As shown in FIG. 2, the downstream mounting member 2 is mounted so as to be orthogonal to a rectangular plate-shaped fixing portion 21 fixed to the side surface 12 of the square tube and an upstream end portion of the fixing portion 21. A rectangular plate-shaped protrusion 22 is provided, and these are formed in an L shape in a plan view. Further, two reinforcing members 23 are attached to the downstream side attachment member 2 in the vertical direction.

Further, as will be described later, a downstream haunch mounting member 201 in which the lower end of the protruding portion 22 is obliquely cut off is prepared for the haunch. Further, a downstream deformed mounting member 202 connected to the lower end of the downstream haunch mounting member 201 is also prepared. The upper end of the protruding portion 22 of the downstream deformed mounting member 202 is cut off diagonally.

上流側取付部材３は、下流側取付部材２と対称な形状に形成されており、下流側取付部材２と同様に、固定部３１、突出部３２、補強材３３、及び取付孔３１１を有している。すなわち、固定部３１の下流側の端部に、突出部３２が貯鉱するように連結され、固定部３１と突出部３２とに補強材３３が固定されている。 The upstream side mounting member 3 is formed in a shape symmetrical to the downstream side mounting member 2, and has a fixing portion 31, a protruding portion 32, a reinforcing member 33, and a mounting hole 311 like the downstream side mounting member 2. ing. That is, the projecting portion 32 is connected to the downstream end of the fixing portion 31 so as to store ore, and the reinforcing member 33 is fixed to the fixing portion 31 and the projecting portion 32.

なお、上流側取付部材３も、下流側取付部材２と同様に、取り付けられる箇所の要求に応じて、上下方向の長さ、補強材３３の数、取付孔３１１の数を適宜変更することができる。また、後述するように、ハンチ用に突出部３２の下端部が斜めに切り取られた上流側ハンチ用取付部材３０１が準備される。また、この上流側ハンチ用取付部材３０１の下端に連結される上流側変形取付部材３０２も準備される。この上流側変形取付部材３０２は、突出部３２の上端部が斜めに切り取られている。 As with the downstream mounting member 2, the upstream mounting member 3 may be appropriately changed in length in the vertical direction, the number of reinforcing members 33, and the number of mounting holes 311 according to the request of the mounting location. can. Further, as will be described later, an upstream side haunch mounting member 301 whose lower end portion of the protruding portion 32 is obliquely cut off is prepared for the haunch. Further, an upstream side deformation mounting member 302 connected to the lower end of the upstream side haunch mounting member 301 is also prepared. The upper end of the protruding portion 32 of the upstream deformed mounting member 302 is cut off diagonally.

このように形成された下流側取付部材２と上流側取付部材３は、図３に示すように、固定部２１，３１の取付孔２１１，３１１に挿通されたアンカーボルト４によって、角管の側面１２に固定される。また、下流側取付部材２の突出部２２と、上流側取付部材３の突出部３２とが所定間隔をおいて配置され、これらの間に次に説明する閉鎖板５、６０１〜６１１，７が嵌め込まれる。 As shown in FIG. 3, the downstream side mounting member 2 and the upstream side mounting member 3 formed in this way are formed on the side surface of the square tube by the anchor bolts 4 inserted into the mounting holes 211 and 311 of the fixing portions 21 and 31. It is fixed at 12. Further, the protruding portion 22 of the downstream mounting member 2 and the protruding portion 32 of the upstream mounting member 3 are arranged at predetermined intervals, and the closing plates 5, 601-611, 7 described below are arranged between them. It is fitted.

＜３．閉鎖板＞
本実施形態においては、一例として、３種類の閉鎖板が用いられる。すなわち、１個の下段閉鎖板５と、１１個の中段閉鎖板６０１〜６１１と、１個の上段閉鎖板７とが用いられる。図４に示すように、下段閉鎖板５は、角管の底面１１に接するように配置されるものであり、底面１１に沿うように、下端部が下に凸となるように湾曲している。下段閉鎖板５には、水平方向に所定間隔を空けてＵ字状の把手５１が２個取り付けられている。また、上流側の面の両端部には、帯状の止水ゴム５２がそれぞれ取り付けられている。一方、下流側の面の両端部には、両端にいくにしたがって下段閉鎖板５からの突出高さが低くなる楔部材５３がそれぞれ取り付けられている。 <3. Closing plate>
In this embodiment, as an example, three types of closing plates are used. That is, one lower closing plate 5, 11 middle closing plates 601-611, and one upper closing plate 7 are used. As shown in FIG. 4, the lower closing plate 5 is arranged so as to be in contact with the bottom surface 11 of the square tube, and is curved so that the lower end portion is convex downward along the bottom surface 11. .. Two U-shaped handles 51 are attached to the lower closing plate 5 at predetermined intervals in the horizontal direction. Further, strip-shaped waterproof rubbers 52 are attached to both ends of the upstream surface. On the other hand, wedge members 53 are attached to both ends of the surface on the downstream side so that the height of protrusion from the lower closing plate 5 decreases toward both ends.

この下段閉鎖板５は、図７に示すように、下流側取付部材２と上流側取付部材３との間に固定される。すなわち、下段閉鎖板５の止水ゴム５２が、上流側取付部材３の突出部３２の下流側の面（平面）に接し、止水効果を高める。また、下段閉鎖板５の楔部材５３は、下段閉鎖板５と下流側取付部材２の突出部２２の上流側の面（平面）との隙間に嵌め込まれる。そのため、楔効果によって下段閉鎖板５を、両取付部材２，３の間に強固に固定する。なお、以上の固定の仕組みは、中段閉鎖板６０１〜６１１、及び上段閉鎖板７においても同じである。 As shown in FIG. 7, the lower closing plate 5 is fixed between the downstream mounting member 2 and the upstream mounting member 3. That is, the water blocking rubber 52 of the lower closing plate 5 comes into contact with the downstream surface (flat surface) of the protruding portion 32 of the upstream mounting member 3 to enhance the water stopping effect. Further, the wedge member 53 of the lower closing plate 5 is fitted into the gap between the lower closing plate 5 and the upstream surface (planar surface) of the protruding portion 22 of the downstream mounting member 2. Therefore, the lower closing plate 5 is firmly fixed between the mounting members 2 and 3 by the wedge effect. The above fixing mechanism is the same for the middle-stage closing plates 601 to 611 and the upper-stage closing plates 7.

図５に示すように、中段閉鎖板６０１〜６１１は、平面視矩形状に形成され、下段閉鎖板５と同様に、２個の把手６１が取り付けられている。また、上流側の面の両端部には、下段閉鎖板５と同様の帯状の止水ゴム６２がそれぞれ取り付けられ、下流側の面の両端部には、下段閉鎖板５と同様の楔部材６３がそれぞれ取り付けられている。また、以下では、説明の便宜のため、下方から上方に向かって積み重ねられる中段閉鎖板をそれぞれ、第１〜第１１中段閉鎖板６０１〜６０２と称することとする。 As shown in FIG. 5, the middle-stage closing plates 601 to 611 are formed in a rectangular shape in a plan view, and two handles 61 are attached like the lower-stage closing plate 5. Further, strip-shaped waterproof rubbers 62 similar to the lower closing plate 5 are attached to both ends of the upstream surface, and wedge members 63 similar to the lower closing plate 5 are attached to both ends of the downstream surface. Are attached to each. Further, in the following, for convenience of explanation, the middle-stage closing plates stacked from the bottom to the top will be referred to as the first to eleventh middle-stage closing plates 601-602, respectively.

図６に示すように、上段閉鎖板７は、最上段に取り付けられ、平面視五角形に形成されている。すなわち、角管のハンチ１４１を含む上面１４と対応するように、上辺の両端に斜めに傾斜する角部７５が形成されている。また、上段閉鎖板７は、平面視矩形状に形成され、下段閉鎖板５と同様に、２個の把手７１が取り付けられている。また、上流側の面の両端部には、下段閉鎖板５と同様の帯状の止水ゴム７２がそれぞれ取り付けられ、下流側の面の両端部には、下段閉鎖板５と同様の楔部材７３がそれぞれ取り付けられている。但し、止水ゴム７２は、斜めに延びる角部７５に沿って斜めに延びるように形成されている。 As shown in FIG. 6, the upper closing plate 7 is attached to the uppermost stage and is formed in a pentagonal shape in a plan view. That is, diagonally inclined corner portions 75 are formed at both ends of the upper side so as to correspond to the upper surface 14 including the haunch 141 of the square tube. Further, the upper closing plate 7 is formed in a rectangular shape in a plan view, and two handles 71 are attached like the lower closing plate 5. Further, strip-shaped waterproof rubbers 72 similar to the lower closing plate 5 are attached to both ends of the upstream surface, and wedge members 73 similar to the lower closing plate 5 are attached to both ends of the downstream surface. Are attached to each. However, the waterproof rubber 72 is formed so as to extend diagonally along the diagonally extending corner portion 75.

まず、図８に示すように、角管の両側面１２に、それぞれ上流側取付部材３を固定する。この例では、下側から、上流側取付部材３が２個固定されている。その上には上流側変形取付部材３０２が１個固定されている。この上流側変形取付部材３０２は、ハンチ１４１の下端まで延びるように取り付けられている。そして、ハンチ１４１には、上流側ハンチ用取付部材３０１が１個固定されている。上流側ハンチ用取付部材３０１の突出部の下端は斜めに延びているが、これが上流側変形取付部材３０２の突出部の上端と接している。したがって、側面１２とハンチ１４１の全長に亘って、これら上流側取付部材３，３０１，３０２により、下流側を向く平坦な壁が形成される。 First, as shown in FIG. 8, the upstream side mounting member 3 is fixed to both side surfaces 12 of the square tube. In this example, two upstream side mounting members 3 are fixed from the lower side. One upstream deformation mounting member 302 is fixed on it. The upstream deformation mounting member 302 is mounted so as to extend to the lower end of the haunch 141. Then, one upstream side haunch attachment member 301 is fixed to the haunch 141. The lower end of the protruding portion of the upstream side haunch mounting member 301 extends diagonally, and this is in contact with the upper end of the protruding portion of the upstream side deformed mounting member 302. Therefore, over the entire length of the side surface 12 and the haunch 141, these upstream mounting members 3, 301, 302 form a flat wall facing the downstream side.

以下、下流側取付部材２と閉鎖板５、６０１〜６１１，７の取付について説明するが、説明の便宜のため、図９〜図１５では、上流側取付部材３、３０１，３０２は省略している。 Hereinafter, mounting of the downstream mounting member 2 and the closing plates 5, 601-611, 7 will be described, but for convenience of explanation, the upstream mounting members 3, 301, 302 are omitted in FIGS. 9 to 15. There is.

次に、図９に示すように、両側面１２のそれぞれに、下端から延びるように、下流側取付部材２を１個ずつ固定する。これにより、下流側取付部材２と上流側取付部材との間には、下段閉鎖板５及び第１〜第３中段閉鎖板６０１〜６０３用の隙間が形成される。続いて、図１０に示すように、この隙間に下段閉鎖板５と、第１〜第３中段閉鎖板６０１〜６０３を、この順で上から嵌め込んでいく。 Next, as shown in FIG. 9, one downstream mounting member 2 is fixed to each of the side surfaces 12 so as to extend from the lower end. As a result, a gap for the lower closing plate 5 and the first to third middle closing plates 601 to 603 is formed between the downstream mounting member 2 and the upstream mounting member. Subsequently, as shown in FIG. 10, the lower closing plate 5 and the first to third middle closing plates 601-603 are fitted into the gap from above in this order.

これに続いて、図１１に示すように、先に取り付けた下流側取付部材２の上に、さらに下流側取付部材２を１個ずつ固定する。そして、固定した下流側取付部材２と上流側取付部材３との隙間に、第４〜第９中段閉鎖板６０４〜６０９を上から嵌め込んでいく。この状態で、第９中段閉鎖板６０９の上には、さらに２個の中段閉鎖板６１０，６１１と上段閉鎖板７が取り付けられる空間が残っている。 Following this, as shown in FIG. 11, the downstream side mounting member 2 is further fixed one by one on the previously mounted downstream side mounting member 2. Then, the fourth to ninth middle stage closing plates 604 to 609 are fitted from above into the gap between the fixed downstream side mounting member 2 and the upstream side mounting member 3. In this state, on the ninth middle-stage closing plate 609, there remains a space in which two more middle-stage closing plates 610 and 611 and the upper-stage closing plate 7 can be attached.

次に、図１２に示すように、各側面１２において、既に固定された下流側取付部材２の上方に３個のアンカーボルト４１〜４３を固定する。ここでは、これら３個のアンカーボルトを上から第１，第２，及び第３アンカーボルト４１，４２，４３と称することとする。まず、最上段にある第９中段閉鎖板６０９と第３アンカーボルト４３のとの上下方向の距離を、中段閉鎖板６０１〜６１１の上下方向の高さよりも小さくする。また、第２及び第３アンカーボルト４２，４３の上下方向の隙間は、中段閉鎖板６０１〜６１１の上下方向の高さよりも狭くする。そして、第１及び第２アンカーボルト４１，４２の隙間は、中段閉鎖板６０１〜６１１の上下方向の高さよりも広くする。 Next, as shown in FIG. 12, three anchor bolts 41 to 43 are fixed above the already fixed downstream side mounting member 2 on each side surface 12. Here, these three anchor bolts will be referred to as the first, second, and third anchor bolts 41, 42, and 43 from the top. First, the vertical distance between the ninth middle-stage closing plate 609 and the third anchor bolt 43 on the uppermost stage is made smaller than the vertical height of the middle-stage closing plates 601 to 611. Further, the vertical gaps between the second and third anchor bolts 42 and 43 are made narrower than the vertical heights of the middle closing plates 601 to 611. The gap between the first and second anchor bolts 41 and 42 is made wider than the height of the middle closing plates 601 to 611 in the vertical direction.

次に、図１４に示すように、第９中段閉鎖板６０９の上に、２個の中段閉鎖板６１０，６１１と上段閉鎖板７を取り付ける。まず、第１及び第２アンカーボルト４１，４２の隙間から、第１０中段閉鎖板６１０を挿入し、下方に移動させて、第９中段閉鎖板６０９の上端に載せる。第１０中段閉鎖板６１０は、第２及び第３アンカーボルト４２，４３によって支えられるため、下流側には倒れない。次に、第１１中段閉鎖板６１１を第１及び第２アンカーボルト４１，４２の隙間から挿入し、作業者が支えるなどして、上流側変形取付部材３０２に押しつける。さらに、上段閉鎖板７を第１アンカーボルト４１の上方から嵌め込み、作業者が支えるなどして、上流側ハンチ用取付部材３０１に押しつける。この状態で、下流側変形取付部材２０２を第１〜第３アンカーボルト４１〜４３に固定する。これにより、第１１中段閉鎖板６１１が、上流側変形取付部材３０２と下流側変形取付部材２０２に挟まれて固定される。 Next, as shown in FIG. 14, two middle-stage closing plates 610 and 611 and an upper-stage closing plate 7 are mounted on the ninth middle-stage closing plate 609. First, the tenth middle stage closing plate 610 is inserted through the gaps between the first and second anchor bolts 41 and 42, moved downward, and placed on the upper end of the ninth middle stage closing plate 609. Since the tenth middle stage closing plate 610 is supported by the second and third anchor bolts 42 and 43, it does not fall to the downstream side. Next, the eleventh middle stage closing plate 611 is inserted through the gaps between the first and second anchor bolts 41 and 42, and is pressed against the upstream deformed mounting member 302 by being supported by an operator or the like. Further, the upper closing plate 7 is fitted from above the first anchor bolt 41 and is supported by an operator or the like and pressed against the upstream side haunch mounting member 301. In this state, the downstream deformation mounting member 202 is fixed to the first to third anchor bolts 41 to 43. As a result, the eleventh middle stage closing plate 611 is sandwiched and fixed between the upstream side deformation mounting member 302 and the downstream side deformation mounting member 202.

最後に、図１５に示すように、ハンチ１４１にアンカーボルト４４を固定した上で、このアンカーボルト４４に下流側ハンチ用取付部材２０１を固定する。これにより、上段閉鎖板７が、上流側ハンチ用取付部材３０１と下流側ハンチ用取付部材２０１に挟まれて固定される。こうして、全ての閉鎖板５，６０１〜６１１，７が取り付けられ、角管が閉鎖される。 Finally, as shown in FIG. 15, after fixing the anchor bolt 44 to the haunch 141, the downstream side haunch mounting member 201 is fixed to the anchor bolt 44. As a result, the upper closing plate 7 is sandwiched and fixed between the upstream haunch mounting member 301 and the downstream haunch mounting member 201. In this way, all the closing plates 5,601 to 611,7 are attached and the square tube is closed.
