Abstract
E' un nuovo pannello fonoassorbente costituito da un pannello rigido di materiale fibroso, preferibilmente lana di legno, accoppiato con uno strato di materiale espanso, preferibilmente resina poliuretanica, fra i quali รจ interposto un foglio metallico o in materiale plastico pesante, preferibilmente piombo. Il nuovo pannello ha una elevata resistenza meccanica e assorbe una vasta gamma di frequenze sonore.It is a new sound-absorbing panel consisting of a rigid panel of fibrous material, preferably wood wool, coupled with a layer of foam material, preferably polyurethane resin, between which a sheet of metal or heavy plastic material, preferably lead, is interposed. The new panel has a high mechanical resistance and absorbs a wide range of sound frequencies.
Description
PANNELLO FONOASSORBENTE COMPOSITO COMPOSITE SOUND ABSORBING PANEL
DESCRIZIONE DESCRIPTION
La presente invenzione ? attinente al settore dei rivestimenti atti a ridurre la trasmissione e la riflessione delle onde sonore. The present invention? pertaining to the field of coatings designed to reduce the transmission and reflection of sound waves.
Attualmente per ridurre la trasmissione e la riflessione del rumore vengono utilizzati sia la resina plastica espansa oppure lana di roccia o lana di vetro. Currently, to reduce the transmission and reflection of noise, both foamed plastic resin or rock wool or glass wool are used.
La resina espansa ? prodotta in pannelli talvolta accoppiati con fogli di cartone-gesso, dotati di lamierino, o strati di legno che vengono applicati ai soffitti o alle pareti. The foam resin? produced in panels sometimes coupled with cardboard-gypsum sheets, equipped with sheet metal, or layers of wood that are applied to the ceilings or walls.
La lana di roccia e la lana di vetro sono prodotte in materassini non rigidi ed anche in pannelli rigidi . Rock wool and glass wool are produced in non-rigid mattresses and also in rigid panels.
Negli edifici i pannelli ed i materassini vengono anche posti fra due pareti sottili in laterizio al fine di ridurre la trasmissione del rumore fra stanze adiacenti. In buildings, panels and mats are also placed between two thin brick walls in order to reduce the transmission of noise between adjacent rooms.
Tali pannelli e materassini sono ottimi per assorbire i rumori alle frequenze medio-alte ma presentano alcuni inconvenienti. I pannelli di materiale plastico espanso hanno un buon assorbimento ed hanno una discreta resistenza alla compressione mentre i materassini di lana di roccia o di vetro hanno una pessima resistenza meccanica; entrambi, pannelli e materassini, hanno uno scarso potere fonoisolante alle medie ed alle basse frequenze e necessitano di un adeguato numero di elementi di fissaggio che costituiscono ponti acustici trasmettendo quindi parte del rumore. These panels and mats are excellent for absorbing noises at medium-high frequencies but have some drawbacks. The panels of expanded plastic material have a good absorption and have a good resistance to compression while the rock wool or glass mats have a very bad mechanical resistance; both panels and mats have a poor soundproofing power at medium and low frequencies and require an adequate number of fixing elements which constitute acoustic bridges, thus transmitting part of the noise.
Per ovviare a tutti i suddetti inconvenienti si ? studiato e realizzato un nuovo tipo di pannello fonoassorbente e fonoisolante composto da materiali diversi . To overcome all the aforementioned drawbacks, yes? designed and built a new type of sound-absorbing and sound-insulating panel made up of different materials.
Il nuovo pannello ? costituito dall'accoppiamento di un pannello rigido fibroso con uno strato di materiale plastico espanso fra i quali ? interposta una lamina metallica o di materiale plastico pesante . The new panel? consisting of the coupling of a rigid fibrous panel with a layer of expanded plastic material between which? interposed with a metal sheet or a heavy plastic material.
Il pannello rigido fibroso ? costituito preferibilmente da lana di legno oppure da lana di roccia ad altissima densit?. The fibrous rigid panel? preferably made of wood wool or very high density rock wool.
Lo strato di materiale plastico espanso ? prefer?bilmente costituito da resina poliuretanica espansa, oppure da altri materiali simili. The layer of expanded plastic material? preferably constituted by expanded polyurethane resin, or by other similar materials.
La lamina rigida interposta ? preferibilmente costituita da un foglio di piombo, una lastra di polivinilcloruro (PVC) caricata con opportuni additivi, uno strato di gomma miscelata con piombo o altri materiali idonei. The interposed rigid sheet? preferably consisting of a lead sheet, a polyvinyl chloride (PVC) sheet loaded with suitable additives, a layer of rubber mixed with lead or other suitable materials.
L'abbinamento ottimale preferito fra i materiali suddetti ? composto da un pannello di lana di legno di qualche centimetro di spessore accoppiato con uno strato di resina espansa fra i quali ? interposto un foglio di piombo. The preferred optimal combination of the above materials? composed of a panel of wood wool of a few centimeters thick coupled with a layer of expanded resin between which? interposed a sheet of lead.
Il pannello cos? costituito permette di assorbire ed attenuare la trasmissione diuna pi? vasta gamma di rumori, dalle basse alle alte frequenze, pu? essere utilizzato su superfici verticali, orizontali o inclinate, ? autoportante e non ha bisogno di supporti aggiuntivi per mantenere la forma, necessita di pochi elementi di fissaggio riducendo notevolmente i ponti sonori. The panel so? constituted allows to absorb and attenuate the transmission of a pi? wide range of noises, from low to high frequencies, can? be used on vertical, horizontal or inclined surfaces,? self-supporting and does not need additional supports to maintain the shape, it requires few fixing elements, considerably reducing sound bridges.
Nella tavola allegata viene presentato, a titolo esemplificativo e non limitativo, una pratica realizzazione del trovato. In the attached table, a practical embodiment of the invention is presented by way of non-limiting example.
E' rappresentata una sezione verticale del pannello in cui sono chiaramente visibili il pannello rigido fibroso (1), il foglio di piombo (2) e lo s A vertical section of the panel is shown in which the rigid fibrous panel (1), the lead sheet (2) and the s
materiale espanso (3). foam material (3).
Queste sono le modalit? schematiche sufficienti alla persona esperta per realizzare il trovato, di conseguenza, in concreta applicazione potranno esservi delle varianti senza pregiudizio alla sostanza del concetto innovativo. These are the modalities? schematic diagrams sufficient for the skilled person to carry out the invention; consequently, in concrete application there may be variations without prejudice to the substance of the innovative concept.
Pertanto con riferimento alla descrizione che precede e alla tavola acclusa si esprimono le seguenti rivendicazioni. Therefore, with reference to the preceding description and to the attached table, the following claims are expressed.
