PURPOSE: To facilitate a work to build a body and to increase a working speed, by a method wherein a scaffold and a form frame to support forms are formed separably from each other and relatively slidable, and the scaffold is lifted up during curing of concrete to perform a preparing work.
CONSTITUTION: A number of frames are assembled together, and scaffolds 10 by which a plurality of sections are formed longitudinally of a body A, are so formed that they are elevatable by means of center hall jacks 2 and 2 and screw bars 3 and 3. Form frame 20 to support forms 5 and 6 is so formed that it is elevatable by means of chain blocks 4 and 4. After concrete is placed, only the scaffold 10 is lifted up by one pitch during curing of the concrete to perform a preparing work for the surroundings of the scaffold 10, e.g. connection of steel frames B1 and reinforcing bars (b), movement of center hall jacks 2. After the forms 5 and 6 at a lower stage are removed and lifted up and moved to a given position, the forms are set to place concrete.
