い。(c) Conventional technology and its problems Conventionally, unlike outdoor pools, indoor pools are often heated pools for use in all seasons, and generally have a room temperature of around 30°C and a relative humidity of 90 to 95.
% environment. For this reason, interior materials for indoor pools must have excellent water resistance.
特に、天井面は直接水がかからない部位である
が、高湿条件下で長期間されされるため、耐湿性
（即ち、湿気で天井材が変形したり、強度低下や
腐朽を生じない性質）に優れていることが要求さ
れる。 In particular, the ceiling surface is an area that is not directly exposed to water, but because it is exposed to high humidity conditions for long periods of time, it has poor moisture resistance (i.e., the property that the ceiling material does not deform, lose strength, or rot due to moisture). Excellence is required.

ーコストが高いうえに、反響音が大きくてうるさ
かつた。 However, conventional ceiling structures have poor thermal insulation and sound absorption properties, resulting in high energy costs for maintaining room temperature and large, noisy echoes.
また、室内プールは消毒のために屋外プールよ

ので、酸に弱い金属を天井面の仕上げパネルに使

ルが腐蝕しやすいという問題点があつた。 In addition, indoor pools often have a larger amount of chlorine added to them than outdoor pools for disinfection purposes, so if acid-resistant metals are used for ceiling finishing panels, the chlorine in the moisture may There was a problem that the panels were easily corroded.

繊維板は使用出来なかつた。 On the other hand, in view of the above-mentioned problems, by constructing as a ceiling material an inorganic fiberboard made of rock wool or glass wool, which has excellent heat insulation, sound absorption, and fire resistance, and does not easily rot even when absorbed by water, as a ceiling material. It is conceivable to form a surface.
In addition, conventional ceiling materials such as Rockwool sound-absorbing boards are formed using starch as a binding agent, which exhibits excellent binding strength in small amounts, so if used in humid areas such as swimming pools, starch may It has been impossible to use starch binder inorganic fiberboard, which has traditionally been used in general buildings, because it absorbs moisture, significantly lowering its binding strength and causing mold to grow.

含まれた塩素によつて天井裏の鋼製天井下地材が
錆を生じやすく、腐蝕しやすいという問題があつ
た。 In addition, since the ceiling material made of inorganic fiberboard is porous, moisture permeates through the attic to a large extent, and condensation is likely to occur in the space behind the attic. Metal underlayment is used for this purpose, but as mentioned above, in ceiling materials that allow moisture to easily permeate, the steel ceiling underlayment behind the attic tends to rust due to condensation water and chlorine contained in the moisture. The problem was that it was easily corroded.

という問題点があつた。 Moreover, in order to prevent the corrosion, the attic space must be frequently ventilated to remove permeated moisture, and a large amount of power is required for forced ventilation, which poses a problem.

力を節約することができる。(E) Function and Effect Therefore, according to the present invention, an inorganic board having a moisture-proof layer on at least one side is pasted as a backing material on the lower surface of a metal ceiling base material, and this Since the joints of the adhesive are sealed with a sealant, the moisture-proof layer of the sealant and waste adhesive prevents moisture from entering the ceiling. As a result, the ceiling base material located in the attic space is less likely to be corroded by moisture from the pool, improving the durability of the ceiling base material, and saving the power required for forced ventilation of the attic space. Can be done.

It is something. It goes without saying that the moisture-proof layer 2b may be provided on the upper surface of the inorganic plate 2a or on its upper and lower surfaces. According to the latter, the moisture resistance is further improved, and the mechanical strength of the inorganic plate 2a does not decrease due to water absorption.

So, when we measured the amount of moisture permeation, the amount of moisture permeation per 1 m 2 per hour was 0.12 g/m 2 Hr, and even if we looked at the entire ceiling of a 25 x 25 m pool, the amount of moisture permeation was 75 g/hour. The amount of moisture was sufficient to be removed even by natural ventilation.
