Abstract
Description
Die Erfindung bezieht sich auf ein Befestigungselement zur Anbringung an einem Baukörper aus einem betonartigem Material mit einem Bohrerschaft, der an seinem einen Ende einen Antriebskopf und an seinem anderen Ende einen Bohrkopf aufweist, und der zwischen Antriebskopf und Bohrkopf eine Spannhülse trägt, die sich axial am Antriebskopf und am Bohrkopf abstützt und in ungespannter Lage so wenig den Durchmesser des Bohrkopfes übersteigt, dass sie sich nur geringfügig beim Eintreiben des Bohrschaftes in dem Baukörper zusammendrückt und in eingetriebener Lage an die Bohrungswandung anlegt. Zu dem betonartigen Material zählen alle im Bau üblichen Wand- und Deckenmaterialien aus mineralischen Werkstoffen.The invention relates to a fastener for attachment to a building of a concrete-like material with a drill shank having at one end a drive head and at its other end a drill head, and carries a clamping sleeve between the drive head and drill head, the axially on Actuator head and supported on the drill head and in the untensioned position so little exceeds the diameter of the drill head that it only slightly compresses when driving the drill shank in the building and rests in an in-situ position on the bore wall. The concrete-like material includes all common wall and ceiling materials made of mineral materials.
Ein derartiges Befestigungselement ist aus der
Der Erfindung liegt daher die Aufgabe zugrunde, ein Befestigungselement zur Anbringung an einem Baukörper aus einem betonartigen Material zu schaffen, das nach seiner Einbringung unter Mitnahme einer Spannhülse an dem Baukörper verbleiben kann und gegebenenfalls mit seinem Antriebskopf irgendwelche weiteren Bauteile, wie z. B. Verkleidungen oder Isolierungen, festzuhalten hat. Gelöst wird diese Aufgabe dadurch, dass der Bohrkopf auf seiner der Spannhülse zugewandten Seite mit einer kurzen kontinuierlichen Durchmessererweiterung in Richtung zum führenden Ende des Bohrkopfes versehen ist, die bei Einwirkung einer Rückziehkraft auf den Bohrschaft die Spannhülse derart aufspreizt, dass diese damit das Befestigungselement im Baukörper festhält.The invention is therefore an object of the invention to provide a fastener for attachment to a building of a concrete-like material that can remain after its introduction with entrainment of a clamping sleeve on the structure and optionally with its drive head any other components such. B. cladding or insulation, has to hold. This object is achieved in that the drill head is provided on its side facing the clamping sleeve with a short continuous diameter extension in the direction of the leading end of the drill head, which spreads the clamping sleeve upon application of a retraction force on the drill shank so that this so the fastener in the building holds.
Die Erfindung nutzt also die Spannhülse in einer gegenüber der bekannten Verwendung entgegengesetzten Weise aus, nämlich dadurch, dass die zunächst satt in das Bohrloch eingeführte Spannhülse bei Einwirkung einer Rückziehkraft durch die Durchmessererweiterung des Bohrkopf ausgedehnt und sich dabei so gegen die Wandung des Bohrlochs angepresst wird, dass damit ein Rückziehen des Bohrschaftes verhindert ist. Von Vorteil ist dabei besonders, dass mit zunehmender Rückziehkraft natürlich auch die Ausdehnung der Spannhülse aufgrund der Erweiterung des Bohrkopfes entsprechend ansteigt, so dass besonders stärker werdenden Rückziehkräften auch entsprechend stärker werdende Haltekräfte aufgrund des Anpressens der Spannhülse ausgelöst werden. Das Ergebnis ist, dass der Befestigungseffekt des erfindungsgemäßen Befestigungselementes besonders hoch ist und sich vor allem an die jeweils auf ihn auswirkenden Rückziehkräfte auch entsprechend anpasst.The invention thus uses the clamping sleeve in a manner opposite to the known use of the opposite way, namely the fact that the first fed richly into the borehole clamping sleeve extends under the action of a retracting force through the diameter extension of the drill head and is thereby pressed against the wall of the borehole, that thus retraction of the drill shank is prevented. Of particular advantage is that with increasing retraction force, of course, the expansion of the clamping sleeve due to the extension of the drill head increases accordingly, so that particularly strong retraction forces correspondingly stronger holding forces are triggered due to the pressing of the clamping sleeve. The result is that the attachment effect of the fastening element according to the invention is particularly high and, above all, also adapts accordingly to the respective retraction forces which act on it.
Eine besonders günstige Gestaltung der Durchmessererweiterung am Bohrkopf lässt sich dadurch herbeiführen, dass man diese als Konus ausbildet.A particularly favorable design of the diameter extension of the drill head can be brought about by forming it as a cone.
