PROBLEM TO BE SOLVED: To provide a floating body for tsunami evacuation by which a user can rapidly evacuate, and which is close to the user, safe, simple, inexpensive, and non-rotatable in the water, even when a large tsunami of which height is 10 meters up to 34 meters attacks in three minutes after a giant earthquake.SOLUTION: A floating body for tsunami evacuation disposed at a room in a robust building, a rooftop thereof, or outside thereof is a bag-shaped forming body excellent in breakage resistance, waterproofness, and airtightness with a convexity at the top and an aperture 2 at the bottom. The floating body for tsunami evacuation is provided in which air quantity required for survival is secured, a person takes refuge inside, air in an upper portion thereof enables the floating body to float in the water even though allowing the inside of the floating body to be flooded from the aperture at the bottom, and height of an air retention part is 2.5 m or less for keeping stability. The floating body for tsunami evacuation at the room in the robust building limits flotation at the ceiling of the room, and suppresses rotation thereof by a crimping force consisting of buoyancy and reaction force from the ceiling in a vertical direction, and adhesion force on the ceiling surface so that an up and down position is kept and loss of the air quantity required for survival is prevented.
【課題】巨大地震の3分後に来襲する高さ10m、最大34mの大きな津波にも、個人が迅速に避難できる身近、安全、簡易、安価で、水中で回転不可の津波避難用浮遊体を提供する。【解決手段】堅固な建物の部屋、屋上、もしくは屋外に設置する津波避難用浮遊体は、耐破損性、防水性、および気密性に優れた上に凸で、下に開口2を有する袋状の形成体で、生存必要空気量を確保し、内部に人が避難し、水中では下部の開口から浸水を許すものの上部の空気で浮上し、安定を保つため水中での空気保有部の高さを2.5m以下としたことを特徴とする。また、前記津波避難用浮遊体は、堅固な建物の部屋では、天井までで浮上を制限し、かつ浮力と天井による反力との上下方向の圧着力、および天井面との密着力で回転を抑制することで、上下の体勢を維持し生存必要空気量の逸失を防止することを特徴とする。【選択図】図4
