【従来技術】ゴム堰も大型のものになるとゴム堰本体を
一度に加硫して製造するには大型の設備を必要として設
備面でもコストがかかり、また山間の奥地等の現場では
ゴム堰本体を運搬するだけでも容易ではない。
【０００３】そこでゴム堰本体を周方向に亘って分割し
た本体分割部分を予め製造し、これを継ぎ合わせること
で本体を製造する方法が従来から提案されており、その
従来例（特公平３-35098号公報）について、図８に図示
し説明する。
【０００４】加硫成型したゴム堰本体分割部分01の端縁

コストがかかる。
【０００６】またゴム堰本体分割部分01の端縁を精度良
く除去しないと予め加硫したゴムシート02が未加硫ゴム
03を介在させたとしても精度良く嵌合せずすき間04がで
きるおそれがあるとともに、未加硫ゴム03の量調節が悪
いとやはりすき間04ができ、剥離破壊の原因となる。
【０００７】さらにゴム堰本体部分01どうしは予め加硫
した補強材入りゴムシート02を介して加硫接着される
が、この加硫時にゴムシート02は再び加硫を受けること
になり、過加硫により物性が剛性化し継目部分のみ剛性
の高い平板部が形成されて、ゴム堰本体は起立時に滑ら
かな湾曲形状を構成しにくくなる。
【０００８】本発明はかかる点に鑑みなされたもので、
その目的とする処は製造工程の一部を削減し設備を大型
化することなく精度良くゴム堰本体部分を接着すること
ができるゴム堰本体の製造方法を供する点にある。
【０００９】
【課題を解決するための手段および作用】上記目的を達
成するために、本発明は、流体の送入により起立し排出

【００１０】補強帆布入りゴムシートは未加硫のものを
用いるので、その分工数が削減され、またゴム堰本体分
割部分の除去面を精度良く形成しなくとも補強帆布入り
ゴムシートは未加硫なので、嵌合してなじみ易くすき間
を埋めて剥離破壊を防止できる。
【００１１】未加硫のゴムシートによりゴム堰本体分割
部分を継ぎ加硫接着するので過加硫部分を生じず全体で
略均質なゴム堰本体を製造できる。
【００１２】
【実施例】以下図１ないし図５に図示した本発明の一実
施例について説明する。本実施例は製造されたゴム堰本
体が折り返された構造のもので、まず図１に示すように
ゴム堰本体をなす上下の本体分割部分１を予め製造す
る。
【００１３】ゴム堰本体分割部分１は長方形の板状をな
し、折り返しの分割部分１ａは長方形板状のものを２重
に折り返した形状をしている。かかる形状のゴム堰本体
分割部分１、１ａを加硫成型して予め製造する。
【００１４】次に互いに接合するゴム堰本体分割部分１
の接合部分を埋設されている補強帆布ごとに順次幅を狭
くして階段状に剥ぎ取っていく（図２参照）。この剥ぎ
取った面をかるくバフ掛けし厚さ0.5 mm位の薄いゴムシ
ートを前面に亘り貼りつける。
【００１５】次に相互にゴム堰本体分割部分１どうしを
その端縁で接すると図３に示すように剥ぎ取った除去部
分は当接面を中央に順次幅を広くして段差を形成してお
り、図３に示すゴム堰本体分割部分１において下層の除
去部分から上層に向け未加硫の補強帆布入りゴムシート
２を順次嵌合積層していく。
【００１６】上層に行くにしたがい、順次幅の広い補強
帆布入りゴムシート２が用いられるが、すき間が生じた
場合は準備されている未加硫のゴムシートまたはゴム糸
を使ってすき間を埋める。そして最上層には全体の厚み
を調整するために外層の未加硫ゴムシート３を積層す
る。
【００１７】こうして互いの継目に補強帆布入りゴムシ
ート２、３を嵌合して継ぎ合わせた上側のゴム堰本体分
割部分１と下側のゴム堰本体分割部分１とを離型シート
４を挟んで重ね合わせる（図４参照）。
【００１８】一方の端部は折り返しの本体分割部分１ａ
が継ぎ合わされて、その上下シートに順次ゴム堰本体分
割部分１が継ぎ合わされて、他方の端部は開放端となっ
ている。
【００１９】上下の継目は同じ位置にあり、この継目を
加硫用熱板５が上下から挟みつけ加硫接着を行う。この
ように上下同時に加硫接着していく。
【００２０】こうして出来上がったゴム堰本体10は河川
を横切って河床部分に上下の開放端部を重ねて上流側に
向け固着する。袋状をなすゴム堰本体10の内部に流体を
送入することでゴム堰本体10は膨張し図５に示すように
起立して河の流れを規制し、流体を排出することで倒伏
して流れを自由にすることができる。
【００２１】ゴム堰本体10は、周方向に間隔をあけて複
数本の継目11が幅方向に指向して走っているが、未加硫
のゴムシート２、３を加硫接着したので、継目だけが加
硫が過ぎて剛性が高くなっているようなことはなく、全
体に概ね均質な物性を備え、起立時には滑らかな湾曲を
形成して河の流れの調整に支障を生じさせない。
【００２２】またゴム堰本体分割部分１、１ａの除去部
分に補強帆布入りゴムシート２を嵌合する際、補強帆布
入りゴムシート２自体が未加硫で変形して除去部分にな
じみ易いので、ゴム堰本体分割部分１、１ａの除去部分
を精度良く製造する必要がないとともに、僅かに生じる
すき間には未加硫のゴム糸などを使ってすき間を埋める
ので、内部に空隙を生じることはなく、加硫接着後剥離
破壊の原因をつくることがない。
【００２３】補強帆布入りゴムシート２は予め加硫して
製造しておく必要がないので、工数が削減され、コスト
ダウンが図れる。加硫接着する前のゴム堰本体分割部分
１、１ａを単体で現場に運び、現場近くで加硫接着作業
を行いゴム堰本体を製造することができる。
【００２４】したがって大型のゴム堰の場合でも大きな
ゴム堰本体を運搬する必要がなく、特に山間奥地や道路
等の運搬事情の悪い現場でもゴム堰の施工が可能であ
