Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft eine Tragstruktur für Fassadenelemente sowie eine Gebäudefassade umfassend eine solche Tragstruktur gemäss den Oberbegriffen der unabhängigen Patentansprüche.The invention relates to a support structure for facade elements and a building facade comprising such a support structure according to the preambles of the independent claims.

STAND DER TECHNIKSTATE OF THE ART

Aus dem Stand der Technik ist es bekannt, Gebäudefassaden derartig zu erstellen, dass plattenförmige Fassadenelemente, z.B. aus Glas, an einer tragfähigen Fassadenunterkonstruktion bzw. Tragstruktur befestigt werden, welche zum Beispiel als Pfosten-Riegel-Konstruktion aus schweren Metallprofilen ausgeführt sein kann.It is known from the prior art to create building facades in such a way that plate-shaped facade elements, e.g. made of glass, are attached to a load-bearing facade substructure or support structure, which can be designed, for example, as a post-and-rail construction made of heavy metal profiles.

Die Vertikallasten der Fassadenelemente werden dabei über Tragelemente, die an der Fassadenunterkonstruktion angeschweisst oder angeschraubt sind, auf die Fassadenunterkonstruktion übertragen.The vertical loads of the facade elements are transferred to the facade substructure via support elements that are welded or screwed to the facade substructure.

Bei angeschweissten Tragelementen ergibt sich der Nachteil, dass sich eine wirkungsvolle Abdichtung der Fassadenkonstruktion gegenüber der Fassade im Auflagerbereich äussert schwierig gestaltet. Ein weiterer Nachteil besteht darin, dass es bei bereits in der Fabrik angeschweissten Tragelementen bei der Montage vor Ort zu Positionsabweichungen kommen kann. Andererseits erfordert ein Anschweissen der Tragelemente erst bei der Montage auf der Baustelle oftmals Schweissarbeiten in schwierigen bzw. gefährlichen Montagesituationen, was zu vermeiden ist.In the case of welded-on support elements, there is the disadvantage that an effective sealing of the facade structure against the facade in the support area is extremely difficult. Another disadvantage is that if the support elements have already been welded on in the factory, there may be positional deviations during assembly on site. On the other hand, welding of the supporting elements often only requires welding work in difficult or dangerous assembly situations during assembly on the construction site, which must be avoided.

Bei angeschraubten Tragelementen ergibt sich hingegen bei den heute bekannten Systemen als wesentlicher Nachteil, dass die Tragfähigkeit und die Lagegenauigkeit unter Last deutlich hinter der von angeschweissten Tragelementen zurückstehen.In the case of screwed-on support elements, on the other hand, the main disadvantage of the systems known today is that the load-bearing capacity and the positional accuracy stand significantly behind that of welded support elements under load.

WO 99/58781 A1 offenbart eine Fassadenkonstruktion mit einer Pfosten-Riegel-Tragstruktur aus T-förmigen Metallprofilen, bei welcher klotzartige Tragelemente mit Befestigungsschrauben an Befestigungsprofilschienen befestigt sind, welche wiederum an den Riegelprofilen der Fassadenkonstruktion befestigt sind. Dabei sind die Befestigungsschrauben in nach aussen offenen Nuten der Befestigungsprofilschienen befestigt. Sie treten dabei durch eine die Befestigungsprofilschiene überdeckende Dichtung hindurch, an welcher die Tragelemente anliegen. Abgesehen davon, dass es, insbesondere im Brandfall, zu einem Auseinanderbiegen der Begrenzungen der Nuten der Befestigungsprofilschienen kommen kann, was zu einem totalen Versagen der Tragelemente führen würde, weist die hier gezeigte Befestigungssituation den Nachteil auf, dass die Steifigkeit der Anbindung der Tragelemente relativ gering ist und sich die Tragelemente schon bei relativ geringer Traglast deutlich nach unten neigen bzw. je Tragelement bei Einhaltung vertretbarer Neigungen nur geringe Traglasten realisiert werden können. WO 99/58781 A1 discloses a facade construction with a post-and-rail support structure made of T-shaped metal profiles, in which block-like support elements are fastened with fastening screws to fastening profile rails, which in turn are fastened to the transom profiles of the facade construction. The fastening screws are fastened in outwardly open grooves in the fastening profile rails. They pass through a seal that covers the fastening profile rail and against which the support elements rest. Apart from the fact that, especially in the event of a fire, the boundaries of the grooves of the fastening profile rails can bend apart, which would lead to a total failure of the support elements, the fastening situation shown here has the disadvantage that the stiffness of the connection of the support elements is relatively low is and the support elements incline significantly downwards even with a relatively low load or only low loads can be realized per support element if acceptable inclinations are observed.

DE 196 06 906 A1 offenbart eine Fassadenkonstruktion mit einer Pfosten-Riegel-Tragstruktur aus Metallhohlprofilen, bei welcher kreuzförmige Tragelemente jeweils im Kreuzungsbereich der Pfosten- und Riegelprofile mit Befestigungsschrauben an den Profilen angeschraubt sind. Dabei durchdringen die Befestigungsschrauben auf den Profilen angeordnete Dichtungen, an welchen die Tragelemente anliegen. Die hier gezeigte Befestigung der Tragelemente ist zwar deutlich stabiler als die zuvor beschriebene, sie weist jedoch den Nachteil auf, dass auf die gezeigte Weise nur im Kreuzungsbereich der Pfosten- und Riegelprofile Tragelemente bereitgestellt werden können. DE 196 06 906 A1 discloses a facade construction with a mullion-transom support structure made of hollow metal profiles, in which cross-shaped support elements are screwed to the profiles with fastening screws in the intersection area of the mullion and transom profiles. The fastening screws penetrate seals arranged on the profiles against which the support elements are in contact. The fastening of the support elements shown here is clearly more stable than the one described above, but it has the disadvantage that support elements can only be provided in the manner shown in the intersection area of the post and transom profiles.

Es stellt sich deshalb die Aufgabe, technische Lösungen zur Verfügung zu stellen, welche die zuvor genannten Nachteile des Standes der Technik nicht aufweisen oder zumindest teilweise vermeiden.The object is therefore to provide technical solutions which do not have the aforementioned disadvantages of the prior art or at least partially avoid them.

Diese Aufgabe wird durch die Gegenstände der unabhängigen Patentansprüche gelöst.This object is achieved by the subjects of the independent claims.

Gemäss diesen betrifft ein erster Aspekt der Erfindung eine Tragstruktur für Fassadenelemente.According to these, a first aspect of the invention relates to a support structure for facade elements.

Diese umfasst einen Tragriegel aus einem Metallprofilmaterial sowie ein von dem Tragriegel in horizontaler Richtung wegstehendes Tragelement für ein Fassadenelement. Das Tragelement ist an einem sich im Querschnitt gesehen im Wesentlichen vertikal erstreckenden Befestigungsprofilabschnitt des Tragriegels befestigt. Eine Dichtung erstreckt sich über den gesamten zwischen dem Befestigungsprofilabschnitt des Tragriegels und dem Tragelement gebildeten Angrenzungsbereich, welche einen Eintritt von Wasser in diesen Bereich verhindert. Im unteren Bereich dieses Angrenzungsbereichs stützt sich das Tragelement an mehreren Stellen über Stützelemente (anspruchsgemässe erste Stützelemente) an dem Befestigungsprofilabschnitt des Tragriegels ab, welche innerhalb der Dichtung angeordnet sind oder von aussen in die Dichtung eindringen bzw. diese durchdringen.This comprises a support bar made of a metal profile material and a support element for a facade element projecting away from the support bar in the horizontal direction. The support element is fastened to a fastening profile section of the support bar that extends essentially vertically when viewed in cross section. A seal extends over the entire adjacent area formed between the fastening profile section of the support bar and the support element, which prevents water from entering this area. In the lower area of this adjoining area, the support element is supported at several points via support elements (first support elements according to the claims) on the fastening profile section of the support bar, which are arranged within the seal or penetrate into or penetrate the seal from the outside.

Durch diese konstruktive Ausgestaltung stützt sich das Tragelement im unteren Bereich seines Angrenzungsbereichs (abgesehen von seiner abdichtenden Angrenzung an die Dichtung) praktisch nicht auf der Dichtung ab, sondern direkt auf dem Befestigungsprofilabschnitt des Tragriegels oder auf einem sehr dünnen Bereich aus Dichtungsmaterial, was zu einer hohen Steifigkeit der Anbindung der Tragelemente an den Tragriegel gegen ein Neigen in Traglastrichtung führt, so dass sich die Tragelemente unter üblichen Traglasten praktisch nicht nach unten neigen bzw. je Tragelement bei Einhaltung vertretbarer Neigungen sehr grosse Traglasten realisiert werden können.As a result of this structural design, the support element is supported in the lower area of its adjoining area (apart from its sealing abutment with the seal) practically not on the seal, but directly on the fastening profile section of the support bar or on a very thin area made of sealing material, which leads to a high Rigidity of the connection of the support elements to the support bar leads to tilting in the direction of the load, so that the support elements practically do not incline downwards under normal loads or, if adhered to, it is more acceptable for each support element Slopes very large loads can be realized.

In einer bevorzugten Ausführungsform der Tragstruktur stützt sich das Tragelement auch im oberen Bereich des zwischen dem Befestigungsprofilabschnitt des Tragriegels und dem Tragelement gebildeten Angrenzungsbereichs an mehreren Stellen über Stützelemente (anspruchsgemässe zweite Stützelemente) an dem Befestigungsprofilabschnitt des Tragriegels ab, welche innerhalb der Dichtung angeordnet sind oder von aussen in die Dichtung eindringen bzw. diese durchdringen.In a preferred embodiment of the support structure, the support element is also supported in the upper area of the adjoining area formed between the fastening profile section of the support bar and the support element at several points via support elements (second support elements according to the claims) on the fastening profile section of the support bar, which are arranged within the seal or from penetrate the outside of the seal or penetrate it.

Durch diese konstruktive Ausgestaltung stützt sich das Tragelement sowohl im unteren als auch im oberen Bereich seines Angrenzungsbereichs (abgesehen von seiner abdichtenden Angrenzung an die Dichtung) praktisch nicht auf der Dichtung ab, sondern direkt auf dem Befestigungsprofilabschnitt des Tragriegels oder auf einem sehr dünnen Bereich aus Dichtungsmaterial, was zu einer hohen Steifigkeit der Anbindung der Tragelemente an den Tragriegel gegen ein Neigen sowohl in als auch entgegen der Traglastrichtung führt. Hierdurch ergibt sich neben dem zuvor erwähnten Vorteil zusätzlich der Vorteil, dass das Tragelement bei der Montage im Wesentlichen unabhängig von der Anpresskraft eine genau definierte Relativposition bezüglich des Befestigungsprofilabschnitts einnimmt.As a result of this structural design, the support element is practically not supported on the seal in the lower as well as in the upper area of its adjoining area (apart from its sealing abutment with the seal), but directly on the fastening profile section of the support bar or on a very thin area made of sealing material , which leads to a high rigidity of the connection of the support elements to the support bar against tilting both in and against the load direction. In addition to the previously mentioned advantage, this results in the additional advantage that the support element assumes a precisely defined relative position with respect to the fastening profile section during assembly, essentially independently of the contact pressure.

Mit Vorteil ist das Tragelement mittels mehrerer Befestigungsschrauben an dem Befestigungsprofilabschnitt des Tragriegels befestigt, welche im Querschnitt gesehen oberhalb der anspruchsgemässen ersten Stützelemente und, falls vorhanden, zudem unterhalb der anspruchsgemässen zweiten Stützelemente in den Befestigungsprofilabschnitt eindringen, und zwar bevorzugterweise im Wesentlichen in horizontaler Richtung. Auf diese Weise lässt sich eine einfache und sichere Befestigung des Tragelements an dem Befestigungsprofilabschnitt des Tragriegels realisieren.Advantageously, the support element is fastened to the fastening profile section of the support bar by means of several fastening screws which, viewed in cross section, penetrate the fastening profile section above the first support elements according to the claims and, if present, also below the second support elements according to the claims, preferably essentially in the horizontal direction. In this way, the support element can be easily and securely fastened to the fastening profile section of the support bar.

Die Dichtung ist bevorzugterweise derartig ausgebildet, dass sie sich vor der Montage des Tragelements geschlossen über den Befestigungsprofilabschnitt des Tragriegels erstreckt und bei der Montage des Tragelements von den Stützelementen und/oder, falls vorhanden, von den Befestigungsschrauben durchdrungen wird. Auf diese Weise kann erreicht werden, dass die Dichtung nur an den Abstütz- und Befestigungsorten durchdrungen wird und sich an diesen Orten dicht an die Stützelemente und/- oder Befestigungsschrauben anlegt.The seal is preferably designed in such a way that it extends in a closed manner over the fastening profile section of the support bar before the assembly of the support element and is penetrated by the support elements and / or, if present, by the fastening screws during assembly of the support element. In this way, it can be achieved that the seal is only penetrated at the support and fastening locations and lies tightly against the support elements and / or fastening screws at these locations.

Weiter ist die Dichtung bevorzugterweise derartig ausgebildet, dass sie sich im Querschnitt gesehen in einen Bereich oberhalb des Tragelements erstreckt, wo sie mit einer dem Tragriegel zugewandten inneren Dichtfläche an den Tragriegel angrenzt und eine der inneren Dichtfläche gegenüberliegende äussere Dichtfläche bereitstellt, zur abdichtenden Angrenzung eines von dem Tragelement zu tragenden oder getragenen Fassadenelements an den Tragriegel.Furthermore, the seal is preferably designed in such a way that, viewed in cross section, it extends into an area above the support element, where it adjoins the support bar with an inner sealing surface facing the support bar and provides an outer sealing surface opposite the inner sealing surface, for sealing adjoining one of the support element to be carried or carried facade element to the support bar.

Mit Vorteil erstreckt sich die Dichtung zudem im Querschnitt gesehen in einen Bereich unterhalb des Tragelements, wo sie in analoger Weise mit einer dem Tragriegel zugewandten inneren Dichtfläche an den Tragriegel angrenzt und eine dieser inneren Dichtfläche gegenüberliegende äussere Dichtfläche bereitstellt, zur abdichtenden Angrenzung eines unterhalb von dem Tragelement anzuordnenden oder angeordneten Fassadenelements an den Tragriegel.Advantageously, the seal also extends, viewed in cross section, into an area below the support element, where it adjoins the support bar in an analogous manner with an inner sealing surface facing the support bar and provides an outer sealing surface opposite this inner sealing surface, for the sealing abutment of one below the support bar Support element to be arranged or arranged facade element on the support bar.

Auf diese Weise lässt sich eine hervorragende Abdichtung zwischen den zu tragenden Fassadenelementen und der erfindungsgemässen Tragstruktur erreichen.In this way, an excellent seal can be achieved between the facade elements to be supported and the support structure according to the invention.

Die Stützelemente oder zumindest ein Teil der Stützelemente sind bei einer ersten bevorzugten Ausführungsform der Tragstruktur von dem Befestigungsprofilabschnitt des Tragriegels gebildet, z.B. in Form einer Vielzahl von nach aussen vorstehenden Körnerprägungen.In a first preferred embodiment of the support structure, the support elements or at least some of the support elements are formed by the fastening profile section of the support bar, for example in the form of a plurality of outwardly protruding grain embossings.

Alternativ oder ergänzend sind die Stützelemente oder zumindest ein Teil der Stützelemente bei einer zweiten bevorzugten Ausführungsform der Tragstruktur von dem Tragelement gebildet, z.B. in Form einer Vielzahl von nach aussen vorstehender zackenförmiger Vorsprünge.Alternatively or in addition, the support elements or at least some of the support elements in a second preferred embodiment of the support structure are formed by the support element, e.g. in the form of a plurality of outwardly protruding serrated projections.

Alternativ oder ergänzend sind die Stützelemente oder zumindest ein Teil der Stützelemente bei einer dritten bevorzugten Ausführungsform der Tragstruktur von einem oder mehreren separat von dem Tragriegel und von dem Tragelement ausgebildeten Elementen gebildet, z.B. von einem oder mehreren auf das Tragelement aufgesteckten oder daran angeordneten Blechelementen, welche scharfkantige Stützvorsprünge bilden, oder von einer Vielzahl von in der Dichtung bereitgestellten Stützkörpern, z.B. in Form von Stahlkugeln oder Stahlstiften.As an alternative or in addition, the support elements or at least some of the support elements in a third preferred embodiment of the support structure are formed by one or more elements formed separately from the support bar and from the support element, for example one or more sheet metal elements attached to or arranged on the support element, which Form sharp-edged support projections, or from a large number of support bodies provided in the seal, for example in the form of steel balls or steel pins.

Je nach Ausgestaltung und Anwendungsfall kann die eine oder die andere Ausführungsform oder auch eine Kombination von diesen Ausführungsformen besonders vorteilhaft sein.Depending on the configuration and application, one or the other embodiment or also a combination of these embodiments can be particularly advantageous.

Weiter ist es bevorzugt, dass das Tragelement im Querschnitt gesehen mit einem daran gebildeten Vorsprung auf einer Profilschulter des Tragriegels aufliegt, derart, dass dadurch ein Formschluss zwischen dem Tragelement und dem Tragriegel in Schwerkraftrichtung gebildet wird. Die Dichtung erstreckt sich dabei mit Vorteil zwischen dem Vorsprung und der Profilschulter hindurch. Durch diese Ausgestaltung lässt sich die Montage des Tragelements vereinfachen, da dieses durch Anschlagen des Vorsprungs an die Profilschulter auf einfache Weise in seiner Befestigungsposition am Tragriegel anzuordnen ist. Auch lässt sich hierdurch die Sicherheit gegen ein Versagen des Tragelements erhöhen, und dies auch bei Ausführungsformen der Tragstruktur, bei denen sich die Dichtung bis in den Bereich oberhalb des Tragelements erstreckt.It is further preferred that the support element, viewed in cross section, rests with a projection formed thereon on a profile shoulder of the support bar in such a way that a form fit is thereby formed between the support element and the support bar in the direction of gravity. The seal advantageously extends through between the projection and the profile shoulder. This configuration makes it possible to simplify the assembly of the support element, since it can be arranged in its fastening position on the support bar in a simple manner by striking the projection against the profile shoulder. This also makes it possible to increase the security against failure of the support element, and this also in the case of embodiments of the support structure in which the seal extends into the area above the support element.

Der Befestigungsprofilabschnitt wird bevorzugterweise von einer horizontal vorspringenden Profilkontur des Tragriegels gebildet, mit Vorteil derart, dass diese Profilkontur im Querschnitt gesehen von zwei sich mit einem Abstand zueinander erstreckenden Profilbereichen (anspruchsgemässe erste Profilbereichen) gebildet ist, welche an ihren dem Tragriegel abgewandten Enden über einen sich im Wesentlichen vertikal erstreckenden Profilbereich (anspruchsgemässer zweiter Profilbereich) miteinander verbunden sind. Dieser anspruchsgemässe zweite Profilbereich stellt dabei den Befestigungsprofilabschnitt des Tragriegels dar.The fastening profile section is preferably made up of a horizontally projecting profile contour of the support bar, advantageously such that this profile contour, seen in cross section, is formed by two profile areas extending at a distance from one another (first profile areas according to the claims), which at their ends facing away from the support bar over a substantially vertically extending profile area (second profile area according to claim ) are connected to each other. This second profile area according to the claims represents the fastening profile section of the support bolt.

Dabei ist es weiter bevorzugt, dass der anspruchsgemässe zweite Profilbereich, welcher den Befestigungsprofilabschnitt des Tragriegels darstellt, eine Vielzahl von mit Vorteil identischen Öffnungen aufweist, welche in Längsrichtung der Befestigungsprofilabschnitts gesehen mit einem regelmässigen Abstand oder gemäss einem regelmässig wiederkehrenden Abstandsmuster hintereinander angeordnet sind. Dabei ist das Tragelement mit in diese Öffnungen eingeschraubten Befestigungsschrauben, welche bevorzugterweise als Blechschrauben ausgebildet sind, an dem Befestigungsprofilabschnitt befestigt.It is further preferred that the claimed second profile area, which represents the fastening profile section of the support bar, has a plurality of advantageously identical openings which, viewed in the longitudinal direction of the fastening profile section, are arranged with a regular spacing or according to a regularly recurring spacing pattern one behind the other. In this case, the support element is fastened to the fastening profile section with fastening screws screwed into these openings, which are preferably designed as sheet metal screws.

Durch diese Ausgestaltungen wird es möglich, den Befestigungsprofilabschnitt des Tragriegels mittels einer Befestigungsprofilschiene zur Verfügung zu stellen, welche zwecks Bildung des anspruchsgemässen Tragriegels an einem die eigentliche Tragstruktur des Riegels bildenden Tragprofil befestigt wird, z.B. mittels Verschweissen. Hierdurch können als Tragprofil kostengünstige Normprofile mit den jeweiligen aus statischen Gründen erforderlichen Abmessungen verwendet werden, an denen jeweils immer die gleichen Befestigungsprofilschienen befestigt werden.These configurations make it possible to provide the fastening profile section of the support bar by means of a fastening profile rail which, for the purpose of forming the support bar according to the claim, is fastened to a support profile forming the actual support structure of the bar, e.g. by welding. In this way, inexpensive standard profiles with the respective dimensions required for static reasons can be used as the support profile, to which the same mounting profile rails are always attached.

Entsprechend ist bei einer weiteren bevorzugten Ausführungsform der Tragstruktur der anspruchsgemässe Tragriegel von einem Tragprofil und einer daran befestigten Befestigungsprofilschiene gebildet oder umfasst diese Elemente.Correspondingly, in a further preferred embodiment of the support structure, the support bar according to the claims is formed by a support profile and a fastening profile rail attached to it or comprises these elements.

Die Befestigungsprofilschiene umfasst zwei sich parallel zueinander entlang ihrer Längskanten erstreckende und im Wesentlichen in einer gemeinsamen Ebene liegende Befestigungsflanschpartien zur Befestigung der Befestigungsprofilschiene an einer ebenen vertikalen Befestigungsfläche des Tragprofils. Diese Befestigungsflanschpartien sind über einen zwischen ihnen angeordneten und aus ihrer gemeinsamen Ebene hervorstehenden Verbindungssteg miteinander verbunden.The fastening profile rail comprises two fastening flange parts, which extend parallel to one another along their longitudinal edges and lie essentially in a common plane, for fastening the fastening profile rail to a flat vertical fastening surface of the support profile. These fastening flange parts are connected to one another via a connecting web which is arranged between them and protrudes from their common plane.

Der Verbindungssteg ist im Querschnitt gesehen von zwei sich mit einem Abstand zueinander und jeweils ausgehend von einer der beiden Befestigungsflanschpartien aus der gemeinsamen Ebene der Befestigungsflanschpartien heraus erstreckenden ersten Profilbereichen gebildet, welche an ihren der jeweiligen Befestigungsflanschpartie abgewandten Enden über einen sich im Wesentlichen parallel zu der gemeinsamen Ebene der Befestigungsflanschpartien erstreckenden zweiten Profilbereich miteinander verbunden sind, welcher den Befestigungsprofilabschnitt des Tragriegels bildet.The connecting web, seen in cross section, is formed by two first profile areas which extend at a distance from one another and each starting from one of the two fastening flange parts out of the common plane of the fastening flange parts Level of the fastening flange parts extending second profile area are connected to each other, which forms the fastening profile section of the support bolt.

Der zweite Profilbereich weist eine Vielzahl in Längsrichtung der Befestigungsprofilschiene gesehen mit einem regelmässigen Abstand oder gemäss einem regelmässig wiederkehrenden Abstandsmuster hintereinander angeordneter, insbesondere identischer Öffnungen auf, zur Befestigung der Tragelemente an der Befestigungsprofilschiene mittels Befestigungsschrauben, insbesondere mittels Blechschrauben, derart, dass die Begrenzungen der Öffnungen mit dem Schraubengewinde in Eingriff stehen.The second profile area has a large number of openings, in particular identical openings, arranged one behind the other, viewed in the longitudinal direction of the fastening rail, with a regular spacing or according to a regularly recurring spacing pattern, for fastening the support elements to the fastening rail by means of fastening screws, in particular by means of self-tapping screws, in such a way that the boundaries of the openings engage with the screw thread.

Die Öffnungen sind mit Vorteil als kreisrunde Löcher und/oder als Langlöcher ausgebildet, können aber auch jede andere Form aufweisen welche geeignet ist zum Befestigen von Schrauben durch Eingriff von Begrenzungen der Öffnungen in das Schraubengewinde. Zudem können die Begrenzungen der Öffnungen auch als zum Schraubengewinde komplementäres Innengewinde ausgebildet sein.The openings are advantageously designed as circular holes and / or as elongated holes, but can also have any other shape which is suitable for fastening screws by engaging the boundaries of the openings in the screw thread. In addition, the boundaries of the openings can also be designed as an internal thread complementary to the screw thread.

Weist die Befestigungsprofilschiene einen offenen Profilquerschnitt auf, was bevorzugt ist, so werden besonders kostengünstige Lösungen möglich, insbesondere dann, wenn die Befestigungsprofilschiene als gewalztes Metallprofil ausgebildet wird, was bevorzugt ist. Als Material eignet sich dabei besonders Stahl oder Edelstahl.If the fastening profile rail has an open profile cross-section, which is preferred, then particularly cost-effective solutions are possible, in particular if the fastening profile rail is designed as a rolled metal profile, which is preferred. Steel or stainless steel are particularly suitable as the material.

In einer bevorzugten Ausführungsform der Befestigungsprofilschiene ist der zweite Profilbereich des Verbindungsstegs an seinen Längsseiten von Randbereichen begrenzt, welche sich über die gesamte Längserstreckung der Befestigungsprofilschiene erstreckenden und in einer Richtung wegzeigend von den Befestigungsflanschpartien über die Öffnungen vorstehen.In a preferred embodiment of the mounting profile rail, the second profile area of the connecting web is delimited on its longitudinal sides by edge areas which extend over the entire length of the mounting profile rail and protrude in one direction from the mounting flange parts over the openings.

Insbesondere für den bevorzugten Fall, dass die vorstehenden Randbereiche die Öffnungen an den Längsseiten des zweiten Profilabschnitts begrenzen, ergibt sich hierdurch eine deutliche Montageerleichterung, weil die Befestigungsschrauben bei der Montage durch die vorstehenden Randbereiche bezüglich der Öffnungen zentriert werden und so beim Rotieren in Einschraubrichtung automatisch die nächstgelegene Öffnung finden.In particular for the preferred case that the protruding edge areas limit the openings on the long sides of the second profile section, this results in a significant simplification of assembly, because the fastening screws are centered with respect to the openings during assembly by the protruding edge areas and so automatically when rotating in the screwing direction find the nearest opening.

Dabei ist es für den Fall, dass die Befestigungsprofilschiene als gewalztes Metallprofil ausgebildet ist, bevorzugt, dass die vorstehenden Randbereiche von Blechdoppelungen gebildet sind. In einer bevorzugten Variante sind die Randbereiche von V-förmig ausgerichteten Blechdoppelungen gebildet, welche bei der Montage auch einer Positionierung der Befestigungsschrauben dienen.In this case, in the event that the fastening profile rail is designed as a rolled metal profile, it is preferred that the protruding edge regions are formed by doubled sheet metal. In a preferred variant, the edge areas are formed by sheet metal doubles which are aligned in a V-shape and which also serve to position the fastening screws during assembly.

In einer weiteren bevorzugten Ausführungsform der Befestigungsprofilschiene verringert sich der Abstand zwischen den ersten Profilbereichen des Verbindungsstegs im Querschnitt der Befestigungsprofilschiene gesehen in Richtung von dem zweiten Profilbereich zu der gemeinsamen Ebene der Befestigungsflanschpartien ausgehend von dem zweiten Profilbereich zuerst zunehmend und erweitert sich sodann ab einem Umkehrpunkt wieder zunehmend.In a further preferred embodiment of the fastening profile rail, the distance between the first profile areas of the connecting web, viewed in the cross-section of the fastening profile rail, decreases initially increasingly starting from the second profile area and then widens again increasingly from a reversal point .

Dieser Umkehrpunkt liegt bevorzugterweise etwa in der Mitte zwischen dem zweiten Profilbereich und der gemeinsamen Ebene der Befestigungsflanschpartien.This reversal point is preferably approximately in the middle between the second profile area and the common plane of the fastening flange parts.

Insbesondere für den bevorzugten Fall, dass dabei der Abstand zwischen den ersten Profilbereichen im Querschnitt der Befestigungsprofilschiene gesehen am Umkehrpunkt gleich gross oder kleiner ist als die Erstreckung der Öffnungen quer zur Profillängsrichtung der Befestigungsprofilschiene in einer Richtung parallel zur gemeinsamen Ebene der Befestigungsflanschpartien, ergibt sich der Vorteil, dass eine bis zum Umkehrpunkt in eine Öffnung des zweiten Profilbereichs eingeschraubte Befestigungsschraube am Umkehrpunkt zwischen den beiden ersten Profilbereichen radial geklemmt und dadurch stabilisiert wird. Auch wird hierdurch eine kraftschlüssige Sicherung gegen ein selbsttätiges Lösen der Befestigungsschrauben erreicht.In particular, for the preferred case that the distance between the first profile areas in the cross section of the mounting profile rail is the same size or smaller than the extent of the openings transversely to the longitudinal direction of the mounting profile rail in a direction parallel to the common plane of the mounting flange parts, there is the advantage that a fastening screw screwed into an opening of the second profile area up to the reversal point is clamped radially at the reversal point between the two first profile areas and thereby stabilized. In this way, a force-fit securing against automatic loosening of the fastening screws is also achieved.

In noch einer weiteren bevorzugten Ausführungsform werden die Längskanten der Befestigungsprofilschiene von im Querschnitt gesehen C-förmigen Profilbereichen gebildet. Dabei wird der erste Schenkel der C-Form von der jeweiligen sich entlang der jeweiligen Längskante der Befestigungsprofilschiene erstreckenden Befestigungsflanschpartie gebildet. Der zweite Schenkel der C-Form erstreckt sich entlang der Seite der jeweiligen Befestigungsflanschpartie, auf welcher sich der Verbindungssteg aus der gemeinsamen Ebene der Befestigungsflanschpartien heraus erstreckt, und zwar bevorzugterweise im Wesentlichen parallel zu dem ersten Schenkel der C-Form in Richtung auf den Verbindungssteg zu.In yet another preferred embodiment, the longitudinal edges of the fastening profile rail are formed by C-shaped profile areas when viewed in cross section. The first leg of the C-shape is formed by the respective fastening flange section extending along the respective longitudinal edge of the fastening profile rail. The second leg of the C-shape extends along the side of the respective fastening flange part on which the connecting web extends out of the common plane of the fastening flange parts, specifically preferably essentially parallel to the first limb of the C-shape in the direction of the connecting web .

Insbesondere für den bevorzugten Fall, dass die beiden Schenkel der C-Form zueinander beabstandet sind, ergibt sich der Vorteil, dass in dem so gebildeten Hinterschnitt Auflage- und/oder Dichtungsprofilabschnitte zur Angrenzung an die mit der Befestigungsprofilschiene zu befestigenden Fassadenelemente befestigt werden können.In particular for the preferred case that the two legs of the C-shape are spaced apart from one another, there is the advantage that support and / or sealing profile sections can be fastened in the undercut formed in this way to adjoin the facade elements to be fastened with the fastening profile rail.

In noch einer weiteren bevorzugten Ausführungsform weisen die Befestigungsflanschpartien der Befestigungsprofilschiene Durchbrüche auf, bevorzugterweise kreisrunde Löcher und/oder Langlöcher, mit denen die Befestigungsprofilschiene mittels Schrauben und/oder mittels im Bereich der Begrenzungen dieser Löcher angebrachten Schweissnähten an dem Tragprofil befestigt ist.In yet another preferred embodiment, the fastening flange parts of the fastening profile rail have openings, preferably circular holes and / or elongated holes, with which the fastening profile rail is fastened to the support profile by means of screws and / or by means of welds made in the area of the boundaries of these holes.

In noch einer weiteren bevorzugten Ausführungsform weisen die Befestigungsflanschpartien der Befestigungsprofilschiene auf ihrer an das Tragprofil angrenzenden Seite Vorsprünge auf, welche an einer ebenen Befestigungsfläche des Tragprofils anliegen und einen definierten Abstand zwischen der Befestigungsfläche und den übrigen Bereichen der Befestigungsflanschpartien sicherstellen. Hierdurch werden Hinterlüftungsräume geschaffen, welche eine Ansammlung von Wasser zwischen der Befestigungsprofilschiene und der Fassadenkonstruktion verhindern.In yet another preferred embodiment, the fastening flange parts of the fastening profile rail have projections on their side adjacent to the support profile, which rest against a flat fastening surface of the support profile and ensure a defined distance between the fastening surface and the other areas of the fastening flange parts. This creates ventilation spaces that prevent water from accumulating between the fastening profile rail and the facade structure.

Ein zweiter Aspekt der Erfindung betrifft eine Gebäudefassade umfassend eine Tragstruktur gemäss dem ersten Aspekt der Erfindung zum Tragen von Fassadenelementen der Gebäudefassade. Diese Fassadenelemente sind bevorzugterweise Glas-Fassadenelemente. Bei derartigen Gebäudefassaden treten die Vorteile der Erfindung besonders deutlich zu Tage.A second aspect of the invention relates to a building facade comprising a support structure according to the first aspect of the invention for supporting facade elements of the building facade. These facade elements are preferably glass facade elements. In such building facades, the advantages of the invention are particularly evident.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Die Figuren 1 und 2 zeigen Vertikalschnitte durch einen Teil einer erfindungsgemässen, in Pfosten-Riegel-Bauweise erstellten Gebäude-Glasfassade im Bereich eines Tragriegels 1, 20 der erfindungsgemässen Tragstruktur 2 der Gebäudefassade. Die Schnittlegung verläuft bei Fig. 1 durch eines der Tragelemente 22, von denen die gläsernen Fassadenelemente 4 getragen werden, und bei Fig. 2 zwischen zwei an dem dargestellten Tragriegel 1, 20 befestigten Tragelementen 22.the Figures 1 and 2 show vertical sections through part of a post-and-rail construction according to the invention created building glass facade in the area of a support bar 1, 20 of the inventive support structure 2 of the building facade. The cut runs at Fig. 1 by one of the support elements 22, by which the glass facade elements 4 are supported, and at Fig. 2 between two support elements 22 fastened to the illustrated support bar 1, 20.

Wie zu erkennen ist, sind die Tragriegel 1, 20 der Tragstruktur 2 jeweils aus einem Tragprofil 20 aus einem rechteckigen Stahlrohr und einer daran befestigten Befestigungsprofilschiene 1 aus einem gewalzten Stahlprofil gebildet. Die Befestigungsprofilschiene 1 ist durch Verschweissen in regelmässigen Abständen auf einer ebenen vertikalen Befestigungsfläche 6 des Tragprofils 20 befestigt.As can be seen, the support bars 1, 20 of the support structure 2 are each formed from a support profile 20 from a rectangular steel tube and a fastening profile rail 1 from a rolled steel profile attached to it. The fastening profile rail 1 is fastened by welding at regular intervals on a flat vertical fastening surface 6 of the support profile 20.

Die Tragelemente 22 sind aus Aluminium-Vollprofilmaterial gefertigt. Auf ihrer der Befestigungsprofilschiene 1 zugewandten Seite ist jeweils ein Blechstreifen 30 aus Edelstahl angeordnet, welcher entlang seiner unteren Begrenzung mit mehreren Körnerprägungen 31 versehen ist, die auf der der Befestigungsprofilschiene 1 zugewandten Seite des Blechstreifens 30 als kegelspitzförmige Vorsprünge 25 hervorstehen. Sie sind jeweils mittels vier Befestigungsschrauben 11 an der jeweiligen Befestigungsprofilschiene 1 befestigt.The support elements 22 are made of solid aluminum profile material. On the side facing the fastening profile rail 1, a sheet metal strip 30 made of stainless steel is arranged, which is provided along its lower boundary with several grain embossings 31, which protrude as cone-shaped projections 25 on the side of the sheet metal strip 30 facing the fastening profile rail 1. They are each fastened to the respective fastening profile rail 1 by means of four fastening screws 11.

Die Fassadenelemente 4 sind mittels Distanzplatten 28 auf den Tragelementen 22 gelagert und werden durch Halteprofilschienen 3 an der Tragstruktur 2 gesichert, welche ebenfalls mittels Befestigungsschrauben 11 an den Befestigungsprofilschienen 1 befestigt sind.The facade elements 4 are mounted on the support elements 22 by means of spacer plates 28 and are secured to the support structure 2 by holding profile rails 3, which are also fastened to the fastening profile rails 1 by means of fastening screws 11.

Wie weiter zu erkennen ist, sind zwischen den Fassadenelementen 4 und den Befestigungsprofilschienen 1 und zwischen den Fassadenelementen 4 und den Halteprofilschienen 3 Dichtungen 21, 29 angeordnet. Die Halteprofilschienen 3 pressen die Fassadenelemente 4 unter einer von den Befestigungsschrauben 11 erzeugten Druckkraft gegen die Dichtungen 21, 29, unter elastischer Deformation derselben.As can also be seen, seals 21, 29 are arranged between the facade elements 4 and the fastening profile rails 1 and between the facade elements 4 and the holding profile rails 3. The holding profile rails 3 press the facade elements 4 against it under a compressive force generated by the fastening screws 11 the seals 21, 29, with elastic deformation of the same.

Die fassadenseitigen Dichtungen 21 zwischen den Fassadenelementen 4 und den Befestigungsprofilschienen 1 erstrecken sich jeweils über die gesamte Befestigungsprofilschiene 1, und damit jeweils nicht nur über die jeweiligen zwischen den Tragelementen 22 und den Befestigungsprofilschienen 1 gebildeten Angrenzungsbereiche sondern auch über Bereiche die ober- und unterhalb des jeweiligen Tragelements 22 liegen. In diesen letztgenannten Bereichen grenzen die Dichtungen 21 jeweils mit einer der Befestigungsprofilschiene 1 zugewandten inneren Dichtfläche 26 an die Befestigungsprofilschiene 1 an und stellen jeweils eine dieser inneren Dichtfläche 26 gegenüberliegende äussere Dichtfläche 27 bereit. Im oberhalb des Tragelements 22 liegenden Bereich dient diese Dichtfläche 27 der abdichtenden Angrenzung des von dem jeweiligen Tragelement 22 getragenen Fassadenelements 4 an den Tragriegel 1, 20, im unterhalb des Tragelements 22 liegenden Bereich dient diese Dichtfläche 27 der abdichtenden Angrenzung des unterhalb von dem Tragelement 22 angeordneten Fassadenelements 4 an den Tragriegel 1, 20.The facade-side seals 21 between the facade elements 4 and the fastening profile rails 1 each extend over the entire fastening profile rail 1, and thus in each case not only over the respective adjacent areas formed between the support elements 22 and the fastening profile rails 1 but also over areas above and below the respective Support element 22 lie. In these last-mentioned areas, the seals 21 each adjoin the fastening profile rail 1 with an inner sealing surface 26 facing the fastening profile rail 1 and each provide an outer sealing surface 27 opposite this inner sealing surface 26. In the area above the support element 22, this sealing surface 27 serves to seal the adjoining of the facade element 4 carried by the respective support element 22 to the support bar 1, 20; arranged facade element 4 on the support bar 1, 20.

In den zwischen den Tragelementen 22 und den Befestigungsprofilschienen 1 gebildeten Angrenzungsbereichen werden die Dichtungen 21 jeweils punktuell von den Befestigungsschrauben 11 für die Tragelemente 22 und die Halteprofilschienen 3 durchdrungen.In the adjoining areas formed between the support elements 22 and the fastening profile rails 1, the seals 21 are each punctually penetrated by the fastening screws 11 for the support elements 22 and the holding profile rails 3.

Auch die kegelspitzförmige Vorsprünge 25 der Tragelemente 22 durchdringen die fassadenseitigen Dichtungen 21 punktuell, so dass ihre Spitzen auf der jeweiligen Befestigungsprofilschiene 1 aufliegen und sich die Tragelemente 22 jeweils im unteren Bereich ihres Angrenzungsbereichs nicht an der Dichtung 21 abstützen, sondern über diese Vorsprünge 25 an mehreren Stellen an der jeweiligen Befestigungsprofilschiene 1.The cone-shaped projections 25 of the support elements 22 also penetrate the facade-side seals 21 at points, so that their tips rest on the respective fastening profile rail 1 and the support elements 22 are not supported on the seal 21 in the lower area of their adjoining area, but on several of these projections 25 Positions on the respective mounting rail 1.

Fig. 3 zeigt eine perspektivische Ansicht der Befestigungsprofilschiene 1 eines der Tragriegel 1, 20. Fig. 3 shows a perspective view of the fastening profile rail 1 of one of the support bars 1, 20.

Die Befestigungsprofilschiene 1 umfasst zwei sich parallel zueinander entlang ihrer Längskanten erstreckende und im Wesentlichen in einer gemeinsamen Ebene liegende Befestigungsflanschpartien 5a, 5b, welche der Befestigung der Befestigungsprofilschiene 1 an der ebenen Befestigungsfläche 6 des Tragprofils 20 dienen.The fastening profile rail 1 comprises two fastening flange parts 5a, 5b which extend parallel to one another along their longitudinal edges and lie essentially in a common plane, which are used to fasten the fastening profile rail 1 to the flat fastening surface 6 of the support profile 20.

Die Befestigungsflanschpartien 5a, 5b der Befestigungsprofilschiene 1 sind über einen zwischen diesen angeordneten und aus der gemeinsamen Ebene der Befestigungsflanschpartien 5a, 5b hervorstehenden Verbindungssteg 7 miteinander verbunden.The fastening flange parts 5a, 5b of the fastening profile rail 1 are connected to one another via a connecting web 7 arranged between them and protruding from the common plane of the fastening flange parts 5a, 5b.

Dieser Verbindungssteg 7 wird im Querschnitt gesehen von zwei sich mit einem Abstand zueinander und jeweils ausgehend von einer der beiden Befestigungsflanschpartien 5a, 5b aus der gemeinsamen Ebene der Befestigungsflanschpartien 5a, 5b heraus erstreckenden ersten Profilbereichen 8a, 8b gebildet, die an ihren der jeweiligen Befestigungsflanschpartie 5a, 5b abgewandten Enden über einen sich im Wesentlichen parallel zu der gemeinsamen Ebene der Befestigungsflanschpartien 5a, 5b erstreckenden zweiten Profilbereich 9 miteinander verbunden sind.This connecting web 7, seen in cross section, is formed by two first profile areas 8a, 8b which extend at a distance from one another and each starting from one of the two fastening flange parts 5a, 5b out of the common plane of the fastening flange parts 5a, 5b and which at their respective fastening flange parts 5a , 5b facing away from ends via a substantially parallel to the common plane of the fastening flange parts 5a, 5b extending second profile area 9 are connected to each other.

Der zweite Profilbereich 9 des Verbindungsstegs 7 bildet bei den Befestigungsprofilschienen 1 jeweils den anspruchsgemässen Befestigungsprofilabschnitt 9. Er weist eine Vielzahl von in Längsrichtung der Befestigungsprofilschiene 1 gesehen mit einem regelmässigen Abstand hintereinander angeordneten identischen kreisrunden Bohrungen 10 auf, welche der Aufnahme und Verankerung der Befestigungsschrauben 11 für die Befestigung der Tragelemente 22 und der Halteprofilschienen 3 an der Befestigungsprofilschiene 1 dienen. Die Befestigungsschrauben 11 dabei mit einem Gewinde in die jeweilige Bohrung 10 eingeschraubt, so dass über das Gewinde eine formschlüssige Verbindung mit den Begrenzungen der Bohrungen 10 in und entgegen der Einschraubrichtung entsteht.The second profile area 9 of the connecting web 7 forms the fastening profile section 9 according to the claims in the fastening profile rails 1 the fastening of the support elements 22 and the holding profile rails 3 on the fastening profile rail 1 are used. The fastening screws 11 are screwed into the respective bore 10 with a thread, so that a form-fitting connection with the boundaries of the bores 10 in and against the screwing-in direction is created via the thread.

Wie weiter in Fig. 3 erkennbar ist, ist der zweite Profilbereich 9, welcher die Befestigungsbohrungen 10 bereitstellt, an seinen Längsseiten von sich über die gesamte Längserstreckung der Befestigungsprofilschiene 1 erstreckenden und über die Bohrungen 10 in einer Richtung wegzeigend von den Befestigungsflanschpartien 5a, 5b hervorstehenden Randbereichen 12a, 12b begrenzt, welche die Bohrungen 10 an den Längsseiten dieses Profilbereichs 9 im Wesentlichen begrenzen. Diese Randbereiche sind als Blechdoppelungen ausgebildet.As further in Fig. 3 As can be seen, the second profile area 9, which provides the fastening bores 10, is delimited on its longitudinal sides by edge areas 12a, 12b extending over the entire longitudinal extent of the fastening profile rail 1 and protruding over the bores 10 in a direction pointing away from the fastening flange parts 5a, 5b, which essentially delimit the bores 10 on the longitudinal sides of this profile area 9. These edge areas are designed as laminations of sheet metal.

Wie aus Fig. 3 in Zusammenschau mit Fig. 7 hervorgeht, welche einen Schnitt durch die Befestigungsprofilschiene 1 mit einer Befestigungsschraube 11 eingeschraubt in eine der Bohrungen 10 zeigt, verringert sich der Abstand zwischen den ersten Profilbereichen 8a, 8b im Querschnitt der Befestigungsprofilschiene 1 gesehen in Richtung von dem zweiten Profilbereich 9 zu der gemeinsamen Ebene der Befestigungsflanschpartien 5a, 5b gesehen ausgehend von dem zweiten Profilbereich 9 zuerst zunehmend und erweitert sich sodann ab einem Umkehrpunkt UP wieder zunehmend. Dabei befindet sich der Umkehrpunkt UP etwa in der Mitte zwischen dem zweiten Profilbereich 9 und der gemeinsamen Ebene der Befestigungsflanschpartien 5a, 5b.How out Fig. 3 in sync with Fig. 7 shows, which shows a section through the fastening profile rail 1 with a fastening screw 11 screwed into one of the bores 10, the distance between the first profile areas 8a, 8b in the cross section of the fastening profile rail 1, seen in the direction from the second profile area 9 to the common plane of the Fastening flange parts 5a, 5b, seen starting from the second profile area 9, initially increasing and then increasing again from a reversal point UP. The reversal point UP is located approximately in the middle between the second profile area 9 and the common plane of the fastening flange parts 5a, 5b.

Da der Abstand zwischen den ersten Profilbereichen 8a, 8b im Querschnitt der Befestigungsprofilschiene 1 gesehen am Umkehrpunkt UP gleich gross oder etwas kleiner ist als der Durchmesser der Öffnungen 10, wird die Befestigungsschraube 11 zwischen den beiden ersten Profilbereichen 8a, 8b unter federelastischer Deformation derselben eingeklemmt und dadurch stabilisiert und kraftschlüssig gegen ein Herausdrehen gesichert.Since the distance between the first profile areas 8a, 8b, seen in the cross section of the mounting profile rail 1 at the reversal point UP, is equal to or slightly smaller than the diameter of the openings 10, the mounting screw 11 is clamped between the two first profile areas 8a, 8b under elastic deformation of the same and thereby stabilized and positively secured against unscrewing.

Wie insbesondere aus Fig. 3 hervorgeht, werden die Längskanten der Befestigungsprofilschiene 1 von im Querschnitt gesehen C-förmigen Profilbereichen 13a, 13b gebildet, bei denen der erste Schenkel 14a, 14b der C-Form von der jeweiligen sich entlang der jeweiligen Längskante erstreckenden Befestigungsflanschpartie 5a, 5b gebildet wird. Der zweite Schenkel 15a, 15b der C-Form erstreckt sich jeweils parallel zum jeweiligen ersten Schenkel 14a bzw. 14 b auf der Seite der jeweiligen Befestigungsflanschpartie 5a, 5b, auf welcher der Verbindungssteg 7 sich aus der gemeinsamen Ebene der Befestigungsflanschpartien 5a, 5b heraus erstreckt, in Richtung auf den Verbindungssteg 7 zu. Dabei sind die beiden Schenkel 14a, 15a; 14b, 15b der C-Form jeweils zueinander beabstandet. In den so gebildeten Hinterschnitten ist die Dichtung 21 mit den die inneren Dichtflächen 26 bildenden Dichtungsprofilabschnitten befestigt (siehe Fig. 1).Like in particular from Fig. 3 As can be seen, the longitudinal edges of the fastening profile rail 1 are formed by C-shaped profile areas 13a, 13b when viewed in cross section, in which the first leg 14a, 14b of the C-shape extends along the respective Longitudinal edge extending fastening flange part 5a, 5b is formed. The second leg 15a, 15b of the C-shape extends parallel to the respective first leg 14a or 14b on the side of the respective fastening flange part 5a, 5b on which the connecting web 7 extends out of the common plane of the fastening flange parts 5a, 5b , in the direction of the connecting web 7 to. The two legs 14a, 15a; 14b, 15b of the C-shape are each spaced apart from one another. In the undercuts formed in this way, the seal 21 is fastened with the sealing profile sections forming the inner sealing surfaces 26 (see FIG Fig. 1 ).

Wie am besten aus den Figuren 4, 5 und 6 ersichtlich ist, welche eine Draufsicht auf die Befestigungsprofilschiene 1 (Fig. 4), einen Schnitt durch die Befestigungsprofilschiene 1 entlang der Linie A-A in Fig. 4 (Fig. 5) sowie einen Schnitt durch die Befestigungsprofilschiene entlang der Linie B-B in Fig. 4 (Fig. 6) zeigen, weisen die Befestigungsflanschpartien 5a, 5b der Befestigungsprofilschiene 1 Durchbrüche in Form von kreisrunden Löchern 16 und in Form von Langlöchern 17 auf, welche zum Befestigen derselben mittels Schrauben, Setzbolzen und/oder im Bereich der Begrenzungen dieser Löcher 16, 17 angebrachten Verschweissungen an dem Tragprofil 20 dienen.How best from the Figures 4 , 5 and 6 can be seen, which is a top view of the mounting profile rail 1 ( Fig. 4 ), a section through the mounting profile rail 1 along the line AA in Fig. 4 ( Fig. 5 ) and a section through the mounting profile rail along the line BB in Fig. 4 ( Fig. 6 ) show, the fastening flange parts 5a, 5b of the fastening profile rail 1 have openings in the form of circular holes 16 and in the form of elongated holes 17, which have welds made in the area of the boundaries of these holes 16, 17 for fastening the same by means of screws, set bolts and / or in the area of the boundaries of these holes 16, 17 serve the support profile 20.

Des Weiteren weisen die Befestigungsflanschpartien 5a, 5b jeweils auf ihrer an die Befestigungsfläche 6 des Tragprofils 20 angrenzenden Seite von langlochähnlichen Prägungen gebildete Vorsprünge 18 auf, welche an der Befestigungsfläche 6 anliegen und einen definierten Abstand zwischen der Befestigungsfläche 6 und den übrigen Bereichen der Befestigungsflanschpartien 5a, 5b sicherstellen.Furthermore, the fastening flange parts 5a, 5b each have on their side adjoining the fastening surface 6 of the support profile 20, projections 18 formed by elongated hole-like embossings, which bear against the fastening surface 6 and a defined distance between the fastening surface 6 and the other areas of the fastening flange parts 5a, 5b ensure.

Wie in Fig. 8, welche eine perspektivische Ansicht eines Abschnitts des Tragriegels 1, 20 zeigt, anhand der dort eingetragenen Pfeile verdeutlicht ist, wird auf diese Weise durch die Vorsprünge 18 und die Bohrungen 10 ein definierter Hinterlüftungsspalt zwischen dem Tragprofil 20 und der Befestigungsprofilschiene 1 geschaffen, welcher eine Ansammlung von Wasser in diesem Bereich sicher verhindert.As in Fig. 8 , which shows a perspective view of a section of the support bar 1, 20, is illustrated by the arrows entered there, is in this way by the projections 18 and the Bores 10 created a defined ventilation gap between the support profile 20 and the mounting profile rail 1, which reliably prevents the accumulation of water in this area.

Fig. 9 eine perspektivische Explosionszeichnung eines Abschnitts der Tragstruktur aus Fig. 1 mit den Tragstrukturkomponenten 1, 11, 20, 22. Fig. 9 an exploded perspective view of a portion of the support structure Fig. 1 with the supporting structure components 1, 11, 20, 22.

Wie zu erkennen ist, sind die Tragelemente 22 jeweils mittels vier in die Öffnungen 10 am zweiten Profilbereich 9 des Verbindungsstegs 7 eingeschraubten Befestigungsschrauben 11 an der jeweiligen Befestigungsprofilschiene 1 befestigt und bilden auf ihrer Oberseite jeweils eine ebene Auflagefläche 24 für die darauf aufzulegende Begrenzungskante des Fassadenelements 4 bzw. für die Distanzplatte 28 zur Auflage der Begrenzungskante des Fassadenelements 4.As can be seen, the support elements 22 are each fastened to the respective fastening profile rail 1 by means of four fastening screws 11 screwed into the openings 10 on the second profile area 9 of the connecting web 7 and each form a flat support surface 24 on their upper side for the boundary edge of the facade element 4 to be placed thereon or for the spacer plate 28 to support the boundary edge of the facade element 4.

Fig. 10 zeigt eine perspektivische Ansicht eines Abschnitts des Tragriegels 1, 20 mit der Dichtung 21 aus Fig. 1 aber mit einem anderen Tragelement 22 befestigt daran. Dieses Tragelement 22 ist zweiteilig aufgebaut. Es besteht aus einem Grundkörper 23, der mit Befestigungsschrauben 11 an der Befestigungsprofilschiene 1 befestigt ist, und einer Auflageplatte 32, welche mit dem Grundkörper 23 verbunden ist. Fig. 10 FIG. 11 shows a perspective view of a section of the support bar 1, 20 with the seal 21 from FIG Fig. 1 but with another support element 22 attached to it. This support element 22 is constructed in two parts. It consists of a base body 23, which is fastened to the fastening profile rail 1 with fastening screws 11, and a support plate 32 which is connected to the base body 23.

Die Figuren 11 und 12 zeigen perspektivische Ansichten zweier Varianten des Grundkörpers dieses zweiteiligen Tragelements 22 aus Fig. 10.the Figures 11 and 12 show perspective views of two variants of the base body of this two-part support element 22 from FIG Fig. 10 .

Bei der ersten in Fig. 11 gezeigten Variante besteht der Grundkörper 23 aus einem Abschnitt aus einem Aluminiumprofilmaterial, welches nach unten offene Bohrungen 33 zur Aufnahme der Befestigungsschrauben 11 aufweist. Auf seiner der Befestigungsprofilschiene 1 zugewandten Seite ist ein Blechstreifen 30 aus Edelstahl angeordnet, welcher mehrere sich durchgehend über die gesamte Höhe des Grundkörpers 23 erstreckende Faltungen 34 aufweist, die auf der der Befestigungsprofilschiene 1 zugewandten Seite des Blechstreifens 30 als scharfkantige Grate hervorstehen.The first in Fig. 11 As shown in the variant shown, the base body 23 consists of a section made of an aluminum profile material which has bores 33 which are open at the bottom for receiving the fastening screws 11. On its side facing the fastening profile rail 1, a sheet metal strip 30 made of stainless steel is arranged, which has several folds 34 extending continuously over the entire height of the base body 23, which on the fastening profile rail 1 facing side of the sheet metal strip 30 protrude as sharp-edged burrs.

Bei der zweiten Variante des Grundkörpers 23, welche in Fig. 12 gezeigt ist, ist der Grundkörper 23 aus dem gleichen Profilmaterial gefertigt wie bei der ersten Variante. Entsprechend weist auch er nach unten offene Bohrungen 33 zur Aufnahme der Befestigungsschrauben 11 auf. Im Unterschied zu dem Grundkörper gemäss Fig. 11 weist dieser Grundkörper 23 jedoch auf seiner der Befestigungsprofilschiene 1 zugewandten Seite im Bereich von derer unteren Begrenzung mehrere zackenförmige Vorsprünge 35 auf, welche durch Fräsbearbeitung dieser Seite des Grundkörpers 23 erzeugt wurden.In the second variant of the base body 23, which is shown in Fig. 12 is shown, the base body 23 is made of the same profile material as in the first variant. Correspondingly, it also has downwardly open bores 33 for receiving the fastening screws 11. In contrast to the basic body according to Fig. 11 however, this base body 23 has, on its side facing the fastening profile rail 1, in the area of its lower boundary, several jagged projections 35, which were produced by milling this side of the base body 23.

Die Figuren 14 bis 16 zeigen Vertikalschnitte durch die in Fig. 10 gezeigte Anordnung mit einem Tragelement 22 gebildet aus dem Grundkörper 23 mit Blechstreifen 30 aus Fig. 11, und zwar einmal mit Schnittlegung zwischen zwei Faltungen 34 des Blechstreifens 30 (Fig. 14 mit Detail A in Fig. 13) und einmal mit Schnittlegung durch die Spitze einer der Faltungen 34 (Fig. 16 mit Detail B in Fig. 15).the Figures 14 to 16 show vertical sections through the in Fig. 10 The arrangement shown with a support element 22 formed from the base body 23 with sheet metal strips 30 Fig. 11 , once with a cut between two folds 34 of the sheet metal strip 30 ( Fig. 14 with detail A in Fig. 13 ) and once with an incision through the tip of one of the folds 34 ( Fig. 16 with detail B in Fig. 15 ).

Wie insbesondere aus den Figuren 13 und 15 hervorgeht, durchstossen die Faltungen 34 des Blechstreifens 30 die Dichtung 21 linienförmig und liegen dadurch im oberen und unteren Angrenzungsbereich des Tragelements 22 direkt an den ober- und unterhalb der Befestigungsbohrungen 10 hervorstehenden Randbereichen 12a, 12b des Befestigungsprofilabschnitts 9 der Befestigungsprofilschiene 1 an (siehe Fig. 15), während der Blechstreifen 30 in den Bereichen zwischen den Faltungen 34 unter elastischer Deformation der Dichtung 21 an dieser anliegt (siehe Fig. 13).As in particular from the Figures 13 and 15th is shown, the folds 34 of the sheet metal strip 30 pierce the seal 21 linearly and are thereby in the upper and lower adjoining area of the support element 22 directly on the above and below the fastening bores 10 protruding edge areas 12a, 12b of the fastening profile section 9 of the mounting profile rail 1 (see Fig. 15 ), while the sheet metal strip 30 rests against the seal 21 in the areas between the folds 34 with elastic deformation of the seal 21 (see FIG Fig. 13 ).

Die Figuren 17 bis 20 zeigen Vertikalschnitte durch die in Fig. 10 gezeigte Anordnung mit einem Tragelement 22 gebildet dem Grundkörper 23 aus Fig. 12, und zwar einmal mit Schnittlegung zwischen zwei zackenförmigen Vorsprüngen 35 (Fig. 18 mit Detail C in Fig. 17) und einmal mit Schnittlegung durch die Spitze eines der zackenförmigen Vorsprünge 35 (Fig. 20 mit Detail D in Fig. 19).the Figures 17 to 20 show vertical sections through the in Fig. 10 The arrangement shown with a support element 22 formed from the base body 23 Fig. 12 , once with an incision between two serrated projections 35 ( Fig. 18 with detail C in Fig. 17 ) and once with a cut through the tip of one of the serrated projections 35 ( Fig. 20 with detail D in Fig. 19 ).

Wie insbesondere aus den Figuren 17 und 19 hervorgeht, durchstossen die zackenförmigen Vorsprünge 35 die Dichtung 21 linienförmig und liegen dadurch im unteren Angrenzungsbereich des Tragelements 22 direkt an dem unterhalb der Befestigungsbohrungen 10 hervorstehenden Randbereich 12b des Befestigungsprofilabschnitts 9 der Befestigungsprofilschiene 1 an (siehe Fig. 19), während der Grundkörper 23 in den Bereichen zwischen den zackenförmigen Vorsprüngen 35 unter elastischer Deformation der Dichtung 21 an dieser anliegt (siehe Fig. 17) .As in particular from the Figures 17 and 19th is shown, the serrated projections 35 pierce the seal 21 linearly and are thereby in the lower adjoining area of the support element 22 directly on the protruding below the fastening bores 10 edge region 12b of the fastening profile section 9 of the mounting profile rail 1 (see Fig. 19 ), while the base body 23 rests against the seal 21 in the areas between the serrated projections 35 with elastic deformation of the seal 21 (see FIG Fig. 17 ).

Die Figuren 21 bis 24 zeigen Vertikalschnitte durch die in Fig. 10 gezeigte Anordnung mit einem weiteren zweiteiligen Tragelement 22, welches einen Grundkörper 23 wie in Fig. 11 gezeigt aufweist, der hier aber ohne den Blechstreifen 30 verwendet wird. Der Grundkörper 23 ist auf seiner der Befestigungsprofilschiene 1 zugewandten Seite eben.the Figures 21 to 24 show vertical sections through the in Fig. 10 The arrangement shown with a further two-part support element 22, which has a base body 23 as in FIG Fig. 11 has shown, which is used here without the sheet metal strip 30. The base body 23 is flat on its side facing the fastening profile rail 1.

Bei der hier gezeigten Ausführungsform kommt eine Dichtung 21 zum Einsatz, welche in den Bereichen ihres Dichtungsprofils, die auf den hervorstehenden Randbereichen 12a, 12b des Befestigungsprofilabschnitts 9 der Befestigungsprofilschiene 1 angeordnet sind, in regelmässigen Abständen Stahlkugeln 36 identischer Grösse in zwei parallelen beabstandeten Reihen aufweist.In the embodiment shown here, a seal 21 is used which has steel balls 36 of identical size in two parallel spaced rows in the areas of its sealing profile that are arranged on the protruding edge areas 12a, 12b of the fastening profile section 9 of the fastening profile rail 1.

Die Schnittlegung verläuft bei den Figuren 21 bis 24 einmal zwischen den Stahlkugeln 36 (Fig. 22 mit Detail E in Fig. 21) und einmal durch je eine der Stahlkugeln 36 jeder Reihe (Fig. 24 mit Detail F in Fig. 23).The cut runs at the Figures 21 to 24 once between the steel balls 36 ( Fig. 22 with detail E in Fig. 21 ) and once through one of the steel balls 36 in each row ( Fig. 24 with detail F in Fig. 23 ).

Wie insbesondere aus den Figuren 21 und 23 hervorgeht, durchstossen die Stahlkugeln 36 die Dichtung 21 von innen her und bilden dadurch im oberen und unteren Angrenzungsbereich des Tragelements 22 mehrere nichtelastische Stützkörper, über die sich der Grundkörper 23 des Tragelements 22 an den ober- und unterhalb der Befestigungsbohrungen 10 hervorstehenden Randbereichen 12a, 12b des Befestigungsprofilabschnitts 9 der Befestigungsprofilschiene 1 abstützt (siehe Fig. 23). In den Bereichen zwischen den Kugeln 36 liegt er unter elastischer Deformation der Dichtung 21 an dieser an (siehe Fig. 21).As in particular from the Figures 21 and 23 As can be seen, the steel balls 36 pierce the seal 21 from the inside and thereby form several non-elastic support bodies in the upper and lower adjoining area of the support element 22, over which the base body 23 of the support element 22 extends at the above and below the fastening bores 10 protruding edge regions 12a, 12b of the fastening profile section 9 of the fastening profile rail 1 (see Fig. 23 ). In the areas between the balls 36, it rests against the seal 21 with elastic deformation (see FIG Fig. 21 ).

Während in der vorliegenden Anmeldung bevorzugte Ausführungen der Erfindung beschrieben sind, ist klar darauf hinzuweisen, dass die Erfindung nicht auf diese beschränkt ist und auch in anderer Weise innerhalb des Umfangs der nun folgenden Ansprüche ausgeführt werden kann.While preferred embodiments of the invention are described in the present application, it should be clearly pointed out that the invention is not restricted to these and can also be carried out in other ways within the scope of the claims which follow.
