    • An assembly for fastening of railroad track incorporating a steel reinforced concrete tie with vertical thread steel sleeves welded to a reinforcement truss embedded in the concrete tie to which sleeves, track bolt assemblies may be threadably joined. A track bolt assembly includes a pair of hollow male threaded plugs, each threaded to a female thread in the opposed ends of a sleeve to retain a nut that is biased by a compression spring in the sleeve, to which nut, a track screw mounted to a hold-down block is engaged. With the hold-down block fixed against a track rail flange, the screw may be tightened in the nut of the sleeve to a pre-set tensile load as determined by the compression spring.
    • 一种用于固定铁路轨道的组件,其包括钢筋混凝土连接件,其中垂直螺纹钢套管焊接到嵌入混凝土连接件中的加强桁架上,套筒,履带螺栓组件可以螺纹连接。 轨道螺栓组件包括一对中空的公螺纹塞,每个螺纹塞在套筒的相对端部中的阴螺纹中,以保持由压缩弹簧偏压在套筒中的螺母,螺母被安装到 一个压紧块被接合。 当压紧块固定在轨道法兰上时,螺钉可以在套筒的螺母中被拧紧到由压缩弹簧确定的预设的拉伸载荷。
