Description
【０００１】[0001]
本考案は、建築物の建築途中において床や壁の内部に配管される上水道管の開 口先端部に予め螺合嵌入させて上水道管の通水試験を行う仮止水栓に関するもの である。 The present invention relates to a temporary stopcock for performing a water passage test of a water supply pipe by screwing it into the opening tip of the water supply pipe that is piped inside a floor or a wall in the middle of building a building.
【０００２】[0002]
建築物の基礎工事や躯体工事等が終了した建築工事現場では、壁等を構築する 前の段階で工事の段取りとして上水道管が予め配管され、その開口先端部は、台 所や風呂場等の水を使用する部分で蛇口となる位置に立ち上げた状態で配置され ており、内装工事等がほとんど終了後に蛇口等の上水道器具を装着することにな る。 At the construction site where the foundation work and skeleton work of the building have been completed, the water supply pipe is piped in advance as a setup for the work before the walls are constructed, and the opening tip of the water pipe is located in the basin or bathroom. The water is used at the location where it will be used as a faucet, and it will be installed after the completion of the interior work, etc.
【０００３】 しかし、建築工事中には様々な事情でこの予め配管された上水道管が破損する ことがあり、破損したままの状態で内装工事を進めて、完成してから上水道管に 通水すると、破損事実が判明しなかったり、漏水個所が不明であったり、更には 漏水個所が判明しても補修が困難だったりする。However, during the construction work, the pre-installed water supply pipe may be damaged due to various reasons. If the interior work is advanced in the damaged condition and water is supplied to the water supply pipe after completion. However, the fact of damage is not known, the location of the leak is unknown, and even if the location of the leak is found, repair is difficult.
【０００４】 このため、上水道管を予め配管した状態で通水して水圧をかけた通水試験を行 い、内装等の工事中に誤って上水道管を破損したような場合に、直ちにその事実 を発見し補修できるようにしている。Therefore, when a water supply test is performed by applying water pressure by passing water in a state in which the water supply pipe is preliminarily piped, and if the water supply pipe is accidentally damaged during construction of the interior, the fact immediately We are able to discover and repair.
【０００５】 しかし、建築物の内装が完了してない段階であるから、上水道管の開口先端部 に蛇口等を装着しておく訳にはいかず、従ってこの開口先端部には漏水がないよ うに仮止水栓を漏水不能に嵌入装着する。However, since the interior of the building is not yet completed, it is not possible to attach a faucet or the like to the opening end of the water supply pipe, and therefore there is no water leakage at this opening end. Insert the temporary stopcock so that it cannot leak.
【０００６】 この仮止水栓は、上水道管の開口先端部に螺合嵌入する嵌合筒部に拡径のプラ グ部を連設し、内部に止水用隔壁を設けて閉鎖された構成であるが、工事作業時 の水道器具取り付け位置の目安や壁の厚み等の関係で、プラグ部の部分は数セン チほど横方向に突出した構造となっている。In this temporary water stopper, a plug portion having a larger diameter is continuously provided to a fitting cylinder portion that is screwed into an opening end portion of a water supply pipe, and a water-stopping partition wall is provided inside to close the plug. However, the structure of the plug part has a structure that protrudes laterally by several centimeters, depending on the guideline of the location of water fixtures and wall thickness during construction work.
【０００７】 そして、この仮止水栓は、廉価であること、軽量であること、錆びないこと、 取り扱い易いこと、上水道管の開口先端部を漏水不能に螺合させることなどの理 由から、比較的安価な合成樹脂で成形されている。[0007] The temporary stopcock is inexpensive, lightweight, does not rust, is easy to handle, and screw-engages the opening end of the water supply pipe so that water cannot leak. It is molded from relatively inexpensive synthetic resin.
【０００８】[0008]
しかしながら、上述したようにプラグ部の部分は数センチほど横方向に突出し た構造となっているので、大工工事や左官工事等の内装工事の過程では格好の足 場になることが多く、この部分に作業者の体重がかかるため、折損事故が絶えな かった。 However, as mentioned above, the plug part has a laterally protruding structure of several centimeters, so it is often a good scaffold in the process of interior work such as carpentry work and plastering work. Since the worker's weight is heavy, the breakage accidents were constant.
【０００９】 このため、特にプラグ部の部分を厚肉にして強度を高める等の対策がとられて きたが、折損部分は殆どの場合、プラグ部と嵌合筒部との境界部分に発生してい るので効果がなく、上水道管の開口先端部内に嵌合筒部のみが残存してしまい、 この嵌合筒部が外れなくなるという問題もあった。Therefore, although measures have been taken to increase the strength, especially by increasing the thickness of the plug portion, the broken portion almost always occurs at the boundary between the plug portion and the fitting cylinder portion. Since there is no effect, there is also a problem that only the fitting cylinder part remains in the opening tip part of the water supply pipe, and the fitting cylinder part cannot be removed.
【００１０】 そして、嵌合筒部の外周面に刻設されている雄螺子は、プラグ部との連続部分 である嵌合筒部の基端部にまで設けられている。したがって、プラグ部の部分に 作業者の体重等の負荷や衝撃が加わると、嵌合筒部の外周面に刻設された螺子の 谷部が機械的にノッチ現象を果たしてしまい、外部からの衝撃が梃子作用となっ て螺子部の一点に直接集中する。折損原因の殆どは、このノッチ現象による衝撃 の一点集中にあり、このため、プラグ部と嵌合筒部との連続部分で折損してしま うのである。Further, the male screw engraved on the outer peripheral surface of the fitting tubular portion is provided up to the base end portion of the fitting tubular portion which is a continuous portion with the plug portion. Therefore, when a load such as a worker's weight or an impact is applied to the plug part, the valley of the screw thread engraved on the outer peripheral surface of the fitting cylinder part mechanically performs the notch phenomenon, and the impact from the outside. Acts as a lever and concentrates directly on one point of the screw. Most of the causes of breakage are concentrated at one point of the impact due to the notch phenomenon, and therefore, the breakage occurs at the continuous portion between the plug portion and the fitting cylinder portion.
【００１１】 一方、上水道管と仮止水栓との間の止水手段は、従来一般にシールテープを螺 子部に巻装することによって構成されている。しかしながら、シールテープの巻 装作業は熟練技術が必要であると共に手間暇の掛かる作業であった。そこで、特 開平７−１２０３４８号公報による配水管の水洩れ試験用止水プラグのように、 把手部に突設したネジ軸部に嵌装したリングパッキンにより、上水道管の雌螺子 部よりも外側で止水するようにしたものが提案されている。On the other hand, the water stop means between the water supply pipe and the temporary water stopcock has heretofore been generally constituted by winding a seal tape around the screw portion. However, the winding work of the sealing tape requires a skilled technique and is time-consuming work. Therefore, as in the water leakage test plug for water leak of water distribution pipe disclosed in Japanese Patent Publication No. 7-120348, the ring packing fitted to the screw shaft portion protruding from the handle portion is located outside the female screw portion of the water supply pipe. It has been proposed to stop the water in.
【００１２】 しかしながら、従来のリングパッキンを利用した仮止水栓は、上水道管の端面 と仮止水栓の端面との間にリングパッキンを挟着する構成である。このため充分 な止水効果が得られていないのが現状である。即ち、上水道管の端面が平滑でな いため、リングパッキンとの間に隙間が生じ易い。また、端面にバリ等が生じて いるとリングパッキンに傷が付き易く、この傷が原因でリングパッキンが破損す る事故が発生している。 本考案は上記に鑑み提案されたもので、シールテープを用いることなく確実な 止水効果を達成すると共に、強度を高めた仮止水栓を提供することを目的とする 。[0012] However, the conventional temporary water stop using the ring packing has a structure in which the ring packing is sandwiched between the end surface of the water supply pipe and the end surface of the temporary water stop. For this reason, the current situation is that a sufficient water-stopping effect has not been obtained. That is, since the end surface of the water supply pipe is not smooth, a gap is likely to be formed between the water supply pipe and the ring packing. In addition, if burr or the like is generated on the end surface, the ring packing is easily damaged, and this damage causes the ring packing to be damaged. The present invention has been proposed in view of the above, and an object thereof is to provide a temporary water stopcock that achieves a reliable water-stopping effect without using a sealing tape and has increased strength.
【００１３】[0013]
上記課題を解決するため本考案は、建築物の建築途中の上水道管の開口先端部 に開口端面側が拡径する面取部を形成し、この開口先端部に螺合嵌入させて上水 道管の通水試験を行う仮止水栓であって、開口先端部内に螺合嵌入する嵌合筒部 と、該嵌合筒部に連設して設けた拡径するプラグ部とを備え、前記嵌合筒部とプ ラグ部とが連続する嵌合筒部の基端部分に、前記面取部に対応する押圧嵌入部を 形成し、上記押圧嵌入部の前端部分にリング状のシール材を嵌め込み、前記嵌合 筒部を上水道管の開口先端部に螺合嵌入させたときに、上記シール材が開口先端 部の開口端縁に形成した面取部に圧接して止水するようにしたものである。 In order to solve the above problems, the present invention forms a chamfered portion at the opening end of a water supply pipe in the middle of construction of a building, the diameter of the opening end side of which expands, and is screwed into the opening end to make a water pipe. A temporary stop cock for performing a water passage test, comprising: a fitting cylinder part that is screw-fitted into the opening tip part; and a plug part that is provided continuously to the fitting cylinder part and that has an enlarged diameter. A press fitting portion corresponding to the chamfered portion is formed at the base end portion of the fitting tubular portion where the fitting tubular portion and the plug portion are continuous, and a ring-shaped sealing material is provided at the front end portion of the press fitting portion. When the fitting tubular part is fitted and screwed into the opening end part of the water supply pipe, the sealing material is brought into pressure contact with the chamfered part formed at the opening edge of the opening end part to stop water. It is a thing.

以下に本考案の実施の形態を図面に基づいて詳細に説明すると、建築物の工事 現場で予め配管される上水道管１の開口先端部には、通常ではＬ型継手２が螺合 装着されており、このＬ型継手２の開口端部内面には雌螺子３が形成されている 。また、このＬ型継手２の雌螺子３の開口縁、或は上水道管１の開口先端部には 、開口端面側が拡径する傾斜した面取部４が形成されている。尚、この面取部４ の傾斜角や仕上等はＪＩＳ規格によって定められており、規格に則って製造され て検定を合格した製品でなければ、使用することができない。また、Ｌ型継手２ 内には、水道水が金属部分に触れるのを防ぐ目的で合成樹脂製の内管を嵌め込ん でおいてもよい。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Normally, an L-shaped joint 2 is screwed and attached to an opening end portion of a water supply pipe 1 which is preliminarily piped at a construction site of a building. A female screw 3 is formed on the inner surface of the open end of the L-shaped joint 2. An inclined chamfered portion 4 is formed at the opening edge of the female screw 3 of the L-shaped joint 2 or at the opening end portion of the water supply pipe 1 so that the diameter of the opening end surface side increases. In addition, the inclination angle and finish of the chamfered portion 4 are defined by JIS standard, and only a product manufactured according to the standard and having passed the certification can be used. In addition, an inner pipe made of synthetic resin may be fitted in the L-shaped joint 2 in order to prevent tap water from coming into contact with the metal part.
【００１５】 本考案に係る仮止水栓５は、比較的硬質で、強度に優れた合成樹脂で成形され 、Ｌ型継手２内に嵌入してその雌螺子３に螺合する雄螺子６を形成した嵌合筒部 ７の端部に、拡径したプラグ部８を一体に連設した構造である。The temporary stop cock 5 according to the present invention is made of a synthetic resin that is relatively hard and has excellent strength, and has a male screw 6 that is fitted into the L-shaped joint 2 and screwed into its female screw 3. This is a structure in which the expanded plug portion 8 is integrally connected to the end portion of the formed fitting tubular portion 7.
【００１６】 図示の実施形態では、嵌合筒部７とプラグ部８の連続部内に止水用の隔壁７１ を設け、前記したように内部に内管が存在するＬ型継手２にも対応できるように 構成してある。即ち、Ｌ型継手２内に嵌合した嵌合筒部７の内部に内管が嵌入で きるようになっており、嵌合筒部７をＬ型継手２の開口端から強固に螺合嵌入し ても、内管が損傷してしまうことがない。一方、内管が存在しない継手にのみ対 応させる場合には、隔壁７１を嵌合筒部７の嵌入先端部分に設けることもできる 。In the illustrated embodiment, a partition wall 71 for stopping water is provided in the continuous portion of the fitting cylinder portion 7 and the plug portion 8 and, as described above, the L-shaped joint 2 having the inner pipe therein can also be accommodated. It is configured as follows. That is, the inner pipe can be fitted into the fitting cylindrical portion 7 fitted in the L-shaped joint 2, and the fitting cylindrical portion 7 is firmly screwed and fitted from the opening end of the L-shaped joint 2. However, the inner tube will not be damaged. On the other hand, when the fitting is made to correspond only to the joint in which the inner pipe does not exist, the partition wall 71 may be provided at the fitting tip portion of the fitting tubular portion 7.
【００１７】 前記嵌合筒部７の端部とプラグ部８とが連続する嵌合筒部７の基端部分には、 外径ｄ1 が前記した面取部４の外周径Ｄ1 よりも小径で且つ内周径Ｄ2 よりも大 径な押圧嵌入部７２を形成する。また、この押圧嵌入部７２に連続して当該押圧 嵌入部７２よりも小径で、嵌合筒部７の雄螺子６の谷部分と同等または谷部分よ り深い外径ｄ2 を有する環状溝部７３を形成する。そして、この環状溝部７３内 にはゴム等の弾性材で成形された外径ｐを有するリング状のシール材９を、パッ キン材及びクッション材として嵌め込む。このシール材９の外径ｐは、前記した 面取部４の外径ｄ1 より小径で有ると共に、面取部４の外周径Ｄ1 よりは小径で ある。尚、上記各径の関係を整理すると、ｄ2≦Ｄ2＜ｄ1＜ｐ≦Ｄ1 となってい る。At the base end portion of the fitting cylinder portion 7 where the end portion of the fitting cylinder portion 7 and the plug portion 8 are continuous, the outer diameter d1 is smaller than the outer diameter D1 of the chamfered portion 4 described above. In addition, the press fitting portion 72 having a diameter larger than the inner diameter D2 is formed. In addition, an annular groove portion 73 having a diameter smaller than that of the press-fitting portion 72 and having an outer diameter d2 which is smaller than that of the press-fitting portion 72 and is equal to or deeper than the valley portion of the male screw 6 of the fitting tubular portion 7 is formed. Form. Then, a ring-shaped sealing material 9 having an outer diameter p and made of an elastic material such as rubber is fitted into the annular groove portion 73 as a packing material and a cushion material. The outer diameter p of the sealing material 9 is smaller than the outer diameter d1 of the chamfered portion 4 and smaller than the outer peripheral diameter D1 of the chamfered portion 4. When the relationship among the above diameters is arranged, d2≤D2 <d1 <p≤D1.
【００１８】 上記リング状のシール材９は断面が円形であるが、Ｌ型継手２内の雌螺子３と 嵌合筒部７の雄螺子６とを螺合させてＬ型継手２内に嵌合筒部７を螺合嵌合させ た際、Ｌ型継手２の開口端縁に形成した面取部４の斜面４１と、対向する押圧嵌 入部７２の前端面、即ち図示した実施の形態では環状溝部７３の内端面との間に 挟持されて圧力を受けると或る程度潰れてパッキン効果及びクッション効果を発 揮する。このとき、図示の実施の形態においては、押圧嵌入部７２の外径ｄ1 が 面取部４の外周径Ｄ1 よりも小さく、面取部４の内周径ｄ2 よりは大きいと共に 、シール材９の外径ｐが押圧嵌入部７２の外径ｄ1 よりも大径であるので、シー ル材９を面取部４に対して確実に押圧すると共に、シール材９が斜面４１に密接 して楔状に作用し、シール効果を遺憾なく発揮する。The ring-shaped sealing material 9 has a circular cross section, but the female screw 3 in the L-shaped joint 2 and the male screw 6 of the fitting tubular portion 7 are screwed into each other to fit into the L-shaped joint 2. When the fitting cylinder portion 7 is screw-fitted, the sloped surface 41 of the chamfered portion 4 formed at the opening end edge of the L-shaped joint 2 and the front end surface of the opposing pressure fitting portion 72, that is, in the illustrated embodiment. When it is sandwiched between the inner end surface of the annular groove portion 73 and pressure is applied, the annular groove portion 73 is crushed to some extent and exhibits a packing effect and a cushioning effect. At this time, in the illustrated embodiment, the outer diameter d1 of the press-fitting portion 72 is smaller than the outer peripheral diameter D1 of the chamfered portion 4, larger than the inner peripheral diameter d2 of the chamfered portion 4, and the sealing material 9 is Since the outer diameter p is larger than the outer diameter d1 of the press-fitting portion 72, the seal material 9 is surely pressed against the chamfered portion 4, and the seal material 9 is closely contacted with the inclined surface 41 to form a wedge shape. It works and shows the sealing effect fully.
【００１９】 また、図示の実施の形態では、Ｌ型継手２内に雌螺子３と雄螺子６とを螺合さ せて嵌合筒部７に螺合嵌合させたとき、プラグ部８の端面とＬ型継手２の開口先 端部の端面との間に間隙ｌが生じているので、Ｌ型継手２の端面の仕上がりが粗 雑であって凹凸が存在するような場合であっても、充分なシール効果が得られる 。また、端面にバリ等が生じていても、シール材９には接触しないので、シール 材９が傷付いたり、この傷が原因でシール材９が破損することがない。Further, in the illustrated embodiment, when the female screw 3 and the male screw 6 are screwed into the L-shaped joint 2 and screwed into the fitting cylinder portion 7, the plug portion 8 is Since a gap 1 is formed between the end surface and the end surface of the opening end of the L-shaped joint 2, even if the end surface of the L-shaped joint 2 has a rough finish and unevenness is present. A sufficient sealing effect can be obtained. Further, even if burrs or the like are generated on the end surface, the sealing material 9 does not come into contact with the sealing material 9, and the sealing material 9 will not be damaged due to the damage.
【００２０】 そして、この押圧力を受けてシール材９が外方に弾性変形しようとしても、面 取部４の斜面４１によってシール材９の外方向への変形が防止される。また、前 記したように変形しようとするシール材９が斜面４１に密接して楔状に作用する ので、シール材９によるパッキン効果及びクッション効果が著しく増加する。Even if the sealing material 9 is elastically deformed outward due to the pressing force, the inclined surface 41 of the chamfered portion 4 prevents the sealing material 9 from being deformed in the outward direction. Further, as described above, the sealing material 9 which is about to deform acts closely on the slope 41 and acts like a wedge, so that the packing effect and the cushioning effect of the sealing material 9 are significantly increased.
【００２１】 一方、前記したプラグ部８は、Ｌ型継手２の外径とほぼ同一の外径であり、前 端部分を六角形状にして、仮止水栓５をＬ型継手２に螺合嵌入する場合、及び外 す場合に、レンチ等の工具を係合させて回転し易くする六角形状部８１が形成し てある。On the other hand, the plug portion 8 has an outer diameter substantially the same as the outer diameter of the L-shaped joint 2, and the front end portion has a hexagonal shape, and the temporary stop cock 5 is screwed into the L-shaped joint 2. A hexagonal portion 81 is formed to facilitate rotation by engaging a tool such as a wrench when inserting and removing.
【００２２】 しかし、建築物の壁Ａ等の施工時にＬ型継手２を通す開口部Ｂを開設する際、 この開口部Ｂの直径はＬ型継手２の周面に接する位にできるだけ小さい方が望ま しいのであるが、先端部分の対角線の長さがプラグ部８の外周より大きいと、前 記開口部Ｂの開口直径も大きくならざるを得ない。そこで、図示の実施形態では 、プラグ部８の先端部分の六角形状部８１の対角線の長さを、プラグ部８の外形 とほゞ等しくなるように形成している。However, when opening the opening B through which the L-shaped joint 2 is passed when constructing a wall A of a building, the diameter of this opening B should be as small as possible so as to contact the peripheral surface of the L-shaped joint 2. Desirably, if the length of the diagonal line of the tip portion is larger than the outer circumference of the plug portion 8, the opening diameter of the opening B is inevitably large. Therefore, in the illustrated embodiment, the length of the diagonal line of the hexagonal portion 81 at the tip portion of the plug portion 8 is formed to be substantially equal to the outer shape of the plug portion 8.
【００２３】 尚、図示実施形態では、嵌合筒部７とプラグ部８との連続部内に設けた止水用 の隔壁７１の中央部に***部７４を設けている。この***部７４は隔壁７１の強 度をより確保するためのもので、外部からの衝撃に対し、当該部分での破損を防 止するための機能を果たす。In the illustrated embodiment, the raised portion 74 is provided at the center of the water blocking partition 71 provided in the continuous portion of the fitting tubular portion 7 and the plug portion 8. The raised portion 74 serves to further secure the strength of the partition wall 71, and has a function of preventing damage to the portion against external impact.
【００２４】 また、プラグ部８の内部奥端には多角形状の空部８２を有し、多角形レンチの 先端部を挿着して仮止水栓５を回転できるようにしているので、上水道管１の開 口先端部に螺合嵌入した仮止水栓５を強く締めつけたり、または外したりするこ とができる。In addition, a polygonal empty portion 82 is provided at the inner rear end of the plug portion 8 so that the temporary water stopper 5 can be rotated by inserting the tip end portion of the polygonal wrench. It is possible to strongly tighten or remove the temporary stopcock 5 that is screwed into the open end of the pipe 1.
【００２５】 図５は、本考案の他の実施形態を示す断面図であり、この実施形態では、上水 道管１の開口先端部を樹脂管によって形成し、面取部４を当該樹脂管の開口端縁 に形成したものである。FIG. 5 is a cross-sectional view showing another embodiment of the present invention. In this embodiment, the opening tip of the water supply pipe 1 is formed by a resin pipe, and the chamfered portion 4 is formed by the resin pipe. It is formed on the opening edge of the.
【００２６】 即ち、上水道管１の開口先端部を、合成樹脂で成形した段付パイプ１１内に真 鍮等の錆難い金属で形成した螺子管１２を装着した直管継手２１により形成した ものである。That is, the opening tip of the water supply pipe 1 is formed by a straight pipe joint 21 in which a screw pipe 12 made of a metal such as brass that is not easily rusted is mounted in a stepped pipe 11 made of synthetic resin. is there.
【００２７】 段付パイプ１１は、一端側が拡径して、この拡径した側に、内周面に雌螺子３ を有する螺子管１２をインサート成形等により装着して構成する。そして、この 雌螺子３の開口端縁に、前記した実施の形態と同様に、規格に沿って面取部４を 形成する。The stepped pipe 11 is configured such that one end side is expanded in diameter, and a screw tube 12 having a female screw 3 on the inner peripheral surface is attached to the expanded side by insert molding or the like. Then, the chamfered portion 4 is formed on the opening edge of the female screw 3 in accordance with the standard as in the above-described embodiment.
【００２８】 一方、上記のような樹脂管に螺合嵌合させる仮止水栓５は、前記したように開 口先端部内に螺合嵌入する嵌合筒部７と、該嵌合筒部７に連設して設けた拡径す るプラグ部８とを備え、嵌合筒部７の端部とプラグ部８とが連続する嵌合筒部７ の基端部分には、外径ｄが面取部４の外周径Ｄ1 よりも小径で且つ内周径Ｄ2 よ りも大径な押圧嵌入部７２を形成する。また、この押圧嵌入部７２に連続して当 該押圧嵌入部７２よりも小径で、嵌合筒部７の雄螺子６の谷部分より深い環状溝 部７３を形成する。そして、この環状溝部７３内にはゴム等の弾性材で成形され たリング状のシール材９を、パッキン材及びクッション材として嵌め込む。On the other hand, the temporary water stopper 5 screw-fitted into the resin pipe as described above has the fitting cylinder portion 7 screw-fitted into the opening tip portion as described above, and the fitting cylinder portion 7 And a plug portion 8 having a larger diameter, which is continuously provided on the base portion of the fitting tubular portion 7 where the end portion of the fitting tubular portion 7 and the plug portion 8 are continuous with each other. A press fitting portion 72 having a diameter smaller than the outer diameter D1 of the chamfered portion 4 and larger than the inner diameter D2 is formed. Further, an annular groove portion 73, which has a smaller diameter than the pressing fitting portion 72 and is deeper than the valley portion of the male screw 6 of the fitting tubular portion 7, is formed continuously with the pressing fitting portion 72. Then, the ring-shaped sealing material 9 formed of an elastic material such as rubber is fitted into the annular groove portion 73 as a packing material and a cushion material.
【００２９】 上記のような構成の樹脂管に本考案に係る仮止水栓５を適用しても、シール材 ９を押圧嵌入部７２によって確実に押圧すると共に、シール材９が面取部４の斜 面４１に密接して楔状に作用してシール効果を遺憾なく発揮する。また、直管継 手２１の端面に凹凸やバリ等が存在していても、シール効果が損なわれることが なく、シール材９が破損することもない。更に、押圧力を受けてシール材９が外 方に弾性変形しようとしても、この変形を面取部４の斜面４１が防止すると共に 、斜面４１に密接して楔状に作用するのでパッキン効果及びクッション効果が著 しく増大する。Even when the temporary water stopper 5 according to the present invention is applied to the resin pipe having the above-mentioned structure, the seal material 9 is surely pressed by the press fitting portion 72, and the seal material 9 is chamfered. It closely acts on the slope 41 and acts like a wedge to fully exert the sealing effect. Further, even if the end face of the straight pipe joint 21 has irregularities, burrs or the like, the sealing effect is not impaired and the sealing material 9 is not damaged. Further, even if the sealing material 9 is elastically deformed outward due to a pressing force, this deformation is prevented by the sloped surface 41 of the chamfered portion 4, and the sloped surface 41 is closely contacted with the sloped surface 41 so as to act like a wedge. The effect is significantly increased.
【００３０】 以上、本考案を図面の実施形態に基づいて説明したが、本考案は上記した実施 形態に限定されるものではなく、実用新案登録請求の範囲に記載の構成を変更し ない限りどのようにでも実施することができる。例えば、図示の実施の形態では 、Ｌ型継手や直管継手を介して、上水道管に仮止水栓を取り付けているが、上水 道管の端部に仮止水栓を直接取り付けることもできる。The present invention has been described above based on the embodiments of the drawings. However, the present invention is not limited to the above-described embodiments, and is not limited to the embodiments described in the claims of the utility model unless the configuration is changed. Can be implemented as well. For example, in the illustrated embodiment, the temporary stop cock is attached to the water supply pipe via the L-shaped joint or the straight pipe joint, but the temporary stop tap may be directly attached to the end of the water supply pipe. it can.
【００３１】[0031]
以上要するに本考案によれば、建築物の建築途中における上水道管の通水試験 中、水圧の掛かった水道水は止水用隔壁によって止水され、螺子部分からの漏水 も嵌合筒部のシール材が面取部の斜面に密着して確実に防止される。また、面取 部の斜面によりシール材の外方への広がり変形が防止される。 In summary, according to the present invention, during the water flow test of the water supply pipe during the construction of the building, the tap water under water pressure is stopped by the partition wall for water stoppage, and the leakage from the screw part also seals the fitting cylinder part. The material adheres firmly to the slope of the chamfer and is reliably prevented. Further, the slope of the chamfer prevents the sealing material from spreading outward and deforming.
【００３２】 一方、嵌合筒部の雄螺子部とプラグ部との間には押圧嵌入部が形成されていて 螺子部とプラグ部との連続性が絶たれているので、ノッチ現象が生じにくくなり 、外部からの衝撃が螺子部の一点に集中することがないため、プラグ部と嵌合筒 部との連続部分での折損が確実に防止され、リング状のシール材は外部から衝撃 が生じた場合のクッションとしても機能し、衝撃を緩衝して折損が確実に防止さ れる。On the other hand, since the press fitting portion is formed between the male screw portion and the plug portion of the fitting tubular portion and the continuity between the screw portion and the plug portion is broken, the notch phenomenon is unlikely to occur. Since the external impact does not concentrate on one point of the screw part, breakage at the continuous part of the plug part and the fitting cylinder part is reliably prevented, and the ring-shaped sealing material receives external impact. It also functions as a cushion in the event of a shock, cushioning shocks and reliably preventing breakage.
