In einem Bohrloch einer Wand verankerbares BefestigungselementFastening element which can be anchored in a borehole in a wall

(Zusatz zu Patent . . . Patentanmeldung P 17 SO 829.1 )(Addition to patent... Patent application P 17 SO 829.1)

Das Hauptpatent betrifft ein in einem Bohrloch einer Wand od.dgl. 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 Spreizhülse aufschiebbar ist, die einen sich in gleicher Richtung verjüngenden Innenkonus besitzt. Aufgabe des Hauptpatentes ist es, ein Befestigungselement zu schaffen, das in einem Bohrloch einer Wand sicher und wirksam verankert werden kann. Dazu ist es erforderlich, daß schon bei Beginn der Verankerung die Spreizhülse möglichst stark aufgespreizt wird, um eine gute Verankerung gegen ihr Mitdrehen zu erzielen. Nach dem Hauptpatent wird zur Lösung dieser Aufgabe vorgeschlagen, daß der Konus ein Gewinde trägt und die Spreizhülse einen sich in Bezug auf den Konus des Befestigungselementes in gleicher Richtung verjüngenden Innenkonus aufweist, dessen Grad der Verjüngung ein anderer ist, als beim Konus des Befestigungeelementes. Durch den unterschiedlichen Grad der Verjüngung erfaßt das Gewinde des Konus des Befestigungselementes die Hülse zunäohet nur an einerThe main patent relates to a wall or the like in a borehole. anchorable by means of an expansion sleeve bolt-shaped fastening element, which in the area of its protruding into the borehole part with a towards the end of the fastening element tapering cone is provided on which the expansion sleeve can be pushed, which has an inner cone tapering in the same direction. Task of the main patent is it is to provide a fastener that can be safely and effectively anchored in a borehole in a wall. For this it is necessary that the expansion sleeve is as strong as possible at the beginning of the anchoring is splayed to make a good anchorage against her To achieve co-rotation. According to the main patent it is proposed to solve this problem that the cone is a Has a thread and the expansion sleeve is in relation to the cone of the fastening element in the same Direction tapering inner cone, the degree of tapering is different than the cone of the fastening element. By the different degree the taper engages the thread of the cone of the fastening element, the sleeve only at one

Stelle, an der die Hülse sofort aufgespreizt wird. Die Reibung zwischen Befestigungselement und HUlse ist daher zunächst kleiner als zwischen Hülse und Bohrung, so daß ein Mitdrehen der Spreizhülse vermieden ist. Place where the sleeve is immediately spread open. The friction between the fastening element and the sleeve is therefore initially less than between the sleeve and the bore, so that the expansion sleeve does not rotate at the same time .

Neben dieser Lösungsmöglichkeit schlägt nun die vorliegende Zusatzerfindung zur Lösung dieser Aufgabe vor, daß der Querschnitt des Innenkonus ie Bereich seines verjüngten Endes eine von der im übrigen Bereich vorhandenen Kreisform abweichende Form aufweist. Diese abweichende Form kann vorzugsweise rechteckig sein. Es ist aber auch möglich, diese Form durch längslaufende, kurze, über den Umfang verteilte Rippen zu erzielen. Jede andere Form, wie dreieckig oder oval ist möglich. Der Übergang von der Kreisform in die davon abweichende Form kann allmählich oder aber abrupt erfolgen. In addition to this possible solution , the present additional invention now proposes to solve this problem that the cross-section of the inner cone, ie the region of its tapered end, has a shape that deviates from the circular shape present in the remaining region . This different shape can preferably be rectangular . But it is also possible to achieve this shape by means of longitudinal , short ribs distributed over the circumference. Any other shape, such as triangular or oval, is possible. The transition from the circular shape to the shape deviating therefrom can take place gradually or abruptly.

Durch diese Formänderung im Bereich des sich' verjüngenden Endes des Konus erfaßt das Gewinde dee Konus des Befestigungselementes die Hülse ebenfalls zunächst nur an einer Stelle, nämlich im Bereich de's verjüngten Endes. Somit bleibt die Reibung zwischen Befestigungselement und Hülse wegen der kleinen Berührungefläche zunächst kleiner als zwischen Hülse und Bohrung. Ein Mitdrehen der Spreizhülse ist dadurch vermieden. Hach wenigen Umdrehungen erfolgt eine verhältnismäßig starke Spreizung der Spreizhülse, wodurch die Verankerung gegen Mitdrehen in zunehmendem Maße erhöht wird. Bei weiterem Eindrehen erfaßt dann das Befestigungselement mit seinem gesamten Gewinde die Spreizhülse und spreizt diese über ihre gesamte Länge auf.As a result of this change in shape in the area of the tapering end of the cone, the thread of the cone of the fastening element also initially only engages the sleeve at one point, namely in the area of the tapered end. Because of the small contact surface, the friction between the fastening element and the sleeve initially remains smaller than between the sleeve and the bore. A co-rotation of the expansion sleeve is avoided. After a few turns there is a relatively strong expansion of the expansion sleeve, as a result of which the anchoring against co- rotation is increased to an increasing degree. With further screwing in, the fastening element then grips the expansion sleeve with its entire thread and expands it over its entire length.

Bei einer Spreizhülse, die einen vorzugsweise über ihre ganze Länge gehenden Schlitz aufweist, hat es sich in In the case of an expansion sleeve, which preferably has a slot extending over its entire length , it is advantageous in

Ausgestaltung der Erfindung als zweckmäßig erwiesen, daß bei rechteckiger Form des Querschnitts im Bereich des verjüngenden Endes die Schmalseite des Rechteckes rechtwinklig zur Schlitzebene steht. Dadurch erfolgt rechtwinklig zur Schlitzebene die stärkste Materialverdrängung und damit die stärkste Spreizwirkung, die durch den Schlitz erleichtert ist.Embodiment of the invention proved to be useful that with a rectangular shape of the cross section in the area of the tapering end, the narrow side of the rectangle is at right angles to the slot plane. This takes place at right angles to the slot plane the strongest material displacement and thus the strongest expansion effect, the is facilitated by the slot.

Die Spreizhülse θ ist mit einem Innenkonus 9 versehen, der sich in gleichem Sinne verjüngt wie der Konus 5. Im Bereich des verjüngten Endes des Innenkonus 9 geht dieser von seinem sonst kreisförmigen Querschnitt in einen rechteckigen Querschnitt 16 über. Die Hülse weist einen über ihre ganze Länge sich erstreckenden Schlitz 17 auf.At its end, the fastening element 3 has a cone 5 which has a sawtooth-shaped thread 6 is provided.
