    [001] The present invention relates to a wind energy installation tower segment as well as a wind energy installation tower featuring a plurality of such tower segments, and a wind energy installation with a corresponding tower. Furthermore, the invention relates to a method for producing several such tower segments.
    [002] A modern wind energy installation currently usually comprises a foundation, on which a wind energy installation tower is placed, which supports a gondola in which a generator is received, whose rotor is rotated by an aerodynamic rotor for generation of energy with corresponding wind. Towers of such wind energy installations can have heights greater than 100 m. In addition to steel towers, concrete towers made of reinforced concrete and/or prestressed concrete are often also used. In this case, by means of a concrete tower, it must be understood that it is predominantly made of concrete. Often an upper thread can be produced from steel.
    [003] Such a tower has a substantially tubular shape and traditionally differs from a rigidly cylindrical shape in that it decreases in diameter from the foundation towards the gondola.
    [004] Such a concrete tower is traditionally constructed of several finished parts of concrete. On the one hand, such a tower has in the vertical direction several tower segments arranged one above the other, which are usually firmly tensioned or fixed in the vertical direction by means of tension cables. Each of these tower segments, at least, however, tower segments from the lower region of the concrete tower, is assembled from side surface segments. For example, a tower segment consisting of two half-shells which fundamentally respectively form a 180 degree segment of the tower segment, can be joined. These tower segments are most often industrially prefabricated as finished parts of concrete and are assembled and connected at the time of tower construction. The need to subdivide the tower segments into multiple segments is conventionally based on the necessary transport of the elements from their construction site to the wind power installation assembly site.
    [005] Tower segments of a tower section, which may also be referred to as a tower base, are traditionally assembled in place at vertical top corners. At these top corners, sections of the reinforcement protrude outwards, so that the segments can be connected to each other here by means of a bolt. The remaining vertical joints are then filled with mortar.
    [006] In this case, it is disadvantageous that a lot of manual work is required to connect the tower segments to each other. Furthermore, the application of mortar holds the danger of corrosion of the reinforcement segments in this region, in particular when the application of mortar does not take place in a specialized manner or is defective. In this case, flaws or failure points themselves appear in the careful construction. Such points of failure can be, for example, enclosed water or air bubbles or capillaries leading outward from the reinforcement.
    [007] Furthermore, the positioning accuracy that can be achieved of such tower segments to each other limits and usually lies in the region of ± 10 mm. Furthermore, the application of mortar can be problematic at low temperatures during winter.
    [008] Therefore, the invention aims to eliminate or reduce at least one of the problems mentioned. In particular, a solution should be proposed in order to simplify the connection of several tower elements to one another and/or improve the connection with a view to positional accuracy and/or reliability and/or durability. At least one alternative solution must be proposed.
    [009] According to the invention, a tower segment according to claim 1 is proposed.
    [0010] Such a tower segment is configured as a casing segment and is prepared for the purpose of being joined with at least one other of such or similar tower segment to form a tower section, which is also referred to as a tower joint . By a tower section is to be understood, in this context, a tube-shaped section, closed in the circumferential direction. A tower has several tower sections placed one above the other.
    [0011] The tower segment has a reinforced concrete body and thus a concrete body provided with a reinforcement. For assembling with at least one other tower segment, two butt joints are provided for end-to-end placement of another particular similar or identical tower segment, which is arranged in the same plane, in order to thus be able to produce a tower section. Such a butt joint is a surface and has substantially or at most a length in accordance with the height of the tower segment and a width in accordance with the thickness of the tower segment, hence the wall thickness of the tower segment. In other words, such a butt joint corresponds to a cut surface of a vertical cut through the tower segment, the butt joint possibly being somewhat smaller and in particular somewhat narrower.
    [0012] In the region of each butt joint, at least one connecting body is crimped and anchored within it. Such a connecting body is prepared and provided for the purpose of being connected with another connecting body of the adjacent tower segment. Here, both connecting bodies can contact each other, or at least one other material, in particular concrete, can be provided between them. The connecting body has an anchor wall arranged substantially parallel to the respective top or butt joint, to absorb a tensile load oriented transversely to the top and transversely to the anchor wall. Here, a firm connection of the connecting body with a connecting body of another tower segment can be realized. Hereby, a firm connection of the aforementioned tower segments to each other is achieved by anchoring or fixing the connecting body to the concrete body.
    [0013] In this case, several connecting bodies are preferably arranged along a butt joint, in particular at identical distances.
    [0014] According to the invention, two tower segments can thus be firmly connected end-to-end. A high accuracy is achieved in this connection, which is substantially determined by the manufacturing accuracy of the tower segments.
    [0015] Preferably, the tower segment is a prefabricated part of concrete. Such a prefabricated concrete part can be prefabricated industrially, whereby a high quality and thus strength of the reinforced concrete body can be obtained. Furthermore, a high accuracy and quality of the butt or butt joint can be obtained.
    [0016] Preferably, the connection body is configured as a connection box or steel niche. Next, the terms junction box and steel niche are used interchangeably.
    [0017] The junction box preferably has several, in particular three, side walls that are adjacent to the fixing wall, to thus form a hollow space, in particular a niche. The side walls and the fixing wall are in this case firmly connected to each other. The connecting body here also has an open side, accessible from the outside, in which the connecting body with reinforcement bars embedded in the reinforced concrete body is firmly connected, so that in this way the anchoring is carried out. of the connecting body in the reinforced concrete body. The hollow space is accessible through the open side, accessible from the outside. That is, access to the hollow space can be gained from the outside of the tower segment. In this case, the tower segment is preferably constructed in such a way that access to the hollow space can be gained, more precisely, from the outside of the tower segment, however from the inside of a constructed wind power installation tower or the be built. This hollow space open towards the outside or the niche open towards the outside would not, therefore, not be exposed or would not be exposed in all cases to the influences of time.
    [0018] According to an embodiment, a tower segment is proposed, which is characterized in that a first of the side walls is situated opposite the open side and at least one reinforcing bar connected with the first side wall is inclined relative to at least one rebar connected to one of the other side walls at an angle of inclination, the angle of inclination preferably being in the region of approximately 2-8 degrees, more preferably in the region of approximately 3 - 5 degrees and in particular is approximately 4 degrees.
    [0019] By providing for the slants of the rebars relative to one another and thus fastening rebars with different inclinations to the connecting body, forces can be deflected in the correspondingly different direction. By this, the tube-like structure of the wind power installation tower and thus the domed shape of the tower segment can be taken into account. The angle of inclination may be in the region of 2 to 8 degrees, which may depend in particular on the diameter of the tower in the region of the corresponding tower segment. The smaller the diameter, the larger the tilt angle can be selected. For the usual diameters, inclination angles of 3 to 5 degrees are favourable, in particular 4 degrees.
    [0020] Preferably, the connecting body is arranged in such a way in the reinforced concrete body, in particular concreted, that it is accessible from the outside. In particular, it is also possible to access the connection made via the connecting body with another connecting body of an adjacent segment. The reinforcing bars are, on the contrary, arranged in such a way and connected with the connecting body that they are completely enclosed in the tower segment and thus are inaccessible from the outside. Thereby, corrosion protection can be sustainably achieved for the reinforcing bars. The reinforcement bars are in this case enclosed or substantially encased in concrete and, at the connection location to the connecting body, they are enclosed by the connecting body or shielded from the outside.
    [0021] A preferred attachment of the reinforcing bars with the connecting body is carried out by means of welding. In this way a long-lasting and resistant connection can be achieved, through which, in addition, a high power transmission can be realized.
    [0022] Another favorable embodiment proposes that the attachment wall is closed approximately with the butt joint and/or that the attachment wall has at least one attachment opening for the passage of at least one clamping device, in particular of a screw, in order to transmit, through this clamping device, a tensile load from another tower segment to the fixing wall.
    [0023] The fact that the attachment wall closes approximately with a butt joint means that the connecting body is embedded in such a way in the reinforced concrete body that an outer surface of the connecting wall forms a part of the top, therefore the contact surface to an adjacent segment. Thereby, when placing two segments side by side in dirty butt joints and corresponding arrangement of the connecting bodies on the two butt joints, a direct contact of the connecting bodies is established with each other. Correspondingly, a firm connection of the connecting bodies and thus the segments can be achieved in a simple way. Both segments are thus fixed directly end-to-end so that an application of mortar can be substantially or totally omitted. Eventually, an elastic sealing mass can be provided.
    [0024] Also for the case where the fixing wall is closed approximately with the joints, reinforcing bars can be connected in such a way with the connecting bodies that they are not accessible from the outside. In other words, the reinforcing bars can be attached somewhat set back from the top.
    [0025] By providing at least one fastening opening in the fastening wall for the passage of a fastening device, such as a screw, a fastening possibility and finally also a fastening possibility of the two connecting bodies between itself can be provided in a simple way. Thus, such a screw or threaded rod connects two adjacent connecting bodies of two adjacent tower segments. Since the connection body is provided as a connection box with a hollow space or niche accessible from the outside, then, in this hollow space or in this niche, the fixation can be carried out, in particular the firm screwing of these two connection bodies to be connected between themselves.
    [0026] Thereby, a firm and also very accurate end-to-end connection of two segments can be obtained, because the firm connection or firm tightening is not effected in the region of the contact surface or joint, but rather in the hollow spaces or niches accessible from the outside. To finally act additionally against corrosion, in particular also corrosion in the connecting body, it is proposed, after completion of the firm connection, to provide a rubber formwork for the hollow spaces or niches.
    [0027] According to the invention it is further proposed to build a wind energy installation tower at least in part with the tower segments according to the invention. In this case also at least two tower segments are joined to form a tower section or tower lock, wherein the tower segments are placed end to end next to each other and are connected to each other by means of connecting bodies . Such tower segments are then arranged on top of each other, with the highest placed tower segments having the usually increasingly smaller diameters. In this case, the tower segments are arranged on top of each other in such a way that adjacent tower sections have butt joint or longitudinal joint formed in the region of the butt joint offset from each other.
    [0028] Preferably, a wind power installation is provided which has a wind power installation tower according to the invention has or several tower segments according to the invention. By using tower segments according to the invention or a tower according to the invention, the service life of the wind energy installation can be extended or the maintenance intervals can be extended.
    [0029] Furthermore, according to the invention, a method for producing multiple tower segments for a wind power installation tower is proposed according to claim 11.
    [0030] According to the method, several tower segments are simultaneously produced in a form or mold or formwork. For this purpose, a reinforcement and the connecting bodies, including its anchorage, are prepared in the corresponding shape or formwork, respectively, for each of the tower segments to be produced in the same shape. Anchoring can mean, in this case, a welding of the connecting bodies with some reinforcement reinforcement bars. Here it is not important whether such welding is carried out on site in the form or mold or previously in another preparation step.
    [0031] With the reinforcement and connecting bodies in their positions, the form or mold can be filled with concrete. The concrete must then harden until it can be removed. A removal usually means that the concrete then remains in place and at the applied point and then only the formwork or formwork, which here is most often configured in several parts, is removed.
    [0032] The form of concrete or formwork is provided for a complete tower section, therefore a tubular side surface completely closed in the circumferential direction. A corresponding concrete part, in particular a corresponding reinforced concrete body, is thus formed after the hardening described above. The proposed connecting bodies are always correspondingly arranged in pairs, more specifically always a respective connecting body for every two adjacent tower segments.
    [0033] For transport, these thus formed tower segments are separated, such as, for example, into two half-shells. These segments are then reassembled at the wind power installation assembly site as they have already been arranged relative to one another in the production in the form of concrete.
    [0034] Thereby, a high production accuracy, in particular a very good adaptation of the tower segments to be connected side by side, can be obtained, as these segments have already been forcibly adapted to each other in shape. Separation of the tower segments thus produced in a concrete form can, for example, be achieved by providing a separating layer at the joints, such as a separating plate.
    [0035] Through the use of closing means, such as, for example, a rubber formwork, it can be avoided that the hollow space or niches of a connecting body are filled when filling the concrete in the form.
    [0036] According to the invention it is proposed, in addition, a connecting body, in particular steel niche, as it has already been explained above in connection with a tower segment. This connecting body comprises: a connecting wall for placing a second connecting body on a connecting wall; a first side wall connected with the connecting wall, two second side walls connected with the connecting wall and the first side wall, so that the connecting wall, the first side wall and the two second side walls together form a niche.
    [0037] By producing such a connecting body, a tower segment can be thus shaped and the structure of a wind power installation tower consisting of such tower segments can be simplified.
    [0038] Preferably, as connecting bodies, two different connecting bodies are provided which are respectively adapted to each other. In the top region, where these bodies are contacted with each other, one of them has a cavity and the other has a corresponding elevation. Preferably, such connecting bodies are then provided in pairs and mounted in such a way on the tower segments that they come into contact with each other in the corresponding connecting bodies, in particular steel niches, and the corresponding regions engage with each other. With this, it is also proposed to provide a tower segment that has two top sides for contacting on one or two top sides of another tower segment. For one joint side a first connecting body with a cavity is then produced and on the other joint side at least one second connecting body with a corresponding elevation is provided. In this way and manner, several tower segments can be provided and then assembled or assembled in correspondence with the structure of a wind energy installation tower.
    [0039] The invention will be explained below, by way of example, based on examples of realization with reference to the attached figures.

    [0051] Figure 12 shows a first and second connection bodies connected to each other in a side view.
    [0052] In the following, identical reference numerals may designate similar elements of different embodiments.
    [0053] Figure 1 shows a partial region 2 of a wind power installation tower according to the present invention in a partially cut away, perspective view. Partial region 2 is composed of two tower sections or tower housings 4, which are arranged one above the other on their front surfaces 5. Each tower section 4 is respectively composed of two tower segments 1. Always two tower segments 1 are joined at the top 6. In the region of two ends 6 there is respectively a joint 8, which, however, is relatively narrow and fundamentally negligible. Effectively, a joint is avoided through the end-to-end arrangement. In the region of each end 6 are arranged six connecting bodies, of which the niche 10 is inaccessible from the outside, it can be recognized. In each joint 8, six pairs of connecting bodies and thus six pairs of niche 10 are thus arranged. The connecting bodies are in this case connected in pairs. Screws can be firmly tightened into the recess for connection.
    [0054] The joints 8 of the lower tower section 4 are arranged offset with respect to the joints 8 of the depicted upper tower section 4 of the wind power installation tower region 2. With this, the tight 8 of the overlapping arranged tower sections 4 are not arranged aligned, whereby the overall stability of the wind power installation tower can be improved.
    [0055] The displacement of the connecting bodies 12 and thus of the niches 10 can be especially unambiguously recognized in the top view of figure 2. Figure 2 clearly shows, furthermore, that each tower section 4 is composed of two segments of semi-shell-shaped tower 1. Figures 3 and 4 show other views of the partial region 2 of the wind energy installation tower.
    [0056] In figure 5 are shown isolated in another view, two tower segments 1, which are placed next to each other by their tops 6, and are connected. The cut-out part of figure 6 illustrates the arrangement of two tower elements 1 in the region of its top 6. Always two connecting bodies 12, of which only one part in figure 5 can be recognized, are arranged against each other and interconnected in the top region 6 and thus in joint region 8. For this purpose, each connecting body 12 has a connecting wall 14.
    [0057] In this case, each connecting body 12 is embedded or concreted in such a way in the tower segment 1 that it closes the respective connecting wall 14 with the respective top 6. Since respectively a connecting body 12 of a tower segment 1 is arranged at the same height as a connecting body 12 of another tower segment 1, their connecting walls 14 respectively contact in the adjacent top region 6 or joint 8. By means of paired provision of two connecting bodies 12, these can thus be directly interconnected and firmly screwed together, to thus obtain a firm connection of the tower segments 1 with one another.
    [0058] From figure 6 it is also clear that the two tower segments 1 can be laid flat next to each other in the region of their top 6. The joint 8 is fundamentally increasingly reduced and appears basically still on the surface.
    [0059] From figures 1 to 6 it can be further inferred that the niches 10 are accessible from the outside of the respective tower segment 1, in this case, however, they are accessible from the interior of the wind energy installation tower. In particular, figure 1 also shows in the representation to the right, below, a joint 8, which is directed towards the outside of the tower. There, no niche 10 can be recognized and is therefore not accessible from an outer side of the tower.
    [0060] Figure 7 shows a top view of a cut-out, partially cut-out part of two tower segments 1 placed next to each other. It can be seen that, for a better overview, any cut surfaces are not provided with a crosshatch. The two tower segments 1 according to figure 7 are placed next to each other in the region of their top 6. Figure 7 does not show here any intermediate space between the tops 6.
    [0061] The structure of the connecting body 12 becomes clear through the sectional view and the enlarged representation, which substantially respectively present a connecting wall 14 which, which are located next to each other in the region of the tops 6. Each connecting body 12 has a first side wall, which cannot be recognized above all in the representation of figure 7. Furthermore, each connecting body 12 is shown a second side wall 18. Each second side wall 18 is respectively connected with the corresponding connecting wall 14.
    [0062] To the first side wall are fixed first reinforcement bars 20 and to each second side wall 18 are fixed second reinforcement bars 22. The first reinforcement bars 20 are slightly inclined with respect to the second reinforcement bars 22, where in shape of realization shown the slope is approximately 4 degrees. Eventually, other slopes can be provided between reinforcing bars.
    [0063] With this, the connecting bodies 12 are fixed with each other in the region of the connecting walls 14. Occasional forces are transferred from the respective connecting wall 14 to the first side wall and the second side walls 18 and from there through the first reinforcing bars 20 and second reinforcing bars 22 are led forwards to the respective tower segment, in which the reinforcing bars 20 and 22 and thus the connecting bodies 12 are anchored.
    [0064] The perspective representation of figure 8 shows a connection body 12, which is configured as a connection box or steel niche. It has a connecting wall 14 with a first side wall 16 and two second side walls 18 connected to that connecting wall 14. The connecting wall 14, the first side wall 16 and the two second side walls 18 together form a niche. To each of the second side walls 18 are respectively attached two second reinforcement bars 22 and to the first side wall 16 four first reinforcement bars 20 are attached. Figures 8 to 11 show the reinforcement bars 20, 22 with a limited length. The reinforcement bars 20,22 can, however, be configured longer, and in an anchorage in the respective tower segment 1 a connection with other reinforcement elements can be provided in addition.
    [0065] In Figure 8, in addition, two connection openings 24 are shown in the connection wall 14. These connection openings 24 are fundamentally shaped as perforations 24 and are suitable for allowing a screw, in which a head, to pass through them. of bolt or a bolt nut may contact on a surface, facing niche 10, of the connecting wall 14.
    [0066] The top view in figure 9 on the connecting body 12 shows a second side wall 18 as well as a part of the connecting wall 14. Figure 9 is designated as the top view, as the present view corresponds to an observation direction from top to bottom for the case of an intended arrangement in an installed wind power installation tower. The inclination between the first reinforcement bars 20 and the second reinforcement bars 22 is designated as the inclination angle 26 in Figure 9.
    [0067] Figure 10 shows a view of the niche 10 of the connecting body 12. The niche 10 is configured between the first side wall 16, the connecting wall 14 and the two second side walls 18. From figures 8 to 10 is it is clear, furthermore, that the reinforcing bars 20, 22 are arranged somewhat set back behind the connecting wall 14.
    [0068] The front view of Figure 11 illustrates the arrangement of the connecting openings 24 in the connecting wall 14 and that the connecting wall 14 is fundamentally embedded on three sides, more specifically by the first side wall 16 and by the two second side walls 18 Also, the connecting wall 14 and thus the connecting openings 24 are engaged on three sides by the first and second reinforcing bars 20, 22, to thereby finally obtain a load removal through the connecting wall 14 for the bars of reinforcement 20, 22 and from there to the corresponding reinforced concrete bodies of a tower segment.
    [0069] Figure 12 shows a first connecting body 30, which is firmly interconnected and screwed with a second connecting body 32 by means of screws and nuts 40 or 42. The connecting bodies 30, 32 are placed here one by one. on the other side in the region its connecting walls 14' or 14". In the region of the connecting wall 14', the first connecting body 30 has a cavity 34. This cavity thus also has a cavity relative to a top 6' of the first connecting body 30. The second connecting body 32 has, for this purpose, as a Pendant a raised region or a projection or an elevation 36 in the region of a connecting wall 14". This elevation 36 in this case also rises from a top 6" and is intended for the purpose of being inserted in the recessed region or in the cavity 34, as this is shown in figure 12. Hereby, the connection properties are improved, and it can be avoided, in all cases, for the first connection body and the tower segment, in which it is embedded, also with slight manufacturing tolerances, an overhang of the connection body, more specifically of the steel niche shown.
