Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Vorschub- und/oder Drehmomentübertragung auf Ankerstangen von Dübeln, insbesondere Verbunddübel oder dergleichen, mit einem Setzwerkzeug, das zur Aufnahme einer, am lastangriffseitigen Ende der Ankerstange konisch ausgebildete, Aussenkontur, eine konische Ausnehmung aufweist.The invention relates to a device for feed and / or torque transmission on anchor rods of dowels, in particular composite dowels or the like, with a setting tool, which has a conical recess for receiving a, conically formed on the load attack end of the anchor rod, outer contour.
Einrichtungen zur Vorschub- und/oder Drehmomentübertragung auf Ankerstangen ermöglichen dem Anwender ein leichtes und einfaches Setzen von Dübeln in einem mit einem Bohrloch versehenen Untergrund oder an einer mit einem Bohrloch versehenen Konstruktion. Insbesondere in Anwendung mit Verbunddübel kommt diese Einrichtung zum Einsatz, um die Ankerstange ins Bohrloch, das in diesem Beispiel ein Behältnis mit einer aushärtbaren Masse aufweist, zu setzen. Beim Setzvorgang wird die Ankerstange mittels der Einrichtung durch den von einem Verlegmittel erzeugten Vorschub und/oder Drehmoment drehend ins Bohrloch bewegt. Dabei wird das Behältnis mit der aushärtbaren Masse zerstört. Die austretende Masse vermischt sich mit Bohrklein und härtet aus. Bei mechanischen Dübeln bewirkt die Einrichtung durch die Übertragung beispielsweise ein Verspreizen des Dübels im Bohrloch.Means for feed and / or torque transfer to anchor rods allow the user to easily and easily set dowels in a downhole or downhole design. In particular, when used with composite dowel this device is used to set the anchor rod into the well, which in this example has a container with a curable composition. During the setting process, the anchor rod is moved by means of the device by the feed and / or torque generated by a laying means rotating into the borehole. The container is destroyed with the hardenable mass. The escaping mass mixes with cuttings and hardens. For mechanical anchors causes the device by the transfer, for example, a spreading of the anchor in the borehole.
Eine Einrichtung zur Vorschub- und/oder Drehmomentübertragung auf Ankerstangen von Dübeln, der genannten Art, ist beispielsweise aus der
Nachteilig an der bekannten Lösung ist, dass die Übertragung des Drehmomentes und des Vorschubes auf eine kleine Kontaktfläche zwischen der konischen Aussenkontur der Ankerstange und den Mitnehmerelementen im Innern der konischen Ausnehmung des Setzwerkzeuges begrenzt ist. Bei starker Belastung besteht somit in diesem Bereich die Gefahr eines Verschleisses der Ankerstange und des Setzwerkzeuges.A disadvantage of the known solution that the transmission of the torque and the feed is limited to a small contact surface between the conical outer contour of the anchor rod and the driver elements in the interior of the conical recess of the setting tool. Under heavy load there is thus the risk of wear of the anchor rod and the setting tool in this area.
Ferner ist bei der bekannten Lösung die Übertragung begrenzt, da nur eine kleine Kontaktfläche für die Reibungskraft, welche die Kraftübertragung sicherstellt, besteht. Dadurch besteht die Gefahr, dass bei der Übertragung von hohen Drehmomenten beispielsweise die Übertragung des Drehmomentes nur noch zum Teil oder gar nicht mehr gewährleistet ist, was beispielsweise zu einem nicht abgeschlossenen Setzvorgang führen kann.Furthermore, in the known solution, the transmission is limited, since only a small contact surface for the frictional force, which ensures the transmission exists. As a result, there is the danger that in the transmission of high torques, for example, the transmission of torque is only partially or not guaranteed, which may for example lead to an incomplete setting process.
Ausserdem sind Lösungen bekannt, wie z.B. aus der
Nachteilig an diesen bekannten Lösungen ist, dass die Gefahr des Verklemmens zwischen dem Setzwerkzeug und der Ankerstange besteht. Ausserdem wirkt sich eine solche Ausbildung am lastangriffseitigen Ende der Ankerstange negativ auf die Herstellungskosten derselben aus.A disadvantage of these known solutions is that there is a risk of jamming between the setting tool and the anchor rod. In addition, such training on the load attack end of the anchor rod has a negative effect on the manufacturing costs of the same.
Ferner ist die Handlichkeit der Einrichtung beschränkt, da ein genaues Positionieren des Setzwerkzeuges am lastangriffseitigen Ende der Ankerstange nötig ist, weil die Übertragung des Drehmomentes mittels eines Formschlusses geschieht.Furthermore, the handiness of the device is limited, since an accurate positioning of the setting tool on the load attack side end of the anchor rod is necessary because the transmission of the torque is done by means of a positive connection.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Vorschub-und/oder Drehmomentübertragung auf Ankerstangen von Dübeln, insbesondere Verbunddübel oder dergleichen, zu schaffen, die für hohe Drehmomente geeignet ist, ohne dass dabei die Gefahr eines Verklemmens zwischen Ankerstange und Setzwerkzeug besteht. Ferner soll sie für den Anwender handlich und ausserdem wirtschaftlich herstellbar sein.The present invention has for its object to provide a device for feed and / or torque transmission on anchor rods of dowels, especially composite dowels or the like, which is suitable for high torques, without causing the risk of jamming between anchor rod and setting tool. Furthermore, it should be handy for the user and also economically producible.
Die erfindungsgemässe Lösung geht davon aus, dass die konische Ausnehmung und die konische Aussenkontur einen Konuswinkel von 6° bis 16° aufweisen.The solution according to the invention assumes that the conical recess and the conical outer contour have a cone angle of 6 ° to 16 °.
Die konische Ausbildung der Ausnehmung und der Aussenkontur vergrössern gegenüber den bekannten Lösungen die Kontaktfläche zwischen Setzwerkzeug und Ankerstange und bewirken so eine vollständige Übertragung des Drehmomentes und des Vorschubes auch für hohe Werte. Insbesondere in der Anwendung mit Verbunddübel stellt die erfindungsgemässe Einrichtung ein vollständiges und handliches Setzen der Ankerstangen sicher. Ausserdem bleibt dem Anwender ein präzises Positionieren des Setzwerkzeuges erspart, da es sich um keinen Formschluss zur Übertragung des Drehmomentes handelt. Ferner ist durch die konische Ausbildung der Ausnehmung des Setzwerkzeuges und der Aussenkontur der Ankerstange die Verwendung desselben Setzwerkzeuges für Ankerstangen mit unterschiedlichen Durchmessern gewährleistet. Durch die einfache Ausgestaltung der Ankerstange ist eine wirtschaftliche Herstellung derselben möglich.The conical design of the recess and the outer contour increase compared to the known solutions, the contact surface between setting tool and anchor rod and thus cause a complete transmission of the torque and the feed, even for high values. In particular, in the application with composite dowel, the inventive device ensures a complete and handy setting of the anchor rods. In addition, the user is spared a precise positioning of the setting tool, since it is not a form fit for transmitting the torque. Furthermore, the use of the same setting tool for anchor rods of different diameters is ensured by the conical design of the recess of the setting tool and the outer contour of the anchor rod. The simple design of the anchor rod economical production of the same is possible.
Vorzugsweise weisen die konische Ausnehmung und die konische Aussenkontur einen Konuswinkel von 10° auf, um eine optimale Übertragung sicherzustellen.Preferably, the conical recess and the conical outer contour have a cone angle of 10 ° to ensure optimum transmission.
Ferner weist die konische Ausnehmung vorteilhafterweise einen Konuswinkel auf, der dem Konuswinkel der konische Aussenkontur entspricht, um die Kontaktfläche zwischen der am lastangriffseitigen Ende angeordneten konischen Aussenkontur und der konischen Ausnehmung im Setzwerkzeug zu maximieren.Furthermore, the conical recess advantageously has a cone angle which corresponds to the conical angle of the conical outer contour in order to maximize the contact surface between the conical outer contour arranged on the load engagement end and the conical recess in the setting tool.
Die konische Ausnehmung und/oder die konische Aussenkontur weisen in bevorzugter Weise zumindest teilweise eine Profilierung auf. Damit wird der Reibungskoeffizient zwischen den Kontaktflächen erhöht. Ausserdem können, um eine ähnliche Wirkung zu erzielen, auch Beschichtungen anstelle der Profilierung Anwendung finden.The conical recess and / or the conical outer contour preferably have, at least partially, a profiling. This increases the coefficient of friction between the contact surfaces. In addition, coatings can be used instead of profiling to achieve a similar effect.
Vorteilhafterweise entspricht die axiale Tiefe (T) der konischen Ausnehmung dem 0,1 bis 0,75-fachen des grössten Durchmessers der konischen Ausnehmung des Setzwerkzeuges, um die Verwendung von Ankerstangen mit unterschiedlichen Durchmessern mit demselben Setzwerkzeug zu ermöglichen. Zusätzlich wird dadurch einer Verwendung des Setzwerkzeuges mit zu grossen Ankerstangen und somit einer Überlastung des Setzwerkzeuges vorgebeugt.Advantageously, the axial depth (T) of the conical recess corresponds to 0.1 to 0.75 times the largest diameter of the conical recess of the setting tool to allow the use of anchor rods of different diameters with the same setting tool. In addition, a use of the setting tool is prevented with too large anchor rods and thus overloading the setting tool.
Die Höhe der konischen Aussenkontur entspricht vorzugsweise dem 0,1 bis 0,75-fachen des Durchmessers der Ankerstange, womit eine genügend hohe Reibkraft zwischen dem Setzwerkzeug und der Ankerstange gewährleistet ist. Je grösser der Durchmesser der Ankerstange, desto höher ist das zu übertragende Drehmoment.The height of the conical outer contour preferably corresponds to 0.1 to 0.75 times the diameter of the anchor rod, whereby a sufficiently high frictional force between the setting tool and the anchor rod is ensured. The larger the diameter of the anchor rod, the higher the torque to be transmitted.

Die Ankerstange 1 weist an ihrem lastangriffseitigen Ende eine konische Aussenkontur 3 auf, die in die Ausnehmung 4 bringbar ist.In the figure, an inventive device for feed and / or torque transmission on anchor rods 1 of dowels, in particular composite dowels, partially shown.
