DESCRIZIONE DI MODELLO D'UTILITÀ' di UTILITY MODEL DESCRIPTION of
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
STATO ATTUALE DELLA TECNICA CURRENT STATE OF THE TECHNIQUE
Le attuali tecnologie produttive realizzano un pannello di tipo " sandwich " costituito da tre componenti Current production technologies produce a "sandwich" type panel consisting of three components
a ) Profilo esterno grecato ed irrigidito in acciaio zinco prevermciato , a) Corrugated and stiffened external profile in pre-coated zinc steel,
b ) Strato coibente in resina poliuretanica ( PUR ), b) Insulating layer in polyurethane resin (PUR),
c ) Rivestimento superficiale lato interno in alluminio centesimale sp 0,08 mm , oppure in cartonfeltro bitumato oppure in materiale noh metallico c) Surface coating on the internal side in centesimal aluminum 0.08 mm thick, or in bitumen felt paper or in metal noh material
Il componente a) è monolitico con il componente b) ,ll componente b) è monolitico con il componente c) mentre i componenti a) - c) non sono tra loro in contatto Premesso che Component a) is monolithic with component b), component b) is monolithic with component c) while components a) - c) are not in contact with each other.
1) L' acciaio del profilo grecato è di qualità SD GD+Z , con carico unitario mimmo di snervamento pari a 220 N/mm2 , 1) The steel of the corrugated profile is of SD GD + Z quality, with minimum unit yield strength equal to 220 N / mm2,
2) La schiuma poliuretanica ha un carico di compressione di 0,32 N/mm2 , 2) Polyurethane foam has a compression load of 0.32 N / mm2,
3 ) Per una vite Φ 6 di classe 46 il precarico miimorichiesto è di 340 kg , 3) For a screw Φ 6 of class 46 the required preload is 340 kg,
la geometria attualmente così configurata non conferisce al pannello una ottimale resistenza alla compressione per via della depressione procurata prima sul foglio di alluminio e sullo strato coibente , poi , dai serraggi degli elementi di fissaggio e in particolare da eventuali camminamenti the geometry currently configured in this way does not give the panel an optimal resistance to compression due to the depression generated first on the aluminum sheet and on the insulating layer, then, by the tightening of the fastening elements and in particular by any walkways
Tali fissaggi , infatti , devono resistere all'azione di depressione del vento ed agli effetti delle dilatazioni termiche These fasteners, in fact, must resist the action of wind depression and the effects of thermal expansion
La deformazione così causata procura nel tempo un allentamento del fissaggio tra vite,cappellotto e lamiera The deformation thus caused causes a loosening of the fastening between the screw, cap and sheet metal over time
Conseguentemente le onde del profilo , nelle zone di sovrapposizione , essendosi allentate si sollevano procurando la mancanza della tenuta meccanica allo strappo e della tenuta idraulica del giunto dando così luogo ad infiltrazioni d'acqua con inevitabile deterioramento del listello sottostante il pannello Consequently, the waves of the profile, in the overlapping areas, having loosened, rise causing the lack of the mechanical seal against the tear and the hydraulic seal of the joint, thus giving rise to water infiltrations with inevitable deterioration of the strip below the panel
Inoltre i piani di contatto non essendo più adeguatamente vincolati nei punti di giunzione non sono tra loro collaboranti inficiando così la resistenza meccanica della copertura Furthermore, since the contact surfaces are no longer adequately constrained at the junction points, they do not cooperate with each other, thus affecting the mechanical resistance of the roof.
OBIETTIVO DELL'INNOVAZIONE GOAL OF INNOVATION
La nuova configurazione geometrica data al profilo terminale del pannello considerato causa la maggiorazione del modulo di resistenza adesso costituito da un profilo assimilabile ad un C in lamiera di acciaio al cui interno vive il materiale coibente Tale sezione conferisce un incremento sostanziale alla originaria resistenza meccanica assicurando in tal modo la pedonabilità sulla copertura ed eliminando qualsiasi piano depresso potenziale accumulo di acqua meteorica The new geometric configuration given to the terminal profile of the considered panel causes the increase of the resistance module now consisting of a profile similar to a C in steel sheet inside which the insulating material lives. thus the walkability on the roof and eliminating any depressed floor potential accumulation of rainwater

ANALISI DEL RISULTATO RESULT ANALYSIS
Le modifiche realizzate su di un pannello non hanno dato luogo a cedimenti strutturali significativi pur adottando l'identica tecnologia di montaggio ed utilizzando gli stessi parametri di fissaggio ovvero uguali componenti meccanici ( vite , rondella , guarnizioni ) ed immutate coppie di serraggio The modifications carried out on a panel did not give rise to significant structural failures although adopting the same assembly technology and using the same fixing parameters or the same mechanical components (screw, washer, gaskets) and unchanged tightening torques
Le modifiche realizzate su di un pannello non hanno dato luogo a cedimenti strutturali The modifications made on a panel did not give rise to structural failures
