Description

  The present invention relates to a building material panel. More specifically, the present invention relates to a building material panel in which a surface material and a back surface material are attached to both sides of a frame body composed of an upper and lower vertical frame and a left and right horizontal frame.

  Conventionally, for exteriors and interiors of apartment houses such as detached houses and condominiums, a surface material is pasted or fixed on the front side of a frame body composed of upper and lower vertical frames and left and right horizontal frames, and a rear surface material is pasted or fixed on the back side. Building material panels are used. Usually, a heat insulating material such as glass wool or rock wool is filled between the surface material and the back surface material, and when the surface material is disposed indoors and the back material is disposed outside the room, a high outdoor temperature is generated in summer. In winter, it prevents cold and prevents problems such as dew condensation in the room and keeps the indoor living environment in good condition throughout the seasons.

  On the other hand, when using the building material panel described above for a wooden building, fire resistance is also required. Therefore, Japanese Patent Application Laid-Open No. 2007-039915 discloses a wood base made of a wood material, a first gypsum board attached to the indoor side of the wooden base, and an aluminum layer attached to the indoor side of the first gypsum board. A fireproof structure of a wooden building including a glass fiber sheet with an aluminum layer and a second gypsum board attached to the indoor side of the glass fiber sheet with an aluminum layer, and at least one surface of the glass fiber sheet with an aluminum layer is aluminum A fireproof structure of a wooden building made of a glass fiber sheet covered with foil has been proposed.

And the said glass fiber sheet with an aluminum layer is a weight of 130-170 g / m < ² >, thickness is 0.13-0.17 mm, for example, and the thickness of aluminum foil is 0.01-0.03 mm Is stated to be preferred.

  As an example of the fireproof structure, there is described a form in which a glass wool heat insulating plate is installed between two fireproof structures as shown in FIG. 2 of the Japanese Unexamined Patent Publication No. 2007-039915. It is stated that the fire-resistant structure can easily have an excellent radiation insulation function and fire-resistant performance.

  However, as schematically shown in FIG. 5 of the present application, for example, when a building material panel E in which a space formed by the frame W and the front surface material 1 and the back surface material 2 is filled with the heat insulating material 3 is used for the exterior of the building. Even if the building material panel E has a symmetrical structure in the thickness direction, there is a problem that warping occurs when the environment such as the temperature difference or the humidity difference between the room and the outside is different.

  For example, when the outdoor temperature is about 5 ° C. in the winter and the room temperature is kept at about 20 ° C., the indoor surface material 1 has a tensile stress due to heating heat and humidity as shown in FIG. Work and stretch. On the other hand, the back material 2 on the outdoor side contracts due to compressive stress due to a low outside air temperature or low humidity in winter. And the curvature which becomes convex in a room occurs.
