DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a building panel according to the present invention will be described in detail with reference to the drawings. FIG. 1A is a cross-sectional view showing a typical example of the building panel A, and FIG. 1B is an enlarged view showing a portion of FIG. It is a building panel A sandwiched with a core material 3 made of a synthetic resin foam made of a synthetic resin, and a fireproof sheet B is disposed at least on the back surface side (boundary surface with the core material 3) of the surface material 1 It is.
[0006]
Surface material 1 and back surface material 2 are thin metal plates such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galvalume steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (control) Corrugated steel sheets, etc.), vinyl chloride resin, polycarbonate resin, etc. (including color plates coated with various colors of course), etc., molded into various shapes by roll molding, press molding, extrusion molding, etc., or inorganic materials Formed into various arbitrary shapes by extrusion molding, press molding, autoclave ripening, etc., as well as aluminum evaporated paper, asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic Resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc. Those that have been laminated species, or two or more, or waterproofing, is made of a flame-retardant treated sheet.
[0007]
The core material 3 is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., for example, a stock solution of resol type phenol, A curing agent and a foaming agent are mixed, discharged onto the back surface side of the surface material 1 or the back material 2, and heated to react, foam and cure. In addition, the core material 3 includes lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool, carbon fiber, Graphite etc. can be mixed to improve fire resistance and fire resistance.
[0008]
The fireproof sheet B is integrally laminated at least on the back surface side (boundary surface with the core material 3) of the surface material 1, and mainly prevents the building panel A, improves fire resistance, and flatness of the surface material 1. It functions as an improvement, adhesive reinforcement between the surface material 1 and the core material 3, and a strengthening agent for the mechanical strength of the building panel A as a whole.
[0009]
For example, as shown in FIG. 2, the refractory sheet B includes a rubber-based main material 4 and a sheet-like material 5 integrally laminated on at least one surface of the main material 4. Further, as shown in FIG. 1B, the main material 4 contains a heat-foamable carbon component 6 using the main material 4 as a binder.
[0010]
The main member 4 of rubber, for example, as various synthetic rubbers and natural rubber, made butyl rubber, polyethylene rubber, polybutene rubber, EVA, styrene-butadiene, high styrene rubber, of one or more such styrenic et elastomer, refractory sheet A certain degree of flexibility, plasticity, and elasticity are added to B, and it can be formed into a coiled or coiled shape, resulting in a fire-resistant sheet B that is very easy to handle and easy to handle. Furthermore, by adopting a rubber system as the main material 4, the main material 4 and the surface material 1 and the sheet-like material 5 to be described later can be bonded by utilizing the self-adhesiveness of the main material 4 itself, and a separate adhesive or the like can be used. Even if it is not used, it can be firmly and easily bonded. Of course, the surface material 1 and the refractory sheet B can be firmly bonded separately using an adhesive.
[0011]
Moreover, as the carbon component 6 mixed in the inside of the main material 4, it consists of carbon compounds, such as a graphite and carbon black, for example, and when it receives heat, it carbonizes and foams, and forms a heat insulation layer. , Which prevents heat conduction. The expansion ratio of the carbon component 6 is about 5 to 80 times.
[0012]
The sheet-like material 5 mainly improves the adhesiveness between the core material 3 and the fireproof sheet B, and is formed on one surface of the main material 4, that is, the surface laminated with the core material 3. As the material, for example, polyester-based, nylon-based, boron-based, carbon-based, alumina-based, silicon carbide-based, aramid-based, glass fiber-based nonwoven fabric, aluminum hydroxide sheet, rock wool sheet, ceramic sheet, carbonic acid It consists of 1 or more types, such as a calcium sheet, a calcium silicate sheet, a kraft paper, a metal foil sheet, a synthetic resin sheet, a fiber-type cloth sheet.

3 (a) to 3 (c) are examples showing the overall shape of the building panel A, FIG. 3 (a) is a perspective view thereof, and FIGS. 3 (b) and 3 (c) are views of FIG. 3 (a). This corresponds to the cross-sectional view of the roll line.
[0014]
That is, the decorative surface 7 in which the central portion of the surface material 1 is protruded in a square convex shape and the connecting tongue piece 8 are formed, and the connection between the building panels A is connected to the connecting tongue piece on the four side pieces. 8 is performed by superimposing them.
[0015]
3B is an example in which the refractory sheet B is also laminated on the lower portion of the connecting tongue piece 8 of the surface material 1, and FIG. 3C is an architectural view in which the refractory sheet B in the lower portion of the connecting tongue piece 8 is cut off. It is an example of panel A.
[0016]
Furthermore, in order to confirm fire prevention performance, an aluminum steel plate having a thickness of 0.5 mm is used as the surface material 1, an isocyanurate foam having a density of 60 kg / cubic meter is used as the core material 3, and a steel plate having a thickness of 0.27 mm is used as the back material 2. A fireproof structure test was performed using a building panel A as shown in FIG.
[0017]
As a result, the maximum back surface temperature of the building panel A main body was 150 ° C., the maximum back surface temperature of the joint was 100 ° C., and the afterflame time was 0 seconds, and the results were acceptable.
[0018]
5A and 5B are explanatory views showing an example in which holes are formed in the refractory sheet B. FIG. 5A is a perforated shape, and FIG. 5B is a cylindrical hole 9 formed. It is a thing. The hole 9 promotes the flexibility, plasticity, and elasticity of the fireproof sheet B, makes it easier to handle, and functions as a space when the carbon component 6 is foamed in the event of a fire, etc. It is useful for forming a heat-resistant layer.
[0019]
The depth of the hole 9 is as shown in FIG. 6 (b) until the middle of the main material 4 as shown in FIG. 6 (a), which is a sectional view of the ha-ha part in FIG. 5 (b). The depth can be set to the boundary between the main material 4 and the sheet-like object 5 or as shown in FIG. 6C.
