FIELD: manufacturing technology.
SUBSTANCE: invention relates to a system of rail fastening. System of rail brace for elastic with force closure joint rail (2) with tie (1) track comprises at least one angular guide plate (5), fixed on the sleeper (1) by means of at least one screw (4), and at least one tension clamp (3). Radii of curvature of levers (3a, 3b) of the tightening clamp (3) are preferably in the range of 18-70 mm, wherein the ratio of adjacent radii of bend to each other inside every lever of tension clamp ≤1.9, the maximum radius of bending to the least ≤3.8, wherein the ratio of weight to angular width of the guide plate <1.3 g/mm is preferably approximately 1.25 g/mm.
EFFECT: system of rail brace with low weight is able to create high tension force.
