- the trapezoidal part 141 extends with its Trapezteillteilserstreckung 154 from a first short side edge 55 to a second short side edge 156 of the alternative hard trapezoidal intermediate layer element 140 and thus also in the direction 147 of the longitudinal extent 148 of the alternative hard trapezoidal spacer element 140.
- the trapezoidal part 141 is also in this alternative embodiment of a plurality of transverse to its Trapezteillteilserstreckung 154 transverse rib elements 157 (numbered only as an example), which form a trapezoidal body 159 on the flat base body 158 of the alternative hard trapezoidal spacer element 140.
- the transverse rib elements 157 are arranged at a distance from one another in a row 160 next to each other, wherein the individual transverse rib elements 157 are additionally connected to each other by means of a central web part 170. As a result, the stability of the trapezoidal part 141 is significantly increased.
- the alternative hard trapezoid intermediate layer element 140 from FIGS. 3A to 3C is identical to the middle web part 170 with the hard trapezoidal intermediate layer element 40 shown in FIGS. 2A to 2D. In this respect, reference is also made to the description in this regard.
- the further possible hard trapezoidal intermediate layer element 240 shown in FIGS. 4A to 4D can, in addition to the single elastic intermediate layer element 1, also be the only further component of the intermediate structure 2 of the rail fastening system S shown by way of example in FIG. 6 for fastening the rail element 3 to the concrete threshold element 4 of the slab - Road 5 be.
- the further hard trapezoidal intermediate layer element 240 is substantially identical to the previously described hard trapezoidal intermediate layer elements 40 (FIGS. 2A to 2D) and 140 (FIGS. 3A to 3C). In this respect, reference will be made below only to the differently constructed trapezoidal part 241 and with respect to the remaining construction of the further hard trapezoidal Liner element 240 referred to the above description in order to avoid repetition.
- the trapezoidal part 241 of the further hard trapezoidal intermediate layer element 240 is characterized by a hollow body 275, wherein the hollow body 275 has a two-part cavity 276, which is spatially divided by a stabilizing transverse inner web 277. Due to the hollow body 275, the trapezoidal part 241 builds with less material and the other hard trapezoidal intermediate layer element 240 accordingly easily.
- the two hollow chambers 278 and 279 of the two-part cavity 276 are in this case conically formed by reinforced wall regions 280 (numbered only by way of example), so that the trapezoidal part 241 is very stable despite the hollow body 275.
- the first possible angled guide plate 90 shown in FIGS. 5A to 5D of the rail fastening system S shown by way of example (see FIG. 6) for fastening the rail element 3 to the concrete sill element 4 of the slab track 5 of a track bed (not shown) has two material recesses at a plate end 91 92 and 93, in which the described projecting tooth portions 25, 26 or 27, 28 and 49, 50 and 51, 52 or 149, 50 and 151, 152, respectively, to the corresponding components of the intermediate structure 2 with the respective angle guide plate 90 interlocking form-fitting particularly intimately with each other.
- the two material recesses 92 and 93 are in this case placed on a long side 94 of the angled guide plate 90 and also in the corners 95 and 96 of the long side 94, so that correspondingly complementary thereto formed cantilevered tooth parts 25, 26 and 27, 28 and 49, 50th or 51, 52 or 149, 150 or 151, 152 can fit accurately into the respective material recess 92 and 93, respectively.
- the angle guide plate 90 comprises a trapezoidal wedge element 97, by means of which it can engage in a further trapezoidal bead 98 (see FIG. 6) of the solid track 5.
- the rail fastening system S shown by way of example in FIG. 6 has the present advantageous intermediate construction 2, which is composed of a single trapezoidal part element of the invention comprising a trapezoidal part 341 comprising a trapezoidal intermediate layer element 340 according to the invention (see FIGS. 1 to 4).
- the hard trapezoidal spacer element 340 is fixed by means of its trapezoidal part 314 in the trapezoidal bead 42 of the concrete threshold element 4, as previously described in detail.
- this single elastic intermediate layer element 101 and this hard trapezoidal intermediate layer element 340 are interlocked with the angle guide plates 190 in the previously described manner (see FIG.
- Both the rail foot 9 and the respective angle guide plate 190 are in this case by means of a conventional tension clamp 1 1 (only exemplified numbered) compared to the concrete threshold element 4 clamped.
- the tension clamp 11 (numbered only by way of example) by means of a screw 13 (numbered only as an example) stretched, which is screwed in an introduced into the concrete threshold element 4 dowel 12 (only exemplified) with internal and external thread in a known manner.
