    CONCRETE TOWER AND TREPANT OR SELF-TREWING FORMWORK DEVICE FOR CONSTRUCTION “IN SITU”.
    Object of the invention.
    The object of this invention is a concrete tower and a climbing or self-climbing formwork device for its construction "in situ".
    The tower in question, made with the formwork device, has a hollow concrete body of variable section in vertical direction; with the particularity that the formwork of each tower section totally coincides with the formwork of the immediately lower section of the tower, built previously, varying only in each immediate upper section of formwork the number of parts used in the configuration of the lower section, providing a variable and changing geometry tower from a lower polygonal section (which combines flat surfaces and curved surfaces) to an exclusively curved section at the top end of the tower.
    Field of application of the invention.
    This invention is applicable in the construction of concrete towers and, preferably, but not limited to, towers for the installation of wind turbines, which require in their upper part a circular section where the wind turbine is coupled by means of a transition piece.
    State of the art.
    In the construction of concrete towers of variable section, conical towers, for example, the use of different formwork panels is needed to cover the entire tower to be built and subsequently pour the concrete, leaving the tower with this shape. But at great heights what is done is to make the construction through successive sections; the formwork of a section is made, the concrete is poured, and a second section is formed, forcing to change in

    each climbs the curvature of the formwork, expensive operation, and repeating this process until the height of the tower is finished.
    There are adjustable formwork panels on the market that allow you to adjust your curvature before assembling and fixing; However, this adjustment is very complicated, especially when one of the panels has undergone some deformation.
    From the same applicant is the national patent ES2 404 781 which shows a construction system and method of a concrete tower as well as the tower obtained. That reinforced or prestressed concrete tower is divided into several faces, number of faces that can be variable, said faces being curved, from the base to the highest height; For example, you can present a square base with curved faces to finish the section of the top of the tower with the same four faces with curved faces but smaller section.
    To build the successive sections of that tower, it also uses the climbing technique that consists of uninstalling the formwork panels of lower heights and installing them in an immediately superior position to form the formwork of this new level and build a new section.
    The problem in that tower is the corners that have a variable angle with the height which implies a small clearance between the annexed faces of the formwork, as the faces are formed by the intersection of "n" cylindrical surfaces that define "N" faces of The concrete tower. Clearance that in a concrete tower can be absorbed while maintaining the functionality of the structure.
    Another background is the international file of VESTAS WIND SYSTEMS, WO 2004/083633, which details a method of construction of wind turbine towers. The tower is created in that patent by sections that are configured by the union of two or three curved plates; each section is reducing its section until completing a conical shaped tower. It differs from the patent presented because it is a metal structure of prefabricated pieces. For the construction of a tower that is configured by joining the pieces created at the factory and assembled on site. This background has the disadvantage of

    having to solve the constant problem of assembling the pieces by generating both vertical and horizontal joints, as they are prefabricated parts.
    Description of the invention.
    The present invention refers to a concrete tower made "in situ" and a formwork device suitable for the formation of successive sections of formwork applicable in the construction by sections or sections of said tower with reinforced concrete or post-tensioned concrete by means of the climbing technique or self-climbing. This invention has features aimed at solving the exposed problem and avoiding the existence of gaps between the attached faces of the formwork, and to provide a uniform surface on the entire exterior surface of the concrete tower.
    This tower of the invention, being performed "in situ", does not present any type of joint that needs to be treated. Proceeding to pour new concrete on the previous toned.
    According to the invention, this concrete tower comprises at a lower end a polygonal general configuration, constituted by flat faces and cylindrical portions arranged between consecutive flat faces, the flat faces presenting a decreasing width in ascending direction along The tower and the cylindrical portions invariably form along the tower.
    The aforementioned flat faces have a decreasing width upwards, from a maximum width corresponding to the lower end of the tower to a null width at the upper end of the tower; the tower at said upper end presenting a circular contour, constituted by the cylindrical portions that maintain an invariable shape along the tower.
    With these characteristics, the concrete tower changes its contour in a vertical direction, starting inferiorly in a polygonal shape with its circular vertices and with an upper end of a circular contour.

    For the construction of this concrete tower by sections, through the technique of climbing or self-climbing, a climbing formwork device has been developed, which allows the formwork of successive tower sections to be formed by utilizing the parts that compose it, Only the number of pieces used in the configuration of the lower section vary on each immediate upper form section, removing one or several flat pieces on each side, or creating an equivalent overlap.
    This climbing formwork device comprises: - corner formwork pieces for the definition of the cylindrical portions of the tower; whose corner pieces have: an upper end and a lower end that define two parallel planes, a longitudinally oriented curved area along said corner pieces, said curved area having a constant radius of curvature and a straight generatrix with a predetermined inclination with respect to the parallel planes defined by the upper and lower ends of said corner pieces; and - intermediate rectangular pieces, which are arranged laterally attached between the corner pieces and with the same inclination as the generatrix of the corner pieces, said rectangular pieces defining, in successive sections of formwork, flat surfaces corresponding to the flat faces of the tower.
    In a first embodiment, the corner pieces of the formwork have flat appendages on the opposite sides of the curved area, of triangular-rectangular configuration, each of said flat appendages has a base and a height of dimensions coinciding respectively with half of the base and with the height of the rectangular pieces, which must be removed in each climb.
    These flat appendages, of triangular - rectangular configuration, define in the successive sections or climbs of the formwork a splice area between the rounded corner pieces and the intermediate rectangular pieces.
    In a variant embodiment of the formwork described above, the corner pieces of the formwork have a constant width in the direction of the generatrix; that is, they lack flat extensions of rectangular prismatic configuration on their sides; which allows said corner pieces to be displaced, without gaps, and in the direction of the generatrix to define

    in the successive formwork sections the cylindrical portions that extend along the tower and are arranged between the flat faces, which have a decreasing width in ascending direction.
    In this variant of realization the formwork additionally comprises flat pieces of triangular-rectangular configuration, which have a base and a height of dimensions coinciding respectively with half of the base and with the height of the rectangular pieces, and which are arranged one to each side of the curved corner pieces in the formwork of each tower section.
    This system allows to create multi-sided towers; in the case of four faces, four circular pieces (a quarter of a circumference) that form the corners of the formwork of this polygonal shape are arranged at the base. Between each curved area the flat pieces are arranged, which are the ones that will be removed, at least one of them on each side, in the conformation of the next section.
    Another constructive advantage is that it is ideal for the formwork technique with a self-climbing system, without the need to use cranes, which consists in raising the next level of formwork starting from the previous one we have set. For this, rails or glues are placed where the self-climbing system ascends, consisting of a platform that moves through the glues (two or three on each of the cylindrical faces of the tower) driven by a hydraulic drive and / or mechanic.
    This self-climbing system is very simple for the construction of the tower of the invention, since the curved areas of the tower are used to place the two or three glues of the self-climbing system, following the generatrices of the cylinder that forms the corners , totally straight in the entire tower under construction, which allows to accelerate the work processes on site.
    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:

    - Figure 8 shows a variant embodiment of the formwork shown in Figure 3, suitable for the construction of three-sided towers, representing the last three sections of formwork for the construction of a triangular tower.
    Preferred embodiment of the invention.
    As can be seen in Figure 1, the concrete tower referenced as a whole as (1) comprises a hollow concrete body, of variable section in vertical direction, said tower having a lower end (11) with a polygonal configuration constituted by flat faces (12) and cylindrical portions (13) arranged between consecutive flat faces (12).
    The flat faces (12) of the tower have a decreasing width upward along the tower until reaching an upper end (14) in which
    5
    10

    25

    35
    the flat faces (12) have a null width; and the cylindrical portions (13), invariably and radius of constant curvature along the entire tower, converge with each other providing said upper end (14) a circular contour.
    In the example of realization shown in Figures 3 and 4, a formwork device comprising corner pieces (2a) of formwork can be observed for the definition of the cylindrical portions (13) of the tower (1) and intermediate rectangular pieces (3) of a height equal to that of the corner pieces (2a).
    Said corner pieces (2a) have an upper end (21) and a lower end (22) that define two parallel and horizontal planes in the position of use of the formwork; said corner pieces (2a) also having a longitudinally oriented curved area (23) and two flat appendages (24) of triangular-rectangular configuration arranged on opposite sides of the curved area (23).
    Said curved zone (23) has a constant radius of curvature and a straight generatrix with a predetermined inclination with respect to the parallel planes defined by the upper and lower ends (21, 22) of said corner pieces. The inclination of said generatrix is what defines the inclination in the tower (1) of the cylindrical portions (13).
    The flat appendages (24) defined on opposite sides of the corner pieces (2a) have a base and a height of dimensions coinciding with half the base and height of the rectangular pieces (3), being arranged in the position of use of the coplanar formwork with said rectangular pieces (3) to form the flat faces (12) of the tower (1).
    Figures 4a to 4g show successive construction steps of the last three sections of the concrete tower (1) represented in Figures 1 and 2, using the climbing technique and the formwork parts shown in Figure 3; considering that in a tower of more than 120 m. in height the number of sections would be greater than 24 for a 5 meter formwork,
    Specifically, in figure 4a a first section (E n-2) of formwork is formed
    5
    10
    fifteen

    25

    35
    arranging four corner pieces (2a) with their lower ends (22) coplanarly and four pairs of intermediate rectangular pieces (3) arranged between, and laterally attached to, the corner pieces (2a).
    Then, as shown in Figure 4b, the concrete is poured into the first section of formwork (E n-2) and allowed to set to obtain a first section of the tower (T n-2).
    Then, as shown in Figures 4c and 4d, a second section of formwork (E n-1) is formed by removing one of the intermediate pieces (3) on each side thereof.
    The flat appendages (24) of rectangular triangular configuration defined on the opposite sides of the corner pieces (2a) have at their base a width equal to half the width of the rectangular pieces (3) which guarantees that in this second section of formwork (E n-1) the corner pieces (2a) and the rectangular pieces (3) are perfectly laterally attached, defining this second section of formwork (E n-1) internally a surface constituting a prolongation of the surface of the first tower section (T n-2) previously built.
    Subsequently, as shown in Figure 4d, concrete pouring into the second section of formwork (E n-1) is carried out to build a second tower section (T n-1).
    In order to make the formwork climbing, it is provided that the pieces of the formwork can be supported by anchors arranged in the anterior climb. So that either by means of a crane (climbing formwork) or with automatic climbing elements (self-climbing formwork), the formwork is positioned in successive climbs.
    The constant curvature of the corner pieces (2a) allows them to move in the direction of the generatrix of their curved area (23) to be arranged in the successive sections of the formwork, guaranteeing the definition in the tower of the cylindrical portions (13 ).

    As can be seen in Figures 4e and 4f, once the sections (T n-2, and T n-1) of the tower are constructed, the rectangular pieces (3) are removed from the second formwork section (E n-1). and the pieces (2a) are conveniently positioned to form a third section of formwork (E n) in which said corner pieces (2a) are directly attached to each other, this third section of formwork (E n) presenting a round upper mouth.
    By pouring concrete inside, as shown in Figure 4f, and setting it, a third and last section (T n) of the tower (1) represented in Figure 4g is formed.
    Figure 5 shows a variant embodiment of the formwork of Figure 3, which has an analogous operation to that described in Figures 4 and has a unique difference consisting in that the corner pieces (2b) lack flat appendages on their sides (24), this formwork comprising instead flat pieces (4), of rectangular triangular configuration, of dimensions analogous to the aforementioned flat appendages (24) and that fulfill the same function as those.
    With this formwork design, in the case of application in wind turbines, once the section corresponding to the last formwork section (E n) is defined, modifying the number of rectangular pieces (3) used in the formwork section corresponding to The base or lower end of the tower, you can build a tower with different base and height sizes, without having to modify the corner pieces (2b).
    A variant embodiment of the tower is shown in figures 6 and 7, with characteristics similar to the tower described above, but with three flat faces (12) and three cylindrical portions (13) instead of four; this case being constructed with a formwork, shown in Figure 8, in which the corner pieces (2a) have a corresponding curved area (23) with a cylindrical sector of an amplitude equal to one third of the contour of a cylinder.
    As can be seen in abruptly of the two embodiments of the formwork, shown in Figures 3 and 5, the corner pieces (2a, 2b) of the formwork are
    provided with holes (25) for anchoring the climbs or positioning of glues or self-climbing rails.
    Once the nature of the invention has been sufficiently described, as well as an example of preferred realization, it is stated for the appropriate purposes that the
    Materials, shape, size and disposition of the described elements may be modified, as long as this does not imply an alteration of the essential characteristics of the invention claimed below.
