Claims (12)

1. Rail butt connection, including a beveled plane of the end of the rail, located at an indirect angle in plan to the longitudinal axis of the rail, characterized in that the specified beveled plane is located on the width of the skating strip along the rail head of the wheels of the rail transport.  2. The connection according to claim 1, characterized in that from the intersection of the beveled plane with the edges of the skating strip, the end of the rail to the sides in the plan is formed by spaced apart along the longitudinal axis of the rail protruding and lagging planes perpendicular to the specified axis.  3. The connection according to one of claims 1 and 2, characterized in that the end face of the lateral edge of the head adjacent to the lagging plane is formed by a beveled plane.  4. Connection according to one of claims 1 to 3, characterized in that the rails are laid in the rail track so that the extended bevel lines of the ends of the rails to the track axis form sharp angles with it, the vertices of which are directed towards the movement of the rail transport or the main transport on single track roads.  5. The connection according to one of claims 1 to 4, characterized in that the bevel angle of the end of the rail to the longitudinal axis of the rail is determined as arctg k / 4 / τ≤α≤arctg R / 2 / τ, deg, where k is the strip width rolling of the wheels of rail transport along the rail head in the initial period of its operation, for example, after the first grinding of the rail heads, mm, τ - the maximum gap between the ends of the rails along the axis of the rails, mm, permissible for a given region of the region. 6. The connection according to one of claims 1 to 5, characterized in that the distance between the protruding and lagging planes of the end of the rail along the longitudinal axis of the rail is determined depending
L = k _cp / tgα, mm,
where k _cf - the width of the skiing strip in the long term in the average period of operation of the rail, mm 7. The compound according to claim 6, characterized in that the rail length is determined depending
L = L1 + l, mm
where L1 is the normal length of a typical rail with straight cut ends, mm.  8. Connection according to any one of claims 1 to 7, characterized in that bushings are installed in the enlarged openings of the ends of the rails.  9. A connection according to any one of claims 1 to 8, characterized in that the ends of the rails of both rail threads are connected by a metal bond in the form, for example, of an armature with an earthing switch in the form of, for example, a section of a rail vertically mounted in the ground.  10. The connection according to claim 9, characterized in that the ground electrodes are installed between the paths.  11. The connection according to one of paragraphs.9 and 10, characterized in that from the ground electrode made metal connection with both rail threads of adjacent tracks.  12. The compound according to any one of paragraphs. 1 and 11, characterized in that between the longitudinal stiffeners of the rail butt pads in places, at least between their holes, transverse stiffeners are made.
