Description

Die Erfindung betrifft ein Ankersystem einer Betonwandschalung mit mindestens einer Arretiervorrichtung für einen Ankerstab des Ankersystems, wobei die Arretiervorrichtung ein Schraubenmutterelement zum Durchschrauben des Ankerstabs durch ein Schraubenmuttergewinde des Schraubenmutterelements aufweist.The invention relates to an anchor system of a concrete wall formwork with at least one locking device for an anchor rod of the anchor system, wherein the locking device has a nut element for screwing through the anchor rod by a nut thread of the nut member.

Derartige Ankersysteme werden in der Schalungstechnik beim Betonieren von Stahlbetonbauten eingesetzt. Betonwandschalungen sind aus einer Schalhaut und dessen stützende Elemente, z.B. Längsträger und Querriegel, aufgebaut. Die beiden Seiten einer Wand werden aus jeweils einem Betonschalungselement, d.h. einer Schalungshälfte, gebildet, welche durch Ankerstäbe zusammengehalten werden. Die Ankerstäbe werden durch Bohrungen in der Schalhaut hindurch gesteckt und an ihren Enden an den die Schalhaut stützenden Elementen so befestigt, dass die beim Betonieren auf die Ankerstäbe wirkende Zugkraft aufgenommen wird. Üblicherweise weisen die beiden Enden der Ankerstäbe Gewinde auf, auf welche Schraubenmuttern als Ankerfixierungen aufgeschraubt werden. Dadurch wird die wirksame Länge des Ankerstabs und damit die Stärke (Dicke) der zu betonierenden Wand festgelegt. Gleichzeitig wird der beim Betonieren vom flüssigen Beton auf die Schalhaut ausgeübte Druck über die Schraubenmuttern auf die Ankerstäbe abgeleitet. Die Ankerstäbe werden dabei auf Zug belastet. Zwischen den Schalhäuten werden Abstandshalter in das Volumen der zu betonierenden Wand eingebracht, welche die beim Betoniervorgang entstehenden Druckkräfte aufnehmen können, wodurch sichergestellt wird, dass diese Druckkräfte die Wandstärke nicht unerwünscht beeinflussen, d.h. vermindern.Such anchor systems are used in formwork technology in concreting reinforced concrete structures. Concrete wall formworks are made of a formwork skin and its supporting elements, e.g. Side member and cross bar, constructed. The two sides of a wall are each made up of a concrete formwork element, i. a formwork half, formed, which are held together by anchor rods. The anchor rods are inserted through holes in the formwork skin and attached at their ends to the formwork supporting the elements so that the force acting on the anchor rods during concreting tensile force is absorbed. Usually, the two ends of the anchor rods have threads on which nuts are screwed as Ankerfixierungen. As a result, the effective length of the anchor rod and thus the strength (thickness) of the wall to be concreted is determined. At the same time, the pressure exerted on the formwork by the liquid concrete during concreting is dissipated via the nuts on the tie rods. The tie rods are loaded on train. Spacers are inserted between the shell skins in the volume of the wall to be concreted, which can accommodate the pressure forces generated during the concreting process, thereby ensuring that these compressive forces do not affect the wall thickness undesirable, i. Reduce.

Die DE 197 54 366 C2 offenbart ein Ankersystem einer Betonwandschalung, bei der eine Arretiervorrichtung auf einer Seite einer Betonwandschalung vorgesehen ist. Die Arretiervorrichtung besteht aus einer Lagefixierung einer Schraubenmutter des Ankersystems. Die Schraubenmutter ist durch quer zu ihrer Achse verlaufende, in einem Querriegel befestigte Arretierungsschrauben lagefixiert, wodurch die lagefixierte Schraubenmutter nicht weiter drehbar ist. Durch diese Lagefixierung wird, bedingt durch die Befestigung der Arretierungsschrauben am Querriegel, auch die Schraube relativ zu einer Schalungshälfte arretiert.The DE 197 54 366 C2 discloses an anchor system of a concrete wall formwork in which a locking device is provided on one side of a concrete wall formwork. The locking device consists of a positional fixation of a nut of the anchor system. The nut is fixed in position by transverse to its axis, fixed in a cross bar locking screws, whereby the position-fixed nut is no longer rotatable. As a result of this positional fixation, the screw is also locked relative to a formwork half due to the fastening of the locking screws on the crossbar.

Die DE 103 36 414 B4 offenbart ein Ankersystem, wobei auf den Rückseiten zweier eine Betonwandschalung ausbildender Schalungselemente, durch die ein Ankerstab des Ankersystems durchgeführt ist, jeweils eine sehr flexible Arretiervorrichtung vorgesehen ist, mittels derer sowohl Zug als auch Druckkräfte auf die Schalungselemente so aufgenommen werden können, dass die auszubildende Betonwandstärke sehr exakt ausgeformt werden kann.The DE 103 36 414 B4 discloses an anchor system, wherein on the backs of two forming a concrete wall formwork formwork elements through which an anchor rod of the anchor system is carried out, respectively a very flexible locking device is provided, by means of which both train and compressive forces can be absorbed on the formwork elements so that the trainees concrete wall thickness can be formed very accurately.

Bei den bekannten Ankersystemen ergeben sich Schwierigkeiten bei der Durchführung des Ankerstabes beim Aufbau der Betonwandschalung, sobald die sich mit ihren Schalhäuten gegenüberstehenden, die auszuformende Betonwand abformenden Schalungselemente mit ihren Ankerdurchführungsbohrungen nicht ausreichend fluchtend gegenüberstehen. Da der Ankerstab immer von außen, von der Rückseite eines ersten Schalungselements aus gesehen, durch die bereits aufgestellten Schalungselemente hindurch geführt wird, kann der Schalungsbauer, der den Ankerstab positioniert, die Ankerdurchführungsbohrung des zweiten Schalungselements nicht sehen. Zwar wird noch verhältnismäßig leicht die letztgenannte Ankerdurchführungsbohrung gefunden, jedoch steht bei schlecht fluchtenden Ankerdurchführungsbohrungen der Ankerstab dann schräg zur Schalhaut der Schalungselemente, wodurch das Finden des Gewindes einer auf der Rückseite des zweiten Schalungselements befestigten Arretiervorrichtung sehr erschwert wird. Weiter liegen bei einer derartigen Schrägstellung des Ankerstabes die Arretiervorrichtungen nicht mehr vollumfänglich bündig an den Schalungselementen an, was zu einer nur punktuellen Kraftübertragung bei einem Betoniervorgang der auftretenden Kräfte von der Betonwandschalung auf die Arretiervorrichtungen führt und diese stark beansprucht.In the known anchor systems arise difficulties in the implementation of the anchor rod in the construction of the concrete wall formwork, as soon as facing with their Schalhäuten, auszuformende the concrete wall forming formwork elements with their anchor bushing holes are not sufficiently aligned. Since the anchor rod is always seen from the outside, viewed from the back of a first formwork element, through the already established formwork elements, the formwork builder who positions the tie rod, the anchor passage bore of the second formwork element can not see. Although the latter anchor bushing is still relatively easy to find, however, the anchor rod is then obliquely to the formwork of the formwork elements in poorly aligned anchor bushing holes, whereby finding the thread of a fastened on the back of the second formwork element Arresting device is very difficult. Further, in such an inclined position of the anchor rod, the locking devices are no longer fully flush with the formwork elements, resulting in only a selective power transmission in a concreting of the forces occurring from the concrete wall formwork on the locking devices and this heavily used.

Die DE 94 12 556 U offenbart eine Arretiervorrichtung für einen Ankerstab eines Ankersystems einer Betonwandschalung, mit einem Schraubenmutterelement zum Durchschrauben des Ankerstabs, wobei eine Kalottenplatte vorgesehen ist, die einen sphärisch ausgebildeten Plattenbereich mit einer Öffnung aufweist. Das Schraubenmutterelement ist derart sphärisch ausgebildet, dass es innerhalb der Ränder der Öffnung ähnlich einem Kugelgelenk beweglich gelagert ist, wobei eine radiale Verdrehung des Schraubenmutterelements in der Öffnung durch axiale nutartige Führungen verhindert wird.The DE 94 12 556 U discloses a locking device for an anchor rod of a bolting system of a concrete wall formwork, comprising a nut member for screwing through the anchor rod, wherein a dome plate is provided which has a spherical plate portion having an opening. The nut member is formed to be spherical so as to be movably supported within the edges of the opening similarly to a ball joint, whereby radial rotation of the nut member in the opening is prevented by axial groove-like guides.

Bei einer derartigen Lagerung des Schraubenmutterelements in der Kalottenplatte ist der in das Schraubenmutterelement eingeschraubte Ankerstab nur sehr genau geführt beweglich. Die Kalottenplatte muss daher relativ zur Ankerdurchführung in einer Schalhaut exakt positioniert werden.In such a bearing of the nut member in the dome plate of the screwed into the nut member anchor rod is only very accurately guided movable. The dome plate must therefore be positioned accurately relative to the anchor bushing in a formwork skin.

Die EP 0 279 046 weist die Merkmale des Oberbegriffs des Anspruchs 1 auf und beschreibt eine Arretiervorrichtung für einen Ankerstab eines Ankersystems einer Betonwandschalung, mit einem Schraubenmutterelement zum Durchschrauben des Ankerstabs, wobei das Schraubenmutterelement eine radial umlaufende Nut aufweist. Es ist eine Ankerplatte vorgesehen, die eine Öffnung aufweist in der die Nut mit einem radialen Spiel angeordnet ist. Dabei kann das Schraubenmutterelement nur geringfügig in der Ankerplatte gekippt werden, wobei sich die Drehachse bei diesem Kippen entsprechend der Krümmung einer Zwischenschicht auf der schalungsabgewandten Seite des Schraubenmutterelements befindet.The EP 0 279 046 has the features of the preamble of claim 1 and describes a locking device for an anchor rod of an anchor system concrete wall formwork, with a nut member for screwing through the anchor rod, wherein the nut member has a radially circumferential groove. It is provided an anchor plate having an opening in the groove with a radial clearance is arranged. In this case, the nut element can be tilted only slightly in the anchor plate, wherein the axis of rotation is in this tilting according to the curvature of an intermediate layer on the side facing away from the formwork of the screw nut element.

Der Erfindung liegt die Aufgabe zugrunde, ein Ankersystem für Betonwandschalungen, eine Arretiervorrichtung für das Ankersystem und eine Betonwandschalung bereitzustellen, welche die Nachteile des Standes der Technik vermeiden.The invention has for its object to provide an anchor system for concrete wall formwork, a locking device for the anchor system and a concrete wall formwork, which avoid the disadvantages of the prior art.

Diese Aufgabe wird durch die Vorrichtungen der unabhängigen Ansprüche gelöst. Die abhängigen Ansprüche stellen bevorzugte Ausführungsformen der Erfindung dar.This object is solved by the devices of the independent claims. The dependent claims represent preferred embodiments of the invention.

Eine erfindungsgemäße Arretiervorrichtung für einen Ankerstab eines Ankersystems einer Betonwandschalung mit einem ersten und einem zweiten Schalungselement weist ein Schraubenmutterelement zum Durchschrauben des Ankerstabs durch ein Schraubenmuttergewinde des Schraubenmutterelements auf. Es ist eine Kalottenplatte vorgesehen, die mittels Befestigungsmitteln an einer Rückseite eines der Schalungselemente der Betonwandschalung, also der von der betonseitigen Schalhautoberfläche abgewandten üblicherweise Längs- und/oder Querriegel aufweisenden Seite des Schalungselements, befestigbar ist. Die Kalottenplatte weist einen sphärisch ausgebildeten Plattenbereich mit einer Öffnung auf, in der das Schraubenmutterelement mit radialem Spiel angeordnet ist. Das Schraubenmutterelement weist eine nutartig radial umlaufende Aufnahme auf, in der die Ränder der Öffnung im sphärischen Plattenbereich aufgenommen sind. Das radiale Spiel ist umlaufend vorhanden, so dass innerhalb des radialen Spiels eine vollumfängliche Auslenkung des Schraubenmutterelements auf der Kalottenplatte ermöglicht ist. Dadurch ergibt sich ein Drehpunkt des bevorzugt eine Kalottenmutter umfassenden Schraubenmutterelements im Bereich der Ankerdurchführungsbohrung in der Schalhaut. Der Radius des sphärischen Plattenbereich wird dazu entsprechend des Abstandes zwischen Schalhaut und der Öffnung im sphärischen Plattenbereich gewählt. Das Schraubenmutterelement kann also ähnlich einem Joystick auf der Kalottenplatte ausgelenkt werden.A locking device according to the invention for an anchor rod of an anchor system concrete wall formwork with a first and a second formwork element has a nut member for screwing through the anchor rod by a nut thread of the nut member. It is provided a dome plate, which can be fastened by means of fastening means on a rear side of one of the shuttering elements of the concrete wall formwork, so facing away from the concrete side facing skin surface usually longitudinal and / or cross bar side of the formwork element. The dome plate has a spherically shaped plate portion with an opening in which the nut member is arranged with radial play. The nut member has a groove-like radial circumferential receptacle in which the edges of the Opening are included in the spherical plate area. The radial clearance is circumferentially present, so that within the radial play a full deflection of the nut member on the dome plate is made possible. This results in a fulcrum of the preferably a dome nut comprehensive nut element in the region of the armature feedthrough bore in the formwork skin. The radius of the spherical plate area is chosen according to the distance between the formwork skin and the opening in the spherical plate area. The nut element can thus be deflected similar to a joystick on the dome plate.

Bei einer Verwendung der erfindungsgemäßen Arretiervorrichtung in einer Betonwandschalung, bei der sich die Schalungselemente und deshalb auch die Ankerdurchführungsbohrungen in den Schalhäuten nicht direkt fluchtend gegenüber stehen, werden auf die Schraubenmutterelemente einwirkende Druckkräfte trotz nicht senkrecht auf die Schalhautoberflächen stehenden Ankerstäben radial vollständig umlaufend flächig von der Kalottenoberfläche auf die Schraubenmutterelemente übertragen. Es wird derart ein stabilerer Aufbau der Betonwandschalung gewährleistet. Weiter werden mögliche Beschädigungen eines Ankersystems durch punktuelle Überlastung vermieden.When using the locking device according to the invention in a concrete wall formwork, in which the shuttering elements and therefore the Ankerdurchführungsbohrungen are not directly aligned in the Schalhäuten, acting on the nut elements compressive forces despite not perpendicular to the formwork surfaces anchor rods radially completely circumferential surface of the Kalottenoberfläche transferred to the nut elements. It is thus ensured a more stable construction of the concrete wall formwork. Next possible damage to an anchor system are avoided by selective overload.

Erfindungsgemäß ist am betonschalungsseitig anzuordnenden Ende des Schraubenmutterelements eine mit dem Schraubenmuttergewinde des Schraubenmutterelements fluchtende, rohrförmige Führungseinrichtung vorgesehen. Dadurch wird das Finden des Schraubenmuttergewindes, in das der Ankerstab eingeschraubt werden soll, mit dem Ankerstab wesentlich erleichtert. Die Innenoberfläche der rohrförmigen Führungseinrichtung kann dazu vorteilhaft trichterförmig ausgebildet sein. Zumindest jedoch übersteigt der Querschnitt der schraubenmutterelementabgewandten Öffnung der Führungseinrichtung den des Schraubenmuttergewindes des Schraubenmutterelements. Dabei endet die Führungseinrichtung im Bereich der Schalhautebene, so dass die Spitze eines Ankerstabes zwingend in die Öffnung der Führungseinrichtung beim Setzen eines Ankerstabes eintritt.In accordance with the invention, a tubular guiding device aligned with the screw nut thread of the screw nut element is provided on the end of the screw nut element to be arranged on the concrete formwork side. As a result, finding the nut thread, in which the anchor rod is to be screwed, with the anchor rod much easier. The inner surface of the tubular guide means may advantageously be funnel-shaped. However, at least the cross section of the screw nut element facing away from the opening of the guide device exceeds that of the nut thread of the nut member. In this case, the guide device ends in the region of the scarf skin level, so that the tip of an anchor rod compellingly enters the opening of the guide device when setting an anchor rod.

Besonders vorteilhaft ist am Schraubenmutterelement eine Verdrehsicherung vorgesehen. Diese Verdrehsicherung kann z.B. durch Ausbilden der aufeinander liegenden Oberflächen des Schraubenmutterelements und der Kalottenplatte mit einer hohen Verdrehreibung z.B. durch eine Noppenoberfläche erreicht werden. Bei Verwendung einer derartigen Arretiervorrichtung kann der Ankerstab, der z.B. von der Rückseite des ersten Schalungselements in die Arretiervorrichtung, die an der Rückseite des zweiten Schalungselements befestigt ist, eingeschraubt werden, ohne dass ein Schalungsbauer auf der Rückseite des zweiten Schalungselements die Arretiervorrichtung während des Einschraubens, zum Verhindern eines Mitdrehens des Schraubenmutterelements mit dem Ankerstab, bedienen muss. Eine derartige Arretiervorrichtung eignet sich also z.B. zum Einsatz an unzugänglichen Betonschalungsbereichen.Particularly advantageous is an anti-rotation is provided on the nut member. This anti-twist device can e.g. by forming the superposed surfaces of the nut member and the dome plate with a high twisting friction e.g. be achieved by a nubbed surface. When using such a locking device, the anchor rod, e.g. be screwed from the back of the first formwork element in the locking device, which is attached to the back of the second formwork element, without a formwork builder on the back of the second formwork element, the locking device during screwing, for preventing co-rotation of the nut member with the anchor rod operate got to. Such a locking device is therefore suitable e.g. For use on inaccessible concrete formwork areas.

Bevorzugt weist die Verdrehsicherung ein Anschlagelement auf, wobei durch das Anschlagelement eine Verdrehung des Schraubenmutterelements durch Anschlagen an einem, bevorzugt von den Befestigungsmitteln ausgebildeten, Anschlag verhinderbar ist. Dadurch ist ein besonders einfacher und sicherer Verdrehungsschutz gewährleistet. Ist das Anschlagelement flügelartig ausgebildet, so kann auch ein von dem Schraubenmutterelement weiter entfernt angeordneter Anschlag das Verdrehen verhindern.Preferably, the rotation on a stop element, wherein by the stop element, a rotation of the nut member by abutment on a, preferably formed by the fastening means, stop can be prevented. This ensures a particularly simple and secure anti-rotation protection. If the abutment element is of a wing-like design, a stop arranged further away from the nut element can also prevent twisting.

Ein erfindungsgemäßes Ankersystem einer Betonwandschalung umfasst einen Ankerstab und eine erste und eine zweite erfindungsgemäße Arretiervorrichtung, wobei der Ankerstab in die Schraubenmuttergewinde der Schraubenmutterelemente der Arretiervorrichtungen eingeschraubt ist. Bei Einsatz eines derartigen Ankersystems können die Vorteile der erfindungsgemäßen Arretiervorrichtung auf beiden Seiten der Betonwandschalung verwirklicht werden.An inventive anchoring system of a concrete wall formwork comprises an anchor rod and a first and a second locking device according to the invention, wherein the anchor rod in the nut screw thread the screw nut elements of the locking devices is screwed. When using such an anchor system, the advantages of the locking device according to the invention can be realized on both sides of the concrete wall formwork.

Bevorzugt weist der Ankerstab einen sich in Richtung einer Ankerstabspitze verjüngenden Verlauf auf, wobei ein erstes Schraubengewinde im ankerstabspitzenabgewandten Endbereich des Ankerstabes einen größeren Gewindedurchmesser als ein zweites Schraubengewinde im ankerstabspitzennahen Endbereich des Ankerstabes aufweist. Das ankerstabspitzennahe zweite Schraubengewinde kann so bis zum Anschlag in die zweite Arretiervorrichtung eingeschraubt werden, so dass sich eine definierte Lage des Ankerstabes und damit des zweiten Schalungselements ergibt.The anchor rod preferably has a course tapering in the direction of an anchor rod tip, wherein a first screw thread in the anchor rod tip end region of the anchor rod has a larger thread diameter than a second screw thread in the anchor rod near the anchor rod tip end. The ankerstabspitzennahe second screw thread can be screwed as far as the stop in the second locking device, so that there is a defined position of the anchor rod and thus the second formwork element.

Vorteilhaft verjüngt sich der Ankerstab zwischen dem ersten und dem zweiten Schraubengewinde konisch, was ein Entfernen des Ankerstabes nach Aushärten einer zwischen der Betonwandschalung ausgegossenen Betonwand erleichtert.Advantageously, the anchor rod tapers conically between the first and second screw threads, which facilitates removal of the anchor rod after curing of a concrete wall poured between the concrete wall formwork.

Bei einer erfindungsgemäßen Betonwandschalung ist mindestens ein erfindungsgemäßes Ankersystem appliziert. Dabei weist die Betonwandschalung ein erstes und ein zweites Schalungselement auf, wobei sich die Schalungselemente mit ihren Schalhäuten gegenüberstehen. Auf der Rückseite des ersten Schalungselements ist die erste Arretiervorrichtung des Ankersystems, bevorzugt mittels ersten Befestigungsmitteln befestigt, angeordnet und die zweite Arretiervorrichtung des Ankersystems ist an der Rückseite des zweiten Schalungselements, bevorzugt mittels zweiten Befestigungsmitteln befestigt, angeordnet. Der Ankerstab des Ankersystems ist von der Rückseite des ersten Schalungselements kommend, durch das Schraubenmuttergewinde des Schraubenmutterelements des ersten Arretierelements durchgeschraubt und durch jeweils eine Ankerdurchführungsbohrung in den Schalhäuten durchgeführt, in das Schraubenmuttergewinde des Schraubenmutterelements der zweiten Arretiervorrichtung eingeschraubt. Die Applikation des erfindungsgemäßen Ankersystems kann vorteilhaft derart vorgenommen werden, dass zunächst die zweite Arretiervorrichtung auf der Rückseite des zweiten Schalungselements, z.B. mittels eines Schraubbolzens befestigt wird. Dann wird der Ankerstab, auf den die erste Arretiervorrichtung bereits im Bereich des ankerstabspitzenfernen Endes aufgeschraubt ist, von der Rückseite des ersten Schalungselements aus durch die Schalungselemente hindurchgeführt und in das Schraubenmutterelement der zweiten Arretiervorrichtung auf Anschlag eingeschraubt. Danach wird die erste Arretiervorrichtung an dem angrenzenden Schalelement befestigt. Die Befestigung der beiden Arretiervorrichtungen an den Rückseiten der Schalungselemente dient, neben deren exakter Positionierung, auch dazu, dass vom Ankersystem auch beim Ausgießen der Betonwandschalung auf die Schalungselemente wirkende Druckkräfte auf den Ankerstab abgeleitet werden können.In a concrete wall formwork according to the invention, at least one anchor system according to the invention is applied. In this case, the concrete wall formwork on a first and a second formwork element, wherein facing the formwork elements with their formwork skins. On the back of the first formwork element, the first locking device of the anchor system, preferably fixed by means of first fastening means, arranged and the second Locking device of the anchor system is on the back of the second formwork element, preferably fixed by means of second fastening means arranged. The anchor rod of the anchor system is coming from the back of the first formwork element, screwed through the nut thread of the nut member of the first locking element and performed by a respective Ankerdurchführungsbohrung in Schalhäuten, screwed into the nut thread of the nut member of the second locking device. The application of the anchor system according to the invention can advantageously be made such that first the second locking device on the back of the second formwork element, for example by means of a screw bolt is attached. Then, the anchor rod on which the first locking device is already screwed in the region of the ankerstabspitzenfernen end, passed from the back of the first formwork element through the formwork elements and screwed into the nut element of the second locking device to stop. Thereafter, the first locking device is attached to the adjacent formwork element. The attachment of the two locking devices on the backs of the formwork elements is, in addition to the exact positioning, also to the fact that the anchor system can be derived on the anchor rod and the pouring of the concrete wall formwork acting on the formwork elements pressure forces.

Wenn als zweite Arretiervorrichtung eine Arretiervorrichtung mit einer rohrförmigen Führungseinrichtung und/oder einer Verdrehsicherung eingesetzt ist, wird das Finden des Schraubenmuttergewindes der zweiten Arretiervorrichtung vereinfacht und/oder die zweite Arretiervorrichtung muss nicht von einem Schalungsbauer festgehalten werden, um ein Mitdrehen beim Einschrauben des Ankerstabes zu verhindern.If a locking device with a tubular guide device and / or an anti-twist device is used as the second locking device, the finding of the nut thread of the second Locking simplified and / or the second locking device must not be held by a formwork builder to prevent co-rotation when screwing the anchor rod.

Sehr vorteilhaft wird bei einer erfindungsgemäßen Betonwandschalung als Ankersystem ein Ankersystem, bei dem ein erstes Schraubengewinde im ankerstabspitzenabgewandten Endbereich des Ankerstabes einen größeren Gewindedurchmesser als ein zweites Schraubengewinde im ankerstabspitzennahen Endbereich des Ankerstabes aufweist, bevorzugt mit einem sich konisch verjüngenden Ankerstab, eingesetzt. Wenn das zweite Schraubengewinde des Ankerstabes des Ankersystems auf Anschlag vollständig in das Schraubenmutterelement der zweiten Arretiervorrichtung des Ankersystems eingeschraubt ist und das Schraubenmutterelement der ersten Arretiervorrichtung des Ankersystems mittels eines durch ein Splintloch im Ankerstab durchgeführten Sicherungssplintes gesichert ist, kann die Wandstärke der zu betonierenden Wand ohne zusätzlichen Ausrichtungsaufwand, einfach durch abschließende Montage des Ankersystems exakt eingestellt werden.Very advantageous in a concrete wall formwork according to the invention as anchor system is an anchor system in which a first screw thread in ankerstabspitzenabgewandten end portion of the anchor rod has a larger thread diameter than a second screw thread in ankerstabspitzennahen end of the anchor rod, preferably with a conically tapered anchor rod used. When the second screw thread of the anchor rod of the anchor system is completely screwed into abutment in the nut member of the second locking device of the anchor system and the nut member of the first locking device of the anchor system is secured by means of a split pin in the anchor rod Sicherungssplintes, the wall thickness of the wall to be concreted without additional Alignment effort, simply adjusted by final assembly of the anchor system exactly.

Eine weitere erfindungsgemäße Ausgestaltung der Arretiervorrichtungen zur Befestigung an dem zuerst aufzustellenden Schalungselement könnte darin bestehen, dass die Arretiervorrichtung permanent an den Schalungselementen befestigt sind. Dies hätte den Vorteil, dass man am zuerst aufgestellten Schalungslement keine Vormontierung vornehmen muss. Die Arretierungsmittel müssten dann jedoch verschieblich an den Schalungselementen angebracht sein, damit man den Ankerstab mit der daran aufgeschraubten Arretiervorrichtung auf der Schließschalungsseite befestigen kann.Another embodiment of the locking devices according to the invention for attachment to the formwork element to be erected first could consist in that the locking device are permanently attached to the formwork elements. This would have the advantage that you have to make at the first established Schalungslement no Vormontierung. However, the locking means would then be slidably attached to the formwork elements, so that the anchor rod with the attached thereto locking device can attach to the closing formwork side.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen näher erläutert.The invention will be explained in more detail using an exemplary embodiment with reference to the drawings.

Die Figuren 1 bis 4 zeigen jeweils eine Ausführungsform einer erfindungsgemäßen Betonwandschalung in verschiedenen Phasen der Durchführung eines Ankerstabes eines erfindungsgemäßen Ankersystems in einem Schnitt durch das jeweilige erfindungsgemäße Ankersystem. Die Figuren 1b und 1c zeigen jeweils eine vergrößerte Darstellung aus Figur 1a.The FIGS. 1 to 4 each show an embodiment of a concrete wall formwork according to the invention in different phases of the implementation of an anchor rod of an anchor system according to the invention in a section through the respective anchor system according to the invention. The Figures 1b and 1c each show an enlarged view FIG. 1a ,

Die Figuren der Zeichnungen zeigen den erfindungsgemäßen Gegenstand stark schematisiert und sind nicht maßstäblich zu verstehen. Die einzelnen Bestandteile des erfindungsgemäßen Gegenstandes sind so dargestellt, dass ihr Aufbau gut gezeigt werden kann.The figures of the drawings show the subject matter of the invention in a highly schematic manner and are not to scale. The individual components of the article according to the invention are shown so that their structure can be well shown.

In den Figuren 1 bis 4 ist jeweils eine Ausführungsform einer erfindungsgemäßen Betonwandschalung in verschiedenen Phasen der Durchführung eines Ankerstabes 2 eines erfindungsgemäßen Ankersystems in einem Schnitt durch das jeweilige erfindungsgemäße Ankersystem gezeigt. Dargestellt ist jeweils ein erstes und ein zweites Schalungselement 5,6. Die Schalungselemente 5,6 weisen jeweils eine Schalhaut 7 sowie Längs- und Querriegel 9 auf, auf die die Schalhaut 7 üblicherweise aufgenietet ist. Die geschnittene Darstellung verläuft jeweils durch einen Längsriegel, so dass der jeweilige Längsriegel lediglich durch die Wandung 11 des Stahlprofils, aus dem dieser hergestellt ist, dargestellt ist. Die Schalungselemente 5,6 stehen sich zur Ausformung einer zu betonierenden Betonwand mit ihren Schalhäuten 7 gegenüber. Im Bereich jeweils eines Querriegels ist in den Schalhäuten 7 jeweils eine Ankerdurchführungsbohrung 13 vorgesehen. Der Ankerstab 2 ist oder wird gerade von der Rückseite des ersten Schalungselements 5 aus durch die Ankerdurchführungsbohrungen 13 und die Querriegel, in deren Bereich die Ankerdurchführungsbohrungen 13 angeordnet sind, hindurchgeführt. Dabei sind in den Ankerdurchführungsbohrungen 13 Dichtungen 15 angeordnet, die den Ankerstab 2 jeweils derart umgreifen, dass beim Betonieren im Wesentlichen keine Flüssigkeit durch die Ankerdurchführungsbohrungen 13 austreten kann. Auf der Rückseite der Schalungselemente 5,6 ist jeweils eine erfindungsgemäße Arretiervorrichtung 20,21 im Bereich der Ankerdurchführungsbohrungen 13 positioniert. Die Arretiervorrichtungen 20,21 weisen jeweils ein Schraubenmutterelement 23,24 mit einem Schraubenmuttergewinde, d.h. eine Bohrung mit einem Innengewinde, auf, durch das der Ankerstab 2 durchgeschraubt ist oder wird. Weiter weisen die Arretiervorrichtungen 20,21 jeweils eine Kalottenplatte 26,27 mit Befestigungsmitteln 30 zur Befestigung der Kalottenplatte 26,27 und damit der Arretiervorrichtung 20,21 an der Rückseite jeweils eines der Schalungselemente 5,6 auf. Die Befestigungsmittel 30 sind durch eine Bohrung im Randbereich der Kalottenplatte 26,27, ausgebildet durch die ein Schraubbolzen 32 in ein Schraubloch 34 am jeweiligen Längsriegel eingeschraubt werden kann oder eingeschraubt ist. Als technisch gleichwertige Befestigungsmittel 30 sind auch Klammern, Bajonette-Verschlüsse und ähnliche Haltemittel vorstellbar. Die Kalottenplatte 26,27 ist aus einer Stahlplatte gefertigt. Sie weist einen sphärisch ausgebildeten Plattenbereich, d.h. einen als Kugelschalenbereich ausgeformten Plattenbereich auf, in dem eine Öffnung vorgesehen ist. Die konkave Oberfläche der Kalottenplatte 26,27 ist in Richtung der Schalhaut 7 des jeweiligen Schalungselements 5,6 mit umlaufend radialem Spiel angeordnet. In der Öffnung ist das Schraubenmutterelement 23,24 der jeweiligen Arretiervorrichtung 20,21 positioniert. An den Schraubenmutterelementen 23,24 ist jeweils eine radial umlaufende Nut vorgesehen, die eine Aufnahme 40 ausbildet, in der die Ränder der Öffnung im sphärischen Plattenbereich der zugehörigen Kalottenplatte 26,27 aufgenommen sind. Die Aufnahme 40 hat eine dem sphärischen Plattenbereich entsprechende Ausformung, so dass innerhalb des radialen Spiels eine vollumfängliche Auslenkung des Schraubenmutterelements 23,24 auf der Kalottenplatte 26,27, von der Kalottenplatte 26,27 geführt, ermöglicht ist. Die Nut kann z.B. dadurch ausgebildet werden, dass ein die betonschalungsseitige Wand der Nut ausbildender Ring 41 auf einen rohrförmigen Bereich eines als Kalottenmutter 42 ausgeformten Teils des Schraubenmutterelements 23,24 aufgesteckt oder aufgeschraubt ist. An der jeweils am zweiten Schalungselement 6 positionierten erfindungsgemäßen Arretiervorrichtung 21 ist am betonschalungsseitig angeordneten Ende des Schraubenmutterelements 24 eine mit dem Schraubenmuttergewinde des Schraubenmutterelements 24 fluchtende, rohrförmige Führungseinrichtung 45 vorgesehen (z.B. hülsenartiger Fortsatz, der am Schraubenmutterelement 24 ausgebildet ist), die einen konisch verlaufenden freien Querschnitt aufweist. Die Innenoberfläche dieser Führungseinrichtung 45 ist mit einem Öffnungswinkel trichterartig ausgeformt, so dass sie als Führung beim Einführen eines Ankerstabes 2, wie in Figur 2 dargestellt, dient. Die Öffnung der Führungseinrichtung 45 reicht in etwa bis zu der Dichtung 15 in den zugehörigen Ankerdurchführungsbohrungen 13 der entsprechenden Schalhaut 7, so dass ein Ankerstab 2, der durch die zugehörige Dichtung 15 mit dessen Spitze 50 hindurchgeführt wird, unmittelbar in die Führungseinrichtung 45 eingeführt wird, die einstückig an die Kalottenmutter 42 angeformt ist. Somit liegt der Drehpunkt (Kreismittelpunkt) um die sich die Kalottenmutter 42 beim Einschieben eines Ankerstabes 2 verschwenken, auslenken bzw. verschieben lässt im Bereich der Ebene der Schalhaut 7. Weiter ist an den Schraubenmutterelementen 23,24 der Arretiervorrichtungen 20,21, die an den Rückseiten der zweiten Schalungselemente 6, also jener Schalungselemente 6, durch die die Ankerstäbe 2 von der Vorderseite aus, also von der Schalhaut 7 aus, eingeführt werden, jeweils eine Verdrehsicherung 60 vorgesehen. Diese Verdrehsicherungen 60 sind derart ausgebildet, dass ein Außenbereich der Schraubenmutterelemente 24 beim Verdrehen des jeweiligen Schraubenmutterelements 24 an einen, z.B. von den Befestigungsmitteln 30 der zugehörigen Kalottenplatte 27 gebildeten Anschlag anstoßen, so dass sich das Schraubenmutterelement 21 nicht weiter verdrehen kann. Die Schalungselemente 5,6 der Betonwandschalung in den Figuren 1 sind mit ihren Ankerdurchführungsbohrungen 13 fluchtend gegenüberliegend angeordnet. Daraus folgt, dass die Schraubenmutterelemente 23,24 in den zugehörigen Öffnungen in den Kalottenplatten 26,27 zentrisch positioniert sind. Der Ankerstab 2 ist in Figur 1 vollständig eingeschraubt. Dazu weist das Schraubengewinde 70 des Ankerstabes 2 im Bereich der Spitze 50 des Ankerstabes 2 einen geringeren Durchmesser als der restliche Ankerstab 2 auf, wodurch am Übergang des Schraubengewindes 70 zum restlichen Ankerstab 2 ein Anschlag gebildet wird. Die Einschraubtiefe des Schraubengewindes 70 im Bereich der Spitze 50 des Ankerstabes 2 in das Schraubenmutterelement 24 der zugehörigen Arretiervorrichtung 21 ist damit definiert vorgegeben. Der Durchmesser des Schraubengewindes 71 im Bereich des ankerspitzenabgewandten Endes des Ankerstabes 2 ist daher größer als der Durchmesser des Schraubengewindes 70 im Bereich der Spitze 50 des Ankerstabes 2. Weiter folgt daraus, dass das Schraubenmuttergewinde der an der Rückseite des ersten Schalungselements 5 positionierten Arretiervorrichtung 20, von der aus der Ankerstab 2 eingeführt wird, einen größeren Durchmesser hat als das Schraubenmuttergewinde der Arretiervorrichtung 21 auf der Rückseite des zweiten Schalungselements 6. Die dargestellten Ankerstäbe 2 weisen ferner an deren von der Spitze 50 des jeweiligen Ankerstabes abgewandten Endbereichen, auf die die an der Rückseite des ersten Schalungselements 5 befestigten Arretiervorrichtungen 20 aufgeschraubt sind, Splintlöcher 75 zur Durchführung von Sicherungssplinten auf. Mittels der Anordnung dieser Splintlöcher 75 kann die Wandstärke der zu betonierenden Wand festgelegt werden. Um auch Druckkräfte auf die Schalungselemente 5,6, die zu einer Verringerung der Wandstärke der zu betonierenden Wand führen würden, durch das dargestellte Ankersystem aufnehmen zu können, wäre in Figur 1 noch eine Befestigung der Kalottenplatten 26,27 an den Rückseiten der Schalungselementen 5,6 notwendig. Letztere Befestigung ist in den Figuren 2 und 3 mittels Schraubbolzen 32 mit angeformten Ringen vorgenommen. Die Ankerstäbe 2 haben in deren zwischen den Schalhäuten 7 zu positionierenden Bereichen eine sich in Richtung der jeweiligen Ankerspitze 50 konisch verjüngende Ausformung, wodurch die Ankerstäbe 2, insbesondere wenn diese vor deren Applikation an der Betonwandschalung behandelt bzw. eingeölt wurden, nach Aushärten der betonierten Betonwand wieder erleichtert entfernbar sind. Die Schalungselemente 5,6 der Betonwandschalungen der Figuren 2 bis 4 sind mit ihren Ankerdurchführungsbohrungen 13 nicht fluchtend gegenüberliegend angeordnet. Dementsprechend sind die Schraubenmutterelemente der Arretiervorrichtungen 20,21 nicht zentriert in den Öffnungen der sphärischen Plattenbereiche der zugehörigen Kalottenplatten angeordnet. Die Schraubenmutterelemente sind vielmehr auf den Oberflächen der sphärischen Bereiche der Kalottenplatten von den zugehörigen Kalottenplatten geführt radial ausgelenkt, so dass die Ankerstäbe 2 nicht senkrecht zu den Schalhäuten 7 der Schalungselemente 5,6 ausgerichtet sind.In the FIGS. 1 to 4 In each case an embodiment of a concrete wall formwork according to the invention is shown in different phases of the implementation of an anchor rod 2 of an anchor system according to the invention in a section through the respective anchor system according to the invention. Shown is in each case a first and a second formwork element 5.6. The formwork elements 5.6 each have a formwork skin 7 and longitudinal and transverse bars 9, to which the formwork skin 7 is usually riveted. The cut representation runs in each case by a longitudinal bar, so that the respective longitudinal bar only by the wall 11 of the steel profile from which it is made, is shown. The formwork elements 5.6 are facing the formation of a concrete wall to be concreted with their Schalhäuten 7. In each case a cross bar is provided in the Schalhäuten 7 each have an anchor passage bore 13. The anchor rod 2 is or is just from the back of the first formwork element 5 through the anchor bushing holes 13 and the cross bar, in whose area the armature feedthrough holes 13 are arranged, passed. In this case, seals 15 are arranged in the armature feed-through bores 13, which surround the armature bar 2 in such a way that substantially no liquid can escape through the armature feed-through bores 13 during concreting. On the back of the formwork elements 5.6 respectively a locking device 20,21 according to the invention in the region of the armature feedthrough holes 13 is positioned. The locking devices 20,21 each have a nut member 23,24 with a nut thread, ie a bore with an internal thread, through which the anchor rod 2 is screwed through or is. Next, the locking devices 20,21 each have a dome plate 26,27 with fastening means 30 for fastening the dome plate 26,27 and thus the locking device 20,21 on the back of each one of the formwork elements 5.6. The fastening means 30 are formed by a hole in the edge region of the dome plate 26,27, formed by a screw bolt 32 can be screwed into a screw hole 34 on the respective longitudinal bolt or screwed. As a technically equivalent fastener 30 and brackets, bayonet locks and similar retaining means are conceivable. The dome plate 26,27 is made of a steel plate. she has a spherically shaped plate region, ie a plate region shaped as a spherical shell region, in which an opening is provided. The concave surface of the dome plate 26,27 is arranged in the direction of the formwork skin 7 of the respective formwork element 5,6 with circumferential radial play. In the opening, the nut member 23,24 of the respective locking device 20,21 is positioned. At the screw nut elements 23,24 each have a radially encircling groove is provided which forms a receptacle 40 in which the edges of the opening in the spherical plate portion of the associated dome plate 26,27 are accommodated. The receptacle 40 has a shape corresponding to the spherical plate area, so that within the radial play a full deflection of the nut member 23,24 on the dome plate 26,27, guided by the dome plate 26,27, is possible. The groove can be formed, for example, in that a ring 41 forming the concrete shutter side wall of the groove is slipped or screwed onto a tubular region of a part of the screw nut element 23, 24 which is formed as a dome nut 42. At the respectively on the second formwork element 6 positioned locking device 21 according to the invention is arranged on concrete shutter side end of the nut member 24 aligned with the nut thread of the nut member 24, tubular guide means 45 is provided (eg sleeve-like extension, which is formed on the nut member 24) having a conically extending free Cross section has. The inner surface of this guide device 45 is funnel-shaped with an opening angle, so that it serves as a guide during the insertion of an anchor rod 2, as in FIG. 2 represented, serves. The opening of the guide means 45 extends approximately to the seal 15 in the associated anchor bushing holes 13 of the corresponding formwork skin 7, so that an anchor rod 2, which is passed through the associated seal 15 with its tip 50, is inserted directly into the guide means 45, which is integrally formed on the cap nut 42. Thus, the pivot point (circle center) to which the cap nut 42 pivot when inserting an anchor rod 2, deflect or can be moved in the plane of the formwork skin 7. Next is on the nut members 23,24 of the locking devices 20,21, to the Rear sides of the second formwork elements 6, ie those formwork elements 6, by which the anchor rods 2 are introduced from the front side, ie from the formwork skin 7, in each case an anti-rotation device 60 is provided. These anti-rotation devices 60 are designed in such a manner that an outer region of the screw nut elements 24 abuts upon rotation of the respective screw nut element 24 against a stop formed, for example, by the attachment means 30 of the associated dome plate 27, so that the nut element 21 can not rotate any further. The formwork elements 5.6 of the concrete wall formwork in the FIGS. 1 are arranged with their armature feedthrough holes 13 aligned opposite one another. It follows that the nut elements 23,24 are centrally positioned in the associated openings in the dome plates 26,27. The anchor rod 2 is in FIG. 1 completely screwed in. For this purpose, the screw thread 70 of the anchor rod 2 in the region of the tip 50 of the anchor rod 2 has a smaller diameter than the remaining anchor rod 2, whereby at the transition of the screw thread 70 to the remaining anchor rod 2, a stop is formed. The screw-in depth of the screw thread 70 in the region of the tip 50 of the anchor rod 2 in the nut member 24 of the associated locking device 21 is defined so defined. The diameter of the screw thread 71 in the region of the ankerspitzenabgewandten end of the anchor rod 2 is therefore greater than the diameter of the screw thread 70 in the region of the tip 50 of the anchor rod 2. It also follows that the nut thread of the positioned at the back of the first shuttering element 5 locking device 20, from the anchor rod 2 is inserted, has a larger diameter than the nut thread of the locking device 21 on the back of the second formwork element 6. The illustrated anchor rods 2 also have at their remote from the tip 50 of the respective anchor rod end portions on which the at Rear side of the first shuttering element 5 fastened locking devices 20 are screwed on pinholes 75 for performing securing splints on. By means of the arrangement of these pinholes 75, the wall thickness of the wall to be concreted can be determined. In order to be able to absorb compressive forces on the formwork elements 5, 6, which would lead to a reduction in the wall thickness of the wall to be concreted, by the illustrated anchoring system, it would be apparent from FIGS FIG. 1 nor an attachment of the dome plates 26,27 on the backs of the formwork elements 5,6 necessary. The latter attachment is in the Figures 2 and 3 made by means of bolts 32 with molded rings. The anchor rods 2 have in their between the formwork skins 7 to be positioned areas in the direction of the respective armature tip 50 conically tapered shape, whereby the anchor rods 2, in particular if they have been treated or oiled prior to their application to the concrete wall formwork, can be removed once again in a facilitated manner after the concrete wall has hardened. The formwork elements 5.6 of the concrete wall formworks of FIGS. 2 to 4 are arranged with their anchor bushing holes 13 are not aligned opposite. Accordingly, the nut members of the locking devices 20, 21 are not centered in the openings of the spherical plate portions of the associated dome plates. The nut elements are rather guided on the surfaces of the spherical areas of the dome plates of the associated dome plates radially deflected so that the anchor rods 2 are not aligned perpendicular to the scarf skins 7 of the formwork elements 5.6.

In Figur 2 ist dargestellt, wie der Ankerstab 2, nach dem Durchführen durch die Ankerdurchführungsbohrung 13 des zweiten Schalungselements 6, mit dessen Spitze 50 in die rohrförmige Führungseinrichtung 45 der an der Rückseite des zweiten Schalungselements 6 befestigten Arretiervorrichtung 21 eindringt und von der Führungseinrichtung 45 zum Schraubenmuttergewinde des zugehörigen Schraubenmutterelements geführt wird.In FIG. 2 is shown as the anchor rod 2, after passing through the armature feedthrough bore 13 of the second formwork element 6, with the tip 50 penetrates into the tubular guide means 45 of the attached to the back of the second formwork element 6 locking device 21 and from the guide means 45 to the nut thread of the associated Nut element is guided.

In der Ausführungsform der an der Rückseite des zweiten Schalungselements 6 in Figur 4 angeordneten Arretiervorrichtung ist die Verdrehsicherung 60 als eine Art Flügel 80 vom Schraubenmutterelement abstehend ausgebildet, so dass auch ein weiter vom Schraubenmutterelement entfernter Anschlag ein Mitdrehen des Schraubenmutterelements beim Einschrauben des Ankerstabes 2 verhindern kann. Der Ankerstab 2 in Figur 4 weist ein durchgängiges Schraubengewinde entlang seiner gesamten Länge auf. Letzteres macht es notwendig, den Ankerstab 2 vor dessen Applikation an der Betonwandschalung zumindest in dem nachfolgend einbetonierten Bereich des Ankerstabes 2 mit einer konisch verlaufenden Kunststoffschicht 82 zu umhüllen, damit der Ankerstab nach dem Aushärten der Betonwand wieder entfernt werden kann.In the embodiment of the at the back of the second formwork element 6 in FIG. 4 arranged locking device, the anti-rotation device 60 is formed as a kind of wing 80 projecting from the nut member, so that a further remote from the nut member stop can prevent co-rotation of the nut member when screwing the anchor rod 2. The anchor rod 2 in FIG. 4 has a consistent Screw thread along its entire length. The latter makes it necessary to coat the anchor rod 2 before its application to the concrete wall formwork, at least in the subsequently concreted area of the anchor rod 2 with a conical plastic layer 82, so that the anchor rod after curing of the concrete wall can be removed again.
