Description

Die Erfindung betrifft eine Befestigungsvorrichtung für Fassadenelemente an einer Gebäudeaußenwand, bei der ein von der Gebäude-' außenwand winkelig abstehendes und mit der Gebäudeaußenwand durch eine Schraube o. dgl. verbundenes flächiges Verbindungsstück an einer entsprechend winkelig stehenden Befestigungsleiste des Fassadenelements flächig anliegt und durch übliche Verbindungsmittel mit der Befestigungsleiste verbindbar ist.The invention relates to a fastening device for facade elements on an outer wall of a building, in which a flat connector protruding from the outer wall of the building and connected to the outer wall of the building by a screw or the like lies flat against a correspondingly angled fastening strip of the facade element and by conventional connecting means can be connected to the fastening strip.

Bei den aus der DE-OS 28 24 902 bekannten Befestigungsvorrichtung stellt das flächige Verbindungsstück einen Teil eines Winkelprofils dar, dessen anderer Schenkel flächig an der Gebäudeaußenwand liegt und mittels einer Schraube-Dübel-Verbindung an der Gebäudeaußenwand befestigt wird. Bekanntlich muß die Dimensionierung der Befestigungsvorrichtungen so erfolgen, daß die Fassadenplatten, die über die Befestigungsleiste mit der Befestigungsvorrichtung verbunden sind, bei allen auftretenden Belastungen sicher gehalten werden. Die wesentlichste in Betracht zu ziehende Belastung ist die sogenannte "Windsog-und -druckbelastung", durch die eine Zug- oder Druckkraft aus den Fassadenplatten auf die Gebäudeaußenwand erzeugt wird. Diese Kräfte übertragen sich über das flächige Verbindungsstück bei der bekannten Befestigungsvorrichtung auf den an der Gebäudeaußenwand anliegenden Schenkel und werden über die diesen Schenkel befestigende Schraube in die Gebäudeaußenwand eingeleitet.In the fastening device known from DE-OS 28 24 902, the flat connecting piece is part of an angular profile, the other leg of which lies flat on the outer wall of the building and is fastened to the outer wall of the building by means of a screw-dowel connection. As is known, the dimensioning of the fastening devices must take place in such a way that the facade panels, which are connected to the fastening device via the fastening strip, are securely held under all occurring loads. The most important load to be considered is the so-called "wind suction and pressure load", by means of which a tensile or compressive force is generated from the facade panels on the outer wall of the building. These forces are transmitted through the flat connector in the known fastening device on the leg abutting the outer wall of the building and are introduced into the outer wall of the building via the screw fastening this leg.

Der Erfindung liegt die Erkenntnis zugrunde, daß bei einer derartigen exzentrischen Krafteinleitung in die Gebäudeaußenwand ein zusätzliches Drehmoment und aus dem Verhältnis der Hebelarme am Dübel eine zusätzliche Zugkraft entsteht, wodurch die auf die Schraube wirkende Kraft etwa doppelt so hoch ist wie die an sich auftretende Windsogbelastung. Diesen erhöhten Kräften muß durch eine entsprechende Auslegung der Befestigungsvorrichtungen bzw. durch eine Erhöhung der Anzahl der Befestigungsvorrichtungen pro Fassadenfläche Rechnung getragen werden, wodurch die Kosten für die Unterkonstruktion der Fassaden beträchtlich erhöht werden.The invention is based on the finding that, with such an eccentric introduction of force into the outer wall of the building, an additional torque and an additional tensile force arises from the ratio of the lever arms on the dowel, as a result of which the force acting on the screw is approximately twice as high as the wind suction load per se . These increased forces must be taken into account by appropriately designing the fastening devices or by increasing the number of fastening devices per facade surface, which considerably increases the costs for the substructure of the facades.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Befestigungsvorrichtung zu erstellen, bei der die Krafteinleitung in die Gebäudeaußenwand günstiger erfolgt und damit der Aufwand für die Unterkonstruktion verringert werden kann.In contrast, the invention is based on the object of creating a fastening device in which the introduction of force into the outer wall of the building takes place more cheaply and thus the effort for the substructure can be reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Gebäudeaußenwand mittels der Schraube o. dgl. ein Befestigungsstück mit zwei Schenkeln befestigt ist, die im wesentlichen in einer Achse mit dem Befestigungspunkt angebracht sind und daß das flächige Verbindungsstück mit den beiden Schenkeln verbunden ist.This object is achieved in that a fastening piece with two legs is attached to the outer wall of the building by means of the screw or the like, which are attached essentially in one axis to the fastening point and that the flat connecting piece is connected to the two legs.

Bei der erfindungsgemäßen Befestigungsvorrichtung wird die durch die Windsog- und -druckbelastung auftretende Kraft zentrisch an der Schraube o. dgl. in die Gebäudeaußenwand eingeleitet. Die durch die Hebelwirkung bei den bekannten Befestigungsvorrichtungen entstehenden Kräfte treten daher bei der erfindungsgemäßen Befestigungsvorrichtung nicht auf. Die erfindungsgemäße Befestigungsvorrichtung bietet den weiteren Vorteil, daß sie sich einfach montieren und handhaben läßt, wobei sie im allgemeinen aus zwei separaten Teilen besteht, die miteinander verbunden worden sind.In the fastening device according to the invention, the force occurring due to the wind suction and pressure load is introduced centrally into the outer wall of the building at the screw or the like. The forces resulting from the lever effect in the known fastening devices therefore do not occur in the fastening device according to the invention. The invention Fastening device has the further advantage that it is easy to assemble and handle, generally consisting of two separate parts which have been connected together.

Prinzipiell wäre es auch denkbar, die zentrische Krafteinleitung dadurch zu realisieren, daß die bekannte Befestigungsvorrichtung nicht als Winkel, sondern als T-Profil ausgebildet wird und beiderseits des flächigen Verbindungsstücks eine Schraube vorgesehen ist. Eine derartige Anordnung hätte jedoch erhebliche Nachteile, da entsprechend den geltenden Bauvorschriften zwei Dübel in einer Gebäudeaußenwand einen Mindestabstand aufweisen müssen, so daß die Befestigungsvorrichtung relativ groß wird. Darüber hinaus müssen die Schrauben stabil aus korrosionsfreiem Material hergestellt werden, so daß sie selbst einen im Vergleich zur Befestigungsvorrichtung nicht vernachlässigbaren Kostenfaktor darstellen. Erfindungsgemäß wird daher angestrebt, die Befestigungsvorrichtung mit einer Schraube o. dgl. an der Gebäudeaußenwand festzulegen.In principle, it would also be conceivable to implement the central introduction of force in that the known fastening device is not designed as an angle, but rather as a T-profile and a screw is provided on both sides of the flat connecting piece. Such an arrangement would, however, have considerable disadvantages, since, according to the applicable building regulations, two dowels in an outer wall of the building must have a minimum distance, so that the fastening device becomes relatively large. In addition, the screws must be made stably from corrosion-free material, so that they themselves represent a cost factor that is not negligible compared to the fastening device. According to the invention, the aim is therefore to fix the fastening device to the outer wall of the building with a screw or the like.

Die Erfindung bietet besonders große Vorteile, wenn das Befestigungsstück und das flächige Verbindungsstück senkrecht zur Gebäudewand fest und parallel zur Gebäudewand mit Spiel verbunden sind. Fassaden, die naturgemäß starken thermischen Veränderungen ausgesetzt sind, werden mit sogenannten Fixpunkten und Gleitpunkten befestigt. Die Gleitpunkte erlauben eine Ausdehnung der Fassadenplatten parallel zur Gebäudeaußenwand, also in vertikaler Richtung. Sie halten jedoch die Fassadenplatten in der hierzu senkrechten Richtung, bieten also einen Widerstand gegen Winddruck- und Windsogkräfte. Mit der erfindungsgemäßen Befestigungsvorrichtung lassen sich die Gleitpunkte besonders gut realisieren, da die Gleitmöglichkeit in der Verbindung zwischen den beiden separaten Teilen der Befestigungsvorrichtung realisiert werden kann. Es ist also nicht erforderlich, Langlöcher o. ä. für diesen Zweck vorzusehen.The invention offers particularly great advantages if the fastening piece and the flat connecting piece are fixed perpendicularly to the building wall and are connected with play parallel to the building wall. Facades that are naturally exposed to strong thermal changes are fixed with so-called fixed points and floating points. The sliding points allow the facade panels to be extended parallel to the outer wall of the building, i.e. in the vertical direction. However, they keep the facade panels in the direction perpendicular to this, so they offer resistance to wind pressure and wind suction forces. The sliding points can be realized particularly well with the fastening device according to the invention, since the possibility of sliding can be realized in the connection between the two separate parts of the fastening device. It is therefore not necessary to prepare elongated holes or the like for this purpose see.

In einer bevorzugten Ausführungsform sind die Befestigungsflächen des flächigen Verbindungsstücks und die Schenkel des Befestigungsstücks in gleicher Richtung, also im allgemeinen vertikal, ausgerichtet. Dabei ist es vorteilhaft, wenn die Schenkel Schlitze aufweisen, in die Vorsprünge des flächigen Verbindungsstücks eingreifen.In a preferred embodiment, the fastening surfaces of the flat connecting piece and the legs of the fastening piece are aligned in the same direction, that is to say generally vertically. It is advantageous if the legs have slots into which protrusions of the flat connecting piece engage.

Die Montage der Befestigungsvorrichtung gestaltet sich besonders einfach, wenn die Schenkel von der Gebäudeaußenwand schräg auseinanderlaufen. In diesem Fall können die Vorsprünge in die etwas federnden Schenkel einschnappen. Diese Montage kann sowohl als Vormontage vor der Lieferung an die Baustelle als auch direkt an der Baustelle nach dem Befestigen des Befestigungsstücks an der Gebäudeaußenwand erfolgen.The mounting of the fastening device is particularly simple if the legs diverge diagonally from the outer wall of the building. In this case, the projections can snap into the somewhat resilient legs. This assembly can be carried out both as a pre-assembly before delivery to the construction site and directly at the construction site after the fastening piece has been attached to the outer wall of the building.

Befestigungsvorrichtungen für Unterkonstruktionen von Fassaden unterliegen oberen Preisgrenzen. Es ist deshalb erstrebenswert, die Befestigungsvorrichtungen möglichst aus endlosen Profilen herzustellen. Für die Befestigungsstücke läßt sich dies ohne weiteres realisieren, da ein endloses Profil mit den beiden Schenkeln herstellbar ist, von dem lediglich die Befestigungsstücke abgelenkt werden müssen. Die erfindungsgemäße Befestigungsvorrichtung bietet weiterhin den Vorteil, daß auch das flächige Verbindungsstück aus einem endlosen Bandmaterial hergestellt werden kann, daß es aus einem flachen Metallstück fertigbar ist. Hierfür ist es besonders vorteilhaft, wenn die Vorsprünge durch Ausnehmungen in dem Randbereich der Befestigungsfläche hergestellt sind, in die die freien Enden der Schenkel eingreifen. Die Vorsprünge können dann nämlich ohne Materialverlust beim Ausstanzen des flächigen Verbindungsstücks hergestellt werden.Fastening devices for substructures of facades are subject to upper price limits. It is therefore desirable to manufacture the fastening devices from endless profiles if possible. This can easily be achieved for the fastening pieces, since an endless profile with the two legs can be produced, from which only the fastening pieces need to be deflected. The fastening device according to the invention also has the advantage that the flat connecting piece can also be produced from an endless strip material, that it can be manufactured from a flat piece of metal. For this, it is particularly advantageous if the projections are made by recesses in the edge region of the fastening surface, into which the free ends of the legs engage. The projections can then be made without loss of material when punching out the flat connecting piece.

Da erfindungsgemäß das flächige Verbindungsstück aus Bandmaterial gestanzt werden kann, läßt sich der weitere Vorteil erreichen, daß unterschiedliche Abstände der Fassadenelemente von Gebäudeaußenwänden realisiert werden können, ohne daß hierzu verschiedene Profile für die Herstellung der Befestigungsvorrichtungen auf Lager gelegt werden müßten. Die Befestigungsstücke bleiben unverändert, während lediglich aus dem Bandmaterial ein flächiges Verbindungsstück mit einer anderen Länge ausgestanzt werden muß, wobei die verschiedenen flächigen Befestigungsstücke alle mit demselben Befestigungsstück verbindbar sind.Since, according to the invention, the flat connecting piece can be punched out of strip material, the further advantage can be obtained achieve that different distances between the facade elements of building outer walls can be realized without this having to put different profiles for the production of the fastening devices in stock. The fastening pieces remain unchanged, whereas only a flat connecting piece with a different length has to be punched out of the band material, the various flat fastening pieces all being connectable to the same fastening piece.

Vorzugsweise weist das flächige Verbindungsstück eine aus ihrem flächigen Material herausgearbeitete Klemmfeder auf, in die die Befestigungsleiste des Fassadenelements zum Vorjustieren einklemmbar ist, bevor die Befestigungsleiste endgültig mit dem flächigen Verbindungsstück durch Bolzen, Nieten o. dgl. verbunden wird. Auch dieser Vorgang kann beim Ausstanzen des flächigen Verbindungsstücks gleichzeitig vorgenommen werden, so daß sich die Herstellung der Befestigungsvorrichtung äußerst einfach gestaltet.The flat connecting piece preferably has a clamping spring worked out of its flat material, into which the fastening strip of the facade element can be clamped for pre-adjustment before the fastening strip is finally connected to the flat connecting piece by means of bolts, rivets or the like. This process can also be carried out simultaneously when punching out the flat connecting piece, so that the manufacture of the fastening device is extremely simple.

Die Montage wird erleichtert, wenn die Ausnehmungen und/oder die Vorsprünge eine Abschrägung aufweisen, die etwa der Schrägstellung der Schenkel des Befestigungsstücks entspricht.The assembly is made easier if the recesses and / or the projections have a bevel which corresponds approximately to the inclined position of the legs of the fastening piece.

Wenn die Befestigungsvorrichtung im vormontierten Zustand an die Baustelle geliefert wird, ist es vorteilhaft, wenn die Schraube einen Vielkant-Schraubenkopf aufweist, der durch zwei an dem Befestigungsstück angebrachte Leisten gegen Verdrehung gesichert ist. Durch das flächige Verbindungsstück ist die Schraube gegen eine axiale Verschiebung gesichert, so daß die Schraube durch Drehen der gesamten Befestigungsvorrichtung in den Dübel eingedreht werden kann.If the fastening device is delivered to the construction site in the preassembled state, it is advantageous if the screw has a polygonal screw head which is secured against rotation by two strips attached to the fastening piece. The flat connecting piece secures the screw against axial displacement, so that the screw can be screwed into the dowel by turning the entire fastening device.

Die Erfindung soll im folgenden an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The invention will be explained below with reference to an embodiment shown in the drawing.

Show it:
  • Fig. 1 - a side sectional view of a fastening device according to the invention
  • Fig. 2 - a top view of the fastening device according to FIG. 1 from above

In Fig. 1 ist ein Teil einer Gebäudeaußenwand 1 angedeutet, in die ein Dübel 2 eingesetzt ist. In den Dübel ist eine Schraube 3 eingeschraubt, deren Schraubenkopf 4 als Sechskant ausgebildet ist. Die Schraube hält ein Befestigungsstück 5 an der Gebäudeaußenwand 1, das aus einem endlosen Profilstrang durch ablängen hergestellt ist. Das Befestigungsstück 5 weist ein Bodenteil 6 und zwei etwa im Winkel von 45° von der Gebäudeaußenwand 1 abstehende Schenkel 7 auf. Der Bodenteil 6 liegt an der Gebäudeaußenwand 1 flächig an und weist zwei Leisten 8 auf, die den Kopf 4 der Schraube 3 gegen ein Verdrehen sichern.In Fig. 1, part of an outer wall 1 of the building is indicated, in which a dowel 2 is inserted. A screw 3 is screwed into the dowel, the screw head 4 of which is designed as a hexagon. The screw holds a fastening piece 5 on the outer wall 1 of the building, which is made by cutting to length from an endless profile strand. The fastening piece 5 has a base part 6 and two legs 7 projecting approximately at an angle of 45 ° from the outer wall 1 of the building. The base part 6 lies flat against the outer wall 1 of the building and has two strips 8 which secure the head 4 of the screw 3 against rotation.

Die beiden Schenkel 7 des Befestigungsstücks 5 sind mit zwei in Längsrichtung der Schenkel 7 erstreckenden Schlitzen 9 versehen, in die Vorsprünge 10 eines flächigen Verbindungsstücks 11 eingreifen. Die Vorsprünge 10 sind durch Ausnehmungen 12 hergestellt, in die die freien Enden der Schenkel 7 eingreifen können. Sowohl die Vorsprünge 10 als auch die Ausnehmungen 12 weisen eine Schräge von etwa 45° auf. Die Vorsprünge 10 können daher zur Montage des flächigen Verbindungsteils 11 an dem Befestigungsstück 5 gegen die freien Enden der Schenkel 7 gedrückt werden, wodurch sie mit der Schräge an der Innenseite der Schenkel 7 anliegen. Durch Ausübung eines Druckes in Richtung auf die Gebäudewand 1 werden die Schenkel 7 gespreizt und die Vorsprünge 10 schnappen in die Schlitze 9 der Schenkel 7 ein. Die Schräge der Ausnehmungen 12 liegt nun parallel zu den Schenkeln 7 des Befestigungsstücks 5.The two legs 7 of the fastening piece 5 are provided with two slots 9 which extend in the longitudinal direction of the legs 7 and into which projections 10 of a flat connecting piece 11 engage. The projections 10 are produced by recesses 12 into which the free ends of the legs 7 can engage. Both the projections 10 and the recesses 12 have a slope of approximately 45 °. The projections 10 can therefore be pressed against the free ends of the legs 7 for mounting the flat connecting part 11 on the fastening piece 5, as a result of which they are inclined on the inside the leg 7 rest. By applying pressure in the direction of the building wall 1, the legs 7 are spread apart and the projections 10 snap into the slots 9 of the legs 7. The slope of the recesses 12 is now parallel to the legs 7 of the fastening piece 5.

Das flächige Verbindungsstück 11 ist mit zwei Bohrungen 13 versehen, durch die die Befestigung des flächigen Verbindungsstücks 11 an einer flächig an dem Verbindungsteil 11 anliegenden Befestigungsleiste eines Fassadenelements erfolgt. Unterhalb der Bohrungen 13 ist eine Klemmfeder 14 freigestanzt und gebogen, die einen Zwischenraum 15 mit dem flächigen Verbindungsteil 11 bildet, in den eine Befestigungsleiste 16 des Fassadenelements eingeschoben werden kann. Dadurch ist das Fassadenelement vorläufig festgelegt und kann ausgerichtet werden. Nach der Ausrichtung erfolgt dann die endgültige Befestigung mittels üblicher Befestigungsmittel durch die Bohrungen 13 hindurch. (vgl. Fig. 2)The flat connecting piece 11 is provided with two bores 13, through which the flat connecting piece 11 is fastened to a fastening strip of a facade element lying flat against the connecting part 11. Below the bores 13, a clamping spring 14 is punched out and bent, which forms an intermediate space 15 with the flat connecting part 11, into which a fastening strip 16 of the facade element can be inserted. As a result, the facade element is provisionally fixed and can be aligned. After the alignment, the final fastening is then carried out through the bores 13 by means of conventional fastening means. (see Fig. 2)

Die Bohrungen 13 müssen bei der erfindungsgemäßen Befestigungsvorrichtung nicht mehr, wie dies bei den bekannten Befestigungsvorrichtungen der Fall war, als Langlöcher ausgebildet sein, da eine eventuelle Längenänderung der Fassadenplatten in der Verbindung zwischen dem flächigen Verbindungsstück 11 und dem Befestigungsstück 5 aufgefangen wird, so daß eine praktisch reibungsfreie Verschiebung der Fassadenplatten möglich ist.The holes 13 no longer have to be designed as elongated holes in the fastening device according to the invention, as was the case with the known fastening devices, since a possible change in length of the facade panels is caught in the connection between the flat connecting piece 11 and the fastening piece 5, so that a practically frictionless displacement of the facade panels is possible.

Die erfindungsgemäße Befestigungsvorrichtung erlaubt weiterhin eine einfache Lagerhalterung, da die Befestigungsstücke 5 gut ineinander schachtelbar und die flächigen Verbindungsteile 11 gut auf kleinstem Raum stapelbar sind. Sie lassen sich daher auch in großer Stückzahl in relativ kleinen Verpackungen versenden.The fastening device according to the invention also allows simple bearing support, since the fastening pieces 5 can be nested well into one another and the flat connecting parts 11 can be stacked well in the smallest space. They can therefore also be sent in large quantities in relatively small packaging.
