Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elbow for a wall-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elbow for a wall surface piping and a method of constructing the same. More particularly, the present invention relates to an elbow for connection with a faucet, And an elbow for a wall surface piping and a method of constructing the same so that the connection with the faucet can be easily performed.

Generally, a water supply valve (also referred to as a faucet) is a valve that mixes or selects only hot / cold water supplied through a cold / hot water supply pipe, (Including hot water through a boiler) supplied from a user, while controlling the water temperature by selecting cold / hot water or mixing them to provide the user with the water temperature.

The faucet may be installed on the wall above the sink of the kitchen, or on the wall surface of the bathroom (including the bathroom) so that the user can operate the lever when necessary to use the water at the proper or desired temperature and flow rate.

Such a faucet 1 is provided with a valve cartridge 3 inside a water valve housing 2 and includes an adjustment knob 4 exposed to the outside of the water valve housing 2, Thereby opening and closing the valve cartridge 3 and discharging the water to the discharge port 5.

The two ends of the water valve housing 2 are connected to each other through an "S" -shaped connection arm 6 having a male and female threads (a nut coupled to one end and a screw tab on the outer peripheral surface on the other end) Hot water supply piping (C, H) which is embedded in the concrete layer of the wall and supplies cold / hot water.

At this time, the connection arm 6 is connected to an elbow (E) connected to the tip of each of the cold / hot water supply pipes (C, H) through a nipple (7).

As shown in FIG. 2, the method for constructing the faucet and the hot / cold water supply piping C and H for the conventional wall-mounted hot water supply pipe An elbow-open end tape sealing step (Sa) for sealing the other open end of the elbow (E) with a chelate tape to prevent inflow of concrete to be laid; A fixed position display step (Sb) of displaying the fixing position of the end of the elbow (E) sealed with the cheek tape against the die; A securing step (Sc) for securing the elbow (E) to the nail by means of a nail; A concrete pouring step (Sd) for supplying and curing concrete; After the concrete is cured, a mold removal step (Se) is carried out to remove the mold; An elbow open end opening step (Sf) for releasing a cheek tape sealing the other open end of the elbow (E); An elbow open end plug sealing step (Sg) for sealing the open end of the elbow (E) with a plug for hydraulic check; A water check step (Sh) for supplying water to the cold / hot water supply pipes (C, H) to check the water pressure; A wall finishing step (Si) applying a mortar to the concrete surface and applying a tile; A plug removing step (Sj) for pulling out a plug from the elbow (E); A nipple connection step (Sk) for fixing the nipple (7) to the elbow (E) for connection with the faucet (1); Lt; / RTI >

However, in the conventional art as described above, it is very cumbersome to seal and remove the open end of the elbow (E) with a cheek tape to prevent the concrete from being infiltrated when the concrete is poured. To check the water pressure, There is a problem in that it is necessary to prevent the water from flowing out by inserting it into the open end of the pipe E and to remove it again after checking the water pressure.

In addition, when the elbow E is nailed and fastened to a mold, the elbow E is shaken and it is difficult to fix the elbow E in an accurate position. In general, since the mold is repetitively nailed to a mold used repeatedly, A number of nail holes are formed at a portion where the elbow (E) of the form is fixed, so that the fixing force is lowered or the fixing itself becomes impossible.

In addition, since the connecting arm 6 of the faucet 1 is fixed in a state in which the nipple 7 is coupled to the elbow E, the configuration and structure are complicated, .
