The present invention relates to a siding board (hereinafter simply referred to as a board) that can pass the so-called box test, which is an additional test to the semi-flammability test (JIS-A-1321). Recently, with the tightening of fire prevention regulations, organic polymer foams such as polyurethane foam, polyisocyanurate foam, and composite boards using these foams, such as composite boards made by sandwiching the foam with thin metal sheets and paper, have become compliant. Even if it passed the nonflammability test, it could not pass the additional test. The biggest cause was that the total calorific value greatly exceeded the standard value. Moreover, the main cause of this is the above-mentioned foam near the connection between the boards, or foam mixed with inorganic material, which is burned by hot air and flame, and the hot air gradually penetrates into the core material. It was because I did it. In order to eliminate these drawbacks, the present invention uses a nonflammable spacer on the back side of the connection part of the board and a fire retardant filled in the tunnel-shaped space to prevent flames and hot air from entering the interior, and also prevents the core material itself from entering. We propose a board that can pass both of the above tests by using a molded flame retardant foam. Below, the board according to the present invention will be described in detail using the drawings. FIG. 1 is a perspective view showing a typical example of the board, in which 1 is a surface material, 15
17 is a core material, 17 is a tunnel-like space, 18 is a fire retardant,
19 is a nonflammable spacer. To explain further, the surface material 1 is formed from a thin metal plate by roll forming, pressing, or (not shown) extrusion and drawing, as shown in FIG. That is, the surface material 1 has a rectangular decorative surface 2 and side walls 3 and 4 with both side edges bent inward or raised.
A male connecting portion 8 formed from a main body 5 having a concave cross section, an insertion edge 6 projecting outward from the lower end of the side wall 3, and a tongue piece 7 provided at the tip thereof, An insertion groove 9 formed inwardly in a U-shape, an extension part 11 projecting outward from the lower edge 10 of the insertion groove 9, and a protrusion 12 and a tongue at the tip of the extension part 11 if necessary on the way. It is composed of a female type connecting part 14 provided with a piece 13. Further, the core material 15 is a molded body that is inserted into and filled into the concave portion 5' of the main body 5 and functions as a fireproof and heat insulating layer. That is, the cross section of the core material 15 is a rectangle in which one side is the width W 1 between the side wall 3 and the back surface of the insertion groove 9, and the thickness is T which is larger than the height h 1 of the side wall 3 by Δt. Moreover, it is an elongated body having a notch 16 cut out at one corner on the side wall 3 side with a width of ΔW and a height of Δt. Further, the Δt portion will be referred to as a bulging portion 15' for convenience. Note that there is a difference between Δt and t (dimension from the lower edge 10 to the back surface of the core material 15) by approximately the opening height Δh of the insertion groove 9. To explain specifically, the core material 15 has the ability to pass a quasi-noncombustible test as a fire retardant,
It is made of a closed-cell foam structure with a density of 28 to 50 kg/m 3 , such as phenol foam, fire-retardant foam, etc. The tunnel-shaped space 17 is a space surrounded by at least the back surface of the side wall 4 and the side surface 15a of the core material 15 (the figure shows a space surrounded by the decorative surface 2 and the back surface of the insertion groove 9 in addition to the above). The space mainly functions as a space for filling the fire retardant 18 that directly enhances the fire retardant properties of the joint, and also serves to facilitate the formation of the core material 15. The fire retardant 18 is applied to the decorative surface 2 and the joints 20 between the boards (third
(shown in the figure) is exposed to high heat, this part is gradually cooled and foamed, and the high heat forms between the core material 15 and the surface material 1 , and between the surface material 1 and the non-combustible spacer 19. This method fills the voids between the layers with an inorganic foam layer to suppress heat conduction to deeper layers.
is impregnated into the nonflammable spacer 19 to further reduce the thermal conductivity of the nonflammable spacer 19. Specific examples thereof include borax (pentahydrate, decahydrate), sodium metaborate, sodium metasilicate, compositions consisting of borax, boric acid, and water glass, compositions consisting of borax, caustic soda, and water, and the like. A composition in which a substance is mixed with sodium phosphate and sodium polyphosphate, a foamable inorganic material made of a mixture, and a tunnel-like space 17
Binder to be molded for filling, e.g.
It is molded into a predetermined shape from PVA, CMC, calcium carbonate, and a string-like material made of open-cell organic foam, inorganic foam, or inorganic fiber used as a reinforcing material if necessary. In addition, the non-combustible spacer 19 provides the female connecting portion 14 of the board with fire protection and stable shape retention when the board is installed. It is made of one type of material, such as concrete, a ceramic-based inorganic material that is easy to nail, or a foamed inorganic material. Furthermore, the thickness t of the nonflammable spacer 19 is approximately the same as the height from the back surface of the decorative surface 2 to the lower edge 10, and the width W2 is such that it covers at least the lower edge 10 and the back surface of the extension part 11. The length is the same as that of the surface material 1 . Next, examples will be described. First, the surface material 1 is a colored steel plate (thickness 0.27
mm) are W 1 = 286 mm, h 1 = 8 mm, h 2 = 10.5 mm, and the width W 3 from the innermost part of the insertion groove 9 to the tongue piece 13 is 34 mm. The core material 15 is a phenol foam with T=24.5 mm, width the same as W1 , Δt=17 mm, and density 30 Kg/m 3 . The fire retardant 18 is a reinforcing material made of alkali-resistant glass fiber mat with a density of 100 kg/m 3 formed into a string shape with an angular cross section slightly smaller than the tunnel-like space 17, and the foamable inorganic material is sodium metaborate. It is melted and impregnated with the above string to a density of 300 kg/m 3 and hardened.
After molding the surface material 1 , this is inserted and integrated. Furthermore, as the nonflammable spacer 19,
A board as shown in FIG. 1 was manufactured using a board with W 2 =34 mm, thickness t = 14.5 mm, and length 3030 mm. Although not shown in the drawings, at least a portion of the adhesive is used to integrate the surface material 1 , the core material 15, and the nonflammable spacer 19. In addition, as a comparative example, the surface material had the same shape and material as the example, the back surface of the surface material 1 as a core material was completely filled with phenol foam by molding, and the cross-sectional outline was the same shape as the example. It is something. Therefore, when both test pieces were subjected to a surface test and an additional test (box test) according to JIS-A-1321, the results were as shown in the table below.

What has been described above is an embodiment of the board according to the present invention, in which the surface material 1 is formed as shown in FIGS. 4a to 4d, and the core material 15 is formed as shown in FIGS. 6a and b to form a non-combustible spacer 19.
It is also possible to form a board as shown in FIGS. 7A to 7C, and to form a board in which these are combined, for example, as shown in FIGS. 7A to 7C. That is, FIG. 4a shows a surface material 1 in which the lower end of the side wall 3 is bent inward to form a protrusion 3a to better sandwich the core material 15, and FIG. 4b shows a surface material 1 in which the side wall 3 is inclined. Figure c shows the surface material 1 with tongue pieces 13 formed as shown in the figure, and figure d shows the surface material 1 with ribs 2a formed on the decorative surface 2. In addition, FIG. 5a shows a core material with a sheet-like material 21 provided on one side of the core material 15, and FIG. 5b shows a core material with sheet-like materials 21 provided on both sides of the core material 15.
Figure c shows a core material 15 in which the entire back surface of the core material 15 is covered with a sheet material 21, Figure d shows a core material 15 with the side surface 15a formed as shown, and Figure e shows a core material 15. A core material 1 whose outer periphery is covered with a sheet material 21
It is 5. Furthermore, FIG. 6a shows the nonflammable spacer 1
The nonflammable spacer 19 whose side surface in contact with the core material 15 of No. 9 is inclined, and the nonflammable spacer 19 shown in FIG. In addition, FIG. 7a shows a board in which the exposed back surface of the board is covered with a sheet-like material 21, FIG. The figure shows a board in which the core material 15 and noncombustible spacers 19 are formed as shown in the figure. The sheet-like material 21 may be, for example, kraft paper, asbestos paper, gypsum paper, glass fiber, etc., non-woven fabric such as synthetic resin, metal foil (Al, Pb), foam sheet (3 to 4 mm), asphalt felt, etc. Laminated with seeds or more,
Alternatively, to obtain shape retention at high temperatures, sandwich the wire mesh on both sides with sheet-like materials such as those described above.
The sheet-like material 21 or the like is formed by molding this, and the sheet-like material 21 is a molded product or a material that can be simultaneously molded in a mold when forming a foam. Furthermore, as shown in FIG. 7c, a fireproof joint material 22 that forms an inorganic foam layer under high heat can be planted in the insertion groove 9. Although not shown, one or more of borates, silicates, fibrous materials, inorganic porous particles, etc. can be added or mixed into the core material 15 in the foam. Specific examples include borax, sodium metaborate, sodium metasilicate, pearlite grains, vermiculite, and shirasu balloons. As mentioned above, according to the board according to the present invention,
The joints, which are the weakest point thermally, and especially the female joints that maintain the board in place, are fixed using fire retardant and non-combustible spacers, so the boards are securely fixed without deforming under high heat. , flame from the joint,
It has the feature of suppressing the intrusion of hot air. In addition, the core material carbonizes under high heat, but the voids formed during carbonization between the surface material, the core material, the back of the female joint, and the nonflammable spacer are cooled with a fire retardant, and these voids are filled with inorganic material. Since it is closed with a foam layer, heat conduction is reduced, and since the core material is a molded body, the total heat generation amount and heat generation rate are small, and are characterized by being within the acceptance criteria of the box test. In addition, the board was installed on the back of the extension with a dimensionally stable and incombustible spacer that lacks elasticity, making it easy to drive nails, and without causing any wavy distortion in the extension. It has the feature that it is easy to insert the rim.
Furthermore, there is an advantage that the thickness of the core material and the thickness of the nonflammable spacer can be arbitrarily selected depending on the purpose, regardless of the material of the surface material. Furthermore, the board in a steady state has excellent heat insulation properties, and has a beautiful appearance by suppressing oil cans that occur on the decorative surface.
