To contrive the improvement of assembling workability by continuously contacting each plate piece of an inorganic fiber molding plate constituting a solid shaped developing shape by a continuous contact sheet in at least the adjacent edge of the plate piece and assembling them into three-dimensional shape.
The assembling body 1 of an inorganic fiber molding comprising each plate piece constituting a three-dimensional shape provided with a quadrangular pyramid is molded. The joined part of the plate piece 2 of the assembling body 1 constituting a developing shape is made a fold, and the plate pieces 2 positioned on both the ends are folded. Next, the joined part of the plate piece 2 positioned on the center of the assembling body 1 is made the fold to be folded, the non-connection end face 5 of the plate piece 2 positioned on both the ends of the assembling body 1 is made a matched margin to be joined, and the inorganic fiber molding provided with the shape of the quadrangular pyramid is assembled. Thus, the corner part of the three-dimensional shape is made an acute angle, and excellent external appearance can be possessed.
