DAMPER MOUNTING STRUCTURE
To provide a damper mounting structure that can widely cope with small to medium earthquakes with small amount of horizontal shaking to long-period large earthquakes with large amount of horizontal shaking by using a damper of simple structure.SOLUTION: A damper 1 is placed vertically between a lower surface 4 and an installation surface 5 of a building, and its upper and lower ends are pinned together by clevis joints 2a, 2b so that they can be freely inclined with respect to the lower surface 4 and installation surface 5 of the building, respectively. A through hole 21 is provided in a base plate 20b of the clevis joint 2b, and a bolt 3b with a smaller shaft diameter than the through hole 21 is used to fix the clevis joint 2b to the installation surface 5, so that the clevis joint 2b can be moved horizontally relative to the installation surface 5 by the difference between a bore diameter of the through hole 21 and a shaft diameter of the bolt 3b.SELECTED DRAWING: Figure 1
【課題】単純な構造のダンパを用いて、横揺れ量の小さい中小地震から横揺れ量の大きい長周期大地震まで広く対応可能なダンパの取付構造を提供する。【解決手段】ダンパ１を建築物の下面４と設置面５との間に垂直に配置して、その上端部および下端部をそれぞれ建築物の下面４および設置面５に対して傾斜自在となるようにクレビスジョイント２ａ、２ｂによりピン接合する。また、クレビスジョイント２ｂのベース板２０ｂに貫通孔２１を設け、貫通孔２１より小さな軸径のボルト３ｂでクレビスジョイント２ｂを設置面５に固定することにより、クレビスジョイント２ｂを、貫通孔２１の口径とボルト３ｂの軸径との差分だけ、設置面５に対して水平方向に移動可能とする。【選択図】図１
