536 oder DE-A-3 202 482 vorbekannt.Building facades of this type are known from DE-A-4 105 208, DE-B-2 023 536 or DE-A-3 202 482.

Zunehmend werden Gebäudefassaden als Metall-Glas-Konstruktionen ausgebildet. Diese Metall-Glas-Fassaden weisen als Grundkonstruktion ein Metallgerüst auf, bei dem einzelne flächige Fassadenelemente, wie Glasfenster und die Bereiche zwischen diesen ausfüllende Glas- aber auch Metall-, Naturstein-, Kunststein- und Kunststoffelemente eingesetzt werden. Im folgenden werden diese Fassadenelemente zusammenfassend als Paneele bezeichnet. Dies auch deshalb, weil vergleichbare Konstruktionen auch mittels Holz-Gerüsten und Holz-Paneelen erzielt werden können. Ferner können auch Sonnenkollektoren in solche Tragkonstruktionen eingesetzt werden.Building facades are increasingly being constructed as metal-glass structures. As a basic construction, these metal-glass facades have a metal frame, in which individual flat facade elements, such as glass windows and the areas between them, glass, but also metal, natural stone, artificial stone and plastic elements are used. In the following, these facade elements are collectively referred to as panels. This is also because comparable constructions can also be achieved using wooden scaffolding and wooden panels. Furthermore, solar collectors can also be used in such supporting structures.

Die Tragkonstruktionen bestehen in üblicher Weise aus vertikal verlaufenden Pfostenelementen und horizontal verlaufenden Riegelementen, die die Querverstrebung der Pfostenelemente untereinander bilden. Nach dem Stand der Technik sind nicht nur Holz-Tragkonstruktionen bekannt, sondern auch solche aus Stahl und Aluminium. Auch Hohlprofile sind bereits verwendet worden.The supporting structures consist in the usual way of vertically extending post elements and horizontally extending locking elements which form the cross bracing of the post elements with one another. According to the prior art, not only wooden supporting structures are known, but also those made of steel and aluminum. Hollow sections have also been used.

Bei der Befestigung der Paneele an der Tragkonstruktion ist wesentlich darauf zu achten, daß Umwelteinflüsse am Durchdringen der Verbindung zwischen Tragkonstruktion und Paneelen gehindert werden. Hierzu ist es üblich, Dichtungsrahmen vorzusehen, die auf die von dem Gebäude wegweisenden Frontseite von Pfosten- und Riegelelementen aufgebracht sind und auf die dann die Paneele aufgelegt werden und unter Druckausübung gegen den Dichtungsrahmen mit der Tragkonstruktion verbunden werden. Die Dichtungsrahmen sind aus handelsüblichen Dichtungselementen hergestellt durch zunächst Zuschneiden auf Länge und miteinander Verkleben. Dies erfolgt meist werkseitig und nicht auf einer Baustelle, da davon auszugehen ist, daß Dichtungsrahmen in größerer Anzahl für ein Bauwerk erforderlich sind. Die Dichtungsrahmen müssen an der Tragkonstruktion befestigt werden. Herkömmlich ist das Einbringen in Nuten in der Tragkonstruktion, jedoch erfordert die Herstellung von Tragkonstruktionen mit Nuten einen erheblichen Aufwand. Eine nachträgliche Anbringung von Nuten ist beispielsweise bei Tragkonstruktionen aus Stahl oder aus Hohlprofilen nicht möglich. Bei Tragkonstruktionen aus Aluminium und aus Holz ist dies mit erheblichem Aufwand verbunden. Selbst bei sorgfältiger Fertigung der Dichtungsrahmen kann darüberhinaus nicht sichergestellt werden, daß durch Windkräfte angepresstes Wasser nicht doch durchtreten kann.When attaching the panels to the supporting structure, it is essential to ensure that environmental influences are prevented from penetrating the connection between the supporting structure and the panels. For this purpose, it is customary to provide sealing frames which are applied to the front of the building, facing away from the post and transom elements, and on which the panels are then placed and connected to the supporting structure under pressure against the sealing frame. The sealing frames are made from commercially available sealing elements by first cutting them to length and gluing them together. This is usually done at the factory and not on a construction site, since it can be assumed that a large number of sealing frames are required for a building. The sealing frames must be attached to the supporting structure. The insertion into grooves in the supporting structure is conventional, but the production of supporting structures with grooves requires considerable effort. Retrofitting of grooves is, for example, for steel support structures or not possible from hollow profiles. With supporting structures made of aluminum and wood, this is associated with considerable effort. In addition, even with careful manufacture of the sealing frame, it cannot be ensured that water pressed on by wind forces cannot nevertheless pass through.

Die Gebäudefassade ist darüberhinaus zahlreichen anderen Umwelteinflüssen unterworfen, insbesondere Windkräften, Temperatur, aber auch Umweltgeräuschen. Ferner soll nach Möglichkeit eine Hinterlüftung der Fassade ermöglicht sein, die zum einen das Gebäude selbst schützt und zum anderen witterungsabhängige Nachteile in dem Hohlraum zwischen Paneelen und Gebäude verhindert. Dies umso mehr, als bei Tragkonstruktionen aus Metall die Temperaturleitung von erheblicher Bedeutung ist. Windkräfte sind in der Lage, Wasser durch auch sehr kleine Öffnungen zu pressen, was auf jeden Fall nachteilig ist. Schließlich sind Schallübertragungen von außerhalb des Gebäudes oder von der Fassade bei Bauarbeiten in das Innere des Gebäudes äußerst störend und nach Möglichkeit zu unterbinden. Dabei ist zu beachten, daß die in der Regel aus Metall bestehende Tragkonstruktion bei Anregung, etwa durch Schwingungen der Paneele, gute Übertragungseigenschaften für Schallwellen besitzt, also nur geringe Körperschalldärnpfung.The building facade is also subject to numerous other environmental influences, in particular wind forces, temperature, but also environmental noise. Furthermore, ventilation of the facade should be made possible where possible, which on the one hand protects the building itself and on the other hand prevents weather-dependent disadvantages in the cavity between the panels and the building. This is all the more so since the temperature conduction is of considerable importance for metal support structures. Wind forces are able to push water through even very small openings, which is definitely disadvantageous. After all, sound transmissions from outside the building or from the facade are extremely disruptive during construction work into the interior of the building and, if possible, to be prevented. It should be noted that the support structure, which is usually made of metal, has good transmission properties for sound waves when excited, for example by vibrations of the panels, i.e. only low structure-borne sound absorption.

Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung eine Dichtungsanordnung für Fassaden anzugeben, die die Dichtungswirkung gegenüber mindestens einem der genannten Umwelteinflüsse zu verbessern vermag. Dabei soll insbesondere eine konstruktiv einfache und kostengünstige Anordnung geschaffen sein.Proceeding from this, it is an object of the present invention to provide a sealing arrangement for facades which can improve the sealing effect against at least one of the environmental influences mentioned. In particular, a structurally simple and inexpensive arrangement should be created.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Die Erfindung wird durch die Merkmale der Unteransprüche weitergebildet. Wie bereits erwähnt, ist es zweckmäßig und vorteilhaft, alle in den genannten Ansprüchen enthaltenen Optionen gemeinsam zu verwirklichen. Jedoch kann es abhängig vom Anwendungsfall genügen, nur eine der jeweiligen Dichtungsanordnungen oder Ausführungsformen von Dichtungsanordnungen vorzusehen.The invention is further developed by the features of the subclaims. As already mentioned, it is expedient and advantageous to realize all the options contained in the claims mentioned together. However, depending on the application, it may be sufficient to provide only one of the respective sealing arrangements or embodiments of sealing arrangements.

Wesentlich bei den anmeldungsgemäßen Dichtungsanordnungen ist dabei, daß die einzelnen Bauelemente der Dichtungsanordnung einfach herstellbar sind, weitestgehend in fabrikmäßiger Ausführung und daß die Montage vor Ort in einfacher Weise erfolgen kann, und zwar ohne unzumutbaren Aufwand bei der Bearbeitung der Tragkonstruktion. An den für die Dichtungswirkung entscheidenden Stellen wird bei der Montage die Aufmerksamkeit des Monteurs nicht beeinträchtigt, so daß eine gleichmäßige Dichtungswirkung erzielt werden kann.It is essential in the case of the sealing arrangements according to the application that the individual components of the sealing arrangement are simple to manufacture, largely in a factory design and that the assembly on site is carried out in a simple manner can, and without unreasonable effort when editing the supporting structure. At the points crucial for the sealing effect, the attention of the fitter is not impaired during assembly, so that a uniform sealing effect can be achieved.

Bauwerke des Hochbaues in vollständiger Skelettbauweise sind altbekannt. Bauwerke, bei denen eine Fassade vorgehängt wird, sind ebenfalls üblich. Beiden Typen von Bauwerken ist gemeinsam, daß eine gebäudeseitige Tragkonstruktion vorgesehen ist, die aus vertikal verlaufenden Pfostenelementen und aus horizontal verlaufenden Riegelelementen zusammengesetzt ist, wobei an der Tragkonstruktion Fassadenelemente befestigt werden. Im allgemeinen handelt es sich um flächige Elemente, wie beispielsweise Isolierverglasungen für Fenster, Solarkollektoren, Glasscheiben, Platten aus Natur- oder Kunststein, aus Kunststoff oder auch aus Holz. Solche Elemente können als Paneele bezeichnet werden. Diese Paneele sind, wie bekannt, an der Tragkonstruktion fest, nach Möglichkeit jedoch lösbar zu befestigen.Structures of building construction in full skeleton construction are well known. Buildings where a facade is hung are also common. Both types of structures have in common that a building-side supporting structure is provided, which is composed of vertically extending post elements and horizontally extending locking elements, facade elements being attached to the supporting structure. In general, there are flat elements, such as insulating glazing for windows, solar collectors, glass panes, plates made of natural or artificial stone, plastic or wood. Such elements can be called panels. As is known, these panels are fixed to the supporting structure, but if possible they can be detachably attached.

Tragkonstruktion und Paneel sind im folgenden nur soweit dargestellt, als dies für die Erläuterung der Erfindung erforderlich ist. Beispielsweise zeigt Fig. 7 ein horizontal verlaufendes Riegelelement 1 im Schnitt sowie als Paneele zwei Isolierverglasungen 2. Fig. 10 zeigt ebenfalls ein Tragkonstruktions-Element, wobei es sich entweder, wie dargestellt, um ein Riegelelement 1 aber auch um ein nichtdargestelltes Pfostenelement handeln kann.The supporting structure and panel are only shown to the extent necessary to explain the invention. For example, Fig. 7 shows a horizontal extending locking element 1 in section and two insulating glazings as panels 2. FIG. 10 also shows a supporting structure element, which, as shown, can either be a locking element 1 but also an unillustrated post element.

Insgesamt ist eine rasterartige Anordnung gebildet. Dabei ist eine Anordnung vorgesehen, bei der die einzelnen Paneele, wie die Isolierverglasungen 2 in für sich bekannter Weise mit den Elementen der Tragkonstruktion wie dem Riegelelement 1 fest, aber lösbar zu verbinden sind. Dies erfolgt bei den hier zugrundegelegten Fassaden dadurch, daß zwischen dem Rand der Isolierverglasung 2 (als Beispiel eines Paneels) und einem randseitigen Auflagebereich des Riegelelements 1 als Teil der Tragkonstruktion eine Dichtungsanordnung 3 vorgesehen ist und beide Elemente 1 und 2 über weiter unten als Beispiel dargestellte Mittel gegeneinander gedrückt werden.Overall, a grid-like arrangement is formed. An arrangement is provided in which the individual panels, such as the insulating glazing 2, are to be firmly but releasably connected to the elements of the supporting structure such as the locking element 1 in a manner known per se. In the facades on which this is based, this takes place in that a sealing arrangement 3 is provided between the edge of the insulating glazing 2 (as an example of a panel) and an edge-side support area of the locking element 1 as part of the supporting structure and both elements 1 and 2 are shown below as an example Means are pressed against each other.

Die rasterartige Anordnung ist aus Fig. 1 ersichtlich.The grid-like arrangement can be seen from FIG. 1.

Gemäß der Erfindung ist an den vom Gebäude wegweisenden Frontseiten 4 der verschiedenen Elemente der Tragkonstruktion im wesentlichen vollflächig zunächst eine Flachdichtung 5 aufgebracht, in deren Randbereiche übliche Dichtungsrahmen 6 und 7 für benachbarte Paneele eingesetzt sind. Hierzu weist die Flachdichtung 5 randseitig im Querschnitt etwa schwalbenschwanzförmige Nuten 8 auf, wobei in deren Bodenabschnitt Lippen 9 vorgesehen sein können. Die Dichtrahmen 6, 7 sind im Schnitt etwa T-förmig ausgebildet, wobei die Längsschenkel 10 im wesentlichen dem Querschnitt der Nuten 8 angepaßt ausgebildet sind und die Querschenkel nach außen weisende Lippen 12 sowie sich durch den gesamten Dichtungsrahmen streckende Hohlräume 13 aufweisen. An mindestens einer der nach innen weisenden Flächen des Querschenkels 11 sind ebenfalls Lippen 14 vorgesehen, und zwar an der beim Rahmen insgesamt außenliegenden Seite. Bei der Montage werden zunächst die Flachdichtungen 5 auf die Frontseiten 4 fest aufgebracht. Eine Art der Befestigung wird weiter unten näher geschildert. Die Befestigung kann auch durch Verklebung erfolgen. Anschließend werden die Dichtungsrahmen 6 und 7 über das Einführen deren Längsschenkel 10 in die Nuten 8 der Flachdichtung 5 eingedrückt. Aufgrund der Eigenelastizität der verschiedenen Dichtungselemente, insbesondere auch des randseitig benachbarten Abschnittes 15 neben den Nuten 8 ist das Einführen der Dichtungsrahmen 6, 7 ohne große Schwierigkeiten möglich. Die Dichtungsrahmen 6, 7 selbst sind üblicherweise aus Strangmaterial bereits werksseitig oder fabriksmäßig hergestellt, wobei die entsprechenden Stoßstellen miteinander verschweißt, verklebt oder vulkanisiert sind.According to the invention, a flat gasket 5 is initially applied over the entire surface of the front faces 4 of the various elements of the supporting structure that point away from the building, in the edge areas of which conventional sealing frames 6 and 7 are used for adjacent panels. For this purpose, the flat seal 5 has, on the edge side, approximately dovetail-shaped grooves 8 in cross-section, wherein lips 9 can be provided in the bottom portion thereof. The sealing frames 6, 7 are approximately T-shaped in section, the longitudinal legs 10 being essentially adapted to the cross-section of the grooves 8 and the transverse legs having lips 12 pointing outwards and cavities 13 extending through the entire sealing frame. Lips 14 are likewise provided on at least one of the inwardly facing surfaces of the transverse leg 11, specifically on the side lying on the outside of the frame. During assembly, the flat seals 5 are first firmly attached to the front sides 4. A type of attachment is described in more detail below. The attachment can also be done by gluing. The sealing frames 6 and 7 are then pressed into the grooves 8 of the flat seal 5 by inserting their longitudinal legs 10. Due to the inherent elasticity of the various sealing elements, in particular also the section 15 adjacent to the edge next to the grooves 8, the insertion of the sealing frames 6, 7 is possible without great difficulty. The sealing frames 6, 7 themselves are usually already made from extruded material at the factory or in the factory, the corresponding joints being welded, glued or vulcanized to one another.

Die Flachdichtung 5 kann dabei Einlagen aus wärmedämmendem und/oder schalldämmendem und/oder verstärkendem Material enthalten, wobei für letzteres beispielsweise Glasfasern oder Karbonfasern in Frage kommen. Als wärme- und schalldämmendes Material ist beispielsweise eine Korkeinlage 16 möglich, die in dem Abschnitt zwischen den beiden Nuten 8 der Flachdichtung 5 in diese eingesetzt ist. Dargestellt ist eine vollständig eingebettete Korkeinlage 16. Jedoch kann auch die Rückseite der Flachdichtung, wie in Fig. 7 schematisch dargestellt, offen sein, also dort die Einlage 16 freilegen und direkt an die zugehörigen Elemente der Tragkonstruktion, in Fig. 7 dem Riegelelement 1 anliegen. Es sind auch andere Materialien denkbar, beispielsweise Kunststoffe wir Styropor und dgl., aber auch Mischungen davon. Zweckmäßig ist jedoch, daß diese Einlage 16 bereits werksseitig in die Flachdichtung 5 eingesetzt ist.The flat gasket 5 can contain inserts made of heat-insulating and / or sound-absorbing and / or reinforcing material, glass fibers or carbon fibers being suitable for the latter, for example. A cork insert 16, which is inserted in the section between the two grooves 8 of the flat gasket 5, is possible, for example, as the heat and sound-insulating material. A completely embedded cork insert 16 is shown. However, the rear side of the flat gasket, as shown schematically in FIG. 7, can also be open, that is to say expose the insert 16 there and lie directly against the associated elements of the supporting structure, the locking element 1 in FIG. 7 . Other materials are also conceivable, for example plastics such as polystyrene and the like, but also mixtures thereof. It is useful, however, that this insert 16 is already inserted in the flat gasket 5 at the factory.

Es ist einzusehen, daß bei den Abmessungen eines Gebäudes Flachdichtungen 5 im erforderlichen Umfang nicht werksseitig oder fabrikmäßig vorgesehen sein können. Die Flachdichtung 5 wird daher als Halbzeug in Form von Strangmaterial zur Verfügung stehen, wobei die einzelnen Längsabschnitte in der einfachsten Ausführungsform abgelängt werden können. An den Stoßstellen der einzelnen Elemente besteht nun die latente Gefahr, daß die Dichtungswirkung nicht erzielt wird, beispielsweise bereits durch ungenauen Schnitt und/oder ungenaue Anbringung bei der Montage.It can be seen that, given the dimensions of a building, flat seals 5 cannot be provided in the factory or in the factory to the extent required. The flat gasket 5 will therefore be available as a semifinished product in the form of strand material, the individual longitudinal sections being cut to length in the simplest embodiment. At the joints of the individual elements there is a latent danger that the sealing effect will not be achieved, for example due to an imprecise cut and / or imprecise attachment during assembly.

Eine sichere Abdichtung im Dichtungsstoß kann in der aus den Fig. 3 bis 5 ersichtlichen Weise erzielt werden.A secure seal in the sealing joint can be achieved in the manner shown in FIGS. 3 to 5.

Zweckmäßig ist zunächst, daß nicht ein stumpfer Stoß vorliegt, sondern eine ineinander verzahnend eingreifende Ausbildung der beiden beteiligten Stirnflächen, etwa nach Art der ineinander eingreifenden Elemente von Puzzles oder in der Art einer Schwalbenschwanzverbindung. Eine solche Trennlinie 17 ist in Fig. 3 in Strichlinien dargestellt, und zwar dort als in symmetrischer im wesentlichen schwalbenschwanzförmiger Darstellung. Dabei kann auch eine stufenartige Überdeckung (nicht dargestellt) oder schräge Überdeckung (ebenfalls nicht dargestellt) vorgesehen sein. Vorteilhaft ist jedoch eine zusätzliche Absicherung und Abdichtung im Bereich der Trennlinie 17. Dies wird durch einen in diesem Bereich, und zwar im Bereich zwischen den beiden Nuten 8 der Flachdichtung 5 über die Trennlinie 17 vollständig geklebten Dichtungsflecken 18 erzielt. Zweckmäßig enthält der Dichtungsflecken 18 umlaufend randseitig auslaufende Abflachungen 19, wie sie beispielsweise bei Reparaturflecken für die Reparatur von Löchern in Fahrradschläuchen grundsätzlich bekannt sind. Zweckmäßig reichen dabei die Abflachungen 19 bis sehr nahe an die Nuten 8 heran, auf jeden Fall soweit, daß nach anschließendem Einsetzen der Dichtungsrahmen 6, 7 die Lippen 14 auf diese Abflachungen 19 zur Auflage kommen. Hierdurch wird erreicht, daß nach Anbringen der Paneele selbst bei ungenauem Schnitt oder ungenauer Anordnung der verschiedenen Elemente der Flachdichtung 5 im Bereich der Trennlinie 17 die Dichtungswirkung sichergestellt ist, selbst wenn beispielsweise Wasser unter hohem Winddruck ansteht.It is useful first of all that there is not a blunt joint, but rather an interlocking design of the two end faces involved, for example in the manner of the interlocking elements of puzzles or in the manner of a dovetail connection. Such a dividing line 17 is shown in broken lines in FIG. 3, specifically there as a symmetrical, essentially dovetail-shaped representation. A step-like overlap (not shown) or oblique overlap (also not shown) can also be provided. However, an additional securing and sealing in the area of the dividing line 17 is advantageous. This is achieved by a sealing patch 18 completely glued in this area, specifically in the area between the two grooves 8 of the flat seal 5 via the dividing line 17. The sealing patch 18 expediently contains flats 19 which run out all the way around the edge, as they do for example, in the case of repair stains for the repair of holes in bicycle tubes. The flats 19 expediently extend very close to the grooves 8, in any case to the extent that after subsequent insertion of the sealing frames 6, 7, the lips 14 come to rest on these flats 19. This ensures that after the panels have been attached, even with an inaccurate cut or inaccurate arrangement of the various elements of the flat seal 5 in the region of the dividing line 17, the sealing effect is ensured, even if, for example, water is present under high wind pressure.

Da es im allgemeinen schwierig ist, die Trennlinie 17 an der Baustelle vorzusehen, selbst wenn etwa eine entsprechende Stanze vorhanden sein sollte, ist es zweckmäßig, werksseitig abgelängte Längselemente und werksseitig vorbereitete Kreuzungselemente mit jeweils kompatiblem Verlauf der Stoßstellen im Bereich der künftigen Trennlinien 17 vorzusehen. Fig. 1 zeigt dies in Aufsicht. Es handelt sich dabei um Längselemente 20, die individuell nach dem jeweiligen Gebäude anzulängen sind und auch entsprechend davon unterschiedliche Länge besitzen können, ob sie auf einem Riegelelement 1 oder einem Pfostenelement anzubringen sind und um Kreuzungselemente 21, bei denen zweckmäßig alle Schenkel gleich ausgebildet sind. Wie aus Fig. 2 ersichtlich, können diese Kreuzungselemente 21 beispielsweise mittige Verstärkungselemente 22 tragen, die deren Anbringung vereinfacht. Im Querschnitt entsprechen sie den Längselementen 20 und besitzen insbesondere den Querschnitt gemäß Fig. 6.Since it is generally difficult to provide the dividing line 17 at the construction site, even if a corresponding punch should be present, it is expedient to provide longitudinal elements cut to length at the factory and crossing elements prepared at the factory, each with a compatible course of the joints in the area of the future dividing lines 17. Fig. 1 shows this in supervision. These are longitudinal elements 20 which are to be cut individually according to the respective building and can also have different lengths depending on whether they are to be attached to a locking element 1 or a post element and crossing elements 21 in which all the legs are expediently of the same design. As can be seen from FIG. 2, these crossing elements 21 can, for example, carry central reinforcing elements 22 which simplify their attachment. In cross section they correspond to the longitudinal elements 20 and in particular have the cross section according to FIG. 6.

Nach Verlegung einer derart ausgebildeten Dichtungsanordnung 3 aus Flachdichtung 5 und eingesetztem Dichtungsrahmen 6 bzw. 7 werden die Paneele, beispielsweise die Isolierverglasungen 2, aufgelegt und in herkömmlicher Weise in fester oder lösbarer Verbindung gegen die Elemente der Tragkonstruktion unter Zwischenlage der Dichtungsanordnung 3 gedrückt. An keiner Stelle besteht die Gefahr einer Lücke in der Dichtungsanordnung 3, so daß sicher das Eindringen von Wasser verhindert werden kann. Durch die erwähnte Einlage 16 kann eine Schall- und/oder Wärmedämmung erreicht werden.After laying such a sealing arrangement 3 made of flat gasket 5 and inserted sealing frame 6 or 7, the panels, for example the insulating glazing 2, are placed and pressed in a conventional manner in a fixed or detachable connection against the elements of the supporting structure with the sealing arrangement 3 being interposed. At no point is there a risk of a gap in the sealing arrangement 3, so that the ingress of water can be reliably prevented. Sound and / or thermal insulation can be achieved by means of the insert 16 mentioned.

Es ist nun keineswegs unüblich, bei derartigen Fassadenkonstruktionen eine dem Verlauf der Tragkonstruktion im wesentlichen folgende äußere Leistenanordnung zu verwenden und diese über eine Schraubverbindung mit der Tragkonstruktion derart zu verbinden, daß die Leisten die Paneele gegen die Tragkonstruktion drücken. Dies wird anhand Fig. 7 näher erläutert.It is by no means uncommon to use an outer strip arrangement which essentially follows the course of the support structure in such facade constructions and to connect it to the support structure by means of a screw connection in such a way that the strips press the panels against the support structure. This is explained in more detail with reference to FIG. 7.

Fig. 7 zeigt zunächst in bereits erläuterter Weise ein Riegelelement 1 mit aufgesetzter Flachdichtung 5 und darin eingesetzten Dichtungsrahmen 6 und 7. Als Paneele sind dort Isolierverglasungen 2 aufgesetzt. Über eine hier im Querschnitt durch ein U-Profil gebildete Leiste 23 und eine mit dieser verbundenen äußeren Dichtungsanordnung 24, die beispielsweise im Aufbau der inneren Dichtungsanordnung 3 identisch sein kann, die aber auch eine einteilige Ausbildung besitzen kann, wird mittels einer Schraubverbindung 25, die weiter unten näher erläutert wird, zwischen der Leiste 23 und dem Riegelelement 1 zunächst die Verbindung zwischen diesen hergestellt und dann die Druckkraft zum Gegeneinanderdrücken der verschiedenen Elemente, unter insbesondere Zusammendrücken der Dichtungsrahmen 6 und 7 in der innerenDichtungsanordnung 3 und entsprechender Dichtungselemente 26 bzw. 27 der äußeren Dichtungsanordnung 24 erreicht. Mit einer solchen Anordnung ist es möglich, Toleranzen der Gesamtkonstruktion zu begegnen, da die verschiedenen Dichtungsanordnungen nicht nur Elastizität in Richtung auf das Gebäude zu und von diesem weg, sondern auch in Richtung quer dazu besitzen, ohne daß die Dichtungswirkung verloren ginge.FIG. 7 shows, in the manner already explained, a locking element 1 with a flat gasket 5 attached and sealing frames 6 and 7 inserted therein. Insulating glazing 2 is placed there as panels. Via a strip 23 formed here in cross-section by a U-profile and an outer sealing arrangement 24 connected to it, which can be identical, for example, in the construction of the inner sealing arrangement 3, but which can also have a one-piece design, is by means of a screw connection 25 is explained in more detail below, between the bar 23 and the locking element 1, first the connection between them is established and then the compressive force for pressing the various elements against one another, in particular compressing the sealing frames 6 and 7 in the inner sealing arrangement 3 and corresponding sealing elements 26 and 27 respectively outer seal assembly 24 reached. With such an arrangement, it is possible to meet tolerances of the overall construction, since the various sealing arrangements have not only elasticity towards and away from the building, but also in the direction transverse to it, without the sealing effect being lost.

Es ist dabei von Vorteil, den Raum 28 zwischen den durch die Isolierverglasungen 2 gebildeten Paneelen und den beiden Dichtungsanordnungen 3 und 24 entlüften zu können oder auch von etwa eingedrungenem Wasser befreien zu können, andererseits jedoch zu verhindern, daß Umwelteinflüsse insbesondere Windruck eintritt.It is advantageous to be able to vent the space 28 between the panels formed by the insulating glazing 2 and the two sealing arrangements 3 and 24 or to be able to remove any water that may have penetrated, but on the other hand to prevent environmental influences, in particular wind pressure, from occurring.

Beispielsweise und gemäß einem Merkmal der Erfindung kann in der äußeren Dichtungsanordnung 24 ein Einwegeventil 29 vorgesehen sein, das zwar das Austreten von Wasser und/oder Luft aus dem Raum 28 nach Außen ermöglicht, jedoch das Eintreten von Luft von Außen verhindert. Im einfachsten Fall weist dabei das entsprechende rahmenförmige Dichtungselement 27 an der vertikal unten liegenden Seite der äußeren Dichtungsanordnung 24 an einzelnen Stellen ein Kunststoffrohr 30 auf, an dessen, im Hinblick auf das Gebäude und den Raum 28 gesehen, Außenseite eine Lasche 31 so teilweise befestigt und teilweise lose vorgesehen ist, daß unter Ausnutzung der Eigenelastizität im Normalzustand der Schließzustand vorgegeben ist, wobei bei gewissem Druck aus dem Raum 28, etwa durch erwärmte und sich ausdehnende Luft oder durch Wasser, die Lasche 31 nach außen ausgelenkt wird, so daß das Ventil öffnet, wobei dann, wenn Wind drückt, das Kunststoffrohr 30 durch die Lasche 31 geschlossen ist. Beim Ausführungsbeispiel ist eine im wesentlichen rechteckige Lasche 31 vorgesehen. Diese kann jedoch entsprechend dem Querschnitt des Kunststoffrohrs 30 auch eine andere geometrische Form besitzen. Einwegventile dieser Art sind grundsätzlich bekannt, etwa bei Blasebalgen oder dgl..For example and in accordance with a feature of the invention, a one-way valve 29 can be provided in the outer sealing arrangement 24, which valve allows water and / or air to escape from the space 28 to the outside, but prevents the entry of air from the outside. In the simplest case, the corresponding frame-shaped sealing element 27 has a plastic tube 30 on the vertically lower side of the outer sealing arrangement 24, on the outside of which, with regard to the building and the space 28, a tab 31 is partially attached and It is provided in part loosely that the closed state is predetermined in the normal state, taking advantage of the inherent elasticity, the flap 31 being deflected outwards at a certain pressure from the space 28, for example by heated and expanding air or by water, so that the valve opens , when the wind is blowing, the plastic tube 30 is closed by the tab 31. In the exemplary embodiment, a substantially rectangular tab 31 is provided. However, this can correspond to the cross section of the plastic tube 30 also have a different geometric shape. One-way valves of this type are generally known, for example in bellows or the like.

Die Schraubverbindung 25 kann nun eine wärmeleitende oder, was nachteiliger ist, eine kälteleitende Brücke darstellen. Wie aus Fig. 7 ersichtlich ist ein Bolzenkopf 32 außerhalb der Fassade im Bereich der Leiste 23 vorgesehen. Die Schraubverbindung 25 durchsetzt dabei sowohl die Leiste 23 als auch den Raum 28 und die beiden Dichtungsanordnungen 3 und 24 und tritt, wie das insbesondere aus Fig. 10 hervorgeht, in die Tragkonstruktion, hier das Riegelelement 1 ein. Zwar kann eine gewisse Dichtungswirkung im Bereich der Dichtungsanordnungen 3 und 24 dadurch erreicht werden, daß die entsprechende Öffnung für den Durchtritt der Schraubverbindung 25 etwas kleiner gestaltet ist als der Durchmesser der Schraubverbindung 25, so daß ein elastisches Anliegen erfolgt, jedoch wird dadurch die kälteleitende Brücke nicht unterbrochen.The screw connection 25 can now be a heat-conducting or, which is more disadvantageous, a cold-conducting bridge. As can be seen from FIG. 7, a bolt head 32 is provided outside the facade in the area of the strip 23. The screw connection 25 penetrates both the strip 23 and the space 28 and the two sealing arrangements 3 and 24 and, as can be seen in particular from FIG. 10, enters the supporting structure, here the locking element 1. A certain sealing effect in the area of the sealing arrangements 3 and 24 can indeed be achieved in that the corresponding opening for the passage of the screw connection 25 is made somewhat smaller than the diameter of the screw connection 25, so that there is an elastic contact, but the cold-conducting bridge is thereby not interrupted.

Dies gilt selbst dann, wenn aus praktischen Erwägungen heraus die Schraubverbindung zweiteilig ausgebildet ist nämlich einerseits durch eine bei der Befestigung der innenliegenden Dichtungsanordnung 3 verwendetes und in die Tragkonstruktion eingeschraubtes erstes Teil 33 mit einer stirnseitigen Gewindebohrung 34 und einem zweiten den Bolzenkopf 32 enthaltenden außenliegenden Bolzenteil 35 das nach Aufsetzen der Leiste 23 diese durchsetzt und in die Gewindebohrung 34 des ersten Teils 33 eingeschraubt wird. Die Kältebrücke bleibt dadurch jedoch beibehalten.This applies even if, for practical reasons, the screw connection is formed in two parts, namely on the one hand by a first part 33 used in the fastening of the internal sealing arrangement 3 and screwed into the supporting structure with an end threaded bore 34 and a second external bolt part 35 containing the bolt head 32 that after placing the bar 23 passes through it and is screwed into the threaded bore 34 of the first part 33. However, the cold bridge remains.

Eine Unterbrechung der Kältebrücke wird bei der Ausführungsform gemäß Fig. 10 und 11 sichergestellt. Bei dieser Ausführungsform ist das erste Teil 33 der Schraubverbindung 25 mehrteilig ausgebildet. Ein erstes Element 36 und ein zweites Element 37 weisen zueinander komplementäre derartige räumliche Trennflächen auf, daß, wie sich auf Fig. 10 und 11 ergibt, im zusammengesetzen Zustand, bei dem die Achsen auf einer gemeinsamen Achse liegen, die auch die gemeinsame Achse der Schraubverbindung 25 darstellt, die beiden Elemente 36 und 37 in axialer Richtung nicht voneinander trennbar sind jedoch in mindestens einer zur Achse senkrechten Richtung auseinander führbar bzw. ineinander führbar sind. Die Trennebene kann dabei einen aus Fig. 10 ersichtlichen schwalbenschwanzförmigen Verlauf besitzen. Es ist ferner erforderlich, daß aus technischen Gründen eine drehfeste Verbindung erzielt ist. Die tatsächliche Ausbildung und Bemessung des ersten Teils 33 der Schraubverbindung 25 und dessen beider Elemente 36 und 37 ist ausschließlich durch statische Erfordernisse bestimmt. Im Bereich dieser Trennflächen ist vorteilhaft zur Unterbrechung der Kältebrücke eine entsprechende Wärmedämmschicht 38 eingebracht. Vorzugsweise erfolgt eine fest Verbindung der beiden Elemente 36, 37 und der Wärmedämmschicht 38 wie eine Verklebung.An interruption of the cold bridge is ensured in the embodiment according to FIGS. 10 and 11. In this embodiment, the first part 33 of the screw connection 25 is formed in several parts. A first element 36 and a second element 37 have mutually complementary spatial separating surfaces such that, as can be seen in FIGS. 10 and 11, in the assembled state, in which the axes lie on a common axis, which is also the common axis of the screw connection 25, the two elements 36 and 37 cannot be separated from one another in the axial direction, but can be guided apart or into one another in at least one direction perpendicular to the axis. The parting plane can have a dovetail shape as shown in FIG. 10. It is also necessary that a non-rotatable connection is achieved for technical reasons. The actual design and dimensioning of the first part 33 of the screw connection 25 and its two elements 36 and 37 is determined exclusively by static requirements. In the area of these dividing surfaces is advantageous for Interruption of the cold bridge, a corresponding thermal insulation layer 38 is introduced. Preferably, the two elements 36, 37 and the heat insulation layer 38 are firmly connected like an adhesive bond.

Von Vorteil ist dabei, daß das erste Teil 33 der Schraubverbindung 25 vollständig fabrikmäßig hergestellt werden kann.The advantage here is that the first part 33 of the screw connection 25 can be completely manufactured in the factory.

Bei geeigneter Eigensteifigkeit der Dichtungsanordnung 3 insbesondere der Flachdichtung 5 ist es nicht erforderlich eine eigene Verbindungsanordnung zur Verbindung der Flachdichtung 5 mit dem Riegelelement 1 bzw. dem Pfostenelement vorzusehen. In der Praxis werden vor Ort, d.h. an der Baustelle selbst, entsprechende Gewindebohrungen 39 in der Tragkonstruktion vorgesehen. In diese wird dann das erste Teil 33 der Schraubverbindung 25 eingeschraubt. In der Flachdichtung 5 werden dann zugehörige Löcher gestanzt, die wie erwähnt einen kleineren Durchmesser als der Durchmesser des ersten Teils 33 der Schraubverbindung 25 besitzen sollten. Es genügt dann die Flachdichtung 5 mittels dieser Löcher über die ersten Teile 33 zu schieben und gegen die Frontseite 4 des Riegelelements 1 bzw. des Pfostenelements zu drücken. Es werden dann die Dichtungsflecken 18 und anschließend die Dichtungsrahmen 6 und 7 in der beschriebenen Weise angebracht. Die Paneele wie die Isolierverglasungen 2 werden dann angebracht und mittels der Leisten 23 und der zugehörenden Dichtungsanordung 24 dadurch gegeneinander und gegen die Elemente der Tragkonstruktion gedrückt, daß das Bolzenteil 35 als zweites Teil der Schraubverbindung 25 in die zugehörige Gewindebohrung 40 des ersten Teils 33 bzw. dessen ersten Elements 36 eingeschraubt wird.With a suitable inherent rigidity of the sealing arrangement 3, in particular the flat seal 5, it is not necessary to provide a separate connection arrangement for connecting the flat seal 5 to the locking element 1 or the post element. In practice, at the construction site itself, corresponding threaded holes 39 are provided in the supporting structure. The first part 33 of the screw connection 25 is then screwed into this. Associated holes are then punched in the flat seal 5, which, as mentioned, should have a smaller diameter than the diameter of the first part 33 of the screw connection 25. It is then sufficient to push the flat gasket 5 by means of these holes over the first parts 33 and to press it against the front side 4 of the locking element 1 or the post element. The sealing patches 18 and then the sealing frames 6 and 7 are then attached in the manner described. The panels, such as the insulating glazing 2, are then attached and, by means of the strips 23 and the associated sealing arrangement 24, pressed against one another and against the elements of the supporting structure such that the bolt part 35 as the second part of the screw connection 25 into the associated threaded bore 40 of the first part 33 or whose first element 36 is screwed in.

Zur Vollständigkeit ist zu erwähnen, daß die Dichtungselemente 26 und 27 der außenliegenden Dichtungsanordnung 24 ebenfalls Hohlräume wie die Hohlräume 13 der innenliegenden Dichtungsanordnung 3 bzw. der Dichtungsrahmen 6 und 7 aufweisen ebenso wie Lippen zur Verbesserung der Dichtungswirkung. Ferner kann die außenliegende Dichtungsanordnung 24 ebenfalls Einlagen aufweisen wie die innenliegende Dichtungsanordung 3.For completeness it should be mentioned that the sealing elements 26 and 27 of the outer sealing arrangement 24 also have cavities such as the cavities 13 of the inner sealing arrangement 3 or the sealing frame 6 and 7, as well as lips to improve the sealing effect. Furthermore, the external sealing arrangement 24 can also have inlays like the internal sealing arrangement 3.

Zusammenfassend wird eine aus einfachen Elementen aufgebaute Dichtungsanordnung angegeben, die einfach montiert werden kann und trotzdem sicher hohe Dichtungswirkung gegen Umwelteinflüsse erreicht, insbesondere Witterungseinflüsse und Schalleinflüsse.In summary, a sealing arrangement made up of simple elements is specified which can be easily installed and nevertheless achieves a high sealing effect against environmental influences, in particular weather and sound influences.
