Abstract

PURPOSE: To butt-joint hard viny1 tubes airtightly and firmly by inserting cylindrical wedges into gaps between a cylindrical joint outer tube and hard viny1 tubes inserted to it.
CONSTITUTION: A joint outer tube 1 and wedges 3 are passed through on hard viny1 tubes 5 to be connected, adhesive is applied on the outer surfaces of the wedges 3 and on the outer surfaces of the connected parts of the hard viny1 tubes 5, then the joint outer tube 1 is moved to the connected part, the wedges 3 are pushed into the gaps between the joint outer tube 1 and the hard viny1 tubes 5 from both directions to fix the joint outer tube 1 and the hard viny1 tubes 5. The wedges 3 are provided with slits 4 from both ends alternately, therefore, the radial contraction of the wedges 3 can be performed easily over the whole length by the action of the tapered parts 2 of the joint outer tube 1 as the wedges 3 are pushed into the joint outer tube 1 and thus the inner surfaces of the joint outer tube 1 and the outer surfaces of the wedges 3 stick very tightly with each other and at the same time, the inner surfaces of the wedges 3 and the outer surfaces of the hard viny1 tubes 5 also stick very tightly with each other.
