Dispositivo para fijación de elementos de refuerzos en torres de celosíaDevice for fixing reinforcement elements in lattice towers

SECTOR DE LA TÉCNICATECHNIQUE SECTOR

La presente invención se refiere a un dispositivo que ha sido especialmente concebido para permitir vincular elementos de refuerzo tales como perfiles angulares o tubulares a torres de celosía ya existentes, en orden a incrementar su capacidad de carga ante la posible variación de los requerimientos previstos para dicha torre.The present invention refers to a device that has been specially designed to allow reinforcing elements such as angular or tubular profiles to be linked to already existing lattice towers, in order to increase their load capacity in the face of possible variations in the requirements provided for said tower.

El objeto de la invención es proporcionar unos medios de fijación de los elementos de refuerzo que eviten el tener que perforar o aplicar soldaduras sobre los perfiles de la torre de celosía, de modo que no se interfiera en la estructura principal, de manera que si dichos requisitos de carga se ven modificados o reducidos, la instalación de refuerzo se pueda desmontar fácilmente para volver a la estructura principal, la cual permanecerá intacta, resultando las maniobras de implantación de los refuerzos mucho más rápidas y económicas.The object of the invention is to provide fixing means for the reinforcement elements that avoid having to drill or apply welding on the profiles of the lattice tower, so as not to interfere with the main structure, so that if said load requirements are modified or reduced, the reinforcement installation can be easily dismantled to return to the main structure, which will remain intact, resulting in reinforcement implantation maneuvers much faster and cheaper.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En el ámbito de las telecomunicaciones, así como otros ámbitos en los que se utilizan torres de celosía 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 lattice towers are used as a means of supporting equipment, whether telecommunications, wind turbine nacelles, advertising signs, etc., these towers were designed according to relative specifications. to the load and behavior in front of 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 It would be 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 de celosía supone en muchos casos que la torre deba ser reforzada.Consequently, the change in loads for the lattice tower means in many cases that the tower must be reinforced.

Para reforzar estas estructuras se añaden a las mismas perfiles angulares y/o tubulares que se vinculan a la estructura principal mediante elementos de unión, que o bien se atornillan o se sueldan a dicha estructura.To reinforce these structures, angular and/or tubular profiles are added to them that are linked to the main structure by means of joining elements, which are either screwed or welded to said structure.

Así pues, la práctica de orificios o aplicación de soldaduras en la estructura principal interfiere en dicha estructura, de manera que en ninguno de los casos se puede volver a la estructura originalmente existente, por motivos evidentes en el caso de estructuras soldadas, mientras que en el caso de desatornillar la estructura de refuerzo, dicha estructura original se verá afectada negativamente por los orificios practicados sobre la misma para fijar la repetidamente citada estructura de refuerzo.Thus, the drilling of holes or the application of welds in the main structure interferes with said structure, so that in none of the cases can it be returned to the originally existing structure, for obvious reasons in the case of welded structures, while in In the case of unscrewing the reinforcing structure, said original structure will be negatively affected by the holes made thereon to fix the repeatedly mentioned reinforcing structure.

Paralelamente, tanto una como otra operativa suponen unos costes y tiempos muy elevados, a todas luces indeseables.At the same time, both one and the other operations involve very high costs and times, clearly undesirable.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El dispositivo que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero sumamente eficaz.The device that is recommended satisfactorily solves the aforementioned problems, based on a simple but highly effective solution.

Para ello, el dispositivo de la invención se constituye a partir de tres piezas principales que permiten una fácil y rápida instalación de los perfiles de refuerzo sobre la estructura de la torre de celosía.For this, the device of the invention is made up of three main parts that allow easy and quick installation of the reinforcing profiles on the structure of the lattice tower.

De forma más concreta, en el dispositivo de la invención participa una pieza principal de unión, en la que se define un sector central alargado en funciones de espaciador entre el perfil de la torre de que se trate y el perfil de refuerzo de la misma, sector central que se remata por ambos extremos en una horquilla, en forma de diedro recto por uno de sus extremos, el de adaptación al perfil de la torre a reforzar, mientras que por su extremo opuesto la horquilla puede ser igualmente en forma de diedro recto, si el perfil de refuerzo es angular, o bien en forma de omega si dicho perfil de refuerzo es tubular.More specifically, the device of the invention involves a main joining piece, in which an elongated central sector is defined as a spacer between the profile of the tower in question and its reinforcement profile, central sector that ends at both ends in a fork, in the form of a straight dihedral at one of its ends, that of adaptation to the profile of the tower to reinforce, while at its opposite end the fork can also be in the form of a straight dihedral, if the reinforcement profile is angular, or in the shape of an omega if said reinforcement profile is tubular.

En cualquiera de los casos, las horquillas presentarán unas expansiones en correspondencia con sus bordes libres dotadas de orificios para atornillado de las otras dos piezas que participan en el dispositivo.In any of the cases, the forks will present some expansions in correspondence with their free edges equipped with holes for screwing the other two pieces that participate in the device.

En tal sentido, las horquillas se adaptarán externamente al perfil angular de la torre y al perfil de refuerzo de que se trate, de modo que en el caso del perfil angular de la torre, interiormente a éste se dispondrá la segunda pieza, materializada en una pieza en forma de diedro recto, con una cartela de refuerzo interna, pieza que presenta sendas expansiones en sus extremos libres y dotadas de orificios, sobre los que se hacen pasar los tornillos de fijación de la horquilla correspondiente de la pieza principal.In this sense, the forks will adapt externally to the angular profile of the tower and to the reinforcement profile in question, so that in the case of the angular profile of the tower, the second piece will be arranged internally, materialized in a piece in the form of a straight dihedral, with an internal reinforcement bracket, a piece that presents two expansions at its free ends and equipped with holes, through which the fixing screws of the corresponding fork of the main piece are passed.

En el caso de que el perfil de refuerzo sea un perfil angular, la tercera pieza, de fijación a este perfil, será idéntica a la segunda pieza descrita, adaptándose al interior de dicho perfil y atornillándose a la horquilla complementaria de la pieza principal, mientras que, si se trata de un perfil de refuerzo tubular, esta tercera pieza se materializará en una pletina en forma de omega cuyos extremos libres estarán dotados de orificios para paso de los tornillos de fijación a la complementaria horquilla de la pieza principal.In the event that the reinforcing profile is an angular profile, the third piece, for fixing to this profile, will be identical to the second piece described, adapting to the interior of said profile and screwing to the complementary fork of the main piece, while that, if it is a tubular reinforcement profile, this third piece will materialize in an omega-shaped plate whose free ends will be equipped with holes for the fixing screws to the complementary fork of the main piece.

De esta forma se consigue un sistema de fijación de perfiles de refuerzo en torres de celosía ya existentes muy fácil y rápido de instalar, sin necesidad de tener que realizar taladrados o soldaduras, lo que reduce sensiblemente los tiempos operativos, así como la cualificación técnica necesaria de los operarios, todo lo cual redunda en una reducción de costos en la instalación así como la posibilidad de volver a la estructura inicial sin que ésta se vea alterada, en caso de modificarse los requisitos de carga de dicha torre de celosía. In this way, a fastening system for reinforcing profiles on already existing lattice towers is achieved, which is very easy and quick to install, without the need for drilling or welding, which significantly reduces operating times, as well as the necessary technical qualification. of the operators, all of which results in a reduction of costs in the installation as well as the possibility of returning to the initial structure without it being altered, in case the load requirements of said lattice tower are modified.

A la vista de las figuras reseñadas, puede observarse como en el dispositivo de la invención participan tres piezas principales, que pueden a su vez estar obtenidas a partir de mas piezas unidas entre sí. In view of the outlined figures, it can be seen how three main parts participate in the device of the invention, which in turn can be obtained from more parts joined together.

La primera de las piezas consiste en una pieza principal de unión (1), en la que se define un sector central (2) alargado en funciones de espaciador entre el perfil de la torre (3) de que se trate y el perfil de refuerzo angular (4) o tubular (4’) de la misma.The first of the pieces consists of a main joining piece (1), in which an elongated central sector (2) is defined as a spacer between the profile of the tower (3) in question and the reinforcement profile. angular (4) or tubular (4') thereof.

El sector central (2) se remata por ambos extremos en sendas horquillas principal (5) y secundaria (6-6’), la primera en forma de diedro recto, destinada a adaptarse externamente al perfil de la torre (3) a reforzar, mientras que la horquilla secundaria (6-6’) puede ser igualmente en forma de diedro recto, si el perfil de refuerzo es angular, tal como muestran las figuras 1 a 3, o bien en forma de omega si dicho perfil de refuerzo es tubular, como el mostrado en las figuras 4 a 6.The central sector (2) is finished off at both ends in two main (5) and secondary (6-6') forks, the first in the form of a straight dihedral, intended to adapt externally to the profile of the tower (3) to be reinforced, while the secondary fork (6-6') can also be in the form of a straight dihedral, if the reinforcement profile is angular, as shown in figures 1 to 3, or in the shape of an omega if said reinforcement profile is tubular. , as shown in figures 4 to 6.

Estas horquillas presentarán unas expansiones en correspondencia con sus bordes libres dotadas de orificios (7) para paso de tornillos (8) mediante las que se vinculan a las otras dos piezas que participan en el dispositivo.These forks will present some expansions in correspondence with their free edges equipped with holes (7) for the passage of screws (8) through which they are linked to the other two pieces that participate in the device.

La segunda pieza consiste en una pieza en forma de diedro recto (9), con una cartela de refuerzo interna (10), pieza que presenta sendas expansiones en sus extremos libres y dotadas de orificios, sobre los que se hacen pasar los tornillos (8) de fijación de la horquilla correspondiente de la pieza principal (1), adaptándose interna y ajustadamente al perfil de la torre (3), tal como se puede ver claramente en las figuras 2 y 4.The second piece consists of a piece in the shape of a straight dihedral (9), with an internal reinforcement bracket (10), a piece that presents two expansions at its free ends and equipped with holes, through which the screws (8) are passed. ) for fixing the corresponding fork of the main part (1), adapting internally and tightly to the profile of the tower (3), as can be clearly seen in figures 2 and 4.

Tal y como se ha dicho con anterioridad, en el caso de que el perfil de refuerzo sea un perfil angular (4), la tercera pieza, destinada a inmovilizar este perfil, se materializará al igual que en el caso de la segunda pieza, en una pieza en forma de diedro recto (9), con una cartela de refuerzo interna (10), pieza que presenta sendas expansiones en sus extremos libres y dotadas de orificios, sobre los que se hacen pasar los tornillos (8) de fijación de la horquilla secundaria (6) correspondiente de la pieza principal (1).As previously stated, in the event that the reinforcing profile is an angular profile (4), the third piece, intended to immobilize this profile, will be materialized in the same way as in the case of the second piece, in a piece in the shape of a straight dihedral (9), with an internal reinforcement bracket (10), a piece that presents respective expansions at its free ends and equipped with holes, over which the fixing screws (8) of the bracket are passed. secondary fork (6) corresponding to the main part (1).

Paralelamente, si el perfil de refuerzo se materializa en un perfil tubular (4’), la tercera pieza se materializará en una pletina de configuración en omega (11) cuyos extremos libres estarán dotados de orificios para paso de los tornillos de fijación (8) a la complementaria horquilla secundaria (6’) de la pieza principal (1).At the same time, if the reinforcing profile is materialized in a tubular profile (4'), the third piece will be materialized in an omega configuration plate (11) whose The free ends will be provided with holes for the fixing screws (8) to pass through the complementary secondary fork (6') of the main part (1).

De esta forma, y como se puede ver en las figuras, los perfiles de refuerzo podrán instalarse fácilmente reforzando los perfiles originales de la torre sin verse éstos afectos por orificios o soldaduras, manteniendo por tanto su integridad, lo que posibilitará la modificación posterior de la estructura, tanto si los requerimientos de carga aumentan como si disminuyen. In this way, and as can be seen in the figures, the reinforcement profiles can be easily installed reinforcing the original profiles of the tower without being affected by holes or welds, thus maintaining its integrity, which will make it possible to modify the structure later. structure, whether load requirements increase or decrease.
