Description

Schalungseinrichtung  formwork device
Die vorliegende Erfindung bezieht sich auf eine Schalungseinrichtung für eine Batterieschalung zum Herstellen von Bauelementen insbesondere Betonfertigteilen und auf eine Batterieschalung mit zumindest einer erfindungsgemäßen Schalungseinrichtung. The present invention relates to a formwork device for a battery formwork for the manufacture of components, in particular precast concrete elements, and to a battery mold with at least one formwork device according to the invention.
Bei der Serienfertigung von Betonfertigteilen kommen häufig Batterieschalungen zum Einsatz. Insbesondere bei der Herstellung von Gebäuden in Plattenbauweise werden häufig Betonfertigteile verwendet. Diese Betonfertigteile können schnell und günstig in Batterieschalungen hergestellt werden. Bei herkömmlichen Batterieschalungen werden als Schalungseinrichtungen sogenannte Schottwände verwendet, die nebeneinander angeordnet sind. Die Schottwände spannen jeweils vertikale Ebenen auf. Zwischen den Schottwänden sind Schalelemente zum Beispiel für Türen, Fenster und so weiter angebracht, die zusammen mit den beidseitig angeordneten Schottwänden jeweils mit Beton zu füllende Hohlräume begrenzen. Die Schottwände werden je nach Bedarf mit den entsprechenden Schalelementen bestückt. Dazu bringt ein Werker die Schalelemente zum Beispiel mit Magnethaltern an den aus Stahl bestehenden Schottwänden an. Während der Fertigung sind die Schottwände gegeneinander verspannt, um eine ausreichende Dichtheit der Hohlräume zu gewährleisten. Die Hohlräume sind nach oben hin offen und werden zum Herstellen der Betonfertigteile mit Beton gefüllt. Dabei werden die zwischen den Schottwänden angeordneten Hohlräume im Wesentlichen gleichzeitig mit Beton gefüllt. Nach dem Aushärten des Betons wird die Verspannung gelöst und die ausgehärteten Betonfertigteile können der Batterieschalung entnommen werden. Durch die gleichzeitige Fertigung mehrerer Betonfertigteile ist es mit der Batterieschalung möglich, Betonfertigteile schnell und kostengünstig zu produzieren. Andererseits ist die Handhabung der großen und vergleichsweise schweren Schottwände nicht ganz einfach. Auch ist das Bestücken der Schottwände mit Schalelementen recht mühsam. In the series production of precast concrete parts often battery molds are used. In particular, in the manufacture of prefabricated buildings are often precast concrete parts used. These precast concrete parts can be produced quickly and cheaply in battery molds. In conventional battery molds so-called shuttering walls are used as shuttering, which are arranged side by side. The bulkhead walls each span vertical planes. Between the bulkheads formwork elements are for example for doors, windows and so on attached, which limit together with the partition walls arranged on both sides with concrete to be filled cavities. The bulkheads are equipped as needed with the appropriate formwork elements. For this purpose, a worker attaches the formwork elements, for example with magnetic holders, to the steel bulkheads. During manufacture, the bulkheads are braced against each other to ensure sufficient tightness of the cavities. The cavities are open at the top and are filled with concrete for producing the precast concrete parts. The cavities arranged between the bulkheads are filled substantially simultaneously with concrete. After hardening of the concrete, the tension is released and the hardened precast concrete parts can be removed from the battery mold. By producing several precast concrete parts at the same time, battery molds make it possible to produce precast concrete parts quickly and inexpensively. On the other hand, the handling of the large and relatively heavy bulkheads is not easy. Also, the loading of the bulkhead walls with formwork elements is quite tedious.
Die DE 10 2015 209 157 beschreibt eine Schalungseinrichtung für eine Batterieschalung zum Herstellen von Bauelementen, die zwei Schalungsplatten aufweist. Eine solche Schalungseinrichtung wird auch als Schmetterlingsschalung bezeichnet. Diese Schalungseinrichtung ermöglicht bereits eine wesentliche Erleichterung bei der Produktion von Betonfertigteilen. DE 10 2015 209 157 describes a shuttering device for a battery mold for the manufacture of components which has two shuttering panels. Such a formwork device is also referred to as butterfly formwork. This formwork device already allows a substantial relief in the production of precast concrete parts.
Es ist jedoch wünschenswert und die Aufgabe der vorliegenden Erfindung den Fertigungspro- zess noch flexibler zu gestalten, um eine leichtere Bestückung der Schalungsplatten durch Personen oder Maschinen zu ermöglichen. Diese Aufgabe wird erfindungsgemäß gelöst durch eine Schalungseinrichtung für eine Batterieschalung zum Herstellen von Bauelementen, insbesondere Betonfertigteilen, die zumindest zwei Schottwände aufweist, und die Schalungseinrichtung zwei Schalungsplatten aufweist, die lösbar gelenkig miteinander verbindbar sind, um von einem aufgefalteten Zustand in einen gefalteten Zustand überführt zu werden, wobei jede Schalungsplatte eine Schalungsvorderseite zum Anbringen von Schalelementen und eine Schalungsrückseite aufweist, und die Schalungsrückseiten der beiden Schalungsplatten im gefalteten Zustand einander zugewandt sind, und die Schalungseinrichtung dafür vorgesehen ist, zwischen den Schottwänden positioniert zu werden. However, it is desirable and the object of the present invention to make the manufacturing process even more flexible, in order to facilitate easier assembly of the formwork panels by persons or machines. This object is achieved by a shuttering device for a battery mold for the manufacture of components, especially precast concrete parts, which has at least two bulkheads, and the formwork device has two formwork panels which are releasably articulated interconnected to transferred from a folded state to a folded state each formwork panel having a formwork front side for attaching formwork elements and a formwork back side, and the formwork backs of the two formwork panels in the folded state facing each other, and the formwork means is intended to be positioned between the bulkheads.
Diese Lösung hat den Vorteil, dass die Schalungsplatten im nicht verbundenen bzw. im getrennten Zustand unabhängig voneinander mit Schalelementen, zum Beispiel für Türen und Fenster für ein Betonfertigteil, von Personen oder Maschinen bestückt werden können. Auf diese Weise kommen Personen oder Maschinen leichter von allen Seiten an die Schalungsplatten heran. Auch kann durch die Bestückung im nicht verbundenen Zustand der Schalungsplatten der Platzbedarf zum Beispiel in Fertigungsstraßen gegenüber miteinander verbundenen Schalungsplatten wesentlich verringert werden. Durch die Möglichkeit einer Bestückung der Schalungsplatten mit Schalelementen in liegendem Zustand der Schalungsplatten wird die Automatisierung dieses Vorgangs erleichtert. Nach dem Bestücken können die Schalungsplatten wieder miteinander verbunden werden, und in einen gefalteten Zustand überführt werden. Danach kann die Schalungseinrichtung mit den beiden Schalungsplatten zwischen den Schottwänden positioniert werden. Auf diese Weise ist eine flexiblere und leichtere Handhabung der Schalungseinrichtung möglich. Gleichzeitig wird der Platzbedarf bei der Bestückung verringert. Somit können auch die Ausmaße einer Fertigungsstraße verringert werden. This solution has the advantage that the formwork panels in the unconnected or in the separated state independently of each other with scarf elements, for example, for doors and windows for a precast concrete part of people or machines can be fitted. In this way, persons or machines come easier from all sides of the formwork panels. Also can be significantly reduced by the assembly in the non-connected state of the formwork panels of space requirements, for example, in production lines opposite interconnected formwork panels. The possibility of equipping the shuttering panels with formwork elements in the lying state of the formwork panels, the automation of this process is facilitated. After loading, the formwork panels can be reconnected and transferred to a folded condition. Thereafter, the formwork device can be positioned with the two formwork panels between the bulkheads. In this way, a more flexible and easier handling of the formwork device is possible. At the same time, the space required for assembly is reduced. Thus, the dimensions of a production line can be reduced.
In einer vorteilhaften Weiterentwicklung der Erfindung können die Schalungsplatten im Wesentlichen rechteckig und vorzugsweise einseitig, bevorzugt an der längeren Längsseite, miteinander verbindbar sein. Die Form der Schalungsplatten entspricht dadurch im Wesentlichen der Form der Schottwände, so dass die Kompatibilität mit den Schottwänden gewährleistet ist. Insbesondere für eine mögliche Nachrüstung bestehender Batterieschalungen kann dieses vorteilhaft sein. Günstig kann es dabei sein, wenn die im Wesentlichen rechteckigen Schalungsplatten einseitig, vorzugsweise an der längeren Längsseite, miteinander verbindbar sind. Die Verbindung folgt dadurch einer während des Einsetzvorganges der gefalteten Schalungsplatten horizontal verlaufenden Linie. Die beiden Schalungsplatten erstrecken sich dadurch ausgehend von dieser Linie nach unten, hängen sozusagen von dieser Linie ausgehend nach unten. Auf diese Weise ist eine einfachere Handhabung der Schalungseinrichtung möglich. Es kann auch von Vorteil sein, wenn die Schalungsplatten über wenigstens ein Scharniergelenk miteinander verbindbar sind. Auf diese Weise kann das Überführen der Schalungsplatten vom aufgefalteten in den gefalteten Zustand und somit auch deren Handhabung weiter vereinfacht werden. In an advantageous further development of the invention, the formwork panels can be connected to one another in a substantially rectangular manner and preferably on one side, preferably on the longer longitudinal side. The shape of the formwork panels thereby corresponds substantially to the shape of the bulkheads, so that the compatibility with the bulkheads is guaranteed. This can be advantageous in particular for a possible retrofitting of existing battery molds. It may be favorable if the substantially rectangular shuttering panels can be connected to one another on one side, preferably on the longer longitudinal side. The connection thus follows a line running horizontally during the insertion process of the folded shuttering panels. As a result, the two formwork panels extend downwards from this line, hanging down from this line, so to speak. In this way, easier handling of the formwork device is possible. It can also be advantageous if the shuttering panels can be connected to one another via at least one hinge joint. In this way, the transfer of the shuttering panels from the folded in the folded state and thus also their handling can be further simplified.
Günstig kann es auch sein, wenn jede der Schalungsplatten zumindest eine Einhängerolle und/oder zumindest eine erste Stützrolle und/oder zumindest eine zweite Stützrolle aufweist. Durch die Einhängerolle können die Schalungsplatten in der Batterieschalung leichter verschoben werden. Während der Bestückung liegen die Schalungsplatten mit der ersten Stützrolle und/oder mit der zweiten Stützrolle auf einer Unterlage auf. Die Schalungsplatten können mit Hilfe der Stützrollen leichter auf der Unterlage bewegt werden. Weiterhin wird das Überführen der miteinander verbundenen Schalungsplatten von einem aufgefalteten Zustand in einen gefalteten Zustand beziehungsweise von einem gefalteten Zustand in einen aufgefalteten Zustand durch die erste Stützrolle unterstützt. Beim Überführen der verbundenen Schalungsplatten vom aufgefalteten in den gefalteten Zustand beziehungsweise von dem gefalteten in den aufgefalteten Zustand stützt sich die erste Stützrolle zumindest zeitweise an der Unterlage ab und rollt zumindest zeitweise an dieser entlang. Auf diese Weise kann die Handhabung der Schalungseinrichtung weiter vereinfacht werden. It may also be favorable if each of the shuttering panels has at least one suspension roller and / or at least one first support roller and / or at least one second support roller. The hanging roller makes it easier to move the shuttering panels in the battery mold. During assembly, the formwork panels with the first support roller and / or with the second support roller rest on a base. The shuttering panels can be moved more easily on the base with the help of the support rollers. Furthermore, the transfer of the interconnected formwork panels from a folded state to a folded state or from a folded state to a folded state is supported by the first support roller. When transferring the connected shuttering panels from the folded to the folded state or from the folded to the unfolded state, the first support roller is supported at least temporarily on the base and rolls at least temporarily along this. In this way, the handling of the formwork device can be further simplified.
Weiterhin kann es sich als vorteilhaft erweisen, wenn die Einhängerolle an einer Schmalseite der Schalungsplatte und vorzugsweise in dem Bereich, an dem die beiden Schalungsplatten aneinandergrenzen, vorgesehen ist. Mit einer derartigen Konstruktion kann das Einhängen der Schalungsplatte in die Batterieschalung weiter vereinfacht werden. Furthermore, it may prove to be advantageous if the Einhängerolle on a narrow side of the formwork panel and preferably in the region where the two formwork panels adjoin is provided. With such a construction, the hooking of the formwork panel in the battery mold can be further simplified.
Zudem kann es vorteilhaft sein, wenn die erste Stützrolle an der dem Scharniergelenk gegenüberliegenden Längsseite der Schalungsplatte angeordnet ist. Auf diese Weise kann das Überführen der Schalungsplatten von einem aufgefalteten Zustand in einen gefalteten Zustand beziehungsweise von einem gefalteten Zustand in einen aufgefalteten Zustand noch besser unterstützt und somit vereinfacht werden. In addition, it may be advantageous if the first support roller is arranged on the longitudinal side of the shuttering panel opposite the hinge joint. In this way, the transfer of the shuttering panels from a folded state to a folded state or from a folded state to a deployed state can be better supported and thus simplified.
In einer vorteilhaften Weiterbildung der Erfindung kann die zweite Stützrolle auf der Schalungsrückseite der Schalungsplatte angeordnet sein. Dadurch kann die Schalungsplatte noch leichter auf einer Unterlage bewegt werden, wodurch die Handhabung noch weiter erleichtert werden kann. In an advantageous embodiment of the invention, the second support roller may be arranged on the formwork back of the formwork panel. As a result, the shuttering panel can be moved even more easily on a base, whereby the handling can be further facilitated.
Günstig kann es auch sein, wenn die ersten Stützrollen und/oder die zweiten Stützrollen von den Schalungsplatten der Schalungseinrichtung entlang der Schwenkachse versetzt zueinander an- geordnet sind. Im gefalteten Zustand sind die Schalungsrückseiten der Schalungsplatten, an denen die zweiten Stützrollen angebracht sind, einander zugewandt. Durch die versetzte Anordnung der Stützrollen kann der Abstand der beiden Schalungsplatten im gefalteten Zustand verringert werden. Auch die versetzte Anordnung der ersten Stützrollen ermöglicht einen geringeren Abstand der beiden Schalungsplatten im gefalteten Zustand. It may also be favorable if the first support rollers and / or the second support rollers are offset from one another by the formwork panels of the formwork device along the pivot axis. are ordered. In the folded state, the formwork backs of the formwork panels, on which the second support rollers are mounted, facing each other. Due to the staggered arrangement of the support rollers, the distance of the two shuttering panels in the folded state can be reduced. The staggered arrangement of the first support rollers allows a smaller distance of the two formwork panels in the folded state.
Außerdem kann es günstig sein, wenn die erste Stützrolle und/oder die zweite Stützrolle schwenkbar ist. Auf diese Weise kann die Schalungsplatte noch leichter auf der Unterlage bewegt werden. In addition, it may be favorable if the first support roller and / or the second support roller is pivotable. In this way, the formwork panel can be moved even easier on the pad.
Auch kann es sich als vorteilhaft erweisen, wenn die Einhängerolle zumindest abschnittsweise aus Stahl besteht und/oder die erste Stützrolle und/oder die zweite Stützrolle zumindest abschnittsweise aus Kunststoff besteht. Somit können die Schalungsplatten leichter bewegt werden bei gleichzeitiger hoher Stabilität der Einhängerolle beziehungsweise der Stützrollen. It may also prove advantageous if the suspension roller is at least partially made of steel and / or the first support roller and / or the second support roller is at least partially made of plastic. Thus, the formwork panels can be easily moved while high stability of the suspension role or the support rollers.
In einer vorteilhaften Weiterentwicklung der Erfindung kann die Schalungseinrichtung über die ersten Stützrollen zumindest zeitweilig während des Auffaltens und/oder Entfaltens und/oder Abheben von und/oder Ablegen auf einer Unterlage vorzugsweise beweglich abstützbar sein. Durch das Abstützen der Schalungseinrichtung kann die Handhabung der Schalungseinrichtung während des Auffaltens und/oder Entfaltens und/oder Abheben von und/oder Ablegen auf einer Unterlage weiter vereinfacht werden. In an advantageous further development of the invention, the formwork device can be supported, preferably at least temporarily, during the unfolding and / or unfolding and / or lifting off and / or depositing on a base via the first support rollers. By supporting the formwork device, the handling of the formwork device during the unfolding and / or unfolding and / or lifting off and / or depositing on a base can be further simplified.
Zudem wird die obige Aufgabe gelöst durch eine Batterieschalung mit zumindest einer erfindungsgemäßen Schalungseinrichtung, bei der die Schalungsplatten im verbundenen oder un- verbundenen Zustand in die Batterieschalung eingesetzt werden können. In addition, the above object is achieved by a battery mold with at least one formwork device according to the invention, in which the formwork panels can be used in the connected or unconnected state in the battery mold.
Diese Lösung hat den Vorteil, dass der Fertigungsprozess noch flexibler gestaltet werden kann. Insbesondere können die Schalungsplatten im unverbundenen Zustand bestückt werden, und auch in diesem Zustand in die Batterieschalung eingesetzt werden. Die Ausmaße von unverbundenen Schalungsplatten sind wesentlich geringer als von verbundenen Schalungsplatten. Da auch unverbundene Schalungsplatten in die Batterieschalung eingesetzt werden können, ist eine Verbindung der Schalungsplatten vor dem Einsetzen in die Batterieschalung nicht mehr nötig. Somit kann die Handhabung weiter vereinfacht und der Platzbedarf weiter verringert werden. Vorteilhaft kann es sein, wenn die im unverbundenen Zustand eingesetzten Schalungsplatten miteinander verbindbar sind. Auf diese Weise kann die Handhabung der Schalungsplatten in der Batterieschalung weiter vereinfacht werden. This solution has the advantage that the manufacturing process can be made even more flexible. In particular, the formwork panels can be fitted in the unconnected state, and be used in this condition in the battery mold. The dimensions of unconnected shuttering panels are much lower than of connected shuttering panels. Since unconnected shuttering panels can be used in the battery mold, a connection of the shuttering panels before insertion into the battery mold is no longer necessary. Thus, the handling can be further simplified and the space required can be further reduced. It may be advantageous if the formwork panels used in the unconnected state are connectable to each other. In this way, the handling of the shuttering panels in the battery mold can be further simplified.
Weiter hin kann es vorteilhaft sein, wenn die Schalungsplatten hängend in der Batterieschalung angeordnet sind, da dadurch der Platzbedarf weiter verringert werden kann. Farther, it may be advantageous if the formwork panels are arranged hanging in the battery mold, as this space requirements can be further reduced.
Auch kann es sich als günstig erweisen, wenn die Batterieschalung zumindest eine Trageinrichtung, vorzugsweise eine Schiene, zur Aufnahme der Einhängerolle der Schalungsplatte aufweist. Auf diese Weise kann die Handhabung noch weiter vereinfacht werden. It may also prove to be advantageous if the battery mold has at least one support device, preferably a rail, for receiving the engagement roller of the shuttering panel. In this way, the handling can be further simplified.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles und zugehöriger Zeichnungen näher erläutert. The invention will be explained in more detail below with reference to an embodiment and associated drawings.

Figur 1 zeigt eine schematische Darstellung einer Batterieschalung 1 mit Schalungseinrichtungen 5', wie sie aus der DE 10 2015 209 157 bekannt ist. Die Batterieschalung 1 wird zum Herstellen von nicht gezeigten Bauelementen und insbesondere von Betonfertigteilen für Gebäude verwendet. Die Batterieschalung 1 weist ein Tragegestell 2 auf mit voneinander beabstandeten Auflageabschnitten 3. Die Anzahl der Auflageabschnitte 3 in der Figur 1 ist nur als beispielhaft anzusehen, und kann den Gegebenheiten angepasst werden. Weiterhin umfasst die Batterieschalung 1 zwei Trageinrichtungen 4, in der die Schottwände 6 und die Schalungseinrichtungen 5' hängend und beweglich, d. h. in der vorliegenden Ausführungsform verschiebbar, aufgenommen sind. Die Schalungseinrichtungen 5' befinden sich dabei zwischen den Schottwänden 6. Zwischen zumindest einer Schottwand 6 und einer Schalungseinrichtung 5' wird ein mit Beton zu befüllender Hohlraum ausgebildet, wobei bevorzugt die Schalungseinrichtung 5' nicht gezeigte Schalelemente trägt, welche die Kontur des Betonfertigteils bestimmen. Die Schalelemente können zum Beispiel Türen- oder Fensterausschnitte begrenzen und dichten zudem während des Betonierens den mit Beton gefüllten Hohlraum ab. Die Schalelemente können zum Beispiel mit Magnethaltern an der Schalungseinrichtung 5' befestigt sein. Ergänzend können zudem eine nicht gezeigte Heizeinrichtung und/oder ein nicht gezeigter Rüttler an der Schalungseinrichtung 5 montiert sein. Die in der Figur 1 dargestellte Schalungseinrichtung 5' ist plattenförmig ausgebildet. Die Schalungseinrichtung 5' kann einseitig oder beidseitig mit entsprechenden Schalelementen versehen sein. Wenn die Schalungseinrichtung 5' beidseitig mit Schalelementen versehen ist, kann sie dazu dienen, auf jeder Seite unterschiedliche Betonfertigteile herzustellen. Die beidseitig mit Schalelementen bestückte Schalungseinrichtung 5' wie auch die einseitig mit Schalungseinrichtung 5' wird zwischen zwei Schottwänden 6 eingesetzt und während des Betonierens mit diesen verspannt. FIG. 1 shows a schematic representation of a battery mold 1 with formwork devices 5 ', as is known from DE 10 2015 209 157. The battery mold 1 is used for the manufacture of components, not shown, and in particular of precast concrete parts for buildings. The battery mold 1 has a support frame 2 with spaced-apart support sections 3. The number of support sections 3 in the figure 1 is only as an example and can be adapted to the circumstances. Furthermore, the battery mold 1 comprises two support devices 4, in which the bulkheads 6 and the formwork devices 5 'are suspended and movable, ie slidably received in the present embodiment. The shuttering devices 5 'are located between the bulkheads 6. Between at least one bulkhead 6 and a formwork 5' is formed a cavity to be filled with concrete, preferably the shuttering 5 'wearing shells not shown, which determine the contour of the precast concrete part. The formwork elements can, for example, limit door or window cutouts and also seal off the concrete-filled cavity during concreting. The formwork elements can be fastened to the formwork device 5 'with magnetic holders, for example. In addition, a heater, not shown, and / or a vibrator, not shown, may also be mounted on the formwork device 5. The formwork device 5 'shown in FIG. 1 is plate-shaped. The formwork device 5 'can be provided on one side or on both sides with corresponding formwork elements. If the formwork device 5 'is provided on both sides with formwork elements, it can serve to produce different precast concrete elements on each side. The bilateral shuttering elements equipped with shuttering device 5 'as well as the one-sided shuttering device 5' is inserted between two bulkheads 6 and braced during concreting with these.
Die Anzahl der Trageinrichtungen 4 der Schottwände 6 und der Schalungseinrichtungen 5' ist als nur beispielhaft anzusehen und kann je nach den Gegebenheiten variiert werden. So können zum Beispiel Schalungseinrichtungen 5' für die Außenwände, Innenwände, den Boden sowie für das Dach eines Hauses vorgesehen sein, so dass mit der Batterieschalung 1 gleichzeitig die Bauelemente für ein ganzes Gebäude produziert werden können. Die Schottwände 6 und die Schalungseinrichtungen 5' sind zwischen zwei Abstützeinrichtungen 7 eingespannt. Die Anzahl der Abstützeinrichtungen 7 ist ebenfalls als nur beispielhaft anzusehen, und kann den Erfordernissen entsprechend variiert werden. Zumindest eine Abstützeinrichtung 7 ist beweglich, d. h. in der vorliegenden Ausführungsform verschieblich, in den Trageinrichtungen 4 aufgenommen. Zur Stabilisierung können die Schalungseinrichtungen 5' und die Abstützeinrichtungen 7 in der Betonierstellung durch eine oder mehrere stangenförmige Verbindungseinrichtungen 9 miteinander verbunden und verspannt werden. Die Anzahl der Verbindungseinrichtungen 9 kann den Verhältnissen angepasst werden. Anstelle von stangenförmigen Verbindungseinrichtungen 9 sind auch hydraulische Verbindungseinrichtungen möglich. Die stangenförmigen Verbindungseinrichtungen 9 sind jedoch besonders robust und einfach zu handhaben. Weiterhin weist die Batterieschalung 1 eine Hebeeinrichtung 8 auf, mit der zumindest eine der Schalungseinrichtungen 5' von der abgesenkten Betonierstellung in eine angehobene Transportstellung überführbar ist, in welcher die Schalungseinrichtung 5' über eine in der Betonierstellung befindliche Schalungseinrichtung 5' in einer Richtung im Wesentlichen senkrecht zur Anheberichtung X förderbar ist. Bei der Batterieschalung 1 werden die Schalungseinrichtungen 5' von oben in die Trageinrichtungen 4 eingehängt, so dass sie im eingehängten Zustand in Betonierstellung zwischen den Auflageabschnitten 3 vom Boden beabstandet sind. Die Gestaltung der Hebeeinrichtung 8 kann den Erfordernissen angepasst werden. Falls nötig, können auch mehrere Hebeeinrichtungen 8 verwendet werden. The number of support devices 4 of the bulkheads 6 and the formwork devices 5 'is to be regarded as only an example and can be varied depending on the circumstances. For example, shuttering means 5 'may be provided for the outer walls, inner walls, the floor and for the roof of a house so that the components for an entire building can be produced simultaneously with the battery mold 1. The bulkhead walls 6 and the formwork devices 5 'are clamped between two support devices 7. The number of support means 7 is also to be considered as exemplary only, and may be varied according to requirements. At least one support device 7 is movable, ie displaceable in the present embodiment, received in the support means 4. For stabilization, the formwork devices 5 'and the support means 7 in the concreting position can be interconnected and braced by one or more rod-shaped connecting devices 9. The number of connecting devices 9 can be adapted to the circumstances. Instead of rod-shaped connecting means 9 and hydraulic connection means are possible. However, the rod-shaped connecting devices 9 are particularly robust and easy to handle. Furthermore, the battery mold 1 has a lifting device 8 with which at least one of the formwork devices 5 'can be transferred from the lowered concreting position into a raised transport position, in which the formwork device 5' is essentially vertical in one direction via a formwork device 5 'located in the concreting position for lifting direction X is conveyed. In the case of the battery mold 1, the formwork devices 5 'are hooked from above into the support devices 4, so that they are spaced from the ground in the suspended state in concreting position between the support sections 3. The design of the lifting device 8 can be adapted to the requirements. If necessary, several lifting devices 8 can be used.
Die Hebeeinrichtung 8 ist auf zwei voneinander beabstandeten Führungseinrichtungen 25, die hier als Laufschienen 25 ausgebildet sind, in einer Spannrichtung der Schalungseinrichtungen 5 bewegbar. Weiterhin sind die Führungseinrichtungen 25 über den Trageinrichtungen 4 und parallel dazu angeordnet. Um die Batterieschalungen 1 kompakter zu gestalten, sind die Schalungseinrichtungen 5 an ihrem oberen Ende an den Trageinrichtungen 4 befestigt. The lifting device 8 is movable in a clamping direction of the formwork devices 5 on two guide devices 25 which are spaced apart from one another and which are designed here as running rails 25. Furthermore, the guide means 25 are arranged above the support means 4 and parallel thereto. In order to make the battery molds 1 more compact, the formwork devices 5 are attached at their upper end to the support means 4.
Die Batterieschalung 1 kann zumindest eine nicht dargestellte Beschwereinrichtung mit einem Hohlraum aufweisen, der vorzugsweise mit Sand, Wasser und/oder Beton befüllbar ist. Weiterhin kann die Beschwereinrichtung entleerbar und/oder entfernbar sein. Dadurch kann die Standfestigkeit und Stabilität der Batterieschalung erhöht werden. The battery mold 1 can have at least one summation device, not shown, with a cavity, which can preferably be filled with sand, water and / or concrete. Furthermore, the Beschwereinrichtung be emptied and / or removable. As a result, the stability and stability of the battery mold can be increased.
Die Figur 2 zeigt eine schematische Darstellung einer erfindungsgemäßen Schalungseinrichtung 5 in einer Draufsicht, die zum Beispiel in der in Figur 1 gezeigten Batterieschalung 1 anstatt der Schalungseinrichtung 5' verwendet werden kann. Die Schalungseinrichtung 5 weist zwei Schalungsplatten 10 auf, die lösbar gelenkig miteinander verbindbar sind, um von einem aufgefalteten Zustand in einen gefalteten Zustand überführt zu werden. In der Figur 2 sind die Schalungsplatten 10 miteinander verbunden und in einem aufgefalteten Zustand. In der Draufsicht auf die Figur 2 ist die Schalungsvorderseite 1 1 zum Anbringen von nicht dargestellten Schalelementen gezeigt. Weiterhin weist die Schalungsplatte 10 eine Schalungsrückseite 12 auf, die gegenüber der Schalungsvorderseite 1 1 angeordnet ist. Im gefalteten Zustand, der in der Figur 6 dargestellt ist, sind die Schalungsrückseiten 12 der beiden Schalungsplatten 10 einander zugewandt. Die Schalungseinrichtung 5 ist dafür vorgesehen, zwischen den Schottwänden 6 positioniert zu werden. Die Schalungseinrichtung 5 bzw. die Schalungsplatte 10 kann liegend bestückt werden. Weiterhin kann die Schalungseinrichtung 5 bzw. die Schalungsplatte 10 in sogenannten Umlaufanlagen mit Fördereinrichtungen transportiert werden. In den Umlaufanlagen können sich verschiedene Bearbeitungsstationen befinden. Nach dem Entformen kann die Schalungseinrich- tung 5 bzw. die Schalungsplatte 10 zum Beispiel an einer Arbeitsstation gereinigt und an einer anderen Arbeitsstation neu bestückt werden, bevor sie erneut in die Batterieschalung 1 eingehängt wird. 2 shows a schematic representation of a formwork device 5 according to the invention in a plan view, which can be used, for example, in the battery mold 1 shown in FIG. 1 instead of the formwork device 5 '. The formwork device 5 has two formwork panels 10 which are detachably hinged together to be transferred from a folded state to a folded state. In the figure 2, the shuttering panels 10 are interconnected and in a deployed state. In the plan view of Figure 2, the formwork front side 1 1 is shown for attaching formwork elements, not shown. Furthermore, the formwork panel 10 has a formwork rear side 12, which is arranged opposite the formwork front side 1 1. In the folded state, which is shown in the figure 6, the shuttering sides 12 of the two formwork panels 10 facing each other. The formwork device 5 is intended to be positioned between the bulkheads 6. The shuttering device 5 or the shuttering panel 10 can be fitted horizontally. Furthermore, the formwork device 5 or the formwork panel 10 can be transported in so-called circulation systems with conveyors. There may be various processing stations in the circulation systems. After removal from the mold, the formwork tion 5 or the formwork panel 10, for example, cleaned at a workstation and re-stocked at another workstation before being hooked into the battery mold 1 again.
Die Schalungsplatten 10 sind im Wesentlichen rechteckig und an der längeren Längsseite 13 über zwei Scharniergelenke 15 miteinander verbunden. Die Anordnung und Anzahl der Scharniergelenke 15 ist als nur beispielhaft anzusehen, und kann den Gegebenheiten angepasst werden. In der Figur 3 ist ein Scharniergelenk 15 aus der Figur 2 vergrößert dargestellt. Darauf wird später noch genauer eingegangen. The shuttering panels 10 are substantially rectangular and connected to each other at the longer longitudinal side 13 via two hinge joints 15. The arrangement and number of hinge joints 15 is to be regarded as exemplary only, and can be adapted to the circumstances. FIG. 3 shows a hinge joint 15 from FIG. 2 enlarged. This will be discussed in more detail later.
Jede der Schalungsplatten 10 weist zwei Einhängerollen 18, zwei erste Stützrollen 19 und zwei zweite Stützrollen 20 auf. Die Einhängerollen 18 sind jeweils an einer Schmalseite 14 der Schalungsplatten 10 und in dem Bereich, an dem die beiden Schalungsplatten 10 aneinander grenzen, angeordnet. Jede Schalungsplatte 10 weist zwei erste Stützrollen 19 an der den Scharniergelenken 15 gegenüberliegenden Längsseite 13 der Schalungsplatte 10 auf. Zwei zweite Stützrollen 20 sind jeweils auf der Schalungsrückseite 12 der Schalungsplatten 10 angeordnet. Die ersten Stützrollen 19 und die zweiten Stützrollen 20 von den Schalungsplatten 10 der Schalungseinrichtung 5 sind entlang der Schwenkachse 22 versetzt zueinander angeordnet. Durch diese Anordnung kann der Abstand der beiden Schalungsplatten 10 im gefalteten Zustand verringert werden. Each of the formwork panels 10 has two suspension rollers 18, two first support rollers 19 and two second support rollers 20. The suspension rollers 18 are each arranged on a narrow side 14 of the formwork panels 10 and in the region in which the two formwork panels 10 adjoin one another. Each formwork panel 10 has two first support rollers 19 on the hinge side 15 opposite longitudinal side 13 of the formwork panel 10. Two second support rollers 20 are each arranged on the formwork rear side 12 of the formwork panels 10. The first support rollers 19 and the second support rollers 20 of the formwork panels 10 of the formwork device 5 are offset along the pivot axis 22 to each other. By this arrangement, the distance between the two formwork panels 10 can be reduced in the folded state.
In der Figur 2 sind bei der oberen Schalungsplatte 10 die beiden ersten Stützrollen 19 jeweils am Rand der Schalungsplatte 10 angeordnet. Das ermöglicht eine leichte Handhabung der Schalungsplatte 10 beziehungsweise der Schalungseinrichtung 5. Jedoch sind die Anzahl und die Anordnung der Einhängerollen 18, der ersten Stützrollen 19 und der zweiten Stützrollen 20 als nur beispielhaft anzusehen und an die jeweiligen Erfordernisse anpassbar. In the figure 2, the two first support rollers 19 are each arranged at the edge of the formwork panel 10 in the upper formwork panel 10. This allows easy handling of the form panel 10 and the formwork device 5. However, the number and arrangement of the suspension rollers 18, the first support rollers 19 and the second support rollers 20 are to be considered as exemplary only and adaptable to the respective requirements.
Die Einhängerollen 18 sind über Halter 21 b an den Schmalseiten 14 der Schalungsplatten 10 derart befestigt, dass sie von den Schalungsplatten 10 hervorstehen. The suspension rollers 18 are mounted on holders 21 b on the narrow sides 14 of the formwork panels 10 such that they protrude from the formwork panels 10.
Weiterhin sind die ersten Stützrollen 19 über Halter 21 a derart an den Längsseiten 13 der Schalungsplatten 10 befestigt, dass sie davon hervorstehen. Furthermore, the first support rollers 19 are attached via holders 21 a on the longitudinal sides 13 of the formwork panels 10 that they protrude therefrom.
Es ist auch denkbar, dass die ersten Stützrollen 19 und/oder die zweiten Stützrollen 20 schwenkbar sind, wodurch die Bewegung der Schalungsplatten 10 auf einer Unterlage 23, wie sie in der Figur 5 gezeigt ist, noch leichter ist. Als besonders günstig hat es sich erwiesen, wenn die Einhängerolle 18 zumindest abschnittsweise aus Stahl und die ersten Stützrollen 19 und die zweite Stützrolle 20 zumindest abschnittsweise aus Kunststoff besteht. Jedoch kann auch jedes andere geeignete Material verwendet werden. It is also conceivable that the first support rollers 19 and / or the second support rollers 20 are pivotable, whereby the movement of the shuttering plates 10 on a base 23, as shown in Figure 5, is even easier. It has proven to be particularly favorable when the suspension roller 18 at least partially made of steel and the first support rollers 19 and the second support roller 20 at least partially made of plastic. However, any other suitable material may be used.
In der Figur 2 sind weiterhin die Rollenachsen 24a für die ersten Stützrollen und 24b für die Einhängerollen 18 eingezeichnet. FIG. 2 also shows the roller axles 24a for the first support rollers and 24b for the suspension rollers 18.
Die Figur 3 zeigt eine Vergrößerung eines Scharniergelenks 15, wie es in der Figur 2 dargestellt ist. An den Schalungsplatten 10 sind jeweils Scharniergelenkteile 16 angeordnet, die durch einen Bolzen 17 miteinander verbunden werden. Im verbundenen Zustand liegt jeweils ein Scharnierteil 16 eines Schalungselements 10 einem Scharnierteil 16 eines anderen Schalungselements 10 gegenüber. Der Bolzen 17 wird auf geeignete Weise vor dem Herausfallen gesichert. Nach Entfernen der nicht gezeigten Sicherung kann der Bolzen 17 aus den Scharniergelenkteilen 16 entfernt werden, so dass die Schalungsplatten 10 voneinander getrennt werden können und getrennt voneinander bestückt werden können. Das Scharniergelenk 15 ist nur als beispielhaft anzusehen. Es können auch andere geeignete Scharniergelenke verwendet werden. Anstatt von Scharniergelenken sind auch andere geeignete gelenkige Verbindungsarten oder eine Mischung von verschiedenen gelenkigen Verbindungsarten denkbar. FIG. 3 shows an enlargement of a hinge joint 15, as shown in FIG. On the formwork panels 10 each hinge joint parts 16 are arranged, which are connected by a bolt 17 with each other. In the connected state, a respective hinge part 16 of a formwork element 10 faces a hinge part 16 of another formwork element 10. The bolt 17 is suitably secured against falling out. After removal of the fuse, not shown, the bolt 17 can be removed from the hinge joint parts 16, so that the formwork panels 10 can be separated from each other and can be equipped separately. The hinge joint 15 is to be regarded as exemplary only. Other suitable hinges may be used. Instead of hinged joints, other suitable articulated types of connection or a mixture of different articulated types of connection are conceivable.
Die Figur 4 zeigt eine erfindungsgemäße Schalungseinrichtung 5 im verbundenen und aufgefalteten Zustand in einer Seitenansicht. Die ersten Stützrollen 19 sowie die zweiten Stützrollen 20 sind auf der Unterlage 23 beweglich abgestützt. Auf der Schalungsvorderseite 1 1 der Schalungsplatte 10 können nicht dargestellte Schalelemente, die die Kontur des Betonfertigteils bestimmen, aufgebracht werden. Die Schalelemente können zum Beispiel Türen- oder Fensterausschnitte begrenzen und dichten zudem während des Betonierens den mit Beton gefüllten Hohlraum ab. Die Schalelemente können zum Beispiel mit Magnethaltern an den Schalungsplatten 10 befestigt werden. Es sind auch andere Befestigungsmethoden möglich. Die Schalungsplatten können gemäß der gewünschten Befestigungsmethode gestaltet werden. 4 shows a formwork device 5 according to the invention in the connected and unfolded state in a side view.

The suspension rollers 18 are arranged in the carrying device 4. The formwork backs 12 of the formwork panels 10 are arranged adjacent to each other.
Gemäß der vorliegenden Erfindung können jedoch die Schalungsplatten 10 nicht nur im verbundenen Zustand, sondern auch im unverbundenen Zustand in die Batterieschalung 1 eingehängt werden. Ein Einhängen mit Hilfe der Einhängerollen 18 ist nicht unbedingt erforderlich. Die Schalungsplatten 10 können beziehungsweise die Schalungseinrichtung 10 kann auch mit anderen geeigneten Methoden in die Batterieschalung 1 eingesetzt werden. Weiterhin sind die im unverbundenen Zustand eingesetzten Schalungsplatten 10 auch in der Batterieschalung 1 miteinander verbindbar. Auf diese Weise kann der Fertigungsprozess sehr flexibel gestaltet werden, und die Handhabung wird vereinfacht. According to the present invention, however, the formwork panels 10 can be hung not only in the connected state, but also in the unconnected state in the battery mold 1. An attachment by means of the suspension rollers 18 is not absolutely necessary. The formwork panels 10 and the formwork apparatus 10 can also be used with other suitable methods in the battery mold 1. Furthermore, the formwork panels 10 used in the unconnected state can also be connected to one another in the battery mold 1. In this way, the manufacturing process can be made very flexible, and handling is simplified.
Durch die hängende Anordnung der Schalungsplatten 10 in der Batterieschalung 1 kann die Batterieschalung 1 kompakter gestaltet werden. Due to the suspended arrangement of the shuttering panels 10 in the battery mold 1, the battery mold 1 can be made more compact.
Mit Hilfe der erfindungsgemäßen Schalungseinrichtung 5 für eine Batterieschalung 1 beziehungsweise der Batterieschalung 1 mit einer erfindungsgemäßen Schalungseinrichtung 5 ist eine leichtere Bestückung der Schalungsplatten 10 durch Personen oder Maschinen möglich. Somit kann der Fertigungsprozess noch flexibler gestaltet werden. Insbesondere ist bei einer getrennten Bestückung der Schalungsplatten 10 eine leichtere Handhabung derselben möglich. Eine Person oder eine Maschine kommt leichter von allen Seiten an die Schalungsplatte 10 zum Bestücken heran. Zudem wird in Fertigungsstraßen weniger Platz benötigt. With the aid of the formwork device 5 according to the invention for a battery mold 1 or the battery mold 1 with a formwork device 5 according to the invention, easier assembly of the formwork panels 10 by persons or machines is possible. Thus, the manufacturing process can be made even more flexible. In particular, with a separate assembly of the shuttering panels 10, easier handling thereof is possible. A person or a machine is easier from all sides of the formwork panel 10 for loading approach. In addition, less space is needed in production lines.
