FLOOR STRUCTURE OF BUILDING COMPRISING DYNAMIC VIBRATION ABSORBER
To provide a floor structure of a building comprising a dynamic vibration absorber which has preferable workability and whose performance hardly decrease.SOLUTION: A floor structure 1 comprises: a floor slab 2 having a void 11; a void formwork material 5 for forming the void 11; and a dynamic vibration absorber 3 disposed in an in-formwork hollow portion 14 formed inside the void formwork material 5. The dynamic vibration absorber 3 includes: a spring member 28 composed of foaming plastic having elasticity; and a weight 29 supported by the spring member 28 only from below so as to vertically vibrate. Since the dynamic vibration absorber 3 is disposed inside the void formwork material 5, after installing the void formwork material 5, the floor structure 1 can be constructed by the same procedure as a conventional one. The spring member 28 is supported not from above but only from below by the weight 29, so an influence of thickness change of the floor slab is small, and a problem of contact failure of an upper spring with the weight due to long-term creep of a lower side spring does not occur.SELECTED DRAWING: Figure 1
【課題】施工性がよく、かつ性能が低下し難い動吸振器を備える建物の床構造を提供する。【解決手段】床構造１は、ボイド１１を有する床スラブ２と、ボイド１１を形成するためのボイド型枠材５と、ボイド型枠材５の内部に形成された型枠内中空部１４に配置された動吸振器３とを備える。動吸振器３は、弾性を有する発泡プラスチックからなるばね部材２８と、上下振動可能にばね部材２９に下方からのみ支持された錘２９とを含む。動吸振器３は、ボイド型枠材５の内部に配置されるため、ボイド型枠材５の設置後は、従来と同様の施工手順で床構造１を構築できる。ばね部材２９は、下方からのみ錘２９が支持するものであって、上方から支持するものでないため、床スラブの厚さの変更による影響が小さく、また、下側のばねの長期的なクリープによって上側のばねの錘との接触不良の問題が生じない。【選択図】図１
