Description

この発明は、水道用メータとその設置に必要となる一次側止水弁や二次側逆止弁等の各種器機を予めボックス内に組み込んだ水道用メータボックスユニットに関するものである。   The present invention relates to a water meter box unit in which various devices such as a primary side water stop valve and a secondary side check valve necessary for the water meter are installed in a box in advance.

従来、水道用メータの設置においては、メータボックス、水道用メータ、止水栓、さらには逆止弁等の各種器機が単独で現場に持ち込まれ、それぞれを順を追って個別に接続する工法が採られていた。このため、施工時間がかかり、配管品質も不均一になりやすく、さらに漏水等の不具合が発生するといった課題もあった。また、水道用メータは計量法に基づき定期的に交換する必要があるが、その付け替えの際、一旦配管上に設置されたメータを取り外すと前後の配管に軸ズレが生じ、再接続作業時に芯出しが非常に困難な場合もあって、作業の安定性が確保できないという課題もある。   Conventionally, when installing water meters, various equipment such as meter boxes, water meters, water stopcocks, and check valves have been brought to the site independently and connected individually in sequence. It was done. For this reason, the construction time is long, the pipe quality is likely to be non-uniform, and problems such as water leakage occur. In addition, water meters need to be replaced periodically based on the Measurement Act. When the meter is replaced, once the meter installed on the pipe is removed, axial displacement occurs in the front and rear pipes, and the core during reconnection work There are cases where it is very difficult to put out the work, and there is a problem that the stability of the work cannot be secured.

そこで、二個一組の継手を一定距離に直列保持してユニット化し、両継手間に水道用メータを取り付けるようにした所謂水道用メータユニットが案出されるに至っている（例えば、特許文献１を参照）。また、各種器機をボックス内に予め収容してなるボックスユニットも公知である（特許文献２を参照）。   Therefore, a so-called water meter unit has been devised in which a pair of joints are unitized by holding them in series at a fixed distance, and a water meter is attached between the joints (for example, Patent Document 1). reference). A box unit in which various devices are previously stored in a box is also known (see Patent Document 2).

特開２００４−２４５２６８号公報JP 2004-245268 A 特開２００２−２１１２４号公報Japanese Patent Laid-Open No. 2002-21124

上記従来技術のうち特許文献１で開示される水道用メータユニットは一方の継手を軸移動可能な可動受け部を備えた圧接継手により構成し、他方の固定継手との間に水道用メータを挟持する構成であるため、水道用メータの付け替え作業を容易に行うことができるが、これをメータボックスに収容することについては具体策が開示されていない。つまり、当該ユニットをメータボックスに収容した場合、水道用メータの取り付け時には上記可動受け部の軸移動に伴う接続応力が水道用メータを介して軸方向に作用し、メータボックスを押し広げようとする。このためメータボックスが合成樹脂製であるときは、当該ボックスが変形するおそれがある。この点、特許文献２に開示されたメータユニットによれば、水道用メータを含む配管ユニットを環状フレームで枠付けし、該環状フレームをボックス内に嵌入するように構成しているため、フレームによってボックスが補強され、上記変形をある程度回避することができる。   Of the above prior art, the water meter unit disclosed in Patent Document 1 is composed of a pressure-welded joint having a movable receiving portion capable of axial movement of one joint, and the water meter is sandwiched between the other fixed joint. Since it is the structure to perform, although the replacement | exchange operation | work of a water meter can be performed easily, the concrete measure is not disclosed about accommodating this in a meter box. That is, when the unit is accommodated in the meter box, when the water meter is attached, the connection stress accompanying the axial movement of the movable receiving portion acts in the axial direction via the water meter, and tries to expand the meter box. . For this reason, when the meter box is made of synthetic resin, the box may be deformed. In this regard, according to the meter unit disclosed in Patent Document 2, a pipe unit including a water meter is framed with an annular frame, and the annular frame is inserted into the box. The box is reinforced and the above deformation can be avoided to some extent.

しかしながら、上記環状フレームはボックス内に嵌入する必要上、板の縁をボックスの内部形状に合わせて加工する必要があり、当該加工に手間がかかると共に、ボックスの内部形状は同じではないから汎用性に欠ける。また、十分な補強性能を発揮するには、相当厚さの板を用いる必要があり、これに伴い上記加工にさらに手間がかかる。さらに、板状のフレームでは捻りに弱く、土中の地震動等によってフレームが破損するおそれもある。   However, it is necessary to fit the annular frame into the box, and it is necessary to process the edge of the plate according to the internal shape of the box. This processing takes time and the internal shape of the box is not the same. Lack. Moreover, in order to exhibit sufficient reinforcing performance, it is necessary to use a plate having a considerable thickness, and accordingly, the above processing further takes time. Furthermore, the plate-like frame is vulnerable to twisting, and the frame may be damaged by ground motion.

本発明は上述した課題を解決するためになされたもので、その目的とするところは、水道用メータの設置に必要な機器を予めボックスに収容してユニット化することによって、現場での配管接続にかかる時間や労力、施工費を大幅に短縮すると共に、施工ミスをなくして施工品質の均一化を図ることができる水道用メータボックスユニットを提供することである。また、樹脂製ボックスに収容する場合、当該ボックスの補強構造について開示することも本発明の目的の一つである。   The present invention has been made in order to solve the above-described problems, and the object of the present invention is to connect pipes on-site by storing equipment necessary for installing a water meter in a box in advance to form a unit. It is to provide a meter box unit for water supply that can significantly reduce the time, labor, and construction cost required for the construction, and can eliminate the construction mistake and make the construction quality uniform. Moreover, when it accommodates in resin-made boxes, it is also the objective of this invention to disclose the reinforcement structure of the said box.

上述した目的を達成するために本発明では、上流および下流側の接続部と、対向する二側壁それぞれに前記接続部の取付孔を設けた合成樹脂製のメータボックスと、該メータボックス内において前記接続部間に設けられ、少なくとも水道用メータを含むメータユニットと、前記メータボックスを前記接続部に対する前記水道用メータの接続応力から保護する補強構造とを備え、当該補強構造は、前記取付孔を介して前記メータボックスの外側に突出する前記接続部の先端から差し込まれ、かつ、当該突出する前記接続部にナットを締結することにより、メータボックスの上記二側壁それぞれの外側に対峙して固定する一対の補強板と、該一対の補強板間に前記メータユニットと平行して前記補強板の距離を保持可能に架橋される拘束棒とから構成する手段を用いた。 In order to achieve the above-described object, in the present invention, an upstream and a downstream connection part, a synthetic resin meter box provided with mounting holes for the connection part on each of two opposing side walls, A meter unit including at least a water meter, and a reinforcing structure that protects the meter box from a connection stress of the water meter with respect to the connecting portion, the reinforcing structure including the mounting hole; And is inserted from the tip of the connecting portion protruding to the outside of the meter box, and is fastened to the outside of the two side walls of the meter box by fastening a nut to the protruding connecting portion. a pair of reinforcing plates, and a restraining bar is retainable crosslink distance of the reinforcing plate in parallel with the meter unit to said pair of reinforcing plates Using a means of formation.

請求項２では拘束棒はメータボックスの内部において、一方、請求項３ではメータボックスの外部において、少なくとも二本一組を補強板間に架橋するという手段を用いた。   In the second aspect, the restraining rod is provided inside the meter box, and in the third aspect, outside the meter box, means for bridging at least two pairs between the reinforcing plates is used.

請求項４では、水道用メータを一方の接続部側に設けた圧接継手により着脱可能に取り付けるという手段を用いた。また、請求項５では、メータユニットは、上流側接続部に設けられる止水栓と、下流側接続部に設けられる逆止弁とをさらに含むこととした。   In Claim 4, the means of attaching a water meter so that attachment or detachment is possible by the press-contacting joint provided in the one connection part side was used. According to a fifth aspect of the present invention, the meter unit further includes a water stop cock provided at the upstream connection portion and a check valve provided at the downstream connection portion.

請求項６では、メータボックスは上記接続部を含む下部箱体と、該下部箱体と密閉可能に係合する上部箱体の上下二分割に構成するという手段を用いた。   According to a sixth aspect of the present invention, there is used a means in which the meter box is configured by dividing the lower box body including the connecting portion and the upper box body that can be hermetically engaged with the lower box body into upper and lower parts.

請求項７では、下部箱体には補強リブを設けるという手段を用いた。   In the seventh aspect, means for providing a reinforcing rib in the lower box is used.

請求項８では、上部箱体の側壁を下方に向かって広がる勾配とする一方、下部箱体の側壁を上部箱体とは逆勾配とするという手段を用いた。   In the eighth aspect of the invention, means is used in which the side wall of the upper box has a slope that spreads downward while the side wall of the lower box has a slope opposite to that of the upper box.

以上、本発明によれば水道用メータの設置に必要なメータユニットを予めメータボックスに組み込んだので、現場では接続部を上流側及び下流側配管に接続するのみで水道用メータの設置が完了し、配管接続にかかる時間や労力、施工費を大幅に短縮すると共に、施工ミスをなくして施工品質の均一化を図ることができる。また、メータボックスは合成樹脂製であるから、鋳物に比べて成型や大量生産が容易で、しかも軽量である。また、該メータボックスは拘束棒により接続部間の距離を一定に保持された補強板によって補強されているため、通水時の水圧や水道用メータの着脱時の接続応力によって変形しない。また、少なくとも二本一組の拘束棒を設けることによって、捻りにも強い構造とすることができる。特に請求項３では、水道用メータの接続構造として圧接継手を用いることで、従来の袋ナットによるネジ接合を廃し、工具レスで水道用メータの付け替えや交換を容易に行うことができる。さらに、メータボックスを上下二分割にし、下部箱体に水道用メータを含む各種器機のユニットを設けたので、接続作業時は上部箱体を外した状態で簡単に行え、当該作業後は上部箱体を係合凸部と係合凹部を合わせるのみで密閉され、ボックス内への異物の混入を簡易に防止することができる。さらにまた、下部箱体に補強リブを設けたので、ボックスの剛性がより高まり、変形や破損等を確実に防止することができる。また、下部箱体の側壁を上部箱体の側壁に対して逆勾配としたので、沈下防止板を用いることなく沈下防止機能を発揮する。   As described above, according to the present invention, since the meter unit necessary for installing the water meter is previously incorporated in the meter box, the installation of the water meter is completed only by connecting the connecting portion to the upstream side and the downstream side piping at the site. In addition to greatly shortening the time and labor required for pipe connection and construction costs, it is possible to eliminate construction mistakes and make the construction quality uniform. In addition, since the meter box is made of synthetic resin, it is easier to mold and mass-produce and is lighter than a casting. Further, since the meter box is reinforced by a reinforcing plate whose distance between the connecting portions is kept constant by a restraining rod, the meter box is not deformed by water pressure during water flow or connection stress when a water meter is attached or detached. Also, by providing at least two pairs of restraining rods, a structure that is resistant to twisting can be obtained. In particular, according to the third aspect, by using a pressure welding joint as a water meter connection structure, conventional screw joints with cap nuts can be eliminated, and replacement and replacement of the water meter can be easily performed without tools. In addition, since the meter box is divided into two parts, and a unit of various equipment including a water meter is provided in the lower box, it can be easily done with the upper box removed during connection work. The body is hermetically sealed only by aligning the engaging convex portion and the engaging concave portion, and foreign matter can be easily prevented from entering the box. Furthermore, since the reinforcing ribs are provided on the lower box, the rigidity of the box is further increased, and deformation and breakage can be reliably prevented. In addition, since the side wall of the lower box body has an inverse slope with respect to the side wall of the upper box body, the function of preventing settlement is exhibited without using a settlement prevention plate.

以下、本発明の好ましい実施の形態を添付した図面に従って説明する。図１は本発明の一実施形態に係る水道用メータボックスユニットの正面視断面図、図２は後述する上部箱体のみを断面した一部切欠側面図である。同図中、１はメータボックスの上部箱体、２はメータボックスの下部箱体を示し、両者はその合わせ口にフランジ１ａ・２ａを有し、該フランジ１ａ・２ａに設けた複数の係合凸部２ｂと係合凹部１ｂを合致させることによって密閉可能な位置決め部材として機能する。なお、本実施形態では上部箱体１の既存ボックス開口を塞ぎ、より密閉性を高めるため、半月状（半円状）の凸部２ｃ・凹部１ｃを設けている。そして、上部箱体１には上面に開閉可能な蓋３が設けられる一方、下部箱体２には水道用メータ等の器機ユニット及び補強構造を予め組み込んでいる。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front sectional view of a water meter box unit according to an embodiment of the present invention, and FIG. 2 is a partially cutaway side view in which only an upper box to be described later is sectioned. In the figure, reference numeral 1 denotes an upper box of the meter box, 2 denotes a lower box of the meter box, both of which have flanges 1a and 2a at their mating ports, and a plurality of engagements provided on the flanges 1a and 2a. It functions as a sealable positioning member by matching the convex portion 2b with the engaging concave portion 1b. In this embodiment, in order to close the existing box opening of the upper box 1 and further improve the sealing performance, a semicircular (semicircular) convex portion 2c and concave portion 1c are provided. The upper box 1 is provided with a lid 3 that can be opened and closed on the upper surface, while the lower box 2 is preinstalled with an equipment unit such as a water meter and a reinforcing structure.

即ち、下部箱体２において、４・５は対向する二側壁に設けられた接続部であって、それぞれ上流側・下流側配管と接続される。６は上流側接続部４に取り付けられた止水弁、７は止水弁６に取り付けられた圧接継手、８は下流側接続部５に取り付けられた逆止弁であり、圧接継手７と逆止弁８の間に水道用メータ９が着脱可能に取り付けられている。圧接継手７はキャップ７ａを図面において紙面手前若しくは奥に倒すように回せば、その回動運動が内部のラチェット機構７ｂによって可動受け部７ｃの軸方向のスライド運動に変換され、該可動受け部７ｃの突出量を調整することによって、これと対向して逆止弁８に設けた固定継手７ｄとの距離が調整され、水道用メータ９の脱着を行うものである。このことは、本出願人がなした特許文献１に既に開示しているので、詳細な説明は割愛する。なお、本実施形態では上流側接続部４側、即ち止水弁６の下流に圧接継手７を設けたが、下流側接続部５側に設けてもよいことはもちろんである。   That is, in the lower box 2, 4 and 5 are connecting portions provided on two opposing side walls, which are respectively connected to the upstream and downstream pipes. 6 is a water stop valve attached to the upstream connection portion 4, 7 is a pressure weld joint attached to the water stop valve 6, and 8 is a check valve attached to the downstream connection portion 5. A water meter 9 is detachably attached between the stop valves 8. If the cap 7a is rotated so that the cap 7a is tilted forward or backward in the drawing in the drawing, its rotational movement is converted into an axial sliding movement of the movable receiving portion 7c by the internal ratchet mechanism 7b, and the movable receiving portion 7c. By adjusting the amount of protrusion of the water meter 9, the distance from the fixed joint 7 d provided on the check valve 8 is adjusted so as to be opposed thereto, and the water meter 9 is attached and detached. Since this has already been disclosed in Patent Document 1 made by the present applicant, a detailed description thereof will be omitted. In this embodiment, the pressure connection joint 7 is provided on the upstream connection portion 4 side, that is, on the downstream side of the water stop valve 6. However, it is needless to say that the pressure connection joint 7 may be provided on the downstream connection portion 5 side.

次に、下部箱体２の補強構造として、図２および図３に示すように、メータボックスの下部箱体２の接続部４・５を設けた二側壁の外側に横長の金属製補強板１０・１１が対峙するように固定され、該補強板１０・１１間には金属製の拘束棒１２・１３が架橋されている。より詳しくは、図４に示すように、下部箱体２において接続部４・５を設けた対向する二側壁、即ち圧接継手７による接続応力や水圧がかかる方向に対向する二側壁には、中央に接続部４・５の取付孔２ｄが形成されると共に、同じ中心線上に位置して取付孔２ｄの左右に拘束棒１２・１３のボルト孔２ｅが形成されている。このような下部箱体２の構成において補強板１０・１１は、前記取付孔２ｄに取り付けた接続部４・５にメータボックスの外側において抜脱不能に差し込まれると共に、接続部４・５を間に挟んだ状態で拘束棒１２・１３が差し込まれる。次いで、下部箱体２の外側において補強板１０・１１から突出した接続部４・５および拘束棒１２・１３の先端をナット１４・１５で締付固定することによって（図５をも合わせて参照）、下部箱体２に対して接続部４・５、補強板１０・１１並びに拘束棒１２・１３の組み込みを行う。この組み込み後に、各接続部４・５に対して止水弁６、圧接継手７及び逆止弁８を取り付けることができる。   Next, as a reinforcing structure of the lower box 2, as shown in FIGS. 2 and 3, a horizontally long metal reinforcing plate 10 is provided outside the two side walls provided with the connecting portions 4 and 5 of the lower box 2 of the meter box. 11 is fixed so as to oppose, and metal restraining rods 12 and 13 are bridged between the reinforcing plates 10 and 11. More specifically, as shown in FIG. 4, the two opposite side walls provided with the connecting portions 4 and 5 in the lower box body 2, that is, the two side walls opposed in the direction in which the connection stress or water pressure is applied by the pressure welding joint 7, The connection holes 4 and 5 are formed with mounting holes 2d, and the bolt holes 2e of the restraining rods 12 and 13 are formed on the left and right of the mounting hole 2d on the same center line. In such a configuration of the lower box body 2, the reinforcing plates 10 and 11 are inserted into the connection portions 4 and 5 attached to the attachment hole 2d so as not to be removable outside the meter box, and the connection portions 4 and 5 are interposed between them. The restraining rods 12 and 13 are inserted while being sandwiched between the two. Next, by tightening and fixing the ends of the connecting portions 4 and 5 and the restraining rods 12 and 13 protruding from the reinforcing plates 10 and 11 on the outside of the lower box 2 with nuts 14 and 15 (see also FIG. 5) ) The connecting portions 4 and 5, the reinforcing plates 10 and 11, and the restraining rods 12 and 13 are assembled into the lower box 2. After this integration, the water stop valve 6, the pressure joint 7 and the check valve 8 can be attached to each of the connecting portions 4 and 5.

このように下部箱体２に補強構造と共に各種器機を予め組み込むことによって、現場での配管作業は接続部４・５のみとなり、施工にかかる時間、労力、費用を大幅に低減させることができると共に、拘束棒１２・１３によって距離が保たれた補強板１０・１１により水道用メータ９の取り付け時に発生する圧接継手７の接続応力やメータ設置後の通水時に発生する水圧等から下部箱体２が保護され、変形や破損を防止することができる。さらに、本実施形態では、上述のように接続部４・５の取付孔２ｄと拘束棒１２・１３のボルト孔２ｅを同じ中心線上に位置するように形成することによって、補強板１０・１１と拘束棒１２・１３を水道用メータ９等の配管と同一平面内に位置させたので、応力に対する強度がより向上する。また、図５に表れる下部箱体２の外周に設けた多数のリブ１６によっても下部箱体２は補強されている。この補強リブ１６は下部箱体２の内部に設けることも可能であるし、上部箱体１についても適宜設けることが好ましいことはもちろんである。   In this way, by incorporating various devices together with the reinforcing structure in the lower box 2, the piping work at the site is only the connecting parts 4 and 5, and the time, labor, and cost required for construction can be greatly reduced. The lower box 2 from the connection stress of the pressure joint 7 generated when the water meter 9 is attached by the reinforcing plates 10 and 11 maintained at a distance by the restraining rods 12 and 13 and the water pressure generated when water is passed after the meter is installed. Is protected, and deformation and breakage can be prevented. Further, in the present embodiment, the reinforcing plates 10 and 11 are formed by forming the mounting holes 2d of the connecting portions 4 and 5 and the bolt holes 2e of the restraining rods 12 and 13 on the same center line as described above. Since the restraining rods 12 and 13 are positioned in the same plane as the pipe of the water meter 9 or the like, the strength against stress is further improved. Further, the lower box 2 is also reinforced by a large number of ribs 16 provided on the outer periphery of the lower box 2 shown in FIG. Of course, the reinforcing ribs 16 can be provided inside the lower box 2, and the upper box 1 is preferably provided as appropriate.

なお、上記実施形態では拘束棒１２・１３をメータボックスの内部において架橋したが、図４において２ｅ’として示すように、そのボルト孔２ｅ’をメータボックスの外側に設けることによって、拘束棒１２・１３をメータボックスの外側に位置するように架橋してもよい。こうすることによって、メータボックス内部での煩雑な配置構成がなくなり、ボックス内の清掃やメンテナンス等が行いやすくなるという利点がある。この場合、接続部４・５の取付孔２ｄの位置を下げて、拘束棒１２・１３のボルト孔２ｅ’と中心を同じラインとして、接続部４・５、メータユニット、拘束棒１２・１３の軸線を上記実施形態のように同一平面上に位置させることが好ましいが、これに構成を限定する必要はない。このことは上記実施形態のように拘束棒１２・１３をメータボックス内で架橋した場合についても同様である。さらに補強板１０・１１の厚さ等や拘束棒１２・１３の太さや本数等は、所望する強度に応じて適宜変更することができる。この点、上記実施形態では、水道用メータ９の脱着構造として圧接継手７を採用したため、その接続応力に耐えうるものとする必要があるが、例えば、袋ナットによるネジ接合構造を採用した場合は、上記接続応力は配管そのもので吸収されるため、圧接継手７を採用した場合よりも補強板１０・１１や拘束棒１２・１３は低強度のものを採用することができる。 In the above embodiment, the restraining rods 12 and 13 are bridged inside the meter box. However, as shown by 2e 'in FIG. 4, by providing the bolt hole 2e' outside the meter box, the restraining rods 12 and 13 are provided. You may bridge | crosslink 13 so that it may be located outside a meter box. By doing so, there is an advantage that a complicated arrangement configuration inside the meter box is eliminated, and cleaning, maintenance, and the like in the box are facilitated. In this case, the positions of the mounting holes 2d of the connecting portions 4 and 5 are lowered so that the bolt holes 2e 'of the restraining rods 12 and 13 are centered on the same line, and the connecting portions 4 and 5, the meter unit, and the restraining rods 12 and 13 are connected. Although it is preferable to position the axis on the same plane as in the above embodiment, the configuration need not be limited to this. The same applies to the case where the restraining rods 12 and 13 are bridged in the meter box as in the above embodiment. Further, the thickness and the like of the reinforcing plates 10 and 11 and the thickness and number of the restraining rods 12 and 13 can be appropriately changed according to the desired strength. In this regard, in the above embodiment, since the pressure joint 7 is employed as the detachable structure of the water meter 9, it is necessary to be able to withstand the connection stress. For example, when a screw joint structure using a cap nut is employed. Since the connection stress is absorbed by the pipe itself, the reinforcing plates 10 and 11 and the restraining rods 12 and 13 can be of lower strength than when the press-fit joint 7 is used.
