DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an eaves gutter suitable for use in ash-fall areas.

[0002]

2. Description of the Related Art In an area where ash falls, volcanic ash accumulates in the eaves gutter, and the volcanic ash becomes sludge-like due to the inclusion of rainwater. It often happens that it falls off without enduring it.

Conventionally, in order to prevent dead leaves or dust from entering the eaves gutter, for example, Japanese Utility Model Publication No.
As described in Japanese Patent No. 5289, wire mesh is put on eaves gutters. Therefore, it is conceivable to adopt a technique for preventing the intrusion of volcanic ash into the eaves gutter by adopting the above technology in the ash fall area.

[0004]

However, according to the above-mentioned means, volcanic ash penetrates into the eaves gutter through the mesh of the wire mesh, and the mesh of the wire mesh is clogged with the volcanic ash, so that the volcanic ash accumulates on the wire mesh. As a result, there is a problem that rainwater cannot flow into the eaves gutter.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an eaves gutter which does not stop rainwater due to the accumulation of volcanic ash and does not fall off due to the load of volcanic ash and rainwater. .

[0006]

In order to achieve the above object, in the eaves gutter of the present invention, a primary gutter having a groove formed by a bottom wall and a side wall and having a dropout formed in the bottom wall is provided. A secondary gutter provided inside the primary gutter and formed in a groove shape with a bottom portion narrower than the bottom wall and a side portion lower in height than the side wall, and a bottom wall of the primary gutter; A secondary gutter receiving member that supports the secondary gutter while securing a gap between the secondary gutter and the bottom of the secondary gutter, wherein the secondary gutter is formed to have a water gradient, The underwater end of the gutter is disposed near a drop of the primary gutter. In this eaves gutter,
It is preferable to provide an inclined plate that guides rainwater to the outlet at the lower end of the secondary gutter.

[0007]

In the eaves gutter according to the first aspect of the present invention, since the secondary gutter is formed shallower than the primary gutter, the volcanic ash that has entered the secondary gutter is easily blown off by the wind and accumulates on the secondary gutter. hard. In addition, the volcanic ash that has been deposited on the secondary gutter without being blown off by the wind mixes with the rainwater collected in the secondary gutter and flows down the inside of the secondary gutter from the upper side to the lower side,
It flows down from the lower end of the water and flows into the outlet of the primary gutter. This removes volcanic ash from the secondary gutter.

When the amount of rainwater is large, the rainwater overflows into the primary gutter and then flows into the outlet. That is, the rainwater overflows into the primary gutter after the volcanic ash has been removed from the secondary gutter, so that rainwater having a low volcanic ash content flows into the primary gutter.

Further, in the eaves gutter according to claim 2 of the present invention, the volcanic ash deposited on the secondary gutter mixes with the rainwater collected in the secondary gutter, and the inside of the secondary gutter is directed from the upper side to the lower side. Flowing down,
It is guided by the inclined plate provided at the lower end of the water and flows into the drop. In other words, the rainwater mixed with volcanic ash can be poured into the outlet without being scattered.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a sectional view showing a construction state of an eaves gutter according to an embodiment, and FIG. 2 is an explanatory diagram of a construction procedure of an eaves gutter according to the embodiment.

The eaves gutter of this embodiment comprises a primary gutter 1 and a secondary gutter 2
And the secondary gutter receiver 3.

The primary gutter 1 is formed in a groove shape with a bottom wall 1a, a front side wall 1b and a rear side wall 1c, and a drop opening 1d is formed in the bottom wall 1a. Further, the primary gutter 1 is fixed to an eave sky fixing bracket 5 via an eave gutter fixing bracket 4, and is disposed so as to be located directly below a tip of the roofing material 6. The drop opening 1d is provided with a dust cover 1e.

The secondary gutter 2 has a bottom 2a having a width smaller than the bottom wall 1a of the primary gutter 1, a front side 2b having a height lower than a front wall 1b of the primary gutter 1, and the primary gutter 1 having a lower height. And a rear side portion 2 c having a height lower than the rear side wall 13, and is formed in a groove shape and provided inside the primary gutter 1. The secondary gutter 2 is provided close to the front wall 1b of the primary gutter 1, and a gap is provided between the front wall 1b of the primary gutter 1 and the front side 2b of the secondary gutter 2. ing.

Further, the secondary gutter 2 is shown in FIGS.
As shown in the figure, is formed to have a water gradient θ,
The underwater end is disposed near the drop 1d of the primary gutter 1. A stop 2d is fixed to the upper end of the water, and an inclined plate 2e for guiding rainwater to the outlet 1d of the primary gutter 1 is fixed to the lower end of the water.

The side surface of the inclined plate 2e is in contact with or close to the front side wall 1b and the rear side wall 1c of the primary gutter 1.
The rainwater flowing down the inclined plate 2e is prevented from flowing down to the bottom wall 1a of the primary gutter 1 from the side of the inclined plate 2e. In addition, a gap 2f is provided below the inclined plate 2e so as not to prevent rainwater collected in the primary gutter 1 from flowing into the outlet 1d. Further, the inclined plate 2e
The lower end of the frame member 1 is provided on the periphery of the dropper 1d.
g. That is, the two secondary gutters 2 installed with the drop 1d interposed therebetween are connected via the inclined plate 1e and the frame member 1g.

As shown in FIG. 2, the secondary gutter receiver 3 fixes a support plate 31 for supporting the secondary gutter 2 and a front side 2b of the secondary gutter 2 to the support plate 31. It is composed of a holding piece 32 and a fixing piece 33 for fixing the support plate 31 to the eaves cover receiving member 7. The support plate 31 has a step 311, and in order to secure a gap between the bottom wall 1 a of the primary gutter 1 and the bottom 2 a of the secondary gutter 2, the primary gutter 1 is formed by the step 311. I support it.
The pressing piece 32 is formed of an elongated spring plate, and one end is fixed to the upper end of the support plate 31 so as to be vertically oriented. Further, the fixing piece 33 is formed of an elongated spring plate, and a middle portion is fixed to an upper end of the support plate 31 so as to be horizontal. In addition, it is preferable that the secondary gutter receiver 3 is formed of stainless steel in consideration of the acidity of the volcanic ash.

Referring to FIG. 2, the construction procedure of the eaves gutter will be described. First, install the secondary gutter receiver 3 on the primary gutter 1,
Both ends of the fixing piece 33 of the secondary gutter receiving member 3 are bent forward to fix the secondary gutter receiving member 3 to the eaves cover receiving metal member 7 (i). Next, the secondary gutter 2 is placed on the support plate 31 of the secondary gutter receiver 3.
Is installed, and the presser piece 32 of the secondary gutter receiver 3 is bent downward to fix the secondary gutter 3 to the support plate 31 of the secondary gutter receiver 3 (ii). In addition, it is preferable that the secondary gutter receivers 3 are installed at substantially constant intervals in the longitudinal direction of the primary gutter 1.

After attaching the eaves gutter in this way, a drain 9 is provided at the tip of the base plate 8 so as to cover the gap between the base plate 8 and the rear side 2c of the secondary gutter 2. The gap between the drainer 9 and the rear side wall 1c of the primary gutter 1 is closed with an eave gutter cover 10, and the gap between the eaves cover 11 and the front side 2b of the secondary gutter 2 is closed with an eave gutter cover 12. .

Next, the operation of the embodiment will be described.

In the eaves gutter of the present embodiment, since the gap between the base plate 8 and the rear side 2c of the secondary gutter 2 is covered by the drainer 9, volcanic ash cannot directly enter the primary gutter. Instead, it enters the secondary gutter 2. Also, all the rainwater flowing down from the roofing material 6 flows into the secondary gutter 2.

On the other hand, since the secondary gutter 2 is formed shallower than the primary gutter 1, the wind can be easily blown. Therefore, the volcanic ash that has invaded the secondary gutter 2 is easily blown off by the wind and hardly accumulates on the secondary gutter 2.

The volcanic ash deposited on the secondary gutter 2 without being blown off by the wind mixes with the rainwater collected in the secondary gutter 2 and directs the inside of the secondary gutter 2 from the upper side to the lower side. Then, the water is guided by the inclined plate 2e provided at the lower end of the water, and flows into the outlet 1d of the primary gutter 1. As a result, the volcanic ash is removed from the secondary gutter 2.

If the amount of rainwater is large, the rainwater is
And flows into the outlet 1d. That is, the rainwater overflows to the primary gutter 1
Since the volcanic ash has been removed from the water, rainwater having a low volcanic ash content flows into the primary gutter 1. Further, since the gap between the drainer 9 and the rear side wall 1c of the primary gutter 1 is closed by the eaves gutter cover 10, the rainwater overflowing to the primary gutter 1 does not overflow to the outside of the primary gutter 1 further. Absent.

That is, in the eaves gutter of the present embodiment, the absolute amount of volcanic ash deposited on the secondary gutter 2 can be reduced, and rainwater containing a large amount of volcanic ash does not flow into the primary gutter 1. Therefore, the rainwater is not stagnated by the accumulation of volcanic ash and does not fall off due to the load of the volcanic ash and the rainwater. In addition, since the rainwater mixed with volcanic ash can be poured into the outlet 1d of the primary gutter 1 without scattering, the primary gutter 1 is not stained with the volcanic ash.

Further, by forming a primary gutter with an existing eaves gutter, it can be easily applied to an existing building.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention. For example, in the embodiment, the secondary gutter receiver having a structure for supporting the secondary gutter from below is used, but a secondary gutter receiver having a structure for suspending the secondary gutter from above may be used. Further, in the embodiment, the secondary gutter receiving member is fixed to the eaves cover receiving member, but the secondary gutter receiving member may be fixed to the primary gutter if the primary gutter is firmly fixed to the building. Further, a fixing tool such as a rivet or a screw may be used as a means for fixing the secondary gutter receiving tool. Further, in the embodiment,
The construction example in which the eaves gutter was covered with eaves and eaves covers was shown, but the eaves gutter may be left exposed.

[0027]

As described above, in the eaves gutter according to claim 1 of the present invention, the absolute amount of volcanic ash deposited on the secondary gutter can be reduced, and the content of volcanic ash in the primary gutter can be reduced. Since it is possible to prevent heavy rainwater from flowing in, it is possible to obtain the effect of preventing the rainwater from being accumulated due to the accumulation of volcanic ash and falling without being able to withstand the load of the volcanic ash and the rainwater.

Further, in the eaves gutter according to the second aspect of the present invention, since rainwater mixed with volcanic ash can be poured into the outlet without being scattered, the effect that the primary gutter is not stained with the volcanic ash can be obtained. .
