Description

【０００１】
【発明の属する技術分野】
本発明は、制水扉の不断水設置工法に関するものである。
【０００２】
【従来の技術】
上下水道の水路や灌漑用水路などに流路を開放或いは閉止するために設置される制水扉は、一般に図４および図７に示すように、縦溝３２，３２を有する一対の縦枠部３１，３１を形成し、双方の縦溝３２，３２が対向するように構成された戸当り３３と、この戸当り３３に前記縦溝３２，３２をガイドとして昇降自在に嵌入される扉体３４と、を備えた構造からなる。扉体３４は図示しない開閉機により昇降するようになっている。また通常、戸当り３３および扉体３４は鋳鉄（ＦＣ２００）製等である。本制水扉の場合、左右の縦枠部３１は上下の横枠部３５により連結され、これら左右の縦枠部３１と上下の横枠部３５に囲まれた部位が水を通過させる矩形状の開口部３３ａ（図５）となっている。
【０００３】
図５〜図７に示すように、左右の縦枠部３１の前面および上下の横枠部３５の前面には戸当り止水板３６が固着され、この戸当り止水板３６に対応する扉体３４の上下左右の側縁後面には扉体止水板３７が固着される。そして、戸当り３３側においては、下部側前面に、押え板４３を介して、傾斜面を有する楔型固着具３８が取り付けられ、扉体３４側においては、その両側縁の前面における前記楔型固着具３８に対応する位置に楔型部材３９が取り付けられる。この楔型部材３９と楔型固着具３８とは、扉体３４を下降させたとき相互の傾斜面が摺接し、扉体３４を後側に押し遣る。そして、扉体３４が完全に閉止したとき、扉体３４を戸当り３３に押さえ付け、前記戸当り止水板３６と扉体止水板３７とが密着して止水性を保持する。なお、符号４５は、扉体３４が下降した全閉状態時において扉体３４の底部に当接するストッパである。
【０００４】
前記戸当り３３は、その後面に注入、養生させるモルタル等の基礎Ｇに一体的に固設され、且つアンカーボルト４０およびナット４４で締結されることにより、水路を構成する壁体Ｆに対しての取り付けがなされる。アンカーボルト４０は例えば図７に示すように、補助筋４１を介して壁体Ｆの鉄筋４２に固定されるものである。一般に、コンクリート等からなる壁体Ｆは直角度等においてその精度が悪く、例えばボルト締結等で戸当り３３を壁体Ｆに直接取り付けると、開閉機との芯出しが狂い、扉体３４が昇降しなくなってしまう。そのため、戸当り３３の垂直度等の位置調整を行った後に基礎Ｇを介在させて壁体Ｆに固設するという構造になるわけである。
【０００５】
【発明が解決しようとする課題】
既設の制水扉の老朽化に伴い新規な制水扉に交換する交換工事等においては、下流側に位置する処理系の機能を停止させることのないよう、常に水路に水を流した状態（不断水）として工事を行うことが望ましい。そして、この不断水の状態で制水扉を設置する方法としては、
（１）戸当りのみを先に壁体に取り付け、扉体を後から戸当りに嵌入する。
（２）扉体を戸当りに嵌入し、扉体を開いた状態としながら戸当りを壁体に取り付ける。
等の方法が考えられる。
【０００６】
しかし、前記（１），（２）の方法のように、扉体を戸当りから外した状態、又は扉体を開いた状態として取り付け工事を行った場合には、前記制水扉の場合を例にとると、微妙な位置ずれ等に起因して扉体３４を再び下降して閉じたときには前記戸当り止水板３６と扉体止水板３７との間の止水性が悪くなるという問題がある。また、取り付け作業中にはスキミの確認や前記したストッパ４５の調整等、扉体３４の全閉状態でないとできない作業もある。そのため、従来においては、制水扉は必ず工場出荷の状態（扉体が戸当りに全閉状態として組み込まれた状態）のままで取り付けるという方法が採られており、したがって、この間、下流側に水が流れず一時的に水路が断水し、下流側の処理系の機能が停止してしまうという問題があった。
【０００７】
本発明は、このような問題を解決するために創作されたものであり、簡単な構造で、不断水状態での設置が可能となる制水扉の不断水設置工法を提供することを目的としている。
【０００８】
【課題を解決するための手段】
本発明は前記課題を解決するため、壁体に基礎を介して取り付けられる戸当りと、該戸当りに昇降自在に嵌入される扉体とを備えた制水扉において、扉体に、表裏方向に貫通する開口部を設ける構成とし、該制水扉を水路に設置するに当たり、（１）扉体を、戸当りに固着された戸当り止水板と扉体に固着された扉体止水板とを密着させた工場出荷時の全閉状態に維持したままで、前記開口部にて水を通過させながら戸当りを壁体に取り付け、（２）戸当りの所定の取り付け作業が終わった後に、蓋部材により前記開口部を閉塞することを特徴とする制水扉の不断水設置工法とした。
【００１０】
【発明の実施の形態】
本発明について図１〜図３を参照しながら説明する。本発明の制水扉Ａの基本的構成は例えば従来技術で述べた制水扉とほぼ同一であり、縦溝２，２を有する一対の縦枠部１，１を形成し、双方の縦溝２，２が対向するように構成された戸当り３と、この戸当り３に前記縦溝２，２をガイドとして昇降自在に嵌入される扉体４と、を備えた構造からなる。扉体４は上方に位置した開閉機（図示せず）によりロッド１０を介して昇降するようになっている。戸当り３および扉体４は鋳鉄（ＦＣ２００）製等である。制水扉Ａの下部においては、左右の縦枠部１，１と上下の横枠部５，５により囲まれた矩形状の開口部３ａ（請求項に記載の開口部とは異なる）が形成されており、扉体４が下降しきったときに該開口部３ａを閉じるようになっている。
【００１１】
左右の縦枠部１の前面および上下の横枠部５の前面には戸当り止水板６が固着され、この戸当り止水板６に対応する扉体４の上下左右の側縁後面には扉体止水板７が固着される。そして、戸当り３側においては、下部側前面に、押え板１１を介して、傾斜面を有する楔型固着具８が取り付けられ、扉体４側においては、その両側縁の前面における前記楔型固着具８に対応する位置に楔型部材９が取り付けられる。この楔型部材９と楔型固着具８とは、扉体４を下降させたとき相互の傾斜面が摺接し、扉体４を後側に押し遣る。そして、扉体４が完全に閉止したとき、扉体４を戸当り３に押さえ付け、前記戸当り止水板６と扉体止水板７とが密着して止水性を保持する。
【００１２】
符号１２は、扉体４が下降した全閉状態時において扉体４の底部に当接するストッパを示す。戸当り３の底部にはそれぞれ鉛直方向に沿って雌ねじ加工が施された台座１３，１３が固着されており、それぞれの雌ねじ部の縁部上面にはナット１４が固着されている。そして、それぞれのナット１４及び雌ねじ部にはボルト１５が螺合されていて、扉体４の底部はこのボルト１５の頭部に当接する。したがって、このボルト１５を適宜に回動することにより扉体４の閉止状態における高さ調整が行われる。
【００１３】
さて、扉体４には、表裏方向に貫通する開口部１６及びこの開口部１６を閉塞する蓋部材１７が設けられる。本形態において、当該開口部１６は円孔からなり、扉体４の中央に形成されている。蓋部材１７としては鋳鉄等からなる円板形状のフランジ蓋等である。蓋部材１７の取り付けとしては、例えば、扉体４側においては、開口部１６の周縁に円周方向に沿って等間隔で複数の雌ねじ部１８を螺設し、蓋部材１７側においては、この雌ねじ部１８に対応するように複数のボルト貫通孔１９を穿設し、場合によってリング状のシール部材２１を介在させて、ボルト２０により蓋部材１７を扉体４に締結固定する。
【００１４】
以上の構成からなる制水扉Ａを例えば、水路に水を流した状態において壁体Ｆに設置する場合について説明する。制水扉Ａを施工現場に搬入する段階では前記蓋部材１７は扉体４に取り付けられていない状態であり、作業者は、扉体４を全閉状態としたまま、制水扉Ａの正確な位置決め調整やスキミの確認、前記したストッパ１２の高さ調整等を行いつつ、戸当り３を壁体Ｆに取り付ける。この間、水は常に開口部１６を通過して下流側に流れることとなり、これにより扉体４を工場出荷時の全閉状態としたまま、すなわち、前記戸当り止水板６と扉体止水板７とによる止水性能を工場出荷時の状態として維持したままでの制水扉の不断水設置が実現されることとなる。なお、壁体Ｆに対する戸当り３の取り付けは、従来技術で説明したように、モルタル（水中モルタルが望ましい）等の基礎Ｇの形成やアンカーボルト（ケミカルアンカーが望ましい）を使用して行われる。
【００１５】
そして、壁体Ｆに対する戸当り３の所定の取り付け作業が終わったら、ボルト２０により蓋部材１７を扉体４に締結固定し、開口部１６を閉塞する。これにより以降、扉体４は従来の扉体と同様、本来の機能を発揮し、上昇時には水路を開放し、下降しきった状態においては水路を遮断する。
【００１６】
以上、本発明について好適な実施形態を説明したが、本発明はこれらの実施形態に限られることなく、その趣旨を逸脱しない範囲で、適宜設計変更が可能である。
【００１７】
【発明の効果】
本発明によれば、簡単な構造であって、扉体を全閉状態としたままで、つまり扉体の止水性を損ねることなく、制水扉の不断水設置を構築できる。したがって、下流側に常に水が流れ、下流側の処理系の機能が停止するという問題も解消される。

BACKGROUND OF THE INVENTION
The present invention relates to a constant water installation method for a water control door .
[0002]
[Prior art]
As shown in FIGS. 4 and 7, a water control door installed to open or close a channel in a water supply / sewerage channel or an irrigation channel generally has a pair of vertical frame portions 31 having vertical grooves 32, 32, as shown in FIGS. 31 and a door stop 33 configured such that both vertical grooves 32 and 32 face each other, and a door body 34 fitted into the door stop 33 so as to be movable up and down using the vertical grooves 32 and 32 as a guide. , Comprising the structure. The door body 34 is moved up and down by an opening / closing device (not shown). Usually, the door stop 33 and the door body 34 are made of cast iron (FC200) or the like. In the case of this water control door, the left and right vertical frame portions 31 are connected by the upper and lower horizontal frame portions 35, and the portion surrounded by the left and right vertical frame portions 31 and the upper and lower horizontal frame portions 35 allows the water to pass therethrough. The opening 33a (FIG. 5).
[0003]
As shown in FIGS. 5 to 7, door stop water plates 36 are fixed to the front surfaces of the left and right vertical frame portions 31 and the upper and lower horizontal frame portions 35, and the doors corresponding to the door stop water stop plates 36 are provided. Door body water stop plates 37 are fixed to the rear surfaces of the side edges of the body 34 in the vertical and horizontal directions. On the door stop 33 side, a wedge-shaped fixing tool 38 having an inclined surface is attached to the lower front surface via a pressing plate 43, and on the door body 34 side, the wedge shape on the front surface of both side edges thereof. A wedge-shaped member 39 is attached at a position corresponding to the fixing tool 38. When the door body 34 is lowered, the wedge-shaped member 39 and the wedge-shaped fixing tool 38 come into sliding contact with each other, and push the door body 34 rearward. When the door body 34 is completely closed, the door body 34 is pressed against the door stop 33, and the door stop water stop plate 36 and the door body water stop plate 37 are brought into close contact with each other to keep the water stop. Reference numeral 45 denotes a stopper that contacts the bottom of the door body 34 when the door body 34 is in the fully closed state.
[0004]
The door stop 33 is integrally fixed to a foundation G such as a mortar or the like to be injected and cured on the rear surface thereof, and is fastened with an anchor bolt 40 and a nut 44 so that the wall body F constituting the water channel is fixed. Is installed. For example, as shown in FIG. 7, the anchor bolt 40 is fixed to the reinforcing bar 42 of the wall body F via the auxiliary bar 41. In general, the accuracy of the wall body F made of concrete or the like is low at a right angle or the like. For example, if the door stop 33 is directly attached to the wall body F by bolt fastening or the like, the centering with the opening / closing device is out of order, and the door body 34 is raised and lowered. I will not. Therefore, after adjusting the position of the door contact 33 such as the vertical degree, the base G is interposed and the structure is fixed to the wall body F.
[0005]
[Problems to be solved by the invention]
When replacing existing water control doors with new ones, water is always flowing through the waterways so that the functions of the treatment system located downstream will not be stopped ( It is desirable to carry out construction as unrestricted water). And as a method of installing a water control door in the state of this constant water,
(1) Attach only the door stop to the wall body first, and insert the door body into the door stop later.
(2) Insert the door into the door and attach the door to the wall while keeping the door open.
Such a method is conceivable.
[0006]
However, as in the methods (1) and (2) above, when the installation work is performed with the door removed from the door or the door opened, For example, when the door body 34 is lowered and closed again due to a subtle positional shift or the like, the water stoppage between the door stop water stop plate 36 and the door body water stop plate 37 is deteriorated. There is. Further, there are some operations that can be performed only when the door body 34 is not fully closed, such as confirmation of a gap and adjustment of the stopper 45 described above, during the mounting operation. For this reason, conventionally, the water control door is always installed in the factory-shipped state (the door body is incorporated in a fully closed state per door). There was a problem that the function of the processing system on the downstream side was stopped because water did not flow and the water channel was temporarily cut off.
[0007]
The present invention was created to solve such problems, and has an object of providing a continuous water installation method for a water control door that can be installed in a continuous water state with a simple structure. Yes.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a water control door having a door stop attached to a wall body through a foundation and a door body fitted in the door door so as to be movable up and down. When the water control door is installed in the water channel, (1) the door body is a door stop water plate fixed to the door and the door body water stop fixed to the door body. The door stop was attached to the wall while allowing water to pass through the opening while maintaining the factory-closed state in close contact with the plate, and (2) the predetermined attachment work for the door was completed. Later, the opening was closed by a lid member, and the water control door was constructed with a continuous water installation method.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to FIGS. The basic structure of the water control door A of the present invention is substantially the same as, for example, the water control door described in the prior art, and a pair of vertical frame portions 1 and 1 having vertical grooves 2 and 2 are formed. The door unit 3 is configured so that the doors 2 and 2 are opposed to each other, and the door body 4 is fitted into the door unit 3 so as to be movable up and down with the longitudinal grooves 2 and 2 as a guide. The door body 4 is moved up and down via a rod 10 by an opening / closing device (not shown) positioned above. The door stop 3 and the door body 4 are made of cast iron (FC200) or the like. In the lower part of the water control door A, a rectangular opening 3a (different from the opening described in the claims) surrounded by the left and right vertical frame portions 1, 1 and the upper and lower horizontal frame portions 5, 5 is formed. The opening 3a is closed when the door 4 is lowered.
[0011]
Door stop water stop plates 6 are fixed to the front surfaces of the left and right vertical frame portions 1 and the upper and lower horizontal frame portions 5, and the door bodies 4 corresponding to the door stop water stop plates 6 are provided on the rear surfaces of the upper, lower, left and right side edges. The door body water stop plate 7 is fixed. On the door stop 3 side, a wedge-shaped fixing tool 8 having an inclined surface is attached to the lower front surface via the presser plate 11, and on the door body 4 side, the wedge shape on the front surface of both side edges thereof. A wedge-shaped member 9 is attached at a position corresponding to the fixing tool 8. When the door body 4 is lowered, the wedge-shaped member 9 and the wedge-shaped fixing tool 8 come into sliding contact with each other to push the door body 4 rearward. When the door body 4 is completely closed, the door body 4 is pressed against the door stop 3, and the door stop water stop plate 6 and the door body water stop plate 7 are brought into close contact with each other to keep the water stop.
[0012]
Reference numeral 12 denotes a stopper that contacts the bottom of the door body 4 when the door body 4 is lowered. Bases 13 and 13 that are internally threaded along the vertical direction are fixed to the bottom of the door stop 3, and nuts 14 are fixed to the upper surface of the edge of each internal thread. Bolts 15 are screwed into the nuts 14 and the female screw portions, and the bottom of the door body 4 comes into contact with the heads of the bolts 15. Therefore, the height adjustment in the closed state of the door body 4 is performed by appropriately rotating the bolt 15.
[0013]
Now, the door 4 is provided with an opening 16 penetrating in the front and back direction and a lid member 17 for closing the opening 16. In the present embodiment, the opening 16 is a circular hole and is formed at the center of the door body 4. The lid member 17 is a disc-shaped flange lid made of cast iron or the like. As for attachment of the lid member 17, for example, on the door body 4 side, a plurality of female screw portions 18 are screwed around the periphery of the opening 16 at equal intervals along the circumferential direction, and on the lid member 17 side, A plurality of bolt through holes 19 are formed so as to correspond to the female screw portion 18, and a ring-shaped seal member 21 is interposed in some cases, and the lid member 17 is fastened and fixed to the door body 4 by the bolt 20.
[0014]
The case where the water control door A which consists of the above structure is installed in the wall body F in the state which poured water into the waterway, for example is demonstrated. At the stage of bringing the water control door A into the construction site, the lid member 17 is not attached to the door body 4, and the operator keeps the door body 4 in a fully closed state, and the operator does not know the accuracy of the water control door A. The door stop 3 is attached to the wall body F while performing accurate positioning adjustment, confirmation of the gap, and the height adjustment of the stopper 12 described above. During this time, the water always passes through the opening 16 and flows downstream, so that the door body 4 remains in the fully closed state at the time of shipment from the factory, that is, the door stop water stop plate 6 and the door body water stoppage. The constant water installation of the water control door will be realized while maintaining the water stop performance by the plate 7 as the factory shipment state. Note that the attachment of the door-to-door 3 to the wall body F is performed using formation of a foundation G such as mortar (preferably underwater mortar) or an anchor bolt (preferably chemical anchor) as described in the prior art.
[0015]
Then, when the predetermined attaching operation of the door stop 3 to the wall body F is finished, the lid member 17 is fastened and fixed to the door body 4 by the bolts 20 and the opening 16 is closed. As a result, the door body 4 subsequently performs the same function as the conventional door body, opens the water channel when it rises, and blocks the water channel when it is fully lowered.
[0016]
As mentioned above, although preferred embodiment was described about this invention, this invention is not limited to these embodiment, In the range which does not deviate from the meaning, a design change is possible suitably.
[0017]
【The invention's effect】
According to this invention, it is a simple structure, Comprising: With the door body made into a fully-closed state, ie, without impairing the water stop property of a door body, the unrestricted water installation of a water control door can be constructed | assembled. Therefore, the problem that water always flows to the downstream side and the function of the downstream processing system stops is also solved.
