構造物用制振装置
Document Type and Number:
Japanese Patent JP6991422
Kind Code:
B2
Abstract:
To provide a vibration damping device for a structure in which the relative displacement is suppressed on the occurrence of vibration and the device natural period adjustment is diversified, and the device is miniaturized and the cost is reduced.SOLUTION: A vibration damping device for a structure of the present invention is configured by having: a base frame 2 installed in an object location; an air floating mass 6 arranged on the base frame and blowing out the air; a TMD mass 7 arranged on the upper part of the base frame, and floating by the air pressure from the air floating mass; a pair of guide rails 10 arranged along the X direction, respectively, at both sides in the X direction of the base frame; the required number of sliders 11 slidably arranged in the X direction to the pair of guide rails, connected with each side face in the X direction of the TMD mass, and including a slider lifting/lowering mechanism 11A for lowering the slider 25 in the floating of the TMD mass; an oil damper 15 mounted in the X direction arrangement to the base frame, and exerting a damping action to the TMD mass; and a coil spring 16 mounted in the X direction arrangement to the base frame, and exerting a restoring action to the TMD mass.SELECTED DRAWING: Figure 1
