以下、本発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、起伏堰の構成を示す説明図である。図２は、ゴム袋体部の構成を説明する説明図である。図３は、起伏堰の使用状態を示す説明図である。図４は、起伏堰のゴム袋体部の変更例を示す説明図である。   FIG. 1 is an explanatory diagram showing the configuration of the undulation weir. FIG. 2 is an explanatory view illustrating the configuration of the rubber bag body. FIG. 3 is an explanatory view showing a usage state of the undulation weir. FIG. 4 is an explanatory view showing a modified example of the rubber bag body portion of the undulation weir.

図１に示すように、起伏堰１は、河床に配設される固定ブロック３に、流体の供給／排出に応じて膨張／収縮するゴム袋体部１６，１７と、そのゴム袋体部１６，１７の膨張／収縮に連動して起伏する扉体２とを連結してなる。
そして、この起伏堰１は、河床における一段高い床面と扉体２との間に水密ゴム４を架設することで、床面と固定ブロック３との間に異物が混入することを防ぐことに加え、気密性を保持する構造となっている。 As shown in FIG. 1, the undulating weir 1 includes rubber bag bodies 16, 17 that expand / shrink in response to fluid supply / discharge on a fixed block 3 disposed in the river bed, and the rubber bag body 16. , 17 and the door body 2 that undulates in conjunction with expansion / contraction.
And this undulation dam 1 prevents water from being mixed between the floor surface and the fixed block 3 by laying a watertight rubber 4 between the floor surface of the river bed and the door body 2. In addition, it has a structure that maintains airtightness.

次に、ゴム袋体部１６は、膨張／収縮するゴム袋体１３と、一端がゴム袋体１３の外縁に沿って固定され、他端が固定ブロック３へ回転可能に連結されるコ字状のフレーム１１とで構成されている。そして、流体の供給・遮断を行う切替バルブ６と、この切替バルブ６を回すことにより、空気ポンプ７からエアー配管８を経由してゴム袋体部１６にエアーの供給を可能としている。
また、ゴム袋体部１７は、フレーム１１の柄の部分をゴム袋体部１６，１７の重ね方向で折り曲げ可能とするヒンジ機構１７ａを備えた構成以外は、ゴム袋体部１６と同様の構成であり、エアー等の流体を供給・排出することによって膨張／収縮を行う。このゴム袋体１６，１７は、ゴム袋体１３の厚み方向（膨張／収縮方向）で重なるように固定ブロック３に連結されている。 Next, the rubber bag body portion 16 has an inflated / shrinkable rubber bag body 13, one end fixed along the outer edge of the rubber bag body 13, and the other end rotatably connected to the fixed block 3. Frame 11. The switching valve 6 that supplies and shuts off the fluid and the switching valve 6 are rotated, so that air can be supplied from the air pump 7 to the rubber bag body 16 via the air pipe 8.
The rubber bag body portion 17 has the same configuration as that of the rubber bag body portion 16 except for a configuration including a hinge mechanism 17a that can bend the handle portion of the frame 11 in the overlapping direction of the rubber bag body portions 16 and 17. It expands / contracts by supplying and discharging fluid such as air. The rubber bag bodies 16 and 17 are connected to the fixed block 3 so as to overlap in the thickness direction (inflating / shrinking direction) of the rubber bag body 13.

そして、図２（ａ）に示すように、ゴム袋体１３とフレーム１１との連結は、ゴム袋体１３の縁部をフレーム１１の基端１４と固定板１２とで挟持し、ボルトで螺合することによって構成される。
フレーム１１の一対の突出端１１ａ，１１ａは、夫々の先端に形成した連結部１５を備えており、この連結部１５，１５をピン５によって固定ブロック３に軸着することで、フレーム１１は固定ブロック３へ回転可能に連結される。 As shown in FIG. 2 (a), the rubber bag body 13 and the frame 11 are connected by holding the edge of the rubber bag body 13 between the base end 14 of the frame 11 and the fixing plate 12 and screwing it with a bolt. Composed by joining.
The pair of projecting ends 11 a and 11 a of the frame 11 includes a connecting portion 15 formed at each tip, and the frame 11 is fixed by axially attaching the connecting portions 15 and 15 to the fixed block 3 by the pins 5. The block 3 is rotatably connected.

なお、ゴム袋体１３は、図２（ｂ）に示すように、まず初めに、高い空気圧にも耐え得る補強繊維が編み込まれたゴムシート１０を折り曲げて縁部を重ね合わせ、開口した状態の左右両端を、接着剤による接着や熱による溶着で塞ぐ。そして、重ね合わせた縁部にフレーム１１と連結するためのボルトの通り孔を、左右両端方向で一列となるように複数穿設している。   In addition, as shown in FIG.2 (b), the rubber bag body 13 is the state which opened the rubber sheet 10 in which the reinforcement fiber which can also endure high air pressure was folded, the edge part was piled up, and opened. The left and right ends are closed with adhesive or heat welding. A plurality of bolt holes for connecting to the frame 11 are formed in the overlapped edge so as to form a line in the left and right end directions.

以上の如く構成された起伏堰１は、以下のように使用される。まず、ゴム袋体部１６，１７にエアーを供給しない状態では、図３（ａ）に示すように、各ゴム袋体１３は収縮して河床に倒伏し、扉体２も河床に沿って倒伏している。
ここから切替バルブ６を回し、エアー配管８内にエアーを供給してゴム袋体部１６，１７にエアーの供給を行うと、ゴム袋体部１６，１７は、各ゴム袋体１３が膨張することによって厚み方向の寸法が大きくなり、それに連れて扉体２が、図３（ａ）の倒伏状態から徐々に起き上がり、各ゴム袋体１３へのエアーの供給が一杯になると、図３（ｂ）のように起立した状態となる。
反対に起伏堰１を使用しない場合は、切替バルブ６によって袋体１３，１３に蓄えられたエアーの排気を行う。すると、各ゴム袋体１３が収縮し、それに連れて扉体２が自重によって図３（ａ）の倒伏状態へ復帰する。 The undulation weir 1 configured as described above is used as follows. First, in a state in which no air is supplied to the rubber bag body portions 16 and 17, as shown in FIG. 3A, each rubber bag body 13 contracts and falls to the river bed, and the door body 2 also falls along the river bed. doing.
When the switching valve 6 is turned from here and air is supplied into the air pipe 8 and air is supplied to the rubber bag body portions 16 and 17, the rubber bag body portions 16 and 17 expand the respective rubber bag bodies 13. As a result, the dimension in the thickness direction increases, and accordingly, the door body 2 gradually rises from the lying state of FIG. 3A, and when the supply of air to each rubber bag body 13 becomes full, FIG. ) Will stand up.
On the contrary, when the hoisting dam 1 is not used, the air stored in the bags 13 and 13 is exhausted by the switching valve 6. Then, each rubber bag body 13 contracts, and with that, the door body 2 returns to the lying down state of FIG.

このように、上記形態の起伏堰１によれば、ゴム袋体部１６を、膨張／収縮するゴム袋体１３と、基端１４がゴム袋体１３の外縁に沿って固定され、突出端１１ａ、１１ａが固定ブロック３へ回転可能に連結されるフレーム１１とで形成したことで、ゴム袋体１３をフレーム１１に取り付けることにより、ゴム袋体部１６に作用する荷重モーメントが軽減されるため、ゴム袋体部１６の内圧を下げることが可能となる。そして、ゴム袋体部１６にかかる負荷が軽減されることから、ゴム袋体１３を高強度にする必要がなく、安価なゴムシート１０を選択することが可能となる。   Thus, according to the undulation weir 1 of the said form, the rubber bag body part 16 which expands / shrinks the rubber bag body part 16 and the base end 14 are fixed along the outer edge of the rubber bag body 13, and the protruding end 11a. , 11a is formed with the frame 11 rotatably connected to the fixed block 3, so that the load moment acting on the rubber bag body portion 16 is reduced by attaching the rubber bag body 13 to the frame 11, It becomes possible to reduce the internal pressure of the rubber bag body portion 16. And since the load concerning the rubber bag body part 16 is reduced, it is not necessary to make the rubber bag body 13 high in strength, and it becomes possible to select an inexpensive rubber sheet 10.

特に、フレーム１１とゴム袋体１３の外縁との固定を、フレーム１１の基端１４と、基端１４と対になる固定板１２とで外縁を挟持することで行うことで、フレーム１１とゴム袋体１３との固定が確実に行えて両者が強固に一体化する。
また、フレーム１１はコ字型で、一対の突出端１１ａ、１１ａ側が固定ブロック３へヒンジ結合され、直線状の基端１４がゴム袋体１３に固定される構造であるので、強固なフレームが得られて耐久性の向上に繋がる。
加えて、固定ブロック３が鋼製であるので、固定ブロック３がゴム製のものに比べて安全率を高く設定する必要がない。また、特殊な形状であっても安価に製作可能であることからコストを低く押さえることが可能で、取り替えも容易である。 In particular, the frame 11 and the outer edge of the rubber bag 13 are fixed by sandwiching the outer edge between the base end 14 of the frame 11 and the fixing plate 12 paired with the base end 14, whereby the frame 11 and the rubber bag 13 are fixed. The bag body 13 can be securely fixed, and both are firmly integrated.
The frame 11 is U-shaped and has a structure in which the pair of protruding ends 11a and 11a are hinged to the fixed block 3 and the linear base end 14 is fixed to the rubber bag 13, so that a strong frame is formed. Obtained to lead to improved durability.
In addition, since the fixed block 3 is made of steel, it is not necessary to set the safety factor higher than that of the fixed block 3 made of rubber. Moreover, even if it is a special shape, it can be manufactured at low cost, so the cost can be kept low and replacement is easy.

なお、本発明の起伏堰の構成は、上記実施形態の態様に何ら限定されるものではなく、ゴム袋体部の構成や袋体の形状、配置等の構成を本発明の趣旨を逸脱しない範囲で必要に応じて適宜変更することができる。   The configuration of the undulating weir of the present invention is not limited to the aspect of the above embodiment, and the configuration of the rubber bag body part, the shape of the bag body, the configuration of the bag body and the like does not depart from the spirit of the present invention. Thus, it can be changed as needed.

例えば、図４（ａ）に示すように、フレーム２１をＨ型として、一方の突出端２１ａ，２１ａ側を固定ブロック３へヒンジ結合し、他方の突出端２１ｂ、２１ｂ及び中央部２４とコ字状の固定板２２との間でゴム袋体２３を三辺で固定するゴム袋体部２６，２７とすることができる。なお、この場合のゴム袋体２３は、同図（ｂ）に示すように、袋状にしたゴムシート２０においてフレーム２１に固定される三辺を溶着することで形成される。
このように、Ｈ型のフレーム２１の三辺でゴム袋体２３を固定すれば、ゴム袋体２３がより強固にフレーム２１と一体化される。 For example, as shown in FIG. 4 (a), the frame 21 is H-shaped, one protruding end 21a, 21a side is hinged to the fixed block 3, and the other protruding ends 21b, 21b and the central portion 24 are U-shaped. It can be set as the rubber bag body parts 26 and 27 which fix the rubber bag body 23 on three sides between the fixed plates 22 in a shape. The rubber bag body 23 in this case is formed by welding three sides fixed to the frame 21 in the bag-like rubber sheet 20 as shown in FIG.
Thus, if the rubber bag body 23 is fixed on the three sides of the H-shaped frame 21, the rubber bag body 23 is more firmly integrated with the frame 21.

他にも、固定ブロック３の材質は、必ずしも鋼製である必要はなく、従来から存在する樹脂製のものに比べ、低い安全率で特殊な形状の固定ブロック３であっても、強度が高く、安価に製作可能なものであれば、適宜変更可能である。   In addition, the material of the fixed block 3 does not necessarily need to be made of steel, and the strength of the fixed block 3 having a low safety factor and a special shape is higher than that of a conventional resin. As long as it can be manufactured inexpensively, it can be changed as appropriate.

また、ゴム袋体部の数は、図１や図３に示すように、必ずしも２つである必要はなく、さらに増やしても良く、ゴム袋体部の膨張・収縮に連動して扉体が起立及び倒伏する構成であれば、減らしても良く、適宜変更可能である。   Further, the number of the rubber bag body portions is not necessarily two as shown in FIGS. 1 and 3, and may be further increased. The door body is linked to the expansion / contraction of the rubber bag body portion. If it is the structure which stands and falls, it may reduce and can change suitably.

加えて、固定ブロックにおいて、扉体を連結するヒンジと、ゴム袋体部のフレームを連結するヒンジとを一つのピンで結合する等、適宜変更可能である。
逆に、複数のゴム袋体部の連結部は一つのピンで軸着しているが、夫々別の位置で軸着しても良く、適宜変更可能である。 In addition, in the fixed block, the hinge for connecting the door body and the hinge for connecting the frame of the rubber bag body portion can be appropriately changed by combining them with one pin.
On the contrary, the connecting portions of the plurality of rubber bag body portions are axially attached by one pin, but may be axially attached at different positions, and can be changed as appropriate.
