Definitions
- the invention relates to a method for mounting a wall formwork and an anchor system for a wall formwork for carrying out the method.
- An anchor system in the context of the present invention is used in formwork technology in the concreting of reinforced concrete structures in order to mount wall formworks.
- a wall formwork includes a formwork on the front and on the back of the formwork supporting elements such as side members, crossbar and frame. In the erected condition of a wall formwork, a side member extending in the vertical direction and a cross bar 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.
- Opposing wall formworks are usually held by a plurality of anchor systems.
- the anchor rods are inserted through openings in the wall formworks and attached at their ends to the respective formwork skin supporting elements by means of locking devices so that at least the force acting on the anchor rods during concreting tensile force is absorbed.
- These openings passing through the wall formwork are also called anchor rod bores.
- An adjustment formwork is a wall formwork, which is set up first. Following this, the closing formwork opposite the formwork is set up. Adjustment formwork and closing formwork are part of the assembly connected by one or more anchor systems. Concrete is poured into the space between the shuttering and shuttering. By curing the concrete creates a wall.
- an anchor rod on a thread on which nuts are screwed as Ankerfix micha.
- the central region of such an anchor rod, to which concrete can adjoin during concreting advantageously has either a smooth surface or is at least wrapped during concreting by a sleeve with a smooth surface. Otherwise, a thread of an anchor rod would be embedded in concrete. The anchor rod can then no longer be easily pulled out of the hardened concrete.
- the maximum effective length of the anchor rod and thus the thickness (thickness) of the wall to be concreted is therefore regularly determined by the length of the central anchor rod region with a smooth surface.
- 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 may be placed between the shell skins in the volume of the wall to be concreted, which can absorb the compressive forces created during concreting, thereby ensuring that these compressive forces do not undesirably affect the wall thickness, i. Reduce.
- the locking devices can be attached to the wall formwork, so that they are able to absorb pressure forces.
- the anchor rod is released from a locking device and from the Concrete wall pulled out. If necessary, the upper side of a closing formwork is previously hung, for example, on a hook of a crane, so that it does not fall over once all tie rods have been pulled out. For example, with the help of the crane, the wall formworks are finally suitably displaced to produce a next wall or a next wall section. If the wall formwork has been moved, then the anchor systems are mounted or attached to the wall formwork again.

Description
Die Erfindung betrifft ein Verfahren für eine Montage einer Wandschalung sowie ein Ankersystem für eine Wandschalung zur Durchführung des Verfahrens.The invention relates to a method for mounting a wall formwork and an anchor system for a wall formwork 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 Wandschalung umfasst auf der Vorderseite eine Schalhaut und auf der Rückseite die Schalhaut stützende Elemente wie Längsträger, Querriegel und Rahmen. Im aufgestellten Zustand einer Wandschalung erstrecken sich ein Längsträger in vertikaler Richtung und ein Querriegel in horizontaler Richtung.An anchor system in the context of the present invention is used in formwork technology in the concreting of reinforced concrete structures in order to mount wall formworks. A wall formwork includes a formwork on the front and on the back of the formwork supporting elements such as side members, crossbar and frame. In the erected condition of a wall formwork, a side member extending in the vertical direction and a cross bar 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 Wandschalungen werden in der Regel durch eine Mehrzahl von Ankersystemen gehalten. Die Ankerstäbe werden durch Öffnungen in den Wandschalungen hindurch gesteckt und an ihren Enden an den die jeweilige Schalhaut stützenden Elementen 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. Opposing wall formworks are usually held by a plurality of anchor systems. The anchor rods are inserted through openings in the wall formworks and attached at their ends to the respective formwork skin supporting elements by means of locking devices so that at least the force acting on the anchor rods during concreting tensile force is absorbed. These openings passing 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 Aushärten des Betons entsteht eine Wand.In formwork technology, a distinction is made between an adjustment formwork and a closing formwork. An adjustment formwork is a wall formwork, which is set up first. Following this, the closing formwork opposite the formwork is set up. Adjustment formwork and closing formwork are part of the assembly connected by one or more anchor systems. Concrete is poured into the space between the shuttering and shuttering. By curing the concrete creates a wall.
Üblicherweise weisen ein oder die beiden Enden eines Ankerstabs ein Gewinde auf, auf welche Schraubenmuttern als Ankerfixierungen aufgeschraubt werden. Der mittlere Bereich eines solchen Ankerstabes, an den während des Betonierens Beton angrenzen kann, weist vorteilhaft entweder eine glatte Oberfläche auf oder wird zumindest während des Betonierens von einer Hülse mit glatter Oberfläche umhüllt. Andernfalls würde ein Gewinde eines Ankerstabs einbetoniert. Der Ankerstab kann dann nicht mehr unproblematisch aus dem ausgehärteten Beton herausgezogen werden.Usually, one or the two ends of an anchor rod on a thread on which nuts are screwed as Ankerfixierungen. The central region of such an anchor rod, to which concrete can adjoin during concreting, advantageously has either a smooth surface or is at least wrapped during concreting by a sleeve with a smooth surface. Otherwise, a thread of an anchor rod would be embedded in concrete. The anchor rod can then no longer be easily pulled out of the hardened concrete.
Die maximal wirksame Länge des Ankerstabs und damit die Stärke (Dicke) der zu betonierenden Wand wird daher regelmäßig durch die Länge des mittleren Ankerstabbereichs mit glatter Oberfläche 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.The maximum effective length of the anchor rod and thus the thickness (thickness) of the wall to be concreted is therefore regularly determined by the length of the central anchor rod region with a smooth surface. 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.
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. Alternativ oder ergänzend können die Arretierungsvorrichtungen an den Wandschalungen befestigt werden, damit diese auch Druckkräfte aufzunehmen vermögen.Spacers may be placed between the shell skins in the volume of the wall to be concreted, which can absorb the compressive forces created during concreting, thereby ensuring that these compressive forces do not undesirably affect the wall thickness, i. Reduce. Alternatively or additionally, the locking devices can be attached to the wall formwork, so that they are able to absorb pressure forces.
Ist der zwischen zwei Wandschalungen gegossene Beton ausgehärtet, so wird der Ankerstab von 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. 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.If the poured between two wall formworks hardened concrete, the anchor rod is released from a locking device and from the Concrete wall pulled out. If necessary, the upper side of a closing formwork is previously hung, for example, on a hook of a crane, so that it does not fall over once all tie rods have been pulled out. For example, with the help of the crane, the wall formworks are finally suitably displaced to produce a next wall or a next wall section. If the wall formwork has been moved, then the anchor systems are mounted or attached to the wall formwork again.
Aus der Druckschrift
Die vorgenannten, aus dem Stand der Technik bekannten Merkmale können einzeln oder in beliebiger Kombination mit dem nachfolgend beschriebenen erfindungsgemäßen Gegenstand kombiniert werden, soweit nachfolgend nichts anderes angegeben wird.The abovementioned features known from the prior art can be combined individually or in any desired combination with the object according to the invention described below, unless stated otherwise below.
Es ist Aufgabe der Erfindung, die Montage einer Wandschalung zu vereinfachen sowie dafür ein Ankersystem bereitzustellen.It is an object of the invention to simplify the installation of a wall formwork and to provide an anchor system.
Die Aufgabe der Erfindung wird durch ein Verfahren mit den Merkmalen des ersten Anspruchs sowie durch ein Ankersystem mit den Merkmalen des Nebenanspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object of the invention is achieved by a method having the features of the first claim and by an anchor system having the features of the independent claim. Advantageous embodiments emerge from the subclaims.
Um eine Montage zu vereinfachen und zu beschleunigen, umfasst der Ankerstab eines Ankersystems an dem Ende, welches nicht durch Wandschalungen für eine Demontage herausgezogen wird bzw. umgekehrt für eine Montage in Ankerstabbohrungen hineingesteckt wird, ein Rastermaß für die Herstellung von unterschiedlich dicken Wänden. Durch eine Montage von Ankersystemen mit Rastermaß gelingt es einfach und genau, eine gemäß Rastermaß vorgesehene Wanddicke einzustellen. Das Vorsehen eines Rastermaßes bei einem Ankersystem vermag eine Montage zu beschleunigen und zu vereinfachen.To simplify and accelerate assembly, the anchor rod of an anchor system at the end, which is not pulled out by wall formwork for disassembly or vice versa for mounting in anchor rod holes is inserted, a grid for the production of different thickness walls. By mounting armature systems with grid size, it is easy and accurate to set a wall thickness in accordance with the grid. The provision of a grid in an anchor system can accelerate assembly and simplify.
Es wird der Ankerstab zunächst durch Ankerstabbohrungen von Schließ- und Stellschalung hindurchgeschoben und das hindurchgeschobene Ende mit einer Arretiervorrichtung verbunden und zwar insbesondere verschraubt. Diese Arretiervorrichtung ist an der Rückseite der entsprechenden Wandschalung vorzugsweise fest montiert, so zum Beispiel an einem Längsträger dieser Wandschalung festgeschraubt. Bevorzugt handelt es sich bei dieser Wandschalung um eine Stellschalung, um so besonders schnell montieren zu können. Der Ankerstab wird an einer vorgegebenen Position mit der Arretiervorrichtung verbunden, so zum Beispiel verschraubt. Um die vorgegebene Position schnell und einfach aufzufinden, gibt es bevorzugt einen Anschlag. Erreicht das hindurchgeschobene Ende des Ankerstabs den Anschlag, so ist die vorgegebene Position erreicht. Im Fall einer Schraubverbindung verhindert der Anschlag ein weiteres Hineinschrauben. Bei dieser Ausführungsform wird der Ankerstab also in maximal möglicher Weise in das Gewinde der Arretiervorrichtung hineingeschraubt.It is the anchor rod first pushed through anchor rod holes of closing and setting formwork and the pushed-through end connected to a locking device and in particular screwed. This locking device is preferably fixedly mounted on the back of the corresponding wall formwork, so for example screwed to a side rail of this wall formwork. Preferably, this wall formwork is a setting formwork, so as to be able to assemble particularly quickly. The anchor rod is connected at a predetermined position with the locking device, such as bolted. In order to find the predetermined position quickly and easily, there is preferably a stop. If the pushed-through end of the anchor rod reaches the stop, the predetermined position has been reached. In the case of a screw connection, the stop prevents further screwing in. In this embodiment, the anchor rod is thus screwed in the maximum possible way in the thread of the locking device.
Im Anschluss daran wird auf der gegenüberliegenden Seite das nicht hindurch gesteckte Ende des Ankerstabs mit der hier vorgesehenen Arretiervorrichtung so verbunden, dass diese Verbindung an dem gewählten Rastermaß ausgerichtet ist. Es wird so besonders schnell und einfach der gewünschte Abstand zwischen den beiden Schalungen eingestellt. Die Wand mit der gewünschten Dicke kann gegossen werden, sobald beide Arretiervorrichtungen die jeweilige Rückwand kontaktieren und zwar grundsätzlich die Rückwand eines stützenden Elements. Sind die Arretiervorrichtungen fest an der jeweiligen Wandschalung montiert, dann kontaktieren diese die Rückseite der jeweiligen Wandschalung.Following this, the not inserted end of the anchor rod is connected to the locking device provided here on the opposite side so that this connection is aligned with the selected grid. It gets so fast and fast simply set the desired distance between the two formworks. The wall with the desired thickness can be cast as soon as both locking devices contact the respective rear wall, in principle the rear wall of a supporting element. If the locking devices are firmly mounted on the respective wall formwork, then they contact the back of the respective wall formwork.
In einer Ausführungsform ist für ein Ausrichten an einem Rastermaß ein Stellglied vorgesehen, welches gemäß Rastermaß positioniert wird. Das Stellglied ist in einer einfachen Ausführungsform eine Stellschraube, die durch Schrauben in eine Position gemäß Rastermaß bewegt wird. Alternativ kann das Stellglied eine Hülse sein, durch die der Ankerstab hindurch gesteckt ist.In one embodiment, an actuator is provided for alignment with a grid dimension, which is positioned according to grid. The actuator is in a simple embodiment, an adjusting screw which is moved by screws in a position according to grid. Alternatively, the actuator may be a sleeve through which the anchor rod is inserted.
Als Rastermaß kann der Ankerstab eine Mehrzahl von Bohrungen umfassen, die untereinander einen Abstand aufweisen. Befindet sich in einer Ausführungsform das Stellglied in einer Position gemäß Rastermaß, so wird das Stellglied in einer einfachen Ausführungsform mittels eines Splints, einer Schraube oder eines Bolzens fixiert. Der Bolzen oder Splint wird beispielsweise für das Fixieren durch ein Loch des Stellglieds und die Bohrung im Ankerstab so hineingesteckt, dass dadurch das Stellglied nicht mehr von seiner Position gelöst werden kann. Das Stellglied und und/ oder die Bohrungen im Ankerstab können ein Gewinde umfassen, um das Stellglied mittels Schraube zu fixieren.As a grid, the anchor rod may comprise a plurality of holes which have a distance from each other. In one embodiment, the actuator is in a position according to grid, so the actuator is fixed in a simple embodiment by means of a splint, a screw or a bolt. The pin or split pin is inserted, for example, for fixing through a hole of the actuator and the hole in the anchor rod so that thereby the actuator can not be released from its position. The actuator and / or the holes in the anchor rod may include a thread to fix the actuator by means of a screw.
Befindet sich das Stellglied in einer Position gemäß Rastermaß, wird das Stellglied mittelbar oder unmittelbar mit der Rückseite der angrenzenden Wandschalung verbunden. Die Wandschalung wird so in die Position bewegt, die erforderlich ist, um eine Wand gewünschter Wanddicke herzustellen.The actuator is in a position according to grid, the actuator is directly or indirectly connected to the back of the adjacent wall formwork. The wall formwork is thus moved to the position required to make a wall of desired wall thickness.
Um das Stellglied mit der Rückseite einer Wandschalung zu verbinden, können zum Beispiel ein oder mehreren Schrauben vorgesehen sein, die durch geeignet angeordnete Löcher im Stellglied hindurchführen und in dafür vorgesehene Gewinde an der Rückseite der benachbarten Schalung hineingeschraubt werden.To connect the actuator to the back of a wall formwork, for example, one or more screws may be provided which pass through suitably arranged holes in the actuator and are screwed into designated threads on the back of the adjacent formwork.
Der Teil eines Ankersystems, der für eine Demontage einer Wandschalung herausgezogen wird, umfasst neben dem Ankerstab grundsätzlich eine Arretiervorrichtung oder zumindest einen Teil davon. Für eine Montage wird der Ankerstab in Ankerstabbohrungen von Schließ- und Stellschalungen hindurch gesteckt. Ist zuvor die vorgenannte Arretiervorrichtung oder ein Teil davon nicht vom Ankerstab gelöst worden, so ist diese Arretiervorrichtung bzw. der entsprechende Teil davon mit dem Ankerstab verbunden, wenn der Ankerstab zwecks Montage durch die genannten Ankerstabbohrungen gesteckt wird. Dieser Teil der Arretiervorrichtung, der vorzugsweise im Rahmen der Montage und Demontage nicht vom Ankerstab gelöst wird, umfasst grundsätzlich das Stellglied. Montage und Demontage können so besonders schnell durchgeführt werden.The part of an anchor system which is pulled out for disassembly of a wall formwork, in addition to the anchor rod basically comprises a locking device or at least a part thereof. For assembly, the anchor rod is inserted into anchor rod holes of closing and setting formwork. Previously, the aforementioned locking device or a part thereof has not been solved by the anchor rod, so this locking device or the corresponding part thereof is connected to the anchor rod when the anchor rod is inserted for the purpose of assembly by said anchor rod holes. This part of the locking device, which is preferably not solved by the anchor rod in the context of assembly and disassembly, basically includes the actuator. Assembly and disassembly can be carried out very quickly.
Eine jede Arretiervorrichtung liegt im montierten Zustand an der Rückseite einer Wandschalung für eine Aufnahme von Kräften an. Die Arretiervorrichtung, die mit dem hindurchgesteckten Ende des Ankerstabs verbunden wird, ist bevorzugt an der Rückseite einer Stellschalung angebracht. Die andere Arretiervorrichtung, die insgesamt oder zum Teil zusammen mit dem Ankerstab zwecks Demontage von den Wandschalungen gelöst wird, ist vorzugsweise an der Rückseite einer Schließschalung vorgesehen, um eine Demontage zu optimieren.Each locking device is in the assembled state at the back of a wall formwork for receiving forces. The locking device, which is connected to the inserted end of the anchor rod, is preferably attached to the back of a setting formwork. The other locking device, which is dissolved in whole or in part together with the anchor rod for the purpose of disassembly of the wall formworks, is preferably provided on the back of a shuttering to optimize disassembly.
In einer vorteilhaften Ausgestaltung wird eine jede Arretiervorrichtung an der Rückseite einer Wandschalung befestigt, so zum Beispiel mittels einer Schraube, damit das Ankersystem sowohl Druckkräfte als auch Zugkräfte aufzunehmen vermag. Eine Arretiervorrichtung kann fest mit dem Ankerstab verbunden sein. Vorteilhaft ist eine jede Arretiervorrichtung jedoch lösbar mit dem Ankerstab verbunden und zwar insbesondere mit Hilfe einer Schraubverbindung, um wirksame Längen des Ankerstabs optimieren zu können.In an advantageous embodiment, each locking device is attached to the back of a wall formwork, so for example by means of a screw, so that the anchor system both compressive forces and Can absorb tensile forces. A locking device can be firmly connected to the anchor rod. Advantageously, however, each locking device is releasably connected to the anchor rod and in particular by means of a screw connection in order to optimize effective lengths of the anchor rod can.
Eine Arretiervorrichtung vorzugsweise jede Arretiervorrichtung des Ankersystems können also vorzugsweise vom Ankerstab gelöst werden und/oder in unterschiedlichen Positionen an jeweils einem Ende des Ankerstabs befestigt werden, so zum Beispiel durch Schrauben, um wirksame Längen des Ankerstabs zu optimieren. Vorzugsweise weist eine jede Arretiervorrichtung eine Befestigungseinrichtung für ein Befestigen der Arretiervorrichtung an einer Wandschalung auf. Die Befestigungseinrichtung umfasst insbesondere eine Schraube, mit der eine Arretiervorrichtung an einem stützenden Element einer Wandschalung festgeschraubt werden kann.A locking device, preferably each locking device of the anchor system can thus be preferably detached from the anchor rod and / or fixed in different positions at one end of the anchor rod, so for example by screws to optimize effective lengths of the anchor rod. Preferably, each locking device has a fastening device for fastening the locking device to a wall formwork. The fastening device comprises in particular a screw with which a locking device can be screwed to a supporting element of a wall formwork.
Grundsätzlich umfasst zumindest eine, vorzugsweise beide Arretiervorrichtungen eine zumindest bereichsweise ebene, insbesondere durch eine Kalottenplatte bereitgestellte Unterseite, die im montierten Zustand an der Wandschalung bzw. an einem stützenden Element der Wandschalung flächig anliegt. Mit der Kalottenplatte ist vorzugsweise beweglich ein Gewinde verbunden, welches mit einem Ankerstabende verschraubt werden kann. Das Gewinde kann vorzugsweise Joystick ähnlich relativ zur Kalottenplatte bewegt werden.Basically, at least one, preferably both locking devices comprises an at least partially planar, in particular provided by a dome plate underside, which rests flat in the assembled state of the wall formwork or on a supporting element of the wall formwork. The dome plate is preferably movably connected to a thread, which can be bolted to an anchor rod end. The thread may preferably be moved in a manner similar to the calotte plate.
In einer Ausführungsform der Erfindung ist das Gewinde der Arretiervorrichtung drehfest an der Kalottenplatte angebracht. Durch diese Ausführungsform wird erreicht, dass ein in Wandschalungen hineingestecktes Ende eines Ankerstabes in das Gewinde hineingedreht werden kann, ohne dass das Gewinde sich unerwünscht mitdreht. Es handelt sich dabei insbesondere um die Arretiervorrichtung, die an der Rückseite einer Wandschalung, insbesondere der Stellschalung vormontiert, d. h. befestigt werden soll, um im Anschluss daran ein durch Schließ- und Stellschalung hindurch gestecktes Ende eines Ankerstabs mit dieser Arretiervorrichtung zu verbinden, insbesondere zu verschrauben.In one embodiment of the invention, the thread of the locking device is non-rotatably mounted on the dome plate. By this embodiment it is achieved that an inserted into wall formworks end of an anchor rod can be screwed into the thread without the thread rotates undesirable. These are in particular the locking device, which is on the back of a wall formwork, in particular the setting formwork preassembled, that is to be fastened, in order to subsequently connect an end of an anchor rod inserted through closing and setting formwork with this locking device, in particular to screw it.
Ein stützendes Element einer Wandschalung besteht grundsätzlich aus einem metallischen Hohlprofil, insbesondere einem Profil mit einem rechteckigen, quadratischen Querschnitt oder hutförmigen Querschnitt. Wände eines solchen Profils sind mit ein oder mehreren Ankerstabbohrungen für ein Hindurchstecken eines Ankerstabs versehen, die auch durch die Schalhaut der Wandschalung hindurchführt.A supporting element of a wall formwork basically consists of a metallic hollow profile, in particular a profile with a rectangular, square cross-section or hat-shaped cross-section. Walls of such a profile are provided with one or more anchor rod holes for passing an anchor rod which also passes through the formwork skin of the wall formwork.
Bevorzugt wird die Arretiervorrichtung an einem stützenden Element befestigt, welches im aufgestellten vertikal verläuft, um so insbesondere entlang der gesamten Höhe einer Stellschalung an einer besonders geeigneten Stelle verankern zu können.Preferably, the locking device is attached to a supporting element which extends vertically in the set up, so as to be able to anchor in particular at a particularly suitable location along the entire height of a setting formwork.
Bevorzugt wird eine Arretiervorrichtung zu Beginn einer Montage auf der Rückseite einer Stellschalung befestigt, da dies die Geschwindigkeit einer Montage maximiert. Nach dem Aufstellen der Schließschalung befindet sich ein Monteur auf der Seite der Schließschalung. Er kann dann also sofort Ankerstäbe montieren.Preferably, a locking device is attached to the beginning of a mounting on the back of a setting formwork, as this maximizes the speed of assembly. After setting up the shuttering, a mechanic is on the side of the shuttering. He can then install anchor rods immediately.
In einer Ausgestaltung der Montage weist das eine Ende des Ankerstabs eine Mehrzahl von Nuten oder Bohrungen auf, die das Rastermaß bilden. Auf dieses Ende ist eine Stellmutter aufgeschraubt. Die Stellmutter hält eine Kontermutter und zwar insbesondere durch einen Flansch. Durch das Halten wird erreicht, dass die Kontermutter abschließend so auf ein Gewinde aufgeschraubt werden kann, dass die Schalung, die mit diesem Gewinde verbunden ist, in die gewünschte Stellung bewegt wird. Ein Anschlag wird so in eine der Nuten oder Bohrungen hineingeschoben oder daran angebracht, dass der Anschlag nicht entlang der Längsachse des Ankers verschoben werden kann. Die Stellmutter wird durch Schrauben in Richtung Anschlag bewegt, bis diese den Anschlag erreicht und fixiert. Das Fixieren kann durch Reibschluss bzw. Kraftschluss erreicht werden. Bevorzugt erfolgt das Fixieren jedoch alternativ oder ergänzend durch Formschluss. Durch das Fixieren wird erreicht, dass der Anschlag nicht aus seiner Stellung herausfallen kann. Durch das Erreichen und Fixieren des Anschlags wird weiter erreicht, dass einfach und zuverlässig die gewünschte Position aufgefunden wird, die für die Herstellung einer gewünschten Wandstärke zu erreichen ist. Im Anschluss daran wird die Kontermutter auf ein Gewinde aufgeschraubt, welches mit der Rückseite der angrenzenden Schalung verbunden ist. Diese Schalung wird so in die gewünschte Stellung bewegt, um eine Wand mit gewünschter Wandstärke herstellen zu können.In one embodiment of the assembly, the one end of the anchor rod on a plurality of grooves or holes, which form the grid. On this end an adjusting nut is screwed. The adjusting nut holds a lock nut, in particular by a flange. By holding it is achieved that the lock nut can finally be screwed onto a thread that the formwork, which is connected to this thread, is moved to the desired position. A stop is pushed into one of the grooves or holes or attached to the fact that the Stop can not be moved along the longitudinal axis of the armature. The adjusting nut is moved in the direction of the stop by means of screws until it reaches and fixes the stop. The fixing can be achieved by friction or adhesion. However, the fixing is preferably carried out alternatively or additionally by positive locking. Fixing ensures that the stop can not fall out of its position. By reaching and fixing the stop is further achieved that simply and reliably the desired position is found, which can be achieved for the production of a desired wall thickness. Subsequently, the lock nut is screwed onto a thread, which is connected to the back of the adjacent formwork. This formwork is moved to the desired position in order to produce a wall with the desired wall thickness can.
Bei dieser Ausführungsform befinden sich Kontermutter und Stellmutter insbesondere zwischen dem Anschlag und der daran angrenzenden Schalung.In this embodiment, lock nut and adjusting nut are in particular between the stop and the adjacent formwork.
Um den Anschlag durch Formschluss zu fixieren, weist der Anschlag bevorzugt eine Ausnehmung auf, in die die Stellmutter mit einem Abschnitt durch Schrauben hinein bewegt werden kann. Befindet sich dieser Abschnitt der Stellmutter in der Ausnehmung des Anschlags, so kann der Anschlag nicht mehr von der Nut oder Bohrung gelöst werden. Alternativ kann aber auch die Stellmutter eine Ausnehmung aufweisen, in die ein Teil des Anschlags gelangt, um so zu fixieren. Diese Ausgestaltung ist jedoch konstruktiv etwas aufwändiger.In order to fix the stop by positive engagement, the stop preferably has a recess into which the adjusting nut can be moved with a section by means of screws. If this section of the adjusting nut is in the recess of the stopper, the stop can no longer be released from the groove or bore. Alternatively, however, the adjusting nut may also have a recess into which a part of the stopper arrives so as to fix it. However, this design is structurally a little more complex.
Ein zur Durchführung des Verfahrens geeignetes Ankersystem umfasst einen Ankerstab und wenigstens eine Arretiervorrichtung. Ein Ende des Ankerstabs umfasst ein Rastermaß, welches insbesondere durch Nuten und/ oder Bohrungen gebildet wird. Für dieses Ende des Ankerstabs ist insbesondere ein Anschlag, eine Stellmutter und eine Kontermutter vorgesehen. Das System umfasst ferner insbesondere ein Gewinde, auf welches die Kontermutter aufgeschraubt werden kann. Das Gewinde kann mittelbar oder unmittelbar an der Rückseite einer Schalung befestigt werden. Das Gewinde ist vorzugsweise mit einer Kalottenplatte verbunden. Die Kalottenplatte ist dann vorzugsweise so beschaffen und eingerichtet, dass diese an der Rückseite einer Schalung befestigt werden kann und zwar insbesondere an einem aus Metall bestehenden Träger oder Riegel der Schalung. Bevorzugt umfasst das Ankersystem für jedes Ende des Ankerstabs eine Arretiervorrichtung, die vom Ankerstab gelöst werden kann.An anchor system suitable for carrying out the method comprises an anchor rod and at least one locking device. One end of the anchor rod comprises a grid, which is formed in particular by grooves and / or holes. For this end of the anchor rod is in particular a stop, a lock nut and a lock nut intended. The system further comprises in particular a thread on which the lock nut can be screwed. The thread can be attached directly or indirectly to the back of a formwork. The thread is preferably connected to a dome plate. The dome plate is then preferably such and arranged that it can be attached to the back of a formwork, and in particular on a metal carrier or bolt of the formwork. Preferably, the anchor system for each end of the anchor rod comprises a locking device which can be released from the anchor rod.
In einer Ausführungsform weist die Arretiervorrichtung, die mit dem Ende des Ankerstabs verbunden wird, eine Hülse oder Bohrung auf, durch die der Ankerstab für eine Montage hindurch geschoben werden kann, ohne schrauben zu müssen. Der Ankerstab kann so zwecks Montage besonders schnell mit seinem dafür vorgesehenen Ende durch die beiden Wandschalungen hindurch geschoben werden.In one embodiment, the locking device, which is connected to the end of the anchor rod, a sleeve or bore through which the anchor rod for assembly can be pushed through without having to screw. The anchor rod can be pushed so particularly fast with its designated end through the two wall formworks for the purpose of assembly.
In einer Ausführungsform umfasst die Hülse ein Außengewinde, welches mit einer Kontermutter verschraubt wird, um das nicht durch Wandschalungen hindurch gesteckte Ende des Ankerstabs mit der Hülse zu verbinden. Die Hülse ist wiederum mittelbar oder unmittelbar bevorzugt mit der Rückseite der entsprechenden Wandschalung verbunden. Bevorzugt ist die Hülse mit einer Kalottenplatte so verbunden, dass die Hülse relativ zur Kalottenplatte wie ein Joystick bewegt werden kann, um so die Hülse für eine problemlos Führung des Ankerstabs ausrichten zu können. Die Kalottenplatte ist dann vorzugsweise an der Rückseite der entsprechenden Wandschalung und zwar in der Regel an der Rückseite einer Schließschalung befestigt und zwar vorzugsweise mittels einer Schraubverbindung, um so schnell, einfach und zuverlässig montieren zu können.In one embodiment, the sleeve comprises an external thread, which is screwed with a lock nut, in order to connect the end of the anchor rod not inserted through wall formworks with the sleeve. The sleeve is in turn indirectly or directly preferably connected to the back of the corresponding wall formwork. Preferably, the sleeve is connected to a dome plate so that the sleeve can be moved relative to the dome plate as a joystick so as to align the sleeve for easy guidance of the anchor rod can. The dome plate is then preferably attached to the back of the corresponding wall formwork and that is usually attached to the back of a closing formwork, preferably by means of a screw, in order to assemble so fast, easy and reliable.
In einer Ausführungsform umfasst die Arretiervorrichtung ein Stellglied, vorzugsweise eine Stellmutter, die auf das nicht hindurch gesteckte Ende des Ankerstabs aufgeschraubt ist. Das Stellglied wird gemäß Rastermaß eingestellt und zwar vorzugsweise durch Verschrauben der Stellmutter bis zum vorgesehenen Rastermaß. Besonders bevorzugt gibt es einen Anschlag, der gemäß Rastermaß positioniert werden kann. In Richtung Anschlag wird dann die Stellmutter geschraubt, bis der Anschlag ein weiteres Schrauben verhindert. Der Ankerstab wird dann durch Schließschalung und Stellschalung hindurchgesteckt und mit der Arretiervorrichtung an der entsprechenden hinteren Wandschalung verbunden. Die hintere Wandschalung ist grundsätzlich die Stellschalung. Nun wird die mit der Stellmutter geeignet verbundene Kontermutter auf das Außengewinde der Hülse geschraubt und zwar vorzugsweise in maximal möglicher Weise. Hierdurch wird nun die entsprechende Wandschalung, bei der es sich bevorzugt um eine Schließschalung handelt, exakt ausgerichtet.In one embodiment, the locking device comprises an actuator, preferably an adjusting nut, which is screwed onto the not inserted end of the anchor rod. The actuator is adjusted according to grid size, preferably by screwing the adjusting nut to the intended grid. Particularly preferably, there is a stop that can be positioned according to grid. The adjusting nut is then screwed in the direction of the stop until the stop prevents further screwing. The anchor rod is then inserted through closing formwork and shuttering and connected to the locking device on the corresponding rear wall formwork. The rear wall formwork is basically the setting formwork. Now, the lock nut suitably connected counter nut is screwed onto the external thread of the sleeve, and preferably in the maximum possible way. As a result, the corresponding wall formwork, which is preferably a closing formwork, is now aligned exactly.
Vorzugsweise weist die Kontermutter Flügel auf, um die Kontermutter zumindest anfänglich schnell verschrauben zu können. Im Bedarfsfall wird die Kontermutter abschließend mithilfe von Werkzeug verschraubt.Preferably, the lock nut has wings in order to screw the lock nut at least initially quickly. If necessary, the lock nut is finally screwed by means of tools.
Als Rastermaß dienen in einer Ausführungsform der Erfindung Nuten im Ankerstab. Insbesondere bei dieser Ausführungsform kann ein Anschlag schnell und zuverlässig gemäß Rastermaß positioniert werden, indem im ausgerichteten Zustand ein Wandbereich des Anschlags in eine entsprechende Nut hineinreicht. Der Anschlag wird dann in seiner vorgesehenen Position so gehalten, dass dieser als Anschlag für ein Stellglied zu dienen vermag.As a grid measure serve in an embodiment of the invention grooves in the anchor rod. In particular, in this embodiment, a stop can be positioned quickly and reliably according to grid dimension by extending in the aligned state, a wall portion of the stopper into a corresponding groove. The stopper is then held in its intended position so that it is able to serve as a stop for an actuator.
Bevorzugt weist der Anschlag eine Öffnung mit einem Bereich auf, der ein schnelles Verschieben entlang des Ankerstabs bis zum Erreichen einer gewünschten Rastermaßposition erlaubt. Vorzugsweise gibt es einen weiteren Bereich, der sich zu einem Ende hin verjüngt, um so den Anschlag stabil in eine Rille bzw. der Nut des Rastermaßes einhängen zu können.The stopper preferably has an opening with a region which allows a rapid displacement along the anchor rod until a desired grid position is reached. Preferably, there is another area that tapers to one end so as to Stable stop to be able to hang in a groove or the groove of the grid.
Damit Stellglied bzw. Stellmutter und Kontermutter besonders gut geeignet miteinander verbunden werden können, umfassen beide Komponenten Flansche, die gegenseitig als Anschlag dienen. Wird die Kontermutter auf die Hülse mit Außengewinde aufgeschraubt, wird der Flansch der Kontermutter gegen den Flansch des Stellglieds bewegt. Kontaktieren sich die beiden Flansche schließlich, so bewirkt ein weiteres Festschrauben der Kontermutter die Ausrichtung der zugehörigen Wandschalung.So that the actuator or adjusting nut and lock nut can be connected to each other particularly well suited, both components include flanges that serve each other as a stop. When the lock nut is screwed onto the externally threaded sleeve, the flange of the lock nut is moved against the actuator's flange. Finally, when the two flanges come into contact with each other, further tightening of the counter nut will cause alignment of the associated wall formwork.
Das Rastermaß weist in einer Ausführungsform Kennzeichnungen auf, die die Dicke von Wänden wiedergeben. Die Kennzeichnungen liegen insbesondere in Form von Zahlenangaben vor, die den zugeordneten Wandstärken bzw. -dicken entsprechen. So zum Beispiel sind in einer Ausführungsform Nuten des Rastermaßes mit derartigen Kennzeichnungen versehen.The grid has, in one embodiment, indicia that represent the thickness of walls. The markings are in particular in the form of numbers that correspond to the assigned wall thicknesses or thicknesses. For example, in one embodiment, grooves of pitch are provided with such markings.
In einer Ausführungsform weist der Anschlag eine Ausnehmung auf, in die ein Teil der Stellmutter im Rahmen einer Montage hineinbewegt werden kann. Durch das Hineinbewegen wird der Anschlag durch Formschluss und damit besonders zuverlässig daran gehindert, sich aus seiner Position zu lösen.In one embodiment, the stop has a recess into which a part of the adjusting nut can be moved during assembly. By moving in, the stop is prevented by positive locking and thus particularly reliable from being released from its position.
Das Ankersystem besteht aus Stabilitätsgründen grundsätzlich aus Metall oder zumindest ganz überwiegend aus Metall.For stability reasons, the anchor system is basically made of metal or at least predominantly of metal.
