BUCKLING PREVENTION MEMBER AND VIBRATION CONTROL DAMPER

PROBLEM TO BE SOLVED: To provide a vibration control damper that may be installed readily in a frame regardless of a size of a gap from a surface material, and has displacement at a time of excitation input efficiently into the vibration control damper while regulating out-of-plane deformation of the vibration control damper.SOLUTION: A buckling prevention member 30 is used with a vibration control damper 10 fitted in parallel with a frame surface of a frame of a wooden building, the buckling prevention member having a damper section 11 and an extention wooden material connected on an extended line of the damper section. The buckling prevention member includes an adhesion surface 33 adhered and fixed on the damper section 11, and a deformation regulating section (an elastic body 31) coming in contact with a surface material 7 with a flat plate 32 in between in the frame and fitted in a gap between the damper section 11 and the surface material 7, for regulating deformation in an out-of-plane direction of the vibration control damper 10.SELECTED DRAWING: Figure 2 【課題】面材との間の隙間の大きさにかかわらずフレーム内へ簡単に設置でき、制震ダンパーの面外変形を規制して加振時の変位を効率よく制震ダンパーへ入力させる。【解決手段】木造建築物のフレーム内に当該フレーム面と平行に取り付けられ、ダンパー部１１とその延長上に連結される延長木材とからなる制震ダンパー１０に用いられる座屈防止部材３０は、ダンパー部１１に接着固定される接着面３３と、フレーム内では平板３２を介して面材７に当接してダンパー部１１と面材７との隙間内に嵌まり込み、制震ダンパー１０の面外方向への変形を規制する変形規制部（弾性体３１）とを含んでなる。【選択図】図２
