Description

“Sistema di supporto in particolare per moduli fotovoltaici" â € œSupport system in particular for photovoltaic modules "

Campo dell’invenzione Field of invention

La presente invenzione si riferisce ad un sistema di supporto in particolare per moduli fotovoltaici. The present invention refers to a support system in particular for photovoltaic modules.

Stato della tecnica State of the art

Sono noti diversi sistemi di fissaggio e montaggio per il sostegno di moduli fotovoltaici, uno del quali descritto nella domanda di brevetto EP1961977A. Various fastening and mounting systems for supporting photovoltaic modules are known, one of which is described in patent application EP1961977A.

Generalmente, nel caso di impianti su tetti a falda o terrazze, un sistema di montaggio à ̈ composto sostanzialmente da elementi allungati in alluminio o acciaio disposti al di sotto dei pannelli che fungono da binari, normalmente ancorati ad una struttura sottostante o direttamente al tetto. I moduli vengono prima appoggiati su detti elementi allungati ed in seguito bloccati tramite apposti elementi di fissaggio quali piastrine o elementi ad omega per bloccare testa a testa due moduli fotovoltaici attigui oppure a mezzo di elementi o a L rovesciata, nel caso di moduli di estremità. Questi elementi di fissaggio, a loro volta, sono collegati ai binari tramite bulloni e dadi filettati oppure viti speciali a disegno. Generally, in the case of systems on pitched roofs or terraces, an assembly system is substantially composed of elongated elements in aluminum or steel arranged below the panels that act as rails, normally anchored to an underlying structure or directly to the roof. The modules are first placed on said elongated elements and then blocked by means of fastening elements such as plates or omega elements to block two adjacent photovoltaic modules head to head or by means of elements or inverted L, in the case of end modules. These fastening elements, in turn, are connected to the tracks by means of threaded bolts and nuts or special screws according to drawings.

Se l’impianto à ̈, invece, destinato alla cosiddetta integrazione totale, allora detti elementi allungati sono ancorati direttamente alle parti portanti del tetto, quali puntoni, arcarecci o listelli di legno. Inoltre, il bloccaggio dei moduli fotovoltaici su detti binari viene realizzata non in singoli punti ma per tutta la lunghezza del bordo dei moduli, a mezzo di adatti profili estrusi farciti di guarnizioni a tenuta, in modo da evitare infiltrazioni di acqua piovana. If, on the other hand, the system is intended for so-called total integration, then these elongated elements are anchored directly to the load-bearing parts of the roof, such as struts, purlins or wooden strips. Furthermore, the blocking of the photovoltaic modules on said tracks is carried out not in single points but for the entire length of the edge of the modules, by means of suitable extruded profiles filled with airtight gaskets, in order to avoid infiltration of rainwater.

Per queste ragioni, in relazione al tipo di applicazione quali installazione su tetto con integrazione totale o parziale, oppure installazione al suolo, si richiede l'impiego di differenti tipologie di profili definenti detti elementi allungati. For these reasons, in relation to the type of application such as installation on the roof with total or partial integration, or installation on the ground, the use of different types of profiles defining said elongated elements is required.

Questo comporta notevoli problematiche sia in termini di stoccaggio dei materiali, sia in termini economici, poiché del materiale acquistato in eccesso per una tipologia di installazione non può essere impiegato fin quando non capiti un’altra medesima tipologia di installazione. This involves considerable problems both in terms of storage of materials and in economic terms, since the material purchased in excess for a type of installation cannot be used until another type of installation occurs.

Inoltre, cambiando la tipologia di elementi strutturali da impiegarsi a seconda delle necessità, il personale si trova disorientato e necessita di diverso tempo di addestramento. Furthermore, by changing the type of structural elements to be used according to needs, the staff find themselves disoriented and need a lot of training time.

Sommario dell'invenzione Summary of the invention

Scopo della presente invenzione à ̈ quello di fornire un elemento strutturale per un sistema di supporto in particolare per moduli fotovoltaici atto risolvere i suddetti problemi di installazione e stoccaggio di ferramenta dedicata al supporto di moduli fotovoltaici. The purpose of the present invention is to provide a structural element for a support system in particular for photovoltaic modules capable of solving the aforementioned problems of installation and storage of hardware dedicated to supporting photovoltaic modules.

E' oggetto della presente invenzione un elemento strutturale per sistema di supporto di moduli fotovoltaici che, conformemente alla rivendicazione 1 , presenta una sezione trasversale comprendente una prima parte conformata ad U e simmetrica rispetto un asse di simmetria, detta prima parte comprendendo una prima sede di guarnizioni in ciascuno dei gambi definenti detta U, essendo ciascuna sede disposta simmetricamente rispetto all’altra e rivolta verso l'esterno di detta U, essendo detta prima parte ad U conformata in modo da formare una slitta atta ad accogliere una testa di una vite con testa a martello. The object of the present invention is a structural element for a photovoltaic module support system which, according to claim 1, has a cross section comprising a first part shaped like a U and symmetrical with respect to an axis of symmetry, said first part comprising a first seat of gaskets in each of the legs defining said U, each seat being symmetrically arranged with respect to the other and facing the outside of said U, said first U-shaped part being shaped so as to form a slide suitable for receiving a head of a screw with hammer head.

Un ulteriore scopo dell’invenzione à ̈ quello di fornire un sistema di supporto di moduli fotovoltaici atto a risolvere i suddetti problemi. A further object of the invention is to provide a support system for photovoltaic modules suitable for solving the above problems.

Secondo un altro aspetto dell’invenzione la soluzione proposta consente di soddisfare tutte le principali applicazioni in campo fotovoltaico utilizzando solo una tipologia di profili di sostegno, tra loro intercambiabili ed adattabili, con un limitato numero di accessori adatti a risolvere il montaggio su ogni tetto o terreno, a tenuta all'acqua o meno. According to another aspect of the invention, the proposed solution allows to satisfy all the main applications in the photovoltaic field using only one type of support profiles, interchangeable and adaptable with each other, with a limited number of accessories suitable for solving the mounting on each roof. or ground, watertight or not.
