A receiving side locking part 25 is provided on the side, but in some cases, a protruding side engaging part 24 is provided on both end faces.
Alternatively, the panel plates provided with the receiving side locking portions 25 may be connected alternately.

As shown in FIG. 2A, the protruding side engaging portion 24 causes the end portions of the plate materials 22 and 23 to protrude toward the end surface of the adjacent panel plate 20' at both side portions of the panel plate end face, and the protruding end A protrusion 24 having a U-shaped cross section and having a space inside by folding back the
A substrate 26 having a U-shaped cross section is disposed between the protrusions 241 and 242 so as to form an end surface of the panel board.

The receiving side locking portion 25 is as shown in FIG. 2A.
It is composed of a pair of groove pieces 251, 252 made by making the end portions of the plate materials 22, 23 protrude from the end face of the panel plate, folding the protruding portions toward the inside of the panel plate, and then folding back the folded ends. The groove pieces 251, 252 have grooves 251', 252' each having a U-shaped cross section and opening toward the end face of the adjacent panel plate 20''.

A board 27 having a U-shaped cross section is attached to the end face of the panel board 20 on which the receiving side locking part 25 is provided so as to open outward. 251 and 252 are accommodated, and a heat insulating packing material 28 is filled between the pair of groove pieces 251 and 252.
