DESCRIZIONE DESCRIPTION
“DISPOSITIVO DI COLLEGAMENTO DI UN PANNELLO SOLARE AD UNA LASTRA GRECATA†⠀ œDevice for connecting a solar panel to a corrugated plateâ €
La presente invenzione à ̈ relativa ad un dispositivo di collegamento di un pannello solare ad una lastra grecata. The present invention relates to a device for connecting a solar panel to a corrugated sheet.
Nel campo dell’installazione di pannelli solari su coperture comprendenti lastre grecate o nervate, ad esempio realizzate in lamiera, à ̈ noto di utilizzare staffe di attacco universali, ossia accoppiabili praticamente ad ogni tipologia di lastra, di posizionare le staffe lungo una nervatura della lastra in funzione delle dimensioni dei pannelli solari da accoppiare, di fissare le staffe alla sottostante struttura di supporto delle lastre grecate mediante viti attraversanti ortogonalmente le lastre grecate stesse e di sovrapporre il pannello solare alle staffe per poi collegarlo alle staffe stesse mediante viti. In the field of installing solar panels on roofs comprising corrugated or ribbed sheets, for example made of sheet metal, it is known to use universal attachment brackets, that is to say that can be coupled to practically any type of sheet, to position the brackets along a rib of the plate according to the size of the solar panels to be coupled, to fix the brackets to the underlying support structure of the corrugated sheets by means of screws crossing orthogonally the corrugated sheets themselves and to superimpose the solar panel on the brackets and then connect it to the brackets themselves by means of screws.
La modalità di collegamento nota, sebbene utilizzata risulta essere scarsamente soddisfacente, innanzitutto, per il fatto che richiede il collegamento alla sottostante struttura di supporto della lastre grecate. Questo fatto, qualora, la sottostante struttura di supporto sia del tipo a traverse, rende spesso difficoltoso individuare ed intercettare la traversa corrispondente alla posizione della staffa e comunque espone il montatore alla possibilità che in corrispondenza della stessa staffa non sia presente una traversa. Questo problema à ̈ particolarmente sentito in strutture di supporto esistenti. The known connection method, although used, is not very satisfactory, first of all, due to the fact that it requires connection to the underlying support structure of the corrugated sheets. This fact, if the underlying support structure is of the crosspiece type, often makes it difficult to identify and intercept the crosspiece corresponding to the position of the bracket and in any case exposes the assembler to the possibility that there is no crosspiece in correspondence with the same bracket. This problem is particularly felt in existing support structures.
Inoltre, tra la staffa e la nervatura sono normalmente presenti dei giochi, a volte per comodità di attacco anche rilevanti, che permettono alla staffa, in determinate condizioni di carico, di muoversi rispetto alla nervatura o di deformarsi plasticamente compromettendo, in entrambi i casi, il collegamento, la stabilità e l’integrità delle lastre. Furthermore, between the bracket and the rib there are normally some play, sometimes for ease of attachment, even significant, which allow the bracket, under certain load conditions, to move with respect to the rib or to deform plastically, compromising, in both cases, the connection, stability and integrity of the sheets.
Scopo della presente invenzione à ̈ quello di realizzare un dispositivo di collegamento di un pannello solare ad una lastra grecata, il quale permetta di risolvere in maniera estremamente semplice ed economica i problemi connessi alle soluzioni note. The object of the present invention is to provide a device for connecting a solar panel to a corrugated plate, which allows the problems connected to known solutions to be solved in an extremely simple and economical way.
Secondo la presente invenzione viene realizzato un dispositivo per il collegamento di un pannello solare ad una lastra grecata comprendente una nervatura allungata; il dispositivo comprendendo un corpo allungato cavo di attacco atto ad accoppiarsi positivamente alla detta nervatura, mezzi di collegamento per collegare il detto corpo allungato unicamente alla detta nervatura, una staffa di ritenzione atta ad accoppiarsi al detto pannello, ed un assieme di collegamento a guida e slitta interposto tra la detta staffa di ritenzione ed il detto corpo allungato. According to the present invention, a device is provided for connecting a solar panel to a corrugated plate comprising an elongated rib; the device comprising an elongated hollow attachment body adapted to positively couple to said rib, connecting means for connecting said elongated body solely to said rib, a retention bracket capable of coupling to said panel, and a guide and connecting assembly slide interposed between said retention bracket and said elongated body.
Preferibilmente, nel dispositivo sopra definito il corpo allungato delimita un canale allungato presentante una forma complementare alla detta nervatura. Preferably, in the device defined above, the elongated body defines an elongated channel having a shape complementary to said rib.
L'invenzione verrà ora descritta con riferimento ai disegni annessi, che ne illustrano un esempio di attuazione non limitativo, in cui: The invention will now be described with reference to the attached drawings, which illustrate a non-limiting example of embodiment, in which:
la figura 1 illustra in vista prospettica una preferita forma di attuazione del dispositivo di collegamento interposto tra un pannello solare ed una lastra grecata; Figure 1 is a perspective view of a preferred embodiment of the connection device interposed between a solar panel and a corrugated plate;
la figura 2 Ã ̈ una sezione in scala fortemente ingrandita secondo la linea II-II della figura 1; e Figure 2 is a section on a greatly enlarged scale along the line II-II of Figure 1; And
la figura 3 Ã ̈ una vista prospettiva schematica esplosa del dispositivo della figura 2. Figure 3 is an exploded schematic perspective view of the device of Figure 2.
Nella figura 1, con 1 à ̈ indicata, nel suo complesso, una copertura comprendente una pluralità di lastre 2 di lamiera grecata, ciascuna delle quali comprende, a sua volta, una o più nervature 3 longitudinali. Nel particolare esempio descritto, le nervature 3 presentano in sezione trasversale una forma trapezoidale, come visibile nella figura 2. In Figure 1, 1 denotes, as a whole, a cover comprising a plurality of sheets 2 of corrugated sheet metal, each of which in turn comprises one or more longitudinal ribs 3. In the particular example described, the ribs 3 have a trapezoidal shape in cross section, as can be seen in Figure 2.
Le lastre 2 supportano due o più pannelli solari 4, di per se noti e non descritti in dettaglio, ciascuno dei quali à ̈ collegato alle nervature 3 tramite dispositivo di collegamento regolabili e rilasciabili, indicati con 6. The plates 2 support two or more solar panels 4, known per se and not described in detail, each of which is connected to the ribs 3 by means of an adjustable and releasable connection device, indicated with 6.
Ciascun dispositivo 6 collega il relativo pannello 4 direttamente ed unicamente alla corrispondente nervatura 3 senza interessare una sottostante struttura di supporto delle lastre 2 e comprende un corpo allungato 7 cavo, il quale alloggia un corrispondente tratto della relativa nervatura 3 e delimita un canale 7a avente una sezione traversale complementare a quella della nervatura 3 stessa. Convenientemente, il corpo allungato 7 à ̈ costituito da uno spezzone monolitico estruso in lega di alluminio e comprende una parete centrale 8 piana e due pareti laterali 10 inclinate disposte, ciascuna, parallelamente ad una rispettiva parete laterale 10a della nervatura 3 e convergenti l’una verso l’altra e verso la parete centrale 8 e due porzioni 11 di appoggio sulla lastra 3 estendentisi dalle rispettive pareti laterali parallelamente alla parete centrale 8. Each device 6 connects the relative panel 4 directly and only to the corresponding rib 3 without involving an underlying support structure of the plates 2 and comprises an elongated hollow body 7, which houses a corresponding portion of the relative rib 3 and defines a channel 7a having a cross section complementary to that of the rib 3 itself. Conveniently, the elongated body 7 is made up of a monolithic extruded piece in aluminum alloy and comprises a flat central wall 8 and two inclined side walls 10 each arranged parallel to a respective side wall 10a of the rib 3 and converging the one towards the other and towards the central wall 8 and two supporting portions 11 on the plate 3 extending from the respective side walls parallel to the central wall 8.
Le superfici interne delle pareti 8,10 e 11 sono rivestite con uno strato 12 di materiale elastomerico, convenientemente un monomero comprendente etilene e/o propilene portato dal corpo allungato 7. Il corpo allungato 7 à ̈ bloccato sulla relativa nervatura 3 con lo strato 12 forzato tra la nervatura 3 ed il corpo allungato 7 stesso tramite due o più viti 13 di bloccaggio inserite unicamente tra le pareti 10 e 10a (figura 2). The internal surfaces of the walls 8, 10 and 11 are coated with a layer 12 of elastomeric material, conveniently a monomer comprising ethylene and / or propylene carried by the elongated body 7. The elongated body 7 is blocked on the relative rib 3 with the layer 12 forced between the rib 3 and the elongated body 7 itself by means of two or more locking screws 13 inserted only between the walls 10 and 10a (figure 2).
Con riferimento alla figura 2, il dispositivo 6 comprende, inoltre, un’assieme 14 regolabile di attacco del pannello 4 al corpo allungato 7. L’assieme 14 à ̈ del tipo a guida e slitta e comprende una guida rettilinea 15 a C rovesciato, la quale à ̈ integrale al corpo allungato 7 ed à ̈ definita dalla parete 8 di fondo e da due pareti laterali 16 ad T estendentisi verso il pannello 4 dalla stessa parete centrale 8. I pannelli 3 sono direttamente appoggiati sulle ali 17 delle pareti laterali 16 a T. With reference to Figure 2, the device 6 also comprises an adjustable assembly 14 for attachment of the panel 4 to the elongated body 7. The assembly 14 is of the guide and slide type and comprises a straight guide 15 in C overturned, which is integral with the elongated body 7 and is defined by the back wall 8 and by two T-shaped side walls 16 extending towards the panel 4 from the same central wall 8. The panels 3 rest directly on the wings 17 of the walls side 16 to T.
L’assieme 14 comprende poi una slitta 18 accoppiata alla guida 15 in maniera scorrevole ed in posizione trasversalmente fissa e portante una madrevite 19. La slitta 18 comprende poi una vite 20 di serraggio accoppiata alla madrevite 19 e sporgente all’esterno della guida attraverso una staffa 22 di ritenzione, che costituisce anch’essa parte della slitta 18. Convenientemente, la staffa 22 comprende uno spallamento 23 per una testa 24 della vite 20 ed una porzione 25 di ritenzione disposta in battuta o in appoggio contro un bordo perimetrale 26 del pannello 4 per spingere, a seguito del serraggio della vite 20 il pannello 4 contro la guida 15. The assembly 14 then comprises a slide 18 coupled to the guide 15 in a sliding manner and in a transversely fixed position and carrying a nut screw 19. The slide 18 then comprises a tightening screw 20 coupled to the nut screw 19 and protruding outside the guide through a retention bracket 22, which also forms part of the slide 18. Conveniently, the bracket 22 comprises a shoulder 23 for a head 24 of the screw 20 and a retention portion 25 arranged abutting or resting against a perimeter edge 26 of the panel 4 to push, following the tightening of the screw 20, the panel 4 against the guide 15.
In uso, stabilita la posizione di ciascun pannello 4, i relativi corpi allungati 7 vengono posizionati ed accoppiati alle nervature 3 e in modo da disporsi a cavallo delle stesse nervature 3 e parzialmente al di sotto dei rispettivi pannelli 4. A questo punto, ciascun corpo allungato 7 viene collegato stabilmente alla relativa nervatura 3 tramite le viti 13, dopo di che la relativa slitta 18 viene traslata verso il pannello 4 fino a portare la staffa 22 in accoppiamento al bordo perimetrale 26 del pannello. La vite 20 viene, quindi, serrata ed il pannello 4 bloccato contro le ali 17 delle porzioni laterali 16. In use, once the position of each panel 4 has been established, the relative elongated bodies 7 are positioned and coupled to the ribs 3 and so as to be arranged astride the same ribs 3 and partially below the respective panels 4. At this point, each body elongated 7 is stably connected to the relative rib 3 by means of the screws 13, after which the relative slide 18 is translated towards the panel 4 until the bracket 22 is coupled to the perimeter edge 26 of the panel. The screw 20 is then tightened and the panel 4 locked against the wings 17 of the side portions 16.
Da quanto precede appare evidente come il dispositivo 6 descritto possa innanzitutto essere stabilmente collegate unicamente alle lastre 2 semplicemente utilizzando viti inserite attraverso le corrispondenti nervature 3 senza interessare in alcun modo la sottostante struttura di supporto delle lastre 2 che può, pertanto, presentare qualsiasi configurazione o geometria ed essere realizzata di qualsiasi materiale. From the foregoing it is evident that the device 6 described can first of all be stably connected only to the plates 2 simply by using screws inserted through the corresponding ribs 3 without affecting in any way the underlying support structure of the plates 2 which can therefore have any configuration or geometry and be made of any material.
Inoltre, il corpo allungato 7 si accoppia perfettamente alla relativa nervatura senza sostanziali possibilità di movimento sotto carico, e tale accoppiamento à ̈ reso ancora più stabile dalla presenza dello strato 12 che, peraltro, preserva la lastra da rigature e/o eventuali accidentali incisioni. Furthermore, the elongated body 7 is perfectly coupled to the relative rib without substantial possibility of movement under load, and this coupling is made even more stable by the presence of the layer 12 which, moreover, protects the sheet from scratches and / or any accidental incisions.
Infine, il dispositivo 6 descritto permette una agevole regolazione della staffa 22 ed un ancora più agevole ed immediato bloccaggio del pannello 4. Finally, the device 6 described allows easy adjustment of the bracket 22 and an even easier and more immediate locking of the panel 4.
Da quanto precede appare infine evidente, che al dispositivo 6 descritto possono essere apportate modifiche e varianti. In Particolare, diverse da quelle descritte potrebbero essere la geometria e le dimensioni del corpo 7 di attacco per adattarsi a nervature diverse da quelle descritte a titolo di esempio. Finally, it is evident from the foregoing that modifications and variations can be made to the device 6 described. In particular, the geometry and dimensions of the attachment body 7 could be different from those described in order to adapt to ribs different from those described by way of example.
Inoltre, il corpo allungato 7 descritto potrebbe presentare una lunghezza maggiore di una dimensione longitudinale del relativo pannello 4 e portare almeno due dei citati assiemi 14 a guida e slitta. Furthermore, the elongated body 7 described could have a length greater than a longitudinal dimension of the relative panel 4 and carry at least two of the aforementioned guide and slide assemblies 14.
Inoltre, anche l’assieme 14 a guida e slitta potrebbe essere diverso da quello descritto a titolo di esempio, così come diversa da quella indicata potrebbe essere la staffa 22 per accoppiarsi e trattenere specifiche porzioni di attacco del pannello solare. Furthermore, the guide and slide assembly 14 could also be different from that described by way of example, as well as the bracket 22 for coupling and retaining specific attachment portions of the solar panel could be different from that indicated.
