FIG. 3 is a perspective view illustrating an example of the honeycomb material 112. FIG. The honeycomb material 112 is used as a heat insulator. The honeycomb material 112 does not have to be fireproof, and honeycomb material 112 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 112 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 112, the fire resistance can be improved. 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 direction in which the cells of the honeycomb material 112 extend (thickness T2 direction of the honeycomb material 112) is not particularly limited, and may be, for example, a square, a hexagon, an octagon, or a combination of these shapes. good too. The cell size d in the cross section of the honeycomb material 112 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 112 is, for example, 91% to 95%.

The honeycomb material 112 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.

Non-combustible materials 114, 116, 118, 122 are used as refractory coatings. The non-combustible materials 114, 116, 118, 122 are, for example, various materials such as insulation boards, cellulose fiber boards, wooden boards such as wood wool cement boards, and inorganic boards such as gypsum boards and calcium silicate boards. consists of The thickness of the incombustible material is 7 mm to 50 mm, 7 mm to 40 mm, or 9.5 mm to 30 mm, and in this embodiment, two gypsum boards of 9.5 mm and 12.5 mm are stacked.

The decorative material 128 is made of various materials such as, for example, a ceramic-based decorative material (ceramic-based), a color steel plate, a galvanium steel plate, and an aluminum plate. The thickness of the facing material is less than the thickness of the non-combustible materials 114, 116, and is 4 mm to 15 mm, 5 mm to 12 mm, or 8 mm to 12 mm, and in this embodiment is 9.5 mm. By using the decorative material 128, it is possible to suppress deterioration of the fireproof panel 100 due to deformation, discoloration, deterioration, or the like. In addition, the appearance of the fireproof panel 100 is improved, and the design is improved.

The main body portion 128a is provided on the non-combustible materials 114, 118 side, and the main body portion 128b is provided on the non-combustible materials 116, 122 side. The side portion 128 e is provided on the side surface of the noncombustible material 118 , and the side portion 128 f is provided on the end surface of the noncombustible material 122 . In other words, body portion 128 a contacts non-combustible material 114 and non-combustible material 118 . Body portion 128 b contacts non-combustible material 116 and non-combustible material 122 . The side portion 128 c is provided on the first side surface 112 c of the honeycomb material 112 , and the side portion 128 d is provided on the second side surface 112 d of the honeycomb material 112 . The fitting portion 128g is provided on the surface of the body portion 128a opposite to the nonflammable material 118, and the fitting portion 128h is provided on the surface of the body portion 128b opposite to the nonflammable material 122. be done. In this embodiment, an example in which the cosmetic material 128 is continuous will be described, but the present invention is not limited to this, and may be separated.

A reinforcing steel plate 124 is provided between the fitting portion 128g of the decorative material 128 and the noncombustible material 118, and a reinforcing steel plate 124 is provided between the fitting portion 128h of the decorative material 128 and the noncombustible material 122. A steel plate 126 is provided. Various materials such as iron plates can be used for the reinforcing steel plates 124 and 126 . The thickness of the reinforcing steel plates 124, 126 is greater than the thickness of the facing material 128 and is between 0.5 mm and 5 mm, between 1.2 mm and 3 mm, or between 1.6 mm and 2.3 mm. In this embodiment, the thickness of the reinforcing steel plates 124, 126 is 1.6 mm. The reinforcing steel plates 124 and 126 are rectangular plates having a thickness along the thickness T1 direction of the fireproof panel 100, a width along the width W direction of the fireproof panel 100, and a height along the height direction of the fireproof panel 100. shape. The width of the reinforcing steel plate 124 may be substantially the same as the width of the non-combustible material 114 and the width of the reinforcing steel plate 126 may be substantially the same as the width of the non-combustible material 116 . By using the reinforcing steel plates 124 and 126, the strength of the fireproof panel 100 can be improved. In addition, by using the reinforcing steel plates 124 and 126, an appropriate thickness can be given to the coupler 110. As shown in FIG.

The body portion 128 a of the decorative material 128 and the non-combustible material 118 may be provided with an opening 132 passing through the body portion 128 b of the decorative material 128 and the non-combustible material 116 . The openings 132 are holes through which the connectors 110 are inserted when joining the adjacent fireproof panels 100 later. Note that the decorative member 128 and the reinforcing steel plate 124 may not have the openings 132 .

The honeycomb material 112 and the non-combustible materials 114, 116 are adhered by an admixture. The nonflammable materials 114, 116 and the decorative material 128 are adhered by an admixture. As the admixture, an ammonium polyphosphate-based (coated or impregnated on a wooden board) non-flammable agent, a urethane-based, an epoxy-based, a sodium silicate-based, or a water glass-based adhesive can be used.

In fire resistant panel 100 , a pair of non-combustible materials 114 , 116 are provided symmetrically with respect to honeycomb material 112 . It is preferable that the pair of incombustible materials 114 and 116 are made of the same material, have the same shape, and have the same thickness.

According to the fire-resistant panel 100 in one embodiment of the present invention, the non-combustible materials 114, 116 are inorganic boards such as gypsum boards or calcium silicate boards, for example. This makes it possible to use any decorative material other than a wood-based material in place of the steel decorative material used in the sandwich panel. As a result, it is possible to change the image concept of sandwich panels and apply them to buildings that require a variety of designs. As the honeycomb material 112, materials such as ceramic material, aluminum material, non-combustible paper, or cardboard can be used. In particular, when gypsum boards are used as the incombustible materials 114 and 116, 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 nonflammable materials 114 and 116 may be impregnated with a flame retardant such as a phosphoric acid-based chemical. Thereby, fireproof performance can be improved more.

According to the fire-resistant panel 100 in one embodiment of the present invention, when wood-based boards are used as the non-combustible materials 114 and 116, it is preferable to use steel decorative materials such as colored steel plates or galvanized steel plates. Thereby, the fire resistance of the fire-resistant panel 100 can be improved.

According to the fireproof panel 100 of one embodiment of the present invention, the honeycomb material 112 is used as the heat insulating material. The honeycomb material 112 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. In addition, the wood-based boards used as the non-combustible materials 114 and 116 can be manufactured, for example, by reusing thinned wood, which promotes the effective use of resources on earth.

As described above, various materials can be used as the honeycomb material 112 regardless of the heat resistance temperature, and the fireproof panel 100 with high fireproof performance can be provided.

As a result, the connector 110 inserted from the fireproof panel 100-1 can be firmly fixed.

According to the joint structure of the fireproof panels 100-1 and 100-2 according to the embodiment of the present invention, even in the event of a fire, the decorative material 128 at the joint 102 can be Deformation can be suppressed. Therefore, the reinforcement steel plates 124-1 and the reinforcement steel plates 126-2 positioned on both sides in the thickness direction of the gasket rubber 120 prevent the decorative material 128 on the fire side from opening or deforming in the thickness T1 direction. be able to.

Therefore, it is possible to prevent the honeycomb material 112 from burning and spreading due to the heat or flame being directly transmitted to the honeycomb material 112 through the gap caused by thermal deformation between the constituent members of the joint 102 . Thereby, the fire accident in the fire-resistant structure 1000 using the fire-resistant panel 100 can be suppressed.
