As panels of this type, those shown in FIGS. 6 to 8 are conventionally known.

The panel shown in FIG. 6A has a structure in which a heat insulating material (B) is adhered to one surface of a structural face material (A).
The heat insulating material (B) is fitted between the shaft assemblies (C) and (C), and the peripheral portion of the structural face material (A) that protrudes from the outer periphery of the heat insulating material (B) in an ear shape is the shaft assembly (C). , (C) and fixed by nails. In addition, the panel shown in FIG. 7A has a rectangular frame (D) on which a structural surface material (A) is stuck on one side and a heat insulating material (B) inside the frame (D). ) Is installed, and the frame (D) is inserted between the frames (C) and (C), and the structural face material (A) extends like an ear from the outer periphery of the frame (D). The periphery is joined to the frames (C) and (C) and fixed by nails. Further, the panel shown in FIG. 8A has a structure in which a structural face material (A) having substantially the same outer shape is attached to one surface of a rectangular frame (D). The frame (D) fitted between the frames (C) and (C) together with the structural face material (A) is nailed to the frames (C) and (C) from the inside thereof, and this frame (D) The heat insulating material (B) is installed inside ().

[0004]

By the way, in the panel shown in FIG. 6 (a), as shown in FIG. 6 (b), when the panel is to be mounted on the shaft set (C) at the corner, the structural surface The backing materials (E) and (E) for nailing the peripheral parts of the materials (A) and (A) need to be fixed to the frame (C) in advance, and the construction is complicated. In addition, in the panel shown in FIG. 7A, when the panel is assembled to the corner set (C) as shown in FIG. 7B, adjacent structural face materials (A),
The left and right peripheral edges of (A) are cut off by a predetermined amount so as not to interfere with each other, and the heat insulating materials (B) and (B) are removed, and the frames (D) and (D) are pivoted from the inside thereof. It is necessary to fix the nail to the set (C), and the construction is extremely complicated.
