FLOATING-BODY-TYPE FLAP GATE
PROBLEM TO BE SOLVED: To provide a floating-body-type flap gate that simplifies a frame constituting a door body, and reduces the number of manufacturing steps by lowering manufacturing accuracy and assembly accuracy for the door body.SOLUTION: A floating-body-type flap gate 1 is installed on a road surface rs at an entrance of a building or an underground space. An erected and swinging support part disposed on a base edge side of a door body 4 includes: a bottom part metal fitting 5 fitted on a base edge part 4a of the door body 4; a resin plate 6 supporting the door body 4 when the door body 4 is erected; a water cutoff film 13 covering the bottom part metal fitting 5 and the resin plate 6; a first holding plate 14 fitted on a part of the water cutoff film 13 that covers the bottom part metal fitting 5; and a second holding plate 16 fitted on a part of the water cutoff film 13 that covers the resin plate 6. The bottom part metal fitting 5 has a length that equals a width of the door body 4, and has a protruding arcuate surface 5a formed on a protrusion 5b at a corner on the base edge side of a surface 4d of the door body 4. The resin plate 6 has the same length as the bottom part metal fitting 5, and has a recessed arcuate surface 6a that fits the protruding arcuate surface 5a of the bottom part metal fitting 5.SELECTED DRAWING: Figure 2
【課題】扉体を構成するフレームの簡略化と共に、扉体の製作精度と組立て精度を低減して製作工数を削減する。【解決手段】建物や地下空間の入口部分の路面ｒｓに設置する浮体式フラップゲート１である。扉体４の基端側に設ける起立揺動の支承部を、扉体４の基端部４ａに取付ける底部金物５と、扉体４の起立時に扉体４を支える樹脂プレート６と、底部金物５及び樹脂プレート６を覆う止水膜１３と、止水膜１３の底部金物５を覆う部分に取付ける第１の押さえ板１４と、止水膜１３の樹脂プレート６を覆う部分に取付ける第２の押さえ板１６とで構成する。底部金物５は扉体４の幅と同じ長さで、扉体４の表面４ｄの基端側の角部の突出部５ｂに凸円弧状面５ａを形成する。樹脂プレート６は底部金物５と同じ長さで、底部金物５の凸円弧状面５ａと合致する凹円弧状面６ａを有する。【選択図】図２
