Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a new piping method for water supply and hot water supply pipes in buildings.

Various types of piping for housing units in buildings such as apartment complexes, such as water supply piping, can be installed directly in the slab on the side of the building, considering the difference in service life between the building frame and the piping, aging of the water supply pipe, and replacement due to water leakage. Since it is not possible to bury the piping in the building, a piping space such as a double floor is usually formed on the building frame, and the piping is rolled inside the piping space, and the piping is installed inside the double partition wall. However, even with this, it is still necessary to demolish the finishing materials on the indoor side in order to replace the water pipes, and the replacement work is the grand prize, which takes a lot of time and effort, and costs a lot. It's a huge amount. In particular, water leakage from piping is caused by the rigid structure of the piping, and water supply pipes made of materials such as hard vinyl chloride pipes are complicatedly bent using joints such as elbow cheese. Therefore, water leakage is inevitably promoted from these joints, and this tendency is further aggravated by shock waves in the pipe such as water hammer.

Therefore, since water leaks always occur in conventional piping structures, and they occur frequently, it is at least economically viable for residents to carry out the above-mentioned grand replacement work each time they occur.
The mental burden is too great. In addition, joining the joints requires gluing and screwing, which is time-consuming, and also requires dimension matching (measuring), so skilled workers are essential, and in addition, it is necessary to perform seal inspections, etc. However, there was a drawback that it required a lot of effort.

The present invention was devised in order to eliminate the above-mentioned practical difficulties at once.The present invention has been devised to eliminate the above-mentioned practical difficulties at once. The main idea is to use a double pipe construction method that uses combustible pipes that do not require joints.

That is, the present invention allows a relatively rigid protection pipe to be piped through a required piping route between the supply side of water supply/hot water sources, etc. and the use side of faucets/hot water faucets, etc. when constructing a building. During the piping, a flammable pipe without a joint or branch part in the middle is inserted into the protection pipe in advance, or after piping, both ends of the flammable pipe are connected to the supply side and the use side. It is characterized by being connected.

Hereinafter, the details of the present invention will be explained by taking the water supply piping shown on the front side as an example. A branch pipe 3 is branched from an appropriate position of the main v2, and a water meter 4 is installed on this branch pipe 3.On the downstream side of the water meter 4, a water heater is installed. , a kitchen, a toilet, a bathroom, a washroom, etc., or a number of water supply ports 1)a, 6be6C, .

8 indicates the double floor, 9 indicates the double floor space directly below it,
10 is a partition wall on the use side, 11 is a space within the partition wall, and a water faucet 12.15 is attached to the partition wall 10.

In a structure having such a structure, the protection pipe 14 extending between the water distribution basin 15 side and each faucet 12, 15 is installed prior to pouring the floor concrete of the frame 1, or after the floor concrete has hardened and prior to interior finishing. .15 is plumbed.

These protective tubes 14.15 are made of relatively rigid materials such as metal tubes or synthetic resin tubes, and independent protective tubes 14.15 are used for each user-side faucet 12.15.
Therefore, the protective tubes 14 and 15 have a structure in which there is no branch part in the middle of the piping. Furthermore, the first
In No. 8, the protective tubes 14 and 15 are passed through the partition wall space 11, but this is because the water faucet 12 and 15 is attached to the partition wall no. Of course, it changes depending on the position. After this piping,
At an appropriate time, for example, after the interior construction is completed or #1 is completed, a long piece of real flexible pipe (e.g. rubber pipe, corrugated synthetic resin pipe) 16 with no joints or branch parts in the middle is used. .17
are inserted into the protection tubes 14.15, and their distal ends are communicatively connected to the water faucets 12.15, respectively, and their proximal ends are either water inlets 6a of the water distribution header 5.

6b, 6C, and so on. In addition, protection tube 14.
When installing the pipes 15, it is also possible to enter the flexible pipes 16 and 17 in advance.

If such a construction method is used, the water supplied from the main water supply pipe 2 is passed through the water faucet 12.1 through mv1b and 1y, respectively.
Furthermore, when the combustible tubes 16 and 17 leak or deteriorate, they can be extracted from the protective tubes 14 and 15 and replaced with new ones.

On the other hand, it goes without saying that method 1 can also be applied to hot water supply piping and other applications.

Note that 18 in FIG. 11 indicates a piping take-out box.

As mentioned earlier, the present invention uses a protective tube and a flexible tube passed through it to supply water and hot water, and the water and hot water are supplied through the visible tube, which is the inner tube. In the event of water leakage or deterioration, only the combustible pipe needs to be replaced, and it will be destroyed again, so replacement work is easy and does not involve destroying the finishing materials of the frame as in the past. .

Therefore, it has the advantage of significantly reducing replacement costs and reducing the mental and economic burden on residents.

Since the protection tube bears the external pressure used for the combustible tube and does not need to be replaced, it can be buried directly within the building frame, and in this way, it can have a piping space such as a double floor. Since there is no need for finishing, the structure and construction cost of the building can be reduced.

By using visible pipes, it is possible to eliminate the need for a sticky structure even if the piping path is bent, which improves workability and reduces costs.It also saves labor in processing and measuring fittings on site. Moreover, it can be easily operated even by unskilled people. This means that the locations for water leakage prevention can be limited to the connection points between the water diversion header and the faucet.

In addition, the flexibility and elasticity of visible pipes allows them to absorb internal shock waves caused by water hammer, etc., so no abnormal force is applied to the water supply/hot water supply equipment, allowing them to have a long service life. Combined with the fact that there is less water leakage, water leakage accidents can be further prevented.
