Abstract

La présente invention concerne un système comportant un organe à protection antisismique (1) intégré à une installation industrielle, érigé à la façon d'un mât ou d'une tour. L'invention concerne de préférence un système destiné à la protection d'un organe correspondant (1) d'une installation de production, de distribution ou de transformation électrique. La base de l'invention est un système dans lequel l'organe à protection antisismique concerné (1) est ancré dans le sol (4) par un massif de fondation ou est fixé au sol (4), ou à un autre organe de l'installation, par l'intermédiaire d'un élément de fixation (3). Pour réaliser la protection antisismique, l'invention propose de monter simplement un ressort hélicoïdal (2) disposé verticalement entre, d'une part le massif de fondation ou l'élément de fixation, et d'autre part l'organe à protection antisismique (1). Un assemblage à force et/ou par complémentarité de forme permet de réunir le ressort au massif de fondation ou à l'élément de fixation (3) ainsi qu'à l'extrémité axiale inférieure de l'organe antisismique (1), le ressort hélicoïdal (2) subissant en cas de séisme une charge en compression, c'est-à-dire dynamique, exclusivement verticale, et en flexion.
