Floating flap gate
The present invention simplifies a frame constituting a door body and reduces the manufacturing precision and assembly precision of the door body to reduce manufacturing hours. A floating flap gate 1 is installed on a road surface rs at the inlet portion of a building or underground space. The floating flap gate 1 is configured from a bottom fitting 5 in which a vertical swinging bearing part provided on the base-end side of a door body 4 is attached to a base-end part 4a of the door body 4, a resin plate 6 for supporting the door body 4 when the door body 4 is vertical, a water-blocking membrane 13 for covering the bottom fitting 5 and the resin plate 6, a first restraining plate 14 attached to a portion of the water-blocking membrane 13 covering the bottom fitting 5, and a second restraining plate 16 attached to a portion of the water-blocking membrane 13 covering the resin plate 6. The bottom fitting 5 has a length equal to the width of the door body 4, and forms a protruding circular arc surface 5a on a projecting portion 5b of the corner part on the base-end side of a surface 4d of the door body 4. The resin plate 6 has a length equal to that of the bottom fitting 5, and has a recessed circular arc surface 6a that matches the protruding circular arc surface 5a of the bottom fitting 5.
