以下、本発明を実施例により詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to examples.

本発明を図１〜図６に示す一実施例によって説明すれば、建物２内において集水ます１１から差出される排水管１２は建物床下基礎コンクリート１３に埋設されているさや管１５を通って建物外側の排水管１２に地表ＧＬより下位において接続する。   The present invention will be described with reference to an embodiment shown in FIG. 1 to FIG. 6. A drain pipe 12 fed from a water collecting basin 11 in a building 2 passes through a sheath pipe 15 embedded in a foundation concrete 13 under the building floor. Connect to the drain pipe 12 outside the building at a level lower than the surface GL.

該さや管１５は建物２の外側開口端１５Ａから上方に弯曲して建物２の内側開口端１５Ｂが該基礎コンクリート１３上面１３Ａから突出した状態に設定されている。さや管１５の外側開口端１５Ａの側に水平部分を設けても良い。また、内側開口端１５Ｂを基礎コンクリート１３上面１３Ａと面一にしても良い。   The sheath pipe 15 is bent upward from the outer opening end 15A of the building 2 so that the inner opening end 15B of the building 2 protrudes from the upper surface 13A of the foundation concrete 13. A horizontal portion may be provided on the outer opening end 15 </ b> A side of the sheath 15. Further, the inner opening end 15B may be flush with the upper surface 13A of the foundation concrete 13.

該さや管１５内において、該排水管１２の外寄り部分は可撓管１２Ａで構成されており、該可撓管１２Ａの内端には図２に示すように屋内側ソケット１７を介して直管１２Ｂが接続されている。図２および図３に示すように該屋内側ソケット１７の可撓管側端部外周にはねじ部１７Ａが形成されており、直管側端部外周にはリブ１７Ｂが形成され、内周中央部にはストッパー１７Ｃが突設されており、該可撓管１２Ａと該屋内側ソケット１７の可撓管側とは固定ナット１９のフランジ１９Ａを該可撓管１２Ａに装着した樹脂製ストッパーリング２０に引掛け、更に該屋内側ソケット１７のねじ部１７Ａに螺着締付けることによって固定されている。更に該直管１２Ｂと該さや管１５との間にはシールリング２１を介在させることによってそれより内側の水密性を確保している。   In the sheath pipe 15, the outer portion of the drain pipe 12 is constituted by a flexible pipe 12A, and the inner end of the flexible pipe 12A is directly connected via an indoor socket 17 as shown in FIG. A tube 12B is connected. 2 and 3, a threaded portion 17A is formed on the outer periphery of the flexible tube side end of the indoor socket 17, and a rib 17B is formed on the outer periphery of the straight tube side end. A stopper 17C protrudes from the portion, and the flexible tube 12A and the flexible tube side of the indoor socket 17 are made of a resin stopper ring 20 having a flange 19A of a fixing nut 19 attached to the flexible tube 12A. Further, it is fixed by being screwed and tightened to the threaded portion 17A of the indoor side socket 17. Further, a seal ring 21 is interposed between the straight pipe 12B and the sheath pipe 15 to ensure water tightness inside it.

該可撓管１２Ａの外端は図４に示すように屋外側ソケット１６を介して屋外側の排水管１２が接続されている。図４および図５に示すように該屋外側ソケット１６の両端部外周にはねじ部１６Ａ，１６Ｂが形成されており、内周中央部にはストッパー１６Ｃが突設されており、該可撓管１２Ａと該屋外側ソケット１６の可撓管側とは固定ナット２２のフランジ２２Ａを該可撓管１２Ａに装着した樹脂製ストッパーリング２３に引掛け、更に該屋外側ソケット１６のねじ部１６Ｂに螺着締付けることによって固定されており、更に該屋外側ソケット１６の建物２から外出した屋外側端部のねじ部１６Ａには位置決めナット２４が螺着締付けられている。そして該可撓管１２Ａの外端は、屋外側ソケット１６を介して該位置決めナット２４によってフランジ２４Ａを建物床下基礎コンクリート層１３、又は、さや管１５の端面に押し当てることで、さや管１５開口に対して位置決め固定されている。該位置決めナット２４は図６に示すように内端にフランジ２４Ａおよび外周にリブ２４Ｂが設けられており、内周には断続的にねじ溝２４Ｃが形成されている。該位置決めナット２４の螺着締付けには該リブ２４Ｂを手掛りとする。なお該可撓管１２Ａと該屋外側および屋内側ソケット１６，１７との間にはシールリング２５，２６によってシールされている。   As shown in FIG. 4, the outer end of the flexible tube 12 </ b> A is connected to the outdoor-side drain pipe 12 via the outdoor-side socket 16. As shown in FIGS. 4 and 5, threaded portions 16A and 16B are formed on the outer periphery of both end portions of the outdoor side socket 16, and a stopper 16C is projected from the central portion of the inner periphery. 12A and the flexible tube side of the outdoor socket 16 are hooked on the resin stopper ring 23 attached to the flexible tube 12A with the flange 22A of the fixing nut 22 and further screwed onto the threaded portion 16B of the outdoor socket 16. The positioning nut 24 is screwed and fastened to the threaded portion 16A of the outdoor side end portion of the outdoor side socket 16 that has come out of the building 2. The outer end of the flexible tube 12A is opened to the sheath tube 15 by pressing the flange 24A against the bottom concrete floor 13 of the building floor or the end surface of the sheath tube 15 by the positioning nut 24 through the outdoor socket 16. It is fixed to the position. As shown in FIG. 6, the positioning nut 24 is provided with a flange 24A on the inner end and a rib 24B on the outer periphery, and a thread groove 24C is intermittently formed on the inner periphery. The rib 24B is used as a cue for screwing and tightening the positioning nut 24. The flexible tube 12A is sealed between the outdoor side and indoor side sockets 16 and 17 by seal rings 25 and 26.

上記配管構造を配管施工するには、例えば可撓管１２Ａの一端に屋内側ソケット１７を介して鋸等の簡単な工具で切断することによって所定長に調節した直管１２Ｂを接続し、該直管１２Ｂの外周にはシールリング２１を装着し、他端に屋外側ソケット１６を装着する（工程２）。該直管１２Ｂは可撓管１２Ａのように不安定形状ではないので切断作業は容易である。また、継手２７を介して排水管１２と容易に接着接合出来る。このような直管１２Ｂ−屋内側ソケット１７−可撓管１２Ａ−屋外側ソケット１６を接続したセットを屋内側からさや管１５に挿通する。この際には屋外側ソケット１６を先頭にする。該可撓管１２Ａは直管１２Ｂを接続した分短くなっているから、さや管１５に挿通する際弯曲したり折曲しにくいので、挿通作業は容易に出来る。また該直管１２Ｂの外周には予めシールリング２１を装着してあるので、該セットを該さや管１５に挿通すると同時に該直管１２Ｂと該さや管１５との間が該シールリング２１によってシールされることになる（工程３）。該直管１２Ｂには継手２７を介して屋内側の排水管１２が接続されるが該直管１２Ｂは該シールリング２１によってさや管１５内に固定されているので、屋内側排水管１２の接続作業が容易になる。   To construct the piping structure, for example, a straight pipe 12B adjusted to a predetermined length by cutting with a simple tool such as a saw through the indoor socket 17 is connected to one end of the flexible pipe 12A. The seal ring 21 is attached to the outer periphery of the tube 12B, and the outdoor side socket 16 is attached to the other end (step 2). Since the straight pipe 12B is not an unstable shape like the flexible pipe 12A, the cutting operation is easy. Further, it can be easily bonded to the drain pipe 12 via the joint 27. A set in which such a straight pipe 12B-indoor side socket 17-flexible pipe 12A-outdoor side socket 16 is connected is inserted into the sheath pipe 15 from the indoor side. At this time, the outdoor side socket 16 is placed at the top. Since the flexible tube 12A is shortened by connecting the straight tube 12B, it is difficult to bend or bend when inserted into the sheath tube 15, and therefore the insertion operation can be easily performed. Since the seal ring 21 is mounted on the outer periphery of the straight pipe 12B in advance, the seal ring 21 seals between the straight pipe 12B and the sheath pipe 15 at the same time as the set is inserted into the sheath pipe 15. (Step 3). An indoor drain pipe 12 is connected to the straight pipe 12B via a joint 27. Since the straight pipe 12B is fixed in the sheath pipe 15 by the seal ring 21, the connection of the indoor drain pipe 12 is performed. Work becomes easy.

その後該屋外側ソケット１６の屋外端に設けられたねじ部１６Ａに対して位置決めナット２４を螺着締付ける。該可撓管１２Ａの屋外端側は該屋外側ソケット１６を介して該位置決めナット２４によって位置決め固定されており、可撓管１２Ａの外端のさや管１５開口に対する角度決めが可能となるため、該屋外側ソケット１６に屋外側排水管１２を接続する作業は容易に出来る。   Thereafter, the positioning nut 24 is screwed and tightened to the screw portion 16A provided at the outdoor end of the outdoor socket 16. The outdoor end side of the flexible tube 12A is positioned and fixed by the positioning nut 24 via the outdoor side socket 16, and the angle of the outer end sheath of the flexible tube 12A to the sheath 15 opening can be determined. The operation | work which connects the outdoor side drain pipe 12 to this outdoor side socket 16 can be done easily.

結果として、位置決めナット２４をシールリング２１との二点固定になるため、可撓管１２Ａおよび直管１２Ｂがさや管１５の中で安定する。   As a result, since the positioning nut 24 is fixed to the seal ring 21 at two points, the flexible tube 12A and the straight tube 12B are stabilized in the sheath tube 15.

本発明では、さや管１５と排水管１２とのシール構造は、位置決めナット２４とさや管１５又は床基礎コンクリート層１３との間に設けても良い。また、可撓管１２Ａやソケット１６，１７とさや管１５との間に設けても良い。   In the present invention, the seal structure between the sheath tube 15 and the drain tube 12 may be provided between the positioning nut 24 and the sheath tube 15 or the floor foundation concrete layer 13. Further, it may be provided between the flexible tube 12 </ b> A or the sockets 16, 17 and the sheath tube 15.

シールリング２１としては、ゴム製パッキンやオーリングが好ましい。この種のシールリング２１を直管１２Ｂに装着しておくと、シール材の取付け作業を別途行う必要がなくなり、また、シール剤の充填作業が不要となる点で好適である。   As the seal ring 21, rubber packing or O-ring is preferable. If this type of seal ring 21 is attached to the straight pipe 12B, it is not necessary to separately perform an attaching operation of the sealing material, and it is preferable in that a filling operation of the sealing agent is unnecessary.

本実施例の場合には、シールリング２１をさや管１５の屋内側としたので、可撓管１２Ａおよび直管１２Ｂをさや管１５に挿入する際の圧入距離が短く、圧入力が小さくて済む点で好ましい。また、直管１２Ｂとさや管１５との間でシールしており、さや管１５と排水管１２との間の隙間が不均一となる弯曲部ではなく、該隙間が均一になりやすい直線部でシールすることになるから、シール性を高めることが出来る。   In the case of the present embodiment, since the seal ring 21 is on the indoor side of the sheath tube 15, the press-fitting distance when the flexible tube 12A and the straight tube 12B are inserted into the sheath tube 15 is short, and the pressure input is small. This is preferable. In addition, the straight pipe 12B and the sheath pipe 15 are sealed, and the gap between the sheath pipe 15 and the drain pipe 12 is not a curved portion where the gap is uneven, but the straight portion where the gap is likely to be uniform. Since sealing is performed, sealing performance can be improved.

本発明では建物内の排水配管が簡単かつ容易な作業で出来るから、産業上利用可能である。   In the present invention, drainage pipes in buildings can be used in an industrial manner because they can be done with simple and easy work.
