In the figure, 6 is an upper friction plate made of a rubber-like material installed at the upper end of the spring device, and 7 is an upper friction plate made of a rubber-like material.
In the turbine building, 81 is a lower friction plate made of a rubber-like material installed at the lower end of the spring device, 9 is the joint surface with the upper friction plate of the Y' ring device, and 10 is the lower friction plate of the spring device. The joint surfaces 9 and 10 correspond to the upper friction plate 6 and the lower friction plate 8, respectively.

摩擦が生じ、地震エネルギーの吸収１行なう。In recent years, as the location of power generation flands and seismic regulations have become stricter, the design seismic motion has become larger than that of conventional plants, and as a result, the response of the slender turbine mount during an earthquake has increased. However, since the present invention has a friction surface having the above-described structure, in the event of an earthquake, the seismic force input from the turbine pedestal base 3 is not affected by the support structure of the turbine pedestal. through spring 4
゜5 Full deformation, and if the seismic force is within a certain limit, it completely absorbs the earthquake energy and completely prevents the transmission of the seismic force to the superstructure. In this case, the input seismic force causes friction at the joint surface 10 between the lower friction plate 8 and the lower part of the spring device, and between the joint surface 9 between the upper friction plate 6 and the upper part of the spring device, and the earthquake energy is absorbed.

生じる。The turbine mount having the vibration energy absorption mechanism 1 having the structure 2 described above can absorb the rotational vibration excitation energy of the turbine and turbine generator as high-speed rotating equipment arranged on the turbine mount. The spring device completely absorbs the vibrations, and at the same time, even when vibrations are applied from the turbine building foundation during an earthquake, the friction plates have a damping effect on the photographic displacement within a certain limit at the top of the turbine pedestal. Demonstrated and deformed during an earthquake? It can be suppressed. Therefore, regarding the cross-around pipes and the like that extend between the turbine mount and the turbine building, the horizontal movement of the upper part of the turbine mount is restrained, resulting in the effect that the relative displacement between the turbine mount and the turbine building is reduced.
