Definitions

• the invention relates to an elastic rail fastening, in which a ribbed plate is arranged above a supporting structure.
• Rail fasteners for slab tracks require due to the required height and 9.justieriana while elasticity under the vertical load technical equipment for transferring the cornering forces in the usually existing concrete rigid substructure.
• Known rail fasteners require a profiled substructure, e.g.
• Concrete sleepers with a shoulder construction designed for power dissipation are formed either in the form of beads or as vertical abutment on concrete sleepers or continuous concrete structures.
• the object of the invention is a not directly screwed, ribbed plates exhibiting elastic rail fastening system.
• the object is solved by the features specified in the characterizing part of claim 1.
• the rail fastening according to the invention is designed for side adjustments in both directions up to 15 mm and allows height adjustments up to 50 mm without a bending stress of the screw connection between the attachment and the rigid concrete base.
• the lateral forces are transmitted via an under the ribbed plate 9
• Elasticity one or more elastic intermediate plates 4 made of elastomer.
• the lateral adjustment of the rail fastening takes place during the initial installation by a geometrically arranged longitudinal groove 5 under the rail fastening. 1
• Longitudinal groove 5 is after surveying the determination of the position for the
• This elastic element 15 for holding down the adjusting plate 2 may e.g. be formed as an elastomeric molding.
• the Justierprofil 2 receives to secure its position in the installed state profiling in which the fastening screw 12 engages.
• Adjustment requirement of e.g. over 30 mm the adjustment profile 2 is replaced by an adjustment plate 14.
• the rail fastening 1 receives only one side of the ribbed plate 9 a stop bar 10. This ensures that the directed exclusively to the track outside
