Abstract: The present invention provides a floating flap gap which has a door body with a forward end which is able to swing upwards, in a direction in which the water flows into an opening or at an access way, around a base end thereof serving as a fulcrum. The door body is attached to one end of a wire rope, and an auxiliary force generating means is attached to the other end thereof. This structure makes it possible to prevent an overflow during the initial influx of water and to enhance the ability of the door body to follow the water level when the door body begins to lower. This structure additionally makes it possible to mitigate a shock which occurs when raising of the door body is completed and when lowering of the door body is completed.

Abstract: A land-mounted flap gate formed by arranging and connecting a plurality of door bodies alongside one another is disclosed. The front side of each of the plurality of door bodies is raised and lowered using the back end side of each door body as a support point. One end of a rope is attached to the back end surface of the door body and the other end of the rope is attached to a counter weight. At least one fixed pulley for guiding the rope is disposed below the back end side of the door body such that the counter weight assists the raising or lowering when starting the raising or lowering and acts as a resistance against the raising or lowering before completing the raising or lowering. The waterproof film that seals a space between neighboring door bodies in a waterproof manner is formed in a substantially trapezoidal shape.

Abstract: To provide a floating flap gate that requires an auxiliary force of a counterweight or the like, and in which bending does not occur in a forward end portion of a door body, even in cases in which an installation site has a wide span. A floating flap gate 1 having a forward end portion 2c of a door body 2 that is configured to rotate around a base end portion serving as a fulcrum at a time of a rising water, so as to float upwards, and provided with an upper beam 2d attached to the forward end portion 2c of the door body 2 and a door body suspension member 3 contained within the upper beam 2d, and having two ends each being connected to one end of a wire rope 4. A counterweight 5 is connected to the other end side of the wire rope 4 as a pulling device. Bolts 6b are used as adjusting members interposed between the upper beam 2d and the door suspension member 3, and are inserted into bolt holes 6a provided on an upper surface of the upper beam 2d, so as to exert an opposing force to the tension of the wire rope 4 resulting from the weight of the counterweight 5 acting on the door body suspension member 3, the opposing force being applied uniformly to the upper beam 2d during ordinary use.
