2. Description of the Related Art In a wooden or steel-framed building,
A method of constructing a wall by arranging a structural panel between columns (hereinafter, referred to as a "frame panel method") because it can be constructed in a free shape at a relatively low cost and exhibit excellent strength. ) Is spreading as a kind of new conventional construction method. The structural panel is formed, for example, by attaching a heat insulating material such as glass wool to the surface of a structural face material that functions as a bracing, and is excellent in workability as compared with the conventional construction method. Also, in buildings with the framed panel construction method, a ventilation layer around the wall is used, as in the case of the conventional construction method, in order to achieve high airtightness and high heat insulation and to prevent the inside of the frame from becoming wet. The construction method is adopted. The ventilation layer method is a method of providing a ventilation layer for introducing air into a wall.

When a structural panel is used for the ventilation layer construction method, an exterior material is attached to the outside of the structural panel via a vertical trunk edge, and a gap between the structural panel and the exterior material functions as a ventilation layer. In addition, various interior materials are installed on the indoor side of the structural panel. However, in order to prevent water vapor in the room air from permeating into the wall during heating or the like, usually, the exterior side of the interior material is installed. A moisture-proof material such as a polyethylene film is stretched on the surface, that is, the indoor surface of the structural panel.

A) has a structure in which the structural face material (11) is directly fixed to the frame material such as the base (31), the pillar (31), and the body (32), so that sufficient strength can be exhibited. Further, since the internal ventilation space (14) communicating with the ventilation layer (7) by the through hole (16) is provided, internal dew condensation can be reliably prevented. Moreover, the heat insulating material (1
2) The wall structure can be constructed by simply fitting the structural member (11) and fixing the structural surface material (11), and there is no need to stretch a moisture-proof material such as a polyethylene film on the indoor side unlike the conventional method. Since the interior construction can be performed immediately, the workability can be dramatically improved.
