FIELD: construction.
SUBSTANCE: invention relates to construction of railways, to design of intermediate bolt fastening of rails to rail lining. Inter-boltless fastener consists of rail, rail pad, two clamping plates, two rivets, leaf spring, support sheet, two-stage axis. At assembly, between rail sole and upper plane of leaf spring middle part there is a gap. Table rail, matrices, top and bottom hydraulic cylinders are to be installed at section for assembly of rail with rail pads. When assembling by upper puncheons of hydraulic cylinders, clamping plates with rivets are pressed to upper surface of flanges of rail pad. During clamping by upper punches of hydraulic cylinders, lower punches of hydraulic cylinders perform riveting, thus deforming leaf spring. Rail and rail lining form intermediate bolt-free fastening, which creates necessary and constant mounting tension of rail fastening assembly.
EFFECT: higher reliability of attachment, simplified current track content.
