Description

DESCRIZIONE dell’invenzione industriale avente per titolo: “Lastra piana modulare aggregabile per la formazione di strutture autoportanti a calotta sferic DESCRIPTION of the industrial invention entitled: "Modular flat slab that can be aggregated for the formation of self-supporting structures with a spherical cap

Le grandi strutture spaziali a calotta sferica sono, in genere, strutture reticolar metalliche con nodi ed aste (integrate talvolta con cavi) e richiedono nod sferici o spaziali oltre ad una esatta geometria geodetica per permettere d operare una suddivisione triangolata in parti abbastanza piccole in cui sono geometricamente visibili figure esagonali integrate da alcune pentagonali. Spesso tali strutture sono a doppio strato, formando dei veri e propri gusci, rarefatti in un reticolo triangolato, collegati tra di loro. Invece, Γ elemento modulare proposto è una lastra porzione di una corona circolare piana divisa in n parti, componibile con altre identiche attraverso cerniere cilindriche per formare le nervature strutturali di celle tridimensionali contenute nello spessore di una calotta le cui superimi esterne ed interne risultano suddivise in losanghe. The large spatial structures with a spherical cap are, in general, reticular metallic structures with nodes and rods (sometimes integrated with cables) and require spherical or spatial nodes in addition to an exact geodesic geometry to allow to operate a triangulated subdivision into fairly small parts in which hexagonal figures supplemented by some pentagonals are geometrically visible. Often these structures are double-layered, forming real shells, rarefied in a triangulated lattice, connected to each other. Instead, the proposed modular element is a plate portion of a flat circular crown divided into n parts, modular with other identical parts through cylindrical hinges to form the structural ribs of three-dimensional cells contained in the thickness of a cap whose outer and inner surfaces are divided into lozenges.

Principio teorico del ritrovato: Theoretical principle of the invention:

Con riferimento alle figure della tavola di disegno 1/1 allegata, suddividiamo radialmente la superficie di una corona circolare disposta nel piano xy in un numero n di parti uguali, ognuno di lunghezza “b”; se le riuniamo, incerierandole reciprocamente Luna all’altra secondo la suddivisione radiale operata, ricostruiremo in piano la corona circolare di partenza. Se dopo la suddivisione ne aumentiamo il loro numero inserendo, con analoghe cerniere cilindriche, ulteriori altri k parti uguali alle precedenti, ciascuno di questi n+k pezzi non potrà più formare la corona circolare piana di partenza, perché una suddivisione in n+k parti comporta una lunghezza “a” minore di “b” e quindi ciascun pezzo di lunghezza “b”, dovendo tutti gli n+k pezzi sviluppare un perimetro maggiore, non poggerà più per intero sul piano xy di partenza, ma alternativamente solo per una sua estremità radiale, mentre l’altra dovrà uscire fuori dal piano xy e, dovendo convergere verso lo stesso centro della corona piana di partenza, si disporrà adesso spazialmente secondo un andamento a zig zag contenuto nello spessore di un guscio sferico (fig. 2 tavola di disegno 1/1). Se procediamo incemierando sulla precedente una nuova corona circolare di n+k pezzi sempre di lunghezza “b” e poi un’altra ed un’altra, si va a comporre la struttura rarefatta a nervature portanti di un guscio sferico sempre più completo configurato secondo cellule tridimensionali con le pareti laterali costituite da lastre, collegate da cerniere cilindriche, disposte genericamente a formare delle losanghe tridimensionali sferiche (tavola di disegno 1/1 fig. 1 , sviluppo assonometrico e fig. 3, visione zenitale). La trasmissione degli sforzi tra le varie lastre avviene attraverso le cerniere cilindriche di collegamento, per cui, fermo restante l angolatura radiale dei lati da incemierare, gli altri due lati curvi possono ininfluentemente anche essere rettilinei e la lastra si potrà configurare geometricamente anche secondo un trapezio isoscele non più mistilineo ma con tutti i lati formati da segmenti retti. With reference to the figures of the enclosed drawing table 1/1, we radially divide the surface of a circular crown arranged in the xy plane into a number n of equal parts, each of length "b"; if we join them, waxing each other with each other according to the radial subdivision made, we will reconstruct the starting circular crown on the plane. If after the subdivision we increase their number by inserting, with similar cylindrical hinges, further other k parts equal to the previous ones, each of these n + k pieces will no longer be able to form the starting flat circular crown, because a subdivision into n + k parts involves a length "a" less than "b" and therefore each piece of length "b", since all the n + k pieces have to develop a greater perimeter, will no longer rest entirely on the starting xy plane, but alternatively only for one of its radial end, while the other must come out of the xy plane and, having to converge towards the same center of the starting plane crown, it will now be spatially arranged according to a zigzag trend contained in the thickness of a spherical shell (fig. 2 table of drawing 1/1). If we proceed by hinging on the previous one a new circular crown of n + k pieces always of length "b" and then another and another, we go to compose the rarefied structure with supporting ribs of an increasingly complete spherical shell configured according to cells three-dimensional with the side walls made up of plates, connected by cylindrical hinges, generically arranged to form three-dimensional spherical lozenges (drawing table 1/1 fig. 1, axonometric development and fig. 3, zenith view). The transmission of the stresses between the various slabs takes place through the cylindrical connection hinges, so, without prejudice to the radial angle of the sides to be hinged, the other two curved sides can also be straight and the slab can also be geometrically configured according to a trapezoid. isosceles no longer mixtilinear but with all sides formed by straight segments.

Le dimensioni della lastra modulo sono funzione del numero di suddivisioni, della luce da coprire e del materiale in cui può essere realizzata, quale uno leggerissimo (a titolo esemplificativo ma non riduttivo anche polistirolo espanso ad alta densità o affine) o materiali legnosi, o plastici schiumosi, o calcestruzzi leggeri da soli o a sistema misto, inglobando elementi strutturali a travatura reticolare di materiali metallici leggeri, mentre per strutture di grandi luci, la lastra potrebbe anche essere rarefatta in una travatura reticolare con profilati metallici. The dimensions of the module slab are a function of the number of subdivisions, of the light to be covered and of the material in which it can be made, such as a very light one (by way of example but not limited to high density expanded polystyrene or similar) or wooden or plastic materials foamy, or light concretes alone or in a mixed system, incorporating truss structural elements of light metal materials, while for structures with large spans, the slab could also be rarefied into a truss with metal profiles.

Una qualsiasi sovrastruttura per una copertura di chiusura con elementi ad hoc di qualsivoglia forma e materiale opportuno, ovvero con teli, teloni, reti, di qualsivoglia materiale diafano od opaco, da soli o integrati con qualsivoglia conglomerato leggero, renderà lo spazio sottostante al coperto ed abitativo, realizzando un primo sicuro immediato temporaneo ricovero (in caso di calamità naturali) ad un numero molto alto di persone. Dopo l’uso temporaneo, quella struttura autoportante può essere liberata dalla sovrastruttura, smontata e riutilizzata in altro luogo per altre necessità temporanee ovvero definitive (in quanto già in partenza lo spazio abitativo può essere definitivo) chiudendo in maniera permanente gli spazi a losanga tra le lastre con qualsivoglia elemento di chiusura (a pannelli o a solaio) realizzato in qualsivoglia conglomerato leggero. Any superstructure for a closing covering with ad hoc elements of any suitable shape and material, or with sheets, tarpaulins, nets, of any diaphanous or opaque material, alone or integrated with any light conglomerate, will make the space below covered and housing, realizing a first secure immediate temporary shelter (in case of natural disasters) to a very high number of people. After temporary use, that self-supporting structure can be freed from the superstructure, disassembled and reused elsewhere for other temporary or definitive needs (as the living space can already be definitive from the outset) by permanently closing the lozenge-shaped spaces between the sheets with any closing element (panels or attic) made of any light conglomerate.

Tale chiusura può essere pensata come sovrastruttura permanente poggiata sul perimetro delle losanghe stesse ovvero può essere una autonoma struttura portante a guscio (con il perimetro delle losanghe a fare da appoggio all’esecuzione del sovrastante guscio) ovvero può aversi anche una soluzione strutturale di un guscio nervato con le lastre che formano le losanghe quali nervature collaboranti col guscio sovrastante. This closure can be thought of as a permanent superstructure resting on the perimeter of the lozenges themselves or it can be an autonomous supporting shell structure (with the perimeter of the lozenges supporting the execution of the overlying shell) or there can also be a structural solution of a shell ribbed with the plates that form the lozenges as ribs collaborating with the overlying shell.

Senza escludere l’idea di un doppio guscio con le lastre a formare delle nervature di collegamento strutturale. Without excluding the idea of a double shell with the slabs to form structural connection ribs.

La cerniera cilindrica, in materiale congruente con quello delle lastre e con i calcoli statici, potrà essere (come schematizzato in fig. 4) a quattro vie od anche a più (sei o otto) per rinserimento di altre lastre intermedie di irrigidimento o di appoggio intermedio agli elementi di chiusura o a formare ad un certo livello un anello troncoconico di chiusura strutturale prevedendo anche la possibilità del passaggio di cavi come tiranti di cerchiatura. The cylindrical hinge, made of material congruent with that of the slabs and with the static calculations, can be (as schematized in fig. 4) four-way or even several (six or eight) for re-insertion of other intermediate stiffening or support slabs intermediate to the closure elements or to form at a certain level a truncated cone ring for structural closure also providing the possibility of the passage of cables as tie rods.

Il tutto a titolo esemplificativo e non limitativo. All by way of non-limiting example.

Si ribadisce che il ritrovato può essere realizzato in qualsivoglia materiale e quindi può essere utilizzato in infiniti modi. It is reiterated that the invention can be made in any material and therefore can be used in infinite ways.

Il tutto come descritto, rivendicato ed illustrato, nei limiti del presente trovato, agli scopi sopra specificat All as described, claimed and illustrated, within the limits of the present invention, for the purposes specified above
