Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration control device suitable for use in a base-isolated structure such as a business-isolated building, a base-isolated apartment house, a base-isolated detached house and the like.

[0002]

Various proposals have been made to make a seismic isolation structure by interposing a seismic isolation device between a structure such as a business building and the ground. In this case, in order to make the structure a seismic isolation structure, it is necessary to support the load of the structure and not to transmit the horizontal vibration of the ground to the building. In addition to the function of returning to the original structure after the vibration is attenuated, a function such as a return-to-origin characteristic is required.

[0003] A sliding bearing or a laminated rubber bearing in which a rubber layer and a steel plate are laminated is used to support the load of the building and prevent the horizontal vibration of the ground from being transmitted to the building. When a bearing is used, elastic means such as rubber is used in combination to supplement the home return function characteristic, and high damping rubber or the like is used for the rubber in order to supplement the vibration damping characteristic, or a steel rod or the like is used. When a laminated rubber bearing is used, in which the laminated rubber effectively supplements the return-to-origin function, in order to supplement its vibration damping characteristics, the same as the sliding bearing is used. High attenuation rubber is used for the rubber layer, or a steel rod or the like is separately installed.

[0004] A laminated rubber bearing having a columnar lead is known as preferably satisfying all of the above-mentioned required functions. In this laminated rubber bearing, the columnar lead effectively reduces the vibration damping characteristics. I am trying to make up for it. Therefore, the laminated rubber bearing provided with the columnar lead is particularly preferable in that the installation space and the number of installation steps can be reduced in that no other vibration damping means such as a steel rod is required.

By the way, in order to support the load of the structure, the above-mentioned sliding bearing, laminated rubber bearing or laminated rubber bearing having columnar lead is used, while the vibration damping function and the origin are required for the sliding bearing. In order to obtain a return function, for a laminated rubber bearing or a laminated rubber bearing with columnar lead, in order to obtain a further vibration damping function and an origin return function,
When one end face is fixed to a structure such as a business building and an intermediate part is used together with the above-mentioned bearing, a vibration damping device made of a rubber body or a laminated rubber connected to a support such as the ground supporting the structure is used. If the other end surface of the rubber body or the laminated rubber is not inclined with respect to the one end surface, it is difficult to obtain a desired vibration damping function and a home return function.

Further, in a laminated rubber bearing having columnar lead, the columnar lead is not pressed appropriately, in other words, the columnar lead is densely embedded in the laminated rubber, and the rubber member is used. If the pressure is not appropriately applied, the desired vibration damping function cannot be obtained. Therefore, the laminated rubber bearing having the columnar lead usually requires the pressurization of the columnar lead to reduce the load of the building. It is designed in consideration of the vertical pressure based on, but if it is to be performed by such a vibration damping device consisting of a rubber body having columnar lead, it is the same as a laminated rubber bearing with columnar lead In addition, a desired vibration damping function cannot be obtained unless the columnar lead is densely embedded in the rubber body and is not appropriately pressed by the rubber body.

Further, a laminated rubber bearing having columnar lead may be used in a vibration damping device in the same manner as described above instead of a rubber body or a laminated rubber mainly for the purpose of damping vibration. In this case, Since the load of the building is not applied to the laminated rubber bearing, a desired vibration damping function may not be obtained.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to fix one end face to one of a structure and a support for supporting the structure, In a vibration damping device having an elastic means whose intermediate portion is connected to one of the other of a structure and a support for supporting the structure, a desired vibration damping function and a home return function can be obtained. It is in.

Another object of the present invention is to provide a vibration damping device further comprising a lead means disposed in an elastic means so that the damping characteristics of the lead means can be exhibited effectively. It is in.

It is still another object of the present invention to provide a vibration damping device capable of effectively exhibiting a damping characteristic even when a conventional laminated rubber bearing having columnar lead is used as it is. Is to do.

When the ground 123 vibrates in the horizontal direction H due to the earthquake, some vibration in the horizontal direction H occurs in the building 105 supported on the foundation 122 via the seismic isolation device 121. This vibration causes the elastic members 55 and 56 of the vibration damping device 1 and the lead means 7 to be sheared in the horizontal direction H. The vibration energy of the building 105 is absorbed by these shearing deformations, especially the shearing deformation of the lead means 7, so that the vibration of the building 105 in the horizontal direction H due to the earthquake is attenuated as quickly as possible.

You can adjust the degree.

In the vibration damping device 1, since the movable direction of the elastic member 5 on the other end surface 4 side is guided and secured by the guide member 18, the other end surface 4 side of the elastic member 5 is more firmly not tilted. In addition, it is possible to avoid a situation in which the elastic means 5 and the like are distorted and expanded and contracted in the horizontal direction H, and the elastic means 5 and the lead means 7 are respectively elastic bodies 55 and 56 and a columnar lead. Due to the arrangement of 75 and 76, the mounting means 6 can be interposed between the pair, so that the connection to the elastic means 5 can be made easily and the connection can be made firm.

In addition, in the vibration damping device 1, a conventional laminated rubber bearing having columnar lead can be used as it is, so that the cost can be reduced and an optimal compressive force is applied to the lead means 7. In addition to the above, it is possible to appropriately set the optimal compressive force even after the installation, and to apply the compressive force to the lead means 7 through the elastic force applying means, so that the elastic means in the vertical direction V In addition to absorbing the temperature expansion and contraction of the elastic means 5 and the lead means 7, it is possible to prevent the elastic means 5 and the lead means 7 from being damaged.

The vibration damping device 1 may be interposed between the lower surface of the building 105 and the upper surface of the foundation 122 or may be directly interposed between the lower surface of the building 105 and the upper surface of the ground 123.
