CURVED-SURFACE BODY STRUCTURE, AND CURVED-SURFACE BODY MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide curved-surface body structure which is reinforced by tongue pieces by alternately arranging the tongue pieces on two sides of a nearly-triangular plate member and forming a curved-surface body by combining the tongue pieces in a pectinate shape, and can keep a stable curved shape regardless of its diameter size. SOLUTION: In this curved-surface body structure, triangular plate members in each of which three nearly-triangular sides are formed into projecting curved surfaces, and pectinate tongue pieces are alternately formed on two sides forming an apex angle are prepared as many as one curved-surface body can be made, and the curved-surface body is formed by alternately engaging and incorporating the tongue pieces of the triangular plate members with/into one another.
