DESCRIZIONE DI INVENZIONE INDUSTRIALE DESCRIPTION OF INDUSTRIAL INVENTION
Avente per titolo: SISTEMA COSTRUTTIVO COSTITUITO DA ELEMENTI MODULARI IN ACCIAIO SAGOMATI A FREDDO COMPONIBILI PER LA REALIZZAZIONE DI STRUTTURA PORTANTE DI FABBRICATI E RELATIVE MODALITÀ’ DI ASSIEMAGGIO CON COMPONENTI STANDARD Entitled: CONSTRUCTION SYSTEM CONSTRUCTED BY COLD-SHAPED MODULAR STEEL ELEMENTS FOR THE CONSTRUCTION OF THE SUPPORTING STRUCTURE OF BUILDINGS AND RELATED ASSEMBLY METHODS WITH STANDARD COMPONENTS
Il sistema oggetto della domanda di brevetto consiste in una serie di elementi standard costituiti da “elementi asta” e “elementi di collegamento" da combinare assieme secondo schemi modulari al fine di realizzare fabbricati ad uso civile. Gli elementi asta vengono realizzati con dei profilati a C con aletta sagomati a freddo e zincati a caldo (fig. 1), che presentano lunghezze modulari secondo un numero ridotto di serie standard (fig.3: elementi colonna, fig.4: elementi trave, fig.5: elementi per coperture per pendenza 1/2, fig.6: elementi per coperture con pendenza 1/1 o per solai inclinati di 45°), mentre gli elementi di collegamento presentano tipologie standard (e risultano comunque di numero ridotto) in modo da consentire di collegare gli elementi standard senza dover procedere a una progettazione su misura di tali elementi (alcuni esempi sono riportati nelle fig. The system that is the subject of the patent application consists of a series of standard elements consisting of "rod elements" and "connecting elements" to be combined together according to modular schemes in order to create buildings for civil use. C with cold-shaped and hot-dip galvanized fins (fig. 1), which have modular lengths according to a reduced number of standard series (fig. 3: column elements, fig. 4: beam elements, fig. 5: roofing elements for slope 1/2, fig. 6: elements for roofs with a slope of 1/1 or for floors inclined at 45 °), while the connecting elements have standard types (and are in any case small in number) in order to allow the elements to be connected standard without having to carry out a tailor-made design of these elements (some examples are shown in fig.
7÷15). Gli elementi asta risultano realizzabili industrialmente dalla sagomatura a freddo di lamiere di ridotto spessore, mentre la maggior parte degli elementi di collegamento sono costituiti da lamiere dritte o piegate e forate (fig.7-8-9-10), che possono essere realizzate anche in questo caso in modo industriale; il numero di elementi sui quali è necessario l’intervento dell’uomo sono gli elementi saldati che costituiscono le piastre di base e alcuni elementi per il fissaggio dei controventi (fig.11-12-13-14-15), che risultano in numero estremamente limitato rispetto alla globalità degli elementi del fabbricato. 7 ÷ 15). The rod elements are industrially achievable from the cold shaping of thin sheets, while most of the connecting elements are made up of straight or bent and perforated sheets (fig. 7-8-9-10), which can also be made in this case in an industrial way; the number of elements on which human intervention is necessary are the welded elements that make up the base plates and some elements for fixing the braces (fig. 11-12-13-14-15), which result in number extremely limited compared to the totality of the elements of the building.
L’industrializzazione della costruzione e la ripetitività degli elementi consente di poter stoccare a magazzino delle serie di elementi standard che possono essere assemblati all’occorrenza, con un intervento dedicato solamente su pochi elementi (che in ogni caso risultano ricavabili dal elementi standard). Tale aspetto consente di ridurre in maniera drastica i tempi della progettazione di ingegneria e i tempi di realizzazione dei disegni esecutivi, oltre che ridurre i tempi di prefabbricazione, in quanto avendo la maggior parte degli elementi stoccati a magazzino, la costruzione viene limitata a un numero estremamente esiguo di elementi. Tale aspetto, se collegato ai tempi di realizzazione delle opere di finitura, consente di avere fabbricati finiti in tempi che possono essere stimati in non più di 4 mesi, e pertanto rendono il sistema molto vantaggioso nel caso di fabbricati da realizzare in condizione di emergenza (a seguito di sismi, alluvioni, ecc...). The industrialization of the construction and the repetitiveness of the elements makes it possible to store series of standard elements in the warehouse that can be assembled if necessary, with a dedicated intervention only on a few elements (which in any case can be obtained from the standard elements). This aspect makes it possible to drastically reduce the engineering design time and the execution time of the executive drawings, as well as reduce prefabrication times, as having most of the elements stored in stock, construction is limited to an extremely large number. few elements. This aspect, if connected to the completion times of the finishing works, allows to have finished buildings in times that can be estimated in no more than 4 months, and therefore make the system very advantageous in the case of buildings to be built in emergency conditions ( following earthquakes, floods, etc ...).
La realizzazione degli elementi standard non richiede particolari macchinari, risultando di facile reperibilità sul mercato, in quanto utilizzati per altre tipologie di impiego. Pertanto possono essere realizzati da aziende locali vicine ai siti d costruzione, qualora tale scelta possa risultare vantaggiosa. Inoltre tale aspetto consente la garanzia di un rapido sviluppo della tecnologia in esame, essendo sfruttabili aziende esistenti che producono elementi simili per utilizzi diversi. La modularità degli elementi consente di ottenere diverse tipologie costruttive (case singole, bifamiliari, palazzine) anche con più piani, con forme varie, con i solo vincolo di rispettare alcuni limiti legati alla modularità, ma che consentono comunque di garantire molteplici gradi di libertà al progettista architettonico (come visibile su un esempio riportato in fig.20). The realization of the standard elements does not require special machinery, making it easy to find on the market, as they are used for other types of use. Therefore they can be made by local companies close to the construction sites, if this choice can be advantageous. Furthermore, this aspect allows the guarantee of a rapid development of the technology in question, since existing companies that produce similar elements for different uses can be exploited. The modularity of the elements allows to obtain different construction types (single houses, semi-detached houses, buildings) even with several floors, with various shapes, with the only constraint of respecting some limits linked to modularity, but which still allow to guarantee multiple degrees of freedom to the architectural designer (as shown on an example shown in fig. 20).
Con l’assemblaggio di tali elementi risulta possibile realizzare l’ossatura principale della struttura portante di fabbricati sui quali sarà possibile applicare successivamente i rivestimenti. With the assembly of these elements it is possible to create the main framework of the supporting structure of buildings on which it will be possible to subsequently apply the coatings.
L’utilizzo di elementi con sezione a C sagomati a freddo consente di avere spessori ridotti (max = 4 mm) sui quali risulta possibile fissare i rivestimenti con viti autofilettanti senza necessità di prevedere punti di aggancio dei tamponamenti. Tale aspetto svincola la struttura principale dalle opere di finitura che potranno essere realizzate secondo le varie esigenze, senza necessità di predisporre fissaggi su misura a seconda del rivestimento scelto. The use of cold-shaped C-section elements allows for reduced thicknesses (max = 4 mm) on which it is possible to fix the coverings with self-tapping screws without the need to provide attachment points for the infill panels. This aspect frees the main structure from the finishing works that can be carried out according to the various needs, without the need to prepare customized fixings according to the chosen coating.
Tutti gli elementi metallici presentano un peso estremamente ridotto (dell’ordine dei 60-80 kg massimi per gli elementi di lunghezza maggiore realizzati con profili di spessore 4 mm, ma generalmente con peso di 30-40 kg per gli elementi di utilizzo più frequente) in modo da consentire un montaggio agevole anche con l’ausilio di attrezzature di sollevamento limitate e/o in assenza di attrezzature di sollevamento. All the metal elements have an extremely low weight (of the order of 60-80 kg maximum for the elements of greater length made with 4 mm thick profiles, but generally with a weight of 30-40 kg for the elements of more frequent use) in order to allow easy assembly even with the aid of limited lifting equipment and / or in the absence of lifting equipment.
Il montaggio dei vari elementi può essere realizzato a secco con l'inserimento di lamine in acciaio di controvento di piano, limitando pertanto gli interventi “a umido” alle sole opere di fondazione in calcestruzzo. In alternativa è possibile realizzare i solai di piano con delle solette in c.a. realizzate su lamiera grecata collaborante, che consentono di ottenere un piano rigido, anche se con un apporto in termini di peso non trascurabile. The assembly of the various elements can be carried out dry with the insertion of steel plates to brace the floor, thus limiting the "wet" interventions to the concrete foundation works only. Alternatively, it is possible to create floor slabs with reinforced concrete slabs. realized on collaborating corrugated sheet, which allow to obtain a rigid surface, even if with a contribution in terms of not negligible weight.
I fabbricati con struttura in acciaio tradizionali necessitano della realizzazione di disegni esecutivi di officina, con l'indicazione di lunghezze di taglio, forature, ecc... con quotature eseguite con precisione millimetrica; con la soluzione oggetto del brevetto tutti gli elementi, compresi la maggior parte dei nodi, risultano standard e pertanto possono essere pezzi “disponibili a magazzino”. Per gli elementi che necessitano di uno studio tuttavia risulta possibile effettuarlo seguendo schemi standard senza necessità del disegno esecutivo dell’intero fabbricato (per esempio i nodi trave-colonna-controvento riportati in fìg .11 che a seconda della presenza o meno dei controventi e della inclinazione, necessitano di essere definiti su misura, anche se secondo schemi standard, e pertanto senza necessità di disegno della struttura). La definizione della struttura può pertanto essere eseguita su una sorta di “carta quadrettata” secondo i moduli degli elementi (fig. 16-17-18), sulla quale è possibile individuare gli elementi costituenti la struttura solamente contando i moduli (e ovviamente individuando la serie corretta a cui si fa riferimento, nelle fig. 16-17-18 presentano colori differenti). Buildings with traditional steel structures require the realization of executive drawings of the workshop, with the indication of cutting lengths, holes, etc ... with dimensions carried out with millimeter precision; with the solution covered by the patent all the elements, including most of the nodes, are standard and therefore can be pieces "available in stock". For the elements that require a study, however, it is possible to carry out it following standard schemes without the need for the executive design of the entire building (for example the beam-column-bracing nodes shown in fig. inclination, they need to be tailor-made, even if according to standard schemes, and therefore without the need for a design of the structure). The definition of the structure can therefore be performed on a sort of "squared paper" according to the modules of the elements (fig. 16-17-18), on which it is possible to identify the elements making up the structure only by counting the modules (and obviously identifying the correct series to which reference is made, in figs. 16-17-18 have different colors).
Nella realizzazione di edifici con gli elementi modulari in esame inoltre non si impedisce che possano essere inseriti altri elementi complementari a quelli oggetto del brevetto, come ad esempio un tetto in legno o un tetto in acciaio con padiglioni o abbaini, o similari (elementi non modulari studiati su misura), al fine di realizzare parti del fabbricato con caratteristiche architettoniche di vario tipo o in ogni caso diverse da quelle realizzabili solamente con gli elementi standard. Furthermore, in the construction of buildings with the modular elements in question, it is not prevented that other elements complementary to those covered by the patent can be inserted, such as a wooden roof or a steel roof with pavilions or dormers, or similar (non-modular elements designed to measure), in order to create parts of the building with architectural characteristics of various types or in any case different from those that can only be achieved with standard elements.
Grazie alle masse ridotte dei fabbricati realizzati secondo la tecnologia illustrata, risulta estremamente facile realizzare fabbricati con elevate prestazioni rispetto alle azioni sismiche, e anche in zone ad altissima sismicità non c’è nessun incremento dei costi di costruzione. Thanks to the small masses of the buildings built according to the illustrated technology, it is extremely easy to build buildings with high performance compared to seismic actions, and even in areas with very high seismicity there is no increase in construction costs.
La bassa massa del fabbricato risulta inoltre vantaggiosa in quanto consente di scaricare carichi estremamente ridotti sulle opere di fondazione, riducendo in maniera significativa i costi di queste ultime, e scaricando pesi sul terreno talmente bassi che consentono di escludere cedimenti fondazionali anche in presenza di terreni con caratteristiche estremamente scadenti. The low mass of the building is also advantageous as it allows extremely low loads to be unloaded on the foundation works, significantly reducing the costs of the latter, and unloading weights on the ground so low that they allow to exclude foundational subsidence even in the presence of soils with extremely poor features.
La tipologia rappresentata nei disegni viene realizzata con profili a C con aletta di dimensione 150x70x30 (spessore variabile) che se accoppiati tra loro con una piastra da 10 mm consentono di ottenere un ingombro di 150 mm x 150 mm sia su travi che su pilastri (fig.2), consentendo di avere degli elementi sui cui ancorare i rivestimenti che giacciono tutti sullo stesso piano. Tale tipologia è stata studiata in modo da consentire di avere maglie strutturali di dimensione 567 cm x 567 cm, che risultano idonee alla costruzione della maggior parte di fabbricati civili; ovviamente il sistema risulta ampliabile con l'utilizzo di elementi di sezione maggiore, al fine di raggiungere maglie strutturali di dimensione maggiore, e tutte le considerazioni valide nei disegni allegati relativi al caso degli elementi a C da 150x70x30 vengono estese a tutte le tipologie simili realizzate con profili maggiori o minori. The typology represented in the drawings is made with C-shaped profiles with fin size 150x70x30 (variable thickness) which when coupled together with a 10 mm plate allow to obtain a footprint of 150 mm x 150 mm both on beams and on pillars (fig. .2), allowing to have elements on which to anchor the coverings that all lie on the same plane. This typology has been designed in such a way as to allow for structural meshes with dimensions of 567 cm x 567 cm, which are suitable for the construction of most civil buildings; obviously the system can be expanded with the use of elements of greater section, in order to reach structural meshes of greater size, and all the considerations valid in the attached drawings relating to the case of the C-shaped elements from 150x70x30 are extended to all similar types made with major or minor profiles.
