い。DETAILED DESCRIPTION OF THE INVENTION Generally, in order to reinforce a plastic pipe joint, a metal pipe joint is manufactured and the inside of the joint is lined with plastic by injection molding. However, in this case, not only is the manufacturing cost of the metal pipe joint added, making it expensive, but also the plastic lining shrinks during hardening, so it does not necessarily come into close contact with Itg.

法が；辱られる。In the present invention, two outer peripheral reinforcing plates 1 and 1' having 7 rungs 2, 3.2' and 3' are placed in an injection mold and a plastic pipe fitting 8 is placed between them. Two outer reinforcing plates made by injection molding! and 1', the two outer peripheral reinforcing plates 1 and 1' can be easily manufactured by simply press-molding metal plates, and these can be assembled into a mold. Since the plastic pipe joint 8 is formed on the upper and lower molds by injection molding, the molten plastic is deposited on the entire back surface of the outer peripheral reinforcing plates 1 and 1. At this time, if an attaching protrusion 7 is provided in the welded amount, this bonding will be further strengthened. Since the outer peripheral reinforcing plate 1 and 1' are provided with flange parts 2, 3, 2' and 3', the melted plastic enters between these parts, expanding the fusion area and strengthening the bonding force. Ru. Furthermore, after injection molding, the upper and lower outer periphery reinforcement [1 and 1' are pressed together and joined with point welding 4 or rivets within the range of the plastic's soft carbon temperature to prevent shrinkage during hardening of the plastic; Avoidable, outer peripheral reinforcement plate 1 &
1) A strong reinforcing joint is created in which the plastic pipe joint 8 and I' are completely in contact with each other. At this time, by inserting a standard cylindrical gauge into the g-junction socket 11, performing the above operations, and removing the standard cylindrical gauge after hardening, the method of making a highly accurate socket is violated.
