BUILDING FOUNDATION STRUCTURE AND CONSTRUCTION METHOD THEREOF
To provide a building foundation structure and a construction method for the building foundation structure, which can reduce stress transmitted to a lower ground and reduce construction cost by reducing the installation amount of foundation concrete.SOLUTION: A building foundation structure 1 comprises: a ground improving body 2 obtained by improving a surface layer ground G; and foundation concrete 3 installed on the ground improving body 2 on site. The foundation concrete 3 located below pillars 4 of a building includes upper and lower parts 3A, 3B having different shapes. The lower part 3B has a sectional inverse trapezoidal shape cut along a vertical surface including a horizontal direction O1 orthogonal to a horizontal direction connecting the adjacent pillars 4, 4 of the building. The upper part 3A has a flange-like part F1 which projects from the side edge M of the upper end of the sectional shape of the lower part 3B in the first horizontal direction O1.SELECTED DRAWING: Figure 2
【課題】下部地盤へ伝達される応力を低減すること、及び基礎コンクリートの打設量を削減して施工コストを低減する、建築物の基礎構造並びに建築物の基礎構造の施工方法を提供する。【解決手段】表層地盤Ｇを改良した地盤改良体２及び地盤改良体２上に現場で打設した基礎コンクリート３を含む建築物の基礎構造１であって、建築物の柱４の下方に位置する基礎コンクート３は、形状の異なる上部３Ａ及び下部３Ｂを有する。下部３Ｂは、建築物の隣り合う柱４，４間を結ぶ水平方向に直交する水平方向Ｏ１を含む鉛直面により切断した断面形状が逆台形状である。上部３Ａは、下部３Ｂの前記断面形状における上端の側縁Ｍから第１水平方向Ｏ１へ突出する鍔状部Ｆ１を有する。【選択図】図２
