Abstract

La presente invenzione riguarda un sistema di protezione catodica di strutture in calcestruzzo armato comprendente l'applicazione di una struttura anodica costituita da file di strisce di metallo valvola attivate da un rivestimento catalitico aventi aperture, e supportate da spaziatori costituiti da elementi prefabbricati di materiale cementizio caratterizzati dal fatto di comprendere fibre disperse continue o a rete non conduttrici o materiale polimerico; dette strisce essendo collegate tra loro da elementi di collegamento quali tondini, barre, cavi metallici isolati. La struttura così formata viene inglobata nello stesso calcestruzzo durante la costruzione delle strutture in cemento armato.The present invention relates to a cathodic protection system of reinforced concrete structures comprising the application of an anodic structure consisting of rows of valve metal strips activated by a catalytic coating having openings, and supported by spacers consisting of prefabricated elements of cementitious material characterized by the fact that it comprises continuous or non-conductive dispersed fibers or polymeric material; said strips being connected together by connecting elements such as rods, bars, insulated metal cables. The structure thus formed is incorporated into the same concrete during the construction of the reinforced concrete structures.
