PURPOSE: To minimize binding force to PC boards in case of concrete placement by providing a column form at least over the entire surface of a wall 1 consisting of the PC boards, and providing a separator capable of moving to the column form to place concrete.
CONSTITUTION: A column form for column construction is provided at least over the entire surface of a wall 1 consisting of PC boards 2. The column form is built to the column form body and PC boards 2 by selecting cones 7 and separators 5 of plastic, etc., and shells 6 such as a vinyl tube are mounted to the separators 5 to build. In addition, the separators 5 are provided so that they are capable of moving against concrete of a column section 3. After that, concrete is placed to the shells 6.
