PROBLEM TO BE SOLVED: To provide a method for manufacturing a curved panel with ribs to which an inner surface resin coated member and concrete are easily fastened. SOLUTION: Ribs are integrally molded on a flat plate-shaped member in a vertical direction and, subsequently, this flat plate-shaped member is wound around a curving fixture or the like to be held to a cylindrical shape and, thereafter, the holding of the cylindrical shape is released to obtain the curved inner surface resin coated member. By making the ribs vertical with respect to the curved inner surface resin, the fastening of concrete to the curved inner surface resin can be improved and the curved inner surface resin different in width or length can be inexpensively obtained by one curved fixture. |
