PROBLEM TO BE SOLVED: To provide a slide bearing for a structure for largely attenuating seismic energy by largely forcedly deforming an elastic bearing, together with friction damping by a slide of a slide surface to horizontal displacement of acting in earthquake time.SOLUTION: A slide bearing device comprises an upper shoe 5 fixed to an upper structure 3, a lower shoe 4 fixed to a lower structure 2 and an elastic bearing 8 arranged between the upper shoe and the lower shoe and integrating upper-lower part connection plates 10 and 11 above and below an elastic body 9 and an intermediate part connection plate 12 in an intermediate part of the elastic body, and one of an upper plate and a lower plate is fixed to the upper shoe or the lower shoe, and a slide plate 14 is fixed to the other of the upper plate and the lower plate, and the intermediate part connection plate is formed with a lock part for transmitting displacement in orthogonal one direction by engaging with a displacement transmission part arranged in the upper shoe or the lower shoe for forming a slide plate and a slide surface, and the upper shoe and the lower shoe is arranged with a member for checking the movement in the orthogonal other direction of the slide plate and the intermediate part connection plate.SELECTED DRAWING: Figure 1
【課題】地震時に作用する水平変位に対してスライド面のスライドによる摩擦減衰とともに、弾性支承を大きく強制変形させることにより地震エネルギーを大幅に減衰する構造物用スライド支承を提供する。【解決手段】上部構造３に固定される上沓５と、下部構造２に固定される下沓４と、前記上沓と下沓の間に配置され、弾性体９の上下に上下部連結プレート１０、１１と弾性体の中間部に中間部連結プレート１２を一体化した弾性支承８とを備え、上部プレートと下部プレートの一方を上沓又は下沓に固定し、上部プレートと下部プレートの他方にスライドプレート１４を固定し、中間部連結プレートに前記スライドプレートとスライド面を形成する上沓又は下沓に配置した変位伝達部と係合して直交する一方の方向の変位を伝達するロック部を形成し、上沓と下沓に前記スライドプレートと中間部連結プレートの直交する他方の方向の移動を阻止する部材を配置する。【選択図】図１
