DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building provided with a structural panel and a ventilation layer, and more particularly, to a structural panel mainly constituting a structural wall of a building with a ventilation method, wherein the inside of the panel is provided. The present invention relates to a structural panel capable of reliably preventing dew condensation in the above and having a sufficient proof stress, and capable of dramatically improving workability, and a building having a wall constituting portion formed by the structural panel.

[0002]

2. Description of the Related Art In a wooden or steel-framed building,
Since it can be constructed into a free shape at relatively low cost and can exhibit excellent proof strength, a method of arranging a structural panel between columns to constitute a structural wall (hereinafter referred to as a "framed panel method") )) Is spreading as a kind of new conventional construction method. In buildings using the frame panel method, a ventilation layer method centering around the wall is used in order to achieve high airtightness and high heat insulation and to prevent the inside of the frame from becoming wet, as in the case of the conventional method. Various studies have been made.

[0003] In a building of the frame panel construction method, for example, a structural panel is composed of a structural panel material attached to the outdoor side of a vertical and horizontal frame and an interior material such as a gypsum board attached to the indoor side of the frame. And a heat insulating material such as glass wool disposed between the structural face material and the interior material, and a ventilation space formed between the structural face material and the heat insulating material. The ventilation layer is formed between the structural face material and the exterior material disposed outside the room, and the structural face material of the structural panel includes the above-described ventilation space and the outdoor-side breathable layer. And a small hole for making the continuation. Also, on the indoor side of the heat insulating material, for example, a moisture-proof material such as a polyethylene film is stretched in order to prevent water vapor in the air in the heated room from penetrating into the wall, In order to prevent the members from getting wet, a waterproof sheet is stretched on the outdoor side of the structural face material.

[0004]

In a building using the above-mentioned frame panel method, the necessary strength must be ensured by the structural panel material of the structural panel, so that the size of the ventilation hole is sufficiently large. It is difficult in practice, and in fact, the ventilation layer on the outdoor side does not function sufficiently with respect to the ventilation space inside the wall. As a result, for example, when the room temperature is lower than the outside air temperature due to cooling in summer, the water vapor contained in the air equivalent to the outside in the heat insulating material is condensed on the outdoor surface of the moistureproof material or inside the heat insulating material. This may cause deterioration of the performance of the heat insulating material and decay of the wood. Also, structural panels are originally intended for efficient construction, and there is a demand for a structure that can further enhance the workability.

SUMMARY OF THE INVENTION The present invention has been made to improve the ventilation state and the workability while maintaining the strength of the wall constituting portion as a structural wall.
