<4. Fireproof panel material>
Next, various materials used in the fire resistant panel 100 according to one embodiment of the present invention will be described.

The honeycomb material 102 is used as a heat insulating material. The honeycomb material 102 does not have to be fireproof, and honeycomb materials 102 of any material can be applied. Here, fire resistance refers to the ability to suppress the spread of fire caused by normal fires that occur around buildings. The honeycomb material 102 is composed of various materials such as, for example, non-combustible paper honeycomb material, cardboard, aluminum honeycomb material, or ceramic honeycomb material. For example, if a ceramic honeycomb material, an aluminum honeycomb material, or noncombustible paper is used as the honeycomb material 102, the fire resistance can be enhanced. The thickness of the honeycomb material is 15 mm to 50 mm, 20 mm to 50 mm, or 20 mm to 40 mm, and in this embodiment is 30 mm.

The shape of the cells in the cross section orthogonal to the cell extending direction (third direction D3) of the honeycomb material 102 is not particularly limited, and may be, for example, a quadrangle, hexagon, octagon, or a combination of these shapes. The cell size in the cross section of the honeycomb material 102 is 5 mm to 50 mm, 10 mm to 40 mm, or 25 mm to 35 mm, and is 30 mm in this embodiment. Moreover, the porosity of the honeycomb material 102 is, for example, 91% to 95%.

The honeycomb material 102 has a honeycomb structure, and 90% or more of the volume is air, so the weight of the fireproof panel 100 can be reduced. Moreover, since the honeycomb structure can prevent air convection, the heat insulation of the fireproof panel 100 can be improved. In addition, the honeycomb structure has high bending strength and can increase strength against planar pressure.

As the noncombustible boards 104, 106, 108, and 122, a material having noncombustible performance as a fireproof material, a small heat storage effect, and a large cooling effect is used. The noncombustible boards 104, 106, 108, and 122 are, for example, insulation boards, cellulose fiber boards, and wooden boards such as wood wool cement boards, concrete, cement mortar, gypsum boards, gypsum boards, fiber-containing gypsum boards, and Consists of various materials such as inorganic boards such as calcium silicate boards. As the noncombustible boards 104, 106, 108, 122, it is preferable to use a fireproof covering material having excellent strength and heat resistance. Fireproof coating materials include inorganic boards such as concrete, cement mortar, gypsum board, gypsum board, fiber-containing gypsum board, and calcium silicate board. In this embodiment, a case where calcium silicate boards are used as the noncombustible boards 104 and 106 and fiber-containing gypsum boards are used as the noncombustible boards 108 and 122 will be described. The thickness of the noncombustible boards 104, 106, 108, 122 is between 7 mm and 50 mm, between 7 mm and 40 mm, or between 9.5 mm and 30 mm.

As the channel steels 142 and 144, lightweight channel steel, C-shaped steel (lip channel steel) having a C shape is used. Channels and light channel steels are shapes that have a web and two flanges sandwiching the web. Also, the C-section steel has a shape having a web, two flanges sandwiching the web, and a lip at the tip of the flange. In this embodiment, channel steels 142 and 144 are shown in the form of channel steels without lips. The channel steels 142, 144 are composed of various materials such as, for example, alloys such as aluminum, stainless steel, and the like.

The recessed fitting 146 is a channel steel or setting block. When channel steel is used as the concave fitting member 146, the same material as the channel steels 142, 144 is used.

The decorative materials 114 and 116 are made of various materials such as, for example, wood-based materials, ceramic-based decorative materials (ceramic-based), color steel plates, galvanium steel plates, aluminum plates, or wallpaper. The thickness of the decorative materials 114, 116 is thinner than the thickness of the noncombustible boards 104, 106, and is 4 mm to 15 mm, 5 mm to 12 mm, or 8 mm to 12 mm, and in this embodiment, 9.5 mm.

In the fireproof panel 100 , a pair of noncombustible boards 104 and 106 are provided so as to be symmetrical with respect to the honeycomb material 102 . The pair of noncombustible boards 104 and 106 are preferably made of the same material, have the same shape, and have the same thickness.

The fireproof panel 100 according to one embodiment of the present invention has a structure in which the honeycomb material 102 is sandwiched between the noncombustible boards 108 and 112 and the noncombustible boards 108 and 112 are sandwiched between the noncombustible boards 104 and 106 . As a result, the laminated structure of the noncombustible boards 108, 112 and the noncombustible boards 104, 106 can improve the fire resistance. In addition, the bending strength of the fireproof panel 100 can be improved. As a result, it becomes possible to use various decorative materials such as paper materials in addition to wood-based materials instead of steel decorative materials that have been used in conventional sandwich panels, and the appearance of the fireproof panel 100 is improved. The design of the product is improved. Furthermore, the concept of sandwich panel design can be changed, making it possible to apply it to buildings that require a variety of designs.

In this embodiment, the noncombustible boards 104 and 106 are calcium silicate boards, and the noncombustible boards 108 and 112 are fiber-mixed gypsum boards. Calcium silicate boards have the effect of allowing the temperature to take effect quickly after being heated in the event of a fire. In addition, the fiber-containing gypsum board has the effect of suppressing the temperature rise of the fire-resistant panel 100 by releasing moisture (crystallization water) when heated in the event of a fire. With such a configuration, it is possible to ensure sufficient fire resistance to meet the fire resistance requirements of the fire resistance panel 100 .

According to the fireproof panel 100 of one embodiment of the present invention, the honeycomb material 102 is used as the heat insulating material. The honeycomb material 102 can be made lighter than rock wool, which has been conventionally used as a heat insulating material. Therefore, the weight of the entire fireproof panel 100 can be reduced. In addition, while having the same thermal conductivity as rock wool, it is possible to reduce the amount of CO ₂ emitted during its production. According to the fireproof panel 100 according to one embodiment of the present invention, various materials can be used as the honeycomb material 102 regardless of the heat resistance temperature.

In addition, when gypsum boards are used as the non-combustible boards 104 and 106, the moisture (water of crystallization) contained in the gypsum boards is released in the event of a fire, thereby suppressing the temperature rise of the fireproof panel 100. Also, the noncombustible boards 104 and 106 may be impregnated with a flame retardant such as a phosphoric acid chemical. Thereby, fireproof performance can be improved more.
