Claims

[Scope of utility model registration request]

One end of the terrastic tube is fitted into a cylindrical metal core 1 whose outer circumference is tapered and has one to several inwardly directed serrated blades on the tapered surface, and whose other end forms a flange, A cylindrical sleeve 6 having a tapered inner surface, a protrusion, and a step on the outer side is further inserted into a portion of the tapered plastic tube thus formed. On the other hand, symmetrically connect another plastic tube 2' to the metal core 1' with the same structure,
Further, a sleeve 6' is attached to a part of the outer taper, and the sleeve 6' is opposed to each other with an elastic packing 5 interposed between them, and the sleeve step part is connected in the direction of the flange surface using two flanges 3, 3' and several bolts. A joint structure for a plastic pipe, characterized in that an intermediate elastic packing is crimped onto a flange surface by a screw that is tightened, and a tapered core and a pipe are tightly and firmly crimped and gripped with an outer sleeve.
