[0016] Each embodiment of the present invention will be described below with reference to the drawings. The disclosure is merely an example, and any modifications that a person skilled in the art can easily make while maintaining the spirit of the invention are naturally included within the scope of the present invention. Furthermore, the drawings may be schematic in terms of the width, thickness, shape, etc. of each part compared to the actual embodiment for clarity of explanation, but these are merely examples and are not intended to limit the interpretation of the present invention. Furthermore, in this specification and each drawing, elements similar to those previously described with reference to the previous drawings are designated by the same reference numerals (or reference numerals with A, B, etc. suffixed thereto), and detailed descriptions may be omitted as appropriate. Furthermore, the letters "first" and "second" attached to each element are convenient labels used to distinguish each element and have no further meaning unless otherwise specified.

[0017] (First embodiment) A fire-resistant structure 1000 and a fire-resistant panel 100 according to one embodiment of the present invention will be described with reference to FIGS.

[0018] <1. Overview> FIG. 1 is a perspective view showing fireproof structures 1000-1 and 1000-2 according to one embodiment of the present invention. The fireproof structures 1000-1 and 1000-2 are applicable to compartment members inside or outside buildings such as logistics cold storage warehouses, clean rooms, hospitals, homes, production and livestock factories, commercial facilities, and office buildings. The fireproof structure 1000-1 includes a plurality of fireproof panels 100-1 to 100-16. In the following description, the fireproof structures 1000-1 and 1000-2 have the same structure except for their different locations. Therefore, when there is no need to distinguish between the fireproof structures 1000-1 and 1000-2, they will simply be referred to as the fireproof structure 1000. The fireproof panels 100-1 to 100-16 have the same structure except for their different locations. The same applies to each of the components of the fireproof structure 1000. Although FIG. 1 shows an example in which the fire-resistant panels 100-1 to 100-16 are laid horizontally, they may also be laid vertically.

[0019] The fireproof structure 1000 and the fireproof panel 100 are defined as having a first direction D1, a second direction D2 perpendicular to the first direction D1, and a third direction D3 perpendicular to the first direction D1 and the second direction D2. In the fireproof structure 1000, for example, the fireproof panels 100-1 to 100-8 are arranged side by side in the third direction D3. Adjacent fireproof panels 100 are joined at joints 102. The supports 104 are provided along the third direction D3. The fireproof panels 100-1 to 100-8 are fixed by the supports 104 and connectors 106-1 to 106-8. In the fireproof structure 1000, the surface on which the heads of the supports 104 and connectors 106 are provided is indoors or inside, and the opposite surface is outdoors or outside.

[0020] <2. Fireproof Panel Structure> FIG. 2 is an end view of a fire-resistant panel 100 according to one embodiment of the present invention. The fire-resistant panel 100 is constructed using a honeycomb material 112, non-combustible materials 114, 116, 118, and 122, reinforcing steel plates 124 and 126, and a decorative material 128. The honeycomb material 112 has a first surface 112a and a second surface 112b opposite the first surface 112a. The fire-resistant panel 100 has a non-combustible material 114 on the first surface 112a of the honeycomb material 112 and a non-combustible material 116 on the second surface 112b of the honeycomb material 112. The fire-resistant panel 100 is a so-called sandwich panel, in which the honeycomb material 112 is sandwiched between the non-combustible materials 114 and 116. The fire-resistant panel 100 includes a honeycomb material 112, non-combustible materials 114, 116, 118, 122, and a facing material 128 surrounding reinforcing steel plates 124, 126.

[0021] A non-combustible material 118 is provided on a first side surface 112c that is continuous with the first surface 112a of the honeycomb material 112. A non-combustible material 122 is provided on a second side surface 112d that is continuous with the first surface 112a of the honeycomb material 112. In other words, in the non-combustible material 114, the first side surface 114c that is adjacent to the first side surface 112c of the honeycomb material 112 is in contact with the non-combustible material 118. In the non-combustible material 116, the first side surface 116d that is adjacent to the second side surface 112d of the honeycomb material 112 is in contact with the non-combustible material 122. In the end view of the fire-resistant panel 100 shown in FIG. 3, the non-combustible material 118 and the non-combustible material 122 are provided in positions that are point-symmetrical with respect to the center of the honeycomb material 112.

[0022] A reinforcing steel plate 124 is provided on a first side surface 112c of the honeycomb material 112. The reinforcing steel plate 124 is provided so as to overlap the non-combustible material 118. The reinforcing steel plate 124 is sandwiched between the decorative material 128 and the non-combustible material 118. A reinforcing steel plate 126 is provided on a second side surface 112d of the honeycomb material 112. The reinforcing steel plate 126 is provided so as to overlap the non-combustible material 122. The reinforcing steel plate 126 is also sandwiched between the decorative material 128 and the non-combustible material 122. In the end view of the fire-resistant panel 100 shown in FIG. 3 , the reinforcing steel plate 124 and the reinforcing steel plate 126 are provided at positions that are point-symmetrical with respect to the center of the honeycomb material 112.

[0023] Openings 132 are provided in the decorative material 128 and the non-combustible material 118. The openings 132 are formed by overlapping the openings in the decorative material 128 and the non-combustible material 118. A plurality of openings 132 may be provided along the first direction D1. The openings 132 are openings through which connectors used to join adjacent fire-resistant panels are inserted. When the connectors are inserted, the heads of the connectors are fixed to the reinforcing steel plate 124, so it is preferable that no openings are provided in the reinforcing steel plate 124. In this embodiment, an example in which the openings 132 are provided in the decorative material 128 and the non-combustible material 118 will be described, but the present invention is not limited to this. Openings may also be provided in the decorative material 128 and the non-combustible material 122.

[0024] The fire-resistant panel 100 is a rectangular plate having a thickness T1, a width W1 (the width W1 is in a direction perpendicular to the paper surface and is therefore not shown in FIG. 2 ) and a height H1 that are greater than the thickness T1. The width W1 of the fire-resistant panel 100 corresponds to the width of the decorative material 128, and the height H1 of the fire-resistant panel 100 corresponds to the height of the decorative material 128. The thickness T1 of the fire-resistant panel 100 corresponds to the total thickness of the honeycomb material 112, the non-combustible materials 114 and 116, and the decorative material 128. Here, the width W1 is along the first direction D1, the height H1 is along the third direction D3, and the thickness T1 is along the second direction D2. The thickness T1 of the fire-resistant panel 100 is 50 mm to 200 mm, 70 mm to 120 mm, or 70 mm to 120 mm. The width W1 of the fire-resistant panel 100 is 1 m to 10 m, 1.5 m to 5 m, or 2 m to 5 m. The height H1 of the fire-resistant panel 100 is 50 cm to 200 cm, 50 cm to 150 cm, or 70 cm to 150 cm.

[0025] FIG. 3 is a perspective view illustrating an example of a honeycomb material 112. The honeycomb material 112 is used as a heat insulating material. The honeycomb material 112 does not need to have fire resistance, and any honeycomb material 112 can be used. Here, fire resistance refers to the ability to suppress the spread of a normal fire that occurs around a building. The honeycomb material 112 is made of various materials, such as non-combustible paper honeycomb material, cardboard, aluminum honeycomb material, or ceramic honeycomb material. When ceramic honeycomb material, aluminum honeycomb material, or non-combustible paper is used as the honeycomb material 112, 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 is 30 mm in this embodiment.

[0026] The shape of the cells in the cross section perpendicular to the cell extension direction of the honeycomb material 112 (thickness T2 direction of the honeycomb material 112) is not particularly limited, and may be, for example, a rectangle, a hexagon, an octagon, or a combination of these shapes. 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. The porosity of the honeycomb material 112 is, for example, 91% to 95%.

[0027] The honeycomb material 112 has a honeycomb structure, and more than 90% of its volume is air, which makes it possible to reduce the weight of the fire-resistant panel 100. The honeycomb structure also prevents air convection, improving the heat insulation of the fire-resistant panel 100. The honeycomb structure also provides high bending strength, and can increase strength against planar pressure.

[0028] The non-combustible materials 114, 116, 118, and 122 are used as fire-resistant covering materials. The non-combustible materials 114, 116, 118, and 122 are made of various materials, such as wood-based boards such as insulation boards, cellulose fiberboards, and wood wool cement boards, and inorganic boards such as gypsum boards and calcium silicate boards. The thickness of the non-combustible materials is 7 mm to 50 mm, 7 mm to 40 mm, or 9.5 mm to 30 mm. In this embodiment, two layers of 9.5 mm and 12.5 mm gypsum boards are stacked on top of each other.

[0029] The decorative material 128 is made of various materials, such as ceramic decorative material (ceramic), color steel plate, galvalume steel plate, and aluminum plate. The thickness of the decorative material is thinner 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, it is 9.5 mm. By using the decorative material 128, it is possible to prevent the fire-resistant panel 100 from being altered due to deformation, discoloration, deterioration, or the like. In addition, the design of the fire-resistant panel 100 is improved, such as by improving its appearance.

[0030] The decorative material 128 is curved to fit the shapes of the honeycomb material 112 and the non-combustible materials 114, 116, 118, and 122. The decorative material 128 has main body portions 128a and 128b, side surface portions 128c to 128f, and fitting portions 128g and 128h. The main body portion 128a is provided on the non-combustible materials 114 and 118 side, and the main body portion 128b is provided on the non-combustible materials 116 and 122 side. The side surface portion 128e is provided on a side surface of the non-combustible material 118, and the side surface portion 128f is provided on an end surface of the non-combustible material 122. In other words, the main body portion 128a is in contact with the non-combustible materials 114 and 118. The main body portion 128b is in contact with the non-combustible materials 116 and 122. The side surface portion 128c is provided on a first side surface 112c of the honeycomb material 112, and the side surface portion 128d is provided on a second side surface 112d of the honeycomb material 112. The fitting portion 128g is provided on the surface of the non-combustible material 118 opposite the main body portion 128a, and the fitting portion 128h is provided on the surface of the non-combustible material 122 opposite the main body portion 128b. In this embodiment, an example in which the decorative material 128 is continuous will be described, but this is not limiting and the decorative material 128 may be separated.

[0031] A reinforcing steel plate 124 is provided between the fitting portion 128g of the decorative material 128 and the non-combustible material 118, and a reinforcing steel plate 126 is provided between the fitting portion 128h of the decorative material 128 and the non-combustible material 122. 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 and 126 is greater than the thickness of the decorative material 128, and is 0.5 mm to 5 mm, 1.2 mm to 3 mm, or 1.6 mm to 2.3 mm. In this embodiment, the thickness of the reinforcing steel plates 124 and 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 fire-resistant panel 100, a width along the width W direction of the fire-resistant panel 100, and a height along the height direction of the fire-resistant panel 100. The width of the reinforcing steel plate 124 may be approximately the same as the width of the non-combustible material 114, and the width of the reinforcing steel plate 126 may be approximately the same as the width of the non-combustible material 116. By using the reinforcing steel plates 124, 126, the strength of the fire-resistant panel 100 can be improved. In addition, by using the reinforcing steel plates 124, 126, an appropriate thickness can be imparted to the connector 110.

[0032] An opening 132 penetrating the main body 128b of the decorative material 128 and the non-combustible material 118 may be provided in the main body 128a of the decorative material 128 and the non-combustible material 118. The opening 132 is a hole for inserting the connector 110 when joining adjacent fire-resistant panels 100 later. Note that the opening 132 does not have to be provided in the decorative material 128 and the reinforcing steel plate 124.

[0033] The honeycomb material 112 and the non-combustible materials 114, 116 are bonded together with an admixture. The non-combustible materials 114, 116 and the decorative material 128 are also bonded together with an admixture. As the admixture, a polyammonium phosphate-based fire retardant (applied to or impregnated in a wood-based board), a urethane-based, epoxy-based, sodium silicate-based, or water glass-based adhesive can be used.

[0034] In the fire-resistant panel 100, the pair of non-combustible materials 114, 116 are provided symmetrically with respect to the honeycomb material 112. It is preferable that the pair of non-combustible materials 114, 116 are provided so as to be made of the same material, have the same shape, and have the same thickness.

[0035] In the fire-resistant panel 100 according to one embodiment of the present invention, the non-combustible materials 114, 116 are inorganic boards, such as gypsum boards or calcium silicate boards. This allows for the use of various decorative materials, including wood-based materials, instead of the steel decorative materials typically used in sandwich panels. This allows for a change in the concept of sandwich panels and enables their application to buildings requiring diverse designs. The honeycomb material 112 can be made of ceramic, aluminum, non-combustible paper, cardboard, or other materials. In particular, when gypsum boards are used as the non-combustible materials 114, 116, the moisture (crystal water) contained in the gypsum boards is released during a fire, thereby suppressing the temperature rise of the fire-resistant panel 100. Furthermore, the non-combustible materials 114, 116 may be impregnated with a flame retardant, such as a phosphate-based agent, thereby further improving fire resistance.

[0036] According to the fire-resistant panel 100 of one embodiment of the present invention, when wood-based boards are used as the non-combustible materials 114, 116, it is preferable to use steel decorative materials such as color steel plates or galvalume steel plates, which can improve the fire resistance of the fire-resistant panel 100.

[0037] According to the fire-resistant panel 100 of one embodiment of the present invention, a honeycomb material 112 is used as the heat insulating material. The honeycomb material 112 is lighter than rock wool, which has traditionally been used as a heat insulating material. This allows the entire fire-resistant panel 100 to be lighter. Furthermore, while the honeycomb material 112 has the same thermal conductivity as rock wool, it is possible to reduce CO2 emissions during its manufacture. Furthermore, the wood-based boards used as the non-combustible materials 114, 116 can be manufactured by, for example, reusing thinned wood, which promotes the effective use of global resources.

[0038] As described above, various materials can be used as the honeycomb material 112 regardless of the heat resistance temperature, and the fire-resistant panel 100 having high fire resistance can be provided.

[0039] <3. Joint structure of fire-resistant panels> Fig. 4 is a cross-sectional view of a joining structure when a plurality of fire-resistant panels 100 according to one embodiment of the present invention are arranged and joined together. In the joining structure of the fire-resistant panels 100 shown in Fig. 4, the surface on which the head of the connector 110 is provided is the surface inside or facing the interior of the room.

[0040] The fire-resistant panels 100-1 and 100-2 are arranged in the third direction D3, with a thickness T1 and a width W1 directed in the first direction D1 and the second direction D2, and a height H1 directed in the third direction D3. The side surface 128c-1 of the fire-resistant panel 100-1 and the side surface 128f-2 of the fire-resistant panel 100-2 are arranged to face each other. The fitting portion 128g-1 of the fire-resistant panel 100-1 and the fitting portion 128h-2 of the fire-resistant panel 100-2 are arranged to face each other. The side surface 128e-1 of the fire-resistant panel 100-1 and the side surface 128d-2 of the fire-resistant panel 100-2 are arranged to face each other. A gasket rubber 120 is provided between the fire-resistant panels 100-1 and 100-2. The gasket rubber 120 can waterproof the gap (joint) between the fire-resistant panel 100-1 and the fire-resistant panel 100-2, and can also fill the gap between the fire-resistant panel 100-1 and the fire-resistant panel 100-2.

[0041] Furthermore, it is preferable that the length L1 in the third direction D3 of the region where the fire-resistant panels 100-1 and 100-2 face each other is 30 mm or more. If the length L1 is less than 30 mm, the fitting portion may open due to heat during a fire, which may lead to the spread of the fire.

[0042] The fitting portion 128g-1 of the fire-resistant panel 100-1 and the fitting portion 128h-2 of the fire-resistant panel 100-2 are mechanically and firmly connected by the connector 110 at the opening 132, with the gasket rubber 120 sandwiched between them. The connector 110 secures the reinforcing steel plate 124-1, fitting portion 128g-1, gasket rubber 120, fitting portion 128h-2, reinforcing steel plate 126-2, and non-combustible material 122-2 provided on the fire-resistant panel 100-1. The reinforcing steel plate 124-1 provided on the fire-resistant panel 100-1 is provided on the side through which the connector 110 is inserted (the head side of the connector 110). The reinforcing steel plate 126-2 provided on the fire-resistant panel 100-2 is provided on the side opposite the side through which the connector 110 is inserted (the tip side of the connector 110). This allows the connector 110 inserted through the fire-resistant panel 100-1 to be firmly fixed.

[0043] According to the joining structure of the fire-resistant panels 100-1, 100-2 according to one embodiment of the present invention, the above configuration makes it possible to suppress deformation of the decorative material 128 at the joint 102 even in the event of a fire. Therefore, the reinforcing steel plates 124-1 and 126-2 located on both sides of the gasket rubber 120 in the thickness direction can prevent opening or deformation in the thickness T1 direction of the decorative material 128 on the side where the fire has occurred.

[0044] Therefore, it is possible to prevent gaps caused by thermal deformation between the components of the joint 102 from being directly transmitted through the gaps to the honeycomb material 112, causing the honeycomb material 112 to burn and spread the fire, thereby preventing fire accidents in the fire-resistant structure 1000 using the fire-resistant panel 100.

[0045] <4. Fireproof Panel Manufacturing Method> Next, a method for manufacturing the fire-resistant panel 100 will be described with reference to FIG.

[0046] As shown in FIG. 5, a non-combustible material 114 is bonded to the first surface 112a of the honeycomb material 112, and a non-combustible material 116 is bonded to the second surface 112b. At this time, an admixture is applied to the first surface 112a and the second surface 112b of the honeycomb material 112. The non-combustible material 114 is bonded to the first surface 112a of the honeycomb material 112, and the non-combustible material 116 is bonded to the second surface 112b. The decorative material 128 is folded multiple times along the first direction D1. The honeycomb material 112 and the non-combustible materials 114 and 116 are fitted inside the decorative material 128 so that the non-combustible material 114 is provided on the main body portion 128a side and the non-combustible material 116 is provided on the main body portion 128b side.

[0047] Next, noncombustible material 118 and reinforcing steel plate 124 are overlapped and fitted into decorative material 128 so that noncombustible material 118 contacts main body portion 128a and reinforcing steel plate 124 contacts fitting portion 128g. Similarly, noncombustible material 122 and reinforcing steel plate 126 are overlapped and fitted into decorative material 128 so that noncombustible material 122 contacts main body portion 128b and reinforcing steel plate 126 contacts fitting portion 128h.

[0048] In this manner, the fire-resistant panel 100 shown in FIG. 2 can be manufactured.
