Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a siding board that is light and has high moisture permeability.

[Conventional technology]

As a siding board used for construction (hereinafter abbreviated as a board), a metal board is formed by using urethane foam or the like as a core material. In recent years, a board having a moisture control function provided with a sheet having a water-absorbent material attached in a dot shape on the back surface of the board has come to be used. (For example, Kokoku Sho 63
No. 29762) [Problems to be solved by the invention] In the former hoard using urethane foam as a core material,
There is a problem that dew condensation occurs on the core material, and the dew condensation water corrodes the furring to which the hoard is attached and other components, and even in the case of a hygroscopic material such as a nitrogen board. ,
Since the moisture once absorbed by the core material is difficult to dry, there is a problem that the heat insulating property of the board is significantly lowered.

Further, in the latter board, it is difficult to provide the water-absorbing material on the sheet in a dot shape, and there is a problem that it becomes expensive, and there is a problem that the water-absorbing material is easily broken from the adhered portion.
Moreover, since the volume of the water-absorbent material increases when it absorbs water, there is a problem that the sheet is deformed even when arranged in a dot shape.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a siding board which is excellent in moisture absorption and moisture release, and is lightweight and has a heat insulating effect. is there.

[Means for solving the problem]

In order to achieve the above-mentioned object, the siding board of the present invention is provided with a male connecting part on the upper part of the core material and a female connecting part on the lower part, and the vertical grooves are juxtaposed at appropriate intervals on the indoor side. The ventilation hole is penetrated downward, and the moisture permeable sheet is attached to the inside of the room.

[Action]

The moisture permeable sheet attached to the indoor side of the core absorbs moisture from the indoor side and is released to the vertical groove provided on the outdoor side. Since the vertical groove communicates with the outside by the ventilation hole provided below,
The moisture released to the vertical groove is released to the outside.

〔Example〕

Hereinafter, the structure of the siding board according to the present invention will be described with reference to the drawings of the embodiment. A male connecting portion 3 is provided on an upper portion of the core material 2 and a female connecting portion 4 is provided on a lower portion thereof, so that the inside of the core material 2 faces the interior. Vertical grooves 5 opening in the vertical groove 5 are provided in parallel at appropriate intervals, a ventilation hole 15 is continuously opened downward in the vertical groove 5, and a moisture permeable sheet 6 is attached to the inner surface 2a of the core 2. It is a thing.

The core material 2 is made of a waterproof material, and the male connecting portion 3 is provided with a mounting wall 3b projecting upward on the indoor side of the eave wall 3a which descends and slopes outward, and on the outdoor side of the mounting wall 3b. A concave groove portion 3c is formed, and the female connecting portion 4 hangs a connecting hand 4b below an intermediate portion of a bottom surface 4a which is inclined downward toward the outside of the room, and the female connecting portion 4 is inserted into the concave groove portion 3c of the male connecting portion 3 by the female board of the upper board 1 '. Mold connection part connection hand 4b
Is to be inserted. The vertical groove 5 is from the top of the core 2 to the bottom
4a, bite from the hanging position of the female connecting part connecting hand 4b to the outside of the room, and the ventilation hole 15 communicating with the vertical groove 5 penetrates the outside of the connecting hand 4b, leaving a notch at the lower part on the indoor side of the vertical groove 5. Twelve,
The moisture permeable sheet 6 is attached to the upper part of the core material 2 and the remaining cut portion 12 in the formation portion of the vertical groove 5 to allow moisture to permeate from the indoor side to the outdoor side, but does not permeate to the indoor side in the opposite direction. Things are desirable. As the material of the sheet 6, for example, an organic polymer exhibiting an ion exchange property, a cation exchange resin in which an ion exchange group is covalently introduced into a resin having a three-dimensional network structure, an anion exchange resin, or an amphoteric resin is preferable.

In the figure, S is a sealing material to be fitted and inserted on the outside of the male connecting portion mounting wall 3b.

The siding board shown in Fig. 4 is a material with excellent heat insulation,
For example, an eaves wall 3a inclined downward toward the outside is provided on the upper part of the core material 2 formed of styrofoam, urethane foam, etc., a recess is provided at the lower part on the indoor side of the core material 2, and an opening is made from the inside of the core material 2 toward the interior. Vertical grooves 5 to be provided in parallel at appropriate intervals,
A moisture permeable sheet 6 is attached to the interior surface 2a, and the outside of the core material 2 excluding the interior surface 2a is covered with a synthetic resin exterior material 7. The exterior material 7 connects the male connecting portion 8 and the female connecting portion. 9 is formed.

The male connecting portion 8 of the exterior material 7 has a mounting piece 8b standing upright on the indoor end of the oblique piece 8a attached to the eaves wall 3a of the core material 2, and is located outside the mounting piece 8b and lower than the mounting piece 8b. A waterproof piece 8d is provided oppositely, a concave groove 8c that opens upward is provided between the mounting piece 8b and the waterproof piece 8d, and the female connecting portion 9 is a lower piece 9a attached to the concave portion from the bottom surface 4a of the core material 2. , A connecting piece that hangs downward from the inner end of the lower piece 9a
The lower piece 9a is formed with a vent hole 15 communicating with the vertical groove 5, and the female connecting portion connecting piece 9b of the upper board 1'is inserted into the concave groove 8c of the male connecting portion 8. is there.

Since the board of the present invention has the above-mentioned structure, when it is mounted, it is to be sequentially and continuously attached from the lower part of the building to the upper part. After fixing the upper part of the board 1 by nailing the mounting wall 3b of the male connecting part 3 with the connecting part 4 facing down, the female connecting part 4 of the upper board 1'approaches the male connecting part 3 from above. Then, the connecting hand 4b of the connecting portion 4 is inserted into the previously fixed male connecting portion concave groove portion 3c so that the male connecting portion 3 is sequentially attached while being nailed.

[Effect of device]

Since the siding board of the present invention is configured as described above, it has the following effects.

Even if the core material of the board is made of waterproof material, a vertical groove is formed in the core material that opens toward the interior.Ventilation holes penetrate below the vertical groove, and a moisture-permeable sheet is attached to the interior surface. Since it is provided, the indoor water vapor that has permeated the indoor wall also permeates this moisture permeable sheet, and is released to the outside from the vertical groove of the board. The moisture-permeable sheet allows moisture to permeate from the indoor side to the outdoor side, but it does not allow water to pass through, so it blocks the reverse flow of rain from the outside, blocking the indoor surface of the board and the furring strip of the base on which it is mounted. , The other components will not be corroded by moisture. Even if a moisture permeable sheet is attached to the inside of the board, the mounting wall of the male type connecting part is nailed and the female type connecting part of the upper board is fitted and locked to the male type connecting part. It can be easily attached by just nailing the attachment wall of the connecting part.
