Progetto di un sistema costruttivo industrializzato a secco con caratteristiche massive

This paper presents a new dry construction system based on a modular wooden frame braced by massive infill assembled without the use of mortar. Proper cohesion to the system is then given using a post-compression system made with steel rods. The studied construction system follows specific "guidelines": industrialization of the building process, modularity, temporality, adaptability, mutability, replicability, sustainability. The conception of this work finds its roots in the historical constructive tradition recalling Portuguese “gaiola” or “casa baraccata”. While sticking firm to these original construction principles, which have become the basis of the first anti-seismic regulations, the proposed system has been actualized trying to overcomethose traditional building techniques that nowadayscharacterize a very rigid and unchanging market such as construction industry. It consists therefore of a massive construction system, in which most of the processing takes place in factory in order to reduce and speed up on site operations. Specific attention was paid to materials selection choosing those more sustainable from an environmental and economic point of view. The research has developed primarily around the design of the dry-assembled cooperating infill wall that is conceived as a means to ensure both climatic and mechanical efficiency, both to guaranteetime and cost reduction. This innovative infill, of which was calculated the insulating behaviour in various Italian provinces during different months of the year, has been included in a modular wooden 4x4 meters step frame suitably designed and verified for static loads. It was thus possible to define a basic module of the building system, easily repeatable and combinable, with which more complex residential buildings can be designed, rapidly realizableand adaptablethrough time to changing user needs.
