Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a system in which rain gutters are placed below the gap between the roof and the eaves, making the appearance of the roof significantly more attractive, and also extremely easy to construct. This relates to the structure of the eaves of houses that has been made possible.

<Prior art> Generally, rain gutters are installed at the eaves of the roofs of buildings, and the rain gutters described above are held in place by rain gutter holders placed at appropriate intervals on the rafters or fascia of the eaves. There is.

In addition, there have been conventional methods for storing rain gutters inside the roof near the eaves to improve the appearance of the roof.
-There is a roof configuration described in Publication No. 160820.

The conventional roof structure described above consists of fixing structural members to pillars or external walls, covering the top of the rain gutter with wire mesh, and then attaching flat roof plates from the side edges of the rain gutter to form the eaves. Alternatively, a perforated part consisting of a large number of holes is provided at a position slightly set back from the leading edge of the eaves on a flat roof surface, and an eaves gutter is arranged below the perforated part.

<Problems to be Solved by the Invention> However, in the conventional general eaves structure described above, accidents often occur in which rain gutters are damaged when snow accumulated on the roof slides down. In addition, in eaves structures where rain gutters are installed inside the roof to improve appearance, a net is provided on the top of the rain gutters.
When accumulated snow slides down, the net creates great resistance, and once it gets stuck in the rain gutter, it stays there for a while, and when it reaches its limit, it falls all at once.
Therefore, a large amount of snow falls together from the eaves to the ground, posing a risk of injury to people walking under the eaves. Moreover, since conventional roof shingles do not have flat horizontal steps, the water-conducting part that allows rainwater to flow into the rain gutter is exposed on the part of the roof near the eaves, spoiling the appearance of the roof. Become. Furthermore, in the rain gutter described in Utility Model Application Publication No. 59-158628,
The top protection plate is attached via fixing tools,
Since it is not installed in the rain gutter, the protective plate using the fixing tool and the rain gutter using the rain gutter metal fittings must be installed separately, which not only reduces work efficiency but also increases the number of parts, creating an economic burden. ing.

Therefore, there is a need for a roof eave structure in which the rain gutter is installed inside the roof, the water passage part is extremely inconspicuous, does not spoil the appearance, and is extremely simple and easy to work with. .

<Means for Solving the Problems> The present invention was proposed in order to solve the above-mentioned conventional drawbacks and to meet the conventional demands. A roof sheet material having a second bent portion bent upward at the rear end thereof, the second bent portion of the roof sheet material located on the lower side and the first bent portion of the roof sheet material located on the upper side. By engaging with the roof part, the roof part is horizontally roofed, and the eaves part is formed with a distance from the roof part, respectively,
A rain gutter whose top surface is open is arranged below the gap between the roof part and the eaves, and the rain gutter is provided with a water-permeable lid body having a plate-like upper surface part, and the water-permeable lid body has an upper surface part. is located substantially on the same plane as the sloped lower end of the roof and the sloped upper end of the eave part, and the stepped portion formed by the first bent part of the roof board located at the sloped lower end of the roof has the above-mentioned water permeability. It is characterized by facing the top surface of the lid.

<Example> Below, the present invention will be explained with reference to the embodiments shown in the drawings. 1 is a house, 2 is a pillar of the house 1, 3 is a roof part, and 4 is arranged at a distance from the roof part. This is the eaves section.

The house 1 has a roof part 3 and an eaves part 4 formed on the sloped downward side of the roof part 3. Thatch and compose.

The above-mentioned roof board material 8 is a horizontally long board material having a first bent part 82 bent downward at the front end of a plate part 81 and a second bent part 83 bent upward at the rear end. Then, the first bent part 82 of the roof plate part 8 placed on the upper side is engaged with the second bent part 83 of the roof plate material 8 placed on the lower side to perform horizontal roofing. Therefore, when the roof board materials 8 are horizontally roofed, a stepped portion corresponding to the height of the first bent portion 82 of each roof board material 8 is formed in the horizontal direction.

A bent support 10 is installed on the outdoor side of the pillar 2, and is provided with a bent upper end 9 that is bent into an arc shape near the upper end. An upper horizontal member 11 is provided between the bent support 10 and the pillar 2.

A deformed purlin 13 is installed on the upper surface of the above-mentioned upper cross member 11 to support the bent upper end portion 9 of the bent support column 10.

The above-mentioned eaves portion 4 is formed into a curved surface by horizontally covering the roof plate material 8 along the bent support columns 10 in the same manner as the roof portion 3.

The rain gutter 14 provided below the gap between the roof part 3 and the eaves part 4 is provided with flat step parts 16 and 17 at both ends of a horizontally long groove 15, and extends almost perpendicularly from the step part 16 on the indoor side. Outer waterproofing 19 is extended from the raised inner waterproofing 18 from the step 17 on the outdoor side, and furthermore, an inner inclined flange 20 is connected to the inner waterproofing 18, and an outer inclined flange 21 is connected to the outer waterproofing 19. With a configuration in which the upper surface extending outward is open, both inclined brim 20, 21
is bent to have substantially the same slope as the roof portion 3.

The rain gutter 14 as described above is placed on the upper surface of the upper horizontal member 11 in the direction of the eaves of the house 1, and the inner inclined brim 21 is placed on the rafter 7.
and the main house 6, and the outer inclined collar 21 is sandwiched between the bending tip 9 of the bending support 10 and the deformable main house 13.

A water-permeable lid 22 is installed on the top of the rain gutter 14 so as to close the open top surface.

The above-mentioned lid body 22 has a plate-shaped upper surface part 23 having an inclination angle that is substantially the same as the slope of the roof part 3, an inwardly inclined wall 24 extending downward on both sides of this upper surface part 23, and an outwardly inclined wall 24. The lower edges of both inclined walls 24 and 25 are provided with flanges 26 and 27 corresponding to the steps 16 and 17 of the rain gutter 14 described above.

A large number of holes 28 are formed in the upper surface 23 of the water-permeable lid 22, and in this embodiment, horizontally elongated holes are formed as shown in FIG.

Rainwater and melted snow flow into the rain gutter 14 through the holes 28 in the upper surface portion 23.

As shown in the sectional view of FIG. 4, the inner circumferential edge of the hole 28 is formed with a downward arcuate bent edge 28' so that even if a force is applied from above, only a small resistance will be produced. Sometimes the snow slides down very smoothly.

In the above, upward refers to the direction from the ridge toward the eaves, and force refers to the frictional force that occurs when rainwater or snow falls or slides down on the roof surface.

The above-mentioned lid body 22 can be made by punching a metal plate or by molding a synthetic resin.

In addition, in the embodiment shown in the drawings, the inclined wall 24 of the lid body 22,
A drain hole 29 is provided at the lower end of 25, and both inclined walls 2
4, 25 is introduced into the rain gutter 14, but this is because both inclined walls 24, 2
5 may be made into a slatted shape, or the roof plate material 8 may be extended to the upper surface of the upper surface portion 23. In short, it is sufficient to form a structure that allows all of the water to be introduced into the rain gutter 14 and to allow the rain to drain well.

Furthermore, by constructing the water-permeable lid body 22 from a plurality of members, some of which are removable from the rain gutter 14, the rain gutter 14 can be opened and closed, making maintenance of the interior extremely easy. It's okay.

As described above, the rain gutter 14 is provided between the roof part 3 and the eaves part 4, and the water permeable lid 22 is provided in the rain gutter 14.
If provided, the plate-shaped upper surface portion 23 of the water-permeable lid 22
is located substantially on the same plane as the sloped lower end of the roof part 3 and the sloped upper end of the eaves part 4, and the first bent part 82 of the roof board material 8 located at the sloped lower end of the roof part 3 is located on the upper surface. Facing part 23. Therefore,
Since it appears as a stepped portion in the vertical direction, when viewed from the ground, the stepped portion formed by the first bent portion 82 of each roof sheet material 8 of the eave edge portion 4 is continuous.

FIGS. 5 and 6 show another embodiment of the present invention, in which the lid body 22 of the previous embodiment is replaced with
Armor lid 30 as a plate-shaped upper surface part of a water-permeable lid body
is installed on the upper surface of the rain gutter 31 in a closed manner.

The armor lid 30 has both steps 32 and 3 of the rain gutter 31.
3, continuous support leg frames 36 having a trapezoidal cross-sectional shape are arranged at appropriate intervals, and an armor plate 37 is constructed between the support leg frames 36 and 36. be. The armor plate 37 consists of a long flat plate part 38 at the center, a slope part 39 with one side extending downward with a gentle slope, and a bent part 40 having the other side bent short in the same direction as the slope part 39. Armor plate 3
7 to the support leg frame 36, the lower armor plate 3 is installed under the bent portion 40 of the upper armor plate 37.
The slope portions 39 of No. 7 are arranged to form a space 41.

Therefore, water flowing down the roof flows into the rain gutter 31 through this space 41. The armor lid 30 formed as described above is secured to the stepped portions 32 and 33 of the rain gutter 31 by the foot portions 34 and 35 of the support leg frame 36.

The rain gutter 31 used in this embodiment is almost the same as that in the previous embodiment, but the positional relationship of each part in the cross-sectional view is slightly different.

That is, the step portions 32 and 33 of the rain gutter 31 are formed parallel to the slope of the roof portion 3, and the waterproof hangers 42 and 43 on both sides are shortened. Such a rain gutter 31 is placed on the horizontal members 44 in the direction of the eaves in the same manner as described above, and the sloped flanges 4 at both ends are
5 and 46 are clamped and fixed between the rafters 7 and the main buildings 6 and 13. A rain cover 30 is attached to the upper part of the rain gutter 31, and foot parts 34 and 35 are locked to the step parts 32 and 33.

According to the eaves structure configured in this way, almost no unevenness is formed from the roof part 3 to the eaves part 4, and since the bent part 40 of each armor cover 30 and the slope part 39 are continuous, no force is applied from above. Even if the resistance is applied, the resistance is only small, so that the snow slides down better than in the above-mentioned embodiments. Moreover, since the roof part 3 and the eaves part 4' are reliably separated by the rain gutter 31, rain can be cleared easily.

In the embodiment shown in FIG. 5, the eaves section 4' is formed by extending the slope of the roof section 3 in a straight line. good. Further, the connecting and fixing means in the present invention can be appropriately selected from nailing, adhesive, welding, etc.

<Effects of the Invention> In summary, according to the present invention, a roof sheet material having a first bent part bent downward at the front end and a second bent part bent upward at the rear end, By engaging the second bent part of the roof sheet material located on the lower side and the first bent part of the roof sheet material located on the upper side, horizontal roofing is performed to create a roof part and an interval with respect to the roof part. a rain gutter whose top surface is open is disposed below the gap between the roof portion and the eaves portion, and a water-permeable lid body having a plate-shaped upper surface portion is provided in the rain gutter; The upper surface of the water-permeable lid body is located substantially on the same plane as the sloped lower end of the roof and the sloped upper end of the eaves, and the first bent part of the roof plate material is located at the sloped lower end of the roof. Since the stepped portion faces the upper surface of the water-permeable lid, the slope of the roof can be gradually reduced without snow accumulated on the roof accumulating or accumulating on the upper surface of the water-permeable lid, especially in areas with heavy snowfall. You can slide down smoothly.

Therefore, there is no danger of the snow that accumulates in the rain gutter being unable to withstand the weight of the conventional rain gutter and falling in clumps, injuring pedestrians near the eaves, and the rain gutter will not be damaged or bent. In addition, rainwater can reliably flow into the rain gutter.

In addition, the rain gutter is installed below the gap between the roof and the eaves, and the upper surface of the water-permeable lid is located on the same plane as the lower end of the roof and the upper end of the eaves. Therefore, when viewed from the ground, it has a planar shape, and the step part formed by the first bending part of the roof board material at the eaves and the step part formed by the first bend part of each roof board material at the roof part are continuous. Even if there is a water-permeable lid in between, it is not noticeable, so there is no discomfort in the appearance, and it has an extremely good-looking and luxurious feel. Further, a roof part and an eave part are formed with a space provided between the roof part and the eave part, and a rain gutter whose top surface is open is placed below the gap between the roof part and the eave part, and this rain gutter is equipped with a board. Since the water-permeable lid body has a shaped upper surface, there is no need to hold the lid body with separate metal fittings if the rain gutter is supported, which not only reduces the number of parts but also makes the construction work extremely simple. , can be constructed inexpensively. Moreover, if fallen leaves, dust, dirt, etc. accumulate in the rain gutter, they can be removed by simply removing the lid from the rain gutter, so the rain gutter can withstand long-term use. In addition, since the top surface of the lid is plate-shaped, by molding it with the same material as the roof and eaves, it creates a sense of unity with the roof and eaves, enhancing the value of the roof and making it more practical. becomes.
