【発明の名称】構造物の制振装置
Document Type and Number:
Japanese Patent JP2927573
Kind Code:
B2
Abstract:
A weight is disposed in an arbitrary story of a structure so as to be movable relative to a direction of motion of the structure. Rotary members are supported in the weight. Rigid members meshing with gears provided on each rotary member are slidably fitted in the weight. These rigid members are respectively coupled to a ceiling and a floor via coupling members. The rotary members and the rigid members are disposed on the weight in correspondence with two horizontal directions. As a result, a horizontal motion of the floor of the structure is temporarily converted into a rotational motion by the rotary members, and is then converted into a horizontal motion so as to be transmitted to the ceiling. At this time, since the rotary members are pivotally supported in the weight, the weight can be moved in the opposite direction to that of the floor without undergoing an arcuate motion, thereby exhibiting the effect of reducing an input of vibration.
