[0002]

2. Description of the Related Art Conventionally, an exterior wall panel of a building such as a prefabricated house is constructed by fixing an exterior material such as cement to a steel frame material at a site. The exterior material is fixed to the panel frame by driving a fixing tool such as a screw or a nail from the surface side and fastening to the panel frame.

[0003]

However, in the case of the conventional outer wall panel, the exterior material is fixed to the framework at the site, and it is difficult to perform the installation at the site. Further, since the fixing tool is driven from the surface side of the exterior material, after the fixing operation, a putty filling process must be performed to hide the head of the fixing tool, resulting in poor workability and poor appearance.

In addition, the fixing member penetrates the exterior material, and particularly on the south side of the building, the exterior material becomes hot due to solar radiation on the outer wall surface, and thermal stress is generated between the exterior material and the panel frame. Cracks are generated, and there is a problem that rainwater infiltration and appearance are deteriorated. Also, if the fixing tool penetrates the exterior material and wind pressure is applied while the outer wall surface is wet with rainwater, rainwater will flood inside the exterior material and the fixing tool will rust,
There was also a problem that the decorative surface of the outer wall became dirty.

[0005] Further, the fixing tool penetrates the exterior material,
In a severe winter season, the fixing fixtures act as a thermal bridge, which causes dew condensation on the inside of the outer wall or the indoor surface, or impairs the function of the heat insulating material in the wall. An object of the present invention is to provide an outer wall panel which can improve workability on site, is excellent in workability, waterproofness, and appearance, and can prevent occurrence of dew condensation and rust of a fixing tool.
