  FIGS. 1 to 3 show Embodiment 1 of the present invention, and FIG. 1 shows a joining portion of two polyethylene pipes 1 and 2 to be joined and a socket 5 which is a joint part. (Referred to as “resin pipe”) 1 and 2 are formed at the joint ends of 1 and 2, and the socket 5 is a synthetic resin cylindrical body having the same inner diameter as the outer diameter of the mouth 3, The receiving ports 4 and 4 are formed, and a locking projection 6 for restricting the fitting position of the differential port 3 is provided at the center of the inner peripheral surface.

  One or more (three in the illustrated example) annular groove 7 and one or more annular grooves 7 extending in the axial direction and intersecting the annular groove 7 are formed on the outer peripheral surfaces of the outlets 3 and 3 of the two resin tubes 1 and 2. A plurality of (four in the illustrated example) concave grooves 8 are provided. On the other hand, on the inner peripheral surfaces of the sockets 4 and 4 of the socket 5, an annular groove 9 and a concave groove 10 corresponding to the annular grooves 7 and the concave grooves 8 of the differential ports 3 and 3 are provided. When the joint 4 is fitted to the opening 4 and is brought into contact with the locking projection 6, the annular groove 7 and the annular groove 9 face each other, and the outer peripheral surface of the differential 3 and the opening end of the receiving opening 4. When the position marks (not shown) provided in the are combined, the groove 8 and the groove 10 are set to face each other. As for the cross-sectional shapes of the annular groove 7 and the annular groove 9 and the concave groove 8 and the concave groove 10, a semicircular shape, a triangular shape, a rectangular shape, and other various shapes can be adopted as illustrated in FIG.

When fitted in a predetermined position that contacts the stop projection 6, the annular groove 7 and the annular groove 9 face each other, and a position mark (not shown) provided on the outer peripheral surface of the differential port 3 and the opening end of the receiving port 4 is provided. When combined, the concave groove 8 and the concave groove 10 are held at positions facing each other, and the fluid fillers 21 filling the annular grooves 7 and the annular grooves 9 facing each other are mixed with each other and are opposed to each other. The resin-based filler 21 having fluidity filled in the concave groove 8 and the concave groove 10 is mixed with each other. If both the resin pipes 1 and 2 and the socket 5 are held in this state, the resin-based filler 21 mixed with the annular groove 7 and the annular groove 9 opposed to each other and the groove 9 and the groove 10 are mixed. The filled resin-based filler 21 is naturally cured with the passage of time, and becomes a cured filler 22 that fills the annular groove 7 and the annular groove 9 and the concave groove 8 and the concave groove 10 that face each other. And the shear strength which resists the tensile load which acts on the axial direction of both the resin pipes 1 and 2 and the rotational stress which acts on the circumferential direction is obtained by the separation preventing action of the completely hardened filling 22.

Then, as shown in FIG. 5, the differential port 3 of both the resin pipes 1 and 2 is fitted into both the receiving ports 4 and 4 of the socket 5 so that the annular groove 7 and the annular groove 9 face each other, and the concave groove In a state where the groove 8 and the concave groove 10 are held at opposite positions, a room temperature curable resin filler 21 having adhesiveness and fluidity is injected through the injection hole 11, and as shown in FIG. The filling material 21 is poured until it overflows from all the injection holes 11 so that the annular groove 7 and the annular groove 9 facing each other and the concave groove 8 and the concave groove 10 facing each other are filled. When the resin tubes 1 and 2 and the socket 5 are held in the fitting position in this filled state, the resin-based filler 21 filled in the annular groove 7 and the annular groove 9 and the concave groove 8 and the concave groove 10 facing each other, It hardens spontaneously with the passage of time, and becomes a hardened filling 22 filled in the annular groove 7 and the annular groove 9 and the concave groove 8 and the concave groove 10 which face each other. And, the point that the shear strength against the tensile load acting in the axial direction of both the resin tubes 1 and 2 and the rotational stress acting in the circumferential direction can be obtained by the separation preventing action of the completely cured cured filler 22 is implemented.
