Definitions
- the invention relates to a solid track for rail vehicles, which has an inclined surface in the region of a curved course.
- a roadway slab is provided in fixed lanes, can be embedded in the thresholds.
- the roadway slab rests on a hydraulically bound base course, possibly also on an antifreeze layer, whereby the carriageway slab, the hydraulically bound support layer and the antifreeze layer are produced in separate operations.
- the engineering structures are often planned and executed in advance, regardless of the type of superstructure later carried out. In such cases, it happens that the surfaces of the engineering structures are not adapted to the fixed carriageway. In particular, there is usually no adaptation to the required elevation in the region of a curved course of the fixed carriageway, so that the fixed carriageway then has to be executed on a flat structure.
- Fig. 1 shows such a conventional structure of a fixed lane 1.
- the fixed lane 1 consists essentially of a carriageway panel 2, in which sleepers 3 are embedded parallel to the surface of the carriageway panel 2.
- the sleepers 3 are designed as bi-block sleepers with a lattice girder reinforcement 4.
- the deck plate 2 is located on a bridge and rests on a profiled concrete slab 5, which is concreted on an optional protective concrete slab 6.
- the bridge is given here merely as an example of a building with a horizontal surface.
- the profiled concrete slab 5 has an elevation and accordingly has a trapezoidal cross-section.
- the protective concrete board te 6 the profiled concrete slab 5 and the deck slab 2 made in separate operations, which is complicated and therefore expensive.
- the invention is therefore based on the problem of specifying a solid track for rail vehicles, which is simpler in construction and thus less expensive to produce.
- the fixed track according to the invention may have a grid-like reinforcement with longitudinal and / or transverse bars.
- This longitudinal and transverse reinforcement optionally forms, together with sleepers, preferably bi-block sleepers, a track grid, which is aligned prior to concreting and then cast with concrete.
- a plurality of vertically spaced-apart longitudinal and / or transverse bars are provided.
- several layers of longitudinal and / or transverse bars can be used according to the static requirements.
- the reinforcement of the carriageway slab of the fixed carriageway may comprise vertically arranged reinforcement sections, the length of which the respective height of the deck plate is adjusted.
- the reinforcement may have a plurality of transverse vertical bars arranged.
- sleepers may be embedded.
- the reinforcement of the deck plate is connected to a reinforcement of the sleepers, preferably on the elevated side of the deck slab.
- the reinforcement of the thresholds may be formed, for example, as a lattice girder, which is connected to the reinforcement of the carriageway plate by adjusting the track grating, for example by wire.
- the thresholds having the grid reinforcement are formed as single-block, two-block or multi-block sleepers.
- the deck plate with trapezoidal cross-section can be constructed on different types of substructure such as earthworks, bridges, tunnels or tunnels.
- the trapezoidal roadway plate can be constructed under a switch track.
- Fig. 1 shows a cross section of a fixed track according to the prior
- Fig. 3 shows a second embodiment of a solid according to the invention
- Fig. 2 shows a fixed track 7, which is located in the region of a curved course of the route.
- the fixed carriageway 7 comprises a carriageway plate 8, in which a two-block sleeper 9 is embedded.
- the two-block threshold 9 consists of blocks 10, 11, which are interconnected via a lattice girder 12. Of the Lattice girder 12 and the two-block threshold 9 are arranged parallel to the surface 13 of the carriageway plate 8.
- the roadway panel 8 has a flat underside 14, which is arranged in the illustrated embodiment on a protective concrete slab 15, but in principle on any surface of an engineering structure.
- the carriageway plate 8 with the carriage-bottom 14 and the inclined surface 13 has a trapezoidal cross-section.
- a grid consisting of longitudinal bars 16 and associated transverse bars 17.
- the transverse bars 17 adjoins the raised side of the carriageway plate 8 an angled, vertical reinforcement section 18, which in an approximately parallel to the surface thirteenth extending reinforcing section 19, which is connected to the lattice girder 12.
- the roadway plate 8 is concreted after the alignment of the track grate in a single operation.
- Fig. 3 shows a second embodiment of a fixed track according to the invention, wherein the same reference numerals as in Fig. 2 are used for matching components.
- the fixed track 20 shown in cross-section in FIG. 3 basically has the same structure as the fixed carriageway of FIG. 2. Because of the greater elevation, additional transverse rods 21 are provided as part of the reinforcement, which are located below the lattice girder 12 and above lower transverse rods 22. The transverse rods 21, 22 are arranged parallel to one another and to the underside 14. In addition to the outer vertical reinforcement section 18 further vertical, rod-shaped reinforcement sections 23 are arranged in the interior of the carriageway plate, whose length is adapted to the respective height of the carriageway plate.
- FIGS. 2 and 3 In the case of a curved course of a fixed track, the elevation changes only gradually, and accordingly the cross sections shown in FIGS. 2 and 3 are not to be considered as restrictions but as typical cross sections. stand, which merge into each other continuously. In the beginning and end of a curved course can be dispensed with additional cross bars 17, 21 and 22, instead, only the surface of the deck plate is slightly inclined.
