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 these drawbacks, the present invention forms the decorative surface part in a step-like manner, and provides a hollow 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. To propose a board which has a uniform horizontal joint width, has no deformation of the decorative surface, and has significantly improved waterproofness, three-dimensional effect, and engagement force.

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 25 is integrally filled between the front surface material 1 and the back surface material 24 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 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. , 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. Note that the void 5a
The size of the gap is the size of the gap that occurs when the surface material 1 is bent, or it is arbitrarily formed. By clearly separating the lower end of the stepped piece 3 and the decorative piece 6a, This not only enhances the three-dimensional effect but 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 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). The engagement groove 11 has the insertion edge 10 as its upper end, and the extension portion 13 projects outward from the lower edge 12 of the engagement groove 11. To explain further, the extension part 13 includes a nailing piece 14, a protruding rib 14a whose tip extends parallel to the longitudinal direction, and a reinforcing and raising piece whose end is bent inward in an L-shape parallel to the longitudinal direction. 15 and a tongue piece 16 whose tip is bent inward. The female connecting part 17 includes 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 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. 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 and 6a and the step pieces 3 and 18, _{which are somewhat different, are θ 3 = θ 4} , or θ ₃
≒ θ ₄ , for example θ ₃ = 90°, step piece 18 and upper edge 19
The angle θ ₅ between them and the angle θ ₆ of the fitting groove 21 are determined depending on the angle of the insertion edge 10. Incidentally, the angles θ〓 and θ〓 of the step pieces 3 and 18 with respect to the vertical line B are determined according to θ ₁ and θ ₄ . Further, the heights h ₁ and h ₂ of the step pieces 3 and 18 are the same or almost the same, and the step portion 5
The height from the apex 5b to the horizontal line B is _h3 , the height from the upper end of the stepped piece 18 to the horizontal line B is _h4 , the height of the vertical piece 15a is _h5 , and the height of the protruding rib 14a is _h6 . Then, h ₃ > h ₄ > h ₅ , h ₃ = h ₄ + h ₅ or a height close to it, and h ₆ is about 1 to 3 mm. This means that when board A is installed on frame α as shown in Figure 3, the height H from the frame α of the stepped portion 5 and the horizontal joint between boards A should be the same or almost the same, and the connecting portion This is to strengthen the waterproof and heat-insulating properties. Furthermore, although the height θh ₁ of the cavity 5a of the recessed portion 4 is arbitrary, the third
As shown in the figure, by setting the gap θh ₂ at the joint between the boards A to be almost the same, the appearance appears as if the entire wall is made up of the same stepped portion 5, so θh ₁ =θh ₂ or θh ₁ ≒ θh ₂ .
Further, the backing material 24 described above is for covering at least the backside of the heat insulating material 25, and serves to strengthen the mechanical strength of the board itself, and also to provide a noncombustible sheet.

Further, the heat insulating material 25 is a space formed by at least the back surface of the decorative surface section 2 and the back surface of the female connecting section 17 (in the figure, up to the back surface of the extension section 13).
It is filled with a material that gives the board heat insulation properties, and is made of a type of material that has secondary functions such as adhesiveness and nonflammability. Specifically, it is made of one type of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., and is discharged as a molded body or raw material.
It consists of one type of material, such as one that can be molded, solidified, or self-adhesive. In addition, when using a molded body, 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, 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 25 is aluminum kraft paper, and the heat insulating material 25 is a raw material for polyisocyanurate foam discharged between the surface material 1 and the back material 24. , 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 21 of the female connecting portion 17 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 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 6 of the board A ₁ are in contact, and a slight gap θh ₂ is formed therebetween, creating an appearance that closely resembles 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. Note that 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). In addition, the board

As mentioned 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. Insulating material is filled as the core material of the board, and protruding ribs are inserted into the insulating material.
Moreover, since the side joints are double layered with insulation material, a wall with excellent insulation properties can be formed. 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.
