摘要： PROBLEM TO BE SOLVED: To provide a soundproof structure of a rail, which can enhance a soundproof effect by reducing not only vibrations of the rail but also noises from the rail.
SOLUTION: The covering member 8 is detachably attached to the top surface and undersurface of a bottom section R
2 of the rail, and detachably attached to both side surfaces of a belly section R
3 of the rail. In the covering member 8, a sound absorbing layer 9a for absorbing the noises from the rail R is provided inside, and a vibration control layer 10a for suppressing the vibrations generated on the rail R is provided outside. When the layer 9a is formed of a viscoelastic body, it constitutes a flexible spring and an attenuator (dash pot), makes the vibrations from the rail R hardly propagate from the layer 9a to the layer 10a, and converts a part of vibrational energy of the rail R into thermal energy by making viscosity bring about vibration damping, so as to absorb and damp the vibrations. Consequently, the noises, which are emitted outward from the layer 10a, are reduced.

摘要翻译：要解决的问题：提供轨道的隔音结构，其可以通过减少轨道的振动而且减少轨道的噪声来增强隔音效果。解决方案：覆盖构件8可拆卸地附接到轨道的底部区段R 2 的顶表面和下表面，并且可拆卸地附接到腹部区段R SB的两个侧表面上， 3 的轨道。在覆盖部件8中，设置有用于从轨道R吸收噪声的吸音层9a，并且设置用于抑制在轨道R上产生的振动的振动控制层10a。当层9a由粘弹性体形成时，它构成柔性弹簧和衰减器（破折号），使得来自导轨R的振动几乎不会从层9a传播到层10a，并将一部分振动能轨道R通过使粘度产生振动阻尼而进入热能，从而吸收和减弱振动。因此，从层10a向外发射的噪声减小。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a soundproof structure of a rail, which enables a covering material to be firmly fixed to the rail, which facilitates manufacturing and construction, and which can enhance a soundproof effect.
SOLUTION: A right-side covering member 8a is mounted on the right-side lateral surface of the rail R, and a left-side covering member 8b is mounted on the left-side lateral surface of the rail R. After that, a right-side holding member 11a is mounted on the member 8a at a predetermined interval in the longitudinal direction of the rail R, and a left-side holding member 11b is mounted on the member 8b. Subsequently, a bolt 11h is inserted into through-holes 11f and 11g, and a nut 11i is attached to the bolt 11h, so that the members 11a and 11b can be connected together. Thus, even if increasing in thickness and weight, the covering member 8 can be firmly fixed to the rail R by means of a fixing member 11. Consequently, since vibrations generated on the rail R are reduced and acoustic radiation from the rail R is suppressed, a soundproof and vibration-control effect can be enhanced.
