Abstract
Description
Die Erfindung betrifft ein Befestigungselement, bestehend aus einem in einem Mauerwerk mittels Schraube, Nagel oder dgl verankerbaren Dübel, der einen die Mauerwerksoberfläche überragenden verlängerten Hals aufweist, an dessen Ende eine Halterung für die Befestigung eines als Putz- oder Fassadenträger dienenden Drahtgitters in einem Abstand zum Mauerwerk angeordnet ist.The invention relates to a fastening element consisting of a dowel which can be anchored in a masonry by means of a screw, nail or the like and which has an elongated neck projecting beyond the masonry surface, at the end of which a holder for fastening a wire mesh serving as plaster or facade support at a distance from Masonry is arranged.
Für die Anbringung von Fassaden und Verputze im Abstand zum Stützmauerwerk können als Träger Drahtgitter-Matten verwendet werden, die in einem Abstand . zu der Außenfläche des Mauerwerks zu befestigen sind. Das Drahtgitter muß so befestigt werden, daß es in der Lage ist, das Gewicht des Putzes bzw: der Fassade einerseits und die auf die Außenhaut wirkenden Winddruck-" und Sogkräfte andererseits aufzunehmen.For the installation of facades and plasters at a distance from the supporting masonry, wire mesh mats can be used as supports, which are at a distance. to be attached to the outer surface of the masonry. The wire mesh must be fastened so that it is able to absorb the weight of the plaster or: the facade on the one hand and the wind pressure and suction forces acting on the outer skin on the other.
Es ist ein Spreizdübel zur Abstandsbefestigung des Drahtgitters bekannt, bei dem die Abstandshalterung durch einen radial abstehenden, quer zur Längsachse des Dübels eine der Drahtdicke entsprechende Einschlitzung aufweisenden Nocken gebildet ist. Zur Abstandsbefestigung des Drahtgitters mit diesem Dübel werden zunächst entsprechend der erforderlichen Verteilung der Befestigungselemente die Bohrungen hergestellt, wobei jeweils in der Mitte zwischen zwei vertikal verlaufenden Drähten und unterhalb des einzuhängenden horizontalen Drahtes gebohrt wird. Der Dübel wird dann mit horizontal gerichtetem Nocken in das Bohrloch soweit eingeschoben, bis die Einschlitzung unterhalb des horizontal verlaufenden Drahtes liegt. Durch Drehen des Dübels im Bohrloch um 90 Grad schwenkt der am Dübelhals angeordnete Nocken in den horizontal liegenden Draht ein. Damit ist der Draht in Axialrichtung des Dübels fest arretiert. Durch Eintreiben einer Schraube, Nagel oder dgl. in den Dübel wird dieser im Mauerwerk fest verankert und gleichzeitig die Stellung des Nockens fixiert. Eine Änderung des Abstandes zwischen Drahtgitter-und Wand ist während der Montage in einfacher Weise dadurch möglich, daß vor Aufspreizen des Dübels dieser im Bohrloch entsprechend verschoben.wird.There is known an expansion dowel for fastening the spacer of the wire mesh, in which the spacer is formed by a radially protruding cam having a slot corresponding to the wire thickness and transverse to the longitudinal axis of the dowel. To fix the spacing of the wire mesh with this dowel, the holes are first made in accordance with the required distribution of the fastening elements, drilling in the middle between two vertically running wires and below the horizontal wire to be hooked in. The dowel is then pushed into the borehole with the cam aligned horizontally until the slot lies below the horizontally running wire. By turning the dowel in the drill hole by 90 degrees, the cam arranged on the dowel neck swings into the horizontally lying wire. The wire is thus firmly locked in the axial direction of the dowel. By driving a screw, nail or the like into the dowel, it is firmly anchored in the masonry and at the same time the position of the cam is fixed. A change in the distance between the wire mesh and the wall is easily possible during assembly by moving the dowel accordingly in the borehole before it is spread.
Da der Spreizdübel und die Halterung aus Kunststoff bestehen, besteht bei diesem Dübel die Gefahr, daß-bei einem Brand die Befestigung des Drahtgitters und damit die Fassade sich vorzeitig löst.Since the expansion dowel and the bracket are made of plastic, there is a risk with this dowel that in the event of a fire, the fastening of the wire mesh and thus the facade will come off prematurely.
Der Erfindung liegt daher die Aufgabe zugrunde, die bekannte Halterung in der Weise zu verbessern, daß der zuvor geschilderte Nachteil nicht eintreten kann.The invention is therefore based on the object of improving the known holder in such a way that the disadvantage described above cannot occur.
Erfindungsgemäß wird dies dadurch erreicht, daß über den Schaft der Schraube, Nagel oder dgl. eine aus nicht brennbarem Material bestehende, mit einer Bohrung versehende Klammer gestülpt ist, die wenigstens einen über den von der Halterung erfaßten Draht des Drahtgitters einhängbaren Haken aufweist.According to the invention this is achieved in that a non-combustible material with a hole is placed over the shaft of the screw, nail or the like.
Durch die aus nicht brennbarem Material beispielsweise einem Metallblech bestehende und über den Schaft der Schraube, Nagel oder dgl. gestülpte Klammer ergibt sich eine unmittelbare Verbindung des Drahtgitters mit der Schraube. Brennt bzw. schmilzt bei einem Brandfall die Kunststoffhalterung des Dübels ab, wird durch die Klammer verhindert, daß das Drahtgitter über den Schraubenkopf hinweg abgleiten kann. Somit wird das Drahtgitter von den das Mauerwerk überragenden Schrauben zumindest so lange gehalten, daß keine Gefährdung durch herabfallende Fassadenteile mehr eintreten kann.The clip, which consists of a non-combustible material, for example a metal sheet, and is placed over the shaft of the screw, nail or the like, results in a direct connection of the wire mesh with the screw. If the plastic holder of the dowel burns or melts in the event of a fire, the clamp prevents the wire mesh from sliding over the screw head. Thus, the wire mesh is held by the screws projecting beyond the masonry at least so long that there is no longer any danger from falling facade parts.
In einer weiteren Ausgestaltung der Erfindung kann die Bohrung-der Klammer mit einer als trichterförmige Prägung ausgebildeten, dem Kopf der Schraube, Nagel.oder dgl. angepaßten Senkung versehen sein. Durch diese Ausbildung ergibt sich zum einen eine Formversteifung der Klammer und zum anderen eine in die Dübelsenkung passende Prägung, die eine bündige Montage der Schraube trotz der zwischen Schraubenkopf und Dübelstirnseite angeordneten Klammer zuläßt.In a further embodiment of the invention, the bore of the clamp can be provided with a depression designed as a funnel-shaped embossment and adapted to the head of the screw, nail or the like. This design results in a stiffening of the clip on the one hand and, on the other hand, an embossing which fits into the dowel recess and which permits flush mounting of the screw despite the clip arranged between the screw head and the end face of the dowel.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.
- Es zeigen: Figur 1 das Befestigungselement mit Drahtgitter und eingehängter Klammer
Figur 2 die Aufhängung des Drahtgitters an einem mit Wärmedämmplatten versehenen Mauerwerk.
- FIG. 1 shows the fastening element with a wire mesh and a suspended bracket
- Figure 2 shows the suspension of the wire mesh on a masonry provided with thermal insulation panels.
Zur Verankerung des Dübels 1 wird durch die Wärmedämmplatten 2 hindurch in das Mauerwerk 3 ein Bohrloch 4 hergestellt, dessen Lage so gewählt ist, daß die Oberkante des Bohrloches 4-mit der Unterkante des horizontal verlaufenden Drahtes fluchtet und etwa in der Mitte zweier vertikal verlaufender Drähte angeordnet ist. Danach wird der Dübel 1 bei horizontaler Stellung des Nockens 5 soweit eingeschoben, bis die Stirnseite 6 des vom Nocken 5 ausgehenden und in Längsrichtung des Dübels 1-Verlaufenden Steges 7 an der.Außenfläche der Wärmedämmplatte 2 anstößt. Durch Drehen des Dübels 1 im Bohrloch 4 um 90 Grad kommt der horizontal verlaufende Draht des Drahtgitters 8 in der Einschlitzung 9 zum Eingriff. Durch die der Drahtdicke angepaßte Weite der Einschlitzung 9 ergibt sich eine feste Arretierung des Drahtgitters 8 in Achsrichtung des Dübels 1. Danach wird die aus einem nicht brennbarem Material beispielsweise aus Aluminium, rostfreiem Stahl oder dgl. bestehende Klammer 10 über den horizontal verlaufenden Draht und der Halterung des Dübels eingehängt und so verschoben, daß die Bohrung 11 der Klammer 10 mit der Bohrung 12 des Dübels fluchtet. Durch die als trichterförmige Prägung 13 ausgebildete Senkung ergibt sich in der Senkung des Dübels bereits eine Vorfixierung. Nach Einstellung des Abstandes des. Drahtgitters 8 vom Mauerwerk 3 durch Verschieben des Dübels in Achsrichtung wird der Dübel 1 durch Eindrehen der Schraube 14 fest im Mauerwerk verankert. Gleichzeitig wird damit die Klammer 10 durch den Schaft der Schraube 14 festgehalten. Damit entsteht eine Verbindung zwischen Schraube 14 und Drahtgitter 8, die beim Abschmelzen der aus Kunststoff bestehenden Halterung des Dübels ein Abgleiten des Drahtgitters 8 über den Schraubenkopf 15 verhindert.To anchor the dowel 1, a borehole 4 is made through the
Die über den Außenputz bzw. der Fassade auf das Drahtgitter 8 wirkenden Druck- und Sogkräfte werden über den Nocken 5 von dem Dübel 1 aufgenommen. Zum leichteren Verdrehen des Dübels 1 ist an dessen Stirnseite ein Schlitz 16 vorgesehen, an dem ein Drehwerkzeug, beispielsweise ein Schraubendreher ansetzbar ist.The pressure and suction forces acting on the wire mesh 8 via the external plaster or the facade are absorbed by the dowel 1 via the cams 5. For easier twisting of the dowel 1, a
