REALIZACIÓN PREFERENTE DE LA INVECIÓN  Figure 1 1: shows a perspective view of the structure object of the present invention with three straight beams. PREFERRED REALIZATION OF THE INVENTION
La estructura se inicia con un tubo (1 ) al que se sueldan un número variable de cartelas (2), al menos 3, aunque preferiblemente al menos 4, en planos radiales. En esas cartelas se fijan vigas metálicas de directriz recta (3), preferentemente tipo UPN, es decir, con sección con forma de U, o CF, es decir, con sección con forma de C, formando una estrella, pero no plana sino cónica. The structure starts with a tube (1) to which a variable number of cartels (2) are welded, at least 3, but preferably at least 4, in radial planes. These beams are fixed metal beams of direct guideline (3), preferably UPN type, that is, with a U-shaped section, or CF, that is, with a C-shaped section, forming a star, but not flat but conical.
Sobre esa estrella cónica de vigas rectas se fijan anillos circulares de diferente radio (5) en base al menor o mayor tamaño de las láminas reflectantes a emplear. Conviene destacar que dichas vigas pueden tener en lugar de una directriz recta una directriz curva (10), formando una estrella cóncava. Dichas vigas de directriz curva (10) pueden ser fabricadas por estampación.  On that conical star of straight beams, circular rings of different radius (5) are fixed based on the smaller or larger size of the reflective sheets to be used. It should be noted that said beams may have a curved directive (10) instead of a straight guideline, forming a concave star. Said curved guide beams (10) can be manufactured by stamping.
La unión entre la estrella y los anillos se realiza preferentemente mediante unos soportes (6) que se fijan en cada viga recta (3) o curva (10) mediante tornillo y agujero rasgado o coliso (9) o similar, permitiendo el desplazamiento de cada anillo en la dirección del eje del paraboloide, y por lo tanto la regulación y ajuste en esa dirección.  The connection between the star and the rings is preferably carried out by means of supports (6) that are fixed on each straight beam (3) or curve (10) by means of a screw and torn hole or coliseum (9) or similar, allowing the displacement of each ring in the direction of the paraboloid axis, and therefore the adjustment and adjustment in that direction.
La unión entre las láminas reflectantes y los anillos se propone sea realizada mediante abrazaderas (7) con tornillo de inmovilización y fijación en el anillo y ranura de ajuste (agujero rasgado o coliso) de montaje del espárrago (8) de unión con la lámina reflectante (4).  The union between the reflective sheets and the rings is proposed to be carried out by means of clamps (7) with locking screw and fixation in the ring and adjustment slot (torn hole or collision) of mounting the stud (8) of union with the reflective sheet (4).
El espárrago puede ser roscado permitiendo una segunda regulación en su dirección axial. La fijación del espárrago a la lámina reflectante puede realizarse mediante adhesivo, agujero y arandelas y tuercas, etc.  The stud can be threaded allowing a second adjustment in its axial direction. The fixing of the stud to the reflective sheet can be done by means of adhesive, hole and washers and nuts, etc.
Las abrazaderas permiten su giro alrededor del anillo o anillos, pudiendo recibir el espárrago de la lámina en su ángulo natural.  The clamps allow its rotation around the ring or rings, being able to receive the stud of the blade at its natural angle.
