DE 20 2008 004 373 U1 beschreibt ein im Querschnitt L-förmig ausgebildetes Isolatorprofil, das mit seinem quer zur Ebene des Fassadenelementes verlaufenden Schenkel an der Vorderseite eines Metallrahmens befestigt ist und mit seinem abstehenden Schenkel das Fassadenelement auf dessen Vorderseite übergreift. DE 20 2008 004 373 U1 describes a cross-sectionally L-shaped insulator profile, which is fastened with its transverse to the plane of the facade element legs on the front of a metal frame and engages with its protruding leg, the facade element on the front.

Eine der Aufgaben der vorliegenden Erfindung ist, den Wärmeübergang zwischen Rückseite der Fassadenelemente und Frontseite der Gebäudefassade zu verringern.

Another aspect is to provide the simplest possible structure of the fastening device with low production costs without sacrificing stability.

Erfindungsgemäß wird in oder an dem das Fassadenelement umgebenden Rahmen ein die Wärmeleitung reduzierendes Element (im Folgenden Thermosteg) zwischen Vorderseite und Rückseite des Fassadenelements vorgesehen.

Die vier Rahmenelemente stoßen an den Ecken vorzugsweise stumpf aneinander, sodass die in Fig. 1 links wiedergegebenen Verbindungsschrauben 2.7 in die Schraubnut 2.7a des benachbarten Rahmenelementes senkrecht zur Zeichenebene in Fig. 1 eingreifen. Hierdurch ergibt sich eine exakte Positionierung der vier Rahmenelemente relativ zueinander.The four frame elements preferably butt against one another at the corners, so that the in Fig. 1 Links reproduced connecting screws 2.7 in the screw groove 2.7a of the adjacent frame element perpendicular to the plane in Fig. 1 intervention. This results in an exact positioning of the four frame elements relative to each other.

Auf der Vorderseite des Metallrahmens 2 ist ein wenigstens teilweise aus einem Kunststoffmaterial bestehendes, die Wärmeübertragung reduzierendes Element 5 (Thermosteg) befestigt, das bei dem dargestellten Ausführungsbeispiel als aus Kunststoff bestehendes L-Profil mit drei Hohlkammern in dem längeren, sich in Querrichtung zur Glasplatte 1 erstreckenden Schenkel 5.1 ausgebildet ist, wobei die äußere Hohlkammer mit 5.4 bezeichnet ist. Mit dem abstehenden Schenkel 5.2 liegt dieser Thermosteg 5 über ein Dichtungselement 6 an der Außenseite der Glasplatte 1 an. Ein Dichtungselement 6a ist auf der Rückseite der Glasplatte 1 in einer Nut des z. B. aus Alumaterial bestehenden Metallrahmens 2 eingesetzt.On the front side of the metal frame 2, an at least partially made of a plastic material, the heat transfer reducing element 5 (Thermosteg) is fixed, which in the illustrated embodiment as an existing plastic L-profile with three hollow chambers in the longer, in the transverse direction to the glass plate. 1 extending leg is formed 5.1, wherein the outer hollow chamber is designated by 5.4. With the protruding leg 5.2 of this Thermosteg 5 is a sealing element 6 on the outside of the glass plate 1 at. A sealing element 6a is on the back of the glass plate 1 in a groove of z. B. aluminum material consisting of metal frame 2 used.

Der Thermosteg 5, durch den die Glasplatte 1 am Metallrahmen 2 eingespannt wird, ist aus einem stabilen Kunststoffmaterial ausgebildet, insbesondere aus Polyamid, wobei der den Druck der Einspannung der Glasplatte 1 aufnehmende Schenkel 5.2 des Thermostegs eine Dickenabmessung und/oder eine geometrische Form aufweist, die eine auf Dauer stabile Einspannung des Fassadenelementes gewährleistet.The Thermosteg 5, through which the glass plate 1 is clamped to the metal frame 2, is formed of a stable plastic material, in particular of polyamide, wherein the pressure of the clamping of the glass plate 1 receiving leg 5.2 of the thermal yoke has a thickness dimension and / or a geometric shape, which ensures a permanent stable clamping of the facade element.

Fig. 6 zeigt eine Querschnittsform eines Thermostegs 5, bei der an der Basis des Schenkels 5.2 bzw. an der Übergangsstelle zwischen den beiden Schenkeln 5.1 und 5.2 eine Abschrägung 5.3 angeformt ist, sodass die Basis des Schenkels 5.2 verbreitert ist. Bei diesem Ausführungsbeispiel ist die in Fig. 1 wiedergegebene äußere Hohlkammer 5.4 so ausgebildet, dass sie sich in die verbreiterte Basis des Schenkels 5.2 hinein erstreckt, wie dies Fig. 6 bei 5.4' zeigt. Fig. 6 shows a cross-sectional shape of a Thermostegs 5, in which at the base of the leg 5.2 and at the transition point between the two legs 5.1 and 5.2, a chamfer 5.3 is formed, so that the base of the leg is 5.2 widened. In this embodiment, the in Fig. 1 reproduced outer hollow chamber 5.4 formed so that it extends into the widened base of the leg 5.2, as this Fig. 6 at 5.4 'shows.

Am Schenkel 5.2 ist auf der Außenseite eine Vertiefung 5.6 angeformt, in die der Schraubenkopf der Schraube 7 eingreift, wie dies auch Fig. 1 zeigt.On the leg 5.2 a recess 5.6 is formed on the outside, in which engages the screw head of the screw 7, as well Fig. 1 shows.

Bei beiden Ausführungsformen des Thermostegs 5 sind am freien Ende des Schenkels 5.1 zwei abstehende beabstandete Schenkel 5.5 angeformt, die auf den Innenseiten mit Absätzen für einen Rasteingriff mit einem leistenförmigen Ansatz 2.1 am Metallrahmen 2 versehen sind. Durch diesen Rasteingriff kann der Thermosteg 5 am Metallrahmen 2 befestigt werden, bevor die nachfolgend erläuterten Befestigungsschrauben eingebracht werden.In both embodiments of the Thermostegs 5 5.1 two protruding spaced legs are formed at the free end of the leg 5.1, which are provided on the insides with heels for a latching engagement with a strip-shaped projection 2.1 on the metal frame 2. By this latching engagement, the thermo-yoke 5 can be fastened to the metal frame 2 before the fastening screws explained below are introduced.

Vorzugsweise ist das auf der Innenseite liegende Dichtungselement 6a zwischen Fassadenelement 1 und Metallrahmen 2 so ausgebildet, dass es auch zur Verringerung der Wärmeübertragung zwischen Fassadenelement 1 und Metallrahmen 2 dient. Bei dem dargestellten Ausführungsbeispiel ist dieses Dichtungselement 6a als Hohlkammerprofil elastisch ausgebildet und dicker als das außen liegende, steif ausgebildete Dichtungselement 6.Preferably, the sealing element 6a lying on the inside between the facade element 1 and metal frame 2 is designed such that it also reduces the heat transfer between facade element 1 and metal frame 2 is used. In the illustrated embodiment, this sealing element 6a is designed as a hollow chamber profile elastic and thicker than the outer, rigidly formed sealing element. 6

An der innen liegenden Dichtung 6a ist auf dem Außenumfang eine Dichtlippe 6a1 angeformt, welche über den Umfang des Fassadenelementes 1 vorsteht und den Abstand zwischen Umfang des Fassadenelementes 1 und Thermosteg 5 auf der Innenseite abdichtet, indem diese Lippe 6a1 an dem Schenkel 5.1 des Thermostegs 5 anliegt.On the inner seal 6a, a sealing lip 6a1 is integrally formed on the outer circumference, which projects beyond the circumference of the facade element 1 and seals the distance between the periphery of the facade element 1 and Thermosteg 5 on the inside by this lip 6a1 on the leg 5.1 of the Thermostegs. 5 is applied.

Vorzugsweise ist in dem Spalt zwischen Außenumfang des Fassadenelementes 1 und Thermosteg 5 nahe der Außenseite des Fassadenelementes ein weiteres Dichtungselement 60 vorgesehen, das den Spalt zwischen Fassadenelement 1 und Thermosteg 5 nach außen abdichtet. Diese Dichtung 60 besteht vorzugsweise aus einem Schaumstoffmaterial, insbesondere aus einem geschlossenzelligen PU-Schaum. Dieses Dichtungselement 60 dient nicht nur zur zusätzlichen Abdichtung des Spaltes zwischen Fassadenelement 1 und Thermosteg 5, sondern auch zur Begrenzung des Luftraumes zwischen Fassadenelement 1 und Thermosteg 5, in dem durch Konvektion der Luft die Wärmeübertragung begünstigt werden könnte. Durch die kleineren Hohlräume wird die Konvektion unterdrückt. Wie Fig. 2 zeigt, wird durch die Dichtungen 60 und 6a1 der Hohlraum zwischen Fassadenelement 1 und Thermosteg 5 bzw. Metallrahmen 2 in drei Hohlkammern zwischen den Dichtungen 6 und 6a unterteilt.Preferably, in the gap between the outer periphery of the facade element 1 and Thermosteg 5 near the outside of the facade element, a further sealing element 60 is provided which seals the gap between the facade element 1 and 5 Thermosteg to the outside. This seal 60 is preferably made of a foam material, in particular of a closed-cell PU foam. This sealing element 60 serves not only for additional sealing of the gap between the facade element 1 and Thermosteg 5, but also to limit the air space between the facade element 1 and Thermosteg 5, in which by convection of the air heat transfer could be favored. Due to the smaller cavities convection is suppressed. As Fig. 2 shows, is divided by the seals 60 and 6a1 of the cavity between the facade element 1 and 5 Thermosteg or metal frame 2 in three hollow chambers between the seals 6 and 6a.

Wie Fig. 1 bis 3 zeigen, sind bei dem Aufbau im Wesentlichen zwei Hohlräume jeweils durch Dichtungen begrenzt, zum einen der Hohlraum zwischen Außenumfang des Fassadenelementes 1 und Thermosteg 5 und zum anderen der Hohlraum zwischen den gegenüberliegenden Thermostegen 5 und 5' benachbarter Fassadenelemente, wobei letzterer Hohlraum vorzugsweise mit Schaumstoffmaterial im Wesentlichen ausgefüllt wird, um Luftkonvektion zu vermeiden, während ersterer Hohlraum zur Ableitung von eindringender Feuchtigkeit frei gehalten wird und nur in seinem Querschnitt durch die Dichtungen 60 und 6a1 begrenzt wird.As Fig. 1 to 3 show, in the structure essentially two cavities are each limited by seals, on the one hand, the cavity between the outer periphery of the facade element 1 and Thermosteg 5 and on the other, the cavity between the opposite Thermostegen 5 and 5 'adjacent facade elements, the latter cavity preferably with foam material in the Is substantially filled to avoid air convection, while the first cavity is kept free for the discharge of moisture penetrating and limited only in its cross section through the seals 60 and 6a1.

Mit T ist nur zur Erläuterung eine gedachte Trennlinie des Aufbaus zwischen den Rahmen 2 und 2' der beiden nebeneinander angeordneten Fassadenelemente 1 und 1' bezeichnet, wobei zwei Ausführungsbeispiele auf den beiden Seiten der Trennlinie wiedergegeben sind. An dem in Fig. 1 linken Thermosteg 5' ist zu dessen Befestigung an dem Metallrahmen 2 als Beispiel eine Schraube 7 vorgesehen, die sich von der Vorderseite des Thermostegs 5' durch den langen Schenkel 5.1 bis in den Metallrahmen 2 erstreckt, der in einem vorstehenden, als Leiste ausgebildeten Ansatz 2.1, der längs des Rahmens verläuft, eine Gewindebohrung zur Aufnahme der Schraube 7 aufweist. Anstelle einer Gewindebohrung kann auch ein senkrecht zur Zeichnungsebene durchgehender Kanal im Metallrahmen 2 bzw. in dem Ansatz 2.1 vorgesehen werden, in den Schrauben 7 bzw. 70 mit einem selbstschneidenden Gewinde eingeschraubt werden.T is an illustrative dividing line of the construction between the frame 2 and 2 'of the two juxtaposed facade elements 1 and 1' for explanation only, with two embodiments are shown on the two sides of the dividing line. At the in Fig. 1 left Thermosteg 5 'is provided for its attachment to the metal frame 2 as an example a screw 7 extending from the front of the Thermostegs 5' by the long Leg 5.1 extends into the metal frame 2, which has a threaded bore for receiving the screw 7 in a protruding, trained as a bar approach 2.1, which runs along the frame. Instead of a threaded hole, a channel perpendicular to the plane of the drawing in the metal frame 2 or in the approach 2.1 can be provided, are screwed into the screws 7 and 70 with a self-tapping thread.

Vorzugsweise wird in dem Ansatz 2.1 eine Nut mit einer Riffelung auf den gegenüberliegenden Innenseiten vorgesehen, in die die Schrauben 7 bzw. 70 eingreifen, wie Fig. 2 zeigt.Preferably, in the approach 2.1 a groove is provided with a corrugation on the opposite inner sides, in which the screws 7 and 70 engage, such as Fig. 2 shows.

Durch über den Umfang der Glasplatten 1 verteilt angeordnete Schrauben 7 wird die Glasplatte 1 bzw. 1' mittels des Thermostegs 5 am Metallrahmen 2 zwischen den Dichtungen 6 und 6a eingespannt.By distributed over the circumference of the glass plates 1 arranged screws 7, the glass plate 1 or 1 'is clamped by means of the thermal yoke 5 on the metal frame 2 between the seals 6 and 6a.

Um die Wärmeübertragung zwischen Vorderseite und hinter der Glasplatte liegendem Metallrahmen 2 weiter zu verringern, ist an dem in Fig. 1 rechten Thermosteg 5 als Beispiel eine verkürzte Befestigungsschraube 70 vorgesehen, die in den Ansatz 2.1 des Metallrahmens 2 eingreift und mit ihrem Schraubenkopf in der inneren Hohlkammer des Schenkels 5.1 des Thermostegs 5 endet, die in einem beträchtlichen Abstand von der in Fig. 1 unten liegenden Vorderseite des Thermostegs 5 angeordnet ist. Zum Anbringen der verkürzten Befestigungsschraube 70 kann am Thermosteg 5 eine Bohrung von der Vorderseite aus in den Schenkel 5.1 bzw. durch die die äußere Hohlkammer 5.4 und die mittlere Hohlkammer begrenzenden Stege eingebracht werden, durch die die Befestigungsschraube 70 eingesetzt und in den Metallrahmen 2 eingeschraubt werden kann. Dadurch, dass die verkürzte Befestigungsschraube 70 sich nicht bis zur Vorderseite des Thermostegs 5 erstreckt, kann die Wärmeübertragung zwischen Vorderseite des Fassadenelementes und dahinter angeordnetem Metallrahmen 2 deutlich verringert werden.In order to reduce the heat transfer between the front and lying behind the glass plate metal frame 2 on, is on the in Fig. 1 right Thermosteg 5 as an example a shortened fastening screw 70 is provided, which engages in the neck 2.1 of the metal frame 2 and ends with its screw head in the inner hollow chamber of the leg 5.1 of the Thermostegs 5, which at a considerable distance from the in Fig. 1 located below the front of the Thermostegs 5 is arranged. For attaching the shortened fastening screw 70, a bore can be introduced from the front into the limb 5. 1 or through the limbs delimiting the outer hollow chamber 5. 4 and the middle hollow chamber, through which the fastening screw 70 is inserted and screwed into the metal frame 2 can. Due to the fact that the shortened fastening screw 70 does not extend to the front of the thermal web 5, the heat transfer between the front side of the facade element and the metal frame 2 arranged behind it can be significantly reduced.

Zur Stabilisierung der Verbindung zwischen Thermosteg 5 und Metallrahmen 2 kann als Beispiel an dem rechten Thermosteg 5 in Fig. 1 ein Metallelement 8 zwischen Schraubenkopf und Thermosteg eingesetzt werden, durch das die Stabilität der Befestigung des Thermostegs 5 an dem Metallrahmen 2 dadurch verbessert wird, dass sowohl der Schraubenkopf als auch der Schraubenschaft jeweils an einem Metallteil angreifen. Das Metallelement 8 kann in Form einer Beilagscheibe oder eines Metallstreifens mit Bohrungen in die Hohlkammer im Schenkel 5.1 des Thermostegs eingesetzt werden.To stabilize the connection between Thermosteg 5 and metal frame 2 can be as an example on the right Thermosteg 5 in Fig. 1 a metal element 8 between the screw head and Thermosteg be used, by which the stability of the attachment of the Thermostegs 5 is improved on the metal frame 2 in that both the screw head and the screw shaft each engage a metal part. The metal element 8 may be in shape a washer or a metal strip with holes in the hollow chamber in the leg 5.1 of the thermo track are used.

Auf der linken Hälfte der Fig. 1 ist ein plattenförmiges Metallelement 8a auf der Außenseite des Thermostegs 5 wiedergegeben, durch das die längere Schraube 7 verläuft, wobei der Schraubenkopf an dem Metallelement 8a anliegt. Ein solches Metallelement 8a, das sich im Wesentlichen über die Breite des Schenkels 5.2 des Thermostegs erstreckt, wird vorzugsweise auch als Eckverbindungselement verwendet, wie dies nachfolgend anhand der Fig. 5 näher erläutert wird.On the left half of the Fig. 1 a plate-shaped metal element 8a is reproduced on the outside of the thermo yoke 5, through which the longer screw 7 extends, the screw head resting against the metal element 8a. Such a metal element 8a, which extends substantially over the width of the leg 5.2 of the thermal yoke, is preferably also used as a corner connecting element, as described below with reference to FIGS Fig. 5 is explained in more detail.

An einem Fassadenelement können über den Umfang verteilt auch längere Schrauben 7 und verkürzte Schrauben 70 vorgesehen werden.On a facade element distributed over the circumference also longer screws 7 and shortened screws 70 can be provided.

Unabhängig davon, ob auf der Vorderseite des Thermostegs 5 eine Bohrung für eine verkürzte Befestigungsschraube 70 oder eine durchgehende Befestigungsschraube 7 vorgesehen wird, wird die Vorderseite des Thermostegs 5 vorzugsweise durch eine Abdeckleiste 9, abgedeckt, durch die die Einfassung der Glasplatte 1 auf der Frontseite ein sehr schlankes Aussehen erhält. Diese im Querschnitt U-förmige Leiste 9 kann mit den beiden abgewinkelten Schenkeln am Thermosteg 5 durch Rastwirkung eingeclipst werden. Zur Befestigung sind in Fig. 1 seitlich eingesetzte Schrauben oder Hohlstifte 9.1 vorgesehen. Dieses Abdeckprofil 9 für die Vorderseite des Thermostegs 5 kann aus Metall oder ebenfalls aus einem Kunststoff bestehen. Vorzugsweise wird diese Abdeckleiste 9 aus Aluminium gefertigt, sie kann aber auch aus Edelstahl oder Messing bestehen.Regardless of whether on the front of the Thermostegs 5 a hole for a shortened fastening screw 70 or a continuous fastening screw 7 is provided, the front of the Thermostegs 5 is preferably covered by a cover 9, through which the enclosure of the glass plate 1 on the front looks very slim. This in cross-section U-shaped bar 9 can be clipped with the two angled legs on the thermostatic 5 by locking action. For attachment are in Fig. 1 laterally inserted screws or hollow pins 9.1 provided. This cover profile 9 for the front of the thermo-yoke 5 may be made of metal or also of a plastic. Preferably, this cover strip 9 is made of aluminum, but it can also be made of stainless steel or brass.

In einem Abstand von der Vorderseite sind seitlich an den Thermostegen 5 Dichtlippen 10 vorgesehen, die in eine entsprechende Nut im Thermosteg 5 eingesetzt sind und durch Anlage an der gegenüberliegenden Dichtlippe 10' am gegenüberliegenden Thermosteg den Spalt zwischen den beiden Thermostegen 5 und 5' abdecken. Wie Fig. 2 zeigt, kann anstelle einer Nut im Thermosteg 5 auch ein im Querschnitt T-förmiger Ansatz am Thermosteg vorgesehen sein, an dem die Dichtlippe 10 befestigt wird.At a distance from the front 5 sealing lips 10 are provided laterally to the Thermostegen, which are inserted into a corresponding groove in the Thermosteg 5 and by conditioning against the opposite sealing lip 10 'at the opposite Thermosteg the gap between the two Thermostegen 5 and 5' cover. As Fig. 2 shows, instead of a groove in the Thermosteg 5 also a cross-sectionally T-shaped projection may be provided on the Thermosteg on which the sealing lip 10 is attached.

Die Hohlkammern des Thermostegs 5 können vorzugsweise eine Schaumstofffüllung aufweisen, um die Wärmeübertragung zu reduzieren, nachdem eine Schaumstofffüllung in den Hohlräumen die Wärmeübertragung besser reduziert als Luft in diesen Hohlräumen.The hollow chambers of the thermo-guide 5 may preferably have a foam filling to reduce the heat transfer, after a foam filling in the cavities better reduces the heat transfer than air in these cavities.

Vorzugsweise wird auch in dem Hohlraum zwischen den gegenüberliegenden Außenseiten der Thermostege 5 und 5' innerhalb der Dichtlippen 10 und 10' eine Schaumstofffüllung eingebracht, beispielsweise durch Einschieben von Schaumstoffstreifen nach Montage der Thermostege, um die Wärmeisolierung zwischen Außenseite und Metallrahmen 2 zu verbessern.Preferably, in the cavity between the opposite outer sides of the thermo sets 5 and 5 'within the sealing lips 10 and 10' introduced a foam filling, for example by inserting foam strips after mounting the Thermostege to improve the heat insulation between the outside and metal frame 2.

In dem im Querschnitt etwa rechteckigen Metallrahmen 2 sind nahe der Rück- bzw. Innenseite des Thermostegs 5 nebeneinander liegende Kammern 2.2 und 2.3 ausgebildet, die zum Außenumfang des Metallrahmens 2 hin offen sind, wobei in der äußeren Kammer 2.2 das Dichtelement 11 eingesetzt ist, das sich in die Kammer 2.2' des gegenüberliegenden Metallrahmens 2' erstreckt und zum Abdichten des Spalts zwischen den nebeneinander liegenden Rahmen 2 und 2' dient. Dieses Dichtungselement 11 ist einstückig und nicht durch die Trennlinie T getrennt. Die entsprechende, sich zwischen den beiden Metallrahmen 2 und 2' erstreckende Dichtung 12 ist am innen liegenden Ende des Metallrahmens 2 in eine seitlich offene Kammer oder Nut der Metallrahmen 2 und 2' eingesetzt.In the cross-sectionally approximately rectangular metal frame 2, adjacent chambers 2.2 and 2.3 are formed close to the rear or inside of the thermo-guide 5, which are open to the outer periphery of the metal frame 2, wherein in the outer chamber 2.2, the sealing element 11 is inserted extends into the chamber 2.2 'of the opposite metal frame 2' and serves to seal the gap between the adjacent frames 2 and 2 '. This sealing element 11 is integral and not separated by the dividing line T. The corresponding, between the two metal frame 2 and 2 'extending seal 12 is inserted at the inner end of the metal frame 2 in a laterally open chamber or groove of the metal frame 2 and 2'.

Durch Verschrauben des Thermostegs 5 mit dem Metallrahmen 2 und die Dichtungen 10, 11 und 12 zwischen benachbarten Metallrahmen wird der Aufbau wind- und regendicht.By screwing the Thermostegs 5 with the metal frame 2 and the seals 10, 11 and 12 between adjacent metal frame, the structure is wind and rainproof.

Der Metallrahmen 2 hat im Mittelbereich seiner etwa rechteckigen Längserstreckung des Querschnitts vorzugsweise einen etwa U-förmigen Abschnitt, dessen offene Seite auf dem Außenumfang des Rahmens 2 liegt. Auf einem Mittelabschnitt des sich quer zur Ebene der Glasplatte 1 erstreckenden Metallrahmens 2 ist eine längliche Hohlkammer 2.4 ausgebildet, in die die Befestigungsanker 3 eingesetzt sind. Mit 2.5 ist ein Absatz in der Hohlkammer 2.4 bezeichnet, an dem das verbreiterte Ende 3.8 des Befestigungsankers 3 zum Anliegen kommen kann. Bei 2.6 ist eine Nut in der Hohlkammer 2.4 ausgebildet, in die ein abgewinkelter Ansatz 3.1 des Befestigungsankers 3 eingreift, sodass der Befestigungsanker 3 in Längs- und Querrichtung in Fig. 1 in dem Metallrahmen 2 gehalten ist und die am Metallrahmen 2 auftretenden Kräfte aufnehmen kann. Mit 3.2 sind Nieten oder Schrauben bezeichnet, mittels denen der plattenförmige Befestigungsanker 3 mit dem Metallrahmen 2 fest verbunden ist. Die Nieten oder Schrauben 3.2 sind in dem seitlich offenen, U-förmigen Mittelbereich des Metallrahmens angeordnet.The metal frame 2 has in the middle region of its approximately rectangular longitudinal extent of the cross section preferably an approximately U-shaped portion whose open side lies on the outer circumference of the frame 2. On an intermediate portion of the metal frame 2, which extends transversely to the plane of the glass plate 1, an elongated hollow chamber 2.4 is formed into which the fastening anchors 3 are inserted. With 2.5 a paragraph in the hollow chamber 2.4 is referred to, where the widened end of the fastening anchor 3 3.8 can come to rest. In 2.6, a groove in the hollow chamber 2.4 is formed, in which engages an angled approach 3.1 of the fastening anchor 3, so that the fastening anchor 3 in the longitudinal and transverse direction in Fig. 1 is held in the metal frame 2 and can absorb the forces occurring on the metal frame 2. With 3.2 rivets or screws are designated by means of which the plate-shaped fastening anchor 3 is firmly connected to the metal frame 2. The rivets or screws 3.2 are arranged in the laterally open, U-shaped central region of the metal frame.

In der Ansicht der Fig. 1 erstreckt sich der plattenförmige Befestigungsanker 3, wie auch Fig. 3 zeigt, aus dem senkrecht liegenden Abschnitt des Metallrahmens 2 in Richtung auf das mit der Fassade verbundene Plattenelement 4, in dem ein im Querschnitt T-förmiger Eingriffsausschnitt 4.1 ausgebildet ist, in den der Befestigungsanker 3 mit einem Quersteg 3.3 eingreift. In Fig. 1 ist dieser im Querschnitt T-förmige Eingriffsausschnitt 4.1 auf der rechten Seite in Querrichtung zum Befestigungsanker 3 größer ausgebildet als der Ausschnitt 4.1' auf der linken Seite, sodass durch die auf der rechten Seite vorhandenen Toleranzen zwischen Platte 4 und Befestigungsanker 3 beispielsweise Wärmedehnungen und Montageungenauigkeiten aufgenommen werden können.In the view of Fig. 1 extends the plate-shaped attachment anchor 3, as well Fig. 3 shows, from the vertical portion of the metal frame 2 in the direction of the connected to the facade plate member 4, in which a cross-sectionally T-shaped engaging cutout 4.1 is formed, in which the fastening anchor 3 engages with a transverse web 3.3. In Fig. 1 this cross-sectional T-shaped engagement cutout 4.1 on the right side in the transverse direction to the fastening anchor 3 is larger than the cutout 4.1 'on the left side, so absorbed by the existing tolerances on the right side between plate 4 and anchor 3, for example, thermal expansion and assembly inaccuracies can be.

An dem Quersteg 3.3 der Befestigungsanker 3 ist eine Ringöse 3.4 angeformt, die mit einem Gewinde versehen ist und einen Gewindezapfen 3.5 aufnimmt, der, wie Fig. 3 zeigt, in einem Hohlraum über der Platte 4 eingesetzt ist und mit dem unteren Ende auf dieser aufliegt. Die Platte 4 ist die mit dem T-förmigen Eingriffsausschnitt 4.1 (Fig. 1 und 2) versehen. Durch diesen Gewindezapfen 3.5 kann die Höhenposition des Metallrahmens 2 relativ zu der an der Rohfassade befestigten Platte 4 eingestellt werden.At the cross bar 3.3 of the anchor 3, a ring eyelet 3.4 is formed, which is provided with a thread and a threaded pin 3.5 receives, which, as Fig. 3 shows, is inserted in a cavity above the plate 4 and rests with the lower end on this.

Fig. 3 zeigt an einem nach oben ragenden Schenkel 3.6 des Befestigungsankers 3 eine Bohrung 3.7, mittels der das in Fig. 3 untere Fassadenelement 1 an einem Kran oder dergleichen aufgehängt werden kann. Wenn nach dem Positionieren des unteren Fassadenelementes mit Rahmen 2 der Platte 4 das obere Fassadenelement 1' mit Rahmen 2' angesetzt wird, erstreckt sich dieser vorstehende Abschnitt 3.6 der Befestigungsanker 3 durch eine entsprechende Ausnehmung in dem darüber aufgesetzten Metallrahmen 2'. Der vorstehende Abschnitt 3.6 ist am Befestigungsanker 3 zwischen dem verbreiterten Ende 3.8 und dem abgewinkelten Ansatz 3.1 (Fig. 1) ausgebildet, wobei dieser Abschnitt 3.6 eine Verlängerung des plattenförmigen Abschnitts des Befestigungsankers 3 bildet. Fig. 3 shows on an upwardly projecting leg 3.6 of the fastening anchor 3 a hole 3.7, by means of which in Fig. 3 lower facade element 1 can be hung on a crane or the like. If, after positioning the lower facade element with frame 2 of the plate 4, the upper facade element 1 'with frame 2' is recognized, this projecting section 3.6 of the anchor 3 extends through a corresponding recess in the metal frame 2 'placed above it. The protruding section 3.6 is at the attachment anchor 3 between the widened end 3.8 and the angled approach 3.1 ( Fig. 1 ), wherein this section 3.6 forms an extension of the plate-shaped portion of the fastening anchor 3.

Wie Fig. 3 zeigt, ist der quer verlaufende Abschnitt des Metallrahmens 2 mit dem gleichen Querschnittsprofil ausgebildet wie der in Fig. 1 senkrecht verlaufende Rahmenabschnitt. In entsprechender Weise ist auch in Fig. 3 der quer verlaufende Thermosteg 5 mit der gleichen Querschnittsform ausgebildet wie der in Fig. 1 senkrecht verlaufende Thermosteg 5.As Fig. 3 shows, the transverse portion of the metal frame 2 is formed with the same cross-sectional profile as in Fig. 1 vertical frame section. In appropriate way is also in Fig. 3 the transverse Thermosteg 5 is formed with the same cross-sectional shape as in Fig. 1 vertical thermosteg 5.

An den Ecken des Metallrahmens 2 eines Fassadenelementes kann der senkrecht verlaufende Thermosteg 5 auf Gehrung geschnitten und mit dem dazu quer verlaufenden Abschnitt verbunden sein oder die quer zueinander liegenden Abschnitte der Thermostege können stumpf aneinander stoßen, wobei an den Ecken eine entsprechende Abdeckung vorgesehen werden kann.At the corners of the metal frame 2 of a facade element, the vertically extending Thermosteg 5 can be mitred and connected to the transverse section or the transverse sections of the thermo sets may butt together, with a corresponding cover can be provided at the corners.

Die in Fig. 1 am rechten Thermosteg 5 wiedergegebene Verbindungsschraube 14 kann, wie dargestellt, kürzer ausgebildet werden, wenn die Abschnitte der Thermostege 5 an den Ecken auf Gehrung geschnitten sind und nicht stumpf aneinander stoßen wie in Fig. 4. Fig. 4 shows schematically in a front view blunt abutting portions of the thermo set 5 in front of the underlying metal frame 2, wherein the two ends of the blunt abutting thermo sets are connected by a connecting screw 14. In the Fig. 1 As shown, the connection screw 14 shown on the right-hand thermosteg 5 can be made shorter if the sections of the thermo-set 5 are mitered at the corners and do not butt against each other as in FIG Fig. 4 ,

Die Verbindungsschraube 14 erstreckt sich quer durch den in Fig. 4 senkrecht verlaufenden Abschnitt des Thermostegs 5 und greift an dem in Fig. 4 waagrecht liegenden Abschnitt des Thermostegs 5 in die in Fig. 2 mit 5.7 bezeichnete Schraubnut des Thermostegs 5 ein, die längs der innen liegenden Hohlkammer in Fig. 2 verläuft. Hierbei greift die Verbindungsschraube 14 senkrecht zur Zeichnungsebene in Fig. 2 in diese Schraubnut 5.7 ein. In den Fig. 6 und 7 ist diese Schraubnut 5.7 seitlich von der Mitte der zugeordneten Hohlkammer angrenzend an die Seitenwand des Thermostegs 5 angeordnet.The connecting screw 14 extends transversely through the in Fig. 4 vertically extending portion of the Thermostegs 5 and engages the in Fig. 4 horizontal section of Thermosteg 5 in the in Fig. 2 with 5.7 designated Schraubnut the Thermostegs 5 a, along the inner hollow chamber in Fig. 2 runs.
