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 with a spring stiffness, which is approximately depending on the area in relation to the respective effective support surface of the base plate changes to the intermediate layer, is arranged, the base plate with the support via a collar surrounded by a socket with a support on the support side Fastener is connected like a bolt.
  • a corresponding storage is to DE 44 06 105 A1 or EP 0 666 938 B1 remove.
  • the storage itself has a first and second elastic elements formed spring system with an overall characteristic curve that has a kinked course such shows that when the force applied to the spring system is less than that in Working area is force, the characteristic increases steeply and in the working area runs flat. This has the advantage that when driving through a corresponding one Track section vibrations are strongly damped, so that unwanted Vibration transmissions to the substructure are prevented.
  • 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.
  • the present invention is based on the problem of storing the previously further described type in such a way that regardless of the load, ie especially in the event of a rail break, the maximum deflection of the base is limited so that a tilting of the track section to an extent that leads to a Danger of a rail vehicle passing through the track could certainly lead is prevented.
  • the problem is essentially solved in that between the Base plate and the intermediate layer an intermediate plate removing the base plate is arranged, which has the support-side collar socket such surrounds that the intermediate plate with the usual application of force to the base plate spaced from the collar and in the event of impermissible force transmission on the Collar is on.
  • the storage according to the invention ensures that the base is dimensioned can deflect as much as possible, to the extent that the support side running intermediate layer is sunk in such a way that the intermediate plate is on block the circumferential collar of the socket rests with the result that further movement and thus no more lowering of the intermediate layer in the vertical direction can be done.
  • the extent to which the base plate is dimensioned is thus predefined the ribbed plate can sink under extreme loads, which in turn the tilting of the track section attached to the base plate is limited.
  • the base plate Since the intermediate layers made of cellular elastomers such as PU foams are used have a spring stiffness that is approximately linear depending on the contact surface the base plate is in a further preferred embodiment of the invention proposed that the intermediate plate a surface removing the base plate has, whose extension regardless of the intermediate plate facing load-bearing Bottom surface of the base plate is. It is therefore independent of the size the base plate can be given a desired spring stiffness that - up to the permissible Load - depends solely on the dimensioning of the intermediate plate, as this the sinking of the intermediate layer specifies. It is therefore particularly provided that at a bearing comprising several consecutive in the longitudinal direction of the track section Base plates with possibly different introduced Forces effectively absorbing floor areas regardless of floor area size between the respective base plate and assigned elastic intermediate layer intermediate plates are arranged in the same area.
  • the intermediate plate itself consists in particular of rigid plastic or metal such as Sheet.
  • the intermediate layer has a rigid insert made of metal or plastic, the thickness of which is the same or approximately is equal to the height of the collar of the bush plus the thickness of the intermediate plate. This further limits the depression of the rib plate, so that it is ensured that the track section starting from the base is not in to an unacceptable extent.
  • the intermediate layer is preferably a transverse to the longitudinal direction of the Track section extending strip-shaped plate, which is in particular along a Straight lines extending between the ribbed plate connecting to the support Fasteners such as bolts run. It can with usual load entry the insert runs at a distance from the support or rests directly on it. In particular, however, it is provided that the insert in the intermediate layer on the support side is uncovered by this.
  • intermediate plate in particular has a first cutout, below from which the insert runs. Thus extends directly above the insert only the intermediate layer and not the intermediate plate.
  • the intermediate plate is perpendicular to the support in the area running projection of the track section or its rail foot one has a further cutout in the area of the longitudinal edges of the rail foot and strip-shaped sections running in the longitudinal direction of the track section the intermediate plate is limited.
  • the rail experiences in the area of its longitudinal edges
  • targeted support such that tipping is limited.
  • the intermediate plate which can have a peripheral edge strip, can additionally with others in the area of the base plate connecting the support Connecting elements extending cutouts are provided on both sides outside vertical projection of the collar running perpendicular to the support run.
  • the intermediate plate is preferably both with respect to its longitudinal axis as well their transverse axis running parallel to the longitudinal direction of the rail section symmetrical, even if this is not a mandatory feature acts. Rather, an asymmetrical geometry can also be selected, in particular in the area of switches.
  • the intermediate plate itself preferably has a removal area of approximately 300 to 400 cm 2 , a thickness of in particular 2 to 5 mm being preferred when using sheet metal as the intermediate plate material.
  • the insert consisting of metal such as steel or hard plastic should in turn have a surface extension of preferably 50 to 100 cm 2 and / or a thickness of preferably approximately 5 to 15 mm, which, as mentioned, corresponds to the height of the circumferential collar.
  • 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 bearing for a track section is also included 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 is made of elastic material, the base plate with the support via at least one of a bushing with a collar on the support side
  • Surrounded fastener such as bolts is connected, proposed is characterized in that the base plate is the one running on the support side Collar-containing socket surrounds such that the base plate in the usual Force transmission at a distance from the collar and in the event of impermissible force transmission lies on the collar.
  • the collar can be adjusted if necessary have interchangeable attachment on which in the event of impermissible force application the intermediate plate or the base plate rests on the block.
  • FIG. 1 is a cross section of a first embodiment of a bearing 10 Track section shown, the - without limitation of the invention and only pure for example - a grooved rail 12, the foot 14 in the usual manner by means of z.
  • B. clamps 16, 18 with a base plate 20 in the form of a ribbed plate is set.

  • the rib plate 20 itself is with a support, not shown, in the form of, for. B. a threshold or concrete slab connected via bolts 24, 26, each from a bushing 28, 30 with a laterally projecting section on the support side as surrounding collar 32, 34 or collar are surrounded.
  • an elastic intermediate layer runs between the rib plate 20 and the support 36, in particular made of cellular elastomers such as polyurethane elastomer, which under the Designation Sylodyn® is distributed.
  • This elastomeric material has the characteristics that its spring stiffness or characteristic curve depends on the surface changes, via which the forces are transferred from the track, i.e. according to the state of the Technology basically via the effective bottom surface of the ribbed plate 20.
  • An intermediate plate 38 runs between the intermediate layer 36 and the rib plate 20, it is provided in particular that their extension is independent of that of the effective bottom surface of the fin plate 20. This ensures that the Force transmitted from the ribbed plate 20 to the elastic intermediate layer 36 regardless of the actual surface extension of the fin plate 20 always the same is large, so that for different rib plates the same elastic dimensions Intermediate layers 36 can be used.
  • the intermediate plate 38 has the additional task of realizing the invention Doctrine to meet, the depression of the liner 36 dimensioned too limit.
  • the intermediate plate 38 extends with sections 40, 42 above of the circumferential collar 32, 34, the intermediate plate 38 and thus its sections 40, 42 spaced apart from the usual force application in the support Collar 32 runs. This will lower the intermediate layer 36 in the usual way Force transmission not affected.
  • Above the collar 32, 34 means that vertical projection intersects the intermediate plate 38.
  • the top view of the intermediate plate 38 according to FIG. 2 illustrates, is in the direction the support of the perpendicular projection of the rail foot 14 is a rectangular one Cutout 44 is provided, the one extending in the longitudinal direction of the rail section strip-shaped sections 46, 48 is limited by those in the direction of the support perpendicular projections of the longitudinal edges 50, 52 of the rail foot 14 can be cut.
