DETAILED DESCRIPTION
[0044] FIG. 1 shows a schematic representation of a battery mould 1 with formwork devices 2 known, for example, from WO 2017/174432. The battery mould 1 is used for the manufacture of construction elements (not shown in FIG. 1) and in particular, precast concrete elements for buildings. The battery mould 1 comprises a carrying structure 3 with distanced support sections 4. The number of support sections 4 in FIG. 1 is only to be regarded as an example and can be adapted to the circumstances. Furthermore, the battery mould 1 comprises two support devices 5, in which the bulkhead partitions 6 and the formwork devices 2 are held in a suspended and moveable manner, i.e., in the present embodiment shiftable. The formwork devices 2 are located between the bulkhead partitions 6. Between at least one bulkhead partition 6 and a formwork device 2, a cavity to be filled with concrete is formed, wherein the formwork device 2 can support formwork units not shown, which may determine the contour of the precast concrete element. The formwork units can, for example, delimit door cut-outs or window cut-outs and also seal the cavity filled with concrete during concreting. The formwork units can, for example, be attached to the formwork device 2 using magnetic holders. In addition, a heating device (not shown) and/or a vibrator (not shown) can also be mounted on the formwork device 2. The formwork device 2 is inserted between two bulkhead partitions 6 and clamped with them during concreting. The number of support devices 5 of the bulkhead partitions 6 and of the formwork devices 2 is to be regarded merely as an example and can be varied depending on the circumstances at hand. For example, formwork devices 2 can be provided for concreting the outer walls, interior walls, the floor and the roof of a house so that, with the battery mould 1, the construction elements for an entire building can be produced simultaneously. The bulkhead partitions 6 and the formwork devices 2 are clamped between two support devices 7. The number of support devices 7 is also to be regarded as merely an example and can be varied according to the requirements. At least one support device 7 is held in the support devices 5 in a moveable manner, i.e., in the present embodiment, being shiftable. For stabilisation in the concreting position, the formwork devices 2 and the support devices 7 can be connected with each other and clamped by one or a plurality of rod-shaped connecting devices 8. The number of connecting devices 8 can be adapted to the conditions at hand. Instead of rod-shaped connecting devices 8, hydraulic connecting devices are also possible. However, the rod-shaped connecting devices 8 are particularly robust and easy to handle. Furthermore, the battery mould 1 comprises a lifting device 9, with which at least one of the formwork devices 2 can be transferred from the lowered concreting position into a raised transport position, in which the formwork device 2 can be conveyed above a formwork device 2 located in the concreting position in a direction essentially perpendicular to the lifting direction. In the case of the battery mould 1, the formwork devices 2 are hung from above into the support devices 5 so that they are distanced from the floor in the suspended state in the concreting position between the support sections 4. The design of the lifting device 9 can be adapted to the requirements. If necessary, a plurality of lifting devices 9 can also be used.
[0045] The lifting device 9 is moveable on two distanced guide devices 10, which are designed here as running rails, in a clamping direction of the formwork devices 2. Furthermore, the guide devices 10 are arranged above the support devices 5 and parallel thereto. In order to make the battery moulds 1 more compact, the formwork devices 2 are attached to the support devices 5 at their upper end.
[0046] Instead of the known formwork devices 2, the formwork devices 2 according to the disclosure can be received in the battery mould 1, which are explained in the following on the basis of FIGS. 2 to 4.
[0047] FIG. 2 shows a plurality of formwork devices 2, which are set up, in particular, for the arrangement between two bulkhead partitions 6 of the battery mould 1 in accordance with FIG. 1. The formwork device 2 comprises two formwork elements 11, which are formwork panels in the embodiment shown. The formwork elements 11 each comprise a formwork front side 12 for concrete to be applied and a formwork rear side 13. The formwork elements 11 are pivotably connected to each other at first end regions 14 via joints 15 so that the opposite second end regions 16 (cf. FIG. 5) can be moved apart in order to transfer the formwork device 2 from a standing state into a lying state. Between two formwork devices 2, another formwork element 17 is arranged, onto which concrete can be applied on the opposite outer surfaces. Thus, individual formwork chambers 18 are formed between the front side of the formwork element 11 and the outer surface of the other formwork element 17, which outer surface of the other formwork element 17 faces the front side of the formwork element 11.
[0048] As can be seen from FIGS. 2 to 4, before casting a construction element 19, a transport anchor 20 is detachably attached to the respective formwork element 11 of the formwork device 2. The transport anchor 20 comprises a connecting part 21, whichas will be explained in more detail below on FIGS. 4 to 6can be connected to a lifting device 22. In addition, the transport anchor 20 comprises a shear force part 23, which extends essentially perpendicular to the connecting part 21 essentially across the entire thickness of the formwork chamber 18 (and thus of the construction element 19 to be manufactured). With the shear force part 23, shear forces can be introduced perpendicularly to the main extension plane of the construction element 19.
[0049] As can best be seen from FIG. 3, the transport anchor 20 comprises a first connecting element 24, with which the transport anchor 20 can be detachably engaged with a corresponding connecting element 25 on the formwork element 11. In the embodiment shown, the first connecting element 24 of the transport anchor 20 comprises a first threaded part, here a threaded bolt 26, which can be connected to a second threaded part on the formwork element 11, here a nut 27. The shear force part 23 comprises a passage opening 28, which extends over the entire length of the shear force part 23, seen in the thickness direction of the construction element 19. Thus, the first connecting element 24 can be plugged in from the outside through the passage opening 28 of the shear force part 23 to establish the connection with the corresponding connecting element 25 on the formwork element 11. In the embodiment shown, the shear force part 23 comprises a cylindrical shear force sleeve 29 in the middle range. At the first end of the shear force sleeve 29 (on the side of the formwork element 11), a first cross-sectional widening 30 is formed, and, at the second end of the shear force sleeve 29, a second cross-sectional widening 31 is formed.
[0050] As can be seen from FIG. 4 further, the connecting part 21 comprises a connection sleeve 32 (in the upper area conically expanding upwards), which is immovable, but detachable where applicable, connected to the shear force part 23 in order to achieve a power transmission from the connection sleeve 32 to the shear force part 23. On the connection sleeve 32, an internal thread is formed, which allows the attachment of the lifting device 22 (see FIG. 5). In the embodiment shown, an anchor bolt 33 is also provided, which protrudes from the shear force part 23 inwards, away from the front side for the attachment of the lifting device. In an embodiment, the anchor bolt 33 essentially extends in a line with the connection sleeve 32. The anchor bolt 33 improves the dissipation of longitudinal or tensile forces into the construction element 19.
[0051] In addition, the transport anchor 20 comprises a second connecting element 34, which is set up for the connection of a support element 35, for example, a set-up support (see FIG. 9). This function will be explained in more detail below using FIG. 9. The second connecting element 34 is, in particular, a threaded element, here a threaded sleeve with an internal thread, into which a screw on the set-up support is screwed.
[0052] As can be seen from FIG. 5, the formwork device 2 can be brought after casting the construction element 19 in a partially unfolded, triangular drying position at the base 36. After the complete curing of the construction element 19, the construction element 19 can be removed from the formwork device 2. For this purpose, the lifting device 22 is detachably attached to the transport anchor 20 of the construction element 19. By actuating the lifting device 22, the construction element 19 is lifted away from the formwork device 2 (cf. FIG. 6, 7). The construction element 19 can then be placed lying on floor 36 with the lifting device 22. FIG. 8 shows different phases when folding the construction element 19 from the standing state (far left) into the lying state at the floor 36 (far right). The transport anchor 20 ensures a reliable dissipation of the shear forces when the large-format construction elements 19 are placed.
[0053] FIG. 9 shows the construction element 19 in a standing state at the place of construction of a building consisting of a plurality of construction elements. The transport anchor 20 is used for the temporary attachment of a support element 35, with which the construction element 19 can be supported in an upright, standing state.
[0054] FIGS. 1-9 show example configurations with relative positioning of the various components. If shown directly contacting each other, or directly coupled, then such elements may be referred to as directly contacting or directly coupled, respectively, at least in one example. Similarly, elements shown contiguous or adjacent to one another may be contiguous or adjacent to each other, respectively, at least in one example. As an example, components laying in face-sharing contact with each other may be referred to as in face-sharing contact. As another example, elements positioned apart from each other with only a space there-between and no other components may be referred to as such, in at least one example. As yet another example, elements shown above/below one another, at opposite sides to one another, or to the left/right of one another may be referred to as such, relative to one another. Further, as shown in the figures, a topmost element or point of element may be referred to as a top of the component and a bottommost element or point of the element may be referred to as a bottom of the component, in at least one example. As used herein, top/bottom, upper/lower, above/below, may be relative to a vertical axis of the figures and used to describe positioning of elements of the figures relative to one another. As such, elements shown above other elements are positioned vertically above the other elements, in one example. As yet another example, shapes of the elements depicted within the figures may be referred to as having those shapes (e.g., such as being circular, straight, planar, curved, rounded, chamfered, angled, or the like). Further, elements shown intersecting one another may be referred to as intersecting elements or intersecting one another, in at least one example. Further still, an element shown within another element or shown outside of another element may be referred as such, in one example.
[0055] The following claims particularly point out certain combinations and sub-combinations regarded as novel and non-obvious. These claims may refer to an element or a first element or the equivalent thereof. Such claims should be understood to include incorporation of one or more such elements, neither requiring nor excluding two or more such elements. Other combinations and sub-combinations of the disclosed features, functions, elements, and/or properties may be claimed through amendment of the present claims or through presentation of new claims in this or a related application. Such claims, whether broader, narrower, equal, or different in scope to the original claims, also are regarded as included within the subject matter of the present disclosure.
