供する。[Detailed Description of the Invention] Second Field of Application of the Industrial Industry> The present invention relates to a moisture absorption unit placed under a floor to absorb moisture from mixed air, and is capable of maintaining a high moisture absorption effect without being affected by water vapor from the underside of the floor. Moreover, we provide something that makes the laying work easier.

クリート側壁などで覆って、一辺が肩幅程度の矩形の出
入り口を空けただけのものが多く、風通しが不良なため
に多湿になりがちで、木材腐朽菌の繁殖や湿気を好む白
アリによる被害の原因となっている。Conventional technology: In the past, the area under the floor was an atrium, but recently many have been covered with concrete side walls and left with a rectangular doorway about shoulder width on one side, resulting in high humidity due to poor ventilation. This can lead to the growth of wood-decaying fungi and damage caused by termites, which like moisture.
そこで、従来では、素灰、天然軽石、石灰などの吸湿剤
を床下面に直接撒いて、床下空間の湿度を低減する方式
を採っていた。Therefore, in the past, a method was adopted to reduce the humidity in the space under the floor by directly scattering a moisture absorbent such as raw ash, natural pumice, or lime on the underfloor surface.

和状態になってもはや吸湿しなくなってしまう。Problems to be Solved by the Invention> However, in the above-mentioned conventional technology, although the moisture absorbent can initially absorb moisture and maintain the degree of d in the underfloor space at a low level, as time passes, priority is given to water vapor generated from the ground under the floor. Because it absorbs so much moisture, its ability to absorb moisture gradually decreases until it reaches a saturated state and no longer absorbs moisture.
従って、床下を長期に亘り低湿度に維持することは困難
である。Therefore, it is difficult to maintain low humidity under the floor for a long period of time.
本発明は、床下地盤の水分に影響されずに床下を長期に
低混度に維持することを技術的課題とする。The technical objective of the present invention is to maintain a low mixing level under the floor for a long period of time without being affected by the moisture in the subfloor ground.

Place it near the center of the moisture-proof sheet material 1, and the moisture-proof sheet material 1 is 2.5m"
This is a moisture-absorbing sheet for underfloor use, which is characterized by having the following dimensions:

〈作用〉
透湿シート材２を上にし、防湿シート材１を下にした状
態で、当該床下用吸湿シートを複数枚置いて床下面に敷
き詰める。<Function> With the moisture-permeable sheet material 2 facing up and the moisture-proof sheet material 1 facing down, a plurality of the moisture-absorbing sheets for underfloor use are placed and spread over the underfloor surface.
この場合、第３及び４図に示すように、吸湿シート同士

湿シートの耳部４をオーバラツプさせて、床下地盤から
床下空間への水蒸気の移動を遮断する。In this case, as shown in Figures 3 and 4, the ears 4 of the adjacent moisture absorbing sheets are overlapped to prevent the underfloor surface from being exposed between the moisture absorbing sheets, so that water vapor can flow from the subfloor ground to the underfloor space. Block movement.
この結果、吸湿剤３はもはや床下地盤の水分に影響され
ることなく、床下空間の湿気だけを吸湿することになる
。As a result, the moisture absorbent 3 is no longer affected by the moisture in the underfloor ground and absorbs only the moisture in the underfloor space.
しかも、吸湿シートはそのまま床下面に置いて行くだけ
で良いので、従来技術のように、床下面に均一に吸混剤
を撒く必要はなく、操作が簡単になる。Moreover, since the moisture-absorbing sheet can simply be left on the underfloor surface as it is, there is no need to uniformly spread the absorbent mixture over the underfloor surface as in the prior art, which simplifies the operation.
そのうえ、例えば、床下面を一枚で覆うように吸湿シー

て床下に敷き詰める場合には、吸屓ンートを筒状に巻い
て床下に入れたのち、狭い床下空間内で当該筒状シート
を解いて床下面の全体に展開しなければならないので、
作業がかなり煩雑になる。In addition, for example, if you want to form a large moisture-absorbing sheet so as to cover the underfloor surface with one sheet and place it under the floor by entering it through a narrow doorway about shoulder width, you can roll the absorbent sheet into a cylindrical shape and place it under the floor. Since the cylindrical sheet must be unraveled and spread over the entire underfloor surface within the narrow underfloor space,
The work becomes quite complicated.
これに対して、本発明の吸湿シートは２．５ｍ”以下の
大きさに設定されるので、肩幅程度の狭い出入り口から
でも床下に容易に出し入れができるうえ、筒状にしたシ
ートを解いて展開する作業もなく、吸混／一トを順番に
置いていくだけなので、床下空間内での敷き詰め作業も
楽にできる。In contrast, the moisture-absorbing sheet of the present invention is set to a size of 2.5 m" or less, so it can be easily taken in and out of the floor even through a doorway as narrow as shoulder width, and can be unfolded by unrolling the cylindrical sheet. There is no need to do any additional work, just place the suction/mixing/topping in order, making it easy to spread the material in the space under the floor.
〈発明の効果〉
（１）床下面の水分を防混シート材で完全に遮断するこ
とにより、吸混剤はもはや床下地面の水分に影響される
ことなく、床下空間の湿気だけを吸湿することができる
ので、長期に亘り床下空間の湿度を低く維持できる。<Effects of the Invention> (1) By completely blocking the moisture on the underfloor surface with the mixture-proof sheet material, the mixture absorbent is no longer affected by the moisture on the subfloor surface and absorbs only the moisture in the underfloor space. As a result, the humidity in the underfloor space can be maintained low for a long period of time.
（２）吸湿シートは吸湿剤をシートと一体に加工してい

シートの床下面への敷き詰め操作が簡便・迅速にできる
。(2) The moisture-absorbing sheet has a moisture-absorbing agent integrated with the sheet and is set to a size that is convenient for work, so the operation of spreading the sheet on the underside of the floor can be done easily and quickly.

《実験例）
床下面を一辺１．７３２ｍの正方形（面積３ｍ２）に形
成し、その周囲を厚さ１０ｃｍ、高さ５０ｃｍのコンク
リート壁で仕切り、その上部を合板で覆った床下部屋Ｐ
−Ｑ−Ｒを３室用意し、各部屋の当初の湿度を略同一に
設定し、温度を４〜７゜Ｃに夫々保持した。 一つの床
下部屋Ｐに４枚の上記吸湿シート５を敷き詰め、耳部４
をオーバラツプさせて床下面の全体を覆い、床下部屋の
相対湿度の経時変化を測定した。[Experiment example] An underfloor room P where the underfloor surface is formed into a square with sides of 1.732m (area: 3m2), the surrounding area is partitioned with a concrete wall 10cm thick and 50cm high, and the upper part is covered with plywood.
-Q-R was prepared in three rooms, and the initial humidity in each room was set to be approximately the same, and the temperature was maintained at 4 to 7°C. Four of the above-mentioned moisture absorption sheets 5 are spread in one underfloor room P, and the ear portion 4 is
They were overlapped to cover the entire underfloor surface, and changes in relative humidity in the room under the floor over time were measured.
この場合、当該吸湿シート５は一辺１ｍの正方形である
ので、耳部４のオーバラップ幅は２６． ８ｃｍとなり
、４枚の吸湿シート５に封入されるセピオライト粒の全
量は２０ｋｇになった。In this case, since the moisture-absorbing sheet 5 is a square with a side of 1 m, the overlap width of the ears 4 is 26. 8 cm, and the total amount of sepiolite grains enclosed in the four moisture absorbing sheets 5 was 20 kg.
但し、他の床下部屋Ｑの床下面にセピオライト粒４０ｋ
ｇを直接的に撒いたものを比較例とした。However, there are 40k sepiolite grains on the underfloor surface of the other underfloor room Q.
A comparative example was one in which g was directly sprinkled.
また、残りの床下部屋Ｒはそのままの状態にして、相対
湿度の経時変化を測定して基準例とした。In addition, the remaining underfloor room R was kept as it was, and changes in relative humidity over time were measured and used as a reference example.
第５図はその結果を示し、全期間に亘り本発明の吸湿能
力が比較例を上回り、特に、５日以後ではその傾向が顕
著になることが判る。FIG. 5 shows the results, and it can be seen that the moisture absorption ability of the present invention exceeds that of the comparative example over the entire period, and this tendency becomes particularly noticeable after 5 days.
即ち、比較例では、床下面からの水蒸気の影響で床下部
屋の吸湿効果が日数を経るにつれて低下していくのに対
し、本発明では３０日経過時点でも、初期に示す低湿度
を概ね保持できることが判る。That is, in the comparative example, the moisture absorption effect of the underfloor room decreases over time due to the influence of water vapor from the underfloor surface, whereas in the present invention, the initial low humidity can generally be maintained even after 30 days have passed. I understand.
