DESCRIZIONE DESCRIPTION
a corredo di una domanda di brevetto per invenzione industriale avente per titolo: accompanying a patent application for an industrial invention entitled:
“MODULO AUTOPORTANTE, INTEGRATO CON PANNELLI FOTOVOLTAICI, PER LA COPERTURA DI EDIFICI”. "SELF-SUPPORTING MODULE, INTEGRATED WITH PHOTOVOLTAIC PANELS, FOR COVERING BUILDINGS".
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente invenzione ha per oggetto una struttura modulare, autoportante, per la copertura di edifici, in particolare per coperture a shed, la quale presenta una configurazione a guscio e incorpora uno strato di pannelli fotovoltaici , che si integrano con detta struttura contribuendo ad incrementarne le caratteristiche di resistenza meccanica , di coibentazione e di impermeabilità del modulo . The present invention relates to a modular, self-supporting structure for roofing buildings, in particular for shed roofs, which has a shell configuration and incorporates a layer of photovoltaic panels, which integrate with said structure, helping to increase its mechanical resistance, insulation and waterproofing characteristics of the module.
Per meglio comprendere l’originalità della struttura di copertura secondo il trovato si ritiene opportuno accennare come attualmente viene realizzata una struttura di copertura a shed . To better understand the originality of the roofing structure according to the invention, it is considered appropriate to mention how a shed roofing structure is currently made.
La soluzione tradizionale prevede l’assemblaggio in opera di un struttura composta dai seguenti elementi: The traditional solution involves the assembly on site of a structure consisting of the following elements:
- una struttura portante in acciaio che costituisce l’orditura secondaria e che viene ancorata alla travi di copertura principali delle edificio, generalmente in conglomerato cementizio armato vibrato o compresso oppure anch’esse in acciaio ; - a steel supporting structure that constitutes the secondary framework and which is anchored to the main roof beams of the building, generally in vibrated or compressed reinforced concrete or steel;
- una serie di arcarecci in acciaio, che vengono fissati sopra la anzidetta struttura portante con il compito di ripartire i carichi sulla orditura secondaria : - a series of steel purlins, which are fixed above the aforementioned bearing structure with the task of distributing the loads on the secondary frame:
- un manto di copertura termoisolante, realizzato con pannelli sandwich, in doppia lamiera di acciaio, con interposto uno strato coibente in poliuretano espanso o lana minerale, i quali vengono fissati sopra detti arcarecci con il compito principale di assolvere ad una funzione di impermeabilizzazione e di coibentazione . - a thermal insulating roof covering, made with sandwich panels, in double steel sheet, with an insulating layer of polyurethane foam or mineral wool interposed, which are fixed above said purlins with the main task of performing a waterproofing and insulation.
La combinazione di questi tre elementi costituisce di per sé una struttura di copertura “finita” nel senso di essere in grado di assolvere a funzioni strutturali, di isolamento termico e di impermeabilizzazione . The combination of these three elements constitutes in itself a “finished” roof structure in the sense of being able to perform structural, thermal insulation and waterproofing functions.
Nel caso in cui venga richiesto Γ installazione a tetto di un impianto fotovoltaico , detta struttura “finita” viene oggi comunemente integrata con i seguenti elementi : In the event that a rooftop installation of a photovoltaic system is required, said "finished" structure is now commonly integrated with the following elements:
- una intelaiatura realizzata con profilati di acciaio, ancorata al di sopra degli anzidetti pannelli “sandwich”, con il compito di fungere da struttura di sostegno sopraelevato e di fissaggio dei pannelli fotovoltaici ; - a framework made with steel profiles, anchored above the aforementioned "sandwich" panels, with the task of acting as an elevated support structure and fixing the photovoltaic panels;
- una serie di pannelli fotovoltaici che vengono adagiati ed fissati detta intelaiatura . - a series of photovoltaic panels that are placed and fixed to said frame.
Da questa semplice descrizione si evince innanzitutto come attualmente i pannelli fotovoltaici non si integrano con la sottostante struttura di copertura “finita” al fine di accrescerne le proprietà meccaniche, termoisolanti e impermeabilizzanti. Fra l’altro si è altresì notato che detti pannelli sandwich, pur incorporando una doppia lamiera di acciaio, non sono in grado di offrire alcun contributo strutturale alla sottostante struttura portante in acciaio che costituisce l’orditura secondaria e che viene ancorata alla travi di copertura principali delle edificio. Detta incapacità è dovuta al fatto che dette lamiere - che potrebbero dare un’apprezzabile contributo se sollecitate a trazione - si trovano all’estradosso di un elemento inflesso e dunque in una zona in cui sussistono soltanto sollecitazioni di compressione. From this simple description it is clear first of all that photovoltaic panels currently do not integrate with the underlying "finished" roofing structure in order to increase their mechanical, heat-insulating and waterproofing properties. Among other things, it has also been noted that said sandwich panels, while incorporating a double steel sheet, are not able to offer any structural contribution to the underlying steel supporting structure which constitutes the secondary framework and which is anchored to the roof beams. main of the building. This inability is due to the fact that said sheets - which could make an appreciable contribution if stressed by traction - are located on the extrados of an inflected element and therefore in an area where there are only compressive stresses.
Scopo della presente invenzione è quello di realizzare una struttura modulare autoportante, integrata con pannelli fotovoltaici e pannelli termoisolanti, la quale si presti ad essere prefabbricata per poi essere trasportata e posta in opera sul cantiere di costruzione del edificio . The purpose of the present invention is to provide a self-supporting modular structure, integrated with photovoltaic panels and thermal insulating panels, which can be prefabricated and then transported and installed on the construction site of the building.
Ulteriore scopo della presente invenzione è quello di realizzare una struttura modulare autoportante, del tipo appena sopra indicato, in cui tutti i componenti forniscono il loro contributo alla portanza complessiva della struttura, per cui risulta ottimizzato l’impiego dei materiali costruttivi di ciascun componente . A further purpose of the present invention is to create a self-supporting modular structure, of the type just indicated above, in which all the components provide their contribution to the overall bearing capacity of the structure, so that the use of the construction materials of each component is optimized.
In altre parole si potrebbe vedere la struttura modulare secondo il trovato come un’integrazione architettonica del fotovoltaico , in cui la superficie fotovoltaica stessa, oltre a garantire la produzione di energia elettrica, assolve alle seguenti funzioni tipiche di un involucro edilizio : In other words, the modular structure according to the invention could be seen as an architectural integration of the photovoltaic, in which the photovoltaic surface itself, in addition to guaranteeing the production of electricity, performs the following typical functions of a building envelope:
- la tenuta all’acqua e la conseguente impermeabilizzazione della struttura edilizia; - water tightness and consequent waterproofing of the building structure;
- una resistenza meccanica comparabile con quella di un convenzionale elemento edilizio di copertura; - a mechanical strength comparable to that of a conventional building roof element;
- un isolamento termico tale da non compromettere le prestazioni dell 'involucro edilizio. - a thermal insulation that does not compromise the performance of the building envelope.
Questi ed altri obiettivi sono stati raggiunti dalla struttura modulare integrata secondo l’invenzione, le cui caratteristiche innovative, principali e secondarie, sono puntualizzate nelle rivendicazioni allegate . These and other objectives have been achieved by the integrated modular structure according to the invention, whose innovative, main and secondary characteristics are detailed in the attached claims.
La struttura modulare integrata secondo il trovato consiste in una coppella prefabbricata, conformata a guscio, la quale è in grado di sostituire completamente l’orditura secondaria di travi ed il manto di tamponamento in una copertura tradizionale di edifici industriali. The integrated modular structure according to the invention consists of a prefabricated cupella, shaped like a shell, which is able to completely replace the secondary framework of beams and the infill covering in a traditional roofing of industrial buildings.
In seno a detta coppella, di sagoma rettangolare, si possono distinguere i seguenti componenti principali: Within this rectangular shaped cup, the following main components can be distinguished:
- una struttura portante realizzata con due o più profilati longitudinali, aventi interesse pari alla larghezza dei pannelli fotovoltaici di completamento impiegati, detti profilati longitudinali essendo collegati fra loro da traverse tubolari ; - a bearing structure made with two or more longitudinal profiles, having an interest equal to the width of the completion photovoltaic panels used, said longitudinal profiles being connected to each other by tubular crosspieces;
un pannello di coibentazione, del tipo a sandwich come quelli sopra descritti, che risulta fissato al di sotto di detta struttura portante e che va dunque a realizzare il soffitto a vista dell’ edificio; an insulation panel, of the sandwich type such as those described above, which is fixed below said load-bearing structure and which therefore creates the exposed ceiling of the building;
- una serie di pannelli fotovoltaici posti al di sopra di detta struttura portante; - a series of photovoltaic panels placed above said supporting structure;
- elementi di estradosso metallici per il sostegno , il fissaggio e la sigillatura della superficie fotovoltaica che chiude superiormente detta coppella a guscio . - metal extrados elements for supporting, fixing and sealing the photovoltaic surface that closes the upper shell.
Si sottolinea che nella coppella prefabbricata secondo il trovato la superficie fotovoltaica con i relativi sostegni non sia volta soltanto alla produzione di energia, ma costituisca parte integrante della coppella stessa, risultando necessaria per il suo corretto funzionamento in termini di tenuta all’acqua, resistenza meccanica e isolamento termico. It is emphasized that in the prefabricated cup according to the invention the photovoltaic surface with the relative supports is not aimed only at the production of energy, but constitutes an integral part of the cup itself, being necessary for its correct functioning in terms of water tightness, mechanical resistance. and thermal insulation.
Si noti inoltre che il pannello di coibentazione sia dislocato in corrispondenza dell’intradosso della coppella, e cioè dalla parte sollecitata a trazione, per cui le lamiere del pannello a sandwich possono fornire un apprezzabile contributo alla anzidetta struttura portante principale ( profilati longitudinali e traverse tubolari) per la definizione della portanza complessiva della coppella. It should also be noted that the insulation panel is located in correspondence with the intrados of the cupella, i.e. the part subjected to traction, so that the sheets of the sandwich panel can provide an appreciable contribution to the aforementioned main bearing structure (longitudinal profiles and tubular crosspieces ) for the definition of the overall bearing capacity of the cup.
Questa dislocazione del pannello di coibentazione in corrispondenza dell’intradosso della coppella secondo il trovato consente, in caso di incendio dell’edificio, di sfruttare il pannello medesimo anche quale schermo anti-fiamma di protezione della sovrastante struttura portante , senza dover sostenere, come attualmente avviene , i costi per rivestire il soffitto dell’edificio con speciali materiali ignifughi. This displacement of the insulation panel in correspondence with the intrados of the cupella according to the invention allows, in the event of a building fire, to exploit the panel itself also as an anti-flame protection screen for the overlying load-bearing structure, without having to support, as currently occurs, the costs of cladding the ceiling of the building with special fireproof materials.
La configurazione strutturale ed i vantaggi offerti da siffatta coppella balzeranno più chiari con la descrizione seguente che , per maggiore chiarezza esplicativa, prosegue con riferimento alle tavole di disegno allegate, aventi solo valore illustrativo e non certo limitativo, in cui: The structural configuration and the advantages offered by such a cup will jump clearer with the following description which, for greater clarity, continues with reference to the attached drawing tables, having only illustrative and certainly not limiting value, in which:

Con riferimento alle figure 1 , 2 e 3, la struttura modulare integrata secondo il trovato consiste in una coppella a guscio prefabbricata (1) , di sagoma rettangolare, in seno alla quale si possono distinguere i seguenti componenti principali: With reference to Figures 1, 2 and 3, the integrated modular structure according to the invention consists of a prefabricated shell cup (1), of rectangular shape, within which the following main components can be distinguished:
- una intelaiatura portante (A) , realizzata con una coppia parallela e distanziata di profilati in acciaio (10) orientati longitudinalmente e collegati fra loro da traverse tubolari (11). - a load-bearing frame (A), made with a parallel and spaced pair of longitudinally oriented steel sections (10) connected to each other by tubular crosspieces (11).
uno strato di coibentazione (B) fissato al di sotto della intelaiatura portante (A) e formato da un unico o da un serie complanare di pannelli di coibentazione (20), tipo a sandwich , ciascuno dei quali è realizzato in doppia lamiera di acciaio , con interposto uno strato di materiale termoisolante (21), - un mantello di copertura (C) realizzato con una serie complanare di pannelli fotovoltaici (PV), fissati al di sopra di detta intelaiatura portante (A). a layer of insulation (B) fixed below the load-bearing frame (A) and formed by a single or a coplanar series of sandwich-type insulation panels (20), each of which is made of double sheet steel, interposed with a layer of heat-insulating material (21), - a covering mantle (C) made with a coplanar series of photovoltaic panels (PV), fixed above said supporting frame (A).
Si precisa che nelle rappresentazioni grafiche allegate il foglio di lamiera superiore (20a) del pannello di coibentazione (20) reca un profilo grecato, mentre il foglio di lamiera inferiore (20b) reca un profilo rettilineo, ma possono essere impiegate anche due lamiere rettilinee, rimanendo immutata la funzione del pannello sandwich alfintemo del modulo in questione. It should be noted that in the attached graphical representations the upper sheet metal (20a) of the insulation panel (20) has a corrugated profile, while the lower sheet metal (20b) has a straight profile, but two straight sheets can also be used, the function of the sandwich panel at the end of the module in question remains unchanged.
Con particolare riferimento alla fig. 3, si precisa che ciascun profilato in acciaio (10) presenta una sezione scatolata avente profilo ad “Ω” squadrata, in seno alla quale è possibile distinguere: With particular reference to fig. 3, it should be noted that each steel section (10) has a boxed section with a squared "Ω" profile, within which it is possible to distinguish:
- una coppia distanziata di parete verticali (IOa), che recano alla base due piedi orizzontali (10b) sporgenti verso l’esterno ; - un’ala orizzontale di testa (10c) , che reca due tratti terminali (lOd) che sporgono al di fuori delle pareti verticali (IOa). - a spaced pair of vertical walls (10a), which have two horizontal feet (10b) protruding outwards at the base; - a horizontal head wing (10c), which has two terminal sections (10d) that protrude outside the vertical walls (10a).
Il collegamento del pannello di coibentazione (20) alla sovrastante intelaiatura portante (A) avviene con l’ausilio di un giunto metallico (G) che viene interposto fra il profilo in acciaio (10) e il pannello di coibentazione (20). The connection of the insulation panel (20) to the overlying load-bearing frame (A) takes place with the aid of a metal joint (G) which is interposed between the steel profile (10) and the insulation panel (20).
Più precisamente detto giunto (G) consiste in un cavallotto metallico (30) , avente sezione squadrata ad “U”. ed infilato fra le pareti verticali (IOa) del profilato (10), in modo tale che ali laterali (30a) del cavallotto (30) si attestino contro dette pareti verticali (IOa), mentre l’ala di base (30b) del cavallotto (30) va ad appoggiarsi sopra uno dei denti (22) del foglio di lamiera superiore (20a) dal profilo grecato, mentre detti piedi (10b) appoggiano su detto foglio di lamiera (20a), a cavallo dello stesso dente (22), come mostrato in fig. 3. More precisely, said joint (G) consists of a metal U-bolt (30), having a squared “U” section. and inserted between the vertical walls (10a) of the profile (10), so that the lateral wings (30a) of the U-bolt (30) abut against said vertical walls (10a), while the base wing (30b) of the U-bolt (30) rests on one of the teeth (22) of the upper sheet metal (20a) with the corrugated profile, while said feet (10b) rest on said sheet metal (20a), astride the same tooth (22), as shown in fig. 3.
L’ala di base (30b) del cavallotto (30) presenta uno o più fori centrali (31). The base wing (30b) of the U bolt (30) has one or more central holes (31).
Il fissaggio del cavallotto (30) al profilo di acciaio (10) avviene per mezzo di un bullone ad asse orizzontale (40) - con relativo dado (41) - il quale attraversa dette parerti verticali (10a) e dette ali verticali (30a), mentre il fissaggio del cavallotto (30) al sottostante pannello di coibentazione (20) avviene per mezzo di un viti autofilettanti (50) , ad asse verticale, che attraversano detto foro (31) e finterò pannello (20) , per impegnarsi in un profilato tubolare metallico (60) , che corre trasversalmente al di sotto del pannello (20). The fixing of the U-bolt (30) to the steel profile (10) takes place by means of a bolt with a horizontal axis (40) - with relative nut (41) - which passes through said vertical walls (10a) and said vertical wings (30a) , while the fixing of the U-bolt (30) to the underlying insulation panel (20) takes place by means of a self-tapping screws (50), with a vertical axis, which pass through said hole (31) and fake panel (20), to engage in a metal tubular section (60), which runs transversely under the panel (20).
Come già sottolineato, i profilati longitudinali (10) sono collegati fra loro da traverse tubolari (11) , che vengono associate, per mezzo di staffe sagomata a “Z” (70), a detti tratti terminali (lOd) . As already pointed out, the longitudinal profiles (10) are connected to each other by tubular crosspieces (11), which are associated, by means of "Z" shaped brackets (70), to said terminal sections (10d).
In effetti dette traverse tubolari (11) fungono da sostegno per i pannelli fotovoltaici (PV), il cui fissaggio ai sottostanti profilati longitudinali (10) avviene con l’ausilio ed l’interposizione di un listello scatolato (80) in alluminio , fissato longitudinalmente al di sopra dell’ala di testa (10c) per mezzo di comuni viti autofilettanti (81) . In fact, said tubular crosspieces (11) act as a support for the photovoltaic panels (PV), whose fixing to the underlying longitudinal profiles (10) takes place with the aid and interposition of a boxed strip (80) in aluminum, fixed longitudinally above the head wing (10c) by means of common self-tapping screws (81).
I bordi longitudinali delle coppie affiancate di pannello fotovoltaici (PV) vengono in effetti serrati fra detto listello (80) e un contro-listello listello in alluminio (82). The longitudinal edges of the side-by-side pairs of photovoltaic panels (PV) are effectively clamped between said strip (80) and an aluminum strip counter-strip (82).
La superficie fotovoltaica, costituita dai pannelli (PV), dalle relative connessioni in alluminio (80, 82), e dai tubolari di sostegno in acciaio (11), garantisce la stabilizzazione dell’ala superiore (10c) del profilato di acciaio (10), comportando un incremento della capacità portante del profilato (10). The photovoltaic surface, consisting of the panels (PV), the relative aluminum connections (80, 82), and the steel support tubes (11), guarantees the stabilization of the upper wing (10c) of the steel profile (10) , resulting in an increase in the bearing capacity of the section (10).
L’impermeabilizzazione della superficie fotovoltaica (C) è garantita da guarnizioni (83) interposte fra i pannelli fotovoltaici (PV) ed i listelli (80 e 82) in direzione longitudinale e tra pannello e pannello in direzione trasversale . Si richiama ora l’attenzione sull’ intercapedine d’aria (D) che resta fra lo strato di coibentazione (B) inferiore ed il mantello di copertura superiore (C), dal momento che detta intercapedine assicura un ‘elevata ventilazione della superficie inferiore dei pannelli fotovoltaici (PV) , particolarmente ricercata in presenza di elevate temperature ambientali al fine di raffreddare detta superfici. The waterproofing of the photovoltaic surface (C) is guaranteed by gaskets (83) interposed between the photovoltaic panels (PV) and the strips (80 and 82) in the longitudinal direction and between the panel and the panel in the transverse direction. Attention is now drawn to the air gap (D) that remains between the lower insulation layer (B) and the upper covering mantle (C), since said gap ensures high ventilation of the lower surface of the photovoltaic panels (PV), particularly sought after in the presence of high ambient temperatures in order to cool said surfaces.
In presenza di basse temperature ambientali, invece, la stessa intercapedine, opportunamente tamponata perimetralmente, si trasforma in un vano d’aria termoisolante, che contribuisce ad incrementare l’effetto di coibentazione dello strato (B) . In the presence of low ambient temperatures, however, the same cavity, suitably buffered around the perimeter, turns into a heat-insulating air compartment, which helps to increase the insulation effect of the layer (B).
Con particolare riferimento alle figg. 4a e 4B a quest’ultimo proposito si fa presente che in corrispondenza dei lati trasversali della coppella (1) sono montati schermi di tamponatura (90) ribaltabili, del tipo delle finestre a vasistas , per cui diventa possibile favorire od inibire la ventilazione attraverso detta intercapedine (D) . With particular reference to figs. 4a and 4B with regard to the latter, it should be noted that in correspondence with the transversal sides of the cup (1), tilting infill screens (90) are mounted, of the type of transom windows, so that it becomes possible to favor or inhibit ventilation through said interspace (D).
In definitiva si può dire che la coppella a guscio (1) secondo il trovato rappresenta anche una soluzione al problema del risparmio energetico , dal momento che la sua struttura a guscio è in grado di regolare contemporaneamente : Ultimately it can be said that the shell cup (1) according to the invention also represents a solution to the problem of energy saving, since its shell structure is capable of simultaneously regulating:
- le condizioni termo-igrometriche all 'interno dell 'edificio - le condizioni di funzionamento dei pannelli fotovoltaici (PV), evitando il loro surriscaldamento mediante aerazione naturale della zona interna del guscio . - the thermo-hygrometric conditions inside the building - the operating conditions of the photovoltaic panels (PV), avoiding their overheating through natural ventilation of the internal area of the shell.
Si precisa che l’interasse fra i profilati longitudinali (10) è praticamente pari alla larghezza dei pannelli fotovoltaici (PV), mentre la lunghezza (L) della coppella (1) varia con Γ inclinazione dello shed e con il passo dei pilastri (P) edificio come è facile intuire dalla osservazione di figura 5, che mostra come la coppella (1) venga fissata sopra e a cavallo delle travi (T) sorrette dai pilastri (P) . It should be noted that the distance between the longitudinal profiles (10) is practically equal to the width of the photovoltaic panels (PV), while the length (L) of the cup (1) varies with Γ inclination of the shed and with the pitch of the pillars (P ) building as it is easy to guess from the observation of figure 5, which shows how the cup (1) is fixed above and astride the beams (T) supported by the pillars (P).
Un’ultima precisazione va fatta con riferimento alle modalità di installazione del manto di copertura (C) al di sopra della coppella (1) in parola. A final clarification should be made with reference to the methods of installation of the roof covering (C) above the cup (1) in question.
Come evidenziato nelle figg 1 e 2 , la coppella prefabbricata (1) incorpora lo strato inferiore di coibentazione (B) e la sovrastante struttura portante (A) , completa di traverse trasversali (11) , fissate a cavallo della coppia parallela di profilati longitudinali (10). As shown in figs 1 and 2, the prefabricated cup (1) incorporates the lower layer of insulation (B) and the overlying load-bearing structure (A), complete with transverse crosspieces (11), fixed astride the parallel pair of longitudinal profiles ( 10).
Detta coppella prefabbricata (1) incorpora anche la serie distanziata di profilati tubolari (60) che corrono al di sotto del pannello sandwich (20) . Said prefabricated cup (1) also incorporates the spaced series of tubular profiles (60) which run underneath the sandwich panel (20).
Per puri motivi di risparmio di tempo e di mano d’opera , il completamento di ciascuna coppella (1) con i pannelli fotovoltaici (PV) di copertura avviene direttamente sul cantiere di costruzione dell’edificio. For purely reasons of saving time and manpower, the completion of each cup (1) with the roofing photovoltaic panels (PV) takes place directly on the construction site of the building.
Sempre con riferimento alle figg. 1 e 2 si fa come ai lati longitudinali della coppella (1) debordi un tratto (23) di detto pannello di coibentazione (20). Again with reference to figs. 1 and 2 a section (23) of said insulation panel (20) protrudes from the longitudinal sides of the cup (1).
Ciò significa che affiancando due coppelle prefabbricate (1) si deve fare attenzione affinché la coppia interfacciata di tratti debordanti (23), rispettivamente appartenenti alla prima ed alla seconda coppella, vadano a combaciare esattamente fra loro, proprio come mostrato in fig. 6. This means that by placing two prefabricated cupels (1) side by side, care must be taken so that the interfaced pair of protruding sections (23), respectively belonging to the first and second cupels, fit together exactly, just as shown in fig. 6.
In una simile circostanza viene a determinarsi fra la coppia interfacciata di profilati longitudinali (10), rispettivamente appartenenti alla prima ed alla seconda coppella, uno spazio (S) identico a quello che intercorre fra coppia di profilati longitudinali (10) di ciascun coppella (1) e come tale idoneo ad essere tamponato superiormente con pannelli fotovoltaici (PV). In such a circumstance, a space (S) identical to that between the pair of longitudinal profiles (10) of each cup (1 ) and as such suitable for being buffered at the top with photovoltaic (PV) panels.
In questa prospettiva fra la coppia interfacciata di profilati longitudinali (10), rispettivamente appartenenti alla prima ed alla seconda coppella, vengono distese traverse tubolari (11 ’) destinate ad allinearsi con le traverse tubolari (11) in dotazione a ciascuna coppella prefabbricata. In this perspective, between the interfaced pair of longitudinal profiles (10), respectively belonging to the first and second cupels, tubular crosspieces (11 ') are laid out to align with the tubular crosspieces (11) supplied with each prefabricated cup.
Una volta ultimato il montaggio di tutti i pannelli fotovoltaici, la sezione della serie di coppelle (1) affiancate si presenta come mostrato in fig 7. Once the assembly of all the photovoltaic panels has been completed, the section of the series of cupels (1) side by side appears as shown in fig 7.
