PROBLEM TO BE SOLVED: To easily adjust the width of a form to a prescribed form width regardless of arrangement of reinforcements in the form when the width of the form is different from the prescribed width due to distortion in the form for placing concrete. SOLUTION: Abutting plates are jointed to both shafts of a dimension adjusting apparatus comprising an expansion member for adjusting the width of the form, and a fixture for fixing the length of the expansion member. The abutting plates are fixed to the form to adjust the width of the form to the prescribed form width by the dimension adjusting apparatus.
