    -The prestressed steel bars 5 have to be placed one by one with
    the difficulties that this entails taking into account the height situation of the
    Concrete section 11. The tower assembly process is therefore slowed down.
    -A platform is required to access the anchor plates 7
    5 of prestressed steel bars 5.
    -Maximum tolerances for the correct positioning of the bars
    Prestressed steel 5 are large. Relative displacements may occur
    between the ducts during concreting.
    -In the case of on-site concrete towers, the assembly process is
    10 severely penalized.
    In another variant of the solution mentioned above the plates of
    anchor 7 are embedded by the concrete of the widened area 13. Among its
    drawbacks include the following:
    -It is more difficult to ensure the correct positioning of the bars
    fifteen prestressed steel 5. Relative displacements can occur between them
    during concreting.
    -In the case of on-site concrete towers, the assembly process is
    severely penalized.
    The present invention is focused on the solution of those
    2 o inconvenience
    SUMMARY OF THE INVENTION
    In a first aspect, the invention provides a joining device for
    25 a metal section to a concrete section of a hollow tower in which the
    second has a widened area with reinforcement reinforcement to serve as
    support base of the first. The joining device is formed by a set of
    bolts through one of its ends through holes in an anchor ring and
    fixed on both sides of it by a first set of nuts and arranged
    3 o to join at its base to the base of the metal section by means of a
    Second set of nuts. The anchor ring includes a set of
    connectors that extend externally and internally to it in a
    direction substantially perpendicular to the bolts and are disposed of
    so that they do not interfere with reinforcement reinforcements. The joining device
    it is embedded in the widened area of the concrete section, except for
    ends of the bolts intended to join the metal section. That device
    5 provides a very efficient anchor structure for bolts since
    allows to use an anchor ring of reduced width which facilitates its
    installation in the concrete section by providing said connectors a
    additional surface of contact with the concrete to transmit by adhesion
    the efforts received by bolts.
    10 The joining device of the invention is especially advantageous.
    when the metal section and the concrete section are cylindrical and / or
    conical trunk The anchor ring has a circular shape, the bolts are located
    at the same distance from the center of the anchor ring and the bars are
    arranged in radial direction.
    fifteen In one embodiment, the anchor ring has a cross section
    rectangular and said connectors are attached to the side surfaces of the ring
    anchoring and arranged alternately at different distances from their
    upper edges.
    Advantageously, the anchor ring connectors are configured
    2 o with a protruding end to increase its ability to adhere to
    concrete.
    In a second aspect, the invention provides a hollow tower that
    it comprises at least one metal section attached to a concrete section by
    The mentioned joining device.
    25 Other desirable features and advantages of the invention will be made.
    evident from the following detailed description and claims
    attached in relation to the accompanying figures.

    2 o Detailed description of the invention
    The present invention proposes the use of a bolt cage
    as a device for joining a metal section to a concrete section of a
    hollow tower of the type used to support wind turbines in which
    25 said sections have a cylindrical and / or truncated cone shape.
    In joining a metal tower 16 to a foundation it is well known
    the use of a bolt cage (see Figures 2a and 2b) formed by a
    set of bolts 22 attached to an anchor ring 24 by nuts 34
    arranged on both sides of it. The bolt set 22 is arranged
    3O in said anchor ring 24 following the traces of two circumferences
    concentric and at a predetermined distance between them.
    That bolt cage is installed in the foundation hole of the tower
    metal 16 leaving the free ends of the bolts 22 protruding from the
    ground plane 12 so that they can serve as a means of connection with the
    base 14 of metal tower 16 after applying nuts 36. In one stage
    5 Afterwards, the foundation is concreted, leaving the cage
    of bolts embedded in concrete.
    With that structuring, the bolts 22 transmit both the forces of
    prestressed as those trying to open / decompress the steel / concrete joint to
    the foundation by means of the anchor ring 24.
    10 In the case of hybrid towers, the solution of the bolt cage is
    potentially interesting for joining a metal section 15 with a base
    17 to a concrete section 11 with a widened area 13 at its edge in
    contact with the metal section 15. A direct application of it (see
    Figures 3a and 3b) show that:
    fifteen -In the area where the anchor ring 24 should be located there is a
    large amount of reinforcement reinforcement 19 of the widened area 23.
    -The anchor ring 24 necessary to transmit the cage stresses
    from bolts to concrete is too big.
    -The free space available in the widened area 23 is limited given the
    twenty need for continuity of reinforcement reinforcement 19.
    As a consequence of all this, there is a high probability of
    interference between anchor ring 24 and reinforcement reinforcements 19 which
    make the applicability of the bolt cage unfeasible by hindering the correct
    positioning of reinforcement reinforcement 19.
    25 To solve this problem, we propose (see Figures 4a-4e) a
    Bolt cage-shaped joint device. Bolt set 23 is
    arranged in an anchor ring 25 following the trace of a circle and to
    a preset distance between them. They are fixed to anchor ring 25 by
    nuts 33. The joining device additionally comprises a set of
    3O connectors 29 arranged radially on both sides of the anchor ring
    25 which complement the anchor ring 25 as transmission means of
    efforts to the concrete by adhesion. Connectors 29 are configured
    preferably with a protruding end to improve its ability to adhere to concrete. The free ends of the bolts 23 are fixed to the base 17 of the metal section 15 by nuts 35.
    With this configuration the width of the anchor ring 25 is reduced
    5 thereby avoiding interference with the reinforcement reinforcements 19. For its part, the reduced width of the anchor ring 25 facilitates the space necessary for the bolts 23 to pass through it so that adjustment between the shapes of the section is facilitated of concrete 11 and metal section 15.
    In the preferred embodiment illustrated in the Figures the anchor ring 25
    10 has a rectangular cross-section and the connectors 29 are alternately arranged at different distances from the upper edges to facilitate compatibility with the reinforcement reinforcements 19. Although the present invention has been described in relation to various embodiments, it will be appreciated from the description that can be made
    Various combinations of elements, variations or improvements therein, and are within the scope of the invention as defined in the appended claims.
