    The invention relates to a foundation for a wind power plant with a stand ring made up of prefabricated concrete elements and divided into a plurality of circumferential sections, with a stand area for a wind power plant tower and a plurality of support elements which extend radially outward from the stand ring, the stand ring being supported by strut ribs on the support elements
    The invention further relates to a wind turbine with a wind turbine tower comprising a rotor, the wind turbine tower being mounted on a foundation.
    WO 2004/101898 A2 discloses a foundation for a wind power plant. As described there, the manufacture of the foundation of onshore wind turbines requires a lot of manual and administrative effort, and the production is very time-consuming. In view of the increasing dimensions of modern wind turbines, the foundation is exposed to very high loads and must be dimensioned accordingly. Today's wind turbines have a tower with a height of up to 150 m and generate up to 6 MW. In the majority of cases, the tower or mast of wind turbines is made of reinforced concrete and is built using prefabricated concrete elements. Alternatively, the wind turbine tower can also be formed by a steel structure.
    Before the emergence of foundations from prefabricated prefabricated concrete parts, the foundations for wind turbines were essentially excavated from an excavation pit, installation of a granular substructure, construction of a foundation component, execution of the necessary / 30
    Formwork and reinforcement work and subsequent filling of the excavation pit with in-situ concrete were made, the concrete being transported as ready-mixed concrete by truck mixers to the work site and poured into the excavation pit. The central foundation component usually has a hollow cylindrical configuration and has generally been prefabricated and transported as a unit to the respective assembly site.
    The manufacture of a windmill foundation by in-situ concrete has a number of disadvantages. It requires complex logistics for planning the manufacturing activities on the construction site and is associated with time-consuming and costly operations at the construction site with regard to the erection of the formwork and the reinforcement structure as well as the transport and pouring of the concrete. This is particularly true in view of the fact that more than 1000 m 3 of concrete may be required for large foundations.
    In order to improve the construction process of a foundation, it was already proposed in WO 2004/101898 A2 to build the foundation using prefabricated concrete elements. Such concrete elements are manufactured in a precast concrete plant and transported to the work site, where they are positioned using a crane and then connected to one another. In this way, the duration of the construction processes at the workplace can be reduced considerably. The prefabricated concrete elements, when connected to each other, form a foundation with a central base ring and a plurality of support elements, each of which protrude radially outward from the base ring. Every prefabricated / 30th
    Concrete element forms one of the support elements and an associated ring section of the base ring. The ring sections of the base ring are connected to each other by screwed flanges. Like in the
    WO 2004/101898 A2 describes, the prefabricated concrete elements can be steel reinforced. After the foundation has been formed, the tower or mast of the windmill is erected on the base ring and fastened to the base ring using anchor bolts.
    By using prefabricated concrete elements, production can be carried out in a controlled environment, so that the quality of the hardened concrete can be improved. From a financial point of view, the molds used in a prefabrication plant can be reused many times before they need to be replaced, so that the cost of the mold or formwork per unit is lower than that of in-situ concrete manufacturing, each time a dedicated one erected formwork required. The formwork can be used several times, but must be transported from place to place and cleaned accordingly.
    Wind turbines are exposed to loads and stresses of a specific nature that must be absorbed by the foundation. The wind itself works in an unpredictable and changeable way. On the other hand, with ever larger systems, dynamic load components due to vibrations and resonances affect the structure. Furthermore, towers with a height of 100 meters and more transfer considerable eccentric loads to the foundation due to the tilting moment that occurs. The concrete of the foundation must withstand compression, which is in / 30
    occurs in the compressed zone, and the reinforcement structure of the concrete must absorb the tensile forces in the opposite part of the foundation, because the concrete itself has a relatively low tensile strength. Foundations made from prefabricated reinforced concrete elements have the advantage that the performance and quality of the concrete, as well as the quality of manufacture, in particular the post-treatment and hardening process, are higher, so that there is less risk of crack formation and greater resistance to dynamic and static loads are. This applies in particular because the concrete hardens under controllable conditions and there is therefore no weather risk on the construction site.
    While the use of prefabricated concrete elements thus has a number of advantages over casting a foundation from in-situ concrete, the assembly of the prefabricated concrete elements into the finished foundation, which is done by screwing flanges onto the ring sections of the base ring, is considered to be in need of improvement. Sometimes foundations for large wind turbines have base rings made up of twelve or sixteen ring sections and more, so that the individual prefabricated concrete elements can remain small enough for transport with conventional trucks. As a result, hundreds of screws have to be set to manufacture the foundation, which is naturally time-consuming and requires a very precise initial positioning of the concrete elements to be connected to one another in order to be able to insert the screw bolts into the corresponding holes on the flanges.
    / 30 ♦ ·········· • ::: .5. · • · · · · «I
    The invention is therefore based on the object of improving a foundation of the type mentioned in such a way that assembling the ring sections to form the finished foundation can be done less time-consuming than assembling by screwing and not too great an accuracy when aligning the concrete elements to one another before being joined to the Day must be laid.
    To achieve this object, a foundation of the type mentioned at the outset is further developed in accordance with the invention in such a way that the base ring has at its end forming the base surface a circumferential projection which extends radially outward from the base ring and has at least one channel provided in the projection and extending in the circumferential direction for receiving a tensioning cable.
    By creating a circumferential projection which extends radially outward from the standing ring and which in the upper region, i.e. is at the end with the footprint of the base ring, the possibility is created without screwing the prefabricated concrete elements to find enough, because at least one tension cable, but usually a plurality of tension cables for tightening the prefabricated concrete elements in the upper area of the foundation can be carried out to a relatively large extent. A tensioning cable guided on a large scale can develop a better tensioning and joining force than tensioning cables that run on a small scale, so that the measure according to the invention achieves highly efficient tensioning of the prefabricated concrete elements. Consequently, the / 30
    Concrete elements are largely or completely dispensed with. For the insertion and tensioning of the tensioning cables, it is sufficient if the prefabricated concrete elements are positioned as close as possible to each other at the desired location, although no exact alignment of the boreholes has to be done. The tensioning cable or the plurality of tensioning cables can then be inserted into the channel running in the projection and pulled together. The prefabricated concrete elements are pulled together and aligned with each other and the finished foundation is obtained without screwing.
    An additional bracing in the upper area of the foundation can take place if the base ring has at its end forming the base surface a circumferential projection which extends radially inward from the base ring with at least one channel provided in the projection and running in the circumferential direction for receiving a tensioning cable, as is the case here corresponds to a preferred embodiment of the present invention. The tension cables in the inner projection are less favorable for exerting a tension force due to the smaller extent than those in the aforementioned external projection, but a tension cable or a plurality of tension cables in this projection nevertheless contributes to the overall strength of the foundation to a not inconsiderable extent can therefore be used with advantage in connection with the present invention.
    According to a preferred embodiment of the present invention, the support elements have at least one channel running in the circumferential direction for receiving a tensioning cable. The support elements extend like the / 30:: j:. · . ·· j. = External protrusion from the base ring to the outside and can therefore also contain cable channels for tensioning cables, which due to the relatively large size can exert a very high tension force on the base ring assembled from the prefabricated concrete elements or on the foundation. Within the scope of the present invention, the at least one channel for receiving a tensioning cable is therefore an ideal addition to the at least one channel provided in the circumferential direction on the outside of the standing ring for receiving a tensioning cable.
    To further increase the strength of the foundation assembled according to the invention without or largely without screw connections, it is provided according to a preferred embodiment of the present invention that the support elements of adjacent ring sections abut one another in a radially inner region. The abutting support elements, ie the abutting side surfaces, can absorb high frictional forces and thus contribute significantly to the overall strength of the foundation according to the invention. This applies above all when the support elements have at least one circumferential channel for receiving a tensioning cable, as described above. Tension cables in the support elements press them against each other with great force and in this way create a surface pressure between the support elements that stabilize the entire foundation. So that the support elements of adjacent ring sections abut each other in an inner area, the support elements are designed in such a way that at their origin on the stand ring or stand ring section the width of the stand ring section / 30 Λ ~ ~ - ······ · ·· :: :: · £ · **: ·:
    A ** .-- · · and the width increases continuously according to the opening angle that results from 360 ° divided by the number of ring sections of the foundation.
    Finally, and according to a preferred embodiment of the present invention, the base ring has at its end having the support elements a circumferential projection which extends radially inward from the base ring and has at least one channel provided in the projection and extending in the circumferential direction for receiving a tensioning cable. The tensioning cables in the inside projection are less favorable for exerting a tensioning force than those in the aforementioned outside projection or than those in the supporting elements due to the smaller extent, but a tensioning cable or a plurality of tensioning cables in this projection nevertheless carries a not inconsiderable amount to the overall strength of the foundation and can therefore be used to advantage in connection with the present invention.
    A further preferred embodiment of the invention provides that in the circumferential projection which extends radially inward from the standing ring at the end forming the standing surface, channels are additionally provided in the axial direction of the standing ring for receiving anchoring means for anchoring the wind power plant tower to the standing ring, in particular in the form of Anchor bolts and / or rope tension. The anchor bolts are generally provided for fastening a tower constructed as a steel structure. The rope feedthroughs are generally intended for the fastening of concrete towers.

    A ring section is preferably formed in one piece with at least one support element which extends radially outward from the ring section and has a strut rib as a prefabricated concrete element. According to this preferred embodiment of the present invention, such a prefabricated concrete element is produced by casting and is obtained directly from the casting mold. This represents a simplification of the manufacturing process compared to a process in which several concrete parts have to be put together.
    The invention is preferably further developed in such a way that a ring section comprises at least two support elements which extend radially outward from the ring section, each with a strut rib. Such a one-piece ring section of the foundation according to the invention can, for example, describe a quarter circle and have the corresponding number of support elements with primary strut ribs. If the finished foundation is to have, for example, eight support elements, an integral peripheral section of the base, which describes a quarter circle, has two support elements with two primary strut ribs.
    In order to be able to simply tension the tensioning cables when assembling the foundation according to the invention, the foundation according to the invention is preferably further developed in such a way that the channels running in the circumferential direction are made accessible to tensioning cables through recesses for receiving tensioning means. The recesses are accordingly provided in the respective structures of the ring sections which, as described above, have the channels for the tensioning cables. In the area of these recesses is / 30
    the respective channel is accessible and thus a cable can be inserted into the channel at the recesses and pushed in until the cable emerges from the channel on the other side and protrudes into the recess. The cable is then tensioned using a tensioning mechanism and the ends are fixed with a tensioning means, for example with a turnbuckle.
    According to a preferred embodiment of the present invention, the recesses for receiving tensioning means for tensioning cables are formed from recesses provided on the edge of adjacent ring sections. A recess is thus formed by two partial recesses on ring sections coming to lie adjacent in the foundation according to the invention, which is advantageous in the context of the present invention because the production of an edge recess in prefabricated concrete elements is easier to accomplish than the production of a recess that is completely enclosed by the prefabricated concrete part, as a prefabricated concrete part with an edge recess is easier to demold.
    The present invention is advantageously developed in such a way that the front standing surface has depressions for receiving wall elements of a wind power plant tower and / or for receiving an adapter for mounting a wind power plant tower. The wall elements of the wind power plant tower, which can be shaped to form towers with round or polygonal cross sections, are positively secured to the base ring with this preferred measure. If a suitable adapter is inserted into the recesses on the front / 30 :::: · ίι · : * · **:
    • · · · ·· · φ
    Stand space is used, in particular a steel tower can be erected on the adapter, the adapter additionally allowing a height adjustment to a maximum approved height of the wind power plant.
    The prefabricated concrete elements preferably consist of reinforced concrete which has a reinforcing structure, in particular reinforcing elements, profiles, rods or wires, which are embedded in the prefabricated concrete elements and / or which are designed as tensioning elements for clamping the prefabricated concrete elements into prestressed concrete elements.
    According to a preferred embodiment, the present invention is further developed in such a way that a connection structure is provided which extends in each case between opposite prefabricated concrete elements, in particular in the form of tensioning cables, in particular with the interposition of at least one circular tensioning element. Such a connection structure is intended as a supplement to the circumferential tension cables and connects opposite prefabricated concrete elements directly by radial bracing through the center of the foundation. Here, a circular clamping element in the form of a clamping plate can be interposed, on which radially extending clamping cables can be fixed and clamped. This connection structure can be formed in the area of the end of the base ring forming the base area and / or in the area of the end of the base ring having the support elements.
    In order to close the cavity at the bottom of the base ring consisting of the base ring and the mounting ring, a preferred embodiment of the present invention provides that the circumferential projection which extends radially inwards at the end of the base ring opposite the base surface has an internal step to support an Has base plate. A circular edge is thus formed, which supports a central base plate, which is arranged on the base of the base ring, circumferentially.
    According to a preferred embodiment of the present invention, the base plate has one or more
    Concrete structures for attaching auxiliary installations for the wind power plant, in particular recesses for receiving wall elements and elevations as foundations.
    The concrete used to manufacture the prefabricated concrete elements can be of any type that is typically also used for pouring concrete at the point of use. In addition to aggregates and water, concrete contains cement as a hydraulic binder.
    Fiber reinforced concrete can also be used to make the prefabricated concrete elements. The fibers can be made from any fiber material that contributes to increasing the structural integrity, particularly strength, impact resistance and / or durability, of the resulting concrete structure. Fiber reinforced concrete contains short discrete reinforcing fibers that are evenly distributed and randomly oriented.
    The reinforcing fibers are preferably carbon fibers, synthetic fibers and in particular polypropylene fibers. Alternatively, the reinforcing fibers can be steel fibers, glass 13/30
    fibers or natural fibers. The use of HPC (High Performance Concrete) and UHPC (Ultra High Performance Concrete) is also possible. These types of concrete are very fine binders with special, very fine aggregates and corresponding additives and are to be regarded as advantageous due to their relatively low weight.
    The wind turbine according to the invention with a wind turbine tower comprising a rotor is mounted on a foundation as described above and can therefore be erected quickly and inexpensively. In addition, the foundation according to the invention can be dismantled relatively easily, so that dismantling is possible with reasonable effort.
    The invention is explained in more detail below with reference to an embodiment shown in the drawing. In this show:
    1 is a perspective view of the foundation according to the invention,
    2 is a perspective view of a single ring section of the foundation according to the invention,
    Fig. 3 is a perspective view of FIG. 1 supplemented by an additional connection structure with a clamping plate and
    Fig. 4 is a perspective view of FIG. 1 supplemented by an adapter for mounting a wind turbine tower.
    In Fig. 1, the foundation according to the invention is generally designated by the reference numeral 1. The foundation 1 is made up of a number of similar prefabricated / 30: :::. 7 4 *
    Concrete elements assembled, each having a ring portion 2, which is supported by bracing ribs 3 on support elements 4. The ring sections 2 together form a base ring. In the example shown in FIG. 1, the standing ring has an annular cross section, but the cross section can also have other geometries and in particular be polygonal. Differences between the concrete elements can be seen in the area of the frontal standing area 5 for a wind power plant tower, not shown, on which depressions 6 are provided for receiving wall elements of a wind power plant tower. The prefabricated concrete elements consist of reinforced concrete, which is a reinforcement structure, in the present case in the form of prestressing elements 7 for clamping the prefabricated concrete elements into prestressed concrete elements. The tensioning elements 7 consist of tie rods which are placed under tension at the ends with screws in order to tension the concrete. In an inner area A, the support elements 4 of adjacent concrete elements lie against one another and are thus supported against one another. If the foundation is clamped together by tensioning cables, large frictional forces can be transmitted in this way, which counteract a shifting of the concrete elements against each other.
    In the illustration according to FIG. 2, it can be seen that the concrete element has at its end forming the standing surface 5 a circumferential projection 8 which extends radially outward from the ring section 2. The projection 8 is penetrated by a plurality of channels 9 for receiving tensioning cables which, in the assembled state of the foundation, form a circumferential cable channel in which a tensioning cable can extend to a relatively large extent around the central ring in order to tension the concrete elements together. With 10 is an edge recess for receiving tensioning means, not shown, for tensioning cables, which in the present case makes three channels 9 accessible for receiving tensioning cables. The three channels 9 lead to the bottom of the recess 10 in the body of the projection 8 on the bottom of FIG do. Further channels 9 ', 9''and9''' are provided in the projection 8 'extending inwards from the end forming the base and in the projection 8 , z extending radially inwards from the end having the support elements, and in the support element 4, to take up tensioning cables so that the foundation can be assembled from the ring sections 2 made of prefabricated concrete elements without screwing. For the same purpose, the ring section 2 has further channels 9 ''''.
    In Fig. 3, the same parts are provided with the same reference numerals and it can be seen that an additional connection structure in the form of tensioning cables 11 is provided, which connect opposing prefabricated concrete elements of the foundation 1 to one another by means of tensioning cables 12 running in the radial direction. The tensioning cables 12 extend with the interposition of a circular tensioning element or tensioning plate 13 between opposite prefabricated concrete elements of the foundation 1 and can be fixed and tensioned thereon. A similar connection structure can be found in / 30
    Area of the end of the base ring having the support elements 4 may be provided.
    In Fig. 4, the same parts are again provided with the same reference numerals and it can be seen that an adapter 14 for the assembly of a wind power plant tower with suitable wall elements 14 'can be accommodated in the recesses 6 of the end face 5. With such an adapter 14, for example, a steel tower can also be mounted particularly simply on the foundation 1 according to the invention. In addition, the adapter 14 can be manufactured in different heights in order to allow the height of the wind power plant to be adapted to a maximum approved height if corresponding masts are only available in a few, roughly graduated height variants.
