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. fire retardant,
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.

A plurality of horizontal decorative pieces are formed by providing at least one decorative groove formed from the side surface and the inclined surface in the decorative surface portion having the side wall and the inclined side wall formed at both ends, and the ratio of the inclined surface and the inclined side wall to the decorative piece is increased. By doing so, the cosmetic piece appears to stand out due to specular reflection and diffused reflection, thereby enhancing the three-dimensional effect, and is bent from the middle of the inclined side wall to form a primary inclined side wall and a secondary inclined side wall, The sloped surface of the decorative groove also forms a primary sloped surface and a secondary sloped surface in the same way as the sloped side wall to promote diffused reflection and improve the three-dimensional effect and design. It prevents twisting, twisting, and warping, and improves economic efficiency and workability by forming the board wide. Also, the edge of the inclined side wall of the decorative surface section is equipped with a male connecting part with an insertion edge and an engaging groove. A female connecting part with a fitting groove is formed on the edge of the side wall, and the connecting structure of the board is made double by the insertion edge and the fitting groove, and the engaging groove and the lower edge of the fitting groove. To propose a board that has improved engagement force and waterproofness, is a drop-in type that can be easily installed by one person when horizontally installed, and can also be used vertically.

る。 Hereinafter, typical embodiments of the board according to the present invention will be described in detail with reference to the drawings. That is,
FIG. 1 is a perspective view showing the board A, which includes, for example, surface-treated steel sheets, zinc/nickel alloy plated steel sheets, aluminum/zinc alloy plated steel sheets (product names: Gulfuan, Galvalume steel sheet, Super Zinc), 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 by one type of roll, press, or extrusion molding. , a core material 22 filled in the back surface of the surface material 1, and a sheet-like back material 23 covering the back surface of the core material 22.
To explain further, the surface material 1 is formed from a decorative surface part 2, a male type connecting part 9, and a female type connecting part 17, as shown in FIG. That is, the decorative surface section 2 has an inclined side wall 3 at one end, a side wall 4 at the other end, and has a substantially gutter-like cross section. This inclined side wall 3 is bent in the middle and formed from a plurality of surfaces. That is, in the figure, a primary inclined side wall 3a intersects with the decorative piece 2a at θ ₁ ,
Secondary inclined side wall 3b intersects with primary inclined side wall 3a at θ ₂
Since it consists of a plurality of inclined surfaces, it is possible to effectively utilize diffused reflection, and the makeup piece 2a
can be made to stand out more and enhance the three-dimensional effect. Furthermore, since the sloped side wall 3 is sloped, it improves the flow of rainwater and prevents rainwater from accumulating in the joints. It is formed to have a ratio of 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. Furthermore, since the inclined side wall 3 is bent in the middle, the inclined side wall 3 can be made up of a plurality of flat surfaces without twisting or wobbling. Further, the side wall 4 is formed by bending the other end of the decorative surface portion 2 at an angle of θ ₃ , and casts a shadow on the joint portion to enhance the three-dimensional appearance of the wall body. Reference numeral 5 denotes a decorative groove formed from a side surface 6, an inclined surface 7, and a recessed portion 8 provided between the side surface 6 and the inclined surface 7. In particular, the inclined surface 7 is formed from a plurality of surfaces by being bent in the middle, similar to the above-mentioned inclined side wall 3. That is, as shown in the figure, the inclined surface 7 has a plurality of inclined surfaces, such as a primary inclined surface 7a that intersects with the decorative piece 2b at θ ₅ , and a secondary inclined surface 7b that is formed by bending the tip of the primary inclined surface 7a at θ ₆ . The decorative groove 5 produces the same action and effect as the inclined side wall 3. Further, the side surface 6 intersects with the decorative piece 2a at θ ₄ and produces the same action and effect as the side wall 4. Furthermore, the cosmetic groove 5 is one in the center of the decorative surface part 2, or a plurality of grooves (same shape, irregular shape) are provided so as to divide the decorative surface part 2 into 3 to 5 parts, to prevent warping, twisting, and unevenness of the decorative surface part 2. It is also useful for prevention. Note that θ ₄ may be an acute angle, a right angle, or an obtuse angle, but an acute angle makes the step more clear and is effective in emphasizing the slope 7, especially the secondary slope 7b. Also, the depression 8
is formed into a shape produced by bending the surface material 1 or into an arbitrary shape, and it clarifies the division between the side surface 6 and the inclined surface 7, and also forms the side wall 4 at the joint shown in FIG. The external appearance is made to closely resemble the contact portion of the wall and the inclined side wall 3, and a line is created on the wall body as if it were made up of repeated decorative grooves 5, thereby improving the design. Reference numeral 9 denotes a male connecting portion, which includes an insertion edge 10 with the tip of the inclined side wall 3 projecting outward, an engagement groove 13 having a U-shaped cross section with the insertion edge 10 as the upper edge, and a lower part of the engagement groove 13. An extension part 15 that extends the edge 14 outward, a tongue piece 16 that is bent into a flap shape at the tip of the extension part 15 as necessary, a groove part 11 provided on the upper side of the insertion edge 10, and a reinforcing rib (see FIG. In this case, it is formed from pipe-shaped) 12. To explain further, the insertion edge 10 is inserted into a fitting groove 20 of a female connecting part 17, which will be described later, and the engaging groove 13 is inserted into a fitting groove 20 of a female connecting part 17, which will be described later.
0 to connect the connecting structure of board A by engaging the lower edge 19 of board A.
By increasing the weight, the waterproofness, engagement force, and packability are strengthened, and the board A can be used both horizontally and vertically. Further, the groove portion 11 forms a void in the connecting structure of the board A to prevent capillary phenomenon, and the reinforcing rib 12 functions as a rain cover. In addition,
It is also possible to interpose a core material 22 between the upper side and the lower side of the insertion edge 10. In addition, the extension part 15
is the part where board A is fixed to the wall base using fixing tools such as nails at a location where rainwater will not directly infiltrate. Further, the tongue piece 16 prevents the tip of the extension part 15 from waving, and also prevents injuries caused by the edge of the extension part 15 during work. Although not shown, caulking material is applied to a portion of the groove 11.
It is also possible to install packing material to further strengthen waterproofness. Further, the tongue piece 16 can be formed in the shape of an upper seam and can hold the edge of the back material 23. The female connecting portion 17 bends the edge of the side wall 4 inward to form an upper edge 18 and then outwards to form a lower edge 1.
9, and the cross section from the upper edge 18 and the lower edge 19 is approximately U.
It is composed of a fitting groove 20 formed in a letter shape and a tongue piece 21 whose tip of the lower edge 19 is bent into a seam shape. This fitting groove 20 fits the insertion edge 10, and the lower edge 19 engages with the engagement groove 13.
Further, the tongue piece 21 prevents the edge of the lower edge 19 from waving, makes it easier to insert the lower edge 19 into the engagement groove 13, and prevents injury caused by the edge of the lower edge 19. Note that the tongue piece 21 is formed into an upper flap shape as shown in the figure to sandwich the edge of the back material 23 to strengthen the integration of the surface material 1, the core material 22, and the back material 23, and to strengthen the integration of the core material 22. It is also possible to prevent leakage from around the female connecting portion 17, or to form a bottom groove (not shown). The core material 22 is the surface material 1
It fills at least the gutter-shaped part surrounded by the decorative surface part 2, the male connecting part 9, and the female connecting part 17 on the back side of the board A, and mainly gives insulation to the board A. It is made of one or more materials that have functions such as adhesives, noncombustible materials, cushioning materials, and soundproofing materials. 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 22, the core material 22 and the surface material 1,
An adhesive (not shown) is required between the backing materials 23. To explain further, a synthetic resin foam is mainly used as the core material 22, for example, a resin for polyurethane foam, a resin for phenol foam, a resin for polyisocyanurate foam, a polystyrene foam, a phenol foam resin is coated around the perlite, Foam is foamed by heating and pressurizing this, and flame retardants and flame retardant aids (borax, sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide, bentonite, pearlite grains, shirasu balloons) are added to these foams. It consists of things with added seeds or more. A recessed portion 22a is formed in the vicinity of the female connecting portion 17 of the core material 22, and in combination with the extension portion 15 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 22 may be provided to bulge downward from the back surface of the extension portion 15 to improve heat insulation and fire protection. Reference numeral 23 is a backing material that covers at least the backside of the core material 22 to give the board A a sandwich structure, which improves the mechanical strength of the board A itself, as well as a noncombustible sheet, a waterproof membrane, a heat shielding sheet, a water absorbing sheet, a soundproofing sheet, and a packing material. For example, asbestos paper, kraft paper, asphalt felt, metal foil (A, Fe, Pb, Cu), etc.
1. Synthetic resin sheets, rubber sheets, cloth sheets, gypsum paper, aluminum hydroxide paper, glass fiber non-woven fabrics, etc.
It is made of seeds, a laminate of two or more kinds, or a sheet that has been treated with waterproofing or flame retardant treatment. Note that both ends of the back material 23 are attached to the tongue piece 1.
6 and 21, disposed between the surface material 1 and the core material 22, or protruded outward from the edge of the male connector 9.

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. Bend the inclined side wall and the inclined surface of the decorative groove from the middle,
Because it is formed from multiple flat slanted surfaces,
It can fully exhibit diffused reflection, enhancing the design and three-dimensional effect. Since the inclined sidewalls and the inclined surfaces of the decorative grooves are bent in the middle, there is no twisting or twisting even if the range of the inclined sidewalls and inclined surfaces is increased. Because the board has a sanderch structure,
Mechanical strength is greatly improved. 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. Since the board connection structure is double, engagement force and packing performance are improved. In order to form a gap formed by the groove of the insertion edge of the male type connection part in the connection structure of the board, capillary phenomenon is prevented,
Excellent waterproofness. It has the following characteristics.
