Description

In einem Bohrloch einer Wand verankerbares Befestigungselement (Zusatz zu Patent . . . Patentanmeldung P 17 50 829.1) Das Hauptpatent betrifft ein in einem Bohrloch einer Wand oder dergl. mittels einer Spreizhülse verankerbares bolzenförmiges Befestigungselement, das im Bereich seines in das Bohrloch ragenden Teiles mit einem sich zum Ende des Befestigungselementes hin verjüngenden Konus versehen ist, auf den die SpreizhUlse aufziehbar ist. Dabei trägt der Konus ein Gewinde und die Spreizhülse weist einen sich in Bezug auf den Konus des Befestigungselementes in gleicher Richtung sich verjüngenden Innenkonus auf. Fastening element that can be anchored in a borehole in a wall (suffix to patent. . . Patent application P 17 50 829.1) The main patent concerns one in one Borehole in a wall or the like. Bolt-shaped anchored by means of an expansion sleeve Fastening element, which in the area of its protruding into the borehole part with a is provided towards the end of the fastening element tapering cone which the expansion sleeve can be pulled up. The cone has a thread and the expansion sleeve has one in relation to the cone of the fastening element in the same direction tapered inner cone.

Der Erfindung liegt die Aufgabe zugrunde, die Spreizhülse so auszugestalten, daß ein unbeabsichtigtes Mitdrehen während des Einschraubens des Befestigungselementes unterbunden ist.The invention is based on the object of designing the expansion sleeve in such a way that that unintentional turning while screwing in the fastener is prevented.

In weiterer Ausgestaltung der Erfindung nach dem Hauptpatent wird dies dadurch erreicht, daß die Spreizhülse an ihrem Außenumfang mit elastisch nachgiebigen oder mit festen, aber verformbaren Sperrmitteln gegen Mitdrehen versehen ist.In a further embodiment of the invention according to the main patent this is achieved in that the Expansion sleeve on its outer circumference with resilient or with firm but deformable locking means against Rotating is provided.

Die Sperrmittel dienen als Dreh- und Haltesicherung in weichem und hartem Werkstoff, der das Bohrloch umgibt. Die nachgiebigen Sperrmittel werden vorzugsweise dann verwendet, wenn das Befestigungselement nach der Durchsteckmontage eingesetzt werden soll. Die elastischen Sperrmittel federn beim Durchschieben durch die Bohrung im zu befestigenden Bauteil und beim Einschieben der Hülse in eine im Mauerwerk vorbereitete Bohrung zurück, sie können aber jederzeit in entsprechende Unebenheiten der Bohrlochwand eingreifen und so ein Mitdrehen der Hülse und auch ein Herausfallen aus vertikalen Bohrlöchern verhindern. Bei Befestigungen, die nicht nach der Durchsteckmontage vorgenommen werden, eignen sich die festen, aber verformbaren Sperrmittel gut. Beim Einschieben der Hülse in ein vorbereitetes Bohrloch werden die Sperrmittel verformt und bewirken durch ihren Verformungswiderstand ein Verkeilen der Hülse im Bohrloch. Damit ist auch bei solchen Sperrmitteln eine Drehsicherung geschaffen.The locking means serve as a rotation and holding lock in soft and hard material surrounding the borehole. The compliant locking means are preferred used when the fastener is inserted after push-through installation shall be. The elastic locking means spring when it is pushed through the bore in the component to be fastened and when inserting the sleeve into one in the masonry prepared hole back, but you can always in corresponding unevenness engage in the wall of the borehole, causing the sleeve to rotate and fall out prevent from vertical drill holes. For fixings that are not made after push-through installation are made, the solid but deformable locking means are well suited. At the Pushing the sleeve into a prepared borehole deforms the locking means and cause the sleeve to wedge in the borehole due to its resistance to deformation. A rotation lock is thus created even with such locking means.

In zweckmäßiger Ausgestaltung der Erfindung können die Sperrmittel Zungen sein, die im Bereich des dem Bohrlochgrund zugewendeten Endes der Spreizhtllse angesetzt sind und sich zum anderen Ende hin in Hlsenlängsrichtung.in einer radialen Ebene vom Hulsenaußenumfang weg erstrecken.In an expedient embodiment of the invention, the locking means Be tongues in the area of the end of the expansion sleeve facing the bottom of the borehole are attached and extend towards the other end in the longitudinal direction of the sleeve in a radial direction Extend the plane away from the outer circumference of the sleeve.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Am Außenumfang der Hülse 8 sind diametral gegen-Uberliegend zwei Ausnehmungen 18 angeordnet. An der dem Ende 19 der Hülse 8 zugewendeten Begrenzungskante 20 dieser Ausnehmungen 18 sind Sperrzungen 21 angeformt, die sich von dieser Stelle aus in Längsrichtung der Spreizhülse in einer radialen Ebene vol Dübelaußenumfang weg nach außen erstrecken.On the outer circumference of the sleeve 8 there are two diametrically opposite recesses 18 arranged. At the end 19 of the sleeve 8 facing boundary edge 20 of this Recesses 18 are molded locking tongues 21 that extend from this point in Longitudinal direction of the expansion sleeve in a radial plane vol dowel outer circumference away extend outside.

Statt zwei solcher Sperrzungen können auch mehrere angeordnet werden.Instead of two such locking tongues, several can be arranged.
