FOUNDATION STRUCTURE OF SMALL-SCALE BUILDING

PROBLEM TO BE SOLVED: To provide a foundation structure of a small-scale building, capable of easily restraining tilting of the small-scale building due to its unequal sinking, even if the planer shape of the small-scale building is neither a simple square nor a simple rectangle, of even if an adjacent building exists and a foundation structure is affected by propagation underground stress caused by the load of the adjacent building.SOLUTION: A foundation structure B of a small-scale building (building 1) is comprised of an upper floor slab 3 consisting of a soil cement slab extended to an outer periphery in the vicinity of the building 1 and formed by improving a shallow layer of the ground and an enclosing wall 4 consisting of a soil cement wall provided under and integrated with the lower part of the upper floor slab. The foundation structure B is constructed, while substantially matching the building 1 and the foundation structure B to each other so that the respective gravity center positions G, Gthereof overlap substantially each other in a vertical direction.
