Abstract

Solar collector module of the type used in solar energy concentration plants, and more specifically, the structures used to hold or support the mirrors and receivers used to concentrate the solar radiation. This structure has a series of characteristics that increase its efficiency in respect of the prior art: addition of box-shaped fins in the nodes to facilitate connection of the bars, use of flat or hollow connectors to attach the bar to the node, creating an asymmetric structure with bars considerably more reinforced than others, which will be used to support the load, division of the longitudinal flange that runs around the structure into discrete segments and removal of those not applying any force, movement of the nodes to better locations and creation of a long node (flange) to which the bars are connected directly using the fins without the need for any nodes.

Description

MÓDULO DE COLECTOR SOLAR  SOLAR COLLECTOR MODULE
Sector técnico de la invención  Technical sector of the invention
Esta invención se refiere a los módulos de colectores solares de los usados en una planta de concentración de energía solar, más concretamente, a las estructuras que se utilizan para mantener o soportar los espejos y los receptores encargados de concentrar la radiación solar.  This invention relates to the solar collector modules of those used in a solar energy concentration plant, more specifically, to the structures that are used to maintain or support the mirrors and the receivers in charge of concentrating the solar radiation.
Antecedentes de la invención  BACKGROUND OF THE INVENTION
En las plantas de colectores solares se emplean estructuras soporte para los espejos encargados de concentrar la radiación solar. En general, todos ellos poseen además un dispositivo que les permite orientarse en dirección al sol, denominado seguidor solar, el cual permite un seguimiento muy exacto del sol que conduce a la obtención de altos rendimientos.  In the solar collector plants, support structures are used for the mirrors responsible for concentrating the solar radiation. In general, all of them also have a device that allows them to be oriented towards the sun, called solar tracker, which allows a very accurate tracking of the sun that leads to obtaining high yields.
La invención que aquí se reivindica hace referencia a la estructura soporte del módulo, sin entrar a reivindicar el seguidor solar que luego se le podrá acoplar.  The invention claimed here refers to the support structure of the module, without going into claiming the solar tracker that can then be coupled to it.
Existe una gran cantidad de estado de la técnica referente a las estructuras soporte de módulos de colectores solares, como pueden ser las patentes US6414237, US5069540, ES2326303, ES2161589, CA1088828, EP0082068 y muchas otras. Pero quizá unos detalles más cercanos de los módulos de colectores solares que la invención describe se encuentran en la solicitud de modelo de utilidad española U1070880 que se presentó el 1 de julio de 2009 y titulada "Seguidor Solar de Concentración Térmica". There is a large amount of state of the art concerning the support structures of solar collector modules, such as the patents US6414237, US5069540, ES2326303, ES2161589, CA1088828, EP0082068 and many others. But perhaps closer details of the solar collector modules described by the invention can be found in the Spanish utility model application U1070880, which was submitted on July 1, 2009 and entitled "Solar Thermal Concentrator".
En ella se describe una estructura de celosía que determina unos brazos mediante los que define una forma cilindro-parabólica para la colocación de los espejos. Cada uno de los brazos está formado por un conjunto de perfiles unidos, sobre los cuales va dispuesto en el borde frontal un perfil curvado según la curvatura de la formación cilindro-parabólica de colocación de los espejos componentes del concentrador térmico. Para esta estructura sólo se usa un tipo de piezas de amarre independientemente de la carga que soporten las mismas en la estructura y por lo tanto no teniendo en cuenta la diferencia de cargas soportadas en los diferentes puntos de la estructura.  It describes a lattice structure that determines arms through which defines a parabolic-cylinder shape for the placement of the mirrors. Each of the arms is formed by a set of joined profiles, on which a profile curved according to the curvature of the cylinder-parabolic formation of the component mirrors of the thermal concentrator is arranged on the front edge. For this structure, only one type of lashing pieces is used independently of the load that they support in the structure and therefore not taking into account the difference of loads supported in the different points of the structure.
A la vista del estado de la técnica, la invención aquí reivindicada pretende divulgar una estructura que, aún a pesar de estar formada por una estructura reticular del tipo nudos y barras, tiene una serie de características que hacen que difiera substancial- mente de las conocidas en el estado de la técnica, aportando una serie de ventajas, tanto de resistencia estructural, pues se consigue que soporte mayores cargas, como en el proceso de fabricación, pues se simplifica en gran medida, como en costes consiguiendo, para la misma respuesta mecánica un importante abaratamiento o para el mismo coste, mejores características técnicas. In view of the state of the art, the claimed invention aims to disclose a structure that, despite being formed by a lattice structure of the knots and bars type, has a series of characteristics that make it differ substantially. of those known in the state of the art, providing a series of advantages, both of structural strength, since it is possible to support higher loads, as in the manufacturing process, as it is greatly simplified, as in costs getting, for the same mechanical response an important cheapening or for the same cost, better technical characteristics.
Descripción de la invención  Description of the invention
La invención consiste en una estructura que sirve de soporte para los espejos o los receptores de un módulo de concentración solar.  The invention consists of a structure that serves as support for the mirrors or receivers of a solar concentration module.
La estructura comprende un entramado de barras realizado preferiblemente en aluminio, de manera que resista las agresiones climatológicas, teniendo en cuenta que toda su vida útil trabajará a la intemperie.  The structure comprises a bar structure made preferably of aluminum, so that it resists weather aggressions, taking into account that its entire useful life will work outdoors.
Esas barras se conectan entre ellas mediante unos nodos o uniones rígidas, que no cuentan con ningún grado de libertad.  These bars are connected to each other by means of rigid nodes or unions, which do not have any degree of freedom.
Existen diferentes denominaciones para las barras que componen este tipo de estructuras en función de la posición que ocupen. Se denominan cordones aquellas barras que recorren la estructura de un extremo a otro longitudinalmente y diagonales aquellas que conectan un nodo con otro siguiendo una línea diagonal.  There are different names for the bars that make up this type of structure depending on the position they occupy. Laces are called those bars that run the structure from one end to another longitudinally and diagonal those that connect one node with another following a diagonal line.
Los puntales son las piezas que conforman los tramos finales de las barras, por donde se conectan a los nodos y que se diseñan para resistir presión. Suelen ser de geometría circular o semicircular. The struts are the pieces that make up the final sections of the bars, where they are connected to the nodes and designed to withstand pressure. They are usually of circular or semicircular geometry.
De forma general, esta estructura o armazón cuenta con una serie de características que la diferencian de las estructuras hasta ahora conocidas en el estado de la técnica. Estas características son:  In general, this structure or frame has a series of characteristics that differentiate it from the structures known up to now in the state of the art. These characteristics are:
• Nodos con aletas en forma de caja • Nodes with box-shaped fins
A los nodos utilizados para realizar las conexiones de las barras se les añaden unas aletas o lengüetas de sección rectangular (tipo caja), diseñadas para poder conectar unas barras con otras. En el estado de la técnica los nodos sujetan las barras de la estructura entre pestañas paralelas opuestas o incluso, utilizan una única pestaña, lo que limita la resistencia de la estructura.  To the nodes used to make the connections of the bars are added fins or tongues of rectangular section (box type), designed to be able to connect some bars with others. In the state of the art the nodes hold the bars of the structure between opposite parallel flanges or even use a single flange, which limits the strength of the structure.
La invención propuesta, con las aletas en forma de caja, reduce al mínimo el tamaño de la sección del nodo suponiendo un ahorro importante para el proceso de fabricación por extrusión; además permite la utilización de barras más grandes, más rígidas y más fuertes y consigue que los elementos de la aleta sean más fuertes y dimensio- nalmente más estables, tanto durante el proceso de fabricación como durante su uso. The proposed invention, with the box-shaped fins, minimizes the size of the section of the node assuming significant savings for the manufacturing process by extrusion; It also allows the use of larger, stiffer and stronger bars and makes the fin elements stronger and more dimensioned. more stable, both during the manufacturing process and during its use.
Las aletas cajeadas del nodo permiten varias alternativas para la conexión de los puntales de las barras a los nodos. El utilizar un tipo u otro de conexión dependerá de la carga que soporte la estructura, del tamaño de los puntales, del tamaño de los nodos y de las limitaciones de fabricación.  The recessed fins of the node allow several alternatives for the connection of the struts of the bars to the nodes. The use of a connection type or another will depend on the load that supports the structure, the size of the props, the size of the nodes and manufacturing limitations.
La conexión de los puntales a los nodos podría tener un único elemento de unión, pero se suelen utilizar más para lograr una sujeción fija o rígida. Este hecho de tener múltiples elementos de unión incrementa la resistencia de la estructura permitiendo que el nodo soporte tanto las cargas axiales como los momentos.  The connection of the struts to the nodes could have a single joining element, but they are usually used more to achieve a fixed or rigid grip. This fact of having multiple joining elements increases the strength of the structure allowing the node to support both the axial loads and the moments.
Una opción de diseño consiste en que las barras tengan conectores preinstalados en los puntales los cuales se unen al nodo directamente para montar la estructura.  A design option is that the bars have pre-installed connectors on the struts which are attached to the node directly to assemble the structure.
Un conector es un elemento estructural adicional unido a la barra y que tiene características tales como taladros que facilitan la conexión de la barra al nodo. Los conecto- res proporcionan una serie de ventajas, incluyendo que facilitan la transición entre la forma de la barra y la forma del nodo, al mismo tiempo que proporcionan a la estructura resistencia adicional.  A connector is an additional structural element attached to the bar and has features such as holes that facilitate the connection of the bar to the node. The connectors provide a number of advantages, including facilitating the transition between the shape of the bar and the shape of the node, while at the same time providing the structure with additional strength.
Diferentes alternativas del montaje de los puntales se describirán más adelante, en la realización preferente de la invención.  Different alternatives of mounting the struts will be described later, in the preferred embodiment of the invention.
-· Una estructura reforzada dentro de la estructura general.  - · A reinforced structure within the general structure.
Los diseños convencionales de estructuras o armazones, están diseñados suponiendo que van a soportar cargas simétricas, a través de un montaje de transferencia de momentos. Se diseñan las estructuras pensando en distribuir las cargas tan uniformemente como sea posible entre sus barras. Esto hace que las barras tengan todas el mismo tamaño (lo que facilita conexiones con el nodo) al mismo tiempo que reduce al mínimo los requisitos de fuerza para barras individuales. The conventional designs of structures or frames are designed assuming that they will support symmetrical loads, through a moment transfer assembly. The structures are designed thinking of distributing loads as evenly as possible between their bars. This makes the bars all the same size (which facilitates connections to the node) while minimizing the strength requirements for individual bars.
Sin embargo una estructura se puede diseñar para que concentre la carga principal en una localización determinada, concretamente en uno de los vértices, de manera que transmita directamente la fuerza desde ese punto atravesando toda la estructura, hasta salir por otro de los vértices. However, a structure can be designed to concentrate the main load in a specific location, specifically in one of the vertices, in such a way that it directly transmits the force from that point through the entire structure, until it leaves through another of the vertices.
Con esta realización, se obtienen unas barras mucho más reforzadas que otras, pues serán las que verdaderamente estén sometidas a esfuerzos.  With this embodiment, bars are obtained much more reinforced than others, since they will be the ones that are really subjected to stresses.
• Asimetría de la estructura Como se ha dicho anteriormente, los diseños convencionales de este tipo de estructuras (y de hecho los diseños convencionales de tubos de torsión y de cerchas) se basan en la asunción fundamental de la entrada simétrica de la carga, a través de un eje de transferencia del esfuerzo de torsión y de una placa de torsión situados centrados en el plano del centro de la estructura. Esto da lugar a los habituales diseños de las estructuras que son, en su mayoría simétricos respecto del plano del centro. En el apartado anterior ya se introdujo el hecho de variar está condición de simetría utilizando una serie de barras que resistiesen más carga que otras. Así pues, podemos contar con una estructura o armazón simétrico respecto a un plano del centro, pero asimétrico respecto a un plano longitudinal del centro, con unas barras mucho más grandes que otras para cumplir las condiciones asimétricas de carga. • Asymmetry of the structure As mentioned above, the conventional designs of this type of structure (and in fact the conventional designs of torsion tubes and trusses) are based on the fundamental assumption of the symmetrical input of the load, through a transfer axis of torque and a torsion plate located centered on the plane of the center of the structure. This gives rise to the habitual designs of the structures that are, in their majority symmetrical with respect to the plane of the center. In the previous section, the fact of varying this condition of symmetry was introduced using a series of bars that withstand more load than others. Thus, we can have a symmetrical structure or framework with respect to a center plane, but asymmetric with respect to a longitudinal plane of the center, with bars much larger than others to meet the asymmetric loading conditions.
La ventaja principal de una estructura asimétrica de este tipo es la eficiencia del material. En el caso de tener una estructura que se diseñe para soportar las cargas por el borde, un lado tendrá la estructura más reforzada que el otro y este último incluso puede contar con menos barras. En cualquier caso, la estructura total puede cumplir requisitos de diseño con menos material.  The main advantage of an asymmetric structure of this type is the efficiency of the material. In the case of having a structure that is designed to support the loads by the edge, one side will have the structure more reinforced than the other and the latter may even have fewer bars. In any case, the total structure can meet design requirements with less material.
• Cordón dividido en segmentos individuales • Cord divided into individual segments
Otra de las características que presentan las estructuras de la invención, es el hecho de dividir los cordones (las grandes barras longitudinales que recorren la estructura de un extremo al otro) en elementos individuales menores, es decir, en lugar de tener un gran cordón de una sola pieza que recorre toda la estructura, se divide en una serie de segmentos individuales menores.  Another feature presented by the structures of the invention, is the fact of dividing the cords (the large longitudinal bars that run the structure from one end to the other) in smaller individual elements, that is, instead of having a large cord. a single piece that runs through the entire structure, is divided into a series of smaller individual segments.
Estos elementos individuales se fabrican más fácilmente y con mayor precisión. Asimismo, el montaje final también se simplifica drásticamente al basarse en elementos de tamaños mucho más pequeños.  These individual elements are manufactured more easily and with greater precision. Also, the final assembly is also drastically simplified by relying on elements of much smaller sizes.
Adicionalmente, los elementos individuales a lo largo del eje del cordón se pueden optimizar de forma individual para maximizar la eficacia estructural y de material, tal y como se planteaba anteriormente para ciertas barras.  Additionally, the individual elements along the cord axis can be individually optimized to maximize the structural and material efficiency, as previously stated for certain bars.
Si se utiliza un cordón único, sin dividir, la sección de dicho cordón ha de ser constante a lo largo de toda su longitud, por la naturaleza de los procesos de extrusión y de ensamblaje y ha de estar dimensionada está sección para resolver la carga máxima esperada en cualquier punto del eje del cordón. Dividiendo el cordón, pode- mos eliminar tramos enteros y reducir la sección de otros, en función de la carga que vayan a soportar, optimizando costes. If a single, undivided bead is used, the section of said bead must be constant along its entire length, due to the nature of the extrusion and assembly processes and this section must be dimensioned to solve the maximum load expected at any point of the cord axis. Dividing the cord, can We eliminate entire sections and reduce the section of others, depending on the load they will support, optimizing costs.
• Eliminación de cordones  • Elimination of laces
Se demuestra que hay secciones del cordón que no soportan ningún esfuerzo y que se pueden omitir sin un efecto significativo sobre la fuerza o la rigidez del bastidor, especialmente cuando el esfuerzo de torsión se transmite entre los módulos adyacentes utilizando un cordón lateral.  It is shown that there are sections of the cord that do not support any effort and that can be omitted without a significant effect on the strength or rigidity of the frame, especially when the torque is transmitted between the adjacent modules using a lateral cord.
La omisión de los cordones puede proporcionar un ahorro en costes significativo, debido a la reducción del material requerido para hacer la estructura, así como la reducción de trabajo requerido para montarla.  The omission of the cords can provide a significant cost savings, due to the reduction of the material required to make the structure, as well as the reduction of work required to assemble it.
Además, la omisión de algún cordón permite la colocación independiente de los nodos que, de otra manera, se podría haber visto determinada por la posición de los cordones. Los nodos y sus nodos asociados se pueden colocar en localizaciones estructuralmente más eficientes.  In addition, the omission of a cord allows the independent placement of the nodes that, otherwise, could have been determined by the position of the cords. The nodes and their associated nodes can be placed in structurally more efficient locations.
• Nodos de "longitud total"  • "Total length" nodes
Se trata de una opción de realización en la que en lugar de nodos, se utiliza un cordón de longitud igual a la longitud total del colector. Los puntales de las barras de la estructura se conectan directamente a este cordón aleteado por cualquier método apropiado.  It is an implementation option in which instead of nodes, a cord of length equal to the total length of the collector is used. The struts of the bars of the structure are connected directly to this finned cord by any appropriate method.
Esto podría tener una penalización en material pero podría simplificar drásticamente la fabricación y el montaje de la estructura pues se evitarían las uniones nodo- cordón.  This could have a material penalty but could drastically simplify the fabrication and assembly of the structure as the node-cord joints would be avoided.
• Nodo con sistema de unión independiente  • Node with independent union system
Se trata de una alternativa para realizar las conexiones entre los elementos de la estructura. En este caso se utilizan una serie de aletas o pestañas sujetas a las barras con remaches, tornillos, pernos, soldadura o cualquier sistema de unión equivalente, en las cuales se conectan las barras o puntales que se vayan a conectar. Este diseño es potencialmente ventajoso debido a su simplicidad y porque permite que el diseñador lo simplifique aún más eliminando las piezas de terminación del puntal. It is an alternative to make the connections between the elements of the structure. In this case, a series of fins or tabs are used attached to the bars with rivets, screws, bolts, welding or any equivalent joint system, in which the bars or struts to be connected are connected. This design is potentially advantageous because of its simplicity and because it allows the designer to simplify it further by eliminating the strut termination pieces.
• Separación del espejo. • Separation of the mirror.
De acuerdo con otra realización, se pueden proporcionar unos espaciadores para distanciar adecuadamente el espejo o los espejos de la estructura. Estos espaciadores son piezas extruídas que actúan como puente entre las estructuras de geometría plana y los espejos, de geometría parabólica. Estos espaciadores se sitúan . en los extremos del colector, donde la diferencia de alturas entre ambos es mayor. According to another embodiment, spacers can be provided to adequately distance the mirror or mirrors from the structure. These spacers are extruded pieces that act as a bridge between geometry structures flat and the mirrors, of parabolic geometry. These spacers are located. at the ends of the collector, where the difference in height between the two is greater.
Gracias a estos espaciadores los espejos pueden ser soportados directamente por la estructura sin tener la necesidad de instalar una correa longitudinal, más concreta- mente, por los cordones y barras de los extremos del módulo. Así, el cordón cumple una doble función de actuar como elemento estructural y como soporte del espejo, con el consiguiente ahorro de material al no necesitar correa y acentuado aquí puesto que se requeriría una correa muy larga.  Thanks to these spacers the mirrors can be supported directly by the structure without the need to install a longitudinal belt, more specifically, by the cords and bars of the ends of the module. Thus, the cord fulfills a double function of acting as a structural element and as a support for the mirror, with the consequent saving of material by not needing a strap and accentuated here since a very long strap would be required.
Esta estructura se diseña especialmente para su aplicación como soporte o armazón de los espejos de un colector solar, pero no se descarta su extensión a otros campos de la industria que requieran características similares. This structure is designed especially for its application as support or frame of the mirrors of a solar collector, but its extension to other fields of the industry that require similar characteristics is not ruled out.

Realización preferente de la invención PREFERRED EMBODIMENT OF THE INVENTION
Para lograr una mayor comprensión de la invención a continuación se van a describir, según una realización preferente y analizando las características novedosas respecto a lo conocido en el estado de la técnica, la estructura que divulga la invención, en base a las figuras que se adjuntan.  In order to achieve a better understanding of the invention, the following description will describe, according to a preferred embodiment and analyzing the novel features with respect to the known in the state of the art, the structure that discloses the invention, based on the attached figures. .
(Nota: las figuras representan realizaciones alternativas para este tipo de estructuras, por lo tanto se han utilizado referencias diferentes en cada figura, pues aunque los elementos se llamen de la misma forma (barras, nudos...) no tienen porque ser de geometría igual y denominarlas con el mismo número podría dar lugar a confusión) (Note: the figures represent alternative realizations for this type of structures, therefore different references have been used in each figure, because although the elements are called in the same way (bars, knots ...) they do not have to be geometry equal and naming them with the same number could lead to confusion)
1. Configuración de la estructura y terminología 1. Configuration of the structure and terminology
Las figuras 1A y 1 B muestran los términos utilizados para describir las distintas partes de una estructura de un módulo de colector solar, de acuerdo con la realización preferente de la invención.  Figures 1A and 1B show the terms used to describe the different parts of a structure of a solar collector module, according to the preferred embodiment of the invention.
Se denominan nodos a los elementos de unión de varias barras (101), se denominan cordones aquellas barras que recorren la estructura de un extremo a otro longitudinalmente (104) y diagonales (102) aquellas que conectan un nodo (101) con otro siguiendo una línea diagonal.  The connecting elements of several rods (101) are called nodes, those rods that cross the structure from one end to the other longitudinally (104) and diagonal (102) are those that connect one node (101) to another following a diagonal line.
En la figura 1A se muestra además el brazo ( 03) que transmite el par del seguidor solar.  In Figure 1A is also shown the arm (03) that transmits the pair of the solar tracker.
2. Nodo con aletas en forma de caja En primer lugar y según muestra la figura 2, se observa un nodo (201) para conectar una serie de barras. El nodo (201) tiene unas aletas de sección rectangular (202) diseñadas para poder conectar otros miembros de la estructura, tales como cordones (203) u otras barras (204). El tamaño y la orientación de las aletas rectangulares (202) se pueden variar dependiendo del tamaño de los miembros a conectar y de la geometría deseada para la estructura. Para aumentar la resistencia, las aletas (202) se pueden reforzar internamente o incluso hacerlas sólidas. Los diferentes elementos de Ja estructura, incluyendo los cordones (203) y las barras (204), son preferiblemente tubulares, ya sean de sección circular, semicircular, rectangular, o de cualquier otra geometría. Dependiendo de la aplicación, se puede utilizar para alguno o todos los miembros de la estructura, formas de sección en "I", canales, formas sólidas, etcétera. 2. Node with box-shaped fins First and as shown in Figure 2, a node (201) is observed to connect a series of bars. The node (201) has fins of rectangular section (202) designed to be able to connect other members of the structure, such as cords (203) or other bars (204). The size and orientation of the rectangular fins (202) can be varied depending on the size of the members to be connected and the geometry desired for the structure. To increase the strength, the fins (202) can be reinforced internally or even made solid. The different elements of the structure, including the cords (203) and the bars (204), are preferably tubular, whether circular, semicircular, rectangular, or of any other geometry. Depending on the application, it can be used for some or all members of the structure, "I" section forms, channels, solid forms, and so on.
El nodo (201) de la realización preferente se configura para encajar sobre el borde exterior o periférico del cordón pasante (203).  The node (201) of the preferred embodiment is configured to fit over the outer or peripheral edge of the through cord (203).
La figura 3 ilustra una realización preferente del nodo (201), así como otras geometrías alternativas (301), (302) que tienen cajeadas aletas de secciones rectangulares (202). Cada aleta de sección rectangular (202) incluye dos paredes laterales y una pared (303) que une las paredes laterales, formando una forma de la caja. En las geometrías mostradas en la figura 3, las paredes laterales son paralelas, y las secciones cajeadas rectangulares, aunque otras geometrías serían posibles, incluyendo cajeados con paredes no paralelas, de diferentes tamaños o de diferentes formas. La figura 4 ilustra una posible técnica para unir las barras a las aletas en forma de caja. Los elementos de unión (401) utilizados pueden ser clavos, tornillos o cualquier equivalente conocido en el estado de la técnica.  Figure 3 illustrates a preferred embodiment of the node (201), as well as other alternative geometries (301), (302) having recessed fins of rectangular sections (202). Each tab rectangular section (202) includes two side walls and a wall (303) that joins the side walls, forming a shape of the box. In the geometries shown in Figure 3, the side walls are parallel, and the rectangular recessed sections, although other geometries would be possible, including recesses with non-parallel walls, of different sizes or of different shapes. Figure 4 illustrates a possible technique for joining the bars to the box-shaped fins. The connecting elements (401) used can be nails, screws or any equivalent known in the state of the art.
3. Diseños de las terminaciones de las barras  3. Designs of the terminations of the bars
Como se comentó en la descripción de la invención, el cajeado del nodo permite varias alternativas para la conexión de las barras a los nodos. As discussed in the description of the invention, the node cache allows several alternatives for the connection of the bars to the nodes.
Varios ejemplos de las diferentes alternativas del montaje de los puntales se muestran en las figuras 5-10.  Several examples of the different alternatives for mounting the struts are shown in Figures 5-10.
Cualquier combinación posible de geometría del conector y de la barra puede ser utilizada. Por ejemplo, las barras pueden ser de sección circular, cuadrada o rectangular, con los lados planos o de cualquier otra forma conveniente y no todas las barras de una estructura han de tener la misma geometría. Alternativamente, los puntales o parte final de las barras, pueden contener caras planas para lograr una conexión directa, por ejemplo en el caso de que tuviesen sección hexagonal u octogonal. En este caso, no sería necesario utilizar ningún conector adicional para conectar al nodo si la barra o el puntal están correctamente entallados. Por ejemplo, en la figura 5, el extremo final de la barra (501 ) está entallado y los lados cuentan con unos agujeros compatibles con la aleta en forma de caja (502) del nodo (503). En esta alternativa de unión, no se requiere ningún conector adicional. La figura 6 muestra otro ejemplo de conexión, esta vez utilizando un conector de placas planas. En esta alternativa, una o más placas planas (601 ) se fijan a las barras (602), por ejemplo utilizando elementos de unión (no mostrados) como remaches, tornillos, soldadura u otros medios. Las placas planas (601 ) son provistas de agujeros (603) u otros medios compatibles con la aleta (604) del nodo (605). Any possible combination of connector and bar geometry can be used. For example, the bars can be of circular, square or rectangular section, with the flat sides or in any other convenient way and not all the bars of a structure have to have the same geometry. Alternatively, the struts or final part of the bars may contain flat faces to achieve a direct connection, for example in case they had a hexagonal or octagonal section. In this case, it would not be necessary to use any additional connector to connect to the node if the bar or the strut is correctly fitted. For example, in Figure 5, the end of the bar (501) is notched and the sides have holes compatible with the box-shaped fin (502) of the node (503). In this joining alternative, no additional connector is required. Figure 6 shows another connection example, this time using a flat plate connector. In this alternative, one or more flat plates (601) are attached to the bars (602), for example using joining elements (not shown) such as rivets, screws, welding or other means. The flat plates (601) are provided with holes (603) or other means compatible with the fin (604) of the node (605).
La figura 7 muestra dos vistas de otro tipo de conector. En esta realización, uno o más conectores tubulares (701 ) se fijan a las barras (702). Los conectores (701 ) son barras rectangulares que se han cortado con una sierra de inglete al ángulo deseado. La configuración tubular hueca de los conectores (701 ) puede proporcionar fuerza y rigidez adicionales a la unión. Figure 7 shows two views of another type of connector. In this embodiment, one or more tubular connectors (701) are attached to the bars (702). The connectors (701) are rectangular bars that have been cut with a miter saw at the desired angle. The hollow tubular configuration of the connectors (701) can provide additional strength and rigidity to the joint.
La figura 8 muestra dos vistas de otro conector alternativo. En esta realización, una o más placas (801) están dobladas para alcanzar una unión compatible entre la barra (802) y el nodo (803). Las placas (801 ) se pueden hacer del metal estampado y pueden unirse interior o exteriormente a la barra (802). Esta realización es especialmente apropiada para realizar uniones entre largas barras a nodos.  Figure 8 shows two views of another alternative connector. In this embodiment, one or more plates (801) are bent to achieve a compatible connection between the bar (802) and the node (803). The plates (801) can be made of stamped metal and can be attached internally or externally to the bar (802). This embodiment is especially suitable for making connections between long rods to nodes.
La figura 9 muestra un conector de tipo cordón según otra realización. Este tipo de conectores son piezas estampadas y redondeadas que proporcionan mejor soporte a la estructura que los conectores (701), por ejemplo, debido a los ángulos a los que dirige la carga. En este caso uno o más conectores (901) se pueden fabricar por estampación en una forma compuesta y unir a las barras tal y como se unen a la barra (902) de la figura. Figure 9 shows a cord type connector according to another embodiment. This type of connectors are stamped and rounded pieces that provide better support to the structure than the connectors (701), for example, due to the angles to which the load directs. In this case one or more connectors (901) can be manufactured by stamping in a composite form and joining the bars as they are attached to the bar (902) of the figure.
La figura 10 muestra un conector (1001 ) de acuerdo con otra realización alternativa. El conector (1001 ) se puede fabricar por estampación de una pieza única de metal. Las bandas o correas (1002) se forman alternativamente en lados opuestos de una porción plana (1003) (como una espiral) y forman un receptáculo o conector que puede recibir a la barra (no mostrado). Mientras que el receptáculo se representa circular en la figura 10, otras formas pueden ser elegidas. El conector (1001) se puede unir a la barra de la estructura y también atar al nodo (no mostrado en la figura) utilizando elementos de unión en los agujeros (1004) o cualquier otro método de unión alternativo. Figure 10 shows a connector (1001) according to another alternative embodiment. The connector (1001) can be manufactured by stamping a single piece of metal. The bands or belts (1002) are formed alternately on opposite sides of a flat portion (1003) (like a spiral) and form a receptacle or connector that can receive the bar (not shown). While the receptacle is represented circular in Figure 10, other forms can be chosen. The connector (1001) can be attached to the bar of the structure and also tied to the node (not shown in the figure) using joining elements in the holes (1004) or any other alternative joining method.
4. Una estructura reforzada dentro de la estructura general  4. A reinforced structure within the overall structure
En la realización preferente de la invención se diseña la estructura para que concentre la carga principal en una localización determinada de la estructura, concretamente una esquina, de manera que transmita directamente la fuerza desde esa esquina atravesando toda la estructura, hasta salir por otra esquina.  In the preferred embodiment of the invention, the structure is designed so that it concentrates the main load in a determined location of the structure, specifically a corner, in such a way that it directly transmits the force from that corner through the entire structure, until it leaves another corner.
Las figuras 11A y 1B ilustran vistas oblicuas y superiores de una estructura en la cual se han reforzado ciertas barras (1101) para soportar cargas específicas, por ejemplo cargas acumuladas en un borde.  Figures 11A and 1B illustrate oblique and top views of a structure in which certain bars (1101) have been reinforced to support specific loads, for example loads accumulated on an edge.
Esta estrategia -cuya puesta en práctica es facilitada por el uso de las aletas en forma de caja y los extremos de las barras o de los puntales descritos anteriormente- que consiste en concentrar la fuerza sólo en unas barras ( 101) de la estructura, hace que dichas barras (1101) hayan de ser fuertemente reforzadas. Por consiguiente, esto reduce al mínimo los requisitos de carga de la mayoría de las barras de la estructura, permitiendo barras más pequeñas que requieren menos material. Al mismo tiempo, los miembros que soportan las cargas (1101) pueden ser reforzados fuertemente, creando una estructura total más rígida.  This strategy, whose implementation is facilitated by the use of the box-shaped fins and the ends of the bars or struts described above, consisting of concentrating the force only on a few bars (101) of the structure, makes that said bars (1101) have to be strongly reinforced. Consequently, this minimizes the load requirements of most of the bars in the structure, allowing smaller bars that require less material. At the same time, the members that bear the loads (1101) can be strongly reinforced, creating a more rigid overall structure.
5. Asimetría de la estructura  5. Asymmetry of the structure
La "estructura reforzada dentro de la estructura general" mostrada en las figuras 1 A y 11B es un ejemplo de una estructura asimétrica. En ese ejemplo, la estructura o armazón es simétrico a través un plano del centro, pero asimétrico sobre un plano longitudinal del centro. Algunas barras de las situadas en un lado del plano longitudinal del centro son mucho más grandes que las barras correspondientes al otro lado del plano longitudinal del centro para cumplir condiciones asimétricas de carga. Algunas barras pueden incluso no tener contrapartes en el lado opuesto.  The "reinforced structure within the overall structure" shown in Figures 1 A and 11B is an example of an asymmetric structure. In this example, the structure or framework is symmetrical through a plane of the center, but asymmetric on a longitudinal plane of the center. Some bars of those located on one side of the center longitudinal plane are much larger than the corresponding bars on the other side of the center longitudinal plane to meet asymmetric loading conditions. Some bars may even have no counterparts on the opposite side.
El plano longitudinal del centro se ilustra en la figura 12, mostrando una vista posterior y una vista en perspectiva. The longitudinal plane of the center is illustrated in Figure 12, showing a rear view and a perspective view.
Este concepto se podría magnificar dramáticamente, incluyendo asimetría extrema en la geometría de la base de la estructura y en una variación enorme del tamaño o la construcción de las barras. El resultado puede ser una estructura que se optimiza completamente en tres dimensiones para las cargas asimétricas soportadas por los bordes. Por consiguiente, la configuración óptima de la estructura es generalmente disimétrica, y puede ser extremadamente asimétrica, según las indicaciones de los ejemplos. En la figura 13, se muestran vistas simplificadas de las estructuras del colector de acuerdo con las distintas realizaciones de la invención. This concept could be magnified dramatically, including extreme asymmetry in the geometry of the base of the structure and in a huge variation of the size or construction of the bars. The result can be a structure that is optimized completely in three dimensions for the asymmetrical loads supported by the edges. Accordingly, the optimum configuration of the structure is generally asymmetric, and can be extremely asymmetric, according to the indications of the examples. In figure 13, simplified views of the collector structures according to the different embodiments of the invention are shown.
6. Cordón dividido en segmentos individuales  6. Cord divided into individual segments
Esta mejora consiste en dividir el cordón longitudinal que recorre la estructura en cordones menores. En un ejemplo de realización podríamos estar pasando de un cordón de 12 metros a cuatro cordones de 3 metros.  This improvement consists of dividing the longitudinal cord that runs through the structure in smaller cords. In an example of realization we could be going from a cord of 12 meters to four cords of 3 meters.
Las figuras 14A y 14B ilustran los nodos de una realización preferente (1401) y (1402) que utilizan estos segmentos reducidos.  Figures 14A and 14B illustrate the nodes of a preferred embodiment (1401) and (1402) using these reduced segments.
Además, y siguiendo lo explicado anteriormente, se trata de no hacer todos los elementos del cordón de una misma sección, si no que cada uno esté dimensionado de forma apropiada a la carga que vayan a soportar.  In addition, and following what has been explained above, it is a question of not making all the elements of the cord of the same section, but that each one is dimensioned in a way appropriate to the load that they will support.
La figura 15 muestra una vista de la superficie inferior de un módulo del colector de acuerdo con esta realización. En este ejemplo, un cordón del borde abarca tres secciones del cordón (1501), (1502), y (1503). Las tres secciones pueden tener diversos requisitos de la carga, tales que la sección (1502) del cordón del centro no necesita soportar la carga tan elevada como ésas experimentadas por las secciones (1501) y (1503). En ese caso, la sección (1502) del cordón del centro puede tener una sección más pequeña (por ejemplo un diámetro más pequeño), de modo que se ahorre material y disminuya el coste, con respecto a hacer la sección (1502) del cordón tan grande como las secciones (1501) y (1503). Otras geometrías de la estructura pueden dar lugar a diversas secciones del cordón, ya sean más grandes o más pequeñas. Los ejes de los elementos individuales del cordón pueden estar también desalineados (con respecto al eje longitudinal del colector) para maximizar la eficiencia estructural y para permitir la creación -de las geometrías antisimétricas, verdaderamente tridimensionales de la estructura. La figura 16 muestra una vista del colector, en el cual por lo menos un nodo se desplaza. Por ejemplo, el nodo de centro (1601) de un borde (1602) de abajo (1603) de la estructura se puede desplazar hacia arriba y hacia adentro, de modo que los nodos en ése borde (1602) del bastidor no sean coli- neales.  Figure 15 shows a view of the lower surface of a manifold module according to this embodiment. In this example, an edge cord comprises three cord sections (1501), (1502), and (1503). The three sections may have different load requirements, such that the section (1502) of the center cord does not need to bear the load as high as those experienced by the sections (1501) and (1503). In that case, the section (1502) of the center bead may have a smaller section (for example a smaller diameter), so that material is saved and the cost is decreased, with respect to making the cord section (1502) as large as sections (1501) and (1503). Other geometries of the structure can give rise to different sections of the cord, be they larger or smaller. The axes of the individual elements of the cord can also be misaligned (with respect to the longitudinal axis of the collector) to maximize the structural efficiency and to allow the creation of the truly three-dimensional antisymmetric geometries of the structure. Figure 16 shows a view of the collector, in which at least one node moves. For example, the center node (1601) of a bottom edge (1602) of the structure (1603) can be moved up and in, so that the nodes on that edge (1602) of the frame are not colli- neal
7. Eliminación de cordones En otra realización preferente, ciertos miembros de la estructura pueden ser quitados o eliminados completamente. La figura 17 muestra una vista oblicua de una estructura que ha omitido uno de los tradicionales cordones inferiores entre los nodos (.1701 ). La omisión de barras de la estructura es especialmente conveniente cuando los cordones han sido divididos y se utilizan nodos tales como los mostrados en las figuras 14A'y 14B. 7. Removal of laces In another preferred embodiment, certain members of the structure can be removed or removed completely. Figure 17 shows an oblique view of a structure that has omitted one of the traditional lower cords between the nodes (.1701). The omission of bars from the structure is especially convenient when the cords have been divided and nodes are used such as those shown in Figures 14A ' and 14B.
En una realización que omite cordones, la disposición de la estructura es tradicional, con nodos en las localizaciones habituales de los cordones que son colineales. La figura 18 ilustra una vista posterior de esta disposición.  In an embodiment that omits cords, the arrangement of the structure is traditional, with nodes in the usual locations of the cords that are collinear. Figure 18 illustrates a rear view of this arrangement.
Además, la omisión de algún cordón permite la colocación independiente de los nodos que, de otra manera, se podría haber visto determinada por la posición de los cordones. Los nodos y sus nodos asociados se pueden colocar en localizaciones estructuralmente más eficientes.  In addition, the omission of a cord allows the independent placement of the nodes that, otherwise, could have been determined by the position of the cords. The nodes and their associated nodes can be placed in structurally more efficient locations.
Por ejemplo, la figura 19 ¡lustra una vista posterior de un bastidor en el cual un nodo central (1901 ) de un borde (1902) inferior (1903) de una estructura se ha movido hacia arriba y hacia adentro de la estructura. Cabe observar que el nodo (1901) no está conectado por una barra con el borde (1902).  For example, Figure 19 illustrates a rear view of a frame in which a central node (1901) of a lower edge (1902) of a structure has moved up and into the structure. It should be noted that the node (1901) is not connected by a bar with the edge (1902).
8. Nodos de "longitud total"  8. "Total length" nodes
Se trata de utilizar un cordón de una gran longitud al que se le han unido las barras directamente sin necesidad de nodos. La figura 20 ilustra esa barra (2001), a la cual varios puntales (2002) se conectan. Las barras de la estructura se conectan directamente a este cordón aleteado por cualquier método, ya sean los descritos anteriormente u otros.  It is a matter of using a cord of great length to which the bars have been joined directly without the need for nodes. Figure 20 illustrates that bar (2001), to which several struts (2002) are connected. The bars of the structure are connected directly to this finned cord by any method, either those described above or others.
9. Nodo con sistema de unión independiente  9. Node with independent union system
La figura 21 ilustra otro ejemplo de montaje para realizar las conexiones entre los elementos de la estructura. En este ejemplo, las piezas (2101), (2102) se fijan a un cordón (2103), por ejemplo usando remaches, tornillos, pernos, soldadura,.. u otro medio apropiado. Este concepto del nodo crea múltiples sistemas de aletas paralelas para conectar los puntales (no mostrados) entre las aletas. Figure 21 illustrates another example of assembly to make the connections between the elements of the structure. In this example, parts (2101), (2102) are attached to a cord (2103), for example using rivets, screws, bolts, welding. . or other appropriate means. This concept of the node creates multiple parallel fin systems to connect the struts (not shown) between the fins.
10. Separación del espejo.  10. Separation of the mirror.
Existen una serie de elementos espaciadores que se pueden proporcionar para espaciar adecuadamente el espejo o los espejos de la estructura del módulo del colector. La figura 22 ilustra una vista oblicua de una parte de un módulo de colector. El espejo curvado (2201) se puede fabricar a partir de uno o más segmentos de vidrio aluminizado, de metal pulido o de otro material reflectivo adecuado. El espejoThere are a series of spacer elements that can be provided to adequately space the mirror or the mirrors of the collector module structure. Figure 22 illustrates an oblique view of a part of a manifold module. The curved mirror (2201) may be fabricated from one or more segments of aluminized glass, polished metal or other suitable reflective material. Mirror
(2201) puede tener la forma de un cilindro parabólico. La estructura puede tener aproximadamente la forma curvada del espejo (2201), pero los elementos de transi- ción pueden resolver las restantes diferencias de forma. (2201) may have the shape of a parabolic cylinder. The structure may have approximately the curved shape of the mirror (2201), but the transition elements can resolve the remaining shape differences.
En la realización preferente mostrada en la figura 22, los separadores (2202) se distribuyen a lo largo de un cordón (2203) en el extremo del colector. Los separadores In the preferred embodiment shown in Figure 22, the separators (2202) are distributed along a bead (2203) at the end of the manifold. The separators
(2202) se fijan al cordón (2203) usando remaches, pernos, tornillos, soldadura, o cualquier otro medio conveniente de fijación. (2202) are attached to the cord (2203) using rivets, bolts, screws, welding, or any other convenient means of attachment.
Igualmente, el espejo (2201) es fijado con los separadores (2202) por cualquier medio conveniente de fijación. Similarly, the mirror (2201) is fixed with the spacers (2202) by any convenient means of attachment.
Los separadores (2202) son fabricados preferiblemente por extrusión, pero se pueden fabricar por otros medios. Los separadores individuales colocados distanciados a lo largo del cordón (2203) y de otros miembros de la estructura, pueden reducir signi- ficativamente los requisitos de material para el módulo, respecto a otras técnicas para sostener el espejo (2201) en la posición adecuada.  The separators (2202) are preferably manufactured by extrusion, but can be manufactured by other means. The individual spacers positioned spaced along the cord 2203 and other members of the structure can significantly reduce the material requirements for the module with respect to other techniques for holding the mirror 2201 in the proper position.
Por ejemplo, una alternativa sería utilizar una correa muy larga recorriendo la longitud de la barra, solución que sería costosa por el hecho de utilizar mucho más material que el contenido en los separadores individuales (2202).  For example, an alternative would be to use a very long belt along the length of the bar, a solution that would be expensive due to the fact that it uses much more material than the content of the individual separators (2202).
Este sistema se diseña especialmente para su aplicación en estructuras o armazones para espejos de receptores o colectores solares, pero no se descarta su extensión a otros campos de la industria que requieran características similares. This system is designed especially for application in structures or frames for mirrors of receivers or solar collectors, but its extension to other fields of the industry that require similar characteristics is not ruled out.
