WIND NOISE REDUCTION DEVICE FOR GRID-LIKE STRUCTURE, BALUSTER AND GRID-LIKE STRUCTURE
To provide a new wind noise reduction device for reducing wind noise of a grid-like structure, a baluster to which the wind noise reduction device is attached, and a grid-like structure provided with the baluster.SOLUTION: A wind noise reduction device 14 applied to a grid-like structure 10 having a plurality of hollow balusters 12 of rectangular cross section includes a pair of plate members 22 arranged inside the baluster and facing each other and extending in the extension direction of the baluster inside the baluster, and a plurality of spring members arranged between the two plate members at intervals in the longitudinal direction thereof and fixed to the two plate members to exert a pressing force on the two plate members so as to contact the inner wall surface of the baluster. The two plate members have a length dimension that allows them to contact the inner wall surface of the baluster at the peaks of amplitude in the vibrations produced when the grid-like structure receives the wind and the balusters vibrate in one or more of the primary, secondary and tertiary vibration modes.SELECTED DRAWING: Figure 2
【課題】格子状構造物の風騒音を低減するための新たな風騒音低減装置、風騒音低減装置が取り付けられた手摺子、及び手摺子を備える格子状構造物を提供すること。【解決手段】矩形断面の複数の中空の手摺子12を備える格子状構造物10に適用される風騒音低減装置14は、手摺子の内部に配置される互いに相対する一対の板部材であって手摺子の内部において手摺子の伸長方向へ伸びる一対の板部材22と、両板部材間にこれらの長さ方向に互いに間隔をおいて配置されまた両板部材に固定され両板部材に手摺子の内壁面に当接するように押圧力を及ぼす複数のばね部材とを備える。両板部材は、格子状構造物が風を受けて手摺子に１次振動モード、２次振動モード及び３次振動モードの振動のうちの１以上の振動モードの振動が生じたとき、生じた振動における振幅のピークの箇所において手摺子の内壁面に当接可能である長さ寸法を有する。【選択図】図２
