Questa pubblicazione presenta il problema che ci sia la necessit? di avere due tipi di pannelli differenti adiacenti il che richiede in pianificazione in loco inoltre uno smontaggio dopo il montaggio complicato. This publication presents the problem that there is a need to have two different panel types adjacent which requires on-site planning and complicated disassembly after assembly.
Inoltre i pannelli e sistemi precedentemente descritti presentano una densit? relativamente alta ed dimensioni rilevanti questo comporta un carico della struttura ed inoltre una perdita di spazio interno che pu? comportare un peggioramento del clima di una stanza o simile. Furthermore, the panels and systems previously described have a density? relatively high and relevant dimensions this involves a load of the structure and also a loss of internal space that can? lead to a worsening of the climate in a room or the like.
Lo scopo della presente invenzione ? di realizzare un sistema fonoassorbente che assorba le differenti frequenze e che abbia una superficie uniforme e sia facilmente installabile in loco senza dovere adattare il sistema alle specifiche del luogo e presenta peso e dimensioni ridotti in particolare uno spessore ridotto. Questo scopo viene raggiunto da un sistema secondo la parte caratterizzante della rivendicazione 1. The purpose of the present invention ? to create a sound-absorbing system that absorbs the different frequencies and that has a uniform surface and can be easily installed on site without having to adapt the system to the specifics of the place and has reduced weight and dimensions, in particular a reduced thickness. This object is achieved by a system according to the characterizing part of claim 1.
Il sistema secondo l?invenzione ? composto da un telaio di supporto realizzato da un profilato metallico disposto su una superfice preferibilmente. Il telaio di supporto ? costituito da almeno due traverse disposte sostanzialmente parallele fra loro ad una distanza dai 40 a 75 cm fra loro e il telaio ? fissato ad una superficie interna di un edificio, al telaio sono fissati dei pannelli, presentanti sulla superficie superiore orientata verso l?interno dello spazio sul lato opposto al telaio un rivestimento. Questo rivestimento ? realizzato mediante un composto formato per m<2 >dai 300-700g miscela di cotone e da 4 ai 6 litri di acqua, in cui la miscela di cotone comprende fra il 80-95% fibre di cottone o un composto fra fibre di cotone e fibre di legno il 80-95%e fra 5-18% cellulosa con lunghezza di fibra da 0,2-4 mm. The system according to the invention? composed of a support frame made of a metal profile arranged on a surface preferably. The support frame? consisting of at least two crosspieces arranged substantially parallel to each other at a distance of 40 to 75 cm between them and the frame ? fixed to an internal surface of a building, panels are fixed to the frame, having a coating on the upper surface oriented towards the interior of the space on the side opposite the frame. This coating? made by a compound formed per m<2 > of 300-700g cotton blend and 4 to 6 liters of water, wherein the cotton blend comprises between 80-95% cotton fibers or a compound between cotton fibers and wood fibers 80-95% and between 5-18% cellulose with fiber length from 0,2-4 mm.
I pannelli sono realizzati preferibilmente in poliestere e presentano uno spessore fra 9-24. The panels are preferably made of polyester and have a thickness between 9-24.
I pannelli vengono fissati ad un telaio per esempio metallico profilato o legno. L?interspazio fra le traverse del telaio ? dai 40 ai 75 cm. In questo modo il pannello rivestito pu? flettersi e vibrare per assorbire meglio il suono. The panels are fixed to a frame, for example profiled metal or wood. The space between the cross members of the frame? from 40 to 75 cm. In this way the coated panel can? flex and vibrate to better absorb sound.
Mediante le traverse del telaio i pannelli sono distanziati dalla superficie. In questo modo fra le traverse del telaio si forma una camera che pu? essere riempita anche solo parzialmente mediante pannelli in fibre di poliestere, pannelli in fibre di vetro, pannelli in fibre di legno. By means of the frame crossbars the panels are spaced from the surface. In this way a chamber is formed between the crosspieces of the frame which can be filled, even if only partially, with polyester fiber panels, glass fiber panels, wood fiber panels.
Il telaio che compone il sistema pu? essere anche parte del controsoffitto. The frame that makes up the system can? also be part of the countertop.
Qui di seguito viene descritto un sistema secondo l'invenzione con riferimento ai disegni in modo non limitativo: la Figura 1 mostra una sezione di un sistema secondo l?invenzione, la Figura 2 mostra una vista frontale del sistema secondo l?invenzione parzialmente montato, la Figura 3 mostra una vista frontale del sistema secondo l?invenzione parzialmente montato in una seconda forma di realizzazione, la Figura 4 mostra una sezione di un sistema secondo l?invenzione in una seconda forma di realizzazione, la Figura 5 mostra un grafico dell?assorbimento del sistema secondo l?invenzione, e la Figura 6 mostra un grafico dell?assorbimento del sistema secondo l?invenzione in una seconda varianti in cui il sistema ? fissato distanziato dalla superficie. In the following, a system according to the invention is described in a non-limiting manner with reference to the drawings: Figure 1 shows a section through a system according to the invention, Figure 2 shows a front view of the partially assembled system according to the invention, Figure 3 shows a front view of the system according to the invention partially assembled in a second embodiment, Figure 4 shows a section through a system according to the invention in a second embodiment, Figure 5 shows a graph of the absorption of the system according to the invention, and Figure 6 shows an absorption graph of the system according to the invention in a second variant in which the system ? fixed away from the surface.
Nella Figura 1 con il numero di riferimento 100 viene indicato un sistema fonoassorbente costruttivo che viene fissato a una superficie interna di un edificio 200 in particolare un soffitto. Il sistema secondo l?invenzione comprende una traversa 102 che pu? essere collegata a un controsoffitto conformato da materiale isolante 202, profilati 101 e un interspazio 201 come illustrato in Figura 1 e 2 nel grafico di Figura 6 ? indicato il comportamento nel caso in cui i pannelli presentano una distanza di circa 20 cm dal soffitto/sono appesi a circa 20 cm di distanza. In Figure 1, the reference numeral 100 designates a constructive sound-absorbing system which is fixed to an internal surface of a building 200, in particular a ceiling. The system according to the invention comprises a crosspiece 102 which can? be connected to a false ceiling formed by insulating material 202, profiles 101 and a gap 201 as illustrated in Figures 1 and 2 in the graph of Figure 6 ? the behavior is indicated if the panels have a distance of about 20 cm from the ceiling/are hung at a distance of about 20 cm.
Il sistema secondo l?invenzione 100 comprende almeno due traverse 102 sostanzialmente parallele fra loro che formano fra loro uno interspazio 105 che viene coperto da un pannello 103 fissato ai suoi bordi alle traverse 102. Il pannello 103 presenta in modo vantaggioso uno spessore i 5 e i 30 mm in modo preferito fra i 9 mm e i 24 mm. Le traverse 102 sono distanziate fra loro dai 40 cm ai 75 cm. In questo modo il pannello 103 pu? flettersi in entrambe le direzioni. The system 100 according to the invention comprises at least two crosspieces 102 substantially parallel to each other which form an interspace 105 between them which is covered by a panel 103 fixed at its edges to the crosspieces 102. The panel 103 advantageously has a thickness i 5 and i 30 mm preferably between 9 mm and 24 mm. The crosspieces 102 are spaced apart from 40 cm to 75 cm. In this way the panel 103 can? bend in both directions.
L?interspazio 105 pu? essere vuoto come illustrato nella prima forma di realizzazione o pu? essere riempito con materiale di riempimento 116 come illustrato nella seconda forma di realizzazione nella figura 4. The interspace 105 pu? be empty as shown in the first embodiment or pu? be filled with filling material 116 as illustrated in the second embodiment in Figure 4.
Il pannello 103 viene rivestito mediante uno rivestimento costituito da un composto formato per m<2 >dai 300-700g miscela di cottone e da 4 ai 6 litri di acqua, in cui la miscela di cottone comprende fra il 80-95% fibre di cottone o un composto fra fibre di cotone e fibre di legno il 80-95% e fra 5-18% cellulosa con lunghezza di fibra da 0,2-4 mm. Panel 103 is coated with a coating consisting of a compound formed per m<2> of 300-700g cotton blend and 4 to 6 liters of water, wherein the cotton blend comprises between 80-95% cotton fibers or a compound between 80-95% cotton fibers and 80-95% wood fibers and between 5-18% cellulose with fiber length from 0,2-4 mm.
Nella prima forma di realizzazione le traverse 102 sono disposte a croce e formano interspazi rettangolari. Per? le traverse 102 laterali non sono necessarie. In the first embodiment the crosspieces 102 are arranged in a cross and form rectangular interspaces. For? the lateral crosspieces 102 are not necessary.
I pannelli 103 possono essere collegati alle traverse 102 per mezzo di viti come illustrato nella figura 1 o in una ulteriore forma di realizzazione per esempio per mezzo di magneti posti sui pannelli 103. In questo modo anche in un secondo momento un distaccamento dei pannelli fonoassorbenti 103 dalla struttura ? facile e veloce. Questo pu? essere richiesto se per esempio elementi elettrici o altri elementi devono essere sostituiti posteriormente al sistema fonoassorbente. The panels 103 can be connected to the crosspieces 102 by means of screws as illustrated in figure 1 or in a further embodiment for example by means of magnets placed on the panels 103. In this way also at a later time a detachment of the sound absorbing panels 103 from the structure? easy and fast. This can be required if for example electrical elements or other elements have to be replaced after the soundproofing system.
Nelle figure 3 e 4 ? illustrata una seconda forma di realizzazione in cui le traverse 112 sono fissate direttamente sulla superficie dell?edificio 200. Anche in questo caso le traverse 112 sono disposte distanziate fra loro sostanzialmente parallele fra i 40 cm e i 75 cm. Per garantire un migliore smorzamento del suono sono previsti pannelli 116 formati da fibre di poliestere, pannelli a fibra di vetro, pannelli a fibre di legno. Per? fra il pannello superficiale 113 rivestito mediante il composto 114 e il materiale e/o il pannello di riempimento 116 ? sempre infrapposto uno spazio 115 che permette che il panello superficiale 113 si possa inflettere e oscillare. In figures 3 and 4 ? a second embodiment is illustrated in which the crosspieces 112 are fixed directly to the surface of the building 200. Also in this case the crosspieces 112 are arranged spaced substantially parallel to each other between 40 cm and 75 cm. To ensure better sound damping, panels 116 formed by polyester fibers, glass fiber panels, wood fiber panels are provided. For? between the surface board 113 coated by the compound 114 and the material and/or the filler board 116 ? always interposed a space 115 which allows the surface panel 113 to bend and oscillate.
Nella figura 5 ? illustrato un grafico in cui viene indicato con X l?andamento dell?assorbimento del suono a seconda delle frequenze con un sistema secondo l?invenzione che presenta uno spessore minimo. In figure 5 ? A graph is shown in which the trend of sound absorption according to frequencies is indicated with X with a system according to the invention which has a minimum thickness.
Vantaggiosamente la distanza fra il collegamento delle traverse 112 con l?edificio e il pannello superficiale 113 rivestito con il composto 114 presenta uno spessore inferiore ai 5 cm preferibilmente al di sotto dei 4,5 cm. Advantageously, the distance between the connection of the crosspieces 112 with the building and the surface panel 113 covered with the compound 114 has a thickness of less than 5 cm, preferably less than 4.5 cm.
E? infine chiaro che al sistema fonoassorbente costruttivo descritto possono essere applicate aggiunte, modifiche o varianti ovvie per un tecnico del ramo senza per questo fuoriuscire dall?ambito di tutela fornito dalle rivendicazioni annesse. AND? finally, it is clear that additions, modifications or variations which are obvious to a person skilled in the art can be applied to the sound-absorbing constructive system described without thereby departing from the scope of protection provided by the appended claims.
