PLACA METÁLICA PARA RECUBRIMIENTOSMETAL PLATE FOR COATINGS

CAMPO TÉCNICO DE LA INVENCIÓNTECHNICAL FIELD OF THE INVENTION

La presente invención se engloba en el campo de las placas metálicas para recubrimientos en construcción de edificaciones o similares, en concreto las placas metálicas ensamblables dispuestas una a continuación de la otra susceptibles de recibir soportes para otros elementos como paneles solares y similares. The present invention is included in the field of metal plates for coatings in the construction of buildings or similar, specifically assembleable metal plates arranged one after the other capable of receiving supports for other elements such as solar panels and the like.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Una de las aplicaciones más habituales en las técnicas actuales de construcción es la utilización de recubrimientos de carácter autoportante, en especial para el recubrimiento de fachadas horizontales o verticales en edificaciones del tipo industrial, símil a nave logística, supermercados, centros comerciales, polideportivos, etc., para lo que se utilizan placas metálicas de productos y materiales adecuados al uso, que junto con una unión simulada y un acabado de calidad ofrecen las características necesarias de aislamiento y cerramiento a las incidencias meteorológicas, como la lluvia, viento o la nieve, así como también aislamiento térmico y acústico desde el exterior. Se puede aplicar en fachada orientando la chapa en vertical, bien en horizontal o incluso con ciertos grados angulares. One of the most common applications in current construction techniques is the use of self-supporting coatings, especially for covering horizontal or vertical facades in industrial buildings, similar to logistics warehouses, supermarkets, shopping centers, sports centers, etc. ., for which metal plates of products and materials suitable for use are used, which together with a simulated union and a quality finish offer the necessary insulation and enclosure characteristics to meteorological incidents, such as rain, wind or snow, as well as thermal and acoustic insulation from the outside. It can be applied on a façade by orienting the sheet vertically, horizontally or even with certain angular degrees.

Uno de los retos de las placas metálicas es que tengan la configuración adecuada para el recubrimiento que deban realizar, tanto a nivel estético como funcional, así como que garanticen un ensamblaje entre placas contiguas que sea sencillo y estanco, de manera que proporciona una continuidad al recubrimiento aun estando formado por placas unitarias ensambladas. One of the challenges of metal plates is that they have the appropriate configuration for the coating that they must make, both aesthetically and functionally, as well as that they guarantee an assembly between adjacent plates that is simple and watertight, in a way that provides continuity to the coating even though it is formed by assembled unitary plates.

Es habitual disponer en los tejados de los edificios placas solares de tipo fotovoltaico, térmico o mixtas, las cuales van colocadas mediante soportes fijados a las placas para recubrimiento. Normalmente, la sujeción de los soportes de las placas solares implica el taladrado de las placas para recubrimiento, con la consiguiente pérdida de continuidad y, por lo tanto, de características estructurales, así como de impermeabilidad, al crear huecos permeables a los elementos como agua, nieve, viento, etc. It is common to have photovoltaic, thermal or mixed solar panels on the roofs of buildings, which are placed using supports fixed to the covering plates. Normally, fastening the solar panel supports involves drilling the plates for coating, with the consequent loss of continuity and, therefore, of structural characteristics, as well as impermeability, by creating gaps permeable to the elements such as water. , snow, wind, etc.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

La presente invención queda establecida y caracterizada en la reivindicación independiente, mientras que las reivindicaciones dependientes describen otras características de la misma. The present invention is established and characterized in the independent claim, while the dependent claims describe other characteristics thereof.

El objeto de la invención es una placa metálica para recubrimientos. El problema técnico a resolver es configurar la placa metálica para que sea una alternativa válida a lo conocido, que proporcione un anclaje para soportes de placas solares evitando los problemas de debilitamiento estructural y pérdida de estanqueidad que ocasionan los taladros u orificios pasantes. The object of the invention is a metal plate for coatings. The technical problem to be solved is to configure the metal plate so that it is a valid alternative to what is known, which provides an anchor for solar panel supports, avoiding the problems of structural weakening and loss of tightness caused by drills or through holes.

A la vista de lo anteriormente enunciado, la presente invención se refiere a una placa metálica para recubrimientos. Con “placa” se quiere referir a cualquier elemento laminar cuyas dimensiones de altura y anchura son mucho mayores que el espesor, siendo esta dimensión mucho menor o despreciable frente a las otras. In view of the above, the present invention refers to a metal plate for coatings. By “plate” we mean any laminar element whose height and width dimensions are much greater than the thickness, this dimension being much smaller or negligible compared to the others.

La placa metálica comprende una primera protuberancia, la cual a su vez comprende una primera pared inclinada y una segunda pared inclinada, ambas conectadas en su extremo libre superior por un primer tramo de enlace; un primer tramo curvo queda conectado en el extremo libre inferior de la primera pared inclinada; un segundo tramo curvo queda conectado en el extremo libre inferior de la segunda pared inclinada; en el extremo libre de cada tramo curvo, primero y segundo, queda conectada una pared de base orientada hacia el exterior de la primera protuberancia; el primer tramo curvo y el segundo tramo curvo quedan orientados con su curvatura hacia el interior de la primera protuberancia, a modo de gargantas cuya abertura queda orientada hacia el exterior de la primera protuberancia. The metal plate comprises a first protuberance, which in turn comprises a first inclined wall and a second inclined wall, both connected at its upper free end by a first link section; a first curved section is connected to the lower free end of the first inclined wall; a second curved section is connected to the lower free end of the second inclined wall; At the free end of each first and second curved section, a base wall facing the outside of the first protuberance is connected; The first curved section and the second curved section are oriented with their curvature towards the interior of the first protuberance, like grooves whose opening is oriented towards the outside of the first protuberance.

Con “hacia el exterior” se quiere decir en el sentido de alejarse del elemento al que se hace referencia; de manera opuesta, “hacia el interior” quiere decir hacia dentro del elemento. By “outwards” it is meant in the sense of moving away from the element being referred to; In the opposite way, “towards the interior” means towards the inside of the element.

Las denominaciones espaciales “inclinada”, “inferior”, “superior”, “horizontal”, “vertical”, “ascendente” y similares se refieren a las referencias espaciales habituales cuando la placa metálica está en una posición final montada a modo de recubrimiento sobre una superficie horizontal o ligeramente inclinada, del mismo modo a como se muestran en las figuras de la realización mostrada aquí más adelante, no siendo limitantes y utilizándose para una mejor explicación de la invención. The spatial designations “inclined”, “lower”, “upper”, “horizontal”, “vertical”, “ascending” and similar refer to the usual spatial references when the metal plate is in a final position mounted as a covering on a horizontal or slightly inclined surface, in the same way as shown in the figures of the embodiment shown here below, not being limiting and being used for a better explanation of the invention.

Las gargantas ocasionadas por el primer tramo curvo y el segundo tramo curvo proporcionan una especie de “nervios” adecuados para alojar soportes de placas solares, evitando la perforación o taladrado que origina orificios pasantes, con lo que se garantiza la integridad estructural e impermeabilidad que proporciona la continuidad de la placa metálica. The grooves caused by the first curved section and the second curved section provide a type of “nerves” suitable for housing solar panel supports, avoiding drilling or drilling that causes through holes, thereby guaranteeing the structural integrity and impermeability provided by it. the continuity of the metal plate.

La placa metálica tiene entonces la propiedad de autoportante, pues la estabilidad de cada placa metálica unitaria, junto con las que se ensamblan conjuntamente, otorga un carácter resistivo propio sin ayuda de una estructura añadida. The metal plate then has the property of being self-supporting, since the stability of each unitary metal plate, together with those that are assembled together, gives its own resistive character without the help of an added structure.

La instalación de los soportes es sencilla, dado que se evita el paso de elementos, como tornillos, por orificios, que implica su enhebrado y posterior fijación. The installation of the supports is simple, since it avoids the passage of elements, such as screws, through holes, which implies threading and subsequent fixing.

Otras ventajas relacionadas con características de las reivindicaciones dependientes se citan aquí debajo en la exposición detallada. Other advantages related to features of the dependent claims are cited below in the detailed discussion.

The characteristics mentioned are the minimum necessary to fulfill the object of the invention, referring to the first protuberance (1) and the grooves formed therein. It can be completed with the characteristics mentioned below to configure a plate like the one shown in Figure 1, with the inclined walls referred to in Figures 2 to 5, suitable due to its rigidity for a multitude of applications: it also includes a second protuberance (2). which in turn comprises a third inclined wall (2.1) and a fourth inclined wall (2.2), both connected at its upper free end by a second link section (2.3); It also comprises a third protrusion (3) which in turn comprises a fifth inclined wall (3.1) and a sixth inclined wall (3.2), both connected at its upper free end by a third link section (3.3); It also comprises a fourth protuberance (4) which in turn comprises a seventh inclined wall (4.1) and an eighth inclined wall (4.2), both connected at its upper free end by a fourth link section (4.3); It also comprises a fifth protuberance (5) which in turn comprises a ninth inclined wall (5.1) and a tenth inclined wall (5.2), both connected at its upper free end by a fifth link section (5.3); The plate is constituted with the fourth protuberance (4), the third protuberance (3), the first protuberance (1), the third protuberance (3), the second protuberance (2), the third protuberance (3) being arranged consecutively. , the first protuberance (1), the third protuberance (3) and the fifth protuberance (5); the lower free end of the eighth inclined wall (4.2) and that of the adjacent fifth inclined wall (3.1) are connected by a base wall (6); the lower free end of the sixth inclined wall (3.2) and that of the first curved section (1.4) are connected by a base wall (6); the lower free end of the second curved section (1.5) and that of the adjacent fifth inclined wall (3.1) are connected by a base wall (6); the lower free end of the sixth inclined wall (3.2) and that of the adjacent third inclined wall (2.1) are connected by a base wall (6); the lower free end of the fourth inclined wall (2.2) and that of the adjacent fifth inclined wall (3.1) are connected by a base wall (6); The lower free end of the sixth inclined wall (3.2) and that of the adjacent ninth inclined wall (5.1) are connected by a base wall (6).

Un opción, figura 4, es que la séptima pared inclinada (4.1) es de menor longitud que la octava pared inclinada (4.2); la quinta protuberancia (5) presenta un entrante (5.4), figura 5, en la confluencia de la novena pared inclinada (5.1) y el quinto tramo de enlace (5.3), y la décima pared inclinada (5.2) queda conectada en su extremo libre inferior a una pestaña (5.5) orientada hacia el exterior de la placa. Estos detalles ayudan a un mejor acoplamiento entre placas contiguas. Además, el entrante (5.4) permite el alojamiento de elementos tubulares, como cables eléctricos o tuberías de conducción de fluidos. One option, Figure 4, is that the seventh inclined wall (4.1) is shorter than the eighth inclined wall (4.2); The fifth protuberance (5) has an indentation (5.4), Figure 5, at the confluence of the ninth inclined wall (5.1) and the fifth connecting section (5.3), and the tenth inclined wall (5.2) is connected at its end. free bottom to a tab (5.5) facing the outside of the plate. These details help better coupling between adjacent plates. Furthermore, the recess (5.4) allows the accommodation of tubular elements, such as electrical cables or fluid conduction pipes.

Otra opción es que la primera pared inclinada (1.1) con el primer tramo curvo (1.4) y la segunda pared inclinada (1.2) con el segundo tramo curvo (1.5) quedan dispuestos de manera simétrica entre sí, figura 2. Análogamente, la tercera pared inclinada (2.1) y la cuarta pared inclinada (2.2) pueden quedar dispuestas de manera simétrica entre sí, figura 3; también, la quinta pared inclinada (3.1) y la sexta pared inclinada (3.2) pueden quedar dispuestas de manera simétrica entre sí, figura 3. La disposición simétrica de configuraciones proporciona un equilibrio en la configuración estructural, lo que conlleva un reparto igualmente simétrico de las tensiones que recibe la placa. Another option is that the first inclined wall (1.1) with the first curved section (1.4) and the second inclined wall (1.2) with the second curved section (1.5) are arranged symmetrically with each other, Figure 2. Similarly, the third inclined wall (2.1) and the fourth inclined wall (2.2) can be arranged symmetrically with each other, figure 3; Also, the fifth inclined wall (3.1) and the sixth inclined wall (3.2) can be arranged symmetrically with each other, Figure 3. The symmetrical arrangement of configurations provides a balance in the structural configuration, which entails an equally symmetrical distribution of the stresses received by the plate.

Otra opción es que las sucesivas paredes de base (6) quedan dispuestas horizontales y en el mismo plano, figuras 1, 6 y 7; los primeros tramos de enlace (1.3), el segundo tramo de enlace (2.3), el cuarto tramo de enlace (4.3) y el quinto tramo de enlace (5.3) quedan dispuestos horizontales y en el mismo plano, figura 1; los terceros tramos de enlace (3.3) quedan dispuestos horizontales y en el mismo plano, figura 1. La horizontalidad y coplanaridad aportan planos de apoyo de toda la dimensión de la placa, tanto en su plano superior como inferior, con lo que proporcionan un apoyo horizontal y estable y permiten igualmente que un elemento, una lámina aislante por ejemplo, se apoye de manera horizontal y estable sobre la placa. Another option is that the successive base walls (6) are arranged horizontally and in the same plane, figures 1, 6 and 7; the first link sections (1.3), the second link section (2.3), the fourth link section (4.3) and the fifth link section (5.3) are arranged horizontally and in the same plane, Figure 1; The third link sections (3.3) are arranged horizontally and in the same plane, figure 1. The horizontality and coplanarity provide support planes for the entire dimension of the plate, both in its upper and lower plane, thereby providing support horizontal and stable and also allow an element, an insulating sheet for example, to rest horizontally and stably on the plate.

En la figura 6 se muestra el acoplamiento de placas contiguas, sin más que superponer la cuarta protuberancia (4) de una placa sobre la quinta protuberancia (5) de la placa contigua, no hay límite a cuántas placas metálicas se pueden disponer una detrás de otra, sin más que repetir el modo de ensamblaje expuesto. Figure 6 shows the coupling of adjacent plates, simply by superimposing the fourth protuberance (4) of a plate on the fifth protuberance (5) of the adjacent plate, there is no limit to how many metal plates can be arranged one behind another, without more than repeating the exposed assembly method.

En la figura 7 se muestra un soporte (100) adecuado para montarse en la primera protuberancia (1) sin utilizar taladros, orificios pasantes o similares, sin más que encastrase en las gargantas formadas por el primer tramo curvo (1.4) y el segundo tramo curvo (1.5). El soporte (100) mostrado es un ejemplo ilustrativo, consistente en dos mitades que pueden separarse entre sí para abrazar la primera protuberancia (1) y con configuraciones correspondientes a las gargantas que quedan encastradas en las mismas, de manera que el soporte (100) queda sujeto de manera firme, pues hay que notar que la representación es una vista de perfil y la placa se extiende cierta longitud, como se aprecia en la figura 1, con lo que la sujeción es a lo largo de esa longitud, lo que proporciona una buena sujeción del soporte (100). Figure 7 shows a support (100) suitable for mounting on the first protrusion (1) without using drills, through holes or similar, simply fitting into the grooves formed by the first curved section (1.4) and the second section. curved (1.5). The support (100) shown is an illustrative example, consisting of two halves that can be separated from each other to embrace the first protuberance (1) and with configurations corresponding to the grooves that are embedded therein, so that the support (100) is firmly attached, as it should be noted that the representation is a profile view and the plate extends a certain length, as seen in Figure 1, so the attachment is along that length, which provides a good hold of the support (100).
