Abstract

PROBLEM TO BE SOLVED: To improve the function by adding lime to a main material consisting of charcoal grain, cement and waste paper pulp followed by hardening and molding, and exposing the charcoal grains on the surface. SOLUTION: Lime or the like is added to a main material consisting of a mixture of charcoal grain or charcoal powder 1, cement 2, and waste paper pulp, and the mixture is hardened and molded by use of a mold to form a hardened molded product 3 such as inner wall material 3' or the like. The molded product 3 has charcoal grain or charcoal powder exposed to the outer surface to absorb the moisture in the wet air or release the moisture to the air in drying to regulate the air moisture. The molded product 3 having a triangular section is used as the corner material of a room for dwelling house to absorb dew in a corner angle part to regulate the air moisture. Further, an inner wall material 3' is horizontally fitted to a recessed part formed on the inside bottom part of a concrete foundation to form an underfloor moisture regulating material, whereby the moisture staying under the floor can be properly regulated, and harmful insects can be also exterminated. According to this, the interior or underfloor moisture can be automatically regulated, and heat insulating property and fire resistance can be also improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded building material mainly comprising a mixture of charcoal particles and cement.

[0002]

2. Description of the Related Art Conventionally, charcoal formed in a plate shape having a certain thickness, and the plate-shaped charcoal adhered to a plate material has been developed as an inner wall material having humidity control properties and heat insulation properties (Japanese Patent Laid-Open No. Hei 6-1994). 4991
No. 6).

[0003] However, charcoal is easy to burn, and even if it is attached to a plate, it is made of wood and has high heat insulation, but it is a flammable substance.
There was a problem of being unprotected against fire.

[0004]

SUMMARY OF THE INVENTION The present invention is a so-called moisture absorbing material which absorbs dew condensation and releases absorbed moisture into a room in a dry atmosphere. The purpose of the present invention is to obtain a rich building material for humidity control. Another object of the present invention is to provide a building material for under-floor humidity control that does not require a ventilation fan to reduce under-floor moisture and saves electricity bills, and does not require the use of a solar cell that does not generate power at night or on a cloudy day.

[0005]

In order to achieve the above object, the present invention comprises a mixture of charcoal particles, cement and waste paper pulp as a main material, adds lime or the like, hardens and forms, and exposes the charcoal particles to the outer surface. The charcoal-based building material according to the first aspect of the present invention, which is hardened to the corner material of the charcoal-based building material room according to the first aspect of the present invention, which is formed by hardening the inner wall material of the charcoal-based building material room according to the first aspect of the invention, wherein charcoal powder is used instead of the charcoal-based building material. The charcoal-based building material according to the first aspect of the present invention is constituted by the charcoal-based building material according to the first aspect of the present invention, which is hardened and formed into the underfloor humidity control material according to the first aspect.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Charcoal particles 20 of 2 to 4 mm
0 g, 500 g of cement, and waste paper pulp (about 3% by weight) are mixed to obtain an essential material (main material), mixed with water, and hardened and formed into an inner wall material 3 ′ by a mold. Charcoal powder can be used instead of the charcoal particles 1.

[0007] In addition to waste paper pulp, lime, slaked lime or quick lime, fly ash, calcium carbonate, shirasu balloon, carbon fiber and the like can be added.

Further, the above-mentioned cured molded article 3 can be used as a corner material 3 ″ (angle, triangular material) for a room in a house.

A rising portion is formed on the ground 6 on the outer periphery of the concrete slab 7 cast below the ground 6 to form a foundation 8
Then, a base 9 is placed on the base 8, and the base 9 and the base 8 are fixed with anchor bolts. On the upper surface of the concrete slab 7 surrounded by the foundation 8, a rectangular recess 7 'is formed in parallel with the inner periphery of the foundation 8, and the inner wall material 3' (thickness of about 50 to 100 mm) is horizontally placed in the recess 7 '. It fits and forms the underfloor humidity control material 3a.

The inner wall material 3 'is 220 mm × 2 in length × width.
20 mm, thickness 7.15 mm to 15 mm, weight 358.
In the range of 4 g to 616.7 g, the bending stress is JIS-A-1.
22.6 to 34.6 kg · f / cm ²
was gotten.

The charcoal particles or charcoal powder 1 are exposed on the outer surface of the cured product 3. Since the charcoal particles or powder 1 are hydrophilic and communicating and porous, they absorb moisture in the humid air into the interior, and when the air dries, perform so-called moisture respiration to release the absorbed moisture into the air. Can be adjusted.

On a rainy day or the like, the room air is filled with moisture, and when the temperature drops in that state, dew forms on the inner wall, and the structural material 4 and the like at the corners rot. When the humidity becomes high, molds and the like easily propagate in the corners. However, by using the above-mentioned angle, triangular material or the like for the corner material 3 ″ in the corner of the room, moisture and dew can be absorbed, and the moisture in the corner of the room can be absorbed. Can be adjusted.

The moisture stagnant under the floor is absorbed by the underfloor humidity control material 3a fitted into the concave portion 7 'of the concrete slab 7 under the floor, so that the underfloor humidity is appropriately adjusted. It can keep the moisture inside moderately and can cope with pest control.

In the figure, reference numeral 4 denotes an indoor structural material, 5 denotes a perforated decorative sheet, and 7 ″ denotes a moisture-proof layer.

[0015]

Since the present invention is constructed as described above, it can not only automatically adjust the humidity in the room or under the floor, but also has excellent heat insulating properties and excellent flame retardancy (tc... 8.26 or more). There is an effect that building materials with high fire safety can be easily obtained.
