PROBLEM TO BE SOLVED: To provide a method for preventing the deformation of a thin precast placing frame mold, by controlling an evaporated amount of water from a face attached to concrete or a finished face of concrete during a curing period to prevent the deformation of the face. SOLUTION: After removal of the mold of a thin precast placing frame mold, parts 22A1 of an uneven molding product 22A are peeled from a face 11B attached to concrete, the area of the face 11B attached to concrete approximately equal to the total area of joint parts 14 between finishing materials 13 of a finishing face 11A exposed to an atmosphere is exposed to an atmosphere, the evaporated amount of water from the face 11B attached to concrete is made approximately equal to that from the finishing face 11A to carry out the curing of the thin precast placing frame mold. The deformation caused by difference in evaporated amount of water between the surface and the back of the frame mold can be prevented and a placing frame mold having a desired precision free from cracks can be efficiently produced. |
