Description

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

[Conventional technology]

As a siding board used for construction (hereinafter, abbreviated as a board), a board having glass wool as a core material is often used. In recent years, a board having a humidity control function, in which a back sheet of the board is used as a waterproof layer and a water-absorbing material is attached to the sheet in dots, has been used. (For example, Kokoku Sho 63
-29762) [Problems to be solved by the invention] In the former board using glass wool as a core material, water such as dew condensation water is absorbed or absorbed during long-term use, and a part of the water drops. Then, there is a problem that the furring strip and other components are corroded, and once it absorbs moisture, it does not dry and the heat insulating property is greatly deteriorated.

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,
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 if the water-absorbent material is arranged in dots.

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 Problems]

In order to achieve the above-mentioned object, the siding board according to the present invention is a plate body in which a heat insulating material is covered with at least a hygroscopic and moisture-permeable protective material, and vertical grooves open to the outside are formed in parallel. A female connecting portion is provided in the lower part of the plate, a metal exterior material is attached to the outside of the plate body, a male connecting portion is provided in the upper part of the exterior material, and a draining piece is hung in the lower portion.

In addition, for the same purpose, a plate body in which vertical ridges are projected in parallel at the center of the outdoor side of the heat insulating material, and a protective material is provided outside the lower inner surface of the heat insulating material and the outer surface of the vertical ridge, and its chamber. It is composed of a metal exterior material that is attached to the outside, a male connecting part is provided on the upper part of the exterior material, a draining piece is provided on the lower part, and a waterproof wall protruding upward from the eaves wall is provided on the male connecting part and The mounting wall may project upward from the inside.

[Action]

Heat conduction is prevented by the heat insulating material that constitutes the plate body, and dew condensation water and moisture in the air are absorbed by the protective material. The moisture absorbed by the protective material is released by the temperature rise and the wind passing along the protective material, and the vertical grooves further promote the release of moisture.

In the plate body provided with the protective material on the outside of the lower portion of the inner surface of the heat insulating material and the outer surface of the vertical protrusion, it is easier to absorb and release moisture.

[Effect of device]

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

Since the heat insulating material of the board has heat insulating properties, heat conduction is prevented by the heat insulating material. Further, since the protective material covering the heat insulating material has hygroscopicity and moisture permeability, even if dew condensation occurs on the board or the building, the dew condensation water is absorbed and the moisture in the air is also absorbed. Moreover, the moisture once absorbed by the protective material evaporates due to the rise in temperature and the wind blown on the protective material and is released to the outside of the room, so that the moisture absorbing effect is permanent.

Also, in the proposed board, the mounting wall of the male connecting portion is nailed, and the female connecting portion of the upper board is fitted and locked to the male connecting portion,
Since the boards are mounted one after another, not only is the board easy to install, the drainer provided at the bottom of the exterior material hangs down to the male joint of the lower board, and the drainer and male joint are connected. Since the outside air portion that communicates with the outside is formed between the portions, rainwater that drops along the exterior material is blown along the back surface of the draining piece or into the outside air portion. As a result, rainwater is not sprayed directly onto the board connections. Further, in a board that penetrates through a hole in the heat insulating material and has a moisture-permeable portion integrated with the protective material in the hole, or a board provided with a protective material outside the lower inner surface of the heat insulating material and the outer surface of the vertical ridge, The moisture absorbed by the protective material can be released more easily.
