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 of buildings and structures.

[Conventional technology]

This type of board that has traditionally been used is Special Publication No. 51-29339, Utility Model Publication No. 51-11882,
There is Jikko No. 54-26649. however,
There were various problems with the above board. In other words, if rainwater is blown by the wind on the board (cladding board), the rainwater will leak to the back side because it is simply a connecting structure between flat plates, corroding the trunk line and pillars, and adding moisture to the room and closet. There was a drawback. In addition, because the length of the sloped part of the lower edge to the rising part of the board is long, it is weak in tensile force and has the disadvantage that only an exterior without joints can be formed. Furthermore, although the exterior was originally without joints, due to the skill of the builder, the exterior was made up of joints of varying widths, some without joints, some with joints, and there was a risk of injury at the rising parts during construction. In addition, this board has a complicated side surface shape, making it difficult and expensive to mold.Furthermore, there are no reinforcing ribs on the flat part, so warping, twisting, etc. appear on the decorative surface, spoiling the aesthetic appearance. It was hot. In addition, all of the boards do not have a backing material, so condensation forms on the back of the decorative surface, causing rust, and the wall itself lacks heat insulation, fireproofing, and soundproofing properties, and the decorative surface cannot be prevented from deforming. The problem was that it was easily deformed and lacked connection strength. Among this type of boards, boards with a drop-in type connection structure are also known, but these have disadvantages of being inferior in waterproofness and workability. In addition, some boards of this type have a decorative groove formed almost in the center of the decorative surface, but the boundary between the top and bottom surfaces of the decorative groove is not clear, and the areas where the surface materials contact each other at the joints are known. There is a difference between
It was not possible to form a uniform pattern on the wall, which resulted in poor aesthetics.

[Purpose of invention]

In order to eliminate the above-mentioned drawbacks, the present invention has a longitudinal section along the longitudinal direction of the decorative surface in the shape of a scalene trapezoid consisting of a top surface, a bottom surface, and an inclined surface, and a recessed portion between the top surface and the bottom surface. At least one decorative groove is formed to closely resemble the joint created by installing boards, creating a unified horizontal line with a three-dimensional effect on the wall, giving it a beautiful appearance, and reducing the warping of the decorative surface. , prevents twisting and twisting, and
In addition to making the board wider, the design of the board is improved, and the construction of the board is easy and can be done by one worker without any skill, and the engagement strength of the connecting part and waterproofing are improved. We are proposing a board that greatly promotes sex.

[Structure of the idea]

Hereinafter, typical embodiments of the board according to the present invention will be described in detail with reference to the drawings. That is, FIG. 1 is a perspective view showing the above-mentioned board A, and 1 is a surface material, such as a surface-treated steel plate, a steel plate plated with a zinc-nickel alloy, or an aluminum-zinc alloy plated steel plate (product name: Gulfuan, Galvalume). Metal plates (including flat plates and embossed plates) made of one type of metal plate (steel plate, super zinc), aluminum plate, aluminum alloy plate, copper plate, etc., or synthetic resin plates are formed by rolls, presses, or extrusion molding. It is molded by one type. That is,
The facing material 1 is formed from a decorative surface 2, a male connecting portion 5, and a female connecting portion 14. To explain further,
2 is a decorative surface on which at least one decorative groove 3 is formed along the longitudinal direction. As shown in FIG. 2, for example, this decorative groove 3 has a substantially horizontal upper surface 3a, and a recessed portion with a tip of the upper surface 3a bent upward and then folded downward again, with a depth _l1 of, for example, 1 to 10 mm. 4, a bottom surface 3b in which the tip of the recess 4 extends downward almost vertically, and an inclined surface 3c in which the tip of the bottom surface 3b is bent at an angle of θ ₁ and slanted backward, forming a trapezoidal longitudinal section. This is what I did. In particular, since the decorative groove 3 is provided with a recess 4,
The division between the top surface 3a and the bottom surface 3b becomes clear, resulting in a decorative groove 3 with a rich three-dimensional effect, and the surface material 1 at the joint between the male connection portion 5 and the female connection portion 14, which will be described later. The appearance is very similar to the contact line and the shape of the joint, so when a wall is formed using Board A, it creates a uniform horizontal line on the wall, giving the wall a highly aesthetic appearance. can be formed. The shape of the gap 4a of the recess 4 depends on the size of the gap created when the surface material 1 is bent,
Alternatively, it may be formed arbitrarily. Furthermore, one or more decorative grooves 3 are provided along the longitudinal direction of the decorative surface 2, which strengthens the mechanical strength of the board A.
Even if the board A is formed wide, it is prevented from warping, twisting, and flattening, and the decorative surface 2 becomes a flat board A. The male connecting part 5 has an inclined side 6 that slopes backward upward from the upper end of the decorative surface 2, a joint base part 7 that extends the edge vertically upward, and a recessed end parallel to the longitudinal direction. An insertion edge 10 formed from a groove part 8 and a reinforcing rib 9 (pipe-shaped in the figure) for preventing rain return and capillary phenomenon, an engagement groove 11 with the insertion edge 10 as an upper edge, and an engagement groove 11. It is formed from an extension part 12 whose lower edge 11a protrudes outward, and a flap-like tongue piece 13 provided at the tip of the extension part 12. To explain further, the sloped side 6 improves the flow of rainwater, prevents rainwater from accumulating in the side joints, promotes the three-dimensional appearance of the side joints, and is useful for increasing the working width. It is. Further, the joint base portion 7 consists of a vertical surface or a surface slightly inclined inward, and serves as a waterproof base for the horizontal joint portion. Further, the tongue piece 13 is formed by bending the end edge of the extension part 12 into a seam shape, and prevents the end of the extension part 12 from waving. This improves construction safety by preventing accidents and injuries. In addition,
In FIG. 1, the tongue piece 13 is bent in the shape of an upper seam and pinches the end of the backing material 21, but it is also possible to bend it in the shape of a lower seam. Further, the female connecting portion 14 has a so-called horizontal base 15 which is formed by bending the lower end of the decorative surface 2 inward, and an upper edge 16 which is formed by bending the lower edge inward.
Then, bend the tip of the upper edge 16 outward to form the lower edge 1.
7, and is formed from a fitting groove 18 formed in a U-shaped cross section and a tongue piece 19 with the tip of the lower edge 17 bent inward, and the lower edge 17 is formed as shown in FIG. , is inserted into the engagement groove 11 when the insertion edge 10 is fitted into the engagement groove 18, and serves to further strengthen the engagement force and waterproofness. Further, like the tongue piece 13, the tongue piece 19 can be formed in the shape of an upper seam as shown in FIG. . The core material 20 includes at least a decorative surface 2 on the back side of the surface material 1, a male connecting portion 5,
The gutter-shaped portion surrounded by the female connecting portion 14 is filled with the material to provide insulation to the board A.
It is made of a type of material that has secondary functions such as adhesiveness and nonflammability. Specifically, it consists of one type of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., which is discharged as a raw material, molded, hardened, self-adhesive, or a molded body. It consists of seeds. In addition, when using a molded body, an adhesive (not shown) is required between the core material 20, the surface material 1, and the back material 21. To explain further, the core material 20
Synthetic resin foams are mainly used, such as resins for polyurethane foam, resins for phenol foam, and resins for polyisocyanurate foam, and flame retardants and flame retardant aids (borax, sodium metaborate, antimony trioxide, Calcium carbonate, aluminum hydroxide), bentonite, pearlite grains, and shirasu balloons. 21 is a backing material that covers at least the backside of the core material 20 to make the board A a sandwich structure, which improves the mechanical strength of the board A itself, as well as packing a noncombustible sheet, a waterproof membrane, a heat shielding sheet, a water absorption sheet, and a soundproof sheet. For example, asbestos paper, kraft paper, asphalt felt, metal foil (Al,
Fe, Pb, Cu), synthetic resin sheets, rubber sheets,
It is made of a laminate of one or more of cloth sheets, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., or a sheet that has been treated with waterproofing or flame retardant treatment.

[Construction example]

[Effect of idea]

As described above, according to the siding board according to the present invention, at least one decorative rib is formed on the decorative surface portion, so that the strength is sufficiently reinforced to prevent warping, twisting, and unevenness, and the decorative surface has a mountain-like shape. I never get used to it. 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.
By providing a depression in the decorative groove, the division between the top and bottom surfaces of the decorative groove is clearly defined, the siding board closely resembles the contact area between the surface materials of the joint, and the shapes of the decorative groove and the joint are approximately the same. The scalene trapezoid shape creates uniform horizontal lines on the wall, giving it a three-dimensional feel and improving its aesthetics. Since the siding board has a sanderch structure, sound insulation, heat insulation, vibration insulation, fire resistance, condensation resistance, and mechanical strength are greatly improved. Because the siding board can be made wider,
It is easy to construct and is economical because the width of the material can be used effectively. A groove is formed on the insertion edge, which prevents capillary action at the connecting part and improves waterproofness. It has the following characteristics and effects.
