Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a novel piping structure such as a water supply pipe or a hot water supply pipe for construction piping on a building wall, floor, or the like.

(Prior Art) Conventionally, as shown in FIGS. 8 and 9, in the case of a hard pipe such as a metal or a hard plastic, a straight pipe is cut into necessary dimensions, and a soft pipe is cut. Using a tool such as a bender to produce a curved part, using screws, welding, adhesives, pipe connection parts such as flanges and joints, straight parts,
Manufacture a piping system consisting of a curved part, a branch part, a pipe diameter changing part, etc. Also, as shown in JP-A-59-98937, a double pipe method in which a flexible pipe without a branch portion and a joint is inserted into a protective tube having a high rigidity, and as shown in JP-A-59-199931. As described above, there are a type in which a flexible tube is inserted into a similarly flexible sleeve tube and buried in the floor, and a type in which only a vertical tube is a hard tube and only a horizontal tube is a flexible tube.

(Problems to be solved by the present invention) As shown in the previous section, the method using hard pipes has low work efficiency and the joints may come off due to the shaking of the building due to an earthquake or the like. However, there are problems such as water leakage due to electrolytic corrosion and deterioration of the water flow function due to the attachment of scales, and replacement of pipes also involves sizing and repair of the frame, which imposes a large cost, time, and burden on residents.

Also, as described in JP-A-59-98937 and JP-A-59-199931, a construction method based on pipe replacement is also used, but in the present invention, workability on site and parts cost are reduced. The aim is to improve the reliability of parts, the level of understanding and proficiency on the site side, the reliability of the building against shaking and vibration, and various points of water leakage countermeasures without using special parts, tools, knowledge, skills, etc. is there.

(Means for Solving the Problems) In order to achieve the above object, the building piping structure of the present invention has a double pipe structure having a flexible tube inside a flexible sheath tube, and a supply-side end sheath tube is provided. It is connected to a water separator housing that houses the water separator and has a watertight structure and has a drainage hole that communicates with the rainwater pipe, and the inner pipe has a sufficient draw-out sill in the housing and a margin enough to absorb thermal expansion. While connected to the water separator, the sheath tube on the faucet side (discharge side) of the double flexible tube is fixed to the perforated portion of the wall or floor, and the inner tube is connected to the faucet via the faucet fixing bracket. Hold and fix the faucet fixture to the perforated portion of the wall or floor.

The piping system is constructed independently for each faucet device, and is provided with a large radius of curvature without branching, different diameter portions, valves and the like in the middle.

(Operation) Due to the above-mentioned piping structure, the number of joints is very small, so that the construction can be performed very easily and in a short time, and the flexible pipe absorbs the shaking and vibration of the building. The replacement of the inner pipe is extremely easy due to the simple connection method of the radius, the water separator and the faucet, as will be described later in the embodiment, and even if a water leak accident occurs due to deterioration of the inner pipe or other causes, Leakage is discharged through the drainage pipe of the casing tube and the water separator housing and does not affect the building. In addition, as shown in the construction example below, all parts, tools, knowledge can be constructed,
It is extremely easy to understand and learn on the site side when introducing technology.

Example Next, an example will be described with reference to the drawings (FIGS. 1 to 7).

10 is a flexible sheath tube which is individually piped from the supply side such as a water supply / hot water supply source to the use side such as a faucet in an immovable portion such as the underfloor F and the wall W of the building, The flexible sheath tube 10 employs a flexible hose which is particularly flexible and hard to be crushed. Specifically, for example, the flexible sheath tube 10 is extremely flexible, lightweight, rich in negative pressure resistance, weather resistant, and water-impermeable. Uses polyethylene CD tubes for power cable burial.

In particular, it is desirable that the durability of the pipe itself is equivalent to the life of the building structure (about 50 to 60 years), but as described later, the replacement work when replacing the pipe is extremely simple, so even if it is not a custom pipe, The good thing is, of course.

As shown in FIG. 1, the flexible sheath tube 10 having flexibility is piped without any joint member such as an elbow on the way from under the floor F to the wall W. Base end 10A
As shown in FIG. 3, a hose band 14A is connected to one of the openings (13A, 13B,...) Of a housing 13 in which a header 12 as a water separator is housed in a watertight manner. The drainage hole 15 is connected to a drainage pipe 16 communicating with the rainwater pipe side. Further, an elbow 17 of a vinyl tube forming the end of the flexible sheath tube 10 is fixed to a wall W (or a floor F), and a straight tube 18 of the vinyl tube is flexible by a CD tube heterogeneous joint 14B. The other end 10A of the piping system is connected to one end 10B of the sheath tube 10.
In, the flexible sheath tube 10 accommodates the header 12 and the drain hole 15
Are connected to a watertight housing 13 having openings 13A, 13B,..., And one end of a water-supply polyethylene pipe 24 as a flexible inner pipe is connected to a water supply port of the header 12 by a polypipe joint 23B. . The drain hole 15 of the header 12 communicates with the outside of the building by a drain pipe 16, and the header 12 is connected to a water meter (not shown).

Fig. 3 shows the structure of the piping system. 19A and 19B have one or more faucet mounting holes (20,20,20 ...
A faucet fixing bracket and a fixing plug for hot and cold water mixing faucet, wherein the thread 21A of the faucet 21 is first inserted into the faucet mounting hole 20 from the front side, and the faucet elbow 22 (or elbow) is inserted from the back side. One end of the faucet elbow 22 is connected to the other end of the faucet elbow 22 via a polypipe joint 23A.

FIG. 1 shows the entirety of the water supply and hot water supply piping inside the apartment, in which the piping structure according to the present invention is adopted only in the water supply system.

That is, the flexible sheath tube 10 having the water supply polyethylene tube 24 therein connects the water taps 21 and the header 12 individually under the floor of the room without branching or changing the pipe diameter. The tube 10 is a lightweight, highly negative pressure-resistant, water-impermeable polyethylene CD tube for burying power cables.

When the faucet 21 is a standing faucet, an angle valve 28 may be used instead of the faucet 21 and connected to the standing faucet 26 by a metal flexible tube 27 as shown in FIG. When the water faucet cannot be used, the faucet fixing bracket 19A is fixed using the floor surface as shown in FIG. 7 (a), and a metal straight pipe 29, a ball valve 30, and a flexible pipe 27 are used in place of the faucet 21. Faucet 26 can be connected via this. Then, for the water supply or hot water supply pipe, remove the polypipe joint 23B on the header side, then remove the fixing bolt 25 of the faucet fixing bracket on the faucet side, and attach the faucet elbow 22 to the faucet 21 and faucet fixing bracket 19A. At the same time, pull out from the elbow 17, remove the faucet elbow side joint 23A, connect the new flexible sheath tube 10 using the poly tube joint to the old flexible sheath tube 10, and then header If the old pipe is pulled out from the side, the pipe can be replaced promptly.

As described above, the piping structure according to the present invention is inexpensive and quick to construct without using any new parts, technologies and tools.
The possibility of a water leak accident is small and the tube can be easily replaced.
