Pilote en forma de c para una estructura metálica C-shaped pile for a steel structure

Campo técnicoTechnical field

La presente invención puede incluirse dentro del campo de la construcción, en particular, la construcción de estructuras metálicas. Más específicamente, la materia objeto de la invención se refiere a un pilote en forma de C para estructuras metálicas, que está, particularmente, pero no exclusivamente, destinado a estructuras metálicas de seguidores solares fotovoltaicos. The present invention may be included within the field of construction, in particular, the construction of metal structures. More specifically, the subject matter of the invention relates to a C-shaped pile for metal structures, which is particularly, but not exclusively, intended for metal structures for photovoltaic solar trackers.

AntecedentesBackground

En la industria de seguidores solares, pilotes de acero en forma de un perfil en forma de C simple (2), como se muestra en la vista superior de la figura 1, se usan comúnmente. Una característica de este perfil (2) es que su centro de masa (G) está trasladado de su centro de rotación (O), debido a su inercia de sección. Por lo tanto, cuando se aplica una fuerza de cizalla al perfil en forma de C (2) en su eje fuerte, el pilote tiende a rotar alrededor de su eje longitudinal, de modo que la resistencia máxima del perfil en forma de C (2) al esfuerzo de cizalla y el momento de flexión se reduce por los efectos de pandeo locales. In the solar tracker industry, steel piles in the form of a simple C-profile (2), as shown in the top view of Figure 1, are commonly used. A feature of this profile (2) is that its center of mass (G) is translated from its center of rotation (O), due to its section inertia. Therefore, when a shear force is applied to the C-profile (2) at its strong axis, the pile tends to rotate around its longitudinal axis, so that the maximum resistance of the C-profile (2) to shear stress and bending moment is reduced by local buckling effects.

El documento WO2014/162834A1 divulga un pilote en forma de C de acuerdo con el preámbulo de la reivindicación independiente 1. Los documentos US2018/334801A1 y US2021/340765A1 también se refieren a algunas otras características de la invención reivindicada. WO2014/162834A1 discloses a C-shaped pile according to the preamble of independent claim 1. US2018/334801A1 and US2021/340765A1 also refer to some other features of the claimed invention.

Breve descripción de la invenciónBrief description of the invention

La presente invención resuelve los inconvenientes anteriores por medio de un pilote en forma de C que, además de un perfil metálico, tal como un perfil de acero, con una sección convencional en forma de C, con una cabeza, comprende ventajosamente un accesorio en forma de U, ensamblado de una manera articulada en la cabeza del perfil. The present invention solves the above drawbacks by means of a C-shaped pile which, in addition to a metal profile, such as a steel profile, with a conventional C-shaped section, with a head, advantageously comprises a U-shaped accessory, assembled in an articulated manner on the head of the profile.

Con la adición del accesorio, se modifica la excentricidad en la aplicación de la carga, de modo que el centro de masa del ensamblaje de perfil accesorio se acerca, preferentemente coincide, con el centro de rotación de dicho ensamblaje durante el funcionamiento, con respecto a lo que se muestra en la figura 1, corrigiendo así el problema expuesto anteriormente y el pilote puede alcanzar sus valores de resistencia nominal, evitando la rotación de torsión alrededor del eje longitudinal del pilote y aumentando su resistencia a los efectos de carga de cizalla y momento de flexión. Por lo tanto, se logra una mayor resistencia de pilote, ya que el perfil es capaz de resistir una carga de pandeo más local debido al hecho de que el centro de masa y el eje de rotación ahora están más cerca juntos, donde preferentemente coinciden. With the addition of the accessory, the eccentricity upon load application is modified so that the centre of mass of the accessory profile assembly is brought closer, preferably coinciding, with the centre of rotation of said assembly during operation, with respect to that shown in figure 1, thus correcting the problem outlined above and the pile can reach its nominal strength values, preventing torsional rotation about the longitudinal axis of the pile and increasing its resistance to shear load and bending moment effects. Higher pile strength is therefore achieved as the profile is able to resist more local buckling load due to the fact that the centre of mass and the axis of rotation are now closer together, where they preferentially coincide.

El pilote objeto de la presente invención es aplicable en cualquier estructura metálica en la que los pilotes o pilares formados por perfiles de acero en forma de C sean susceptibles de incorporar regulación en uno de sus extremos. Ejemplo: aplicación a marcos y estructuras de acero que son fijos o móviles en uno o varios ejes, así como seguidores solares. The pile object of the present invention is applicable to any metal structure in which the piles or pillars formed by C-shaped steel profiles are susceptible to incorporating regulation at one of their ends. Example: application to steel frames and structures that are fixed or mobile on one or more axes, as well as solar trackers.

Se han llevado a cabo numerosas pruebas empíricas y han demostrado la eficacia del nuevo desarrollo, dando al pilote un aumento tanto en el porcentaje de resistencia elástica como el porcentaje de carga de flexión antes de alcanzar la plastificación. Numerous empirical tests have been carried out and have demonstrated the effectiveness of the new development, giving the pile an increase in both the percentage of elastic resistance and the percentage of bending load before reaching plastification.

Descripción detallada de una realización de ejemploDetailed description of an example embodiment

Una descripción detallada de una realización de ejemplo preferida de un pilote en forma de C (1) para una estructura metálica, objeto de la presente invención, se proporciona a continuación con la ayuda de las figuras adjuntas 1 a 5 mencionadas anteriormente. A detailed description of a preferred example embodiment of a C-shaped pile (1) for a metal structure, object of the present invention, is provided below with the aid of the attached figures 1 to 5 mentioned above.

El pilote (1) de la invención presenta, véanse las figuras 2 a 4, un perfil metálico en forma de C (2), tal como un perfil de acero, con una cabeza (3) en un extremo superior de acuerdo con una dirección longitudinal del perfil (2), en donde la cabeza (3) está destinada a ser activada para introducir el perfil (2) en el suelo. El perfil (2) incluye una cara central (4), de cuyos primeros extremos emergen caras laterales (5), que son perpendiculares a la cara central (4) y opcionalmente terminan en un ligero pliegue (6) hacia el interior en sus extremos libres. La cara central (4) y las caras laterales (5) definen juntas una abertura interior (7). The pile (1) of the invention presents, see figures 2 to 4, a C-shaped metal profile (2), such as a steel profile, with a head (3) at an upper end according to a longitudinal direction of the profile (2), where the head (3) is intended to be activated to introduce the profile (2) into the ground. The profile (2) includes a central face (4), from whose first ends emerge lateral faces (5), which are perpendicular to the central face (4) and optionally end in a slight fold (6) towards the interior at their free ends. The central face (4) and the lateral faces (5) together define an interior opening (7).

El pilote (1) incluye, además, véanse las figuras 2 a 3 y 5, un accesorio en forma de U (8), preferentemente hecho de chapa metálica, tal como acero. El accesorio (8) se ensambla en la cabeza (3) del perfil (2). Específicamente, el accesorio (8) comprende una cara intermedia plana (9) que se encuentra por encima de la cabeza (3) del perfil (2) y que mira hacia la abertura (7) del perfil (2), aunque con un cierto desplazamiento (10), que cubre la cara central (4), pero sin cubrir completamente la abertura (7). El accesorio (8) también comprende dos alas (11) que emergen oblicuamente de los segundos extremos de la cara intermedia (9) (véase la figura 2), que se superponen en las caras laterales (4) del perfil (2). The pile (1) further includes, see figures 2 to 3 and 5, a U-shaped fitting (8), preferably made of sheet metal, such as steel. The fitting (8) is assembled on the head (3) of the profile (2). Specifically, the fitting (8) comprises a flat intermediate face (9) which is located above the head (3) of the profile (2) and which faces the opening (7) of the profile (2), although with a certain offset (10), which covers the central face (4), but without completely covering the opening (7). The fitting (8) also comprises two wings (11) which emerge obliquely from the second ends of the intermediate face (9) (see figure 2), which overlap on the side faces (4) of the profile (2).

El pilote (1) también comprende dos articulaciones (12) correspondientes que involucran cada una de las alas (11) del accesorio (8) y la cara lateral (5) correspondiente del perfil (2), estando las articulaciones (12) orientadas a lo largo de un eje de rotación (13) común a ambas articulaciones (12), que permiten una rotación del accesorio (8) con respecto al perfil (2). The pile (1) also comprises two corresponding joints (12) involving each of the wings (11) of the accessory (8) and the corresponding lateral face (5) of the profile (2), the joints (12) being oriented along an axis of rotation (13) common to both joints (12), which allow a rotation of the accessory (8) with respect to the profile (2).

Medios de posicionamiento permiten que el accesorio (8) se fije en diferentes orientaciones en su rotación con respecto al perfil (2). En el ejemplo ilustrado en las figuras, los medios de posicionamiento comprenden: dos árboles (14) que sobresalen de las caras laterales (5) del perfil (2) hacia el exterior; y ranuras curvas (15) hechas en las alas (11) del accesorio (8) y alojando cada una un árbol (14) correspondiente e incluyendo posiciones (16) marcadas para retener los árboles (14). La figura 2 muestra tres posiciones (16). Positioning means allow the accessory (8) to be fixed in different orientations in its rotation with respect to the profile (2). In the example illustrated in the figures, the positioning means comprise: two shafts (14) protruding from the side faces (5) of the profile (2) towards the outside; and curved slots (15) made in the wings (11) of the accessory (8) and each housing a corresponding shaft (14) and including marked positions (16) to retain the shafts (14). Figure 2 shows three positions (16).

En una aplicación particular para seguidores solares fotovoltaicos, la incorporación del accesorio (8) permite, además, que el seguidor se adapte a ciertas tolerancias durante el ensamblaje, debido al tipo de terreno y el proceso de accionamiento de perfil en forma de C. De este modo, se pueden absorber las tolerancias en el eje longitudinal del pilote (1) - altura del seguidor - y la inclinación de la pendiente del terreno. De igual manera, incorpora orificios ranurados preferentemente curvos (17) en la cara intermedia (9) para la regulación de torsión cuando se acciona el perfil (2). In a particular application for photovoltaic solar trackers, the incorporation of the accessory (8) also allows the tracker to adapt to certain tolerances during assembly, due to the type of terrain and the C-shaped profile drive process. In this way, tolerances in the longitudinal axis of the pile (1) - height of the tracker - and the inclination of the ground slope can be absorbed. Likewise, it incorporates preferably curved slotted holes (17) in the intermediate face (9) for torsion regulation when the profile (2) is driven.
