Abstract

PURPOSE:To localize the fouling of a front eave surface caused by rainwater, and to maintain a fine view by downward installing a drain board at the front end of a sheathing board and setting up a secondary drain board to the front eave surface under a projecting state through a subsequent mounting method. CONSTITUTION:An eave gutter 3 is supported to a supporter 2 fixed onto the side face of a front eave, and a drain board 1 is fitted downward at the front end of a sheathing board 5. A secondary drain board 4 is installed to a front eave surface under a projecting state through a subsequent mounting method. When rainwater flowing down from a roof board 10 collides with the side face of a front eave by flowing by a wind and jumping-up from the bottom wall 31 of the eave gutter 3, rainwater is guided by the secondary drain board 4, and flows down to a lower section. Accordingly, the fouling of a section lower than the secondary drain board 4 is prevented while a view from the lower section of the front eave of the fouling of an upper section can be made difficult.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a house eave structure and its construction method.

(Prior art) As a conventional eave structure, for example,
Those described in Japanese Utility Model Publication No. 26 and Japanese Utility Model Application Publication No. 62-75133 are known.

In these conventional eaves structures, supports are fixed to the fascia board at predetermined intervals, and the eaves gutter is supported by the supports. It is located in a convenient location.

In addition, in recent years, as the eaves have become smaller,
There is a tendency for the installation location of eaves gutters to be closer to the fascia board.

On the other hand, houses with white walls have become popular, and as a result, people's views on dirt have become stricter.

(Problem to be solved by the invention) However, in such a conventional eaves structure, rainwater that falls from the tip of the roof board splashes up at the bottom of the eaves gutter, and the splashed rainwater flows onto the walls of the house and This corresponds to the fascia board, etc. Additionally, there has been a problem in that the dust mixed in with the rainwater creates speckled or flowing patterns, spoiling the aesthetic appearance of the house.

Therefore, in order to reduce the splashing of rainwater, we installed a draining plate facing downward from the tip of the roof board, and the rainwater that falls from the tip of the roof plate flows through the draining plate and flows into the eaves gutter. There is also a structure.

In such an eaves structure, in order to reduce water splashing up, it is effective to bring the draining board and the bottom wall of the eaves gutter as close as possible to shorten the distance that rainwater falls. The more you do this, the more the draining board becomes an obstacle during the separation process, and the work efficiency becomes worse.

In this way, although installing a drain board can prevent splashing up to a certain extent, there is a limit to how close the drain board can be to the eaves gutter, so it may not be effective in cases of heavy rainfall. There wasn't. Therefore, it is not sufficient to reliably prevent rainwater from hitting the house, and the problem of the house being contaminated still remains.

In addition, the wind blowing on the fascia board passes through the gap between the drain board and the eaves gutter and blows up between the drain board and the fascia board, so when it rains, the rainwater that falls from the tip of the drain board is blown up by the wind. There was also the problem of hitting the fascia slopes and walls of houses.

The present invention focuses on the above-mentioned conventional problems, and provides an eaves structure and its construction method that can prevent the surface of the eaves from being soiled by rainwater splashed up in the eaves gutters or blown up by the wind. It is intended to.

(Means for Solving the Problems) In order to achieve the above object, the eaves structure of the present invention has a draining board facing downward at the tip of the roof board, and a predetermined position on the eaves surface of the wall, fascia board, etc. The structure is such that supports are fixed at intervals, and eaves gutters are supported by the supports, and a secondary drain plate is protruded from the surface of the eaves.

Similarly, in order to achieve the above object, the construction method of the eaves structure of the present invention is such that draining boards are provided facing downward at the tips of the roof panels, and the eaves surfaces of walls and fascia boards are provided at predetermined intervals. In this method, a secondary draining board is retrofitted in a protruding state on the eaves surface of an eaves structure in which a support is fixed to the support and an eaves gutter is supported on the support.

(Function) With the eaves structure of the present invention, rainwater that has fallen from the tip of the roof board is blown away by the wind and hits the eaves without falling into the eaves gutter.
Furthermore, if rainwater falls into an eaves gutter but bounces up from the bottom of the eaves gutter and hits the side of the eaves, the rainwater that hits the eaves will be guided to the secondary drainage board and flow downward.

Therefore, rainwater does not run down the portion of the eaves surface below the secondary draining plate, so that it is prevented from becoming contaminated by dust and the like mixed in the rainwater. Furthermore, even if the area above the secondary draining slope gets dirty due to rainwater, it is covered from below by the secondary draining plate.

Furthermore, in the method for constructing an eaves structure of the present invention, an eaves structure having the above-mentioned effects can be obtained by simply adding a secondary drain plate to the eaves surface of a conventional eaves structure.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

It is prevented from falling off. In addition, the ear part 34 of the eaves gutter 3.
When engaging the ear part 35 with the ear piece 221.222 of the support 2, the ear part 34.35 is pulled out with the ear piece 221.222 while elastically deforming the retaining piece 223.224. This is completed by pushing between the stopper pieces 223 and 224.

The secondary drainer 4 is an elongated member having an inverted cross section with a vertical piece 41 and an inclined piece 42, and the vertical piece 41 is adjacent to the lower side of the mounting rod 21 of the support 2. It is fixed to the decorative board 8. Further, the inclined pieces 42 of the secondary draining plate 4 are protruded from the rear wall 33 of the eaves gutter 3 with a gap 43 in between and facing each other.

The material of this secondary draining plate 4 may be a synthetic resin or a metal plate. Further, the molding methods include bender, drawing, extrusion, etc. Further, when fixing the secondary draining plate 4 to the decorative board 8, it is possible to fix it by adhesion, welding, rivets, etc.

Further, the secondary draining board 4 can be easily fixed to the decorative board 8 even after the support 2 is fixed to the fascia board 7 and the eaves gutter 3 is attached by the support. That is,
The above eaves structure can be obtained by simply adding the secondary draining board 4 to the conventional eaves structure. In addition, if the decorative board 8 in the conventional eaves structure is dirty, the paint is replenished on that part and then the secondary drainer 4 is attached afterwards.

Next, the operation of the first embodiment will be explained.

In the eaves structure of this embodiment, rainwater that flows down from the tip of the eaves tile 10 placed on the roof board 5 falls into the eaves gutter 3 through the drainer ff1l.

However, when there is a wind, the rainwater that has fallen from the tip of the eaves tile 10 may be blown away by the wind and hit the decorative board 8 instead of falling into the eaves gutter 3, or when there is a lot of rainfall, the rainwater that has fallen from the tip of the eaves tile 10 may fall off the tip of the eave tile 10. Rainwater that has fallen from the eaves often splashes up at the bottom of the eaves gutter 3 and hits the decorative board 8. In these cases, the rainwater that hits the decorative board 8 is guided by the inclined piece 42 of the secondary drainage board 4 and flows into the gap 43 between the rear wall 33 of the eaves gutter 3 and the secondary drainage board 4.
flows downward from.

Therefore, rainwater will not run down the lower part of the eaves surface of the decorative board 8 than the secondary drainer 4.
This prevents dirt from being contaminated by dust mixed with rainwater. In addition, even if the upper part of the secondary draining plate 4 becomes dirty due to rainwater, the secondary draining plate 4 will allow the area above the secondary draining plate 4 to be removed from the lower side.
It's hidden.

Furthermore, since the inclined piece 42 of the secondary draining plate 4 is provided facing the rear wall 33 of the eaves gutter 3, dirt on the secondary draining plate 4 itself is not noticeable.

That is, it is possible to prevent rainwater from hitting and staining the visually visible portion of the decorative board 8, and the beauty of the eaves can be maintained.

Next, the eaves structure of the second embodiment will be explained based on FIG.

In describing the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals in the drawings and their explanation will be omitted. Further, regarding the operations, explanations of operations similar to those of the first embodiment will be omitted.

In this embodiment, the secondary draining board 4a is formed in a shape that also serves as a part of the decorative board, and the decorative board 8a is extended from the tip of the shedding board 5.
A horizontal plate portion 41a extending almost horizontally toward
It is composed of a vertical plate portion 42a extending substantially perpendicularly along the direction a, and an inclined plate portion 43a protruding diagonally downward from the surface of the decorative board 8a. The eaves gutter 3 is attached such that the inclined plate portion 43a of the secondary draining plate 4a faces the rear wall 33 of the eaves gutter 3 with a gap 44a in between.

Therefore, rainwater splashed up in the eaves gutter 3 or rainwater blown up by the wind hits the horizontal plate portion 41a or the vertical plate portion 42a of the secondary draining plate 4a, and the rainwater splashed up in the eaves gutter 3 hits the horizontal plate portion 41a or the vertical plate portion 42a of the secondary draining plate 4a, and the inclined plate portion 43 of the secondary draining plate 4a
a and flows down from the gap 44a between the rear wall 33 of the eave gutter 3 and the inclined plate part 43a.

That is, the inclined plate portion 43 of the decorative board 8 that is treated as a secondary drainer 4a
The lower part of the secondary draining plate 4a is prevented from getting dirty due to rain water, and even if the part of the secondary draining plate 4a above the inclined plate part 43a gets dirty by rain water, the inclined plate part 43a prevents the lower part from getting dirty. covered up from

In addition, in the eaves structure of this embodiment, before fixing the support 2 and the eaves gutter 3 to the fascia handle 7, the secondary draining board 4a is attached to the decorative board 8 in advance.
It needs to be fixed.

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.

Further, in the embodiment, a hanging type support is shown, but a receiver type support may also be used.

Further, the fixing position of the secondary drainer is not limited to the embodiment, and for example, it may be fixed to the eaves surface above the mounting rod of the support. However, in order to make the dirt on the eaves surface and the dirt on the secondary drainage board itself less noticeable, it is desirable to set it above the bottom wall of the eaves gutter.

(Effects of the Invention) As explained above, in the eaves structure of the present invention, since the secondary draining plate is provided on the eaves surface, the portion of the eaves surface below the secondary draining plate is It can prevent dirt from being contaminated by dust mixed with rainwater.

Furthermore, even if the portion above the secondary draining plate becomes dirty due to rainwater, it can be covered from below by the secondary draining plate. Therefore, it is possible to prevent rainwater from hitting and staining the externally visible eaves part, and it is possible to maintain the beauty of the eaves.

In addition, in the construction method of the eaves structure of the present invention, an eaves structure having the above-mentioned effects can be obtained by simply adding a secondary draining plate to the eaves surface afterward in addition to the conventional eaves structure.
