Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a siding board (hereinafter simply referred to as a board) useful for forming horizontal walls in buildings and structures. (Prior art and problems) Examples of this type of board that have been used in the past include Japanese Patent Publication No. 51-29399 and Utility Model Publication No. 51-29399.
These include No. 11882 and Utsuko 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 drawbacks of lacking three-dimensionality, waterproofness, heat insulation, workability, and economic efficiency. (Purpose of the invention) In order to eliminate these drawbacks, the present invention forms the decorative surface part in a step-like shape, makes the board wide with multiple steps, and provides decorative ribs and gaps in the step part to emphasize the difference in steps. , the dividing line is made clearer, and the structure closely resembles the appearance of the joint section consisting of male and female type connecting parts, so that the board can be easily installed by one worker without requiring any skill. It is possible,
Furthermore, the present invention proposes a board that has a uniform horizontal joint width, has no deformation of the decorative surface, and has significantly improved waterproofness, three-dimensional appearance, and engagement force. (Structure of the invention) The board according to the invention will be described below using drawings. That is, as shown in FIG.
Metals made of one type of metal (including flat plates and embossed plates) such as nickel alloy plated steel plates, aluminum/zinc alloy plated steel plates (product names: Gulfuan, Galvalume steel plate, Super Zinc), aluminum plates, aluminum alloy plates, copper plates, etc. A heat insulating material 23 is filled between a surface material 1 and a back surface material 22 formed by a method such as roll molding, press molding, or extrusion molding to form a sandwich structure. To explain further, as shown in FIG .
4. That is, the decorative surface portion 2 includes a stepped piece 3 formed with at least one step as shown in the figure parallel to the longitudinal direction at an arbitrary position (approximately the center in the figure) on the surface of a long board, and its lower end 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 pieces (hereinafter simply referred to as decorative pieces) separated by the stepped pieces 3. ) 2a, 2b,
It consists of a gap 5a provided between the lower end 4a of the decorative rib 4 and the upper edge of the decorative piece 2b. The size of the gap 5a is the same as the size of the gap that occurs when the board A is bent, or it is formed arbitrarily. This not only enhances the three-dimensional effect of the material, but also reinforces its strength. The decorative surface portion 2 mainly forms the surface of the surface material 1 in a step-like manner to promote a three-dimensional effect and is useful for improving strength. In particular, cosmetic rib 4
This is effective for clarifying the dividing line of the step portion 5 and making the step piece 3 appear larger visually. In addition, the male connecting part 6 includes a groove part 7 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 (pipe-shaped in the figure) formed at the tip of the groove part 7. 8, an engagement groove 10 with the insertion edge 9 as an upper edge, an extension 12 projecting outward from the lower edge 11 of the engagement groove 10, and an extension 1
The tongue piece 13 has a tongue piece 13 bent in a flute shape at the tip of the tongue piece 2. The female connecting part 14 has a stepped piece 15 which is bent inward at the lower end of the decorative surface part 2 , a decorative rib 16 whose tip protrudes briefly outward, and then bent inward.
and the lower edge piece 17 of the decorative rib 16 is the upper edge,
A fitting groove 18 whose tip is bent outward to fit the insertion edge 9, and a tongue piece 2 whose lower edge 19 is bent inward.
0, and the lower edge 19 is inserted into the engagement groove 10 at the same time as the insertion edge 9 is fitted into the engagement groove 18, and serves to further strengthen the engagement force. In addition, the decorative ribs 16 are used to make the appearance of the joint between the boards A closely resemble the stepped portion 5 when constructed, and are also used as decorative pieces 2a of the lower board.
It also functions to cover the upper edges of the joints and strengthen waterproofness at the joints. The dimensions and angles of each part of the surface material 1 are set as follows. In other words, the step pieces 3, 1
5 is h ₁ , h ₂ , the width of decorative ribs 4 and 16 is W ₁ ,
W ₂ , the angles between the step pieces 3, 15 and the decorative pieces 2a, 2b are θ ₁ , θ ₂ , the decorative ribs 4, 16 and the step pieces 3, 15
The angles of θ ₃ and θ ₄ are the angles of the decorative piece 2a and the horizontal line A, respectively.
If the angles of 2b are θ ₅ and θ ₆ , then h ₁ = h ₂ , or h ₁ ≒ h ₂ W ₁ = W ₂ , or W ₁ ≒ W ₂ 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 . This is done so that when board A is installed on the wall base α as shown in Fig. 3, the connecting part of boards A ₁ and A ₂ closely resembles the external appearance of the stepped part 5, and the whole is made by the same stepped part 5. 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 21 is a space surrounded by the decorative surface portion 2 and the male and female connecting portions 6 and 14 , and is filled with a heat insulating material 23. Further, the back material 22 described above is for covering at least the back surface of the heat insulating material 23, and not only strengthens the mechanical strength of the board A itself, but also serves as a noncombustible sheet, a waterproof membrane, a heat shield sheet, a water absorbing sheet, a soundproof sheet, It functions as a member of release sheets, packing materials, reinforcing sheets, etc., such as asbestos paper, metal foil (A, Fe,

(Effects of the invention) As mentioned above, according to the board according to the invention, since at least one stepped part is formed on the decorative surface, the strength is sufficiently reinforced, and even if the board is made wide, the width is small in appearance. Because it is made up of multiple narrow boards, it does not become mountain-like. By providing decorative ribs and gaps in the stepped parts, the difference in level between the decorative pieces is much larger than before.
The entire decorative surface area has a three-dimensional appearance. Since the male and female connecting parts are formed into the above-mentioned drop-in structure, it can be easily installed by one person, and
The joint width (horizontal) can be formed constant. 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, the appearance of the stepped portion and the side joints are almost the same, creating a unified horizontal line, making it possible to form a wall with a beautiful appearance and a rich three-dimensional effect. Since the decorative rib of the female connecting part covers the upper end of the upper decorative piece in the joint part, the waterproofness of the joint part is improved. Since the board is wide, it is easy to install, and the width of the material can be used effectively, making it highly economical. 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. When synthetic resin foam is used as a heat insulating material, it is lightweight and has excellent heat insulation properties, and the constituent materials can be formed into one piece very easily without adhesives by utilizing the self-adhesive properties of foaming. There is.
