Description
DESCRIZIONE DESCRIPTION
L'invenzione presenta un metodo ed un prodotto per risolvere il problema rappresentato dalla facilità di rottura e collasso di lastre di marmo sottili sollecitate a flessione ed urto. The invention presents a method and a product for solving the problem represented by the ease of breaking and collapsing of thin marble slabs subjected to bending and impact.
SETTORE TECNICO DI APPLICAZIONE TECHNICAL FIELD OF APPLICATION
L'invenzione trova uso ed applicazione nel campo dell'edilizia e dell'arredamento in cui lastre di marmo sono usate come rivestimento, come separazione di spazi abitativi o anche semplicemente come ornamento. STATO DELLA TECNICA ANTERIORE The invention finds use and application in the field of construction and furniture in which marble slabs are used as cladding, as a separation of living spaces or even simply as an ornament. STATE OF THE PRIOR ART
Come noto, il materiale lapideo presenta buone proprietà di resistenza a compressione, ma scarsa resistenza a trazione. Accade quindi che una lastra di tale materiale si rompa facilmente se sollecitata a flessione e tanto più facilmente, a parità di sollecitazione, quando la sua struttura non sia omogenea ma presenti delle disuniformità: dai punti deboli della struttura, in caso di sollecitazioni, tendono a partire delle crepe che sono innesco a successive rotture. As known, the stone material has good compressive strength properties, but poor tensile strength. It therefore happens that a sheet of this material breaks easily if stressed by bending and all the more easily, with the same stress, when its structure is not homogeneous but presents some non-uniformity: from the weak points of the structure, in case of stress, they tend to leave cracks which trigger subsequent breakages.
La capacità di resistere ad un carico flessionale si può accrescere aumentando lo spessore delle lastre, oppure rinforzando le lastre stesse mediante applicazione di rinforzi strutturali. The ability to withstand a bending load can be increased by increasing the thickness of the sheets, or by reinforcing the sheets themselves by applying structural reinforcements.
La prima via trova i suoi limiti nel peso; la seconda presenta soluzioni anche molto interessanti, dovute alle speciali caratteristiche di alcuni materiali strutturali usati, come le strutture a nido d'ape. Ed in alcuni casi si è ottenuto un discreto miglioramento strutturale incollando due lastre di marmo una sull'altra, producendo una sorta di "compensato" in cui le superfici trasversali su cui si propagherebbero le rotture in una delle lastre, non trovano continuità nell'altra e ne vengono di conseguenza ostacolate nella propagazione. The first way finds its limits in the weight; the second also presents very interesting solutions, due to the special characteristics of some structural materials used, such as honeycomb structures. And in some cases a moderate structural improvement has been obtained by gluing two marble slabs on top of each other, producing a sort of "plywood" in which the transverse surfaces on which the cracks in one of the slabs would propagate, do not find continuity in the other. and consequently they are hindered in propagation.
Su questa linea si è mosso questo inventore che, individuato il punto di debolezza nella soluzione sopra descritta, dovuta a suo parere, nella fragilità del collante, propone un metodo nuovo di accoppiamento che conferisce al prodotto eccezionali caratteristiche di resistenza a flessione e, in caso di rottura, ne impedisce o comunque ritarda il collasso. This inventor has moved along this line who, having identified the weakness in the solution described above, due in his opinion, to the fragility of the adhesive, proposes a new coupling method that gives the product exceptional characteristics of resistance to bending and, in case of rupture, it prevents or in any case delays its collapse.
DESCRIZIONE DELL'INVENZIONE DESCRIPTION OF THE INVENTION
Fra due lastre di materiale lapideo si interponga uno strato di materiale tenace e non fragile, resistente alla trazione ed allo scorrimento; questo materiale sia incollato stabilmente alle superfici omologhe delle due lastre; si otterrà un accoppiamento tenace e non fragile fra le due lastre, che ne accrescerà in modo notevole la resistenza a sollecitazioni flessionali. Between two slabs of stone material a layer of tough and non-fragile material, resistant to traction and sliding, is interposed; this material is stably glued to the homologous surfaces of the two slabs; a tough and non-brittle coupling will be obtained between the two sheets, which will significantly increase their resistance to bending stresses.
Nel caso che tali sollecitazioni fossero tali da creare delle crepe o rotture in una delle due lastre, il materiale interposto impedirà la propagazione della rottura sull'altra lastra; nel caso che le sollecitazioni fossero tali da creare rotture su una o su ambedue le lastre, il materiale interposto, incollato sulle superfici delle lastre stesse, ne impedirà la frammentazione ed il collasso. Concettualmente, si tratta di applicare per la prima volta a due lastre di marmo il principio attuato ad esempio nei vetri di sICurezza antisfondamento, senza il limite della trasparenza o del colore e quindi dei materiali adatti allo scopo: la soluzione qui proposta considera infatti, in un caso particolarmente, l'uso di un tessuto come materiale interposto; un tessuto è talvolta adottato nell'accoppiamento di marmi alleggeriti con la struttura di rinforzo, ed è oggetto di brevetti anche di questo inventore. If these stresses are such as to create cracks or breaks in one of the two slabs, the interposed material will prevent the propagation of the break on the other slab; if the stresses were such as to create cracks on one or both slabs, the interposed material, glued on the surfaces of the slabs themselves, will prevent fragmentation and collapse. Conceptually, it is a question of applying for the first time to two marble slabs the principle implemented, for example, in safety glass, without the limit of transparency or color and therefore of materials suitable for the purpose: the solution proposed here in fact considers, in fact, in one particularly, the use of a fabric as an interposed material; a fabric is sometimes adopted in the coupling of lightened marbles with the reinforcement structure, and is also the subject of patents of this inventor.
UN MODO ESEMPLARE DI APPLICAZIONE DEL TROVATO Dopo sperimentazioni con vari materiali e dettagliate prove di laboratorio, questo inventore ha individuato una applicazione ottimale del trovato usando come collante una resina epossidica e come materiale interposto un tessuto in fibra di vetro. Il tessuto viene interposto fra le facce di due lastre su cui è steso uno strato di resina; l'insieme, stretto a pressione adeguata, viene posto in forno per un tempo e ad una temperatura ottimali per la maturazione della resina. La resina indurita "inchioda" quindi le facce esterne del tessuto sulle due superfici lapidee, creando di conseguenza un legame molto stabile e rigido fra la faccia esterna del tessuto stesso ed il materiale lapideo, mentre la parte interna del tessuto mantiene la sua interconnessione tenace e stabile ma non rigida. Ne consegue che, quando il sandwich così ottenuto viene sollecitato a tlessione, mostra una resistenza alla tlessione molto maggiore di una lastra singola o di due lastre incollate di pari spessore; superato che sia tale limite di resistenza, la lastra soggetta a trazione si fessura, ma la crepa non si trasmette all'altra lastra né si verifica una caduta dei frammenti. AN EXAMPLE WAY OF APPLICATION OF THE FINDING After experimentation with various materials and detailed laboratory tests, this inventor has identified an optimal application of the invention using an epoxy resin as glue and a fiberglass fabric as an interposed material. The fabric is interposed between the faces of two plates on which a layer of resin is spread; the whole, tightened under adequate pressure, is placed in the oven for an optimal time and temperature for the resin to cure. The hardened resin then "nails" the external faces of the fabric on the two stone surfaces, consequently creating a very stable and rigid bond between the external face of the fabric itself and the stone material, while the internal part of the fabric maintains its tenacious and stable but not rigid. It follows that, when the sandwich thus obtained is stressed to tensile stress, it exhibits a much greater tensile strength than a single slab or two glued slabs of equal thickness; once this limit of resistance is exceeded, the sheet subject to traction cracks, but the crack is not transmitted to the other sheet nor does a fall of the fragments occur.
