PROBLEM TO BE SOLVED: To reduce time and labor for construction, to shorten a construction period and to reduce cost by carrying out simultaneous construction without using a permanent form 1 in juxtaposing concrete columns in proximity. SOLUTION: In constructing the concrete columns juxtaposed with a clearance, facing surface form face materials 2, 3 are arranged along the facing surfaces which face with the clearance in the respective concrete columns, and outer peripheral surface form face materials 4, 5 are arranged along the outer peripheral surface other than the facing surfaces and joined to both side ends of the facing surface form face materials 2, 3. The facing surface form face materials 2, 3 are formed with face plates 2a, 3a along the facing surfaces, and a plurality of horizontal ribs 2b, 3b provided at predetermined spaces in a vertical direction at the back faces of the face plates 2a, 3a. The horizontal ribs 2b, 3b of the facing surface form face materials 2, 3 are arranged to overlap in a plane with the height positions different from one another. COPYRIGHT: (C)2008,JPO&INPIT
