Abstract
Description
Die Erfindung betrifft eine Befestigungsvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a fastening device according to the Preamble of claim 1.
Eine
solche Befestigungsvorrichtung ist aus der
Ein Nachteil liegt darin, dass beim Herausziehen der Befestigungsvorrichtung die Wand des Bohrlochs abgeschliffen wird, so dass die Befestigungsvorrichtung das Bauelement nicht mehr halten kann, selbst wenn sie daraufhin schlagartig entlastet wird, d. h., wenn die Überlastung nur kurzfristig war.One Disadvantage is that when pulling out the fastening device the wall of the borehole is ground down so that the fastening device the component can no longer hold, even if they then suddenly relieved, d. h. when the overload was only short term.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Befestigungsvorrichtung zu schaffen, die aufgrund einer kurzfristigen Überlastung nicht dauerhaft versagt.Of the present invention is based on the object, a fastening device to create that due to a short-term overload not permanently failed.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.These The object is achieved by the features of claim 1.
Die Erfindung betrifft eine Befestigungsvorrichtung, wobei ein zweites Klemmelement vorgesehen ist, und wobei das erste Klemmelement und das zweite Klemmelement durch eine Verschiebung in Bezug auf den Spreizabschnitt des Befestigungselements relativ zueinander aufspreizbar sind, so dass das erste Klemmelement und das zweite Klemmelement gegen eine Wand eines Bohrlochs gedrückt werden können und das Befestigungselement zwischen den beiden Klemmelementen eingeklemmt werden kann. Das Befestigungselement selbst wird dabei nicht gegen die Wand des Bohrlochs gedrückt. Wenn die Befestigungsvorrichtung überlastet wird, wird das Befestigungselement entlang der beiden Klemmelemente aus dem Bohrloch gezogen. Beim Herausziehen aus dem Bohrloch verformt das Befestigungselement die beiden Klemmelemente fortwährend plastisch. Die Bohrlochwand wird nicht abgeschliffen. Eine Verschlechterung des Kontakts zwischen der Befestigungsvorrichtung und der Bohrlochwand erfolgt daher nicht. Ist die Überbelastung nur kurzfristig, stoppt die Bewegung des Befestigungselements, bevor es vollständig aus dem Bohrloch gezogen wurde.The The invention relates to a fastening device, wherein a second Clamping element is provided, and wherein the first clamping element and the second clamping element by a displacement with respect to the Spreading the fastener relative to each other spreadable are, so that the first clamping element and the second clamping element can be pressed against a wall of a borehole and the fastener between the two clamping elements are clamped can. The fastener itself is not against the Wall of the borehole pressed. When the attachment device overloads is, the fastener along the two clamping elements pulled out of the hole. When pulled out of the borehole deformed the fastener the two clamping elements continuously plastic. The borehole wall is not abraded. A deterioration the contact between the fixture and the borehole wall does not take place. If the overload is short-term, stops the movement of the fastener before it completely was pulled out of the hole.
In einer bevorzugten Ausführungsform weist das Befestigungselement einen U-förmigen Abschnitt mit zwei parallelen Befestigungsschenkeln und einem gebogenen Mittelteil auf, und das gebogene Mittelteil ist als Spreizabschnitt ausgebildet. Das gebogene Mittelteil ist das vordere Ende, welches zuerst in das Bohrloch gesteckt wird. Somit legt das Spreizelement bei einer Überbelastung einen möglichst langen Weg entlang der beiden Klemmelemente zurück. Die Befestigungsvorrichtung kann dementsprechend einer möglichst großen Überlastung widerstehen.In a preferred embodiment, the fastening element a U-shaped section with two parallel mounting legs and a bent middle part, and the curved middle part is formed as a spreading. The curved middle part is that front end, which is first inserted into the hole. Consequently sets the expansion element in an overload as possible long way back along the two clamping elements. The Fastening device can accordingly one of possible withstand major overload.
In einer Weiterbildung der bevorzugten Ausführungsform weist das Befestigungselement zwei gegenüberliegende nach außen gebogene Endabschnitte auf. Durch das Umbiegen der freien Enden des Befestigungselements kann auf einfache Weise eine wirkungsvolle Befestigungsvorrichtung geschaffen werden.In a development of the preferred embodiment has the fastener two opposite outward curved end sections on. By bending the free ends The fastener can be an effective way to easily Fastening device are created.
In einer weiteren bevorzugten Ausführungsform besteht das Befestigungselement aus einer gebogenen Metallstange. Geeignete Metallstangen sind leicht verfügbar und somit kostengünstig. Die Herstellung durch Biegen erfordert keinen hohen Zeitaufwand und lässt sich vollautomatisch mit hohem Durchsatz ausführen.In Another preferred embodiment is the Fastening element of a bent metal rod. suitable Metal bars are readily available and therefore inexpensive. The production by bending does not require a lot of time and can be fully automated with high throughput.
In noch einer weiteren bevorzugten Ausführungsform bilden die beiden Klemmelemente eine Klemmeinrichtung. Die beiden Klemmelemente sind zudem einstückig ausgebildet, durch ein Joch miteinander verbunden und parallel zueinander angeordnet, also insbesondere U-förmig. Die Handhabung einer einstückigen Klemmeinrichtung ist besonders einfach. Die parallele Anordnung der beiden Klemmelemente ist ideal an die Form eines Bohrlochs angepasst. Die Klemmelemente können fest über das Spreizelement geschoben werden, indem auf das gebogene Mittelteil mit einem Hammer geschlagen wird.In form yet another preferred embodiment the two clamping elements a clamping device. The two clamping elements are also integrally formed by a yoke with each other connected and arranged parallel to each other, ie in particular U-shaped. The handling of a one-piece clamping device is very easy. The parallel arrangement of the two clamping elements is ideally adapted to the shape of a borehole. The clamping elements can be pushed firmly over the spreader, by striking the curved middle section with a hammer.
In einer Weiterbildung der letztgenannten Ausführungsform haben das erste Klemmelement und das zweite Klemmelement jeweils ein freies Ende. Diese freien Enden des ersten Klemmelements und des zweiten Klemmelements sind jeweils abgeschrägt. Wenn die beiden freien Enden voraus in das Bohrloch eingeschoben werden, werden sie automatisch aufgespreizt, sobald sie auf den Spreizabschnitt stoßen.In a development of the latter embodiment have the first clamping element and the second clamping element respectively a free end. These free ends of the first clamping element and of the second clamping element are each bevelled. If the two free ends are pushed ahead into the borehole, they are automatically spread open as soon as they encounter the expansion section.
In einer Weiterbildung der letztgenannten Ausführungsform besteht die Klemmeinrichtung aus einer gebogenen Metallstange. Wie im Zusammenhang mit dem Befestigungselement erwähnt, sind geeignete Metallstangen leicht verfügbar und somit kostengünstig. Wie im Zusammenhang mit dem Befestigungselement ebenfalls erwähnt, erfordert die Herstellung durch Biegen keinen hohen Zeitaufwand und lässt sich vollautomatisch mit hohem Durchsatz ausführen. Somit lässt sich die gesamte Befestigungsvorrichtung preiswert in großen Stückzahlen herstellen.In a development of the latter embodiment the clamping device consists of a bent metal rod. As mentioned in connection with the fastener, are suitable metal bars readily available and therefore inexpensive. As also mentioned in connection with the fastener, The production by bending does not require much time and effort can be fully automated with high throughput. Thus, the entire fastening device can be inexpensively produce in large quantities.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher beschrieben.The Invention will be described below with reference to an embodiment described in more detail.
