Abstract

A freely movable fastening device allows for changes in the length of façade elements (12) due to humidity and temperature variations. Thanks to telescopic lockable consoles (3), the mounting clearances between the outer wall (1) of a building, the supporting rail (2) and a fastening strip (6) that extends parallel to the outer wall (1) of the building are adjusted and corrected. In order to support the fastening strip (6) and the façade elements (12), the mobility of the consoles (3) in the supporting rail (2) is limited by a stop (16).

Description

Die Erfindung betrifft eine Befestigungsvorrichtung für Fassadenelemente (Fassadenplatten) von Bauten, die als äussere Schale zwecks Wetterschutz der Wärmeisolation der Gebäudeaussenwand dienen und nebst Eigengewicht, das Gewicht der Fassadenplatten, und die aus Druck und Unterdruck der Windlast resultierende statische und dynamische Last an die Gebäudeaussenwand übertragen. Gegenstand der Erfindung ist somit eine Art Gerüstkonstruktion, die als Befestigungsgrundlage für die Fassadenelemente notwendig ist.The invention relates to a fastening device for facade elements (facade panels) of buildings that serve as an outer shell for the purpose of weather protection of the thermal insulation of the building's outer wall and, in addition to their own weight, the weight of the facade panels, and the static and dynamic load resulting from the pressure and negative pressure of the wind load are transmitted to the building's outer wall . The invention thus relates to a type of scaffold construction that is necessary as a fastening base for the facade elements.

Aus der DE-A-1 811 451 ist eine Befestigungsvorrichtung für Fassadenplatten bekannt, die ein Maueranker ist und aus einem einstückigen T-förmig gestalteten Halteelement besteht und je nach Bedarf den Abstand zwischen der tragenden Wand und den aufzuhängenden Fertigbauelementen einzustellen gestattet um eine Mauerdurchfeuchtung zu vermieden.From DE-A-1 811 451 a fastening device for facade panels is known, which is a wall anchor and consists of a one-piece T-shaped holding element and, depending on requirements, allows the distance between the load-bearing wall and the prefabricated elements to be suspended, in order to allow the walls to be moistened avoided.

Bei anderen bekannten Konstruktionen wird an die Gebäudeaussenflache als Tragschiene ein Winkel- oder T-Profil mit der Höchstlänge von 6 m angeschraubt, so dass ein Schenkel von der Wand absteht. Als Befestigungssteg für die Fassadenelemente wird ebenfalls ein Winkel- oder T-Profil verwendet. Nach Anbau der Isolation an die Gebäudeaussenwand werden die freistehenden Schenkel vom Befestigungssteg und der Tragschiene miteinander so verbunden, dass sie an der Gebäudeaussenwand ein verbleibendes Traggerüst für die Aufnahme der Fassadenelemente und mit diesen eine ausreichend stetige Aussenfläche des Baukör pers bilden. Um diese Aufgabe ohne separate Justiervorrichtungen zu lösen, hat man in der EP-0 005 937 B1 die provisorische Befestigung an der Tragschiene mit integrierten Federelemten des Befestigungssteges vorgeschlagen.In other known constructions, an angle or T-profile with a maximum length of 6 m is screwed onto the outer surface of the building as a mounting rail, so that one leg protrudes from the wall. An angle or T-profile is also used as a fastening bar for the facade elements. After attaching the insulation to the outer wall of the building, the free-standing legs are removed from the fastening web and the mounting rail connected to each other so that they form a remaining supporting structure on the outer wall of the building for receiving the facade elements and with them a sufficiently continuous outer surface of the building body. In order to solve this problem without separate adjustment devices, provisional attachment to the mounting rail with integrated spring elements of the fastening web has been proposed in EP-0 005 937 B1.

Wesentlicher Nachteil dieser Konstruktionen ist das ungelöste Problem der Befestigung der Fassadenelemente wegen der aussentemperatur- und feuchtebedingten Längenveränderung der Fassadenplatten. Weiterer Nachteil herkömlicher Konstruktionen ist die arbeitsintensive Justierung mit endgültiger Fix-ierung an der Baustelle und dass dazu für die Erstellung der Montagelöcher Maschineneinsatz notwendig ist. Schliesslich ist auf die Bildung von Kältebrücken - mit allen unliebsamen Wärmeverlusten und bauphysikalischen Folgen - durch die Unterbrechung der Isolation und durch grossflächige Berührung der Tragschiene und des Befestigungssteges hinzuweisen.A major disadvantage of these constructions is the unsolved problem of fastening the facade elements due to the change in length of the facade panels due to outside temperature and moisture. Another disadvantage of conventional constructions is the labor-intensive adjustment with final fixation at the construction site and the fact that machine use is necessary to create the assembly holes. Finally, the formation of cold bridges - with all the unpleasant heat losses and structural consequences - is to be pointed out by interrupting the insulation and by touching the mounting rail and the fastening web over a large area.

Ein Vorschlag mit anpassungsfähigerer Befestigung stellt die Konstruktion mit einem an die Gebäudeaussenwand geschraubtem "V"-förmigem Befestigungsstück, gemäss EP 0 067 970 B1, mit zwei geschlitzten Schenkeln und in diese Schlitze greifende und mit dem Befestigunssteg fest verbundenen Verbindungsstück dar. Die Befestigungsstücke werden dann so montiert, dass sich übereinander Fest- und Gleitpunkte ergeben, also Stellen, wo die in die Schlitze des Befestigungsstückes greifende Verbindungsstücke keine oder aber eine gewisse Verschiebung erlauben. Wegen der ausgezeichneten Korrosionsresistenz und der günstigen gewichtsbezogenen Festigkeit hat sich für die Tragkonstruktion trotz des grossen Ausdehnungskoeffizienten die Aluminiumlegierung AlMgSi1 durchgesezt. Die Verdrängung der asbesthaltigen Fassadenplatten durch physiologisch unbedenkliche Werkstoffe (Aluminiumsandwich, Glasfaserzement, Kermaik, Kunstharz, Polyesterbeton,) hat zugleich die Anforderungen des Dilatationsproblems erhöht. So werden herkömmliche Konstruktionen den Bedürfnissen der Zukunft kaum gerecht.A proposal with more adaptable fastening is the construction with a "V" -shaped fastening piece screwed to the outer wall of the building, in accordance with EP 0 067 970 B1, with two slotted legs and connecting pieces which reach into these slots and are firmly connected to the fastening web. The fastening pieces are then mounted in such a way that there are fixed and sliding points on top of each other, i.e. places where the connecting pieces that engage in the slots of the fastening piece do not allow any or only a certain displacement. Due to the excellent corrosion resistance and the favorable weight-related strength, the aluminum alloy AlMgSi1 has prevailed for the supporting structure despite the large expansion coefficient. The displacement of the asbestos-containing facade panels by physiologically harmless materials (aluminum sandwich, glass fiber cement, ceramic, synthetic resin, polyester concrete,) has also increased the requirements of the dilation problem. In this way, conventional constructions hardly meet the needs of the future.

Die vorliegende Erfindung stellt sich die Aufgabe, die genannten Nachteile zu beseitigen.The object of the present invention is to eliminate the disadvantages mentioned.

Erfindungsgemäss wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.According to the invention, this object is achieved by the characterizing features of claim 1.

Durch die erfindungsgemässe Befestigungsvorrichtung wird ein optimales Dilatationsverhalten der Fassadenkonstruktion erreicht. Durch die erfindungsgemässe Befestigungsvorrichtung vereinfacht sich die Herstellung der selben dadurch, dass alle Teile massgeschnitten und mit sämtlichen Durchbrüchen versehen bei der werkmässigen Vorfertigung serienmässig hergestellt und Bearbeitungen - wie Löcher und Schlitze - an Stelle von spahnabhebenden Verfahren gestanzt werden können.An optimal dilatation behavior of the facade construction is achieved by the fastening device according to the invention. Through the fastening device according to the invention The manufacture of the same is simplified by the fact that all parts are custom-made and provided with all the openings in the factory prefabrication and machining - such as holes and slots - can be punched instead of using a machining process.

Durch die erfindungsgemässe Befestigungsvorrichtung vereinfacht sich die Montage der selben dadurch, dass die Teile nicht nur fertig bearbeitet sondern vormontiert an die Baustelle kommen. Mit Ausnahme der Befestigung der Tragschienen an die Gebäudeaussenwand werden die übrigen Teile durch einfaches Stecken gefügt und duch Anziehen der Schrauben befestigt. Da die Schraubverbindungen sinnvollerweise vormontiert sind und für die Montage nicht mehr auseinandergenommen werden müssen, bleiben die Kleinteile der Erfindung vom Verlust durch-Verlohren-gehen-an-der-Baustelle weitgehend verschohnt.Due to the fastening device according to the invention, the assembly of the same is simplified in that the parts not only arrive at the construction site but are pre-assembled. With the exception of the fastening of the mounting rails to the outer wall of the building, the remaining parts are simply joined and fastened by tightening the screws. Since the screw connections are usefully preassembled and no longer have to be disassembled for assembly, the small parts of the invention are largely spared from being lost by being lost at the construction site.

Zusätzlicher Vorteil der erfindungsgemässen Vorrichtung ist, dass die Wandbefestigung der Tragschiene als Anschlag der Konsole dient.An additional advantage of the device according to the invention is that the wall fastening of the mounting rail serves as a stop for the console.

Ein weiterer Vorteil der erfindungsgemässen Vorrichtung liegt in der Vermeidung von Kältebrücken entlang der Tragschiene, da diese Dank flacher Konzeption sich für die Integration in der Isolation eignet.A further advantage of the device according to the invention lies in the avoidance of cold bridges along the mounting rail, since, thanks to the flat design, it is suitable for integration in the insulation.

Ein weiterer Vorteil der erfindungsgemässen Befestigungsvorrichtung besteht in die Längenverstellbarkeit der Konsole. Dank dem wird die Aufnahme von grösseren Gebäudetoleranzen bei der Montage möglich.
Schliesslich; dank dem, dass die Konsole sich in der "T"-förmigen Längsnut der Tragschiene verschieben kann, eignet sich die Befestigungsvorrichtung hervorragend für die Aufnahme der von der Aussentemperatur und der Feuchte bedingten Längenausdehnung der Fassadenplatten.
Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

In Figur 1 und 2 sind zwei Fassadenelemente 12 von der Gebäudeseite hergesehen dargestellt. Sie sind mit nicht dargestellten Mitteln am senkrechten Befestigungssteg 6 befestigt. Die Rückseite des senkrechten Befestigungsstegs 6 ist mit einer seitlich offenen "T"-förmigen Längsnut 6' zur Aufnahme einer Hammerschraube 7 versehen, die zur Befestigung des als T-Nutprofil geformten Verlängerungstücks 10 der verstellbaren Konsole 3 dient. Diese verstellbare Konsole 3 wird aus dem Träger 8 und aus dem Verlängerungsstück 10 zusammengesetzt, wobei der Träger 8 vorteilhafterweise als T-Profil geformt ist, dessen Schenkel in die T-Nut des Verlängerungstücks 10 hineinragt, und sein Flansch als Fuss 8' der verstellbaren Konsole 3 in der "T"-förmigen Längsnut der Tragschiene 2' befindet. Im Träger 8 ist ein Durchgangsloch 8'' und in der Verlängerung 10'' ein Durchgangsloch 10'' vorhanden. Durch den Durchgangsloch 10 wird die Hammerschraube 7 gesteckt und die Verlängerung 10 an die Befestigung festgeschraubt. Dabei ist wesentlich, dass der Kopf der Hammerschraube 7 nur so breit wie die Oeffnung der "T"-förmigen Längsnut 6' des senkrechten Befestigungsstegs 6 ist, damit diese an beliebigen Stellen in dieser Nut eingelegt und damit die Hammerschraube 7 auch in vormontiertem Zustand; - wenn sie durch das Durchgangsloch 10'' gesteckt ist und die Mutter 7' trägt,- eingehängt werden kann. Bei diesem "Einhängen" wird, sobald der Kopf der Hammerschraube 7 in die "T"-förmige Längsnut 6' einsenkt, die Mutter 7' angezogen, wobei die Gewindereibung die Hammerschraube 7 noch vor dem Zusammenpressen der verschraubten Teile 6;10, bis zum Anschlag der Kopf an die Seitenwände der "T"-förmigen Längsnut 6' dreht. Zum Anziehen, und zum Lösen der Schraubenverbindung - Hammerschraube 7 und Mutter 7'-braucht nur die Mutter 7' gedreht zu werden. Ein Gegenhalten der Schraube 7 erübrigt sich. Das gleiche gilt für die ebenfalls vormontierte Schraubenverbindung; Schraube mit Vierkantansatz 14 und Mutter 14', wo es um die Verstellung der Konsole 3 durch die Verschiebung der Vierkantansatzschraube im Schlitz 10' des Verlängerungsstükkes 10 und des Trägers 8 mit dem Durchgangsloch 8'' geht.
Wie die Fassadenelemente 12 mit waagrechtem Befestigungssteg 60, mit offenen "T"-förmigen Längsnut 60',einer Hammerschraube 7, der Befestigung des als T-Nutprofil geformten Verlängerungstück 100 der verstellbaren Konsole 3 dient zeigen die Figur 6 und 10.
Die Montage der Fassade beginnt mit dem Verlegen und Verschrauben der mit Konsolen 3 besetzten Tragschienen 2 mit Hilfe von Dübelschrauben 16 an die Gebäudeaussenwand 1. Dabei dient der Kopf der Dübelschraube 16 als Anschlag 20 für die Konsole 3. Damit die Konsole 3 entsprechend Fig.3 und 6 beider Montage mit Sicherheit am Anschlag 20 sitzt, wird die Konsole 3 beispielsweise mit einem nicht gezeigten Gummiband in dieser Position gehalten. Danach folgt der Einbau der Isolation 11, die je nach Art und Gestaltung verschieden dick ist.
Zwischen die Isolation 11 und die Fassadenplatten 12 wird ein mehrerer Zentimeter dicker Raum offen gelassen. Dem entsprechend und entsprechend der Bautoleranzen wird der Wandabstand und der Abstand vom Fassadenanfang mit den verstellbaren Konsolen 3 eingestellt.Another advantage of the fastening device according to the invention is the length adjustability of the console. Thanks to this, it is possible to accommodate larger building tolerances during assembly.
In the end; thanks to the fact that the bracket can move in the "T" -shaped longitudinal groove of the mounting rail, the fastening device is excellently suited for absorbing the longitudinal expansion of the facade panels due to the outside temperature and humidity.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:

1 and 2 show two facade elements 12 seen from the building side. They are attached to the vertical fastening web 6 by means not shown. The back of the vertical fastening web 6 is provided with a laterally open "T" -shaped longitudinal groove 6 'for receiving a hammer screw 7, which serves to fasten the extension piece 10 of the adjustable bracket 3 which is shaped as a T-groove profile. This adjustable bracket 3 is composed of the support 8 and the extension piece 10, the support 8 advantageously being shaped as a T-profile, the leg of which projects into the T-groove of the extension piece 10, and its flange as the foot 8 'of the adjustable console 3 is located in the "T" -shaped longitudinal groove of the mounting rail 2 '. There is a through hole 8 ″ in the carrier 8 and a through hole 10 ″ in the extension 10 ″. The hammer screw 7 is inserted through the through hole 10 and the extension 10 is screwed onto the fastening. It is essential that the head of the hammer screw 7 is only as wide as the opening of the "T" -shaped longitudinal groove 6 'of the vertical fastening web 6 so that it is inserted at any point in this groove and thus also the hammer screw 7 pre-assembled condition; - If it is inserted through the through hole 10 '' and carries the nut 7 ', - can be hung. In this "hanging", as soon as the head of the hammer screw 7 sinks into the "T" -shaped longitudinal groove 6 ', the nut 7' is tightened, with the thread rubbing the hammer screw 7 before the screwed parts 6; 10 are pressed together until Stop the head on the side walls of the "T" -shaped longitudinal groove 6 'rotates. To tighten and loosen the screw connection - hammer screw 7 and nut 7 '- only the nut 7' needs to be turned. There is no need to hold the screw 7 in place. The same applies to the pre-assembled screw connection; Screw with square neck 14 and nut 14 ', where it is about the adjustment of the bracket 3 by moving the square neck screw in the slot 10' of the extension piece 10 and the carrier 8 with the through hole 8 ''.
6 and 10 show how the facade elements 12 with a horizontal fastening web 60, with an open “T” -shaped longitudinal groove 60 ′, a hammer screw 7, serve to fasten the extension piece 100, which is shaped as a T-groove profile, of the adjustable bracket 3.
The assembly of the facade begins with the laying and screwing of the mounting rails 2 with brackets 3 to the outer wall 1 of the building with the aid of dowel screws 16 the head of the dowel screw 16 serves as a stop 20 for the console 3. So that the console 3 sits securely on the stop 20 according to FIGS. 3 and 6 during assembly, the console 3 is held in this position, for example with a rubber band, not shown. This is followed by the installation of the insulation 11, which is of different thickness depending on the type and design.
A space several centimeters thick is left open between the insulation 11 and the facade panels 12. Correspondingly and in accordance with the construction tolerances, the wall distance and the distance from the beginning of the facade are set with the adjustable brackets 3.

Das betriebliche Verhalten der Fassadenkonstruktion ist durch die Gegenüberstellung der Anordnung von normalen, (Fig.3 und 8) erhöhten (Fig.4 und 9) und Tiefsttemperaturen (Fig.5 und 10) ersichtlich.The operational behavior of the facade construction can be seen by comparing the arrangement of normal (Fig. 3 and 8) elevated (Fig. 4 and 9) and minimum temperatures (Fig. 5 and 10).

Bei gestiegener Temperatur dehnt sich der senkrechte Befestigungssteg 6 und die Fassadenplatten 12 bis 12'' und verschieben sich die Konsolen 3',3'' und 3''' aufwärts. Deshalb heben sich mit Ausnahme der untersten Konsole 3 die übrigen Konsolen 3',3'',3''' von den Anschlägen 16'bis 16'''ab und die Fassadenkonstruktion stützt mit ihrem gesamten Gewicht auf den Anschlag 16. Bei tieferen Temperaturen (vgl.Fig.5 und 10) als die Montagetemperatur (vgl.Fig.3 und 8),verkürzt sich der senkrechte Befestigungssteg 6 und die Fassadenplatten 12 bis 12''. Deshalb wird das Gewicht der Fassadenkonstruktion auf den Anschlag 16''' der Konsole 3''' aufgehängt. Es versteht sich, dass die gesamte Konstruktion einer Fassade aus mehreren parallelen Sektionen entsprechend der Fig.3 und 8 besteht und dass das in der Fig.3 bis 5 gezeigte Prinzip der Abstützung resp. Aufhängung als Lagerung auch mit waagrechten Befestigungsstegen in beliebiger weise durch das Weglassen oder den Einsatz von Anschlägen 16 und durch die Kombination derselben mit losen und mit festen Konsolen 3 variiert werden kann.
Wichtig ist, dass Dank der vorgeschlagenen Befestigungsvorrichtung bei der Applikation verschiedenster Fassadenplatten 12 die Berücksichtigung der Linearenausdehnung und Schrumpfung der selben vollständig vernachlässigt werden kann.
Als Beispiel sei für die Auslegung der Fall erwähnt, wenn von der Kette losen Konsolen 3 (n) nur eine Konsole 3 (n-x) mit einem Anschlag 16 (n-x) ausgerüstet wird Dann stützt sich die oberhalb befindliche Konstruktion auf diese Konsole 3, während die darunter sich befindliche daran hängt. Im Gegensatz zu der Festigkeitsbelastung und somit der Auslegung des senkrechten Befestigungsstegs 6 und der Fassadenplatten 12 hat die Umverteilung der Belastung auf die Konsole 3 (n-x) keinen Einfluss. Für die optimale Gestaltung der Konstruktion wird daher nebst Berücksichtigung der Windlasten die Assymetrie der Zug und Druckdauerfestigkeit der Werkstoffe des senkrechten Befestigungsstegs 6 und der Fassadenplatten 12 massgebend sein.When the temperature rises, the vertical fastening web 6 and the facade panels 12 to 12 ″ expand and the brackets 3 ′, 3 ″ and 3 ″ ″ move upwards. Therefore, with the exception of the bottom bracket 3, the remaining brackets 3 ', 3'',3''' stand out from the stops 16 'to 16''' and the facade structure is supported with its entire weight on the stop 16. At lower temperatures (see Figures 5 and 10) than the assembly temperature (see Figs. 3 and 8), the vertical fastening web 6 and the facade panels 12 to 12 '' are shortened. The weight of the facade construction is therefore suspended on the stop 16 '''of the bracket 3'''. It goes without saying that the entire construction of a facade consists of several parallel sections corresponding to FIGS. 3 and 8 and that the principle of the support shown in FIGS. Suspension as storage can also be varied with horizontal fastening webs in any manner by omitting or using stops 16 and by combining them with loose and with fixed brackets 3.
It is important that, thanks to the proposed fastening device, the consideration of the linear expansion and shrinkage of the same can be completely neglected when applying a wide variety of facade panels 12.
As an example for the design, the case should be mentioned if only one bracket 3 (nx) of the chain-less brackets 3 (n) is equipped with a stop 16 (nx). Then the above structure is supported on this bracket 3, while the depends on it. In contrast to the strength load and thus the design of the vertical fastening web 6 and the facade panels 12 the redistribution of the load on console 3 (nx) has no influence. In addition to taking the wind loads into account, the asymmetry of the tensile and compressive fatigue strength of the materials of the vertical fastening web 6 and the facade panels 12 will be decisive for the optimal design of the construction.

Zu erwähnen ist, dass zwecks Reduktion der Werzeugkosten der Vorrichtungselemte die Querschnitte der Tragschiene 2 und des Verlängerungsstücks 10 identisch sein können.It should be mentioned that, in order to reduce the tool costs of the device elements, the cross sections of the mounting rail 2 and of the extension piece 10 can be identical.
