Claims

[Scope of utility model registration request]

A track bridge sleeper fastening fitting for fastening a track bridge sleeper to a bridge girder includes a hook bolt having a hook portion to the bridge girder at the lower part, and the hook bolt is provided with a neck portion having a rotation-preventing parallel surface under the threaded portion. and a detent fitting having a bolt through hole with a detent parallel surface, which is engaged with the detent parallel surface of the neck part in a state where the hook bolt is supported by riding on the bridge sleeper. and a bolt is introduced into the locking fitting for fitting the bolt through hole into the neck portion of the hook bolt from a side parallel to the locking parallel surfaces by engaging the mutual locking parallel surfaces. An opening is provided, and the locking metal fitting connects both locking portions with the locking portion of the locking metal fitting and a side surface of the bridge sleeper so that the locking metal fitting does not escape from the hook bolt through the bolt introduction opening. A nut for tightening the bridge sleeper is screwed into the threaded portion of the hook bolt through the locking fitting and the rotation preventing fitting. A track bridge sleeper fastening fitting characterized by:
