Therefore, recently, there has been proposed a construction method in which the ventilation holes are blindfolded by blades that are obliquely attached at appropriate intervals. As an example, as shown in FIG. 20, the ventilation holes a are provided. On the surface side of the perforated plate b, the wing plates c are vertically arranged side by side in a state of being floated from the perforated plate b, and both side ends of the wing plate c are supported by the frame frames d located on both sides thereof. Are known.

(Problems to be solved by the invention) However, this construction method has the following problems.

That is, since the wing plate must be supported by both side ends thereof, the wing plate mounting structure must be complicated, and it is difficult to mount the wing plate at a construction site. For this reason, since the blades that are preassembled at the factory must be attached to the building, there is a problem that it cannot be processed into a free size and shape suitable for the building.

In addition, there is a problem that the manufacturing cost is high due to the complicated mounting structure of the wing plate, and that the mounting strength is poor because the wing plate is supported only at both end portions.

In view of the above, it is an object of the present invention to provide a ventilation building board that has a high-class appearance, yet can be processed into a size and shape that is free at a construction site and that has sufficient mounting strength. To do.
