FIELD: construction, road engineering.SUBSTANCE: invention relates to fixing assembly for rails. Assembly of a railway sleeper and a rail platform for support of the rail comprises the railway sleeper, a pair of rail terminals support arms, concreted in situ in the sleeper, a pair of insulators of arms, each of which has a form for location on the rail surface of the rail arm, a pair of rail terminals, each having a section of a base made as capable of placement in the supporting arm of the rail terminals, and a thrust section made as capable of placement on the rail foot. The terminal and thrust insulators assembly is set on the arm in vertical direction so that parts of the thrust insulator are arranged in slots in the arm, and the possibility is provided to move the assembly of the terminal and insulator to the rail, but not from it. The base of the terminal is levelled with the slot of the arm and enters it, when the terminal moves to the initial position. The terminal may also move to the set position, in which thrust insulators are arranged on top of the rail foot and reliably retain it.EFFECT: insulators are not exposed to damage in process of assembly.2 cl, 15 dwg |
