BASE-ISOLATION REPAIR STRUCTURE FOR EXISTING BUILDING, AND BASE-ISOLATION REPAIR METHOD FOR EXISTING BUILDING
PROBLEM TO BE SOLVED: To renovate an intermediate course of an existing building into a base-isolated course without directly reinforcing an existing lower beam positioned in a lower part of the intermediate course.SOLUTION: A base-isolation repair structure for an existing building includes: a downside lower column that is provided by cutting and leaving an existing column in an intermediate course of the existing building; an upside upper column that is provided by cutting and leaving the existing column; a base-isolating device that is installed on the lower column to support the upper column; a lower reinforcing beam that is supported by the lower column and provided above an existing floor slab; and an upper reinforcing beam that is supported by the upper column and provided below an existing upper beam.SELECTED DRAWING: Figure 1
【課題】中間層の下部に位置する既設の下梁を直接補強せずに、既設建物の中間層を免震層に改修する。【解決手段】既設建物の中間層にある既設柱を切り残して設けられた下側の下柱と、前記既設柱を切り残して設けられた上側の上柱と、前記下柱上に設置され前記上柱を支持した免震装置と、前記下柱に支持され既設床スラブの上方に設けられた下補強梁と、前記上柱に支持され既設上梁の下方に設けられた上補強梁と、を有する既設建物の免震改修構造。【選択図】図１
