TECHNICAL FIELD The present invention relates to a drainage device applied to a building.

(Prior Art) As a drainage device that has been conventionally applied to a building, for example, one described in Japanese Utility Model Publication No. 56-31631 is known.

In this conventional device, eaves troughs for guiding rainwater to the downspout are provided along the edge of the roof plate, and further, a draining plate for guiding rainwater overflowing from the eaves to the outside is provided below the eaves trough. The draining plate is provided so as to project outside the outer wall so that rainwater can be discharged to the outside along the surface of the outer wall.

(Problem to be Solved by the Invention) However, in such a conventional drainage device, since the draining plate is provided so as to project outward from the outer wall, the draining plate and the front surface of the eaves gutter are covered. The provided parapet had to be provided at a position protruding outward from the outer wall panel through the drainage gap. The appearance of the building was impaired by the protrusion of the parapet and the drainage gap between the parapet and the outer wall.

The present invention focuses on the above-mentioned problems, and makes it a common task to develop a drainage device that can provide a parapet without protruding outward from an outer wall. In addition, the development of a drainage system that enables residents to easily detect an abnormal situation when a downflow gutter is clogged with dust or the like occurs.

(Means for Solving the Problem) In order to solve the above problems, the drainage device of the present invention has a drainage channel formed by an eaves trough, a funnel, and a vertical gutter, and the eaves trough is located on the indoor side from the back surface of the outer wall. A primary gutter provided along the edge of the roof board so as to receive rainwater from the roof board, and a primary gutter provided below the primary gutter to receive rainwater overflowing from the primary gutter. And a secondary gutter, and the funnel is arranged at a position for receiving the rainwater from the primary gutter and the secondary gutter, and the funnel normally drains rainwater from the primary gutter to a vertical gutter. Is formed,
It is characterized by the formation of an emergency drain for draining rainwater from the secondary gutter directly to the outside.

(Operation) In the drainage device of the present invention, the rainwater that flows down along the roof plate first flows into the primary gutter first, then flows into the funnel from the primary gutter, and then from the normal drainage port through the vertical gutter to the outside. Be drained to.

In addition, when the amount of rainwater flowing into the primary gutter due to heavy rain exceeds the allowable drainage amount of the primary gutter, in an abnormal case where the rainwater overflows from the primary gutter, the overflowed rainwater flows into the secondary gutter. It flows into the funnel from the secondary gutter and drains directly to the outside from the emergency drain.

(Example) Hereinafter, an example 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 described.

As shown in FIG. 2, the drainage device of this embodiment is applied to a building having no flaws. A drainage channel is formed by the funnel 3 provided at the end of the funnel 3 and the vertical gutter 4 connected to the bottom of the funnel 3.

The origami plate 1 is provided with a slight gradient and is supported by the tight frame 5.

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

The eaves gutter 2 is separated by a partition plate 21 into an upper primary gutter 22 and a lower secondary gutter 23. The primary gutter 22 receives rainwater from the folding plate 1 and the secondary gutter 23 separates the primary gutter 22 from the primary gutter 22. It is arranged to receive the overflowing rainwater. Also, the partition plate
The rainwater overflowed from the primary gutter 22 was drained to the secondary gutter 21.
An outlet 211 leading to 23 is opened.

The primary gutter 22 and the secondary gutter 23 are provided in parallel with each other with a slope, and are arranged on the indoor side from the back surface of the outer wall 8. In addition, the allowable amount of drainage is secured by the secondary gutter 23 exceeding the primary gutter 22.

Further, the primary gutter 22 is covered with a dust-preventing net to cover its upper surface.
24 are provided.

9 is a parapet, which is located above the outer wall 8
And are continuously provided on the same plane. The outer wall 8 is a roof beam
It is fixed to the support frame 11 via the support frame 11, while the parapet 9 is also fixed to the support frame 11.

Brick tiles are used horizontally on the outer wall 8, and brick tiles are used vertically on the parapet 9.

In addition, the parapet 9 is provided with a through hole 91 for penetrating the downstream end portions of the primary gutter 22 and the secondary gutter 23 to the outside, and the funnel 3 has a primary gutter protruding from the through hole 91. It is provided so as to cover the downstream end portions of 22 and the secondary gutter 23.

Further, the funnel 3 is horizontally divided by a partition plate 31 into a first water collecting section 32 into which rainwater from the primary gutter 22 flows and a second water collecting section 33 into which rainwater from the secondary gutter 23 flows. Has been done. A normal drainage port 34 connected to the downspout 4 is provided at the bottom of the first water collecting portion 32, and a side wall of the first water collecting portion 32 has a first emergency opening to the outside. A drainage port 35 is provided. In addition, a second emergency drain port 36 that is opened to the outside is provided at the bottom of the second water collecting portion 33.

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 described.

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

[Normal time] First, the rainwater that runs down along Origami plate 1 should be covered with a dust net 24.
After the leaves and pebbles have been removed by, it flows into the primary gutter 22. Then, it flows through the primary gutter 22 and the first water collecting part of the funnel 3
It flows into 32 and is normally discharged from the drainage port 34 through the vertical gutter 4 to the outside (see the solid arrow in the figure).

[Drainage gutter abnormalities] If the drainage function of the downflow grate 4 is impaired due to clogging of debris, rainwater flowing from the primary gutter 22 into the first water collecting part 32 of the upper joint 3 will be discharged to the first emergency drainage port 35. Is directly discharged from the outside (see the one-dot chain line arrow in the figure).

Here, since the first emergency drainage port 35 is provided at a position lower than the upper end of the partition plate 31 in the funnel 3, rainwater will pass over the partition plate 31 and the first water collecting section 32 to the second water collection unit. It is designed to drain to the outside before flowing into the part 33.

[When the primary gutter is abnormal] When the amount of rainwater flowing into the primary gutter 22 due to heavy rainfall exceeds the allowable drainage of the primary gutter 33, or when dust is blocked on the dust blocking net 24 and cannot flow into the primary gutter 22. However, when the rainwater overflows from the primary gutter 22, the overflowed rainwater flows into the secondary gutter 23 through the outlet 211 of the partition plate 21. Then, it flows through the secondary gutter 23 and the funnel 3
Flows into the second water collecting section 33 and is directly discharged to the outside from the second emergency drain port 36 (see the dotted arrow in the figure).

As described above, according to the drainage device of this embodiment, since the rainwater is drained from the first emergency drainage port 35 of the funnel 3, an abnormality in the downspout 4 can be recognized, and the rainwater is drained from the second emergency drainage port 36. Since the water is drained, the abnormality of the primary gutter 22 can be recognized.

Then, by concentrating the drainage of the rainwater at such an abnormal time to the first emergency drainage port 35 or the second emergency drainage port 36, it is easy to find it from the outside. As a result, the resident can take measures such as maintenance at an early stage.

Moreover, since the surface of the parapet 9 and the surface of the outer wall 8 are substantially continuous with each other without making the parapet 9 project forward from the outer wall 8, the appearance is also excellent.

The embodiment of the present invention has been described in detail above with reference to the drawings.
The specific configuration is not limited to this embodiment, and the present invention includes a design change and the like within a range not departing from the gist of the present invention.

For example, in the embodiment, the rainwater flowing into the funnel from the secondary gutter is configured to be drained directly from the emergency drain port to the outside, but it may be drained to the vertical gutter from the normal drain port. In that case, it is desirable to expand the allowable drainage of the funnel and downspout.

Although the rainwater is drained to the outside from the second emergency drainage port when the vertical gutter is abnormal, the rainwater may be drained from the first emergency drainage port to the outside without providing the second emergency drainage port.

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

In the drainage device of the present invention, since the eaves gutter is disposed on the indoor side from the rear surface of the outer wall, it is possible to provide the parapet without protruding outward from the outer wall, and the surface of the parapet and the surface of the outer wall. The outer appearance can be improved by, for example, making them continuous on substantially the same surface.

Furthermore, when an abnormality occurs, rainwater is intensively drained directly from the emergency drain of the funnel to the outside, so that the resident can easily find out the abnormality and can quickly perform maintenance and other processing. .
