【考案の詳細な説明】
本考案は特に下水管等の排水管として使用される断面形
状が卵形の管の管継手に関するものである。[Detailed Description of the Invention] The present invention particularly relates to a pipe joint for a pipe having an oval cross-sectional shape and used as a drain pipe such as a sewage pipe.
断面形状が卵形の管を排水管として敷設するにはこの管
の排水特性を発揮させるため卵形の頂部（尖った側の先
端部）が真下に向くようにして敷設する必要があるが、
管には製造時の歪や変形によるねじれがあり、特に硬質
塩化ビニル樹脂を押出成形して製造したものでは製造後
の変形によるねじれがあり、両受口を有する継手で連結
配管していくと、卵形の管の頂部が真下に向かないよう
になる。When laying a pipe with an oval cross-sectional shape as a drainage pipe, it is necessary to lay it so that the top of the oval (pointed end) faces straight down in order to maximize the drainage characteristics of the pipe.
Pipes may be twisted due to distortion or deformation during manufacturing, especially those manufactured by extrusion molding of hard PVC resin, which may be twisted due to deformation after manufacturing. , the top of the oval tube no longer points straight down.
従来はこの管のねじれを施工時に杭を打込んで矯正して
いたが手間がかかる欠点があった。Conventionally, this twist in the pipe was corrected by driving piles during construction, but this had the disadvantage of being time-consuming.
本考案は上記の欠点を継手を改良することにより解消し
たものであって、その要旨は、断面形状が卵形の管の一
端部に受口、他端部にボルト孔を有するフランジが形成
されてなる２個の継手部材が、フランジ同士を対面させ
てボルトとナツトで締付けて接続されており、前記ボル
ト孔は卵形の管の頂部に設けられる円孔とこの円孔を中
心とする円周方向の長孔とからなることを特徴とする管
継手に存する。The present invention solves the above-mentioned drawbacks by improving the joint, and its gist is that a tube with an oval cross-sectional shape is formed with a socket at one end and a flange with bolt holes at the other end. The two joint members are connected by tightening bolts and nuts with their flanges facing each other, and the bolt holes are connected to a circular hole provided at the top of the oval tube and a circle centered around this circular hole. The present invention resides in a pipe joint characterized by comprising a circumferential elongated hole.
次に、本考案を図面を参照して説明する。Next, the present invention will be explained with reference to the drawings.
第１図は本考案の継手部材の一例を示すもので１．１は
断面形状が卵形の管で、一端部には受口２が形成され、
他端部にはフランジ３が形成されている。FIG. 1 shows an example of the joint member of the present invention. 1.1 is a tube with an oval cross-sectional shape, and a socket 2 is formed at one end.
A flange 3 is formed at the other end.
受口２は接着剤で接続するものであっても、ゴムリング
を介して嵌挿するものであってもよい。The socket 2 may be connected with adhesive or may be inserted through a rubber ring.
フランジ３にはフランジ接続用のボルト孔４や穿設され
ており、ボルト孔４は管１の頂部（尖った側の先端部）
に穿設される円孔４１とこの円孔４１を中心とする円周
方向の長孔４２，４３．４４とからなる。The flange 3 has bolt holes 4 and holes for flange connection, and the bolt holes 4 are located at the top of the pipe 1 (the tip of the pointed side).
It consists of a circular hole 41 bored in the hole 41 and elongated holes 42, 43, and 44 extending in the circumferential direction around the circular hole 41.
長孔４２，４３．４４は円孔４１を中心とする円周に沿
う方向にはＳ′沿っていればよく、またその長さは円孔
４１を中心として一定角度となるようになされていれば
よい。The elongated holes 42, 43, and 44 only need to be along S' in the direction along the circumference with the circular hole 41 as the center, and their lengths should be set at a constant angle with the circular hole 41 as the center. Bye.
したがって円孔４１に近い長孔４２，４３の長さは遠い
長孔４４の長さより短かくてよい。Therefore, the lengths of the long holes 42 and 43 near the circular hole 41 may be shorter than the length of the long hole 44 that is far away.
長孔４４の長さは実用上２−位あればよい。Practically speaking, the length of the elongated hole 44 may be approximately 2 mm.
そして、本考案の管継手は断面形状が卵形の管を敷設す
る際、第２図に示すように接続する両方の管５，５の端
部に受口２を被嵌して取付られ、バッキングを介してフ
ランジ３，３のボルト孔４にポルｌ〜６を通してナツト
７で締付けて接続さる。When installing a pipe having an oval cross-sectional shape, the pipe joint of the present invention is installed by fitting the socket 2 into the end of both pipes 5, 5 to be connected as shown in FIG. The ports 1 to 6 are passed through the bolt holes 4 of the flanges 3 and 3 through the backing and are tightened with nuts 7 to connect.
フランジ３゜３を締付けるとき、長孔４２，４３，４４
となされたボルト孔４により接続する側の管５の頂部が
真下に向くように調節される。When tightening the flange 3゜3, use the long holes 42, 43, 44.
The bolt hole 4 is adjusted so that the top of the pipe 5 on the connecting side faces straight down.
本考案の管継手は上述した通りの構成であって、管の一
方の端部に受口、他方の端部にボルト孔を有するフラン
ジが形成されてなる２個の継手部材が、フランジ同士を
対面させて接続されるようになっているので、連結しよ
うとする２本の管の対面する端部に受口を被嵌して取付
け、対面するフランジをボルト締めして接続でき、しか
もボルト孔が管の頂部の円孔とこの円孔を中心とする円
周方向の長孔とからなるため、接続する双方の管の管底
となる頂部を合わせて接続する管の姿勢を正しく調節す
ることができる。The pipe joint of the present invention has the above-mentioned configuration, in which two joint members each having a socket at one end of the pipe and a flange having a bolt hole at the other end connect the flanges to each other. Since they are connected facing each other, the two pipes to be connected can be connected by fitting the sockets over the facing ends of the pipes and tightening the facing flanges with bolts. consists of a circular hole at the top of the tube and a long hole in the circumferential direction around this circular hole, so the posture of the connecting tubes must be adjusted correctly by aligning the tops, which are the bottoms of both tubes, to be connected. Can be done.
したがって管そのものにねじれがあっても接続部で調節
できるので、配管全体として排水特性が損われることの
ない配管施工が行える。Therefore, even if there is a twist in the pipe itself, it can be adjusted at the connection part, so piping construction can be performed without impairing the drainage characteristics of the pipe as a whole.
又、双方の継手部材のフランジに長孔が設けられている
ので、一方のフランジに設ける長孔の幅を短かくして、
フランジ同士のずらす幅を大きくでき、したがって、フ
ランジの幅を大きくしなくてもよい程度の長孔で接続す
る管の姿勢を正しく調整できる。Also, since elongated holes are provided in the flanges of both joint members, the width of the elongated hole provided in one flange can be shortened.
The width by which the flanges are shifted from each other can be increased, and therefore the posture of the pipes connected through the long holes can be adjusted correctly without increasing the width of the flanges.
