METHOD FOR CONSTRUCTING BASE ISOLATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a method for constructing a base isolation structure capable of curbing a reduction in aseismic performance even when skeleton concrete shrinks.SOLUTION: In a building 1 which has a base isolation structure, an upper foundation beam 12 is supported by a base isolation device 20 installed on a mat slab 11. A method for constructing the building 1 comprises: steps S3 to S5 to construct the upper foundation beam 12 with a length longer than a design length in anticipation of shrinkage of concrete thereof and to temporarily support the upper foundation beam 12 so that the same can slide on the mat slab 11; and step S6 to install laminated rubber 201 between the upper foundation beam 12 and the mat slab 11 after the lapse of predetermined time and to support the upper foundation beam 12 with the base isolation device 20 including the laminated rubber 201.SELECTED DRAWING: Figure 2
【課題】躯体コンクリートが収縮しても、免震性能の低下を抑制できる免震構造物の構築方法を提供すること。【解決手段】免震構造物の建物１は、マットスラブ１１の上に設けられた免震装置２０により上部基礎梁１２を支持する。この建物１の構築方法は、上部基礎梁１２のコンクリートの収縮量を見込んで、上部基礎梁１２を設計上の寸法よりも長く構築するとともに、この上部基礎梁１２をマットスラブ１１から摺動可能に仮支持するステップＳ３〜Ｓ５と、所定期間経過後、積層ゴム２０１を取り付けて、この積層ゴム２０１を含む免震装置２０により上部基礎梁１２を支持するステップＳ６と、を備える。【選択図】図２
