BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to its preferred embodiments.

The main component of the mounting structure of the inorganic decorative board of the present invention is an inorganic decorative board such as a gypsum board. In this embodiment, the inorganic decorative board is a moisture absorbing / releasing inorganic decorative board. This veneer is also called a moisture absorptive and fire retardant building material, and it is a moisture absorptive and desorptive material such as diatomaceous earth, zeolite, sepiolite and zonotolite, hydraulic substances such as cement, slag and gypsum, and organic reinforcing fibers such as pulp and rock wool. After forming, for example, a satin embossed pattern on the surface of the substrate made of either one or both of the inorganic fibers,
The surface is sputter coated.

The sputtering coating is applied to the surface of the base material under the condition that 20% to 80% of the surface of the base material is exposed. For coatings where the degree of exposure of the substrate surface is less than 20%,
Moisture-absorbing and desorbing properties of the substrate are impaired. On the other hand, under the sputtering coating condition that the exposure degree exceeds 80%, it becomes difficult to improve the design of the inorganic decorative board by coating.

Next, as the coating material used for applying the sputtering coating to the surface of the base material, in this embodiment,
It uses a paint that contains granular powder of moisture absorbing and releasing materials such as diatomaceous earth and zeolite. The particle size of the moisture absorptive and desorptive material powder is 5
It is in the range of μm to 500 μm. If the particle size is less than 5 μm, the surface of the coating film layer formed on at least one surface of the moisture absorptive and desorptive inorganic decorative plate cannot be a rough surface having a deep and excellent design. On the other hand, when the particle size is larger than 500 μm, the moisture absorbing / releasing material granular powder easily peels off.

The moisture absorbing / releasing material granules having a particle size of 5 μm to 500 μm are added in an amount of 2% to 40% by weight with respect to the presence of the paint. When the addition amount is less than 2%, at least one surface of the moisture absorptive and desorptive inorganic decorative board cannot be made a rough surface having a depth and excellent designability, and there is little contribution to the increase of the surface area due to the rough surface. On the other hand, if it is added in excess of 40%, the binding effect of the acrylic resin or the like becomes insufficient, and the moisture absorbing / releasing material granules are likely to peel off.

As the paint, a general-purpose polyester resin system is used.
Paint, vinyl resin paint, acrylic resin paint, ureta
Resin-based paint, silicone resin-based paint, fluororesin-based paint,

Nau.

As the additive, a surfactant, an emulsifier, an antifoaming agent, a pH adjusting agent, a fusing solvent, an antiseptic / antifungal agent, a chelating agent and the like are used alone or in combination.

In this embodiment, the moisture absorptive and desorptive inorganic decorative board has a thickness of 8 mm or more, for example, 1 mm or less.
It is 2.5 mm. With such a thickness, the impact strength becomes sufficient, the groundwork construction with gypsum board or the like can be omitted, and the nailing can be directly fixed to the fixing member such as the furring strip. Furthermore, by forming the textured portion as shown in FIG. 1, it is possible to secure a uniform joint width at the joints between the moisture absorptive and desorptive inorganic decorative boards, and to form a solid wall surface, ceiling, etc. can do. That is,
In FIG. 1, when forming the textured processed portion 2 on the inorganic decorative board 1, the inorganic decorative board 1 is made to have a lower protruding length a larger than an upper protruding length b. When abutted, the joint width g is g = a−b, and the greater the thickness t of the inorganic decorative board 1, the greater the depth of the joint portion, which can give a solid feeling.

Next, the component system of the base material of the inorganic decorative board in this embodiment will be described. The base material of the inorganic decorative board in the mounting structure for the inorganic decorative board of the present invention is basically 5% to 60% by weight with a particle size of 100 μm or less.
% A moisture absorbing / releasing material to be blended and a hydraulic substance. Water is added to the mixture of these raw materials and kneaded to form a slurry,
This is made into a paper to obtain a base material. As the paper-making method, a paper-making method using a knitting type paper making machine known per se can be used.

As the moisture absorbing / releasing material, diatomaceous earth, silica gel, zeolite, xonotlite, sepiolite, apatargite, tobermorite, allophane, white sand (shirasu), kaolinite clay, aluminum oxide, charcoal,
And one or more selected from activated carbon can be used. All of these are porous and excellent in moisture absorption and desorption.

In the base material of the inorganic decorative board in the mounting structure of the inorganic decorative board of the present invention, the moisture absorptive and desorptive material is compounded in the compounding raw material within the range of 5% to 60% by weight. If the blending amount is less than 5%, the moisture absorbing / releasing property cannot be imparted to the moisture absorbing / releasing inorganic decorative board. On the other hand, a blending amount of more than 60% reduces the bending strength and hardness, which are the primary physical properties of the moisture absorptive and desorptive inorganic decorative board. In this embodiment, in order to secure the primary physical properties of the moisture absorptive and desorptive inorganic decorative board, slag, cement, and other hydraulic materials,
The primary physical properties are complemented by blending either or both of the organic reinforcing fiber and the inorganic fiber.

In the base material of the inorganic decorative board in the mounting structure of the inorganic decorative board of the present invention, the moisture absorbing / releasing material has a particle size of 100 μm or less. When the particle size exceeds 100 μm, when the raw material slurry is wound up by a papermaking machine,
Moisture absorbent materials such as diatomaceous earth cannot separate to form a uniform mat. Usually, it is carried out with a particle size ≦ 70 μm. When the moisture absorptive and desorptive material is diatomaceous earth, the particle size range is preferably 10 μm to 100 μm.

By blending the hydraulic material, the matrix firmly adheres to the matrix to increase the strength of the base material of the moisture-absorbing / desorbing inorganic decorative board, and at the same time, the characteristics such as curing and molding can be imparted easily and inexpensively. Facilitates the production of a moisture-releasing inorganic decorative board. Further, the hydraulic substance has fireproof property, fireproof property, and also waterproof property. As the hydraulic material, slag, cement, gypsum, calcium carbonate, calcium silicate or the like can be used.

In the base material of the moisture-absorbing / releasing inorganic decorative board in the mounting structure of the inorganic decorative board of the present invention, the hydraulic substance is compounded in the compounding raw material within the range of 10% to 60%. If the blending amount is less than 10%, strength-imparting ability and waterproofness,
Hard to develop curing and molding characteristics. On the other hand, if the content exceeds 60%, the moisture absorptive and desorptive inorganic decorative board may increase in weight and may be cracked due to drying and shrinkage.

In the base material of the moisture absorptive and desorptive inorganic decorative board in the mounting structure of the inorganic decorative board of the present invention, the filling substance can be added to the raw material mixture as an extender.
As the filling substance, gypsum dihydrate: 2% to 30%, calcium carbonate: 0% to 20%, pearlite: 0% to 15%, slaked lime: 0% to 1.5%, mica: 0% to 8% It can be used within the range.

Organic reinforcing fibers such as pulp are added for the purpose of improving the strength of the moisture absorptive and desorptive inorganic decorative board and for improving the paper-making property. In the present embodiment, it is added within the range of 3% to 5%. If the addition amount is less than 3%, the effect of improving the strength and paper formability of the moisture absorptive and desorptive inorganic decorative board cannot be exhibited. On the other hand, if added in excess of 5%, the moisture-absorbing and releasing inorganic decorative board loses its properties as a non-combustible material because the pulp and the like of the moisture-absorbing and releasing inorganic decorative board are organic materials.

Inorganic fibers such as rock wool are added to improve the strength and processability of the moisture absorptive / inorganic decorative board, like the organic reinforcing fibers. In the present embodiment, it is added within the range of 1% to 8%. If the amount of addition is less than 1%, there is little effect on the strength and processability of the moisture-absorbing and releasing inorganic decorative board.
If it is added in excess of 8%, the workability at the time of adding water to the blended raw material and kneading will be impaired. Furthermore, fiber aggregates called lumps are mixed and impair the uniformity of the material of the moisture absorptive and desorptive inorganic decorative board.

The substrate of the moisture absorptive and desorptive inorganic decorative sheet thus obtained is subjected to sputtering coating with or without embossing to obtain a moisture absorptive and inorganic decorative sheet. Then, the moisture absorptive and desorptive inorganic decorative board is fixed to the wood-based fixing material such as a furring strip or a wild edge by using a finish nail. In this embodiment, for example, after applying an adhesive to the furring strip, a moisture absorptive and desorptive inorganic decorative plate is attached,
A finish nail is driven in from the surface of the moisture-absorbing / desorbing inorganic decorative plate and fixed.

The finish nail used for fixing the moisture absorptive and desorptive inorganic decorative plate is made of a stainless steel such as SUS304 having a flat rectangular head and a rectangular trunk cross section as shown in FIG. Nails can be used. As a dimension of the finish nail 3, for example, the short side w of the nail head plane shown in FIG. 2 is w = 1.3.
mm, nail head plane long side l = 1.4 mm, finish nail length L = 35 mm, nail body short side c = w, d = 1.3 m
m.

The finish nail 3 is driven so that its head is depressed more than the outermost surface of the inorganic decorative board. In the mounting structure of the inorganic decorative board of the present invention, the moisture absorbing / releasing inorganic decorative board has a matte surface, and further, for example, a sandstone-like embossed pattern is formed and the surface of the moisture absorbing / releasing material granular powder. The coating material added with is sputter-coated so that the surface of the base material is exposed by 20% to 80%. Inconspicuous and does not impair the design of the inorganic decorative board.

In the present invention, the nail head recess, which is driven so as to be depressed more than the outermost surface of the inorganic decorative board, can be filled with putty having the same color tone as the surface of the inorganic decorative board. . By doing so, the nail head recess can be made less noticeable.
