    Wind tower pedestal. Pedestal (1) of wind tower that is installed between a foundation and a steel wind tower previously designed to increase the height of the wind tower without changing its design. It is arranged above ground level and allows the dynamic characteristics of the system to be adjusted so that the dynamic load regime calculated for existing metal towers does not change. It comprises a shaft (2) with a plurality of horizontal structural elements (3) joined together forming horizontal divisions and dynamic modulators (6) joined at one end to the upper base surface (4) or to a horizontal structural element (3) of the stem and at the other end are joined to the lower base surface (5) or to the foundation. These dynamic modulators are configured to adjust the dynamic properties of the system to the requirements of the project. (Machine-translation by Google Translate, not legally binding)

    top base of the shaft with heavy duty bars.
    In the exemplary embodiment in which the dynamic modulators are attached to a horizontal structural element of the shaft that does not correspond to the upper base surface, there are always post-tensioned reinforcing cables that extend vertically from the upper base surface (in the union with the tower) to the horizontal structural element to which the dynamic modulators are attached. This condition is necessary for the correct transfer of the dynamic forces of the metallic wind tower through the pedestal. That is, it is essential that the shaft is compressed between the tower connection and the start of the reinforcement cables in the foundation.
    This is why in the described pedestal the post-tensioning starts above or at the level of the tower connection, as previously explained. In this way the non-decompression condition is met under hypotheses dictated by calculation code.
    The horizontal structural elements that make up the shaft, as well as the horizontal bypass structural element, can be solid, hollow elements or with internal radial reinforcements to stiffen the section.
    In the exemplary embodiment in which the dynamic modulators are attached to the bottom base surface of the shaft, this connection is made by means of lower anchors, which can be, for example, delta wedges. Said wedges are arranged on the lower base surface and dynamic modulators are supported therein. The reinforcement cables inside are attached to the lower base surface through the inside of the wedges.
    The horizontal structural elements are bonded to each other with dry divisions. In embodiments where it is necessary to reinforce said divisions, the possibility of reinforcing them with mortar is contemplated. These horizontal structural elements, which can be cylindrical or polygonal, are as high as the load of the cranes allows, minimizing the number of horizontal divisions, limiting their slenderness to forty times their thickness. The key to ensuring dry horizontal divisions are the post-tensioned reinforcement cables that keep them compressed at all times during the life of the pedestal.

    Examples of embodiments of the present invention are described below with the aid of Figures 1 to 10.
    The wind tower pedestal of the present invention is configured to be installed between a foundation and a metal wind tower already designed without modifying its design. The pedestal (1) is arranged on the ground and is not buried or partially buried in it but arranged on a foundation or a

    Horizontal (3) have flat faces allows to adjust more easily the dynamic modulators (6).
    Figure 6 shows a horizontal division (9) that is the area of union between horizontal structural elements (3) of the shaft. The division (9) is designed to serve as a barrier to the entry of water from the outside of the pedestal (1), to function as a shear key between the horizontal structural elements (3), and to, in case of emergency, to execute wet joint It is a joint with trough breast and internal inclined pour cannulas for injection of the filling mortar.
    In this case the upper face (10) of each horizontal structural element (3) comprises at least one recess (12) and the lower face (11) comprises a shoulder (13). In an exemplary embodiment, these are recesses (12) and projections (13) that extend along the entire section and in all cases the recesses (12) and the projections (13) are complementary. Thus, when a horizontal structural element (3) is placed on an equal horizontal structural element (3), the at least one shoulder (13) of the lower face (11) is housed in the at least one recess (12) of the upper face (10).
    This type of divisions (9) for dry joints are also applicable to the horizontal division between the horizontal structural deviation element (14) and the horizontal structural element (3) of the shaft to which it is attached in the embodiments in the that the shaft comprises said horizontal deflection structural element.
    In the exemplary embodiment in which the shaft (2) comprises at least one horizontal deflection structural element (14), it is arranged in contact with at least one of the horizontal structural elements (3) of the shaft (2). In the event that the dynamic modulators (6) do not extend to the upper base surface (4), they extend to said horizontal structural diverting element (14) in which the change of trajectory of the reinforcement cable (of trajectory) is made vertical from the upper base surface (4) to the horizontal deflection structural element (14) with an inclined path along the dynamic modulator (6)).
    As can be seen in Figures 7a-b and 8a-b, the change of trajectory of the cables

    reinforcement (7) can be performed directly inside the horizontal bypass structural element (14) (or the upper base surface (4) if the dynamic modulator (6) extends directly from it) or the same effect can be obtained using two reinforcement cables (7). In this second example, one of the reinforcing cables (7) is
    5 extends vertically between the upper base surface (4), to which it is anchored, and the horizontal structural deflection element (14), to which it is anchored, and another horizontal part cable extends the horizontal structural deflection element (14) , to which it is anchored, with the corresponding inclination through the dynamic modulator (6).
    10 For high-rise pedestals, the preferred option will be the continuous reinforcement cable (shown in Figure 7a) because the angle of breakage is light. For small pedestals, the solution of several reinforcement cables (7) connected to the horizontal bypass structural element (14) (shown in Figure 7a) will preferably be carried out.
    15 Figures 9a and 9b represent two alternatives to the connection between metallic wind tower (8), and pedestal (1). In the embodiment of figure 9a, the reinforcement cables (7) of the pedestal (1) go inside the section of the wind tower (8), and in the embodiment of figure 9b, the reinforcement cables (7) They go outside the wind tower (8). The choice of one embodiment or another depends on the diameter of the metallic wind tower. In
    In general, the reinforcement cables (7) are arranged inside the wind tower (8), but in the case of very narrow towers, said cables are arranged outside.
    Figure 10 shows a lower anchor (15) that can be arranged at the lower end of the dynamic modulators (6) and configured to join for
    25 join the lower base surface (5) or the foundation. It is a delta-shaped reinforced concrete element that is configured to connect the dynamic modulators (6) to the foundation and to pass the reinforcement cable (7) that runs through the dynamic modulator (6) to the foundation. Said lower anchor (15) also comprises registration for the testing mechanism.
