Definitions

  • the present invention will be of application in the railway multipurpose sleepers fabrication, with the object of obtaining sleepers that allow the placing of different track gage on them, both exclusively for RENFE gage or INTERNATIONAL gage, without modification of prestressing as an indistinctly multipurpose form for either one or another track gage through the corresponding adoption of the respective anchorings.
  • One of the methods more used is the one that corresponds to the Swedish Patent n° 7807242-8 applied by STRANGBETONG, STOCKHOLM on June 26, 1978 and granted on December 4, 1980, in which is claimed a "Method and device for elevating concrete elements, preferably prestressed” and essentially characterized for applying an lifting force among certain elements, and at the same time a support is introduced that absorbs the compression forces among the lower zones, preferably, the ends of two coinciding elements, in such a way that the produced moment in the lifting is balanced by the tractive forces in the reinforcement and the support compressive forces.
  • This method is subject to improvements or perfections, since with this method, the optimum results which are necessary for multipurpose sleepers are not obtained, as it is used with different track gages, the efforts to be supported do not correspond with total satisfaction when using one or the other gage.
  • the above mentioned multipurpose fabrication method is essentially formed by a special main function which consists in maintaining the elevated position of the sleepers, when the moulds are lowered and the prestressing force of the cables which form the reinforcement is transferred, and in controlling the prestressing force between the sleepers reducing to a minimum the displacement of the sleepers along the bedframe, which has a length of the order of 90 metres or more.
  • This new disposition of plates and compression members also guarantees a gradual transmission of the prestressing along the whole bedframe, for all the prestressing cables disposition of the multipurpose sleepers.
  • the new plates and compression element design absorbs all the prestressing force of the cables and provides stability against the possible rotation of the elements and at the same time it allows greater movements and maintains the correct position of the transverse beams.
  • the reinforcement always produced with prestressing cables, of different diameter in the upper and lower areas of the sleeper, is formed by four cables located in the upper area, of 3/8'' in diameter, and of eight of 1/4'' located in the lower area, by which it is obtained an improvement in adherence and a better distribution that facilitates the fabrication method.
  • the multipurpose sleepers are obtained, which may be used in RENFE track gage or in INTERNATIONAL gage, of 2,6 m in length, prestressed by pretensioned reinforcement by adherence and fabricated in long line, that largely satisfies the geometrical resistant and mechanical requirements for working in both gages, as it can be verified by the results of the last trials carried out on December 16, 1993.

  • the obtained sleeper by this fabrication method which constitutes the invention logically, besides being used in both gages (multipurpose) can be exclusively and indistinctively used in each one of the gages, without any prestressing modification, with the simple adoption of the corresponding anchorings.
  • This sleeper of 2,6 m in length presents basically a keystone-shaped section except in the ribs corresponding to the anchorings and it varies linearly among the different sections of the sleepers, in such a way that taking as a base the length thereof, the minimum section corresponding to the central, will have a small base of 0,0577, a large base of 0,0846 and a height of 0,0769, while the maximum section corresponding to the end will have a small base of 0,0823, a large one of 0,1154 and a height of 0,0942.
