CA 2456145

The invention is a support structure (150) for a railed-vehicle (54) that includes individual, unassembled components sized for easy transport. In one embodiment, the support structure (150) includes curved columns (160) integrally-formed with a base (162), the columns imparting a curved, Y- shaped configuration to the support structure (150). The components may be prefabricated with known materials and methods and transported to an installation site for assembly. The support structure (150) is preferably sized to support one or two vehicle guideways (152). The support structure (150) may include a pile foundation (56b) for improved support during seismic activity and to facilitate installation on existing streets and sidewalks without covering or interfering with underground plumbing or utilities. Preferably, multiple sections of the guideway (152) are rigidly secured together through expansion joints to define a continuous guideway (152) such that loads on the guideway are distributed over multiple columns (160).

L'invention porte sur une structure support pour véhicules sur rails composée d'éléments individuels non assemblés d'une taille en facilitant le transport. Dans une exécution, ladite structure consiste en poteaux incurvés d'une seule pièce avec leur base présentant une configuration incurvée en Y. Les composants, préfabriqués à l'aide de matériaux et de procédés usuels, sont transportés sur le chantier pour y être assemblés. La structure support, de préférence dimensionnée pour supporter une ou deux voies, peut comporter une fondation assurant une stabilité améliorée en cas d'activité sismique, et facilitant l'installation dans des rues et sur des trottoirs existants sans recouvrir les canalisations souterraines ni interférer avec elles. Les différentes sections de la voie sont de préférence reliées rigidement entre elles par des joints de dilatation de manière à constituer une voie continue permettant de répartir les charges sur plusieurs poteaux.
