DESCRIZIONE DESCRIPTION
“STAFFA UNIVERSALE PER IL FISSAGGIO DI PANNELLI FOTOVOLTAICI”. “UNIVERSAL BRACKET FOR FIXING PHOTOVOLTAIC PANELS”.
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente domanda di brevetto per modello di utilità ha per oggetto una staffa universale per eseguire, al di sopra delle coperture dei tetti, il fissaggio di pannelli fotovoltaici in assetto orizzontale. The present utility model patent application relates to a universal bracket for fixing photovoltaic panels in a horizontal position above the roof coverings.
Come è noto l’utilizzo dei pannelli fotovoltaici ai fini del risparmio energetico sta conoscendo ultimamente una notevole diffusione, anche e soprattutto nell’ambito dei capannoni destinati ad attività industriali o artigianali. As is well known, the use of photovoltaic panels for the purpose of energy saving has recently been experiencing a considerable spread, also and above all in the context of warehouses for industrial or craft activities.
In effetti in quest’ultimo genere di edifici è previsto che le coperture dei tetti siano realizzati con pannelli grecati dotati di una struttura a sandwich, in quanto composti da uno spesso strato portante in schiuma poliuretanica e da un sovrastante mantello di rivestimento in lamiera. In fact, in the latter type of buildings it is expected that the roof coverings are made with corrugated panels with a sandwich structure, as they are composed of a thick supporting layer of polyurethane foam and an overlying sheet metal covering.
Attualmente sul mercato sono reperibili alcune versioni alternative di tali pannelli grecati, tra loro differenziate in relazione al profilo adottato nell’ambito della loro anzidetta superficie metallica di rivestimento. Currently on the market there are some alternative versions of these corrugated panels, differentiated from each other in relation to the profile adopted in the context of their aforementioned metal coating surface.
Se è vero infatti che tutti i pannelli grecati si caratterizzano per il fatto di presentare superiormente una pluralità di vistose costole in rilievo, dotate normalmente di una sezione trasversale trapezoidale, è altrettanto noto che tali pannelli non siano realizzati in una versione “unificata”, ma in alcune versioni alternative tra loro diversificate proprio in ragione del diverso profilo adottato in corrispondenza delle loro rispettive costole in rilievo. If it is true that all the corrugated panels are characterized by the fact that they have a plurality of prominent raised ribs at the top, normally equipped with a trapezoidal cross-section, it is also known that these panels are not made in a "unified" version, but in some alternative versions diversified from each other precisely because of the different profile adopted in correspondence with their respective ribs in relief.
Fermo restando che le costole previste negli attuali modelli di pannelli grecati presentano sostanzialmente una medesima altezza, ciò che le rende differenti è la larghezza adottata e l’inclinazione delle rispettive pareti laterali. It being understood that the ribs provided in the current models of corrugated panels have substantially the same height, what makes them different is the width adopted and the inclination of the respective side walls.
Va detto peraltro che, in altri casi, le coperture dei tetti sono tuttora realizzate con tradizionali solai piani, del tutto privi cioè delle anzidette costole in rilievo. However, it must be said that, in other cases, the roofs are still made with traditional flat floors, that is, completely devoid of the aforementioned raised ribs.
A prescindere dalla specifica copertura di volta in volta adottata, il montaggio dei pannelli fotovoltaici al di sopra di un tetto può avvenire sulla base di due tecnologie alternative. Regardless of the specific roofing adopted from time to time, the mounting of photovoltaic panels above a roof can take place on the basis of two alternative technologies.
In una prima ipotesi è prevista la realizzazione, al di sopra delle coperture anzidette, una vera e propria orditura di barre tubolari, preposta per l’appunto al supporto e all’ancoraggio dei pannelli anzidetti. In a first hypothesis, above the aforementioned roofs, a real warping of tubular bars is envisaged, in charge of supporting and anchoring the aforementioned panels.
Una tecnologia alternativa è invece quella che prevede il montaggio, al di sopra della rispettiva copertura di un tetto, di una pluralità di robuste staffe dalle quali aggettano verso l’alto rispettivi steli filettati ad asse verticale. An alternative technology, on the other hand, is that which involves the assembly, above the respective roof covering, of a plurality of sturdy brackets from which their respective threaded stems with vertical axis project upwards.
Su questi steli filettati debbono essere avvitate alcune barre tubolari, a loro volta destinate a supportare effettivamente rispettivi sovrastanti pannelli fotovoltaici. On these threaded stems some tubular bars must be screwed, in turn intended to effectively support respective overlying photovoltaic panels.
Quest’ultima tecnologia prevede peraltro che i bordi ravvicinati di due pannelli fotovoltaici consecutivi si dispongano, da parti opposte, ai due lati di ciascuna delle anzidette piastre di fissaggio, in maniera tale che lo stelo filettato di quest’ultima possa sporgere verso l’alto in una posizione ad essi intermedia. The latter technology also provides that the close edges of two consecutive photovoltaic panels are arranged, on opposite sides, on the two sides of each of the aforementioned fixing plates, so that the threaded stem of the latter can protrude upwards. in an intermediate position to them.
A questo punto è previsto che sullo stelo medesimo sia calato un piastrino, opportunamente dotato di un foro passante, atto ad attestarsi dall’alto verso il basso contro la superficie superiore dei due anzidetti pannelli fotovoltaici affiancati, sì da impedire loro qualsiasi fortuito sollevamento. At this point, it is expected that a plate is lowered onto the stem itself, suitably equipped with a through hole, able to abut from top to bottom against the upper surface of the two aforementioned photovoltaic panels side by side, so as to prevent them from any accidental lifting.
Le attuali staffe destinate ad essere montate su coperture perfettamente piane consistono in realtà in semplici piastre, preferibilmente dotate di una imbutitura centrale, aggettante verso l’alto, in corrispondenza della quale è previsto il foro entro cui s’infila, dal basso verso l’alto, il rispettivo stelo filettato. The current brackets intended to be mounted on perfectly flat roofs actually consist of simple plates, preferably equipped with a central drawing, projecting upwards, in correspondence with which the hole into which it is inserted is foreseen, from the bottom towards the high, the respective threaded rod.
In presenza di coperture formate con pannelli grecati è invece prevista l’adozione di staffe atte ad essere montate “a cavallo” di ciascuna costola di tali pannelli, vale a dire in corrispondenza dei punti in cui gli stessi presentano il massimo spessore e dunque la maggiore resistenza. In the presence of roofs formed with corrugated panels, on the other hand, brackets are envisaged to be mounted "astride" each rib of these panels, that is to say in correspondence with the points where they have the greatest thickness and therefore the greatest resistence.
Per tale ragione le staffe destinate a cooperare con tali pannelli grecati adottano un profilo sostanzialmente ad “U” capovolta che consente loro, per l’appunto, di sovrapporsi esattamente alle costole del pannello medesimo. For this reason, the brackets intended to cooperate with these corrugated panels adopt a substantially inverted "U" profile that allows them, precisely, to overlap exactly the ribs of the panel itself.
Perché si produca tale condizione è naturalmente necessario che il profilo di ciascuna di tali staffe sia perfettamente corrispondente a quello della rispettiva costola di destinazione. For this condition to occur, it is naturally necessary that the profile of each of these brackets corresponds perfectly to that of the respective target rib.
Considerando allora che a tutt’oggi sono presenti sul mercato almeno due versioni di pannelli grecati, l’uno con costole di maggiore larghezza, l’altro con costole di minore larghezza, risulta evidente come anche le staffe ad essi rispettivamente destinate debbano essere realizzate in due differenti versioni, ciascuna delle quali in grado di adattarsi ad una sola delle anzidette tipologie di costole. Considering then that at least two versions of corrugated panels are currently on the market, one with wider ribs, the other with narrower ribs, it is clear that the brackets respectively intended for them must also be made in two different versions, each of which can be adapted to only one of the aforementioned types of ribs.
Sulla base di tali premesse è facile comprendere come un installatore di pannelli fotovoltaici debba avere sempre a disposizione una dotazione delle tre anzidette tipologie di piastre di supporto, dovendo ipotizzare di poter essere chiamato ad operare indifferentemente su solai di copertura dotati superiormente di un profilo piano, su pannelli di copertura grecati con costole di notevole larghezza o su pannelli di copertura grecati con costole di ridotta larghezza. On the basis of these premises, it is easy to understand how an installer of photovoltaic panels must always have at his disposal a supply of the three aforementioned types of support plates, having to assume that he can be called upon to operate indifferently on roofing floors equipped at the top with a flat profile, on corrugated roof panels with ribs of considerable width or on corrugated roof panels with ribs of reduced width.
Scopo specifico della presente invenzione è dunque quello di realizzare, per la prima volta, una staffa universale, capace cioè di essere convenientemente ed indifferentemente fissata su pannelli di copertura delle tre anzidette tipologie. The specific aim of the present invention is therefore to provide, for the first time, a universal bracket, that is capable of being conveniently and indifferently fixed on the covering panels of the three aforementioned types.
Ebbene va detto che la staffa secondo il trovato, che reca una forma in pianta sostanzialmente quadrata, si avvale di una particolare struttura concava, sostanzialmente a croce, nell’ambito della quale i due rami della croce sono rappresentati da due profili rettilinei concavi, aventi entrambi sezione sostanzialmente trapezoidale, ma dotati di una differente inclinazione in corrispondenza dei rispettivi fianchi laterali e dunque di una differente ampiezza in corrispondenza della loro cavità interna. Well it should be said that the bracket according to the invention, which has a substantially square shape, makes use of a particular concave structure, substantially cross, in which the two branches of the cross are represented by two concave rectilinear profiles, having both substantially trapezoidal section, but provided with a different inclination in correspondence with the respective lateral sides and therefore with a different amplitude in correspondence with their internal cavity.
In particolare uno di tali profili rettilinei concavi adotta una sezione trapezoidale che gli consente di disporsi perfettamente “a cavallo” delle costole di una prima delle più diffuse tipologie di pannelli grecati utilizzati nella copertura di un tetto. In particular, one of these concave rectilinear profiles adopts a trapezoidal section that allows it to be positioned perfectly "astride" the ribs of a first of the most common types of corrugated panels used in roofing.
Analogamente il secondo di tali profili rettilinei concavi adotta invece una sezione trapezoidale atta a consentirgli di disporsi perfettamente “a cavallo” delle costole di una seconda delle due più diffuse tipologie di pannelli grecati. Similarly, the second of these concave rectilinear profiles instead adopts a trapezoidal section which allows it to be positioned perfectly "astride" the ribs of a second of the two most common types of corrugated panels.
Alla base di una simile struttura concava a croce, ed in posizione intermedia tra i quattro bracci della stessa, sono peraltro previsti quattro piastrini forati centralmente. At the base of such a concave cross-shaped structure, and in an intermediate position between the four arms of the same, there are also four centrally perforated plates.
A tale riguardo si precisa altresì che su questi quattro piastrini “angolari”, così come del resto in corrispondenza della parete superiore dei due rami perpendicolari della suddetta struttura concava a croce, sono eseguiti alcuni fori passanti destinati al consentire il passaggio, dall’alto verso il basso, di rispettive viti di fissaggio contro i sottostanti rispettivi pannelli di copertura di un tetto. In this regard, it is also specified that on these four "corner" plates, as well as in correspondence with the upper wall of the two perpendicular branches of the aforementioned concave cross structure, some through holes are made to allow passage from top to the bottom, of respective fixing screws against the underlying respective covering panels of a roof.
Ebbene, alla luce di questa prima sommaria descrizione del trovato, è facile comprendere come la staffa secondo il trovato possa essere correttamente fissata al di sopra di ognuna delle tre più diffuse tipologie di pannelli destinati a realizzare la copertura di un tetto. Well, in the light of this first brief description of the invention, it is easy to understand how the bracket according to the invention can be correctly fixed above each of the three most common types of panels intended to cover a roof.
In presenza, infatti, di coperture perfettamente piane, il montaggio della staffa medesima prevede che la stessa sia attestata al di sopra di tale rivestimento in corrispondenza dei suoi quattro piastrini angolari e fissata con rispettive viti infilate dall’alto verso il basso attraverso gli appositi fori di questi ultimi. In fact, in the presence of perfectly flat roofs, the mounting of the bracket itself requires that it is abutment above this coating in correspondence with its four corner plates and fixed with respective screws inserted from top to bottom through the appropriate holes of the latter.
L’accoppiamento della medesima piastra alle costole di eventuali pannelli grecati viene invece favorito dalla presenza dei suoi anzidetti profili trapezoidali cavi, con il solo accorgimento di selezionare, di volta in volta, quello dei due che si rileva effettivamente conforme con la specifica sezione della sottostante costola di fissaggio. The coupling of the same plate to the ribs of any corrugated panels is instead favored by the presence of its aforementioned hollow trapezoidal profiles, with the sole expedient of selecting, from time to time, the one of the two that actually conforms to the specific section of the underlying fixing rib.
Si può dire altrimenti che l’operatore che abbia a disposizione un esemplare del trovato sarà in grado di selezionare di volta in volta, per il tramite di una semplice rotazione di 90° dell’intera staffa, quello dei suoi due profili trapezoidali concavi in grado di adattarsi perfettamente alla specifica sezione della costole di destinazione. It can be said otherwise that the operator who has at his disposal an example of the invention will be able to select from time to time, by means of a simple 90 ° rotation of the entire bracket, that of his two concave trapezoidal profiles capable of to adapt perfectly to the specific section of the target ribs.
Una volta realizzato un simile corretto accoppiamento “a maschio e femmina” tra la staffa in questione e la sottostante costola del rispettivo pannello grecato, si potrà prevedere al loro reciproco e definitivo fissaggio per il tramite di viti ad asse verticale infilate dall’alto verso il basso attraverso quegli anzidetti fori passanti previsti in corrispondenza della parete orizzontale superiore di entrambi i profili trapezoidali. Once a similar correct "male and female" coupling has been made between the bracket in question and the underlying rib of the respective corrugated panel, their mutual and definitive fixing can be envisaged by means of vertical axis screws inserted from the top towards the through those aforementioned through holes provided in correspondence with the upper horizontal wall of both trapezoidal profiles.
Al fine di garantire alla staffa secondo il trovato un’ancora maggiore stabilità di fissaggio è previsto che la stessa possa presentare ulteriori fori passanti (sempre destinati al passaggio di rispettive viti) anche in corrispondenza delle sponde laterali spioventi dei due anzidetti profili trapezoidali. In order to ensure even greater fixing stability to the bracket according to the invention, it is envisaged that it may have additional through holes (always intended for the passage of respective screws) also in correspondence with the sloping side edges of the two aforementioned trapezoidal profiles.
Naturalmente la staffa medesima reca altresì, al centro della sua anzidetta struttura concava a croce, un grosso foro passante attraverso il quale può aggettare verso l’alto lo stelo filettato di un bullone infilato al suo interno fino a battuta, dal basso verso l’alto. Of course, the bracket itself also bears, in the center of its aforementioned concave cross-shaped structure, a large through hole through which the threaded stem of a bolt inserted into it up to the stop can project upwards, from the bottom upwards. .
Per maggiore chiarezza esplicativa la descrizione del trovato prosegue con riferimento alle tavole di disegno allegate, aventi solo valore illustrativo e non certo limitativo, in cui: For greater explanatory clarity, the description of the invention continues with reference to the attached drawing tables, having only illustrative and certainly not limiting value, in which:
- la figura 1 mostra, con una rappresentazione assonometrica, le modalità di montaggio della staffa in questione su una copertura per tetti realizzata con solai dotati di una superficie superiore liscia; - figure 1 shows, with an axonometric representation, the ways of mounting the bracket in question on a roof covering made with floors with a smooth upper surface;
- le figure 2 e 3 mostrano, con analoghe rappresentazioni assonometriche, le modalità di montaggio della staffa medesima su due tipi alternativi di pannelli grecati, differenziati soltanto per la configurazione delle rispettive costole trapezoidali; Figures 2 and 3 show, with analogous axonometric representations, the mounting methods of the same bracket on two alternative types of corrugated panels, differentiated only by the configuration of the respective trapezoidal ribs;
- la figura 4 è analoga alle precedenti ma si riferisce ad una versione alternativa della staffa in questione; - figure 4 is similar to the previous ones but refers to an alternative version of the bracket in question;
- la figura 5 è una rappresentazione assonometrica che mostra da sola la staffa di figura 4. - figure 5 is an axonometric representation which alone shows the bracket of figure 4.
Con riferimento alle figure 1, 2 e 3, la staffa in questione (1), che reca una forma in pianta sostanzialmente quadrata, adotta un corpo scatolare sostanzialmente a croce, formato grazie all’intersezione di due profili rettilinei cavi (2, 3), dotati di una sezione sostanzialmente trapezoidale. With reference to figures 1, 2 and 3, the bracket in question (1), which has a substantially square shape, adopts a substantially cross-shaped box-like body, formed thanks to the intersection of two hollow straight profiles (2, 3) , equipped with a substantially trapezoidal section.
In realtà il primo (2) di tali profili adotta fianchi laterali (2a) maggiormente divaricati rispetto ai corrispondenti fianchi laterali (3a) del secondo di tali profili (3). In reality, the first (2) of these profiles adopts side sides (2a) which are more widely spaced than the corresponding side sides (3a) of the second of these profiles (3).
In corrispondenza della parete orizzontale superiore di entrambi detti profili (2, 3) sono previsti rispettivi fori circolari passanti (2b, 3b), mentre nel punto di intersezione degli stessi è previsto un ulteriore foro circolare passante (4), di maggiore sezione. Corresponding to the upper horizontal wall of both said profiles (2, 3) respective circular through holes (2b, 3b) are provided, while at the point of intersection of the same there is a further circular through hole (4), of greater section.
Inutile dire che quest’ultimo è quello destinato ad essere attraversato, dal basso verso l’alto, da un rispettivo stelo filettato (10), ad asse sostanzialmente verticale, effettivamente destinato ad essere sfruttato per il fissaggio della struttura portante di sovrastanti pannelli fotovoltaici. It goes without saying that the latter is the one intended to be crossed, from bottom to top, by a respective threaded stem (10), with a substantially vertical axis, actually intended to be used for fixing the supporting structure of overlying photovoltaic panels.
Alla base dell’anzidetto corpo scatolare a croce, ed in posizione intermedia ai quattro rami dello stesso, sono previsti quattro piastrini “angolari” (5), sostanzialmente quadrati, ciascuno dei quali dotato centralmente di un foro passante (5a). At the base of the aforementioned cross-shaped box-like body, and in an intermediate position to the four branches of the same, there are four substantially square "angular" plates (5), each of which centrally equipped with a through hole (5a).
La figura 1 mostra, in particolare, le modalità di fissaggio della staffa in questione (1) al di sopra di un solaio (S) dotato superiormente di una superficie perfettamente liscia. Figure 1 shows, in particular, the ways of fixing the bracket in question (1) above a floor (S) with a perfectly smooth surface at the top.
In questo contesto, come anticipato, la staffa medesima (1) va appoggiata al solaio (S) in corrispondenza dei suoi anzidetti piastrini angolari (5) – che finiscono dunque per fungere quali veri e propri piedini di appoggio – prima di essere stabilmente fissata grazie all’impiego di viti infilate dall’alto verso il basso attraverso i fori passanti (5a) dei piastrini medesimi (5), sì da potersi impegnarsi nel solaio medesimo (S). In this context, as anticipated, the bracket itself (1) must be placed on the floor (S) in correspondence with its aforementioned corner plates (5) - which therefore end up acting as real support feet - before being stably fixed thanks to the use of screws inserted from top to bottom through the through holes (5a) of the plates themselves (5), so as to be able to engage in the floor itself (S).
Le figure 2 e 3 mostrano invece la staffa in parola (1) in combinazione con due pannelli grecati (P1, P2) che differiscono tra loro per la sezione adottata in corrispondenza delle rispettive costole (C1, C2). Figures 2 and 3 instead show the bracket in question (1) in combination with two corrugated panels (P1, P2) which differ from each other in the section adopted at the respective ribs (C1, C2).
Il medesimo esemplare della staffa in questione (1) può essere montata esattamente a cavallo dell’una o dell’altra di dette costole (C1, C2) – con la necessaria interposizione di una guarnizione in polietilene (6) – selezionandone di volta in volta il profilo rettilineo (2, 3) effettivamente corrispondente. The same example of the bracket in question (1) can be mounted exactly astride one or the other of said ribs (C1, C2) - with the necessary interposition of a polyethylene gasket (6) - selecting each time the rectilinear profile (2, 3) actually corresponding.
Una volta eseguita una simile posa in opera, si ribadisce che l’accoppiamento può essere stabilizzato utilizzando viti ad asse verticale infilate dall’alto verso il basso entro gli anzidetti fori passanti (2b, 3b) dei profili medesimi (2, 3), sì da penetrare anch’esse nella struttura poliuretanica delle costole (C1, C2) del rispettivo pannello (P1, P2). Once a similar installation has been carried out, it is reiterated that the coupling can be stabilized using vertical axis screws inserted from top to bottom within the aforementioned through holes (2b, 3b) of the profiles themselves (2, 3), yes also to penetrate into the polyurethane structure of the ribs (C1, C2) of the respective panel (P1, P2).
Si richiama peraltro l’attenzione sul fatto che l’anzidetta guarnizione (6), utilizzata in presenza di pannelli grecati, assolve ad una duplice vantaggiosa funzione. Attention is also drawn to the fact that the aforementioned gasket (6), used in the presence of corrugated panels, performs a double advantageous function.
Da un lato essa serve ad impedire qualsiasi infiltrazione d’acqua, in direzione della struttura poliuretanica interna di un pannello (P1, P2), attraverso i fori eseguiti in corrispondenza delle rispettive costole (C1, C2) in occasione della posa in opera delle viti di fissaggio della staffa (1). On the one hand, it serves to prevent any infiltration of water, in the direction of the internal polyurethane structure of a panel (P1, P2), through the holes made in correspondence with the respective ribs (C1, C2) when installing the screws. fixing bracket (1).
Dall’altro lato la medesima guarnizione (6) vanta la capacità – grazie all’intrinseca elasticità della propria struttura in polietilene – di favorire l’ottimale accoppiamento dei due profili trapezoidali (2, 3) della staffa medesima (1) anche su costole di pannelli grecati dotate di una sezione non perfettamente compatibile. On the other hand, the same gasket (6) boasts the ability - thanks to the intrinsic elasticity of its polyethylene structure - to favor the optimal coupling of the two trapezoidal profiles (2, 3) of the same bracket (1) even on the ribs of corrugated panels with a section that is not perfectly compatible.
È certamente vero che la specifica forma attribuita ai medesimi profili trapezoidali (2, 3) è stata realizzata in funzione delle due più diffuse tipologie di grecature dei pannelli da copertura per tetti. It is certainly true that the specific shape attributed to the same trapezoidal profiles (2, 3) was made according to the two most common types of corrugated roof panels.
Ciò non toglie però che esistano in commercio anche altre versioni di tali pannelli grecati, tra loro differenziate proprio in ragione della specifica configurazione della sezione trapezoidale delle rispettive costole. However, this does not mean that other versions of these corrugated panels also exist on the market, differentiated from each other precisely by virtue of the specific configuration of the trapezoidal section of the respective ribs.
In tali casi, dunque, la forma di tali costole risulterebbe non perfettamente adattabile a quella dei profili trapezoidali (2, 3) della staffa secondo il trovato (1). In such cases, therefore, the shape of these ribs would not be perfectly adaptable to that of the trapezoidal profiles (2, 3) of the bracket according to the invention (1).
Ebbene, in un simile contesto, l’interposizione dell’anzidetta guarnizione (6) si rivela particolarmente utile ai fini della compensazione delle anzidette differenze morfologiche rivelabili tra la sezione di una costola di un pannello grecato e la sezione di uno dei profili trapezoidali (2, 3) della staffa medesima (1) e dunque ai fini dell’eliminazione di qualsiasi possibile “gioco” tra l’una e l’altro. Well, in a similar context, the interposition of the aforementioned gasket (6) is particularly useful for the purposes of compensating for the aforementioned morphological differences that can be detected between the section of a rib of a corrugated panel and the section of one of the trapezoidal profiles (2 , 3) of the bracket itself (1) and therefore for the purpose of eliminating any possible "play" between one and the other.
Al momento della posa in opera delle viti di fissaggio, infatti, la stessa guarnizione (6) è destinata comunque a restare strettamente schiacciata tra la costola (C1, C2) del pannello grecato ed il profilo trapezoidale (2, 3) della staffa (1), essendo tuttavia evidente che tale schiacciamento assumerà valori maggiori o minori proprio in funzione della specifica differenza morfologica rilevabile tra la sezione della costola e quella del rispettivo profilo trapezoidale. In fact, when the fixing screws are installed, the same gasket (6) is in any case destined to remain tightly compressed between the rib (C1, C2) of the corrugated panel and the trapezoidal profile (2, 3) of the bracket (1 ), it being however evident that this flattening will assume greater or lesser values precisely in function of the specific morphological difference detectable between the section of the rib and that of the respective trapezoidal profile.
Le figure 4 e 5 mostrano una versione alternativa della staffa secondo il trovato (11), destinata preferibilmente ad essere realizzata per stampaggio di materiali plastici. Figures 4 and 5 show an alternative version of the bracket according to the invention (11), preferably intended to be made by molding plastic materials.
La sua prima peculiarità consiste nel fatto che le pareti superiori dei rispettivi profili trapezoidali (2, 3) sono delimitate, su entrambi lati, da rispettive spondine rialzate (2c, 3c). Its first peculiarity consists in the fact that the upper walls of the respective trapezoidal profiles (2, 3) are delimited, on both sides, by respective raised sides (2c, 3c).
Ulteriore peculiarità di questa versione della staffa in questione (11) risiede nel fatto di adottare fori passanti (2d, 3d), destinati all’inserimento di rispettive viti di fissaggio, anche in corrispondenza dei fianchi laterali spioventi (2a, 3a) dei due profili trapezoidali (2, 3). A further peculiarity of this version of the bracket in question (11) lies in the fact of adopting through holes (2d, 3d), intended for the insertion of respective fixing screws, also in correspondence with the sloping lateral sides (2a, 3a) of the two profiles trapezoidal (2, 3).
A ciò si aggiunga la presenza, nel punto di incrocio dei due medesimi profili trapezoidali (2, 3), di un’appendice cava aggettante verso l’alto, costituita da un tratto inferiore (7) sagomato ad imitazione della testa poligonale di un bullone e da un tratto superiore sostanzialmente cilindrico (8), l’uno e l’altro attraversati da un foro ad asse verticale (9). To this is added the presence, at the point of intersection of the two same trapezoidal profiles (2, 3), of a hollow appendage projecting upwards, consisting of a lower section (7) shaped in imitation of the polygonal head of a bolt and by a substantially cylindrical upper portion (8), both of which are crossed by a hole with a vertical axis (9).
Questo foro (9) è destinato ad essere attraversato, dal basso verso l’alto, dallo stelo filettato (10) di un bullone, la cui testa è invece destinata ad insediarsi esattamente – senza possibilità di libera rotazione – entro il tratto inferiore poligonale (7) dell’apposita anzidetta appendice. This hole (9) is intended to be crossed, from the bottom upwards, by the threaded stem (10) of a bolt, whose head is instead destined to settle exactly - without the possibility of free rotation - within the lower polygonal section ( 7) of the aforementioned appendix.
In tal modo la testa del bullone medesimo non crea ingombri in corrispondenza della faccia inferiore della staffa in questione (11), mentre il rispettivo stelo filettato (10) può aggettare verso l’alto ed essere vantaggiosamente sfruttato per il fissaggio di due pannelli fotovoltaici adiacenti (F). In this way the head of the bolt itself does not create bulk in correspondence with the lower face of the bracket in question (11), while the respective threaded stem (10) can project upwards and be advantageously used for fixing two adjacent photovoltaic panels. (F).
A tale riguardo si rimanda espressamente alla figura 4 che mostra come un simile stelo filettato (10) sia destinato a restare interposto tra i bordi ravvicinati di due pannelli fotovoltaici (F) appoggiati da parti opposte su un medesimo esemplare della staffa in questione (11), proprio al di sopra delle sue anzidette spondine rialzate (2c, 3c). In this regard, please refer expressly to figure 4 which shows how a similar threaded stem (10) is destined to remain interposed between the close edges of two photovoltaic panels (F) resting on opposite sides on the same example of the bracket in question (11) , just above its aforementioned raised sides (2c, 3c).
In questo contesto occorre infilare lungo lo stelo medesimo (10), dall’alto verso il basso, un piastrino stampato (12) che, dopo essersi posizionato al di sopra degli anzidetti bordi ravvicinati dei due pannelli fotovoltaici adiacenti (F), può essere fissato stabilmente in tale assetto per il tramite di un opportuno dado di serraggio (13). In this context it is necessary to insert along the same stem (10), from top to bottom, a molded plate (12) which, after being positioned above the aforementioned close edges of the two adjacent photovoltaic panels (F), can be fixed stably in this setting by means of a suitable tightening nut (13).
Va detto peraltro che quest’ultima versione della staffa in questione (11) è destinata preferibilmente ad essere realizzata per stampaggio di materiali plastici, al pari dell’anzidetto piastrino (12) destinato al fissaggio degli anzidetti pannelli fotovoltaici (F) che risultano invece dotati di una struttura metallica. It should also be said that this last version of the bracket in question (11) is preferably intended to be made by molding plastic materials, like the aforementioned plate (12) intended for fixing the aforementioned photovoltaic panels (F) which are instead equipped of a metal structure.
Nel momento, infatti, in cui questi ultimi pannelli (F) poggiano sulle anzidette spondine rialzate (2c, 3c) della staffa in questione (11), risulta evidente come gli stessi siano impossibilitati a portarsi a diretto contatto contro la testa metallica delle viti di fissaggio infilate dall’alto in basso nei fori (2b, 3b) previsti superiormente ai profili trapezoidali (2, 3). In fact, when these latter panels (F) rest on the aforementioned raised sides (2c, 3c) of the bracket in question (11), it is evident that they are unable to come into direct contact with the metal head of the screws. fixing threaded from top to bottom in the holes (2b, 3b) provided at the top of the trapezoidal profiles (2, 3).
È come dire che la presenza delle anzidette spondine rialzate (2c, 3c) consente di ottenere un isolamento elettrico tra i pannelli fotovoltaici (F) e le anzidette viti di fissaggio, utile ad impedire il manifestarsi di correnti vaganti, laddove la staffa (11) venisse stampata in materiale non conduttivo, come ad esempio in plastica. It is like saying that the presence of the aforementioned raised sides (2c, 3c) allows to obtain an electrical insulation between the photovoltaic panels (F) and the aforementioned fixing screws, useful to prevent the occurrence of stray currents, where the bracket (11) was printed in non-conductive material, such as plastic.
