FIELD: railway building. SUBSTANCE: bolts 9 are anchored to sleepers 4 to press rail foot 2 isolated from the sleeper through isolating wedge clamps 8 of plastic, provided with holes for the bolts. Wedge clamps may be used to cover rail foot from top. A passage composed of two openings being oblique to each other is in the clamps. Wedge clamp provides fastener system on the sleeper to be preliminary installed, and allows one to realize such a gap between fastening members to install the rail on the sleeper without removing fastening members. Wedge clamp is made preferentially of cold- resistant, high-modular polyurethane and has members to support wedge clamp on the anchor in the sleeper. Finally, elasticity of the wedge clamp and/or dowel 5 and/or layer under rail foot may be fitted to one of other members. EFFECT: high efficiency in installation. |
