Abstract

PURPOSE:To improve the drainage efficiency by providing a water splash preventing plate for catching water flowing through a valley part and guiding the same to the edge of the eaves on the edge of the eaves end area of the valley part of a roof. CONSTITUTION:A water splash preventing plate 8 comprises an insert part 9 fixed to a sheathing plate 6 or the like, a vertical wall part 10 for catching rain water and guiding the same to an eaves gutter 7 and a water return part 11 for preventing rain water which collides with the vertical wall part 10 from splashing upward. Rain water flowing on a valley gutter 4 is caused to collide with the vertical wall part 10 of the water splash preventing plate 8, thereby dividing the water to the right and left to be guided along the edge of the eaves and let fall in the eaves gutter 7. Accordingly, the rain water can be prevented from being splashed from the inside of the eaves gutter to the outside almost completely.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water splashing device in a roof valley.

[0002]

2. Description of the Related Art FIG. 5 is a plan view of a roof 21 in a house or the like, in which an arrow C indicates the flow direction of the roof 21. As shown in the figure, the roof 21 is provided with a valley portion 22, and the valley portion 22 is constituted by a valley plate 24 stretched on an asphalt roofing 23 as shown in FIGS. 6 and 7. Tani gutter 25 is provided, and eaves gutter 26 is provided in the eaves part, and it is configured to collect rainwater flowing on the roof surface that constitutes the valley part 22 into the gutter 25 and flow it to the eaves gutter 26. There is.

When a large amount of rainwater flows into the trough 25, there is a problem that the rainwater violently collides with the inner surface of the eaves gutter 26 and bounces off, and is scattered from the inside to the outer side of the eaves gutter 26. Conventionally, as shown by the phantom line in FIG.
Protrusion 27 is made of caulking material on the upper surface of
As shown in FIG. 8, it is possible to reduce the flow rate of rainwater flowing through the rainwater 25, or as shown in FIG.
Have been set up.

[0004]

In the case where the projection 27 is provided on the upper surface of the valley plate 24, there are variations in construction,
The effect of weakening the flow velocity is not reliable, and even if the rainwater scattering prevention member 28 is provided, it is not possible to completely prevent the rainwater from scattering from the inside to the outside of the eaves gutter 26.

In both cases, rainwater is drained into the gutter.
Since it directly drops from 25 to the eaves gutter 26, rainwater is intensively dropped from the valley gutter 25 into the eaves gutter 26, and swirls in the eaves gutter 26 as it is, so there is also a problem of poor drainage efficiency. Therefore, it is an object of the present invention to improve the effect of preventing water from scattering from the inside of the eaves gutter to the outside, and to improve the drainage efficiency of water flowing in the eaves gutter.

[0006]

[Means for Solving the Problems] The technical means taken by the present invention to achieve the above-mentioned object is to provide an eaves end by receiving water flowing in the valley 1 at the eaves side end of the valley 1 of the roof. There is a water splash prevention plate 8 that guides the eaves gutter 7 along.

[0007]

[Operation] Rainwater flowing through the valley part 1 of the roof is once received by the water splash prevention plate 8 at the edge of the eaves side of the valley part 1 and is guided to the eaves gutter 7 along the eaves side. The dropped rainwater is efficiently discharged in the flow direction, so that it does not scatter from the inside to the outside of the eaves gutter 7.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the eaves side of the valley 1 of the roof, 2 is the roofing material, and 3 is the valley plate that forms the trough 4. As shown in Fig. 2, the valley plate 3 is formed from a copper plate or an iron plate to have a V-shaped cross section in accordance with the shape of the valley portion 3, and is stretched over the asphalt roofing 5 from the ridge to the eaves, and the suspension is attached. It is fixed to the base plate 6 through. In addition, there is a eaves gutter 7 at the eaves.

A water splash prevention plate 8 is provided at an end of the valley portion 3 on the eaves side to receive rainwater flowing through the trough 4 and guide it to the eaves 7. This water splash prevention plate 8
As shown in FIG. 2 and FIG. 3, an insertion portion 9 that is inserted between the valley plate 3 and the asphalt roofing 5 and fixed to the ground plate 6 and the standing wall that receives rainwater and guides it to the eaves gutter 7. It comprises a part (10) and a water return part (11) for preventing rainwater hitting the standing wall part (10) from splashing upward.

FIG. 4 is a plan view showing a developed state of the water splash prevention plate 8, in which a dotted line shows a broken line and 12 shows a cut line.
The insertion portion 9 is valley-folded along the polygonal line ab to form a V-shape that matches the shape of the valley portion 1. The standing wall portion 10 has polygonal lines bc and bd.
It is folded in a valley and is also mountain-folded along the polygonal line be.
It is formed in a V-shape in plan view that matches the shape of the corner of the eaves side end. The water return portion 11 is valley-folded along the polygonal lines ce and ed.

In the above structure, the rainwater flowing on the trough 4 hits the standing wall portion 10 of the water splash prevention plate 8, where it is divided into left and right and guided along the eaves to the eaves gutter 7. Dropped. Water droplets that hit the standing wall portion 10 and try to fly upward hit the water return portion 11 and are prevented from splashing. In the case where the rainwater splash prevention member 28 as shown in FIG. 8 of the conventional example is provided on the upper end of the outer wall of the eaves trough 26, the spatter prevention member 28 cannot be attached depending on the model of the eaves trough 26 used. (Or, there is no product lineup.) However, in the above-mentioned embodiment, the water splash prevention plate 8 is made of sheet metal and has a structure inserted between the trough plate 3 and the asphalt roofing 5. , It can be attached to any valley 1.

[0012]

According to the present invention, the water flowing in the valley 1 is once received by the water splash prevention plate 8 and then guided to the eaves gutter 7 along the eaves edge, so that the eaves gutter 7 from the inside to the outside. Water can be almost completely prevented from splashing into the eaves gutter 7, and the water that has fallen inside the eaves gutter 7 flows efficiently in the flow direction.
