DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe joint used for attaching water supply equipment to a wall plate or a floor plate of a bathroom, a sink, a sink or the like in a house.

[0002]

2. Description of the Related Art Generally, in apartment houses and detached houses,
When performing water supply and hot water supply piping to bathrooms, washstands, sinks, etc., use a bellows-shaped sheath pipe under the floor or behind a wall between each header of water and hot water and the faucet fittings when building the frame of the building. A sheath pipe method is provided in which a water supply pipe for supplying water and hot water is inserted into the sheath pipe at an appropriate time later. This example is shown in FIG.
Briefly described, a bellows-shaped sheath tube 32 is provided in advance from a header 31 for supplying water and hot water under the floor,
A water pipe 3 made of a synthetic resin such as a polyethylene pipe later
3 is inserted into the sheath tube 32 and connected to the header 31, and the pipe joint 3 fixed to the wall hole 35 of the wall plate 34 raised from the floor.
6 connects a water pipe 33 raised from the floor along a wall plate 34 with a cap nut 37, and a faucet fitting 3 on an exposed side opening.
8 can be attached.

FIGS. 9A and 9B show a pipe joint 36.
a and 36b are used as floorboards for cabinets such as washstands, sinks, etc.
4a. The pipe joints 36a and 36b are fixed to floor holes 35a formed in the floor plate 34a of the cabinet, and on the floor, water supply devices such as water supply pipes and water stopcocks communicating with a water faucet (not shown) installed on the top plate. 38 (a), the water pipe 33 piped along the floor plate 34a is connected by a cap nut 37 in (a), and the floor plate 34 is connected in (b).
The water pipe 33 laid along the line a is connected directly to the pipe joint 36b.

[0004] In this sheath pipe method, it is possible to easily renew the water pipe when the water pipe deteriorates due to aging, but in this case, at the time of equipment work performed after the skeleton work, a normal partition wall is provided behind the wall plate. It is not easy to work in the narrow space between the wall plate and the partition wall, so remove the faucet fitting and the pipe joint fixed to the wall plate on the front side of the wall plate, and insert it into the sheath tube. After pulling out the old water pipe, inserting a new water pipe and fixing it to the pipe joint, insert the pipe joint into the wall hole again and fix the faucet fitting to the wall plate. Due to the curved shape, it was not able to pass through the small-diameter wall hole well and collided with the wall plate, resulting in poor workability. In addition, when the sheath pipe is passed through the wall hole, the water pipe needs to be largely bent to conform to the wall plate, and if the water pipe is forcibly bent, the water pipe is deformed, which may cause water leakage. Furthermore, even when the pipe joint is mounted on the floor plate, the work of mounting and removing the water pipe must be performed in a narrow space below the floor, as in the case where the pipe joint is mounted on the wall plate, and the workability is poor. .
