Description

Die Erfindung betrifft ein Werkzeug zum Verankern von Spreizdübeln mittels Setzdorn mit Handgriff.The invention relates to a tool for anchoring expansion anchors by means of a setting mandrel with a handle.

Spreizdübel, welche aus einer Spreizhülse und einem Spreizkörper bestehen, werden gesetzt, indem entweder der Spreizkörper gegenüber der Spreizhülse oder die Spreizhülse gegenüber dem Spreizkörper verschoben wird. Dieses dem Setzen des Spreizdübels dienende Verschieben kann maschinell oder in überwiegendem Masse manuell mittels eines Hammers erfolgen.Expansion dowels, which consist of an expansion sleeve and an expansion body, are set by either moving the expansion body relative to the expansion sleeve or the expansion sleeve relative to the expansion body. This shifting serving to set the expansion dowel can be done mechanically or to a large extent manually using a hammer.

Beim manuellen Setzen der Spreizdübel findet in bekannter Weise ein Werkzeug Anwendung. Dieses Werkzeug ist mit einem Setzdorn versehen, wobei dieser Setzdorn schlussendlich mit dem zu verschiebenden Teil des Spreizdübels in Kontakt tritt.A tool is used in a known manner for manually setting the expansion dowels. This tool is provided with a setting mandrel, which ultimately comes into contact with the part of the expansion anchor to be displaced.

Beispielsweise aus der DE-OS 31 11 241 ist ein dem manuellen Setzen von Spreizdübeln dienendes Werkzeug bekannt. Dieses bekannte Werkzeug weist einen Handgriff auf, wobei mit diesem Handgriff der Setzdorn fest verbunden ist. Handgriff und Setzdorn sind bei diesem bekannten Werkzeug in der gleichen Achse fluchtend angeordnet. Diese Anordnung führt dazu, dass an schwer zugänglichen Stellen die Hammerschläge nicht ausreichend aufgebracht werden können, oder im Extremfalle sogar das Werkzeug nicht eingesetzt werden kann.For example, DE-OS 31 11 241 discloses a tool which is used to manually set expansion anchors. This known tool has a handle, the setting mandrel being firmly connected to this handle. In this known tool, the handle and setting mandrel are arranged in alignment on the same axis. This arrangement means that the hammer blows cannot be applied sufficiently in hard-to-reach places or, in extreme cases, the tool cannot even be used.

Da beim bekannten Werkzeug ein Setzdorn von bestimmter Grösse fest zugeordnet ist, entsteht der weitere Nachteil, dass für jede Dimension eines Spreizdübels ein gesondertes Werkzeug mit einem entsprechend abgestimmten Setzdorn verwendet werden muss.Since in the known tool a setting mandrel of a certain size is permanently assigned, there is the further disadvantage that a separate tool with a correspondingly coordinated setting mandrel must be used for each dimension of an expansion anchor.

Der Erfindung liegt die Aufgabe zugrunde, ein Werkzeug zum Verankern von Spreizdübeln zu schaffen, welches sich durch eine universelle Verwendungsmöglichkeit sowie durch Einsatzmöglichkeit auch an schwer zugänglichen Stellen auszeichnet.The invention has for its object to provide a tool for anchoring expansion anchors, which is characterized by a universal use and by use even in hard-to-reach places.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass der Handgriff des Werkzeuges zwei Aufnahmevorrichtungen für den Setzdorn aufweist und die Längsachsen der Aufnahmeöffnungen der Aufnahmevorrichtungen im Winkel zueinander stehen.According to the invention, the object is achieved in that the handle of the tool has two holding devices for the setting mandrel and the longitudinal axes of the holding openings of the holding devices are at an angle to one another.

Dadurch, dass das erfindungsgemässe Werkzeug zwei Aufnahmevorrichtungen aufweist und die Aufnahmeöffnungen dieser Aufnahmevorrichtungen im Winkel zueinander stehen, besteht die Möglichkeit, bei Beibehaltung der Richtung des Handgriffes die Richtung des in die Aufnahmevorrichtungen einzusetzenden Setzdornes zu verändern. Dadurch kann die Einwirkung der Hammerschläge gegenüber der Richtung des Handgriffes verändert werden. Dies ermöglicht eine Anpassung des Werkzeuges auf den jeweiligen Anwendungsfall, indem der Setzdorn in die jeweils dem Anwendungsfall entsprechende Aufnahmevorrichtung eingesetzt wird. Insbesondere besteht auch die Möglichkeit, von vornherein das Werkzeug mit zwei Setzdornen zu bestücken, wobei diese Setzdorne unterschiedlich dimensioniert sein können, so dass damit verschiedene Dimensionen von Spreizdübeln abdeckbar sind.Because the tool according to the invention has two receiving devices and the receiving openings of these receiving devices are at an angle to one another, there is the possibility of changing the direction of the setting mandrel to be inserted into the receiving devices while maintaining the direction of the handle. This allows the impact of the hammer blows to be changed with respect to the direction of the handle. This enables the tool to be adapted to the respective application by inserting the setting mandrel into the receiving device corresponding to the application. In particular, there is also the possibility of equipping the tool with two setting mandrels from the outset, these setting mandrels being able to have different dimensions, so that different dimensions of expansion anchors can thus be covered.

In bevorzugter Weise stehen die Längsachsen der Aufnahmeöffnungen unter einem Winkel von 90° zueinander. Die in der Praxis vorkommenden Anwendungsfälle haben gezeigt, dass mit einem diesbezüglich dimensionierten Winkel ein Grossteil der Anwendungen abgedeckt werden kann.The longitudinal axes of the receiving openings are preferably at an angle of 90 ° to one another. The use cases occurring in practice have shown that a large part of the applications can be covered with an angle dimensioned in this regard.

Um die Verwendung unterschiedlich dimensionierter Setzdorne in den Aufnahmevorrichtungen zu ermöglichen, ist vorzugsweise der lichte Querschnitt der Aufnahmeöffnungen veränderbar. Diese Veränderbarkeit des Querschnittes hat im wesentlichen zwei Funktionen. Zum einen dient sie - wie bereits darauf hingewiesen - der Anpassung an unterschiedlich dimensionierte Setzdorne und zum anderen wird dadurch die Haltefunktion der Setzdorne unter kraftschlüssigem Spannen bewerkstelligt.In order to enable the use of differently dimensioned setting mandrels in the receiving devices, the clear cross section of the receiving openings can preferably be changed. This changeability of the cross section essentially has two functions. On the one hand, it serves - as already pointed out - to adapt to differently dimensioned setting mandrels and, on the other hand, the holding function of the setting mandrels is accomplished with non-positive tensioning.

In bevorzugter Weise ist wenigstens eine der Aufnahmevorrichtungen nach Art einer Spannzange ausgebildet. Es kann sich dabei zweckmässigerweise um die übliche Art der Ausbildung einer Spannzange handeln, wobei federnde Elemente von einer Überwurfmutter betätigt werden. In bevorzugter Weise handelt es sich um Elemente, die unter Federkraft zum Zentrum der Aufnahmeöffnung hin wirken, um so eine Selbsthemmung der einzusetzenden Setzdorne zu erreichen. Dadurch ist in gewisser Weise eine Verliersicherung gegeben, wenn beispielsweise eine Anwendung auf einem Gerüst oder dergleichen erfolgt.At least one of the holding devices is preferably designed in the manner of a collet. It can expediently be the usual way of forming a collet, with resilient elements being actuated by a union nut. These are preferably elements which act under spring force towards the center of the receiving opening in order to achieve self-locking of the setting mandrels to be used. This is in certain Given a loss protection, if, for example, an application is made on a scaffold or the like.

Die Erfindung wird anhand einer Zeichnung, die ein Ausführungsbeispiel wiedergibt, näher erläutert.The invention will be explained in more detail with reference to a drawing which shows an embodiment.

Das Werkzeug zum Verankern von Spreizdübeln besteht aus einem Handgriff 1, einem den Handgriff 1 radial überragenden, scheibenförmigen, einstückig mit dem Handgriff 1 verbundenen Schlagschutz 1a, der beim Abgeben von Hammerschlägen auf eine Schlagstange 7 das Verletzen der Hand verhindert. Der Handgriff 1 besitzt eine zentrale Durchgangsbohrung 1e, ein Innengewinde 1d, zwei Erweiterungen 1b, 1g der zentralen Durchgangsbohrung 1e in beiden Endbereichen des Handgriffes 1 und ein Aussengewinde 1f in jenem Endbereich, der dem Schlagschutz 1a gegenüberliegt. Am Handgriff 1 sind zwei Aufnahmevorrichtungen 2, 10 angeordnet, wobei die erste Aufnahmevorrichtung 10 in einem ersten freien Endbereich des Handgriffes 1 angeordnet ist. Die zentrale Durchgangsbohrung 1e dient der Aufnahme einer radial zusammendrückbaren Doppel-Konus-Spannhülse 12. Der Handgriff 1 ist in jenem ersten Endbereich mit einem Aussengewinde 1f versehen, das mit einem Innengewinde 11a einer Spannmutter 11 zusammenwirkt. Beim Verdrehen der Spannmutter 11 gegenüber dem Handgriff 1 erfolgt eine axiale Versetzung der Spannmutter 11 gegenüber dem Handgriff 1 und ein Verspannen bzw. ein Lösen der Doppel-Konus-Spannhülse 12. Sowohl die Erweiterung 1g als auch die Spannmutter 11 besitzen konische Flächen 1c, 11a, die mit den konisch ausgebildeten Endbereichen der Doppel-Konus-Spannhülse 12 zusammenwirken.The tool for anchoring expansion anchors consists of a handle 1, a disk-shaped, radially projecting beyond the handle 1, which is integrally connected to the handle 1 and which protects the hand from being injured when a hammer 7 is struck by a hammer 7. The handle 1 has a central through-hole 1e, an internal thread 1d, two extensions 1b, 1g of the central through-hole 1e in both end regions of the handle 1 and an external thread 1f in that end region which is opposite the impact protection 1a. Two holding devices 2, 10 are arranged on the handle 1, the first holding device 10 being arranged in a first free end region of the handle 1. The central through-bore 1e serves to receive a radially compressible double-cone clamping sleeve 12. The handle 1 is provided in that first end region with an external thread 1f which interacts with an internal thread 11a of a clamping nut 11. When the clamping nut 11 is rotated relative to the handle 1, the clamping nut 11 is axially displaced relative to the handle 1 and the double-cone clamping sleeve 12 is tensioned or released. Both the extension 1g and the clamping nut 11 have conical surfaces 1c, 11a which cooperate with the conical end regions of the double-cone clamping sleeve 12.

Ferner ist ein Setzdorn 13 angedeutet, der in die Aufnahmevorrichtung 10 einsetzbar ist, in der ein radiales Verspannen der Doppel-Konus-Spannhülse 12 möglich ist.Furthermore, a setting mandrel 13 is indicated, which can be inserted into the receiving device 10, in which a radial clamping of the double-cone clamping sleeve 12 is possible.

Die zweite Aufnahmevorrichtung 2 ist im zweiten Endbereich des Handgriffes 1 angeordnet und besteht im wesentlichen aus zwei kreisrunden Spannscheiben 3, 4, wobei die Spannscheibe 4 im stirnseitigen Bereich 4a eine Aufnahmeöffnung für einen Setzdorn 8 aufweist und drehfest mit einer Schlagstange 7 verbunden ist. Die drehfeste Verbindung erfolgt mittels eines Sicherungsstiftes 6, der mit einer Scheibe 5 mit unregelmässiger Aussenkontur mit der Schlagstange 7 in Verbindung steht. Die unregelmässige Aussenkontur der Scheibe 5 entspricht einer stimseitig angeordneten unregelmässigen Kontur einer Vertiefung der Spannscheibe 4. Die Vertiefung liegt der Aufnahmeöffnung gegenüber.The second holding device 2 is arranged in the second end area of the handle 1 and essentially consists of two circular tensioning disks 3, 4, the tensioning disk 4 having a receiving opening for a setting mandrel 8 in the front area 4a and being connected in a rotationally fixed manner to an impact bar 7. The rotationally fixed connection is made by means of a locking pin 6, which is connected to the beater bar 7 by means of a disc 5 with an irregular outer contour. The irregular outer contour of the disc 5 corresponds to an irregular contour of an indentation of the tensioning disc 4 arranged on the end side. The indentation lies opposite the receiving opening.

Die Schlagstange 7 ist teilweise mit einem Aussengewinde 7a versehen, das mit einem Innengewinde 1d des Handgriffes 1 zusammenwirkt. Durch Verdrehen des Handgriffes 1 gegenüber der Schlagstange 7 erfolgt eine axiale Versetzung der drehfest mit der Schlagstange 7 verbundenen Spannscheibe 4. Die dem Schlagschutz 1a am nächsten angeordnete Spannscheibe 3 ist drehbar und axial versetzbar auf der Schlagstange 7 angeordnet.The beater bar 7 is partially provided with an external thread 7a which interacts with an internal thread 1d of the handle 1. By turning the handle 1 relative to the impact bar 7, the tensioning disk 4 is connected to the impact bar 7 in a rotationally fixed manner. The tensioning disk 3 arranged closest to the impact protection 1 a is rotatable and axially displaceable on the impact bar 7.

In der radialen Erweiterung 1b der zentralen Durchgangsbohrung 1e des Handgriffes ist eine Druckfeder 9 angeordnet, die auf die Spannscheibe 3 drückt und auf der Schlagstange 7 frei drehbar ist. Der zwischen dem stirnseitigen Bereich 3a der Spannscheibe 3 und der Aufnahmeöffnung der drehfest mit der Schlagstange 7 verbundenen Spannscheibe 4 angeordnete Setzdorn 8 steht auch dann unter Vorspannung, wenn sich die zweite Aufnahmevorrichtung 2 im entspannten Zustand befindet.In the radial extension 1b of the central through bore 1e of the handle, a compression spring 9 is arranged, which presses on the tensioning disk 3 and is freely rotatable on the striker bar 7. The setting mandrel 8, which is arranged between the end area 3a of the tensioning disk 3 and the receiving opening of the tensioning disk 4, which is non-rotatably connected to the impact rod 7, is also under tension when the second receiving device 2 is in the relaxed state.
