PROBLEM TO BE SOLVED: To provide manufacturing method for a construction panel, without large scale facility, and coping with small lot multi-kinds production. SOLUTION: Irregularity is formed onto a metallic plate 5 by a plate press die composed of female and male dies 1 and 2, and after that, the plate 5 is horizontally moved in a longitudinal direction to form the irregularity onto a portion where the irregularity is not formed. Then, both end parts in the longitudinal direction are folded to be worked so that a cross section shape can have a neary hat state, and a back surface material is joined to a back surface side to form a synthetic-resin foaming body in a gap part to manufacture a construction panel. |
