DEVICE FOR HIGHLY FLEXIBLE FASTENING OF PARTS ON STANDARD CONCERETE TIES Russian patent published in 2004 - IPC

FIELD: railway transport; permanent way.

SUBSTANCE: invention relates to fastening of rails on crushed stone base on rigid railway bed. Each rail is directed between two angular guide plates being pressed to concrete tie by clamp. Flexible intermediate plate is arranged between rail foot and tie. Angular guide plates are provided with first and second surfaces on end opposite to rail. First surface is tilted to vertical adjoining shaped inclined surface of tie, and second one directed vertically, projects beyond upper side of tie. Angular guide plate is provided with guide chute for inner arm of clamp. Plate distributing pressure is placed on flexible intermediate plate. Plastic lining is placed between pressure distributing plate and lower side of rail. Intermediate plate and pressure distributing plate adjoin, with geometric closing, longitudinal walls of intake space passing in longitudinal direction of tie. Attachment screws are secured in replaceable plastic threaded expansion bolts found in ties. Longitudinal axes of expansion bolts are tilted relative to vertical through angle of 5^o.

EFFECT: provision of high flexible sagging of rails.
