Abstract

La présente invention a trait à un appareil permettant de fabriquer un poteau électrique doté de plateaux supérieur et inférieur améliorés et à un procédé permettant de fabriquer le poteau électrique à l'aide de celui-ci et, plus particulièrement, à une structure qui compense un déficit dans le mortier du béton se produisant au niveau de l'extrémité du plateau inférieur en raison du serrage du béton par la force centrifuge et à une structure qui est divisée en deux plateaux de renforcement supérieurs et plateaux de support supérieurs, contrairement à l'art antérieur où le plateau supérieur est une unité unique, ce qui permet de la sorte de diviser son poids en vue de faciliter le maniement au cours de l'assemblage et du désassemblage du poteau électrique. De plus, des boulons d'articulation de tension qui sont insérés dans des rainures d'insertion dans chacune des extrémités des plateaux inférieur et supérieur sont utilisés afin de fixer les deux extrémités d'une barre de tension, et la direction des boulons d'articulation de tension correspond à la direction agencée de la barre de tension de manière à minimiser toutes les pertes de la force de traction qui est appliquée à la barre de tension.
