WATER IMMERSION PREVENTION MEMBER, AND UNDERFLOOR WATER IMMERSION PREVENTION STRUCTURE
To provide a water immersion prevention member and an underfloor water immersion prevention structure capable of securing maintainability.SOLUTION: A water immersion prevention member 30 is formed of a material which expands in volume when absorbing water, in a plate shape, and comprises a main body portion 30A in which a vent hole 30B penetrating in a plate thickness direction is formed. When the main body portion 30A expands in volume by absorbing water, an opening area of the vent hole 30B is reduced. Thus, while air is circulated through the vent hole 30B before absorbing water, immersion of air and water is suppressed when absorbing water. Also, because the main body portion 30A has flexibility, in a state in which the main body portion 30B is bent, the water immersion prevention member 30 can be attached to a part where water immersion is prevented through a gap of a foundation 12 etc.SELECTED DRAWING: Figure 1
【課題】メンテナンス性を確保することができる浸水防止部材及び床下浸水防止構造を提供する。【解決手段】浸水防止部材３０は、吸水時に体積膨張する材質で板状に形成されており、板厚方向に貫通する通気孔３０Ｂが形成された本体部３０Ａを備えている。そして、吸水による本体部３０Ａの体積膨張時には、通気孔３０Ｂの開口面積が縮小される。このため、吸水前の状態では、通気孔３０Ｂを通じて空気を通気させつつ、吸水時には、空気及び水の浸入が抑制される。また、本体部３０Ａが可撓性を有しているため、本体部３０Ａを撓ませた状態で基礎３０の隙間などから浸水を防止する部分に浸水防止部材３０を取付けることができる。【選択図】図１
