Description
【０００１】[0001]
本考案は、給水栓取付け前（本格的配管前）に上水道配管に仮に取付けて仮止 水し、かつ、水圧テストを行うためのプラグに関する。 The present invention relates to a plug for temporarily installing water taps to temporarily stop water before a water tap is installed (before full-scale piping) and for performing a water pressure test.
【０００２】[0002]
従来、建築物の壁を構築する前の段階で、上水道の立上げ配管が取付け工事さ れ、その配管先端に（蛇口を取付けるための）エルボ型管継手を取付けていた。 そして、配管の水圧テスト───即ち、配管に水を通し、水圧測定によって水漏 れの有無を確認する───の際、その管継手の（ネジ孔を有する）受口に、合成 樹脂で成型されたテストプラグ（仮栓）を螺合させて止水する。水圧テスト終了 後、テストプラグで仮止水された配管の前方に、配管用の孔を開けた仕上げ用壁 が構築されるが、最近の建築物では、配管受口を壁の前面と同一面上乃至前方に 突出させた状態で壁を設ける場合より、むしろ、受口を壁の後面よりも後方にし た状態で壁を設ける場合が多い。つまり、配管受口は外部から見えないので、（ テストプラグを外して）配管受口から壁前面までの寸法をスケールで測定し、そ の長さに対応する調整用管継手を選定して、この管継手を配管受口に接続して本 格的配管とする。これによって、蛇口が配管に取付け可能となる。 Conventionally, before the construction of the wall of a building, the start-up pipe for waterworks was installed and the elbow pipe fitting (for attaching the faucet) was attached to the end of the pipe. Then, when performing a water pressure test on the pipes, that is, by passing water through the pipes and checking for water leaks by measuring the water pressure, a synthetic resin is applied to the socket (having a screw hole) of the pipe joint. Stop the water by screwing the test plug (temporary plug) molded in. After the completion of the water pressure test, a finishing wall with a hole for piping is built in front of the pipe temporarily stopped by the test plug.However, in recent buildings, the pipe receiving port is flush with the front face of the wall. It is often the case that the wall is installed with the receptacle behind the rear surface of the wall, rather than when the wall is installed with the wall projecting upwards or forwards. In other words, since the pipe socket cannot be seen from the outside, measure the dimension from the pipe socket to the front of the wall (remove the test plug) and select the adjustment fitting that corresponds to the length. This pipe joint is connected to the pipe receiving port to form the standard pipe. This allows the faucet to be attached to the pipe.
【０００３】[0003]
しかしながら、スケールで受口から壁前面までを正確に測定することは手間が かかり、特に、建築物がビル等であると測定箇所が多数であり、作業効率が非常 に悪いという問題があった。そこで、本考案は、上水道の本格的配管前の受口に 取付けて、水圧テストを行え、かつ、本格的配管とするために必要な調整用管継 手を事前に選定することができるテストプラグを提供することを目的とする。 However, it takes a lot of time to accurately measure from the receiving port to the front of the wall with a scale, and there is a problem that the work efficiency is very poor because there are many measurement points especially when the building is a building or the like. Therefore, the present invention is a test plug that can be attached to the receptacle before full-scale piping of waterworks to perform a water pressure test and select in advance the pipe joint for adjustment required for full-scale piping. The purpose is to provide.
【０００４】[0004]
上述の目的を達成するために本考案に係るテストプラグは、盲状孔を有する水 圧テスト用のプラグに於て、外周面に目盛りを付したものである。また、基端側 に相手側の管継手へ螺着される雄ネジ部を設け、かつ、先端側へ開口する盲状孔 を内部に形成した円筒状外周壁を有する水圧テスト用のプラグに於て、上記雄ネ ジ部と上記外周壁との間に形成された段差部を基準として、上記外周壁の外周面 に目盛りが付されたものである。また、本格的配管用の調整用管継手の外径Ｄ0 よりも、円筒状外周壁の外径Ｄが大きく乃至同一に設定されているものである。In order to achieve the above-mentioned object, the test plug according to the present invention is a plug for a hydraulic test having a blind hole with a scale on the outer peripheral surface. Further, in a plug for a hydraulic test having a male screw portion to be screwed to the mating pipe joint on the base end side and having a cylindrical outer peripheral wall having a blind hole opened to the tip end inside.

以下、実施の形態を示す図面に基づき本考案を詳説する。 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment.
【０００６】 図１及び図２は、本考案に係るテストプラグの実施の一形態を示す断面図及び 左側面図であり、このテストプラグは、プラスチック製であり、プラグ本体１の 円筒状外周壁５の内部に盲状孔６を有している。プラグ本体１の先端11側に開口 した孔６は、プラグ本体１の内部から先端11側へ向かって拡径したテーパー状で 、かつ、基端12側の外周壁５と連設した隔壁７によって盲状となる。さらに、孔 ６の内部奥端（基端12側）には、６角形状の多角形孔部10を有し、（その孔部10 は）プラグ本体１取付け時に使用する６角レンチのヘッドに対応した大きさにな っている。FIG. 1 and FIG. 2 are a sectional view and a left side view showing an embodiment of a test plug according to the present invention. The test plug is made of plastic and has a cylindrical outer peripheral wall of a plug body 1. 5 has a blind hole 6 inside. The hole 6 opened to the tip 11 side of the plug body 1 has a tapered shape in which the diameter increases from the inside of the plug body 1 toward the tip 11 side, and is formed by the partition wall 7 continuous with the outer peripheral wall 5 on the base end 12 side. Be blind. Further, a hexagonal polygonal hole portion 10 is provided at the inner rear end of the hole 6 (on the side of the base end 12), and the hexagonal wrench head used when the plug body 1 is attached (the hole portion 10) is provided. It has a corresponding size.
【０００７】 また、プラグ本体１は、その隔壁７から基端12側へ突出した雄ネジ部14を有し ている。この雄ネジ部14は、基端12側を開口した凹部15を内部に有すると共に、 凹部15から***した凸部16を有している。凸部16によって隔壁７は強度を増して いる。また、円筒状外周壁５と雄ネジ部14との間には、段差部17が設けられてい る。Further, the plug body 1 has a male screw portion 14 protruding from the partition wall 7 toward the base end 12 side. The male screw portion 14 has a recess 15 having an opening on the base end 12 side therein and a protrusion 16 protruding from the recess 15. The partition 16 increases the strength by the convex portion 16. Further, a step portion 17 is provided between the cylindrical outer peripheral wall 5 and the male screw portion 14.
【０００８】 図２の左側面図及び図３の一部破断正面図に示す如く、プラグ本体１の先端11 は、６角形状の頭部13を有している。この頭部13の、対面する２面の相互間寸法 は、プラグ本体１外周壁５の外径Ｄに等しい。As shown in the left side view of FIG. 2 and the partially cutaway front view of FIG. 3, the tip 11 of the plug body 1 has a hexagonal head portion 13. The mutual dimension of the two facing surfaces of the head 13 is equal to the outer diameter D of the outer peripheral wall 5 of the plug body 1.
【０００９】 しかして、本考案のテストプラグは、プラグ本体１の外周面２に目盛り３が付 されている。この目盛り３は、雄ネジ部14と外周壁５との間の段差部17を基準と し、先端11側へ１mm単位で表示している。つまり、段差部17が０mmとなる。なお 、目盛り３には、１cmごとに数字が付設されている。さらに、図４の背面図に示 す如く、上記目盛り３の正反対に位置する外周面２にも、同じく目盛り３が付さ れており、どちらか一方の目盛り３，３が測定者の読み取りに容易な位置にくる ように配慮されている。In the test plug of the present invention, the scale 3 is attached to the outer peripheral surface 2 of the plug body 1. The scale 3 is displayed in 1 mm units toward the tip 11 side with reference to the step 17 between the male screw portion 14 and the outer peripheral wall 5. That is, the step portion 17 becomes 0 mm. It should be noted that the scale 3 is provided with a number every 1 cm. Further, as shown in the rear view of FIG. 4, a scale 3 is also provided on the outer peripheral surface 2 located directly opposite to the scale 3, and one of the scales 3 and 3 can be read by a measurer. It is designed so that it is in an easy position.
【００１０】 図５に示すように、建築現場に設けられた上水道の立上り配管20は、その先端 にエルボ型の管継手21が接続される。そして、プラグ本体１の雄ネジ部14を、相 手側であるネジ孔24を有する管継手21の受口19に螺着して、配管20が仮止水され る。その後、配管20に水37を通し、水圧テストによって配管20の水漏れの有無を 確認する。As shown in FIG. 5, an elbow type pipe joint 21 is connected to the tip of a rising pipe 20 for waterworks provided at a construction site. Then, the male screw portion 14 of the plug body 1 is screwed into the receiving port 19 of the pipe joint 21 having the screw hole 24 on the other side, and the pipe 20 is temporarily stopped. After that, water 37 is passed through the pipe 20, and the presence or absence of water leak in the pipe 20 is confirmed by a water pressure test.
【００１１】 そして、図６に示すように、水圧テストの終了後も、配管20の受口19を保護す る上でプラグ本体１が接続されているが、その後、配管20の前方に仕上げ用の壁 22が設けられる。最近の建築物では、（図例の如く）配管20の受口19よりも前の 位置に壁22を設けるという場合が多い。従って、プラグ本体１の位置に壁22が設 けられるため、プラグ本体１の外径Ｄより僅かに大きな貫孔23を形成した壁22が つくられる。この壁22によって、配管20の受口19は外部から遮断されてしまうが 、受口19の先端部26から壁22の前面25までの寸法Ｌを、プラグ本体１外周面２に 付された目盛り３によって測定することができる。As shown in FIG. 6, the plug body 1 is connected to protect the receiving port 19 of the pipe 20 even after the completion of the water pressure test. Wall 22 is provided. In many modern buildings, a wall 22 is often provided at a position before the receptacle 19 of the pipe 20 (as shown in the figure). Therefore, since the wall 22 is provided at the position of the plug body 1, the wall 22 having the through hole 23 slightly larger than the outer diameter D of the plug body 1 is formed. The wall 22 blocks the receiving port 19 of the pipe 20 from the outside, but the dimension L from the tip 26 of the receiving port 19 to the front face 25 of the wall 22 is graduated on the outer peripheral surface 2 of the plug body 1. 3 can be measured.
【００１２】 しかしながら、受口19が壁22の内部にあるため給水栓40を取付けるためには、 図７に示すような、管継手21（受口19）と給水栓40とをつなぐ、調整用の管継手 （雄雌継手）30が必要である。この調整用管継手30は、円筒型の胴部31の内部に 、給水栓40の雄ネジ41と螺合する雌ネジ部32を有し、かつ、胴部31の基端12側か ら突出した中空の雄ネジ部33を有するものである。さらに、雌ネジ部32と中空の 雄ネジ部33との間に、内面が６角形状の（６角レンチ挿入用）多角形孔部50が設 けられている。However, since the receiving port 19 is inside the wall 22, in order to attach the water tap 40, as shown in FIG. 7, the pipe joint 21 (receiving port 19) and the water tap 40 are connected for adjustment. 30 pipe fittings (male-female fitting) are required. The adjustment pipe joint 30 has a female body 32 inside the cylindrical body 31 that engages with a male thread 41 of the water faucet 40, and projects from the base end 12 side of the body 31. It has a hollow male screw portion 33. Further, a polygonal hole portion 50 having a hexagonal inner surface (for inserting a hexagon wrench) is provided between the female screw portion 32 and the hollow male screw portion 33.
【００１３】 しかして、この管継手30を（図６で説明した）配管20受口19に接続するために は、現場の状況に応じたものを選択しなければならない。つまり、受口19先端部 26から壁22前面25までの寸法Ｌ以上で、かつ、貫孔23の径よりも小さい（プラグ 本体１の外径Ｄ以下）ものでなければならない。ここで、管継手30の胴部31の長 さ寸法をＬ0 とし、外径をＤ0 とすると、Ｌ0 ≧Ｌ及びＤ0 ≦Ｄに設定した管継 手30を選定すれば良い。Therefore, in order to connect the pipe joint 30 to the pipe 20 receiving port 19 (described in FIG. 6), it is necessary to select a pipe fitting according to the situation of the site. That is, it must be larger than the dimension L from the tip 26 of the receptacle 19 to the front surface 25 of the wall 22 and smaller than the diameter of the through hole 23 (up to the outer diameter D of the plug body 1). Here, assuming that the length dimension of the body portion 31 of the pipe joint 30 is L 0 and the outer diameter is D 0 , the pipe joint 30 set to L 0 ≧ L and D 0 ≦ D may be selected.
【００１４】 すると、図８に示すように、調整用管継手30を（６角レンチを用いて）配管20 受口19に取付け、本格的配管45（給水栓40取付け前の配管）にすることができる 。つまり、Ｌ0 ≧Ｌであると、管継手30の受口47先端部48は、壁22前面25と同一 面上乃至前方に位置し、Ｄ0 ≦Ｄであると、管継手30は貫孔23を通ることができ るからである。そして、給水栓40を本格的配管45（管継手30受口47）に取付けて 接続作業が完了する。Then, as shown in FIG. 8, the adjustment pipe joint 30 is attached (using a hexagonal wrench) to the pipe 20 receiving port 19 to form a full-scale pipe 45 (pipe before the water tap 40 is attached). Can That is, when L 0 ≧ L, the tip 47 of the receiving port 47 of the pipe joint 30 is located on the same plane as or in front of the front face 25 of the wall 22, and when D 0 ≦ D, the pipe joint 30 has a through hole This is because you can go through 23. Then, the water faucet 40 is attached to the full-scale pipe 45 (pipe joint 30 receiving port 47), and the connection work is completed.
