Definitions

  • the invention relates to a method for assembling wall formwork and an anchor system for carrying out the method.
  • a wall formwork comprises a formwork skin on the front side and elements such as longitudinal beams, crossbars and frames that support the formwork skin on the rear side.
  • the elements supporting the formwork skin are firmly connected to the formwork skin, for example by means of screws, grooves or nails.
  • a longitudinal beam extends in the vertical direction and a crossbar in the horizontal direction.
  • the two sides of a wall to be concreted are bounded by wall formwork.
  • the front of each wall formwork then adjoins the concrete with its formwork skin.
  • Opposite wall formwork according to the invention are generally held in place by a plurality of anchor systems according to the invention.
  • the anchor rods of the anchor systems are inserted through openings in the wall formwork and attached at their ends to the elements supporting the respective formwork skin by means of locking devices so that at least the tensile force acting on the anchor rods during concreting is absorbed.
  • These openings leading through the wall formwork are also called anchor rod bores.
  • a set formwork is a wall formwork that is set up first.
  • the closing formwork is then set up opposite the setting formwork.
  • Setting formwork and closing formwork are connected to one another during assembly using one or more anchor systems. Concrete is poured into the space between the formwork and the closing formwork. Subsequent hardening of the concrete creates a wall.
  • an anchor rod usually one or both ends of an anchor rod have a thread onto which, for example, screw nuts are screwed as anchor fixings.
  • the maximum effective length of the anchor rod and thus the strength (thickness) of the wall to be concreted is therefore regularly determined by the length of the central anchor rod area.
  • the pressure exerted by the liquid concrete on the formlining during concreting is diverted onto the tie rods.
  • the anchor rods are put under tension.
  • spacers can be inserted into the volume of the wall to be concreted, which can absorb the compressive forces generated during concreting, thereby ensuring that these compressive forces do not undesirably affect the wall thickness, i.e. reduce it.
  • Sleeves can serve as spacers.
  • locking devices of anchor systems can be attached to the wall formwork so that anchor rods can also absorb compressive forces.
  • each anchor rod is released by at least one locking device and pulled out of the concrete wall. If necessary, the upper side of a closing formwork is hooked onto a hook of a crane, for example, so that it does not fall over as soon as all anchor rods have been pulled out. If a sleeve has been used, the sleeve remains at least partially in the concrete.
  • the wall formwork is finally moved in a suitable manner in order to produce a next wall or a next wall section. If the wall formwork has been moved, the anchor systems are mounted or attached to the wall formwork again.
  • an anchor system with two locking devices and an anchor rod for a wall formwork with a first and a second formwork element is known.
  • the anchor rod has a thread at each of its two ends which are screwed into screw nut elements of the locking devices.
  • Each locking device comprises a spherical plate which is fastened to a rear side of a wall formwork by means of fastening means.
  • the anchor system can therefore absorb both tensile and compressive forces from a wall formwork.
  • the present invention relates to the case that the anchor system comprises a sleeve which remains at least partially in the hardened concrete after the anchor rod has been pulled out.
  • the installation of wall formwork should be possible in a simple and reliable manner.
  • a system is to be provided which enables the method to be carried out.
  • Claim 1 relates to a method for assembling two wall formwork. This includes the following steps: A first locking device has been attached to the rear of one of the wall formwork before this wall formwork is erected. This can be done with the help of screws or clamping means. Fastened means that the locking device is firmly and thus securely connected to the wall formwork. The locking device can, however, in principle be released again from the wall formwork with the aid of a tool.
  • the fastening or fixed connection therefore basically comprises fastening means such as screws or clamping means that enable fastening and loosening. This makes it possible to first select a suitable fastening location on the back of the wall formwork before erecting a wall formwork.
  • Supporting elements are sufficiently stable and basically consist of metal, so that they are particularly suitable.
  • Supporting elements of a wall formwork are permanently connected to the formwork skin during assembly and disassembly.
  • a formwork skin can be connected to the supporting elements by means of screws, for example. Detaching the formlining from the supporting elements is only intended for repair purposes. A detachment of the formlining from the supporting elements is neither intended nor necessary in the context of an assembly and disassembly of wall formwork for the production of walls.
  • the first locking device has a pipe section which, in the fastened state mentioned, extends into a first wall formwork.
  • the first locking device can be made up of one or more parts.
  • the pipe section can protrude vertically from a disc with a hole. The pipe section then opens into the hole in the disc. The disc can be detached from the rest of the locking device, that is to say a separate part
  • the disk can also be connected captively to the rest of the locking device.
  • the pipe section extends in particular at least as far as the outside of the formwork facing and then closes up with the formwork facing flush with the outside of the wall formwork or protrudes slightly from the formwork facing.
  • the outer diameter of the pipe section is at least slightly smaller in the case of the formwork skin than the inner diameter of the anchor rod bore in the case of the formwork skin.
  • a small gap therefore remains between the pipe section and the anchor rod bore in the formwork, which is in particular smaller than 5 mm or 3 mm, preferably smaller than 2 mm, particularly preferably smaller than 1 mm, when the first locking device is attached to the wall formwork.
  • the two wall formworks are set up opposite one another, as already described at the beginning.
  • An anchor rod is partially encased by a slidably arranged sleeve.
  • the surface of the sleeve is preferably smooth or at least approximately smooth. Since the anchor rod can only be partially enveloped by the sleeve, the sleeve is shorter than the anchor rod. Otherwise it would be possible for the sleeve to completely envelop the anchor rod.
  • the anchor rod is pushed through anchor rod bores in the two wall formwork in such a way that finally one end of the sleeve rests against the end of the pipe section which extends into the first wall formwork. A connection with a sealing effect is thus created between said end of the sleeve and said end of the pipe section of the first locking device.
  • the end of the anchor rod pushed through is firmly connected to the first locking device with the aid of fastening means, that is to say is fastened to the first locking device, for example by means of a form fit.
  • the end of the anchor rod pushed through can have a thread as a fastening means, which thread is screwed into an internal thread of the locking device serving as a fastening means.
  • a bayonet connection or something similar can also be provided, for example, which enables the end of the anchor rod pushed through to be fastened to the first locking device.
  • the end of the anchor rod that is not pushed through is firmly connected to a second locking device by fastening means, so that a pipe section of the second locking device extends into the wall formwork and adjoins the sleeve in a sealing manner.
  • the pipe section of the second locking device is also preferably dimensioned in the same way as the pipe section of the first locking device. In the assembled state, it is therefore preferably flush with the outside of the second formwork or extends beyond this outside. Then again preferably only a small gap remains between the formwork facing and the pipe section in order to avoid, in an improved manner, that during the production of a wall concrete flows into the second wall formwork.
  • the fastening means can be such that the second locking device can be firmly connected to the end of the anchor rod that is not pushed through by a form fit.
  • the end of the anchor rod that is not pushed through can have a thread which can be screwed to an internal thread of the second locking device in order to firmly connect the end of the anchor rod that is not pushed through to the second locking device.
  • Other fastening means such as bayonet connections are also possible. If the first and second locking devices have been firmly connected to the anchor rod ends, the two wall formwork can no longer be detached from one another.
  • the outer diameter of the sleeve corresponds to the outer diameter of the pipe sections of the locking devices so that one end of a sleeve can adjoin one end of a pipe section in a sealing manner.
  • the adjoining prevents concrete from flowing unplanned to the tie rod during the construction of a wall.
  • the inner diameter of the sleeve and the pipe sections are selected so that the anchor rod can be pushed through the sleeve and the pipe sections. There then remains a small amount of play, i.e. only a very small gap, between the sleeve and the anchor rod and between the pipe sections and the anchor rod.
  • This gap is preferably a maximum of 5 mm, more preferably a maximum of 4, 3 or 2 mm.
  • an anchor rod By providing a sleeve, an anchor rod can be pulled out particularly easily after the concrete has hardened.
  • the method makes it possible to assemble from only one side of a wall formwork. Since the sleeve, together with the anchor rod, can be inserted through an anchor rod bore during assembly and consequently pushed through it, it is quick and easy
  • the sleeve consists of a tube made of plastic and two end pieces, each end piece being detachably connected to one end of the tube.
  • each end piece is partially inserted into the pipe and thus connected to the pipe.
  • the end pieces are then preferably held in a clamping manner by the pipe, so that there is a fixed but releasable connection between the end pieces and the pipe.
  • the sleeve is preferably made entirely of plastic.
  • the pipe made of plastic can advantageously be obtained on a construction site by cutting an endless pipe to length without having to cut exactly perpendicular to the longitudinal axis of the pipe.
  • An end face of the pipe does not have to run exactly perpendicular to the longitudinal axis of the pipe in order to avoid sealing problems in the assembled state.
  • the end pieces ensure that a suitable, tight connection between the sleeve and the aforementioned tubular pieces of the locking devices is possible, even if the length was not ideally cut.
  • the provision of end pieces also makes it possible to compensate for a pipe length that is too short. If the pipe is too short, the end pieces are not inserted into the pipe as much as possible in order to compensate for the deficiency. After being inserted, a region of the end piece protrudes from the end of the cut-to-length tube in order to form an end of the sleeve which can lie tightly against a tube piece of a locking device.
  • An anchor system which comprises an anchor rod, a sleeve and two locking devices, is used to carry out the method.
  • Each locking device can be fixedly connected to one end of the anchor rod with the aid of fastening means which, for example, can comprise threads for fastening.

Description

Die Erfindung betrifft ein Verfahren für eine Montage von Wandschalungen sowie ein Ankersystem zur Durchführung des Verfahrens.The invention relates to a method for assembling wall formwork and an anchor system for carrying out the method.

Ein Ankersystem im Sinne der vorliegenden Erfindung wird in der Schalungstechnik beim Betonieren von Stahlbetonbauten eingesetzt, um Wandschalungen zu montieren. Eine erfindungsgemäße Wandschalung umfasst auf der Vorderseite eine Schalhaut und auf der Rückseite die Schalhaut stützende Elemente wie Längsträger, Querriegel und Rahmen. Die Schalhaut stützenden Elemente sind mit der Schalhaut fest verbunden, beispielsweise mittels Schrauben, Nuten oder Nägeln. Im aufgestellten Zustand einer Wandschalung erstrecken sich ein Längsträger in vertikaler Richtung und ein Querriegel in horizontaler Richtung.An anchor system within the meaning of the present invention is used in formwork technology when concreting reinforced concrete structures in order to assemble wall formwork. A wall formwork according to the invention comprises a formwork skin on the front side and elements such as longitudinal beams, crossbars and frames that support the formwork skin on the rear side. The elements supporting the formwork skin are firmly connected to the formwork skin, for example by means of screws, grooves or nails. In the erected state of a wall formwork, a longitudinal beam extends in the vertical direction and a crossbar in the horizontal direction.

Die beiden Seiten einer zu betonierenden Wand werden durch Wandschalungen begrenzt. Die Vorderseite einer jeden Wandschalung grenzt dann mit ihrer Schalhaut an den Beton an. Sich gegenüberliegende erfindungsgemäße Wandschalungen werden in der Regeldurch eine Mehrzahl von erfindungsgemäßen Ankersystemen gehalten. Die Ankerstäbe der Ankersysteme werden durch Öffnungen in den Wandschalungen hindurch gesteckt und an ihren Enden an den die jeweilige Schalhaut stützenden Elementen erfindungsgemäß mittels Arretiervorrichtungen so befestigt, dass zumindest die beim Betonieren auf die Ankerstäbe wirkende Zugkraft aufgenommen wird. Diese durch die Wandschalungen hindurchführenden Öffnungen werden auch Ankerstabbohrungen genannt.The two sides of a wall to be concreted are bounded by wall formwork. The front of each wall formwork then adjoins the concrete with its formwork skin. Opposite wall formwork according to the invention are generally held in place by a plurality of anchor systems according to the invention. The anchor rods of the anchor systems are inserted through openings in the wall formwork and attached at their ends to the elements supporting the respective formwork skin by means of locking devices so that at least the tensile force acting on the anchor rods during concreting is absorbed. These openings leading through the wall formwork are also called anchor rod bores.

In der Schalungstechnik wird zwischen einer Stellschalung und einer Schließschalung unterschieden. Eine Stellschalung ist eine Wandschalung, die zuerst aufgestellt wird. Im Anschluss daran wird der Stellschalung gegenüberliegend die Schließschalung aufgestellt. Stellschalung und Schließschalung werden im Rahmen der Montage durch ein oder mehrere Ankersysteme miteinander verbunden. In den Zwischenraum zwischen Stellschalung und Schließschalung wird Beton hinein gegossen. Durch anschließendes Aushärten des Betons entsteht eine Wand.In formwork technology, a distinction is made between setting formwork and closing formwork. A set formwork is a wall formwork that is set up first. The closing formwork is then set up opposite the setting formwork. Setting formwork and closing formwork are connected to one another during assembly using one or more anchor systems. Concrete is poured into the space between the formwork and the closing formwork. Subsequent hardening of the concrete creates a wall.

Üblicherweise weisen ein oder die beiden Enden eines Ankerstabs ein Gewinde auf, auf welche zum Beispiel Schraubenmuttern als Ankerfixierungen aufgeschraubt werden. Der mittlere Bereich eines solchen Ankerstabes, an den während des Betonierens Beton angrenzen kann, weist vorteilhaft eine glatte Oberfläche auf oder wird zumindest während des Betonierens von einer Hülse umhüllt. Andernfalls würde ein Gewinde eines Ankerstabs einbetoniert. Der Ankerstab könnte dann nicht mehr unproblematisch aus dem ausgehärteten Beton herausgezogen werden.Usually one or both ends of an anchor rod have a thread onto which, for example, screw nuts are screwed as anchor fixings. The central area of such an anchor rod, which concrete can adjoin during concreting, advantageously has a smooth surface or is at least encased by a sleeve during concreting. Otherwise a thread of an anchor rod would be concreted in. The anchor rod could then no longer be pulled out of the hardened concrete without problems.

Die maximal wirksame Länge des Ankerstabs und damit die Stärke (Dicke) der zu betonierenden Wand wird daher regelmäßig durch die Länge des mittleren Ankerstabbereichs festgelegt. Gleichzeitig wird der beim Betonieren vom flüssigen Beton auf die Schalhaut ausgeübte Druck auf die Ankerstäbe abgeleitet. Die Ankerstäbe werden dabei auf Zug belastet.The maximum effective length of the anchor rod and thus the strength (thickness) of the wall to be concreted is therefore regularly determined by the length of the central anchor rod area. At the same time, the pressure exerted by the liquid concrete on the formlining during concreting is diverted onto the tie rods. The anchor rods are put under tension.

Zwischen den Schalhäuten können Abstandshalter in das Volumen der zu betonierenden Wand eingebracht werden, welche die beim Betonieren entstehenden Druckkräfte aufnehmen können, wodurch sichergestellt wird, dass diese Druckkräfte die Wandstärke nicht unerwünscht beeinflussen, d.h. vermindern. Hülsen können als Abstandshalter dienen. Alternativ oder ergänzend können Arretiervorrichtungen von Ankersystemen an den Wandschalungen befestigt werden, damit Ankerstäbe auch Druckkräfte aufnehmen können.Between the formwork skins, spacers can be inserted into the volume of the wall to be concreted, which can absorb the compressive forces generated during concreting, thereby ensuring that these compressive forces do not undesirably affect the wall thickness, i.e. reduce it. Sleeves can serve as spacers. Alternatively or in addition, locking devices of anchor systems can be attached to the wall formwork so that anchor rods can also absorb compressive forces.

Ist der zwischen zwei Wandschalungen gegossene Beton ausgehärtet, so wird ein jeder Ankerstab von zumindest einer Arretiervorrichtung gelöst und aus der Betonwand herausgezogen. Erforderlichenfalls wird zuvor die Oberseite einer Schließschalung zum Beispiel an einem Haken eines Krans eingehängt, damit diese nicht umfällt, sobald sämtliche Ankerstäbe herausgezogen worden sind. Wurde eine Hülse eingesetzt, so verbleibt die Hülse zumindest teilweise im Beton.If the concrete poured between two wall formwork has hardened, each anchor rod is released by at least one locking device and pulled out of the concrete wall. If necessary, the upper side of a closing formwork is hooked onto a hook of a crane, for example, so that it does not fall over as soon as all anchor rods have been pulled out. If a sleeve has been used, the sleeve remains at least partially in the concrete.

Zum Beispiel mit Hilfe des Krans werden die Wandschalungen schließlich geeignet versetzt, um eine nächste Wand oder einen nächsten Wandabschnitt herzustellen. Sind die Wandschalungen versetzt worden, dann werden die Ankersysteme wieder an den Wandschalungen montiert bzw. angebracht.With the aid of the crane, for example, the wall formwork is finally moved in a suitable manner in order to produce a next wall or a next wall section. If the wall formwork has been moved, the anchor systems are mounted or attached to the wall formwork again.

Aus der Druckschrift WO 2008/089737 A1 ist ein Ankersystem mit zwei Arretiervorrichtungen und einem Ankerstab für eine Wandschalung mit einem ersten und einem zweiten Schalungselement bekannt. Der Ankerstab weist an seinen beiden Enden jeweils ein Gewinde auf, die in Schraubenmutterelemente der Arretiervorrichtungen hineingeschraubt werden. Eine jede Arretiervorrichtung umfasst eine Kalottenplatte, die mittels Befestigungsmitteln an einer Rückseite einer Wandschalung befestigt wird. Das Ankersystem kann daher sowohl Zug- als auch Druckkräfte einer Wandschalung aufnehmen.From the pamphlet WO 2008/089737 A1 an anchor system with two locking devices and an anchor rod for a wall formwork with a first and a second formwork element is known. The anchor rod has a thread at each of its two ends which are screwed into screw nut elements of the locking devices. Each locking device comprises a spherical plate which is fastened to a rear side of a wall formwork by means of fastening means. The anchor system can therefore absorb both tensile and compressive forces from a wall formwork.

Aus der WO 2014/012685 A1 ist bekannt, eine Arretiervorrichtung zunächst auf der Rückseite einer Schalung zu befestigen. Dies kann bereits vor dem Aufstellen der Schalungen geschehen sein. Von der anderen Schalung aus wird im aufgestellten Zustand dann der Ankerstab durch die Ankerstabbohrungen hindurch geschoben und mit der bereits befestigten Arretiervorrichtung verbunden. Für ein solches Montageverfahren genügt ein Monteur, ohne dass der Monteur während der Montage zwischen den beiden Seiten der aufgestellten Schalungen hin und her wechseln müsste.From the WO 2014/012685 A1 it is known to first attach a locking device to the back of a formwork. This can be done before the formwork is set up. From the other formwork, in the erected state, the anchor rod is then pushed through the anchor rod holes and connected to the locking device that has already been attached. One fitter is sufficient for such an assembly process, without the fitter having to switch back and forth between the two sides of the erected formwork during assembly.

Aus den Druckschriften EP 1 541 781 A1 und DE 34 05 976 A1 sind Verfahren zum Montieren von Wandschalungen, sowie Ankersysteme mit Hülsen für Anker bekannt. Die Hülsen umfassen konusförmige Endstücke. Derartige Hülsen sind auch aus den Druckschriften DE 93 16 924 U1 , EP 1 544 380 A2 und DE 93 14 656 U1 bekannt.From the pamphlets EP 1 541 781 A1 and DE 34 05 976 A1 methods for mounting wall formwork and anchor systems with sleeves for anchors are known. The sleeves include conical end pieces. Such sleeves are also from the publications DE 93 16 924 U1 , EP 1 544 380 A2 and DE 93 14 656 U1 known.

Die vorliegende Erfindung bezieht sich auf den Fall, dass das Ankersystem eine Hülse umfasst, die nach dem Herausziehen des Ankerstabs zumindest teilweise im ausgehärteten Beton verbleibt. Die Montage einer Wandschalung soll in einem solchen Fall einfach und zuverlässig möglich sein. Ein System soll bereitgestellt werden, welches die Durchführung des Verfahrens ermöglicht.The present invention relates to the case that the anchor system comprises a sleeve which remains at least partially in the hardened concrete after the anchor rod has been pulled out. In such a case, the installation of wall formwork should be possible in a simple and reliable manner. A system is to be provided which enables the method to be carried out.

Die Aufgabe der Erfindung wird durch ein Verfahren mit den Merkmalen des ersten Anspruchs sowie durch ein Ankersystem mit den Merkmalen des Nebenanspruchs 2 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object of the invention is achieved by a method with the features of the first claim and by an anchor system with the features of independent claim 2. Advantageous refinements result from the subclaims.

Anspruch 1 betrifft ein Verfahren für das Montieren von zwei Wandschalungen. Dieses umfasst die nachfolgend genannten Schritte:
Auf der Rückseite der einen Wandschalung ist eine erste Arretiervorrichtung befestigt worden, bevor diese Wandschalung aufgestellt wird. Dies kann mit Hilfe von Schrauben oder Klemmmitteln geschehen sein. Befestigt meint, dass die Arretiervorrichtung fest und damit verliersicher mit der Wandschalung verbunden ist. Die Arretiervorrichtung kann allerdings grundsätzlich wieder von der Wandschalung mithilfe von Werkzeug gelöst werden. Die Befestigung bzw. feste Verbindung umfasst also grundsätzlich solche Befestigungsmittel wie Schrauben oder Klemmmittel, die ein Befestigen und Lösen ermöglichen. Es ist dadurch möglich, vor einem Aufstellen einer Wandschalung zunächst einen geeigneten Befestigungsort auf der Rückseite der Wandschalung auszuwählen.
Claim 1 relates to a method for assembling two wall formwork. This includes the following steps:
A first locking device has been attached to the rear of one of the wall formwork before this wall formwork is erected. This can be done with the help of screws or clamping means. Fastened means that the locking device is firmly and thus securely connected to the wall formwork. The locking device can, however, in principle be released again from the wall formwork with the aid of a tool. The fastening or fixed connection therefore basically comprises fastening means such as screws or clamping means that enable fastening and loosening. This makes it possible to first select a suitable fastening location on the back of the wall formwork before erecting a wall formwork.

Die Befestigung erfolgt aus Stabilitätsgründen grundsätzlich an einem stützenden Element wie Längsträger, Querriegel und Rahmen. Stützende Elemente sind hinreichend stabil und bestehen grundsätzlich aus Metall, so dass diese deshalb besonders geeignet sind.For reasons of stability, it is always fastened to a supporting element such as a side member, crossbar and frame. Supporting elements are sufficiently stable and basically consist of metal, so that they are particularly suitable.

Stützende Elemente einer Wandschalung sind während einer Montage und Demontage dauerhaft fest mit der Schalhaut verbunden. Eine Schalhaut kann beispielsweise mittels Schrauben mit den stützenden Elementen verbunden sein. Ein Lösen der Schalhaut von den stützenden Elementen ist nur für Reparaturzwecke vorgesehen. Ein Lösen der Schalhaut von den stützenden Elementen ist im Rahmen einer Montage und Demontage von Wandschalungen für ein Herstellen von Wänden weder vorgesehen noch erforderlich.Supporting elements of a wall formwork are permanently connected to the formwork skin during assembly and disassembly. A formwork skin can be connected to the supporting elements by means of screws, for example. Detaching the formlining from the supporting elements is only intended for repair purposes. A detachment of the formlining from the supporting elements is neither intended nor necessary in the context of an assembly and disassembly of wall formwork for the production of walls.

Die erste Arretiervorrichtung weist ein Rohrstück auf, welches im genannten befestigten Zustand in die eine erste Wandschalung hineinreicht. Die erste Arretiervorrichtung kann ein- oder mehrteilig sein. So kann das Rohrstück von einer Scheibe mit einem Loch senkrecht abstehen. Das Rohrstück mündet dann in das Loch der Scheibe ein. Die Scheibe kann von dem übrigen Teil der Arretiervorrichtung gelöst sein, also ein separatesThe first locking device has a pipe section which, in the fastened state mentioned, extends into a first wall formwork. The first locking device can be made up of one or more parts. The pipe section can protrude vertically from a disc with a hole. The pipe section then opens into the hole in the disc. The disc can be detached from the rest of the locking device, that is to say a separate part

Teil bilden. Die Scheibe kann aber auch dem übrigen Teil der Arretiervorrichtung verliersicher verbunden sein. Das Rohrstück reicht im montierten Zustand insbesondere wenigstens bis zur Außenseite der Schalhaut und schließt also mit der Schalhaut dann auf der Außenseite der Wandschalung bündig ab oder ragt gegenüber der Schalhaut ein Stück hervor. Der Außendurchmesser des Rohrstücks ist zumindest bei der Schalhaut geringfügig kleiner als der Innendurchmesser der Ankerstabbohrung bei der Schalhaut. Es verbleibt daher zwischen dem Rohrstück und der Ankerstabbohrung bei der Schalhaut ein kleiner Spalt, der insbesondere kleiner als 5 mm oder 3 mm, vorzugsweise kleiner als 2 mm, besonders bevorzugt kleiner als 1 mm ist, wenn die erste Arretiervorrichtung an der Wandschalung befestigt ist. Durch Vorsehen eines kleinen Spalts wird vermieden, dass Beton während der Herstellung von Wänden in die Wandschalung hinein fließen kann. Der Spalt erleichtert auf der anderen Seite das Montieren.Form part. However, the disk can also be connected captively to the rest of the locking device. In the assembled state, the pipe section extends in particular at least as far as the outside of the formwork facing and then closes up with the formwork facing flush with the outside of the wall formwork or protrudes slightly from the formwork facing. The outer diameter of the pipe section is at least slightly smaller in the case of the formwork skin than the inner diameter of the anchor rod bore in the case of the formwork skin. A small gap therefore remains between the pipe section and the anchor rod bore in the formwork, which is in particular smaller than 5 mm or 3 mm, preferably smaller than 2 mm, particularly preferably smaller than 1 mm, when the first locking device is attached to the wall formwork. By providing a small gap, it is avoided that concrete can flow into the wall formwork during the production of walls. The gap on the other hand makes assembly easier.

Für eine Montage werden die beiden Wandschalungen wie eingangs bereits beschrieben gegenüberliegend aufgestellt.For assembly, the two wall formworks are set up opposite one another, as already described at the beginning.

Ein Ankerstab wird teilweise von einer verschiebbar angeordneten Hülse umhüllt. Die Oberfläche der Hülse ist vorzugsweise glatt oder zumindest näherungsweise glatt. Da der Ankerstab nur teilweise von der Hülse umhüllt werden kann, ist die Hülse also kürzer als der Ankerstab. Andernfalls wäre es möglich, dass die Hülse den Ankerstab vollständig umhüllt.An anchor rod is partially encased by a slidably arranged sleeve. The surface of the sleeve is preferably smooth or at least approximately smooth. Since the anchor rod can only be partially enveloped by the sleeve, the sleeve is shorter than the anchor rod. Otherwise it would be possible for the sleeve to completely envelop the anchor rod.

Der Ankerstab wird durch Ankerstabbohrungen der beiden Wandschalungen hindurch geschoben und zwar derart, dass schließlich ein Ende der Hülse an dem Ende des Rohrstücks anliegt, welches in die eine erste Wandschalung hineinreicht. Es wird so eine Verbindung mit Dichtwirkung zwischen dem genannten Ende der Hülse und dem genannten Ende des Rohrstücks der ersten Arretiervorrichtung geschaffen.The anchor rod is pushed through anchor rod bores in the two wall formwork in such a way that finally one end of the sleeve rests against the end of the pipe section which extends into the first wall formwork. A connection with a sealing effect is thus created between said end of the sleeve and said end of the pipe section of the first locking device.

Das hindurch geschobene Ende des Ankerstabs wird mit der ersten Arretiervorrichtung mit Hilfe von Befestigungsmitteln fest verbunden, also an der ersten Arretiervorrichtung befestigt, beispielsweise durch Formschluss. Um dies zu ermöglichen, kann das hindurch geschobene Ende des Ankerstabs als Befestigungsmittel ein Gewinde aufweisen, weiches in ein als Befestigungsmittel dienendes Innengewinde der Arretiervorrichtung hineingeschraubt wird. Anstelle einer solchen Schraubverbindung kann aber auch beispielsweise eine Bajonettverbindung oder etwas Ähnliches vorgesehen sein, welches eine Befestigung des hindurch geschobenen Endes des Ankerstabs mit der ersten Arretiervorrichtung ermöglicht.The end of the anchor rod pushed through is firmly connected to the first locking device with the aid of fastening means, that is to say is fastened to the first locking device, for example by means of a form fit. In order to make this possible, the end of the anchor rod pushed through can have a thread as a fastening means, which thread is screwed into an internal thread of the locking device serving as a fastening means. Instead of such a screw connection, however, a bayonet connection or something similar can also be provided, for example, which enables the end of the anchor rod pushed through to be fastened to the first locking device.

Das nicht hindurch geschobene Ende des Ankerstabs wird mit einer zweiten Arretiervorrichtung durch Befestigungsmittel fest verbunden, so dass ein Rohrstück der zweiten Arretiervorrichtung in die Wandschalung hineinreicht und an die Hülse dichtend angrenzt. Das Rohrstück der zweiten Arretiervorrichtung ist ebenfalls vorzugsweise so dimensioniert wie das Rohrstück der ersten Arretiervorrichtung. Es schließt also im montierten Zustand vorzugsweise bündig mit der Außenseite der zweiten Schalung ab oder reicht über diese Außenseite hinaus. Es verbleibt dann wiederum vorzugsweise nur ein kleiner Spalt zwischen Schalhaut und Rohrstück, um so verbessert zu vermeiden, dass während der Herstellung einer Wand Beton in die zweite Wandschalung hineinfließt. Die Befestigungsmittel können so sein, dass durch Formschluss die zweite Arretiervorrichtung fest mit dem nicht hindurch geschobenen Ende des Ankerstabs verbunden werden kann. Das nicht hindurch geschobene Ende des Ankerstabs kann ein Gewinde aufweisen, welches mit einem Innengewinde der zweiten Arretiervorrichtung verschraubt werden kann, um so das nicht hindurch geschobene Ende des Ankerstabs mit der zweiten Arretiervorrichtung fest zu verbinden. Andere Befestigungsmittel wie Bajonettverbindungen sind ebenfalls möglich. Sind erste und zweite Arretiervorrichtung mit den Ankerstabenden fest verbunden worden, so können die beiden Wandschalungen nicht mehr voneinander gelöst werden.The end of the anchor rod that is not pushed through is firmly connected to a second locking device by fastening means, so that a pipe section of the second locking device extends into the wall formwork and adjoins the sleeve in a sealing manner. The pipe section of the second locking device is also preferably dimensioned in the same way as the pipe section of the first locking device. In the assembled state, it is therefore preferably flush with the outside of the second formwork or extends beyond this outside. Then again preferably only a small gap remains between the formwork facing and the pipe section in order to avoid, in an improved manner, that during the production of a wall concrete flows into the second wall formwork. The fastening means can be such that the second locking device can be firmly connected to the end of the anchor rod that is not pushed through by a form fit. The end of the anchor rod that is not pushed through can have a thread which can be screwed to an internal thread of the second locking device in order to firmly connect the end of the anchor rod that is not pushed through to the second locking device. Other fastening means such as bayonet connections are also possible. If the first and second locking devices have been firmly connected to the anchor rod ends, the two wall formwork can no longer be detached from one another.

Der Außendurchmesser der Hülse entspricht dem Außendurchmesser der Rohrstücke der Arretiervorrichtungen, damit ein Ende einer Hülse an ein Ende eines Rohrstücks dichtend angrenzen kann. Durch das Angrenzen wird vermieden, dass Beton während der Herstellung einer Wand unplanmäßig zum Ankerstab fließen kann. Der Innendurchmesser der Hülse und der Rohrstücke sind so gewählt, dass der Ankerstab durch die Hülse und die Rohrstücke hindurch geschoben werden kann. Es verbleibt dann ein geringes Spiel, also nur ein sehr kleiner Spalt, zwischen Hülse und Ankerstab sowie zwischen Rohrstücken und Ankerstab. Dieser Spalt beträgt vorzugsweise maximal 5 mm, weiter bevorzugt maximal 4, 3 oder 2 mm.The outer diameter of the sleeve corresponds to the outer diameter of the pipe sections of the locking devices so that one end of a sleeve can adjoin one end of a pipe section in a sealing manner. The adjoining prevents concrete from flowing unplanned to the tie rod during the construction of a wall. The inner diameter of the sleeve and the pipe sections are selected so that the anchor rod can be pushed through the sleeve and the pipe sections. There then remains a small amount of play, i.e. only a very small gap, between the sleeve and the anchor rod and between the pipe sections and the anchor rod. This gap is preferably a maximum of 5 mm, more preferably a maximum of 4, 3 or 2 mm.

Durch Vorsehen einer Hülse kann nach einem Aushärten von Beton ein Ankerstab besonders einfach herausgezogen werden. Das Verfahren ermöglicht es, eine Montage von nur einer Seite einer Wandschalung durchführen zu können. Da die Hülse zusammen mit dem Ankerstab durch eine Ankerstabbohrung im Rahmen der Montage hindurch gesteckt und folglich hindurch geschoben werden kann, ist eine schnelle und einfacheBy providing a sleeve, an anchor rod can be pulled out particularly easily after the concrete has hardened. The method makes it possible to assemble from only one side of a wall formwork. Since the sleeve, together with the anchor rod, can be inserted through an anchor rod bore during assembly and consequently pushed through it, it is quick and easy

Montage möglich. Durch das Vorsehen von Rohrstücken, an die die beiden Enden der Hülse im montierten Zustand angrenzen, wird für eine geeignete Dichtigkeit gesorgt, durch die vermieden wird, dass Beton unplanmäßig in die Wandschalungen eindringen oder zum Ankerstab gelangen kann.Assembly possible. By providing pipe pieces that are adjacent to the two ends of the sleeve in the assembled state, a suitable seal is ensured, which prevents concrete from penetrating the wall formwork or reaching the anchor rod.

Die Hülse besteht aus einem aus Kunststoff bestehenden Rohr und zwei Endstücken, wobei ein jedes Endstück lösbar mit einem Rohrende verbunden ist. Insbesondere ist ein jedes Endstück teilweise in das Rohr hinein gesteckt und so mit dem Rohr verbunden. Vorzugsweise werden die Endstücke dann klemmend durch das Rohr gehalten, sodass eine feste, aber lösbare Verbindung zwischen den Endstücken und dem Rohr vorhanden ist. Die Hülse besteht vorzugsweise vollständig aus Kunststoff.The sleeve consists of a tube made of plastic and two end pieces, each end piece being detachably connected to one end of the tube. In particular, each end piece is partially inserted into the pipe and thus connected to the pipe. The end pieces are then preferably held in a clamping manner by the pipe, so that there is a fixed but releasable connection between the end pieces and the pipe. The sleeve is preferably made entirely of plastic.

Das aus Kunststoff bestehende Rohr kann auf einer Baustelle vorteilhaft durch Ablängen eines Endlosrohrs erhalten werden, ohne exakt senkrecht zur Längsachse des Rohrs trennen zu müssen. Eine Stirnfläche des Rohrs muss also nicht exakt senkrecht zur Längsachse des Rohrs verlaufen, um Dichtigkeitsprobleme im montierten Zustand zu vermeiden. Durch die Endstücke wird sichergestellt, dass eine geeignete, dichte Verbindung zwischen der Hülse und den vorgenannten Rohrstücken der Arretiervorrichtungen möglich wird, selbst wenn in nicht idealer Weise abgelängt wurde. Auch ermöglicht das Vorsehen von Endstücken, dass eine zu kurze Rohrlänge ausgeglichen werden kann. Ist das Rohr zu kurz, so werden die Endstücke nicht in maximal möglicher Weise in das Rohr hineingesteckt, um den Mangel auszugleichen. Ein Bereich des Endstücks steht nach einem Hineinstecken gegenüber dem Ende des abgelängten Rohrs hervor, um ein Ende der Hülse zu bilden, das an einem Rohrstück einer Arretiervorrichtung dicht anliegen kann.The pipe made of plastic can advantageously be obtained on a construction site by cutting an endless pipe to length without having to cut exactly perpendicular to the longitudinal axis of the pipe. An end face of the pipe does not have to run exactly perpendicular to the longitudinal axis of the pipe in order to avoid sealing problems in the assembled state. The end pieces ensure that a suitable, tight connection between the sleeve and the aforementioned tubular pieces of the locking devices is possible, even if the length was not ideally cut. The provision of end pieces also makes it possible to compensate for a pipe length that is too short. If the pipe is too short, the end pieces are not inserted into the pipe as much as possible in order to compensate for the deficiency. After being inserted, a region of the end piece protrudes from the end of the cut-to-length tube in order to form an end of the sleeve which can lie tightly against a tube piece of a locking device.

Zur Durchführung des Verfahrens dient ein Ankersystem gemäß Anspruch 2, das einen Ankerstab, eine Hülse und zwei Arretiervorrichtungen umfasst. Eine jede Arretiervorrichtung kann mit einem Ende des Ankerstabs fest verbunden werden und zwar mithilfe von Befestigungsmitteln, die für ein Befestigen beispielsweise Gewinde umfassen können. Der Ankerstab kann durch die Hülse hindurch geschoben werden. Der Außendurchmesser des Ankerstabs ist daher kleiner als der Innendurchmesser der Hülse. Vorzugsweise ist der Außendurchmesser des Ankerstabs nur geringfügig kleiner als der Innendurchmesser der Hülse. Die Hülse ist kürzer als der Ankerstab, so dass der Ankerstab nur teilweise von der Hülse umhüllt werden kann. Eine jede Arretiervorrichtung weist Rohrstücke auf, die im montierten Zustand an die Hülse angrenzen. Die Rohrstücke sind also so vorhanden, dass diese im Rahmen einer Montage in Ankerlochbohrungen von Wandschalungen hineingesteckt werden können. Diese stehen daher von dem anderen Teil der Arretiervorrichtung ab, um dies zu ermöglichen. Der Außendurchmesser der Rohrstücke entspricht dem Außendurchmesser der Hülse aus bereits zuvor genannten Gründen.An anchor system according to claim 2, which comprises an anchor rod, a sleeve and two locking devices, is used to carry out the method. Each locking device can be fixedly connected to one end of the anchor rod with the aid of fastening means which, for example, can comprise threads for fastening. The anchor rod can be pushed through the sleeve. The outer diameter of the anchor rod is therefore smaller than the inner diameter of the sleeve. The outer diameter of the anchor rod is preferably only slightly smaller than the inner diameter of the sleeve. The sleeve is shorter than the anchor rod, so that the anchor rod is only partially supported by the Sleeve can be wrapped. Each locking device has pieces of pipe which, in the assembled state, adjoin the sleeve. The pipe sections are therefore available in such a way that they can be inserted into anchor holes in wall formwork during assembly. These therefore protrude from the other part of the locking device in order to make this possible. The outer diameter of the pipe pieces corresponds to the outer diameter of the sleeve for reasons already mentioned.

Die Hülse besteht vollständig oder zumindest überwiegend aus Kunststoff. Eine solche Hülse kann mit geringem technischem Aufwand hergestellt werden. insbesondere ist es möglich, auf einer Baustelle eine geeignet lange Hülse durch Ablängen eines Endlosrohrs zu erhalten.The sleeve consists entirely or at least predominantly of plastic. Such a sleeve can be manufactured with little technical effort. In particular, it is possible to obtain a suitably long sleeve on a construction site by cutting an endless pipe to length.

Die Hülse umfasst zwei Endstücke, die lösbar mit Enden eines Rohrs verbunden sind. Bei einem Endlosrohr muss dann nicht auf exakt senkrechte Schnitte relativ zur Längsachse des Rohrs geachtet werden, um daraus eine geeignete Hülse fertigen zu können, deren Enden geeignet dicht an Rohrstücken von Arretiervorrichtungen anliegen können.The sleeve comprises two end pieces which are releasably connected to ends of a tube. In the case of an endless pipe, it is then not necessary to pay attention to exactly perpendicular cuts relative to the longitudinal axis of the pipe in order to be able to manufacture a suitable sleeve therefrom, the ends of which can fit suitably close to pipe sections of locking devices.

Ein Endstück verbreitert sich zu einem Ende hin vorzugsweise stufenförmig. Durch die Stufenform kann sichergestellt werden, dass ein Endstück in ein Rohr der Hülse hineingesteckt werden kann, wobei die stufenförmige Verbreiterung gegenüber dem Ende des Rohrs hervorsteht. Ein Endstück wird dadurch in zwei Abschnitte unterteilt, die durch eine Stufe voneinander getrennt sind. Der eine Abschnitt ist für ein Einstecken in ein Rohr vorgesehen und kann daher als Einsteckabschnitt bezeichnet werden. Der andere Abschnitt ist gegenüber dem Einsteckabschnitt verbreitert und kann daher verbreiteter Abschnitt genannt werden. Durch eine solche Unterteilung in Einsteckabschnitt und verbreiterten Abschnitt wird sichergestellt, dass das entsprechende Ende der Hülse durch das Endstück gebildet wird und zwar durch den verbreiterten Bereich bzw. verbreiterten Abschnitt des Endstücks. Das verbreiterte Ende der Hülse, also der verbreiterte Abschnitt, weist dann einen größeren Außendurchmesser auf als der Innendurchmesser des entsprechenden Rohrs. Der Außendurchmesser des verbreiterten Bereichs bzw. des verbreiterten Abschnitts des Endstücks entspricht dem Außendurchmesser des Rohrs.An end piece widens towards one end, preferably in a stepped manner. The step shape can ensure that an end piece can be inserted into a tube of the sleeve, the step-like widening protruding from the end of the tube. An end piece is thereby divided into two sections, which are separated from one another by a step. One section is provided for insertion into a pipe and can therefore be referred to as an insertion section. The other section is widened compared to the insertion section and can therefore be called a widened section. Such a subdivision into the plug-in section and the widened section ensures that the corresponding end of the sleeve is formed by the end piece, specifically by the widened area or widened section of the end piece. The widened end of the sleeve, that is to say the widened section, then has a larger outer diameter than the inner diameter of the corresponding tube. The outside diameter of the widened area or the widened section of the end piece corresponds to the outside diameter of the pipe.

Ein Bereich der Stufe verläuft vorzugsweise V-förmig oder wellenförmig. Im Rahmen einer Demontage kann dann ein Endstück durch Drehen des Endstücks um seine Längsachse leicht vom ausgehärten Beton gelöst werden, da die V-Form oder die Stufenform dann ähnlich wie ein Gewinde wirken. Aufgrund der V-Form bzw. der Wellenform kommt es allerdings im Unterschied zu einem Gewinde nicht auf eine bestimmte Drehrichtung an, um ein Endstück aus ausgehärtetem Beton herausdrehen zu können.A region of the step is preferably V-shaped or wave-shaped. During dismantling, an end piece can then be easily detached from the hardened concrete by rotating the end piece around its longitudinal axis, since the V-shape or the step shape then act like a thread. Due to the V-shape or the wave shape, however, in contrast to a thread, a certain direction of rotation is not important in order to be able to unscrew an end piece from hardened concrete.

Ein Abschnitt eines Endstücks kann grundsätzlich in das Rohr der Hülse hineingesteckt werden. Ein maximale Außendurchmesser dieses Einsteckabschnitts kann geringfügig größer als der Innendurchmesser des Rohrs sein, um eine Klemmwirkung zwischen Endstück und Rohr erzielen zu können. Das Endstück der Hülse kann mit dem Rohr dann durch Klemmwirkung lösbar verbunden werden. Grundsätzlich kann das Endstück auch auf andere Weise mit der Hülse klemmend verbunden sein bzw. werden, beispielsweise alternativ oder ergänzend mithilfe von ein oder mehreren Dichtlippen. Das Endstück soll allerdings immer von dem Rohr gelöst werden können, um dieses im Rahmen einer Demontage von einer fertig gestellten Wand entfernen zu können. Nur das Rohr verbleibt dann also gegenüber den Wandaußenseiten zurückversetzt in der fertig gestellten Wand.A section of an end piece can in principle be inserted into the tube of the sleeve. A maximum outside diameter of this insertion section can be slightly larger than the inside diameter of the pipe in order to be able to achieve a clamping effect between the end piece and the pipe. The end piece of the sleeve can then be releasably connected to the pipe by a clamping effect. In principle, the end piece can also be clamped to the sleeve in another way, for example alternatively or additionally with the aid of one or more sealing lips. However, the end piece should always be able to be detached from the pipe in order to be able to remove it from a finished wall during dismantling. Only the pipe then remains set back in the finished wall with respect to the outer sides of the wall.

Der vorgenannte Einsteckabschnitt eines Endstücks verjüngt sich zu seinem freien Ende hin vorzugsweise konusförmig oder trichterförmig, um den Einsteckabschnitt problemlos in das Rohr hineinstecken zu können. Auch der verbreiterte Abschnitt verjüngt sich vorteilhaft konusförmig oder trichterförmig in Richtung des freien Endes des Einsteckabschnitts, um ein Entfernen eines Endstücks aus einer fertig gestellten Wand zu erleichtern.The aforementioned plug-in section of an end piece tapers towards its free end, preferably conically or funnel-shaped, in order to be able to plug the plug-in section into the pipe without any problems. The widened section also tapers advantageously conically or funnel-shaped in the direction of the free end of the insertion section in order to make it easier to remove an end piece from a finished wall.

Um eine geeignete Klemmwirkung zwischen Rohr und Endstück erzielen zu können, umfasst das Endstück vorzugsweise zumindest eine nachgiebige Dichtlippe, die nach außen absteht. Insbesondere der Einsteckabschnitt, weist eine solche nachgiebige Dichtlippe auf, die vorzugsweise um die Längsachse des Einsteckabschnitts ring- oder kreisförmig herum verläuft. Besonders bevorzugt gibt es zwei oder drei solcher Dichtlippen, um eine geeignete Klemmwirkung zwischen Endstück und Rohr zu erzielen und außerdem zuverlässig vor eindringendem Beton zu schützen. Durch solche ein oder mehrere Dichtlippen wird also verbessert vermieden, dass Beton während der Herstellung einer Wand nachteilhaft zum Ankerstab gelangen kann.In order to be able to achieve a suitable clamping effect between the pipe and the end piece, the end piece preferably comprises at least one flexible sealing lip which protrudes outward. In particular, the plug-in section has such a flexible sealing lip, which preferably runs in a ring or circular shape around the longitudinal axis of the plug-in section. It is particularly preferred that there are two or three such sealing lips in order to achieve a suitable clamping effect between the end piece and the pipe and also to reliably protect against penetrating concrete. One or more sealing lips of this type thus improve the avoidance of concrete being able to disadvantageously reach the anchor rod during the production of a wall.

Ein Endstück einer Hülse ist vorzugsweise aus einem harten Kunststoff und einem weichen Kunststoff gebildet. Der weiche Kunststoff ist nachgiebiger, also kompressibler, als der harte Kunststoff. Der weiche Kunststoff verhält sich insbesondere elastisch. Der aus dem weichen Kunststoff gebildete Bereich verläuft ringförmig und bildet ein Ende des Endstücks. Der weiche Kunststoff gehört insbesondere zum verbreiterten Abschnitt des Endstücks. Durch den weichen Kunststoff wird verbessert erreicht, dass zwischen der Hülse und einem Rohrstück einer Arretiervorrichtung eine dichte Verbindung erzielt werden kann. Weiter verbessert wird also erreicht, dass Beton während der Herstellung einer Wand nicht unplanmäßig zum Ankerstab gelangen und/oder in eine Wandschalung hineinfließen kann.An end piece of a sleeve is preferably formed from a hard plastic and a soft plastic. The soft plastic is more flexible, i.e. more compressible, than the hard plastic. The soft plastic is particularly elastic. The area formed from the soft plastic runs in a ring shape and forms one end of the end piece. The soft plastic belongs in particular to the widened section of the end piece. The soft plastic ensures that a tight connection can be achieved between the sleeve and a pipe section of a locking device. It is thus further improved that during the production of a wall, concrete cannot reach the tie rod unplanned and / or flow into a wall formwork.

Ein Endstück der Hülse weist an einem Ende vorzugsweise eine nach außen hin abstehende, ringförmig verlaufende, vorzugsweise biegsame Lippe auf. Diese besteht insbesondere aus dem weichen, nachgiebigen Kunststoffmaterial. Hierdurch wird weiter verbessert vermieden, dass Beton während der Herstellung einer Wand unplanmäßig in eine Wandschalung hineinfließen kann.At one end, an end piece of the sleeve preferably has an outwardly protruding, annularly extending, preferably flexible lip. This consists in particular of the soft, flexible plastic material. This further improves the avoidance of concrete being able to flow into a wall formwork in an unplanned manner during the production of a wall.

Ein freies Ende eines Endstücks weist vorzugsweise eine nicht kreisförmige Innenkontur auf. Es ist so möglich, ein Werkzeug in ein Endstück so hinein zu stecken, dass durch Drehen des Werkzeugs das Endstück gedreht werden kann, um dieses nach einem Aushärten von Beton entfernen zu können.A free end of an end piece preferably has a non-circular inner contour. It is thus possible to insert a tool into an end piece in such a way that, by turning the tool, the end piece can be rotated in order to be able to remove it after the concrete has hardened.

Die nicht kreisförmige Innenkontur umfasst vorzugsweise zwei sich gegenüberliegende Ausbuchtungen, in die ein Ende eines üblich großen Zollstocks, auch Meterstab oder Gliedermaßstab genannt, im zusammengeklappten Zustand hineingesteckt werden kann. Der Zollstock kann dann als Werkzeug dienen, um Endstücke aus einer fertig gestellten Wand durch Drehen des Zollstocks herausdrehen zu können.

Die Figuren 1 und 2 zeigen ein Endstück 1 für eine Hülse. Das Endstück besteht vollständig aus Kunststoff. Das Endstück umfasst einen Abschnitt 2, der in ein Rohr der Hülse hingesteckt wird, der Einsteckabschnitt 2 genannt wird. Dieser Einsteckabschnitt 2 verjüngt sich konusförmig zu seinem freien Ende 3 hin. Das Endstück 1 verbreitert sich zu seinem anderen Ende hin stufenförmig. Es gibt daher einen verbreiterten Bereich bzw. einen verbreiterten Abschnitt 4. Der verbreiterte Abschnitt 4 verjüngt sich ebenfalls konusförmig zum Ende 3 hin.the Figures 1 and 2 show an end piece 1 for a sleeve. The end piece is made entirely of plastic. The end piece comprises a section 2 which is inserted into a tube of the sleeve, which is called the plug-in section 2. This insertion section 2 tapers conically towards its free end 3. The end piece 1 widens in steps towards its other end. There is therefore a widened area or a widened section 4. The widened section 4 also tapers conically towards the end 3.

Die Stufe 5 verläuft wellenförmig um die Längsachse 6 des Endstücks 1 herum. Der verbreiterte Abschnitt 4 bildet einen gegenüber einem Rohr der Hülse hervorstehendes Teil. Die Innenkontur des hervorstehenden Teils bzw. des verbreiteten Abschnitts 4 weist an seinem offenen Ende zwei gegenüberliegende Ausbuchtungen 7 so auf, dass ein üblicher Zollstock im zusammengeklappten Zustand mit einem Ende, also einer Stirnseite, in beide Ausbuchtungen 7 zeitgleich hineinreichen kann. Die Innenkontur ist aufgrund der Ausbuchtungen 7 nicht kreisförmig.The step 5 runs in an undulating manner around the longitudinal axis 6 of the end piece 1. The widened section 4 forms a part protruding from a tube of the sleeve. The inner contour of the protruding part or the widened section 4 has two opposite bulges 7 at its open end so that a conventional folding rule can reach into both bulges 7 at the same time with one end, i.e. one end face. The inner contour is not circular due to the bulges 7.

An dem Ende mit den Ausbuchtungen 7 gibt es einen ringförmigen Bereich 8, der aus einem weichen Kunststoff besteht im Vergleich zu dem Kunststoff, aus dem das Endstück 1 darüber hinaus besteht und der daher harter Kunststoff genannt wird. An seinem freien Ende umfasst der aus einem weichen Kunststoff bestehende ringförmige Bereich 8 eine radial abstehende, umlaufende Lippe 9, die elastisch biegsam ist. Der Einsteckabschnitt 2 umfasst zwei umlaufende, elastisch biegsame Dichtlippen 10, die radial abstehen.At the end with the bulges 7 there is an annular area 8 which consists of a soft plastic compared to the plastic from which the end piece 1 is also made and which is therefore called hard plastic. At its free end, the annular region 8 made of a soft plastic comprises a radially protruding, circumferential lip 9 which is elastically flexible. The insertion section 2 comprises two circumferential, elastically flexible sealing lips 10 which protrude radially.

Die Figur 3 zeigt in einer Seitenansicht eine Hülse 11 mit einem aus Kunststoff bestehenden Rohr 12, in welches Endstücke 1, die in den Figuren 1 und 2 gezeigt sind, hineingesteckt worden sind. Die verbreiterten Abschnitte 4 bilden die beiden Enden der Hülse 11 und sind nicht in das Rohr 12 hineingesteckt worden, was aufgrund der verbreiterten Abschnitte 4 auch nicht möglich ist. Der Außendurchmesser der verbreiterten Abschnitte 4 entspricht dem Außendurchmesser des Rohres 12. Aufgrund der Dichtlippen 10 werden die beiden Endstücke 4 klemmend durch das Rohr 12 gehalten.the Figure 3 shows a side view of a sleeve 11 with a tube 12 made of plastic, in which end pieces 1, which are in the Figures 1 and 2 shown have been inserted. The widened sections 4 form the two ends of the sleeve 11 and have not been inserted into the tube 12, which is also not possible due to the widened sections 4. The outside diameter of the widened sections 4 corresponds to the outside diameter of the pipe 12. Due to the sealing lips 10, the two end pieces 4 are held by the pipe 12 in a clamping manner.

Die Figur 4 zeigt ausschnittsweise in einer Schnittdarstellung zwei montierte Wandschalungen 12 und 13, die jeweils eine Schalhaut 14 und daran befestigte stützende Elemente 15 umfassen. Auf der Rückseite der einen ersten Wandschalung 13 ist eine erste im Schnitt dargestellte Arretiervorrichtung 16 mithilfe von ein oder mehreren Schrauben 17 befestigt worden, bevor diese erste Wandschalung 13 aufgestellt wurde. Die Schraube 17 führt in dem gezeigten Beispiel durch eine rechtwinklig abstehende Lasche 18 hindurch, so dass die Schraube 17 seitlich am stützenden Element 15 festgeschraubt werden konnte.the Figure 4 shows a detail in a sectional view of two mounted wall formworks 12 and 13, each of which has a formwork skin 14 and supports attached to it Elements 15 include. On the rear side of the first wall formwork 13, a first locking device 16, shown in section, has been fastened with the aid of one or more screws 17 before this first wall formwork 13 was erected. In the example shown, the screw 17 leads through a bracket 18 protruding at right angles, so that the screw 17 could be screwed tightly to the side of the supporting element 15.

Die erste Arretiervorrichtung 16 weist ein Rohrstück 19 auf, welches im befestigten Zustand in die eine erste Wandschalung 13 hineinreicht und zwar bis zur Außenseite 20 der Schalhaut 14. Das freie Ende des Rohrstücks 19 schließt bündig mit der Außenseite 20 der Schalhaut 14 ab. Wie in der Figur 4 angedeutet, wurden die beiden Wandschalungen 12 und 13 gegenüberliegend aufgestellt. Ein Ankerstab 21 weist an seinen beiden Enden Außengewinde 22 auf. Der Ankerstab 21 wurde durch die Hülse 11 hindurch geschoben und wird im montierten Zustand wie in der Figur 4 gezeigt von der Hülse 11 teilweise umhüllt. Der Ankerstab 21 wurde anschließend zusammen mit der Hülse 11 zunächst durch die links gezeigte Ankerstabbohrung 23 der Wandschalung 12 hindurch geschoben, bis das rechts gezeigte Ende des Endstücks 1 der Hülse 11 an dem Ende des rechts gezeigten Rohrstücks 19 dicht anlag.The first locking device 16 has a pipe section 19 which, when fastened, extends into a first wall formwork 13, namely as far as the outside 20 of the formwork facing 14. The free end of the pipe section 19 is flush with the outside 20 of the formwork facing 14. Like in the Figure 4 indicated, the two wall formwork 12 and 13 were set up opposite one another. An anchor rod 21 has external threads 22 at both of its ends. The anchor rod 21 has been pushed through the sleeve 11 and is in the assembled state as in FIG Figure 4 shown partially encased by the sleeve 11. The anchor rod 21 was then pushed together with the sleeve 11 through the anchor rod bore 23 of the wall formwork 12 shown on the left until the end of the end piece 1 of the sleeve 11 shown on the right was tight against the end of the pipe section 19 shown on the right.

Das rechts gezeigte Ende des Ankerstabs 21, welches schließlich auch durch das Ankerloch 23 der rechts gezeigten Wandschalung 13 hindurch geschoben wurde, wurde anschließend mit der ersten Arretiervorrichtung 16 fest verbunden, indem das Gewinde 22 des rechts gezeigten Endes des Ankerstabs 21 in ein Innengewinde der ersten Arretiervorrichtung 16 hinein geschraubt wurde.The end of the anchor rod 21 shown on the right, which was finally pushed through the anchor hole 23 of the wall formwork 13 shown on the right, was then firmly connected to the first locking device 16 by inserting the thread 22 of the end of the anchor rod 21 shown on the right into an internal thread of the first Locking device 16 was screwed into it.

Das links gezeigte, nicht hindurch gesteckte Ende des Ankerstabs 21 wurde anschließend mit der links gezeigten zweiten Arretiervorrichtung 24 fest verbunden, so dass das Rohrstück 19 der zweiten Arretiervorrichtung 24 in die zweite Wandschalung 12 hineinreicht und zwar bis Außenseite 20 der links gezeigten Schalhaut 14. Das freie Ende des Rohrstücks 19 der zweiten Arretiervorrichtung 24 liegt dann dicht an dem freien Ende des links gezeigten Endstück 1 an. Das links gezeigte Ende des Ankerstabs 21 wurde ebenfalls durch eine Schraubverbindung mit der zweiten Arretiervorrichtung 24 verbunden.The end of the anchor rod 21, shown on the left and not inserted through, was then firmly connected to the second locking device 24 shown on the left, so that the pipe section 19 of the second locking device 24 extends into the second wall formwork 12, to the outside 20 of the formwork skin 14 shown on the left The free end of the pipe section 19 of the second locking device 24 then lies tightly against the free end of the end piece 1 shown on the left. The end of the anchor rod 21 shown on the left was also connected to the second locking device 24 by a screw connection.

Auch die zweite Arretiervorrichtung 24 kann zusätzliche Befestigungsmittel wie Schraube und/oder rechtwinklig abstehende Lasche umfassen, mit denen die zweite Arretiervorrichtung 24 an dem stützenden Element 15 der zweiten Wandschalung 12 befestigt werden kann.The second locking device 24 can also comprise additional fastening means such as a screw and / or tab protruding at right angles, with which the second locking device 24 can be fastened to the supporting element 15 of the second wall formwork 12.
