Description of the Related Art Conventionally, an elastic material (bottom surface pad) is integrally provided on the bottom surface of a vibration-proof sleeper (not shown) to absorb vibration generated when a vehicle passes by and reduce noise. This elastic material is integrally provided with an adhesive and bolts and nuts. If the sleeper is made of concrete, put the manufactured sleeper in a formwork larger than the sleeper to create a gap between the sleeper and the formwork, and use urethane resin, which is an elastic body, in this gap. By injecting and solidifying, the elastic body is integrally provided on the sleeper.

らぎ受の立上り壁との間に側面用パッドを挿入する。In the factory, the sleeper anti-vibration device is attached to the sleeper in advance and transported to the rail track laying site, and the sleeper receiving portion is embedded in the roadbed. To attach the anti-vibration device to the sleeper, first lay the bottom pad on the bottom plate of the sleeper receiver. After that, the sleeper receivers are attached to both ends of the sleeper, and the side pad is inserted between the longitudinal side surface of the sleeper and the rising wall of the sleeper receiver.

Even if the gap between the sleepers and the rising wall of the sleeper receiver differs for each sleeper due to the dimensional tolerance or error in the width direction of the sleepers,
Since the cross-sectional shape of the side pad in the thickness direction is formed in a wedge shape, the side pad is inserted while absorbing dimensional tolerance or error.

The sleepers are attached to both ends of the sleepers and transported to the railway track laying site, where the sleeper receiving portions are embedded in the roadbed. When the rail stretches and deforms upward in the long rail section as the temperature rises, the sleeper is pulled up from the bed by the rail and tries to move upward. However, the side pad cannot move upward due to the friction between the side pad and the sleeper receiver.

To replace the sleepers, the side pads are removed, then the sleepers are lifted, and the sleepers are removed from the sleepers. The replacement of the bottom pad is carried out after the side pad is removed and then the sleeper is lifted to form a gap required for the replacement between the bottom surface of the sleeper and the sleeper receiver.

When the width of the sleeper C is narrow, the side pad 23 is inserted below the sleeper receiver 22 as shown in FIG. 15, and when the width of the sleeper C is wide, as shown in FIG. Is inserted above. That is, the side surface pad 23 absorbs the dimensional tolerance or error in the width direction of the sleeper C at the wedge-shaped portion.

上方への移動が阻止される。When the rail extends and deforms upward in the long rail section as the temperature rises, the sleeper C is pulled up from the track bed A by the rail and tries to move upward. That is, the sleeper C tries to rise from the track bed A. However, the side pads 23 are the side pads 2
The upward movement is blocked by the friction between 3 and the slope 37 of the sleeper receiver 22.

くらぎの浮上がりが阻止される。The anti-vibration device for sleepers according to the present invention has the following effects. (1) Since the sleepers are configured to receive the sleepers without using adhesives, bolts and nuts, the sleepers can be simplified in shape. (2) By removing the side pad 23 from between the sleeper and the sleeper receiver, the bottom pad and sleeper can be replaced easily and quickly. (3) Since the pads for the bottom surface and the pads for the side surfaces have elasticity, it is possible to absorb vibrations when the vehicle passes and reduce noise. (4) Since the cross-sectional shape of the side surface pad in the thickness direction is formed in a wedge shape, the sleeper can be held by absorbing the dimensional tolerance and manufacturing error of the sleeper. (5) Since the side pad is inserted between the sleeper and the sleeper receiver, intrusion of dust into the sleeper receiver is prevented, and elastic deterioration of the bottom pad can be prevented. (6) When the sleepers are pulled up from the roadbed and try to float as the rails expand due to the rise in temperature, the side pads rise together with the sleepers due to the friction between the side pads and the sleeper receiver. Since the sleeper is received without doing so, the sleeper can be prevented from rising. (7) If the side pad rises integrally with the sleeper against the above friction, the engagement of the ridge and the groove prevents the sleeper from rising.
