Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung von plattenförmigen Fassadenelementen einer vorzugsweise hinterlüfteten Fassadenverkleidung, an einer mit einem Wärmedämmputz und ggf. mit Fenstern ausgestatteten Gebäudewand mittels Befestigungselementen, die jeweils durch ein Außenteil und ein Innenteil gebildet sind, von denen das Außen- oder Innenteil mit einer Aufstandsfläche für das jeweils obere Fassadenelement und das Außenteil jeweils mit einer Anlagefläche für das obere und das untere Fassadenelement versehen ist und die gemeinsam auf einem Schraubenbolzen angeordnet sind, der von einem an der Gebäudewand zu befestigenden Tragelement gehalten wird und unter Anpressung von Außenteil und Innenteil eine formschlüssige Verbindung zwischen Befestigungselement und Tragelement herstellt.The invention relates to a device for fastening plate-shaped facade elements of a preferably rear-ventilated facade cladding, on a building wall equipped with a thermal insulation plaster and possibly with windows by means of fastening elements, each of which is formed by an outer part and an inner part, of which the outer or inner part with a Footprint for the respective upper facade element and the outer part is provided with a contact surface for the upper and lower facade element and which are arranged together on a screw bolt, which is held by a support element to be fastened to the building wall and one is pressed against the outer part and inner part produces a positive connection between the fastening element and the supporting element.

Befestigungsvorrichtungen der voranstehend beschriebenen Art sind aus der EP-A2-0 415 201 bekannt. Diese besitzen den Vorteil, daß mit einem Minimum an Teilen innerhalb kürzestmöglicher Zeit und mit geringem Aufwand Fassadenverkleidungen aus vorgefertigten plattenförmigen Fassadenelementen, wie Gläsern, Metallen, Natursteinen und sonstigen geeigneten Werkstoffen errichtet werden können, wobei die Befestigungsvorrichtungen auf einfache Weise einen Ausgleich sowohl der bauseitigen Maßabweichungen als auch der Fertigungstoleranzen der Fassadenelemente ermöglichen. Die Last der Fassadenelemente wird hierbei durch Formschluß auf die Gebäudewand, und zwar vorzugsweise in das jeweils nächste Stockwerk übertragen, so daß die Schraubenbolzen der Befestigungselemente lediglich die Wind-ggf. Gerüstlasten aufzunehmen und für den konstruktiven Formschluß zu sorgen haben.Fastening devices of the type described above are known from EP-A2-0 415 201. These have the advantage that facade cladding made of prefabricated plate-shaped facade elements such as glasses, metals, natural stones and other suitable materials can be erected with a minimum of parts within the shortest possible time and with little effort, the fastening devices being able to easily compensate for both the on-site dimensional deviations as well as the manufacturing tolerances of the facade elements. The load of the facade elements is transferred to the wall of the building by positive locking, preferably to the next floor, so that the bolts of the fasteners only the wind if necessary. Take up scaffolding loads and have to ensure the constructive form fit.

Bei der aus der EP-A2-0 415 201 bekannten Konstruktion werden die Befestigungselemente an einem Spalier aus parallel zueinander vor der Gebäudewand angeordneten Tragprofilen befestigt. Hierbei handelt es sich um rohrförmige Profile mit einer mindestens Geschoßhöhe entsprechenden Länge.In the construction known from EP-A2-0 415 201, the fastening elements are fastened to a trellis made of support profiles arranged parallel to one another in front of the building wall. These are tubular profiles with a length corresponding to at least the floor height.

Diese bis zu 6 m langen Konstruktionsteile der Spalierkonstruktionen haben den Nachteil, daß Temperaturänderungen zu thermischen Längenänderungen der Unterkonstruktion führen, die durch Fugen zwischen den Fassadenteilen aufgenommen werden müssen. Außerdem bereitet es wegen der thermisch bedingten Relativbewegungen Schwierigkeiten, die Fassadenelemente gegenüber separat an der Gebäudewand befestigten Fenstern zuverlässig abzudichten.These up to 6 m long construction parts of the trellis constructions have the disadvantage that temperature changes lead to thermal changes in the length of the substructure, which have to be absorbed by joints between the facade parts. In addition, because of the thermally induced relative movements, it is difficult to reliably seal the facade elements from windows that are separately fastened to the building wall.

Weiterhin ist aus dem DE-U-92 08 252 eine Vorrichtung zur Halterung plattenförmiger Fassadenelemente bekannt, bei der die die Fassadenelemente aufnehmenden Halteelemente an vertikal entlang der Gebäudewand verlaufenden Tragprofilen befestigt sind. Zur Aufnahme der Halteelemente weisen die Tragprofile dieser bekannten Konstruktion in Längsrichtung verlaufende Befestigungsnuten auf. Zwar können aufgrund der längs verlaufenden Befestigungsnuten der Tragprofile die Befestigungselemente auf einfache Weise befestigt und in die entsprechende Lage verschoben werden, jedoch treten auch bei dieser Konstruktion thermische Längenänderungen der Unterkonstruktion auf, da die von den Tragprofilen gebildete Spalierkonstruktion aus langen, mindestens einer Geschoßhöhe entsprechenden Tragprofilen gebildet ist.Furthermore, from DE-U-92 08 252 a device for holding plate-shaped facade elements is known, in which the holding elements receiving the facade elements are fastened to support profiles running vertically along the building wall. To accommodate the holding elements, the support profiles of this known construction have longitudinal fastening grooves. Although the fastening elements can be fastened and moved into the appropriate position in a simple manner due to the longitudinal fastening grooves of the support profiles, thermal changes in the length of the substructure also occur in this construction, since the trellis structure formed by the support profiles consists of long support profiles corresponding to at least one storey height is formed.

Der Erfindung liegt die Aufgabe zugrunde, die voranstehend geschilderten Nachteile der bekannten Konstruktionen zu vermeiden und diese derart weiterzubilden, daß das Auftreten von Relativbewegungen aufgrund thermischer Längenveränderungen vermieden wird.The invention is based on the object of avoiding the disadvantages of the known constructions described above and developing them in such a way that the occurrence of relative movements due to thermal changes in length is avoided.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß der Schraubenbolzen jedes Befestigungselementes in ein Ankerschienenstück eingesetzt und mittels seines Kopfes längsverschiebbar am Ankerschienenstück gehalten ist, das mittels zweier Schrauben auf einer mit der Gebäudewand verbundenen Konsole oder Zarge bzw. einem Blendrahmen eines Fensters befestigt ist, wobei die Konsole oder Zarge unter der Putzschicht innerhalb der Wärmedämmung angeordnet ist.The solution to this problem by the invention is characterized in that the screw bolt of each fastener is inserted into an anchor rail piece and is held longitudinally displaceably by means of its head on the anchor rail piece, which is fastened by means of two screws to a bracket or frame connected to the building wall or to a window frame is, the console or frame is arranged under the plaster layer within the thermal insulation.

Durch diese erfindungsgemäße Weiterbildung wird der Vorteil erreicht, daß durch den Ersatz der bisherigen, aus bis zu 6 m langen Tragprofilen bestehenden Spalierkonstruktion durch eine Vielzahl kurzer, etwa 10 cm langer Ankerschienenstücke das Problem der Längenveränderung durch Temperaturänderungen bzw. ein entstehendes Temperaturgefälle beseitigt wird. Während die Tragprofile der Spalierkonstruktion atmosphärisch freilagen und sich gegenüber der eine etwa gleichmäßige Temperatur beibehaltenden Gebäudewand aufheizten, liegen die kurzen Ankerschienenstücke der erfindungsgemäßen Weiterbildung zwar ebenfalls atmosphärisch frei, führen jedoch zu keinen thermisch bedingten Relativbewegungen, da sie kurz sind und nur einen Befestigungspunkt aufnehmen. Außerdem liegen die die Ankerschienenstücke tragenden Konsolen und Befestigungswinkel innerhalb der auf die Gebäudewand aufgebrachten und von einer Putzschicht abgedeckten Dämmschicht, so daß diese frei von Dehnungsproblemen aufgrund von Temperaturdifferenzen sind.This further development according to the invention has the advantage that by replacing the existing trellis construction consisting of up to 6 m long supporting profiles with a large number of short, approximately 10 cm long anchor rail pieces, the problem of length changes due to temperature changes or an emerging temperature gradient is eliminated. While the supporting profiles of the trellis construction are exposed to the atmosphere and heated up compared to the building wall, which maintains an approximately uniform temperature, the short anchor rail pieces of the further development according to the invention are also exposed to the atmosphere, but do not lead to any thermally induced relative movements, since they are short and only accommodate one attachment point. In addition, the brackets and fastening brackets carrying the anchor rail pieces lie within the insulation layer applied to the building wall and covered by a plaster layer, so that these are free from expansion problems due to temperature differences.

Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Weiterbildung ist darin zu sehen, daß der Einbau von Fenstern und deren Abdichtung derart einfach geworden sind, daß sie ohne zusätzliche anschließende Versiegelungsmaßnahmen wetterdicht in die Fassade integriert sind. Hierbei bleibt die bei der bekannten Konstruktion bestehende Möglichkeit voll erhalten, einen Ausgleich sowohl der bauseitigen Maßabweichungen als auch der Fertigungstoleranzen der Fassadenelemente und Fensterteile vorzunehmen.Another significant advantage of the development according to the invention can be seen in the fact that the installation of windows and their sealing have become so simple that they are integrated in the facade in a weatherproof manner without additional subsequent sealing measures. In this case, the possibility existing with the known construction is fully retained to compensate for both the on-site dimensional deviations and the manufacturing tolerances of the facade elements and window parts.

Weiterhin erlaubt die Längsverschiebbarkeit der Schraubenbolzen mittels ihrer Köpfe entlang der Ankerschienenstücke eine einfache Montage und ein leichtes Erzielen der notwendigen Justierbarkeit der die Fassadenelemente haltenden Befestigungselemente.Furthermore, the longitudinal displaceability of the screw bolts by means of their heads along the anchor rail pieces allows simple assembly and easy achievement of the necessary adjustability of the fastening elements holding the facade elements.

Gemäß einem weiteren Merkmal der Erfindung wird die Konsole über Befestigungswinkel mit der Gebäudewand verbunden, wobei es vorteilhaft ist, zwischen den Befestigungswinkel und der Konsole eine thermische Trennung bewirkende Zwischenlagen anzuordnen. Damit ergibt sich eine thermisch von der Gebäudewand getrennte Befestigung der als Tragelement für die Befestigungselemente dienenden Ankerschienenstücke.According to a further feature of the invention, the bracket is connected to the building wall via fastening brackets, it being advantageous to arrange intermediate layers causing thermal separation between the fastening bracket and the bracket. This results in a fastening that is thermally separate from the building wall and serves as a supporting element for the fastening elements serving anchor rail pieces.

Vorzugsweise ist der Schraubenbolzen zu diesem Zweck mit einem eine Verdrehung verhindernden Hammerkopf versehen.For this purpose, the screw bolt is preferably provided with a hammer head which prevents rotation.

Bei einer bevorzugten Ausführungsform der Erfindung wird jedes Ankerschienenstück durch zwei ineinanderliegende C-Profile gebildet, deren Stege aufeinanderliegen und deren abgewinkelte Schenkelenden eine Führung für den Schraubenbolzen bilden. Auf diese Weise können die Ankerschienenstücke aus einfachen und handelsüblichen Teilen preiswert hergestellt werden. Die zur Befestigung der Ankerschienenstücke entweder auf der Konsole oder auf einer Zarge bzw. einem Blendrahmen eines Fensters dienenden Schrauben werden vorzugsweise als Selbstschneideschrauben ausgebildet, so daß sich eine einfache und zuverlässige Montage ergibt.In a preferred embodiment of the invention, each anchor rail piece is formed by two interlocking C-profiles, the webs of which lie one on top of the other and whose angled leg ends form a guide for the screw bolt. In this way, the anchor rail pieces can be manufactured inexpensively from simple and commercially available parts. The screws used to fasten the anchor rail pieces either on the console or on a frame or frame of a window are preferably designed as self-tapping screws, so that simple and reliable assembly results.

Um größere Temperaturdifferenzen innerhalb der der Gebäudewand vorgestellten Fassade zu vermeiden, ist gemäß einem weiteren Merkmal der Erfindung die die Dämmschicht abdeckende Putzschicht als bewehrte, kunststoffvergütete Putzschicht ausgeführt und über die Konsole bzw. Fensterzarge geführt. Diese liegt somit innerhalb der Dämmschicht und kann auf besonders einfache Weise gegenüber innerhalb der Fassade angeordneten Fenstern abgedichtet werden, indem erfindungsgemäß zwischen der um die Zarge herumgeführten Putzschicht und einem sich anschließenden Blendrahmen eines Fensters ein Dichtungsband angeordnet wird.In order to avoid larger temperature differences within the facade presented to the building wall, according to a further feature of the invention the plaster layer covering the insulation layer is designed as a reinforced, plastic-coated plaster layer and guided over the console or window frame. This lies within the insulation layer and can be sealed in a particularly simple manner with respect to windows arranged inside the facade, in that, according to the invention, a sealing tape is arranged between the plaster layer which is guided around the frame and a subsequent window frame.

Mit der Erfindung wird schließlich vorgeschlagen, das Ankerschienenstück mit dem Befestigungselement durch vorzugsweise selbstschneidende Schrauben formschlüssig zu verbinden, die durch das Außen- und Innenteil hindurch in das äußere Ankerschienenstück geschraubt sind. Diese Schrauben stellen somit die formschlüssige Verbindung zwischen dem Befestigungselement und dem Ankerschienenstück her. Da diese Schrauben jeweils in ein nach der Ausrichtung des Befestigungselements zu bohrendes Loch eingeschraubt werden, können zuvor alle notwendigen Lagekorrekturen ausgeführt werden. Das Einbringen dieser Bohrungen durch in den Befestigungselementen bereits vorhandene Löcher in die Ankerschienenstücke stellt die einzige Bohrarbeit dar, die auf dem Gerüst bei Anbringen der Fassadenelemente durchgeführt werden muß; alle anderen Bearbeitungen können bereits in der Werkstatt vorgenommen werden.Finally, the invention proposes to form-fit the anchor rail piece to the fastening element by means of preferably self-tapping screws are screwed through the outer and inner part into the outer anchor rail piece. These screws thus establish the positive connection between the fastening element and the anchor rail piece. Since these screws are each screwed into a hole to be drilled after the fastener has been aligned, all necessary position corrections can be carried out beforehand. The introduction of these holes through holes already present in the fastening elements in the anchor rail pieces represents the only drilling work that has to be carried out on the scaffolding when the facade elements are attached; all other processing can already be done in the workshop.

Die Fig. 1 zeigt die Teilansicht eines 5-stöckigen Gebäudes, dessen vier Obergeschosse mit einer Fassadenverkleidung aus plattenförmigen Fassadenelementen 1 versehen sind. Diese plattenförmigen Fassadenelemente 1 sind großflächig sowohl in waagerechter Richtung zwischen Fenstern 2 eines Geschosses als auch in senkrechter Richtung zwischen den Fenstern 2 übereinanderliegender Stockwerke angeordnet. Jedes Fassadenelement 1 wird normalerweise durch vier Befestigungselemente 3 getragen, die jeweils an einem Tragelement 4 befestigt werden, das seinermit der Gebäudewand 5 verbunden ist. Die Fassadenelemente 1 bestehen beispielsweise aus emaillierten und vorgespannten Glasscheiben.In the drawing, an embodiment of the fastening device according to the invention for plate-shaped facade elements is shown, namely:

Fig. 3
a perspective view of such an attachment point before assembly.
1 shows the partial view of a 5-storey building, the four upper floors of which are provided with a facade cladding made of plate-shaped facade elements 1. These plate-shaped facade elements 1 are arranged over a large area both in the horizontal direction between windows 2 of a floor and in the vertical direction between the windows 2 of superposed floors. Each facade element 1 is normally supported by four fastening elements 3, each of which is fastened to a supporting element 4, which is thus the building wall 5 is connected. The facade elements 1 consist, for example, of enamelled and toughened glass panes.

Wie aus den Fig. 2 und 3 hervorgeht, wird das Tragelement 4 durch ein Ankerschienenstück 6 gebildet, das beim Ausführungsbeispiel durch zwei ineinanderliegende C-Profile 6a und 6b gebildet wird, deren Stege aufeinanderliegen und deren abgewinkelte Schenkelenden eine durch einen Schlitz getrennte Führung 7 bilden. In dieser Führung 7 ist ein Schraubenbolzen 8 verschiebbar geführt, der beim Ausführungsbeispiel mit einem Hammerkopf 8a versehen und auf diese Weise unverdrehbar am Ankerschienenstück 6 geführt ist.As can be seen from FIGS. 2 and 3, the support element 4 is formed by an anchor rail piece 6, which in the exemplary embodiment is formed by two C-profiles 6a and 6b lying one inside the other, the webs of which lie on one another and the angled leg ends of which form a guide 7 separated by a slot . In this guide 7, a screw bolt 8 is slidably guided, which in the exemplary embodiment is provided with a hammer head 8a and is guided non-rotatably on the anchor rail piece 6 in this way.

Jedes Befestigungselement 3 besteht aus einem Außenteil 3a und einem Innenteil 3b, die gemeinsam auf dem Schraubenbolzen 8 angeordnet werden, wie dies am besten die Fig. 3 zeigt. Hiernach ist jedes Außenteil 3a mit einer Aufstandsfläche für ein plattenförmiges Fassadenelement 1 versehen. Diese Aufstandsfläche kann alternativ auch am Innenteil 3b ausgebildet sein. Beim Ausführungsbeispiel wird die Aufstandsfläche am Außenteil 3a durch mehrfaches Verkröpfen des Außenteils 3a geschaffen. Die Verkröpfung wird hierbei mit einer Tiefe ausgeführt, die der Dicke des jeweils zu befestigenden Fassadenelements 1 im Bereich seiner Aufstandskante entspricht. Die Höhe der Verkröpfung entspricht dem Abstand der jeweils benachbarten Fassadenelemente 1, d.h. der zwischen benachbarten Fassadenelementen 1 gebildeten Fuge.Each fastening element 3 consists of an outer part 3a and an inner part 3b, which are arranged together on the screw bolt 8, as best shown in FIG. 3. According to this, each outer part 3a is provided with a contact surface for a plate-shaped facade element 1. This contact surface can alternatively also be formed on the inner part 3b. In the exemplary embodiment, the contact area on the outer part 3a is created by repeatedly cranking the outer part 3a. The cranking is carried out with a depth that corresponds to the thickness of the facade element 1 to be fastened in the region of its rising edge. The height of the offset corresponds to the distance between the adjacent facade elements 1, i.e. the joint formed between adjacent facade elements 1.

Oberhalb und unterhalb der Aufstandsfläche bildet jedes Außenteil 3a eine Anlagefläche für das obere und für das untere Fassadenelement 1. Während die Last des jeweils auf dem Außenteil 3a aufstehenden Fassadenelements 1 über die Aufstandsfläche aufgenommen wird, tragen die Anlageflächen die auf die Fassadenelemente 1 ausgeübten Windkräfte ab, und zwar über den Schraubenbolzen 8 in die Ankerschienenstücke 6, die ihrerseits an der Gebäudewand 5 befestigt sind.Above and below the footprint, each outer part 3a forms a contact surface for the upper and for the lower facade element 1. While the load of the facade element 1 standing on the outer part 3a is absorbed by the contact surface, the contact surfaces absorb the wind forces exerted on the facade elements 1 , via the Bolts 8 in the anchor rail pieces 6, which in turn are attached to the building wall 5.

Diese Befestigung der Ankerschienenstücke 6 erfolgt mittels zweier Schrauben 9 an einer Konsole 10, die beim Ausführungsbeispiel einen T-förmigen Querschnitt hat und ihrerseits durch Befestigungswinkel 11 an der Gebäudewand 5 befestigt ist. Um eine thermische Trennung zwischen der Konsole 10 und der Gebäudewand 5 zu erreichen, sind zwischen den Befestigungswinkeln 11 und der Konsole 10 Zwischenlagen 12, vorzugsweise aus Kunststoff angeordnet. Wie insbesondere Fig. 3 erkennen läßt, liegen die Konsolen 10 innerhalb einer Wärmedämmung 13. Sie sind außerdem durch eine Putzschicht 14 abgedeckt, die vorzugsweise als bewehrte, kunststoffvergütete Putzschicht ausgeführt ist und um den jeweils freien Schenkel des T-förmigen Profils der Konsole 10 herumgeführt ist, wie die Fig. 2 und 3 zeigen.This fastening of the anchor rail pieces 6 takes place by means of two screws 9 on a bracket 10, which in the exemplary embodiment has a T-shaped cross section and is in turn fastened to the building wall 5 by fastening brackets 11. In order to achieve a thermal separation between the bracket 10 and the building wall 5, intermediate layers 12, preferably made of plastic, are arranged between the fastening angles 11 and the bracket 10. As can be seen in particular in FIG. 3, the brackets 10 are located within thermal insulation 13. They are also covered by a plaster layer 14, which is preferably designed as a reinforced, plastic-coated plaster layer and is guided around the free leg of the T-shaped profile of the bracket 10 is as shown in FIGS. 2 and 3.

Bei dem in den Fig. 2 und 3 dargestellten Ausführungsbeispiel ist die Konsole 10 gleichzeitig Zarge von einem Fenster 2, das einen Flügelrahmen 2a und einen Blendrahmen 2b umfaßt, der mittels Blendleiste 2c in der Fensteröffnung der Gebäudewand 5 eingebaut ist. Um eine zuverlässige Abdichtung der Putzschicht 14 gegenüber dem Blendrahmen 2b des Fensters 2 zu erzielen, ist zwischen diesen beiden Teilen ein Dichtungsband 15 angeordnet.In the embodiment shown in FIGS. 2 and 3, the console 10 is simultaneously the frame of a window 2, which comprises a casement 2a and a window frame 2b, which is installed in the window opening of the building wall 5 by means of a window strip 2c. In order to achieve a reliable seal of the plaster layer 14 with respect to the window frame 2b of the window 2, a sealing tape 15 is arranged between these two parts.

Um die aus dem Gewicht der Fassadenelemente 1 herrührenden Traglasten durch Formschluß in das Ankerschienenstück 6 einzuleiten, werden Schrauben 16 verwendet, die in Fig. 3 zu erkennen sind. Diese vorzugsweise selbstschneidend ausgeführten Schrauben 16 werden in Löcher 6c eingeschraubt, die in das Ankerschienenstück 6 gebohrt werden, nachdem das Befestigungselement 3 durch Verschieben des Schraubenbolzens 8 in der Führung 7 ausgerichtet worden ist. Die von den auf der Aufstandsfläche des Außenteils 3a aufstehenden Fassadenelementen 1 herrührenden Traglasten werden somit formschlüssig über die auf Scherung belasteten Schrauben 16 in das Ankerschienenstück 6 eingeleitet, wobei eine beispielsweise als Gerüstöse ausgebildete Ringösenmutter 17 dafür sorgt, daß das aus Außenteil 3a und Innenteil 3b bestehende Befestigungselement 3 an das als Tragelement 4 dienende Ankerschienenstück 6 angepreßt wird. Eine glattwandige Hülse 18 wird als Abstandshülse verwendet.In order to introduce the loads resulting from the weight of the facade elements 1 into the anchor rail piece 6 by positive locking, screws 16 are used, which can be seen in FIG. 3. These preferably self-tapping screws 16 are screwed into holes 6c which are drilled in the anchor rail piece 6 after the fastening element 3 has passed through Moving the bolt 8 has been aligned in the guide 7. The payloads originating from the contact surface of the outer part 3a are thus positively introduced into the anchor rail piece 6 via the screws 16 subjected to shear, an annular eyelet nut 17, for example, designed as a scaffold eyelet, ensuring that the outer part 3a and inner part 3b consist of the outer part Fastening element 3 is pressed onto the anchor rail piece 6 serving as the supporting element 4. A smooth-walled sleeve 18 is used as a spacer sleeve.

Wie die Zeichnungen deutlich erkennen lassen, liegen die als Tragelemente 4 dienenden kurzen Ankerschienenstücke 6, die in der Praxis eine Länge von etwa 10 cm haben, zwar atmosphärisch frei; sie stellen jedoch kein Probelm bei Temperaturänderungen oder Temperaturunterschieden zwischen der Gebäudewand 5 und den Fassadenelementen 1 dar, weil sie einerseits kurz sind und andererseits für jeden Befestigungspunkt separat entweder über Konsolen bzw. Zargen 10 oder Blendrahmen 2b an der Gebäudewand 5 befestigt sind. Sofern Konsolen oder Zargen 10 verwendet werden, liegen diese einschließlich ihrer Befestigungswinkel 11 innerhalb der Wärmedämmung 13 und unterhalb der Putzschicht 14.As can be clearly seen in the drawings, the short anchor rail pieces 6 serving as support elements 4, which in practice have a length of about 10 cm, are exposed to the atmosphere; however, they do not constitute a problem with temperature changes or temperature differences between the building wall 5 and the facade elements 1 because, on the one hand, they are short and, on the other hand, they are fastened separately to the building wall 5 either via brackets or frames 10 or frame 2b. If brackets or frames 10 are used, these, including their fastening angles 11, lie within the thermal insulation 13 and below the plaster layer 14.
