STRUCTURE OF ELBOW FOR WATER SUPPLY PIPE AND WATER PRESSURE/FIXING PLUG AND FAUCET CONSTRUCTING METHOD THEREBY

摘要

A structure of an elbow for a water supply pipe and a water pressure/fixing plug and a faucet installation method using the same are provided to fix location easily by fixing an elbow for a water supply pipe to a form at the construction of a concrete retaining wall and to cut off water pressure and to prevent the inflow of impurities to an elbow before a faucet is installed after the retaining wall construction. An elbow(10) a water supply pipe comprises an elbow main body(11) composed of a flexible pipe socket(111) coupled with a flexible pipe and a head(112) provided with a faucet fastening hole(112a) coupled with a faucet and a socket screw hole(112b), a case(12) provided with a primary opening(121) to insert the elbow main body to be fixed to a case screw hole(121a) by fixtures(14) and a secondary opening(122) coupled with a CD pipe socket, a stopper(13) provided with a third opening(131) formed to make the head of the elbow main body exposed, a ring-shaped primary projection(132) projected forward along the edge of the third opening, a ring-shaped secondary projection(133) inserted closely to the inside of the primary opening and a ring-shaped third projection(134) adhered closely to the outer circumference of the head, and a pipe protection pipe(16) coupled closely to the outer circumference of the primary projection of the stopper of the elbow and formed to be projected higher than a waterproof coating and a tile layer. A water pressure/fixing plug comprises a water pressure/fixing plug main body(21) provided with a flange(211) and a primary screw groove(212) coupled to the socket screw hole of the head, and a fixture(22) coupled to the water pressure/fixing plug main body and provided with a hexagonal part(221) for connection with a wrench and a handle(222) to rotate with hands.
