Abstract
PURPOSE: To manufacture a molding tool, made of concrete and having high strength, by a method wherein through holes, penetrating the main body of the tool, are formed in the process of pouring concrete slurry and curing it and another process of inserting bolts into the through holes and heating them is provided while nuts are screwed to the bolts, heated to a predetermined temperature.
CONSTITUTION: A frame 6 and an upper frame 7 are attached to a model 5, then, concrete slurry 8 is poured to form the main body of a molding tool while through holes 12, penetrating through the main body, are formed during the process of curing the concrete slurry. Preheated bolts 13 are inserted into the through holes 12 and reinforcing steel plates 15, through which the bolts 13 are penetrated, and abutted against both side surfaces of the main body 11 of a molding tool and nuts 16 are screwed to the bolts 13 from the outside while the nuts are tightened loosely before the bolts 13 are cooled. According to this method, varieties in friction force when the nuts are turned may be reduced and the tensions of the bolts may be made constant. A plurality of through holes 12 and bolts 13 for providing the main body 11 of the molding tool with tension is arranged in the up-and-down relation as well as fore-and-aft. direction.
