Definitions
- the invention relates to a solid track with embedded in a potting material Sleepers, in particular bi-block concrete sleepers, as well as elastic superimposed sound absorber elements, wherein the elastic damping pads are designed for the sound absorber elements so that the sound absorber elements are held immovable transversely to the roadway.
- the sound absorber elements is independent of whether the Auflagerung as elastic damping plate or as elastic Adhesive layer is formed the difficulty that due to the high stresses When driving over the rails shaking movements occur, which too cause a lateral displacement of the sound absorber elements. But this one can also, not just be turned off by putting them between the railheads rigidly attached, because then the damping effect is impaired.
- One lateral migration of the sound absorber elements but is particularly disadvantageous First, because of the risk of one-sided application to the threshold heads with the already mentioned difficulties with respect to damping and in particular because of the resulting lateral displacement of any Line conductors, as they are often between the rails on the damping elements be moved to the train control / Switzerlandbeeinlung. Here it comes This is because these line conductors are located exactly in the middle between the rails and are not damaged by migrating absorber elements allowed to.
- the invention is therefore based on the object, a solid lane of the beginning type so that even under consideration of tolerances the dimensions of the absorber plates lateral displacements by Fahrbahner remplieronne are excluded and at the same time an optimal Drainage of the absorber is possible.
- the invention provides that the between The rails arranged on the sound absorber elements, in the rail longitudinal direction spaced, elastic damping strips rest, with the upstanding Lip centering between the sound absorber plates and the threshold heads intervention.
- damping strips could also be U-shaped to the completely surround the central sound absorber elements below, it has in the Practice proven particularly expedient, which is arranged between the rails Sound absorber elements end on each of two separate substantially L-shaped To accumulate damping strips.
- the fixed carriageway shown in Figures 1 and 2 comprises a hydraulically bound Supporting layer 1, on which a concrete trough 2 is applied, in which a Rail grid of two-block concrete sleepers 3 with rails connected to it 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 to so-called two-block sleepers whose rail supports the rail support are formed on individual blocks 7 and 8, passing through the Reinforcement 9 are interconnected.
- inner Sound absorber elements 10 and outer sound absorber elements 11 launched the on the one hand consist of a corresponding sound-absorbing material and secondly with a profiled surface, which adds an extra Sound damping causes.
- inner sound absorber elements 10 can be seen a line conductor 14th to the train control.
- the outer sound absorbing elements 11 are supported on damping strips 15, wherein these attenuation strips optionally in addition to the underside the sound absorber elements 11 may be glued.
- the inner ones Sound absorber elements 10 store at each end on each 2 separate in the Substantially L-shaped damping strip 16 which has a raised lip 17 which are 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.
- the training can be made this way be that the lip 17, as can be seen in particular from Fig. 3 can, tapered conically upwards. In this way can by appropriate Inflection of this lip an interception of manufacturing tolerances done.
- the support of the invention could also be fixed Roadways are used, where no separate trough for receiving the threshold grates is provided, but the aligned track grates immediately embedded on the hydraulically bound support layer 1 by means of potting material are.
- the foot strip could also be wider almost form the entire sound absorber elements 10 under cross plates, wherein it is in In this case, however, it would be sufficient to let individual lips stand up.
