POLYHEDRAL SLIDE SUPPORT DEVICE FOR STRUCTURE
To provide a polyhedral slide support device for a structure which, with a simple structure, can slide against omnidirectional horizontal displacement occurring during an earthquake, reduce reaction force when upper and lower slide surfaces start to slide, is effective to stably reduce seismic energy against earthquakes of low magnitude and even works as a large brake against giant earthquakes.SOLUTION: A polyhedral slide support device for a structure includes: a slide member which is provided between an upper structure and a lower structure of the structure, in which upper and lower surfaces are in full contact with the upper structure side and the lower structure side to form an up-down slide surface and the friction coefficient of one slide surface of the upper and lower slide surfaces is set to be smaller than that of the other slide surface, and which can slide omnidirectionally; and a slide restriction member which is fixed to the upper structure side or the lower structure side and restricts to a certain range the omnidirectional slide of the slide member.SELECTED DRAWING: Figure 1
【課題】構造が簡単で、地震時に作用する全方向の水平変位に対してスライド可能で、上下スライド面のスライド開始時の反力を減少させ、低震度の地震に対する安定した地震エネルギー低減効果と巨大地震にたいしても大きなブレーキがかかる構造物用多面スライド支承装置を提供することを目的とする。【解決手段】構造物の上部構造と下部構造間に配置され、上下面が上部構造側と下部構造側と全面接触し上下スライド面を形成し、上下スライド面の一方のスライド面が他方のスライド面の摩擦係数より小さく設定され全方向にスライド可能なスライド部材と、上部構造側又は下部構造側に固定されスライド部材の全方向のスライドを一定範囲に制限するスライド制限部材と、を備えることを特徴とする。【選択図】 図１
