Definitions

  • This invention has, as a subject, a cast iron sleeper with built in anchorages (hooks) for rail track. It is known that - at present - the most used rail sleeper is in wood, of the most different kinds, suitably treated and processed, on which the track linking items are set.
  • the average life of the wood sleeper ranges between 15-20 years.
  • Said pre-compressed reinforced concrete sleeper has replaced wood in its function of stress distributor, but it has kept the need to separately arrange anchorages, prior to a preparation, seasoning, impregnation, and bituminization work on the sleeper; all this is definitely expensive.
  • the subject invention - obtained by casting - allows to obtain a rail sleeper 1 with well-defined mechanical characteristics, able to meet - in a very optimal way - the necessary principles of strenght and resistance of the track to the pressure specific stresses, distributing them on a wide surface, and allowing - by using anchorages 2 obtained by casting (in a single piece, with the rail track 1 casting) - the track locking by the classical dogs and plate system.
  • the cast iron rail sleeper 1 of the subject has a practically unlimited life, it does not need to be imported; thanks to its structure and shape, it optimally distributes stresses; it lends the track a strenght suitable to heavy and very fast traffic; it does not require the plates anchorages arrangement, since they already are obtained by casting.
  • the liquid cast iron - thanks to analyses suitable to the cast required mechanical characteristics - is poured in the mould, which - once the hardening process is finished - is shaken out and deburred. If necessary, a mechanical process is carried out to give anchorages (hooks) the precise required geometry in the coupling with fastening dogs.
  • said sleeper 1 can have any section (if anticipated cast anchorages (hooks) are built in).
  • said sleeper 1 can totally be hollow, with different thicknesses, and completely filled up with inert material (for example: sand), in order to dampen vibrations, and so obviously obtaining a lighter cast.
  • inert material for example: sand
  • Table 1 Figure 1 shows the sleeper 1 front view; Figure 2 shows a sleeper 1 cross section; Figure 3 shows the sleeper 1 upper view. Thickness, shape, length, sections - as shown in the drawing - represent one of the best solutions with respect to the functionality, the optimal shape, and also with respect to the overall weight.
