Description

[0001] The invention relates to a bending device for automatically bending at least one air conditioning pipe, in particular a heating and / or cooling pipe, according to the preamble of claim 1. Furthermore, the invention relates to a device for manufacturing a reinforcement device with a bending device according to claim 9 and a device for manufacturing a concrete part with at least one air conditioning pipe integrated in the concrete part according to claim 10. The invention also relates to a method for automatically bending at least one air conditioning pipe according to claim 12, a method for manufacturing at least one reinforcement device according to claim 14, and a method for manufacturing a concrete part with an air conditioning pipe integrated in the concrete part according to claim 15.

[0002] Temperable concrete elements can be used to create temperature-controlled walls, floors, and / or ceilings in buildings. These elements incorporate a climate control pipe, and the flow of a cold or hot liquid, such as water, cools or heats the concrete. To ensure the most even temperature distribution across the concrete, the climate control pipes are often designed with numerous bends. For example, they can be laid in a meandering or double meandering pattern.

[0003] In the production of temperature-controlled concrete parts, an air conditioning pipe shaped in the desired form is placed in the concrete mold before the concrete is poured and then covered with concrete.

[0004] The concrete components often also contain a reinforcement device. The air conditioning pipe can be attached to the reinforcement device before the concrete is poured. For example, the attachment of a pre-formed air conditioning pipe to a reinforcement device is disclosed in German patent application DE 10 2004 034 707 A1.

[0005] A known method for manufacturing an air conditioning duct involves manually bending the duct. The duct can be pre-shaped manually or attached to a reinforcement jig during the bending process. A disadvantage of manual bending is the high cost, as it requires considerable time and labor.

[0006] Methods for automatically bending an air conditioning pipe using pipe bending machines are also known from the prior art. In particular, freeform bending allows for the creation of virtually any shape, especially shapes previously designed on a computer. Prior art pipe bending machines typically have a stationary bending head for bending the pipe and a feed device for moving the pipe, which inevitably causes the already formed part of the pipe to move and / or twist during the bending process. A disadvantage of automatic bending with known pipe bending machines is that an air conditioning pipe cannot be directly attached to a reinforcement device and / or fastening device.

[0007] Based on this prior art, it is an object of the following invention to provide a bending device and a method for automatically bending at least one air conditioning pipe, a device and a method for manufacturing a reinforcement device with an air conditioning device, and a device and a method for manufacturing a concrete part with at least one air conditioning pipe integrated in the concrete part, which at least partially eliminate or reduce the disadvantages described above.

[0008] In particular, a bending device is to be created which enables the automated and therefore more cost-effective production of a concrete part with an integrated air conditioning pipe.

[0009] A bending device according to the invention for automatically bending at least one air conditioning pipe, in particular at least one heating and / or cooling pipe, comprises a bending head, wherein the bending head comprises a bending unit for bending and a support unit for supporting the at least one air conditioning pipe.

[0010] According to the invention, the bending device has a movement system wherein the at least one bending head can be moved by the movement system at least in one plane of movement in two spatial directions.

[0011] Because the bending head is movable by the movement system, the already formed part of the air conditioning pipe does not have to move or twist during bending. In particular, the already formed part of the air conditioning pipe can be positioned on a stationary fastening device, especially a reinforcement device, during the bending process.

[0012] The term "pre-formed part of the (at least one) air conditioning pipe" refers to the part of the at least one air conditioning pipe that has already been shaped as desired by the bending unit. In particular, this part can be bent or straight in sections.

[0013] The fastening device can be transported directly to the concrete mold for pouring. This simplifies the automation of the entire manufacturing process, among other things because separate gripping and positioning of the air conditioning pipe becomes obsolete.

[0014] In one embodiment of the bending device, the bending unit comprises at least one feed device with which the at least one air conditioning pipe can be displaced relative to the at least one bending head. This allows the at least one air conditioning pipe to be actively moved away from the bending head.

[0015] The sliding movement can be coordinated with the movement of the bending head, preferably in such a way that the already formed part of the air conditioning pipe is not moved.

[0016] The bending unit may be provided with at least two guide rollers, preferably with the at least one air conditioning pipe being clampable between at least two guide rollers. This ensures that the at least one air conditioning pipe is held in place by the guide rollers.

[0017] It can be provided that the at least two guide rollers are designed as a feed device, wherein the at least one air conditioning pipe can be displaced relative to the bending head by a rotation of the at least two guide rollers. This allows the at least one air conditioning pipe to be moved relative to the bending head in a simple manner.

[0018] In one embodiment, at least one, preferably both, of the at least two guide rollers is designed as a roller with a groove on its running surface, wherein the at least one air conditioning tube can be arranged in the groove. This holds the at least one air conditioning tube between the guide rollers.

[0019] In a preferred embodiment, the axes of rotation of the at least two guide rollers are arranged essentially orthogonally to the plane of motion. Thus, the guide rollers themselves are arranged essentially parallel to the plane of motion.

[0020] It can be provided that the at least two guide rollers are rotatably mounted on a support, wherein the support is arranged on the bending unit and / or rotatably mounted relative to the bending unit and / or one axis of rotation of the support is perpendicular to the plane of movement. By rotating the support, the guide rollers can be rotated together. This allows the at least one air conditioning pipe, which is clamped between the guide rollers, to be bent.

[0021] The at least two guide rollers can each be rotatably mounted about a first axis of rotation and can be jointly rotatably mounted about a second axis of rotation. This allows, on the one hand, the rotation of the at least two guide rollers themselves about their first axes of rotation, preferably for moving the air conditioning pipe relative to the bending head. On the other hand, rotation about a common second axis of rotation allows both guide rollers to be twisted, thereby shaping, in particular bending, the at least one air conditioning pipe as desired.

[0022] The position of the support unit can be adjusted relative to the bending unit in a direction essentially orthogonal to the plane of movement. This allows parts of the support unit to be moved into or out of the plane of movement, so that the support unit can support the already formed part of the at least one air conditioning pipe located in the plane of movement, or be guided past the already formed part of the at least one air conditioning pipe located in the plane of movement.

[0023] The position of the support unit relative to the bending unit in the plane of motion can be adjusted. This allows the already formed part of the at least one air conditioning pipe to be supported by the support unit while the bending unit continues to move and further shape the air conditioning pipe.

[0024] The support unit can have at least one support element, preferably comprising at least one support roller. This allows the support element to roll along the air conditioning pipe.

[0025] At least one of the support elements can be designed to pivot. This allows the support element to be positioned against the air conditioning pipe by pivoting it.

[0026] At least two support elements can be provided on the support unit.

[0027] In one embodiment, the bending device has at least one coil holder for receiving a coil with at least one air conditioning tube wound on it, preferably wherein the at least one coil holder is movable together with the bending head. This allows the air conditioning tube to be positioned at any point on the bending head. The movement of the coil holder can also be limited to one direction within the plane of motion.

[0028] At least two coil holders can be provided. This allows an air conditioning duct to be stored in advance and the coils to be changed quickly.

[0029] The bending device can include a straightening unit, preferably wherein the at least one straightening unit is movable together with the bending head. The at least one straightening unit can have an opening for the passage of the at least one air conditioning pipe. This allows the air conditioning pipe to be supplied to the bending head in a controlled manner. In particular, this prevents the need for frequent connection of the air conditioning pipe to a reinforcement device and / or fastening device.

[0030] It can be provided that the at least one straightening unit is arranged between the at least one coil holder and the at least one bending head, preferably wherein the at least one air conditioning pipe can be guided from the coil on the at least one coil holder via the at least one straightening unit to the at least one bending head. It can also be provided that the straightening unit is rigidly connected to a coil holder.

[0031] The motion system can comprise at least two rails, preferably wherein at least two rails are arranged at right angles to each other and / or the bending head is movably arranged on at least one rail, and / or at least a second rail is movably arranged on at least a first rail. By using two rails, the bending head can be moved in a plane of motion.

[0032] At least three rails can be provided, with at least two first rails being parallel to each other, with at least one second rail being movably arranged on the at least two first rails, with the at least two first rails and the at least one second rail being at right angles to each other, and with the at least one bending head being movably arranged on the at least one second rail. Thus, the at least one second rail is stably supported on the at least two first rails.

[0033] In one embodiment, the bending device has at least one fastening device, preferably in the form of a beam, preferably at least two parallel beams, and / or in the form of a reinforcing steel mesh, and / or in the form of a steel wire structure. The at least one air conditioning pipe can be attached to the at least one fastening device during the bending process.

[0034] At least one of the fastening devices can be suitable as a reinforcement device for a concrete component. In this case, the reinforcement device and the air conditioning pipe attached to it can be cast together in concrete.

[0035] The at least one fastening device can have at least one bracket for attaching the at least one air conditioning pipe to the at least one fastening device, preferably wherein the at least one bracket has at least one spring clamp and / or locking device. This allows the at least one air conditioning pipe to be attached to the at least one bracket by means of at least one spring clamp and / or locking device. This represents a simple way of attaching the air conditioning pipe to the fastening device.

[0036] The at least one bracket can be attached to the mounting device by at least one spring clamp and / or locking device. Therefore, for example, two spring clamps and / or locking devices can be provided: one for attaching the air conditioning pipe to the bracket and a second for attaching the bracket to the mounting device.

[0037] The at least one bracket can have a base surface, wherein the at least one fastening device, in particular a reinforcement device, can be supported on a pallet by means of this base surface. Particularly preferably, the at least one bracket has a base surface in a first end region, can be fastened to the at least one fastening device in a second end region, and can be fastened to the at least one air conditioning pipe in a region between the first and second end regions. During concrete casting, the pallet, together with formwork elements, can form a concrete mold. The air conditioning pipe and the fastening device can be positioned at a distance from each other and from the pallet by means of a bracket shaped as described. This allows the positioning of the air conditioning pipe and the fastening device within the concrete element to be controlled, preferably centrally.

[0038] It may be provided that the bending head has at least one punch, wherein the at least one air conditioning pipe can be pressed into the at least one holder with the at least one punch.

[0039] This allows at least one air conditioning pipe to be pressed into at least one holder during the bending process. In particular, this eliminates the need for a separate fastening step and a separate removal of the already formed air conditioning pipe during the production process.

[0040] In one embodiment, the bending device has a control unit, preferably wherein the bending device can be controlled by the control unit using CAD data. This allows the desired shape of the air conditioning pipe to be planned in advance on a computer and then automatically implemented.

[0043] In one embodiment of the method for automatically bending at least one air conditioning pipe, the following process step is provided: The displacement of the at least one air conditioning pipe by means of the at least one feed direction relative to the at least one bending head is coordinated with the movement of the at least one bending head, preferably in such a way that the at least one air conditioning pipe is not moved before and / or after the at least one bending head relative to the bending device.

[0044] In a further embodiment of the method for automatically bending at least one air conditioning pipe, at least one of the following process steps is provided: The at least one air conditioning pipe is clamped between two guide rollers, a support element is pivoted into the support position, and the at least one air conditioning pipe is supported by a first support element. The at least one bending head is moved along the air conditioning pipe to the pre-programmed start of the bend.

[0045] The following procedural step is provided in addition or as an alternative: The at least one bending head moves through the motion system along a pre-programmed curved path, preferably within the plane of motion and particularly preferably along a circular path within the plane of motion, wherein the two guide rollers together with a support perform a rotational movement about an axis of rotation of the support, preferably wherein the rotational movement is performed such that an imaginary connecting plane between the two axes of rotation of the guide rollers is orthogonal to the tangent of the bent air conditioning pipe.

[0046] The following procedural step is provided in addition or as an alternative: The distance between the bending unit and the support unit is continuously varied so that the first support element rests against at least one air conditioning pipe for at least part of the bending process.

[0047] Additionally or alternatively, at least one of the following procedural steps is provided: The at least one bending head moves along a pre-programmed first curved path within the plane of motion, preferably along a circular path within the plane of motion, wherein the direction at the beginning of the first curved path differs substantially by 180 degrees from the direction at the end of the first curved path; the distance between the bending unit and the support unit is varied during the traversal of the first curved path such that a first support element bears against the air conditioning pipe at least during part of the bending process; the bending head moves substantially along a straight line to the pre-programmed beginning of a second curved path; the first support element is pivoted into a waiting position; and the support unit is displaced relative to the bending unit so that the support elements are no longer arranged in the plane of motion; the distance between the bending unit and the support unit is changed.The support unit is moved relative to the bending unit so that the support elements are arranged in the plane of motion, and the second support element is pivoted into the support position so that the second support element rests against the air conditioning pipe in the support position. The at least one bending head moves along a pre-programmed second curved path within the plane of motion, preferably wherein the sign of the overall curvature of the second curved path is different from the sign of the overall curvature of the first curved path.

[0048] A device according to the invention for manufacturing a reinforcement device with at least one air conditioning pipe comprises a bending device as described above. This allows the at least one air conditioning pipe to be attached to the reinforcement device by means of the bending device.

[0049] In a preferred embodiment, the at least one air conditioning pipe can be attached to the reinforcement device by means of a holder, preferably wherein the at least one holder has at least one spring clamp and / or locking device, and / or by means of wire.

[0050] The combination of reinforcement device and air conditioning pipe can be stored together and / or used to manufacture a concrete part.

[0051] A method according to the invention for producing at least one reinforcement device for a concrete part using a device for producing a reinforcement device described above, wherein the air conditioning pipe is bent using a method described above, is characterized by the following method steps: The at least one air conditioning pipe is attached to the reinforcement device by means of at least one bracket, preferably wherein the at least one bracket has at least one spring clamp and / or locking device, and / or by means of wire.

[0052] A device according to the invention for producing a concrete part with at least one air conditioning pipe integrated in the concrete part comprises a bending device as described above.

[0053] The device for producing a concrete part can comprise a pallet equipped with formwork elements and at least one fastening device, wherein the at least one air conditioning pipe can be attached to the at least one fastening device by means of the bending device, and wherein the device for producing a concrete part comprises a transfer device for moving the at least one fastening device. Because the at least one air conditioning pipe can be attached to the fastening device, transport by the transfer device is simplified. In particular, the at least one air conditioning pipe does not need to be handled separately.

[0054] In a first embodiment, the at least one fastening device can be transported onto the pallet by means of the transfer device, preferably wherein the at least one fastening device is designed as a reinforcement device for the concrete part and / or the fastening device has at least one bracket, wherein the at least one bracket allows the at least one fastening device to be positioned at a distance from the bottom of the pallet and / or the at least one air conditioning pipe to be positioned at a distance from the at least one fastening device. This allows the positioning of the air conditioning pipe and the reinforcement device within the concrete part to be controlled.

[0055] In a second embodiment, the at least one fastening device can be transported across the pallet by means of the transfer device, wherein the at least one air conditioning pipe can be detached from the at least one fastening device by means of a release bar and placed on the pallet and / or on a reinforcement device resting on the pallet. This allows the air conditioning pipe to be integrated into a concrete element independently of any reinforcement device.

[0056] A method according to the invention for producing a concrete part with at least one air conditioning pipe integrated in the concrete part by means of a device for producing a concrete part described above, wherein the air conditioning pipe is bent by means of a method described above, is characterized by the following method steps: The at least one air conditioning pipe is attached to at least one fastening device, and the at least one fastening device with the at least one air conditioning pipe is transported by a transfer device from the bending device to a pallet equipped with formwork elements.

[0057] In a first embodiment of a method for producing a concrete part with at least one air conditioning pipe integrated into the concrete part, the following process step is included: The at least one fastening device with the at least one air conditioning pipe is transported onto the pallet, preferably wherein the fastening device is designed as a reinforcement device of the concrete part and / or the at least one fastening device has at least one support, wherein the at least one support arranges the at least one fastening device on the pallet at a distance from the ground and / or the at least one air conditioning pipe is arranged at a distance from the at least one fastening device.

[0060] At least one air conditioning pipe can be designed to be dimensionally stable.

[0061] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings. These show: Fig. 1 Device for producing a concrete part with an air conditioning pipe, Fig. 2 as Fig. 1 In an alternative view, Fig. 3 shows an alternative embodiment of a device for producing a concrete part with an air conditioning pipe, Fig. 4 shows a bending device for bending an air conditioning pipe, Fig. 5 shows a bending device with a fastening device, Fig. 6 shows a reinforcing steel mesh with brackets for fastening an air conditioning pipe, Figs. 7a-7c show a bracket for fastening an air conditioning pipe, Figs. 8a-8e show a bending head in various process steps of bending an air conditioning pipe, and Fig. 9 shows a section through a concrete part with a reinforcement device and an air conditioning pipe.

[0062] The Fig. 1 and 2Figure 2 shows a device 2 for manufacturing a concrete part 45 with an integrated air conditioning pipe 4. The device 2 includes a bending device 1 for bending the air conditioning pipe 4. Furthermore, a device 2 for manufacturing a reinforcement device 46 with an air conditioning pipe 4 and a device 40 for manufacturing a reinforcement device 46 (without an air conditioning pipe) are shown in the two figures. The process described below can be fully automated, with operation via a control unit 42. The reinforcement device 46 itself is shown in the Figuren 1 and 2 only schematically indicated.

[0063] First, a reinforcement device 46 (without air conditioning pipe 4) is automatically assembled and welded together using the device 40 for the production of a reinforcement device 46 (without air conditioning pipe 4). The steel wire 43 used for this purpose is stored on a spool holder 41 for steel wire. The reinforcement device 46 produced in this way is transported to the area of ​​the bending device 1.

[0064] The bending device 1 for automatically bending at least one air conditioning pipe 4 comprises a bending head 6 and a movement system 5, wherein the bending head 6 is movable in a plane of movement in two spatial directions by the movement system 5.

[0065] The bending device 1 has a coil holder 9 for receiving a coil 18 with at least one air conditioning tube 4 wound on it.

[0066] The motion system 5 comprises three rails 20, with two first rails 21 being parallel to each other. A second rail 22 is movably arranged on the two first rails 21, the two first rails 21 and the second rail 22 being at right angles to each other, and the bending head 6 being movably arranged on the second rail 22.

[0067] In the Fig. 1 and 2 The first two rails 21 are arranged vertically and the second rail 22 is arranged horizontally. This allows the bending head 6 to be moved in a vertically oriented plane of movement.

[0068] The air conditioning pipe 4 can be attached to a mounting device 11 arranged parallel to the plane of movement. In the Fig. 1 and 2 The air conditioning pipe 4 has already been bent into a meandering shape. This ensures that the air conditioning pipe 4 fills as much of the surface as possible.

[0069] The shaped air conditioning pipe 4 can be attached to the reinforcement device 46, preferably wherein the fastening device 11 is tilted into a horizontal plane and then attached to the reinforcement device 46.

[0070] Using a transfer device 31, the reinforcement device 46 with the air conditioning pipe 4 is transported onto a pallet 10. There, the reinforcement device 46 and the air conditioning pipe 4 are encased in concrete.

[0071] It may be provided that the reinforcement device 46 has at least one support 26 for holding the air conditioning pipe 4, wherein the at least one support 26 arranges the at least one reinforcement device 46 at a distance from the ground on the pallet 10 and / or arranges the at least one air conditioning pipe 4 at a distance from the at least one fastening device 11.

[0072] Alternatively, the fastening device 11 itself can be transported over the pallet 10 by means of the transfer device 31, wherein the at least one air conditioning pipe 4 is preferably separated from the at least one fastening device 11 by means of a pressure-off bar. The separation of the air conditioning pipe 4 from the fastening device 11 can also be achieved by pulling on the supports. The air conditioning pipe 4 is placed on the pallet 10 and / or on a reinforcement device 46 resting on the pallet 10.

[0073] In another embodiment, the reinforcement device 46 can function as a fastening device 11. In this embodiment, the air conditioning pipe 4 can be attached directly to the fastening device 11 / reinforcement device 46 during the bending process. Preferably, the fastening device 11 / reinforcement device 46 has at least one holder 26 into which the at least one air conditioning pipe 4 can be fastened during the bending process.

[0074] By preferably attaching the at least one air conditioning pipe 4 to at least one support 26 on the fastening device 11 (optionally designed as a reinforcement device 46) during the bending process, the shaped air conditioning pipe 4 does not need to be attached in an additional step.

[0075] The Fig. 3 Figure 1 shows an alternative embodiment of a device 2 for producing a concrete part 45 with an air conditioning pipe 4 integrated in the concrete part 45 with a bending device 1.

[0076] In this embodiment, the fastening device 11 is arranged horizontally. This allows an air conditioning pipe 4 attached to it to be transported over a pallet 10 using the transfer device 31 without tilting the fastening device 11.

[0077] The motion system 5 allows the bending head 6 to be moved in a plane of motion, which is arranged horizontally here. The motion system 5 consists, as in the Fig. 1 and 2 The device consists of three rails 20, all of which are arranged horizontally. The first two rails 21 are arranged parallel to each other. A second rail 22 is movably mounted on these, and the bending head 6 is movably mounted on this second rail 22.

[0078] In this embodiment, the coil holder 9 is moved together with the bending head 6. To load the coil holder 9 with a coil 18, the coil holder 9 and the bending head 6 move into a designated loading position.

[0079] The Fig. 4 Figure 1 shows a bending device 1 with a bending head 6 arranged on a motion system 5. The motion system 5 consists, as shown in the figure 1, of a bending device 1 with a bending head 6 arranged on a motion system 5. The motion system 5 consists of a bending device 1 with a bending head 6 arranged on a motion system 5. The figure 1 ... Fig. 3 from three rails 20, whereby in the Fig. 4 Only two rails, 21 and 22, are visible.

[0080] Just like in the Fig. 3 The coil holder 9, with the air conditioning pipe 4 wound onto it as a coil 18, is moved together with the bending head 6. In the Fig. 4 A total of three coil holders 9 are provided. This allows the coils 18 to be changed quickly.

[0081] The bending device 1 has one straightening unit 14 per coil holder 9. Like the coil holders 9, the straightening units 14 are also movable together with the bending head 6. Each straightening unit 14 has an opening 19 for the passage of the air conditioning pipe 4.

[0082] The straightening unit 14 is arranged between the coil holder 9 and the bending head 6. The air conditioning tube 4 from the coil 18 on the coil holder 9 is guided to the bending head 6 via the at least one straightening unit 14, in particular through an opening 19. This allows the direction of the air conditioning tube 4's feed to the bending head 6 to be controlled; in particular, this reduces the frequency with which the air conditioning tube 4 needs to be connected to and / or held by a reinforcement device 46.

[0083] The bending head 6 comprises a bending unit 7 for bending and a support unit 8 for supporting the air conditioning pipe 4. The position of the support unit 8 relative to the bending unit 7 is adjustable in a direction substantially orthogonal to the plane of movement and / or in the plane of movement.

[0084] The bending unit 7 has two guide rollers 13, wherein the air conditioning tube 4 can be clamped between the two guide rollers 13. The two guide rollers 13 also serve as a feed device 12, wherein the air conditioning tube 4 can be displaced relative to the bending head 6 by a rotation of the at least two guide rollers 13.

[0085] Two support elements 16 are arranged on the support unit, wherein the two support elements 16 each comprise a support roller 17.

[0086] The air conditioning pipe 4 is bent by rotating the two guide rollers 13 while simultaneously supporting the air conditioning pipe 4 against at least one support element 16.

[0087] The Fig. 5 Figure 1 shows a bending device 1 with a fastening device 11 arranged horizontally above the bending head 1. The air conditioning pipe 4 is already fully attached to the fastening device 11 in a meandering shape.

[0088] For this purpose, the bending head 6 had to travel the entire length of the already formed air conditioning pipe 4, which is made possible by the movement system 5. In the curves, the bending head 5 must bend the air conditioning pipe 4 using the guide rollers 13 and the support rollers 17. A detailed description of the bending process is provided in the Fig. 8a bis 8e shown.

[0089] The fastening device 11 has several parallel beams 23. The beams 23 have several brackets 26 for fastening the air conditioning pipe 4. The brackets 26 are preferably designed as spring clamps 27 and / or spring-loaded clamps, so that the air conditioning pipe 4 only needs to be pressed into the brackets 26. This pressing action can be achieved, for example, by means of a punch (not shown) on the bending head 6.

[0090] Such a fastening device 11 can be transported via a pallet 10 by means of a transfer device 31, wherein the air conditioning pipe 4 can be separated from the at least one fastening device 11 by means of a push-off bar and placed on the pallet 10 and / or on a reinforcement device 46 resting on the pallet 10.

[0091] The Fig. 6 Figure 1 shows a reinforcing steel mesh 24 with brackets 26 for attaching an air conditioning pipe 4. The reinforcing steel mesh 24 can be used as a fastening device 11; in particular, the air conditioning pipe 4 can be automatically attached to the reinforcing steel mesh 24 during the bending process using the bending device 1. This eliminates the need for manual attachment of the air conditioning pipe 4 to the reinforcing steel mesh 24.

[0092] The supports 26 have a bearing surface 29 by means of which the air conditioning pipe 4, together with the reinforcing steel mesh 24, can be supported on the base of a pallet 10. This allows the reinforcing steel mesh 24 and the air conditioning pipe 4 to be positioned at a distance from the base of the pallet 10. Furthermore, the air conditioning pipe 4 is positioned at a distance from the reinforcing steel mesh 24. This allows the air conditioning pipe 4 and the reinforcing steel mesh 24 to be positioned close to the core of the concrete element 45. This also ensures that the air conditioning pipe 4 and the reinforcing steel mesh 24 do not protrude from the concrete element 45.

[0093] If the components are arranged on the bottom of a pallet 10, they have the following order: at the bottom the base 29 for placement on the bottom of the pallet 20, in the middle the air conditioning pipe 4, at the top the reinforcing steel mesh 24. The components are spaced apart from each other.

[0094] The Fig. 7a bis 7c show different views of a bracket 26, in particular those from Fig. 6 . The Fig. 7a und 7b This shows side views and the Fig. 7c a perspective view.

[0095] The bracket 26 has a contact surface 29 in a first end region. The contact surface 29 preferably consists of several, in particular six, contact points.

[0096] In a second end area, the bracket 26 can be attached to a reinforcement device 46, and in an area between the first and the second end area, the air conditioning pipe 4 can be attached.

[0097] The bracket 26 has two locking devices 28. A first locking device 28 is arranged at the opposite end of the bearing surfaces 29. A reinforcement device 46, preferably a reinforcing steel mesh 24, can be attached to the bracket 26 by means of the first locking device 28. A second locking device 28 is accessible from the side of the bearing surfaces 29. An air conditioning pipe 4 can be attached to the bracket 26 by means of the second locking device 28.

[0098] The holders 26 are designed as clips. In particular, the locking devices 28 have several teeth in the form of barbs. This holds a reinforcement device 46 and / or an air conditioning pipe 4 in the holders 26, whereby a reinforcement device 46 and / or an air conditioning pipe 4 only needs to be pressed into the clip.

[0099] The brackets 26 can release an air conditioning pipe 4 by pulling on them. This spreads the second locking device 28, thereby releasing the air conditioning pipe 4.

[0100] The bracket 26 is preferably made of plastic.

[0101] As an alternative to a bracket 26, the air conditioning pipe 4 can be attached to the reinforcement device 46 using wire.

[0102] The Fig. 8a bis 8e Figure 1 shows several process steps of an embodiment of the method for automatically bending an air conditioning pipe 4 using the bending device 1.

[0103] The air conditioning pipe 4 is in Fig. 8a The air conditioning pipe 4 is already clamped between two guide rollers 13 arranged on the bending unit 7. It is held securely there because at least one, preferably both, of the two guide rollers 13 are designed as a roller with a groove 39 on the running surface, and the air conditioning pipe 4 can be arranged in the groove 39.

[0104] The displacement of the at least one air conditioning pipe 4 by means of the two guide rollers 13 relative to the at least one bending head 6 is coordinated with the movement of the at least one bending head 6, preferably in such a way that the at least one air conditioning pipe 4 is not moved before and / or after the at least one bending head 6 relative to the bending device 1 and / or to the fastening device 11.

[0105] A first support element 33 is pivoted into the support position and the air conditioning pipe 4 is supported by a first support element 33,

[0106] The bending head 6 is moved along the air conditioning pipe 4 to the pre-programmed start of the bend.

[0107] The Fig. 8b shows the bending of the air conditioning pipe 4 in a first direction.

[0108] The bending head 6 is shaped as follows: The axes of rotation 35 of the at least two guide rollers 13 are essentially orthogonal to the plane of motion. The two guide rollers 13 are rotatably mounted on a support, the support being in the Fig. 8a bis 8e The beam is concealed by the guide rollers 13. The beam is arranged on the bending unit 7 and / or rotatably mounted relative to the bending unit 7, with a rotation axis 36 of the beam being normal to the plane of movement.

[0109] This means that the two guide rollers 13 are each rotatably mounted about a first axis of rotation 35 and together rotatably mounted about a second axis of rotation 36.

[0110] The bending process is carried out as follows: The bending head 6 moves through the motion system 5 along a pre-programmed curved path, preferably within the plane of motion and particularly preferably along a circular path within the plane of motion. The two guide rollers 13, together with a support, perform a rotational movement about an axis of rotation 36 of the support, preferably such that an imaginary connecting plane 37 between the two axes of rotation 35 of the guide rollers 13 is orthogonal to the tangent 38 of the bent air conditioning pipe 4.

[0111] The distance between the bending unit 7 and the support unit 8 is continuously varied so that the first support element 33 rests against the air conditioning pipe 4 for at least part of the bending process.

[0112] The Fig. 8c Figure 4 shows a fully executed bend along the first curve of the air conditioning pipe 4. The direction at the beginning of the first curve differs essentially by 180 degrees from the direction at the end of the first curve. This is typical for a meander.

[0113] The distance between the bending unit 7 and the support unit 8 was varied during the passage through the first curved track so that the first support element 33 was still in contact with the air conditioning pipe 4.

[0114] The bending head 6 moves essentially along a straight line to the pre-programmed beginning of a second curved path. The bending head 6 can only move far enough away from the first curved path, in particular far enough to allow space for the second support element 34 next to the guide rollers 13.

[0115] In the Fig. 8d The first support element 33 is swung into a waiting position.

[0116] The support unit 8 is moved relative to the bending unit 7 so that the support elements 33, 34 are no longer arranged in the plane of movement.

[0117] It is also possible that the support elements 33, 34 are already in a waiting position and no longer arranged in the plane of movement. In this case, the support unit 8 does not need to be moved relative to the bending unit 7 in a direction orthogonal to the plane of movement and can, in particular, be rigidly connected to the bending unit 7.

[0118] It should be noted here that the movements are orthogonal to the plane of movement in the top view. Fig. 8a bis 8e are not apparent.

[0119] In the Fig. 8e The distance between the bending unit 7 and the support unit 8 is changed.

[0120] The support unit 8 is moved relative to the bending unit 7 so that the support elements 33, 34 are arranged in the plane of movement and the second support element 34 is pivoted into the support position so that the second support element 34 rests against the air conditioning pipe 4 in the support position.

[0121] This establishes the starting position for the bend along a second curved path of the air conditioning pipe.

[0122] The at least one bending head 6 moves along a pre-programmed second curved path within the plane of motion, preferably wherein the sign of the overall curvature of the second curved path differs from the sign of the overall curvature of the first curved path. This creates a second meander.

[0123] By repeatedly performing the described meandering bend, a meander-shaped air conditioning pipe 4 is produced, as is used, for example, in the Fig. 5 is shown.

[0124] The bending device 1 can also be used to create virtually any other shape of the air conditioning pipe 4. The shapes can be provided to the bending device 1, in particular by means of a control unit 42, using CAD data.

[0125] A special feature of the bending device 1 is that the air conditioning pipe 4 can be bent in two different directions without twisting the air conditioning pipe 4.

[0126] The Fig. 9 Figure 45 shows a concrete element 45 with reinforcement device 46 and air conditioning pipe 4. The reinforcement device 46 is designed here as a reinforcing steel mesh 24 with vertical struts. The concrete 44 is shown in cross-section. The air conditioning pipe 4 meanders through the entire concrete element 45, thus enabling heating or cooling of the concrete 44 across its surface. Reference symbol list:
