Connection between core and armatures of structures comprising a core of agglomerated fibres

摘要

Structure intended to transmit great mechanical stresses, comprising an elongated core comprising at least an agglomerated glass fibre rod and fixing armatures fitted to the ends of the core, comprising means exerting radial compression stresses or stresses tending to jam the rod and maintaining at least partly those efforts in a zone of the structure situated in the armatures, even when the structure is not subjected to mechanical stresses. The structure has application to insulators for electric apparatus, stays, suspension of electric power conveying lines. PPFIELD OF THE INVENTIONP PThe present invention concerns a structure intended for transmitting great mechanical stresses, comprising an elongated core comprising at least one rod of agglomerated glasse fibres and fixing armatures fitted to the ends of the core, by means of which the mechanical efforts are transmitted. It relates more particularly to an improvement in the connection between core and armature of such structures.
