Estructura de refuerzo para torres tubularesReinforcing structure for tubular towers
SECTOR DE LA TÉCNICATECHNIQUE SECTOR
La presente invención se refiere a una estructura de refuerzo para torres tubulares que si bien ha sido ideada y diseñada preferentemente para su aplicación en torres tubulares de soporte de antenas de telecomunicaciones, es igualmente aplicable a cualquier otra torre tubular, ya sea de acero u hormigón, como por ejemplo las utilizadas como soporte de publicidad, aerogeneradores, etc.The present invention refers to a reinforcement structure for tubular towers that, although it has been devised and designed preferably for its application in tubular towers to support telecommunications antennas, is equally applicable to any other tubular tower, whether made of steel or concrete. , such as those used as advertising support, wind turbines, etc.
El objeto de la invención es proporcionar una estructura que permita reforzar este tipo de torres ya existentes, cuando se requiera incrementar la carga que soportan las mismas, dejando el mástil existente con la menor carga posible, reduciendo el impacto medioambiental.The object of the invention is to provide a structure that makes it possible to reinforce this type of existing towers, when it is required to increase the load that they support, leaving the existing mast with the least possible load, reducing the environmental impact.
Es asimismo objeto de la invención proporcionar una estructura de refuerzo que sea modular, rápida y fácil de montar, incluso cuando el mástil de la torre deba atravesar tejados o cubiertas, garantizando la estanqueidad de las mismas.It is also the object of the invention to provide a reinforcement structure that is modular, quick and easy to assemble, even when the mast of the tower must pass through roofs or covers, guaranteeing their watertightness.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En el ámbito de las telecomunicaciones, así como otros ámbitos en los que se utilizan torres tubulares como medio de sustentación de equipos, ya sean de telecomunicaciones, góndolas de aerogeneradores, carteles publicitarios, etc, dichas torres fueron diseñadas de acuerdo a unas especificaciones relativas a la carga y comportamiento frente al viento para una aplicación específica, de manera que, por ejemplo, en el caso de las telecomunicaciones, los equipos instalados pueden quedar con el paso del tiempo obsoletos, debiendo instalar otros equipos o ampliar los existentes, así como resultar interesante compartir el mástil con otros operadores para así poder ahorrar costes en licencias, terrenos etc. In the field of telecommunications, as well as other fields in which tubular towers are used as a means of supporting equipment, whether telecommunications, wind turbine nacelles, advertising signs, etc., these towers were designed according to specifications related to the load and behavior against the wind for a specific application, so that, for example, in the case of telecommunications, the installed equipment may become obsolete over time, having to install other equipment or expand the existing ones, as well as being interesting to share the mast with other operators in order to save costs in licenses, land, etc.
Consecuentemente, el cambio de solicitaciones para la torre tubular supone en muchos casos que la torre deba ser reforzada o en su caso sustituida por otra, con los consecuentes costes que ello supone.Consequently, the change of solicitations for the tubular tower supposes in many cases that the tower must be reinforced or, where appropriate, replaced by another, with the consequent costs that this entails.
En tal sentido, en la patente de invención ES 2633 136 B2 se prevé el refuerzo de torres tubulares a través de su interior, mediante la implantación de estructuras metálicas que posteriormente quedan embebidas en hormigón.In this sense, the invention patent ES 2633 136 B2 provides for the reinforcement of tubular towers through their interior, through the implantation of metallic structures that are later embedded in concrete.
Si bien se trata de una solución que resuelve la problemática anteriormente expuesta, no es menos cierto que se trata de un proceso muy laborioso, caro y complicado, cuya aplicación además está limitada a torres tubulares de grandes diámetros, no siendo aplicable en torres de diámetros menores, como pueden ser la mayoría de torres utilizadas en telecomunicaciones.Although it is a solution that solves the aforementioned problem, it is no less true that it is a very laborious, expensive and complicated process, whose application is also limited to large diameter tubular towers, and is not applicable to towers of diameters minor, as can be the majority of towers used in telecommunications.
A mayor abundamiento, esta solución consiste en una solución irreversible, lo que no permite que el refuerzo aportado sea nuevamente replanteado en caso de cambiar nuevamente las necesidades de carga o comportamiento frente al viento.Furthermore, this solution consists of an irreversible solution, which does not allow the reinforcement provided to be reconsidered again in case the load needs or behavior against the wind change again.
Tratando de obviar esta problemática, el propio solicitante es titular del modelo de utilidad ES1258581, en el que se describe una estructura de refuerzo para torres tubulares que se constituye a partir de una pluralidad de módulos de celosía planos obtenidos a partir de tubo hueco, de sección circular y soldados en fábrica, agrupados en dos tipos; unos módulos de configuración esencialmente trapezoidal recta y unos módulos opcionales de configuración esencialmente rectangular, siendo unos y otros módulos acoplables entre sí mediante bridas complementarias, así como un elemento de coronación para la estructura de refuerzo, módulos que se distribuyen de forma radial y equiangularmente en planta alrededor de la torre tubular en un número mínimo de tres, vinculándose a dicha torre a través de montantes horizontales asociados a bridas a unas abrazaderas de fijación por atornillamiento a la torre tubular y al correspondiente módulo, formando alas radiales triangulares susceptibles de extenderse hasta la zona aproximadamente media de la torre, estructura que es susceptible de extenderse superiormente más allá de dicha zona a través de los módulos de configuración rectangular. Trying to avoid this problem, the applicant himself is the owner of utility model ES1258581, which describes a reinforcement structure for tubular towers that is made up of a plurality of flat lattice modules obtained from hollow tube, of circular section and factory welded, grouped into two types; some modules with an essentially straight trapezoidal configuration and some optional modules with an essentially rectangular configuration, each module being interconnectable by means of complementary flanges, as well as a crowning element for the reinforcement structure, modules that are distributed radially and equiangularly in plant around the tubular tower in a minimum number of three, being linked to said tower through horizontal uprights associated with flanges to clamps for fixing by screwing to the tubular tower and the corresponding module, forming triangular radial wings capable of extending up to the approximately middle area of the tower, a structure that is capable of extending beyond said area through the modules of rectangular configuration.
Así pues, se trata de módulos a base de celosía cuya fabricación resulta sumamente lenta y laboriosa, repercutiendo muy negativamente en el precio de la estructura.Thus, these are lattice-based modules whose manufacture is extremely slow and laborious, having a very negative impact on the price of the structure.
Otro problema que presenta este tipo de refuerzos aparece cuando la torre a reforzar atraviesa un tejado o cubierta, lo que obliga a que la estructura de refuerzo atraviese igualmente dicha cubierta, de modo que al tratarse de una estructura en celosía, han de practicarse ventanas de considerable tamaño sobre dicha cubierta, difíciles de estanqueizar una vez montado el refuerzo.Another problem that this type of reinforcement presents appears when the tower to be reinforced goes through a roof or roof, which forces the reinforcement structure to also go through said roof, so that since it is a lattice structure, windows must be made. considerable size on said cover, difficult to seal once the reinforcement is assembled.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
La estructura de refuerzo para torres tubulares que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla, pero sumamente eficaz.The reinforcing structure for tubular towers that the invention proposes fully satisfactorily resolves the aforementioned problem, based on a simple but highly effective solution.
La estructura está prevista para ser aplicada en torres tubulares ya existentes, destinadas a soportar elementos pesados, como por ejemplo equipos de telecomunicaciones, sin descartar otros elementos, como pueden ser carteles publicitarios, góndolas de aerogeneradores, etc,The structure is planned to be applied to already existing tubular towers, designed to support heavy elements, such as telecommunications equipment, without ruling out other elements, such as advertising posters, wind turbine nacelles, etc.
De forma más concreta, la estructura de refuerzo de la invención se constituye a partir de dos elementos principales.More specifically, the reinforcing structure of the invention is made up of two main elements.
El primer elemento principal se materializa en unas abrazaderas que se fijan a la estructura tubular de la torre cada cierta altura preestablecida, abrazaderas que incluyen unos brazos radiales que emergen de las mismas sobre un imaginario plano horizontal, y que participan en número mínimo de tres, distribuidos equiangularmente en planta y que se rematan en asientos en forma de omega de fijación para el segundo elemento.The first main element is materialized in clamps that are fixed to the tubular structure of the tower every certain pre-established height, clamps that include radial arms that emerge from them on an imaginary horizontal plane, and that participate in a minimum number of three, distributed equiangularly in plan and finished off with omega-shaped seats for fixing the second element.
El segundo elemento consiste en los elementos de refuerzo propiamente dichos, materializados en tubos huecos, de sección circular y soldados en fábrica, que se rematan por sus extremos libres en bridas para su atornillamiento a otros tubos del mismo tipo dando continuidad vertical hasta la zona extrema superior de la torre, donde se emplearán unos elementos de coronación igualmente vinculables a la correspondiente abrazadera superior.The second element consists of the reinforcing elements themselves, materialized in hollow tubes, circular in section and welded in the factory, which are finished off at their free ends in flanges for screwing to other tubes of the same type, giving vertical continuity to the upper end area of the tower, where some crowning elements will be used. equally linkable to the corresponding upper bracket.
De esta manera, se evita el empleo de celosías, como ocurría en el modelo de utilidad ES 2633 136 B2, de modo que la inexistencia de los tirantes diagonales de las celosías se compensa con una mayor altura de los tubos que participan en el refuerzo, simplificando significativamente el número de piezas distintas a fabricar y facilitando la implantación de este tipo de estructuras en torres tubulares que atraviesan tejados o cubiertas, ya que en este caso solo es preciso realizar tres orificios circulares sobre dicha cubierta para paso de los correspondientes tubos, orificios de menor tamaño que las ventanas que serían necesarias practicar para paso de las correspondientes celosías, y que resultan mucho mas fáciles de estanqueizar.In this way, the use of trusses is avoided, as was the case in utility model ES 2633 136 B2, so that the absence of diagonal braces in the trusses is compensated with a greater height of the tubes that participate in the reinforcement, significantly simplifying the number of different parts to be manufactured and facilitating the implementation of this type of structure in tubular towers that go through roofs or roofs, since in this case it is only necessary to make three circular holes on said roof for the passage of the corresponding tubes, holes smaller than the windows that would be necessary to make for the passage of the corresponding lattices, and which are much easier to seal.
No obstante, si los requerimientos de carga son muy elevados, la estructura podrá reforzarse mediante la inclusión de una segunda alineación de tubos verticales, que se dispondrán paralela, radial y exteriormente a los tubos principales, mediante brazos separadores que se atornillen entre cada pareja de tubos, lo que permite modificar estructuras ya reforzadas con unas modificaciones mínimas y consecuentemente con unos tiempos operativos igualmente reducidos.However, if the load requirements are very high, the structure can be reinforced by including a second line of vertical tubes, which will be arranged parallel, radially and externally to the main tubes, by spacer arms that are screwed between each pair of tubes, which allows already reinforced structures to be modified with minimal modifications and consequently with equally reduced operating times.
Se consigue por tanto a partir de esta estructuración, un sistema de refuerzo de torres tubulares ya existentes estructuralmente mucho mas sencillo, económico, fácil y rápido de instalar.Therefore, from this structure, a reinforcement system for already existing tubular towers is structurally much simpler, cheaper, easier and faster to install.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas, y en especial de la figura 1, puede observarse como la invención está destinada a ser aplicada a torres tubulares (1) ya existentes, destinadas a soportar elementos pesados, como por ejemplo equipos de telecomunicaciones, sin descartar otros elementos. In view of the outlined figures, and especially figure 1, it can be seen how the invention is intended to be applied to already existing tubular towers (1), intended to support heavy elements, such as telecommunications equipment, without ruling out other elements.
Pues bien, de acuerdo ya con la esencia de la invención se ha previsto que la estructura de refuerzo de la invención se constituya a partir de una pluralidad de abrazaderas (2) destinadas a fijarse por atornillamiento sobre la estructura tubular de la torre cada cierta altura, abrazaderas que incluyen al menos tres brazos radiales (3) preferentemente distribuidos equiangularmente sobre un imaginario plano horizontal y que se rematan por su extremidad libre en respectivos asientos (4) en forma de omega dotados de orificios para paso de tornillos (6) de fijación que mediante pletinas en omega (5) igualmente dotadas de orificios para paso de los tornillos (6), permiten la fijación de unos tubos (7) de naturaleza metálica, materializados en tubos huecos, de sección circular y soldados en fábrica, que se rematan por sus extremos libres en bridas (8) para su atornillamiento a otros tubos (7) del mismo tipo.Well, in accordance with the essence of the invention, it has been provided that the reinforcing structure of the invention is constituted from a plurality of clamps (2) intended to be fixed by screwing on the tubular structure of the tower every certain height. , clamps that include at least three radial arms (3) preferably equiangularly distributed on an imaginary horizontal plane and that end at their free end in respective omega-shaped seats (4) equipped with holes for the passage of fixing screws (6). that by means of omega plates (5) also equipped with holes for the passage of the screws (6), allow the fixing of tubes (7) of a metallic nature, materialized in hollow tubes, of circular section and welded in the factory, which are finished off by their free ends in flanges (8) for screwing to other tubes (7) of the same type.
Tal y como se ha dicho con anterioridad, estos tubos (7) conjuntamente con los brazos radiales (3) de las abrazaderas (2) permiten formar una estructura de refuerzo alrededor de la torre tubular (1) sin necesidad de celosías, simplemente incrementando la altura hasta la que se extienden dichos tubos (7), simplificando sensiblemente la estructura del refuerzo y consecuentemente su instalación.As previously stated, these tubes (7) together with the radial arms (3) of the clamps (2) make it possible to form a reinforcement structure around the tubular tower (1) without the need for lattices, simply increasing the height up to which said tubes (7) extend, considerably simplifying the structure of the reinforcement and consequently its installation.
En tal sentido, y como se muestra en las figuras 3, 4, 7 y 8, el extremo superior de estos tubos (7) se vinculará finalmente al tramo superior de la torre a través de una estructura de coronación (9) a base de tubos diagonales que se vinculan a su vez a una abrazadera (2’) fijada al mástil de la torre en este último tramo.In this sense, and as shown in figures 3, 4, 7 and 8, the upper end of these tubes (7) will finally be linked to the upper section of the tower through a crown structure (9) based on Diagonal tubes that are linked in turn to a clamp (2') fixed to the mast of the tower in this last section.
Tal y como se puede observar en las figuras 5 a 8, si los requerimientos de carga son muy elevados, la estructura podrá reforzarse mediante la inclusión de una segunda alineación de tubos (7’) verticales, que se dispondrán paralela, radial y exteriormente a los tubos principales, y se fijarán a éstos mediante brazos separadores (10), dotados de abrazaderas que se atornillan entre cada pareja de tubos.As can be seen in figures 5 to 8, if the load requirements are very high, the structure can be reinforced by including a second line of vertical tubes (7'), which will be arranged parallel, radial and externally to the main tubes, and they will be fixed to them by means of separator arms (10), equipped with clamps that are screwed between each pair of tubes.
Estos tubos (7’) adicionales se rematarán superiormente con un tubo de coronación (9’) diagonal equivalente a la estructura de coronación (9). These additional tubes (7') will be finished off at the top with a diagonal crown tube (9') equivalent to the crown structure (9).
