Abstract
A composite railway sleeper (1; 50; 100) comprising an outer coating shell (2; 51; 101) made of composite plastic material and a shaped structural core (3; 52; 102), made of a material comprising at least concrete contained within said outer coating shell (2; 51; 510; 101), wherein said outer coating shell (2; 51; 510; 101) presents in the upper outer face (2a; 51a; 101a) two distinct and opposite groups of grooves (4; 53) suitable to receive the angular guide plates (G) belonging to pre-assembled elastic type fastening systems (64) for the connection of two respective rails (R) with said railway sleeper (1; 50; 100).
Claims17
A composite railway sleeper comprising:
- an outer coating shell made of composite plastic material;
- and
- a shaped structural core, made of a material comprising at least concrete contained within said outer coating shell,
- characterized in that said outer coating shell presents in the upper outer face two distinct and opposite groups of grooves suitable to receive the angular guide plates belonging to pre-assembled elastic type fastening systems for the connection of two respective rails with said railway sleeper.
The composite railway sleeper according to claim 14 characterized in that said distinct and opposite groups grooves are symmetrically arranged each other with respect to the transverse symmetry axis (Y) of said outer coating shell.
Railway track comprising:
- a pair of rails parallel and spaced apart each other by a prefixed gauge;
- a plurality of composite railway sleepers, arranged at least predominantly between said rails one consecutive and spaced apart each other in such a way as to define linear directions parallel each other and incident the direction defined by said rails and suitable to be placed superiorly close a foundation bed, each of said composite railway sleepers including:
- an outer coating shell made of composite plastic material;
- a shaped structural core, made of a material comprising at least concrete contained within said outer coating shell;
- pre-assembled elastic type fastening systems which connect each of said rails with said railway sleeper,
- characterized in that said outer coating shell presents in the upper outer face two distinct and opposite groups of grooves which receive the angular guide plates of said pre-assembled elastic type fastening systems.
