Definitions
- the invention relates to a solid roadway embedded in a potting material Thresholds, especially two-block concrete sleepers, as well as elastic superimposed sound absorber elements, the elastic damping pads are designed for the sound absorber elements so that the sound absorber elements are held immovable across the road.
- the elastic support of the sound absorber elements is independent whether the support as an elastic damping plate or as an elastic Adhesive layer is the difficulty caused by the high stress shaking movements occur when driving over the rails, which too a lateral displacement of the sound absorber elements. But this can also not be turned off simply by placing them between the rail heads rigidly attached, since then the damping effect is impaired.
- On lateral migration of the sound absorber elements is particularly disadvantageous, on the one hand because of the risk of one-sided application to the sleeper heads with the difficulties already mentioned regarding damping and in particular because of the lateral displacement caused thereby Line conductors, as they are often between the rails on the damping elements for train control / train control. Here it comes insist that these line conductors are positioned exactly in the middle between the rails and are not damaged by moving absorber elements allowed to.
- the invention is therefore based on the object of a fixed carriageway at the outset mentioned type so that even taking tolerances into account due to the dimensions of the absorber plates Road vibrations are excluded and at the same time an optimal one Drainage of the absorber is possible.
- the invention provides that the between the sound absorber elements arranged on the rails on elastic damping strips rest with the lips upright centering between the sound absorber plates and engage the threshold heads.
- damping strips could also be U-shaped to the To completely grasp the central sound absorber elements at the bottom, it has in the Practice proven to be particularly useful, the arranged between the rails Sound absorber elements at the ends on two separate, essentially L-shaped ones To store damping strips.
- the fixed roadway shown in Figures 1 and 2 comprises a hydraulically bound Base layer 1, on which a concrete trough 2 is applied, in which a Rail grating made of two-block concrete sleepers 3 with rails connected to them 4 and 5 after appropriate alignment, for example via track regulation portals, embedded in a potting material 6, for example concrete or asphalt is.
- the thresholds 3 so-called two-block sleepers, the rail supports supporting the rails are formed on individual blocks 7 and 8 by the continuous Reinforcement 9 are interconnected.
- On the solid road are inner ones Sound absorber elements 10 and outer sound absorber elements 11, which on the one hand consist of a corresponding sound-absorbing material and on the other hand with a profiled surface, which has an additional Soundproofing causes.
- inner sound absorber elements 10 can be seen a line conductor 14 for train control.
- the outer sound absorber elements 11 are supported on damping strips 15, these damping strips also optionally on the underside the sound absorber elements 11 can be glued.
- the inner ones Sound absorber elements 10 are supported at each end on two separate ones Essentially L-shaped damping strips 16, which have a raised lip 17 have in the space between the upstanding heads of the concrete blocks 8 and 9 and the opposing end faces 18 of the sound absorber elements 10 intervene. This design prevents the sound absorber elements from migrating sideways due to the vibrations of the solid road when driving over it by a train and thus a shift of the line conductor 14 from the central axis prevented between the rails 5.
- the invention is not restricted to the exemplary embodiment shown. So could of course the support according to the invention also with solid Roadways are used where there is no separate trough for receiving the threshold gratings are provided, but the aligned track gratings immediately embedded on the hydraulically bound base layer 1 by means of potting material are. In addition, the broader footsteps could also be almost wide the entire sound absorber elements 10 form sub-panels, wherein it in In this case, however, it would be sufficient to have individual lips raised. So there is no need for a continuous, raised rib.
