Definitions
- the present invention relates to an arrangement comprising a formwork element for a finished component to be produced on a formwork support and a holding element for attaching the formwork element to the formwork support suitable for the production of prefabricated elements, in particular in the form of a pallet, wherein the retaining element from above into a recess of the formwork element is insertable and removable, wherein the holding element comprises a magnet and the holding element holds the formwork element on the formwork support. Furthermore, the invention relates to a method for producing a finished component and a method for attaching a formwork element by at least one holding element on a formwork support for prefabricated components.
- Formwork overlays with formwork elements for the manufacture of prefabricated concrete components have long been known.
- To produce prefabricated components in various sizes and shapes, different lengths and shapes of formwork elements are required.
- In general, there are standardized formwork elements with certain lengths which, by arranging on the formwork support, form a receiving space between these formwork elements, into which concrete is poured in, for example by casting. to obtain a rectangular prefabricated component.
- One way of attaching these standardized formwork elements, which usually consist of a metal, is given by providing magnets in the standardized formwork elements.
- a formwork system for precast concrete out goes from the DE 299 20 866 U1 1999, a formwork system for precast concrete out.
- a magnetic body with its underside on a base plate can be placed, whereby formwork parts are fixed in their respective position.
- Between the base plate and the formwork part of the magnetic body is retractable or liftable by a lifting element.
- the magnetic body and the lifting element can not be removed from the formwork part.
- the German patent application DE 101 10 224 A1 from 2001 shows a formwork system for shuttering precast concrete elements.
- the formwork body is designed as a U-profile, within which a magnet is arranged, which is directly connected by an opening in the formwork body with a shift knob. Through this shift knob, the magnet can be switched. Again, it is not stated that the magnet and shift knob can be solved by the formwork element.
- formwork elements containing integrated magnets are sequentially placed on a pallet by a robot with automatic control.
- a formwork element is first brought into a pre-position in which it is in the raised state and at a distance from the previous formwork element.
- the formwork element is either stepped or diagonally moved to the target position in which it rests against an adjacent formwork element.
- Such a gun with cartridges is also subject to constant temperature fluctuations during refilling.
- guns with granulate feed are in use, which, however, have a high purchase price.
- severe pollution of the workplace occurs due to unavoidable stringing and dripping of the adhesive. This is especially the risk of skin burns.
- Another problem is that if the sheet steel surface is oily, the adhesive will not adhere and thus cleaning will be needed prior to the attachment of the formwork elements. Even if the surface is clean, the adhesion of the adhesive can be a problem if it is too cold. Once the glue is too warm, the polystyrene melts and the glue disappears inside the styrofoam. Thus only pistols with temperature control can be used.
- the adhesive must have different temperatures. When the adhesive adheres optimally to the formwork surface, the problem then arises during cleaning that the pallets must be cleaned by hand from the adhesive residue, since otherwise prints are produced in the subsequently manufactured finished concrete element.
- the object of the invention is therefore to provide a holding element of the type mentioned, with which the known from the prior art problems can be avoided and which in particular represents a simple way to attach formwork elements on shuttering pallets.
- the holding elements are reusable and suitable for each type of formwork elements with corresponding recesses.
- the formwork elements can be cut into the desired shapes and are magnetically held by the insertable and removable retaining element on the metallic formwork support.
- the holding element has a head part and a foot part, wherein the magnet is permanently connected to the holding element, preferably with its foot part and the foot part of the holding element protrudes into a recess of the formwork element.
- the head part on the formwork element preferably protrude vertically.
- the foot part substantially corresponds to the recess of the shuttering element.
- An embodiment provides that the head part of the holding element has a larger diameter than the foot part of the holding element.
- the holding element has a mushroom shape.
- the head part of the holding element has a larger diameter than the recess of the formwork element.
- An advantageous embodiment of the holding element provides that the holding element passes by moving in the direction of the formwork support in a fixing position for formwork support, in which the holding element together with the formwork element is magnetically fixed to the formwork support.
- the detachment of the holding elements can either be done manually by means of a removal tool or be performed automatically via a robot.
- An inventive embodiment of the present invention provides that between the holding element and formwork element, a compressible spacer is arranged. Furthermore, it can be provided that the compressible spacer holds the holding element at a distance from the formwork support, wherein the holding element at a distance not yet fixed the formwork element to the formwork support. As a result, the holding element is held in a position spaced from the formwork support or raised position, in which the magnet is not yet attracted to the formwork support or is not yet sufficiently attracted to overcome the resistance by the compressible spacer. This distance can be a few millimeters to a few centimeters, but this depends greatly on the magnets used and on the dimensions of the prefabricated components to be manufactured and the necessary formwork elements and retaining elements.
- the formwork element can be moved to the formwork support in the desired position. After positioning the formwork elements to the desired positions can be provided that the holding element inserted into the formwork element passes by moving the holding element in the direction of the formwork support under compression of the spacer in a fixing position for formwork support and holds the formwork element magnetically on the formwork support.
- One embodiment provides that the movement of the holding element is carried out by pressing by a shuttering robot.
- the compressible spacer is designed as a spring, which is arranged between the head part of the holding element and the formwork element. This spring distanced the entire holding element from the formwork support in such a way that a position in which sufficient magnetic force is not yet present is held for fixing the holding element.
- this spacer provides that the compressible spacer is formed by an at least partially compressible portion of the formwork element itself.
- the recess or the formwork element is cut in such a way that the holding element can not even reach the fixing position with an underlying formwork support when being introduced into the formwork element.
- the compressible spacer in the formwork element is compressible by a preferably wedge-shaped, directed towards formwork element projection on the head part of the holding element.
- the extension of the holding element in fixing position penetrates into the, preferably soft material existing formwork element or this compressed.
- the material of the formwork element for example Styrofoam or wood, is intended to be depressible so far that the existing before the impressions of the holding element distance between the underside of the holding element and formwork support in or in the formwork element can be pressed. In a preferred embodiment, this distance is about 3 mm.
- the retaining element is at least one or at least two recesses are provided. If the holding element is designed, for example, rotationally symmetrical, only such a holding element could offer no rotationally fixed fixation of the formwork element. For this purpose, then two retaining elements would have to be provided in two recesses of the formwork element. If the holding element is not rotationally symmetrical, a rotation of the formwork element to the holding element is not possible, whereby a fixation with only one holding element is made possible.
- the at least one recess is designed as a substantially vertical through hole through the formwork element.
- the formwork element consists of metal, for example steel, polystyrene, wood or the like.
- Protection is also desired for a method for attaching a formwork element by at least one holding element on a formwork support for prefabricated elements according to the teaching of claim 13, wherein in a first step, the positioning of a formwork element with at least one introduced into a recess of the formwork element, a magnet having holding member on the formwork support, and in a second step, the movement of the holding element in a fixing position for shuttering, in which the holding element together with shuttering element is magnetically fixed to the formwork support, is provided.
- a particular embodiment provides that when moving the retaining element used in a formwork element in the direction of formwork support the formwork element is fixed under compression of a spacer on the formwork support.
- a further embodiment provides that the attachment of the at least one formwork element by at least one holding element on a formwork support for prefabricated components using a shuttering robot takes place.
- the formwork robot performs at least one step of this process, while other steps can also be done manually.
- protection is sought for a method for producing a prefabricated component on a formwork support, wherein in a first step, the positioning of a formwork element with at least one introduced into a recess of the formwork element, a magnet-containing holding element on the formwork support, in a second step, the movement of the holding element in a fixing position to the formwork support, in which the holding element together with the formwork element is magnetically fixed to the formwork support, in a third step, the manufacture of a finished component by pouring a curable material, preferably concrete, in at least one space between formwork elements, and in a fourth step, the removal the holding elements of the formwork elements and removing the formwork elements is provided by the formwork support.
- a curable material preferably concrete
- One embodiment variant provides that the production of a finished component takes place on a formwork support using a formwork robot or demoulding robot. In this case, at least one method step should be performed by the shuttering robot.
- these steps can be performed by a shuttering robot or entirely by hand these steps.
- the blank of the individual formwork elements can be automated. These cuts can be made in 90 ° angles, mitred or else with curves or other shapes.
- the general forms can first be positioned by means of standardized formwork elements in order subsequently to adapt the cut formwork elements or special formwork elements. This so-called residual formwork is prepared in such a way that the formwork can be cast on both sides. After introducing the retaining elements into the recesses of the formwork elements can be done by pressing the retaining elements in the activated position fixation.

- Fig. 3a shows a cross section of a formwork element 2, which rests on the formwork support and has a recess 4.
- the holding element 1 is inserted into this recess 4 while maintaining a distance A. In this position, no sufficient magnetic force is present to pull the entire holding element 1 to the formwork support 3.

- Fig. 4c is now the retaining element 1 in the fixing position, wherein the spring 6a is compressed. In order to hold the retaining element 1 in this fixing position, the attraction between magnet 5 and shuttering pad 3 must be greater than the spring force of the spring 6a.
- the shuttering element 2 is preferably made of a soft, in particular deformable material (eg Styrofoam).
- the formwork element is preferably made of a hard material (eg metal).
- Fig. 5 is a formwork element 2 shown with recess 4 and below architectureerndem base.

Die vorliegende Erfindung betrifft eine Anordnung, mit einem Schalungselement für ein auf einer Schalungsauflage herzustellendes Fertigbauelement und einem Halteelement zum Anbringen des Schalungselementes auf der für die Herstellung von Fertigbauelementen geeigneten Schalungsauflage, insbesondere in Form einer Palette, wobei das Halteelement von oben in eine Ausnehmung des Schalungselementes einführbar und entnehmbar ist, wobei das Halteelement einen Magnet aufweist und das Halteelement das Schalungselement an der Schalungsauflage hält. Weiters betrifft die Erfindung ein Verfahren zum Herstellen eines Fertigbauelementes und ein Verfahren zum Anbringen eines Schalungselementes durch zumindest ein Halteelement auf einer Schalungsauflage für Fertigbauelemente.The present invention relates to an arrangement comprising a formwork element for a finished component to be produced on a formwork support and a holding element for attaching the formwork element to the formwork support suitable for the production of prefabricated elements, in particular in the form of a pallet, wherein the retaining element from above into a recess of the formwork element is insertable and removable, wherein the holding element comprises a magnet and the holding element holds the formwork element on the formwork support. Furthermore, the invention relates to a method for producing a finished component and a method for attaching a formwork element by at least one holding element on a formwork support for prefabricated components.
Schalungsauflagen mit Schalungselementen zum Herstellen von Fertigbetonbauteilen sind schon lange bekannt. Um nun Fertigbauelemente in verschiedenen Größen und Formen herzustellen, sind unterschiedliche Längen und Formen von Schalungselementen erforderlich. Generell gibt es standardisierte Schalungselemente mit bestimmten Längen die durch Anordnen auf der Schalungsauflage einen Aufnahmeraum zwischen diesen Schalungselementen bilden, in welchen Beton eingegossen wird um z.B. ein rechteckiges Fertigbauelement zu erhalten. Eine Möglichkeit der Anbringung dieser standardisierten Schalungselemente, die meist aus einem Metall bestehen, ist durch Vorsehen von Magneten in den standardisierten Schalungselementen gegeben.Formwork overlays with formwork elements for the manufacture of prefabricated concrete components have long been known. To produce prefabricated components in various sizes and shapes, different lengths and shapes of formwork elements are required. In general, there are standardized formwork elements with certain lengths which, by arranging on the formwork support, form a receiving space between these formwork elements, into which concrete is poured in, for example by casting. to obtain a rectangular prefabricated component. One way of attaching these standardized formwork elements, which usually consist of a metal, is given by providing magnets in the standardized formwork elements.

Ein weiteres Beispiel ist in der Deutschen Patentschrift
Wenn nun aber unregelmäßige Fertigbauelemente gefertigt werden, sind einzeln zugeschnittene Schalungselement besonders für die unregelmäßigen Bereiche des Fertigbauelementes notwendig. Hierzu können die standardisierten Schalungselemente nicht verwendet werden, sondern müssten zugeschnitten werden. Dies ist bei metallischen Schalungselementen allerdings sehr aufwändig und darüber hinaus unwirtschaftlich. Deshalb werden vor allem für die Herstellung von zugeschnittenen Schalungselementen andere Materialien, die leicht zugeschnitten werden können und auch keinen hohen Materialpreis aufweisen, verwendet. Vor allem Schalungselemente aus Holz und Styropor sind dafür gängige Materialien, jedoch ist das Fixieren bzw. Anbringen dieser Schalungselemente auf der Schalungsauflage mit Problemen verbunden. Eine gängige Lösung hierzu ist das Aufkleben dieser extra zugeschnittenen Schalungselemente, wobei zahlreiche Probleme auftreten. Das Aufkleben kann beispielsweise mittels einer Heißklebepistole durchgeführt werden, die allerdings sehr teuer im Einkauf ist und eine kurze Lebensdauer aufweist. Eine solche Pistole mit Kartuschen unterliegt des Weiteren andauernden Temperaturschwankungen beim Nachfüllen. Auch Pistolen mit Granulatbeschickung sind im Einsatz, welche allerdings einen hohen Anschaffungspreis haben. Darüber hinaus tritt bei Verwendung eines Heißklebers eine starke Verschmutzung des Arbeitsplatzes durch unvermeidliches Fadenziehen und Nachtropfen des Klebers auf. Hierbei besteht besonders die Gefahr von Hautverbrennungen. Ein weiteres Problem besteht darin, dass, wenn die Stahlblechoberfläche ölig ist, der Kleber nicht haftet und dadurch eine Reinigung vor der Anbringung der Schalungselemente nötig ist. Auch wenn die Fläche dann sauber ist, kann die Haftung des Klebers ein Problem sein, wenn dieser zu kalt ist. Ist der Kleber wiederum zu warm, schmilzt das Styropor und der Kleber verschwindet im Inneren des Styropors. Somit können nur Pistolen mit Temperaturüberwachung benutzt werden. Wenn verschiedene Styroporkonsistenzen (10, 20 oder 30 kg/m3) angewendet werden, muss der Kleber verschiedene Temperaturen aufweisen. Wenn der Kleber optimal auf der Schalfläche haftet, tritt anschließend bei der Reinigung das Problem auf, dass die Paletten von Hand vom Klebrückstand nachgereinigt werden müssen, da sonst Abdrücke im darauf folgenden gefertigten Fertigbetonelement entstehen.But if now irregular prefabricated elements are made, individually tailored formwork element are particularly necessary for the irregular areas of the finished component. For this purpose, the standardized formwork elements can not be used, but would have to be tailored. However, this is very complicated in metallic formwork elements and beyond uneconomical. Therefore, especially for the production of tailored formwork elements other materials that can be easily cut and also have no high cost of materials used. Above all formwork elements made of wood and polystyrene are common materials, but the fixing or attachment of these formwork elements on the formwork support is associated with problems. A common solution for this is the gluing of these extra tailored formwork elements, with numerous problems occur. The sticking can be done for example by means of a hot glue gun, which is very expensive to buy and has a short life. Such a gun with cartridges is also subject to constant temperature fluctuations during refilling. Also guns with granulate feed are in use, which, however, have a high purchase price. About that In addition, when using a hot melt adhesive, severe pollution of the workplace occurs due to unavoidable stringing and dripping of the adhesive. This is especially the risk of skin burns. Another problem is that if the sheet steel surface is oily, the adhesive will not adhere and thus cleaning will be needed prior to the attachment of the formwork elements. Even if the surface is clean, the adhesion of the adhesive can be a problem if it is too cold. Once the glue is too warm, the polystyrene melts and the glue disappears inside the styrofoam. Thus only pistols with temperature control can be used. If different styrofoam consistencies (10, 20 or 30 kg / m 3 ) are used, the adhesive must have different temperatures. When the adhesive adheres optimally to the formwork surface, the problem then arises during cleaning that the pallets must be cleaned by hand from the adhesive residue, since otherwise prints are produced in the subsequently manufactured finished concrete element.
Die Aufgabe der Erfindung besteht nun darin, ein Halteelement der eingangs genannten Art zu schaffen, mit dem die aus dem Stand der Technik bekannten Probleme vermieden werden können und welches insbesondere eine einfache Möglichkeit zur Anbringung von Schalungselementen auf Schalungspaletten darstellt.The object of the invention is therefore to provide a holding element of the type mentioned, with which the known from the prior art problems can be avoided and which in particular represents a simple way to attach formwork elements on shuttering pallets.
Diese Aufgabe wird durch eine Anordnung mit den Merkmalen von Anspruch 1 gelöst. Durch die Entnehmbarkeit sind die Halteelemente wieder verwendbar und für jede Art von Schalungselementen mit entsprechenden Ausnehmungen geeignet. Somit können die Schalungselemente in die gewünschten Formen zugeschnitten werden und durch das einführbare und entnehmbare Halteelement an der metallischen Schalungsauflage magnetisch gehalten werden.This object is achieved by an arrangement having the features of
Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass das Halteelement einen Kopfteil und einen Fußteil aufweist, wobei der Magnet dauerhaft mit dem Halteelement, vorzugsweise mit dessen Fußteil verbunden ist und der Fußteil des Halteelementes in eine Ausnehmung des Schalungselementes ragt. Dabei kann der Kopfteil über das Schalungselement, vorzugsweise vertikal hinausragen. Weiters kann vorgesehen sein, dass der Fußteil im Wesentlichen der Ausnehmung des Schalungselementes entspricht. Es kann allerdings auch das gesamte Halteelement in seinem Umfang der Ausnehmung des Schalungselementes entsprechen. Ein Ausführungsbeispiel sieht dabei vor, dass der Kopfteil des Halteelements einen größeren Durchmesser als der Fußteil des Halteelementes aufweist. Somit hat das Halteelement eine Pilzform. Weiters kann vorgesehen sein, dass der Kopfteil des Halteelementes einen größeren Durchmesser als die Ausnehmung des Schalungselementes aufweist.According to one embodiment, it may be provided that the holding element has a head part and a foot part, wherein the magnet is permanently connected to the holding element, preferably with its foot part and the foot part of the holding element protrudes into a recess of the formwork element. In this case, the head part on the formwork element, preferably protrude vertically. Furthermore, it can be provided that the foot part substantially corresponds to the recess of the shuttering element. However, it can also be the entire holding element in correspond to its circumference of the recess of the formwork element. An embodiment provides that the head part of the holding element has a larger diameter than the foot part of the holding element. Thus, the holding element has a mushroom shape. Furthermore, it can be provided that the head part of the holding element has a larger diameter than the recess of the formwork element.
Eine vorteilhafte Ausführung des Halteelementes sieht vor, dass das Halteelement durch Bewegen in Richtung Schalungsauflage in eine Fixierposition zur Schalungsauflage gelangt, in der das Halteelement samt Schalungselement magnetisch an der Schalungsauflage fixiert ist. Das Ablösen der Halteelemente kann entweder mittels eines Ablösewerkzeuges manuell getätigt werden oder aber auch automatisch über einen Roboter ausgeführt werden. Durch diese Ausführung ist eine einfache Lösbarkeit des Schalungselementes mitsamt dem Halteelement von der Schalungsauflage gegeben und es bleiben keine Rückstände, wie beispielsweise Heißkleber auf der Schalungsauflage zurück.An advantageous embodiment of the holding element provides that the holding element passes by moving in the direction of the formwork support in a fixing position for formwork support, in which the holding element together with the formwork element is magnetically fixed to the formwork support. The detachment of the holding elements can either be done manually by means of a removal tool or be performed automatically via a robot. By this design, a simple solubility of the formwork element is given together with the holding element of the formwork support and there are no residues, such as hot melt on the formwork back.
Eine erfindungsgemäße Ausführungsform der hier vorliegenden Erfindung sieht vor, dass zwischen Halteelement und Schalungselement ein komprimierbarer Abstandhalter angeordnet ist. Weiters kann vorgesehen sein, dass der komprimierbare Abstandhalter das Halteelement in einem Abstand zur Schalungsauflage hält, wobei das in Abstand gehaltene Halteelement das Schalungselement noch nicht an der Schalungsauflage fixiert. Dadurch wird das Halteelement in einer, von der Schalungsauflage beabstandeten bzw. erhöhten, Position gehalten, in der der Magnet von der Schalungsauflage noch nicht angezogen wird bzw. noch nicht ausreichend angezogen wird um den Widerstand durch den komprimierbaren Abstandhalter zu überwinden. Dieser Abstand kann wenige Millimeter bis einige Zentimeter betragen, was jedoch stark von den verwendeten Magneten und von den Ausmaßen der zu fertigenden Fertigbauelemente und den dafür notwendigen Schalungselementen und Halteelementen abhängt. Da das Halteelement schon im Schalungselement angeordnet ist, aber aufgrund des Abstandhalters noch keine endgültige Fixierung an der Schalungsauflage möglich ist, kann beispielsweise händisch oder durch einen Schalungsroboter das Schalungselement auf der Schalungsauflage in die gewünschte Position verschoben werden. Nach Positionieren der Schalungselemente an den gewünschten Positionen kann vorgesehen sein, dass das in das Schalungselement eingesetzte Halteelement durch Bewegen des Halteelementes in Richtung der Schalungsauflage unter Komprimierung des Abstandhalters in eine Fixierposition zur Schalungsauflage gelangt und das Schalungselement magnetisch an der Schalungsauflage hält.An inventive embodiment of the present invention provides that between the holding element and formwork element, a compressible spacer is arranged. Furthermore, it can be provided that the compressible spacer holds the holding element at a distance from the formwork support, wherein the holding element at a distance not yet fixed the formwork element to the formwork support. As a result, the holding element is held in a position spaced from the formwork support or raised position, in which the magnet is not yet attracted to the formwork support or is not yet sufficiently attracted to overcome the resistance by the compressible spacer. This distance can be a few millimeters to a few centimeters, but this depends greatly on the magnets used and on the dimensions of the prefabricated components to be manufactured and the necessary formwork elements and retaining elements. Since the retaining element is already arranged in the formwork element, but due to the spacer still no final fixation on the formwork support is possible, for example, manually or by a shuttering robot, the formwork element can be moved to the formwork support in the desired position. After positioning the formwork elements to the desired positions can be provided that the holding element inserted into the formwork element passes by moving the holding element in the direction of the formwork support under compression of the spacer in a fixing position for formwork support and holds the formwork element magnetically on the formwork support.
Eine Ausführungsform sieht dabei vor, dass das Bewegen des Haltelements durch Drücken durch einen Schalungsroboter erfolgt.One embodiment provides that the movement of the holding element is carried out by pressing by a shuttering robot.
Ein mögliches Ausführungsbeispiel sieht dabei vor, dass der komprimierbare Abstandhalter als Feder ausgeführt ist, welche zwischen dem Kopfteil des Halteelementes und dem Schalungselement angeordnet ist. Diese Feder beabstandet das gesamte Halteelement derart von der Schalungsauflage, dass eine Position, in der noch keine ausreichende Magnetkraft vorliegt, zum Fixieren des Halteelementes gehalten wird.One possible embodiment provides that the compressible spacer is designed as a spring, which is arranged between the head part of the holding element and the formwork element. This spring distanced the entire holding element from the formwork support in such a way that a position in which sufficient magnetic force is not yet present is held for fixing the holding element.
Eine andere Ausführungsform dieses Abstandhalters sieht vor, dass der komprimierbare Abstandhalter durch einen zumindest teilweise komprimierbaren Bereich des Schalungselements selbst gebildet ist. Hierbei wird die Ausnehmung bzw. das Schalungselement derart zugeschnitten, dass das Halteelement beim Einbringen in das Schalungselement noch gar nicht in die Fixierposition mit einer darunter liegenden Schalungsauflage gelangen kann. Dabei kann vorgesehen sein, dass der komprimierbare Abstandhalter im Schalungselement durch einen vorzugsweise keilförmigen, in Richtung Schalungselement gerichteten Fortsatz am Kopfteil des Halteelementes komprimierbar ist. Im Besonderen kann dabei vorgesehen sein, dass der Fortsatz des Halteelementes in Fixierposition in das, aus vorzugsweise weichem Material bestehende Schalungselement eindringt bzw. dieses komprimiert. Das Material des Schalungselementes, beispielsweise Styropor oder Holz, soll dabei soweit eindrückbar sein, dass der vor dem Eindrücken des Halteelementes bestehende Abstand zwischen Unterseite des Halteelementes und Schalungsauflage im bzw. in das Schalungselement eindrückbar ist. Bei einer bevorzugten Ausführungsform beträgt dieser Abstand ca. 3 mm.Another embodiment of this spacer provides that the compressible spacer is formed by an at least partially compressible portion of the formwork element itself. In this case, the recess or the formwork element is cut in such a way that the holding element can not even reach the fixing position with an underlying formwork support when being introduced into the formwork element. It can be provided that the compressible spacer in the formwork element is compressible by a preferably wedge-shaped, directed towards formwork element projection on the head part of the holding element. In particular, it can be provided that the extension of the holding element in fixing position penetrates into the, preferably soft material existing formwork element or this compressed. The material of the formwork element, for example Styrofoam or wood, is intended to be depressible so far that the existing before the impressions of the holding element distance between the underside of the holding element and formwork support in or in the formwork element can be pressed. In a preferred embodiment, this distance is about 3 mm.
Je nach Ausführung des Halteelementes ist zumindest eine oder sind zumindest zwei Ausnehmungen vorgesehen. Wenn das Halteelement beispielsweise rotationssymmetrisch ausgeführt ist, könnte nur ein solches Halteelement keine drehfeste Fixierung des Schalungselementes bieten. Hierzu müssten dann zwei Halteelemente in zwei Ausnehmungen des Schalungselementes vorgesehen sein. Wenn das Halteelement nicht rotationssymmetrisch ausgeführt ist, ist eine Drehung des Schalungselementes um das Halteelement nicht möglich, wodurch eine Fixierung mit nur einem Halteelement ermöglicht wird.Depending on the design of the retaining element is at least one or at least two recesses are provided. If the holding element is designed, for example, rotationally symmetrical, only such a holding element could offer no rotationally fixed fixation of the formwork element. For this purpose, then two retaining elements would have to be provided in two recesses of the formwork element. If the holding element is not rotationally symmetrical, a rotation of the formwork element to the holding element is not possible, whereby a fixation with only one holding element is made possible.
Eine vorteilhafte Ausführungsform sieht dabei vor, dass die zumindest eine Ausnehmung als im Wesentlichen vertikale Durchgangsbohrung durch das Schalungselement ausgeführt ist. Weiters ist vorteilhaft vorgesehen, dass das Schalungselement aus Metall, beispielsweise Stahl, Polystyrol, Holz oder Ähnlichem besteht.An advantageous embodiment provides that the at least one recess is designed as a substantially vertical through hole through the formwork element. Furthermore, it is advantageously provided that the formwork element consists of metal, for example steel, polystyrene, wood or the like.
Schutz wird darüber hinaus auch begehrt für ein Verfahren zum Anbringen eines Schalungselementes durch zumindest ein Halteelement auf einer Schalungsauflage für Fertigbauelemente gemäß die Lehre des Anspruchs 13, wobei in einem ersten Schritt das Positionieren eines Schalungselementes mit mindestens einem in eine Ausnehmung des Schalungselementes eingebrachtem, einen Magneten aufweisenden Halteelement auf der Schalungsauflage, und in einem zweiten Schritt das Bewegen des Halteelementes in eine Fixierposition zur Schalungsauflage, in der das Halteelement samt Schalungselement magnetisch an der Schalungsauflage fixiert ist, vorgesehen ist.Protection is also desired for a method for attaching a formwork element by at least one holding element on a formwork support for prefabricated elements according to the teaching of claim 13, wherein in a first step, the positioning of a formwork element with at least one introduced into a recess of the formwork element, a magnet having holding member on the formwork support, and in a second step, the movement of the holding element in a fixing position for shuttering, in which the holding element together with shuttering element is magnetically fixed to the formwork support, is provided.
Eine besondere Ausführungsform sieht dabei vor, dass beim Bewegen des in ein Schalungselement eingesetzten Halteelementes in Richtung Schalungsauflage das Schalungselement unter Komprimierung eines Abstandhalters an der Schalungsauflage fixiert wird.A particular embodiment provides that when moving the retaining element used in a formwork element in the direction of formwork support the formwork element is fixed under compression of a spacer on the formwork support.
Eine weitere Ausführungsvariante sieht vor, dass das Anbringen des zumindest einen Schalungselementes durch zumindest ein Halteelement auf einer Schalungsauflage für Fertigbauelemente unter Verwendung eines Schalungsroboters erfolgt. Der Schalungsroboter führt dabei zumindest einen Schritt dieses Verfahrens durch, während andere Schritte auch händisch erfolgen können.A further embodiment provides that the attachment of the at least one formwork element by at least one holding element on a formwork support for prefabricated components using a shuttering robot takes place. The formwork robot performs at least one step of this process, while other steps can also be done manually.
Weiters wird Schutz begehrt für ein Verfahren zum Herstellen eines Fertigbauelementes auf einer Schalungsauflage, wobei in einem ersten Schritt das Positionieren eines Schalungselementes mit mindestens einem in eine Ausnehmung des Schalungselementes eingebrachtem, einen Magneten aufweisenden Halteelement auf der Schalungsauflage, in einem zweiten Schritt das Bewegen des Halteelementes in eine Fixierposition zur Schalungsauflage, in der das Halteelement samt Schalungselement magnetisch an der Schalungsauflage fixiert ist, in einem dritten Schritt das Herstellen eines Fertigbauelementes durch Eingießen eines aushärtbaren Materials, vorzugsweise Beton, in zumindest einen Raum zwischen Schalungselementen, und in einem vierten Schritt das Entfernen der Halteelemente von den Schalungselementen und Entfernen der Schalungselemente von der Schalungsauflage vorgesehen ist.Furthermore, protection is sought for a method for producing a prefabricated component on a formwork support, wherein in a first step, the positioning of a formwork element with at least one introduced into a recess of the formwork element, a magnet-containing holding element on the formwork support, in a second step, the movement of the holding element in a fixing position to the formwork support, in which the holding element together with the formwork element is magnetically fixed to the formwork support, in a third step, the manufacture of a finished component by pouring a curable material, preferably concrete, in at least one space between formwork elements, and in a fourth step, the removal the holding elements of the formwork elements and removing the formwork elements is provided by the formwork support.
Eine Ausführungsvariante sieht dabei vor, dass das Herstellen eines Fertigbauelementes auf einer Schalungsauflage unter Verwendung eines Schalungsroboters bzw. Entschalungsroboters erfolgt. Hierbei soll zumindest ein Verfahrensschritt durch den Schalungsroboter durchgeführt werden.One embodiment variant provides that the production of a finished component takes place on a formwork support using a formwork robot or demoulding robot. In this case, at least one method step should be performed by the shuttering robot.
Generell können diese Verfahrensschritte durch einen Schalungsroboter oder gänzlich händisch diese Schritte durchgeführt werden. Zusätzlich kann auch der Zuschnitt der einzelnen Schalungselemente automatisiert erfolgen. Diese Schnitte können dabei in 90° Winkeln, in Gehrung oder aber mit Rundungen oder sonstigen Formen ausgeführt sein. Auf der Schalungsauflage bzw. auf dem Schalungstisch können zuerst die allgemeinen Formen durch standardisierte Schalungselemente positioniert werden, um anschließend die zugeschnittenen Schalungselemente bzw. Sonderschalungselemente anzupassen. Diese so genannte Restschalung wird so präpariert, dass die Schalung beidseitig angießbar ist. Nach Einbringen der Halteelemente in die Ausnehmungen der Schalungselemente kann durch Drücken der Halteelemente in die aktivierte Position die Fixierung erfolgen. Nach dem Eingießen und Aushärten des Betons kann beispielsweise ein Entschalungsroboter zuerst die Magnete bzw. die Halteelemente entnehmen, wonach die Schalungselemente vom Fertigbauelement und von der Schalungsauflage getrennt werden. Die Reihenfolge dieser Vorgänge nach dem Aushärten des Betons ist beliebig.In general, these steps can be performed by a shuttering robot or entirely by hand these steps. In addition, the blank of the individual formwork elements can be automated. These cuts can be made in 90 ° angles, mitred or else with curves or other shapes. On the formwork support or on the formwork table, the general forms can first be positioned by means of standardized formwork elements in order subsequently to adapt the cut formwork elements or special formwork elements. This so-called residual formwork is prepared in such a way that the formwork can be cast on both sides. After introducing the retaining elements into the recesses of the formwork elements can be done by pressing the retaining elements in the activated position fixation. After pouring and curing the concrete, for example, a demoulding robot can first remove the magnets or the holding elements, after which the formwork elements are separated from the finished component and from the formwork support. The order of these operations after curing of the concrete is arbitrary.

Zusammenfassend sollen im Folgenden noch einmal einige Vorteile der hier vorliegenden Erfindung angeführt werden:In summary, some advantages of the present invention will be mentioned again below:
Durch diese Ausführung mit magnetischen Halteelementen bleiben vor allem die Stahlpalette bzw. die Schalungsauflage sauber. Die Haltekraft der Magnete kann variieren, wobei die Haltekraft beispielsweise vom Durchmesser des Magneten oder vom magnetischen Kraftfeld zwischen Schalungsauflage und Magnet abhängen kann. Die Federkraft der Abstandhalter kann variiert werden und an den jeweiligen Magneten angepasst werden.By this design with magnetic holding elements especially the steel pallet or the formwork support remain clean. The holding force of the magnets can vary, wherein the holding force can depend, for example, on the diameter of the magnet or on the magnetic force field between the formwork support and the magnet. The spring force of the spacers can be varied and adapted to the respective magnet.
Das Zuschneiden der Styroporpassstücke mit dreidimensionalem Schnitt kann vollständig - beispielsweise in Verbindung mit einem Schalungsroboter - automatisiert werden. Bei längeren Styroporpassstücken kann die Anzahl der Magnete beliebig festgelegt bzw. optimiert werden. Die Rundlöcher können hierbei im Schalungselement (Styropor) automatisch beim Längenzuschnitt eingearbeitet werden.The trimming of the styrofoam adapters with a three-dimensional cut can be completely automated, for example in conjunction with a shuttering robot. For longer Styroporpassstücken the number of magnets can be set or optimized arbitrarily. The round holes can be incorporated automatically in the formwork element (Styrofoam) during length cutting.
Generell läst sich ein solches System auch bei anderen Schalungen (wie beispielsweise Fensterzargen, sonstige Aussparungen aus Holz oder Standardteile aus Kunststoff) verwenden, mit dem Vorteil, dass die Halteelemente mit den Magneten die niederzuhaltende Schalung vertikal sowie horizontal formschlüssig mit dem Schalblech verbindet. Die Reinigung der Halteelemente mit deren Magnetköpfen ist relativ einfach, da der Magnet und der Fußteil bzw. Schaft vom Styropor bzw. vom Schalungselement während der Verarbeitung umhüllt wird. Lediglich der Kopfteil des Halteelementes muss demnach gereinigt werden.In general, such a system can also be used in other formwork (such as window frames, other recesses made of wood or standard plastic parts), with the advantage that the holding elements with the magnets, the formwork to be held down vertically and horizontally positively connected to the formwork panel. The cleaning of the holding elements with their magnetic heads is relatively simple, since the magnet and the foot part or shaft is enveloped by the polystyrene or the formwork element during processing. Only the head part of the holding element must therefore be cleaned.
Generell muss das Schalungselement bzw. das Halteelement nicht direkt auf einer metallischen Schalungsauflage aufliegen, sondern es kann auch eine dazwischen liegende, wie auch immer ausgestaltete, zusätzliche Auflage vorgesehen sein, durch welche hindurch die magnetische Anziehung wirkt.In general, the formwork element or the holding element does not have to rest directly on a metallic formwork support, but it can also be an intermediate, however designed, additional support be provided through which the magnetic attraction acts.
Generell kann das Halteelement zum Halten von standardisierten Schalungselementen, zugeschnittenen Schalungselementen oder Sonderschalungselementen dienen. Auch verschiedene Schalungshöhen können durch einfaches Austauschen bzw. zur Verfügung stellen von unterschiedlichen Halteelementen abgedeckt werden.In general, the holding element can be used to hold standardized formwork elements, cut formwork elements or special formwork elements. Even different formwork heights can be covered by simply replacing or making available of different support elements.
