Abstract

A formwork system for prefabricated concrete parts has a baseplate (1) on which is mounted a magnet element (2A) which holds formwork or attachment elements in their positions. In order to enable such formwork or attachment elements to be handled more easily, they are equipped with a lifting frame (14) which overlies the magnet element (2A) and, on the side of the magnet element (2A) facing away from the baseplate (1), there is a gap (19) between the magnet element (2A) and the lifting frame (14). A suitably designed spring device (25) in the lifting mechanism can be used, after zeroing, to enable lifting to be carried out automatically.

Description

Die Erfindung betrifft ein Schalungssystem für Betonteile mit einer Grundplatte, auf der ein Magnetkörper aufsetzbar ist, der Schalungs- oder Befestigungsteile an ihrer jeweiligen Position fixiert.The invention relates to a formwork system for concrete parts with a base plate on which a magnetic body is attachable, the formwork or fastening parts fixed at their respective position.

Ein Schalungssystem dieser Art ist aus der DE-A-43 27 696 bekannt. Derartige Schalungssysteme werden in Produktionsanlagen für Betonfertigbauteile eingesetzt. Sie haben den Vorteil, daß an der Grundplatte keine Bohrungen oder ähnliches vorhanden sein müssen, um Schalungen für Betonteile unterschiedlicher Größe auf der gleichen Grundplatte befestigen zu können. Stattdessen wird auf der üblicherweise aus Stahl bestehenden Grundplatte eine Schalung in der gewünschten Größe zusammengestellt und die einzelnen Schalungselemente werden dann über entsprechende Verspann- oder Ankoppelelemente mit Magneten verbunden, die auf der Grundplatte haftend aufgesetzt werden.A formwork system of this type is from DE-A-43 27 696 known. Such formwork systems are in Production plants used for precast concrete components. They have the advantage that there are none on the base plate Bores or the like must be available to Formwork for concrete parts of different sizes to be able to attach the same base plate. Instead is usually made of steel Base plate a formwork put together in the desired size and the individual formwork elements then via appropriate bracing or coupling elements connected with magnets on the base plate stick on.

Ein Schalungssystem wie oben angegeben wurde durch die DE-U-93 00 658 oder DE-U-92 18 032 weitergebildet, indem die Schalungsteile einen den Magneten übergreifenden Abhebebügel aufweisen, wobei auf der der Grundplatte abgewandten Seite des Magnetkörpers ein Spalt zwischen diesem und dem Abhebebügel ist, in den der Magnetkörper einziehbar ist.A formwork system as specified above was designed by DE-U-93 00 658 or DE-U-92 18 032 further developed by the formwork parts overlap the magnets Have lifting handle, being on the base plate opposite side of the magnetic body a gap between this and the lifting handle, in which the magnetic body is retractable.

So kann beim Ausschalen das Schalungsteil zusammen mit dem Magnetkörper von der Grundplatte abgehoben werden, was eine erhebliche Vereinfachung der Ausschalung bedeutet, die jetzt In einem Arbeitsgang erfolgen kann.So the formwork part can be removed together with the magnetic body is lifted off the base plate, which means a considerable simplification of the formwork, which can now be done in one operation.

Demgegenüber war es bisher notwendig, die Schalung und die Magnetkörper separat von der Grundplatte abzunehmen, was einen erheblich größeren Arbeitsaufwand mit sich brachte. Insbesondere kann bei der beschriebenen Ausgestaltung des Schalungssystems die Schalung und die Magnetkörper zusammen zu einer zentralen Reinigungsstation gebracht werden, wo sie für einen erneuten Einsatz gereinigt werden, während bisher für die Magnetkörper jeweils separate Transportmöglichkeiten vorgesehen werden mußten.In contrast, it was previously necessary to formwork and remove the magnetic bodies separately from the base plate, which involves a significantly larger amount of work brought himself. In particular, the described Design of the formwork system, the formwork and the Magnetic body together to form a central cleaning station brought where they are for re-use to be cleaned while previously for the magnetic body separate transportation options are provided had to.

Zur Konstruktion wird in der DE-U-92 18 032 vorgeschlagen, den Magnetkörper mit einer Bohrung zu versehen, in der dann eine sich am Abhebebügel abstützende Hubstange angreift. Über diese Hubstange kann der Magnetkörper betriebssicher in den Abhebebügel eingezogen werden.For construction, DE-U-92 18 032 proposes to provide the magnetic body with a hole in which is then a lifting rod supported on the lifting bracket attacks. The magnetic body can be used with this lifting rod be pulled into the lifting handle in a reliable manner.

Hierbei kann die Hubstange beispielsweise ein Gewinde aufweisen, so daß durch ihre Drehung der Magnetkörper angehoben wird. Dabei kann man dieses Gewinde sowohl mit einer Gewindebohrung am Abhebebügel als auch mit einer Gewindebohrung am Magnetkörper kombinieren. Das zum Verdrehen der Hubstange notwendige Werkzeug in Form eines Schraubenschlüssels ist auf allen Baustellen üblicherweise vorhanden. Here, the lifting rod, for example, a thread have, so that by their rotation of the magnetic body is raised. You can use this thread both with a threaded hole on the lifting bar as well as with combine a threaded hole on the magnet body. The Tools necessary to turn the lifting rod in the form a wrench is on all construction sites usually present.

Das Lösen der Schalungssysteme ist aber relativ schwierig, weil die vollflächig auf der Grundplatte haftenden Magnete nur sehr schwer von dieser wieder zu lösen sind.Solving the formwork systems is relatively difficult, because they adhere to the entire surface of the base plate Magnets are very difficult to remove from this are.

Von daher stellt sich die Aufgabe, ein Schalungssystem wie oben angegeben derart weiterzubilden, daß es auch am Ende seines Gebrauches einfach zu handhaben ist.Hence the task of a formwork system as stated above in such a way that it also easy to use at the end of its use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Abstützung der Hubstange an dem Abhebebügel unter Zwischenschaltung einer Feder erfolgt, die dann insbesondere eine Federkraft aufweist, die geringer ist als die haftkraft des auf die Grundplatte aufgesetzten Magnetkörpers. Bei einer derartigen Ausführungsform wird durch ein leichtes Anheben des Magnetkörpers dieser zumindest einseitig von der Grundplatte abgehoben, wobei die dann noch existierende Anziehungskraft des Magnetkörpers zur Grundplatte erheblich geringer ist als die Haftkraft des flächig auf der Grundplatte aufliegenden Magnetkörpers. Damit kann über die Feder das weitere Abheben des Magnetkörpers von der Grundplatte und sein Einziehen in den Abhebebügel selbsttätig erfolgen.This object is achieved in that the support of the lifting rod on the lifting bracket below Interposition of a spring takes place, which in particular has a spring force that is less than the adhesive force of the placed on the base plate Magnetic body. In such an embodiment by lifting the magnet body slightly this is lifted off the base plate at least on one side, the then remaining attraction of the magnetic body to the base plate considerably lower is as the adhesive force of the flat on the base plate resting magnetic body. So that can about the spring the further lifting of the magnetic body from the base plate and automatically pulling it into the lifting handle respectively.

Bei der Feder kann es sich beispielsweise um eine Schraubenfeder handeln oder um einen Stapel Tellerfedern.The spring can be, for example Act a coil spring or a stack of disc springs.

Es hat sich dabei als vorteilhaft erwiesen, daß der Abhebebügel als integrierter Bestandteil der Schalung ausgeführt wird. Dies ermöglicht eine sehr kompakte Bauform und die Schalung ist daher bei Nichtgebrauch auch besser stapelbar und damit besser zu lagern.It has proven advantageous that the Lifting handle as an integral part of the formwork is performed. This enables a very compact Design and formwork is therefore when not in use also more stackable and therefore easier to store.

Alternativ kann der Abhebebügel auswechselbar an der Schalung befestigt sein. Dies ermöglicht andererseits dessen einfacherer Reinigung. Andererseits kann ein Abhebebügel auch mit verschiedenen Schalungen zusammen eingesetzt werden, wodurch die Kosten der Schalung zu reduzieren sind. Bedenkt man dabei, daß ein Großteil der Schalungen jeweils nur für Eventualfälle auf Lager gehalten werden, kann so eine erheblich geringere Kapitalbindung durch dieses Lager erreicht werden.Alternatively, the lifting bar can be replaced on the Formwork attached. On the other hand, this enables its easier cleaning. On the other hand, a Lifting handle also together with different formwork can be used, which increases the cost of formwork are reducing. Considering that a large part the formwork in each case only for contingency cases can be held, so a significantly lower capital commitment can be reached through this camp.

Dabei ist es günstig, den Abhebebügel mittels einer Adapterführung an der Schalung zu befestigen, die unterschiedliche Schalungshöhen ausgleicht. So kann der gleiche Abhebebügel mit dazugehörigem Magnetkörper eingesetzt werten unabhängig von den übrigen Abmessungen der Schalung.It is convenient to use a lifting handle Attach the adapter guide to the formwork compensates for different formwork heights. So he can same lifting handle with associated magnetic body used values regardless of the other dimensions the formwork.

Die Bedingungen, unter denen die erfindungsgemäße Vorrichtung eingesetzt wird, sind bekanntermaßen stark verschleißend. So können die Einzelteile oft mit flüssigem Beton in Berührung kommen, der sich leicht an ihnen festsetzt, so daß die Teile bei einem Reiben aneinander stark abrasiv beansprucht werden. Unter diesem Aspekt ist es vorteilhaft, daß die wie oben beschrieben am Magnetkörper vorhandene Bohrung für die Hubstange mit einem Gewinde versehen ist, das sich an einem auswechselbaren Abschnitt des Magnetkörpers befindet. Dadurch wird erreicht, daß es gegebenenfalls leicht austauschbar ist, wenn es verschmutzt, verschlissen oder aus sonstigem Grund nicht mehr verwendbar ist.The conditions under which the device according to the invention are known to be strong wearing out. The individual parts can often be liquid Concrete coming into contact with the easily fixes them so that the parts when rubbed are highly abrasive to one another. Under In this aspect, it is advantageous that the as described above Hole on the magnet body for the lifting rod is provided with a thread that is on a replaceable Section of the magnetic body is located. Thereby is achieved that it is easily interchangeable if necessary is when it is dirty, worn out or is no longer usable for any other reason.

Es ist zwar möglich, diesen auswechselbaren Abschnitt mittig am Magnetkörper vorzusehen, vorteilhafterweise werden die Hubstangen aber an den Enden des Magnetkörpers angreifen, da hierdurch besonders günstige Hebel- und Kräfteverhältnisse erreichbar sind.While it is possible to use this interchangeable section to be provided centrally on the magnetic body, advantageously but the lifting rods at the ends of the magnetic body attack, as this results in particularly favorable leverage and power relations are achievable.

Deswegen ist auch der mit Gewinde versehene, auswechselbare Abschnitt am Ende des Magnetkörpers angeordnet, was seine Demontierbarkeit und Austauschbarkeit erleichtert. Dies ist insbesondere dann der Fall, wenn der auswechselbare Abschnitt innerhalb einer U-förmig zur Grundplatte hin offen ausgebildeten Mantelfläche des Magnetkörpers angeordnet ist, aus dem er zum Auswechseln seitlich herausgezogen werden kann. Insbesondere indem im Bereich des auswechselbaren Abschnittes die Schenkel der Mantelfläche zumindest lokal in ihrem lichten Abstand zueinander abnehmen, wird verhindert, daß der auswechselbare Abschnitt unbeabsichtigt nach unten aus dem Magnetkörper herausfallen kann.That's why the threaded, interchangeable one Section arranged at the end of the magnetic body, which facilitates its dismantling and interchangeability. This is especially the case if the interchangeable section within a U-shaped lateral surface open to the base plate the magnetic body is arranged, from which it can be replaced can be pulled out to the side. Especially by in the area of the interchangeable section the legs of the lateral surface at least locally in their decreasing clear distance from each other is prevented that the interchangeable section unintentionally after can fall out of the magnetic body at the bottom.

Indem der auswechselbare Abschnitt dabei auch aus einem Material ist, das vom im Magnetkörper befindlichen Magneten angezogen wird, wird er auch an einem seitlichen Herausfallen gehindert. By the interchangeable section also from one Material is that of the magnet in the magnet body is tightened, it is also on a side Prevented from falling out.

Dabei können aber die vom Magneten auf den auswechselbaren Abschnitt wirkenden Kräfte so groß sein, daß zwischen dem auswechselbaren Abschnitt und dem an diesem im Magnetkörper angrenzenden Magneten eine Fuge vorgesehen ist zum Ansetzen eines Trennwerkzeuges. Mit dem Trennwerkzeug, z. B. einem Schraubenzieher, wird dann der auswechselbare Abschnitt vom Magneten abgehebelt.But it can change from the magnet to the interchangeable one Section forces are so great that between the interchangeable section and the one on it a joint is provided in the magnet body adjacent to the magnet is for attaching a cutting tool. With the Cutting tool, e.g. B. a screwdriver, then the interchangeable section levered off the magnet.

Die angesprochene Bohrung durch den Magnetkörper bzw. durch den auswechselbaren Abschnitt ist vorteilhafterweise eine Durchgangsbohrung, so daß sich in ihr kein Schmutz ansammelt sondern durch diese Bohrung hindurchfällt. Dies hat den Vorteil, daß die über ein Gewinde mit dem Magnetkörper zusammenwirkende Hubstange auch gegen die Grundplatte schraubbar ist und auf diese Art und Weise der Magnetkörper von der Grundplatte abzuheben ist. Dabei wird dann die Hubstange durch den Abhebebügel lediglich geführt.The mentioned hole through the magnetic body or through the interchangeable section is advantageous a through hole, so that there is no Dirt accumulates but falls through this hole. This has the advantage that the thread also interacting with the magnet body can be screwed against the base plate and in this way and way to lift the magnetic body from the base plate is. The lifting rod is then through the lifting bar just led.

Wird dabei der Magnetkörper an nur einem Ende angehoben, ist es vorteilhaft, wenn der Magnetkörper am anderen Ende, mit dem er bei einseitigem Anheben immer noch auf der Grundplatte aufliegt, eine Abrollkante aufweist, um zu verhindern, daß an dieser Auflagestelle eine Punktbelastung der Grundplatte mit hoher hertzscher Pressung auftritt. Bei entsprechender Ausbildung des Schalungssystems, bei dem die beiden erwähnten Enden jeweils mit über Federn am Abhebebügel abgestützten Hubstangen versehen sind, wird auch bei dieser Konstellation erreicht, daß durch das einseitige Anheben des Magnetkörpers die Haftkraft zwischen Magnetkörper und Grundplatte aufgehoben wird und zwischen diesen nur noch die niedrigere Anziehungskraft wirkt, so daß die Federn dann in der Lage sind, den Magnetkörper selbsttätig von der Grundplatte abzuheben.If the magnetic body is lifted at only one end, it is advantageous if the magnetic body on the other End with which he is still lifting on one side rests on the base plate, has a rolling edge, to prevent that at this point a point load on the base plate with high Hertzian Pressing occurs. With appropriate training of the formwork system in which the two ends mentioned each supported by springs on the lifting bar Lifting rods are provided with this constellation achieved that by unilaterally lifting the Magnetic body the adhesive force between the magnetic body and Base plate is lifted and between them only the lower attraction still acts, so that the Springs are then able to move the magnetic body automatically to be lifted off the base plate.

Das heißt, daß der Magnetkörper automatisch in den oben angesprochenen Spalt innerhalb des ihn tunnelartig übergreifenden, im wesentlichen U-förmig auf der Grundplatte aufsitzenden Abhebebügel eingezogen wird, wobei er auch innerhalb des ihn übergreifenden Abhebebügels zu liegen kommt.This means that the magnetic body automatically moves into the above addressed gap within the tunnel like it overlapping, essentially U-shaped on the base plate the lifting handle is pulled in, whereby he also within the crossbar comes to rest.

This lateral surface 3 protrudes the ends 4, 5 of the magnetic body over the inside Magnet 2 out. The outer surface is in these areas provided with holes 6, 7. Under these Holes 6, 7 are interchangeable sections 8, 9, which also have holes that but in contrast to the holes 6, 7 with threads 10, 11 are provided.

Durch die Lochbohrungen 6, 7 und die mit Gewinde 10, 11 versehenen Bohrungen der auswechselbaren Abschnitte 8, 9 hindurch laufen mit Gewinde versehene Hubstangen 12, 13. Diese Hubstangen stützen sich an einem Abhebebügel 14 ab, der integrierter Bestandteil einer Schalung 14A ist.Through the holes 6, 7 and the threaded 10, 11th provided bores of the interchangeable sections 8, 9 threaded lifting rods 12 pass therethrough, 13. These lifting rods are supported on a lifting bracket 14 from, the integral part of a formwork 14A is.

Das bisher mit seinen Elementen beschriebene Schalungssystem funktioniert wie folgt:The formwork system described so far with its elements works as follows:

Um ein (in der Figur 2 rechts von der Schalung 14A liegendes) Betonteil zu fertigen, werden eine Anzahl von Magnetkörpern 2A über ihre Magneten 2 auf die Grundplatte 1 gelegt. Über die derart die Abmessungen des Betonfertigteiles bestimmenden Magnetkörper 2A wird dann die Schalung 14A gesetzt, wobei sich unten an der Schalung 14A befindliche Stege 15, 16 paßgenau seitlich an der Mantelfläche 3 des Magnetkörpers 2A vorbeischieben und damit die Lage der Schalung 14A in bezug auf den Magnetkörper 2A festlegen. Dann werden durch die Schalung 14A bzw. den in diese integrierten Abhebebügel 14 hindurch die Hubstangen 12, 13 hindurchgesteckt, die im hier dargestellten Beispiel als Schrauben mit Sechskantkopf 17, 18 ausgebildet sind. Die Hubstangen 12, 13 werden an ihrem unteren Ende in das Gewinde 10, 11 des dem Magnetkörper 2A zuzurechnenden auswechselbaren Abschnittes 8, 9 eingeschraubt. Dabei wird die Schalung 14A gegen die Grundplatte 1 gezogen. Über einen an dem Sechskantkopf angesetzten Drehmomentschlüssel wird dabei sichergestellt, daß die auf den Magneten 2 durch die Hubstangen 12, 13 ausgeübte Zugkraft nicht höher wird als die Abhebekraft für den Magneten 2.Around a (lying to the right of the formwork 14A in FIG. 2) To manufacture concrete part will be a number of Magnetic bodies 2A via their magnets 2 on the base plate 1 laid. About the dimensions of the Concrete precast magnetic body 2A then the formwork 14A is set, with the bottom of the Formwork 14A webs 15, 16 fit laterally slide past the outer surface 3 of the magnetic body 2A and thus the location of the formwork 14A with respect to set the magnet body 2A. Then through that Formwork 14A or the lifting handle integrated in it 14 inserted through the lifting rods 12, 13, the in the example shown here as screws with hexagon head 17, 18 are formed. The lifting rods 12, 13 are at their lower end in the thread 10, 11 of the the interchangeable portion attributable to the magnetic body 2A 8, 9 screwed in. The formwork 14A pulled against the base plate 1. About one at that Hexagon head attached torque wrench ensured that the on the magnet 2 by the lifting rods 12, 13 exerted tensile force not higher is used as the lifting force for the magnet 2.

Das Betonfertigteil wird dann gegossen. Wenn der Beton des Fertigteiles erstarrt ist, muß die Schalung 14A von der Grundplatte 1 wieder gelöst werden. Hierzu wird eine der Hubstangen, zum Beispiel die Hubstange 13, über das oben angesprochene Drehmoment hinaus angezogen, woraufhin sich das Ende 5 des Magnetkörpers 2A von der Grundplatte 1 hebt und in einen Spalt 19 gezogen wird, der zwischen der der Grundplatte 1 abgewandten Seite des Magnetkörpers 2A und dem Abhebebügel 14 gebildet ist. Bei diesem Abheben am einen Ende schwenkt der Magnetkörper 2A am gegenüberliegenden Ende 4 um eine Abrollkante 20, die dann einen Linienkontakt zwischen dem Magnetkörper 2A und der Grundplatte 1 bildet.The precast concrete is then poured. If the concrete of the finished part is solidified, the formwork 14A of the base plate 1 can be solved again. For this, a the lifting rods, for example the lifting rod 13, over tightened the torque mentioned above, whereupon the end 5 of the magnetic body 2A from the Base plate 1 lifts and is pulled into a gap 19, the between the side facing away from the base plate 1 of the magnetic body 2A and the lifting bracket 14 are formed is. When lifting off at one end, the magnetic body swivels 2A at the opposite end 4 around a rolling edge 20, which then has a line contact between the Magnetic body 2A and the base plate 1 forms.

Nachdem damit der Magnetkörper 2A nicht mehr auf seiner gesamten Fläche Haftkontakt mit der Grundplatte 1 aufweist, wirkt zwischen ihm und der Grundplatte 1 nur noch die magnetische Anziehungskraft, die erheblich niedriger als die vorher herrschende Haftkraft ist. Somit kann der Magnetkörper 2A durch Anheben des noch nicht angehobenen Endes 4 nun leicht völlig von der Grundplatte 1 gelöst werden. Die Schalung 14A kann dann ohne weiteres vom fertigen Betonteil abgezogen werden (in Figur 2 nach links).After the magnetic body 2A is no longer on it entire surface has adhesive contact with the base plate 1, acts between him and the base plate 1 only nor the magnetic attraction, which is significant is lower than the previous adhesive force. Consequently can the magnetic body 2A by lifting the still not raised end 4 now slightly completely from the Base plate 1 can be solved. The formwork 14A can then can be easily removed from the finished concrete part (to the left in Figure 2).

Die Hubstangen 12, 13 werden dann wieder aus den Gewinden 10, 11 der auswechselbaren Abschnitte 8, 9 herausgeschraubt und die Magnetkörper 2A können dann wieder neu verwandt werden. Vorher werden sie üblicherweise aber noch gereinigt.The lifting rods 12, 13 are then again from the threads 10, 11 of the interchangeable sections 8, 9 unscrewed and the magnetic body 2A can then can be used again. Before that, they usually are but still cleaned.

Aufgrund der Umgebungseinflüsse sind die Gewinde 10, 11 in den auswechselbaren Abschnitten starkem Verschleiß ausgesetzt. Das heißt, die Anhebefunktion wie oben beschrieben, ist auf Dauer nicht sichergestellt, da es in den Gewinden leicht zu Fressen kommen kann. Ein Magnetkörper 2A wie hier dargestellt kann aber dann weiterverwandt werden, indem lediglich der auswechselbare Abschnitt 8, 9 entfernt und durch einen neuen ersetzt wird, der ein neues, unverschlissenes Gewinde aufweist.Due to the environmental influences, the threads 10, 11 heavy wear in the interchangeable sections exposed. That is, the lifting function as described above, is not guaranteed in the long run because it is in the threads can easily eat. A magnetic body 2A as shown here can then be used by simply changing the section 8, 9 removed and replaced with a new one that has a new, unworn thread.

Damit ein solcher Abschnitt 8, 9 nicht unbeabsichtigt verloren geht, muß er an dem Magnetkörper 2A befestigt werden. Einerseits geschieht dies dadurch, daß die Mantelfläche 3 im Bereich der auswechselbaren Abschnitte 8, 9 sich nach unten leicht verjüngt, so daß damit der auswechselbare Abschnitt 8, 9 nicht in diese Richtung aus der ansonsten offenen Mantelfläche herausfallen kann. Zur dann noch offenen (in Figur 2 nach vorne liegenden) Seitenfläche ist der auswechselbare Abschnitt 8, 9 durch den Magneten 2 gesichert: Die auswechselbaren Abschnitte 8, 9 bestehen nämlich (insbesondere auch aus Kostengründen) aus einfachem Stahl, der von dem Magneten 2 angezogen wird, womit die auswechselbaren Abschnitte 8, 9 auch in dieser Richtung fixiert sind.So that such a section 8, 9 is not inadvertently lost, it must be attached to the magnetic body 2A become. On the one hand, this happens because the outer surface 3 in the area of interchangeable sections 8, 9 tapers slightly downwards, so that the interchangeable section 8, 9 not in this direction fall out of the otherwise open surface can. To the then still open (lying forward in Figure 2) Side surface is the interchangeable section 8, 9 secured by magnet 2: the replaceable ones Sections 8, 9 exist (in particular also for cost reasons) made of simple steel made by the Magnet 2 is attracted, making the interchangeable Sections 8, 9 are also fixed in this direction.

Um die auswechselbaren Abschnitte 8, 9 aber trotzdem von dem Magneten 2 lösen zu können, sind sie an der Grenzfläche zum Magneten 2 mit einer Fuge 21 versehen, in die ein Trennwerkzeug eingeschoben werden kann.To the interchangeable sections 8, 9 but still To be able to detach from the magnet 2, they are on the Provide interface to magnet 2 with a joint 21, into which a cutting tool can be inserted.

Damit erhält man einen Magnetkörper 2A, der immer wieder verwandt werden kann, wobei dessen verschleißanfällige Gewindeabschnitte 8, 9 einfach auszutauschen sind. Daß dies ein erheblicher Kostenvorteil ist, liegt auf der Hand.This gives you a magnetic body 2A that keeps coming back can be used, its wear-prone Thread sections 8, 9 easy to replace are. That this is a significant cost advantage is obvious On the hand.

Grundsätzlich kann ein derartiger Magnetkörper 2A auch ohne die oben beschriebene Schalung 14 auf einer Grundplatte 1 verwandt werden kann. Dann wird über eine der mit Gewinde 10, 11 versehenen Bohrungen 8, 9 ein bekanntes Verspann- oder Ankoppelelement mit dem Magnetkörper 2A verbunden.In principle, such a magnetic body 2A can also without the formwork 14 described above on a base plate 1 can be used. Then one of the with threads 10, 11 provided holes 8, 9 a known Bracing or coupling element with the magnetic body 2A connected.

Zum entsprechenden Lösen eines solchen Magnetkörpers 2A von der Grundplatte nach dem Gebrauch würde dann beispielsweise eine durch das Gewinde 11 hindurchlaufende Hubstange 13 soweit eingeschraubt, bis sie auf der Grundplatte 1 aufliegt. Bei einem weiteren Einschrauben würde dann das Ende 5 des Magnetkörpers 2A angehoben und wie oben beschrieben um die Abrollkante 20 verschwenkt, so daß der Magnetkörper 2A dann aufgrund der in dieser Stellung nur noch wirkenden, gegenüber der Haftkraft geringeren magnetischen Anziehungskraft leicht von der Grundplatte 1 zu entfernen ist.For the corresponding release of such a magnetic body 2A of the base plate after use would then, for example one passing through the thread 11 Screwed in the lifting rod 13 until it is on the Base plate 1 rests. With another screwing the end 5 of the magnetic body 2A would then be raised and pivoted around the rolling edge 20 as described above, so that the magnetic body 2A due to the only acting in this position, compared to the Lower magnetic attraction is easy to remove from the base plate 1.

In der Figur 3 ist eine Ausführungsform eines erfindungsgemäßen Schalungssystems dargestellt. Dort ist der Abhebebügel 14 in eine Adapterführung 22 paßgenau eingesetzt. Aus dieser Adapterführung 22 ist der Abhebebügel 14 nach oben zu entnehmen. Die Adapterführung 22 ist in eine schraffiert dargestellte H-förmig ausgebildete Schalung 23 integriert, wobei durch eine gestrichelt dargestellte Kontur 24 zu erkennen ist, das eine Adapterführung 22 bei H-förmigem Schalungen 23 unterschiedlicher Größe verwandt werden können, wobei sie jeweils unterschiedlich tief aber immer mit der gleichen Höhe über der Grundplatte 1 in die Schalung integriert wird.FIG. 3 shows an embodiment of an inventive one Formwork system shown. There is the Lifting bar 14 inserted into an adapter guide 22 with a precise fit. The lifting handle is from this adapter guide 22 14 upwards. The adapter guide 22 is formed into an H-shaped hatching Formwork 23 integrated, with a dashed shown contour 24 can be seen, the one Adapter guide 22 with H-shaped formwork 23 different Size can be used taking it different depths but always the same Height above the base plate 1 integrated in the formwork becomes.

Im übrigen ist in Figur 3 zu erkennen, daß die Hubstangen 12 sich über Federn 25 in Form eines Paketes Tellerfedern an dem Abhebebügel 14 abstützen. Bei abgehobenen Zustand des Abhebebügels von der Grundplatte 1, wie in Figur 3 dargestellt, sind diese Federn entspannt.Otherwise, FIG to recognize that the lifting rods 12 over springs 25th in the form of a package of disc springs on the lifting handle Support 14. When the lifting handle is lifted off of the base plate 1, as shown in Figure 3, are these feathers relaxed.

Wird, wie in Figur 4 dargestellt, der Magnetkörper 2A auf die Grundplatte 1 aufgesetzt, sind die Federn 25, über die sich die Hubstangen 12 und 13 am Abhebebügel 14 abstützen, gespannt. Dabei ist die Spannkraft dieser Federn 25 geringer als die Haftkraft des Magnetkörpers 2A an der Grundplatte 1. As shown in FIG. 4, the magnetic body 2A placed on the base plate 1, the springs 25, over which the lifting rods 12 and 13 on the lifting bar Support 14, excited. The resilience is this Springs 25 less than the adhesive force of the magnetic body 2A on the base plate 1.

In der Figur 5 ist in den Zeichnungen a) bis c) hierzu dargestellt, wie das Lösen dieses Magnetkörpers 2A von der Grundplatte 1 erfolgt. Mit einem entsprechenden Hebel 26, der unter einer entsprechenden Scheibe 27 angesetzt wird, wird eine der beiden Hubstangen 12, 13 angehoben, wodurch der auf der Grundplatte 1 flächig aufliegende Magnetkörper 2A einseitig angehoben wird. Dabei entsteht ein keilförmiger Spalt 28 zwischen der Unterseite des Magnetkörpers 2A und der Grundplatte 1. Gleichzeitig wird durch diesen Spalt 28 bewirkt, daß der Magnet 2 nicht mehr mit seiner vollen Haftkraft an der Grundplatte 1 haftet sondern zwischen diesen nur noch eine geringere magnetische Anziehungskraft wirkt. Dies hat zur Folge, daß an der anderen Hubstange 13 die entsprechende Feder 25 die Hubstange 13 ebenfalls nach oben ziehen kann, womit der Magnetkörper 2A, wie in der Figur 5c) dargestellt, vollständig von der Grundplatte 1 abgehoben wird.5 shows a) to c) in the drawings shown how to detach this magnetic body 2A from the base plate 1 takes place. With an appropriate lever 26, which is placed under a corresponding disc 27 one of the two lifting rods 12, 13 is raised, whereby the surface lying on the base plate 1 Magnetic body 2A is lifted on one side. Here there is a wedge-shaped gap 28 between the underside of the magnetic body 2A and the base plate 1. At the same time, this gap 28 causes the magnet 2 no longer with its full adhesive force the base plate 1 but only adheres between them even less magnetic attraction. This has the consequence that on the other lifting rod 13 corresponding spring 25 also the lifting rod 13 after can pull up, with which the magnetic body 2A, as in the Figure 5c) shown completely from the base plate 1 is lifted off.

Damit kann die Schalung wie oben beschrieben abgenommen und nach einer entsprechenden Reinigung wieder neu eingesetzt werden.The formwork can then be removed as described above and after a corresponding cleaning again be used.

Gegebenenfalls wird die Schalung 14A aber auch bis zu einer erneuten Benutzung eingelagert. Dann wird der Magnetkörper 2A mit dem dazugehörigen Abhebebügel 14 aus der entsprechenden Adapterführung 22 der Schalung 14A entnommen und in eine andere Adapterführung einer anderen Schalung eingesetzt.
Durch ein gleichzeitiges nach unten drücken der beiden Hubstangen 12, 13 wird im entgegengesetzten Fall bewirkt, daß der Magnetkörper 2A flächig auf die Bodenplatte 1 zu liegen kommt und damit fest an der Grundplatte 1 haftet und somit eine feste Verankerung der Schalung 14A auf der Grundplatte 1 bewirken kann.If necessary, the formwork 14A is also stored until it is used again. Then the magnetic body 2A with the associated lifting bracket 14 is removed from the corresponding adapter guide 22 of the formwork 14A and inserted into another adapter guide of another formwork.
In the opposite case, pressing the two lifting rods 12, 13 simultaneously downwards causes the magnetic body 2A to lie flat on the base plate 1 and thus firmly adhere to the base plate 1 and thus firmly anchor the formwork 14A to the base plate 1 can effect.
