The floor board 3 is made of a paulownia veneer-adhered humidity control board 10, and the shelf board 5 and the pillow shelf board 6 are made of a paulownia veneer board-attached board material 15. FIG. 3 schematically shows the components of the indentation.

  The paulownia veneer paste humidity control board 10 used for the ceiling board 1, the wall board 2 and the floor board 3 is basically the same structure as each other, with the wall board 2 shown in FIG. 4 and the ceiling board 1 shown in FIG. As illustrated respectively (the floor board 3 is not shown in the figure, but has a similar structure), the paulownia veneer 12 having a thickness of 0.1 to 1.0 mm is provided on the surface of the humidity control substrate 11 (the surface facing the indentation space). It is a thing stuck together.

  In addition, as shown in FIG. 4, the one side part of the width direction of the wall board 2 has the female real part 2a which notched the front side to the rectangular shape, and the back side was made rectangular in the other side part. The notched male part 2b is formed, and at the time of construction, a pair of adjacent wall plates 2 and 2 are abutted, and the male part of the other wall plate 2 is in contact with the female real part 2a of the one wall plate 2 By engaging the portion 2b, the wall plates 2 and 2 are actually connected to each other. In addition, as shown in FIG. 6, on one side portion in the width direction of the ceiling plate 1, there is a female real portion 1 a composed of a rectangular groove cut out in the middle portion in the thickness direction, and on the other side portion, A male part 1b is formed by cutting the front and back sides into a rectangular shape, and at the time of construction, a pair of adjacent ceiling plates 1 and 1 are brought into contact with each other. By fitting the male part 1b of the ceiling plate 1, the ceiling plates 1 and 1 are actually coupled to each other (see FIG. 7).

  The humidity control substrate 11 is made of a wood fiber board or an inorganic board. As the wood fiber board, for example, a fiber board such as a class A insulation board is used.

  Moreover, as shown in FIG. 4 or FIG. 6, the said inorganic board has the core layer 11c which consists of an inorganic foam and a binder between the front and back layers 11a and 11b which consist of mineral fiber, an inorganic powder, and a binder. A three-layer structure in which laminated layers are integrated and a hygroscopic material is added to at least one of the front and back layers 11a, 11b or the core layer 11c, or a mineral fiber, an inorganic powder, a binder and an absorbent, although not shown. A two-layer structure (may be three or more layers) made of a moisture-releasing material is used.

  The front and back layers 11a and 11b of the former inorganic board are the same as each other, and are formed of a wet mat obtained by wet-making a slurry containing mineral fiber, inorganic powder and binder as essential components. On the other hand, the core layer 11c is formed of a mixture containing an inorganic foam and a binder as essential components.

  For example, rock wool, mineral wool, glass wool or the like is used as the mineral fiber in the front and back layers 11a and 11b. The composition ratio of the mineral fiber is 20 to 60% by weight in each of the front and back layers 11a and 11b.

  As the inorganic powder, for example, calcium carbonate, aluminum hydroxide, microsilica, slag and the like are used. The composition ratio of the inorganic powder is about 30 to 70% by weight in the front and back layers 11a and 11b. This inorganic powder improves the fire resistance and hardness of the humidity control substrate 11 and also improves the mounting and fixing properties. The inorganic powder also functions as a bulking agent.

  Further, as the binder, for example, melamine resin, phenol resin, poval, epoxy resin, starch or the like is used. The composition ratio of this binder is about 7 to 15% by weight.

  In addition, as auxiliary additives in the front and back layers 11a and 11b, for example, synthetic fibers such as polypropylene, polyester and vinylon, plant fibers such as hemp and flax, and woody fibers are added. Moreover, you may add an aggregating agent, a size agent, an antifoamer, an admixture, etc. as needed.

  On the other hand, as the inorganic foam in the core layer 11c, for example, pearlite, shirasu foam, silica flour, glass foam or the like is used. The composition ratio of the inorganic foam is about 40 to 90% by weight in the core layer 11c.

  As the binder, for example, melamine resin, phenol resin, poval, epoxy resin, starch or the like is used. The composition ratio of this binder is about 7 to 15% by weight in the core layer 11c.

  In addition, the core layer 11c includes, for example, mineral fibers such as rock wool, mineral wool, and glass wool, synthetic fibers such as polypropylene, polyester, and vinylon, plant fibers such as hemp and flax, and wood fibers such as 1 About 40% by weight may be added. In addition, an inorganic powder such as calcium carbonate may be added.

An example of the moisture absorbing / releasing material added to at least one of the core layer 11c and the front and back layers 11a and 11b is B-type silica gel. The B-type silica gel is powdery, and its particle diameter affects the surface properties of the humidity-controlling substrate 11, so that it is preferably 20 mesh or more (passes through a 20-mesh sieve). The composition ratio of the B type silica gel is about 5 to 40% by weight. By adding this moisture absorbing / releasing material, the humidity control substrate 11 has moisture absorbing / releasing performance. The moisture absorption / release performance is, for example, preferably 50 g / m ² · 24 h or more, and more preferably 70 g / m ² · 24 h or more (both JIS A1470-1 “Hygroscopic moisture absorption / release properties of building materials) "Test method (medium humidity)"). In addition to the B-type silica gel, for example, bentonite, sepiolite, zeolite, diatomaceous earth and the like, mineral-based and clay-based materials having moisture absorption / release performance can be used as the moisture absorption / release material.

  Although the latter inorganic board is not shown, the wet inorganic board is formed by laminating and integrating two wet mats obtained by wet papermaking of the slurry to form a two-layer structure having front and back layers. As with the former, the wet mat has mineral fibers, inorganic powder and binder as essential components, and also has a moisture absorbing / releasing material (B-type silica gel) as essential components. Other material components are the same as those of the former inorganic plate.

  On the other hand, the paulownia veneer-pasted board material 15 used for the shelf board 5 and the pillow shelf board 6 is basically of the same structure, and the shelf board 5 is shown in FIGS. 8 and 9, and the pillow shelf board 6 is shown in FIG. As shown in FIG. 1, paulownia projecting plates 17 and 17 having a thickness of 0.1 to 1.0 mm are integrally attached to the front and back surfaces of the wooden material 16. As the wood material 16, for example, paulownia wood timber is preferable, and other wood material wood timber or plywood may be used as long as it has strength.

  In FIGS. 8 and 9, 7 is a saddle member made of a single paulownia plate fixed to the lower part of the front end of the shelf board 5 and the pillow shelf board 6, and 8 is a saddle reinforcement material fixed to the flange member 7 with wood screws ( (Not shown in FIG. 3), 9 is an intermediate reinforcing bar (reinforcement joist) fixed to the lower surfaces of the shelf board 5 and the pillow shelf board 6 with wood screws.

  The method for constructing the above indentation is the same as the ordinary indentation construction method. That is, the construction method will be schematically described. For example, when constructing a wall, as shown in FIG. 5, in the wall foundation structure in which the trunk edges 22, 22,. .. Are fixed with adhesive (not shown) and nails 23 on the barrel edges 22. At the time of construction of the wall plate 2, a pair of adjacent wall plates 2, 2 are butted together, and the male part 2 b of the other wall plate 2 is fitted to the female part 2 a of one wall plate 2, The wall plates 2 and 2 are actually connected. The distance between the adhesive and the nail 23 with respect to the trunk edge 22 is preferably equal to or less than a predetermined (for example, 150 mm).

  On the other hand, when constructing the ceiling board 1, as shown in FIG. 7, a field edge 24 (see FIGS. 1 and 2) suspended by a hanging tree (not shown) and the field edge 24 are fixed. The ceiling boards 1, 1,... Are fixed to the ceiling foundation structure having the ceiling foundation material 25 such as plywood by staples 26 and nails 27. At the time of construction of the ceiling board 1, by fitting a pair of adjacent ceiling boards 1 and 1 and fitting the male part 1b of the other ceiling board 1 to the female part 1a of one ceiling board 1, The ceiling boards 1 and 1 are actually connected. In FIG. 7, 28 is a rounded edge. In addition, although the construction method of the floor board 3 is abbreviate | omitted, it is the same as that of the floor board 3 in normal insertion.

  Furthermore, the shelf board 5 and the pillow shelf board 6 are constructed with respect to the indentation in which the said wall board 2, the ceiling board 1, and the floor board 3 were constructed. The construction methods of the shelf board 5 and the pillow shelf board 6 are the same, and the case of the shelf board 5 (pillow shelf board 6) will be described. The rear joist 30 and the horizontal joists 31 and 31 are attached to the mounting height positions 22 respectively, and the shelf board 5 (pillow shelf board 6) is mounted on the rear joists 30 and the left and right horizontal joists 31 and 31 and fixed. In addition, the saddle material 7 of the shelf board 5 (pillow shelf board 6) is also fixed to the lateral joists 31, 31 at the left and right ends. Then, a rag 32 is attached to each upper surface of the rear end and the left and right ends of the shelf board 5 (pillow shelf board 6). Thus, the indentation is performed.

Therefore, in this embodiment, the paulownia veneer-adhered humidity-adjusting plate 10 having the paulownia veneer 12 attached to the surface of the humidity-adjustable substrate 11 is used for the ceiling plate 1, the wall plate 2 and the floor plate 3, and the paulownia Since the lumber-adhesive plate-adhered moisture-adjusting plate 10 is intended to compensate for the weakness of the paulownia material's moisture absorption / release performance while retaining the effects specific to the paulownia material (eg, insect repellent effect, low shrinkage rate, etc.), The ceiling surface, the left and right walls, the rear wall surface, and the floor surface are covered with the paulownia material, so that the features of the paulownia material are expressed, and an indentation with high humidity control performance is obtained. According to the inventor's experiment, the paulownia alone has a moisture absorption / release performance of, for example, 25 g / m ² · 24 h, whereas the paulownia used for the ceiling board 1, wall board 2 and floor board 3. The moisture absorption / release performance of the veneer-adhesive moisture-controlling plate 10 was, for example, 35 g / m ² · 24 h (all according to JIS A1470-1 “Hygroscopic building material moisture absorption / release test method (medium humidity range)”).

  Moreover, since the shelf board 5 and the pillow shelf board 6 are the paulownia veneer veneer board 15 which stuck the paulownia veneer boards 17 and 17 on the front and back of the wooden material 16, the board which consists only of weak paulownia materials is used. If it is possible to make the thickness thinner than that, and adopt a low-cost wooden material 16, it is only necessary to paste a paulownia material having functionality only on the front and back surfaces as a thin protruding plate 17, the shelf board 5 and the pillow shelf board 6, As a result, the cost of indentation can be reduced.

(Other embodiments)
In the above embodiment, as the shelf board 5 and the pillow shelf board 6, the paulownia veneer veneer plate 15 in which the paulownia veneer plates 17, 17 are pasted on the front and rear surfaces of the wood material 16 is used. A paulownia veneer-pasted plate material 15 in which a paulownia veneer veneer 17 is attached to one of the front and back surfaces may be used.

  Moreover, although the said embodiment applies this invention to intrusion, this invention is applicable also to the closet which is another storage space. In that case, with respect to the door plate that opens and closes the closet, similarly to the shelf plate 5 (pillow shelf plate 6), for example, the thickness is 0.1 to 1.0 mm only on the front and back surfaces of the wooden material or the back surface facing the inside of the closet. It is preferable to use a paulownia veneer-laminated plate material in which the paulownia veneer veneer is integrally attached.

  In this way, the same effect as in the first embodiment is obtained, and the use area of the paulownia material is further increased by the door plate having the paulownia wood veneer on the front or back surface or the back surface of the wood material, and the effect of the paulownia material is obtained. It can be further increased.

  INDUSTRIAL APPLICABILITY The present invention can compensate for the weak point of paulownia wood having a low moisture absorption / release performance with a humidity control plate material while maintaining an effect specific to paulownia wood, and is extremely useful and highly industrially applicable.
