Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is a piping method for fluid pipes for passing hot water, water, and gas, and is a method for piping fluid pipes to a composite stopper that requires a plurality of fluid pipes. This article relates to a piping method and a piping box, which is a piping tool used for this method.

(Prior art) Recently, in residential buildings, for example, compound taps (commonly known as mixer taps) that supply hot water and cold water at the same time are being used.
is often used.

Conventionally, for piping of such a composite faucet, a method has been adopted in which a fluid pipe through which hot water passes and a fluid pipe through which water passes are arranged separately and independently behind the wall.

(Problem to be solved by the invention) However, such conventional piping methods,
Among the fluid pipes through which hot water or water passes, first install one fluid pipe behind the wall, connect a joint to its end and fix the joint, then connect the other fluid pipe behind the wall,
You have to go through the steps of connecting the joint to the end and fixing the joint, which requires you to do the piping work twice behind the wall, which is very time-consuming. The heights and directions of the connection ports of the respective joints to be connected tend to be uneven. For this reason, the connection ports of each joint may be distorted and appear on the wall surface, spoiling the aesthetic appearance of the wall surface, and due to misalignment of the connection ports of such joints, the connection of the composite stopper may not be successful. Ta.
In particular, when piping is installed in a concrete wall, the fluid pipes and joints are buried in concrete, and repair work requires tearing through the concrete wall to repair the piping after installation, making the repair work difficult.

The present invention has been made in view of the above circumstances, and provides a piping system that enables quick piping work of fluid pipes, allows the connection port of a joint to be reliably installed in a predetermined position, and does not cause any trouble in connecting a composite stopper. It is an object of the present invention to provide a piping method that allows subsequent repair work to be easily performed, and to provide piping equipment suitable for the piping method.

(Means for Solving the Problems) In order to solve the above problems, the method of piping a fluid pipe to a composite stopper adopted by the present invention is as follows. A piping box equipped with a mounting port and an opening communicating with the piping box is provided behind the wall, and then a wall is provided, and then a plurality of flexible fluid pipes for passing hot water, water, and gas are piped into the piping box to connect the fluid pipes. Pull out the ends of the fluid pipes from the openings of the piping box onto the wall surface, then connect the joints to the ends of each fluid pipe, distribute the fluid pipes to the joint mounting ports of the piping box, and then fix the joints inside the piping box.
The second method is to install a piping box on the back of the wall that houses a plurality of fittings, has a plurality of fitting openings for installing these fittings, and an opening that communicates with the fitting openings, and then Attach protective caps to the joint mounting ports and openings, then set up wall material, provide wall holes in the wall material into which the protective caps fit, then remove the protective caps from the piping box, and then pour hot water into the piping box. Pipe multiple flexible fluid pipes for passing water and gas, pull out the ends of the fluid pipes to the wall surface through the openings of the piping box, then connect joints to the ends of each fluid pipe, and attach the fluid pipes to the joints of the piping box. Distribute them to each port, and then fix the fittings inside the piping box.
The third is a flexible tube into which multiple flexible fluid pipes for passing hot water, water, and gas are inserted, and multiple fittings, and multiple fitting openings for attaching these fittings. A protective piping passage is formed behind the wall using a piping box with an opening that communicates with the piping box, and then a protective cap is attached to the joint installation opening and the opening of the piping box, and then a formwork is erected and concrete is poured. Pour the concrete,
After the concrete has cured, the formwork is removed and the protective cap is removed from the piping box. Next, multiple fluid pipes are piped into the protective piping passage, and the ends of the fluid pipes are pulled out from the opening of the piping box to the wall surface, and then each fluid is Connect the fittings to the ends of the pipes, distribute the fluid pipes to the fitting installation ports of the piping box, and then fix the fittings inside the piping box.
It is something.

Among these methods, the first and second methods are piping methods using wooden partition walls, and the third method is piping methods using concrete walls. All of these methods are aimed at piping a fluid pipe to a composite stopper.

A decorative plate 29 is attached to the joint mounting port 12 and opening 13 of 0.

Thereafter, a connecting pipe of a composite stopper is connected to the connecting port 51 of each joint 50.

In addition, when piping is performed using this wooden partition wall, a piping method without the protective cap 30 can also be adopted. In addition, when the fluid pipe 70 is temporarily fixed directly under the piping box 10 fixed to the back of the wall or temporarily fixed to the piping box, the fluid pipe 70 is pulled up and pulled out to the surface of the wall after the wall material is erected. In this case, a piping method without the flexible tube 30 can be adopted.

Next, the case of piping in a concrete wall with a finishing wall will be explained.

For piping in concrete walls with finishing walls,
First, the piping box 10 is connected to the end of the flexible pipe 60, and the piping box 10 is fixed to a bar material installed on the support beam to form a protective piping passage.

Next, protective caps 30 are attached to the joint mounting ports 12 and openings 13 of the piping box 10, a formwork is erected, and concrete is poured.

After the concrete has cured, the formwork is removed as shown in Figure 15. Next, as shown in FIG. 16, a coating allowance cap 40 of the same shape is attached to the protective cap 30, and then, as shown in FIG. 17, the surface wall 110 is finished with mortar or the like.

Next, as shown in FIG.
0 and the protective cap 30 are removed from the piping box 10, and a plurality of fluid pipes 70 are piped into the protective piping passage, as shown in FIG.
The end of the pipe is pulled out from the opening 13 of the piping box 10 to the wall surface.

A joint 50 is connected to the end of each fluid pipe 70 that has been pulled out, as shown in FIG. Sort it out.

Next, as shown in FIG. 21, the joint 50 is placed in the piping box 10 so that the connection port 51 of the joint 50 faces the outside, and fixed with the fixing ring 21.

After the joint 50 is fixed in the piping box 10 in this way, the piping box 1 is fixed as shown in FIG.
A decorative plate 29 is attached to the joint mounting port 12 and opening 13 of 0.

Thereafter, a connecting pipe of a composite stopper is connected to the connecting port 51 of each joint 50.

In addition, for piping in a concrete wall without a finishing wall, after curing the poured concrete, remove the formwork and remove the protective cap 30 from the piping box 10, as shown in Figs. 19 to 22. Alternatively, a method may be adopted in which a plurality of fluid pipes 70 are arranged in the protection pipe passage.

(Effects of the Invention) As explained above, in the method for piping fluid pipes to a composite stopper according to the present invention, the opening of the piping box from which a plurality of fluid pipes are drawn out communicates with the joint mounting port for mounting the joints. Therefore, multiple fluid pipes that have been piped together can be distributed later.

Furthermore, in the piping method, the joints connected to the ends of each fluid pipe are fixed in the piping box, thereby making it possible to fix the joints in predetermined positions.

Therefore, the piping work of the fluid pipe can be performed quickly, and the connection port of the joint can be reliably installed at a predetermined position without causing any trouble in connecting the composite stopper.

In addition, the fluid pipes and joints can be installed after constructing the wall material or concrete wall, and repair work after piping can be easily performed.

Furthermore, since the piping box used in the above piping method is equipped with a plurality of fitting mounting ports and an opening that communicates with these, multiple fluid pipes behind the wall can be pulled out from the opening at once, and Fluid pipes can be distributed to the joint mounting ports communicating with this.

In addition, by using piping boxes and protective caps, it is suitable for various types of piping, such as piping through wooden partition walls, concrete walls, or concrete walls with finishing walls. Can perform piping work for fluid pipes.
