Beschreibung Einschlaganker Description Impact anchor

Die Erfindung betrifft einen Einschlaganker mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an impact anchor with the features of the preamble of claim 1.

Aus der DE 31 02 708 A1 ist ein derartiger Einschlaganker bekannt. Der bekannte Einschlaganker weist ein zylindrisches Ankergrundteil mit einem in Längsrichtung verlaufenden Loch auf, das sich auf einem Teil seiner Länge zu einem Ende des Ankergrundteils hin verjüngt. Um das Ankergrundteil aufspreizen zu können weist es Schlitze in dem Bereich auf, in dem sich das Loch verjüngt. Der Längsbereich desSuch an impact anchor is known from DE 31 02 708 A1. The known drop-in anchor has a cylindrical anchor base part with a longitudinally extending hole which tapers over part of its length towards one end of the anchor base part. In order to be able to spread the anchor base part, it has slots in the area in which the hole tapers. The longitudinal area of the

Ankergrundteils, in dem sich die Verjüngung des Lochs und die Schlitze befinden, kann auch als Spreizbereich bezeichnet werden. Im Loch des Ankergrundteils ist ein bolzen- oder stiftförmiger Spreizkörper aufgenommen, der in die Verjüngung des Lochs des Ankergrundteils verschiebbar ist und dabei das Ankergrundteil im Spreizbereich aufweitet bzw. aufspreizt. Auf diese Weise lässt sich der Einschlaganker in einemThe base part of the anchor, in which the taper of the hole and the slots are located, can also be referred to as the expansion area. A bolt-shaped or pin-shaped expansion body is accommodated in the hole of the anchor base part, which can be displaced into the taper of the hole in the anchor base part and thereby expands or spreads the anchor base part in the expansion area. In this way, the drop anchor can be integrated in one

Der Erfindung liegt die Aufgabe zugrunde, einen Einschlaganker der vorstehend erläuterten Art mit einer verbesserten Verankerung vorzuschlagen.The object of the invention is to propose an impact anchor of the type explained above with an improved anchorage.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Das Ankergrundteil des erfindungsgemäßen Einschlagankers weist Kanten an seiner Außenseite auf, die in einem Winkel zu seiner Längsrichtung verlaufen. Unter Kanten im Sinne der Erfindung können bspw. auch Rippen oder dgl. verstanden werden. Die Kanten verlaufen bspw. wendeiförmig auf der Außenseite des Ankergrundteils. Beim Einbringen desThis object is solved by the features of claim 1. The anchor base part of the impact anchor according to the invention has edges on its outside which run at an angle to its longitudinal direction. Edges in the sense of the invention can also be understood to mean, for example, ribs or the like. The edges run, for example, helically on the outside of the base part of the anchor. When inserting the

Einschiagankers in ein Bohrloch und/oder beim Aufspreizen des Ankergrundteils drücken sich die Kanten des Ankergrundteils in eine Bohrlochwandung ein und bewirken einen Formschluss bei der Verankerung des Einschiagankers im Bohrloch zusätzlich zu einem durch das Aufspreizen des Ankergrundteils bewirkten Kraftschluss. Eine Verankerungskraft ist dadurch erhöht. Des Weitern wirken die Kanten einemInsertion anchor in a borehole and / or when spreading the anchor base part, the edges of the anchor base press into a borehole wall and bring about a positive fit when anchoring the insertion anchor in the borehole in addition to a non-positive connection caused by the spreading of the anchor base part. Anchoring force is increased. Furthermore, the edges have an effect

Torsionsmoment bei einer Befestigung eines Gegenstands am Einschlaganker durch Anschrauben entgegen. Außerdem wird ein Torsionsmoment durch die Kanten auch außerhalb eines Spreizbereichs auf die Bohrlochwand übertragen.Torsional moment when attaching an object to the impact anchor Screw it on. In addition, a torsional moment is transmitted through the edges to the borehole wall outside of an expansion area.

Eine Ausgestaltung der Erfindung sieht vor, dass das Ankergrundteil einen Mehrkant mit wendeiförmig verlaufenden Kanten aufweist. Dieses Ankergrundteil lässt sich einfach und preisgünstig durch Verdrehen eines Mehrkants mit ursprünglich gerade verlaufenden Kanten herstellen.An embodiment of the invention provides that the anchor base part has a polygon with helical edges. This anchor base part can be produced easily and inexpensively by twisting a polygon with originally straight edges.

Die Kanten des Ankergrundteils verlaufen vorzugsweise in der selben Richtung schräg wie ein Gewinde, das zur Befestigung eines Gegenstands am Ankergrundteil ausgebildet ist. Bei einem Rechtsgewinde verlaufen die Kanten also ebenfalls rechtsgängig, wobei die Kanten vorzugsweise sehr steil, d.h. in einem spitzen Winkel zu einer Längsrichtung des Ankergrundteiis verlaufen.The edges of the anchor base part preferably run obliquely in the same direction as a thread which is designed to fasten an object to the anchor base part. In the case of a right-hand thread, the edges also run right-hand, the edges preferably being very steep, i.e. run at an acute angle to a longitudinal direction of the anchor base part.

Eine Ausgestaltung der Erfindung sieht eine Rückschiebesicherung des Spreizkörpers vor. Diese hat den Zweck, eine Rückverschiebung des Spreizkörpers aus der Verjüngung des Lochs im Ankergrundteils heraus zu vermeiden. Der Spreizkörper kann bspw. eine Tannenbaumprofilierung als Rückschiebesicherung aufweisen, die einer Verschiebung des Spreizkörpers entgegen der Verjüngung des Lochs im Ankergrundteil entgegenwirkt. Diese Ausgestaltung kann auch unabhängig von anderen Merkmalen beiOne embodiment of the invention provides a push-back safety device for the expansion body. The purpose of this is to prevent the expansion body from moving back out of the tapering of the hole in the base part of the anchor. The expansion body can, for example, have a fir tree profiling as a slide-back protection, which counteracts a displacement of the expansion body against the tapering of the hole in the base part of the anchor. This configuration can also be independent of other features

Der in der Zeichnung dargestellte, erfindungsgemäße Einschlaganker 10 weist einThe impact anchor 10 according to the invention shown in the drawing has a

Ankergrundteil 12 auf, das aus einem Mehrkant hergestellt ist. Im dargestellten und beschriebenen Ausführungsbeispiel ist zur Herstellung des Ankergrundsteils 12 ein Sechskantstab aus Stahl verwendet worden. Der Sechskantstab ist um seine gedachte Achse verdreht worden, so dass Kanten 14 des Mehrkants wendeiförmig, d.h. in einem Winkel zu einer Längsrichtung des Ankergrundteils 12 verlaufen. Die Kanten 14 sind rechtsgängig, sie weisen eine sehr große Steigung auf, sie verlaufen in einem spitzen Winkel zu einer Längsrichtung des Ankergrundteils 12.Anchor base part 12, which is made of a polygon. In the illustrated and described embodiment, a hexagonal steel rod has been used to manufacture the anchor base part 12. The hexagonal rod is around its imaginary Axis has been rotated so that edges 14 of the polygon extend helically, ie at an angle to a longitudinal direction of the anchor base part 12. The edges 14 are right-handed, they have a very large slope, they run at an acute angle to a longitudinal direction of the anchor base part 12.

Von einem Ende aus ist das Ankergrundteil 12 mit quer durchgehenden, einander kreuzenden Längsschlitzen 16 versehen, die sich über etwas weniger als eine Hälfte einer Länge des Ankergrundteils 12 erstrecken.From one end, the anchor base part 12 is provided with transverse, intersecting longitudinal slots 16, which extend over a little less than half a length of the anchor base part 12.

Das Ankergrundteil 12 weist ein axiales Durchgangsloch 18 auf, das sich im Bereich derThe anchor base part 12 has an axial through hole 18, which is in the area of the

Längsschlitze 16 konisch verjüngt und das außerhalb der Längsschnitze 16 zylindrisch ist. Die Längsschlitze 16 bzw. der sich verjüngende Teil 20 des Durchgangslochs 18 definieren einen Spreizbereich 22 des Ankergrundteils 12. Der zylindrische Teil des Durchgangslochs 18 ist mit einem Innengewinde 24 versehen.Longitudinal slots 16 taper conically and which is cylindrical outside the longitudinal slots 16. The longitudinal slots 16 or the tapering part 20 of the through hole 18 define an expansion area 22 of the anchor base part 12. The cylindrical part of the through hole 18 is provided with an internal thread 24.

Im Durchgangsloch 18 ist ein Spreizkörper 26 verschiebbar aufgenommen. Der Spreizkörper 26 weist einen zylindrischen Abschnitt 28 und einen zur Verjüngung 20 des Durchgangslochs 18 komplementären konischen Abschnitt 30 auf. Ein Durchmesser des zylindrischen Abschnitts 28 des Spreizkörpers 26 entspricht einem Durchmesser des zylindrischen Teils des Durchgangslochs 18 des Ankergrundteils 12. Im konischenIn the through hole 18, an expansion body 26 is slidably received. The expansion body 26 has a cylindrical section 28 and a conical section 30 which is complementary to the taper 20 of the through hole 18. A diameter of the cylindrical section 28 of the expansion body 26 corresponds to a diameter of the cylindrical part of the through hole 18 of the anchor base part 12. In the conical

Abschnitt 30 weist der Spreizkörper eine Tannenbaumprofilierung 32 auf, die eine Rückschiebesicherung bildet. In das Innengewinde 24 des Durchgangslochs 18 des Grundkörpers 12 ist eine Kunststoffscheibe 35 als Verliersicherung eingesetzt, die den Spreizkörper 26 im Durchgangsloch 18 des Grundkörpers 12 hältIn section 30, the expansion body has a fir tree profiling 32, which forms a push-back protection. In the internal thread 24 of the through hole 18 of the base body 12, a plastic washer 35 is inserted as an anti-loss device, which holds the expansion body 26 in the through hole 18 of the base body 12

Zur Verankerung in einem nicht dargestellten Bohrloch wird der Einschlaganker 10 bspw. mit Hammerschlägen in das Bohrloch eingeschlagen, wobei sich der Spreizbereich 22 in Einschlagrichtung vorn befindet. Der Einschlaganker 10 wird bündig im Bohrloch versenkt. Anschließend wird in einem nicht dargestellten Einschlagdorn oder durch Eindrehen einer Schraube in das Innengewinde 24 der Spreizkörper 26 in dieFor anchoring in a borehole (not shown), the impact anchor 10 is hammered into the borehole, for example with hammer blows, the expansion region 22 being located at the front in the direction of impact. The impact anchor 10 is sunk flush into the borehole. Subsequently, the expansion body 26 is in a wrench, not shown, or by screwing a screw into the internal thread 24

Verjüngung 20 des Durchgangslochs 18 verschoben. Der Spreizköφer 26 weitet oder spreizt das Ankergrundteil 12 im Spreizbereich 22 auf und verankert auf diese Weise den Einschlaganker 10 im Bohrloch. Die die Rückschiebesicherung bildende Tannenbaumprofilierung 32 des Spreizkörpers 26 verhindert, dass sich der Spreizkörper 26 zurück aus der Verjüngung 20 heraus verschiebt und hält den Einschlaganker 10 aufgespreizt.Taper 20 of the through hole 18 shifted. The expansion body 26 expands or spreads the anchor base part 12 in the expansion area 22 and in this way anchors the impact anchor 10 in the borehole. The fir tree profiling 32 of the expansion body 26, which forms the anti-retraction device, prevents the expansion body from moving 26 moves back out of the taper 20 and keeps the impact anchor 10 spread.

Beim Einschlagen des Einschiagankers 10 in das Bohrloch drücken sich die Kanten 14 des Ankergrundteils 12 in eine Bohrlochwandung ein. Ebenfalls beim Aufspreizen drücken sich die Kanten 14 im Spreizbereich 22 in die Bohrlochwandung ein. Auf diese Weise ergibt sich eine formschlüssige Verankerung des Einschiagankers 10 im Bohrloch zusätzlich zu einer kraftschlüssigen Verankerung durch das Aufspreizen des Ankergrundteils 12. Die Verankerung ist dadurch verbessert.When the insertion anchor 10 is driven into the borehole, the edges 14 of the anchor base part 12 press into a borehole wall. Also when spreading, the edges 14 in the expansion area 22 press into the borehole wall. In this way, there is a positive anchoring of the insertion anchor 10 in the borehole in addition to a non-positive anchoring by spreading the anchor base part 12. The anchoring is thereby improved.

Mit einer nicht dargestellten Schraube lässt sich ein nicht dargestellter Gegenstand am Innengewinde 24 des Einschiagankers 10 befestigen.An object, not shown, can be fastened to the internal thread 24 of the insertion anchor 10 with a screw, not shown.

Das Innengewinde 24 ist ein Rechtsgewinde, es steigt also in der selben Drehrichtung wie die Kanten 14 des Ankergrundteils 10, auch wenn die Steigungen der Kanten 14 und des Innengewindes 24 völlig unterschiedlich sind. Dadurch wirken die Kanten 14 einem Drehmoment beim Eindrehen und Anziehen einer Schraube in das Innengewinde 24 entgegen. The internal thread 24 is a right-hand thread, so it rises in the same direction of rotation as the edges 14 of the anchor base part 10, even if the slopes of the edges 14 and the internal thread 24 are completely different. As a result, the edges 14 counteract a torque when screwing in and tightening a screw into the internal thread 24.
