Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a drainage device applied to buildings.

(Prior Art) Conventionally, as a drainage system applied to buildings, there is known a system as described in, for example, Japanese Utility Model Publication No. 56-31631.

In this conventional device, an eaves gutter is provided along the edge of the roof panel to guide rainwater to the downspout, and a drain plate is further provided below the eaves gutter to guide rainwater overflowing from the eaves gutter to the outside.

This drainage board was provided so as to protrude outward from the outer wall so that rainwater would run along the surface of the outer wall and be drained to the outside.

(Problem to be solved by the invention) However, in such a conventional drainage device,
Because the draining board was installed to protrude outward from the exterior wall, the parapet that was installed to cover the front of the draining board and eaves gutter had to be installed at a position that protruded outward from the exterior wall panel through the drainage gap. I didn't get it. The beauty of the building was spoiled by the protrusion of the parapet and the drainage gap between the parapet and the exterior wall.

The present invention has focused on the above-mentioned problems, and has as its common objective the development of a drainage device that can provide a loose bed without protruding forward from the outer wall.

In addition, we also aim to develop a drainage system that allows residents to easily detect an abnormal situation, such as when a downspout becomes clogged with debris.

(Means for Solving the Problems) In order to solve the above problems, in the drainage device of the present invention, a drainage channel is formed by an eaves gutter, an upper base, and a downpipe, and the eaves gutter is directed toward the indoor side from the back surface of the outer wall. There is also a primary tank provided along the edge of the roof shingles to receive rainwater from the roof shingles, and a primary tank located below the primary tank to receive rainwater that overflows from the secondary tank. It consists of a secondary tank installed in
Further, the upper stand is disposed at a position to receive rainwater from the secondary tank and the secondary tank.

Furthermore, in the upper case, a normal drain is formed to drain rainwater from the secondary tank to the downpipe, and an emergency drain is formed to drain rainwater from the secondary tank directly to the outside. desirable,.

(Function) In the drainage device of the present invention, rainwater flowing down along the roof plate normally flows into the secondary tank, and from this secondary tank, flows into the upper case.

In addition, the amount of rainwater that flows into the primary tank due to heavy rain.

- In abnormal situations where rainwater overflows from the primary tank, such as when the allowable drainage volume of the secondary tank is exceeded, the overflowing rainwater flows into the secondary tank, and from this secondary tank flows into the upper case.

Furthermore, the amount of water discharged according to claim 2 (9L: 1- is the IT1 water cj-1 normal drainage [] that has flowed into the upper case from the -2 tank) and is drained to the outside through the downspout. Rainwater flowing into the upper tank from the next tank is drained to the outside from the emergency drain.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the structure of the embodiment shown in FIGS. 1 to 4 will be explained.

The drainage system of this embodiment is particularly applied to buildings without eaves, as shown in Fig. 2, and includes an eaves gutter 2 provided along the edge of the An upper stand 3 provided at the end and a downpipe 4 connected to the bottom of the upper stand 3

In addition, 6 is a side door, and 7 is a draining board.

The eaves gutter 2 is divided into an upper primary tank 22 and a lower secondary tank 23 by a partition plate 21. The secondary tank 22 receives rainwater from the folding plate 1, and the secondary tank 23 collects the rainwater It is arranged to catch rainwater that overflows from 22. Also,
The partition plate 21 has an opening 211 for guiding rainwater overflowing from the secondary tank 22 to the secondary tank 23.

The secondary tank 22 and the secondary tank 23 are provided parallel to each other with a slope, and are arranged toward the indoor side from the back surface of the outer wall 8.Also, the allowable drainage amount is the same as that of the primary tank for the secondary tank 23. It has been secured in excess of 22.

Further notes - next tank 2? A stone dust stopper w424 is installed to cover the top surface.

Reference numeral 9 denotes a parabet, which is continuously provided above the outer wall 8 on the same plane as the outer wall 8. The parabet 8 is connected to the roof beam 1.
0 via a support frame 11, and the rosette 9 is also fixed to the support frame 11.

In addition, brick tiles are used for the outer wall 8 horizontally, and brick tiles are used vertically for the rose bed 9.

Further, the bulk bed 9 is provided with a through hole 91 that extends through the downstream ends of the secondary tank 22 and the secondary tank 23 to the outside, and the upper stand 3 is provided with a through hole 91 of 5:. The downstream end portions of the primary tank 22 and secondary tank 23 protruding from the tank are covered with each other.

Also, this upper stand 3 is horizontally connected to a first water collection part 32 into which rainwater from the secondary tank 22 flows in through the partition plate 3] and a second water collection part 33 into which rainwater from the secondary tank 23 flows. It is divided into. A normal drain port 34 connected to the downpipe 4 is provided at the bottom of the first water collection section 32, and a first emergency drain port 34 which is opened to the outside is provided at the side wall of the first water collection section 32. A drain port 35 is provided. In addition, the second water collecting section 33
A second emergency drain port 36 opened to the outside is provided at the bottom of the tank.

Note that the first emergency drain port 35 is provided at a position lower than the upper end of the partition plate 31.

Next, the operation of the embodiment will be explained.

First, the flow of rainwater will be explained with reference to FIG.

[Normal times] Rainwater flowing down along the folding plate 1 first passes through the garbage stopper net 24.
After fallen leaves, pebbles, etc. are removed, the water flows into the secondary tank 22. The water then flows through the secondary tank 22, flows into the first water collection part 32 of the upper platform 3, and is drained to the outside through the downpipe 4 from the normal drain port 34 (see the solid line arrow in the figure).

[When the downspout is abnormal] If the downspout 4 has lost its drainage function due to clogging with garbage, etc., the rainwater that has flowed from the secondary tank 22 into the first water collection part 32 of the upper platform 3 is diverted to the first emergency drain 35. The water is drained directly to the outside (see the dashed-dotted line arrow in the figure).

Here, the first emergency drainage port 35 is provided at a lower position than the upper end of the partition plate 31 in the upper case 3, so that rainwater flows over the partition plate 3I from the first water collection part 32 to the second collection part. Water section 33
The water is drained outside before flowing into the water.

[When an abnormality occurs in the − secondary tank] ・The amount of rainwater flowing into the primary tank 22 due to heavy rain is
In abnormal situations, such as when rainwater overflows from the primary tank 22, such as when the allowable drainage volume exceeds the allowable drainage volume in step 3, or when trash accumulates on the trash net 24 and prevents it from flowing into the primary tank 22, the overflowing rainwater is removed from the partition. It flows into the secondary tank 23 through the drop port 211 of the plate 21. Then, it flows through the secondary tank 23, flows into the second water collection part 33 of the upper platform 3, and flows into the second water collection part 33 of the upper platform 3.
The water is drained directly to the outside from the emergency drain port 36 (see the dotted line arrow in the figure).

As described above, according to the drainage device of this embodiment, an abnormality in the downspout 4 can be recognized because rainwater is drained from the first emergency drain port 35 of the upper platform 3, and rainwater is drained from the second emergency drain port 36. An abnormality in the primary tank 22 can be recognized by the fact that the water is being drained.

The first step is to drain rainwater during abnormal times like this.
By concentrating on the emergency drain port 35 or the second emergency drain port 36, it is easier to discover from the outside. This allows residents to take early steps such as maintenance.

Furthermore, since the parapet 9 does not protrude forward from the outer wall 8 and the surface of the parapet 9 and the surface of the outer wall 8 are continuous on substantially the same plane, the appearance is also excellent.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are design changes within the scope of the gist of the present invention, they are included in the present invention. It will be done.

For example, in the example, rainwater flowing from the secondary tank to the upper case is
Although the system is configured so that the water is drained directly to the outside from the emergency drain, the water may be drained from the normal drain to the downspout.

In that case, it is desirable to increase the permissible displacement of the upper and downspouts.

In addition, in the event of an abnormality in the downspout, rainwater was drained to the outside from the second emergency drain, but without providing the second emergency drain,
The water may be drained to the outside from the first emergency drain port.

(Effects of the Invention) Since the drainage device of the present invention is configured as described above,
The following effects can be obtained.

In the drainage system according to claim 1, since the eaves gutter is arranged on the indoor side from the back side of the outer wall, the parapet can be provided without protruding forward from the outer wall, and the parapet surface and the outer wall are connected. The appearance can be improved by, for example, making the surfaces continuous on substantially the same plane.

In the drainage system of claim 2, in addition to the effects of claim 1, when an abnormality occurs, rainwater is intensively drained directly to the outside from the upper abnormality drainage port, so that residents can be relieved of the abnormality. It can be easily detected, and maintenance and other measures can be taken early.
