摘要： PURPOSE:To reduce vibration and noise resulting from running trains and to increase safety of operation by prevention of widening of disorder in the rails, by fixing a vibration-proof trough made of an elastic member like urethane rubber or the like around a concrete sleeper to install in on ballast. CONSTITUTION:A vibration-proof device body 11 is formed by a flat part 13 contacting at the bottom of a concrete sleeper (a) and walls 15a, 15b contacting the front and rear faces 14a, 14b. Next, long grooves 16 are provided on the flat part 13 and through holes 17 for steel bars 20 are bored near the upper edge of both the walls 15a, 15b. Next, ballast around the existing sleepers (a) is improved and the vibration-proof device 11 is fitted at the bottom from the side of the sleeper (a) and further, both ends are fixed by reinforcing bolts 23 via washers 22 and L-shaped washers 26 respectively with the steel bars 20 in the middle. The ballast is returned and the work is completed. In this way, vibration and noise of sleepers (a) are reduced by the buffering effect of the elastic trough.

摘要： PROBLEM TO BE SOLVED: To prevent separation of laminated rubber, and to improve durability by including a diametrically different plural metallic cylinder bodies arranged in a concentrically circular shape and rubber loaded between the respective cylindrical bodies in the shape of connecting the mutual respective cylindrical bodies in the laminated rubber, and reducing tensile compressive stress to the rubber layer. SOLUTION: A conical rubber type axial spring of a laminated rubber structure includes diametrically different plural metallic cylindrical bodies 12a, 12b, 12c, 12d arranged in a concentrically circular shape and rubber 12e loaded between the respective cylindrical bodies in the shape of connecting the mutual respective cylindrical bodies, and is constituted so as to reduce tensile compressive stress to the rubber layer. That is, since a part corresponding to a metallic plate of the laminated rubber structure is wholly constituted of a first cylindrical body 12a to a fourth cylindrical body 12d, an adhesive state with the rubber 12e holds an excellent shape. Particularly, since the metallic plate between the rubber 12e wholly becomes the cylindrical body in this way, behavior of the cylindrical body itself is stabilized, and acts so that excess force is not applied between the rubber and the cylindrical body.

摘要： PROBLEM TO BE SOLVED: To prevent a track rubber pad from sticking to the rail, by forming a rubber pad sheet with rubber and a vulcanizing agent and a metal stabilizer to stabilize iron ion generated on the surface of the rail and forming a recess or a groove on the upper face of the track rubber pad getting into contact with the rail. SOLUTION: A track rubber pad 4 sheet is composed of rubber, a vulcanizing agent for the rubber, and a metal stabilizer to stabilize iron ion generated on the surface of the rail. A recess, a groove or a hole 8 is formed on the upper face of the track rubber pad 4 getting in contact with the rail. The contact area of the rail and the track rubber pad 4 becomes smaller because of the recess, groove, or hole 8. In this way, the track rubber pad is prevented from sticking to the rail and the pad can be easily removed and the safety of the work can be secured and further, damage to the pad on removing it is prevented and hence, it can be reused.
