Die Erfindung betrifft eine Ankervorrichtung für eine Betonwandschalung mit zwei sich gegenüber liegenden Schalungselementen, die mittels eines Ankerstabs der Ankervorrichtung miteinander verbindbar sind, wobei die Ankervorrichtung zwei Funktionseinheiten aufweist, die mit dem Ankerstab zu einer Stabilisierung der Schalungselemente verbindbar sind, wobei jedes Schalungselement Aufnahmeöffnungen aufweist, in denen wahlweise die Funktionseinheiten einsetzbar sind, wobei die Funktionseinheiten in den Aufnahmeöffnungen der Schalungselemente jeweils mittels einer Verschlusseinrichtung der Ankervorrichtung festlegbar sind.The invention relates to an anchor device for a concrete wall formwork with two formwork elements lying opposite one another, which can be connected to one another by means of an anchor rod of the anchor device, the anchor device having two functional units which can be connected to the anchor rod to stabilize the formwork elements, each formwork element having receiving openings in which the functional units can be optionally inserted, the functional units being able to be fixed in the receiving openings of the formwork elements by means of a locking device of the anchoring device.

In den Druckschriften WO 2016/026812 A1 und DE 10 2014 012 037 A1 wird eine Ankervorrichtung der eingangs genannten Art beschrieben. Die Verschlusseinrichtung der aus diesen Druckschriften vorbekannten Ankervorrichtung umfasst einen Riegelstift, der zur Festlegung und zum Lösen einer Funktionseinheit, zum Beispiel einer Ankermuttereinheit, durch axiale Kraftaufbringung, z.B. durch einen Schlag mit einem Hammer, auf sein jeweiliges Vorderende oder Hinterende zwischen einer Offenstellung und einer Schließstellung axial verstellbar ist.In the pamphlets WO 2016/026812 A1 and DE 10 2014 012 037 A1 an anchor device of the type mentioned is described. The locking device of the anchoring device known from these publications comprises a locking pin which can be axially adjusted between an open position and a closed position on its respective front end or rear end to fix and release a functional unit, for example an anchor nut unit, by applying axial force, for example by hitting it with a hammer.

Aufgabe der Erfindung ist es, eine Ankervorrichtung der eingangs genannten Art mit einer alternativen Verschlusseinrichtung bereitzustellen. Zur Lösung dieser Aufgabe wird eine Ankervorrichtung der eingangs genannten Art vorgeschlagen, die die Mittel und Merkmale des unabhängigen, auf eine derartige Ankervorrichtung gerichteten Anspruchs aufweist. Dabei wird zur Lösung der Aufgabe somit bei der eingangs genannten Ankervorrichtung vorgeschlagen, dass jede Verschlusseinrichtung der Ankervorrichtung einen Sperrstift mit einem unrunden Querschnitt an einem freien Ende aufweist. Mit dem freien Ende ist der Sperrstift in eine an einem Ende offene und an einem anderen Ende eine Nutbreitenerweiterung aufweisende Längsnut an der Funktionseinheit einführbar. Der Sperrstift ist am Schalungselement um seine Längsachse drehbar lagerbar und zwischen einer Freigabestellung und einer Sperrstellung verstellbar. In der Freigabestellung des Sperrstiftes ist das freie Ende des Sperrstiftes axial in die Längsnut einführbar. In der Sperrstellung des Sperrstiftes ist das freie Ende des Sperrstiftes zu breit, um axial in die Längsnut einführbar zu sein. Wird der Sperrstift aus seiner Sperrstellung in seine Freigabestellung gebracht, kann der Sperrstift mit seinem freien Ende durch die Längsnut in die Nutbreitenerweiterung eingeführt werden. Ist der Sperrstift mit seinem freien Ende dort angelangt, wird der Sperrstift aus seiner Freigabestellung in seine Sperrstellung gebracht. In der Sperrstellung ist das freie Ende dann so ausgerichtet, dass es zu breit ist, um in entgegengesetzter Richtung durch die Längsnut geführt zu werden. In der Sperrstellung ist das freie Ende des Sperrstiftes somit entgegen seiner axialen Einführrichtung durch die Längsnut formschlüssig in der Nutbreitenerweiterung gehalten, wodurch die Funktionseinheit in ihrer Position in der Aufnahmeöffnung des jeweiligen Schalungselements festgelegt ist.The object of the invention is to provide an anchor device of the type mentioned at the outset with an alternative locking device. To solve this problem, an anchoring device of the type mentioned at the outset is proposed which has the means and features of the independent claim directed to such an anchoring device. This becomes the solution The task thus proposed in the anchor device mentioned that each locking device of the anchor device has a locking pin with a non-round cross-section at a free end. The free end of the locking pin can be inserted into a longitudinal groove on the functional unit that is open at one end and has a groove width extension at the other end. The locking pin can be mounted on the formwork element so that it can rotate about its longitudinal axis and can be adjusted between a release position and a locking position. In the release position of the locking pin, the free end of the locking pin can be inserted axially into the longitudinal groove. When the locking pin is in the locking position, the free end of the locking pin is too wide to be insertable axially into the longitudinal groove. If the blocking pin is brought from its blocking position into its release position, the blocking pin can be inserted with its free end through the longitudinal groove into the widened groove. When the free end of the locking pin has arrived there, the locking pin is brought from its release position into its locking position. In the locked position, the free end is then aligned in such a way that it is too wide to be passed through the longitudinal groove in the opposite direction. In the locking position, the free end of the locking pin is thus held positively against its axial insertion direction by the longitudinal groove in the groove width expansion, whereby the functional unit is fixed in its position in the receiving opening of the respective formwork element.

Das freie Ende des Sperrstiftes ist also so bemessen, dass es bei in Sperrstellung befindlichem Sperrstift nicht durch die Längsnut geführt werden kann.The free end of the locking pin is dimensioned such that it cannot be guided through the longitudinal groove when the locking pin is in the locking position.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass der Ankerstab zur Verbindung mit der Funktionseinheit, insbesondere mit beiden Funktionseinheiten der Ankervorrichtung, ein Außengewinde aufweist.In one embodiment of the anchor device it is provided that the anchor rod for connection to the functional unit, in particular with both functional units Anchor device having an external thread.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass eine der zwei Funktionseinheiten eine Ankermuttereinheit aufweist, die an dem einen Schalungselement einsetzbar und darin festlegbar ist. Die Ankermuttereinheit kann ein Innengewinde aufweisen, in das der zuvor erwähnte Ankerstab mit seinem Außengewinde zur Befestigung einschraubbar ist.In one embodiment of the anchor device, it is provided that one of the two functional units has an anchor nut unit that can be used on the one formwork element and fixed therein. The anchor nut unit can have an internal thread into which the previously mentioned anchor rod can be screwed with its external thread for fastening.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass die andere der zwei Funktionseinheiten eine Wechselhülse aufweist, die der Ankermuttereinheit zugeordnet und an einem Schalungselement einsetzbar und darin festlegbar ist und einen Längskanal für eine verriegelungsfreie Aufnahme des Ankerstabes aufweist. Das Schalungselement, in das die Wechselhülse einsetzbar ist, kann ein Schalungselement sein, das der zuvor erwähnten Ankermuttereinheit gegenüberliegt.In one embodiment of the anchor device it is provided that the other of the two functional units has an interchangeable sleeve which is associated with the anchor nut unit and can be used on a formwork element and fixed therein and has a longitudinal channel for receiving the anchor rod without locking. The formwork element into which the interchangeable sleeve can be inserted can be a formwork element which faces the aforementioned anchor nut unit.

Die Wechselhülse lässt sich in die Aufnahmeöffnung eines Schalungselements der Ankervorrichtung einsetzen. Mithilfe der zuvor erläuterten Verschlusseinrichtung, die auch der Funktionseinheit zugeordnet ist, die die Wechselhülse aufweist, lässt sich die Wechselhülse in ihrer Gebrauchsstellung in der Aufnahmeöffnung festlegen. Die Montage der Ankervorrichtung wird erleichtert, da die Wechselhülse eine Längskanal aufweist, durch den der Ankerstab einfach hindurchgeführt werden kann, so dass die Wechselhülse in ihrer Gebrauchsstellung, bevor die Ankervorrichtung verspannt wird, relativ zu dem Ankerstab axial verschieblich ist. So bleibt es möglich, die Ankervorrichtung zu justieren, bevor sie durch Verspannung in ihren gebrauchsfertigen Zustand gebracht wird.The interchangeable sleeve can be inserted into the receiving opening of a formwork element of the anchoring device. With the aid of the closure device explained above, which is also associated with the functional unit that has the interchangeable sleeve, the interchangeable sleeve can be fixed in its position of use in the receiving opening. The installation of the anchor device is facilitated because the replacement sleeve has a longitudinal channel through which the anchor rod can be easily passed, so that the replacement sleeve is axially displaceable relative to the anchor rod in its position of use before the anchor device is braced. It thus remains possible to adjust the anchoring device before it is brought into its ready-to-use state by bracing.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass der Ankerstab einerseits an der einen Funktionseinheit des einen Schalungselements einschraubbar und andererseits, sich durch den Längskanal in der Wechselhülse erstreckend, mittels einer Schließeinheit der Ankervorrichtung am anderen Schalungselement arretierbar ist. Die Schließeinheit kann zur Verspannung der Ankervorrichtung, beispielsweise mittels eines Innengewindes an dem Ankerstab festgelegt werden. Über die Schließeinheit, den Ankerstab und die Wechselhülse können die zur Verspannung der Ankervorrichtung erforderlichen Kräfte aufgebracht werden.In one embodiment of the anchor device, it is provided that the anchor rod can be screwed into one functional unit of one formwork element and, on the other hand, extending through the longitudinal channel in the interchangeable sleeve, can be locked on the other formwork element by means of a locking unit of the anchor device. The closing unit can be fixed to the anchor rod for bracing the anchor device, for example by means of an internal thread. The forces required to brace the anchor device can be applied via the closing unit, the anchor rod and the interchangeable sleeve.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass zwischen den zwei sich in Gebrauchsstellung befindlichen Schalungselementen zumindest eine Distanzhülse der Ankervorrichtung anordenbar ist, durch die sich ein, beispielsweise der bereits zuvor erwähnte, Ankerstab in Gebrauchsstellung erstreckt. Bei der zuvor erläuterten Verspannung der Ankervorrichtung kann vorgesehen sein, dass die Distanzhülse zwischen den beiden Schalungselementen der Ankervorrichtung eingespannt wird/ist, so dass die beiden Schalungselemente einen durch die Distanzhülse definierten Abstand zueinander einnehmen.In one embodiment of the anchor device, at least one spacer sleeve of the anchor device can be arranged between the two formwork elements in the position of use, through which an anchor rod, for example the previously mentioned one, extends in the position of use. When bracing the anchor device as explained above, it can be provided that the spacer sleeve is/is clamped between the two formwork elements of the anchor device, so that the two formwork elements assume a distance from one another that is defined by the spacer sleeve.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass eine Drehsicherung ausgebildet ist, welche ein Überführen des Sperrstiftes aus der Freigabestellung in die Sperrstellung und/oder aus der Sperrstellung in die Freigabestellung behindert. Mithilfe der Drehsicherung lässt sich effektiv verhindern, dass der Sperrstift unbeabsichtigt aus der einen in die andere Stellung gelangt. Insbesondere dort, wo die Ankervorrichtung Vibrationen ausgesetzt ist, lässt sich mithilfe der Drehsicherung ein ungewolltes Lösen der Verschlusseinrichtung effektiv vermeiden.In one embodiment of the anchoring device, provision is made for an anti-rotation device to be formed, which prevents the locking pin from being transferred from the release position into the locking position and/or from the locking position into the release position. The anti-rotation lock effectively prevents the locking pin from accidentally shifting from one position to the other. In particular where the anchor device is exposed to vibrations, an unintentional release of the locking device can be effectively avoided with the aid of the anti-rotation device.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass die Nutbreitenerweiterung in eine in Umfangsrichtung, vorzugsweise mit einer axialen Steigung und/oder geschlossen, umlaufende Umfangsnut übergeht. Insbesondere dann, wenn die Umfangsnut geschlossen umlaufend ist und eine Steigung aufweist, kann die Nutbreitenerweiterung zum zusätzlichen Verspannen der Ankervorrichtung verwendet werden.In one embodiment of the anchor device, it is provided that the widening of the groove transitions into a circumferential groove running in the circumferential direction, preferably with an axial gradient and/or closed. In particular when the circumferential groove is closed and has a slope, the groove width extension can be used for additional bracing of the anchor device.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass ein Spannstift der Ankervorrichtung an der Aufnahmeöffnung ausgebildet ist, der bei in Gebrauchsstellung befindlicher Funktionseinheit in der Umfangsnut läuft und/oder in diese hineinreicht, insbesondere um die Funktionseinheit durch Drehen um ihre Längsachse zu verspannen.In one embodiment of the anchor device, it is provided that a dowel pin of the anchor device is formed on the receiving opening, which runs in the circumferential groove when the functional unit is in the use position and/or extends into it, in particular in order to brace the functional unit by rotating it about its longitudinal axis.

Bei einer Ausführungsform der Ankervorrichtung ist vorgesehen, dass der Sperrstift in dem Spannstift gelagert ist. Bei einer anderen Ausführungsform der Ankervorrichtung ist vorgesehen, dass der Sperrstift beabstandet von dem Spannstift angeordnet ist. Bei dieser Ausführungsform der Ankervorrichtung kann der Spannstift in einer separaten Längsnut laufen und/oder in eine separate Längsnut hineinragen.In one embodiment of the anchor device it is provided that the locking pin is mounted in the dowel pin. In another embodiment of the anchor device, it is provided that the locking pin is arranged at a distance from the roll pin. In this embodiment of the anchoring device, the dowel pin can run in a separate longitudinal groove and/or protrude into a separate longitudinal groove.

Die Erfindung wird nun anhand eines Ausführungsbeispiels näher beschrieben, ist aber nicht auf dieses Ausführungsbeispiel beschränkt. Weitere Ausführungsbeispiele ergeben sich durch Kombination der Merkmale einzelner oder mehrerer Schutzansprüche untereinander und/oder in Kombination einzelner oder mehrerer Merkmale des Ausführungsbeispiels, sofern diese Kombinationen in den Schutzumfang der Erfindung fallen, welcher nur durch die beigefügten Ansprüche definiert wird.The invention will now be described in more detail using an exemplary embodiment, but is not limited to this exemplary embodiment. Further exemplary embodiments are obtained by combining the features of individual or multiple claims with one another and/or by combining individual or multiple features of the exemplary embodiment, provided that these combinations fall within the protective scope of the invention, which is only defined by the appended claims.

Die Figuren 1 - 7 zeigen eine im Ganzen mit 1 bezeichnete Ankervorrichtung einer Betonwandschalung mit zwei sich gegenüberliegenden Schalungselementen 2 und 3, die mittels eines Ankerstabes 4 der Ankervorrichtung 1 miteinander verbunden sind.The Figures 1 - 7 show an anchoring device, generally designated 1, of a concrete wall formwork with two opposing formwork elements 2 and 3, which are connected to one another by means of an anchor rod 4 of the anchoring device 1.

Die Ankervorrichtung 1 weist zwei Funktionseinheiten 5 und 6 auf. Die Funktionseinheiten 5 und 6 sind über den Ankerstab 4 zur Stabilisierung der Schalungselemente 2 und 3 miteinander verbunden. Jedes Schalungselement 2, 3 weist Aufnahmeöffnungen 7 auf, in denen wahlweise die Funktionseinheiten 5 oder 6 eingesetzt werden können und in Gebrauchsstellung eingesetzt sind. Innerhalb jeder Aufnahmeöffnung 7 der Schalungselemente 2, 3 kann jede der Funktionseinheiten 5 und 6 mittels einer der Aufnahmeöffnung 7 zugeordneten Verschlusseinrichtung 8 festgelegt werden.The anchoring device 1 has two functional units 5 and 6 . The functional units 5 and 6 are connected to one another via the tie rod 4 in order to stabilize the formwork elements 2 and 3 . Each formwork element 2, 3 has receiving openings 7, in which either the functional units 5 or 6 can be used and are used in the position of use. Each of the functional units 5 and 6 can be fixed within each receiving opening 7 of the formwork elements 2 , 3 by means of a locking device 8 assigned to the receiving opening 7 .

Jede Verschlusseinrichtung 8 weist einen Sperrstift 9 mit einem unrunden Querschnitt an seinem freien Ende 10 auf. Mit dem freien Ende 10 kann der Sperrstift 9 in eine Längsnut 11 der jeweiligen Funktionseinheit 5, 6 eingeführt werden. Die Längsnut 11 ist an einem Ende offen und an einem anderen Ende mit einer Nutbreitenerweiterung 12 versehen. Der jeweilige Sperrstift 9 ist an seinem Schalungselement 2, 3 um seine Längsachse drehbar gelagert und kann so zwischen einer Freigabestellung und einer Sperrstellung verstellt werden.Each closure device 8 has a locking pin 9 with a non-circular cross-section at its free end 10 . The locking pin 9 can be inserted with the free end 10 into a longitudinal groove 11 of the respective functional unit 5 , 6 . The longitudinal groove 11 is open at one end and provided with a groove width extension 12 at the other end. The respective locking pin 9 is rotatably mounted on its formwork element 2, 3 about its longitudinal axis and can thus be adjusted between a release position and a locking position.

In seiner Freigabestellung (vgl. z.B. Figur 5) kann das freie Ende 10 des Sperrstiftes 9 die Längsnut 11 passieren. In seiner Sperrstellung ist das freie Ende 10 des Sperrstiftes 9 zu breit, um axial in die Längsnut 11 bzw. durch die Längsnut 11 herausgeführt zu werden. Auf diese Weise lässt sich mithilfe des Sperrstiftes 9 und aufgrund der Gestaltung seines freien Endes 10 eine Festlegung der Funktionseinheiten 5, 6 in den Aufnahmeöffnungen 7 der Schalungselemente 2 und 3 erzielen.In its release position (cf. e.g figure 5 ) the free end 10 of the locking pin 9 can pass through the longitudinal groove 11. In its locked position, the free end 10 of the locking pin 9 is too wide to be guided out axially into the longitudinal groove 11 or through the longitudinal groove 11 . This way you can with the aid of the locking pin 9 and due to the design of its free end 10, the functional units 5, 6 can be fixed in the receiving openings 7 of the formwork elements 2 and 3.

Der Ankerstab 4 ist zur Verbindung mit zumindest einer der Funktionseinheiten 5, 6 mit einem Außengewinde 13 versehen. Die Funktionseinheit 5, mit der der Ankerstab 4 verbindbar ist, umfasst eine Ankermuttereinheit 14, die an dem einen Schalungselement 2 der beiden Schalungselemente 2 und 3 in die dafür vorgesehene Aufnahmeöffnung 7 einsetzbar und darin festlegbar ist. Die Ankermuttereinheit 14 ist mit einem zu dem Außengewinde 13 des Ankerstabs 4 passenden Innengewinde 15 ausgestattet. So kann der Ankerstab 4 zuverlässig mit der Ankermuttereinheit 14 verbunden werden.The anchor rod 4 is provided with an external thread 13 for connection to at least one of the functional units 5, 6. The functional unit 5, with which the tie rod 4 can be connected, comprises an tie nut unit 14 which can be inserted into the receiving opening 7 provided for this purpose on the one formwork element 2 of the two formwork elements 2 and 3 and can be fixed therein. The anchor nut unit 14 is equipped with an internal thread 15 that matches the external thread 13 of the anchor rod 4 . Thus, the tie rod 4 can be reliably connected to the tie nut unit 14 .

Die andere Funktionseinheit 6 der beiden Funktionseinheiten 5 und 6 weist eine Wechselhülse 16 auf. Die Wechselhülse 16 ist der Ankermuttereinheit 14 zugeordnet und in das Schalungselement 3 einsetzbar, das der Ankermuttereinheit 14 gegenüberliegt. Zu diesem Zweck weist auch das Schalungselement 3 eine Aufnahmeöffnung 7 auf, die die Wechselhülse 16 in ihrer Gebrauchsstellung aufnimmt.The other functional unit 6 of the two functional units 5 and 6 has an interchangeable sleeve 16 . The interchangeable sleeve 16 is assigned to the anchor nut unit 14 and can be inserted into the formwork element 3 which is opposite the anchor nut unit 14 . For this purpose, the formwork element 3 also has a receiving opening 7, which receives the interchangeable sleeve 16 in its position of use.

Die Wechselhülse 16 ist mit einem Längskanal 17 versehen, durch den der Ankerstab 4 trotz seines Außengewindes 13 hindurchgeführt werden kann. Somit ist der Ankerstab 4 in dem Längskanal 17 der Wechselhülse 16 verriegelungsfrei aufgenommen.The interchangeable sleeve 16 is provided with a longitudinal channel 17 through which the anchor rod 4 can be passed despite its external thread 13 . Thus, the anchor rod 4 is accommodated in the longitudinal channel 17 of the interchangeable sleeve 16 without being locked.

Der Ankerstab 4 ist so einerseits an der Funktionseinheit 5 des einen Schalungselements 2, nämlich hier der Ankermuttereinheit 14, eingeschraubt und andererseits erstreckt sich der Ankerstab 4 durch den Längskanal 17 in der Wechselhülse 16. Mittels einer Schließeinheit 18 ist der Ankerstab 4 dann an dem anderen Schalungselement 3 arretiert. Die Schließeinheit 18 wird dazu auf das Außengewinde 13 des Ankerstabes 4 bis auf Anschlag an das Schalungselement 3 aufgeschraubt.The tie rod 4 is screwed on the one hand to the functional unit 5 of one formwork element 2, namely the tie nut unit 14 here, and on the other hand the tie rod 4 extends through the longitudinal channel 17 in the exchange sleeve 16. By means of a closing unit 18, the Anchor rod 4 then locked on the other formwork element 3. For this purpose, the closing unit 18 is screwed onto the external thread 13 of the anchor rod 4 until it abuts against the formwork element 3 .

Zwischen den beiden in Gebrauchsstellung der Ankervorrichtung 1 befindlichen Schalungselementen 2 und 3 ist zumindest eine Distanzhülse 19 angeordnet, durch die sich der Ankerstab 4 in Gebrauchsstellung erstreckt. Die Distanzhülse 19 gibt einen definierten Abstand zwischen den beiden Schalungselementen 2 und 3 der Ankervorrichtung 1 vor.At least one spacer sleeve 19 through which the anchor rod 4 extends in the position of use is arranged between the two formwork elements 2 and 3 that are in the position of use of the anchoring device 1 . The spacer sleeve 19 specifies a defined distance between the two formwork elements 2 and 3 of the anchoring device 1 .

Die Figuren 8 - 10 zeigen unterschiedliche Ansichten eines Sperrstiftes 9 und verdeutlichen auch eine Drehsicherung 20 für den Sperrstift 9. Mithilfe der Drehsicherung 20 wird ein unerwünschtes/unbeabsichtigtes Überführen des Sperrstiftes 9 aus der Freigabestellung in die Sperrstellung und auch aus der Sperrstellung in die Freigabestellung verhindert. Die Drehsicherung 20 umfasst zu diesem Zweck mehrere gleichmäßig um eine Drehachse des Sperrstiftes 9 verteilt angeordnete Mulden 21, in die ein Betätigungshebel 22 des Sperrstiftes 9 sowohl in Sperrstellung als auch in der Freigabestellung des Sperrstiftes 9 bewegt werden kann. Entgegen der Rückstellkraft eines in den Figuren nicht gezeigten Rückstellelementes, beispielsweise einer Rückstellfeder, der Drehsicherung 20 wird der Betätigungshebel 22 von einer Mulde 21 in eine andere Mulde 21 überführt, um den Sperrstift 9 aus der Freigabestellung in die Sperrstellung bzw. aus der Sperrstellung in die Freigabestellung zu bewegen. Die Rückstellkraft des Rückstellelements hält den Sperrstift 9 in der Mulde 21 und verhindert, dass der Sperrstift 9 aus Versehen seine Stellung ändert und dabei die VerschlussvorrichtungThe Figures 8 - 10 show different views of a locking pin 9 and also illustrate an anti-rotation device 20 for the locking pin 9. The anti-rotation device 20 prevents unwanted/unintentional transfer of the locking pin 9 from the release position to the locked position and also from the locked position to the release position. For this purpose, the anti-rotation device 20 comprises a plurality of troughs 21 distributed uniformly around an axis of rotation of the locking pin 9 , into which an actuating lever 22 of the locking pin 9 can be moved both in the locking position and in the release position of the locking pin 9 . Against the restoring force of a restoring element, not shown in the figures, for example a restoring spring, of the anti-rotation device 20, the actuating lever 22 is transferred from one trough 21 to another trough 21 in order to move the locking pin 9 from the release position to the locked position or from the locked position to the released position. The restoring force of the restoring element keeps the locking pin 9 in the trough 21 and prevents the locking pin 9 from accidentally changing its position and thereby the locking device

Die Figuren 1 - 7 verdeutlichen, dass die Nutbreitenerweiterungen 12, die an den beiden Funktionseinheiten 5, 6 und hier konkret an der Ankermuttereinheit 14 einerseits und der Wechselhülse 16 andererseits ausgebildet sind, jeweils in eine in Umfangsrichtung geschlossen umlaufende Umfangsnut 23 übergehen, die zudem eine axiale Steigung aufweist.The Figures 1 - 7 clarify that the Groove width extensions 12, which are formed on the two functional units 5, 6 and here specifically on the anchor nut unit 14 on the one hand and the interchangeable sleeve 16 on the other hand, each merge into a peripheral groove 23 that is closed in the circumferential direction and also has an axial pitch.

Jeder Funktionseinheit 5, 6 ist ferner ein Spannstift 24 zugeordnet. Die Position der Spannstifte ist gut in Figur 3 zu erkennen. Die Spannstifte 24 sind an den Aufnahmeöffnung 7 der beiden Schalungselemente 2, 3 ausgebildet. Bei in Gebrauchsstellung befindlicher Funktionseinheit 5, 6 läuft der jeweilige Spannstift in der Umfangsnut 23 bzw. ragt in diese hinein. Mithilfe der Spannstifte 24 ist es möglich, die jeweilige Funktionseinheit 5, 6 durch Drehen um Ihre Längsachse zu verspannen. Hierbei wird die zuvor bereits erwähnte axiale Steigung der jeweiligen Umfangsnut 23 mit dem ortsfest an dem jeweiligen Schalungselement 2, 3 angeordneten Spannstift 24 genutzt. Durch eine Drehung der jeweiligen Funktionseinheit 5, 6 um ihre Längsachse kann die Steigung der jeweiligen Umfangsnut 23 dazu genutzt werden, eine axiale Spannkraft zu erzeugen, die über den Spannstift 24 auf das jeweilige Schalungselement 2, 3 übertragen werden kann.Each functional unit 5, 6 is also assigned a dowel pin 24. The position of the dowel pins is good in figure 3 to recognize. The dowel pins 24 are formed on the receiving opening 7 of the two formwork elements 2, 3. When the functional unit 5, 6 is in the position of use, the respective dowel pin runs in the circumferential groove 23 or protrudes into it. With the help of the clamping pins 24, it is possible to brace the respective functional unit 5, 6 by rotating it about its longitudinal axis. Here, the previously mentioned axial pitch of the respective circumferential groove 23 is used with the stationarily arranged on the respective formwork element 2, 3 dowel pin 24. By rotating the respective functional unit 5, 6 about its longitudinal axis, the slope of the respective circumferential groove 23 can be used to generate an axial clamping force that can be transmitted to the respective formwork element 2, 3 via the dowel pin 24.
