Furthermore, in this case, the wall hole 61 can be made smaller than when fixing with the screw 90 from the wall material 60, and there is no need to change the size of the screw 90 depending on the thickness of the wall material 60, and the fixation can be fixed. can do.

In addition, in the case of piping of the fluid pipe 30 that passes hot water or water, water may leak from the connection between the fluid pipe 30 and the joint 50. In such a case, as shown in FIG. 12, there is a peripheral wall that is fitted tightly into the fluid pipe 30 and surrounds the connection point between the fluid pipe 30 and the joint 50, and is a guide for guiding water leakage to the cover member 80. Mizuguchi 1
It is preferable that a packing 110 having a diameter of 11 is attached to the fluid pipe 30, and a drain port 81 is provided at the bottom of the cover member 80 so that leakage water can be drained from the drain port 81.

Further, the fluid pipe connecting joint according to the present invention can have a structure in which it is integrally formed with a gas valve, as shown in FIG. 13. This is because the joint 50 is attached from the wall surface after the wall material 60 is erected.

(Effects of the Invention) As explained above, the fluid pipe piping method according to the present invention includes a method of fixing a joint having a right-angled contact portion that contacts an exposed portion of a crosspiece or a column and its orthogonal surface;
In other words, since it is a method of fixing the joint to the object to be fixed on two sides, there is no possibility of return due to curling of the fluid pipe.
In addition, even when the fluid pipe returns to bending due to its stiffness, the joint does not bow or turn upward, and the joint can be securely and firmly fixed.

Furthermore, in the piping method, at least one side of the crosspiece or pillar installed at the back of the wall is exposed so as to face into the wall hole, so the joint can be fixed from the front side of the wall.

Further, since the fluid pipe connecting joint according to the present invention is provided with the right-angled contact portion, the force caused by the return due to the curl of the fluid pipe or the return due to bending due to the stiffness of the fluid pipe is reduced. For example, even if it is added to one surface of the right-angled abutment part, it acts to restrict by another surface perpendicular to this, and can be used directly in the piping method described above. Moreover, it acts to reinforce the load of a water faucet, gas faucet, etc. connected to the joint, so that the faucet or gas faucet can be securely fixed.

By making the right-angled contact part flush with the water faucet or gas faucet connection port, most of the joint can be accommodated within the wall hole, and there is no protrusion on the wall surface, making it ideal for indoor use. It does not spoil the beauty of the product.
