Abstract

La présente invention concerne un support (10) comportant au moins une rangée (13) de segments (15) juxtaposés, la rangée (13) s'étendant de préférence d'une extrémité (21a) du support (10) à une extrémité (21b) opposée du support (10). Dans un mode de réalisation préféré, au moins un élément de serrage (14) s'étend à travers la rangée (13), qui peut en outre être désigné en tant que tirant d'ancrage et qui est ancré aux extrémités (25a, b) de la rangée (13) et est serré contre la rangée (13) pour maintenir les segments (15) de la rangée (13) ensemble. Les segments (15) adjacents sont serrés l'un contre l'autre au niveau de leurs faces latérales (24) au moyen du ou des éléments de serrage (14), un ou plusieurs ou aucun élément, tel que par exemple une feuille métallique, pouvant être disposé(s) entre les faces latérales (24). La liaison des segments (15) adjacents de la rangée (13) est de préférence si élevée, en raison de la polarisation du ou des éléments de serrage (14) de la rangée (13) par rapport à la rangée (13), qu'un autre moyen de liaison permettant de lier les segments (15) adjacents de la rangée (13) n'est pas nécessaire. Par conséquent, de préférence il existe aucune liaison de matière, par exemple aucune liaison soudée et/ou aucune liaison vissée entre deux segments (15) adjacents d'une rangée (13) permettant de lier les segments (15) adjacents, laquelle est soumise à une charge de traction, lors de l'utilisation fonctionnelle du support (10) monté dans un dispositif (33, 34), le long de l'étendue longitudinale de la rangée (13). Le support (10) peut être produit dans un lieu de mise en œuvre, auquel les segments (15) individuels sont transportés et dans lequel lesdits segments sont disposés en rangée (13) et serrés au moyen de l'élément de serrage (14).
