Description

TECHNICAL FIELD The present invention relates to a water stop plate and an under floor vent part with a water stop function for preventing water from entering through an opening such as an under floor vent installed in a base of a general house.

Recently, unprecedented disasters have occurred around the world due to the appearance of abnormal weather, torrential rains and powerful typhoons, and underfloor and underfloor flooding has been reported. In the Fukui torrential rain from dawn on July 18, 2004, 3,433 households were flooded on the floor and 8,071 households were flooded under the floor. Furthermore, in Typhoon No. 23, which traversed Japan from October 20 to 22, 2004, there were 25 households flooded on the floor and 288 households flooded under the floor in Fukui Prefecture, and 8,000 households in the Toyooka area of Hyogo Prefecture. It has been reported that it has been immersed in water.
The above-mentioned damage is an example, but underfloor inundation occurs several times on the floor.
However, once water enters the floor, it will take a huge amount of labor and costs for restoration work such as white ant countermeasures and disinfection, removing the floorboard, drying the foundations and soils that support the floor, just like flooding on the floor. Currently.
However, flood damage countermeasures such as torrential rain are mainly for flooding countermeasures such as river breaks and drainage and underground passages. However, no specific proposal or suggestion has been found for the prevention of underfloor inundation, although everyone is requested.
