Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a siding board (hereinafter simply referred to as a board) useful for forming horizontal walls for the interior and exterior of buildings and structures. Examples of this type of board that have been used in the past include A Special Publication No. 51-29339 and B Utsuko No. 51-
There are No. 11882 and C-Jitsukō No. 54-26649. However, the biggest drawback of this type of board is that the decorative surface becomes mountain-like, and walls formed using it have the appearance of a continuous mountain. In other words, when the decorative surface of the board becomes mountain-like, it not only has poor aesthetics, but also is difficult to install, and there are disadvantages such as a lack of waterproofness at the connecting portion and the possibility of the board coming off. In addition, many of these types of boards have a hanging structure, which has the disadvantage of uneven joint width due to construction. Furthermore, the decorative surface of this type of board is flat (including embossed) by design, and
It was just a step or unevenness, lacking a three-dimensional effect, and the working width was small, so it had the disadvantage of lack of workability. In addition, boards of this kind that have a drop-in type connection structure are also known, but these have the disadvantages of lacking three-dimensionality, waterproofness, heat insulation, workability, and economy. In order to eliminate such drawbacks, the present invention forms the decorative surface part in a step-like manner, and provides a hollow part in the step part to strengthen the step, thereby making the dividing line clearer and making the board The appearance of the joints in the male and female joints that are formed when they are connected is structured to closely resemble the step appearance of the decorative surface area, making it easy to install the boards by one worker without requiring any skill. The present invention proposes a board that has a uniform horizontal joint width, no deformation of the decorative surface, and has significantly improved waterproofness and three-dimensionality. The board according to the present invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the board A is made of, for example, a surface-treated steel sheet, a steel sheet plated with a zinc-nickel alloy, an aluminum-zinc alloy plated steel sheet (product name: Gulfuan, Galvalium Steel Sheet, Super Zinc), or an aluminum sheet. ,
A metal plate (including flat plate and embossed plate) made of one type of aluminum alloy plate, copper plate, etc. is formed into the shape shown in Figure 2 by roll or press forming, or by one type of extrusion molding. A heat insulating material 25 is integrally filled between the surface material 1 and the back material 24 to form a sanderch structure. To explain further, the surface material 1 is composed of a long decorative surface portion 2 , a male connecting portion 7 , a female connecting portion 17 , and a gutter-like portion 23 filled with a heat insulating material 25. That is, the decorative surface part 2 is formed by forming at least one level step piece 3 at an arbitrary position (in the center in the figure) on the surface of the elongated plate, parallel to the longitudinal direction of the surface, and extending the lower end of the step piece 3 inward. Next, a plurality of elongated inclined decorative pieces 6, 6a ( (hereinafter simply referred to as a decorative piece) and a void formed on the upper edge of the decorative piece 6a 5a
It is composed of. Note that the size of the space 5a is the size of the space created when the surface material 1 is bent, or it is arbitrarily formed. This enhances the three-dimensional appearance of the decorative surface portion 2 , makes the appearance of the step portion 5 closely resemble the appearance of the horizontal joint portion, and also reinforces the strength. That is, the decorative surface portion 2 mainly serves to enhance the three-dimensional appearance of the surface of the surface material 1 formed in a step-like manner, and also to improve the strength. In particular, the recessed portion 4 clearly forms a dividing line in the stepped portion 5, making the stepped piece 3 visually larger and more clearly visible.
It is possible to closely resemble the appearance of the horizontal joint portion when the board A is connected to the board A, and is effective in giving the impression that the decorative pieces 6 and 6a are independent decorative surfaces. In addition, the male connecting part 7 has a groove part 8 which is recessed in the upper edge of the decorative surface part 2 in parallel with the longitudinal direction to prevent rain and capillary phenomenon, and a reinforcing rib 9 (in the figure, a reinforcing rib 9 is formed at the tip of the groove part 8). The engagement groove 11 has the insertion edge 10 as its upper end, and the extension portion 13 projects outward from the lower end 12 of the engagement groove 11. To explain further, the extension part 13 includes a nailing piece 14, a reinforcing/heightening piece 15 whose tip is bent inward in an L-shape parallel to the longitudinal direction, and a tongue piece 1 whose tip is bent inward.
6. The female connecting part 17 has a stepped piece 18 which is bent inward at the lower end of the decorative surface part 2 , an upper edge 19 which is bent inward at its lower edge, and a lower edge 20 which is formed by bending its tip outward. It is formed from a fitting groove 21 into which the insertion edge 10 is fitted and a tongue piece 22 with the tip of the lower edge 20 bent inward, and the lower edge 20 is inserted into the engagement groove 11 to increase the engagement force. It helps to strengthen the. Further, the gutter-like portion 23 is a space surrounded by the decorative surface portion 2 and the male and female connecting portions 7 and 17 , and is filled with a heat insulating material 25. Note that the dimensions and angles of each part of the surface material 1 are set as follows. Makeup piece 6,6
The angles θ _{1 and θ 2} of a with respect to the vertical line A are θ ₁ =θ ₂ , or θ ₁ ≒θ ₂ , or somewhat different θ ₁ θ ₂ , and the angles of the step pieces 3 and 18 with respect to the vertical line A are θ ₃ and θ ₄ is θ ₃ =
θ ₄ or θ ₃ ≒ θ ₄ , for example θ ₃ = 90°, step piece 1
The angle θ ₅ between the insertion groove 8 and the upper edge 19 and the angle θ ₆ of the fitting groove 21 are determined according to the angle of the insertion edge 10. Further, the heights h ₁ and h ₂ of the step pieces 3 and 18 are the same or almost the same, and the height h ₃ from the apex 5b of the step part 5 to the horizontal line B, and the height from the upper end of the step piece 18 to the horizontal line B If the height is h ₄ and the height of the vertical piece 15a is h ₅ , then h ₃ > h ₄ > h ₅ and h ₃ = h ₄ + h ₅ or a height close to it. This is because when the board A is installed on the frame α as shown in FIG. 3, the height H of the stepped portion 5 and the horizontal joint between the boards A from the frame α is the same or almost the same. Furthermore, the sky of the depression 4 5a
The height Δh ₁ is arbitrary, but by making it almost the same as the height Δh ₂ at the joint between the boards A as shown in Fig. 3, the entire wall is composed of the same stepped portion 5. Δh ₁ =
Δh ₂ or Δh ₁ ≒Δh ₂ . moreover,
The above-mentioned surface material 24 is for covering at least the back side of the heat insulating material 25, and strengthens the mechanical strength of the board itself, as well as a noncombustible sheet, a waterproof membrane,
It functions as a component of heat shielding sheets, waterproof sheets, soundproof sheets, release sheets, packing materials, reinforcing sheets, etc. For example, asbestos paper, kraft paper, asphalt felt, metal foil (Al,
Pb, Fe), synthetic resin sheet, rubber sheet, cloth sheet, glass cloth, or a combination of one or more of these, or a sheet that has been treated with waterproofing, flame retardant, etc. , or one of the metal plates mentioned above. Further, the heat insulating material 25 is at least the decorative surface portion 2
It fills the space formed by the back surface of the board and the back surface of the female connecting part 17 (up to the back surface of the extension part 13 in the figure) to give the board heat insulation properties, and secondary properties such as adhesiveness and nonflammability. It is made of a type of material that has the following functions. Specifically, it consists of one type of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., and it is a molded body or one that is discharged with raw materials, molded, solidified, or self-adhesive. It consists of seeds.
Note that when a formed body is used, an adhesive (not shown) is required between the front material 1 and the back material 24. To explain further, the heat insulating material 25 is mainly made of synthetic resin foam, such as resin for polyurethane foam, resin for polyisocyanurate foam, resin for phenol foam, and flame retardants and flame retardant aids (borax, sodium metaborate). , calcium carbonate, aluminum hydroxide, antimony trioxide, bentonite, pearlite grains, and shirasu balloons.Next, an example of construction will be explained.As shown in Figure 1.

Since at least one stepped portion is formed in the decorative surface portion, the strength is sufficiently reinforced and the decorative surface does not become mountain-like. Since the hollow part is provided in the stepped part, the difference in level between the decorative pieces is much larger than before, and the entire decorative surface part has an appearance rich in three-dimensional effect. Since the male and female joints are formed into the above-mentioned drop-in structure, it can be easily carried out by one person, the joint width (horizontal) can be kept constant, and it is highly waterproof. No skill is required to connect the boards, and construction can be performed with extremely high efficiency. The board has a sanderch structure, which improves its strength. When a wall is formed from boards, the appearance of the stepped portion and the side joint portion are at least almost the same, so a wall with a beautiful appearance and a rich three-dimensional effect can be formed. The board is filled with a heat insulating material as a core material, and the side joints are double layers of heat insulating material, making it possible to form a wall with excellent heat insulation properties.
Because the surface material is wide, it is easy to install, and the width of the material can be used effectively, making it highly economical. When synthetic resin foam is used as a heat insulating material, it is lightweight and has excellent heat insulating properties, and the constituent materials can be formed into one piece very easily without an adhesive by utilizing the self-adhesive properties of foaming. It has the following characteristics.
