SOLUTION: An assembled inner frame 2 is stored and fixed in a formwork body 1 for manufacturing and at the same time, an embedded fitment 8 is held, in a suspended state, inside the inner frame 2. Next, concrete is poured into the inner frame 2 and is vibrated, and after that, the inner frame 2 is immediately carried out of the shuttering body 1.
