BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a building panel according to the present invention. That is, as shown in FIG. 1, the building panel A has a front material 1 and a back material 2.
For example, a building panel A in which a core material 3 made of a synthetic resin foam mainly made of a phenol resin is sandwiched.

As an example of the overall shape of the building panel A, as shown in FIG. 1, a surface material 1 made of a long metal thin plate is used.
A core member 3 is sandwiched between the base member 3 and the back member 2, and a male connecting part 4 formed at one end in the width direction and a female connecting part 5 formed at the other end.
It is formed from In FIG. 2A, α is a frame, β is a fixture, and γ is a waterproof sheet such as asphalt felt.

The surface material 1 is made of a metal sheet, for example, iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy-plated steel sheet, galvalume steel sheet, enameled steel sheet, clad steel sheet, laminated steel sheet (PVC steel sheet, etc.), sandwich steel sheet (vibration damping). Rolled, pressed, extruded, etc., into a variety of shapes, such as rolls, presses, extrusions, etc., or inorganic materials. It is formed into various arbitrary shapes by extrusion molding, press molding, autoclaving or the like.

The backing material 2 is a sheet (a mat in the case of a thick material) made of a fiber material 2a which is generally called a sound absorbing and heat insulating material. As the name implies, the backing material 2 has excellent sound absorbing properties, heat insulating properties, flame retardancy,
It is a hydrophobic sheet. The material is microfibers with an average fiber diameter of 2 microns and short fibers with a fiber diameter of 25 microns unified into a sheet (mat-like in the case of thick) to form a sheet. It is a low-density nonwoven fabric that has the same bulkiness.

[0009] The vibration energy due to the sound transmitted to the air layer formed by the short fibers is effectively transmitted to the microfibers in the pores separated by the microfibers, and is converted into heat. For example, compared to urethane and felt, they exhibit the same level of sound absorption at a weight of about 1/2 to 1/6. Furthermore, unlike glass wool, it has no irritation to the skin (no flickering), improves workability and safety, and generates no dust even in processing such as cutting and punching.

Of course, since the back material 2 is formed of short fibers, the back material 2 has good adhesion to the core material 3 due to the anchor effect.

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 and the like. And a curing agent and a foaming agent are mixed, and the mixture is discharged to the back side of the front surface material 1 or the back surface material 2 and heated to react, foam, and cure. In the core material 3, light-weight aggregates (pearlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, Graphite, etc.) can be mixed to improve fire resistance.

The core material 3 may be a cement plate, a calcium carbonate plate, a calcium silicate plate, a ceramic plate, a wood chip cement plate, a magnesium carbonate plate, a sheathing board, a sheathing insulation board, or the like, or glass fiber, whisker, aramid or the like. Fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, etc., mixed and formed by extrusion molding, press molding, injection molding, papermaking, etc., or various fibers are woven into a cloth or three-dimensional shape Alternatively, a material obtained by impregnating the material with cement, clay, or the like and forming it into a panel shape may be subjected to steam curing or firing.

More specifically, the core material 3 is mainly made of a heat insulating material,
It functions as a fireproof material, an adhesive, a reinforcing material, a cushioning material, a sound absorbing material, a bulking material, a lightening material, and the like. Of course, an inorganic material such as rock wool, glass wool, or ceramic wool may be used as the core material 3.

At the time of construction, as shown in FIG. 2 (a), since the backing material 2 itself is crushed by the driving force of the fixing tool β,
2B is transformed into a shape as shown in FIG. 2C by itself.

The above is only one embodiment of the building panel according to the present invention, and it can be formed as shown in FIGS. 3 (a) to 3 (c) to FIG.

Particularly, FIGS. 10 (a) to 10 (e) and FIG. 11 (a)
(C) shows a building panel A on which a non-combustible board 6, a non-combustible packing material 7, and a waterproof packing material 8 are formed, which has improved fire resistance.

The non-combustible board 6 is used to reinforce the fire resistance of the connecting portion, and is a fireproof structure 1 hour test (30 minutes, 1 hour, 2 hours test) of the fireproof structure test of JIS-A-1304. For example, calcium silicate board, calcium carbonate board, gypsum board, perlite cement board, rock wool board, slate board, ALC
Board, PC board, other inorganic light-weight body, inorganic light-weight foam, or one or more of these composite boards, or ultra-high-density resin (high-density phenol foam or the like) is used as the male connecting portion 4 of the building panel A. , And are integrally interposed in the female connecting portion 5. Of course, as shown in the figure, it can be formed on both the male connecting portion 4 and the female connecting portion 5, or can be formed on one of them.

As shown in the figure, the non-combustible board 6 is formed at the ends of the male connecting portion 4 and the female connecting portion 5 without any gap, and strengthens joints which are particularly weak points of fire protection. .

The non-combustible packing material 7 is made of, for example, rock wool felt, ceramic wool, or the like, and is JIS-A
It is useful as a function mainly as a fire-resistant material, an air-tight material, etc., by preventing a gap from being formed between the connecting portions during a one-hour test of the fire-resistant structure test of -1304 to prevent the penetration of flame. .

The waterproof packing material 8 is, for example, a regular and elastic packing material such as polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt-impregnated polyurethane, EPM, EPDM and the like. It is commercially available. In addition, as a curing type packing material (sealing material), silicone type (reaction curing type, moisture curing type), modified silicone type (reaction curing type), polysulfide type (reaction curing type), polyurethane type (reaction curing type,
It is made of, for example, a moisture-curable type, an SBR type (dry-curable type), or an acrylic type (dry-curable type), and is useful mainly as a function of a waterproof material, an airtight material, and the like. Of course, a flame retardant such as an inorganic material or a fire retardant such as ammonium polyphosphate, aluminum hydroxide, phenol resin particles, carbon black, graphite (foamed or non-foamed) is mixed into these components. A refractory packing material may be used.

FIGS. 12 (a) to 12 (e) show another embodiment of the building panel A used particularly for roofing materials.

FIG. 13A shows a packing state in the case where a building panel A in which the back material 2 swells to the back side more than the front material 1 is used, and the building panel A according to the present invention is shown.
Are packed, and the total thickness is T. Also,
(B) shows a case in which eight panels each having a core material 3 made of a synthetic resin foam formed between a front surface material 1 and a back surface material 2 are packaged, and the total thickness is t. As is clear from the figure, t
−T = ΔT, and the architectural panel A according to the present invention has a smaller packing shape and requires less transportation cost by Δt.

FIGS. 14A and 14B show the backing material 2.
(A) shows a sheet-like material 2b formed on one side, and the back material 2 has weather resistance, heat resistance, and the like.
Backing material 2 with improved moisture resistance, waterproofness, shape retention, etc.,
(B) is a back material 2 in which sheet-like materials 2b are formed on both surfaces of the back material 2. Of course, as shown in FIGS. 15 (a) and 15 (b), the core member 3 is integrated with the back material 2 such that the portion exposed to the outside is on the sheet-like material 2b side.

The material of the sheet 2b may be a metal material,

Of course, when the back material 2 is formed so as not to protrude to the back side from the front material 1, the back material 2 is not compressed at the time of construction or the like, and the initial performance of the back material 2 can be improved for a long time. Can be maintained over a period of time.

FIGS. 12 (e) and 15 (c) show a building panel A in which the back surface member 2 is formed directly on the back surface of the front surface member 1. FIG.

[0027]

As described above, according to the building panel of the present invention, the sound absorbing property is improved. Flame retardancy is improved. Since the back material is hydrophobic, it does not absorb moisture and exhibits stable sound absorption and heat insulation over a long period of time. Since the bonding strength between the core material and the back material is improved, there is no peeling. Since the back material is formed of short fibers, the adhesiveness between the core material and the back material is good due to the anchor effect. When the back material is formed so as not to protrude more toward the back surface than the front material, the back material is not compressed during construction or the like, and the performance of the back material can be maintained for a long period of time. If the front material is formed so as not to protrude from the back surface of the back material, the back material can be compressed at the time of packing by the size that the back material protrudes from the front material, so the packing shape can be reduced and the transportation cost can be reduced. I can do it. There are features and effects such as.
