Summary: | The utility model discloses a fastening systems for tram, wherein, screw spike pass plain washer, bullet strip, gauge apron with pre -buried in concrete sleeper buried sleeve be connected, screw spike compresses tightly the bullet strip at gauge apron and groove rail structural, the base keeps off the shoulder for the right angle, base bottom surface and concrete contact, gauge apron's the outside and the inboard in close contact with of base, gauge apron is close to the lateral surface and rail contact of rail side, installs the backing plate between rail bottom and the base. The beneficial effects are that: because the cover was intraductal during screw spike stretched into concrete sleeper, made things convenient for the later stage to lay and keeped in repair with the maintenance, gauge apron realizes great roll adjustment ability, and the non - rubber of backing plate part adopts the macromolecular material, causes that the fastener resistance is higher than the problem of ordinary fastener on the contra |
