Description
【０００１】[0001]
本考案は、住宅等の屋内に布設された排水管の漏れを検査する装置に関する。 The present invention relates to a device for inspecting a drain pipe installed indoors such as a house for leaks.
【０００２】[0002]
住宅等を建築する際に、屋内を通るガス管、水道管、排水管等の布設工事は建 物の建築途中で行わなければならない。このため管の布設中あるいは布設後の工 事で配管が傷つけられることがある。 When constructing a house, etc., construction work such as laying gas pipes, water pipes, drainage pipes etc It must be done during the construction of the thing. For this reason, work during or after pipe installation This may damage the piping.
【０００３】 こうした傷の検査は、ガス管、水道管については従来から厳密に行われてきた が、排水管については必ずしも充分とはいえなかった。排水管の漏れは水道管に 比べれば一時的ではあるが長く続けば建物の天井や壁にしみを作り、建物の完成 後に修理工事をするとなると大がかりな工事が必要となる。[0003] Inspection of such scratches has been performed strictly for gas pipes and water pipes. However, the drainage pipe was not always sufficient. Drain pipe leaks into water pipes Comparing it temporarily, but if it continues for a long time, stains are made on the ceiling and walls of the building and the building is completed If repair work is to be done later, large-scale work will be required.
【０００４】 従来の排水管の検査法に満水テストと呼ばれる方法がある。図６でこの方法を 説明する。排水管１は建物の２階から１階床下へと接続された状態にあり、内部 構造を示すために、排水管１の下側端部２の側面を一部取除いてある。また、表 示の都合上、建物の高さに比べ管径を大きく表示してあるが、実際の管径は５０ ｍｍ〜１００ｍｍ、特に家庭用の排水管は通常、５０ｍｍと７５ｍｍが用いられ る。[0004] There is a method called a full water test as a conventional inspection method for drainage pipes. This method is shown in FIG. explain. The drain pipe 1 is connected from the 2nd floor of the building to the 1st floor below, A side surface of the lower end 2 of the drain pipe 1 is partially removed to show the structure. Also, the table For convenience of illustration, the pipe diameter is shown larger than the height of the building, but the actual pipe diameter is 50 mm to 100 mm, especially 50 mm and 75 mm are commonly used for domestic drainage pipes. It
【０００５】 検査を行うには、先ず排水管１の下側端部２を封止することから始める。端部 ２の開口端３からゴム製の封止具４を挿入し、封止具４に空気を送り、膨らませ て排水管１の内壁に強く圧接させて下側開口を封止する。このあと、上側端部５ の開口端から水を注入し、満水状態にして漏れの有無を目視により検査する。[0005] To carry out the inspection, first start by sealing the lower end 2 of the drain pipe 1. edge Insert the rubber sealer 4 from the open end 3 of 2, and send air to the sealer 4 to inflate it. The inner wall of the drainage pipe 1 is strongly pressed to seal the lower opening. After this, the upper end 5 Inject water from the open end of the to make it full of water and visually inspect for leaks.
【０００６】 封止具の従来例の一つを図７に示す。封止具は可撓性の空気注入管６を備えた ゴム製の中空円筒体７からなる。円筒体７を開口端３から挿入し、空気注入管６ を通して円筒体７に空気を注入すると、円筒体は膨張し排水管の内壁に強く圧接 されて下側開口を封止する。[0006] FIG. 7 shows one conventional example of the sealing tool. The closure was equipped with a flexible air infusion tube 6. It consists of a hollow cylindrical body 7 made of rubber. The cylinder 7 is inserted from the open end 3 and the air injection pipe 6 When air is injected into the cylinder 7 through the cylinder, the cylinder expands and strongly presses against the inner wall of the drain pipe. To seal the lower opening.
【０００７】 封止具の他の例として、ゴム板を貫通するボルトに、ゴム板を挟んで一対のナ ットを取り付け、ネジ締めによりゴム板を横方向に変形させて管内壁に圧接する ものもある。[0007] As another example of the sealing tool, a pair of nuts with a rubber plate sandwiched between bolts that penetrate the rubber plate. Mount the tube and tighten the screw to deform the rubber plate laterally and press it against the inner wall of the pipe. There are also things.
【０００８】[0008]
従来の方法は、排水管の下側開口を封止して水を一杯に注入し、目視で検査す るために、多量の水を必要とし、手間も時間もかかるという欠点がある。 The conventional method is to seal the lower opening of the drain pipe, fill it with water, and inspect it visually. Therefore, a large amount of water is required, which is disadvantageous in that it takes time and labor.
【０００９】[0009]
本考案は空気による気密検査を前提とした特別の装置により、水を必要とせず 簡単で、容易に傷等による漏れの有無を検査することを可能とした。すなわち、 本考案の漏洩検査装置は、排水管の一方の開口を封止するゴム製の中空体に２本 の中空管を通し、一方の中空管は、一端に圧力計を取り付け、他端は排水管内に 開口する検査用中空管として構成する。 また、他方の中空管は、一端にタイヤの空気弁（バルブ）のように空気の注入 時には一方向にのみ空気を送り、弁の解放時には逆方向に空気を放出可能とした 第１の空気弁を備え、他端には、ゴム製の中空体の空気圧が一定値以上になると 空気を逃がす第２の空気弁を備えるとともに、中空体内を通る部分に複数の小孔 を有する空気注入管として構成する。 更に、ゴム製の中空体を支持する一対の支持盤とこれを固着した蓋を開口端に 取り付ける保持具を備えている。 また、排水管の他端を封止する封止具として、上記本考案装置の構成で検査用 中空管を省略したものを本考案の漏洩検査装置と共に使用することができる。 以下、更に詳細な構成とその作用について説明する。 The present invention does not require water because it is a special device for air tightness inspection. It is easy and easy to inspect for leaks due to scratches. That is, The leak inspection device of the present invention has two rubber hollow bodies that seal one opening of the drain pipe. Through one of the hollow pipes, one of the hollow pipes has a pressure gauge at one end, and the other end is inside the drain pipe. It is constructed as an open inspection hollow tube. In addition, the other hollow tube is filled with air at one end like a pneumatic valve of a tire. Sometimes air was only sent in one direction, and when the valve was released it could be released in the opposite direction The first air valve is provided, and at the other end, when the air pressure of the rubber hollow body becomes a certain value or more. A second air valve for letting air escape is provided, and a plurality of small holes are provided in the portion passing through the hollow body. It is configured as an air injection pipe having. In addition, a pair of support plates that support the rubber hollow body and a lid that secures the support plates are attached to the open ends. It is equipped with a holder to be attached. In addition, as a sealing tool that seals the other end of the drainage pipe, it is used for inspection with the configuration of the device of the present invention. The one without the hollow tube can be used with the leakage inspection apparatus of the present invention. Hereinafter, a more detailed structure and its operation will be described.

【考案の実施の形態】 図１は本考案の装置を施した排水管の概要を示したもので、建物の２階から１ 階床下へと続く排水管１及びその下側端部２及び上側端部５は図６と同様に表し てある。下側端部２と上側端部５の内側には本考案の装置が設置されており、図 １にはその上部構造が各開口端より外側に見えている。[Embodiment of device] Fig. 1 shows an outline of a drainage pipe equipped with the device of the present invention. The drainage pipe 1 and its lower end 2 and upper end 5 leading to the lower floor are shown in the same manner as in FIG. There is. Inside the lower end 2 and the upper end 5, the device of the present invention is installed. 1, the superstructure is visible outside each open end.

FIG. The sealing device of the present invention installed at the lower end 2 has the following structure. Consists of (A) Hollow body 8 made of rubber and a pair of support plates 9 and 10 for supporting the hollow body 8. (B) A lid 11 having a support board 9 fixed to one surface and attached to the open end 3 of the lower end 2. (C) The lid 11 and the pair of support plates 9 and 10 and the rubber hollow body 8 are penetrated, and the first end is attached to one end. Portion having an air valve 13 and a second air valve 14 at the other end, which penetrates through the rubber hollow body 8. An air injection tube 12 having a plurality of small holes 15 in the.
【００１２】 以上の構成において、第１の空気弁13は、自転車のタイヤに設置されている空 気弁と同様の構造で、空気注入時には一方向にのみ空気を通過させ、弁解放時に は逆方向に空気を放出できるようになっている。また、第２の空気弁14は図５に 示すように一定圧以上になると自動的に弁が開き空気を逃す構造になっている。 以上の構成のほか、開口端に蓋11を確実に固定するために保持具16が使用され る。空気による検査法は、空気圧を増すと封止に使われるゴム製の中空体が管内 で動くため正確な検査が難しく、中空体が抜け出てしまうこともある。このため 中空体を取り付けた蓋をしっかりと開口端に固定する必要がある。[0012] In the above structure, the first air valve 13 is installed on the tire of the bicycle. With the same structure as an air valve, it allows air to pass in only one direction when injecting air, and when opening the valve Is capable of releasing air in the opposite direction. The second air valve 14 is shown in FIG. As shown, when the pressure exceeds a certain level, the valve automatically opens and allows air to escape. In addition to the above configuration, a holder 16 is used to securely fix the lid 11 to the open end. It The air inspection method uses a rubber hollow body that is used for sealing when the air pressure is increased. Since it moves with, accurate inspection is difficult and the hollow body may come out. For this reason The lid with the hollow body must be firmly fixed to the open end.
【００１３】 図３は排水管１の上側端部５に設置された本考案の漏洩検査装置を示したもの である。図３の装置も、構造的には図２に示した封止具と共通の構造を備えてお り、異なる点は、一端に検査用の圧力計が取り付けられ、他端が排水管内に開口 する検査用中空管17が、蓋11、上下一対の支持盤９、10及びゴム製の中空体８を 貫通して設けられていることである。[0013] FIG. 3 shows the leakage inspection device of the present invention installed at the upper end 5 of the drain pipe 1. Is. The device of FIG. 3 also has a structure similar to that of the closure shown in FIG. The difference is that a pressure gauge for inspection is attached to one end and the other end opens into the drain pipe. The inspection hollow tube 17 includes a lid 11, a pair of upper and lower support plates 9 and 10 and a rubber hollow body 8. It is provided to penetrate.
【００１４】 以下、本考案の装置により排水管の開口を封止し、漏れの有無を検査する方法 について説明する。 先ず、図２の封止具のゴム製中空体８を下側端部２の開口端から挿入する。中 空体８は未使用時はしぼんで小さくなっているが、空気を入れたときは球状に近 い形状となり、排水管１の内壁に接触後は押しつけられて図２のように接触面が 平らとなった扁平曲面形状となる。[0014] Hereafter, the method of sealing the drain pipe opening with the device of the present invention and inspecting for leaks Will be described. First, the rubber hollow body 8 of the sealing tool of FIG. 2 is inserted from the open end of the lower end 2. During ~ The empty body 8 is deflated and small when not in use, but when it is filled with air, it has a nearly spherical shape. It becomes a new shape and is pressed after contacting the inner wall of the drain pipe 1 and the contact surface is It becomes a flat and flat curved surface shape.
【００１５】 排水管１内に中空体８を挿入したあと、保持具16を使って蓋11を開口端に固定 する。図４により保持具16の取り付け方を説明する。保持具16は、ハンドル19、 これに固定されたネジ20、ネジの末端に取り付けられた接着片21、及びネジ20が 回転しながら前後進できるようネジ孔を有する直交した板体22からなっている。[0015] After inserting the hollow body 8 into the drainage pipe 1, use the holder 16 to fix the lid 11 to the open end. To do. How to attach the holder 16 will be described with reference to FIG. The holder 16 has a handle 19, The screw 20 fixed to this, the adhesive piece 21 attached to the end of the screw, and the screw 20 It is composed of orthogonal plate members 22 each having a screw hole so that it can move forward and backward while rotating.
【００１６】 蓋11に設けたスリット状の開口23に、板体22の先端に設けた垂下片を挿入して 蓋上に置いた保持具16のハンドル19を回し、接着片21を排水管１の端部側面に強 く密着させる。同様にして図４の２個ある保持具を全て締め付けて蓋をしっかり と固定する。保持具の数は２つ以上でもよいし、また、脱着自在の保持具の代わ りに、蓋の開口23と保持具16の垂下片を省いて保持具16を溶接などで直接蓋11に 固定した構造のものでもよい。[0016] Insert the hanging piece provided at the tip of the plate body 22 into the slit-shaped opening 23 provided in the lid 11. Turn the handle 19 of the holder 16 placed on the lid, and attach the adhesive piece 21 to the side surface of the end of the drain pipe 1. Tightly adhere. In the same way, tighten all the two retainers in Fig. 4 to secure the lid. And fix it. The number of holders may be two or more, and a removable holder may be used instead. In addition, omitting the opening 23 of the lid and the hanging piece of the holder 16, the holder 16 is directly attached to the lid 11 by welding or the like. It may have a fixed structure.
【００１７】 蓋11の取り付けが済んだらば、空気注入管13の先端に、例えば自転車の空気入 れの注入口を接続して空気を送る。第一の空気弁13を通って空気注入管12内に送 り込まれた空気は、複数の小孔15から中空体８内に噴出され中空体８を膨らませ る。空気注入を続けると球状に膨らんだ中空体８は排水管の内壁に圧接され、扁 平な曲面状となって下側端部の開口を封止する。中空体８の内部圧が一定値以上 になると、排水管内に突出した空気注入管12の先端にある第２の空気弁が作動す る。[0017] Once the lid 11 is installed, insert the air in the tip of the air injection pipe 13 Connect these inlets to send air. Send it through the first air valve 13 and into the air injection pipe 12. The air taken in is ejected from the plurality of small holes 15 into the hollow body 8 to inflate the hollow body 8. It When the air injection is continued, the hollow spherical body 8 is pressed against the inner wall of the drainage pipe and flattened. A flat curved surface is formed to seal the opening at the lower end. The internal pressure of the hollow body 8 is above a certain level Then, the second air valve at the tip of the air injection pipe 12 protruding into the drain pipe is activated. It
【００１８】 図５により第２の空気弁14の動作を説明する。空気注入管12に接続される第２ の空気弁14には空気流入口28が設けられている。弁体26の弁座24となる仕切り板 の中央には空気流出口29が設けられている。弁体26は基板25の上にゴムパッキン を固着したもので通常はバネ27により弁座24に押しつけられていて空気注入管12 からくる空気を逃さないように空気流出口29を閉じている。中空体８の空気圧が 、予め設定したバネ圧以上になると弁体26は押されて弁座24との間に空間ができ る。弁体26は空気弁14の内壁との間に隙間ができるように構成されているので空 気注入管12の空気は、排水管１と連絡する放出口30から排水管１内に放出される 。このため過度の圧力によるゴム製中空体８の破損を防止できる。[0018] The operation of the second air valve 14 will be described with reference to FIG. Second connected to the air injection pipe 12 The air valve 14 is provided with an air inlet 28. Partition plate that becomes the valve seat 24 of the valve body 26 An air outlet 29 is provided in the center of the. The valve body 26 is a rubber packing on the substrate 25. Is fixed to the valve seat 24 by the spring 27, and the air injection pipe 12 The air outlet 29 is closed so as not to miss the air coming from it. The air pressure of the hollow body 8 When the spring pressure exceeds a preset value, the valve body 26 is pushed and a space is created between the valve seat 24 and It Since the valve body 26 is configured to have a gap with the inner wall of the air valve 14, it is empty. The air in the air injection pipe 12 is discharged into the drain pipe 1 from the discharge port 30 communicating with the drain pipe 1. . Therefore, damage to the rubber hollow body 8 due to excessive pressure can be prevented.
【００１９】 次に、図３に示す排水管１の上側端部５に使用する本考案装置の取り付け方と 漏れの検査法について説明する。取り付け方は下側端部に使用する本考案の封止 具の場合と同様であるが、図３の装置の場合は、下側端部が既に封止された後に 取り付けるため、また、検査用中空管17が設置されているために動作がやや異な る。すなわち、第１の空気弁13を介してゴム製の中空体８を膨らませて所定圧で 上側開口を封止したのちに第２の空気弁14から放出される空気は、排水管１の両 端が密封されたことで密封空間内の気圧を上昇させる。この気圧の変化は検査用 中空管17を介して圧力計18に表示されるので、所定圧になったら空気の注入を中 止する。この状態で圧力計の目盛りを見ていれば、漏洩があれば圧力が下がり、 漏洩がなければ圧力一定のままとなる。こうして圧力変動の有無により傷等によ る漏れの有無を容易に検査できる。[0019] Next, how to install the device of the present invention used for the upper end 5 of the drain pipe 1 shown in FIG. The leak inspection method will be described. The way to attach is the seal of the present invention used for the lower end Similar to the case of the device, but in the case of the device of FIG. 3 after the lower end has already been sealed. The operation is slightly different due to the installation and because the inspection hollow tube 17 is installed. It That is, the rubber hollow body 8 is inflated through the first air valve 13 and a predetermined pressure is applied. The air released from the second air valve 14 after the upper opening is sealed is discharged from both drainage pipes 1. Since the ends are sealed, the air pressure in the sealed space is increased. This change in atmospheric pressure is for inspection Since it is displayed on the pressure gauge 18 through the hollow tube 17, the air is injected when the pressure reaches a predetermined level. Stop. If you look at the scale of the pressure gauge in this state, if there is a leak, the pressure will drop, If there is no leakage, the pressure remains constant. In this way, due to the presence of pressure fluctuations You can easily inspect for leaks.
【００２０】 検査終了後、本考案の装置を取り外すには、自転車の空気弁と同様に第１の空 気弁13を外部から締め付けているナットをゆるめれば、中空体８内の空気が抜け 、排水管１との密接状態が解放されるので保持具16をゆるめて取り外せばよい。[0020] After inspection, the device of the present invention can be removed by removing the first emptying valve as well as the bicycle air valve. If the nut that tightens the air valve 13 from the outside is loosened, the air inside the hollow body 8 escapes. Since the close contact with the drain pipe 1 is released, the holder 16 may be loosened and removed.
