着する構成がとられている。 To connect a main pipe and a branch pipe, as shown in Fig. 1, a mounting hole 2 is opened at a predetermined location of the main pipe 1, and a branch pipe joint 3 is brought into contact with the mounting hole 2 as shown in Fig. 2. Alternatively, a structure is adopted in which the branch pipe 5 is fixed with a bonding material 4 and inserted into the branch pipe joint 3 which is thus attached to the main pipe 1.

下すると云う欠点があつた。 Conventionally, this type of branch pipe joint 3 has a structure in which a socket part 32 with a ring groove 31 formed at its tip is disposed in the upper part, and an insertion part 34 with a skirt part 33 attached in the lower part. In the structure, when the branch pipe joint 3 is attached to the main pipe 1 having a smaller radius of curvature than the radius of curvature of the skirt part 33, the outer periphery of the main pipe 1 and the skirt part 33 do not come into close contact with each other as shown in FIG. It is formed. Therefore, when fixing the branch pipe fitting 3 with mortar or bonding material, the mortar or bonding material may enter the main pipe 1 through the attachment hole 2 of the main pipe 1, and the strength of the attachment between the main pipe 1 and the branch pipe fitting 3 may decrease. Then, there was a drawback.

である。 The purpose of the present invention is to improve the above-mentioned drawbacks and provide a branch pipe joint with a skirt that can be applied to main pipes of various sizes without forming gaps. In a branch pipe joint having an insertion section with a section attached thereto, a flexible sheet is attached to the upper or lower surface of the skirt section, and both side edges of the flexible sheet are made to protrude from both side edges of the skirt section. The main points are as follows.

体を材料とする。 The present invention will be explained with reference to an embodiment shown in FIG. 4 and subsequent figures. A socket part 32 in which a ring groove 31 is formed is arranged in the upper part of the branch pipe joint 3 shown in the figure, and an insertion part 34 to which a skirt part 33 is attached is arranged in the lower part. Note that the socket portion 32 is formed in a tapered shape that increases in diameter toward the bottom so that the connection of the branch pipe into which it is inserted has flexibility. A flexible sheet 35 is attached to the upper surface of the skirt portion 33 by adhesive or welding, and both side edges 35A, 35A of the flexible sheet 35 are attached to the upper surface of the skirt portion 33.
It is made to come out from both side edges 33A, 33A. The upper surface of both side edges 33A, 33A of the skirt portion 33 is the fourth
Form a gently sloping rounded corner as shown in the figure.
Both side edges 35 of the flexible sheet 35 along the rounded corner
A, 35A is directed downward. The branch pipe joint 3
is generally polyvinyl chloride, polyethylene, polypropylene, acrylonitrile-butadiene.
The flexible sheet 35 is made of hard plastic such as styrene resin or glass fiber reinforced plastic.
is made of soft plastics or rubbers such as soft polyvinyl chloride, soft polyurethane, styrene-butadiene rubber, acrylonitrile-butadiene rubber, ethylene-propylene rubber, natural rubber, recycled rubber, or foams of these plastics or rubbers.

ンリング７を介して分岐管５を挿着する。 In the above configuration, as shown in FIG. 6, a mounting hole 2 is opened in the main pipe 1 made of plastic, concrete, ceramics, iron, etc., and the insertion part 34 of the branch pipe joint 3 is inserted into the mounting hole 2. 33 on the outer periphery of the main pipe 1, the branch pipe joint 3 is stably supported at the position of the mounting hole 2, and the skirt portion 3
The side edges 35A, 35A of the flexible sheet 35 protruding from the side edges 33A, 33A of the flexible sheet 3 are bent so as to fit closely to the outer periphery of the main pipe 1, and as shown in FIG. Fix it. Although not shown, it may be fixed with a wire.
After fixing with wire, adhesion and bonding properties are further improved by fixing with mortar or a bonding material. Next, the branch pipe 5 is inserted through the packing ring 7 inserted into the ring groove 31 of the socket part 32.

５Ａ，３５Ａが撓み易くなる。 In addition to this embodiment, a flexible sheet 35 may be attached to the lower surface of the skirt portion 33, for example, as shown in FIG. Also, the width of the skirt portion 33 is the same as that of the branch pipe joint 3.
If the outer diameter is equal to or smaller than the outer diameter of the insertion portion 34 of the flexible sheet 35, the side edges 3 of the flexible sheet 35
5A and 35A become easily bent.

分岐管継手との取付強度が向上する。 Since the present invention has the above-mentioned configuration, in a branch pipe joint in which a socket part is arranged at the upper part and an insertion part with a skirt part attached at the lower part, the skirt part allows the branch pipe joint to be stably inserted into the mounting hole of the main pipe. By bending both side edges of the flexible sheet that is supported and protrudes from both side edges of the skirt portion, it is possible to bring the both side edges into close contact with the outer periphery of main pipes of various sizes. Even when fixing with mortar or bonding material, intrusion of the mortar or bonding material into the main pipe from the attachment hole of the main pipe is prevented, and the attachment strength between the main pipe and the branch pipe joint is improved.
