Description

The utility model relates to the field of railway transport and, in particular, to the construction of reinforced concrete sleepers with fastening elements of security devices for the upper structure of the railway track with a ballast layer on bridges and tunnels.

In accordance with the current technical requirements, mandatory use is made on bridges and tunnels with a ballast layer of special security devices in the form of countersinks or counter rails fixed in the middle of the sleepers.

The attachment of countersaws or counter rails on wooden sleepers is carried out by driving crutches (see M.A. Frishman and others. The design of the railway track and its contents, M., "Transport", p.132-133).

A typical reinforced concrete sleeper is known, consisting of two symmetrically located under-rail parts with existing under-rail platforms and the middle part (see M.A. Frishman and others. Design of the railway track and its contents, M., "Transport", p. 74- 75).

The use of crutches for attaching countersaws or counter rails to reinforced concrete sleepers is excluded.

The objective of the proposed technical solution is to change the design of a typical reinforced concrete sleepers, which have a significantly longer service life than wooden sleepers, for the possibility of its use in transit on bridges and tunnels. The technical result is to ensure the stability of the attachment kontrugolov or counter rails.

The indicated technical result is achieved in the construction of reinforced concrete sleepers with fastening elements for security devices for bridges and tunnels with a ballast layer, consisting of two symmetrically located rail sections with rail tracks and a middle section, and next to each rail track on the inside of the rail track horizontal platform for the placement of security devices, while in the horizontal platform there is an element for fastening the security device beating.

The fastening element of the security device is a node of a typical rail fastening used for fastening the running rails to reinforced concrete sleepers.

The design of the mounting unit of the security device and the mounting unit of the running rails may be identical or different.

So, for example, on bridge sleepers with a fastening of type KB for fastening security devices, either a KB fastening unit with a bolt, a saddle-shaped washer and a plastic hollow core, or a screw fastening unit with a screw and a plastic dowel can be used.

For bridge sleepers with an anchor fastening like ARS for fastening security devices, either a KB fastening unit with a bolt, washer and hollow core can be used, as well as a screw-dowel fastening unit.

The drawing shows a reinforced concrete sleepers with fastening elements of security devices for bridges and tunnels according to the proposed utility model.

The drawing shows: 1 - reinforced concrete sleepers, 2 - rail track, 3 - horizontal platform for the placement of security devices, 4 - security device, 5 - security mounting element

devices, 6 - rail, 7 - the persistent edge of the rail track, 8 - the middle part of the sleepers.

The distance Δ (width of the gutter) from the side face of the running rail 6 to the working face of the guard 4 is constant throughout the laying of bridge or tunnel sleepers, with the exception of the extreme sections where the ends of the countersinks are brought together, forming the so-called “shuttle” and the width of the gutter accordingly increases .

Within the entire length of the guard at the sleepers located in its middle part, the distance t from the abutment edge 7 in the rail track of the sleepers 1 to the axis of the additional rail fastening unit is of constant value. For the sleepers located in the shuttles, the distance t takes different values, varying in steps to the middle of the sleepers.

Sleepers with a constant and variable value of t make up the set formed upon delivery of bridge or tunnel sleepers.
