FORM FOR CENTRIFUGALLY MOLDING CONCRETE

Document Type and Number:

Japanese Patent JPH1158354

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To obtain a form for centrifugally molding concrete to easily replace a packing with effective sealability. SOLUTION: In the form for centrifugally molding concrete used by flange- coupling a pair of split forms 1, 2, a stopper 8 is fixed to inside of the flanges 5. And, a compressive packing 10 having a large thickness than that of the stopper is detachably fixed. And, when the flanges are coupled therebetween, a gap is formed between ends of body plates in the split forms, and the gap is substantially brought into coincidence with the flange-coupled part.
