BUILDING STRUCTURE AND CONSTRUCTION METHOD OF BUILDING STRUCTURE

To provide a building structure and a construction method of the building structure capable of suppressing stress creation and deformation due to cooling.SOLUTION: A cold storage comprises a storage space cooled in low temperature, wherein a seismic isolator 18 is placed between an upper foundation 12 and a lower foundation 11 of a foundation F1. The cold storage comprises side surface heat insulation material 31 covering a side surface of a second installation part 12a of the upper foundation 12, and side surface heat insulation material 32a, 33a and bottom surface heat insulation material 32b, 33b covering side surfaces and lower surfaces of large beams 12a, 12c of the upper foundation 12, respectively. Further, the cold storage is provided with underfloor heat insulation material 17 covering a lower surface of a slab body 16 of a first floor slab 15.SELECTED DRAWING: Figure 2 【課題】冷却による応力の発生や変形を抑制することができる建物構造及び建物構造の施工方法を提供する。【解決手段】冷凍倉庫は、低温に冷却した保管空間を有し、基礎Ｆ１の上部基礎１２と、下部基礎１１との間に免震装置１８を配置している。冷凍倉庫は、上部基礎１２の第２設置部１２ａの側面を覆う側面断熱材３１、上部基礎１２の上部大梁１２ｂ，１２ｃの側面及び下面をそれぞれ覆う側面断熱材３２ａ，３３ａ及び底面断熱材３２ｂ，３３ｂを有する。更に、冷凍倉庫は、１階床スラブ１５のスラブ本体１６の下面を覆う床下防熱部材１７を備える。【選択図】図２
