DETAILED DESCRIPTION

[0053] FIG. 1 shows a tower segment 1 executed for building a tower 2 according to FIG. 4. The tower segment 1 is preferably a prefabricated concrete part. In a top view, individual tower segments 1 can be polygonal, circular or have the shape of a circular segment. The tower segment 1 has an interior 4 bounded by a wall 3, in which a supply structural segment 5 is arranged for fastening interior components (not shown). The supply structural segment 5 extends along a longitudinal axis 22 of the tower segment 1. Such interior components typically include components for the ongoing operation, just like components for assembly and maintenance purposes. For example, the internal installations can include ladders, wiring, power cables, lighting elements, elevators and the like. In FIG. 1, the supply structural segment 5 is arranged here in an assembly position 6, in which the supply structural segment 5 extends at an angle to the wall 3. Thus, the supply structural segment 5 is fully arranged inside the tower segment 1 in spite of its length, which largely corresponds to a height of the tower segment 1, and it neither projects above it at the upper edge 18 nor at the lower edge 17.

[0054] Here, the supply structural segment 5 comprises a supply scaffolding 7, which has at least one vertical strut 8. Preferably, two vertical struts 8 arranged parallel to one another are interconnected at least by means of a horizontal strut 9, so that an essentially stable supply scaffolding 7 is provided. To connect several vertical struts 8 to one another, they are preferably executed in an L-shaped profile and/or have a connecting piece or head plates in their longitudinal ends for screwing them together. To stabilize the supply scaffolding 7, diagonal struts can be provided (not shown) to connect the corners of the supply scaffolding 7 together and provide additional stability.

[0055] Furthermore, the supply structural segment 5 includes at least one fastening strut 10, which connects the supply scaffolding 7 to the wall 3 of the tower segment 1. Preferably, one fastening strut 10 is arranged in each case on the ends of the horizontal strut 9. So the supply structural segment 5 can be moved relative to the wall 3, the fastening strut 10 is equipped with two joints 11, 12. A first joint 11 connecting the fastening strut 10 to the supply scaffolding 7 allows the supply scaffolding 7 to be swiveled relative to the fastening strut 10. A second joint 12 connects the fastening strut 10 in such a way to the wall 3 that the fastening strut 10 can be folded upwards and downwards relative to the wall 3.

[0056] A tolerance compensation element, executed here in form of a guidance system 13, is executed here between the fastening strut 10 and the supply scaffolding 7 or supply structural segment 5, so that tolerances can be compensated when several supply scaffoldings 7 or supply structural segments 5 are connected to each other. The guidance system 13 comprises a first part 14 and a second part 15 connected in such a way to one another that the supply scaffolding 7 is movable in a transverse direction (i.e. perpendicularly to the longitudinal axis 22 and/or wall 3) to the tower segment 1. The first part 14 is preferably an elongated hole preferably executed on the fastening strut 10 and in which the second part 15, especially a screw, is movably arranged. The second part 15 is connected to the supply scaffolding 7, so that the displacement of the second part 15 to the first part 14 is transferred to it. Preferably, the first part 14—here the elongated hole—and the second part 15—here the screw—are simultaneously the first joint 11.

[0057] So the supply structural segment 5 can be held in the assembly position 6, it is additionally secured to the wall 3 by means of a fastening element 26. The fastening element 26 prevents the supply scaffolding from swiveling around the two joints 11, 12. To move the supply structural segment 5, the fastening element 26 is detachably designed so it can be removed from between the wall 3 and the respective supply structural segment 5.

[0058] The supply structural segment 5 furthermore includes a ladder segment 19 arranged between the supply scaffolding 7 and the wall 3 of the tower segment 1. The ladder segment 19 has adjusted rungs (not shown) between two hollow profile-shaped stiles 20 for ascending and descending. In the assembly position 6, the ladder segment 19 or supply scaffolding 7 extends essentially obliquely to the longitudinal axis 22, especially at an angle between 15° to 60°, preferably between 20° and 45°, and also to the wall 3 of the tower segment 1, which in a conical tower segment 1 can be inclined at an angle of up to 15° relative to the longitudinal axis 22. On their end facing an upper edge 18 of the tower segment 1, the stiles 20 have in each case a connecting element 23 executed in a way allowing the transfer of horizontal and/or tensile forces. On their end facing a lower edge 17 of the tower segment 1, the stiles 20 have a connecting element holding space 24. Likewise, the arrangement of connecting element 23 and connecting element holding space 24 can be reversed. To connect several ladder segments 19 to one another (cf. FIGS. 2 to 4), the connecting elements 23 of the ladder segments 19 of the one tower segment 1 are introduced into the connecting element holding spaces 24 of the stiles 20 of the ladder segment 19 of the other tower segment 1 and connected in a force-fitting manner if necessary. The connecting elements 23 are preferably incorporated into the connecting element holding spaces 24 of the stiles 20 in a form- and/or force-fitting manner. This procedure applies analogously to fall protection elements that are generally pre-mounted along the ladder segments 19 and connected to one another in a force-fitting manner.

[0059] According to an alternative embodiment (not shown), the ladder segment 19 is directly connected to the fastening struts 10. In this case, the supply structural segment 5 is largely executed by the ladder segment 19 alone. The second part 15 of the guidance system 13 is then fastened to one or several of rungs and/or stiles 20 of the ladder segment 19.

[0060] According to the execution of FIG. 1, the supply structural segment 5 is introduced in assembly position 6 into the tower segment 1 so it neither projects above the lower edge 17 nor above the upper edge 18 of the tower segment 1. When the tower 2 is built, the individual tower segments 1 can be mounted on top of one another without the projecting structural parts interfering with the assembly when placed on top.

[0061] FIG. 2 shows several tower segments 1 arranged on top of one another while forming horizontal joints 33 towards the tower 2. To erect the tower 2 using the tower segments 1, an upper tower segment 1a is arranged in each case on a lower tower segment 1b. In the tower segments 1a, 1b, a supply structural segment 5 has been pre-mounted in each case. The supply structural segment 5 of the upper tower segment 1a is shown in assembly position 6, in which the supply structural segment 5 neither projects above the upper edge 18 nor above the lower edge 17 of the tower segment 1a. Here, the fastening element 26 is arranged between the wall 3 and the supply structural segment 5 of the upper tower segment 1a. The upper tower segment 1a can thus be easily mounted on the lower tower segment 1b with a crane (not shown), without the projecting structural parts interfering with the assembly during placement above the lower edge 17 of the upper tower segment 1a.

[0062] A supply structural segment 5, which is in a connecting position 25, has also been arranged in the lower tower segment 1b. According to this execution, in the connecting position 25, the supply structural segment 5 projects above the lower edge 17 of the lower tower segment 1b. Furthermore, in the connecting position 25, the fastening strut 10 encloses an acute angle α with the longitudinal axis 22 of the tower segment 1. Here, for clarity reasons, the angle α between the fastening strut 10 and a parallel to the longitudinal axis 22 has been marked.

[0063] In FIG. 2, an additional lower tower segment 1 is arranged below the lower tower segment 1b. In the connecting position 25, the lower end 34 of the supply structural segment 5 of the lower tower segment 1b is connected to the upper end 35 of the supply structural segment 5 of the tower segment 1 lying below. Preferably, the L-shaped vertical struts of the supply structural segments 5 of the lower tower segment 1b and the tower segment 1 lying below are screwed together in the connecting position 25. Here, the connecting element holding spaces 24 of the lower tower segment 1b and the connecting elements 23 of the tower segment 1 lying below are interlocked (cf. FIG. 1, since the connecting point between the supply structural segments 5 is not apparent in FIG. 2). Here, the connecting point between the individual supply structural segments 5 is in each case somewhat below the assigned horizontal joint 33.

[0064] So the supply structural segment 5 of the upper tower segment 1a can be swiveled to the connecting position 25, the fastening element 26 (cf. FIG. 1) between the supply structural segment 5 and the wall 3 is detached at first. Then, the supply structural segment 5 is swiveled around both joints 11, 12 so that it now lies in the connecting position 25 just like the supply structural segments 5 of the tower segments 1, 1b lying below and can be attached to the supply structural segment 5 of the lower tower segment 1b. In this execution, the supply structural segment 5 in the connecting position 25 is now parallel to the wall 3 of the tower segment 1a assigned to it and is at a relatively short distance to it.

[0065] To summarize, the tower segments 1 are equipped with the supply structural segments 5 in the factory or at ground level on the construction site, so that they are in the assembly position 6 when the tower segments 1 are ready on the construction site. After such a tower segment 1 is mounted on another tower segment 1, the supply structural segment 5 of the tower segment 1 is swiveled into the connecting position 25 and a lower end 34 of the supply structural segment 5 is connected to the upper end 35 of the supply structural segment 5 of the other tower segments 1 lying below, so that the connecting position 25 is taken. Several tower segments 1, in which the supply structural segments 5 are arranged in each case in the connecting position 25, are joined together and shown in FIG. 3.

[0066] In FIG. 3, several tower segments 1 are arranged on top of one another and a lowest tower segment 1 is placed on a foundation 27 of the tower 1. The lowest tower segment 1 is also arranged on the foundation 27 with a supply structural segment 5 arranged, if necessary shortened, in the assembly position 6 (cf. FIG. 1). After the lowest tower segment 1 has been placed, the fastening element 26 (cf. FIGS. 1 and 2) between the wall 3 and the supply structural segment 5 is detached, so that the supply structural segment 5 can be moved in the connecting position 25, wherein it is swiveled around both joints 11, 12. Afterwards, as described based on FIGS. 1 and 2, additional tower segments 1 are arranged on the lowest tower segment 1 as corresponding upper tower segments 1a (see FIG. 2), wherein they are initially placed in each case in the assembly position 6 (cf. FIGS. 1 and 2) on the corresponding lower tower segment 1b (see FIG. 2), then the fastening element 26 is detached and wherein the supply structural segment 5 is subsequently moved to the connecting position 25. In the connecting position 25, the supply structural segments 5 arranged in each case one below the other, especially their vertical struts 8, are joined together. These steps are repeated until the tower 1 has reached a target height. By joining the individual supply structural segments 5 together, a supply structure 28 is formed that extends along a height of the tower 2 or along the longitudinal axis 22 of the individual tower segments 1. Since in the connecting position 25, the supply structural segments 5 or the entire supply structure 28 already extend parallel to a wall 3 of the tower segments 1 or, in the case of a linear tower wall, also parallel to a wall 3 of the entire tower 2, assemblers can already climb from the foundation 27 to one of the uppermost tower segments 1 immediately after the supply structure 28 is placed in the use position 31 (s. FIG. 4), described below.

[0067] Once the target height of the tower 1 or especially of the supply structure 28 is reached, an adapter piece 29 is placed on the uppermost tower segment 1. Like a tower segment 1, the adapter piece 29 is executed as a prefabricated concrete part for joining to another tower section, made of steel for example, or also to a nacelle of a wind turbine. An adapter platform 30 has been arranged in the adapter piece 29, which after the adapter piece 29 has been placed on the uppermost tower segment 1, is lifted onto it and fastened there. The adapter platform 30 runs essentially perpendicularly to the longitudinal axis 22 of the tower 1. In the adapter platform 30, an opening 32 for climbing through has been executed and arranged in such a way that someone can climb from the supply structure 28 directly to the adapter platform 30.

[0068] In FIG. 3, the supply structure 28 is or the individual supply structural segments 5 are arranged in the connecting position 25, in which the individual supply structural segments 5 are arranged folded downward around the respective joints 11, 12. Thus, the supply scaffoldings 7 and their ladder segments 19 extend preferably in the connecting position 25 in essentially parallel fashion to the wall of the tower segments 1.

[0069] On the other hand, FIG. 4 shows the tower 1 with a supply structure 28 arranged in a use position 31. Also in the use position 31, the supply structural segments 5 with the supply scaffoldings 7 and the ladder segments 19 extend preferably parallel to the wall 3 or at a slight angle to it. The supply structure 28 is lifted and swiveled out of the connecting position 25 around the individual joints 11, 12 in the use position 31 and fastened onto the adapter platform 30. In the swiveling procedure, care must be taken that the fastening struts 10 in the connecting position take the correct angle α (see FIG. 2) relative to the longitudinal axis 22 to prevent the supply structural segments 5 from tilting on the fastening struts 10.

[0070] As is apparent when comparing with FIG. 2, the supply structural segments 5 or the supply scaffoldings 7 and their ladder segments 19 are at a greater distance to the wall 3 in the use position 31 than in the connecting position. According to this drawing, the individual supply structural segments 5 in their corresponding use position 31 project above the upper edge 18 of the respectively assigned tower segment 1 with their upper end 35. The fastening strut 10 extends essentially horizontally and thus perpendicularly to the longitudinal axis 22 of the tower 1 in the interior 4 of the tower 2. Between the wall 3 and the supply structure 28 or the supply structural segment 5 and the fastening strut(s) 10, a clearance 38 is formed inside which an elevator cabin and, when necessary, also additional internal installations can be arranged. It is advantageous if cable ducts are fastened outside this clearance 38, i.e. on the external side or on the side of the supply structural segments 5 or fastening struts 10 that faces away from the clearance 38, as this facilitates the installation of the cables.

[0071] Finally, another bottom supply structural segment 5 is arranged between a lower end 16 of the supply structure 28 and the foundation 27, which continues the supply structural segments 5 arranged on top to a surface 21 of the foundation 27.

[0072] FIGS. 5a, 5b and 7 show an alternative embodiment of the supply structure 28, wherein the same reference signs are used for features whose design and/or mode of operation are identical and/or at least similar compared to the embodiment shown in FIGS. 1 to 4. If they are not explained in detail once again, their design and/or mode of operation corresponds to the design and/or mode of operation of the features already described above.

[0073] The supply structure 28 has several supply structural segments 5 joined together. Two supply structural segments 5 at a time are joined together by means of joints 11, 12, so that the supply structure 5 can be folded together in the assembly position 6. The supply structure 28 that is in the assembly position 6 according to FIG. 5a is lifted in the folded state to the already erected tower 2. Alternately, before erecting the tower 2, the supply structure 28 is placed on the foundation 27 and then the tower 2 is erected.

[0074] Once the target height of the tower 2 is reached, the supply structure 28 is lifted from the assembly position 6 to the unfolded use position 31 (not shown here) and joined to the adapter platform 30 of the tower 2 according to FIG. 4. This state is shown in FIG. 5b, wherein the use position 31 has not been reached yet. The joints 11, 12, around which the supply structural segments 5 are lifted from the assembly position 6 to the use position 31, are executed as double joints.

[0075] Supporting elements to secure and guide an elevator are preferably arranged on the supply structure 28.

[0076] To move the supply structure 28 from the assembly position shown in FIG. 5a to the use position 31 (not shown), the supply structure 28 is preferably moved to an unfolded connecting position 25 first, as shown in FIG. 7.

[0077] In the connecting position 25, the supply structure 28 is fastened to the tower 2 or tower section in a suspended way, as described above, and only then pulled to the use position 31, in which the supply structure 28 extends towards the wall 3, as shown similarly in FIG. 4. To do this, a rope 36 fastened to the supply structure 28 in the area of each joint 11, 12 is connected to the suspended supply structure 28. Here, the rope 36 is preferably fastened to the supply structure 28 in each case just above and additionally just below the joints 11, 12, thereby stiffening it in its longitudinal direction. On the lower end of the supply structure 28, the rope 36 is guided around a pulley 37 arranged close to the wall 3. Thus, by pulling on the end of the rope 36, it is possible now to pull the supply structure 28 from the connecting position 25, in which it essentially hangs down perpendicularly, to the use position 31, in which the supply structure 28 extends parallel to the wall 3.

[0078] FIG. 6 shows a second alternative embodiment of the tower segment 1 with the supply structural segment 5, wherein for features that compared to the embodiments shown in the previous figures have the identical and/or at least a similar design and/or mode of operation, the same reference signs are used. If they are not explained in detail once again, their design and/or mode of operation corresponds to the design and/or mode of operation of the features already described above.

[0079] In FIG. 6, two tower segments 1a and 1b are arranged on top of each other. The supply structural segment 5 of the upper tower segment 1a is in an assembly position 6 and the supply structural segment 5 of the lower tower segment 1b is in a connecting position 25. In the assembly position 6, the supply structural segment 5 projects above an upper edge 18 of the tower segment 1a, but not its lower edge 17. This makes it possible to place the upper tower segment 1a on the lower tower segment 1b without having to consider the structural parts that are above the lower edge 17.

[0080] After placing the upper tower segment 1a on the lower tower segment 1b, the supply structural segment 5 is folded from the assembly position 6 to the connecting position 25 and a lower end 34 of the supply structural segment 5 is joined to an upper end 35 of the supply structural segment 5 of the lower tower segment 1b. Here, an intermediate piece (not shown) can be arranged between both supply structural segments 5 to join the two indirectly together. Likewise, a tolerance compensation element can be provided. As described above, the supply structural segments 5 can be connected to the connecting elements 23 and connecting element holding spaces 24. Alternately, the supply structural segments 5 are directly joined together, especially screwed together.

[0081] Contrary to the embodiment shown in FIGS. 1 to 4, the supply scaffolding according to FIG. 6 is fastened to the wall 3 of the respective tower segment 1a, 1b with two fastening struts 10. A first joint 11 and a second joint 12 are assigned to each fastening strut 10, so that they can be swiveled both relative to the wall 3 and also relative to the supply structural segment 5. As a result of this, the supply structural segment 5 is both in the assembly position 6 and in the connecting position 25, and in the use position 31 (not shown here) it is parallel to the wall 3 of the tower segment 1a or to the wall 3 of the tower 2. In the use position 31, the fastening struts 10 extend likewise essentially horizontally or perpendicularly to the longitudinal axis 22 of the tower 1 in the interior 4 of the tower 2. Moreover, in the use position 31, the supply structural segment 5 is also at a greater distance to the wall 3 than in the connecting position.

[0082] Preferably, the joints 11, 12 can be locked so the supply structural segment 5 can be held in the assembly position 6, connecting position 25 and/or use position 31.

[0083] The present disclosure is not limited to the embodiments shown and described. Variations within the framework of the patent claims are just as possible as a combination of the features, even if they are shown and described in various embodiments.
