DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping system for water supply and hot water supply in an apartment house and the like, and to a water supply standpipe used for this apparatus.

[0002]

2. Description of the Related Art In a water supply device for a condominium or other condominium, various piping systems as described below have been proposed, but each has its own problems.

(1) Conventional piping system I As shown in FIG. 9, water is pressure-fed from a water receiving tank 50 to a water supply vertical pipe 52 by a pressurizing pump 51, and this water supply vertical pipe 5
2 is a system in which a water supply pipe 53 is branched to each floor 1F to 4F of a building, a plurality of water supply branch pipes 54 are branched from the water supply pipe 53, and water is supplied to a terminal plug 55 at each water supply point on each floor.

However, in such a piping system, the pipe is branched from the upstream side with a thickness corresponding to the required water supply amount of each floor, and the required water supply amount decreases further downstream, so that the pipe diameter is gradually reduced. It is necessary to cut a large number of pipes to a predetermined size, cut the ends of the pipes, and screw up the joints.

[0005] Further, since these pipes use galvanized steel pipes, there is a problem that so-called red water is generated due to corrosion in the pipes. In order to prevent this, steel pipes with vinyl lining on the inner surface are sometimes used, but in this case, not only is it difficult to line the joints, but also the lined vinyl peels off and the pipes There is a problem of blocking.

(2) Conventional Piping System II As shown in FIG. 10, a main water supply pipe 61 connected to an elevated water tank 60 is horizontally extended on the top floor of a building.
A water supply header 62 common to the same section of each floor is attached to a predetermined location of the water supply main pipe 61, and the water supply header 62
And each water distribution header 63 provided on each floor in the same section are connected by independent water supply pipes 64 respectively. Water distribution header 63 and terminal plug 66 at each water supply point in each house
And are connected by a branch pipe 65.

[0007] Both the water supply pipe 64 and the branch pipe 65 are made of a soft copper pipe, and can be piped without using an intermediate joint by appropriately bending, so that the problem of the prior art I can be solved. Because it is a copper tube, patina is generated by oxidation and causes so-called blue water.

In addition, since the water supply pipe 64 from the water supply header 62 on the top floor to the water distribution header 63 on each floor is an independent pipe, the total pipe length becomes excessively large and a large amount of copper pipe is required. is there.

(3) In order to prevent the above-mentioned blue water, synthetic resin tubes may be used. However, these tubes are fragile, have low heat resistance, and have the problem of increasing brittleness over time. .

As a method for solving this problem, Japanese Patent Laid-Open Publication No.
86681 and JP-A-59-98937. This is because a protective tube is buried in the installation place such as a pipe to each water supply point, and an inner tube made of a flexible material such as polybutene, polyester, or soft polyethylene is inserted through the inside of this protective tube. In addition to preventing damage to the inner pipe after installation and construction, the inner pipe can be replaced as a measure against weakening over time.

However, in such a piping structure,
Since the pipes are doubled, it is necessary to perform the pipes twice in the same path, so that there is a problem that the labor and the pipe material are doubled.

[0012]

As a solution to the above problems of the prior art at once, the following water supply device has been proposed. In this water supply apparatus, as shown in FIG. 11, a stainless steel water supply header 70 (primary header) is disposed on each floor of the building, and water is supplied to the water supply header 70 by a stainless steel water supply standing pipe 71. The water supply header 70 and the terminal plug 76 of each house are connected by a water pipe 72 made of soft stainless steel.

In addition, each home has a water distribution header 73
Hot water supply distribution header 75 for water heater 74 (secondary header)
And a water supply branch pipe 77 connecting the water supply distribution header 73 to the water heater 74 and the terminal plug 76 at the water supply point, and a hot water branch pipe 7 connecting the hot water distribution header 75 and the terminal plug 76.
8 is made of soft stainless steel.

In such a water supply device, since the header and the pipe are made of stainless steel which is hardly oxidized, generation of red water and blue water can be prevented, and the pipe between the header and the terminal plug is made of soft stainless steel. Since a steel pipe is used, there is no need to use a joint in the middle, and since the pipe can be bent and piped, there is an advantage that there is no risk of water leakage and the pipe construction is easy.

However, since the water supply pipe 72, the water supply branch pipe 77 and the hot water supply branch pipe 78 are so-called rolled floors, which are disposed in the gap between the floor surface and the floor finishing material, the floor height of a recent apartment house is low. In order to compensate for this, when a straight floor type is adopted, a space for piping cannot be taken, and piping is difficult in the above-described floor rolling method.

Further, a water supply header is required separately from the water supply distribution header and the hot water distribution header, and the piping from the water supply header to each house becomes longer, and the number of members increases.
In addition, the mounting work and the piping work become troublesome.

Further, in a conventional general stainless steel water supply standpipe, one or two T joints are provided on each floor,
In this case, a T-joint is welded to the center of the standing pipe member, these standing pipe members are carried to the site, and the standing pipe members on each floor are connected by a socket. I was For this reason, an extra socket is required for each floor, the cost of joint materials and the cost of connection work are increased, and the advantage of factory processing by a prefab is halved.

Further, in the production, the standing pipe and all the joints are once transported to a processing plant, and a T-joint is attached to the standing pipe member by welding or the like. Was transported to the site in small lots,
There was a problem that transportation cost and distribution cost were required.

The present invention has been made in view of the above-mentioned circumstances, and has an object to be applicable to a straight floor type or the like in which piping cannot be performed under the floor, and to perform piping construction easily and quickly. An object of the present invention is to provide a hot water supply / hot water supply pipe system device which can have a simple and compact piping configuration and can have a simple and inexpensive water supply hot water supply pipe, and its water supply vertical pipe.

[0020]

According to the present invention, there is provided a water supply piping system for supplying water to various parts of a building from an elevated water tank or a lower pressurized water supply device, wherein water supplied from the elevated water tank or the lower pressurized water supply device is supplied to each floor. And a stainless steel water supply pipe to be supplied to one or more dwellings, and the pipe is branched from this water supply drip and rises to the bottom of one dwelling, and is piped along the ceiling surface (the lower surface of the upper floor slab). , A stainless steel water supply pipe integrally formed by bending from the branch part to the tip part without using intermediate joints, and the tip of this water supply pipe is connected, and the lower part of the nearest ceiling surface that needs water supply A plurality of water supply branch pipes made of soft stainless steel, which are connected to the water supply distribution header provided in the water supply terminal and the water supply distribution header and the terminal plug at each water supply point, and are integrally piped without using intermediate joints. It consists of.

In the case where the water heater is a centralized water heater common to each dwelling, the hot water supply pipe from the centralized water heater may have the same piping configuration as the above-described water supply piping configuration.

When the water heater is individually arranged in each house, a water supply stand made of stainless steel for supplying water from an elevated water tank or a lower pressurized water supply device to one or more houses on each floor. A pipe, a stainless steel water supply pipe that branches from the water supply riser, rises below the ceiling of one dwelling, is piped along the ceiling surface, and is integrally formed by bending from the branch portion to the tip end; and the water heater From the top of one dwelling to the lower part of the dwelling, the stainless steel hot water pipe that is piped along the ceiling surface and integrally bent from the hot water heater connection part to the tip is connected to the hot water pipe and the hot water pipe tip And the hot water distribution header and hot water distribution header installed on the nearest ceiling surface that requires hot water and hot water supply, the hot water distribution header and hot water distribution header, and the terminal plugs at each water supply point. Connecting the terminal plugs of the hot water portion respectively, consist of a plurality of the water supply branch pipe and the hot water supply branch pipe made of a soft stainless steel integrally pipe.

The water supply pipe and the hot water supply pipe are set up in parallel with other pipes, and are arranged in parallel along the ceiling surface.

Further, the water supply branch pipe and the hot water supply branch pipe may be piped along the ceiling surface and fall at each terminal plug position,
It may be lowered at the installation location of the distribution header, and a so-called floor-rolling pipe may be provided to each terminal plug position.

In a stainless steel water supply standpipe for supplying water from an elevated water tank or a lower pressurized water supply device to one or more houses on each floor, an intermediate portion of a joint main body having a socket pipe above and below is provided. A plurality of female screw members are attached at the same position, and a unit standing tube is connected to the socket tube.

[0026]

In the above construction, the water supply pipe is branched into one or two systems at each floor, and the water supply pipe is directly attached to this branch, so that there is no need to install a water supply header (primary header) on each floor. Also, the water supply pipe from the water supply header to each house can be shortened.

Since the water supply pipe or hot water supply pipe is an integral stainless steel pipe rising along the wall and along the ceiling,
By simply inserting the pipe from the outside of the wall, it is extremely easy to connect the pipe to the ceiling surface.

Since a stainless steel pipe integrally formed by bending into a water supply pipe or a hot water supply pipe is used, there is no need to use a joint in the middle, there is no risk of water leakage, and piping work is facilitated.

Since the water supply branch pipe and the hot water supply branch pipe from the distribution header also use an integral soft stainless steel pipe, no joint is required on the way, and the pipe can be easily bent and piped without any risk of water leakage. In addition, piping work is also facilitated.

Since the water supply pipe, the branch pipe from the header, and the like are made of stainless steel which is hardly oxidized, generation of red water and blue water can be prevented. Further, the stainless steel pipe is excellent in hardness and tensile strength, there is no risk of damage during construction, and the friction loss is small and the diameter of the steel pipe can be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention. This is an example of a piping system in which water is supplied to each floor from an elevated water tank installed on the roof of an apartment house such as an apartment, and hot water is supplied to each dwelling unit for each dwelling unit. 1 is a perspective view showing the piping system, FIG. 2 is a modified example thereof, FIG. 3 is a side view of FIG. 1, and FIG. 4 is a sectional view of FIG.

Referring to FIGS. 1 and 3, a piping system according to the present invention mainly comprises a water supply standing pipe 1, a water supply pipe 2,
It comprises a water heater 3, a hot water supply pipe 4, a hot water distribution header 5, a hot water distribution header 6, a hot water branch 7, and a hot water branch 8.

The water supply pipe 1 is a stainless steel pipe that is provided from the top to the bottom through a corridor and the like, and supplies water to each floor from an elevated water tank on the roof. It is arranged.

In this embodiment, the water supply riser 1 is branched into two systems at each floor so that water can be supplied to two dwellings.
Accordingly, two stainless steel branch water supply pipes 11 each having a water supply water meter (water meter) 12 and an opening / closing valve 13 are connected to a lower part of each floor of the water supply riser 1. In addition, although the joint 30 according to the present invention described later is used for branching the water supply riser 1, it is not excluded that two conventional T joints are provided.

The water supply pipe 2 and the water heater 3 are connected to the distal end of the branch water supply pipe 11 via a T-joint 14. Water heater 3
Is installed in the meter box MB, and its water supply port is provided with a stainless steel water heater water supply pipe 1 having an open / close valve 16.
5 is connected to the T joint 14.

As described above, without connecting a water supply header (primary header) to the water supply riser 1, the water supply riser 1 is branched into two piping systems, and the water supply riser 1 is branched to the water supply riser 11.
By directly connecting the water supply pipe 2 and the water heater 3 via the, the members can be simplified and the piping to each house can be shortened.

The water supply pipe 2 and the water supply pipe 4 from the water heater 3 are
It rises along the outer surface of the wall W, penetrates the wall W, passes through the dwelling, and is disposed horizontally along the lower surface of the floor slab on the upper floor, that is, along the corner of the ceiling surface C. To the water supply distribution header 5 and the hot water distribution header 6 respectively.

The water supply pipe 2 and the hot water supply pipe 4 are made of stainless steel pipes, without using any intermediate joints, and formed integrally by cold bending at a factory or a site.

In the case of an integral unit having such a shape, the wall W
It can be easily piped along the ceiling just by inserting it from outside. In addition, since there is no joint, there is no water leakage, and no water leakage test is required, the piping work can be simplified and the construction period can be shortened.

The hot water pipe (or bathtub circulation) 9 of the bathtub from the water heater 3 and the city gas pipe 10 are also made of stainless steel pipe, and as shown in FIGS. Together with the water supply pipe 2 and the hot water supply pipe 4, four pipes are arranged together. That is, the four pipes 2, 4, 9, and 10 are started up in parallel to the side of the water supply standing pipe 1, and the wall 19 is provided with a sleeve 19 at a location near the ceiling where there is no structural problem in the frame, and the four pipes are connected to the sleeve. In the house, it is fixedly suspended and supported by a suspending support member 20 on the ceiling surface C.

The gap between the sleeve 19 and each tube is filled with mortar or the like, and the suspension support member 20 is provided with, for example, a hanging bolt 20a fixed to the ceiling surface C, and a lower end of the hanging bolt. A member including a holding member 20b for holding the tube and a fixing band 20c for fixing each tube is used (see FIG. 4). In this embodiment, an example is shown in which four tubes are vertically arranged in two stages. However, the present invention is not limited to this.
The tubes may be arranged in one stage, that is, horizontally in a horizontal row. These pipes and the like are covered with a partial finishing material or a ceiling finishing material.

Water supply distribution header 5 and hot water distribution header 6
Is fixed to a wall surface below the ceiling surface C by a support hardware 21 at an optimum location such as a bathroom described later (see FIG. 5). As the support metal 21, for example, a U-bolt 21a holding a header and a support member 21b fixed to a wall are used. Note that headers 5, 6
By adopting a hollow rectangular parallelepiped shape, there is an advantage that attachment processing of members such as joints becomes easy, and attachment becomes reliable and easy.

As shown in FIG. 1, the plurality of water supply branch pipes 7 and the base ends of the hot water supply branch pipes 8 are connected to the water supply distribution header 5 and the hot water distribution header 6 through joints 22, 23, respectively. Have been. The tip of the water supply branch 7 is bathroom, kitchen,
It is connected to a terminal plug 24 at a water supply point such as a washroom, a toilet, a washing machine pan unit, and the tip of the hot water supply branch pipe 8 is also connected to a terminal plug 24 that requires hot water. Needless to say, the water supply branch pipes 7 and the hot water supply branch pipes 8 have pipe diameters selected in accordance with the locations where they are used.

The water supply branch pipe 7 and the hot water supply branch pipe 8
As shown in FIG. 1, piping may be performed along the ceiling surface C to each terminal plug 24, and may be lowered at each terminal plug position. Alternatively, as shown in FIG. In a bathroom or the like where the distribution header 6 is installed, all the branch pipes 7 and 8 may be juxtaposed and lowered along the bathroom wall, and the floor may be rolled to the position of each terminal plug 24 to form a pipe.

The water supply branch pipe 7 and the hot water supply branch pipe 8 branching from the header are made of a soft stainless steel pipe, and are piped by hand bending to the terminal plug 24 without using any intermediate joints. Piping along.
For this soft stainless steel tube, for example, SUS304 or SUS316 that has been subjected to a special annealing process or by adjusting the chemical composition thereof can be used whose mechanical properties have improved softness.

The external dimensions of this soft stainless steel pipe are J
IS G3448- (1980) "Stainless steel pipe for general piping" is the same as that specified in general stainless steel pipe. ~ 100m long one
A coiled tube wound into a coil having a diameter of 1.3 m can be brought to a construction site.

When this coiled tube is pushed and rolled on the floor, the tube is extended in a straight line. Therefore, the tube is cut into a predetermined length and bent into a predetermined shape, and then piped to the ceiling or floor. The mechanical properties of the soft stainless steel pipe most suitable for such a piping work are 540 to 640 N / mm ² , and the proof stress 19
5 to 295 N / mm ² .

By using such an integrated soft stainless steel pipe, the pipe can be bent by hand, and since there is no joint, there is no water leakage and no water leakage test is required, the piping work is simplified and the construction period is shortened. be able to.

The cause of the noise generated in the branch pipes 7 and 8 in the metal support for supporting and fixing the soft stainless steel pipe is mainly the rubbing noise generated when the terminal plug is opened. The noise propagates through the branch pipe to the concrete frame and generates noise from an unexpected part of the building.

For this purpose, a support fixture 27 as shown in FIG. 6 is used. This is because a stainless plate having a width of about 15 mm is formed into a substantially U-shape in accordance with the size of each branch pipe.
An anti-vibration material 27c such as anti-vibration rubber is provided between the V-shaped support fitting 27a and the branch pipes 7 and 8. This U-shaped support bracket 2
The branch pipes 7, 8 and the vibration isolating material 27c are held by 7a, and the overlapped flange portion 27b is fixed to the ceiling surface C or the floor surface in the case of a rolled pipe by concrete nails 27d or the like.

The above-mentioned noise can be sufficiently reduced by such a support fixing hardware 27. Also, depending on the flow velocity in the pipe, a water hammer generated when the terminal plug is closed can be reduced by supporting and fixing a required portion such as a bent portion and an intermediate point between the pipe and the like.

The hot water pipe 9 for the bathtub and the city gas pipe 10 are directly piped from the vicinity of the place where the headers 5 and 6 are installed to a necessary place for supporting the ceiling surface.

Water supply distribution header 5 and hot water distribution header 6
Is set at an optimum location in consideration of the pipe length and the pipe direction of the water supply branch pipe 7 and the hot water branch pipe 8 to be distributed. It is preferable from the viewpoint of water leakage and the like.

That is, due to the use of a joint, the joint tightening portion is loosened and leaks due to the input of an external disturbance force (earthquake, etc.) at the branch portion of the water supply distribution header 5 and the hot water distribution header 6 due to the use of a joint. Since it may cause the ceiling and floor finishing materials to be exposed to water leakage, use a ceiling surface where the bus unit is located.

In the case of a bus unit, even if the joint tightening portion is loosened and water leaks, the leaked water flows from the ceiling of the bus unit to the drainage tray set at the lower part of the bus unit. No. Although the ceiling of the unit is exposed to water leakage, if there is a water leak from the drip, it is received at the ceiling of the unit, so that a drip sound is generated and the state of the leakage can be found quickly. Leak repair can be eliminated only by tightening the joints, so it is possible through the inspection opening on the unit ceiling.

The water supply pipe 2, the hot water supply pipe 4, the water supply branch pipe 7,
Use of a stainless steel pipe for the hot water supply branch pipe 8 and the like also has the following advantages.

Since the stainless steel pipe hardly oxidizes, there is no generation of red water and blue water, and extremely sanitary water can be supplied.

Since stainless steel pipes are far superior in hardness and tensile strength to steel pipes and copper pipes, there is no risk of damage during construction, and they are lighter and easier to handle than copper pipes.

Since the friction loss of the water supply pipe 2, the hot water supply pipe 4, the water supply branch pipe 7, and the hot water branch pipe 8 is small, the flow velocity in the pipe is
0.5 m / sec for conventional steel pipes, 0.5 to 1.5 m / sec for copper pipes
With respect to seconds, it can be 0.5 to 3.5 m / sec,
Since cavitation erosion does not occur even if the flow velocity in the pipe is increased, the piping system can be configured with a narrow pipe diameter as a whole.

Here, generally, by increasing the flow velocity in the pipe, the diameter of the flow path is changed by the joints at various places, cavitation is generated, thereby generating noise during water supply,
Although a water hammer occurs due to a sudden change in pressure due to the opening and closing of the faucet, noise is eliminated in the present invention because no joint is used for the water supply pipe 2, the hot water supply pipe 4, the water supply branch pipe 7, and the hot water branch pipe 8. Can be reduced.

Next, FIG. 7 shows a stainless steel joint 30 used for branching the water supply vertical pipe 1, which is attached to the intermediate pipe main body 31 by means of TIG welding on the upper and lower sides of the pipe main body 31. Socket pipes 32, 32, and a pipe body 31
And two female screw members 33, 33 attached thereto.

The female screw member 33 is a joint member having a tapered female screw for pipe formed on the distal end side and connected to the branch water supply pipe 11 of FIG. 1. The cylindrical member 31 is arranged so that two are located symmetrically on the same straight line. Is mounted in the mounting hole 34 by TIG welding.

A bulging portion 3 is provided at the tip of each of the socket tubes 32, 32.
2a is formed and the water supply riser 1 is connected, but the connection method is not limited to this, and various joining methods can be adopted.

As shown in FIG. 8, the water supply riser 1 is a unit riser 1a having a length corresponding to the floor height, and a joint 30 is provided on each floor.
Place it. At the time of piping, the unit standing pipe 1a and the joint 30 are brought into the site, and the unit standing pipe 1
It suffices to join the joints a with the joint 30 and connect the branch water supply pipes 11 to the left and right of the joint 30.

The above-described water supply standing pipe has the following advantages.

Conventionally, one or two T-joints and one socket were required for each floor, whereas the water supply vertical pipe of the present invention requires only one joint 30, so that the joint material cost and the connection work cost are required. Can be cheaper.

Conventionally, a standing pipe member and a joint had to be transported to a processing plant once, and a bulky member had to be transported many times in accordance with the progress of construction. Since it is sufficient to carry the joint 1a and the joint 30 to the site, all the conventional transportation and distribution costs are unnecessary, and the economical advantage is great.

The slab through hole of the water supply riser is the unit riser 1
The hole diameter for passing a is sufficient.

The above description has been made with reference to an example of an elevated water tank and an individual water heater. However, the present invention is not limited to this. It is needless to say that the present invention can be applied to other apartment houses provided with the above.

[0071]

Since the present invention has the above configuration, the following effects can be obtained.

(1) Water supply / hot water supply pipe, distribution header, water supply / hot water supply
Since the hot water supply branch pipe is arranged on the ceiling, it can be easily applied to a straight floor type which cannot be piped under the floor.

(2) On each floor, a water supply pipe is directly branched to a piping system, and a water supply pipe and the like are directly connected. Therefore, it is not necessary to install a water supply header on each floor, and the water supply pipe to each house is shortened. Thus, the members can be simplified and saved, and the labor for mounting and piping can be saved.

(3) Since the water supply pipe and the hot water supply pipe are integral stainless steel pipes that rise along the outer surface of the wall and along the ceiling, they can be piped to the ceiling simply by being inserted from outside the wall. Work becomes extremely easy.

(4) Since the water supply pipe and the hot water supply pipe are integrally formed stainless steel pipes without using a joint, there is no danger of water leakage and no water leakage test is required. Together, the construction is easy and the construction period can be shortened.

(5) Since the water supply branch pipe and the hot water supply branch pipe are integral soft stainless steel pipes without using joints, they can be bent by hand, and there is no danger of water leakage, and no water leakage test is required. And the construction period can be shortened.

(6) By using a stainless steel tube,
There is almost no oxidation, no red water or blue water is generated, and extremely sanitary water can be supplied. Furthermore, there is an advantage that the hardness and tensile strength are excellent, there is no damage during construction, and the diameter of the steel pipe can be reduced with a small friction loss.

(7) The water supply riser is composed of a unit riser, and the unit riser is joined by a joint in which a socket tube and a plurality of female threads are integrally formed, so that the number of members is reduced and work becomes easier. Thereby, the cost of the joint material and the cost of the connection work can be significantly reduced. In addition, transportation costs and distribution costs as in the related art are not required, and the economic merit is great.
