VIBRATION CONTROL MECHANISM AND CEILING STRUCTURE

Japanese Patent JP2018080804

A

PROBLEM TO BE SOLVED: To provide a vibration control mechanism etc. which achieves both earthquake resistance and vibration resistance.SOLUTION: A vibration control mechanism 30 has: an inner frame part 31; an outer frame part 32; a bolt 33; a rubber ring 34; a vibration control material 36; a vibration control pad 37; and sponge rubber 38 etc. In the vibration control mechanism 30, the inner frame part 31 and the outer frame part 32 are combined so as to relatively move in a vertical direction, and the bolt 33 penetrates through the inner frame part 31 to be fixed to the outer frame part 32. The vibration control material 36 is disposed on a horizontal plate 313 of the inner frame part 31. The bolt 33 is provided so as to penetrate through a hole 312a and a hole 313a of the horizontal plates 312, 313 of the inner frame part 31 and a through hole 363 etc. of the vibration control material 36 and both end parts of the bolt 33 are respectively fixed to an upper end part of the vibration control material 36 and a bottom plate 321 of the outer frame part 32.SELECTED DRAWING: Figure 3
