Description

  The present invention relates to an underfloor humidity control mat that is used by being laid on a floor base in order to adjust the humidity of an underfloor space.

The underfloor space tends to be humid due to evaporated water from the soil, which promotes the growth of wood-rotting fungi and causes damage by termites that prefer moisture. There is also a peculiar odor due to the retention of air.
Therefore, conventionally, a hygroscopic agent is directly sprayed on the floor surface to dehumidify the moisture in the underfloor space.
Conventionally, a humidity control mat for a floor having a mat bag body in which a non-moisture permeable sheet material is used as a lower sheet material and the moisture permeable sheet material is used as an upper sheet material, and a moisture absorbent is accommodated in the mat bag body. Has been proposed (see Patent Document 1).

  However, in the case where the hygroscopic agent is sprayed directly on the floor surface as in the former, the hygroscopic agent can initially absorb the moisture and dehumidify the moisture in the underfloor space, but in order to directly absorb the water vapor generated from the floor surface, There was a problem that the moisture absorption capacity gradually decreased and became saturated in a short time, making it difficult to maintain the underfloor space at low humidity for a long time.

  In the latter under-floor humidity control mat, the humidity in the under-floor space can be adjusted and maintained at a low humidity by the humidity control material housed inside the mat bag body. Further, on the lower surface of the mat bag body, a ventilation space is formed on the outer side of the mat bag body along the polymerization joining portion, and a ventilation hole is formed in the polymerization joining portion from the ventilation space to the upper surface side of the mat bag body. Therefore, although the condensation of the lower sheet material due to the water-impermeable sheet can be reduced, the occurrence of condensation has not been sufficiently suppressed.

Therefore, when the conventional humidity control mat for the underfloor is laid on the floor base surface, the water vapor evaporated from the floor base surface may cause dew condensation on the surface of the lower sheet material, which may cause mold. Was leaving.
