Abstract

La présente invention concerne une structure porteuse pivotante (16) destinée à des modules solaires ou photovoltaïques (6) comprenant au moins un arbre porteur et/ou pivotant (18) qui supporte au moins un module solaire ou photovoltaïque (6). L'arbre (18) comporte au moins deux tubes (20a, 20b, 20c) d'arbre porteur et/ou pivotant se raccordant sans déport bout à bout l'un à l'autre. Entre le ou les premiers tubes (20a) et le ou les seconds tubes (20b) des deux tubes (20a, 20b, 20c) d'arbre porteur et/ou pivotant ou plus peut être réalisée une liaison solidaire en rotation au moyen d'un manchon de liaison (22) formé d'au moins deux parties (24, 24').
