Descrizione Description

La presente invenzione ha per oggetto un sistema molleggiente direzionale particolarmente utile per costruire murature di tamponamento in zone ad alto rischio sismico. Come è noto, nel settore edilizio la protezione antisismica riguarda solo le strutture portanti e non le murature di tamponamento. The present invention relates to a directional springing system particularly useful for building infill walls in areas with high seismic risk. As is known, in the building sector the anti-seismic protection concerns only the load-bearing structures and not the infill walls.

In generale, le strutture degli edifìci costituiscono un insieme tridimensionale nel quale l'elevata rigidezza planare degli impalcati impone un asservimento agli spostamenti orizzontali di ogni livello cosi che i modi fondamentali di vibrazione sono riconducibili a combinazioni di traslazioni orizzontali lungo due assi ortogonali e di una rotazione attorno ad un asse verticale; fra due piani successivi intervengono negli elementi verticali le deformazioni dovute alla flessione ed al taglio. In general, the structures of the buildings constitute a three-dimensional whole in which the high planar stiffness of the decks imposes an enslavement to the horizontal displacements of each level so that the fundamental modes of vibration are attributable to combinations of horizontal translations along two orthogonal axes and one rotation around a vertical axis; between two successive floors the deformations due to bending and shear intervene in the vertical elements.

Durante questo processo, le strutture di tamponamento subisco delle forti pressioni orizzontali dovute alle spinte della traslazio delle strutture armate verticali. Poiché le strutture di tamponamento non sono rigide e neppure armate, non resistono alle oscillazioni sismiche. During this process, the infill structures are subjected to strong horizontal pressures due to the thrusts of the translation of the vertical reinforced structures. Since the infill structures are neither rigid nor reinforced, they are not resistant to seismic oscillations.

Lo scopo della presente invenzione è di rendere rigide le strutture di tamponamento, libere da impalcati e pilastri, nello stesso tempo renderle fortemente ancorate ad essi, ma con la possibilità, tramite i giunti sismici e i dissipatori, di dissipare tutta l'energia sismica, anche quella massima. The purpose of the present invention is to make the infill structures rigid, free from decks and pillars, at the same time making them strongly anchored to them, but with the possibility, through the seismic joints and the dissipators, to dissipate all the seismic energy, even the maximum one.

Infatti, analizzando la storia degli eventi sismici succedutisi in Italia dal 1169 ad oggi, ad essere soggetti al crollo totale sono stati i muri degli edifici, non le strutture portanti. Riguardo al sisma che ha colpito recentemente l'Abruzzo, si è visto che le strutture portanti ben costruite hanno resistito in qualche modo alla forte spinta tellurica, mentre le mura sono crollate. Molte costruzioni presentavano i muri perimetrali completamente sfondati come da cannonate. Ciò vuol dire che non solo le strutture portanti devono essere costruite con criterio antisismico, ma anche le murature di tamponamento e i muri divisori. In fact, analyzing the history of the seismic events that took place in Italy from 1169 to today, the walls of the buildings, not the load-bearing structures, were subject to total collapse. With regard to the earthquake that recently hit Abruzzo, it has been seen that the well-built supporting structures somehow resisted the strong earthquake, while the walls collapsed. Many buildings had the perimeter walls completely broken down as if by cannon fire. This means that not only the load-bearing structures must be built with anti-seismic criteria, but also the infill walls and dividing walls.

Lo scopo della presente invenzione è proprio quello di garantire la massima sicurezza e incolumità a persone e cose, prestando attenzione alle mura dell'intera costruzione, e privilegiando l'utilizzo di materiali aventi bassa densità, in modo da ottenere resistenza e leggerezza del manufatto che, anche in caso estremo di sgretolamento della struttura, non costituirebbe mai un pericolo per la vita delle persone. The purpose of the present invention is precisely that of guaranteeing maximum safety and safety to people and things, paying attention to the walls of the entire building, and favoring the use of low density materials, in order to obtain strength and lightness of the product which , even in the extreme case of crumbling of the structure, it would never constitute a danger to people's lives.

Tale scopo di elevata sicurezza si raggiunge anche con la particolare struttura del manufatto che consente di dissipare la spinta telluri non all'interno della muratura ma nelle balestre di acciaio che la supportano. This purpose of high safety is also achieved with the particular structure of the product which allows to dissipate the tellur thrust not inside the masonry but in the steel leaf springs that support it.

Altro scopo della presente invenzione è quello di realizzare costruzioni antisimiche che presentino contemporaneamente eccellenti proprietà di isolamento termico e acustico senza che questo incida in modo sensibile sui costi di realizzazione . Another object of the present invention is that of realizing antisimic constructions which present at the same time excellent thermal and acoustic insulation properties without this significantly affecting the construction costs.

Altro scopo della presente invenzione è quello di costruire tamponamenti antisismici di maggior pregio , con tempi di realizzazione e costi inferiori. Another object of the present invention is to construct anti-seismic infill walls of greater value, with lower manufacturing times and costs.

Tutto questo è possibile utilizzando la "Cintura Metallica Antisismica Lanza" oscillante in ogni direzione insieme a speciali blocchi termoacustici di bassa densità, murati e incollati con malta termica airinterno della cintura stessa. All this is possible using the "Lanza Antisismica Metal Belt" oscillating in every direction together with special low density thermoacoustic blocks, walled and glued with thermal mortar inside the belt itself.

I blocchi protetti da tiranti metallici sia in orizzontale che in verticale sono connessi tramite bulloni alle nove balestre. The blocks protected by metal tie rods both horizontally and vertically are connected by bolts to the nine leaf springs.

In tal modo, blocchi e cintura costituiscono un corpo inscindibile che in caso di sisma segue il movimento elastico dei pilastri, senza possibilità di frantumarsi. In this way, the blocks and the belt form an inseparable body which in the event of an earthquake follows the elastic movement of the pillars, without the possibility of shattering.

Ulteriori caratteristiche e vantaggi della "Cintura Metallica Lanza", risulteranno più chiaramente dal progetto illustrato nelle tavole allegate, riferito ad una sua possibile forma realizzativa, che costituisce solo un esempio tra molte alternative possibili. Further characteristics and advantages of the "Lanza Metal Belt" will become clearer from the project illustrated in the attached tables, referring to one of its possible embodiments, which constitutes only one example among many possible alternatives.

La figura 1 mostra la sezione di un lato della cintura con due di scorrimento: una inferiore e una superiore: su ognuna di agganciato un dissipatore supportato da una balestra. Figure 1 shows the section of one side of the belt with two sliding elements: one lower and one upper: on each one a dissipator supported by a crossbow is attached.

La figura 2 mostra la sezione della balestra aperta: alle estremità si notano i punti di fissaggio dei dissipatori , al centro il punto di fissaggio ai pilastri. Figure 2 shows the cross-section of the open crossbow: at the ends you can see the fixing points of the heat sinks, in the center the fixing point to the pillars.

La figura 3 mostra la balestra chiusa con le estremità fissate ai dissipatori. Figure 3 shows the closed crossbow with the ends fixed to the heat sinks.

La figura 4 mostra il punto di connessione centrale balestra/pilastro. La figura 5 mostra uno spezzato di tamponamento ultimato alfinterno della cintura ancorata su quattro lati alle balestre, con bulloni che passano dalla faccia opposta del pilastro agganciando l'altro tamponamento. Si vede inoltre che in corrispondenza di ogni balestra , nel punto dove forzano i dissipatori, ci sono dei tiranti (due per ogni balestra) in orizzontale e in verticale. Figure 4 shows the central crossbow / pillar connection point. Figure 5 shows a section of the infill completed inside the belt anchored on four sides to the leaf springs, with bolts passing from the opposite face of the pillar hooking the other infill. It is also seen that in correspondence of each crossbow, in the point where the dissipators are forced, there are tie rods (two for each crossbow) horizontally and vertically.

La figura 6 mostra il tamponamento completo di tiranti, racchiuso nella cintura, ancorato a tutte le balestre fra i due solai e i due pilastri. Figure 6 shows the infill complete with tie rods, enclosed in the belt, anchored to all the leaf springs between the two floors and the two pillars.

Si vedono inoltre i punti molleggianti su cui poggia la struttura: tre sul solaio inferiore, due sul solaio superiore, due per ogni lato, quattro in verticale; in totale 13 punti di oscillazione dovuta alle balestre che hanno come caratteristica principale l'elasticità. You can also see the spring points on which the structure rests: three on the lower floor, two on the upper floor, two on each side, four vertically; a total of 13 points of oscillation due to the crossbows which have elasticity as their main feature.

La figura 7 mostra un frammento di cintura con la fascia di scorrimento "asolata" in senso orizzontale , su cui è ancorata al centro la balestra. La struttura con foro a forma di asola favorisce appunto il movimento ondulatorio. Figure 7 shows a fragment of a belt with the sliding band "slotted" horizontally, on which the crossbow is anchored in the center. The structure with a slot-shaped hole favors the wave movement.

La figura 8 mostra la balestra non sagomata il cui centro essere fissato al pilastro; le estremità asolate in senso servono a favorire lo scorrimento della struttura in caso di moto sussultorio. Figure 8 shows the non-shaped crossbow whose center be fixed to the pillar; the ends slotted in the direction are used to facilitate the sliding of the structure in the event of a jolting motion.

La figura 9 mostra la balestra montata al contrario nel caso in fase di edificazione in un contesto particolare, i tecnici ritenessero opportuno quel tipo di assemblaggio. Figure 9 shows the crossbow mounted upside down in the case during the construction phase in a particular context, the technicians deemed appropriate that type of assembly.

La connessione balestre / supporti e tiranti/cintura, avviene tramite bulloni di adeguate dimensioni , ma in alterativa possono essere adoperati mezzi di connessione equivalenti, come pure l'ancoraggio del sistema di molleggiamento può essere eseguito al contrario , così come evidenziato dalle figure 7, 8 e 9. The connection of leaf springs / supports and tie rods / belt, takes place through bolts of adequate size, but as an alternative equivalent connection means can be used, as well as the anchoring of the springing system can be performed in reverse, as shown in figure 7, 8 and 9.

Le costruzioni realizzate con il sistema "Cintura metallica Antisismica Lanza" secondo quanto esposto nella presente invenzione, e con I' impiego dei particolari materiali per le murature di tamponamento, presentano oltre alle caratteristiche antisismiche descritte, elevate proprietà termiche ed acustiche come : permeabilità al vapore (μ) = 5,3; trasmittanza termica U=0,16; Abbattimento acustico Rw = 60 dB. The constructions made with the "Lanza Antisismic Metal Belt" system according to what is set out in the present invention, and with the use of particular materials for the infill walls, present in addition to the anti-seismic characteristics described, high thermal and acoustic properties such as: vapor permeability (μ) = 5.3; thermal transmittance U = 0.16; Noise reduction Rw = 60 dB.

Le unità abitative così costruite sono a basso fabbisogno energetico, avendo un consumo energetico annuo inferiore a 10 kW*h per metro quadrato , pari a circa un litro di gasolio per metro quadro annuo; rientrano quindi, secondo le recenti normative sull' obbligo di edificare con criteri di risparmio energetico, nella categoria degli edifici di classe "A Oro". The housing units built in this way have low energy requirements, having an annual energy consumption of less than 10 kW * h per square meter, equal to about one liter of diesel per square meter per year; therefore, according to the recent regulations on the obligation to build with energy saving criteria, they fall within the category of class "A Gold" buildings.
