备注：Remark:
1、除岔枕螺栓公差为±50N·m外，其他所有公差为±10%；
Tolerance of the sleeper bolfs torque is ±50N·m, tolerance of the others is ±10%
2、序号2弹条Skl12不需要控制扭矩，只要使弹条中环部分与轨底表面间距为即可，此时 其扭矩在180-200N·m范围；
There is no need to control the torque of the tension clamp (No.2 SKI12); just ensure that the gap between the clamp central part and the rail foot is of 0.1 mm-1 mm, and then the torque is 180-250N·m
3、序号4轨撑CStu7鱼尾板与轨腰连接的螺栓的紧固扭矩为1000N·m,与基板连接的T型螺栓的紧 固扭矩为250N·m；
NO.4 rail support (CStu7) fishplate and rail web connect bolt torque is 1000N·m, tightening torque of T bolt connecting with base plate is 250N·m
4、序号7叉心轨撑CStp 6螺栓或螺母，8.8级的为400N·m,其余的为250N·m；
NO.7 Rail support (CStp 6) bolt or nut: 8.8—400N·m, others: 250N·m
5、序号12顶铁螺栓或螺母有两种情况：螺杆和顶铁一体时，如顶铁CZS83,为650N·m；其余使用8.8级M27螺栓均为1000N·m；
NO.12 distance block bolts or nuts have two cases: when the bolt and distance block are together, e.g. distance block CZs83, the torque is 650N·m, the others M27-8.8 bolts5 torque is WOON·m
6、序号13 HRS锁闭装置螺栓或螺母有2种情况：双螺母安装，内侧薄螺母为120N·m,外侧螺母为 225N·m,单螺母安装为225N·m。
NO.13 HRS locking device bolts or nuts have two cases: when assembling two nuts, torque of inside nut is 120N·m, torque of outside nut is 225N·m, when assembling one nut, the torque is 225N·m
