Corrugated Spiral Tube Fittings and Corrugated Spiral Tubes with Fittings and Methods for Manufacturing the Same / Spiral Tube Connections to Corrugated Spiral Tubes with Joints

摘要

The present invention connects a joint for attaching to a corrugated spiral tube, a corrugated spiral tube with a joint attached to the joint, a method of manufacturing the same, and a corrugated spiral tube without a joint attached to the corrugated spiral tube with the joint connected thereto. In order to make it possible to reliably obtain a method of manufacturing and connecting easily and with good watertight performance, the joint (1) for connecting the spiral pipe (A), the annular projection (11) is formed in the middle portion of the axial direction, On one side 1B of this projection, a spiral tube 13 and a spiral projection 13 engaged with each other, and a ring-shaped sealing member 15, 16 capable of compressively deforming to the inner peripheral surfaces of both sides thereof are adhesively formed, The corrugated spiral pipe joint, through which the hardening liquid injection inlet 17 is formed in a portion between the sieves 15 and 16, and the joint is fitted into the tube end a of the spiral tube, and the positive ring sealing The space part 5 between the sieves 15 and 16 By using the inlet port 17 and the corrugated spiral tube with a joint, which is filled with the cured product C of the curing liquid, and the fitting port 1 is connected to the pipe end a of the line tube A in a watertight manner. Inject the curing solution, and fill the space portion 5 with the hardened material (C) to connect the joint (a) of the joint (1) and the tube end (a) of the spiral tube (A) in a watertight manner. In the method of manufacturing the pipe and in connection of the other corrugated spiral (A ') to the corrugated spiral tube (A) with one joint in this manner, the bone portion (d) of the tube end (b) of the other spiral tube (A'). The endless projection 1A of the joint body 1 after inserting the fibrous index member 5 into the groove and inserting the elastic seal ring 6 having a plurality of annular irregularities 6a .... It is a method of connecting the other spiral pipe A 'to the corrugated spiral pipe A with a joint which press-fits and connects inside.
