Definitions

• the invention relates to a mounting for a track section with cross sections deviating from one another along the track section, in particular in the form of a switch, comprising a plurality of support points, each with a base plate such as a ribbed plate, tongue root plate, ribbed plate with sliding chair or with a support frame, and between the base plate and associated support such as an intermediate plate made of elastic material, such as a threshold or concrete slab.
• elastic intermediate plates are arranged between the base plates that receive the track, such as ribbed plates, and the support, such as sleepers or concrete plates, which is used both in ballast construction and on a solid carriageway.
• the elastic intermediate plates used can consist of cellular elastomers such as PU foams which have a spring stiffness which is approximately linearly dependent on the contact surface of the base plate.
• the support points running along a track, in particular in the area of a switch, have different stiffnesses, depending on whether they are at the start or end of the switch.
• the base plate like the rib plate of the base, is usually dimensioned such that a wheel load is passed through without deformation of the base plate.
• DE 198 23 812 AI shows a rail arrangement with an elastic intermediate plate, which consists of a one-piece vulcanizate and has an essentially flat upper surface and a zoned lower surface with different properties.
• DE 32 30 565 AI relates to a rail support for switch construction, which consists of blanks of individual plates connected by welding.
• the object of the present invention is to develop a bearing of the type mentioned at the outset for a track section with cross-sectionally differing rail sections, in particular in the form of a switch, in such a way that track-like conditions result, i.e. the bending line in the area of, for example, a switch or crossing of the in the normal track.
• each or essentially each support point of the track section has the same maximum depression, taking into account the rail section or sections removed from it.
• the intermediate plate on the resistance moment which is essentially determined by the rail section supported on the base plate or the rail sections supported thereon, is designed such that the same or substantially the same maximum depression for a wheel passing through the track section along the track section in each support point results.
• the respective intermediate plate has a surface extension which removes the base plate and which is independent of the load-bearing base surface of the base plate facing the intermediate plate.
• an elastic intermediate plate always has the same ablating surface underneath the base plate, regardless of its areal extent.
• the intermediate plate supports the base plate essentially in its front edge area with respect to the support.
• the intermediate plate itself should have bone-shaped recesses running along each longitudinal edge in the central region, which run at least symmetrically to the transverse axis, in particular also symmetrically to the longitudinal axis of the intermediate plate.
• the geometry of the cutouts is preferably selected such that each cutout has a length l a parallel to the transverse axis of the base and that two cutouts arranged in a row running parallel to the transverse axis have a distance l z with 1.1 xl a ⁇ l z ⁇ 1, Have 5 xl a .
• the cutouts are delimited by a continuous section of the intermediate plate, which, in the case of conventional, that is not impermissible, wheel loads with respect to the free outer surface of the sections of the intermediate plate which support the base plate and extend at the end edge, are set back. This ensures that in the event of impermissible load transfer, the base plate is also securely supported immediately below that of the base plate outgoing rail section takes place so that impermissible tensions are excluded.
• a U-shaped further recess is formed in the intermediate plate in the respective transverse edge region adjacent to the recesses having a bone-shaped geometry, the longitudinal legs of which have a maximum width which corresponds to the length of the respective recess on the edge side.

• FIG. 1 shows a fin plate 10 which is arranged, for example, at the start of a switch.
• a stock rail not shown, is fastened, which in turn runs between ribs 12, 14, 16, 18 and is held down by tension clamps, not shown.
• the ribbed plate 10 itself is connected to the support, such as a threshold or concrete plate, via screws 20 passing through openings 20, 22.
• the underside of the rib plate 10 is provided with an elastic intermediate plate 24.
• the intermediate plate 24 can completely surround the rib plate 10 both on the bottom and on the edge side, as the sectional representations of FIGS. 3-5 illustrate.
• the connection between the intermediate plate 24 and the rib plate 10 can be made by vulcanization.
• the rib plate 10 is supported via portions 26, 28 of the intermediate plate 24 on the end edge side. Between these existing Cut 32 runs with unloaded or usual wheel loads-bearing rib plate 10 spaced apart from the bearing surface 34 of the intermediate plate 24, which may correspond to the surface of a threshold or a concrete plate or with a plate directly supporting the intermediate plate 24. In this regard, however, reference is made to well-known constructions.
• Section 32 itself is composed of a central section 36 and sections 46, 48, 50, 52, 54, 56 which extend between recesses 38, 40, 42, 44 and which together form section 32. Furthermore, a further cutout 60, 62, which is rectangular in plan view, extends transversely to the longitudinal axis 58 of the intermediate plate 24 between the section 32 and the end edge regions 30, 28.
• the cutouts 38, 40, 42, 44 running in the longitudinal edge region have a bone shape and are arranged symmetrically both to the longitudinal axis 58 and to the transverse axis 64 of the intermediate plate 24.
• the cutouts 38, 40, 42, 44, 60, 62 result in a total support surface of the intermediate plate 24 and thus a rigidity such that the maximum depression of a support point specified by the rib plate 10 reaches a desired value, which is also achieved by other supports in the area the switch is specified as a parameter, regardless of whether the resistance or the moments of inertia of the rail sections supported on these deviate from the arrangement according to FIGS. 1-5.
• This is achieved in that when the section modulus of the superstructure is increased, the rigidity of the corresponding intermediate plate is correspondingly reduced by reducing the maximum supporting surface or by using another intermediate plate material having elasticity.
• the intermediate plate increases as the section modulus of the supporting rail section or sections increases is softer.
• a ribbed plate 66 with an integrated sliding chair 68 is shown, along the underside and the edge 70 of which an elastic intermediate plate 72 is arranged, which also supports the ribbed plate 66 essentially in the edge region when there is no or usual load, whereas Section 74 present in the center region runs at a distance from a base 76.
• the section 74 delimits - in accordance with the exemplary embodiment in FIGS . 1-5 - bone-shaped recesses 78, 80, 82, 84 which run symmetrically to the longitudinal axis 86 and the transverse axis 88 of the intermediate plate 72.
• U-shaped recesses 86, 88 are provided on the edge, which in the actual sense are composed of two U-shaped base sections 90, 92 and spaced apart from these L-shaped sections 94, 96, 98, 100, the legs of which run parallel to the transverse axis 88 104, 106, 108 and 110 have an extent which corresponds to that of the cutouts 78, 80, 82, 84 parallel to the transverse axis 88 of the intermediate plate 72.
• the cutouts 78, 80, 82, 84, 86, 88 are delimited by the section 74 of the intermediate plate 72, as is illustrated by a comparison of the top view of the intermediate plate 72 according to FIG. 7 with the sectional representations 8 and 9.
• the inner cutouts 78, 80, 82, 84 which run in the immediate vicinity of the transverse axis 88, have a bone shape.
• the sections of the intermediate plate 72 extending between the cutouts 78, 80, 82, 84 are circular in plan view. The same geometry applies with regard to the regions running between the L-shaped recesses 94, 96, 100, 102 and the adjacent recesses 78, 80, 82, 84.
• the recesses 78, 80, 82, 84 of bone-shaped geometry or the legs 104, 106, 108, 110 running parallel to the transverse axis 88 have a length l a which is smaller than the distance l z between the recesses 78, 82 or 80, 84. This one Distance l z is approximately 20-50% greater than the length of the recesses l a .
• the intermediate plate 72 Due to the greater moments of resistance of the rail sections supported on the ribbed plate 66 with sliding chair 68, i. H. Stock rail and tongue rail, in comparison to the section modulus of the stock rail fixed on the rib plate 10, the intermediate plate 72 has a lower rigidity than the intermediate plate 24 according to FIG. 2.
• FIGS. 10-13 A rib plate 112 with a support bracket 114 is shown, from which a wheel control arm extends.
• the rib plate 112 is arranged in the area of a frog.
• an elastic intermediate plate 116 extends along the underside of the rib plate 112 and surrounds the rib plate 114 at the edge (edge 118 of the intermediate plate 116 in FIG. 10).
• the intermediate plate 116 also has edge-side sections 118, 120, via which the rib plate 112 is usually removed.
• Bone-shaped recesses 122, 124 or U-shaped recesses 126, 128, 130, 132 are provided in the central region of the rib plate 112, the U-shaped recesses 126, 128 corresponding to the recesses 86, 88 according to FIG. 7.
• the geometry of the bone-shaped recesses 122, 124 corresponds to that of the exemplary embodiments explained above, with a symmetrical arrangement with respect to the longitudinal axis 134 of the intermediate plate 116.
• a section 136 of the intermediate plate 116 which, in the case of conventional wheel loads which act on the rib plate 112, is set back with respect to the edge-side sections 118, 120, such as the sectional views according to FIGS. 12 and 13 illustrate.
• the rigidity of the intermediate plate 116 is selected such that the maximum depression of a supporting element specified by the rib plate 112 point passing wheel corresponds to the support points comprising the rib plates 10 and 66.
