The constant humidity storage according to the first embodiment of the present invention described above was tested for the amount of absorbed moisture and the amount of released moisture. The test was carried out at a constant humidity of 20 ° according to the first embodiment.
After being left in an environment of C and 55% RH, the equilibrium state was confirmed, and then the time change of the amount of moisture absorption when transferred to an environment of 20 ° C. and 80% RH was measured. Further, as a comparative example, a conventional storage was similarly tested. The result of the amount of moisture absorption is shown in FIG.
It shows in (a). (Taking the example of example 96 hours) moisture measurement results can be seen moisture absorption is extremely better than 202 g / m ² becomes, 58 g / m ² of a conventional storehouse. After confirming the equilibrium state by leaving it in an environment of 20 ° C. and 55% RH, the time change of the amount of moisture released when it was transferred to the environment of 20 ° C. and 35% RH was measured. As a comparative example, the same conventional storage was similarly tested. The result of the amount of moisture released is shown in FIG. As a result of the moisture release measurement (for example, taking 96 hours as an example), it is found that the moisture release amount is 135 g / m ² , which is much better than the conventional storage of 44 g / m ² . In addition, when the acid / alkali measurement was performed on the constant humidity storage according to the first embodiment, it was found to be in the neutral range. This is an optimum measurement value for a storage that stores art objects.

As described above, in the first embodiment, the material used for the surface material of the walls and ceiling of the storage is a natural material, especially a material that has a high moisture absorption and desorption performance and is soft and capable of absorbing shock. I use cedar. Japanese cedar has the unique softness and warmth as well as the ability to mitigate humidity fluctuations.
It is a safe material that does not contain artificial ingredients. In addition, horizontal and vertical ventilation grooves are formed in the surface material and the base material, which makes it easier for air to reach the base material side, increasing the function of the humidity control function and the air conditioning function, and the storage environment. Can be cleaned. The adhesive is also characterized by using urethane non-formalin. Acetic acid adhesives are harmful to works of art, but urethane adhesives have been found to be free of harmful components as in the past, which prevents them from deteriorating for more than 50 years.

In FIG. 22, the wall surface material 240 for wall is used as the piece plate 2.
It is a figure which shows the layout fixedly arrange | positioned on 36. For fixing the wall surface material 240 for walls, screws and urethane-based adhesives are used to adjoin the surface materials adjacent to each other in the vertical direction, and the wall surface materials 240 adjacent to each other in the horizontal direction are separated by a predetermined distance (for example, 5 mm). Place and fix. In this way, joints having a clearance of about 5 mm are formed in the vertical direction from the floor to the ceiling.

Further, the vertical gaps of the wall surface material 240 may be covered with a vertical joint plate 248 to improve the appearance. Therefore, the piece plate 236 of FIG.
The same piece plate 246 is used to fix the wall surface materials 240 at appropriate places above and below the joints, which are vertical gaps, with screws and urethane adhesive. A plurality of piece boards 2 between the upper and lower parts
The vertical joint plate 248 may be fixed with screws and a urethane adhesive so as to cover the bridge plate 246 between 46 and 246.
Even if the vertical joint plate 248 is fixed in this manner, since the vertical joint plate floats by a thickness of 5 mm of the piece plate 246, the air flow is not much different from that in the case without the vertical joint plate. The state in which the vertical joint plate 248 is provided is illustrated as 248 in the perspective view of FIG. Since the vertical joints are also spruce joints, it gives the calm feeling of natural wood.

An example of the flow of air in the constant humidity storage according to the second embodiment described above is as shown by the thick arrow in FIG. 22, for example. That is, assuming that the air intake port is provided below the wall portion and the air outlet port is on the ceiling portion in a diagonal relationship with the air intake port, the air intake port → the wall base material 230 and the wall surface material 240 A gap of 5 mm between them → a clearance (part) → enters the room, and from the room, as shown in FIG. 22, room → clearance (joint part) → wall base material 2
A path such as a 5 mm gap between the wall surface material 30 and the wall surface material 240 → an air outlet is formed, and eventually an air flow is generated on the back side of all the surface materials 140, so the humidity control effect is improved. Note that, in FIG. 22, in order to clearly show the flow of air, the respective ventilation grooves and the separation gaps are schematically drawn with being enlarged and emphasized more than they actually are.

With respect to the constant humidity storage according to the second embodiment of the present invention described above, the moisture absorption amount and the moisture release amount were tested in the same manner as the constant humidity storage test according to the first embodiment. That is, after being left in an environment of 20 ° C. and 55% RH, the equilibrium state was confirmed, the time change of the moisture absorption amount when transferred to the environment of 20 ° C. and 80% RH was measured. Further, as a comparative example, a conventional storage was similarly tested. The result of the amount of moisture absorption is shown in FIG. The result of moisture absorption measurement (for example, taking 96 hours as an example) shows that the moisture absorption amount is 190 g / m ² , which is much better than the conventional storage of 58 g / m ² . After confirming the equilibrium state by leaving it in an environment of 20 ° C. and 55% RH, the time change of the amount of moisture released when it was transferred to the environment of 20 ° C. and 35% RH was measured. As a comparative example, the same conventional storage was similarly tested. The result of the amount of moisture released is shown in FIG. Moisture release measurement (for example, taking 96 hours as an example) shows that the amount of released moisture is 125 g / m ^2.
It can be seen that it is much better than the conventional storage of 44 g / m ² . In addition, when the acid / alkali measurement was performed on the constant humidity storage according to the second embodiment,
It was in the neutral range. This is an optimum measurement value for a storage that stores art objects.

As described above, the wood-based humidity conditioner is used as the wall surface material 240 of the storage in the second embodiment, since these are industrial products, the cost can be kept low and a steady material supply can be achieved. This is also because it is a soft material that also has a high moisture absorbing / releasing performance that alleviates humidity fluctuations and that can absorb impact. Although the wood-based humidity control material lacks the warmth of natural wood grain, the drawback is solved by attaching a spruce veneer. Further, the reason why the inorganic humidity control plate is used for the wall base material 230 is to utilize the characteristics that the cost is low and the moisture absorption rises quickly.

As a modified example of the second embodiment,
If a wood-based plywood with aluminum foil on one side is provided with at least the stud side on the aluminum foil between the wall base material 230 and the stud 101, the space between the concrete and the surface material becomes double, It is possible to obtain a constant humidity storage in which harmful components generated from concrete are less likely to enter the storage space.

Next, FIG. 23 shows a third embodiment of the present invention.
~ It demonstrates based on FIG. FIG. 23 is a cross-sectional perspective view of the constant humidity storage of the third embodiment. In the figure,
Reference numeral 30 denotes a constant humidity storage according to the third embodiment, which is roughly divided into a floor portion 32, a wall portion 33, and a ceiling portion 37. The floor 32 has the same configuration as the floor 12 in FIG. 1 and the ceiling 37 has the same configuration as the ceiling 17 in FIG. The wall portion 33 is different from the first and second embodiments. The wall 33 of the third embodiment includes a base material 330,
An elongated through plate 336 fixed on the base material 330
And a surface material 340 fixed on the elongated through plate 336.
It consists of and. Hereinafter, a specific configuration of the wall portion 33 according to the third embodiment of the present invention will be described.

The base material 330 is the second embodiment (see FIG. 19).
It is the same as the wall base material 230 of (a). That is, the base material 330 is made of, for example, an inorganic humidity control material having a length of 1800 mm, a width of 900 mm, and a thickness of 12 mm, and an aluminum foil 232 is attached to the entire back surface (light iron stud 103 side).
In addition, it is treated with a poly-film coating to make it impermeable, so that harmful components generated from concrete do not enter the storage space. The base material 330 is fixed to the light iron stud 103 fixed to the lightweight steel frame base 101 with screws. The base materials 330 are arranged in a horizontal and vertical direction by butting. In addition, the long through plate 33
6 is continuously arranged from near the floor portion of the base material 330 to near the ceiling portion, and is arranged on the base material 330 at a predetermined interval (for example, 300 mm pitch) in the lateral direction. . The surface material 340 uses the same natural material as that of the first embodiment, but unlike the first embodiment in which actual processing is performed, it is a long plate of natural material with a square cross section without actual processing. Is different. This long surface material 340 is horizontally fixed across the plurality of long through plates 336. Fixing is performed by using a bis and urethane adhesive, and the adjacent wall surface members 240 in the horizontal direction are fixed butted.
Adjacent surface materials in the vertical direction are spaced apart by a predetermined distance (for example, 5 mm) to form a gap 337, and watermarking is performed.

FIG. 24 schematically shows the wall portion of the third embodiment constructed as described above. The air flow enters the base material 330 and the surface material 340 from the room through a gap 337 at a predetermined interval, and the base material 330 and the surface material 3
Heading toward the air outlet through 40. Like this third
Also in this embodiment, since the air flow is generated on the back side of all the surface materials 340, the humidity control effect is improved.

In FIG. 24, the long surface material 340 is drawn so as to be fixed over the two long through plates 336, but in reality, a large number of long surface materials 340 (5 to 5). 6
Since it is fixed by straddling the long type through plate 336 of (book),
It takes time and effort to install these on site. Therefore, as shown in FIG. 25, if this is mass-produced in a factory as an integrated panel in the shape of a cage, not only can the installation time and labor costs be saved locally, but it can also be done manually. It's convenient because you don't have to worry about uneven mounting.

In the above, as the surface material 340, a long plate having a square cross section is used as shown in FIG. 26 (a), but the third embodiment is not limited to this, as shown in FIG.
A cross section having a parallelogram shape as shown in FIG.
You may use the thing of the irregular parallelogram shape whose cross section like (c). In particular, when a parallelogram shape or an irregular parallelogram shape is used, the base material 330 and the elongated through plate 336 cannot be seen straight from the room, so that the aesthetic appearance is improved.

In the third embodiment of the present invention, Japanese cedar is used for the wall surface material 340 of the storage as in the case of the first embodiment. It is a moisture-releasing material, a soft material that can absorb impact, and is warm, and it is a safe material that does not contain artificial ingredients, and it is possible to minimize quality variations by constant material supply. Because. In addition, the reason why the inorganic humidity control plate is used for the base material 330 is to utilize the characteristics that the cost is low and the moisture absorption rises quickly.

A constant humidity storage according to the third embodiment of the present invention was tested. As in the case of the first and second embodiments, the test was carried out by leaving the constant humidity storage room in an environment of 20 ° C and 55% RH and confirming the equilibrium state, and then at 20 ° C and 8%.
The time change of the moisture absorption amount when transferred to the environment of 0% RH was measured. As a comparative example, a conventional storehouse was similarly tested.
The result of the amount of moisture absorption is shown in FIG. Moisture absorption measurement (for example, taking 96 hours) shows that the moisture absorption is 218 g /
m ^2, and consequently the film can be seen better than storehouse of another embodiment of the. After confirming the equilibrium state by leaving it in an environment of 20 ° C and 55% RH,
The time-dependent change in the amount of moisture released when transferred to an environment of 5% RH was measured. As a comparative example, the same conventional storages A and B,
Storage C from American cedar imports was also tested. The result of the amount of moisture released is shown in FIG. Moisture release measurement (for example, 96 hours) shows that the amount of moisture released is 147.
It is g / m ² , which is better than the storages of the other embodiments described above. The acid / alkali measurements were in the neutral range.
