PURPOSE: To make construction possible for a column base structural body that have walls in optional thickness and is excellent in availability for construction in site and accommodative to steel elements that can be manufactured and transported efficiently. CONSTITUTION: An internal steel element 21 and an external steel element 22 are equipped respectively with a flange steel plate 1 and a plurality of connecting steel members 3 fixed at a right angle against the flange steel plate 1, and joints 2 are provided at the front end of the connecting steel members 3. The internal steel elements 21 are erected first, and the adjoining internal steel elements 21 are joined together by welding at vertical joints 31. Then, the external steel elements 22 are erected with their joints 2 engaged with the joints 2 of the internal steel elements 21, and welding is made from the outside at horizontal joints 32 and the vertical joints 31. Then, concrete 11 is placed into a space between the internal steel elements 21 and the external steel elements 22. With the above-mentioned processes repeated and erection made upward, a column base structural body in a composite structure of steel and concrete is constructed. |
