【考案の詳細な説明】
本考案は、管の接合に用いられるパツキンに関
する。[Detailed Description of the Invention] The present invention relates to a packing used for joining pipes.
詳しくは、ヒユーム管等の本管の側面に穴を穿
ち、この穴の中へ枝管を挿入するような管接合部
のパツキンに関する。 Specifically, it relates to a gasket for a pipe joint where a hole is bored in the side of a main pipe such as a humerous pipe and a branch pipe is inserted into the hole.
下水道などで、本管に枝管を接合する箇所は、
漏水しやすく、種々の対策が考えられている。例
えば、有機系及び／又はセメント系のパテを接合
部に適用する方法、ゴム状物質のパツキンを接合
部に装着する方法等がある。しかし、パテを用い
る方法は、作業性が悪く、かつ止水も完全ではな
いので、望ましいものではない。一方、ゴム状物
質からなるパツキンを接合部に装着する方法は、
作業性は多少改善されるものの、止水が完全であ
るとは言えない。 In sewers, etc., where branch pipes are joined to the main pipe,
Water leaks easily, and various countermeasures have been considered. For example, there is a method of applying organic and/or cement-based putty to the joint, a method of attaching a rubber-like substance to the joint, and the like. However, the method using putty is not desirable because it has poor workability and does not completely stop water. On the other hand, the method of attaching a gasket made of rubber-like material to the joint is
Although workability is improved to some extent, it cannot be said that water stoppage is complete.
すなわち、従来のゴムパツキンは、その断面構
造を第１図に示すように、本管１に穿たれた穴２
に、パツキン４を介して、枝管３を挿入、固定す
るもので、パツキン４の、本管１に挿入される管
部の外面が凹凸形状となつているものであり、該
パツキン４は枝管３の先端部に装着して使用され
るものであつた。 That is, the conventional rubber gasket has a cross-sectional structure as shown in Fig. 1, with a hole 2 drilled in a main pipe 1.
The branch pipe 3 is inserted and fixed through the packing 4, and the outer surface of the pipe portion of the packing 4, which is inserted into the main pipe 1, has an uneven shape. It was used by being attached to the tip of the tube 3.
これは、本管１に穿たれた穴２の径が現場作業
のため統一的に決まらず、その径の差をパツキン
でカバーするためであつた。しかしながらパツキ
ン管部の外側がこのように凹凸状であると、現場
で穿たれた穴２の側面も粗面となるため密着性が
良くなく止水性が低下することが避けられなかつ
た。 This was because the diameter of the hole 2 drilled in the main pipe 1 was not uniformly determined due to on-site work, and the difference in diameter was to be covered with a gasket. However, if the outside of the packing tube is uneven in this way, the side surface of the hole 2 drilled at the site will also have a rough surface, resulting in poor adhesion and a decrease in water-stopping properties.
本考案は、上記の問題を改善することを目的と
するものであつて、本考案のパツキンは、本管１
の外周面によつて係止されるつば部６と、本管１
の内部に挿入されうる水膨潤性物質からなる管部
５からなり、かつ該管部の内面が凹凸状となつて
いることを特徴とする。 The purpose of the present invention is to improve the above problem, and the packing of the present invention has a main
a collar portion 6 that is locked by the outer peripheral surface of the main pipe 1;
It is characterized in that it consists of a tube section 5 made of a water-swellable material that can be inserted into the interior of the tube, and that the inner surface of the tube section is uneven.
本考案の一実施態様を示す断面構造を第２図に
示す。 A cross-sectional structure showing one embodiment of the present invention is shown in FIG.
本考案のパツキンのつば部は本管１の外周面に
よつて係止できるようにリング状に形成され、管
部と一体に形成されている。管部内面に設けられ
た凹凸は断面波形状その他適当な形状でよく、凹
凸の深さは径に合せて適宜所望の大きさに決める
ことができる。 The collar of the packing according to the present invention is formed into a ring shape so that it can be locked by the outer peripheral surface of the main pipe 1, and is formed integrally with the pipe part. The unevenness provided on the inner surface of the tube portion may have a corrugated cross section or any other suitable shape, and the depth of the unevenness can be appropriately determined to a desired size according to the diameter.
かかる本考案のパツキン４は、本管１の穴２に
あらかじめ装着しておき、そこに枝管３を差し込
んで接合することができるので作業性が大幅に向
上できる。 The packing 4 of the present invention can be installed in advance in the hole 2 of the main pipe 1, and the branch pipe 3 can be inserted therein and joined, so that workability can be greatly improved.
本考案のパツキンは、穴の径のバラツキを、管
部内面の凹凸部で吸収することができ、また、管
部内面に接触する枝管は、塩ビ管、陶管、ヒユー
ム管等外面がなめらかなものであるから、止水性
が向上する。一方管部外面と穴の側面の接触面積
が大きくなるので、止水面も広くなり、止水性が
向上するとともに固定もしやすくなる。 The packing of the present invention can absorb variations in hole diameter with the uneven parts on the inner surface of the tube, and branch pipes that come into contact with the inner surface of the tube have smooth outer surfaces such as PVC pipes, ceramic pipes, and humid pipes. This improves water-stopping properties. On the other hand, since the contact area between the outer surface of the tube and the side surface of the hole becomes larger, the water-stopping surface also becomes wider, improving water-stopping properties and making it easier to fix.
本考案のパツキンは、管部が水膨潤性物質から
なつているので、止水性が非常に優れている。 The seal of the present invention has extremely excellent water-stopping properties because the tube portion is made of a water-swellable substance.
管部を水膨潤性物質で形成したパツキンは、漏
水等の水が水膨潤性物質部分に接触すると膨張
し、間隙を塞いで密封するので、管接合後、接合
部の変形等があつても止水性は低下しない。 The gasket, whose pipe portion is made of a water-swellable material, expands when water such as water leaks comes into contact with the water-swellable material, closing the gap and sealing it, so even if the joint portion deforms after the pipe is joined, it will not be affected. Water stop property does not decrease.
上記水膨潤性物質としては、例えば、ビニル
系、アクリル系の単一重合体もしくは共重合体、
ポリウレタン系重合体、セルロース、デンブン又
はその変性物、架橋物等が挙られる。中でも好ま
しいものは水膨潤性ポリウレタン含有可撓性物質
であり、特に好ましいのは、水膨潤性ポリウレタ
ンと天然ゴム、合成ゴム、もしくは再生ゴム等の
混合物からなる可撓性物質である。 Examples of the water-swellable substance include vinyl-based or acrylic-based homopolymers or copolymers;
Examples include polyurethane polymers, cellulose, starch, modified products and crosslinked products thereof. Among these, preferred are flexible materials containing water-swellable polyurethane, and particularly preferred are flexible materials comprising a mixture of water-swellable polyurethane and natural rubber, synthetic rubber, recycled rubber, or the like.
以上の如く構成された本考案のパツキンは止水
性良好で、実用上多大の価値があるものである。 The packing of the present invention constructed as described above has good water-stopping properties and is of great practical value.
