[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.

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, with this type of board, the decorative surface may deform into a mountain shape, lack insulation due to the lack of a backing material, and condensation water and leaked rainwater may accumulate inside the board and corrode the base and the board itself. There was a drawback. Moreover, the water stored in the joints of the boards,
In severe cold weather, it becomes ice and expands in volume, deforming the connecting parts and causing the boards to separate.
Furthermore, when this type of board is connected to form a wall, the joints and joints are clearly visible, resulting in an unsightly appearance.

In order to eliminate such drawbacks, the present invention provides drainage parts at appropriate pitches in the locking part where the lower end edge of the decorative surface is formed into an L-shaped longitudinal section, and also provides water drainage sections at appropriate pitches along the longitudinal direction of the decorative surface. The vertical cross section is scalene trapezoidal, and at least one or more decorative groove is formed that has a shape almost the same as the vertical cross section of the joint when the wall is formed, so that the joint also forms one unified pattern of the wall. It has a smooth and beautiful appearance, and has an engaging part at the upper end for forming the above-mentioned joint from the slope part, the joint base part, and the rib-like protrusion, and has a decorative surface,
The concave area surrounded by the locking part, the inclined part, the joint base part, and the outer surface of the protrusion is integrated with the constituent materials using self-adhesive properties, and is also integrally filled with synthetic resin foam that also serves as the core material. The decorative surface will not be scratched, deformed, warped, or twisted, and the engagement force of the connecting part will be significantly strengthened to prevent separation, and it will also improve workability, waterproofness, corrosion resistance, heat insulation, fire prevention, cushioning performance, and productivity. To propose a board that has good vibration-proofing properties, suppresses the accumulation of water in a locking part of the board, and can constitute a wall body having beautiful joints rich in three-dimensional effect.

2, which mainly functions as a joint base, engages with the locking part 4 , reduces contact of the surface material 1 with the base, rim, etc., and serves as vibration proof and as described later. It is useful for storing synthetic resin foam, and also serves as a mold material with a vertical cross section that does not leak raw material. To explain further, the inclined part 10 improves the flow of rainwater, prevents rainwater from accumulating in the joint ground part 11, promotes the three-dimensional appearance when the joint is formed, and increases the working width. It is useful for In addition, the basement area 11
consists of a vertical surface or a substantially vertical surface, and serves as a waterproof base for the joint and a guide for the locking piece 6, and the protrusion 12 engages the locking piece 6 under a certain elasticity, and also serves as a rain cover, and reinforcement to prevent deformation of the surface material 1 and formation of a triangular bent portion 11a to prevent capillary action between the locking piece 6 and the protrusion 12, and the lower edge of the outer surface 12a. is made to protrude horizontally or approximately horizontally by Δh from the lower edge of the inner surface 12b, thereby reducing the contact area between the base and the engaging portion 9 , and serving as one side of the mold for storing the synthetic resin foam raw material to be described later. It is something. Later, the horizontal surface 12c that protrudes by Δh allows the use of a flat plate material such as a steel belt to convey the surface material 1 , and the rotation speed can be much higher than that of a mold such as a caterpillar, which greatly improves productivity. Moreover, it is possible to reduce costs. Note that the angle θ ₄ is set only on the surface where the tongue piece 7 contacts in order to strengthen the engagement force.
Preferably, it is inclined. The specific angle θ ₄ is selected depending on dimensions such as the height h ₁ of the base 5 and the width W of the surface material 1 . Reference numeral 13 denotes a fixed part which vertically extends the lower edge of the outer side 12c of the protrusion 12, and mainly fixes the surface material 1 in a position where rainwater does not leak, as shown in FIG. ,

Reference numeral 14 denotes a tongue piece formed at the tip of the fixed part 13 as necessary, and is mainly used to prevent danger during construction and to prevent deformation such as waving of the fixed part. 15 is a concave portion surrounded by the decorative surface 2, the decorative groove 3, the bottom side 5, and the back surface of the engaging portion 9 ; 16 is a synthetic resin foam that is integrated into the concave portion 15 using self-adhesive properties; It functions primarily as a heat insulator, core material, cushion material, reinforcing material, adhesive, soundproofing material, moisture proofing material, and rustproofing material. Its shape corresponds to the recess 15, and
A notch 17 is provided at the end near the locking portion 4 so that a gap of approximately triangular or rectangular shape (not shown) is formed between the bottom and the tongue piece. The raw materials for the synthetic resin foam 16 include resins for polyurethane foam, resins for polyisocyanurate foam, resins for phenol foam, and flame retardants and flame retardant aids (borax, sodium metaborate, calcium carbonate, water, etc.). Aluminum oxide, antimony trioxide, bentonite, pearlite grains,
It is made by adding one or more types of whitebait balloons. In order to form the synthetic resin foam 16, the raw material is discharged into the recess 15, placed, etc., reacted and foamed, and then integrated using the self-adhesive property at that time. Reference numeral 18 denotes a backing material made of a sheet-like material that covers the backside of the synthetic resin foam 16 to make the board a sanderch structure, improving the mechanical strength of the board itself, as well as a noncombustible sheet, a waterproof membrane, a heat shielding sheet, a water absorbing sheet, It is useful as a soundproof sheet, packing material, etc., such as asbestos paper, kraft paper, asphalt felt, metal foil (Al, Pb, Fe), synthetic resin sheet, rubber sheet, cloth sheet, glass cloth.
or a combination of one or more of these, or a sheet that has been treated with waterproofing or flame retardant treatment. In addition, synthetic resin foam 1

Next, a construction example will be explained.

Assume now that boards as shown in FIG. 1 are laid horizontally as shown in FIG. 9 to form an exterior wall.
Therefore, the first stage board ○I is fixed to the studs, wall base, or rim A using nails B. Then the second
The locking part 4 of the board ○B in the tier is engaged with the engaging part 9 of the board ○i in the first tier, and its fixing part 13 is fixed to the stud A in the same manner as above. Therefore, in order to construct the entire outer wall, the above steps can be performed sequentially from the base toward the girder.

What has been described above is only one embodiment of the board according to the present invention, and FIGS. 10 a to c, FIGS. 11 a and b,
Figures 12a-g, Figures 13a-f, and 14
It can also be formed as shown in Figures a to d.

That is, FIGS. 10a to 10c are boards in which two decorative grooves 3 are formed on the decorative surface 2, or the depth d is different from the above, and FIGS. 11a and b are boards in which two decorative grooves 3 are formed on the decorative surface 2.
12a-g show the deformation of the locking part 4 , and FIGS. 13a-f show the protrusion 1.
FIGS. 14 a to 14 d show modified examples of the shape of the cutout portion 17 of the synthetic resin foam 16. FIGS. Furthermore, although not shown, the decorative grooves 3 and the joints may be formed into trapezoidal or angular shapes.

As mentioned above, according to the board according to the present invention,
Capillarity does not occur in the continuous structure of the locking part and the engaging part, and rainwater does not leak inside the surface material due to the tongue of the locking part and the protrusion of the engaging part. It has the characteristic that it does not corrode the foundation or the inside of the wall. Additionally, the board is fixed in a location where rainwater does not infiltrate, which has the advantage of preventing rust from forming on the fixtures. Furthermore, since water drainage parts are formed at appropriate pitches in the locking part, even if condensation forms on the locking part, it does not accumulate in the locking part and flows to the outside, preventing rust on the surface material and preventing condensation. It has the feature that water does not turn into water and separate from the engagement part. In addition, since the decorative grooves are formed on the decorative surface, the long board does not deteriorate in appearance due to warping, twisting, or bending. Moreover, since the decorative groove has a scalene trapezoidal longitudinal section, the appearance is the same as the joint when the boards are connected, and the joint functions as a pattern like a conventional wall, making it possible to create a wall with a beautiful appearance. There is. In addition, the decorative grooves and joints have a scalene trapezoidal vertical cross section, which allows for better drainage and creates a three-dimensional effect rather than the actual dimensions. Furthermore, by creating a height difference of Δh between the joint base and the fixed part, and by matching the height relationship between the locking part and the engaging part, the area in which the base and the board come into direct contact is small, and Since there is a synthetic resin foam that also has cushioning properties, the transmission of vibration to the board is small, and the connection part has the advantage of being difficult to separate. In addition, since the recess is integrally filled with synthetic resin foam and the back side is covered with a sheet-like material, when a board wall with a sanderch structure is formed, it has excellent soundproofing, heat insulating, and vibration proofing properties. It is characterized by significantly improved fire resistance, condensation resistance, and mechanical strength. In addition, since the concave portion 14 is formed to have a cross section that can be used as a mold material, it can be conveyed by a steel belt or the like, which greatly improves productivity.
