[Problems to be Solved by the Invention] For a building which is considered to be compatible with the climate of Japan, a wooden frame method is used to construct a living room composed of an earth wall, a tiled roof, an edge, a shoji, a shutter, etc. , A configuration of arranging a garden with plants,
Knit a bamboo lattice between the pillars on the wall, wrap a straw rope around it,
We mixed straw with mountain soil and solidified it, and finished it with a top coat, but it took labor and the construction period was long,
Due to the shrinking of the supply of residential land, which has been gradually shunned, the construction method of finishing narrow living spaces in an airtight structure has become the mainstream, but with this construction method, new construction materials,
Since synthetic resins or solvent-based paints are frequently used, phenomena causing malfunctions to the human body as described above have become remarkable.

[0005] As described above, current buildings tend to emphasize economics rather than livability as described above, and the housing area per house is narrow, the building coverage rate is high, the space is small, and the sound insulation is low. Due to necessity, the area of doors and windows is small and small, the distance between adjacent land is narrow, traffic,
In order to protect the living environment from harmful gases emitted from the energy industry, all of these dwellings have to be highly airtight and highly insulated, and regardless of the ground condition, they are solid foundations and concrete-like pool-like structures. As a structure that shuts off from the outside air, moisture intrusion into the underfloor part is reduced, but at the same time, air flow is also reduced, and there is almost no exposed wood surface that regulates humidity, causing dew condensation phenomenon, It has been pointed out that indoors are exposed to high temperature and high humidity, and harmful volatile components are generated by new building materials, synthetic resin-based interior materials, solvent-based paints, etc., causing bronchial or skin diseases. .

[0006] As a method for preserving the skeleton of the current building and preventing the above-mentioned diseases, at least the air inside the house is improved, and the harmful volatile substances generated are absorbed and removed. It has become an urgent task to promote the flow of air and to finish the interior using natural materials as much as possible in place of building materials or interior materials that generate harmful volatile substances.

[0007]

Means for Solving the Problems In order to provide a wall with air permeability and a function of adsorbing and removing harmful volatile substances, an activated carbon is filled between the walls, and both sides thereof are made of bamboo or other natural materials. Use a conventional method of making a frame, covering wallpaper that does not contain organic volatile substances, applying metal lath and applying wall soil, or constructing a wall with a material that does not emit organic volatile substances different from the conventional method This also prevents dew condensation on the wall surface and, even if the material itself is not generated, adsorbs organic volatile substances that may be contained in indoor air and lowers its concentration, thereby reducing the healthy environment. Can be realized.

BEST MODE FOR CARRYING OUT THE INVENTION The scallop shell was baked at 1050 ° C. and mixed with diatomaceous earth mixed with pulverized coal containing an appropriate amount of white charcoal obtained by calcination of a plant material at 1000 ° C. or higher while changing the composition of the conventional wall soil. A wall made of natural materials such as hemp, straw, woody cellulose, wool, etc., and natural seaweed or starch or other glue. The material kneaded with water is undercoated on the board, cured for about one day and dried, excluding the charcoal in the composition used as the undercoat as an overcoat,
A diatomaceous earth equivalent to the weight of the diatomaceous earth is further applied as a wall material to finish the wall. In this case, the wall can be finished in color by adding a pigment made of a natural material as a coloring material as needed. When the above-mentioned wall material is used for a long time, the capacity of the adsorbent contained therein is reduced, but a large amount of fresh air is forcibly blown at an appropriate cycle to activate the adsorbent. This enables long-term use.

As the undercoat material, a material obtained by removing the inner diatomaceous earth of the above components, that is, a material having bamboo charcoal as a main component,
A diatomaceous earth-based material may be applied thereon, and after drying, a three-layer finish may be used in which a diatomaceous earth-based material having a higher diatomaceous earth content than that described above is used as an overcoating material.

[0010] In order to suppress the growth of fungi derived from a highly airtight and highly heat-insulating structure, an extract of ash such as vegetation or bamboo or a boron compound may be added to the wall material.
