PROBLEM TO BE SOLVED: To simplify work labor for installing timbering for restraining deformation of a driving column form by lateral pressure at concrete placing time as well as to simplify work labor for setting the driving column form and work labor for connecting mutual steel plate driving forms. SOLUTION: This driving column form is composed of metallic or resin or fiber frame plates 9a to 9d, a column hoop 4 or core reinforcements 5 and 6, column hoop receiving tools 1 composed of an annular outer frame 2 and a lattice-shaped body 3 and reinforcing materials 11a to 11d of a fiber sheet or a folded steel plate for reinforcing a corner part of the column form. When forming the driving column form, since the column hoop receiving tools 1 for fixing the column hoop on the inside of the column form are arranged in large numbers at prescribed intervals (minimum 3 cm and maximum 10 cm) in the shaft direction of the column form, mutual frame plates are easily joined in the corner part of the column form, and since deformation of the form by lateral pressure of placing concrete is restrained by the column hoop receiving tools 1, the work labor for installing the timbering can be simplified.
