Definitions

  • connection zones 9a, 9b of the branches 1 1a, 1 1b of the gutter 3 with the bottom 13 of this gutter are areas of high stress concentration.
  • this circular configuration of the main portion 14 is not ideal to allow the attachment of the rail according to the invention to a fixed girder girder: such a circular configuration has the effect of limiting the extent of the contact area of the rail with the corresponding part of the beam.
  • FIGS. 10 to 12 show various fastening means of the rail according to the invention on the associated web 1 of the beam 23, which can be used alone or in combination with the one conq ue of the embodiments of embodiments shown in Figures 2 to 9.
  • the reinforcing portion 1 5 allows the integration of these fastening means.
  • these wires 35 can also pass through the web 1, and thus make it possible to reinforce the fixing of the rail 3 on this web. Martyr zones can be added for an improvement of the production cycle (installation of reinforcing threads directly in the polymerization tool).
  • a material addition (called “nail head”) may be required, as indicated by reference numeral 45 in FIG.
