ATTACHED FOUNDATION AND METHOD OF CONSTRUCTING THE SAME

PROBLEM TO BE SOLVED: To provide an attached foundation easily installable on an existing foundation and integrated with each other and a method of constructing the attached foundation. SOLUTION: When the attached foundation 2 is constructed on the outer side of the continuous foundation 1 of an existing building H, first a frame 21 for foundation is set in a frame guide groove 28, and then the frame 21 is driven from its tip so that the edge 26 of a blade body 25 extended in a diagonal upper side abuts on the side face of the continuous foundation 1. The blade body 25 is disposed along the side face of the continuous foundation 1 so that it is slightly deformed and energized when it touches the side face of the continuous foundation 1. Since a space S is formed between the continuous foundation 1 and the frame 21, concrete is deposited in the space to form the attached foundation 2. Even if an upward extraction force against the continuous foundation 1 is generated in this attached foundation, the attached foundation 2 is prevented from rising since the blade body 25 bites in the side face of the continuous foundation 1.
