Abstract: A silo (1), in particular a vertical one, designed to store products in powder form, and having a vibrating bottom (3), suitable for favoring flow, and for equipping a fixing damper body (2) of a silo (1) by means of a joining element (9) and a fixing damper (10), provided to ensure a tight connection between the body of the silo and the vibrating bottom, while, at the same time, preventing a transmission of vibrations from one to the other. According to the invention, the joining element (9) takes the form of an elastically deformable, peripheral, self-supporting joint, interposed directly and freely between the body (2) of the silo (1) and the vibrating bottom (3), cooperating with the fixing damper (10) to perform both a sealing function and a damping function, without discontinuity over its entire bearing periphery.
