D E S C R I Z I O N E DESCRIPTION
Il presente trovato ha come oggetto un pannello composito strutturale metallico, costituito da due lastre piane accoppiate da una greca mediante incollaggio. The present invention relates to a metallic structural composite panel, consisting of two flat plates coupled by a fret by gluing.
Tali lastre piane possono essere in alluminio, in acciaio ed altri metalli. These flat sheets can be made of aluminum, steel and other metals.
Tradizionalmente, per la realizzazione di pannelli, pareti ed altri elementi fonoassorbenti, si utilizzano opportuni materiali noti per le loro caratteristiche fonoassorbenti. Traditionally, suitable materials known for their sound-absorbing characteristics are used to make panels, walls and other sound-absorbing elements.
I materiali noti con caratteristiche fonoassorbenti presentano vari inconvenienti quali il costo, la difficile lavorazione, un elevato impatto ambientale ed altri problemi legati all'aspetto estetico del materiale stesso che deve essere verniciato o rivestito, secondo l'uso. Known materials with sound-absorbing characteristics have various drawbacks such as cost, difficult processing, high environmental impact and other problems linked to the aesthetic appearance of the material itself to be painted or coated, according to use.
Compito del presente trovato è quello di realizzare una struttura fonoassorbente per la realizzazione di pannelli, pareti ed altri elementi con caratteristiche fonoassorbenti, fabbricato a partire da materia prima economica e non necessariamente avente di per sé caratteristiche fonoassorbenti. The aim of the present invention is to provide a sound-absorbing structure for making panels, walls and other elements with sound-absorbing characteristics, manufactured starting from cheap raw material and not necessarily having sound-absorbing characteristics per se.
Nell'ambito di questo compito, uno scopo del trovato è quello di realizzare una struttura fonoassorbente che possa essere fabbricata con costi di produzione ridotti ed in maniera semplice. Within the scope of this aim, an object of the invention is to provide a sound-absorbing structure which can be manufactured with reduced production costs and in a simple manner.
Un ulteriore scopo è quello di realizzare un pannello che risulti particolarmente rigido e resistente dal punto di vista meccanico. A further object is to provide a panel which is particularly rigid and resistant from a mechanical point of view.
Il pannello fonoassorbente in oggetto può essere prodotto a partire da materiali facilmente reperibili sul mercato e con macchinari già disponibili nel settore. The sound-absorbing panel in question can be produced starting from materials readily available on the market and with machinery already available in the sector.
Un altro scopo del trovato è quello di realizzare un pannello che risulti adatto alla realizzazione di componenti strutturali in svariati settori. Another object of the invention is to provide a panel which is suitable for making structural components in various sectors.
Un ulteriore scopo del trovato è quello di realizzare un pannello avente un peso particolarmente ridotto, in rapporto alle sue prestazioni meccaniche. A further object of the invention is to provide a panel having a particularly low weight, in relation to its mechanical performance.
Un altro scopo è quello di realizzare un pannello che, per le sue peculiari caratteristiche realizzative, sia in grado di assicurare le più ampie garanzie di affidabilità e di sicurezza nell'uso.

This and other purposes, which will be better highlighted below, are achieved by a sound-absorbing structural panel characterized in that it comprises a first and a second sheet-like element connected to each other, so as to be substantially parallel, by means of the interposition of an element of corrugated connection consisting of a corrugated element.
Sul primo elemento lastriforme vengono praticati una doppia serie di fori: una serie di fori verticali ed una serie di fori orizzontali. A double series of holes are drilled on the first sheet-like element: a series of vertical holes and a series of horizontal holes.
La geometria della foratura del primo elemento lastriforme è realizzata in base al principio di risonanza di Hemholtz. The geometry of the drilling of the first sheet-like element is made according to the Hemholtz resonance principle.
La disposizione geometrica dei fori prevede che la serie verticale sia costituita da fori distanziati con un unico passo mentre nella serie orizzontale i fori possono essere da uno ad un massimo di tre anche con passi diversi. The geometric arrangement of the holes provides that the vertical series consists of holes spaced with a single pitch while in the horizontal series the holes can be from one to a maximum of three even with different pitches.
