Description

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

(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 remote location.

In addition, in recent years, as the eaves have become smaller,
The mounting position of eaves gutters has come close to being treated as a fascia.On the other hand, houses with whitish walls have become popular, and as a result, people are becoming more strict about dirt.

(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, a drainage board is installed downward from the tip of the roof board, and the rainwater that falls from the tip of the roof board flows through the drainage board and 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 gutter construction and the work efficiency deteriorates.

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 that blows on the fascia board blows up the gap between the drainer and the eaves gutter, so that when it rains, the rainwater that falls from the tip of the drainer board is blown up by the wind. There was also the problem of hitting the fascia boards and walls of houses.

The present invention has focused on the above-mentioned conventional problems, and aims to provide an eaves structure that can prevent the side surfaces of the eaves from being soiled by rainwater splashed up in the eaves gutters or blown up by the wind. It is said that

(Means for Solving the Problems) In order to achieve the above object, the eaves structure of the present invention is provided with a draining board facing downward at the tip of the roof board, and on the sides of the eaves wall, fascia board, etc. Supports are fixed at predetermined intervals,
An eaves structure in which an eave gutter is supported by the support,
The support is fixed to the eaves through a rail member, and the rail member has a drain portion projecting from the bottom wall of the eaves gutter.

(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.
In addition, when rainwater splashes up at the bottom of the eaves gutter and hits the side of the eaves, the rainwater that hits the side of the eaves is guided by the drainage part of the rail member and flows downward.

Therefore, rainwater does not run down the portion of the side surface of the eaves below the draining portion, so that it is prevented from becoming dirty with dust mixed with the rainwater.

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

First, the configuration of the embodiment will be explained.

FIG. 1 is a longitudinal sectional view showing the structure of the eaves of this embodiment, where ■ is a draining board, 2 is a support, 3 is an eaves gutter, and 4 is a rail member.

The draining board 1 is bent and formed into a dogleg shape in cross section, and the upper piece is fixed to the upper surface of the shedding board 5, and the lower piece is attached to the shedding board 5.
It is provided so as to extend downward from the tip. Incidentally, the draining plate 1 may be formed of a metal plate or a synthetic resin.

The support 2 is a fascia 7 provided at the tip of the rafter 6.
are fixed at predetermined intervals along the side surface.

The support 2 is composed of a mounting rod 21 and a support rod 22, and the mounting rod 21 and the support rod 22 are formed by bending a long metal plate. One end of the mounting rod 2I is bifurcated into upper and lower halves, with the upward piece 211 being fixed to the fascia plate 7 via the rail member 4, and the downward piece 212 directly attached to the fascia plate 7. Fixed with screws. and the support rod 22
is joined to the front end of the mounting rod 21 approximately at the center by welding or the like. Further, at both ends of the support rod 22, bent pieces 221 and 222 of cross-sectional ear pieces are respectively formed, and these ear pieces are elastically deformable at positions opposite the pieces 211 and 222. The stopper piece 223 is removed by the handling spring.
．． 224 is formed.

The rail member 4 is horizontally fixed to the fascia plate 7 at a position above the lower end of the draining plate l.

Moreover, this rail member 4 is formed in a groove shape that can be fitted with the upwardly facing piece 211 of the mounting rod 21, and has a primary drain section 41 at the upper end and a secondary drain section 42 at the lower end thereof. It is installed protrudingly.

Note that the material of this rail member 4 may be a synthetic resin or a metal plate. Furthermore, the molding methods include pengu, drawing, extrusion, etc. Furthermore, when fixing the rail member 4 to the decorative board 8, it is possible to use adhesive, welding, rivets, or the like.

The eaves gutter 3 is extruded from a synthetic resin such as hard vinyl chloride resin, and has walls 32 and 33 erected on both sides of a flat bottom wall 31 that are slightly inclined outward. . Additionally, hollow ears 34.35 are formed at the upper ends of these side walls 32.33, respectively, and reinforcing ribs 36.3 are formed on the inner surfaces of the corners of the bottom wall 31 and side walls 32.33, respectively.
7 is formed.

The eaves gutter 3 is supported in a suspended state by the support 2 and attached along one edge of the eaves. That is, both ear parts 34.35 and the ear receivers of the support 2 are on one side 221.22.
2, and the removal stopper pieces 223 and 224
It is prevented from falling off. In addition, the ears 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.

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 passes through the draining board 1 and falls into the eaves gutter 3.

However, when there is a wind, the rainwater that falls from the tip of the eaves tile 10 is blown away by the wind and becomes the eaves 111! ! 3. If the eaves tile does not fall and hits the fascia board 7, or if there is a lot of rainfall, the eave tile lO
Rainwater flowing down from the tip of the eaves gutter 3 often bounces up at the bottom and hits the fascia board 7. In these cases, rainwater that hits the fascia plate 7 is guided by the primary drainage part 41 of the rail member 4 and flows down from between the rear wall 33 of the eaves gutter 3 and the fascia plate 7.

Here, even if rainwater enters the inside of the rail member 4 along the mounting rod 21 of the support 2, the rainwater will be guided to the secondary drainage part 42 and will be directed to the rear wall 33 of the eaves gutter 3 and the fascia plate. It flows down from between 7 and 7. In addition, the secondary draining section 42
It is desirable to provide a slight gap between the front end surface of the mounting rod 21 and the rear surface of the mounting rod 21.

Therefore, rainwater does not run down the portion of the fascia plate 7 below the draining portion 41, so that it is prevented from becoming dirty with dust or the like mixed in the rainwater.

That is, it is possible to prevent the visually visible portion of the fascia board 7 from being contaminated by rainwater, and the beauty of the eaves can be maintained.

In addition, the support 2 of this embodiment structure can be fixed to the fascia plate 7 with one touch by fitting the upward piece 211 of the mounting rod 21 into the rail member 4, so that the support 2 can be fixed to the fascia plate 7. The draining board■ will not become an obstacle. Therefore, the fixing position of the support 2 can be set at a higher position than in the case of the conventional structure.

It is also possible to bring the draining board 1 and the eaves gutter 3 closer together to shorten the distance over which rainwater falls. By doing so, it is also possible to reduce the height at which rainwater flowing down from the tip of the eaves tile lO splashes up within the eaves gutter 3.

In addition, since the rail member 4 provides horizontality, the support 2 can be fixed to the fascia plate 7 without using a water system. Incidentally, when it is desired to give the eaves gutter 3 a water slope, the same effect can be obtained by giving the rail member 4 a slope.

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 embodiment, an example is shown in which the support is made of a metal plate, but this support may be made of synthetic resin. In that case, the mounting rod and the support rod may be integrally molded.

In addition, although a hanging type support is shown in the embodiment, a support type support may also be used.Furthermore, as a means of fixing the support to the fascia plate, it is possible to fit the support to the rail member and fix it with screws. Although it is used in combination with the rail member, it may be fixed simply by fitting it to the rail member. However, in that case, it is necessary to ensure a strong fit.

In addition, in the embodiment, the drainage part of the rail member was formed to guide rainwater between the rear wall of the eaves gutter and the fascia plate, but it protrudes from the upper end of the rear wall to a position forward of the upper end of the rear wall in order to guide rainwater into the eaves gutter. You may have them set up.

(Effects of the Invention) As explained above, in the eaves structure of the present invention, the rail member is provided with a draining portion, so that the portion of the side surface of the eaves below the draining portion is mixed with rainwater. This can prevent dirt from being contaminated by dust, etc. 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.
