VIBRATION CONTROL METHOD OF STEEL RUNNER AND VIBRATION CONTROL STRUCTURE
To suppress impact noise occurence from a steel runner without changing the structural requirement of a reinforced concrete building.SOLUTION: A vibration control method of a steel runner is used for a steel runner 14 with a U-shaped cross section, fixed to a concrete ceiling slab 12 and having two projections 16 and a connection part 18. The steel runner 14 is fixed at multiple fixing parts with intervals in the extending direction thereof, and upper ends of multiple studs 22 are fitted between the two projections 16. A vibration control member 24 having a thermal expansion coefficient smaller than that of the steel runner 14 is set at least at the vicinity of each of the multiple fixing parts in the space between the two projections 16 of the steel runner 14 in a closely attached state to at least both of the two projections 16. Thus, vibration of the two projections 16 is restricted, and impact noise occurence from the steel runner 14 can be suppressed.SELECTED DRAWING: Figure 1
【課題】鉄筋コンクリート造建物の構造的要件を変更することなく、鋼製ランナーからの衝撃音の発生を抑制する。【解決手段】鋼製ランナーの制振工法は、コンクリート製の天井スラブ１２に固定され、２つの突出部１６と接続部１８とを備える、断面がコの字状を成す鋼製ランナー１４を対象とするものである。鋼製ランナー１４は、その延在方向に間隔を空けた複数の固定箇所で固定され、２つの突出部１６の間に複数のスタッド２２の上端が嵌合される。このような鋼製ランナー１４の、２つの突出部１６間の隙間の、少なくとも複数の固定箇所の各々の近傍に、少なくとも２つの突出部１６の双方に密着させる態様で、鋼製ランナー１４よりも熱膨張率が小さい材質の制振部材２４を設置する。これにより、２つの突出部１６の振動が拘束されるため、鋼製ランナー１４からの衝撃音の発生を抑制することが可能となる。【選択図】図１
