Recenti studi hanno confermato come la diffusione nella Sicilia occidentale delle volte sottili di mattoni in foglio (“realine”) sia avvenuta in maniera estesa dalla seconda metà del secolo XVIII ai primi decenni del Novecento, sia negli orizzontamenti e nelle scale dell'edilizia corrente, che con funzione portante e di soffittatura nelle architetture nobiliari. Per finalità di studio o professionali se ne sono analizzati i caratteri costruttivi, le costanti e le variabili, con verifiche su strutture che hanno superato indenni le prove del tempo. In laboratorio o nei cantieri sono state effettuate sperimentazioni accademiche ed interventi di recupero, con ricostruzioni parziali o totali e interventi di "miglioramento statico". I confortanti risultati delle prove di carico sulle volte intatte e su volte-campione costruite a piè d’opera o in laboratorio supportano la scelta della ricostruzione e dimostrano come istruire le maestranze alla padronanza di tecniche desuete comporti un limitato impegno economico e di tempo, a vantaggio della qualità dell’intervento e del rispetto della storia: la conoscenza costruttiva infonde fiducia nelle prestazioni delle volte sottili. Anche nell'evoluzione normativa la demolizione generalizzata gradualmente volge nella direzione del mantenimento, talvolta svincolando le volte dalle originarie funzioni statiche.

Abstract
Recent studies have confirmed that the spread in Western Sicily of tiled vaults ("realine") took extensively place from the second half of the XVIII century to the first decades of the XX century, both for floorings and staircases in the basic building and with a load-bearing or ceiling function in the noble architecture. The constructive characters have been analyzed for study or professional finalities, likewise the constants and variables, with checks on that unscathed structures during the time. Academic experiments and recovery interventions were performed, in laboratory or in the restoration yards, with partial or total reconstruction and "static improvements"; the encouraging results of the load tests on the intact vaults and on example-vaults, built on site or in the laboratory, support the choice of re-construction and demonstrate how the instruction of workers to the competence of obsolete techniques involves a limited financial and temporal commitment, taking a quality of the intervention and the respect of history: the constructive knowledge instils confidence in the performance of tiled vaults. According to the evolution of regulations, the general demolition gradually gives way to maintenance, sometimes releasing these vaults from their original static functions.File | Dimensione | Formato | |
