Support for a panel of a section of guided transport track

Abstract

The invention relates in particular to a guided transport track section intended to be fixed to a ballastless track formation (15), characterised in that said section comprises: a track panel (20) comprising two stringers (21, 22) and at least one structure transverse to the stringers (23, 24), each stringer (21, 22) comprising an upper longitudinal groove (25) for receiving a rail; a plurality of panel supports (31, 32, 33, 34), each support comprising at least one stud (35) for fastening to the track formation, a cradle (37) for supporting a stringer (22) that is mounted so as to be movable vertically in said stud (35), and means for vertical movement of said cradle (37) relative to said stud (35) so that the height of the panel (20) relative to said track formation (15) can be adjusted, and the superelevation of the track section thus formed can be defined by means of coordinated adjustment of the various cradles (37).

Description

1. TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to ballastless tracks for guided transport vehicles, such as railway vehicles or pneumatic vehicles. The invention relates more particularly to a support for the guided transport track sections allowing the formation, by means of successive arrangement of a plurality of sections, of a ballastless track, a corresponding track section and a corresponding ballastless track.2. TECHNICAL BACKGROUND[0002]Since railway tracks have existed, it has been known to install these tracks on ballast, that is to say on a bed of crushed stones or of gravel. The ballast allows the forces transmitted by the sleepers under the action of the moving loads to be distributed across the underlying track formation. The ballast therefore allows the compaction of the track formation to be reduced. Lastly, the ballast allows the sleepers to be embedded in order to restrict their movements and their deformations.[0003]For several years, there has bee...

AI Technical Summary

Benefits of technology

The invention is about a device used to lock a cradle in place. The device includes an adjustment screw that is inserted into a stud and comes into contact with the cradle to prevent any horizontal movement. The invention also usesH-shaped section profiles to help withstand the process of driving the placement elements into the track formation. This makes the device more stable and reliable.

Problems solved by technology

One of the difficulties encountered during the production of a ballastless track of this kind is the precision required when the concrete slabs are laid on the underlying foundation layer because this precision directly determines the track geometry.

The adjustment of the distance between track centre lines may also pose technical problems.
