Description

“Un sistema semiprefabbricato per la realizzazione di pareti composti in acciaio-calcestruzzo” "A semi-prefabricated system for the construction of composite steel-concrete walls"

DESCRIZIONE DESCRIPTION

La presente invenzione si riferisce ad una tecnologia che consente di realizzare pareti e pilastri composti acciaio-calcestruzzo, in modo rapido ed efficiente. The present invention relates to a technology that allows the construction of composite steel-concrete walls and pillars, quickly and efficiently.

Con la tecnologia in esame, è possibile realizzare pareti e pilastri in c.a., in modo molto più rapido, rispetto ad un elemento tradizionale in calcestruzzo armato, in quanto la “gabbia” d’acciaio costituente l’armatura dell’elemento, può essere montata per due-tre interpiani e non per un unico interpiano, come si fa tradizionalmente, grazie ad una struttura metallica interna alla “gabbia”, che in fase di montaggio serve a sostenere la “gabbia” stessa, e dopo il getto risulta perfettamente collaborante con il calcestruzzo, facendo parte della struttura resistente. With the technology in question, it is possible to create walls and pillars in reinforced concrete, in a much faster way, compared to a traditional element in reinforced concrete, as the steel "cage" constituting the reinforcement of the element can be mounted for two-three storeys and not for a single storey, as is traditionally done, thanks to a metal structure inside the "cage", which in the assembly phase serves to support the "cage" itself, and after casting it works perfectly with the concrete, being part of the resistant structure.

Il sistema presentato, consente altri vantaggi, rispetto alle strutture tradizionali in c.a., oltra a quella già evidenziata, e di non poco conto, che è legata alla rapidità di esecuzione. In particolare, gli elementi strutturali che ne risultano, presentano dimensioni minori rispetto agli analoghi in c.a., ovvero a parità di dimensioni, sono più rigidi e resistenti; ed ancora la quantità di armatura in acciaio presente “Un sistema semiprefabbricato per la realizzazione di pareti composti in acciaio-calcestruzzo” The presented system allows other advantages, compared to traditional structures in reinforced concrete, in addition to the one already highlighted, and of no small importance, which is linked to the speed of execution. In particular, the resulting structural elements have smaller dimensions than the analogues in reinforced concrete, or with the same dimensions, they are more rigid and resistant; and the quantity of steel reinforcement present "A semi-prefabricated system for the construction of composite walls in steel-concrete"

negli elementi è assai inferiore, mancando tutte le zone di sovrapposizione” che notoriamente possono rappresentare il 15-20% dell’armatura complessiva di un elemento strutturale in c.a. in the elements it is much lower, missing all the overlapping areas "which notoriously can represent 15-20% of the overall reinforcement of a structural element in reinforced concrete.

Rispetto ad una struttura in acciaio, presentano tutti i vantaggi specifici delle strutture in c.a., non ultimo quello della ottima resistenza al fuoco. Compared to a steel structure, they have all the specific advantages of reinforced concrete structures, not least that of excellent fire resistance.

Con riferimento alla sezione tipica, riportata nella tavola A, possono individuarsi gli elementi fondamentali della parete composta acciaio-calcestruzzo, di nuova concezione. With reference to the typical section, shown in table A, the fundamental elements of the newly designed composite steel-concrete wall can be identified.

Gli elementi 1, 4 e 11, rappresentano la “gabbia” di armatura in acciaio presente all’interno del calcestruzzo, mentre gli elementi 2, sono i profili verticali in carpenteria metallica, posti all’estremità della parete. Elements 1, 4 and 11 represent the steel reinforcement "cage" present within the concrete, while elements 2 are the vertical profiles in metal carpentry, placed at the end of the wall.

I profili verticali, e la gabbia metallica, risultano collegati direttamente per saldatura sui profili, delle staffe orizzontali della gabbia (elementi 4); i medesimi profili sono collegati al calcestruzzo circostante attraverso un sistema di nuova concezione, realizzato con barre diagonali in acciaio (elementi 3) che sono ad una estremità ancorate alla gabbia di armatura (elementi 1 e 6), mentre all’altra sono “Un sistema semiprefabbricato per la realizzazione di pareti composti in acciaio-calcestruzzo” The vertical profiles and the metal cage are directly connected by welding on the profiles of the horizontal brackets of the cage (elements 4); the same profiles are connected to the surrounding concrete through a new concept system, made with diagonal steel bars (elements 3) which are anchored at one end to the reinforcement cage (elements 1 and 6), while at the other they are "A system semi-prefabricated for the construction of composite walls in steel-concrete "

forzate contro i profili verticali in carpenteria metallica, dall’elemento di connessione vero e proprio (elemento 5). forced against the vertical profiles in metal carpentry, by the actual connection element (element 5).

Tale elemento, viene riportato nella tavola E ed è costituito da un cilindro pieno in acciaio (elemento 7) che risulta parzialmente filettato internamente, in modo da accogliere una barra in acciaio interamente filettata (elemento 8). La barra, viene disposta ad attraversare l’anima del profilo in acciaio, e tramite un dado di registro (elemento 9), consente di serrare le barre diagonali (elemento 3) fra il cilindro (elemento 7) e l’anima del profilo. This element is shown in table E and consists of a solid steel cylinder (element 7) which is partially internally threaded, so as to accommodate a fully threaded steel bar (element 8). The bar is arranged to cross the core of the steel profile, and through a adjusting nut (element 9), allows you to tighten the diagonal bars (element 3) between the cylinder (element 7) and the core of the profile.

La stessa barra filettata, presenta all’altra estremità, un altro dado (elemento 10) per il suo efficace ancoraggio al calcestruzzo. The same threaded bar has another nut (element 10) at the other end for its effective anchoring to the concrete.

Nella tavola B, è rappresentato il prospetto di una possibile parete, realizzata con la tecnologia presentata. Nella figura di destra, il prospetto completo dell’elemento costituito dalla struttura in carpenteria metallica interna, e dalla gabbia di armatura; in quella di sinistra la struttura in carpenteria metallica interna. In entrambe le figure, si nota una parte inferiore, ed una parte superiore distaccata dall’altra con due frecce adiacenti rivolte verso il basso. Le parti inferiori rappresentano la prima parte degli elementi, collegata in fondazione, e le “Un sistema semiprefabbricato per la realizzazione di pareti composti in acciaio-calcestruzzo” Table B shows the elevation of a possible wall, made with the technology presented. In the figure on the right, the complete elevation of the element consisting of the internal metal carpentry structure, and the reinforcement cage; in the left one, the internal metal carpentry structure. In both figures, there is a lower part, and an upper part detached from the other with two adjacent arrows pointing downwards. The lower parts represent the first part of the elements, connected in the foundation, and the "A semi-prefabricated system for the construction of composite walls in steel-concrete"

frecce simboleggiano una possibile parte superiore che può essere giuntata a quelle sottostanti. La struttura interna, è costituita dai profili di estremità (elementi 2), dal loro collegamento di base (elementi 16), dall’eventuale giunto superiore (elementi 18), da alcuni elementi di controvento (elementi 13) con il loro ancoraggio di estremità (elementi 14), da traversi di collegamento (elementi 12). Nella medesima figura, gli elementi orizzontali tratteggiati rappresentano le travi di piano della struttura, in acciaio o calcestruzzo armato, che possono collegarsi alle pareti in questione (elementi 15). arrows symbolize a possible upper part that can be joined to those below. The internal structure consists of the end profiles (elements 2), their base connection (elements 16), any upper joint (elements 18), some bracing elements (elements 13) with their end anchoring (elements 14), by connecting crosspieces (elements 12). In the same figure, the dashed horizontal elements represent the floor beams of the structure, in steel or reinforced concrete, which can be connected to the walls in question (elements 15).

Nella tavola C, è riportato il giunto di base della parete composta con rappresentati i ferri di ripresa provenienti dalla fondazione (elementi 17). Table C shows the base joint of the composite wall with the reinforcement bars coming from the foundation (elements 17) represented.

Nella tavola D, sono riportati i traversi orizzontali costituiti da piastre verticali (elementi 12) collegati da profili con sezione a “C” (elementi 20); sopra ai traversi sono saldati gli elementi di supporto delle barre di armatura del calcestruzzo (elementi 19), sono inoltre evidenziati gli elementi di controvento costituiti da diagonali in acciaio (elemento 13) fissati all’anima dei profili metallici di estremità, da profili angolari (elementi 14). Table D shows the horizontal crosspieces consisting of vertical plates (elements 12) connected by profiles with a “C” section (elements 20); the supporting elements of the concrete reinforcement bars are welded above the crosspieces (elements 19), the bracing elements consisting of steel diagonals (element 13) fixed to the core of the metal end profiles, by angular profiles ( items 14).

“Un sistema semiprefabbricato per la realizzazione di pareti composti in acciaio-calcestruzzo” "A semi-prefabricated system for the construction of composite steel-concrete walls"

Nella tavola E in basso è riportato il possibile giunto tra moduli successivi in altezza (elemento 18), nonché nella figura superiore il prospetto laterale e la vista in planimetria, del collegamento fra i profili di estremità (elementi 2) ed il calcestruzzo circostante, come già esplicitato in precedenza. Table E below shows the possible joint between successive modules in height (element 18), as well as in the upper figure the side elevation and the plan view, of the connection between the end profiles (elements 2) and the surrounding concrete, as already explained above.

Nella tavola F, è riportato un impiego importante delle pareti, realizzate con la tecnologia indicata, per la costruzione di vani scala-ascensore di qualsiasi dimensione. Si tratta in sostanza degli stessi elementi, ma con la presenza di alcune forature. Per vani alti e stretti, elemento (21), la parete può essere di tipo pluripiano come già mostrato prima, per elementi larghi invece, esigenze di montaggio consigliano come più appropriato il montaggio di un unico elemento (elemento 22). Table F shows an important use of the walls, made with the indicated technology, for the construction of stair-lift shafts of any size. These are essentially the same elements, but with the presence of some punctures. For tall and narrow compartments, element (21), the wall can be of the multi-storey type as already shown above, for large elements on the other hand, assembly requirements recommend as more appropriate the assembly of a single element (element 22).

Le pareti, vengono montate, accostate fra loro, vengono solidarizzate lungo gli spigoli comuni attraverso gli elementi 25, e poi vengono completate con le armature verticali di spigolo (elemento 23), inserite nelle armature orizzontali che proseguono all’interno del nodo (elementi 24) e successivamente con i getti di calcestruzzo. The walls are assembled, juxtaposed together, are joined together along the common edges through the elements 25, and then are completed with the vertical corner reinforcements (element 23), inserted in the horizontal reinforcements that continue inside the node (elements 24 ) and then with concrete castings.

“Un sistema semiprefabbricato per la realizzazione di pareti composti in acciaio-calcestruzzo” "A semi-prefabricated system for the construction of composite steel-concrete walls"

Nella tavola G si riporta un’altra caratteristica importante del sistema che si presenta, ovvero la possibilità di inserire tubazioni in acciaio all’interno della parete (elemento 26), per il passaggio di impiantistica o scarichi, che grazie al particolare sistema di ancoraggio (elemento 27) non costituiscono un<indebolimento dell’elemento strutturale.>Table G shows another important feature of the system presented, namely the possibility of inserting steel pipes inside the wall (element 26), for the passage of systems or drains, which thanks to the particular anchoring system ( element 27) do not constitute a <weakening of the structural element.>

Nella tavola H, si presenta inoltre una possibilità che può rendere il sistema, ulteriormente efficiente, per la tempistica di realizzazione della costruzione in cui si trova ad essere inserito, ovvero la possibilità di montare gli elementi, già con i casseri, in modo da accelerare il processo costruttivo, e non dover fare altro, per completare l’elemento strutturale, se non il riempimento con calcestruzzo. In table H, there is also a possibility that can make the system, further efficient, for the timing of construction of the construction in which it is to be inserted, that is the possibility of assembling the elements, already with the formworks, in order to accelerate the construction process, and not having to do anything else, to complete the structural element, other than the filling with concrete.

La parete infatti, può essere associata a delle casserature di qualsiasi tipo (elementi 29), sostenute alla base da una struttura in angolari d’acciaio (elementi 30) fissata da barre filettate, ancorate da particolari armature verticali inclinate (elemento 31), e lungo lo sviluppo in altezza, da barre filettate di diametro opportuno (elemento 28). In fact, the wall can be associated with formworks of any type (elements 29), supported at the base by a steel corner structure (elements 30) fixed by threaded bars, anchored by particular inclined vertical reinforcements (element 31), and along the development in height, by threaded bars of suitable diameter (element 28).
