易に得られる。等の特徴がある。 [Detailed description of the invention] [Industrial application field] The present invention is a siding board (hereinafter simply referred to as a board) that is useful for forming horizontal and vertical walls inside and outside buildings and structures. ) regarding. [Prior art] This type of board that has been used in the past includes Tokoku No. 51-29339, Utility Model No. 51-11882,
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. Moreover, 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.
It had the disadvantage that warping, twisting, etc. appeared significantly on the cosmetic surface, impairing its aesthetic appearance. 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. In addition to lacking fireproofing and soundproofing properties, the board itself could not be deformed easily, and the board itself was easily deformed, and it lacked connection strength. Furthermore, these boards had the drawback of lacking a three-dimensional effect. [Purpose of the invention] In order to eliminate the above-mentioned drawbacks, the present invention provides a range of sloped side walls of a decorative surface section in which side walls and sloped side walls are formed on both ends of a horizontal decorative piece, and the cross section is approximately gutter-shaped. The width ratio of the decorative piece is set to 1:5 to 0.2, which is larger than before, and when the board is installed, the decorative piece stands out and enhances the three-dimensional effect.
Moreover, a male type connecting part consisting of an insertion edge and an engaging groove is provided at the edge of the inclined side wall, and a female type connecting part consisting of a fitting groove is provided at the end edge of the side wall, and the connecting structure of the board is inserted. The edges and the fitting groove, and the engagement groove and the lower edge of the fitting groove are double-layered to strengthen waterproofness, engagement force, and packing properties, and are easy to install when the board is used for horizontal mounting. , we are proposing a board that is a drop-in type that can be carried out by one person, and that can also be used as a vertical board. [Structure of the invention] Representative embodiments of the board according to the invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a perspective view showing the board A, which includes, for example, a surface-treated steel sheet, a zinc-nickel alloy plated steel sheet,
Metal plates (including flat plates and embossed plates) made of one type of aluminum/zinc alloy plated steel plate (product name: Gulfuan, Galvalume steel plate, Super Zinc), aluminum plate, aluminum alloy plate, copper plate, clad steel plate, vibration damping steel plate, etc. , a surface material 1 formed from a synthetic resin plate by one type of rolling, pressing, or extrusion molding, a core material 18 filled on the back surface of the surface material 1 , and a sheet-like back surface covering the back surface of the core material 18. It is formed from material 19.
To explain further, the surface material 1 is composed of a decorative surface part 2 , a male connecting part 5 , and a female connecting part 13 , as shown in FIG. To explain further, the decorative surface section 2 consists of a horizontal decorative piece 2a, an inclined side wall 3 bent at θ ₁ (θ ₁ <90°) at one end of the decorative piece 2a, and a side wall 4 bent at θ ₂ at the other end. The cross section is approximately gutter-shaped. Since this inclined side wall 3 has θ ₁ <90°, it improves the flow of rainwater and prevents rainwater from accumulating in the joints.
It can be set arbitrarily from 5 to 0.2, and depending on the ratio, the appearance, especially the flatness of the decorative surface part 2 itself, the reinforcement of the three-dimensional effect, and the productivity (the more the decorative pieces 2a are, the more steel belts and rollers are used to manufacture them). This has a large impact on In addition, the mirror reflection and diffused reflection between the inclined side wall 3 and the decorative piece 2a make the decorative piece 2a stand out, giving the wall a three-dimensional effect.
It is useful for enhancing the three-dimensional appearance of joints and increasing the working width. In addition, 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 effect of draining rainwater flowing down the surface of the decorative piece 2a is better. Male connection part 5
an insertion edge 6 protruding outward from the tip of the inclined side wall 3 substantially parallel to the decorative piece 2a; an engagement groove 9 having an approximately U-shaped cross section with the insertion edge 6 as the upper edge; Extension portion 11 that extends the lower edge 10 of the engagement groove 9 outward
and a tongue piece 12 which is bent into a seam shape at the tip of the extension part 11 as required. To explain further, the insertion edge 6 is a female connecting portion 1 which will be described later.
3, and the engagement groove 9 engages the lower edge 15 of the engagement groove 16 to double the connection structure of the board A, strengthening waterproofness, engagement force, and packing performance. However, the board A can be used both horizontally and vertically. Further, on the upper side of the insertion edge 6, a groove 7 recessed parallel to the longitudinal direction and a reinforcing rib (pipe-shaped in the figure) 8 are formed at the tip, if necessary. This groove 7 serves to form a void in the connecting structure of the board A, as shown in FIG. 3, and to prevent capillary action.
Further, the reinforcing ribs 8 function as rain repellents within the connecting structure of the boards A, prevent capillary action in the grooves 7, and strengthen the waterproofness of the connecting portions. Further, the extension portion 11 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. Further, the tongue piece 12 has an extension portion 11
This prevents the tip of the extension part 11 from waving and also prevents injuries caused by the edge of the extension part 11 during operation. Although not shown, the tongue piece 12 can also be formed in the shape of an upper seam so as to sandwich the edge of the back material 19. The female connecting portion 13 bends the edge of the side wall 4 inward to form an upper edge 14 .
Bend the tip outward to form the lower edge 15, and form the upper edge 1.
4 and the lower edge 15, the fitting groove 16 is formed into a substantially U-shaped cross section, and a tongue piece 17 is bent at the tip of the lower edge 15 as necessary. be. This fitting groove 16 fits the insertion edge 6,
Further, the lower edge 15 engages with the engagement groove 9 to double the connection structure of the board A. In addition, the tongue piece 17
This prevents the edge of the lower edge 15 from waving and makes it easier to insert the lower edge 15 into the engagement groove 9.
This is to prevent injury caused by the edge of the lower edge 15. Note that the tongue piece 17 is formed in the shape of an upper flap as shown in the figure to sandwich the edge of the back material 19, and the tongue piece 17
It is possible to strengthen the integration of the core material 18 and the back surface material 19, and to prevent leakage of the core material 18 from around the female connecting portion 13 , or to form a bottom seam shape (not shown). . The core material 18 includes a decorative surface portion 2 on the back side of the surface material 1, a male connecting portion 5 , and a female connecting portion 1.
3. It fills at least the gutter-shaped part surrounded by , and mainly gives insulation to board A, and also functions as an adhesive, noncombustible material, cushioning material, soundproofing material, etc. It is made of one or more of the following 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 molded bodies. In addition, when using a molded body as the core material 18, the core material 18 and the surface material 1 ,
An adhesive (not shown) is required between the backing materials 19. To explain further, a synthetic resin foam is mainly used as the core material 8, and for example, a resin for polyurethane foam, a resin for phenol foam, a resin for polyisocyanurate foam, a polystyrene foam, or a phenol foam resin is coated around the pearlite. , a foam that is heated and pressurized to cause it to explode, and flame retardants and flame retardant aids (borax, sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide, bentonite, pearlite grains, shirasu balloons, asbestos). , various fibers). In addition, a recessed part 18a is formed in the vicinity of the female connecting part 13 of the core material 18, and in combination with the extension part 11 at the connecting part of the board A, backlash is removed and the fitting property of the board A is improved. Although not shown, the core material 18 may be provided to bulge downward from the back surface of the extension part 11 to further improve heat insulation and fire protection. In addition, when using a phenol foam-based synthetic resin for the core material 18, 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 18 does not come into direct contact with the surface material 1 . be. Reference numeral 19 is a backing material that covers at least the backside of the core material 18 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 absorption sheet, a soundproofing sheet, and a packing material. For example, 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., or a laminate of one or more of them, or a sheet that has been treated with waterproofing or flame retardant treatment. It consists of etc. Note that both ends of the backing material 19 may be held between the tongue pieces 12 and 17, or placed between the surface material 1 and the core material 18, or placed outward from the edge of the male connecting portion 5 . It is also possible to stand out. Here, the sizes of each of the above parts will be explained. As shown in FIGS. 1 and 2, the length of the decorative piece 2a is L, the range of the inclined side wall 3 is W, the distance from the edge of the inclined side wall 3 to the tip of the insertion edge 6 is l ₁ , and Matching groove 9
The distance from the innermost part of the engagement groove 9 to the tip of the insertion edge 6 is l ₂ , and the distance from the innermost part of the engagement groove 9 to the end edge of the extension part 11 is l 2 .
l ₃ , the distance from the innermost part of the fitting groove 16 to the lower end of the side wall 4 is l ₄ , the distance from the innermost part of the fitting groove 16 to the tip of the lower edge 15 is l ₅ , the range of the recess 18a is l ₆ , The height from the upper surface of the insertion edge 6 to the surface of the extension part 11 is h ₁ ,
If the height from the lower edge of the side wall to the lower edge 15 is _h2 , then
The relationships are l ₁ ≒ l ₄ , l ₂ ≒ l ₅ , l ₂ ≒ l ₆ , h ₁ ≒ h ₂ , and the relationship W:L=1:5 to 0.2. That is,
The above relationship means that when the boards A are connected, there is no looseness at the connecting part, the decorative piece 2a becomes flat, and the three-dimensional effect of the wall is improved by specular reflection and diffused reflection between the inclined side wall 3 and the decorative piece 2a. It is for the purpose of Incidentally, the relationship between l ₁ and l ₂ can be any of l ₁ =l ₂ , l ₁ <l ₂ , and l ₁ >l ₂ as shown in FIGS. 4 a to c. Further, the relationship between l ₄ and l ₅ is also similar. [Construction Example] Now, assume that boards A as shown in FIG. 1 are laid horizontally as shown in FIG. 3 to form a wall. In addition, for boards A ₁ and A ₂ , a 0.27 mm thick color steel plate is used for the surface material 1 , aluminum kraft paper is used for the back material 19, and the core material 18 is made of the surface material 1 and the back material 1.
The raw material for polyisocyanurate foam was discharged during 9, reacted and foamed, and then cured and integrated. Therefore, the nth board is placed on the wall base consisting of main pillars, studs, waterproof sheets, etc. (the figure shows the wall base when no waterproof sheets are used).
The extension part 11 of _A1 is fixed via the nail β. Next, the fitting groove 16 of the female connecting portion 13 of the n+1th board A ₂ is combined with the insertion edge 6 of the board A ₁ to achieve waterproofness, engagement force, and packing as shown in FIG. 3. It forms a joint area with rich characteristics. In addition, in order to form the entire wall, the steps described above may be performed from the base to the girder. Although not shown, it is necessary to use a starter for the base, jointer and caulking for the vertical joints, and caulking and accessories for the exit and entry corners. Note that, as described above, this board A can also be used vertically. [Other Embodiments] What has been described above is only one embodiment of the board A according to the present invention, and it can also be formed as shown in FIGS. 5a-g to 15a-j.

In addition, in the figures i, o, p, and tv, the fitting groove 16 or both or either of the upper edge 14 and the lower edge 15 are formed at an arbitrary angle to further improve the engagement force, waterproofness, and heat insulation. This is a reinforced fitting groove 16. Further, FIGS. 13 a to 13 j and 14 a to d are explanatory diagrams showing how the back material 19 is attached at the ends of the male and female connecting portions 5 and 13 , and in FIG. The back material 19 is laminated on the back surface of the extension part 11, or
Adhesion, Figures b, e, g, i, and j are used to prevent liquid leakage when the core material 18 is discharged as a raw material, or as a mold release material, and Figure c is to hold it between the tongues 12 and prevent the deformation of board A. This is an installed state with improved prevention and improved mechanical strength. 14a to 14d show the state in which the back material 19 is attached to the female connecting portion 13 side, and the purpose, function, and effect are the same as in FIG. 13. Furthermore, FIGS. 15a to 15d show the deformation of the core material 18 and the decorative surface part 2 , and FIGS. 15a to 15d show the core material 18 and the extension part 11
Boards A and d, which bulge out further downward to improve heat insulation and fire protection, are boards A and e, in which the core material 18 is made of multiple materials (same and different), and the functions of each material are combined. Figures ~g show board A with a circulation groove 20 formed on the back side and an air cycle effect added to the wall, and Figure h shows caulking in at least one of the positions indicated by hatching of the male connection part 5 and the female connection part 13 . The caulking material 21 may be a hot melt adhesive, a molded packing material, or a packing material with no adhesive strength planted with a hot melt adhesive after applying the adhesive. Board A, which is designed to improve waterproofness, has an end wall 22 formed on both edges or one edge of the decorative surface section 2 in the short direction, and the boards A are aligned in the longitudinal direction. Board A, which facilitates waterproofing of vertical joints, is a board A in which one or a plurality of protruding or concave intermediate decorative ribs 2b are formed on the decorative piece 2a. Of course, Figures 4 a to c to 15
It is also possible to create a board A that is a combination of each of figures a to j. [Effects of the invention] As mentioned above, according to the board according to the 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. The decorative surface part is formed like an inclined side wall - decorative piece - side wall, and the width of the inclined side wall is increased such that the ratio of inclined side wall: decorative piece is 1:5 to 0.2, so that diffused reflection and specular reflection can be effectively utilized. By making the decorative pieces bulge and making them stand out, it is possible to form a wall with a three-dimensional effect. Since the slanted side walls also serve as decorative surfaces, the board can be made wider, improving workability and economy. Since the board connection structure is double, engagement force and packing performance are improved. Since the groove is formed on the upper surface of the insertion edge, capillarity can be prevented. A reinforcing rib is formed at the tip of the insertion edge to reflect rain within the connection structure, thereby increasing the waterproofness of the connection part. The board has a sandwich structure, which greatly improves its mechanical strength. The board can be stretched vertically or horizontally. Flatness of the entire wall can be easily obtained. It has the following characteristics.
