Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall material having a humidity control function and a heat island reducing technique using the outer wall material.

[0002]

2. Description of the Related Art In a building such as a house, a material having a humidity control function is used for a wall material in order to maintain a good humidity environment in an indoor space. In general, wooden building materials and fibrous building materials have a humidity control function, but are inferior in fire resistance, corrosion resistance, insect resistance and the like. Therefore, it has been proposed to construct a wall structure having an excellent humidity control function by blending a material having high moisture absorption and release properties such as diatomaceous earth with a building material having excellent fire resistance and corrosion resistance such as gypsum board.

Further, there has been proposed a technique for producing a ceramic tile having a humidity control function by blending the above-described material having excellent moisture absorption and release properties with a ceramic material as a raw material of the tile and firing the mixture.

A wall structure mainly composed of gypsum board can be used indoors, but cannot be used in an outdoor environment. In addition, since ceramic tiles are also manufactured using a special material, their physical property values such as impact resistance are inferior to ordinary outer wall materials, and there are many problems in using them outdoors.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to propose an outer wall material that can withstand outdoor use and has a humidity control function.

[0006]

According to the present invention, there are provided an outer wall material having a humidity control function in which (1) a humidity control material is housed in a perforated container having an outer wall material shape, and (2) a humidity control material. An outer wall material having a humidity control function in which a molded product is covered with a perforated cover and having an outer wall shape, and (3) an outer wall material having a humidity control function in which a humidity control material is applied on a base having an outer wall material shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. As shown in the figure, the present invention provides a humidity control material in a perforated metal or ceramic container formed into an outer wall shape such as a brick shape or a tile shape, or the formed humidity control material in a metal sheet. The outer wall material is an outer wall material that is covered with the like and has an outer wall shape, or an outer wall material formed by applying a humidity control material or pasting a humidity control material molded product on a substrate.

[0008] The humidity control material is basically used as a fired humidity control tile by adding a clay-like material as a binder to a material having a humidity control function, press-molding the resultant, and then firing. Alternatively, using a material having a humidity control function and a room temperature curable gypsum, a binder such as cement, press molding,
It may be used as a non-sintering humidity control tile obtained by molding by casting or the like and curing. Alternatively, it may be used in the form of granules or pellets without taking the shape of the fired and non-fired humidity control tiles.

As the material having the humidity control function, those used for ordinary building materials can be used. For example, various charcoal or zeolite, porous minerals containing sepiolite,
Examples include atavalgite, montmorillonite, zonotolite, clay minerals containing activated clay, and diatomaceous earth.
These materials can be used alone or in combination of two or more. These have the ability to physically or chemically absorb and release moisture in the air, and usually have many fine pores. The present invention is intended for use outdoors, and utilizes the ability to chemically and physically absorb and release moisture as well as the ability to contain water itself in the pores by capillary action.

[0010] Among the materials having the humidity control function, charcoal is
When used as a fired humidity control tile, firing in a reducing atmosphere is effective to prevent burning out in the firing step.

FIG. 1 shows an example in which the above-mentioned humidity control material is molded, housed in a stainless steel container having an outer wall shape, and used as an outer wall material. FIG. 2 shows an example in which the formed humidity control material is used by being covered with a metallic or ceramic cover formed into an outer wall material shape. It is also possible to attach the humidity control material directly to the outer wall and cover it from above. FIG. 3 shows an example in which the formed humidity control material is used by being covered with a metal sheet in an outer wall material shape. FIG. 4 shows an example in which a humidity control material is mixed with gypsum, cement, or the like and applied to a base.
In addition, the application includes sticking a humidity control material formed with an adhesive or the like on a base.

A hole is appropriately formed in the surface of the container or the covering material so that the humidity control material inside can be in contact with the outside air. The portion of the container or the cover where the humidity control material is exposed to rainwater or the outside air may be a mesh-like hole or a slit-like portion. In short, it is sufficient that the area be sufficiently exposed to rainwater and that it is sufficient to protect the internal humidity control tile. In the case of a fired humidity control tile or an unfired humidity control tile formed in the shape of an outer wall, a shape that protects the apexes and ridges is preferable.

When the humidity control material is formed into granules or pellets and filled or covered with the above-mentioned container, any shape may be used as long as the humidity control material does not scatter outside.

If the material of the container or the covering material is metal, stainless steel, aluminum,
It is made of a thin plate such as copper. In addition, enameled products and pottery products can be used as needed.

If the outer wall material configured as described above is used for an outer wall of a building, the humidity control material absorbs and adsorbs moisture in summer, during rain, or when the humidity in the air is high. Further, rainwater can be directly contained in the pores of the humidity control material by capillary action. Moisture releases naturally when the temperature rises or the humidity falls. At that time, heat of vaporization is deprived, and the temperature of the wall surface is lowered. This helps to reduce the energy required for building cooling and also reduces the heat island phenomenon.

Further, the outer wall material of the present invention can be applied to a soundproof wall. In addition to the humidity control function, a large amount of pores are included, so that a soundproofing effect can be expected.

When the humidity control material is used in the form of granules or pellets, vegetation seeds can be mixed and used. That is, greening of the wall surface can be achieved.

According to the present invention, since a humidity control material capable of containing moisture / water is formed into an outer wall and used, moisture absorbed during rainwater can be vaporized at a high temperature in summer. It has the effect of lowering the outer wall temperature. At the same time as reducing the cooling energy of buildings using this exterior wall material,
Mitigates the heat island phenomenon. In addition, by covering the humidity control material with a metal container or a metal sheet, the weak point of the ceramic using the humidity control material having a problem in strength can be usually solved.
