It will be.

  On the other hand, for example, even if the plate member 3 is to be deformed into a square shape in a plan view, as described above, the one horizontal member 4c, 5c and the other horizontal member 4d, 5d on both surfaces of the plate member 3, The deformation is suppressed.

  Further, for example, even if the plate 3 is deformed so as to be twisted, it is deformed in the entire frame bodies 4 and 5 made up of the vertical and horizontal flanges 4a, 4b, 4c, 4d, 5a, 5b, 5c, 5d on both sides of the plate 3. Can be suppressed.

  Moreover, since the vertical and horizontal saddle members 9, 9a, 10, 10a are provided inside the frame bodies 4, 5 on both sides of the plate member 3, the vertical and horizontal saddle members 9, 9a, 10, 10a are provided. Thus, the frames 4 and 5 can be reinforced, and the reinforced frames 4 and 5 strengthen the force for suppressing the deformation of the plate member 3.

  Therefore, even if the plate member 3 is deformed in any direction, the frame members 4 and 5 and the vertical and horizontal saddle members 9, 9a, 10 and 10a can suppress the deformation. 3 and the frame 4 and 5 are hardly affected, and the strength against an earthquake or the like can be improved.
