Description

Soporte para laminados fotovoltaicos.Support for photovoltaic laminates.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un soporte para laminados fotovoltaicos, en particular para laminados fotovoltaicos destinados a instalarse sobre cubiertas de edificios, donde la estanqueidad de la cubierta es determinante.The present invention relates to a support for photovoltaic laminates, in particular for laminates photovoltaic systems intended to be installed on roofs of buildings, where the tightness of the roof is decisive.

El objeto de la invención es conseguir un dispositivo que se fija a la cubierta en total ausencia de tornillos u otros elementos similares que deban perforar dicha cubierta, que además ofrece una mínima resistencia a las acciones del viento, con una excelente estabilidad, y que además se integra de forma óptima en la superficie de la cubierta, sin prácticamente repercusión alguna en la estética del edificio.The object of the invention is to achieve a device that is fixed to the cover in total absence of screws or other similar elements that must pierce said cover, which It also offers minimal resistance to wind actions, with excellent stability, and that also integrates optimally on the surface of the roof, with virtually no impact Some in the aesthetics of the building.

Antecedentes de la invenciónBackground of the invention

Como es sabido, los laminados fotovoltaicos están estructurados a base de una placa de vidrio que integra las células fotovoltaicas y sus complementos, configurando una placa de reducido espesor.As is known, photovoltaic laminates they are structured based on a glass plate that integrates the photovoltaic cells and their complements, configuring a plate of reduced thickness

Por obvia mejora en el rendimiento de los laminados fotovoltaicos, éstos debe adoptar una posición inclinada, para lo cual se utilizan habitualmente sistemas de sujeción basados en una perfilería con dispositivos de fijación mecánicos entre el laminado y el soporte, y con medios de fijación de dicho soporte a la cubierta, habitualmente tornillos, que requieren de perforaciones en dicha cubierta que rompen la estanqueidad de la misma, por lo que es necesario proceder tras la fijación al sellado de dichos orificios con resinas u otros productos adecuados.By obvious improvement in the performance of photovoltaic laminates, these should adopt an inclined position, for which base clamping systems are commonly used in a profile with mechanical fixing devices between the laminate and support, and with fixing means of said support to the cover, usually screws, that require perforations in said cover that break the tightness of it, so it is necessary to proceed after fixing them holes with resins or other suitable products.

Además los esfuerzos sufridos por la estructura tanto por la acción del viento como por las dilataciones y contracciones térmicas, dan lugar a problemas de cizalladura que con el tiempo pueden deteriorar el sellado de alguno de los puntos de fijación a la cubierta.In addition the efforts suffered by the structure as much for the action of the wind as for the expansions and thermal contractions, give rise to shear problems that with time can deteriorate the sealing of any of the points of fixing to the cover.

Tratando de obviar este problema son conocidos soportes para laminados fotovoltaicos consistentes en una especie de cazoleta de perfil angular, a cuya embocadura se acopla y fija el laminado fotovoltaico, generalmente por atornillamiento, estando dichas cubetas destinadas a ser lastradas, como por ejemplo con áridos, de manera que el peso de la cubeta mantenga ésta última estabilizada sobre la superficie de la cubierta.Trying to ignore this problem are known supports for photovoltaic laminates consisting of a kind of bowl of angular profile, to whose mouth it is attached and fixed the photovoltaic laminate, usually by screwing, being said buckets intended to be ballasted, such as with aggregates, so that the weight of the bucket keeps the latter stabilized on the surface of the roof.

Esta solución presenta una problemática con una doble vertiente, por un lado se alcanzan altas temperaturas en el interior de la cubeta, que lógicamente afectan negativamente al rendimiento del panel o laminado fotovoltaico, y por otro lado son de dimensiones pre-establecidas e invariables, de manera que los soportes previstos para un panel fotovoltaico de determinadas dimensiones, no son validos para paneles de diferentes dimensiones.This solution presents a problem with a double slope, on the one hand high temperatures are reached in the inside the bucket, which logically negatively affect the panel performance or photovoltaic laminate, and on the other hand they are of pre-established and invariable dimensions, of so that the supports provided for a photovoltaic panel of certain dimensions are not valid for different panels dimensions.

Descripción de la invenciónDescription of the invention

El soporte para laminados fotovoltaicos que la invención propone, perteneciendo al segundo grupo de los anteriormente citados, es decir siendo del tipo de los que se fijan a la cubierta por simple lastrado, resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en cada uno de los aspectos comentados.The support for photovoltaic laminates that the invention proposes, belonging to the second group of previously cited, that is to say of the type of those that are fixed to the cover by simple ballast, fully resolves satisfactory the aforementioned problem, in each of The commented aspects.

Para ello y de forma mas concreta, el soporte se materializa en una pareja de perfiles, preferentemente extrusionados en aluminio, ambos angulares, destinados a apoyar sobre la cubierta a través de una de sus ramas, que quedará en disposición horizontal o sensiblemente horizontal, siendo la otra rama de uno de ellos considerablemente mas alta que la del otro, y presentando su borde superior acodado hacia el perfil opuesto, determinando pestañas coplanarias o sensiblemente coplanarias, sobre las que ambos perfiles soportan al laminado fotovoltaico, que queda fijado a dichas pestañas mediante respectivas cintas adhesivas de doble cara.To do this and more specifically, the support is materializes in a pair of profiles, preferably extruded in aluminum, both angular, intended to rest on the roof through one of its branches, which will remain in horizontal arrangement or substantially horizontal, being the other branch of one of them considerably higher than the other, and presenting its edge upper layered to the opposite profile, determining tabs coplanar or substantially coplanar, on which both profiles support the photovoltaic laminate, which is fixed to said tabs by means of respective double adhesive tapes face.

La fijación entre perfiles angulares, además de realizarse a través de la propia placa o laminado fotovoltaico, se realiza con la colaboración de un lastre monopieza, consistente, por ejemplo, en una plancha de hormigón que apoya simultáneamente sobre la rama horizontal e inferior de ambos perfiles angulares.Fixing between angular profiles, in addition to be carried out through the photovoltaic plate itself or laminate, it performed with the collaboration of a single piece ballast, consistent, by example, on a concrete plate that simultaneously supports the horizontal and lower branch of both angular profiles.

De acuerdo con otra de las características de la invención se ha previsto que la rama superior del perfil angular mas alto adopte una disposición notablemente inclinada, formando un ángulo agudo con su rama horizontal, en orden a facilitar el acceso de la radiación solar al laminado fotovoltaico situado inmediatamente detrás.According to another of the characteristics of the invention is provided that the upper branch of the angular profile more tall adopt a remarkably inclined arrangement, forming a acute angle with its horizontal branch, in order to facilitate access from solar radiation to photovoltaic laminate located immediately behind.

Finalmente y de acuerdo con otra de las características de la invención, se ha previsto que la citada plancha constitutiva del lastre monopieza esté dotada inferiormente de ranuras transversales uniformemente distribuidas, en las que resultan acoplables selectivamente tetones emergentes de las ramas horizontales de ambos perfiles, de manera que dicho lastre no solo actúa como tal en el contexto general de la estructura, sino que además actúa como distanciador entre los perfiles angulares.Finally and according to another of the characteristics of the invention, it is provided that said single piece ballast plate is provided with lower of uniformly distributed transverse grooves, in which pop-up branches are selectively attachable horizontal of both profiles, so that said ballast not only acts as such in the general context of the structure, but that It also acts as a spacer between the angular profiles.

Se consigue de esta manera una estructura sumamente simple, de fácil montaje, que se mantiene inmovilizada con respecto al suelo en ausencia de tornillos y otros elementos similares de fijación, y que al quedar abierta por sus extremos asegura una óptima ventilación para el laminado fotovoltaico que soporta.In this way a structure is achieved extremely simple, easy to assemble, which remains immobilized with with respect to the ground in the absence of screws and other elements similar fixing, and that when left open at its ends ensures optimum ventilation for photovoltaic laminate that supports
