Campo della tecnica field of technique
La presente invenzione opera nell?ambito della produzione di elementi fonoassorbenti, e, in particolare, blocchi in cemento armato dotati di una faccia fonoassorbente appositamente sagomata. Ancora pi? specificatamente, l?oggetto della presente invenzione riguarda blocchi in cemento con almeno una faccia fonoassorbente riutilizzabili, riciclabili e sagomati superiormente in modo tale che siano facilmente assemblabili, a secco, tra di loro. The present invention operates in the field of the production of sound-absorbing elements, and, in particular, reinforced concrete blocks provided with a specially shaped sound-absorbing face. even more specifically, the object of the present invention relates to concrete blocks with at least one sound-absorbing face that are reusable, recyclable and shaped at the top in such a way that they can be easily assembled dry together.
Arte nota Known art
Oggi numerosi sono i sistemi e i mezzi utilizzati per l?assorbimento e l?attenuazione del rumore, ma quasi sempre applicati in aree chiuse, cio? in quello che pu? essere considerato un ambito domestico/abitativo. Today there are numerous systems and means used for the absorption and attenuation of noise, but almost always applied in closed areas, i.e. in closed areas. in what can be considered a domestic/residential environment.
Soprattutto negli ultimi anni la ricerca si sta spingendo verso soluzioni che vadano sempre pi? a limitare l?inquinamento acustico prodotto da cantieri, che affligge ormai quotidianamente sia l?ambito urbano che extraurbano. Especially in recent years, research is moving towards solutions that are increasingly to limit the noise pollution produced by construction sites, which now afflicts both urban and extra-urban areas on a daily basis.
Un esempio ? il prodotto oggetto della domanda di brevetto CN102094395A. Esso rivendica un pannello fonoassorbente per barriere acustiche in cemento, caratterizzato dal fatto di comprendere uno strato fonoisolante, uno strato di intercapedine e uno strato fonoassorbente; lo strato di isolamento acustico ? un telaio sagomato con depressioni e lo strato di assorbimento acustico ? disposto sullo strato di isolamento. Sulla superficie del telaio dello strato acustico, ? presente uno strato di cavit? tra lo strato di assorbimento acustico e lo strato di isolamento acustico; lo strato di assorbimento acustico possiede, inoltre, un foro circolare che amplifica l?effetto assorbente. An example ? the product covered by the patent application CN102094395A. It claims a sound-absorbing panel for concrete acoustic barriers, characterized in that it comprises a sound-insulating layer, a cavity layer and a sound-absorbing layer; the soundproofing layer? a contoured frame with depressions and the sound absorption layer ? placed on the insulation layer. On the surface of the acoustic layer frame, ? present a layer of cavities? between the sound absorption layer and the sound insulation layer; the sound absorption layer also has a circular hole which amplifies the absorption effect.
Le barriere acustiche, tuttavia, sono limitate in alcuni ambiti, infatti, vengono utilizzate principalmente per l?isolamento acustico e la riduzione del rumore nei trasporti e nelle strutture come superstrade, strade composite sopraelevate, rotaie leggere urbane e ferrovie. Acoustic barriers, however, are limited in some areas, in fact, they are mainly used for sound insulation and noise reduction in transport and structures such as expressways, elevated composite roads, urban light rails and railways.
Un altro brevetto ? ES2046931A2. Questo ulteriore documento si riferisce ad un pannello in conglomerato cementizio fonoassorbente e ad un procedimento per la sua fabbricazione, la cui caratteristica fondamentale ? quella di presentare, almeno su una sua superficie, aperture verso l?esterno della sua superficie e comunicanti internamente con camere di risonanza, in modo tale da direzionare quella superficie verso un fronte di propagazione delle onde acustiche. In questo modo si ottiene un assorbimento o attenuazione acustica nel campo delle frequenze di quella sorgente di rumore di propagazione delle onde acustiche. Il pannello pu? avere ampiezza maggiore o minore e formare moduli che possono essere disposti collateralmente ad altri e formare cos? una barriera o addirittura una piattaforma prefabbricata; esso pu? persino fungere da base ferroviaria su cui verranno logicamente disposte le rotaie. Tale pannello presenta un assemblaggio laborioso e dispendioso in termini di tempo ed economicamente: in primo luogo viene predisposta una cassaforma rettangolare, con due stampi all?interno; successivamente viene eseguito un getto di calcestruzzo su una delle scatole o stampi, al fine di ottenere una prima lastra, che sar? dotata di una serie di intercapedini generate con elementi metallici che successivamente andranno rimossi; quindi una delle estremit? di una serie di elementi metallici viene immersa in detto getto di calcestruzzo, che andranno a determinare i mezzi di collegamento con un altro; i suddetti elementi metallici di riempimento vengono quindi sottratti, riempiendo successivamente le cavit? con materiale fonoassorbente poroso, quale argilla espansa. Il calcestruzzo viene colato nel secondo cassone o stampo, ottenendo una seconda lastra; infine, il primo stampo viene ribaltato sul secondo, effettuando la sovrapposizione di entrambe le lastre e la penetrazione nel calcestruzzo fresco degli elementi metallici di giunzione, con la particolarit? che in quest?ultima fase i fori della seconda lastra sono posizionati in corrispondenza delle cavit? esistenti nel primo. Another patent? ES2046931A2. This further document refers to a sound-absorbing cement conglomerate panel and to a process for its manufacture, the main characteristic of which is ? that of presenting, at least on one of its surfaces, openings towards the outside of its surface and communicating internally with resonance chambers, so as to direct that surface towards a propagation front of the acoustic waves. In this way, acoustic absorption or attenuation is obtained in the frequency range of that source of acoustic wave propagation noise. The panel can have greater or lesser width and form modules that can be arranged side by side to others and thus form? a barrier or even a prefabricated platform; it can even serve as a railway base on which the rails will logically be laid out. This panel has a laborious and costly assembly in terms of time and money: firstly, a rectangular formwork is prepared, with two molds inside; subsequently a concrete casting is performed on one of the boxes or molds, in order to obtain a first slab, which will be? equipped with a series of cavities generated with metal elements that will subsequently be removed; then one of the extremities? a series of metal elements is immersed in said concrete casting, which will determine the means of connection with another; the aforementioned metal filling elements are then subtracted, subsequently filling the cavities? with porous sound-absorbing material, such as expanded clay. The concrete is poured into the second box or mould, obtaining a second slab; finally, the first mold is overturned onto the second, superimposing both slabs and penetrating the metal joining elements into the fresh concrete, with the particularity of that in this? last phase the holes of the second slab are positioned in correspondence of the cavit? existing in the first.
Scopo della presente domanda di brevetto ? quello di fornire una soluzione economica e riciclabile, atta a risolvere le problematiche di inquinamento acustico provocate dai cantieri urbani ed extraurbani. L?oggetto del presente documento offre un prodotto assemblabile, scomponibile e ricomponibile in base alle esigenze del cantiere e delle eventuali modifiche in corso d?opera: ?, infatti, possibile sfruttare e riutilizzare i blocchi in cemento armato con faccia fonoassorbente, qui presentati, in base alle esigenze stesse del cantiere, sia che esso sia stabile per un determinato tempo, sia che esso modifichi di volta in volta la sua posizione, eliminando o comunque attenuando il rumore all?esterno. Purpose of this patent application? that of providing an economic and recyclable solution, capable of solving the problems of noise pollution caused by urban and extra-urban construction sites. The object of this document offers a product that can be assembled, disassembled and reassembled according to the needs of the construction site and any modifications during construction: it is, in fact, possible to exploit and reuse the reinforced concrete blocks with a sound-absorbing face, presented here, on the basis of the site's own needs, whether it is stable for a certain time, or whether it changes its position from time to time, eliminating or in any case attenuating the noise outside.
Descrizione dell?invenzione Description of the invention
Secondo la presente invenzione viene fornita una soluzione vantaggiosamente economica, riciclabile, riutilizzabile per eliminare l?inquinamento acustico generato dal cantiere attraverso la produzione di blocchi in cemento armato dotati di almeno una faccia frontale fonoassorbente. Tale faccia del blocco ? costituita interamente da materiale fonoassorbente. I materiali fonoassorbenti possono essere di tre tipi: According to the present invention an advantageously economical, recyclable, reusable solution is provided for eliminating the acoustic pollution generated by the construction site through the production of reinforced concrete blocks having at least one sound-absorbing front face. Such a face of the block ? made entirely of sound absorbing material. Sound absorbing materials can be of three types:
- minerale, come lana di vetro o di roccia e le fibre di legno mineralizzate. Tutti materiali porosi che hanno la capacit? di convertire l?energia acustica in calore; - mineral, such as glass or rock wool and mineralized wood fibres. All porous materials that have the ability? to convert acoustic energy into heat;
- vegetale, quali il sughero, argilla espansa o il legno; - vegetable, such as cork, expanded clay or wood;
- sintetico, ovvero i prodotti chimici come il poliuretano espanso, che hanno buone capacit? di eliminazione del rumore. - synthetic, or chemical products such as polyurethane foam, which have good capacity? noise canceling.
Le qualit? fonoassorbenti di questa faccia frontale sono ulteriormente migliorate poich? detta faccia ? appositamente sagomata a facciavista con scanalature preferibilmente a greca o a ?U?. Tali scanalature possono vantaggiosamente essere orizzontali o verticali, adattandosi in base alla richiesta. The qualities? sound absorbing of this front face are further improved since? said face? purposely shaped facing with grooves preferably a Greek or a ?U?. These grooves can advantageously be horizontal or vertical, adapting according to the request.
Trattandosi di blocchi prodotti al fine di offrire un prodotto per la costruzione di strutture fonoassorbenti per cantieri ? prevista la casistica in cui questi blocchi si trovino in posizione angolare: tale casistica prevede l?aggiunta al blocco di un elemento fonoassorbente amovibile realizzato appositamente per le facce laterali di suddetti blocchi. Detto elemento fonoassorbente amovibile ? prodotto secondo le dimensioni esatte della faccia laterale del blocco ed ? agganciabile al blocco attraverso ?alette? poste alle sue estremit? superiore e inferiore: grazie alle alette l?elemento amovibile viene bloccato dalla giustapposizione dei blocchi. Since these are blocks produced in order to offer a product for the construction of sound-absorbing structures for construction sites? the cases in which these blocks are in an angular position are foreseen: this case foresees the addition to the block of a removable sound-absorbing element made specifically for the side faces of the aforementioned blocks. Said removable sound-absorbing element ? produced according to the exact dimensions of the side face of the block and ? attachable to the block through ?wings? placed at its ends? upper and lower: thanks to the flaps, the removable element is blocked by the juxtaposition of the blocks.
Tali blocchi in cemento armato fonoassorbenti sono dotati nella faccia superiore di cunei di forma preferibilmente troncopiramidale, mentre la faccia inferiore ? sagomata secondo il negativo dei cunei suddetti: questa peculiarit? rende i diversi blocchi sovrapponibili e assemblabili tra loro, senza alcun utilizzo di colate di cemento per fissarli. Questa caratteristica oltre ad essere vantaggiosamente economica, rende semplice il montaggio stesso della struttura che si intende creare, comportando notevoli risparmi di tempo. Dal momento che la struttura ? realizzata ?a secco? ? possibile modificare di volta in volta la struttura in base alle esigenze del cantiere, attraverso il semplice smontaggio e rimontaggio dei blocchi. Tale invenzione ? vantaggiosamente utile sia per cantieri stabili nel tempo, che per cantieri il cui obbiettivo prevede uno spostamento in corso d?opera, quali quelli pertinenti il rifacimento del manto stradale e/o scavi per messa in posa di cavi per rete elettrica/fibra ottica. These sound-absorbing reinforced concrete blocks are equipped on the upper face with wedges preferably in the form of a truncated pyramid, while the lower face is ? shaped according to the negative of the aforementioned wedges: this peculiarity? makes the different blocks superimposable and assembled together, without any use of concrete castings to fix them. This characteristic, in addition to being advantageously economical, makes the assembly of the structure to be created simple, resulting in considerable time savings. Since the structure? made ?dry? ? It is possible to modify the structure from time to time according to the needs of the construction site, through the simple disassembly and reassembly of the blocks. Such an invention? advantageously useful both for stable construction sites over time, and for construction sites whose objective involves moving during construction, such as those pertaining to the resurfacing of the road surface and/or excavations for the laying of cables for the electrical/fibre optic network.
La realizzazione della struttura composta da tali blocchi con faccia fonoassorbente prevede un assemblaggio vantaggiosamente rapido ed economico: The construction of the structure made up of these blocks with a sound-absorbing face provides for an advantageously quick and economical assembly:
in primo luogo, viene predisposta una gettata di magrone che funger? da fondazione per l?intera struttura; successivamente viene data forma alla struttura attraverso l?accostamento di blocchi corrispondenti alla base della struttura; infine segue l?assemblaggio a secco/per incastro dei restanti blocchi fino al raggiungimento dell?altezza desiderata, dove detti blocchi sono assemblati in modo sfalsato aumentando cos? le qualit? statiche della struttura. in the first place, a throw of lean meat is prepared which will serve as a foundation for the entire structure; subsequently the structure is given shape through the juxtaposition of blocks corresponding to the base of the structure; finally follows the dry assembly / by interlocking of the remaining blocks until the desired height is reached, where these blocks are assembled in a staggered way, thus increasing? the qualities? statics of the structure.
Una volta completata, la struttura presenter? una parete interna fonoassorbente, rivolta verso il cantiere, e una parete esterna che avr? l?aspetto di una superficie liscia. La parete interna pu?, con l?aggiunta di ganci e mensole, e supporti per la pannellistica, ottimizzare gli spazi previsti dal cantiere. La parete esterna pu? vantaggiosamente essere dipinta, decorata e rivestita, in base alle diverse esigenze; la parete esterna pu? prevedere, anche, supporti per pannelli pubblicitari e di qualsiasi altro genere, come pannelli informativi o cartelli stradali. Once completed, the structure will present? a sound-absorbing internal wall, facing the construction site, and an external wall that will have the appearance of a smooth surface. The internal wall can, with the addition of hooks and shelves, and supports for panels, optimize the space provided by the construction site. The external wall can advantageously be painted, decorated and covered, according to the different needs; the external wall can? provide, also, supports for advertising panels and of any other kind, such as information panels or road signs.
In una delle forme preferite della presente invenzione, la staticit? della struttura ottenuta con l?assemblaggio dei blocchi con faccia fonoassorbente pu? essere migliorata forando verticalmente e/o orizzontalmente tali blocchi e aggiungendo nel foro ottenuto un supporto metallico, come una barra in acciaio. In one of the preferred embodiments of the present invention, the static? of the structure obtained with the assembly of the blocks with sound-absorbing face can? be improved by drilling these blocks vertically and/or horizontally and adding a metal support, such as a steel bar, in the hole obtained.

Said sound-absorbing block in reinforced concrete is presented as an advantageously economic, recyclable, reusable invention to eliminate the acoustic pollution generated by the construction site, eliminating the noise outside. Referring to FIG. 3 shows a sound-absorbing structure 200, entirely composed of said sound-absorbing blocks in reinforced concrete 100 described according to FIGS. 1 and 2. Said sound-absorbing structure provides lean concrete casting 20 suitable for acting as a foundation for the entire sound-absorbing structure 200; the subsequent placing of said blocks 100 above said lean concrete casting 20, corresponding to the base of said sound-absorbing structure 200; subsequently with the dry assembly/by interlocking of the remaining said blocks 100 the desired height is reached, where said blocks 100 are assembled in a staggered manner thus increasing? the qualities? statics of the sound-absorbing structure 200.
Detta struttura fonoassorbente 200 ? caratterizzata dal fatto di avere una parete fonoassorbente interna 21, rivolta verso il cantiere, e una parete esterna liscia 22. Detta parete interna 21 pu?, con l?aggiunta di ganci e mensole, e supporti per la pannellistica, ottimizzare gli spazi previsti dal cantiere. Detta parete esterna liscia 22 pu? vantaggiosamente essere dipinta, decorata e rivestita, in base alle diverse esigenze; detta parete esterna pu? prevedere, anche, supporti per pannelli pubblicitari e di qualsiasi altro genere, come pannelli informativi. Said sound-absorbing structure 200 ? characterized in that it has an internal sound-absorbing wall 21, facing the construction site, and a smooth external wall 22. Said internal wall 21 can, with the addition of hooks and shelves, and supports for panels, optimize the spaces provided by the building site. Said smooth outer wall 22 can advantageously be painted, decorated and covered, according to the different needs; said external wall can? provide, also, supports for advertising panels and of any other kind, such as information panels.
? infine chiaro che all?invenzione fin qui descritta possono essere apportate modifiche, aggiunte o varianti ovvie per un tecnico del ramo, senza per questo fuoriuscire dall?ambito di tutela che ? fornito dalle rivendicazioni annesse. ? finally, it is clear that modifications, additions or variations that are obvious to a person skilled in the art can be made to the invention described up to now, without thereby departing from the scope of protection which ? provided by the appended claims.
