PROBLEM TO BE SOLVED: To provide a simple foundation which is easily assembled as a foundation of a building without using a large machine or the like in the construction field, and easily removable to be returned to its original state when it becomes unnecessary. SOLUTION: The simple foundation is formed of a concrete main body 4 having a polygonal columnar drum 2 and a conical bottom 3; a connection member 6 erected from the drum 2; curved through holes 7 penetrating through the main body 4 in a manner being extended along an axial direction of the main body 4 and being curved along at least part of an axis in a circumferential direction; and first bearing members each formed of a curved reinforcement 9 guided by the curved through hole 7 and driven into the ground. The foundation is further provided with a spiral through hole 8 formed in the center of the main body 4 in a manner being spirally extended along the axial direction of the main body, and a second bearing member formed of a spiral reinforcement 10 guided by the spiral through hole 8 and driven into the ground. The main body 4 is connectable to the other main body 4 such that side surfaces of the drums 2 are abutted on each other. COPYRIGHT: (C)2005,JPO&NCIPI
