[0001] HANDLING DEVICE FOR LIFTING AND / OR SWINGING

[0002] OF CONCRETE BODY AND CONCRETE BODY FOR USE IN CONNECTION WITH SUCH A HANDLING DEVICE

[0003] Description

[0004] The present invention relates to a handling device for lifting and / or pivoting or swiveling concrete bodies, in particular precast concrete elements, as well as concrete bodies, in particular precast concrete elements, for use in conjunction with such a handling device. Furthermore, the present invention relates to a molding device for producing such concrete bodies, in particular precast concrete elements.

[0005] background

[0006] It is known in the prior art to produce precast concrete elements, such as tubular concrete products, in high quality using a casting process in a stationary formwork, especially in an automated process where the precast concrete elements can be manufactured automatically using a cost-effective and high-quality casting process.

[0007] In this context, prior art has proposed automated systems for the production of tubular concrete products, in particular concrete pipes, in which concrete products are transported in a circulation system between individual automated production stations of a production area by means of a form conveyor device and are produced in a casting process, in a program-controlled and timed manner in an at least partially automated production cycle.

[0008] Such a system is described, for example, in DE 10 2012 217 324 A1, where the system comprises a production area with a plurality of fully automated production stations and a mold conveying device for transporting the molds or the outer mold and the mold core (as an exemplary inner mold) of molds between the production stations. Another such system is described, for example, in DE 10 2016 202 411 A1.

[0009] In this process, a wide variety of precast concrete elements can be manufactured using a casting process in an automated production system, typically exhibiting different shapes and sizes. Furthermore, these precast concrete elements are manufactured in an upright position during the casting process and therefore usually need to be not only lifted and set down at the production system and / or at the installation site, but also rotated from their upright position into their installation position, typically by 90° from a standing position to a horizontal position corresponding to the installation position.

[0010] In this context, it is an object of the present invention to provide a simple, efficient and / or reliable technical solution for handling precast concrete elements of various sizes and / or shapes, with which the precast concrete elements can be lifted, set down and / or pivoted simply, efficiently and / or reliably, in particular from a standing position to a lying installation position.

[0072] Detailed description of the figures and preferred embodiments

[0073] Examples and embodiments of the present invention are described in detail below with reference to the accompanying figures. Identical or similar elements in the figures may be designated with the same reference numerals, but sometimes they may be designated with different reference numerals.

[0074] It should be emphasized that the present invention is in no way limited or restricted to the embodiments and features described below, but also includes modifications of the embodiments, in particular those which are encompassed by modifications of the features of the described examples or by combining one or more of the features of the described examples within the scope of protection of the independent claims.

[0075] The present invention relates to a handling device for lifting and / or pivoting concrete bodies, in particular precast concrete elements, and some exemplary embodiments of such handling devices according to the invention, which are not to be interpreted restrictively, are described below, in particular with reference to Figs. 1, 3, 6, 7, 11, 12, 13A to 13C, 14, 16, 17, 18A to 18C, 19 and 20.

[0076] The present invention further relates to precast concrete elements, in particular precast concrete elements, for use in conjunction with such a handling device, and some exemplary embodiments of such concrete elements according to the invention, which are not to be interpreted restrictively, are described below, in particular with reference to Figures 2A and 2B, 3, 4, 6, 8A and 8B, 9A and 9B, 11, 12, 14, 15, 16, 17 and 19.

[0077] The present invention further relates to molding devices for the production of such concrete bodies, in particular precast concrete elements, and an exemplary embodiment of such a molding device according to the invention, which is not to be interpreted restrictively, is described below, in particular with reference to Figs. 5, 10A and 10B. Fig. 1 shows an exemplary schematic front view of a handling device 100 for lifting and / or turning concrete bodies 200 according to an exemplary embodiment.

[0078] The handling device 100 according to Fig. 1 is shown by way of example held on a first support section 120. In Fig. 1, the vertical direction of the exemplary handling device 100 is the direction aligned vertically with the axis Z, and the axis X shows an exemplary direction in the horizontal plane. This applies analogously to embodiments described later.

[0079] Consequently, the handling device 100 according to Fig. 1 is shown suspended from the first support section 120 only by way of example, and the first support section 120 can, in some embodiments, be held by way of example on a manipulator, for example on a crane or robot, in particular for example a gantry robot, which is not shown in Fig. 1. Such a manipulator can move the first support section 120 and thus the handling device 100 horizontally (e.g. in the X and / or Y direction) and / or vertically (e.g. in the Z direction) in some embodiments. This applies analogously to embodiments described later.

[0080] In further embodiments, the handling device 100 can also be held transversely or horizontally (e.g., with a horizontal Z-axis and a vertical X-axis or a horizontal X-axis in Fig. 1). This applies analogously to embodiments described later.

[0081] In some embodiments, the support section 120 can also be supported and / or guided by a manipulator, wherein the manipulator can preferably be configured to move the handling device 100 translationally in one, two, and up to three spatial directions and / or to rotate it in one or two rotary or pivot axes (e.g., to rotate or pivot the support section 120 about the Z-axis). Such an exemplary manipulator can be controlled manually, semi-automatically, or fully automatically, analogous to the handling device. For example, the handling device 100 can be held and / or guided by a crane or a robot, such as a 5-axis industrial robot and / or a gantry robot. Such an exemplary manipulator can also be included in the handling device according to some embodiments. This applies analogously to embodiments described later.

[0082] By way of example, a second support section 110 is held on the first support section 120; this second support section is merely an example of a beam extending in the X-direction. In Fig. 1, the handling device 100 is configured, at least by way of example, such that the handling device 100, or at least the first support section 120, is movable vertically in the Z-direction together with the second support section 110 (or at least the second support section 110). This applies analogously to embodiments described later.

[0083] By way of example, the second support section 110 carries two clamping sections 130A and 130B, which extend substantially parallel to the second support section 110 in the Z-direction. The clamping sections 130A and 130B can be configured, by way of example, to perform a closing and / or an opening clamping movement. This applies analogously to embodiments described later.

[0084] For example, the handling device 100 is configured so that the two gripper sections 130A and 130B are movable in the X-direction. Here, the gripper sections 130A and 130B can, for example, be moved towards each other in the X-direction along the support section 110 in a gripper-like manner (e.g., analogous to a closing gripper movement) and / or be moved away from each other in the X-direction (e.g., analogous to an opening gripper movement). This applies analogously to the embodiments described later.

[0085] In some embodiments, the gripper sections 130A and 130B can be moved synchronously (in opposite directions) in the X-direction, while in other embodiments it may be preferred that the gripper sections 130A and 130B can be moved independently of each other. This applies analogously to embodiments described later.

[0086] The handling device 100 includes, for example, a pair of clamping jaws with clamping jaw sections 150A and 150B, which are held opposite each other, for example, directly on the pliers sections 130A and 130B in axis A.

[0087] For example, the clamping jaw sections 150A and 150B can be driven directly by a rotary drive about axis A. The pivoting sections of clamping jaw sections 150A and 150B can, for example, be configured to rotate or pivot about axis A by preferably at least substantially 90° or, more preferably, ±90°.0 to be carried out in both directions of rotation. In some embodiments, the clamping jaw sections 150A and 150B can also be freely rotated 360° or more, preferably in both directions of rotation, around the axis A.

[0088] In some embodiments, the clamping jaw sections 150A and 150B can be rotated (rotated or pivoted) independently and synchronously around the axis, and in other embodiments it may be preferred that the rotation or pivoting of the pivoting sections 140A and 140B around the axis A can be controlled independently of each other.

[0089] The clamping jaw sections 150A and 150B form, by way of example, a pair of clamping jaws axially opposed to each other in the direction of axis A (in the X-direction). In some preferred embodiments, the clamping jaw sections 150A to 150B can be moved in the direction of axis A (in the X-direction in Fig. 1) relative to the respective gripper sections 130A and 130B; however, in some embodiments, it is sufficient if the movement in the direction of axis A (in the X-direction) is enabled by moving the gripper sections 130A and 130B. This applies analogously to embodiments described later. The handling device 100 is configured, by way of example, to allow concrete bodies (e.g., from precast concrete elements) to be handled by gripper-like clamping, particularly preferably for lifting, setting down, and / or pivoting the corresponding concrete bodies. This applies analogously to embodiments described later.The following describes this using an example of a tubular precast concrete element or concrete pipe 200.

[0090] Fig. 2A shows an exemplary schematic front view of an exemplary tubular precast concrete element 200 according to an embodiment for use with the handling device 100 according to Fig. 1. Fig. 2B shows an exemplary schematic side view of the exemplary tubular precast concrete element 200 according to Fig. 2A.

[0091] The exemplary tubular precast concrete element 200 according to Figures 2A and 2B comprises an exemplary tubular concrete main body 210, which can be manufactured, for example, according to the desired precast concrete shape and equipment, e.g., by casting using self-compacting concrete. This applies analogously to embodiments described later. The precast concrete element can have any desired dimensions (i.e., different lengths, different diameters, different profile shapes, etc.). This applies analogously to embodiments described later.

[0092] For example, the exemplary tubular precast concrete element 200 according to Figs. 2A and 2B can be manufactured using a molding device according to Fig. 5, for example by casting with self-compacting concrete. This applies analogously to the embodiments described later.

[0093] For use with the handling device 100, the exemplary precast concrete element, i.e., here by way of example the tubular precast concrete element 200, has clamping sections 221A and 221B on the outer sides of the main concrete body 210.

[0094] In some preferred embodiments, the clamping sections 221A and 221B are preferably not auxiliary components to be attached or fastened to the main concrete body 210, but rather the clamping sections 221A and 221B are preferably formed monolithically as part of the entire concrete body of the precast concrete element, i.e., in particular preferably connected to the main concrete body 210 or formed monolithically from concrete, virtually, in the case of exemplary production by casting, literally from a single casting; see also Fig. 4. This applies analogously to embodiments described later.

[0095] In the exemplary upright position (which, for example, in a casting process where the precast concrete elements are cast upright, can correspond to the manufacturing position) according to Figures 2A and 2B, the clamping sections 221A and 221B are arranged on the outer sides of the main concrete body 210 such that the clamping section 221A is located on one side (example: left in Figure 2A) of the main concrete body 210, with the vertical direction here exemplarily corresponding to the longitudinal direction of the tubular precast concrete element 200. Furthermore, the clamping section 221B is arranged exemplarily on the other side (exemplary: right in Figure 2A) of the main concrete body 210 in an exemplary horizontal direction (exemplary: transverse to the longitudinal direction) opposite the clamping section 221A. For example, the clamping sections 221A and 221B are arranged such that the clamping section 221B is opposite the clamping section 221A in the horizontal direction (e.g. in the X direction).

[0096] The clamping sections 221A and 221B form an exemplary pair of clamping sections. Here, the clamping section pair is preferably assigned to a respective pair of clamping jaws of the handling device 100. This applies analogously to the embodiments described later.

[0097] In this merely exemplary embodiment, the clamping sections 221A and 221B have, by way of example, flat outer surfaces which are preferably arranged parallel to each other and preferably, by way of example, substantially perpendicular to a direction which is oriented substantially perpendicular to the longitudinal direction of the precast concrete element 200.

[0098] On the outer surfaces of the clamping sections 221A and 221B, exemplary recesses are formed as shaped sections N, here by way of example in the form of a hexagonal recess that tapers inwards (see in particular Figs. 2B and 4). This can be used in some embodiments, e.g., when the clamping jaw sections 150A and 150B of the handling device 100 are formed as shaped sections F, for example, the shaped sections F in Fig. 1, which are formed by way of example as projections or conically tapered projections, and which are formed by way of example as hexagonal projections projecting in the X direction.

[0099] The shapes of the forming sections F on the clamping jaw sections and the corresponding forming sections N on the clamping sections on the concrete body 210 of the precast concrete element 200 are not limited to specific shapes, but are preferably designed to fit each other accordingly, preferably in particular such that the respective forming sections F on the clamping jaw sections and the corresponding forming sections N on the clamping sections on the concrete body 210 of the precast concrete element 200 are each designed to fit each other at least partially in a form-fitting manner.

[0100] This has the advantage that the clamping hold of the precast concrete element does not only have to be exerted by force, but at least a positive-locking connection component is added by means of at least a partially positive-locking (releasable) connection of the form sections F to the clamping jaw sections and the corresponding form sections N to the clamping sections on the concrete body 210 of the precast concrete element 200, so that the precast concrete element can be clamped at least partially positively, e.g., positively or force-locking and positive-locking. This can reduce the loads occurring during lifting and swiveling. This applies analogously to embodiments described later. The shape of the form sections is not limited here, and in embodiments according to Fig. 1 with one pair of clamping jaws, the form sections F and N are...N, viewed in the X direction, is preferably not rotationally symmetrical, so that a torque can be transmitted positively to pivot a clamped precast concrete element by rotating the clamping jaws. Examples of shapes include angular shapes, e.g., triangles, quadrilaterals, pentagons, hexagons (as in Figs. 1 and 2B), polygons, star-shaped, cross-shaped, etc., or round shapes, e.g., ovals, etc. More complex shapes, e.g., S-shaped, Y-shaped, T-shaped, etc., are also possible.

[0101] In exemplary embodiments, the respective forming sections F on the clamping jaw sections and the corresponding forming sections N on the clamping sections on the concrete body 210 of the precast concrete element 200 form at least partially positive-locking, detachable coupling connections that can be coupled in a direction transverse to the longitudinal direction of the precast concrete element and, in the detachably connected or coupled state, allow the precast concrete element to be lifted and / or pivoted. This preferably also applies to the following exemplary embodiments.

[0102] Fig. 3 shows an exemplary sequence of possible handling procedures for the exemplary tubular precast concrete element 200 according to Figs. 2A and 2B using the handling device 100 according to Fig. 1 in a front view. The handling device 100 is preferably moved towards the precast concrete element 200 and the clamping jaw sections are aligned at the level of the clamping sections; see, for example, Fig. 3 (i) and (ii). The clamping jaw sections, aligned vertically, can then be moved horizontally (in the X direction) towards each other, preferably until the clamping jaw sections are horizontally engaged with the clamping sections on the precast concrete element; see, for example, Fig. 3 (iii). This then enables, for example, the lifting of the precast concrete element 200, as shown in Fig. 3 (iv), the pivoting of the precast concrete element 200, as shown in Fig. 3 (v), and / or the setting down of the precast concrete element 200, e.g. in a pivoted position.Transport and / or installation position; see e.g. Fig. 3 (vi).

[0103] Fig. 4 shows an exemplary schematic representation of a cross-section of the exemplary tubular precast concrete element 200 according to Figs. 2A and 2B. This shows a section through the precast concrete element 200 at the level of the clamping sections 221A and 221B.

[0104] Preferably, the clamping sections 221A and 221B are oriented towards the center of gravity of the precast concrete element. Particularly preferably, the clamping sections 221A and 221B are arranged on the main concrete body 210 such that the center of gravity of the precast concrete element 200 is located in the area (especially viewed in the X, Y, and / or Z directions, and particularly preferably transversely to the longitudinal direction of the precast concrete element) essentially between the clamping sections 221A and 221B. This applies analogously to embodiments described later. Fig. 5 shows an exemplary schematic representation of a cross-section of an exemplary mold 500 for producing the exemplary tubular precast concrete element 200 according to Figs. 2A and 2B. The mold 500 comprises, by way of example, an (optional) inner mold, e.g., a mold core 510, and an outer mold, e.g., a mold shell 520.

[0105] The inner side of the outer mold 520 is designed as an example, the clamping sections 221A and 221B are to be formed on the outer side of the precast concrete element 200, and for this purpose the outer mold 520 of the molding device 500 includes, as an example, corresponding molding sections 521A and 521B on the inside.

[0106] Fig. 6 shows an exemplary sequence of possible handling of an exemplary, longitudinally tapered, tubular precast concrete element 300 with the handling device 100 according to Fig. 1.

[0107] The advantage of corresponding shaped sections on the outer surfaces of the precast concrete element is, in particular, that this is applicable to various sizes and shapes, especially also to precast concrete elements that taper longitudinally, for example, the longitudinally tapered precast concrete element 300 according to Fig. 6, which can be handled with the same handling device 100 according to Fig. 1 analogously to Fig. 3. Fig. 7 shows an exemplary schematic front view of a handling device 100 for lifting and / or turning concrete bodies 200 according to an embodiment.

[0108] The handling device 100 according to Fig. 7 is, by way of example, held on a first support section 120, analogous to Fig. 1. In Fig. 7, the vertical direction of the exemplary handling device 100 is the direction aligned vertically with the axis Z, and the axis X indicates an exemplary direction in the horizontal plane. This applies analogously to embodiments described later. By way of example, a further second support section 110 is held on the first support section 120, which is only by way of example designed as a beam section extending in the X direction. In Fig. 7, the handling device 100 is configured, at least by way of example, such that the handling device 100, or at least the first support section 120, is movable vertically in the Z direction together with the second support section 110 (or at least the second support section 110). This applies analogously to embodiments described later.

[0109] By way of example, the second support section 110 carries two clamping sections 130A and 130B, which extend substantially parallel to the second support section 110 in the Z-direction. The clamping sections 130A and 130B can be configured, by way of example, to perform a closing and / or an opening clamping movement. This applies analogously to embodiments described later.

[0110] For example, the handling device 100 is configured so that the two gripper sections 130A and 130B are movable in the X-direction. Here, the gripper sections 130A and 130B can, for example, be moved towards each other in the X-direction along the support section 110 in a gripper-like manner (e.g., analogous to a closing gripper movement) and / or be moved away from each other in the X-direction (e.g., analogous to an opening gripper movement).

[0111] In some embodiments, the gripper sections 130A and 130B can be moved synchronously (in opposite directions) in the X-direction, while in other embodiments it may be preferred that the gripper sections 130A and 130B can be moved independently of each other. This applies analogously to embodiments described later.

[0112] On the sides of the jaw sections 130A and 130B opposite each other in the X direction, respective swivel sections 140A and 140B are held as examples, which can be swivelled about the axis A aligned in the X direction.

[0113] The pivot sections 140A and 140B are, by way of example, configured to perform a rotation or pivoting movement about the axis A of preferably at least substantially 90° or more preferably + / -90°. 0to be carried out in both directions of rotation. In some embodiments, the pivot sections 140A and 140B can also be freely rotated 360° or more, preferably in both directions, about the axis A. This applies analogously to embodiments described later.

[0114] In some embodiments, the pivot sections 140A and 140B can be rotated (rotated or pivoted) about the axis in a dependently synchronous manner, and in other embodiments, it may be preferred that the rotation or pivoting of the pivot sections 140A and 140B about the axis A can be controlled independently of each other. This applies analogously to embodiments described later.

[0115] On the sides of the pivot sections 140A and 140B opposite each other in the X-direction, clamping jaw sections 151A to 152B are arranged as an example. Clamping jaw sections 151A and 152A are held on the pivot section 140A as an example. Clamping jaw sections 151B and 152B are held on the pivot section 140B as an example, with clamping jaw section 151B being opposite clamping jaw section 151A in the X-direction, and clamping jaw section 152B being opposite clamping jaw section 152A in the X-direction as an example.

[0116] The clamping jaw sections 151A and 151B form, by way of example, a first pair of clamping jaws, and the clamping jaw sections 152A and 152B form, by way of example, a second pair of clamping jaws. In some preferred embodiments, the clamping jaw sections 151A to 152B can be moved in the direction of axis A (in the X direction in Fig. 1); see, for example, the later embodiment according to Fig. 13A and also Fig. 18A.

[0117] The handling device 100 is designed, by way of example, to handle concrete bodies (e.g., from precast concrete elements) by means of a clamping action, particularly preferably for lifting, setting down, and / or pivoting the respective concrete bodies. This applies analogously to embodiments described later. In the following, this is described by way of example with regard to an exemplary tubular precast concrete element or concrete pipe 200.

[0118] Fig. 8A shows an exemplary schematic front view of an exemplary tubular precast concrete element 200 according to an embodiment for use with the handling device 100 according to Fig. 1. Fig. 8B shows an exemplary schematic side view of the exemplary tubular precast concrete element 200 according to Fig. 8A. Fig. 9A shows an exemplary schematic cross-section of the exemplary tubular precast concrete element 200 according to Figs. 8A and 8B. Fig. 9B shows an exemplary schematic longitudinal section of the exemplary tubular precast concrete element 200 according to Figs. 8A and 8B.

[0119] The exemplary tubular precast concrete element 200 according to Figures 8A to 9B comprises an exemplary tubular concrete main body 210, which can be manufactured, for example, according to the desired precast concrete shape and equipment, e.g., by casting using self-compacting concrete. This applies analogously to embodiments described later. The precast concrete element can have any desired dimensions (i.e., different lengths, different diameters, different profile shapes, etc.). This applies analogously to embodiments described later.

[0120] For example, the exemplary tubular precast concrete element 200 according to Figs. 8A to 9B can be manufactured using a molding device according to Figs. 10A and 10B, for example by casting using self-compacting concrete. This applies analogously to the embodiments described later.

[0121] For use with the handling device 100, the exemplary precast concrete element, i.e., here by way of example the tubular precast concrete element 200, has clamping sections 221A to 222B on the outside of the main concrete body 210.

[0122] In some preferred embodiments, the clamping sections 221A to 222B are preferably not auxiliary components to be attached or fastened to the main concrete body 210, but rather the clamping sections 221A to 222B are preferably formed monolithically as part of the entire concrete body of the precast concrete element, i.e., in particular preferably connected to the main concrete body 210 or formed monolithically from concrete, virtually, in the case of exemplary production by casting, literally from a single casting. This applies analogously to embodiments described later.

[0123] In the exemplary upright position (which, for example, can correspond to the manufacturing position in a casting process where the precast concrete elements are cast upright) according to Figures 8A and 8B, the clamping sections 221A to 222B are arranged on the outer sides of the main concrete body 210 such that the two clamping sections 221A and 222A are arranged side by side on one side (example left in Figure 8A) of the main concrete body 210 in an exemplary vertical direction (example Z-direction), where the vertical direction here exemplarily corresponds to the longitudinal direction of the tubular precast concrete element 200. Furthermore, the two clamping sections 221B and 222B are arranged side by side on the other side (example right in Figure 8A) of the main concrete body 210 in an exemplary vertical direction (example Z-direction).

[0124] For example, the clamping sections 221A to 222B are arranged such that clamping section 221B is opposite clamping section 221A in the horizontal direction (e.g., in the X-direction), and clamping section 222B is opposite clamping section 222A in the horizontal direction (e.g., in the X-direction). This applies analogously to the embodiments described later.

[0125] The clamping sections 221A and 221B form, by way of example, a first pair of clamping sections, and the clamping sections 222A and 222B form, by way of example, a second pair of clamping sections. Here, the clamping section pairs are preferably assigned to the respective pairs of clamping jaws of the handling device 100.

[0126] For example, the spacing of the respective clamping sections in the longitudinal direction of the precast concrete element 200 (here, by way of example, the Z-direction) corresponds to the spacing of the corresponding clamping jaw sections in the Z-direction or in the longitudinal direction of the pivot sections 140A / 140B (see also Fig. 11, in particular sections (iii) and (iv)). This applies analogously to embodiments described later. In further embodiments, it is alternatively or additionally possible to design or configure the handling device 100 such that the clamping jaw sections on the respective pivot sections are movable transversely to the axis A or transversely to the X-direction (i.e., in the longitudinal direction of the pivot sections), e.g., to adapt to the distance between the respective clamping sections on the precast concrete element.

[0127] In this merely exemplary embodiment, the clamping sections 221A to 222A have, by way of example, flat outer surfaces which are preferably arranged parallel to each other and preferably, by way of example, substantially perpendicular to a direction which is oriented substantially perpendicular to the longitudinal direction of the precast concrete element 200.

[0128] On the outer sides of the clamping sections 221A to 222B, exemplary recesses are formed as shaped sections N, here by way of example cylindrical or inwardly tapered recesses (see in particular Figs. 8B and 9B). This can be used in some embodiments, e.g., when the clamping jaw sections 151A to 152B of the handling device 100 are formed as shaped sections F, for example, the shaped sections in Fig. 7, which are formed by way of example as projections or outwardly tapered projections, and which are formed by way of example as cylindrical projections projecting in the X direction.The shapes of the forming sections F on the clamping jaw sections and the corresponding forming sections N on the clamping sections on the concrete body 210 of the precast concrete element 200 are not limited to specific shapes, but are preferably designed to fit each other accordingly, preferably in particular such that the respective forming sections F on the clamping jaw sections and the corresponding forming sections N on the clamping sections on the concrete body 210 of the precast concrete element 200 are each designed to fit each other at least partially in a form-fitting manner.

[0129] This has the advantage that the clamping hold of the precast concrete element does not only have to be exerted by force, but at least a positive-locking connection component is added through at least a partially positive-locking (releasable) connection of the form sections F to the clamping jaw sections and the corresponding form sections N to the clamping sections on the concrete body 210 of the precast concrete element 200, so that the precast concrete element can be clamped at least partially positively, e.g., positively or force-locking and positive-locking. This can reduce the loads occurring during lifting and swiveling. This applies analogously to the embodiments described later.

[0130] The shape of the mold sections is not limited to the aforementioned cylindrical or conical, frustoconical shapes. Other possible shapes include angular profiles, such as triangles, quadrilaterals, pentagons, hexagons (as in Figures 1 and 2B), polygons, star shapes, cross shapes, etc., or round shapes, such as ovals, etc. More complex shapes, such as S-shaped, Y-shaped, T-shaped, etc., are also possible.

[0131] In exemplary embodiments, the respective forming sections F on the clamping jaw sections and the corresponding forming sections N on the clamping sections on the concrete body 210 of the precast concrete element 200 form at least partially positive-locking, detachable coupling connections that can be coupled in a direction transverse to the longitudinal direction of the precast concrete element and, in the detachably connected or coupled state, allow the precast concrete element to be lifted and / or pivoted. This preferably also applies to the following exemplary embodiments.

[0132] Fig. 10A shows an exemplary schematic representation of a cross-section of an exemplary molding device 500 for producing the exemplary tubular precast concrete element 200 according to Figs. 8A and 8B. Fig. 10B shows an exemplary schematic representation of a longitudinal section of the exemplary molding device 500 according to Fig. 10A for producing the exemplary tubular precast concrete element according to Figs. 8A and 8B.

[0133] The molding device 500 comprises, by way of example (e.g., analogous to Fig. 5), an inner mold core 510 (which in further embodiments can also be designed, for example, as a shrink core) and an outer mold shell 520, as well as, by way of example, a mold base 530. By way of example, the molding device 500 is designed to be open at the top to allow the introduction of concrete. In further embodiments, mold lids can also be provided, which can be closed after the introduction of the concrete.

[0134] Essentially, the forming device 500 (e.g. analogous to Fig. 5) forms a negative mold of the desired concrete body of the precast concrete element, including the externally arranged clamping sections 221A to 222B; see, e.g., the forming sections 521A to 522B formed on the inside of the mold shell 520 for forming the clamping sections 221A to 222B.

[0135] Preferably, the clamping sections 221A to 222B are oriented towards the center of gravity of the precast concrete element. Particularly preferably, the clamping sections 221A to 222B are arranged on the main concrete body 210 such that the center of gravity of the precast concrete element is located in the area (especially viewed in the X, Y and / or Z directions, and particularly preferably transversely to the longitudinal direction of the precast concrete element) essentially between the clamping sections 221A to 222B. This applies analogously to embodiments described later.

[0136] In some embodiments, a pair of clamping sections is provided, as this allows the precast concrete element to be lifted. In this case, a handling device 100 with only one pair of clamping jaws is sufficient. Furthermore, this allows for force-fit turning or pivoting. Two (or more) pairs of clamping sections and corresponding two (or more) clamping jaw sections on the handling device 100 have the advantage that positive-lock assisted turning or pivoting is also possible, thus reducing stress on the precast concrete element during the pivoting process. This applies analogously to embodiments described later.

[0137] Fig. 11 shows an exemplary sequence of possible handling of the exemplary tubular precast concrete element 200 according to Figs. 8A and 8B with the handling device 100 according to Fig. 7 in a front view. Fig. 12 shows a corresponding exemplary sequence of possible handling of the exemplary tubular precast concrete element 200 according to Figs. 8A and 8B with the handling device 100 according to Fig. 7 in a side view.

[0138] First, the precast concrete element 200 (for example, after demolding at the place of manufacture and / or before installation at the place of installation) can be gripped by moving the handling device 100 towards the precast concrete element 200 until the clamping sections and corresponding clamping jaw sections are aligned; see, for example, Fig. 11 (i) and (ii) as well as Fig. 12 (i) and (ii).

[0139] Then the clamping jaw sections 130 and, if necessary, the clamping jaw sections can be moved towards each other until the corresponding clamping jaw sections and clamping sections are engaged in a force-fit and / or at least partially form-fit manner, and the concrete body is held clamped and can then be lifted; see, for example, Fig. 11 (iii) to (v) and Fig. 12 (iii). The precast concrete element L 200 can then optionally be pivoted by swiveling the swivel sections 140 of the handling device 100, for example, to be placed in the installation position; see, for example, Fig. 11 (iv) and Fig. 12 (iv) to (vi).

[0140] In the above descriptions, the clamping jaw sections 151A to 152B are, by way of example, not movable and are held on the respective pivot section 140, so that a gripping movement to grip or clamp the concrete body is achieved, by way of example, only by moving the jaw sections 130.

[0141] Further embodiments are described below, in which, for example, one or more clamping jaw sections are movable. Particular reference is made to differences compared to previous embodiments.

[0142] Fig. 13A shows an exemplary schematic front view of a handling device 100 for lifting and / or turning concrete bodies according to a further embodiment. Fig. 13B shows another exemplary schematic side view of the handling device 100 according to Fig. 13A. Fig. 13C shows another exemplary schematic front view of the handling device 100 according to Fig. 13A.

[0143] The handling device 100 according to Figs. 13A to 13C is designed according to Fig. 7, wherein optionally the clamping jaw sections 151A and 151B are additionally movable relative to the respective pivot sections 140A and 14B in the X-direction. This allows, for example, a different clamping distance of the respective pairs of clamping jaws, by allowing the clamping jaw sections of a pair of clamping jaws to be moved towards each other and / or away from each other (in particular parallel to the axis A of the pivot sections 140); see, for example, Fig. 13C.

[0144] This has the advantage that longitudinally tapered or curved outer shapes are also possible while saving concrete material, by having corresponding clamping section pairs have different distances between them; see, for example, the longitudinally tapered concrete pipe 300 according to Fig. 14, in which the upper clamping section pair has a smaller distance between them than the lower clamping section pair.

[0145] In some embodiments, the clamping jaw sections 151A and 151B can be moved synchronously (in opposite directions), and in other embodiments, it may be preferred that the clamping jaw sections 151A and 151B can be moved independently of each other. This applies analogously to embodiments described later.

[0146] Fig. 14 shows an exemplary sequence of possible handling procedures for an exemplary, longitudinally tapered, tubular precast concrete element 300 using the handling device 100 according to Figs. 13A to 13C. The process essentially corresponds to that shown in Figs. 11 and 12. Besides simple shapes, such as concrete pipes or even longitudinally tapered precast concrete elements, other precast concrete elements with more complex external shapes can also be handled analogously, for example, oval cone precast concrete elements or slope outlet precast concrete elements 400, as shown, for example, in Fig. 15.

[0147] Fig. 15 shows an exemplary schematic perspective view of another exemplary, longitudinally tapered precast concrete element 400, designed as an example as a slope outlet precast concrete element 400.

[0148] Fig. 16 shows an exemplary illustration of a possible handling of the precast concrete element 400 according to Fig. 15 with the handling device 100 according to Figs. 13A to 13C. Fig. 17 shows an exemplary sequence of a possible handling of the exemplary precast concrete element 400 according to Fig. 15 with the handling device 100 according to Figs. 13A to 13C in a side view. This is analogous to Figs. 11, 12 and 14.

[0149] Fig. 18A shows an exemplary schematic front view of a handling device 100 for lifting and / or turning concrete bodies according to one embodiment. Fig. 18B shows another exemplary schematic side view of the handling device 100 according to Fig. 18A, and Fig. 18C shows another exemplary schematic front view of the handling device 100 according to Fig. 18A.

[0150] The handling device 100 according to Figs. 18A to 18C is designed according to Figs. 7 and 13A, wherein optionally the clamping jaw sections 151A to 152B are also movable relative to the respective pivot sections 140A and 14B in the X-direction, i.e., preferably parallel to the axis A, towards each other and / or away from each other. This allows, for example, a different clamping distance of the respective pairs of clamping jaws analogous to Fig. 13C.

[0151] This has the advantage that even longitudinally tapered or curved outer shapes are possible while saving concrete material, by having corresponding clamping section pairs with different distances between them.

[0152] Furthermore, embodiments can be provided in which the clamping jaw sections of the respective pairs of clamping jaws can be moved independently of each other, so that free-form asymmetrical concrete bodies can also be gripped advantageously; for example, the precast concrete element 600 in Fig. 19.

[0153] Fig. 19 shows an exemplary sequence of possible handling of an exemplary, asymmetrically tubular precast concrete element 600 with the handling device 100 according to Figs. 18A to 18C. Fig. 20 shows an exemplary schematic front view of a handling device 100 for lifting and / or turning concrete bodies according to an embodiment.

[0154] The handling device 100 according to Fig. 20 is designed by way of example such that three pairs of clamping jaws are provided, wherein the clamping jaw sections 150A and 150B of the middle pair of clamping jaws (analogous to Fig. 1A) are held on the pivot sections 130A and 130B in the axis A. By way of example, the two other pairs of clamping jaws with corresponding clamping jaw sections 151A to 152B are arranged next to the axis A analogously to the other preceding examples according to Figs. 7, 13A to 13C, 16 and 18A to 18C, in particular held on the pivot sections 130A and 130B. Preferably, some or preferably all clamping jaw sections can be moved in the direction of the axis A (X-direction), e.g. analogous to Figs. 7, 13A to 13C, 16, 18A to 18C.

[0155] An exemplary handling device 100 according to Fig. 20 has the advantage that precast concrete elements according to Figs. 8A and 8B can be lifted and / or pivoted with the clamping jaw sections 151A to 152B, and analogously, by way of example, also those of Figs. 14, 15, 16, 17 and 19, wherein, in addition, precast concrete elements according to Figs. 2A and 2B can be lifted and / or pivoted with the clamping jaw sections 150A and 150B.

[0156] In the preceding embodiments, the handling device and the precast concrete elements are provided with respective form-fitting clamping sections and clamping jaw sections, in particular such that the clamping hold of the precast concrete element does not only have to be exerted by means of force-fit, but at least a form-fit connection component is added by means of at least a partially form-fit (releasable) connection of the form sections F to the clamping jaw sections and the corresponding form sections N to the clamping sections on the concrete body 210 of the precast concrete element 200, so that the precast concrete element can be clamped at least partially by form-fit, e.g., by form-fit or by force-fit and form-fit. This can reduce the loads occurring during lifting and swiveling.

[0157] The following are a few examples of such exemplary detachable form-fit connections, which should not be understood as restrictive.

[0158] Fig. 21 shows an exemplary schematic sectional view through an exemplary positive locking connection of an exemplary clamping jaw section 150 on the corresponding clamping section 221 of a concrete body 210 of a precast concrete element according to exemplary embodiments.

[0159] Analogous to the above descriptions, the clamping section 221 has, by way of example, a mechanically female forming section N, which can be brought into positive engagement with the, by way of example, mechanically male forming section F of the clamping jaw section 150. By way of example only, the mechanically male forming section F of the clamping jaw section 150 is designed to taper outwards and / or the mechanically female forming section N of the clamping section 221 is designed to taper inwards, so that the engagement of the positive locking connection can be carried out more easily.

[0160] In further embodiments, several matching shaped sections can also be formed on clamping section 221 and clamping jaw section 150. Furthermore, it is possible to adapt several clamping jaw sections arranged side by side to a single clamping section on the concrete body, or to adapt a single clamping jaw section to several clamping sections arranged side by side.

[0161] Fig. 22 shows an exemplary schematic sectional view through another exemplary positive locking connection of an exemplary clamping jaw section 150 on the corresponding clamping section 221 of a concrete body 210 of a precast concrete element according to exemplary embodiments.

[0162] For example, the clamping section 221 has a mechanically male forming section N which can be brought into positive engagement with the mechanically female forming section F of the clamping jaw section 150.

[0163] By way of example only, the mechanically female forming section F of the clamping jaw section 150 is designed to taper inwards and / or the mechanically male forming section N of the clamping section 221 is designed to taper outwards, so that the engagement of the positive locking connection can be carried out more easily.

[0164] In further embodiments, several matching shaped sections can also be formed on clamping section 221 and clamping jaw section 150. Furthermore, it is possible to adapt several clamping jaw sections arranged side by side to a single clamping section on the concrete body, or to adapt a single clamping jaw section to several clamping sections arranged side by side.

[0165] Fig. 23 shows an exemplary schematic sectional view through another exemplary positive locking connection of an exemplary clamping jaw section 150 on the corresponding clamping section 221 of a concrete body 210 of a precast concrete element according to exemplary embodiments.

[0166] As an example, the clamping section 221 on the concrete body is designed as a mechanically male form section N, which is positively engaged by the mechanically female form section F of the exemplary clamping jaw section 150.

[0167] By way of example only, the mechanically female forming section F of the clamping jaw section 150 is designed to taper inwards and / or the mechanically male forming section N of the clamping section 221 is designed to taper outwards, so that engaging the positive locking connection is easier. Fig. 24 shows an exemplary schematic sectional view through another exemplary positive locking connection of an exemplary clamping jaw section 150 on the corresponding clamping section 221 of a concrete body 210 of a precast concrete element according to exemplary embodiments. By way of example, the clamping section 221 on the concrete body is designed as a mechanically female forming section N, with which the mechanically male forming section F of the exemplary clamping jaw section 150 can be positively engaged.

[0168] By way of example only, the mechanically male forming section F of the clamping jaw section 150 is designed to taper outwards and / or the mechanically female forming section N of the clamping section 221 is designed to taper inwards, so that the engagement of the positive locking connection can be carried out more easily.

[0169] Consequently, the present invention, particularly according to the above embodiments, makes it possible to provide simple, efficient and reliable technical solutions for handling precast concrete elements of various sizes and / or shapes, with which the precast concrete elements can be lifted, set down and pivoted simply, efficiently and reliably, in particular from a standing position to a lying installation position.

[0170] It should be noted that only examples and embodiments of the present disclosure, as well as technical advantages, have been described in detail above with reference to the accompanying figures. However, the present disclosure is in no way limited or restricted to the embodiments and their features or combinations described above, but also includes modifications of these embodiments, in particular those resulting from modifications of the features of the described examples or from combinations or partial combinations of one or more of the features of the described examples within the scope of protection of the independent claims.
