ELASTIC WASHER AND FOUNDATION STRUCTURE USING THE SAME
PROBLEM TO BE SOLVED: To provide an elastic washer which is simple in structure, and exhibits a desired function, and a building foundation structure using the elastic washer.SOLUTION: In place of a conventional elastic washer, this elastic washer is provided which comprises a first plate-shaped member which is a metal-made member, has a first penetration hole whose diameter is slightly larger than a dimension D which allows the penetration of a bolt, and has a shape surrounded by a side face, an upper face and a lower face, and an elastic member which is formed of an elastic material, has a penetration hole whose diameter is larger than the dimension D, and has a shape surrounded by a side face, an upper face and a lower face. The upper face of the elastic member and the lower face of the first plate-shaped member contact with each other so that a virtual center axis being a center axis of the penetration hole and a virtual first center axis being a center axis of the first penetration hole coincide with each other, and are not displaced from each other, and a minimum dimension of the diameter of the penetration hole of the elastic member does not become smaller than the diameter D when the elastic washer is crushed by maximum rated force.
【課題】 簡易な構造で所望の機能を発揮する弾性座金とそれを利用した建物基礎構造とを提供しようとする。【解決手段】従来の弾性座金にかわって、金属製の部材であってボルトを挿入可能な寸法Ｄより僅かに大きな直径の第一貫通孔と側面と上面と下面とで囲まれる形状をもつ第一板状部材と、弾性材料製の部材であって前記寸法Ｄより大きな直径をもつ貫通孔と側面と上面と下面とで囲まれる形状をもつ弾性部材と、を備え、前記貫通孔の仮想の中心軸である仮想中心軸と前記第一貫通孔の仮想の中心軸である仮想第一中心軸とが一致してずれない様に前記弾性部材の上面と前記第一板状部材の下面とが接して、最大定格力で押し潰されたときに前記弾性部材の前記貫通孔の直径の最小寸法が直径Ｄを下回らない、ものとした。【選択図】 図３
