As shown in the figure and FIG.
A liquid storage space 2a is formed to store liquid. Inside the liquid storage space 2a, a floating roof 5 formed in a disk shape floats on the stored liquid 3, and depending on the amount of the stored liquid 3, it moves up and down and in the directions of arrows A and B inside the tank body. It is movably mounted on the wall surface 2b, and the floating roof 5 is provided with a plurality of vibration damper devices 6 according to the present invention.

内にも、抵抗部材１１が水平方向に設置されている。As shown in FIGS. 1 and 2, each vibration damper device 6 is provided on the outer periphery of the floating roof 5 so as to face each other, and has an appropriate amount of liquid 8 such as water inside. ! It has a pair of liquid tanks 7.9 filled with the same amount of water, and the α-body tanks 7.9 are connected by a communication pipe 10. Inside the communication pipe 10,
A resistance member 11 such as a mesh is installed to partition the communication pipe 10 in the left and right direction in FIG.
Also inside, a resistance member 11 is installed horizontally.

。Since the liquid storage tank 1 has the above configuration,
When an earthquake or the like occurs, the liquid 3 stored in the tank body 2 causes sloshing and the floating roof 5 rolls in the directions of arrows C and D in FIG. Among the vibration damper devices 6 installed on the roof 5, some of the vibration damper devices 6 are different in height between the liquid tanks 7.9 in the directions of arrows A and B.

が可能となる。Now, suppose that the liquid tank 7 shown in FIG. 1 is higher than the liquid tank 9, and the liquid 8 in the liquid tank 7 is
0 into the lower liquid reservoir 9 on the opposite side. However, since the resistance member 11 is provided in the communication pipe 10 and the portion where the liquid 8 in each liquid $117.9 flows to prevent the flow of the liquid 3, The flow of liquid 8 that occurs in the storage R liquid 3 has a sloshing period and phase that are out of alignment, and as a result, the liquid 8 in the liquid tank 7.9 is rolling in the directions of arrows C and D of the floating house MI5. It works by suppressing vibrations. The vibration damper device 6 is a second
As shown in the figure, since they are provided around the entire circumference of the floating roof 5, no matter which direction the rolling vibration of the floating roof 5 occurs, any one of the vibration damper devices 6 can be used alone or in cooperation with each other. This makes it possible to effectively prevent shaking.

も当然可能である。In addition, although the case where the above-mentioned embodiment (the vibration control damper device 6) is applied to the α-body storage tank 1 has been described, the vibration damper device 6 is not limited to the liquid storage tank 1, but can also be applied in a vertical plane. Of course, it can be applied to any structure as long as the purpose is to prevent rolling vibration. For example, as shown in FIGS. 3 and 4, a vibration damper device 6 is installed on the bridge girder 12a of the suspension bridge 12, and liquid tanks 7.9 are installed on both sides of the bridge girder 12a in a filter shape, and the arrow C1 of the suspension bridge 12
Of course, it is also possible to configure the device to prevent rolling vibration in the D direction.
