[Problem that the idea aims to solve]

However, the biggest drawback of this type of board is that the decorative surface becomes mountain-like. The wall formed using this material had the appearance of a continuous mountain. Let me rephrase it For example, if the decorative surface of the board becomes mountain-like, it not only looks bad, but is also difficult to install. Moreover, there were disadvantages such as the connection part lacked waterproofness and could come apart. Also, this Many of the seed boards have a hook structure, which has the disadvantage of uneven joint width due to construction. It was. Furthermore, the decorative surface of this type of board is flat (including embossed) by design. However, it is just a step or unevenness, which gives it a three-dimensional effect and has a small working width. Therefore, there was a disadvantage in that construction workability was lacking. In addition, on this type of board, Boards with a toshikomi-type connected structure are also known, but they have a three-dimensional feel, waterproofness, and insulation properties. However, there were drawbacks such as lack of workability and economic efficiency.

[Means to solve the problem]

In order to eliminate these drawbacks, the present invention forms the decorative surface part in a step-like manner, and the board The height difference is made wide with multiple steps, and decorative ribs and gaps are installed in the step part to emphasize the difference in steps. This makes the dividing lines clearer, and also reduces the appearance of the joints consisting of male and female joints. With a similar structure, the board can be installed by a single worker without the need for skill. Furthermore, the joint width is uniform, there is no deformation of the decorative surface, and it is waterproof. We propose a board with significantly improved insulation, three-dimensional appearance, and engagement force.

【Example】

The board according to the present invention will be described below with reference to the drawings. In other words, the above box As shown in Figure 1, for example, code A is a surface-treated steel sheet or a steel sheet coated with a zinc-nickel alloy. Plated steel sheets, aluminum/zinc alloy plated steel sheets (product names: Galfan, Galvaliu) (super zinc), aluminum plate, aluminum alloy plate, copper plate, etc. Metals consisting of seeds (including flat plates and embossed plates) are rolled, press-formed, and A heat insulating material 2 is formed between the surface material 1 and the back material 25 formed by a method such as extrusion molding. 6 to form a sandwich structure.

[0006] To explain further, the surface material 1 has a long decorative surface portion 2 as shown in FIG. 2(a). It is formed from a male type connecting part 6 and a female type connecting part 17. In other words, the cosmetic area 2 is shown parallel to the longitudinal direction at an arbitrary position on the surface of a long board (approximately the center in the figure) The step piece 3 with at least one step formed thereon and its lower end are shortened outward, for example. A stepped portion 5 formed from a decorative rib 4 that protrudes by about 2 to 20 mm and then bends inward. and a plurality of long inclined decorative surfaces divided by step pieces 3 (hereinafter simply referred to as decorative pieces). ) 2a, 2b, and the lower edge 4a of the decorative rib 4 (approximately 1 width of the decorative rib 4 in the figure) /2) and a gap 5a provided between the upper edge of the decorative piece 2b. Na The size of the gap 5a is the size of the gap that occurs when board A is bent, or It is formed arbitrarily, and the purpose is to make the decorative rib 4 and the decorative piece 2b more clear. Therefore, it not only promotes the three-dimensional effect in the stepped portion 5 but also reinforces the strength. . The decorative surface section 2 mainly forms the surface of the surface material 1 in a step-like manner to promote a three-dimensional effect. Together, they help improve strength. In particular, the decorative ribs 4 are This is effective for making the dividing line clear and making the step piece 3 look larger visually.

[0007]The male connecting part 6 also has a groove part 7 which is recessed in the upper edge of the decorative surface part 2 parallel to the longitudinal direction to prevent rain and capillary phenomenon, and a reinforcing rib (not shown in the figure) formed at the tip of the groove part 7. It consists of an insertion edge 9 formed from a pipe-shaped (pipe-shaped) 8, an engagement groove 10 with the insertion edge 9 as an upper edge, and an extension part 12 that projects outward from the lower edge 11 of the engagement groove 10. be. To explain further, the extension part 12 extends inward from the nailing piece 13 and its tip, or from the protrusion 14 that protrudes in parallel to the longitudinal direction in the middle (not shown) of the nailing piece 13 and its end edge. It is formed from a reinforcing/heightening piece 15 formed in a character shape and a tongue piece 16 whose tip is bent inward. To explain further, as shown in FIG. 3, when the protrusion 14 is installed, it bites into the back surface of the heat insulating material 26 near the female connecting part 17 of the upper board A ₂ , and the gap between the boards A ₁ and A ₂ increases. This helps strengthen the engagement force.

[0008] The female connecting part 17 has a stepped piece 18 bent inward at the lower end of the decorative surface part 2 and its tip. A decorative rib 19 that protrudes briefly outward and then bends inward, and a lower part of the decorative rib 19. A fitting groove 21 having the edge 20 as the upper edge and bending its tip outward to fit the insertion edge 9; The lower edge 22 is formed from an inwardly bent tongue piece 23; It is inserted into the engagement groove 10 and serves to further strengthen the engagement force.

[0009]The dimensions and angles of each part of the surface material 1 are set as follows. That is, as shown in FIG. 2(b), the angles of the step pieces 3 and 18 with respect to the base line A when board A is constructed are θ ₁ and θ ₂ , respectively, and the angles of the step pieces 3 and 18 with respect to the decorative pieces 2a and 2b are If the angles are θ ₃ and θ ₄ and the angles between the decorative ribs 4 and 19 and the step pieces 3 and 18 are θ ₅ and θ ₆ , then θ ₁ = θ ₂ , or θ ₁ ≒ θ ₂ θ ₃ = θ ₄ , or θ ₃ ≒ θ ₄ θ ₅ = θ ₆ , or θ ₅ ≒ θ ₆ . Also, the widths of the decorative ribs 4 and 19 are W ₁ and W ₂ , the heights of the step pieces 3 and 18 are h ₁ and h ₂ , and the height from the vertices 3a and 18a of the step pieces 3 and 18 to line A is h ₃ , h ₄ , the relationship is W ₁ =W ₂ , or W ₁ ≒W ₂ h ₁ =h ₂ , or h ₁ ≒h ₂ h ₃ =h ₄ , or h ₃ ≒h ₄ .

[0010] This is so that when the board _A is installed on the wall base α as shown in _FIG . This is to create an appearance that looks structured, to form unified lines on the wall surface, and to form a wall with a beautiful appearance. Further, the gutter-like portion 24 is a space surrounded by the decorative surface portion 2 and the male and female connecting portions 6 and 17, and is filled with a heat insulating material 26.

[0011] Furthermore, the above-mentioned back material 25 is used to cover at least the back surface of the heat insulating material 26. In addition to strengthening the mechanical strength of Board A itself, it also has non-combustible sheets, waterproof membranes, Heat shielding sheets, water absorption sheets, soundproofing sheets, release sheets, packing materials, reinforcing sheets For example, asbestos paper, metal foil (Al, Fe, Pb), one type of synthetic resin sheet, rubber sheet, cloth sheet, glass cloth, Or a combination of one or more of these, or for these sheets Is it something that has been treated to make it waterproof or flame retardant, or one of the metal plates mentioned above? It is made up of

0012 Further, the heat insulating material 26 extends at least to the gutter-like portion 24 (to the back surface of the extension portion 12 in the figure). It is filled with heat-insulating properties to board A itself, and secondary properties include adhesive properties and non-combustibility. It is made of one type of material that has the following functions. Specifically, synthetic resin foam , rock wool, glass wool, sheathing board, gypsum board, wood wool cement Consisting of one type of plate, etc., which is discharged with raw materials, molded, hardened, and self-adhesive, or is made of one type such as a molded body. In addition, when using a molded body, a heat insulating material An adhesive (not shown) is required between 26, the front material 1, and the back material 25. Further explanation Then, the heat insulating material 26 is mainly made of synthetic resin foam, such as polyurethane foam. resins for polyisocyanurate foams, resins for phenolic foams, and flame retardants, flame retardant aids (borax, sodium metaborate, calcium carbonate, hydroxide). aluminum chloride, antimony trioxide), bentonite, pearlite grains, shirasuba It consists of something to which one or more types of runes are added.

Next, a construction example will be explained. Now assume that boards A ₁ and A ₂ as shown in FIG. 1 are laid horizontally as shown in FIG. 3 to form an exterior wall. In addition, for boards A ₁ and A ₂ , the surface material 1 is a 0.27 mm color steel plate, the back material 25 is aluminum kraft paper, and the heat insulating material 26 is a material for polyisocyanurate foam that is discharged between the surface material 1 and the back material 25. It is then reacted, foamed, hardened, and then cured and integrated. Therefore, the nailing piece 13 of board A ₁ of the nth stage is attached to the wall base α consisting of main pillars, studs, waterproof sheets, etc. (the figure shows the wall base when no waterproof sheets are used) through β. Fix it. Next, the fitting groove 21 of the female connecting portion 17 of the n+1-th board A ₂ is fitted into the insertion edge 9 of the male connecting portion 6 of the board A ₁ to form a joint as shown in FIG. It is something to do. That is, the joint portions are formed to have the same appearance as the step portions 5 of the boards A ₁ and A ₂ . In other words, the female connecting portion 17 of the board A ₂ and the upper end of the decorative piece 2 a of the board A ₁ come into contact, forming a slight gap B therebetween to create an appearance similar to the stepped portion 5 of the board A. It was designed so that it could be formed. Furthermore, in order to form the entire outer wall, it is sufficient to carry out the steps described above from the base to the girder. It is necessary to use a starter (not shown) for the base, and caulking material and accessories for vertical joints, exits, and corners of the wall (not shown).

[Effect of the idea]

As described above, according to the board according to the present invention, there is at least one step in the decorative eye area. Because the step part is formed, the strength is sufficiently reinforced, and even if the board is made wide, it will not fit outside. It looks like it is made up of multiple boards, so it looks like a mountain. Never. Because we have provided decorative ribs and gaps in the step part, the difference in level between the decorative pieces is smaller than before. The effect is much greater, giving the entire cosmetic surface a three-dimensional appearance. male, female Since the connecting part is formed into the drop-in structure described above, it can be easily installed even by one person, and is easy to install. First, the joint width (horizontal) can be formed constant. Requires skill to connect boards It can be constructed with extremely high efficiency. Strong because the board has a sandwich structure. degree will improve. When forming a wall, the appearance of the step and joints should be almost the same. This creates a unified line between the steps and joints, creating a beautiful appearance and three-dimensional feel. The wall is rich in Because the board is wide, it is easy to install, and the width of the material can be reduced. It is highly economical because it can be used effectively. Insulating material is filled as the core material of the board. At the same time, the protrusions dig into the back side of the insulation material, and the joint area is double layered with insulation material. Because it forms a layer, it can form walls with excellent insulation and waterproof properties. Synthetic resin for insulation When foam is used, it is lightweight, has excellent heat insulation properties, and has no adhesive when foaming. Using self-adhesive properties, components can be formed into one piece very easily, and the board can also be constructed. This creates a continuous triangular space between the board and the wall base, making it easy to It has characteristics and effects such as creating a curl effect.
