FIELD: railroad track structure, particular, designs of fish plates for rail shockless detachable butt-joint which are installed inside track for interaction of their upper surface with wheel flange. SUBSTANCE: novelty in the design of fish plate consists in change of its upper surface in zone of joint by introduction in the middle part of boss forming projection whose upper part is curved and convex in longitudinal vertical plane, and conjugated surfaces of fish plate correspond to the internal surfaces of head and foot of joined rails. Application of the offered fish plate allows cutting down the expenditures for its manufacture due to simplified design, besides, in shockless rail butt-joint only one special fish plate is offered, the other members are of standard design that does not impair rail suspended butt-joint. EFFECT: simplified design of fish plate and preservation of suspended rail butt-joint. 6 dwg |
