COOPERATION MECHANISM OF ANCHOR BOLT AND FRICTION SEISMIC REDUCTION DEVICE
To provide a friction seismic reduction device suitable also to a no joist method and provide a cooperation mechanism to cause more effect than conventional one by a cooperation of an anchor bolt and the friction seismic reduction device.SOLUTION: In a cooperation mechanism of an anchor bolt and a friction seismic reduction device, the anchor bolt buried in a foundation is inserted into an open hole penetrating a sill and tightened by a nut with a round seat to fix the sill to the foundation, the friction seismic reduction device including a first sliding flat plate in contact with the sill and a second sliding flat plate situated at a lower stage and in contact with the foundation is inserted between the foundation and the sill between the anchor bolts, the open hole comprises a first open hole and a second open hole in order from a surface of the sill, a diameter of the first open hole is substantially same with an outer diameter of the nut with a round seat and a diameter of the second open hole is larger than the diameter of the first open hole, a length of the first open hole is longer than a long nut part of the tightening nut, and a ratio of length of the first open hole to a length of the second open hole is 1:1 or 1:2.SELECTED DRAWING: Figure 1
【課題】根太レス工法にも適した摩擦減震装置を提供し、アンカーボルトおよび摩擦減震装置が協働して従来以上の効果を生じさせる協働機構を提供する。【解決手段】基礎に埋設されたアンカーボルトが土台を貫通する貫通孔に挿入されて丸座付きナットで締め付けられて該基礎に該土台が固定され、前記アンカーボルト間の基礎と土台との間には該土台に接触する第１の滑り平板と、下段に位置し該基礎に接触する第２の滑り平板と、からなる摩擦減震装置が介挿され、前記貫通孔は前記土台の表面から順に第１の貫通孔および第２の貫通孔からなり、該第１の貫通孔の直径は前記丸座付きナットの外径と略同一であり、該第２の貫通孔の直径は前記第１の貫通孔の直径よりも大きく形成されるとともに、該第１の貫通孔の長さは該締付ナットの長ナット部よりも長く、かつ該第１の貫通孔の長さおよび該第２の貫通孔の長さの比率は１：１ないし１：２である、構成とした。【選択図】図１
