DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation wall panel capable of improving air permeability and, in particular, preventing dew condensation in winter.

[0002]

2. Description of the Related Art In recent years, so-called panel construction methods of forming floors, roofs, and the like using panels have become widespread. The outer wall of a house with such a panel construction method is also formed using a so-called wall panel, but the wall panel is formed as a so-called ventilated wall panel in order to discharge moisture in the outer wall and particularly prevent dew condensation in winter. Often.

Conventionally, as shown in FIG. 4 , the ventilated wall panel p has a frame c formed by bridging a vertical frame b inside a peripheral frame formed by joining frame a in a rectangular shape, and this frame c, an inner plate d and a base plate e respectively attached to the inner and outer surfaces of the base plate e; a plurality of vertical ventilation bases f, for example, made of plywood attached to the outer surface of the base plate e; A vertical air passage h is formed between the adjacent ventilation bases f, f between the base plate e and the exterior plate g, so that air permeability is secured.

[0004]

However, in the ventilation wall panel p, the flow of air is reduced by the adjacent ventilation bases f, f.
As a result, the degree of freedom is reduced, so that the moisture in the wall cannot be sufficiently discharged.

Further, as shown in FIG. 5 , in the ventilation wall panel p provided with the window opening o, the air flow indicated by the arrow in FIG. 5 is obstructed by the lower side of the window opening o. In particular, it was not possible to prevent the effects of condensation in winter.

According to the present invention, the degree of freedom of air flow is based on mounting an exterior plate on a wall panel base using a fixture having a base portion forming a horizontal conduction path connecting the vertical air paths on both sides. It is an object of the present invention to provide a ventilation wall panel that can increase air permeability and improve air permeability, and can particularly prevent dew condensation in winter.

[0007]

In order to achieve the above object, a ventilation wall panel according to the present invention comprises a frame formed by extending a vertical frame member inside a peripheral frame formed by joining frame members in a rectangular shape. An interior plate attached to the inner surface facing indoors, a base plate attached to the outer surface facing the outdoors of the framework, and a heat insulating material to be loaded in a space formed by the frame material of the framework, the interior plate, and the base plate A wall panel base comprising: a wall panel base; and an exterior plate covering the wall panel base with vertical air passages 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 via fixing brackets. and wherein the fixing bracket is Rutotomoni provided a mounting piece for mounting engages the <br/> outer plate to the base portion forming a lateral guide passage communicating the longitudinal air path of the sides, front
That the length of the writing table portion is substantially equal to the height of the exterior plate.
Features.

[0008]

A vertical air path extending up and down on both sides of the fixing bracket is formed by attaching an exterior plate to the outer surface of the base plate of the wall panel base via a fixing bracket, and the vertical air path is formed by the fixing bracket. It is connected by the established horizontal conduction path. Therefore, 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 in the case of a ventilation wall panel having a window opening, dew condensation in winter can be prevented.
