Regarding the installation structure, more specifically, regarding the installation structure of a split T-shaped pipe when the existing fluid pipe is used as a valve box of a water control valve with no water interruption, it is particularly effective for use with brittle pipes such as asbestos pipes. It is. Here,
"Uninterrupted water supply" is not limited to just water, but is a general term for carrying out construction work while the flow of gases and liquids is not stopped by a pre-installed stopper (main stopper).

した。 The applicant previously filed Japanese Patent Application No. 56-70653, Utility Application No.
No. 56-138272 discloses a so-called method in which a hole is drilled in an existing fluid pipe without water interruption, a water control valve body is inserted into the hole in the existing fluid pipe, and the water control valve body is pressed against the inner wall of the existing fluid pipe to stop water. A water control valve device with continuous water insertion was proposed.

る。 An example is shown in FIG. Here, P is the existing fluid pipe, Q is the hole drilled at the position where the water control valve of the fluid pipe P is attached, 1 is the split T-shaped pipe, and V is the valve cover 6, valve stem 7, and valve body. This is a water control valve consisting of 8 parts.

体８Ａは弁棒７のねじ部７１に螺合され、弁棒７
の回転により弁棒７に沿つて上下動させられる。 The split T-shaped tube 1 has a trunk tube portion 11 and a branch tube portion 12, and the trunk tube portion 11 is usually formed into two halves.
The flanges 11a facing each other are tightened with fasteners 11b such as bolts and nuts, and the inner surface of the body-shaped tube portion 11 is pressed against the outer surface of the fluid pipe P and fixed. Further, a socket portion 13 and a flange-shaped collar portion 14 are formed at the end of the branch pipe portion 12 . Further, the valve cover 6 is formed with a socket part 61 that is inserted into the socket part 13, and after the socket part 61 is fitted into the socket part, it is fixed with a fixing flange ring 91 and a fastener 92. Ru.
The valve body 8 consists of a valve body 8A and a rubber plate 8B, and the valve body 8A is screwed into the threaded portion 71 of the valve stem 7.
It is moved up and down along the valve stem 7 by the rotation of the valve.

多用される傾向にある。 According to this, since it is used as the valve box of the water control valve V into which the existing fluid pipe P is inserted and installed, there is no need to prepare a new valve box, which saves materials and provides a compact water control valve. In addition, it has the advantage of improving drilling workability due to the small cross-section of the hole, and has been increasingly used in recent years.

になる。 However, on the other hand, since the lower part of the inner wall of the existing fluid pipe P directly becomes the valve seat, the valve body and valve seat do not fit well and there is a problem with water-stopping properties. is used, and it is necessary to forcefully press this rubber body against the inner wall of the fluid pipe. As a result, the installed water control valve has to be operated by strongly tightening the valve stem which is interlocked with the valve body in order to shut off the water.
そして、この反力が既設流体管の外周に固定さ
れた割りＴ字管ひいては流体管に作用することに
なる。 This reaction force then acts on the split T-shaped pipe fixed to the outer periphery of the existing fluid pipe, and ultimately on the fluid pipe.

ればこの問題が生じることは同様である。 As a result, in so-called brittle pipes where the existing fluid pipes are made of asbestos pipes, other brittle materials such as ceramic pipes, glass pipes, etc., damage such as cracking or breakage is observed in the vicinity of the split T-shaped pipes due to this acting force. It turns out. In other words, in asbestos pipes, not only is the material itself brittle, but also the uneven surface formed on the outer circumferential surface during the forming process collides with the inner surface of the split T-shaped pipe, causing concentrated stress that exceeds the allowable stress at that part. It is considered that the above-mentioned damage is caused by various causes, such as the occurrence of the perforation Q and the reduction in the strength of the tube due to the perforation Q. Note that this problem also occurs in tough fluid pipes such as steel pipes and cast iron pipes if their cross-sectional strength is insufficient.
そこで、本考案はこの技術的問題を解消すべく

ことなく伝わることになる。 With the above configuration, the present invention has the following effects when the water control valve is operated. In other words, the acting force generated by tightening the water control valve is transmitted to the split T-shaped pipe via the valve cover, but this force is evenly distributed to the fluid pipe through the solidified resin, that is, stress concentration occurs. It will be conveyed without any trouble.

In other words, the solidified resin that is injected and filled is a fluid at the time of injection, so it adapts well to the irregularities on the outer surface of the fluid pipe.
After solidification, uneven surfaces are pressed uniformly and there is no stress concentration. Therefore, damage to the fluid pipe due to concentrated loads is eliminated, and the present invention is effectively applied to brittle pipes, and the applications of fluid pipes into which water control valves are inserted are expanded. At the same time, a strong tightening force of the water control valve is obtained, which improves water stoppage performance.
