PROBLEM TO BE SOLVED: To make it possible to largely reduce the cost of a pressure molding form apparatus in the case of pressure molding concrete segment and to further improve a sense of beauty of a pressed concrete product without requiring the finishing step after releasing from the form. SOLUTION: The pressure molding form apparatus comprises a groove-like lower frame 2 charged with concrete, a pressure molding upper cover 3 mounted on the opening of the frame 2 at the time of pressure molding the concrete, and a pressure holding upper cover 4 mounted on the opening of the frame 2 instead of the cover 3 after the molding. The cover 3 is prepared only one for many forms by using only at the time of the molding, and the covers 4 of a simple structure are prepared by the number corresponding to the number of the forms by using the covers 4 at the time of curing. Concrete surface is smooth finished in the case of replacing the cover 3 with the cover 4. |
