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
-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 condensed water corrodes the furring to which the hoard is attached and other components, and even in the case of a material having a hygroscopic property such as a ceramic board. However, 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 object, a siding board according to the present invention is composed of at least a moisture-permeable core material and a waterproof exterior material that is attached to the outdoor side of the core material. On the other hand, the female connecting portion is formed on the lower part of the core material.

[Action]

Since the core material is rich in moisture permeability, dew condensation that occurs between the core material and the body is absorbed by the core material. The moisture absorbed by the core material is released to the outside air because part of the core material is in contact with the outside air.

〔Example〕

Hereinafter, the structure of the siding board according to the present invention will be described with reference to the drawings of the embodiment. In the hoard 1, an exterior material 3 is attached to an outer side of a core material 2, a male connecting portion 4 is provided on an upper portion, and a female type is provided on a lower portion. It has a connecting portion 5.

Among them, the upper surface of the core material 2 is formed into a slanted wall 2a inclined downward from the indoor side to the outdoor side, a female connecting portion 5 is formed in the lower portion of the core material 2, and the female connecting portion 5 has a bottom surface 5a. A concave groove 5b that opens downward is provided in the central portion, and is formed of a material having at least hygroscopicity and moisture permeability, such as diatomaceous earth or gypsum.

The exterior material 3 is attached to the outside of the core material 2 except for the interior surface 2b and the bottom surface 5a, the male connecting portion 4 is provided on the upper portion, and the water section 3a hanging downward from the core material 2 is provided on the lower portion, The male connecting portion 4 is the core material 2
Eaves wall 4a attached to the slanted wall 2a, a mounting wall 4b that rises from the indoor side of the eaves wall 4a, and a hook wall that is inserted into the groove 5b of the female connecting portion 5 that is folded back to the outside from the upper end of the mounting wall 4b. It is formed of 4c and is made of a steel plate, an aluminum plate, or a synthetic resin plate.

Since the hod of the present invention has the above-mentioned structure, when mounting it, the hod must be installed continuously from the bottom of the building to the top. Specifically, the exterior material 3 is directed to the outside, and the female connecting part 5 is lowered. Then, the mounting wall 4b of the male connecting portion 4 is nailed to fix the upper portion of the board 1, and then the upper board 1'is attached to the upper portion.
Is approached, and the female connecting portion concave groove 5b of the board 1'is fitted into the hook wall 4c of the male connecting portion 4 which is previously fixed, and the male connecting portion mounting wall 4b of the upper board 1'is fixed by nailing. It is a thing.

Since the core material 2 mainly composed of diatomaceous earth is rich in hygroscopicity and moisture permeability, dew condensation generated on the inner surface 2b of the board 1 or the outer side of the body of the board is absorbed by the core material 2 and the core material 2 The moisture absorbed by the water is released from the bottom surface 5a exposed to the outside air.

The exterior material 3 shown in FIG. 6 is obtained by making the inner surface of the exterior material 3 rough so that the core material 2 can be easily attached.

[Effect of device]

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

Since the core material of the board is formed from diatomaceous earth, which has hygroscopicity, moisture permeability, and moisture release, even if dew condensation occurs between the board and the building, the condensed water is absorbed by the core material, It doesn't collect between the building. Moreover, the moisture absorbed by the core material evaporates due to the rise in temperature,
Since the wind that blows onto the core material evaporates it and releases it to the outside air, the moisture absorption effect of the board is permanent. As a result, the rims and other construction materials on which the board is mounted are not corroded by moisture.
