PURPOSE: To shorten working time by providing a dedicated form in such a way as capable of freely ascending and descending on the operation of a form lifting device, and installing the device in such a way as freely shiftable on the operation of a shift device therefor. ;CONSTITUTION: The specified form among many dedicated forms arranged in parallel is elevated with a form lifting device 34 installed on the concrete placement 64 plane of a concrete structure 50. Then, a worker climbs the form along the surface thereof and fastens the lower side of the form to a dummy bolt erected in advance on the plane 64. Then, the worker further climbs the form along the surface thereof and fastens the upper side of the form to another dummy bolt erected on the plane 64. Furthermore, after concrete is placed and cured in the form, the fastened state thereof is released. When a form for another concrete placement plane 64 is elevated, the form lifting device 34 is moved with a shift device therefor.;COPYRIGHT: (C)1994,JPO&Japio
