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 Tokko No. 51-29339 and Utility Model No. 51-
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. 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 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 recessed part with a gap that strengthens the step part to make the dividing line clearer and to connect 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 present invention proposes a board that has uniform horizontal joint width, no deformation of the decorative surface portion, and has significantly improved waterproofness and three-dimensional appearance.

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 names are Gulfuan, Galvalium Steel Sheet, Super Zinc), and aluminum. Forming a metal plate (including flat plate and embossed plate) made of one type of sheet, aluminum alloy plate, copper plate, etc. by roll or press, or by 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 which are formed to form a sanderch structure. To explain further, the surface material 1 is composed of a long decorative surface part 2 , a male connecting part 7 , a female connecting part 16 , and a gutter-like part 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. , and then folded outward to form a recess 4 with a depth of, for example, about 2 to 10 mm, and a plurality of elongated inclined decorative pieces 6, 6a separated by a stepped part 5 and a stepped piece 3. (hereinafter simply referred to as a decorative piece) and a gap 5a formed at the upper edge of the decorative piece 6a. The size of the gap 5a is the size of the gap that occurs when the surface material 1 is bent, or it is formed arbitrarily, and by more clearly separating the lower end of the step piece 3 and the decorative piece 6a, This enhances the three-dimensional appearance of the decorative surface portion 2 and also reinforces its strength. The decorative surface portion 2 is mainly used to form the surface of the surface material 1 into a step-like shape to promote three-dimensionality and to improve strength. In particular, the recessed portion 4 is effective in clearly forming a dividing line in the stepped portion 5 and making the stepped piece 3 visually larger and more clearly visible. 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). an insertion edge 10 formed from an insert edge 10 (shape); an engagement groove 11 with the insertion edge 10 as the upper end; and an extension portion 1 that protrudes outward from the lower edge 12 of the engagement groove 11.
It is composed of 3. 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 step piece 17 which is bent inward at the lower end of the decorative surface part 2 , an upper edge 18 whose lower edge is bent inward, and a lower edge 19 which is 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. Moreover, the gutter-like part 22 is a space surrounded by the decorative surface part 2 and the male and female connecting parts 7 and 16 ,
It is for filling. Note that the dimensions and angles of each part of the surface material 1 are set as follows. Angle θ ₁ of the decorative pieces 6, 6a with respect to the horizontal line A,
θ ₂ is θ ₁ = θ ₂ , or θ ₁ ≒ θ ₂ , or a somewhat different θ ₁ θ ₂ , and the angles θ 3 and θ ₄ between the decorative pieces 6, 6a and the step pieces 3, ₁₈ are θ ₃ = θ ₄ , or θ ₃ ≒ θ ₄ , for example θ
₃
=90°, the angle θ ₅ between the stepped piece 17 and the upper edge 18 , and the angle θ ₆ of the fitting groove 20 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 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 of the step piece 1 is
The height from the top of 7 to the horizontal line B is h ₄ , step part 5
If the thickness between the back surface and the back material 23 is Δt, and the thickness of the surface material 1 is t, then h ₃ ≒ h ₄ or h ₃ > h ₄ and h ₃
= h ₁ +Δh ₁ +Δt or a height close to it. This means that when board A is installed on frame α as shown in Figure 3, the stepped portion 5 is attached to frame α at the side joint between boards A.
This is to make the height the same, almost the same, or somewhat lower than the height H from the top. 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 gap 5a in the recess 4 is arbitrary, but by making it almost the same as the gap Δh ₂ at the joint between the boards A, as shown in FIG. In order to create _an appearance _that looks _{like it} is composed _of
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., such as asbestos paper, kraft paper, asphalt felt, metal foil (Al, Pb,
Fe), synthetic resin sheet, rubber sheet, cloth sheet,
Consisting of 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 something. In addition, the heat insulating material 24 fills at least the space formed by the back surface of the decorative surface section 2 and the back surface of the female connecting section 16 , and provides the board with heat insulating properties and strength. It is made of a type of material that has functions such as sex. 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 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
4 is mainly a synthetic resin foam, such as a resin for polyurethane foam, a resin for polyisocyanurate foam, a resin for phenol foam, and flame retardants and flame retardant aids (borax, sodium metaborate, calcium carbonate, hydroxide). It is made of one or more of aluminum, antimony trioxide, bentonite, pearlite grains, and shirasu balloons.

Next, a construction example will be explained.

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 nail installation piece 14 of the nth board A ₁ was 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. That is, the horizontal joints are formed to have an appearance that is the same as or somewhat lower than the stepped portions 5 of the boards A ₁ and A ₂ . 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 are in contact with each other, forming a slight gap Δh ₂ therebetween, and forming the stepped portion 5 of the board A.
It is designed to have an appearance very similar to that of In addition, 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, the base part includes a starter (not shown), vertical joints of the wall, and parts such as exit and entry corners (not shown).

This is a board which prevents the decorative surface part 2 from becoming mountain-like during construction.

As described above, according to the board according to the present invention,
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 step portion is provided with a recessed portion having a void, the step difference between the decorative pieces is promoted to be much larger than before, and the entire decorative surface portion 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 extremely easily formed into one piece by utilizing the self-adhesive properties of foaming without an adhesive. It has the following characteristics.
