Description

WO 2014/174432 A1 FORMWORK DEVICE The present invention relates to a formwork device for a battery formwork for producing components, in particular precast concrete parts and to a battery formwork having at least one formwork device according to the invention.

Battery formworks are frequently used in the series production of precast concrete parts. In particular, precast concrete parts are frequently used in the manufacture of buildings in panel design. These precast concrete parts can be rapidly and favourably produced in battery formworks. In conventional battery formworks, so-called bulkheads which are arranged adjacent to one another are used as formwork devices. The bulkheads each span vertical planes. Formwork elements for example for doors, windows and so forth are attached between the bulkheads, which together with the bulkheads arranged on both sides each delimit cavities to be filled with concrete. The bulkheads are fitted with corresponding formwork elements as required. To this end, a worker attaches the formwork elements for example with magnetic holders to the bulkheads consisting of steel. During fabrication the bulkheads are braced towards one another to ensure a sufficient tightness of the cavities. The cavities are open towards the top and are filled with concrete to produce the precast concrete parts. In so doing, the cavities between the bulkheads are substantially simultaneously filled with concrete. After the concrete has set, the bracing is released and the set precast concrete parts can be removed from the battery formwork. As a result of the simultaneous fabrication of several precast concrete parts, it is possible to produce precast concrete parts rapidly and cost-effectively with the battery formwork. On the other hand, the handling of large and comparatively heavy bulkheads is not very easy. The fitting of the bulkheads with formwork elements is also very tedious.

DE 10 2015 209 157 describes a formwork device for a battery formwork for producing components having two formwork panels. Such a formwork device is also designated as butterfly formwork. This formwork device already makes it substantially easier to produce precast concrete parts.

However, it is desirable and the object of the present invention to make the production process even more flexible in order to make it easier for persons or machines to fit the formwork panels.

This object is solved according to the invention by a formwork 40 device for a battery formwork for producing components, in particular 1 WO 2014/174432 A1 precast concrete parts, having at least two bulkheads, and the formwork device has two formwork panels which can be connected together in a releasably articulated manner in order to be converted from an unfolded state into a folded state, wherein each formwork panel has a formwork front face for attaching formwork elements and a formwork rear face, and the formwork rear faces of the two formwork panels face each other in the folded state and the formwork device is provided to be positioned between the bulkheads.

This solution has the advantage that the formwork panels can be fitted with formwork elements, for example, for doors and windows for a precast concrete part, by persons or machines in the disconnected or in the separated state independently of one another. In this way persons or machines can more easily approach the formwork panels from all sides.

Also as a result of the fitting in the disconnected state of the formwork panels, the space requirement for example in production lines can be reduced substantially compared with interconnected formwork panels.

Automation of this process is facilitated by the possibility of fitting the formwork panels with formwork elements in the horizontal state of the formwork panels. After fitting, the formwork panels can be re-connected to one another and transferred into a folded state. The formwork device with the two formwork panels can then be positioned between the bulkheads.

In this way, a more flexible and easier handling of the formwork device is possible. At the same time the space requirement during fitting is reduced. Thus, the dimensions of a production line can also be reduced.

In an advantageous further development of the invention, the formwork panels are substantially rectangular and preferably be connectable to one another on one side, preferably on the longer longitudinal side. The shape of the formwork panels thus substantially corresponds to the shape of the bulkheads so that compatibility with the bulkheads is ensured. In particular, this can be advantageous for a possible retrofitting of existing battery formworks. It can be favourable if the substantially rectangular formwork panels can be connected to one another on one side, preferably on the longer longitudinal side. The connection thereby follows a line running horizontally during the insertion process of the folded formwork panels. The two formwork panels thereby extend downwards starting from this line, so to speak hang downwards starting from this line. In this way, an easier handling of the formwork device is possible.

It can also be advantageous if the formwork panels can be connected 40 to one another via at least one hinged articulation. In this way, the 2 WO 2014/174432 A1 transfer of the formwork panels from the unfolded into the folded state and thus their handling can also be further simplified.

It can also be favourable if each of the formwork panels has at least one suspension roller and/or at least one first support roller and/or at least one second support roller. By means of the suspension roller the formwork panels can be moved more easily into the battery formwork. During fitting, the formwork panels with the first support roller and/or with the second support roller rest on a base. These formwork panels can be moved more easily on the base with the aid of the support rollers. Furthermore, the transfer of the interconnected formwork panels from an unfolded state into a folded state or from a folded state into an unfolded state is assisted by the first support roller. During transfer of the connected formwork panels from the unfolded into the folded state or from the folded into the unfolded state, the first support roller is at least partially supported on the base and rolls along this at least temporarily. In this way, the handling of the formwork device can be further simplified.

Furthermore, it can prove advantageous if the suspension roller is provided on a narrow side of the formwork panel and preferably in the region on which the two formwork panels adjoin one another. With such a construction the suspension of the formwork panel in the battery formwork can be further simplified.

In addition, it can be advantageous if the first support roller is arranged on the longitudinal side of the formwork panel opposite the hinged articulation. In this way, the transfer of the formwork panels from an unfolded state into a folded state or from a folded state into an unfolded state can be even better supported and therefore simplified.

In an advantageous further development of the invention, the second support roller can be arranged on the formwork rear face of the formwork panel. As a result, the formwork panel can be moved more easily on a base with the result that handling can be made even easier.

It can also be favourable if the first support rollers and/or the second support rollers are arranged offset with respect to one another from the formwork panels of the formwork device along the pivot axis. In the folded state the formwork rear faces of the formwork panels on which the second support rollers are attached are facing one another. As a result of the offset arrangement of the support rollers, the spacing of the two formwork panels in the folded state can be reduced. The offset 3 WO 2014/174432 A1 arrangement of the first support rollers also enables a smaller spacing of the two formwork panels in the folded state.

It can also be favourable if the first support roller and/or the second support roller is pivotable. In this way the formwork can be moved more easily on the base.

It can also prove advantageous if the suspension roller consists of steel at least in sections and/or the first support roller and/or the second support roller consist of plastic at least in sections. Thus, the formwork panels can be moved more easily with at the same time high stability of the suspension roller or the support rollers.

In an advantageous further development of the invention, the formwork device can be supported preferably movably via the first support rollers at least temporarily during the unfolding and/or unfolding and/or raising from and/or placement on a base. As a result of the supporting of the formwork device, the handling of formwork device during the unfolding and/or unfolding and/or raising from and/or placement on a base can be further simplified.

In addition, the above object is solved by a battery formwork comprising at least one formwork device according to the invention in which the formwork panels can be inserted into the battery formwork in the connected or disconnected state.

This solution has the advantage that the production process can be more flexible. In particular, the formwork panels can be fitted in the disconnected state and also inserted into the battery formwork in this state. The dimensions of disconnected formwork panels are substantially smaller than those of formwork panels. Since disconnected formwork panels can also be inserted into the battery formwork, it is no longer necessary to connect the formwork panels before inserting into the battery formwork.

Thus, the handling can be further simplified and the space requirement further reduced.

It can also be advantageous if the formwork panels inserted in the disconnected state can be connected to one another. In this way, the handling of the formwork panels in the battery formwork can be further simplified.

It can furthermore be advantageous if the formwork panels are arranged suspended in the battery formwork since the space requirement can thus be further reduced.

It can also prove advantageous if the battery formwork has at least one carrying device, preferably a rail, for receiving the suspension 4 WO 2014/174432 A1 roller of the formwork panel. In this way, the handling can be even further simplified.

The invention will be explained in detail hereinafter with reference to an exemplary embodiment and relevant drawings.

In these drawings: Figure 1 shows a schematic view of a known battery formwork with formwork devices; Figure 2 shows a schematic view of a formwork device according to the invention in an unfolded state in a plan view; Figure 3 shows an enlarged schematic view of a hinged articulation of the formwork device from Figure 2; Figure 4 shows a schematic view of the formwork device from Figure 2 in a side view; Figure 5 shows a schematic view of the formwork device according to the invention in a raised state; and Figure 6 shows a schematic view of the formwork device according to the invention in the folded state in the battery formwork.

Figure 1 shows a schematic view of a battery formwork 1 with formwork devices 5’ as is known from DE 10 2015 209 157. The battery formwork 1 is used to produce components not shown and in particular precast concrete parts for buildings. The battery formwork 1 has a supporting framework 2 with spaced-apart supporting sections 3. The number of supporting sections 3 in Figure 1 should only be seen as an example and can be adapted to the circumstances. Furthermore, the battery formwork 1 comprises two carrying devices 4 in which the bulkheads 6 and the formwork devices 5’ are received in a suspended and movable manner, i.e. in the present embodiment displaceably. The formwork devices 5’ are in this case located between the bulkheads 6. A cavity to be filled with concrete is formed between at least one bulkhead 6 and a formwork device 5’, wherein preferably the formwork device 5’ carries formwork elements which are not shown, which determine the contour of the precast concrete parts. The formwork elements can, for example, delimit door or window cut-outs and additionally seal the cavity filled with concrete during the concreting. The formwork elements can for example be fastened to the formwork device 5’ with magnetic holders. In addition, a heating device not shown and/or a shaker not shown can also be mounted on the formwork device 5. The formwork device 5’ shown in Figure 1 is plate-shaped. The formwork device 5’ can be provided with corresponding formwork elements on one side or both sides. If the formwork device 5’ is provided with 40 formwork elements on both sides, this can serve to produce different WO 2014/174432 A1 precast concrete parts on each side. The formwork device 5’ fitted with formwork elements on both sides and also the formwork device 5’ fitted on one side is inserted between two bulkheads 6 and braced with these during the concreting.

The number of carrying devices 4 of the bulkheads 6 and the formwork devices 5’ should only be seen as an example and can be varied according to the circumstances. Thus, for example, formwork devices 5’ can be provided for the outer walls, inner walls, the base and for the roof of a house so that the components for a complete building can be produced simultaneously with the battery formwork 1. The bulkheads 6 and the formwork devices 5’ are braced between two support devices 7. The number of support devices 7 should also be seen only as an example and can be varied according to the requirements. At least one support device 7 is movably received in the carrying devices 4, i.e. displaceably in the present embodiment. For stabilization the formwork devices 7 can be connected to one another and braced in the concreting position by one or more rod-shaped connecting devices 9. The number of connecting devices 9 can be adapted to the conditions. Instead of rod-shaped connecting devices 9, hydraulic connecting devices are also possible. However, the rod-shaped connecting devices 9 are particularly robust and easy to handle.

Furthermore the battery formwork 1 has a lifting device 8 by means of 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’ can be conveyed by means of a formwork device 5’ located in the concreting position in a direction substantially perpendicular to the raising direction X. In the battery formwork 1 the formwork devices 5’ are suspended from above in the carrying devices 4 so that they are spaced apart from the base in the suspended state in the concreting position between the bearing sections 3. The design of the lifting device 8 can be adapted to the requirements. If necessary, several lifting devices 8 can be used.

The lifting device 8 is movable on two spaced-apart guide devices which are configured as running rails 25 in a tensioning direction of the formwork devices 5. Furthermore the guide devices 25 are arranged above the carrying devices 4 and parallel thereto. In order to make the battery formworks 1 more compact, the formwork devices 5 are fastened to the carrying devices 4 at the upper end thereof.

The battery formwork 1 can comprise at least one weighting device 40 with a cavity which can preferably be filled with sand, water and/or 6 WO 2014/174432 A1 concrete. Furthermore, the weighting device can be emptied and/or removed.

As a result the stableness and stability of the battery formwork can be increased.

Figures 2 shows a schematic diagram of a formwork device 5 according to the invention in a plan view, which for example can be used in the battery formwork 1 shown in Figure 1 instead of the formwork device 5’. The formwork device 5 comprises two formwork panels 10, which can be connected releasably to one another in an articulated manner in order to be transferred from an unfolded state into a folded state. In Figure 2 the formwork panels 10 are connected to one another and in an unfolded state. The plan view of Figure 2 shows the formwork front face 11 for attachment of formwork elements not shown. Furthermore, the formwork panel 10 has a formwork rear face 12 which is arranged opposite the formwork front face 11. In the folded state shown in Figure 6 the formwork rear faces 12 of the two formwork panels 10 are facing one another. The formwork device 5 is provided to be positioned between the bulkheads 6. The formwork device 5 or the formwork panel 10 can be fitted horizontally. Furthermore, the formwork device 5 or the formwork panel 10 can be transported in so-called circulating systems with conveyor devices.

Further processing stations can be located in the circulating systems.

After demoulding, the formwork device 5 or the formwork panel 10 can be cleaned for example at a work station and re-fitted at another work station before it is suspended again in the battery formwork 1.

The formwork panels 10 are substantially rectangular and are connected to one another on the longer longitudinal side 13 via two hinged articulations 15. The arrangement and number of the hinged articulations 15 should only be seen as an example and can be adapted to the circumstances. Figure 3 shows a hinged articulation 15 from Figure 2 in an enlarged view. This will be discussed in further detail subsequently.

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 on which the two formwork panels 10 adjoin one another. Each formwork panel 10 has two first support rollers 19 on the longitudinal side 13 of the formwork panel 10 opposite the hinged articulations 15. Two second support rollers 20 are each arranged on the formwork rear face 12 of the formwork panels 10. The first support rollers 19 and the second support rollers 20 of the formwork panels 10 of 40 the formwork device 5 are arranged offset with respect to one another 7 WO 2014/174432 A1 along the pivot axis 22. As a result of this arrangement, the spacing of the two formwork panels 10 in the folded state can be reduced.

In Figure 2 in the upper formwork panel 10 the two first support rollers 19 are each arranged at the edge of the formwork panel 10. This enables an easy handling of the formwork panel 10 or the formwork device . However, the number and arrangement of the suspension rollers 18, the first support rollers 19 and the second support rollers 20 can be seen as only an example and can be adapted to the respective requirements.

The suspension rollers 18 are fastened by means of holders 21b to the narrow sides 14 of the formwork panels 10 in such a manner that they protrude from the formwork panels 10.

Furthermore, the first support rollers 19 are fastened by means of holders 21a to the longitudinal sides 13 of the formwork panels 10 in such a manner that they protrude therefrom.

It is also feasible that the first support rollers 19 and/or the second support rollers 20 are pivotable with the result that the movement of the formwork panels 10 on a base 23, as shown in Figure 5, is even easier.

It has proved to be particularly favourable if the suspension roller 18 consists of steel, at least in sections and the first support rollers 19 and the second support roller 20 consist of plastic at least in sections. However, any other suitable material can also be used.

The roller axes 24a for the first support rollers and 24b for the suspension rollers 18 are shown in Figure 2.

Figure 3 shows an enlargement of a hinged articulation 15, as shown in Figure 2. Hinged articulation parts 16 are arranged on the formwork panels 10 which are interconnected by a bolt 17. In the connected state respectively one hinged part 16 of one formwork element 10 lies opposite a hinged part 16 of another formwork element 10. The bolt 17 is secured against falling out in a suitable manner. After removing the securing which is not shown, the bolt 17 can be removed from the hinged articulation parts 16 so that the formwork panels 10 can be separated from one another and can be fitted separately from one another. The hinged articulation 15 should only be seen as an example. Other suitable hinged articulations can also be used. Instead of hinged articulations, other suitable articulated types or connection or a mixture of various articulated types of connection are also feasible.

Figure 4 shows a formwork device 5 according to the invention in the connected and unfolded state in a side view. The first support 40 rollers 19 and the second support rollers 20 are supported movably on the 8 WO 2014/174432 A1 base 23. Formwork elements, not shown, which determine the contour of the precast concrete part can be applied to the formwork front face 11 of the formwork panel 10. The formwork elements can, for example, delimit door or window cut-outs and additionally seal the cavity filled with concrete during the concreting. The formwork elements can, for example be fastened to the formwork panels 10 by means of magnetic holders. Other fastening methods are also possible. The formwork panels can be designed according to the desired fastening method.

Figure 5 shows a schematic view of the formwork device 5 according to the invention during transfer from an unfolded state into a folded state or during transfer from a folded state into an unfolded state or during raising from the base 23 or placement on the base 23. The two formwork panels 10 are interconnected via hinged articulations 15. The formwork device 5 is movably supported temporarily via the first support rollers 19 during unfolding and/or unfolding and/or raising and/or placement on the base 23. As a result the handling of the formwork device can be substantially simplified.

Figure 6 shows a schematic view of the formwork device 5 according to the invention in the folded state or in a state when it is suspended in the carrying device 4 of the battery formwork 1. Figure 6 only shows the carrying device 4 of the battery formwork 1. The formwork panels 10 are interconnected in an articulated manner via the hinged articulations . The suspension rollers 18 are arranged in the carrying device 4. The formwork rear faces 12 of the formwork panels 10 are arranged adjacent to one another.

According to the present invention however, the formwork panels 10 are suspended in the battery formwork 1 not only in the connected state but also in the disconnected state. A suspension using the suspension rollers 18 is not absolutely essential. The formwork panels 10 or the formwork device 10 can also be inserted in the battery formwork 1 by other suitable methods. Furthermore, the formwork panels 10 inserted in the disconnected state can also be connected to one another in the battery formwork 1. In this way, the production process can be designed very flexibly and the handling is simplified.

As a result of the suspended arrangement of the formwork panels 10 in the battery formwork 1, the battery formwork 1 can be made more compact.

With the aid of the formwork device 5 according to the invention for a battery formwork 1 or the battery formwork 1 with a formwork device 40 5 according to the invention, it is easier for formwork panels 10 to be 9 WO 2014/174432 A1 fitted by persons or machines. Thus, the production process can be made more flexible. In particular, when the formwork panels 10 are fitted separately, it is easier to handle the same. A person or machine can more easily approach the formwork panel 10 for fitting from all sides. In addition, less space is required in production lines. 40
