本考案は、径寸法が異なる大径管体と小径管体
とを接続するための管継手に関する。[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a pipe joint for connecting a large diameter pipe body and a small diameter pipe body having different diameter dimensions.
（従来の技術とその課題）
一般に、径寸法が異なる規格サイズの管体同志

と小径の合成樹脂管とを接続する場合には、規格
化された異径ソケツトがない。(Prior Art and Its Problems) Generally, when connecting pipe bodies of different standard sizes with different diameter dimensions, a pipe joint called a different diameter socket is used. However, when connecting pipes with varying diameters, such as a large diameter concrete pipe and a small diameter synthetic resin pipe, there is no standardized socket with different diameters.
このため、従来はコンクリート管内に合成樹脂

て、通水不良が発生することがあつた。 For this reason, in the past, the end of a synthetic resin pipe was inserted concentrically into a concrete pipe, and the gap between the inner peripheral surface of the concrete pipe and the outer peripheral surface of the synthetic resin pipe was filled with a sealing material such as concrete or mortar. It was connected. However, in the case of this connection, since the inner part of the gap is not closed, the sealing material sometimes enters the concrete pipe from the tip of the synthetic resin pipe, resulting in poor water flow.
本考案は、かかる従来管継手の欠点を解消した

材で包囲したことを特徴とするものである。(Means for Solving the Problems) In the pipe joint of the present invention, the outer periphery of the end of the small-diameter tube inserted in contact with the bottom surface of the inner circumference of the large-diameter tube almost touches the inner circumferential surface of the large-diameter tube. A flange is provided to protrude, and a sealing material is pressed into the gap between the inner circumferential surface of the large diameter tube and the outer circumference of the small diameter tube, and the outer circumference of the small diameter tube protruding from the end of the large diameter tube is filled. It is characterized in that the surface is surrounded by a sealing material over a predetermined width.

面一となる。(Function) When the pipes are connected, the flange protruding from the outer periphery of the end of the small diameter pipe prevents the sealing material from entering the large diameter pipe. Furthermore, since the small diameter tube is connected in contact with the inner circumferential bottom surface of the large diameter tube, the inner circumferential bottom surfaces of both tubes are substantially flush with each other.
（実施例）
以下、本考案の実施例を図面にて詳細に説明す

In the figure, reference numeral 1 denotes a large-diameter pipe such as a concrete pipe or ceramic pipe, and 2 a small-diameter pipe made of synthetic resin such as vinyl chloride, which has an outer diameter smaller than the inner diameter of the large-diameter pipe 1.
小径管体２は一端部に拡径受口２１を有し、そ
の他端部外周に鍔体２２が突設されている。 The small-diameter tube body 2 has an enlarged-diameter socket 21 at one end, and a collar body 22 protrudes from the outer periphery of the other end.

うに形成する。 The flange body 22 is formed into a shape such that when the small diameter tube 2 is inserted into the large diameter tube 1 while being in contact with the inner circumferential bottom surface of the large diameter tube 1, the flange body 22 comes into almost contact with the inner peripheral surface of the large diameter tube 1. For example, when connecting a perfectly circular small-diameter tube 2 to an oval-shaped large-diameter tube 1 as shown in FIG. Then, the flange body 2
The outer circumferential edge of the large-diameter tube body 1 is formed so as to be substantially in contact with the inner circumferential surface of the large-diameter tube body 1.

とよい。 In addition, in FIG. 1, the collar body 22 that protrudes in a direction perpendicular to the tube axis of the small diameter tube body 2 is illustrated by a solid line, but
This flange body 22 may be inclined in a tapered shape as shown by the broken line in the figure. Furthermore, the flange body 22 is not limited to one that projects integrally with the small diameter tube body 2, but may be formed separately and joined to the outer periphery of the end portion of the small diameter tube body 2 using an adhesive or the like. In addition, the outer periphery of the end of the small-diameter tube 2 inserted into the large-diameter tube 1 is subjected to surface roughening treatment 24 such as texturing or adhesion of sand, and a tapered chamfer is formed on the inner surface of the tube end. It is a good idea to do step 23.

固に接続される。 In the present invention, the end of the small-diameter tube 2 described above is inserted into the large-diameter tube 1, and the deep part of the gap between the inner circumferential surface of the large-diameter tube 1 and the outer circumferential surface of the small-diameter tube 2 is inserted into the large-diameter tube 1. After closing the gap with the flange body 22, a sealing material such as cement or mortar is forced into the gap. Then, when the outer peripheral surface of the small diameter tube 2 protruding from the end of the large diameter tube 1 is further surrounded with a sealing material, the small diameter tube 2 is attached to the inner bottom surface of the large diameter tube 1 as shown in FIG. A strong connection is established when the two are in contact with each other.

とがない。(Effects of the invention) As detailed above, the pipe joint of the present invention has a flange protruding from the outer periphery of the end of the small-diameter pipe that almost contacts the inner circumferential surface of the large-diameter pipe. Since the deep part of the gap between the circumferential surface and the outer circumferential surface of the small-diameter tube body is closed with the collar body and then the sealing material is forced and filled, there is no intrusion of the sealant into the large-diameter tube body. Furthermore, since the small diameter tube is connected in contact with the inner circumferential bottom surface of the large diameter tube, the inner circumferential bottom surfaces of both tubes are substantially flush with each other, so that poor water flow does not occur.
