BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation wall panel which can improve breathability and can prevent dew condensation especially in winter.

[0002]

2. Description of the Related Art In recent years, a so-called panel construction method in which floors, roofs and the like are formed by using panels has become widespread. The outer wall of a house of such a panel construction method is also formed by using a so-called wall panel, but the wall panel is formed as a so-called ventilation wall panel in order to discharge moisture inside the outer wall and prevent dew condensation especially in winter. In many cases.

As shown in FIG. 9, this ventilation wall panel p conventionally has a frame c formed by bridging vertical frame members b ... Inside a peripheral frame in which the frame members a are joined in a rectangular shape, and this frame member. An inner plate d and a base plate e respectively attached to the inner and outer surfaces of c, a ventilation base f formed of a plurality of, for example, plywoods vertically attached to the outer surface of the base plate e, and an outer surface of the ventilation base f. With the exterior plate g additionally provided, a vertical air passage h is formed between the ventilation substrates f and f adjacent to each other between the base plate e and the exterior plate g to ensure air permeability.

[0004]

However, in the ventilation wall panel p, the air flow is caused by the adjacent ventilation bases f, f.
Since the space is limited to the vertical direction and the degree of freedom is reduced, it may not be possible to sufficiently discharge the moisture in the wall.

Moreover, in the ventilation wall panel p provided with the window opening o as shown in FIG. 10, the air flow indicated by the arrow in FIG. 10 is blocked by the lower side of the window opening o. However, it was not possible to prevent the damage of dew condensation especially in the winter.

The present invention is based on the fact that the exterior plate is attached to the wall panel base body by using the fixing metal fitting having the pedestal portion forming the horizontal conduction path connecting the vertical air paths on both sides, and the degree of freedom of the air flow is set. Therefore, it is an object of the present invention to provide a ventilation wall panel that can improve the air permeability and can prevent dew condensation especially in winter.

[0007]

In order to achieve the above object, the ventilation wall panel of the present invention is a frame formed by bridging a vertical frame member inside a peripheral frame in which the frame members are joined in a rectangular shape. Interior plate attached to the inner surface facing indoors, base plate attached to the outer surface facing the exterior of the frame, and heat insulating material loaded into the space formed by the frame member of the frame, the interior plate and the base plate A wall panel base body, and an exterior plate that covers the wall panel base body with vertical air paths extending vertically on both sides of the fixing bracket by being attached to the outer surface of the base plate of the wall panel base body through the fixing brackets. The fixing metal fittings form a horizontal passage that connects the vertical air passages on both sides with each other, or the fixing metal fittings are vertically and continuously attached to each other so that the vertical air passages on both sides of the air passage are connected to each other. On the pedestal part that forms the horizontal conduction path that connects the path, The mounting piece is provided for mounting the Kigaiso plate.

[0008]

[Function] By attaching the exterior plate to the outer surface of the base plate of the wall panel base body through the fixing metal fittings, vertical air passages extending vertically are formed on both sides of the fixing metal fittings, and the vertical air passages are formed by the fixing metal fittings. It is succeeded by the horizontal conductive path. Therefore, the air can flow vertically and horizontally between the base plate and the exterior plate through the vertical ventilation path and the horizontal conduction path, so that the degree of freedom can be increased and the air permeability can be improved. Can be efficiently achieved, and even a ventilation wall panel having a window opening can prevent dew condensation in winter.

Further, since it is not necessary to attach the ventilation bases f ... As in the conventional case, the labor of the construction can be saved.
