FRICTION-VIBRATION DAMPING DEVICE
PROBLEM TO BE SOLVED: To provide a friction-vibration damping device suited for wooden houses with a ventilated or sealed underfloor space, the device being of simple structure, low-cost and high in workability, and functioning effectively at times of medium-scale or large-scale earthquakes.SOLUTION: A friction-vibration damping device comprises a first slipping flat plate of a disc-shape in contact with a groundsill, a second slipping flat plate of a disc-shape in contact with a foundation, and a third slipping flat plate of a disc-shape inserted between the frist slipping flat plate and the second slipping flat plate. The thicknesses of the first slipping flat plate and the second slipping flat plate are about the same, while that of the third slipping flat plate is larger. An insertion hole is pierced through the plates at the center for loosely inserting an anchor bolt. The diameter of the first slipping flat plate is about the same with the width of the groundsill, and is larger than that of the second slipping flat plate and the third slipping flat plate. The diameters of the insertion hole of the first slipping flat plate, the third slipping flat plate and the second slipping flat plate become smaller, in that order. The overlapped surfaces between the plates are smooth and in contact with each other uniformly.
【課題】床下空間が換気型や密閉型等の木造住宅に対応でき、簡単な構造を有し低コストで施工性にも優れ、中規模や大規模地震に有効に機能する摩擦減震装置を提供する。【解決手段】土台に接触する円盤状の第１の滑り平板と、基礎に接触する円盤状の第２の滑り平板と、該第１の滑り平板および該第２の滑り平板に介挿される円盤状の第３の滑り平板とからなり、前記第１の滑り平板および前記第２の滑り平板の厚さは略同一であり、前記第３の滑り平板はそれより厚く形成され、その中心部にはアンカーボルトが遊貫する挿通孔が貫設され、該第１の滑り平板の直径は前記土台の幅と略同一であって該第２の滑り平板や該第３の滑り平板よりも大きく形成されるとともに、該第１の滑り平板の挿通孔の直径、該第３の滑り平板の挿通孔の直径および該第２の滑り平板の挿通孔の直径はこの順に小さくなるように形成され、重ね合わせ面は平滑で均等に接触する構成とした。【選択図】図１
