SLIDING SUPPORT SEISMIC ISOLATOR, LAMINATION RUBBER SEISMIC ISOLATOR AND STRUCTURE SEISMIC ISOLATOR COMBINED WITH SLIDING SUPPORT SEISMIC ISOLATOR
PROBLEM TO BE SOLVED: To provide a sliding support seismic isolator that can be well combined with a lamination rubber seismic isolator caused by occurrence of depression when the isolator is operated.SOLUTION: A slide supporting base isolation device 10 arranged between an upper structure 12 and a lower structure 14 of a structure comprises a slide plate 20 connected to the lower structure and extending substantially in a horizontal direction, and a sliding member 34 connected to the upper structure. The sliding plate 20 has an upper surface defining a sliding surface 24. The sliding member 34 has a lower surface defining a sliding contact surface 36 contacted with the sliding surface. When the sliding member 34 slips on the sliding surface 24 of the sliding plate 20, a relative motion of the upper structure 12 in respect to the lower structure 14 in a horizontal direction is allowed. The sliding surface 24 of the sliding plate 20 is substantially formed into a salient surface shape forming a partial spherical surface shape, thereby the sliding member 34 is displaced relatively in a horizontal direction in respect to the sliding plate 20 and moved away from its neutral position, the sliding member 34 is displaced in a vertical lower direction.SELECTED DRAWING: Figure 1
【課題】作動時に沈下が発生するようにすることで、積層ゴム免震装置と良好に併用し得るようにしたすべり支承免震装置を提供する。【解決手段】構造物の上部構造体１２と下部構造体１４との間に配設されるすべり支承免震装置１０は、下部構造体の側に連結されて略々水平に延展するすべり板２０と、上部構造体の側に連結されるすべり材３４とを備え、すべり板２０はその上面がすべり面２４を画成しており、すべり材３４はその下面がこのすべり面に摺接する摺接面３６を画成している。すべり材３４がすべり板２０のすべり面２４上を滑動することで上部構造体１２の下部構造体１４に対する水平方向の相対移動が許容される。すべり板２０のすべり面２４は略々部分球面形状を成す凸面形状に形成されており、それによって、すべり材３４がすべり板２０に対して相対的に水平方向に偏位して中立位置から離れるにつれて、すべり材３４が鉛直下方へ偏位するようにした。【選択図】図１
