RAIL FASTENING ANCHOR Russian patent published in 2021 - IPC E01B9/30 E01B9/48 

FIELD: construction.

SUBSTANCE: invention relates to elements of rail track superstructure and is intended for attachment of rails to under-rail bases from reinforced concrete, polymer-concrete or composite materials, provided that under-rail bases are formed during manufacturing. Rail fastening anchor contains upper part, which includes two heads located above surface of under rail track on two sides from rail foot, each of which has to provide interaction of anchor with load control regulator of rail fastening connection two brackets with flanges for contact with insulating damping pad, as well as a lower part rigidly fixed in the under-rail base and combining heads of the upper part of the anchor by arch-type jumper with two shanks. Shanks in lower part of anchor are directed at an angle to vertical axis in range from 15 to 75° and have increased cross section at end sections. Geometry of all elements of lower part of anchor represents a set of transient curves of large radius, geometry of bridge corresponds to geometry of arch type structure.

EFFECT: result is higher strength, serviceability and durability of rail fastening anchor.
