Definitions

  • the invention relates to a bearing for a track section comprising running along the track section and receiving these under plates such Rail fastening or rib plates, with between the respective base plate and an associated intermediate support such as a threshold or concrete slab made of elastic material such as B. from elastomers such as polyurethane elastomers is arranged, the spring stiffness is approximately area-dependent with respect to the changes respective effective support surface of the base plate on the intermediate plate.
  • elastic intermediate plates are used between the base plates that hold the track, such as ribbed plates and the support arranged like sleepers or concrete slabs, with an application both in Ballast track as well as on a solid road.
  • the ones used elastic intermediate layers consist of cellular elastomers such as PU foams, which have a spring stiffness that is approximately linearly dependent on the contact surface of the Base plate is. This means that for base plates with different ones Intermediate layers of different thicknesses are used must have the same elastic behavior in the track, i.e. the same To have spring stiffness in the respective intermediate layers.
  • Superstructure constructions with elastic intermediate layers are e.g. B. EP 0 666 938 B1 or in DE 44 06 105 A1. You can use it to store the base plates Spring systems with an overall characteristic curve with a kinked curve in such a way Use that when the force applied to the spring system is smaller than that in the Working area is force, the characteristic increases steeply and in the working area runs flat.
  • a base with an elastic intermediate layer is known from EP 0 546 363, whose spring stiffness can be changed depending on the contact force so that the entire Contact surface of the intermediate layer with increasing angle ⁇ starting from the The central axis of a rail section increases continuously.
  • the present invention is based on the problem of storing the input mentioned type with an intermediate plate made of elastic material, the spring stiffness depending on the effective support surface acting on the intermediate layer the base plate changed in an approximately linear relationship, to further develop that regardless of the size of the base plate the same dimensioned intermediate layers can be used without different spring stiffness surrender.
  • the problem is essentially solved according to the invention in that between the Base plate and the intermediate layer an intermediate plate with a the base plate ablating surface, the extent of which faces regardless of the intermediate layer load-bearing bottom surface of the base plate.
  • a load is transferred from the rail fastening and ribbed plate to the elastic intermediate layer over a defined area, so that as a result the spring stiffness of the intermediate layer does not depend on the size of the rail mounting plate itself is dependent.
  • Dimensions of intermediate layers made of cellular elastomers such as PU foams are used that have the same material properties.
  • Appropriate PU foams are commercially available for. B. under the name Sylomer® or Sylodyn® offered.
  • the liner itself consists, for. B. made of rigid plastic or metal Sheet metal or other suitable material.
  • the intermediate layer is perpendicular to the support in the area running projection of the track section or its rail foot one Has cutout, which in the respective longitudinal edge regions of the rail foot and in the longitudinal direction of the track section extending strip-shaped sections of the Liner is limited.
  • the rail experiences in the area of its longitudinal edges
  • a targeted support such that undesired tilting is prevented.
  • the intermediate plate has a peripheral edge strip with the preferably central cutout and others in the area of the base plate connecting elements connected to the support, such as bolts Has cutouts.
  • the other cutouts can each be U-shaped Show geometry.
  • the intermediate layer itself is in particular symmetrical to its longitudinal axis. Furthermore, there should also be symmetry parallel to the longitudinal direction of the rail section transverse axis. Even if preferably one the teaching according to the invention also includes a symmetrical design asymmetrical shapes that are used especially in the area of switches can.
  • the intermediate plate preferably has a removal area of preferably approximately 400 cm 2 .
  • customary rail fastening and track plates of a load-bearing floor area between preferably 400 and 1,400 cm 2 can be covered.
  • the cellular elastomers used such as polyurethane elastomers themselves have a spring stiffness or number in the range between 5 kN / mm and 150 kN / mm with a material thickness in the range between 5 mm to 20 mm.
  • a cross section of a track section is shown, which - without limitation of the invention and purely by way of example - comprises a grooved rail 10, the foot 12 in the usual way on a rib plate 14 by means of z. B. clamps 16, 18 set is. Between the rail base 12 and the ribbed plate 14 itself, one can elastic plate 20 may be provided.
  • the rib plate 14 is in via bolts 22, 24 with a support, not shown Form z. B. connected to a threshold or concrete slab.
  • the bolt 22, 24 surrounded in the usual way by a sleeve 26, 28. In this respect, however, is sufficient known constructions.
  • an elastic intermediate layer runs between the rib plate 14 and the support 30 made of cellular elastomers such as polyurethane elastomer, which under the Designation Sylodyn® is offered.
  • This elastomer material has the property that its spring stiffness or characteristics change depending on the surface, is transmitted via the force or load transferred, that is, according to the prior art basically over the effective bottom surface of the rib plate 14.
  • Cutout 34 is provided in the longitudinal direction of the rail section extending strip-shaped sections 36, 38 is limited by those in the direction the support of perpendicular projections of the longitudinal edges 40, 42 of the rail foot 12 can be cut.
  • the strip-shaped sections 36, 38 are followed by further U-shaped sections Cutouts 44, 46, which extend around the connecting elements such as bolts 22, 24. Furthermore, the intermediate plate 32 has a peripheral edge 48
  • the intermediate plate 32 can preferably be made of sheet metal material, but also of hard material Plastic.
  • the intermediate plate 32 should have a thickness of 2 to 5 mm.
  • the areal extent, that is to say the effective area over which the load is transmitted from the ribbed plate 14 to the elastic intermediate layer 30, should be 400 cm 2 .
  • a corresponding area extension covers the ribbed plates with floor areas in the range between 400 and 1,400 cm 2 .
  • the intermediate plate material should itself have a spring stiffness of more than 100 kN / mm.
  • the thickness of the intermediate plate 32 can be 2 to 5 mm.
  • the preferred areal extension of the intermediate plate 32 is then 400 cm 2 .
