FLOATING BODY TYPE FLAP GATE
To prevent deflection on a door body tip part even when assistance such as counterweight is needed and a span of an installation place is wide.SOLUTION: A floating body type flap gate 1 is configured so that a tip side 2c can be rotatably floated with a base end side as a supporting point. The flap gate includes an upper girder 2d mounted on the tip side 2c of a door body 2 and a beam 3 for door body suspension of which both ends are connected to one ends of a wire rope 4. A counterweight 5 as tensile means is connected to the other end side of the wire rope 4. A bolt 6b is interposed between the upper girder 2d and the beam 3 for door body suspension by insertion of a bolt 6a which is interposed between the upper girder 2d and the beam 3 for door body suspension and is provided on the upper surface of the upper girder 2d as an adjustment member for making a reaction force against a tension force of the wire rope 4 by the counterweight 5 applied to the beam 3 for door body suspension when the door body falls down evenly act on the upper girder 2d.SELECTED DRAWING: Figure 1
【課題】カウンタウエイトなどの助力を必要とし、設置場所の径間が広い場合であっても扉体先端部にたわみが生じないようにする。【解決手段】先端側２ｃが基端側を支点として回転浮上可能に構成した浮体式フラップゲート１である。扉体２の先端側２ｃに取り付けられた上部桁２ｄと、両端部がそれぞれワイヤロープ４の一端と連結される扉体吊用梁３とを備える。ワイヤロープ４の他端側には引張手段としてカウンタウエイト５が連結されている。上部桁２ｄと扉体吊用梁３との間に介在し、扉体倒伏時、扉体吊用梁３にかかるカウンタウエイト５によるワイヤロープ４の張力に対する反力を上部桁２ｄに等分に作用させるための調整部材として、上部桁２ｄの上面に設けられたボルト孔６ａに差し込むことにより、上部桁２ｄと扉体吊用梁３の間に介在させるボルト６ｂを有する。【選択図】図１
