<P>PROBLEM TO BE SOLVED: To provide a vibration control metal fitting in which a viscoelastic body sheet is hardly released even if it is vibrated a plurality of times, and sufficient vibration control effects can be presented stably. <P>SOLUTION: Connection pieces 17 are mounted to a column or a beam by bolt-nut connection while being overlapped. Viscoelastic body sheets 39, 41 are held between a first mounting plate 3 and a second mounting plate 19 and between the second mounting plate 19 and a reinforcing plate 31 while being deposited, respectively. Therefore, in comparison with the case where the viscoelastic body sheets are not deposited, the viscoelastic body sheets are hardly released even if a great force is applied in a shear direction, and vibration control effects can be presented stably for a long term. <P>COPYRIGHT: (C)2013,JPO&INPIT |
