FRICTIONAL VIBRATION DAMPING DEVICE
PROBLEM TO BE SOLVED: To provide a frictional vibration damping device having a simple structure and high workability, functioning effectively at times of medium- and large-scale earthquakes, and offering a similar vibration damping effect as with when the number of slip surfaces is two, even when the number of the slip surface is one.SOLUTION: A frictional vibration damping device includes a disc-form first slipping flat plate in contact with a groundsill or a foundation, and a disc-form second slipping flat plate in contact with the foundation or a pile head. One or more ring-formed projections of an almost isosceles trapezoidal shape is provided on a surface of the second slipping flat plate. A ring-formed ring covering groove of an almost isosceles trapezoidal shape is engraved on a bottom surface of the first slipping flat plate, the ring covering groove having a cross-section of an almost isosceles trapezoidal form that expands in a downward direction and being placed opposite the ring-formed projection to cover over the ring-formed projection. The first slipping flat plate includes a raising part that adjusts a thickness of the slipping flat plate.SELECTED DRAWING: Figure 1
【課題】簡単な構造で施工性に優れ、中規模や大規模地震に有効に機能する摩擦減震装置であって、滑り面が１つであっても２つの場合と同様の減震効果を得ることができる摩擦減震装置を提供する。【解決手段】土台または基礎に接触する円盤状の第１の滑り平板と、基礎または杭頭に接触する円盤状の第２の滑り平板とからなり、前記第２の滑り平板の表面には略等脚台形を呈する１つ以上のリング状のリング突条が凸設される一方、該第１の滑り平板の底面には断面が下方向に広がる略等脚台形を呈し該リング突条に対置して該リング突条を跨るように被包する略等脚台形でリング状のリング被包溝が刻設され、前記第１の滑り平板はその厚さを調整する嵩上げ部を有する、構成とした。【選択図】図１
