TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

Oggetto della presente domanda di brevetto è un pannello di lamiera grecata da utilizzare principalmente in edilizia ma anche in altri settori quale elemento portante di contenimento del getto di cemento armato per·solai, soppalchi, pareti ed applicazioni similari avente una conformazione particolarmente studiata per ottenere pregevoli risultati qualitativi, economici, estetici e soprattutto una perfetta aderenza e collaborazione al getto di cemento armato. The subject of the present patent application is a corrugated sheet panel to be used mainly in construction but also in other sectors as a load-bearing element for containing the cast of reinforced concrete for floors, mezzanines, walls and similar applications having a shape particularly studied to obtain valuable qualitative, economic, aesthetic results and above all a perfect adherence and collaboration to the reinforced concrete casting.

Il manufatto secondo il trovato è stato in effetti realizzato in seguito ad un attento esame delle problematiche in atto nel settore edile ove è sempre più d’attualità l'esigenza di progettare strutture che siano le più leggere e staticamente le più affidabili possibile; per questo motivo è in atto da anni un processo di collaborazione tra cemento ed acciaio che spazia in tutti i campi dell'edilizia con ottimi risultati. The artifact according to the invention was in fact made following a careful examination of the current problems in the construction sector where the need to design structures that are as light and statically as reliable as possible is increasingly topical; for this reason a process of collaboration between concrete and steel has been underway for years, ranging in all fields of construction with excellent results.

Naturalmente questo processo di amalgama tra cemento ed acciaio comporta la risoluzione di problemi legati in Principal modo alla natura totalmente eterogenea dei due elementi in questione ed il trovato oggetto della presente domanda si ripromette di risolverne alcuni. Naturally, this process of amalgamation between cement and steel involves the resolution of problems principally linked to the totally heterogeneous nature of the two elements in question and the invention which is the subject of the present application promises to solve some of them.

In pratica il trovato è composto unicamente da un pannello di lamiera sagomata che nel gergo comune viene chiamata "grecata" per la caratteristica sagoma della sezione ad onde di forma trapezoidale, alternate a piani lineari, dette appunto "greche". In practice, the invention is composed solely of a shaped sheet metal panel which in common jargon is called "fretted" due to the characteristic shape of the trapezoidal wave section, alternating with linear planes, precisely called "Greek".

Questa lamiera grecata oggetto del trovato si differenzia dalle altre in circolazione destinate anche allo stesso scopo per il fatto di avere delle scanalature longitudinali (a) poste su ogni lato obliquo della forma trapezoidale della greca e di avere delle bugnature (b) intervallate a passo costante longitudinalmente poste sulla base minore della forma trapezoidale della greca. This corrugated sheet object of the invention differs from the others in circulation also intended for the same purpose due to the fact that it has longitudinal grooves (a) placed on each oblique side of the trapezoidal shape of the corrugation and to have bosses (b) spaced at a constant pitch longitudinally placed on the smaller base of the trapezoidal shape of the fret.

Le scanalature longitudinali sono a forma, preferibilmente ma non soltanto, di triangolo rettangolo sporgente dal Lato obliquo della forma trapezoidale della greca e con 1'ipotenusa rivolta verso l'alto, cioè verso la base minore della stessa forma trapezoidale. The longitudinal grooves are in the form, preferably but not only, of a right-angled triangle protruding from the oblique side of the trapezoidal shape of the corrugation and with the hypotenuse facing upwards, ie towards the smaller base of the same trapezoidal shape.

Queste scanalature rappresentano la caratteristica maggiore del trovato in quanto conferiscono allo stesso un'aderenza totale al getto di cemento e ne impediscono ii.distacco nel senso verticale in quanto creano delle asperità molto marcate intorno alle quali fa buona presa il cemento; tra l'altro questo tipo di scanalature riescono anche a contenere eventuali lievi flessioni del getto in quanto la rigidezza del pannello si trasmette integralmente al getto, essendo le due cose unite dalle scanalature predette. These grooves represent the main feature of the invention as they give it total adherence to the concrete cast and prevent it from detaching in the vertical direction as they create very marked asperities around which the cement grips well; among other things, this type of grooves are also able to contain any slight bending of the casting since the stiffness of the panel is fully transmitted to the casting, the two being joined by the aforementioned grooves.

Le bugnature sulla base minori! della forma trapezoidale della greca, possono essere di forma rotonda od ovale come nel disegno allegato oppure anche di altra forma idonea a garantire che, con il getto di cemento che vi si annida tutto intorno, il trovato sia compatto con il cemento e ne sia inibito lo scorrimento e quindi il distacco in senso longitudinale. The rustications on the minor base! of the trapezoidal shape of the corrugation, they can be of round or oval shape as in the attached drawing or also of another shape suitable to ensure that, with the concrete casting that nestles all around it, the invention is compact with the cement and is inhibited sliding and therefore detachment in the longitudinal direction.

Tra l'altro il trovato in oggetto si caratterizza per il sistema di congiungimento tra un pannello e l'altro costituito dai bordi esterni della sezione (d) risalenti, con la stessa inclinazione del lato obliquo della greca, per un tratto pari alla distanza tra la parte piana della greca e la scanalatura longitudinale esistente sul lato obliquo della stessa, in modo che con una leggera pressione si crei una congiunzione ad incastro (c) che migliora notevolmente le caratteristiche statiche del trovato. Among other things, the invention in question is characterized by the joining system between one panel and the other consisting of the external edges of section (d) rising, with the same inclination of the oblique side of the corrugation, for a section equal to the distance between the flat part of the corrugation and the longitudinal groove existing on the oblique side of the same, so that with a slight pressure an interlocking connection (c) is created which considerably improves the static characteristics of the invention.

Naturalmente rispetto ad altri pannelli di lamiera aventi stesse dimensioni, il trovato, grazie alle scanalature, alle bugnature ed al particolare aggancio, offre dei valori statici e delle portate notevol mente superiori in virtù proprio dell'aumentata sezione e dei diversi momenti di inerzia. Naturally, compared to other sheet metal panels having the same dimensions, the invention, thanks to the grooves, the bosses and the particular coupling, offers considerably higher static values and capacities by virtue of the increased section and the different moments of inertia.
