SUBSTANCE: according to the first version of an anchor clip-bolt joint, a rail is fixed to a sleeper using an anchor made of the upper and lower parts. The lower part of the anchor is built into a reinforced concrete sleeper. In the upper part of the anchor there are anchor flanges, between which a pad is placed, which is arranged as solid with the anchor, onto which a rail is installed, as well as support pads for clips with legs of variable height. An insulating pad is placed between the pad and the foot of the rail. Clips with a longer leg rest against a support pad of an anchor, and with a shorter leg rest against an insulating angle, which is arranged between the anchor flange and the side face of the rail foot. According to the second version of the anchor clip-bolt joint, the specified pad is not available, everything else is performed in a similar manner.

EFFECT: simplified design, reduced number of parts required to do a joint, lower labour expenses in assembly of a rail and sleeper grid and routine maintenance of a track.
