Definitions

  • the object of the present application is the registration of a support device for bridges and viaducts.
  • the invention proposes the development of a support device provided in the construction of bridges and viaducts to dampen or transmit the forces that take place in the structure by terrain, climatological, environmental conditions, etc.
  • the bridges and viaducts are built in general on the basis of a set of vertical pillars that rest on their foundations, placing on said pillars some lintels that support a set of longitudinally arranged beams, which serve as support for the boards that constitute the platform on the one that builds a road through which vehicles, people, etc. circulate.
  • the boards can not be fully arranged because gaps are required where expansion joints must be installed to absorb the movements that occur due to temperature variations, braking effects and shrinkage of the concrete.
  • An example of known elastic supports is those that are constituted by a bowl that has a central recess inside which is lodged a discoidal pad made of an elastic material (such as, for example, chloroprene or natural rubber) that has a pressure behavior very good, behaving such material as a fluid when working in a visco-elastic state.

Abstract

Selon l'invention, un dispositif d'appui pour ponts et viaducs comprend un pot présentant un évidement où est logé un coussinet de forme discoïdale, une plaque piston placée au niveau supérieur par rapport au pot qui enveloppe le coussinet et des moyens d'étanchéité reliés au pot et à la plaque piston, lesdits moyens d'étanchéité étant compris entre des éléments annulaires se chevauchant et logés dans un enfoncement réalisé dans le coussinet et en contact avec la paroi latérale formée par l'évidement du pot, de manière qu'un élément annulaire inférieur est en contact avec le coussinet et un élément annulaire supérieur est en contact avec la plaque piston. Chacune des faces de l'élément annulaire supérieur et inférieur opposées présente une section étagée complémentaire l'une de l'autre, la face supérieure dudit élément annulaire supérieur présentant une surface inclinée en contact avec un enfoncement ayant un angle d'inclinaison complémentaire présent dans la plaque piston.
