はかなりの熟練を要す。 For sewage piping and gray water piping, for example, as shown in Figure 1, large diameter pipes made of synthetic resin (hereinafter referred to as socket pipes) are used.
1 and a large-diameter inlet tube (hereinafter referred to as an inlet tube) 2 made of the same material are inserted and joined via a packing 3. However, the socket part 4 of the socket pipe 1 has a larger diameter than the main pipe part in order to create an insertion space for the socket part 5 of the socket pipe 2 and the packing 3, and is easy to manufacture. The tapered portion 4' is formed from this point. Therefore, if you look at the joint state of the pipes, a recess 6 as shown in Figure 1 is formed, but since this recess 6 impairs the smoothness of the inner surface of the pipe, it not only increases water flow resistance but also In particular, in sewage water containing a large number of foreign substances, the foreign substances tend to get stuck in the recess 6, and the accumulation of foreign substances impairs the flow of the sewage. Therefore, conventionally, a spacer ring or the like is attached to the recess 6 to align the open side of the recess 6 with the inner surface lines of the socket pipe 1 and the inlet pipe 2 to minimize water flow resistance and prevent foreign objects from getting caught. Efforts are being made to prevent this. On the other hand, when inserting and joining large-diameter pipes, since these are quite heavy objects, the end face 5a of the socket pipe 1 on the socket side and the back face of the socket pipe 2 on the socket side are used as shown in FIG. Engagement jigs 7 and 8 are arranged on each of 6a, and both engagement jigs 7,
The insertion part 5 is inserted into the socket part 4 by pulling the wire 9 stretched between the wires 8 with a puller 10 or the like. That is, when performing the joining work using a puller, such an engagement jig 8 must be placed on the socket-side inner surface 6a, and therefore a spacer ring cannot be attached to that location in advance. For this reason, conventionally, after insertion and joining, a worker enters through the opening on the socket 4 side or the insertion tube 5 side, carries in the spacer ring 11, and attaches it to the recess 6 as shown in FIG. . That is, the spacer ring 11 used in this case is a flexible ring body that has approximately the same diameter as the connecting pipe and is partially cut so that the diameter can be reduced as shown in the figure. In this case, the diameter is reduced as shown in the figure, and the reduced diameter is released at the recess 6 position, and the ring shape is restored and installed, and the wedge member 12 is inserted between the ring cut surfaces 11a, 11a. It is press-fitted to prevent the spacer ring 11 from coming off. However, when handling such a spacer ring, there are the following disadvantages. The first point is that the resilient ring cannot be carried into the recess 6 unless it is contracted in diameter, but especially when the pipe is long, it is necessary to maintain the contracted diameter state for a long period of time. It requires excessive effort to transport. The second point is that the ring cannot be installed stably unless the wedge member 12 is press-fitted, and furthermore, it requires considerable skill to press-fit the wedge member into a conduit with limited work space. .

である。 In other words, the structure of the present invention that achieves the above purpose is as follows.
The spacer ring is composed of a curved member divided into at least two parts, and at least the butt joint end of each curved member is arranged along the tapered enlarged diameter inner circumferential surface of the socket and flush with the inner circumferential surface of the socket. The gist is to form a thick part with a triangular cross-section such that the cross section is triangular, and to provide an engaging part between the joining ends at the joining end, and to connect each curved member with these engaging parts. It is.

Further, the curved members 13a, 13b, and 13c have inner surfaces curved parallel to the tube axis and have the same curvature as the inner surface of the straight tube portions of the socket tube 1 and the inlet tube 2.
On the other hand, the outer peripheral surfaces of the engaging portions 14a, 15a, .

宜変更して実施されることが望ましい。 Therefore, the loading and mounting of the spacer ring 11 is carried out as follows. First, the spacer ring 11 is divided to separate the curved members 13a, . At this time, the curved material 13a etc. are packed into small pieces, so
It is extremely easy to carry. Then, while applying the brought curved material 13a... to the concave portion 6 in order, each engaging portion 14a and 15b, 14b and 15c,
14c and 15a are engaged, respectively. The curved members 13a, 13b, and 13c thus engaged are pressed against each other within the recess 6 and are maintained in a bridge shape.
The bending member 13a is prevented from disassembling or coming off as a ring, and a stable mounting state can be obtained. The shape of the engaging portion may be various, such as a circular engaging protrusion 16a or a polygonal engaging protrusion 16b, as shown in FIGS. 6 and 7, for example. FIG. 8 shows another embodiment of the curved member, in which a rib 18 is provided on one side of the curved member 13a to make the cross section L-shaped, thereby increasing the strength of the curved member. In addition, the number of divisions of curved materials is, for example, the nominal diameter is 600 to 1350 mm.
2 divisions for φ, 3 divisions for 1500 to 2000mmφ, 2200
For mmφ or more, it is preferable to divide the pipe into four parts, changing it appropriately depending on the diameter of the pipe.

It has now become possible to prevent this. Also, in the water resistance test after piping, the spacer ring makes the inner surface shape extremely simple, so the structure and installation of the water tightness test equipment can be simplified, and the amount of water used for the water resistance test can be reduced.
