FIELD: rail vehicles; construction.

SUBSTANCE: invention relates to the field of railway and construction fasteners, namely to an anchor tire for embedding into reinforced concrete structures and an anchor set with its use. Structure of the anchor bar of the C-shaped cross section includes a U-shaped base containing a floor with at least one flexible support fixed in it as a rod of diameter d with thickening D on the end and two side walls, at the end of which there are ledges of a special shape. Ledges form slot S of width in lengthwise direction of anchor line. Between inner surface of side wall and projection there is an acute angle α = 50–70°, at the vertex of which there is a radius with an undercut, the distance L between the inner surfaces of the side walls is more or equal to 2 distances H from the inner surface of the floor to the inner edge of the protrusion, and the diameter of the thickening D is more than 1.5 times greater than the diameter of the rod d.
