Volte realine. Interventi di recupero e manutenzione

This paper refers to the analysis and characterisation of the so-called realine vaults, from a technical- constructive point of view. The realine vaults technique is a construction system for internal partitions used in the Western Sicily from the 18th century until the 1950s. Realine vaults are defined as a particular type of thin in folio vaults less than 10 cm thick. This type of technical element consists of thin clay bricks, measuring 12x25 cm and approximately 1 cm thick, laid with gypsum mortar to form several overlapping layers (the so-called in folio also used in other areas of the Italian peninsula), generally 2 or 3. As in the case of the bóvedas tabicadas typical of the Iberian area and from which the vaults in question are said to derive, the realine vaults resistance is due, not only to their material, but above all to their shape. Moreover, their cohesive behaviour follows the theory postulated by R. Guastavino Moreno. After an examination of the geometric characteristics and structural behaviour, made possible thanks to an extensive survey carried out in the Palermo area, the article describes the possible interventions, already put into practice or
