Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage equipment reforming structure.

[0002]

2. Description of the Related Art In a toilet drainage system as shown in FIGS. 2A and 2B, when an existing drainage pipe 51 is deteriorated and needs to be reformed, conventionally, an existing old water distribution pipe 51 is removed. It has been done to replace it with a new drain. 52 is a pipe space, 54 is a toilet bowl, and 55 is a horizontal draw pipe.

However, in some buildings, the drain pipe 5
In some cases, pipes 1 are inseparably connected to the building frame. In such a case, it is necessary to break a part of the frame, and replacement of drainage pipes is a large and costly renovation work. Sometimes.

[0004] In addition, in an apartment house or the like, the drain pipe 51 often passes through a dwelling unit downstairs, so that it is difficult to obtain an agreement for replacement work due to cost and other factors. Not a few.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a drainage equipment reforming structure that can easily and cost-effectively perform drainage equipment reforming work. .

[0006]

The object of the present invention is to provide an existing drainage pipe as a sheath pipe, through which a new drainage pipe for drainage is passed, and to which a vacuuming device is connected. The problem is solved by the characteristic drainage equipment reform structure.

[0007] This remodeling structure is intended to effectively utilize an old drainage pipe as a guide pod for passing a new drainage pipe without removing it. Therefore, there is no need to remove the old drainage pipe, and the new drainage pipe can be installed by passing the existing drainage pipe as a guide pipe. Renovation work of drainage equipment can be performed simply and advantageously in terms of cost.

In addition, since a vacuum device is connected to the new water pipe, a sufficient drainage capacity can be maintained even if a water pipe having a diameter smaller than that of the existing water pipe is used as the new water pipe. Can be. In addition, since vacuum drainage is performed by evacuation, a new drain pipe must be provided with a water gradient, etc.
There's no need to bother with the natural flow method,
Renovation work can be carried out more easily.

In the above-mentioned remodeling structure, by making the new drainage pipe a flexible pipe, the new drainage pipe can be easily passed through the existing water distribution pipe in construction. In addition, the formation of the pipe at the bent portion can be dealt with by bending the flexible pipe, and it is possible to eliminate troublesome work such as providing a bent pipe. In addition, the drainage gradient, which is a problem when adopting the natural flow method for flexible pipes, can be eliminated by connecting a vacuuming device, and flexible pipes can be effectively used as new drainage pipes. it can.

[0010]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a renovation structure of a drainage system of a toilet provided in an upper floor of a detached house or an apartment house. In the figure, reference numeral 1 denotes an existing old drainage vertical pipe, and the drainage vertical pipe 1 extends in a pipe space 2 in a vertical direction. The tube diameter is, for example, 75 to 100 mm. The reform is performed by using the old drainage vertical pipe 1 as a sheath pipe.

That is, a flexible pipe 3 as a new drain pipe is passed through the inside of the drain vertical pipe 1, and the flexible pipe 3 and the toilet 4 are communicated with each other by a horizontal pulling pipe 5 also made of a flexible pipe. The sewage from the toilet 4 of the toilet is sent to the flexible pipe 3 in the existing drainage vertical pipe 1 through the horizontal pulling flexible pipe 5 to be drained.

The flexible pipe 3 in the existing drainage vertical pipe 1 has a diameter smaller than the diameter of the drainage vertical pipe 1, for example, 40 mm, so that the flexible pipe 3 can be passed through the drainage vertical pipe 1. Since the drainage capacity is small, the drainage capacity is reduced by the natural flow method using only the flexible pipe 3. In order to supplement this, a vacuum evacuation device 6 is connected to the flexible pipe 3 passed through the existing drainage vertical pipe 1.

By driving the vacuuming device 6, sewage from the toilet is forcibly sent to the flexible pipe 3 in the existing drainage vertical pipe 1 through the horizontal pulling flexible pipe 5, and the drainage performance is inferior to the conventional one. can get.

Further, by connecting the vacuuming device 6, the drainage is of a vacuum drainage type. Therefore, as shown in FIG.
The horizontal flexible pipe 5 passes through the side wall 7 of the toilet without passing the flexible pipe 3 under the floor of the toilet.
Can be connected.

As described above, according to the above-described reform structure, a drainage system is formed through the flexible pipe 3 using the drainage vertical pipe 1 as a sheath without removing the existing drainage vertical pipe 1. Renovation work of the drainage equipment can be performed easily and easily, and the cost required for repair work can be kept low. Moreover, since the flexible pipe 3 is used as a new drain pipe, the new drain pipe can be easily passed through the existing drain pipe 1.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, the renovation structure of the drainage facility for draining sewage from the toilet is shown, but the renovation structure of the present invention is applied to various types of water around the washroom, bathroom, shower room, kitchen, etc. It may be widely applied as a reform structure of a drainage facility.

[0018]

As described above, according to the renovation structure of the drainage system of the present invention, the existing drainage pipe is used as a sheath pipe, a new drainage pipe for drainage is passed through the inside thereof, and the drainage pipe is evacuated to a vacuum device. Is connected, it is possible to eliminate the need for large-scale construction to remove the old drainage pipe, and to install the new drainage pipe using the existing drainage pipe as a guide pipe. The drainage can be easily performed, and the renovation work of the drainage facility can be easily performed, and the cost required for the repair work can be reduced. Of course, since the new water distribution pipe is connected to the evacuation device, the drainage performance is not impaired even if the diameter of the new drainage pipe is small.
Therefore, even when the existing drainage pipe is inseparable from the building frame, the drainage facility can be easily renovated. Even if the water is passed through the drainage system, the drainage can be renovated without difficulty.

Furthermore, by making the new drainage pipe a flexible pipe, the new drainage pipe can be easily passed through the existing water distribution pipe for construction. Also,
This can be easily handled by bending the flexible pipe even in the pipe to the bent part, and in connection with the adoption of the vacuum evacuation device, the structural restriction in the natural flow method can be eliminated and the flexible The pipe can be effectively used as a new drain pipe.
