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 has a hilly shape, and a wall formed using this has the appearance of a continuous mountain. In other words, when the decorative surface of the board becomes shabby, it not only has poor aesthetics, but also is difficult to install, lacks waterproofness at the joints, and has disadvantages such as detachment. Additionally, this type of board often has 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 disadvantages in that they lack 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 recessed part with a hollow to emphasize the difference in the step, thereby making the dividing line clearer and connecting the boards. To create a structure in which the appearance of the joints in the male and female connecting parts that are formed when the board is made is similar to the appearance of the step in the decorative surface part, and the board can be easily installed by one worker without requiring any skill. The purpose of the present invention is to propose 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. ,
Forming a metal plate (including flat plate and embossed plate) made of one type of aluminum alloy plate, copper plate, etc. by roll or press, or by one type of extrusion molding into the shape shown in Figure 2. A heat insulating material 24 is integrally filled between the front surface material 1 and the back surface material 23 to form a sandwich structure. To explain further, the surface material 1 has an elongated decorative surface portion 2.
It is composed of a male connecting portion 7 , a female connecting portion 16 , and a gutter-like portion 22 filled with a heat insulating material 24.
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. , then a plurality of long inclined decorative pieces 6 , 6a ( (hereinafter simply referred to as a decorative piece) and a cavity 5a formed in a recessed portion at one end edge of the decorative piece 6a. In addition, the size and depth Δd of the opening Δh ₁ of the sky 5a are the surface material 1.
It is the size of the gap that occurs when folding or is formed arbitrarily, and by more clearly distinguishing between the lower end of the step piece 3 and the decorative piece 6b, it promotes the three-dimensional effect of the decorative surface part 2 . , which also reinforces the 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, the recessed portion 4 clearly forms a dividing line in the stepped portion 5 ,
This is effective in making the step piece 3 visually larger and more clearly visible, and when Δd is 5 mm or more, the heat insulating material 24 is held between the boards and the heat insulating material 24 is strengthened. In addition, the male connecting part 7 has a concave part 8 which is recessed parallel to the longitudinal direction at one end of the decorative surface part 2 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 concave part 8) The insert edge 10 formed from the insert edge 10 and the insert edge 10 formed from
The upper edge of the engagement groove 11 and the lower edge 12 of the engagement groove 11
and an extension portion 13 projecting outward. To explain further, the extension part 13 is formed from a nailing piece 14 and a tongue piece 15 whose tip is bent outward. The female connecting part 16 has a stepped piece 17 with the other end of the decorative surface part 2 bent inward, an upper edge 18 with its lower end bent inward, and a lower edge 19 formed by bending its tip outward. It is formed from a fitting groove 20 into which the insertion edge 10 is fitted and a tongue piece 21 with the tip of the lower edge 19 bent inward, and the lower edge 19 is inserted into the engagement groove 11 to increase the engagement force. It helps to strengthen the. Further, the gutter-like portion 22 is a space surrounded by the decorative surface portion 2 and the male and female connecting portions 7 and 16 , and is filled with a heat insulating material 24. Note that the dimensions and angles of each part of the surface material 1 are set as follows. The angles θ ₁ and θ ₂ of the decorative pieces 6 and 6a with respect to the horizontal line A are θ ₁ =θ ₂ or θ ₁ ≒θ ₂ ,
Alternatively, the angles θ _{3 and} θ 4 between the decorative pieces 6, 6a and the step pieces 3, 17 are somewhat different θ ₁ θ ₂ , or θ ₃ =θ ₄ , or θ ₃ ≒θ ₄ , for example, θ ₃ =90°, Step piece 17 and upper edge 18
The angle θ ₅ between them and the angle θ ₆ of the fitting groove 20 are determined depending on the angle of the insertion edge 10. Further, the heights h ₁ and h ₂ of the step pieces 3 and 17 are the same or almost the same, and the height from the apex 5b of the step part 5 to the horizontal line B is h ₃ , and the height from the upper end of the step piece 17 to the horizontal line B is If the height of is h ₄ , the thickness between the back surface of step portion 5 and back material 23 is Δt, and the thickness of surface material 1 is t, then h ₃ > h ₄ and h ₃ =
The height is h ₁ +Δh ₁ +Δt or close to it. This means that when board A is installed on frame α as shown in Figure 3, the height difference 5 will be the same, almost the same, or slightly lower than the height H of the horizontal joint between boards A from frame α. This is to make it clearer. Note that the difference in height between the stepped portion 5 and the horizontal joint portion is approximately Δt,t. moreover,
The height Δh ₁ of the space 5a in the recess 4 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 can be made to have the same height. In order to create an appearance that looks like it is constituted by the stepped portion 5 , either Δh ₁ =Δh ₂ or Δh ₁ ≒Δh ₂ , Δh ₁ >
It is preferable to set it to Δh ₂ . Furthermore, the back material 23 described above is for covering at least the back surface of the heat insulating material 24, and not only strengthens the mechanical strength of the board itself, but also serves as a noncombustible sheet, a waterproof membrane, a heat shield sheet, a water absorbing sheet, a soundproof sheet, and a peelable sheet. It functions as a member of 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,
One type of glass cloth, a combination of one or more of these types, a sheet of this type treated with waterproofing, flame retardant, etc., or one type of metal plate as described above. It is. Further, the heat insulating material 24 includes at least the decorative surface portion 2.
It is a type of material that fills the space formed between the back surface of the board and the back surface of the female connecting part 16 to give the board heat insulation and strength, and also has secondary functions such as adhesiveness and nonflammability. It consists of Specifically, synthetic resin foam, rock wool, glass wool,
It consists of one type of sheathing board, gypsum board, wood wool cement board, etc., and one type of molded body, or one type of material that is discharged from raw materials, molded, solidified, and self-adhesive. Note that when a molded body is used, an adhesive (not shown) is required between the front material 1 and the back material 23. To explain further, insulation material 2
As No. 4, synthetic resin foams are mainly used, such as resins for polyurethane foam, resins for phenol foam, resins for polyisocyanurate foam,
Phenol foam resins, and those to which one or more of flame retardants, flame retardant aids (borax, sodium metaborate, calcium carbonate, aluminum hydroxide, antimony trioxide), bentonite, perlite grains, and shirasu balloons are added, etc. It consists of Next, a construction example will be explained. Assume now that boards 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 , the surface material 1 is a 0.27 mm color steel plate, the back material 23 is aluminum kraft paper, and the heat insulating material 24 is a raw material for polyisocyanurate foam discharged between the surface material 1 and the back material 23. , reacted and foamed, and then cured and integrated. Therefore, the nailing piece 14 of the nth board A ₁ is attached to the wall base consisting of main pillars, studs, waterproof sheets, etc. (the figure shows the wall base when no waterproof sheet is used) α.
is fixed through nail β. Next, insert the fitting groove 20 of the female connecting portion 16 of the n+1st stage board A ₂ into the board.
Fit into the insertion edge 10 of the male connecting part 7 of _A1 , and
This forms a joint as shown in the figure. In other words, is the horizontal joint part the same as board A ₁ , A ₂ step part 5 ?
It is formed to have a somewhat low appearance.
In other words, the female connecting portion 16 of the board A ₂ and the upper end of the decorative piece 6 of the board A ₁ come into contact and form Δh ₂ there for a short time, resulting in an appearance very similar to the stepped portion 5 of the board A. It is designed to form a 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. In addition, a starter (not shown) is attached to the base.

Boards A and G, which are divided into two parts, have two stepped portions 5. Boards A and H have a fitting groove 20 as shown in the figure, which improves the waterproofness of the connection part, the engagement force, and the construction. This is board A with improved properties. As described above, according to the board according to the present invention,
Since at least one stepped portion of the decorative surface portion is formed, the strength is sufficiently reinforced and the decorative surface does not become uneven. 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 have 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 work with, 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 extremely easily formed into one piece by utilizing the self-adhesive properties of foaming without an adhesive. There are other effects.
