There is Jikko No. 54-26649. however,
There were various problems with the above board. In other words, when rainwater is blown by the wind on the board (closing board), the rainwater leaks to the back side because it is simply a connecting structure between flat plates, corroding the edges and pillars, and adding moisture to the room and closet. There was a drawback. In addition, because the length of the sloped part of the lower edge to the rising part of the board is long, it is weak in tensile force and has the disadvantage that only an exterior without joints can be formed. Furthermore, although the exterior was originally without joints, due to the skill of the builder, the exterior was made up of joints of varying widths, some without joints, some with joints, and there was a risk of injury at the rising parts during construction. In addition, the board has a complicated side shape, making it difficult and expensive to mold.Furthermore, there are no reinforcing ribs on the flat part, so warping, twisting, etc. appear on the decorative surface, which spoils the aesthetic appearance. It was hot. In addition, since all boards have no backing material and the wall base and surface material are in direct contact, condensation forms on the back of the decorative surface, leading to rust and corrosion of the wall base, and the insulation of the wall itself. Fireproof,
It lacks soundproofing properties, fails to prevent deformation of the decorative surface, and has the disadvantages that the board itself is easily deformed and lacks connection strength. Furthermore, these boards had the drawback of lacking a three-dimensional effect.

FIG. 1 is a perspective view showing the board A, which includes surface-treated steel sheets, zinc-nickel alloy plated steel plates, aluminum-zinc alloy plated steel plates (product names: GULF-AN, GALVALUM steel plate, SUPER ZINK), aluminum plates, and aluminum alloy plates. , a surface material 1 made of a metal plate (including flat plate and embossed plate) made of one type of copper plate, clad steel plate, vibration damping steel plate, etc., or a synthetic resin plate formed by one type of roll, press, or extrusion molding. , a core material 24 filled in the back surface of the surface material 1, and a sheet-like back material 25 covering the back surface of the core material 24.
To explain further, the surface material 1 includes a decorative surface part 2, a male type connecting part 9, a female type connecting part 18, as shown in FIG. 2a.
It is composed of. To explain further,
The decorative surface section 2 has a substantially gutter-like cross section, with an inclined side wall 3 bent at one end at θ ₁ (θ ₁ <90°) and a side wall 4 bent at θ ₂ at the other end. This inclined side wall 3 has θ ₁ <90°, so it improves the flow of rainwater.
Decorative pieces 2a that prevent rainwater from accumulating in the joints and are divided by decorative grooves 5, which will be described later.
It is formed at a ratio of 1:5 to 0.2, and is useful for strengthening the three-dimensional appearance of the joint area and increasing the working width through specular reflection and diffused reflection. The side walls 4 cast shadows on the joints and enhance the three-dimensional appearance of the wall. Note that θ ₂ may be an acute angle, a right angle, or an obtuse angle, but an acute angle is preferable because the shadows cast on the joints become clearer and the rainwater flowing down the surface of the decorative piece 2b is better drained. Further, at least one cosmetic groove 5 is formed in the decorative surface portion 2 along the longitudinal direction, and a plurality of horizontal decorative pieces 2a, 2b are formed by the decorative groove 5. This decorative groove 5 has a side surface 6 that intersects with the decorative piece _2a at least at an angle θ ₃ corresponding to the angle θ 2 described above.
, an inclined surface 7 that intersects with the decorative piece 2b at an angle θ ₄ corresponding to the angle θ ₁ , and a recess 8 formed between the side surface 6 and the inclined surface 7 . Furthermore, the decorative groove 5 is one in the center of the decorative surface part 2, or three to three decorative grooves 5 are provided in the center of the decorative surface part 2.
A plurality of pieces (same shape, irregular shape) are provided so as to be divided into 5 parts, mainly to prevent the decorative surface part 2 from warping, twisting, and flattening. The ratio is about 1:5 to 0.2, and the so-called mirror reflection and diffuse reflection between the decorative pieces 2a and 2b, the inclined side wall 3, and the decorative groove 5 create a different shade from the conventional decorative groove and strengthen the three-dimensional effect of the decorative surface part 2. The contrast creates a sense of unevenness, and the cross section of the joint shown in Fig. 3 and the cross section of the decorative groove 5 are almost the same or close to it, and the joint between the boards A is made into a decorative groove to create a wall design. It is something that improves one's sexuality. Note that, like θ ₂ , the size of θ ₃ may be an acute angle, a right angle, or an obtuse angle; however, in the case of an acute angle, the step becomes more obvious and the slope
It is effective for emphasizing more. In addition, the recessed portion 8 makes the division between the side surface 6 and the sloped surface 7 clear, and at the joint shown in FIG.
The appearance is made to closely resemble the part in contact with the wall, creating horizontal lines on the wall that are made up of only repeating decorative grooves 5, thereby improving the design. As shown in an enlarged view in FIG. 2b, the male connecting portion 9 includes an insertion edge 10 that projects the tip of the inclined side wall 3 outward in a manner substantially parallel to the decorative pieces 2a and 2b, and a tip of the insertion edge 10. an engagement groove 14 formed by bending inward and then outward to form a substantially U-shaped cross section; an extension portion 16 extending the lower edge 15 of the engagement groove 14 outward; Part 1
Tongue piece 1 with the tip of 6 bent into a seam shape as necessary
7, two waterproof protrusions 11 and 12 provided on the upper side of the insertion edge 10, and a groove 1 provided next to the waterproof protrusion 12.
It was formed from 3. To explain further, the insertion edge 10 is inserted into a fitting groove 19 of a female connecting part 18, which will be described later, and the engaging groove 14 engages the lower edge 22 of the fitting groove 19 to form the connecting structure of the board A. Double layered to strengthen waterproofness, engagement force, and packability,
The board A can be used both horizontally and vertically. Further, the waterproof protrusions 11 and 12 contact the upper edge 20 of the fitting groove 19 to prevent rainwater from entering from the connecting portion of the board A and to strengthen the engagement force of the board A. Furthermore, by forming two waterproof protrusions 11 and 12, a gap is formed between each waterproof protrusion 11 and 12 in the connecting structure of the board A, and this also serves to prevent capillary phenomenon together with the gap created by the groove 13. It is something. Although not shown, the waterproof protrusion 1
Caulking material between 1 and 12 or groove 13,
It is also possible to strengthen waterproofness by planting packing material. Further, the extension portion 16 is a portion where the board A is fixed to the wall base using a fixing device such as a nail at a position where rainwater does not directly infiltrate. Furthermore, the tongue piece 17 prevents the tip of the extension part 16 from waving, and also prevents injuries caused by the edge of the extension part 16 during work. Although not shown, the tongue piece 1
It is also possible to form 7 in the shape of an upper seam and to sandwich the edge of the back material 25. As shown in an enlarged view in FIG. 2c, the female connecting portion 18 has a fitting groove 19 formed by bending the edge of the side wall 4 inward to have a substantially U-shaped cross section, and a fitting groove. 19, and a tongue piece 23 provided by bending the tip of the lower edge 22 of the fitting groove 19 into a seam shape. This fitting groove 19 fits the insertion edge 10, and the lower edge 22 engages with the engagement groove 14. In addition, the stepped piece 21 of the upper edge 20 prevents the connection part from rattling due to the height of the waterproof protrusions 11 and 12 formed on the upper surface of the insertion edge 10, as shown in FIG.
This was provided to maintain the flatness of the wall. Further, the tongue piece 23 prevents the edge of the lower edge 22 from waving, makes it easier to insert the lower edge 22 into the engagement groove 14, and prevents injury caused by the edge of the lower edge 22. Note that the tongue piece 23 is formed into an upper flap shape as shown in the figure to sandwich the edge of the back material 25 to strengthen the integration of the surface material 1, the core material 24, and the back material 25, and also to It is also possible to prevent leakage from around the female connecting portion 18, or to form it in the shape of a bottom seam (not shown). Core material 2
4 fills at least a gutter-shaped portion surrounded by the decorative surface portion 2, the male connecting portion 9, and the female connecting portion 18 on the back side of the surface material 1, and mainly provides insulation to the board A. A material that has secondary functions such as adhesives, noncombustible materials, cushioning materials, and soundproofing materials.
It consists of more than one species. Specifically, it is made of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., and it is made of raw materials that are discharged, molded, hardened, and self-adhesive, or it is made of a molded body. In addition, when using a molded body as the core material 24, an adhesive (not shown) is required between the core material 24, the surface material 1, and the back material 25. To explain further, the core material 24
Generally, synthetic resin foams are used, such as resins for polyurethane foam, resins for phenol foam, resins for polyisocyanurate foam, polystyrene foam, and perlite, which are coated with phenol foam resin, and then heated.
Foam that is foamed under pressure, and flame retardants and flame retardant aids (borax, sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide, bentonite, perlite grains, shirasu balloons, asbestos, rock wool, various fibers). 1
It consists of things with added seeds or more. A recessed portion 24a is formed in the vicinity of the female connecting portion 18 of the core material 24, and in combination with the extension portion 16 at the connecting portion of the board A, looseness is removed and the fit of the board A is improved. Further, although not shown, the core material 24 may be provided to bulge downward from the back surface of the extension portion 16 to further improve heat insulation and fire protection. In addition, when using a phenol foam-based synthetic resin for the core material 24, it is also possible to apply an anti-rust paint to the back surface of the surface material 1 so that the acidic component of the core material 24 does not come into direct contact with the surface material 1. be. 2
5 is a backing material that covers at least the backside of the core material 24 to give the board A a sandwich structure, which improves the mechanical strength of the board A itself, and also includes a noncombustible sheet, a waterproof membrane, a heat shielding sheet, a water absorption sheet, a soundproof sheet, and a packing material. For example, asbestos paper, kraft paper, asphalt felt, metal foil (A, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass. It is made of a laminate of one or more types of fibrous nonwoven fabrics, etc., or a sheet that has been treated with waterproofing or flame retardant treatment. Note that both ends of the backing material 25 may be held between the tongue pieces 17 and 23, or placed between the surface material 1 and the core material 24, or placed outward from the edge of the male connecting portion 9. It is also possible to stand out.

る。 As mentioned above, according to the board according to the present invention,
Since the male and female joints have the above-mentioned drop-in structure, even one person can perform the work, and the joint width can be kept constant. Since at least one decorative groove is formed in the decorative surface part, the strength is sufficiently reinforced, the decorative surface part can be prevented from warping, twisting, and flattening, and the decorative surface part does not become mountain-like. Since the decorative grooves and the joints have almost the same cross-sectional shape, the entire wall has no joints and is made up of only the so-called decorative grooves, making it possible to form a wall that is both beautiful and rich in design. The decorative surface portion is formed as follows: inclined side wall - decorative piece - side surface of the decorative groove - inclined surface of the decorative groove - decorative piece - side wall, and the ratio of decorative piece: inclined side wall, decorative piece: inclined surface is 1:5.
By increasing the width of the sloped side walls and slopes as shown in ~0.2, we effectively utilized diffused reflection and specular reflection to create a bulge in the decorative piece, and on top of that, we created a decorative groove similar to the joint area to reduce the level difference. It is possible to make the wall clearer and make the decorative pieces stand out to create a wall with a three-dimensional effect. Since the board connection structure is double, engagement force and packing performance are improved. A waterproof protrusion is formed on the upper side of the insertion rim, increasing waterproofness and engagement force.
In the connection structure of the board, there is no capillary phenomenon due to the gap between the two waterproof protrusions and the gap formed by the groove, and the waterproof property is improved. The board has a sandwich structure, which greatly improves its mechanical strength.
Since the board can be made wide, it is easy to construct, and the width of the material can be used effectively, making it highly economical. The board can be stretched vertically or horizontally. Flatness of the entire wall can be easily obtained. It has the following characteristics.
