FIELD: construction. ^ SUBSTANCE: prefabricated reinforced concrete surface of tracks comprises track rail-to-rail, track-to-track and side reinforced concrete boars laid in a butt joint, and according rubber fixators laid between boards and between rail of track and boards. At the same time end surfaces of according boards facing each other comprises a longitudinal ledge and an appropriate groove, and the specified fixators laid between the rail of track and according boards, are arranged in the form of a bar and have curvilinear surface at one side, and flat support surface at the other side for the appropriate board, and a ledge with the cavity in the form of a longitudinal channel to rest the side surface of the appropriate board. At the same time the specified longitudinal ledge and the groove of the specified boards are arranged in the form of a semicircle, the specified curvilinear surface of the specified fixators is arranged in the form of a surface that follows surfaces of a foot, journal, hard of the track rail and area of transition of track rail foot surface to surface of track rail journal, accordingly. At the same time in the area of transition of the track rail journal surface to the surface of the track rail head there is a groove arranged along the whole length of the bar. ^ EFFECT: improved operational characteristics. ^ 3 cl, 1 tbl, 12 dwg |
