Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To realize the easy demolding of a molding and, at the same time, a form having excellent durability, weatherability, heat resistance and the like. SOLUTION: As the stock of a form 1, an ethylene propylene rubber- containing vulcanizing rubber is employed. By kneading this stock rubber and a compounding agent, a green sheet is produced. The green sheet is placed on a metal model, which faithfully imitate a concrete panel 5 and, after its periphery is surrounded with iron frames, is vulcanized under pressure and heat so as to form a form 1. A concrete stock 6 is cast in the molding recessed part 3 of the form 1, within which an uneven pattern 4 is formed. After the stock is solidified under pressure, a resultant molding is demolded so as to obtain a concrete panel 5. Thus, the demolding of the molding becomes easy due to the elastic deformation of the rubber of the form 1 and the form 1 having durability and weatherability and, at the same time, also favorable heat resistance can be obtained.
