Abstract

The staircase has a central sleeve (13), a set of steps (10) respectively including treads (14) formed by disk sectors, and a fixation plate (12) connecting each step to the sleeve. Each step includes sections (22a, 22b) maintained on the corresponding plate and supporting each tread. Each plate includes longitudinal portions (36a, 36b) on which the sections of each step are maintained and extending in a plane perpendicular to the sleeve. The longitudinal portions of each plate forms an angle corresponding to an angle of each disk sector.
