- the invention further relates to a battery formwork which has two bulkheads and a formwork device that can be arranged between the bulkheads.
- the invention relates to a method for producing a precast concrete part, as well as a method for preparing the production of a precast concrete part.
- WO 2016/184947 A1 shows a battery formwork with a support device into which formwork devices are suspended from above. These formwork devices each have two formwork panels which are articulated to one another on one longitudinal side in order to be transferred from an unfolded state to a folded state. Each formwork panel has a formwork front side for attaching formwork elements and a formwork back side, with the formwork backsides of the formwork panels facing each other in the folded state of the formwork device.
- the formwork devices are fitted on an underground in the unfolded state, with formwork elements being attached to the upwardly facing formwork fronts of the horizontally aligned formwork panels. Then the formwork equipment is lifted using a lifting device. lifted, whereby the rear side of the formwork panels fold up.
- the shuttering panels are positioned between two bulkheads in such a way that cavities are formed between the shuttering fronts, the shuttering elements and the bulkheads, which are filled with concrete.
- the precast concrete parts can be hardened within the battery mold.
- the disadvantage here is that the entire battery mold is in use until the concrete has hardened and cannot be used for pouring further precast concrete parts.
- the object of the present invention is to alleviate or remedy at least individual disadvantages of the prior art.
- the aim of the invention is, in particular, to enable the battery mold to be reused more quickly and to simplify the removal of the precast concrete parts.
- a further goal can be to make it easier to transfer the formwork elements into the lying state for equipping them with limiting elements for doors, windows, etc.
- the formwork device has a spreading device for spreading apart from the second end areas of the formwork elements, which are opposite to the first end areas from the standing state of the formwork elements.
- This formwork device can be used especially in a battery formwork with two bulkheads.
- the two preferably rectangular formwork elements are each connected in a pivotable manner at a first end region, in particular on one of their longitudinal sides.
- an articulated connection between the first end regions of the formwork elements can be provided.
- the two formwork elements can be transferred from a standing state, in which the formwork elements are preferably aligned essentially vertically, to a lying state, in which the formwork elements are preferably aligned essentially horizontally.
- the first end areas form the upper ends of the formwork elements and the second end areas form the lower ends of the formwork elements.
- the formwork elements can be arranged in the standing state between the two bulkheads of the battery formwork.
- the formwork elements are in the folded-up state (i.e. they are essentially parallel to each other), with the formwork fronts pointing outwards and the formwork backs facing each other.
- the two front sides of the formwork delimit cavities into which concrete can be poured.
- the lying state of the shuttering elements can be used to attach shuttering elements, ie in particular limiting elements for door and / or window cutouts in the component, to the shuttering fronts of the Schalungsele elements.
- the spreading device according to the invention at the second end areas of the formwork elements can advantageously fulfill different functions depending on the execution.
- the formwork device After the precast concrete parts have been poured into the cavities, the formwork device, together with at least one component on a formwork front, in particular two components on the two formwork fronts, can be removed from the interior of the battery.
- the formwork is removed, in particular lifted out with a lifting device.
- the precast concrete parts are in a hardened, but not yet completely dried state, which allows the component to be held on the respective front side of the formwork without counterpressure from the bulkheads (or other formwork devices).
- the formwork device can be arranged in a drying position with the second end areas of the formwork elements spread apart outside the space between the battery formwork.
- the spreading device engages at least during the shutdown of the shuttering device with the component to be dried on the underground at the second end regions - opposite the pivotable connection between the shuttering elements.
- the second end regions of the formwork elements are spread apart so that the two formwork elements in the drying position in the side view ge form an inverted V-shape.
- the drying position is a stable intermediate position between the standing and lying position of the formwork elements.
- the formwork device can thus be arranged in the stable and space-saving drying position outside the interior of the battery formwork in order to dry the components. Meanwhile, the interior of the battery mold can already be used for the manufacture of further components.
- the spreading device In the drying position, the spreading device has the effect that the second end regions of the formwork elements are secured against collapsing into the standing state and / or unfolding into the lying state.
- the spreading device first drives the second end regions of the formwork elements apart and then holds the formwork elements in the drying position.
- the drying position is preferably closer, in particular several times closer, to the standing state than to the lying state of the formwork elements in relation to the pivoting angle.
- This implementation has the particular advantage that lifting the component away from the formwork device after drying is made much easier because the component is only exposed to low loads and, moreover, a disadvantageous tumbling of the component is avoided.
- the spreading device can also be used to transfer the formwork elements from the standing state in the direction of the lying state. A manual unfolding of the formwork elements can advantageously be avoided.
- the location and direction information such as “above”, “below”, “horizontal”, “vertical”, refer to an intended operating position of the Schalungsein direction and the battery position on a horizontal underground.

- the force deflection device has two lever elements which are connected to one another via a swivel bearing with a swivel axis that is preferably essentially stationary when the formwork elements are spread apart.
- the second end areas of the formwork elements can be spread apart particularly easily.
- the impact of the spreading device attached to the second Endbe rich on the ground or the lowering of the formwork elements on the spreading device located on the ground is converted into a pivoting of the Hebelele elements, which causes the second end regions of the formwork elements to spread apart.
- the two lever elements are preferably connected to one another in a pivotable manner by means of a pivot axis on the side of the underground.
- the spreading device in particular its lever elements, can be made of different materials.

- the lever elements have receiving troughs for receiving corresponding guide elements, in particular guide bolts, on the second end areas of the formwork elements.
- formwork elements can be precisely aligned with respect to the spreading device. This design is particularly suitable when the spreading device is initially arranged separately, i.e. at a distance from the formwork elements on the ground and the formwork elements are then lowered onto the spreading device in order to remove the second end areas from one another by means of the spreading device.
- a tensioning device in particular a spring, is provided for biasing the lever elements in the direction of a rest position of the lever elements before the second end regions of the formwork elements are spread apart.
- the spring is tensioned by the spreading of the second end regions.
- the lever elements are relaxed in the vertical position and can accommodate the formwork elements in the standing position.
- the lever elements are moved into the horizontal position against a spring force of the spring, so that the energy released by the lowering movement of the formwork elements is absorbed by the spring in order to tension it.

Due to the stationary pivot axis 22 of the Hebelele elements 20 of the spreading device 18 and the articulated connection between the lever elements 20 and the connecting elements 16 in the second end area 15 of the formwork elements 11, the formwork elements 11 are spread apart in the second end areas 15 when they are lowered. As a result, the lowering movement of the formwork elements 11 is converted into the spreading apart of the second end regions 15 of the formwork elements 11 when they are arranged on the ground. The formwork elements 11 are lowered and spread until the connecting elements 16 of the formwork elements 11 rest on the ground.
- the lever elements 20 are aligned horizontally so that the two lever elements 20 enclose an angle of 180 °. This prevents the formwork elements 11 from spreading further apart, so that the formwork device 2 assumes a stable drying position and the lifting device 9 can be removed without the formwork device 2 tipping over.
- FIG. 5 shows a further spreading device 18 according to the invention, which has a force deflection device 19 with two lever elements 20, which are connected to one another via a pivot bearing 21 with an essentially stationary pivot axis 22 when the formwork elements 11 are spread apart.
- the Hebelele elements 20 are here substantially longer than in the embodiment of FIGS. 2 to 4.
- the lever elements 20 have receptacles 25 for receiving corresponding guide bolts on the second end regions 15 of the formwork elements 11 (cf. FIG. 7).
- the spreading device 18 has an opening device 26 for transferring the formwork elements 11 from the spread apart state of the second end regions 15 into the lying state of the formwork elements 11.
- the opening device 26 comprises a guide track 27 for guiding support elements 28 on the second end regions 15 of the formwork elements 11, the guide track 27 having two sloping transfer sections 29 for transferring the support elements 28.
- the spreading device 18 has a tensioning device 30 which has a spring.
- the Clamping device 30 is used to bias the lever elements 20 in the direction of a rest position of the lever elements 20 before the second end regions 15 of the formwork elements 11 are spread apart. This can support the erection of the formwork elements 11 when moving from the lying position to the standing position.
- the two rod-shaped lever elements 20 form a V, the receiving troughs 25 being arranged at the ends of the lever elements 20, which are arranged at the V above.
- the two lever elements 20 enclose an angle between 15 and 25 °, preferably 20 °.
- the 7 of the Sp Schwarzvorrich device 18 has a releasable locking device 31 for locking the United pivoting of the lever elements 20 in their rest position.
- the locking device 31 has a hook 32 and a corresponding receiving device 33 for receiving the hook 32. Since the hook 32 is arranged on one of the two lever elements 20 and the receiving device 33 is arranged on the other of the two lever elements 20.
- the hook 32 is rotatably mounted on the one lever element 20 via a pivot bearing 34. When the hook 32 is received in the receiving device 33, the lever elements 20 are locked together so that they cannot be moved downward in opposite directions. By releasing the Ha kens 32 from the corresponding receiving device 33, the lever elements 20 can be moved against each other.
- a Kop pelstab 35 is arranged, which is connected to a compression spring 36.
- the compression spring 36 extends into the receptacle 25 of the lever element 20, on which the hook 32 is arranged, so that when the guide pin is received in the receptacle 25, the compression spring 36 is actuated, whereby the coupling rod 35 connected to the compression spring 36 via the Pivot bearing 34 releases the hook 32 from the receiving device 33.
- the shuttering elements 11 of a shuttering device 2 according to the invention can be transferred into the lying state.
- two spreading devices 18 according to the embodiment in FIG. 5 are arranged on a substrate in such a way that the guide tracks 27 of the spreading devices 18 are aligned parallel to one another.
- the formwork elements 11 are arranged in such a way that the bolts 23, which are fastened in the bores of the connecting elements 16 and are provided as guide bolts, are positioned directly above the receiving recess 25 of the spreading devices 18. Then who, as shown in Fig. 7, lowered the formwork elements 11 onto the spreading devices 18, so that the bolts 23 of the formwork elements 11 of the receiving troughs 25 of the spreading devices 18 are received.
- the formwork elements 11 each have two bolts 23, so that the total of four bolts 23 of the formwork elements 11 are received in a total of four receiving depressions 25 of the two spreading devices 18.
- the total of four support elements 28 of the two formwork elements 11 are support bolts which are arranged above the two guide tracks 27 when the connecting elements 16 and the bolts 23 are received in the receiving troughs 25 of the spreading devices 18.
- the support elements 28 can be designed as support rollers.
- the total of four transfer sections 29 of the two guide tracks 27 are arranged in such a way that when the second end regions 15 of the formwork elements 11 are lowered and spread apart, the support elements 28 of the formwork elements 11 rest on the transfer sections 29 of the guide tracks 27. With further lowering of the formwork elements 11, they are spread further apart by guiding the support elements 28 on the guide tracks 27, wherein the bolts 23 from the receiving troughs 25 of the Sp Schwarzvorrich lines 18 move.
- the formwork elements 11 are moved by means of the guide tracks 27 of the opening devices 26 from the spread apart state of the second end regions 15 into the lying state of the formwork elements 11.
- the formwork elements 11 can be cleaned and reloaded a fold.
