Description

本発明は、鋼製の矩形の配水池に関する。   The present invention relates to a rectangular distribution reservoir made of steel.

配水池は浄水場から送り出された水を一時的に貯めておく施設で、配水量の時間変動を調整する機能を持つと共に、異常時には、断水の影響をなくす役割を果たしている。配水池としては、円筒状の貯水槽や矩形の貯水槽が適用され、鋼製の壁板材が多数接合されて構築されることが多い。   The distribution reservoir is a facility that temporarily stores the water sent from the water treatment plant, and has the function of adjusting the time fluctuation of the water distribution amount. As the distribution reservoir, a cylindrical water tank or a rectangular water tank is applied, and it is often constructed by joining a number of steel wall plates.

鋼製の壁板材を用いた配水池として、円弧状水平断面を持つ壁板材の両端部に水平断面がＴ字状のフランジ面を有する（板材の面に直交するフランジ面を有する）板材を設け、フランジ面同士を連結して側板ユニットが作製されるものが知られている（例えば、特許文献１参照）。   As a distribution reservoir using a steel wall plate material, a plate material having a flange surface having a T-shaped horizontal cross section (having a flange surface orthogonal to the surface of the plate material) is provided at both ends of the wall plate material having an arc-shaped horizontal cross section. In addition, one in which side plate units are manufactured by connecting flange surfaces to each other is known (for example, see Patent Document 1).

特許文献１に記載された従来の技術では、壁板材の円弧状水平断面により水平方向が補強され、板材のＴ字状のフランジ面により鉛直方向が補強されている。このため、水圧による荷重を的確に受けることができる側壁を備えた配水池とすることができる。   In the prior art described in Patent Document 1, the horizontal direction is reinforced by the arc-shaped horizontal section of the wall plate material, and the vertical direction is reinforced by the T-shaped flange surface of the plate material. For this reason, it can be set as the distribution reservoir provided with the side wall which can receive the load by water pressure exactly.

特許文献１に記載された従来の技術では、フランジ面同士を溶接する等して接合しているので、接合強度には限界があるのが現状である。このため、端部に板材を備えた壁板材に応力が集中することがなくなる反面、フランジ面同士の連結部位（溶接等）の強度により、側壁ユニット全体としては、水圧に対する耐圧性能が制約されていた。   In the conventional technique described in Patent Document 1, since the flange surfaces are joined together by welding or the like, the present situation is that the joining strength is limited. For this reason, stress does not concentrate on the wall plate material provided with the plate material at the end, but the pressure resistance performance against water pressure is restricted as a whole side wall unit due to the strength of the connecting portion (welding etc.) of the flange surfaces. It was.

In addition, a large number of beam members are provided in the vertical and horizontal directions inside the water storage tank, and the ends of the beam members extending in the horizontal direction are fixed to support members (described later) of the joining block member 2. Yes.

図３から図５に基づいて接合ブロック材２、及び、接合ブロック材２が連結された側壁の構成を具体的に説明する。   Based on FIGS. 3-5, the structure of the side wall to which the joining block material 2 and the joining block material 2 were connected is demonstrated concretely.

図３には壁板材、及び、支柱部材を説明するための接合ブロック材の分解斜視、図４には接合ブロック材を連結した状態の斜視、図５には壁板材の支柱部材への溶接部を説明するための図４中のＶ―Ｖ線矢視を示してある。   3 is an exploded perspective view of the joining block material for explaining the wall plate material and the column member, FIG. 4 is a perspective view in a state where the joining block material is connected, and FIG. 5 is a welded portion of the wall plate material to the column member FIG. 4 is a view taken along the line VV in FIG.

図３、図４に示すように、接合ブロック材２は、例えば、ステンレス製の複数枚（図示例では２枚）の壁板材１１を備え、２枚の壁板材１１が、例えば、ステンレス製の四角筒の支柱部材１２に接合されることで形成されている。壁板材１１は、円筒面の一部が鉛直に延びて水平断面が円弧形状とされる矩形状の壁板１５を有している。壁板１５は円弧形状の内側（膨らむ方向の反対面）が貯水槽の内面とされる。   As shown in FIGS. 3 and 4, the joining block member 2 includes, for example, a plurality of (two in the illustrated example) wall plate members 11 made of stainless steel, and the two wall plate members 11 are made of, for example, stainless steel. It is formed by being joined to a support member 12 of a square tube. The wall plate material 11 has a rectangular wall plate 15 in which a part of a cylindrical surface extends vertically and a horizontal cross section has an arc shape. The wall plate 15 has an arcuate inner side (a surface opposite to the inflating direction) as an inner surface of the water storage tank.

壁板１５の幅方向の縁部には平面フランジ部１６が連続して形成され、平面フランジ部１６は鉛直方向に延びて配されている。接合ブロック材２は、平面フランジ部１６が幅方向に隣接するように壁板材１１が配され、隣接する壁板材１１の平面フランジ部１６にわたり、支柱部材１２が貯水槽の外側（壁板１５の円弧が膨らんでいる側の外面側）に配されている。   A flat flange portion 16 is continuously formed at the edge of the wall plate 15 in the width direction, and the flat flange portion 16 extends in the vertical direction. In the joining block member 2, the wall plate material 11 is arranged so that the flat flange portion 16 is adjacent in the width direction. It is arranged on the outer surface side of the side where the arc swells.

図５に示すように、支柱部材１２の一面に平面フランジ部１６が面接合され、隣接する前記平面フランジ部の間の鉛直方向に延びる隙間Ｓが形成されている。隙間Ｓの部位が溶接を行う母材間の溝（開先）とされ、支柱部材１２の一面と一対の平面フランジ部１６を溶接することで、支柱部材１２の一面が裏当とされて開先溶接された状態になる。そして、壁板１５の円弧が膨らんでいる側の面（表側面）と支柱部材１２とは隅肉溶接により接合されている。   As shown in FIG. 5, the planar flange portion 16 is surface-bonded to one surface of the column member 12, and a gap S extending in the vertical direction between the adjacent planar flange portions is formed. The portion of the gap S is a groove (groove) between the base materials to be welded, and by welding one surface of the column member 12 and the pair of flat flange portions 16, one surface of the column member 12 is backed and opened. It will be in a pre-welded state. And the surface (front side surface) by which the circular arc of the wall board 15 is expanded, and the support | pillar member 12 are joined by fillet welding.

接合ブロック材２の壁板１５は、円筒面の一部が鉛直に延びて水平断面が円弧形状とされているので、内側からの荷重に対して応力集中が抑制された状態で支柱部材１２に固定される。このため、水圧に対する応力集中を緩和することができる。そして、壁板材１１は、表側面が隅肉溶接により支柱部材１２に固定され、平面フランジ部１６が支柱部材１２に溶接されることにより、支柱部材１２の表面が裏当て材となると共に平面フランジ部１６の隙間が開先となって開先溶接され、十分な接合強度で溶接される。   Since the wall plate 15 of the joining block member 2 has a part of the cylindrical surface extending vertically and the horizontal cross section being an arc shape, the wall plate 15 is attached to the column member 12 in a state where stress concentration is suppressed with respect to the load from the inside. Fixed. For this reason, the stress concentration with respect to the water pressure can be relaxed. And the wall board material 11 is fixed to the support | pillar member 12 by the fillet welding of the front side surface, and the plane flange part 16 is welded to the support | pillar member 12, The surface of the support | pillar member 12 becomes a backing material, and a plane flange The gap of the part 16 becomes a groove, and is welded with a sufficient joint strength.

このため、接合ブロック材２を連結して配水池１の側壁３を構築することで、水圧に対する応力集中が抑制される壁板材１１が備えられ、高い接合強度で壁板材１１が接合され、耐圧性能が保たれた状態で側壁３が構築された鋼製の矩形の貯水槽からなる配水池１となる。   For this reason, the wall board material 11 by which the stress concentration with respect to a water pressure is suppressed is provided by connecting the joining block material 2 and constructing the side wall 3 of the reservoir 1, the wall board material 11 is joined with high joint strength, The distribution reservoir 1 is formed of a steel rectangular water tank in which the side wall 3 is constructed in a state where the performance is maintained.

図６、図７に基づいて接合ブロック材２による側壁３の構築について説明する。   The construction of the side wall 3 by the joining block material 2 will be described with reference to FIGS.

図６には接合ブロック材により側壁が構成される状態を示してあり、図６（ａ）は水平方向に連結された状態（鉛直方向には分解されている状態）、図６（ｂ）は水平方向及び鉛直方向に連結されて側壁が形成された状態である。また、図７には支柱部材の嵌合部を説明する外観を示してある。   FIG. 6 shows a state in which the side wall is constituted by the joining block material. FIG. 6 (a) is a state where the side walls are connected in the horizontal direction (a state where the side wall is disassembled in the vertical direction), and FIG. The side wall is formed by being connected in the horizontal direction and the vertical direction. Moreover, the external appearance explaining the fitting part of a support | pillar member is shown in FIG.

図６に示すように、支柱部材１２を介して接合ブロック材２（壁板材１１、支柱部材１２）を接合（開先溶接）すると共に、壁板材１１の表側面を支柱部材１２に隅肉溶接することにより、例えば、壁板材１１を水平方向に４枚備えたブロックが構築される。ブロック同士を鉛直方向で接合することで、例えば、壁板材１１を８枚備えた側壁ブロックが構築される。側壁ブロック同士を適宜接合することにより、所望の形状の矩形の鋼製の貯水槽からなる配水池１とすることができる。   As shown in FIG. 6, the joining block material 2 (wall plate material 11, support member 12) is joined (groove welding) through the support member 12, and the front side surface of the wall plate material 11 is fillet welded to the support member 12. By doing so, for example, a block having four wall plates 11 in the horizontal direction is constructed. By joining the blocks in the vertical direction, for example, a side wall block including eight wall plate members 11 is constructed. By appropriately joining the side wall blocks, it is possible to obtain a distribution reservoir 1 composed of a rectangular steel water tank having a desired shape.

図７に示すように、支柱部材１２は四角筒で構成され、上端部には、一回り小さな四角筒部２１が設けられている。また、下端部には、継ぎ目部位の溶接時の裏当て材となる継ぎ板２２が設けられている。ブロック同士を鉛直方向で接合する際には、上側のブロックの支柱部材１２の筒内に上側のブロックの支柱部材１２の四角筒部２１を嵌合する（嵌合部）。   As shown in FIG. 7, the support | pillar member 12 is comprised by the square cylinder, and the square cylinder part 21 small once is provided in the upper end part. Further, a joint plate 22 serving as a backing material at the time of welding the joint portion is provided at the lower end portion. When joining the blocks in the vertical direction, the rectangular tube portion 21 of the support member 12 of the upper block is fitted into the cylinder of the support member 12 of the upper block (fitting portion).

このため、ブロック同士の鉛直方向の接合が嵌合部で案内されることになり、作業性を向上させることができる。また、継ぎ板２２が継ぎ目の部位に存在することになり、四角筒の表面の裏当て材の働きを連続させることができる。   For this reason, joining of the blocks in the vertical direction is guided by the fitting portion, and workability can be improved. Further, the joint plate 22 is present at the joint portion, and the function of the backing material on the surface of the square tube can be continued.

図８、図９に基づいてコンクリート基礎に対する底板の固定状況を説明する。   Based on FIG. 8, FIG. 9, the fixing condition of the baseplate with respect to a concrete foundation is demonstrated.

図８には底板が備えられた接合ブロック材の外観、図９には底板の固定状態を説明する断面を示してある。   FIG. 8 shows an outer appearance of the joining block member provided with the bottom plate, and FIG. 9 shows a cross section for explaining the fixed state of the bottom plate.

図８に示すように、最下段に適用される接合ブロック材２の下面には底板２５が設けられている。一方、図９に示すように、配水池１が設置されるコンクリートの基礎３１には支持アンカー３２が固定され、支持アンカー３２の上端にナット３３を介して底板２５が固定されている。支持アンカー３２に底板２５が固定されることにより、底板２５の浮き上がりが防止された状態で接合ブロック材２が基礎３１に固定設置される。   As shown in FIG. 8, a bottom plate 25 is provided on the lower surface of the joining block material 2 applied to the lowermost stage. On the other hand, as shown in FIG. 9, a support anchor 32 is fixed to the concrete foundation 31 on which the reservoir 1 is installed, and a bottom plate 25 is fixed to the upper end of the support anchor 32 via a nut 33. By fixing the bottom plate 25 to the support anchor 32, the joining block member 2 is fixedly installed on the foundation 31 in a state where the bottom plate 25 is prevented from being lifted.

底面には多数の底板が互いに溶接により接合されて備えられている。
図は省略してあるが、多数の底板の接合部位に支持アンカーを介して支持枠が固定されている。そして、支持枠の上面で底板同士が開先溶接されて連続する底板がコンクリート基礎の上に固定されている。溶接部での浮き上がりが防止されている。 A large number of bottom plates are joined to each other by welding on the bottom surface.
Although not shown in the figure, a support frame is fixed to joint portions of a large number of bottom plates via support anchors. Then, the bottom plates are groove-welded to each other on the upper surface of the support frame, and the continuous bottom plate is fixed on the concrete foundation. Lifting at the weld is prevented.

上述した鋼製の矩形の配水池１は、接合ブロック材２の壁板１５が円弧形状とされているので、内側からの荷重に対して応力集中を抑えることができる。そして、壁板材１１は、支柱部材１２に平面フランジ部１６が溶接されることにより、支柱部材１２の表面が裏当て材となると共に平面フランジ部１６の隙間が開先となって開先溶接され、壁板材１１同士が十分な接合強度で溶接される。   In the steel rectangular reservoir 1 described above, the wall plate 15 of the joining block member 2 has an arc shape, so that stress concentration can be suppressed against a load from the inside. The wall plate member 11 is groove-welded by welding the flat flange portion 16 to the column member 12 so that the surface of the column member 12 becomes a backing material and the gap of the plane flange portion 16 is a groove. The wall plate members 11 are welded with sufficient joint strength.

このため、接合ブロック材２を連結して配水池１の側壁３を構築することで、水圧に対する応力集中を緩和することができると共に、高い接合強度で壁板材１１が接合され、耐圧性能が保たれた状態で側壁３が構築された鋼製の矩形の配水池１となる。   For this reason, by connecting the joining block material 2 and constructing the side wall 3 of the reservoir 1, stress concentration against water pressure can be reduced, and the wall plate material 11 is joined with high joining strength, and the pressure resistance performance is maintained. It becomes the rectangular distribution reservoir 1 made of steel in which the side wall 3 is constructed in a leaned state.

本発明は、鋼製の矩形の配水池の産業分野で利用することができる。   INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of rectangular steel reservoirs.
