<p>PROBLEM TO BE SOLVED: To provide a foundation structure having a prescribed strength and deformation performance at a low cost by placing a demolition rubbish concrete between an upper reinforced concrete and a lower reinforced concrete and by giving it rolling. SOLUTION: A lower reinforced concrete 1 is formed almost horizontally, and side reinforced concretes 2 and 2 are formed on the face of its upper side. Next, a demolition rubbish concrete 4 mixed with a demolition rubbish is placed in an area surrounded by the side reinforced concrete 2 over lower reinforced concrete 1 and given rolling. Then, on the demolition rubbish concrete 4, an upper reinforced concrete 3 is formed almost horizontally. It is desired that a shear key 7... is provided between the upper reinforced concrete 3 and the lower reinforced concrete 1 to have favorable stress transmission.</p> |
