  • the first arc is in the first plane
  • the second arc is in the second plane.
  • the first and second legs extend at least approximately parallel to one another and / or wherein the first leg and second leg have at least approximately the same length.
  • the third leg extends at an acute angle or at least approximately parallel to the second leg.
  • first arc and the second arc on the same bending radius.
  • the first and second sheets may be semicircular or Quarter-circle, in which case two quarter-circular arcs are connected via a straight leg. In the latter embodiment can also be spoken by a web.
  • FIG. 1 is a cross section through a track cutout of a railway sleeper shown.
  • a rail 2 is fixed on a ribbed plate 5 by means of rail pins 7.
  • the rail pins 7 protrude through openings 50 in the fin plate and extend into holes 3 which are mounted in the threshold 1, wherein the rail pins 7 are fixed in the holes 3.
  • a spreader insert 4 is sunk in each case for fixing the rail nails 7 in the bores 3 and optionally encapsulated by means of a potting compound 6 in this waterproof.
  • the rail pins 7 clamp the rail 2 to the threshold 1 or Ribbed plate 5.
  • FIGS. 2 to 4 is an embodiment of a rail nail 7 for use in the track construction after FIG. 1 shown.
  • the rail nail 7 comprises a head section 70, a shaft section 71 adjoining thereto, and a nail tip section 72, which adjoins the shaft section 71.
  • the nail tip section 72 terminates with a nail tip 73.
  • the shaft section 71 and nail tip 72 extend along a central axis M.
  • the head section 70 comes into contact with the rail 2 and clamps it against the ribbed plate 5.
  • the shaft section 71 protrudes the receiving opening 50 in the ribbed plate 5 through and extends into the bore 3 in the threshold.
  • the shank portion 71 has a square or rectangular cross section.
  • the shaft portion 71 may also have a circular cross-section.
  • the nail tip portion 72 is formed so that the cross section of the nail tip portion 72 seen from the shaft portion 71 forth, is continuously reduced.
  • the degree of reduction over the nail tip portion 72 from the shaft portion 71 to the nail tip 73 is constant.
  • the nail tip 73 may have a variety of different shapes. In the present embodiment, this is provided with a convex edge.
  • Such a rail nail 7 typically has a diameter in the range of 14 to 19 mm, in particular 16 mm and a length in the range of 130 to 180 mm, in particular 165 mm.
  • the inventive spreading insert 4 is shown. It is bent from a one-piece rod material, preferably made of special steel, as it can also be used for reinforcing iron.
  • the spreader insert 4 has three legs 40, 41, 42, which are slightly resilient to each other are formed.
  • a first and a second leg 40, 41 extend at least approximately, here exactly, parallel to each other.
  • the first and second legs 40, 41 are connected to each other via a first arc 43.
  • the first leg 40 and the second leg 41 lie in a common first plane E1. This means that, for example, the central axes along which the legs 40, 41 are part of this first plane E1 and define this first plane E1.
  • This first level E1 runs in the FIG. 6 in the plane of the drawing sheet and is indicated by a dash E1 in the FIG. 5 indicated.
  • the first arc 43 is formed in the first plane E1 of the two legs 40, 41 bent, as best in FIG. 9 is recognizable.
  • the second leg 41 is followed by a second arc 44, which is then followed by the third leg 42.
  • the third leg 42 lies in a second plane E2, which is perpendicular to the first plane E1.
  • the second plane E2 is such that it extends through the de second leg 41, so that the third leg 42 comes to rest on the second leg 41.
  • the second level E2 is in the FIG. 5 shown accordingly. Because of this arrangement, the inventive spreader 4 can be used for rail nails, since the spreader insert is inserted into the bore 3, that all three legs 40, 41, 42 are in contact with the wall of the bore 3 and none of the cross section of the bore more than necessary reduced.
  • the rail nail can be driven in well without requiring too much deformation of the spreader pad, as occurs, for example, in prior art embodiments.
  • the rail nail is not deflected from its axis during the process of driving.
  • the legs are pressed into the side wall of the bore. Consequently, the rail nail 7 and the spreader pad 4 are clamped together in the bore.
  • the first leg 40 has a first free end 46, which at least approximately, preferably exactly, forms a rectilinear extension of this leg 40.
  • the third leg 42 has a second free end 45, which at least approximately, preferably exactly, forms a rectilinear extension of this leg 42.
  • the third leg 42 adjoins a Verharkungsabêt 47, which angled, preferably perpendicular, from the third leg 42 protrudes and preferably in the second plane E2 extends.
  • the Verharkungsabites 47 is pressed by the breaking of the rail nail in the wood of the threshold, so the resistance to pulling can be further increased.
  • the first leg 40 may comprise a not shown here Verarkungsabêt, which is formed analogous to the Verharkungsabites 47.
  • the second leg 41 is preferably longer than the first leg 40, as shown in FIG. 2 is recognizable.
  • the third leg is preferably formed shorter than the two other legs 40, 41. However, it preferably extends over at least two-thirds of the length of the spreader 4.
  • the third leg 42 may extend at an acute angle to the second leg 41, as best shown in FIG. 3 is recognizable. Both embodiments are advantageous because both provide a very compact structure.
  • the first arc 43 and the second arc 44 have the same bending radius, which is advantageous with respect to the compact structure. Due to the arrangement of the first sheet 43 and the second sheet 44, the spreader insert can be made very compact, which allows the introduction into holes 3, which have a relatively small diameter, as is common in holes for rail nails.
  • the first leg 40 typically has a length from the free end 46 to the first arc 43 of 75 to 105 mm. Particularly preferred is a length range between 78 and 98 mm, in particular 93 mm.
  • the second leg 41 typically has a length from the first arc 43 to the second arc 44 of 90 to 120 mm. Particularly preferred is a length range between 95 and 110 mm, in particular 100 mm.
  • the third leg 42 typically has a length from the free end 45 to the second arc 44 of 65 to 100 mm. Particularly preferred is a length range between 83 and 93 mm, in particular 88 mm.
  • Both sheets 43, 44 preferably have a radius of 6 to 12 mm, more preferably 8 to 10 mm, in particular 9 mm.
