Abstract

L'invention concerne un module de plateau de câbles pour canalisations de câbles et analogues en forme de U délimitant une paroi de fond plane et des parois latérales qui présentent une première section avec une terminaison de renfort/accouplement et une seconde section au niveau de laquelle les parois latérales sont droites avec une hauteur inférieure à celle de la première section, le module comprenant une rainure d'accouplement et des extrémités qui sont conçues pour l'accouplement mâle-femelle avec un module de plateau adjacent. De manière avantageuse, la rainure d'accouplement est constituée d'une découpe longitudinale qui s'étend perpendiculairement depuis un de ses côtés d'extrémité en passant par la ligne de pliage.
