    The concrete tower comprises: a shaft (1) and a foundation (2). The shaft (1) is formed by two differentiated sections: - an upper section (11) comprised between an intermediate section (13) and an upper section (14) of the shaft (1); arranging said upper section (11) of internal tendons (3) of post-tensioning, tensioned between the intermediate section (13) and the upper section (14); and - a lower section (12) of concrete comprised between the intermediate section (13) and a foundation (2); providing said lower section (12) of outer tendons (4) of post-tensioning and bracing, which diverge towards the lower area and which are fixed by ends opposite the intermediate section (13) of the shaft (1) and the foundation ( 2) of said lower section. The foundation (2) comprises a concrete ring (21) provided with radial ribs (22) of variable edge. (Machine-translation by Google Translate, not legally binding)

    Understanding the characteristics of the invention, a set of drawings is attached to the present specification in which, as an illustration and not limitation, the following has been represented:
    -  Figure 1 shows a perspective view of an embodiment of the concrete tower of the invention.
    -  Figure 2 shows a schematic perspective view of an embodiment example of the concrete tower according to the invention in a position of use supporting a wind generator.
    -  Figure 3 corresponds to a top plan view of the tower of Figure 2 supporting a wind turbine.
    -  Figure 4 shows an elevation view of the concrete tower according to the invention sectioned by a vertical plane and in which the inner tendons of the upper section of the shaft and the outer tendons of the lower section thereof can be seen.
    -  Figure 5 shows a perspective detail of an upper portion of the tower sectioned by a vertical plane, in which it is possible to observe the fixation of the inner tendons and the outer tendons to the shaft of the concrete tower.
    -  Figure 6 shows a perspective detail of a lower portion of the concrete tower in which the foundation and the fixation of the outer tendons to said foundation can be observed.
    -  Figure 7 shows a perspective view of a lower portion of the tower, in which the ribs of the foundation comprise ground tendons.
    -  Figure 8 shows a perspective view of the lower portion of the tower of Figure 7, sectioned by a vertical plane, in which the ribs of the foundation internally comprise post-tensioning tendons
    Preferred embodiment of the invention.

    Figure 1 shows an example of an embodiment of the concrete tower according to the invention, comprising: a shaft (1) formed by a hollow concrete cylinder "in situ" post-tensioned, of constant outside diameter, and a foundation ( 2) ground fixing.
    In figures 2 and 3 the concrete tower of figure 1 can be seen, in use position supporting a wind turbine (A) mounted on the tower in question.
    As can be seen in Figure 4, the shaft (1) comprises an upper section (11) comprised between a reinforced intermediate section (13) and a reinforced section (14), constituted by an increase in thickness of the shaft (1) ) of concrete; and a lower section (12) between the intermediate section (13) and a foundation (2) arranged at its lower end.
    In figures 5 and 6 the upper section (11) has internally oriented post-tensioning tendons (3) and arranged with a circular distribution inside said upper section (11), said inner tendons being tensioned between an intermediate section (13) reinforced and an upper section (14) also reinforced, constituted by an increase in thickness of the concrete shaft (1), as can be seen more clearly in Figure 4.
    The mentioned interior tendons (3) establish the post-tensioning of the concrete forming the upper section (11) of the shaft (1) of the tower.
    The lower section (12) of the shaft is provided with external tendons (4) for post-tensioning and bracing of the tower, fixed at its ends to the reinforced intermediate section (13) of the shaft and to the foundation (2), specifically to the end of radial ribs (22) that start from a concrete ring (21) and that together with said concrete ring constitute the foundation (2).
    In the embodiment shown in Figures 7 and 8 the radial ribs (22) of the foundation (2) incorporate post-tensioning tendons (23) oriented in the radial direction, to absorb the
    8
    tractions that introduce the outer tendons (4) of the tower into said radial ribs (22).
    In the section shown in Figure 8, the radial ribs (22) of the foundation (2) have 5 tendons (5) anchored to the ground at their end.
    Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated to the appropriate effects that the materials, shape, size and arrangement of the described elements may be modified, provided
    10 does not imply an alteration of the essential features of the invention that are claimed below.
