Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines Montagewinkels zum Befestigen von Fassadenelementen an einer Wand. Der mit dem erfindungsgemäßen Verfahren hergestellte Montagewinkel zum Befestigen von Fassadenelementen an einer Wand, weist einen ersten Schenkel, der an einer Außenwand zu befestigen ist, und einen zweiten Schenkel, an welchem eine Montageleiste für Fassadenelemente befestigt werden kann, auf, die in einem Winkel von etwa 90° abgewinkelt sind, wobei das freie Ende des zweiten Schenkels im Wesentlichen flach ist und Öffnungen für Schraub- oder Nietverbindungen aufweist. Ein derartiger Montagewinkel ist beispielsweise aus der AT 403 304 B und ein ähnlicher Montagewinkel ist beispielsweise aus der EP 1 388 620 A2 bekannt. Die Herstellung derartiger Montagewinkel ist aufwändig bzw. mit hohen Werkzeugkosten verbunden, da für Montagewinkel mit unterschiedlichen Schenkellängen jeweils separate Werkzeuge benötigt werden, um sowohl die Sicken als auch die Öffnungen für die Schraub- oder Nietverbindungen herzustellen.The invention relates to a method for producing a mounting bracket for fastening facade elements to a wall. The mounting bracket produced by the method according to the invention for fastening facade elements to a wall, has a first leg which is to be fastened to an outer wall, and a second leg, to which a mounting strip for facade elements can be attached, which at an angle of are angled approximately 90 °, wherein the free end of the second leg is substantially flat and has openings for screw or rivet connections. Such a mounting bracket is for example from the AT 403 304 B and a similar mounting angle is for example from the EP 1 388 620 A2 known. The production of such mounting bracket is complex or associated with high tooling costs, since for mounting angles with different leg lengths each separate tools are needed to produce both the beads and the openings for the screw or rivet.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Verfahren zum Herstellen von Montagewinkeln zur Verfügung zu stellen, mit dem Montagewinkel mit unterschiedlichen Schenkellängen einfach und kostengünstig hergestellt werden können.The invention is therefore based on the object to provide a method for producing mounting brackets available, can be easily and inexpensively manufactured with the mounting bracket with different leg lengths.

Gelöst wird diese Aufgabe mit einem Verfahren mit den Verfahrensschritten gemäß Anspruch 1. Alternativ kann diese Aufgabe auch mit einem Verfahren mit den Verfahrensschritten gemäß Anspruch 2 gelöst werden.This object is achieved by a method with the method steps according to claim 1. Alternatively, this object can also be achieved by a method with the method steps according to claim 2.

Bisher wurden Montagewinkel der gegenständlichen Art aus einem flachen Blech hergestellt, indem die Profilierung beziehungsweise die Sicken sowie die Öffnungen für die Schraub- oder Nietverbindungen in einem einzigen oder aufeinander folgenden Stanz- und Press- und/oder Tiefziehvorgängen hergestellt wurden, wobei für jede Schenkellänge eine eigene Stanz- und Press- und/oder Tiefziehform benötigt wurde.So far, mounting angles of the subject type were made from a flat sheet metal by the profiling or the beads and the openings for the screw or rivet joints were made in a single or sequential punching and pressing and / or deep drawing operations, wherein for each leg length own punching and pressing and / or thermoforming mold was needed.

Bei der Erfindung wird demgegenüber ein rollgeformtes Profil verwendet, welches bereits die für die Steifigkeit des Profils erforderliche Profilierung, z.B. in Form von einer oder mehreren in Längsrichtung des Profils verlaufenden Sicken mit dazwischen bzw. daneben liegenden flachen Bereichen, aufweist. Bei diesem rollgeformten Profil, welches sehr präzise und kostengünstig hergestellt werden kann, muss dann nur ein freies Ende flach gepresst werden, wobei in diesem Arbeitsvorgang bevorzugt auch gleich die erforderlichen Öffnungen hergestellt werden können. Da bei diesem Vorgang nur das Ende des Schenkels bearbeitet wird, muss auch nur dieses Ende im Bearbeitungswerkzeug aufgenommen werden, weshalb es belanglos ist, wie lange dieser Schenkel tatsächlich ist. Es können somit mit einem einzigen Werkzeug Montagewinkel mit unterschiedlichen Schenkellängen bearbeitet werden.In the invention, in contrast, a roll-formed profile is used, which already has the required for the stiffness of the profile profiling, for example in the form of one or more running in the longitudinal direction of the profile beads with intermediate or adjacent flat areas. In this rollformed profile, which is very precise and inexpensive can be made, then only one free end must be pressed flat, in this operation preferably also equal to the required openings can be made. Since only the end of the leg is machined in this process, only this end must be included in the machining tool, so it is irrelevant how long this leg actually is. It can thus be processed with a single tool mounting bracket with different leg lengths.

Das Abwinkeln des Profiles zum Herstellen der beiden Schenkel kann erfindungsgemäß vor oder nach dem Flachpressen des freien Endes des einen Schenkels durchgeführt werden.The bending of the profile for producing the two legs can be carried out according to the invention before or after the flat pressing of the free end of the one leg.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung unter Bezugnahme auf die Zeichnungen.Further features and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention with reference to the drawings.

Es zeigt Fig. 1 einen erfindungsgemäßen Montagewinkel in Seitenansicht, Fig. 2 den Montagewinkel in Draufsicht und Fig. 3 den Montagewinkel in Vorderansicht.It shows Fig. 1 a mounting bracket according to the invention in side view, Fig. 2 the mounting bracket in plan view and Fig. 3 the mounting bracket in front view.

In den Fig. 1 bis 3 ist ein erfindungsgemäßer Montagewinkel dargestellt, der wie an sich bekannt einen ersten Schenkel 1 und einen zweiten Schenkel 2 aufweist, die im Bereich einer Biegung 10 im Winkel von etwa 90° angeordnet sind. Mit dem ersten Schenkel 1 wird der Montagewinkel an einem festen Untergrund wie zum Beispiel einer Hausmauer angeschraubt, wofür er in seinem Mittelbereich zwei als Langlöcher ausgeführte Öffnungen 3 aufweist. An seinem zweiten Schenkel 2 werden Montageleisten befestigt, an welchen Fassadenelemente direkt oder indirekt befestigt werden. Der Montagewinkel kann, wie dies an sich aus dem Stand der Technik bekannt ist, eine ausgestanzte und aus der Schenkelebene ausgeformte Zunge 4 aufweisen, damit die Montageleisten zur Erleichterung der Befestigung zwischen der Zunge 4 und dem Schenkel 2 festgeklemmt werden können. Außerdem weist der zweite Schenkel 2, wie dies ebenfalls an sich aus dem Stand der Technik bekannt ist, ein abgeflachtes freies Ende 5 auf, in welchem sich z.B. paarweise Öffnungen 6 und 7 befinden, durch welche der Schenkel 2 mit den Montageleisten verschraubt oder vernietet werden kann. Im dargestellten Ausführungsbeispiel sind die beiden Öffnungen 6 als Rundlöcher und die Öffnungen 7 als Langlöcher ausgeführt.In the Fig. 1 to 3 an inventive mounting bracket is shown, which as known per se has a first leg 1 and a second leg 2, which are arranged in the region of a bend 10 at an angle of about 90 °. With the first leg 1 of the mounting bracket is screwed to a solid surface such as a house wall, for which he has in its central region designed as two slots 3 openings. At its second leg 2 mounting strips are attached to which facade elements are attached directly or indirectly. The mounting bracket can, as is well known in the art, have a punched out and formed from the thigh plane tongue 4, so that the mounting rails between the tongue 4 and the leg 2 can be clamped to facilitate the attachment. In addition, the second leg 2, as is also known from the prior art, a flattened free end 5, in which, for example, pairs of openings 6 and 7 are, through which the legs 2 are screwed or riveted to the mounting rails can. In the illustrated embodiment, the two openings 6 are designed as round holes and the openings 7 as slots.

Im Bereich der Biegung 10 sind am zweiten Schenkel 2 in dessen flachem Mittelbereich 9 eine oder mehrere vorzugsweise zueinander versetzte Öffnungen 11 angebracht. Durch diese Öffnungen 11 wird der Wärmefluss durch den zweiten Schenkel 2 behindert. Außerdem dienen diese Öffnungen 11 zur Gewichtsreduktion des Montagewinkels, ohne dessen Biegesteifigkeit nennenswert nachteilig zu beeinflussen.In the region of the bend 10, one or more preferably offset openings 11 are attached to the second leg 2 in its flat central region 9. Through these openings 11, the heat flow is hindered by the second leg 2. In addition, these openings 11 are used to reduce the weight of the mounting bracket, without affecting the bending stiffness significantly disadvantageous.

Im dargestellten Ausführungsbeispiel weist das Profil, aus dem der Montagewinkel hergestellt ist, im Randbereich zwei Sicken 8, also zwei sich über den flachen Mittelbereich 9 erhebende, etwa U-förmige Profilierungen, auf, welche dem Montagewinkel die nötige Biegesteifigkeit verleihen. Es versteht sich, dass der erfindungsgemäße Montagewinkel auch aus anderen Profilformen hergestellt werden kann, welche beispielsweise auch nur eine oder mehr als zwei Sicken 8 oder anders geformte Profilierungen aufweisen können. Außerdem können seitlich außerhalb der Sicken 8 auch noch flache Bereiche angeordnet sein.In the illustrated embodiment, the profile from which the mounting bracket is made, in the edge region two beads 8, so two over the flat central region 9 uplifting, approximately U-shaped profiles, which give the mounting bracket the necessary bending stiffness. It is understood that the mounting bracket according to the invention can also be made of other profile shapes, which may have, for example, only one or more than two beads 8 or other shaped profilings. In addition, laterally outside the beads 8 also flat areas may be arranged.

Hergestellt wird der Montagewinkel nach dem erfindungsgemäßen Verfahren aus einem rollgeformten Profil, welches zunächst nur ein gerader, lang gestreckter Profilstab mit einer Profilform ist, welches im dargestellten Ausführungsbeispiel der Profilform des ersten Schenkels 1 entspricht. Von diesem Profilstab werden dann Profilstücke mit einer Länge abgetrennt, welche im Wesentlichen der Summe der Längen der beiden Schenkel 1 und 2 entspricht.The mounting bracket is produced by the method according to the invention from a roll-formed profile, which is initially only a straight, elongated profile bar with a profile shape, which corresponds to the profile shape of the first leg 1 in the illustrated embodiment. From this profile bar profile pieces are then separated with a length which substantially corresponds to the sum of the lengths of the two legs 1 and 2.

Die nachfolgenden Bearbeitungsschritte können hinsichtlich ihrer Reihenfolge auch anders ausgeführt werden.The subsequent processing steps can be carried out differently in terms of their order.

Zunächst wird das Ende 5 des zweiten Schenkels 2 in eine Stanz- und Pressform gesteckt und flach in eine Form gepresst, wie sie in den Fig. 1 und 2 zu sehen ist. Da das ursprüngliche Profil die Sicken 8 aufweist, welche in der Stanz- und Pressform flach gepresst werden, verbreitert sich das Ende 5 im Vergleich zum dahinter liegenden, unverformten Schenkel 2. Bei diesem Vorgang werden bevorzugt auch die Öffnungen 6, 7 und die Zunge 4 ausgestanzt bzw. ausgeformt.First, the end 5 of the second leg 2 is inserted into a punching and pressing mold and pressed flat into a mold, as in the Fig. 1 and 2 you can see. Since the original profile has the beads 8, which are pressed flat in the punching and pressing, the end 5 widened in comparison to the underlying, undeformed leg 2. In this process, the openings 6, 7 and the tongue 4 are preferred stamped or formed.

Anschließend können die Öffnungen 11, die im flachen Mittelbereich 9 vor der Biegung 10 liegen, und in einem weiteren Arbeitsschritt die Langlöcher 3 im ersten Schenkel 1 hergestellt werden. Schließlich wird das Profil an der Biegung 10 etwa im rechten Winkel abgebogen, so dass die beiden Schenkel 1 und 2 entstehen.Subsequently, the openings 11, which lie in the flat central region 9 in front of the bend 10, and in a further step, the slots 3 in the first leg 1 are produced. Finally, the profile is bent at the bend 10 approximately at right angles, so that the two legs 1 and 2 arise.
