| 摘要 |
The invention relates to a sleeper ( 1 ) for a gravel-mounted structure in railways, which has a cross member ( 4 ) extending along a sleeper longitudinal axis ( 6 ) and two longitudinal members ( 5 ) spaced apart from one another by the cross member ( 4 ), and each longitudinal member ( 5 ) has a bearing ( 9 ) extending on a top face for mounting a rail element ( 10 ) above the longitudinal member ( 5 ). Each longitudinal member ( 5 ) has one or more mounting devices ( 26 ) for a rail fixing element ( 28 ) each for retaining a rail element ( 10 ) on the longitudinal member ( 5 ) and at least one of the mounting devices ( 6 ) is disposed transversely offset from the sleeper longitudinal axis ( 6 ) on at least one of the two longitudinal members ( 5 ). The invention further relates to a sleeper ( 1 ) of this type which is of a stepped or recessed design at the ends of the longitudinal members ( 5 ) , to enable connecting elements ( 56 ) to be fitted in these regions in order to secure two rail elements ( 10 ) lying end to end.
