Abstract
The invention relates to a span (2) for railway tracks with a self-supporting U-shaped structure (3), defining a section of the path for a piece of rolling stock (1), travelling on the railway track and at least one further element (6, 10, 11, 14) for the travel of the rolling stock (1) on the railway track and which can support, guide and/or supply the rolling stock (1). According to the invention, at least one (6) of the additional elements (6, 10, 11, 14) is directly integrated in the U-shaped element (3).
Claims11
A span for a railway track, said span comprising:
- a prefabricated U-shaped structure made of concrete, defining a portion of a path for a piece of rolling stock running on the railway track, said prefabricated U-shaped structure having a sidewall and a horizontal slab, said horizontal slab including a running rack configured to support said piece of rolling stock;
- and
- at least one side rail which enables movement of the rolling stock on the railway track and which is adapted to provide the rolling stock with at least one of a guiding service and a powering service, said at least one side rail being fastened to said side wall of the U-shaped structure by fastening members, and said fastening members including a support which is fastened directly to the side wall and which supports said at least one side rail,
- said horizontal slab of said prefabricated U-shaped structure configured to be directly supported by a first pier and a second pier of a viaduct, and run between said first and second piers.
An assembly for a railway track comprising piers and a span, said span comprising:
- a prefabricated U-shaped structure made of concrete, and defining a portion of a path for a piece of rolling stock running on the railway track, said prefabricated U-shaped structure having a side wall and a horizontal slab, said horizontal slab including a running rack configured to support said piece of rolling stock;
- and
- at least one side rail which enables movement of the rolling stock on the railway track and which is adapted to provide the rolling stock with at least one of a guiding service and a powering service, said at least one side rail of the railway track being fastened to the side wall of the U-shaped structure by fastening members, said fastening members including a support which is fastened directly to the side wall and which supports said at least one side rail;
- said horizontal slab of said prefabricated U-shaped structure configured to be directly supported by the piers.
A span for a railway track, said span comprising:
- a prefabricated U-shaped structure made of concrete, defining a portion of a path for a piece of rolling stock running on the railway track, said prefabricated U-shaped structure having a sidewall, a horizontal slab, and supports for rails, said horizontal slab of said prefabricated U-shaped structure configured to be directly supported by a first pier and second pier of a viaduct, and run between said first and second piers, said horizontal slab including a running rack configured to support said piece of rolling stock.
An assembly for a railway track comprising a first pier, a second pier and a span, said span comprising:
- a prefabricated U-shaped structure made of concrete, defining a portion of a path for a piece of rolling stock running on the railway track, said prefabricated U-shaped structure having a sidewall and a horizontal slab, said horizontal slab including a running rack configured to support said piece of rolling stock;
- and
- rails assembled to said prefabricated U-shaped structure;
- said horizontal slab of said prefabricated U-shaped structure configured to be directly supported by said first pier and said second pier, and run between said first and second piers.
A span for a railway track, said span comprising:
- a prefabricated U-shaped structure made of concrete, defining a portion of a path for a piece of rolling stock running R on the railway track, said prefabricated U-shaped structure having supports for rails, sidewalls with a upper end, and a horizontal slab, said horizontal slab of said prefabricated U-shaped structure configured to be directly supported by piers, wherein the side walls are shaped so that the upper end substantially reaches a level of a deck of the rolling stock, said horizontal slab including a running rack configured to support said piece of rolling stock.
A span for a railway track, said span comprising:
- a prefabricated U-shaped structure made of concrete, defining a portion of a path for a piece of rolling stock running on the railway track, said prefabricated U-shaped structure having supports for rails, sidewalls with a upper end, and a horizontal slab, said horizontal slab of said prefabricated U-shaped structure configured to be directly supported by piers, wherein the side walls form the edge of a station platform, said horizontal slab including a running rack configured to support said piece of rolling stock.
