Description

TECHNICAL FIELD

The technical solution relates to a sleeper, for the connection of rail fields, in the construction of rail tracks.

rail ends

BACKGROUND OF THE INVENTION

With the existing technology of rail track construction, rails are attached to sleepers. The ends of the rails in the track field extend over the last sleeper so that the contact of the two adjacent rails is outside the solid sleeper base. During the dynamic stress of this contact of the rails, caused by the travel of the wheelset of the railway vehicle, the rail substructure gradually breaks out and consequently the impacts and loosening of the joint occur.

PRINCIPLE OF THE TECHNICAL SOLUTION

These drawbacks are largely eliminated by a contact sleeper for connecting rail ends, the principle being that symmetrical to the longitudinal axis of the sleeper body, which is at least twice the width of a conventional sleeper, is provided with fastening means for retaining two pairs of base plates lying side by side along the axis of the rails while maintaining their track gauge.

The advantage of such a sleeper is that, under the dynamic stress of the rail connection carried by it, its substructure does not break out and thus the entire joint is released.

BRIEF DESCRIPTION OF THE DRAWINGS

An exemplary embodiment of a sleeper is shown in the accompanying drawing, wherein FIG. 1 shows a side view of a sleeper in contact with rails, and FIG. 2 shows a plan view of the contact of two track fields on a sleeper.

EXAMPLE OF CARRYING OUT THE TECHNICAL SOLUTION

The contact sleeper, while maintaining all other dimensions, exhibits at least twice the width _ s compared to the width of a classical sleeper. In its body, gripping means o, pro are provided symmetrically to its longitudinal axis 7

Two pairs of base plates 3 are placed side by side in the axis 4 of the rails 4, while maintaining the track gauge r. The contact of the two ends of the adjacent rails 4 is thus located between the two pairs of base plates 3. The feet

Thus, the rail 6 lies directly on the surface of the sleeper. The connection is carried out by means of conventional connecting means with shims 2.

This eliminates the possibility of unequal underbearing of the subsoil ends of the individual track fields and the occurrence of height differences between adjacent rail ends 4. Maximum movement of the two rail heads 4 can be even.

INDUSTRIAL APPLICABILITY

The contact sleeper can be used for the construction of new railway routes and for the repair of existing routes.
