Abstract (en)
[origin: EP2415933A1] An object of the invention is to provide a soundproof device preventing noise effectively by a single type of soundproof covers having the same length without necessity of preparation of a number of soundproof covers having different lengths. Three first to third rail ties S1 to S3 that fix a rail R are arranged in sequence from one end to the other end of the rail in the longitudinal direction. A first soundproof cover 31 is bridged between the first and second rail ties S1, S2, and a second soundproof cover 32 is bridged between the second and third rail ties S2, S3. The respective soundproof covers 31, 32 have a fixed length L which is longer than any of a pitch P1 of the first and second rail ties S1, S2 and a pitch P2 of the second and third rail ties S2, S3. Required portions of a rail surface is covered with the first soundproof cover 31 and the second soundproof cover 32 in a state in which opposed end portions of the first soundproof cover 31 and the second soundproof cover 32 are overlapped with each other over a predetermined width on the second rail tie S2.
