VENTILATION HOLE IMMERSION PREVENTION DEVICE
To provide a ventilation hole immersion prevention device with which, when blocking the ventilation hole with a board, the board is evenly in close contact with the ventilation hole and meanwhile the protruding direction of a hook that can lock on the grid can be easily identified.SOLUTION: A ventilation hole immersion prevention device consists of: a water-stop that is larger than a ventilation hole and has a first through hole; a packing provided around the surface of the water-stop on the underfloor space side; a pressing board which is provided on the outer side of the water-stop and has a second through hole that overlaps with the first through hole, and in which an extending part that has extended from around toward the water-stop abuts on the water-stop; and a fixing part that fixes the water-stop to the ventilation hole. The fixing part consists of an L-shaped hook part, a male thread part, a female thread part, a ring packing and a mark part. The male thread part penetrates the first through hole and the second through hole, and the hook part is arranged at the end of the male thread part on the underfloor space side. On the outer side of the male thread part the ring packing is passed through, the female thread is screwed in, and the female thread part energizes the ring packing to the pressing plate, and the mark part indicates the direction of the protruding part of the hook part.SELECTED DRAWING: Figure 1
【課題】換気口を板で塞ごうとした際、換気口と板が均一に密着すると共に、格子に係止し得るフックの突出方向を容易に判別し得る換気口浸水防止装置を提供する。【解決手段】換気口よりも大きく、第１の貫通孔のある止水板と、止水板の床下空間側の面の周囲に設けられたパッキンと、止水板の屋外側の面に設けられ、第１の貫通孔と重なり合う第２の貫通孔を持ち、周囲から止水板方向に延出した延出部が止水板と当接する押圧板と、止水板を換気口に固定させる固定部から成り、固定部は、Ｌ字型のフック部と、雄ねじ部と雌ねじ部とリングパッキンと目印部から成り、雄ねじ部は、第１の貫通孔及び第２の貫通孔を遊貫し、フック部は、雄ねじ部の床下空間側の端部に配置され、雄ねじ部の屋外側には、リングパッキンが通され、雌ねじ部がねじ込まれ、雌ねじ部は、リングパッキンを押圧板に付勢し、目印部は、フック部の突出部の方向を示すという構成を採用した。【選択図】図１
