Definitions
- the present invention relates to a vertical support structure or tower for wind turbines of electric power or other uses, in prestressed concrete, which provides a prestressed concrete shaft of variable conical or cylindrical height made by annular sectors, each of which comprises several pieces of wall semicircular or polygonal section or circular or polygonal sectors, joined together longitudinally, and in case of several overlays in height, joined transversely with a system that allows the structural continuity of the tower.
- the wind turbine or another metal shaft on which the generator will finally be fixed will be located at its upper end.
- This invention has its application within the field of construction in general and especially within the industry intended for the construction and installation of support structures for wind turbines.
- a second aspect of the invention concerns a method for erecting the support structure or tower from the successive incorporation of said wall pieces
- a wall piece will be understood as a forming part of the wall of the support structure or tower, said thin wall being 5 to 30 cm in prestressed concrete, with a centered prestressing and passive reinforcement in the perimeter of the section or concrete reinforced with fibers, suitable to form an annular sector of the support structure or tower together with one or more pieces.
- US 580971 1 discloses an apparatus and a method for joining two precompressed concrete elements capable of forming structures such as masts, towers or for example bridges.
- the patent describes some prestressed concrete elements on a bench, in the form of wall pieces, with several prestressing cables that are extended protruding outside the wall piece, and which are arranged inserted through conduits configured in a piece of adjacent wall, superimposed, which conduits affect said adjacent part in its entirety, for linking to it by a subsequent testing of said extension cables, obtaining transverse joints.
- the present invention proposes a vertical support structure or tower, of the type comprising several overlapping annular structural sections, each of which integrates two or more wall pieces joined by their longitudinal edges, and it differs from the previous proposals, which are generally based on the post-tensioning of cables at the installation point of the tower or wind farm, to provide resistance to the tower and the joints, for the particularity of carrying out
- the wall pieces by prestressing in the workshop calculated according to the relative position that the piece will occupy in the tower or structure, so that the constituent parts of the tower, when the prestressing is incorporated, are already structurally resistant, requiring only the realization of the joints between adjacent and overlapping wall pieces to form the tower.
- the applied technology eliminates the need for auxiliary elements for transport, guarantees a state of compression in the pieces that maximizes the useful life of the tower, allows new designs and mounting alternatives that simplify the obtaining of the tower.
- connection system between prefabricated elements with prestressed reinforcement, in particular applicable to the union of the annular sectors of the shaft, which allows the continuity of the prestressing action without need (total or partial) of additional elements such as tie rods or other post-tensioning systems, and compressing the extreme areas of each piece in which the loss of prestressing by diffusion occurs in the joints, taking advantage of their own prestressing cables that configure the reinforcement active of the prestressed wall pieces mentioned, but that unlike the solution explained in US 580971 1, only affects a short sector of each piece, end, in the areas of union of the overlapping pieces.
- the present invention solves the prefabrication of the tower by means of large pieces of concrete wall prestressed in the manufacturing bench (controlled application of a tension to the concrete by testing of tendons or steel cables), of length limited exclusively by transport conditions (with typical lengths of 20 to 40 m), with semicircular section or circular sector, or polygonal or polygonal sector, each piece being designed to work subject to the stresses derived from its own weight and transport as if it were a large beam with a U-section of predetermined structural resistance.
- each of the pieces in origin has been calculated for each piece of wall according to the relative position that said piece of wall must occupy in the support structure, or tower, that is to say to respond adequately to the requirements of structural load in each of the sections of the tower.
- these wall pieces allow the support or tower structure to be formed without the need to subject the whole of each piece to additional, subsequent work posts, affecting the entire piece.
- each piece of wall typically lengths of 1 to 1, 5m
- the support structure or tower that is proposed integrates a truncated cone in general, although it can be cylindrical, partially formed by two or more overlapping annular sectors or structural sections, joined together by transverse joints.
- each annular structural section of the tower integrates two or more prefabricated and prestressed wall pieces in the workshop, according to the aforementioned, joined by its sides forming longitudinal joints of the tower.
- the prestressing can be with post-tensioned reinforcements, in which the concreting is carried out before the testing of the active reinforcements, staying in ducts or sheaths proceeding to the testing and anchoring of those when the concrete has acquired sufficient strength, or, as it concerns here , with 10 prestressed reinforcements, in which the concreting is carried out after having tested and provisionally anchored the reinforcements in fixed elements.
- the reinforcements of its provisional anchors are released and, by adhesion, the force previously introduced in the reinforcements is transferred to the concrete.
- the tendon from the point of view of the adhesion conditions, can be adherent, as is the case of prestressing with prestressed reinforcement, or with post-tensioned reinforcement in which, after tensioning, adherent material is injected between the reinforcement and the concrete, or non-adherent, as is the case of prestressing with post-tension reinforcement in which reinforcement protection systems are used that do not create adhesion.
- this first cone trunk it will be located, until reaching the necessary height, or a new stretch of prestressed concrete formed again by two semicircular pieces, or a metal section.
- Each piece will be composed of a semicircular or polygonal section or sector thereof, of small thickness and variable radius, in high-strength concrete that can be if self-compacting, high-strength concrete, or concrete with fibers with a centered prestressing is required. or slightly offset to correct the effects of the own weight or other temporary loads, and a reinforcement that can be by adding fibers to the concrete or with passive reinforcement in the perimeter of the section, which will be executed horizontally in a mold and benches Prepared for this purpose.
- the mold part guarantees the maintenance without cracking of the entire concrete section, preserving the mechanical and durability characteristics of the tower. This aspect is of vital importance since in other reinforced concrete solutions it deforms under the stresses and the steel to start working needs to stretch producing cracks in concrete. In the prestressed part from the same manufacturing process, the non-appearance of cracks is guaranteed, increasing the useful life of the tower and eliminating the need for maintenance that is very expensive in other solutions.
- the wall piece instead of being manufactured by prestressing could also be obtained by a post-tensioning in the workshop (regardless of the complexity and costs of
- the manipulation and transport of the wall pieces, until their definitive positioning, will be carried out in the manufacturing position, being possible, given the slenderness of the element, certain elements of transverse dragging.
- the longitudinal joints (according to the generatrix of the cone trunk) between the pieces will be made by a wet joint, with the overlapping and threading of a passive reinforcement and a subsequent filling with a high-strength mortar, or by means of a dry joint, either by means of bushings and bolts inside the wall of the piece crossed diagonally on the floor and at different heights, or with perforated concrete flanges, at along the inside of the longitudinal edges of the piece, which would allow sewing of the joint by means of threaded bolts and nuts, with control of the tightening torque.
- the vertical joints can be rotated, in plan in order to avoid a continuous joint along the different shaft sections, or not rotate and leave a continuous longitudinal joint, as appropriate .
- transverse joints between sections, or between the first section and the foundation will be made by a widening at the ends of the piece drilled in the direction of the generatrix of the piece that allows sewing by means of high-strength steel bars that can sew
- the joint by means of a wet joint anchored by an overlap, a screwed joint or a post-tensioned joint at the time of assembly, which will be protected with liquid or plastic mortars of cement and / or resins, as well as any other protective products such as waxes.
- these joint bars in addition to sewing both pieces, guarantee the continuity of the prestressing in all sections of the tower.
- different lengths of thickening and sewing will be necessary, and can be used, in case of anchoring of the prestressing from the end of the piece or in the case of post-tensioning the thickening of the concrete section at the ends of the piece, a thick metal sheet in the form of an inner flange at said end may be replaced by location, which allows, thanks to the perforations pertinent, the union to the rest of elements by means of bars of high resistance that will be screwed with tightening torque control or will be post-tensioned.
- these waiting bars may have been placed at the time of execution of the shoe or later by positioning the foundation sheaths in which the bars are introduced prior to filling with high-strength mortar.
- each section of the tower can be made up of two semicircular or polygonal pieces, but also for more pieces of section of semicircular or polygonal sector, that is, four pieces of half section, six pieces of third section, eight pieces of quarter section, etc., it should be noted that said pieces, at the start of foundation of the tower they can have a different length, for example half of them have a normal length and the other half, in an interleaved way, have half of said length, so that in the successive overlaps of the following sections, the transverse joints remain at different levels , being half of the pieces that culminate the tower, again half the length to be all flush.
- This assembly system avoids the use of auxiliary towers reducing assembly times and costs.
- the exterior and interior concrete finish of the pieces may be any of those existing for other types of pieces, such as smooth, painted, textured, washed, etc.
- the pieces may present the necessary gaps for access to the interior of the tower of people and equipment.
- the assembly system may require the prior assembly of an auxiliary tower, which, once the work is finished, can be disassembled or not, remaining inside the tower.
- the invention also proposes a connection system of prefabricated pre-fabricated elements from the prestressing cables themselves, which offers the possibility of connection between prefabricated elements with pre-assembled armor without the need for additional elements from the post-testing. of a part of the tester cables of the wall piece
- the prestressing cables used are extended by sections that protrude outside the wall piece, said extension sections being provided for their arrangement inserted through conduits configured in an adjacent wall piece, for linking to it by a subsequent testing of said cable extension sections, by having two overlapping wall pieces facing each other, obtaining a transverse joint that guarantees the continuity of the prestressing
- the protruding part outside the cables (which, in any case, is necessary for testing and which, however, in the conventional solution intended then must be cut), is it houses in ducts left for this purpose in the adjacent piece, which can all be located on the same side of the joint, or combined on either side.
- the system of the invention provides for the use of elements with longitudinal grooves and even common anchor plates with said typology.
- This new system and process of retension allows to give continuity to the action of prestressing, requiring only a thickening of the cross section of the piece in a length of between 50 and 300 cm, for the accommodation of the anchoring elements.
- the system is non-adherent in the area of the joint, given the need for subsequent testing by one part and the breakage of the adhesion of the concrete at the end, on the other.
- test cable can be protected simply with grease or wax, or alternatively, a subsequent injection of the resin or cement slurry connection system to provide an adherent system.
- anchors protection elements such as caps or the like are viable.
- the wedge penetration must be small, requiring precise calculations to determine the amount of testing to be performed, as well as the necessary dimensions of the anchorage areas.
- the prestressing cable will be the usual one for conventional prestressing reinforcements, 0.5, 0.6, or 0.62 inches or others.
- this invention in addition to fully resolving the technical needs generated in the wind sector for new generation wind turbines, allows to improve the cost expectations of the towers, offering additional advantages such as low maintenance or the possibility of disassembly and transfer of the tower in case of dry joints, the greater durability or the greater resistance to fatigue.

- both the longitudinal joints -6- and the transverse joints -7- may be provided with a conventional guidance system -18 - as detailed in Fig. 17.
- the pieces will be optionally equipped with a transverse bracing system -19- as shown in Fig. 18.
- each section or shaft -1 of the tower can be formed by more than two pieces -2- and -3- of section of semicircular or polygonal sector, (six pieces of third of section in the example shown) half of which, at the start of the foundation of the tower and intercalated, have a normal length -2- and the others -3- approximately half, so that, in successive overlays of the sections -1 - following, the longitudinal joints -6- are not rotated and the transverse ones -7- are at different levels, being half of the pieces that culminate the tower, again half the length to be all flush on the cusp.
- connection system between prefabricated prefabricated elements which is proposed is embodied in this exemplary embodiment, starting from prefabricated wall pieces -2-, such as those referred to this point, provided inside of some pre-tensioned tendons or cables with a portion of the cable -4a- that protrudes outside housed in conduits -24- provided for that purpose in the adjacent wall piece -2- to which it must be attached.
- a greasing -21- of its cross-section suitable for the accommodation of the anchoring elements -22- on which protection elements -23- such as protection elements -23- can be incorporated such as Hoods or similar.
- Said ducts -24 may all be located on the same side of the joint as observed in the example shown in Fig. 3, or combined on either side, as shown in the example of the figure 4.
- the system of the invention provides for the use of elements with longitudinal grooves and even common anchor plates with said typology (not shown).
- the system is non-adherent in the area of the greasing 21 - in which the ducts -4a- are located, given the need for post-testing of one part and of the breakage of the adhesion of the concrete at the end, on the other, but nevertheless, the test cable can be protected simply with grease or wax, or alternatively, a subsequent injection of the connection system with resin or cement slurry is performed to provide an adherent system.
- FIG. 22 an Example of an implementable methodology to erect the support structure or tower according to the invention is shown, appreciating how each of the pieces of pairs (2, 3) is installed separately joining, if necessary, a piece adjacent through a longitudinal joint (union of the interconnected, vertical contact edges or forming a transverse joint joining a piece (2, 3) to the immediate lower one.
- the implementation of the invention is compatible with the realization of a local post-installation in certain parts of the tower that require greater demands or with a post-tensioning that affects only some of the wall pieces or part thereof, in the good understood that the majority of the wall pieces will depend on the structural rigidity obtained in their manufacture in bank.
