Title (EN) RAILWAY BASEPLATE ASSEMBLY
(FR) ASSEMBLAGE PLAQUE DE BASE POUR VOIE FERREE
Abstract:
(EN) A railway baseplate assembly comprising a baseplate (30), a cushioning pad (20) for lying beneath the baseplate (30), and means (10) for securing the baseplate (30) to an underlying rail foundation when the assembly is in use, wherein the said securing means (10) comprise a non-screw-threaded post member (12), which post member (12) extends, when in use, through holes (21, 31) provided in the baseplate (30) and cushioning pad (20) in such a way as to engage the said baseplate (30). The post member (12) and baseplate (30) may be such that engagement of the baseplate (30) with the post member (12) can be brought about by movement of the baseplate (30) relative to the post member (12) firstly in a direction substantially perpendicular to the plane of the baseplate (30) and towards the post member (12) so that the post member (12) extends through the hole (31) in the baseplate (30) and secondly in a direction substantially parallel to the plane of the baseplate so that the post member (12) engages the baseplate (30). The post member (12) is fastened, directly or indirectly, to the rail foundation and the post member (12), cushioning pad (20) and baseplate (30) may be such that the cushioning pad (20) and baseplate (30) can be brought into engagement with the post member (12) while the post member (12) is fastened to the rail foundation.
(FR) L'invention concerne un assemblage plaque de base pour voie ferrée. Cet assemblage comprend une plaque de base (30), un coussin d'amortissement (20) destiné à être placé à côté de la plaque de base (30) et un moyen (10) permettant de fixer la plaque de base (30) à une fondation de la voie ferrée sous-jacente lorsque l'assemblage est utilisé, le moyen de sécurité (10) comprenant un élément plot (12) non fileté, celui-ci s'étendant, lorsqu'il est utilisé, à travers les trous (21, 31) situés dans la plaque de base (30) et dans le coussin d'amortissement (20) de façon s'engager avec ladite plaque de base (30). L'élément plot (12) et la plaque de base (30) peuvent être conçus d'une façon telle que l'engagement de la plaque de base (30) avec l'élément plot (12) peut être provoqué par mouvement de la plaque de base (30) par rapport à l'élément plot (12). Celui-ci est fixé, directement ou indirectement, sur la fondation de la voie ferrée et l'élément plot (12), le coussin d'amortissement (20) et la plaque de base (30) peuvent être conçus de façon telle que le coussin d'amortissement (20) et la plaque de base s'engagent avec l'élément plot (12) alors que celui-ci est fixé à la fondation de la voie ferrée.
