Description

[0001] The invention relates to a method for producing a three-dimensional reinforcement structure, preferably a reinforcement cage for tunnel segments, and to a system for the fully automatic production of a three-dimensional reinforcement structure, preferably a reinforcement cage for tunnel segments, wherein the system is configured to carry out such a method.

[0002] Complex three-dimensional reinforcement structures are required for the production of precast concrete elements, such as tunnel segments, for the construction of tunnels or wind turbines. Tunnel segments are prefabricated arch segments used for lining shafts and tunnels, providing structural support. High precision is essential for these segments.

[0003] The Figure 1Figure 13 shows an example of such a three-dimensional reinforcement structure in the form of a reinforcement cage, which is assembled and welded together from two rolled reinforcement mats 14, 36 and straight reinforcement ladders 27, 31 and curved reinforcement ladders 15, 26 arranged between them. The reinforcement mats and ladders can be formed from straight and / or curved transverse bars 41 and longitudinal bars 42. In the following, the ladders and mats are collectively referred to as reinforcement mats.

[0004] It is known from the prior art that the reinforcing mats are assembled manually in a template 43, fastened by means of stabilizers 45 and subsequently welded together by means of a welding robot 44 (cf. Fig. 5After the welding process, the stabilizers are removed and the finished reinforcement cage is transported away. Assembling the reinforcement cage and subsequently welding it requires a precise template and manual intervention. Flexible, just-in-time production is not possible.

[0005] JP H06 226387 A discloses a method in which an outer steel reinforcement is preformed into a cage-like structure and then an inner reinforcement is inserted diagonally into the cage-like structure by means of a wire mesh insertion device and welded to it.

[0006] Documents CN 112 008 021 B, DE 10 2013 018907 A1, CN 114 425 672 A and IT 2021 0000 6197 A1 represent a further state of the art. In DE 10 2013 018907 A1, tunnel segments are welded together with U-shaped bent transverse wires using continuously fed and bent longitudinal wires.

[0007] The object of the present invention is to provide a method for manufacturing a three-dimensional reinforcement structure, preferably a reinforcement cage for tunnel segments, which is improved compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated, and which in particular enables flexible and just-in-time production. Furthermore, a system for the fully automated production of a three-dimensional reinforcement structure, preferably a reinforcement cage for tunnel segments, is to be provided, wherein the system is configured to carry out such an improved method. This object is achieved by the features of claims 1 and 12.

[0008] The method for producing a three-dimensional reinforcement structure, preferably a reinforcement cage for tunnel segments, is characterized by the following process steps: a first two-dimensional reinforcement mat is provided and arranged in a first plane that is at least partially curved; at least one second, curved, preferably ladder-shaped, two-dimensional reinforcement mat is provided; the at least one second reinforcement mat is positioned and held in a second plane transverse to the first plane by means of at least one positioning device that can be moved relative to the first plane, such that the two reinforcement mats overlap at intersection points on a curved side edge of the at least one first reinforcement mat; and the two reinforcement mats are joined to each other at least at part of the intersection points by means of at least one welding device.preferably welded by means of at least one welding robot, while the at least one second reinforcement mat is held in the second plane by means of the at least one positioning device, wherein the at least one second reinforcement mat is welded to the at least one first reinforcement mat at the curved side edge of the at least one first reinforcement mat.

[0009] Compared to the state of the art, this method offers the technical advantage that all process steps—the provision, the positioning of the two reinforcement mats relative to each other, and the welding—can be performed automatically, eliminating time-consuming manual interventions that carry the risk of mispositioning. Furthermore, positioning and welding can be carried out simultaneously, without the need for additional stabilization of the reinforcement elements using a template and stabilizers. Virtually any shape, such as reinforcement cages with varying curvatures and dimensions, can be produced without having to change a template between shapes. This means that shape changes can be made without any loss of time, enabling just-in-time production.

[0010] The inventive system for the fully automated production of a three-dimensional reinforcement structure, preferably a reinforcement cage for tunnel segments, is designed to carry out the inventive method, wherein the system comprises at least one or more stations in which the first two-dimensional reinforcement mat can be provided and arranged in the first at least partially curved plane, and in which the at least one second self-curved two-dimensional reinforcement mat can be provided and welded to the at least one first reinforcement mat, wherein at least one positioning device movable relative to the first plane is provided, wherein the positioning device is configured to position and hold the at least one second reinforcement mat in a second plane transverse to the first plane in such a way thatthat the two reinforcement mats overlap at intersection points on a curved side edge of the at least one first reinforcement mat, and at least one welding device, preferably at least one welding robot, is provided, wherein the at least one welding device is configured to weld the at least one second reinforcement mat to the at least one first reinforcement mat at the curved side edge of the at least one first reinforcement mat.

[0011] The invention automates the assembly of a three-dimensional reinforcement structure, performing it just-in-time with the welding of the individual components. For this purpose, the fully automated system comprises one or more stations for feeding, assembling, and / or positioning the individual components with simultaneous welding.

[0014] The Figures 1 to 5 have already been described in the introductory section.

[0015] The Figure 6 Figure 1 shows a preferred embodiment of a system 19 according to the invention for the fully automatic production of a three-dimensional reinforcement structure 13, preferably a reinforcement cage for tunnel segments, wherein the system 19 comprises at least two, preferably more than two, spatially separated stations 20, 21, 33, 34, which are traversed successively in the production direction 35, wherein the system 19 is configured to perform a method 1 (see also the Fig. 14) to produce a three-dimensional reinforcement structure 13, preferably a reinforcement cage for tunnel segments.

[0016] Alternatively, the system 19 can also have only one station in which several process steps, e.g. the first process step 2 and the second process step 3 described below, are carried out.

[0017] Method 1 comprises a first process step 2 in which a first two-dimensional reinforcement mat 14 is provided and arranged in a first plane that is at least partially curved.

[0018] The system 19 includes a first station 20 in which the first two-dimensional reinforcement mat 14 can be provided and arranged in the first plane. For this purpose, the first station 20 may be configured to have a first area 20a, in which the first reinforcement mat 14 is provided, and a second area 20b, in which the first reinforcement mat 14 is arranged in the plane. The two areas 20a and 20b may be spatially separated from each other.

[0019] Method 1 comprises a second method step 3 in which at least one second intrinsically curved, preferably ladder-shaped two-dimensional reinforcement mat 15 is provided.

[0020] Method 1 comprises a third method step 4 in which the at least one second reinforcement mat 15 is positioned and held in a second plane transverse to the first plane by means of at least one positioning device 16 which is driven to move relative to the first plane such that the two reinforcement mats 14, 15 overlap at intersection points 17.

[0021] Method 1 comprises a fourth process step 5 in which the two reinforcement mats 14, 15 are welded together at least at part of the intersection points 17 by means of at least one welding device 18, preferably by means of at least one welding robot, while the at least one second reinforcement mat 15 is held in the second plane by means of the at least one positioning device 16.

[0022] The system 19 comprises a second station 21 in which at least one second reinforcement mat 15 can be provided and welded to at least one first reinforcement mat 14, wherein the second station 21 comprises at least one positioning device 16 that is movable relative to the first level and at least one welding device 18, preferably at least one welding robot. Alternatively, process steps 3, 4 and / or 5 can also be carried out in spatially separate stations of the system.

[0023] Preferably, the system 19 may include a third station 33 in which at least one third, preferably straight and / or ladder-shaped, two-dimensional reinforcement mat 27 can be provided, and which includes at least one further positioning device 28 and at least one further welding device 30, preferably at least one welding robot.

[0024] Particularly preferably, the system 19 may include a fourth station 34 in which at least one fourth two-dimensional reinforcement mat 36, preferably which is substantially identical to the at least one first reinforcement mat 14, can be provided, and which includes at least one further positioning device 37 and at least one further welding device 39, preferably at least one welding robot.

[0025] The system 19 can also comprise more or fewer than four stations, for example, if process steps are combined in one station or distributed across several stations. Similarly, welding devices and / or positioning devices can also be combined or distributed.

[0026] The system 19 can comprise at least one, preferably more than one, carriage 24 which can pass through the stations 20, 21, 33, 34, preferably on rails, preferably wherein the carriage 24 has several gripping devices 25, in particular grippers, with which at least the at least one first reinforcement mat 14 can be fixed on the carriage, preferably wherein at least one guidance system 40 is provided with which the at least one carriage 24 can be guided through the system 19, particularly preferably wherein the at least one guidance system 40 comprises at least one rail guide.

[0027] A preferred production direction 35 consists in at least one carriage 24 passing continuously through the provided stations 20, 21, 33, 34, wherein a three-dimensional reinforcement structure 13 welded together from at least two, preferably more than two, two-dimensional reinforcement mats 14, 15, 26, 27, 31, 36 is sequentially built up on the at least one carriage 24.

[0028] The system 19 can optionally be designed such that a change of direction takes place when at least one car 24 is transferred from the third station 33 to the fourth station 34 and from the fourth station 34 to the first station 20.

[0029] The Figure 7Figure 19 shows the first station 20 and the fourth station 34 of the system, where stations 20 and 34 can be arranged adjacent to each other. This is particularly advantageous if similar or identical reinforcement mats 14 and 36 are processed in stations 20 and 34. In such a case, the reinforcement mats 14 and 36 can be efficiently supplied via a common dispensing table 47, which may have a curved surface. Alternatively or additionally, a transport device 46 can be used to arrange a first reinforcement mat 14 in the first, preferably partially curved, plane on the carriage 24, and also, as a positioning device 37, to position at least a fourth reinforcement mat 36 relative to the other reinforcement mats 14, 15, 26, 27, and 31 already arranged on the carriage 24.

[0030] In the first station 20, a reinforcement mat 14, which is later intended as an inner mat, is automatically transported to the carriage 24, where it is fixed by a gripping device 25 mounted on it, preferably comprising several gripper jaws.

[0031] The Figures 8 and 9Figure 21 shows a second station 21 of system 19. In station 21, reinforcement mats 15, 26, e.g., in the form of curved ladders, can be automatically fed and positioned. After a reinforcement mat 15 has been brought to a desired position by means of a positioning device 16, e.g., one of the side edges 22, 23 of the first reinforcement mat 14, a welding device 18, e.g., in the form of a welding robot, welds the reinforcement mat 15 directly to the reinforcement mat 14, while the reinforcement mat 15 is held by the positioning device 16. As soon as the reinforcement mat 15 has a stable connection with the reinforcement mat 14 at intersection points 17 by means of weld points, the positioning device 16 releases the reinforcement mat 15 and positions corresponding further reinforcement mats 26 at the next welding positions.

[0032] The Figures 10 and 11Figure 1 shows a third station 33 of system 19. In station 33, reinforcement mats 27, 31, e.g., in the form of straight ladders, can be automatically fed and positioned. After a reinforcement mat 27 has been brought to a desired position by means of a positioning device 28, a welding device 30, e.g., in the form of a welding robot, welds the reinforcement mat 27 directly to the first reinforcement mat 14 and / or to the reinforcement mats 15, 26, while the reinforcement mat 27 is held by the positioning device 28. As soon as the reinforcement mat 27 has a stable connection with the first reinforcement mat 14 and / or with the reinforcement mats 15, 26 at intersection points 29 by means of weld points, the positioning device 28 releases the reinforcement mat 27 and positions corresponding further reinforcement mats 31 at the next welding positions.

[0033] The Figures 12 and 13Figure 1 shows a fourth station 34 of the system 19. In station 34, a fourth reinforcement mat 36, functioning as an outer mat, can be automatically fed and positioned. After the reinforcement mat 36 has been brought to a desired position by means of a positioning device 37, a welding device 39, e.g. in the form of a welding robot, welds the reinforcement mat 36 directly at intersection points 38 with reinforcement mats already arranged on the carriage 24.

[0034] After the reinforcement mat 36 has been welded, the finished three-dimensional reinforcement structure 13 is lifted from the trolley 24, e.g. with a transport system, and transported to a subsequent process step, temporarily stored or made available for manual collection.
