方法が従来から採られている2. Description of the Related Art In a building such as a station building or a terminal building in which a vibration source such as a railroad track or an elevated road is pulled in, a solid vibration from the vibration source or a vibration sound accompanying it is generated. Various methods to block or reduce have been adopted conventionally

す振動を軽減する構成としたものである。As a conventional vibration isolation method in, for example, a station building, a method shown in FIG. 13 or 14 is known. Of these, the one shown in FIG.
By laying a vibration damping mat made of hard elastic rubber or the like or a cushioning material having a large vibration isolation effect such as a spring under the track 2 of the railway vehicle 1, the structure (floor) 4 of the building 3 is affected. It is configured to reduce vibration.

分な振動遮断効果を発揮させることができず、根本的解
決策とは言えない。However, the conventional vibration isolation method as described above has the following problems. First, in the method shown in FIG. 13, since the weight of the vibration source is considerably large including the vehicle, the rigidity of the vibration isolating cushioning material must be correspondingly increased. In order to give the cushioning function to the cushioning material, the structure must be contradictory, so that the sufficient vibration isolation effect cannot be exhibited, and it cannot be said to be a fundamental solution.

間の利用価値が落ちるという問題がある。On the other hand, in the method shown in FIG. 14, the frame having the floor slab 5 on which the track 2 is mounted and the pillar 6 supporting the floor slab 5 is an independent frame separate from the skeleton of the building. Therefore, the vibration isolation effect and the solid sound transmission sound isolation effect are effectively exhibited, and although this makes it possible to use the building with high added value, in the floor below the track,
In addition to the pillar 9 that supports the frame of the building, there is a pillar 6 that has an independent frame that supports the track 2. As a result, there is a problem that the utility value of the space is reduced.
