| 摘要 | PURPOSE:To upgrade the accuracy of forming a casting mold and to improve the service life of a wooden pattern by constituting the wooden frame in the wooden pattern of a skeleton assembled of reinforcing core materials such as metallic sheet and rods as well as rail members such as timber or the like fitted embracively to the surface of said core materials. CONSTITUTION:Reinforcing core material such as a metallic sheet or rod is used for a core material 25 forming a skeleton of a wooden frame 20 in a wooden pattern. A rail member 26 consisting of sized timber or the like is fitted embracively to the surface of the material 25. The embracive fitting of the core material and the member 26 is accomplished by providing, for example, through- holes (h) and fixing both by screwing, etc. Plate materials 30 are adhered to the inside and outside surfaces of the frame 20 formed in the above-mentioned way to complete the wooden pattern. The accuracy in molding is thus improved without generating deformation and damage of the wooden pattern during transportation and molding and the service life of the wooden pattern is improved. Such wooden pattern is suitable for manufacturing the large-sized wooden pattern into one body. | ||||||
