Title:
ONE-TOUCH THREE-STAGE JOINING APPARATUS FOR FITTINGS FOR CONNECTING PRESSURE PIPES, AND METHOD FOR CONSTRUCTING PRESSURE PIPES USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/030829
Kind Code:
A1
Abstract:
The present invention relates to a one-touch three-stage joining apparatus for fittings for connecting pressure pipes, and to a method for constructing pressure pipes using same. More particularly, an organic joining structure comprising a fixing structure formed in a pressure pipe insertion/tight-contact portion (A) and a bushing insertion/tight-contact portion (D), a double frictional resistant structure formed by a joining element (20), and a watertight structure formed by watertight rubber packing is arranged in the fitting for connecting pressure pipes, thus achieving a one-touch joining structure in which the joining/fixing of the pressure pipes can be achieved simply by the single operation of pushing the pressure pipes into the fitting for connecting the pressure pipes. As the apparatus and method of the present invention adopt a one-touch system, easy joining/connection and efficient connecting work can be achieved, and a construction period can be shortened. Further, the apparatus of the present invention adopts a one-touch joining/fixing structure using pressure pipe insertion equipment, thus eliminating the necessity of direct joining work by a worker to thus eliminate the necessity of a separate space for excavation work, thereby enabling an excavation to be performed in an efficient and economically advantageous manner.
