2. Description of the Related Art Generally, a dry method using a ceramic siding material or a metal siding material as an interior material or an exterior material has become mainstream. In particular, expensive aluminum, stainless steel, titanium, etc. are used for remodeling (renovation) and special environments such as near the coast. Resin panels are also used depending on the construction site.

[0003]

However, the ceramic siding material is heavy and poor in workability, and waterproof,
There was a disadvantage in that the coating film lacked in durability. Furthermore, when a surface-treated steel sheet is used as a metal-based siding material, especially as a surface material, there is a problem in corrosion resistance or chemical resistance against rust, etc. Therefore, it is necessary to coat with a special coating film with good corrosion resistance. There was a weakness that increased costs. Further, the resin panel had no fireproof property and the usable range was very narrow. Further, the resin panel is weak in strength, and there is a risk that the connecting portion is broken by an external force and the resin panel itself is peeled off. Further, fixing the resin panel is very difficult, and as shown in FIG. 24, a loose hole is formed on the fixing surface and a gap a (about 1 mm) is formed between the fixing surface and the head β ₁ of the fixing tool β. , The resin panel itself had to be fixed firmly. In addition, the single resin panel is greatly deformed by heat, and a space of about 7 to 10 mm is formed between the wood surface and the end member (extruded corner, entering corner, toe, joiner, etc.) during construction. It was necessary to do so, it took time for construction, and skill and precision were required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the building panel according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a cross-sectional view showing a typical example of a building panel according to the present invention, in which A is a building panel in which a core material 3 is formed between a resin surface material 1 and a back surface material 2, and male and female members are formed at upper and lower ends. Mold connection part 4, female connection part 5
Is formed. Further, FIG. 2 is a cross-sectional view showing a construction state.

As shown in FIG. 3, the male connecting portion 4 has a side surface 7 in which the lower end of the decorative surface 6 is bent inward, an upper surface 8 in which the tip of the side surface 7 projects upward, and a tip of the upper surface 8 in the downward direction. It is formed by a fitting surface 9 that is bent and hangs down, and a fitting groove 10 that is formed from the fitting surface 9 and the upper surface 8 in a substantially inverted U-shaped cross section.

As shown in FIG. 4 and FIG. 5 (enlarged cross-sectional view), the female connecting portion 5 has a side surface 11 which is bent inwardly at the upper end of the decorative surface 6 and a tip of the side surface 11. 2 above
Engaging surface 13, engaging surface 14 protruding in parallel, and engaging surface 1
3 and the engaging surface 14, and an engaging portion 12 formed by a gap 15 formed by the engaging surface 14 and a packing piece 16 made of two soft synthetic resins in the figure formed continuously on the outer engaging surface 13.
A lower surface 17 protruding upward from the base of the engaging portion 12, an engaging groove 18 formed in a U-shaped cross section from the lower surface 17 and the engaging portion 12, and a fixing surface 19 further protruding the lower surface 17. The two projections 20 are formed on the fixed surface 19, and the fixing portion 22 is formed on the fixed surface 19 and is formed of a plurality of elongated fixing holes 21 as shown in FIG.

Reference numeral 6a is an unevenness, which improves the design of the decorative surface 6. Further, the decorative groove 6b divides the decorative surface 6 into a plurality of decorative surfaces 6, and the building panel A has a narrow width.
The workability is improved by forming it as a plurality of sheets.

The fitting groove 10 is the engaging portion 12 of the female connecting portion 5.
2, and the fixing surface 19 is fixed to the frame α via the fixing tool β to form a wall surface as shown in FIG.

Further, by forming the engaging portion 12 with the engaging surface 13 and the engaging surface 14, the connecting strength is improved. Further, the gap 15 of the engaging portion 12 exerts a springback function, which is effective for further improving the connection strength, waterproofness, airtightness, and the like.

The packing piece 16 is made of a soft synthetic resin and has a waterproof property of the connecting portion such as the engaging surface 13, the engaging surface 14 and the gap 1.
It is intended to be improved by the synergistic effect with 5. The packing piece 16 is integrally extruded together with the main body of the resinous surface material 1.

As shown in FIG. 2, the fixing surface 19 is a portion for fixing the building panel A to the frame α by the fixing tool β.

As shown in FIG. 6, the fixing hole 21 is formed in a horizontally long shape (loose hole), and the deformation of the resin surface material 1 due to thermal expansion and contraction in the longitudinal direction is not hindered by the mounting of the fixing tool β. It is absorbed by the fixing hole 21. Therefore, due to the deformation of the resin surface material 1 that occurs when the fixing surface 19 is firmly fixed by the fixing tool β, the fixing surface 19 does not fall off from the fixing tool β, and the building panel A is constructed with the frame α ( It prevents peeling from the wooden base, steel frame base, asphalt felt, etc.). Of course,
The fixture β is fixed to the center of the fixing hole 21.

As shown in the enlarged view of FIGS. 2 and 5, the fixing portion 22 can be formed by forming two protrusions 20 without fixing the head portion β ₁ of the fixing member β to the fixing surface 19. It was done like this. Of course, the diameter of the head β ₁ is equal to that of the fixed portion 2.
It is larger than the width of 2.

For this reason, the constructed building panel A can absorb the expansion and contraction due to heat, the building panel A itself is not deformed by expansion and contraction, and the decorative surface 6 is not distorted, and is also deformed by heat contraction. As a result, the building panel A will not be peeled off from the frame α. Further, the fixing portion 22 is intended to improve the fixing efficiency of the difficult resin panel, simplify the fixing, and ensure the fixing.

The backing material 2 serves to improve the strength of the building panel A as a sandwich structure. Examples of the material include kraft paper, aluminum foil,
Roll-molding aluminum kraft paper, non-woven fabric (carbon, alumina, rock wool, graphite, inorganic fibers such as glass, polyester, nylon, aramid resin), asphalt felt, metal foil, or metal sheet It is formed into various shapes by press molding, extrusion molding or the like.

The core material 3 is a trough-shaped portion 2 on the back surface of the resin surface material 1.
3 backing material of synthetic resin foam 24 (having functions such as backup material, heat insulating material, fireproof material, reinforcing material, deformation preventing material, etc.)
As the synthetic resin foam 24, polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., or inorganic lightweight aggregate, inorganic It is made of a material mixed with an inorganic material such as fiber.

According to the building panel A formed as described above, the linear expansion coefficient of the building panel A formed of the single resin surface material 1 made of PVC is 9 when measured at room temperature (20 ° C. or higher). In contrast to 0.5 × 10 ⁻⁵ , the linear expansion coefficient of the building panel A in which the synthetic resin foam 24 made of polyisocyanurate foam is formed as the core material 3 on the resin surface material 1 made of PVC is 6. It was 7 × 10 ⁻⁵ .
It is considered that this is because even if the surface temperature during PVC heating rises, the temperature of the foam does not rise due to the heat insulating effect of the foam, the expansion of the foam is small, and the elongation of the PVC is suppressed. In particular, it is effective in preventing elongation of the resin surface material 1 in the summer (every summer).

If this is converted to a length of 1 m, the construction panel A formed of a single resin surface material 1 made of PVC has a surface area of 0.095 mm / ° C., whereas the resin surface material 1 made of PVC has Building panel A in which a synthetic resin foam made of polyisocyanurate foam is formed as the core material 3.
Is 0.067 mm / ° C., which is a decrease of about 30%. Of course, in the case of the building panel A in which the backing material 2 is further formed, the expansion / contraction rate is further reduced significantly.

What has been described above is only one embodiment of the building panel according to the present invention, and FIGS. 7 (a) to (h) to FIG.
The building panel A can be formed as shown in (a) to (h).

That is, FIGS. 7A to 7H and FIG.
(A)-(e) shows other examples of the fixed part 22.

Further, FIGS. 9 (a) and 9 (b) to FIG. 22 (a)
(H) shows other examples of the building panel A, and the male type | mold connection part 4, the female type | mold connection part 5, the decorative surface 6, the back surface material 2, the core material 3, etc. of the resin-made surface material 1 are shown. Is a building panel A in which each of the above is modified.

FIG. 23 is an enlarged cross-sectional view showing a portion of the resin surface material 1, which is a mixture of synthetic resin 25 (plastic) with resol-type phenol resin powder 26 added thereto.

The resol type phenol resin powder 26 is, for example, spherical and has a size of about 0.02 to 10 mm and a bulk density of about 0.065 to 0.8 g / cm ³ , and (a) is a heat melting type, ( There are four types such as b) partial heat melting type, (c) heat non-melting type, and (d) firing type. The purpose of the resol type phenolic resin powder 26 is to improve the heat resistance of the synthetic resin 25 lacking heat resistance, improve the mechanical strength of the synthetic resin 25 lacking compressive strength, improve weather resistance, and maintain the flatness of the appearance of the decorative surface. This is for strengthening, improving the fluidity when molding the synthetic resin 25, and the like. The addition amount varies depending on the purpose, but is, for example, 10 to 200 parts by weight relative to 100 parts by weight of the synthetic resin 25 raw material.

Therefore, for the building panel A in which the resol type phenol resin powder 26 is mixed, JIS-A-1 is used.
When the quasi-nonflammability test according to 321 was conducted, it passed.

[0027]

As described above, according to the building panel of the present invention, the weather resistance can be improved. Because the resin surface material is a synthetic resin, it does not rust or rot. Since the resin surface material is a synthetic resin, the weight can be reduced and the workability is good. Good workability such as cutting. Expansion and contraction of the building panel due to heat after construction can be absorbed by the fixing portion, and even if the building panel A itself expands and contracts, the decorative surface is not deformed and distorted. The building panel will not be separated from the body due to the deformation of the building panel itself due to heat shrinkage. Since two engaging surfaces are formed, a springback effect is exerted at the connecting portion, and it is possible to improve the fixing efficiency of a difficult resin panel, simplify the fixing, and ensure the fixing. Since the soft packing pieces are formed, the waterproof property is improved.
Since the synthetic resin foam is formed on the back surface of the resin surface material, the expansion of the resin surface material is particularly reduced, and the workability, heat insulation (reduction of gaps), prevention of peeling, and maintenance of aesthetics for a long time are achieved. To be There are features and effects such as.
