が可能となるからである。In such a conventional example, a sliding member 34 made of stainless steel or the like is generally provided with a sliding member 34 such as a fluororesin having a low coefficient of friction itself. It is often used as a sliding member. Because, in the above case, the upper structure A is mainly input as a horizontal load obtained by multiplying the loaded load of the upper structure A by the friction coefficient of the sliding member 34. By slidably interposing between the structure A and the lower structure B, the horizontal load input to the lower structure B at the time of the earthquake is greatly reduced and reduced by the sliding operation of the sliding member. This is because only the applied load can be input to the upper structure A.

ことはこれまで困難であった。However, even when a solid sliding member made of a fluororesin is employed, the coefficient of friction remains high as before (see FIG. 7), and even when a sliding member made of a fluororesin is used. It has been difficult to obtain a sufficient desired seismic isolation effect.

を十分回避し得ないという問題点があった。In addition, not only when a conventional solid sliding member made of fluororesin is used, the friction coefficient generally tends to greatly increase in accordance with a change in speed, and an earthquake having a large swing speed has occurred. In this case, the value obtained by multiplying the friction coefficient according to the speed by the load of the upper structure A is the horizontal force acting on the upper structure A. As a result, the horizontal force input to the upper structure A is There was a problem that the damage caused by the earthquake could not be sufficiently avoided.

Therefore, the friction coefficient generated on the sliding surfaces of the sliding members 3 and 4 is smaller than when the sliding member 4 made of fluororesin is directly in contact with the sliding member 3 made of metal. As a result, the seismic force (rolling) transmitted to the upper structure A is greatly reduced, so that the seismic isolation performance can be improved. In addition, it is not affected by the shaking speed of the earthquake, and can always exert a certain seismic isolation effect even for earthquakes of various vibrations.

が可能となるからである。In such a conventional example, a sliding member 34 made of stainless steel or the like is generally provided with a sliding member 34 such as a fluororesin having a low coefficient of friction itself. It is often used as a sliding member. Because, in the above case, the upper structure A is mainly input as a horizontal load obtained by multiplying the loaded load of the upper structure A by the friction coefficient of the sliding member 34. By slidably interposing between the structure A and the lower structure B, the horizontal load input to the lower structure B at the time of the earthquake is greatly reduced and reduced by the sliding operation of the sliding member. This is because only the applied load can be input to the upper structure A.

ことはこれまで困難であった。However, even when a solid sliding member made of a fluororesin is employed, the coefficient of friction remains high as before (see FIG. 7), and even when a sliding member made of a fluororesin is used. It has been difficult to obtain a sufficient desired seismic isolation effect.

In this case, the value obtained by multiplying the friction coefficient according to the speed by the load of the upper structure A is the horizontal force acting on the upper structure A. As a result, the horizontal force input to the upper structure A is There was a problem that the damage caused by the earthquake could not be sufficiently avoided.

Therefore, the friction coefficient generated on the sliding surfaces of the sliding members 3 and 4 is smaller than when the sliding member 4 made of fluororesin is directly in contact with the sliding member 3 made of metal. As a result, the seismic force (rolling) transmitted to the upper structure A is greatly reduced, so that the seismic isolation performance can be improved. In addition, it is not affected by the shaking speed of the earthquake, and can always exert a certain seismic isolation effect even for earthquakes of various vibrations.

Since the agent C is supplied as needed, a smooth state is always maintained and a stable low coefficient of friction can be achieved, so that a continuous lubricating effect is exhibited.

The seismic effect improves. In addition, the life of the sliding bearing 2 is extended, and the durability of the device is improved.
