VIBRATION REDUCING FOUNDATION STRUCTURE FOR ARCHITECTURAL STRUCTURE

INUKAI SHIGENAO

PROBLEM TO BE SOLVED: To provide a vibration reducing foundation structure for architectural structure, which can be extremely simply and economically constructed and allows a friction force to be adjusted depending a load applied to each section of a plane position of a building and has an effective vibration reducing action.SOLUTION: In a vibration reducing foundation structure for an architectural structure, a foundation of the architectural structure comprises a base part 1 and a movable foundation part 2 disposed on the top face of the base part. An upper sliding plate 23 is disposed on the undersurface of the movable foundation part 2. A lower sliding plate, which faces and slidably contacts the upper sliding plate 23, is disposed on the top face of the base part 1. The upper sliding plate 23 is made of a sliding-face plate. A holding plate 11a and the sliding-face plate 11b on which multiple balls are fixed are used as the lower sliding plate and assembled to form the base part 1. Multiple swollen parts 10 rising from the top face of the base part 1 are formed on the top face. The holding plate 11a and the sliding-face plate 11b on which multiple balls are fixed are disposed on swollen faces of the swollen parts 10.SELECTED DRAWING: Figure 2

【課題】極めて簡明で経済的に構成することができ、建物の平面位置の場所ごとにかかる荷重に応じた摩擦力を調整し得、有効な減震作用を発揮する建築物用減震基礎構造を提供する。【解決手段】建築物用減震基礎構造は、建築物の基礎を、基盤部１と、その上面上に配置する可動基礎部２とで構成し、可動基礎部２の下面に上側摺動板２３を配置し、かつ基盤部１の上面に上側摺動板２３に対面して摺接する下側摺動板を配置し、上側摺動板２３は、滑面の板材で構成し、下側摺動板として、複数のボールを固設した保持板１１ａ及び滑面の板材１１ｂを採用し、それらを組み合わせて基盤部１を構成する。また、基盤部１の上面に該上面から立ち上がる複数の膨出部１０を構成し、この膨出部１０の各膨出面に複数のボールを固設した保持板１１ａ及び滑面の板材１１ｂを配置する。【選択図】図２
