Descrizione dell’invenzione industriale dal titolo: Description of the industrial invention entitled:
CONNETTORE METALLICO PER LA CONNESSIONE DI ELEMENTI IN LEGNO AL CONGLOMERATO CEMENTIZIO AGGIUNTO IN OPERA SUCCESSIVAMENTE ED IN PARTICOLARE PER LA COSTRUZIONE DI SOLAI PORTANTI A NERVATURE PARALLELE IN LEGNO E MASSETTO IN CONGLOMERATO CEMENTIZIO ARMATO; METALLIC CONNECTOR FOR THE CONNECTION OF WOODEN ELEMENTS TO THE CEMENTITIOUS CONGLOMERATE ADDED ON SUCCESSIVELY AND IN PARTICULAR FOR THE CONSTRUCTION OF LOADING FLOORS WITH PARALLEL RIBS IN WOOD AND SCREED IN REINFORCED CEMENTITIOUS CONGLOMERATE;
La presente invenzione riguarda la produzione ed applicazione di un connettore metallico, prevalentemente in acciaio, composto da due pezzi, per la connessione di elementi strutturali in legno al conglomerato cementizio posto in opera successivamente ed in particolare per la costruzione di solai portanti del tipo misto con nervature parallele costituite da travetti in legno idonei per impieghi strutturali e soprastante massetto integrativo collaborante in conglomerato cementizio armato con barre di acciaio per cemento armato e con rete elettrosaldata in acciaio. The present invention relates to the production and application of a metal connector, mainly in steel, consisting of two pieces, for the connection of structural elements in wood to the cement conglomerate subsequently installed and in particular for the construction of load-bearing floors of the mixed type with Parallel ribs consisting of wooden beams suitable for structural use and overlying integrative collaborating screed in concrete conglomerate reinforced with steel bars for reinforced concrete and with electro-welded steel mesh.
Qui di seguito, per praticità espositiva, ma anche perché trattasi del tipo di realizzazione più abituale, viene fatto riferimento solo ai solai misti sopra indicati, adottando in via esemplificativa la terminologia di "'solaio (o solai) in legno-cemento”: beninteso, senza negare alcuna possibilità applicativa del connettore per la realizzazione di altre parti strutturali, quali ad esempio "travi in legno-cemento”, ""pareti in legno-cemento”, “ pilastri in legno-cemento”, "arcate in legno-cemento” e via dicendo. Below, for practicality of display, but also because it is the most usual type of construction, reference is made only to the mixed floors indicated above, adopting as an example the terminology of "'floor (or floors) in wood-concrete": of course , without denying any possible application of the connector for the construction of other structural parts, such as "wood-concrete beams", "" wood-concrete walls "," wood-concrete pillars "," wood-concrete arches " and so on.
Esemplificando, può anche dirsi che la tecnica del legno-cemento è di derivazione da quella del cemento armato. Ad esempio, per un elemento di solaio su due appoggi, in entrambi i casi al calcestruzzo è affidata la funzione di riprendere la compressione. Nel caso del sistema legno-cemento la trazione è ripresa dal legno anziché dalle barre in acciaio come è per il cemento armato e le forze di taglio dal connettore anziché dalle staffe. As an example, it can also be said that the wood-concrete technique is derived from that of reinforced concrete. For example, for a floor element on two supports, in both cases the concrete is entrusted with the function of resuming compression. In the case of the wood-concrete system the traction is taken up by the wood instead of the steel bars as it is for the reinforced concrete and the shear forces by the connector instead of the brackets.
Oggigiorno, la tecnica dei solai misti legno-cemento è abbastanza usata. Inizialmente è stata praticata per la ristrutturazione di edifici sovente pluricentenari e negli ultimi tempi è stata utilizzata anche nella costruzione di nuoviedificiabitatividigrandezzalimitata. Nowadays, the technique of mixed wood-concrete floors is quite used. Initially it was practiced for the renovation of buildings that are often centuries-old and in recent times it has also been used in the construction of new large-scale residential buildings.
Nell’ambito delle ristrutturazioni edilizie, alcune volte è prescelta la tecnica di risanamento dei solai, mentre altre volte si opera alla loro sostituzione,conmodalitàdiesecuzioneuguali osimili aquelleattuateperi nuovi edifici. La tecnica di risanamento consiste nell'accertare la conservazione e l’idoneità dei travetti del solaio “a secco” esistente, procedendopoiarisanareconresineoaltretecnichequellidegradatiolesionati e sostituendo quelli irrecuperabili. Una volta effettuata questa prima fase dell’intervento, mantenendo o rifacendo l’assito esistente, si procede ad effettuareneitravettiinlegnounaseriediforineiqualivienecolatadellamalta epossidica o anche adesivo epossidico e vengono infissi delle barrette in acciaio, ripiegatead“L”rovescia, del tipoad aderenzamigliorataimpiegato nel cemento armato. Una volta assicurata la presa delle barrette al travetto vieneposataunareteelettrosaldataevienerealizzatounsoprastantemassetto integrativocollaboranteinconglomeratocementizio. In the context of building renovations, sometimes the technique of restoring the floors is chosen, while other times they are replaced, with the same or similar methods of execution for new buildings. The rehabilitation technique consists in ascertaining the conservation and suitability of the existing "dry" floor joists, proceeding after rehabilitating with resine or other degraded-damaged techniques and replacing the irrecoverable ones. Once this first phase of the intervention has been carried out, maintaining or redoing the existing boarding, we proceed to carry out wooden travings in a wood-covered hole with epoxy mortar or even epoxy adhesive and steel bars are fixed, folded upside down, of the type with improved adhesion used in reinforced concrete. Once the grip of the bars has been ensured to the joist, an electrically welded mesh is laid and an integrated, collaborating screed above it is created in a conglomerate cement.
Questatecnica,cheèprevalentementecantieristicaeattualmenteviene praticataancheperlarealizzazionedi nuovi solai inlegno-cemento,presenta alcuni inconvenienti. Molte ditte artigianehanno difficoltà a predisporre dei connettoria"L”rovesciadiapprezzabilediametro(adesempio16millimetri)e ciòobbligaadutilizzaredeiconnettori didiametropiùpiccolopiùfacilmente piegabili,mainunnumeroassaimaggioree quindidoverpraticaremolti piùfori. Inoltreiconnettoripiegatirendonodifficoltosorealizzareunperfetto pianodellasuperficiediestradossodelmassettointegrativodelsolaioinlegnocemento. This technique, which is mainly a construction site and is currently also used for the construction of new wood-concrete floors, has some drawbacks. Many artisan firms find it difficult to prepare an appreciable reverse "L" diameter connection (for example 16 millimeters) and this requires the use of connectors with a smaller diameter and more easily foldable, but a larger number and therefore having to practice many more holes.
La forma di utilizzazione preferita secondo l'invenzione, vale a dire quella per la costruzione di “solaio legno-cemento”, viene ora descritta in dettaglio, a puro titolo esemplificativo, con riferimento al disegno allegato: la figura 1 mostra la vista dei singoli pezzi che compongono il connettore, lo “spinotto di presa” 4 e la “capsula di connessione” con più rastremazioni 6, e la vista d’assieme di un travetto forato 1, nei cui fori 2 sono inseriti gli spinotti di presa 4, incollati con adesivo epossidico 3; sull’estremità di alcuni spinotti di presa sporgenti dai travetti è illustrato il collocamento delle capsule di connessione 5 ad una o più rastremazioni; una capsula di presa è riempita parzialmente o totalmente dallo stesso adesivo 7 utilizzato per l’incollaggio degli spinotti di presa ai travetti. The preferred form of use according to the invention, namely that for the construction of a "wood-concrete floor", is now described in detail, purely by way of example, with reference to the attached drawing: Figure 1 shows the view of the individual pieces that make up the connector, the "socket pin" 4 and the "connection capsule" with several tapers 6, and the overall view of a perforated beam 1, in whose holes 2 the socket pins 4 are inserted, glued with epoxy adhesive 3; the placement of the connection capsules 5 at one or more tapers is shown on the end of some grip pins protruding from the joists; a grip capsule is partially or totally filled with the same adhesive 7 used for gluing the grip pins to the joists.
Nella forma di esecuzione illustrata nella figura il connettore è costituito da due pezzi metallici applicati sequenzialmente. Nel travetto in legno 1 viene praticata una serie di fori 2 nei quali viene colata della resina epossidica o colla speciale 3. La resina immessa in ciascun foro serve per ottenere un solido e durevole fissaggio dello “spinotto di presa” 4, costituito preferibilmente da una barra filettata in acciaio per cemento armato con i tipici risalti o da una barra in acciaio con risalti. Comunque, non si escludono altri sistemi di infissione delle barre nel legno. In the embodiment illustrated in the figure, the connector consists of two metallic pieces applied sequentially. A series of holes 2 are made in the wooden joist 1 into which epoxy resin or special glue 3 is poured. The resin introduced into each hole serves to obtain a solid and durable fastening of the "socket pin" 4, preferably consisting of a threaded steel bar for reinforced concrete with the typical projections or a steel bar with projections. However, other systems for driving the bars into the wood are not excluded.
Poi si procede a posizionare sullo spinotto 4 la “capsula di connessione” 5 e successivamente viene versato dell’altro adesivo epossidico 7 a riempimento parziale o totale del vuoto interno della capsula 5. Qualora risulti già predisposto un assito continuo sopra i travetti, è preferibile praticare un foro di diametro maggiore nello spessore dell’assito. In tal caso è preferibile adottare delle “capsule di connessione” 6 dotate di più rastremazioni, per conseguire una maggiore rigidezza della connessione ed ovviare alla debolezza strutturale trasversale alle fibre dello strato dì assito interposto tra il travetto ed il massetto in calcestruzzo. Then the "connection capsule" 5 is positioned on the pin 4 and then another epoxy adhesive 7 is poured to partially or completely fill the internal void of the capsule 5. If a continuous boarding is already prepared above the joists, it is preferable drill a hole with a larger diameter in the thickness of the board. In this case it is preferable to use "connection capsules" 6 equipped with several tapers, to achieve greater stiffness of the connection and to obviate the structural weakness transversal to the fibers of the layer of planking interposed between the joist and the concrete screed.
Si vede dalla descrizione ora esaurita con quanta praticità e rapidità è impiegabile questo tipo di connettore, per la connessione di elementi strutturali in legno al conglomerato cementizio. E’ evidente che oltre alla comodità con cui può essere usato, questo connettore è molto sicuro per quanto riguarda la funzione strutturale. It can be seen from the description which has now been exhausted how much practicality and rapidity this type of connector can be used, for the connection of wooden structural elements to the cement conglomerate. It is evident that in addition to the convenience with which it can be used, this connector is very safe as regards the structural function.
Sono evidenti i vantaggi che le caratteristiche sopra illustrate permettono di ottenere per comodità e sicurezza di impiego per tutti coloro che adoperino il connettore secondo l’invenzione. The advantages that the features illustrated above allow to obtain for convenience and safety of use for all those who use the connector according to the invention are evident.
Si intende che le forme di realizzazione di questo connettore potranno variare entro ampi limiti per quanto riguarda il tipo e le caratteristiche del metallo impiegato, la dimensione dei pezzi e dei fori, eccetera. It is understood that the embodiments of this connector may vary within wide limits as regards the type and characteristics of the metal used, the size of the pieces and holes, etc.
Potranno inoltre cambiare la forma dell’elemento superiore denominato “capsula di connessione”, che potrà avere sezione esagonale, poligonale o qualsiasi altra, invece della sezione circolare. Come pure si intende possano cambiare anche tutte le caratteristiche di minor rilievo ed i particolari esecutivi. Comunque, si intende che tutte queste varianti rientrano pienamente nell<'>ambito della presente invenzione. They will also be able to change the shape of the upper element called "connection capsule", which may have a hexagonal, polygonal or any other section, instead of the circular section. It is also intended that all minor characteristics and executive details may also change. However, it is intended that all of these variants are fully within the scope of the present invention.
