Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gutter device that is attached to the eaves of a house or the like.

[Conventional technology and its issues]

As a conventional roof gutter, as shown in Fig. 6, the outer periphery of the gutter body 1, which is constructed in the form of a channel with an iron plate, is extended from the pillars 2 of building structural members through support members 3 and extension members 4 from the rafters. It is known that the housing is supported by a U-shaped support fitting 5 attached to the edge of the eaves.

By the way, in order to construct such a gutter,
As shown in the figure, pillar P, gassho G, beam B and main building M
At the eaves of the building, which is made up of parts such as the roof, after assembling the gutter support members, etc., it is necessary to stretch water strings and position them in the vertical direction. The problem was that work efficiency was low because the work of roofing and installing gutters was carried out by different workers depending on the type of industry.

In particular, as a gutter function, it is necessary to reliably guide collected rainwater to the drainage section, and for this purpose, the length of the gutter must be
It is said that it is desirable to create a slope of approximately 10 mm per 2000 mm, or approximately 0.5%, but with conventional structures, it is difficult to accurately manage such slopes when constructing gutters. This is one of the causes of deteriorating work efficiency.

In addition, in some cases, in order to unify the appearance of the gutter and satisfy the above-mentioned slope requirements,
As shown in the figure, it is necessary to cut the iron plate with a tapered mold according to the amount of correction of the slope and process the gutter body 1 on-site.

On the other hand, in the case of the illustrated gutter device, in order to hide irregularities in the slope of the gutter body 1 and improve the appearance,
Although an exterior gutter 6 as shown in FIG. 6 or FIG. 9 is provided, if the gutter body 1 can be constructed in an orderly manner, it is not necessarily necessary to prepare such exterior members; It is possible to reduce the weight, simplify the structure, and reduce the cost of the gutter device.

Furthermore, there is a gutter hanging fitting for folded roofs shown in Utility Model Application No. 62-137938. This gutter hanging fixture is a fixture that is attached to the eaves gutter via bolts and nuts, and is suitable for obtaining the vertical position and desired slope of the gutter body by adjusting the nuts. but,
Since the gutter hanging fittings were attached to the upper part of the gutter body, there were problems in terms of air circulation within the gutter body and corrosion of the gutter body due to this. Furthermore, fallen leaves and debris tend to accumulate inside the gutter body, and when the standard storage capacity of the gutter body is exceeded due to heavy rain, etc., it is necessary to install a drainage outlet in the gutter body in advance to prevent rainwater from exceeding the weight. The point was hot.

In addition to the above, the rain gutter structure described in Utility Model Application Publication No. 61-49828 is also known, but this rain gutter structure also has the same problems as the gutter hanging fittings mentioned above, and the cross section is approximately U.
The problem is that because the letter-shaped gutter body is fitted with the hanging fitting at the upper edge of its side surface, the gravity of the gutter body is concentrated at this fitting point, making it unsuitable for large-scale gutter equipment. It was hot too.

The present invention has been made with attention to the current situation, and an object of the present invention is to provide a gutter device that can easily impart an appropriate slope to the gutter body, has excellent installation workability and appearance, and is also suitable for large-sized gutter. It is an object.

[Means to solve the problem]

A gutter device according to the present invention is a gutter device in which a gutter body having a substantially U-shaped cross-sectional shape is attached to the eaves of a building by a hanging metal fitting made of a fixing member having a guide portion, and the hanging metal fitting includes: Above the side of the gutter body, and
It is characterized in that an auxiliary gutter member for guiding rainwater inward of the gutter body is attached so as to be positioned substantially parallel to the gutter body.

[Effect]

The above-mentioned gutter device according to the present invention includes an auxiliary gutter member for guiding rainwater inward of the gutter body, which is positioned above the side surface of the gutter body and approximately parallel to the gutter body, on the hanging fitting. By installing this, the auxiliary gutter member can be attached to the gutter body with a predetermined gap between them, which improves air circulation within the gutter body, making it easier for water that collects at the bottom of the gutter body to dry quickly. Therefore, it has the effect of preventing corrosion of the gutter body.

Further, if the gap is made large, it is possible to easily clean fallen leaves inside the gutter body from the outside.

Furthermore, if the rainwater flowing inside the gutter body exceeds the standard storage capacity due to heavy rain, etc., the rainwater will overflow from the top of the gutter body, so conventional methods of preventing rainwater from exceeding the weight of the water, which were installed at required points on the gutter body, This eliminates the need for troublesome work such as providing a drainage outlet, and makes it easier to partially repair the gutter device.

Moreover, it is easy to vary the color of the gutter body and auxiliary gutter members, which has an excellent effect in terms of design. It is also possible to provide gutter devices that are also suitable for buildings.

In addition, projecting stripes are provided at approximately midpoints of both side surfaces of the gutter body, and these projecting stripes are formed on shoulders formed on both sides of the movable member. By holding the gutter in the hanging fitting so as to engage with it, it is possible to ensure sufficient torsional rigidity and bending rigidity of the gutter body.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each embodiment, substantially the same parts are given the same reference numerals, and description thereof will be omitted.

In FIGS. 1A and 1B, reference numeral 10 indicates a variable hanging fitting, and 20 indicates a gutter body supported by this hanging fitting 10.

The hanging fitting 10 includes a fixing member 11 fixed to the tip of the eave of a metal rafter 9 attached to the main roof (not shown) in the direction of the eaves, and is movable in the vertical direction with respect to the fixing member 11. It is comprised of a movable member 12 that holds the gutter body 20, an adjustment connecting means 13 that connects both members 11 and 12 so that they can move relative to each other, and the like. Both the fixed member 11 and the movable member 12 are made of band-shaped metal plates with a width of about several tens of millimeters.

The fixing member 11 has a first guide portion 11b extending vertically downward from the end of a flange portion 11a that is fastened to the tip of the rafter 9 via one or more sets of bolts/nuts 14. A second guide part 11d is provided in parallel to the first guide part 11b at the tip of a beam part 11c supported horizontally from the upper part of the first guide part 11b.
In this case, the first guide part 11b, the beam part 1
1c and the second guide portion 11d are connected to each other by welding.

On the other hand, the movable member 12 has an inverted U-shaped main body part 12a that is loosely fitted from below between the mutually parallel guide parts 11b and 11d of the fixed member 11, and a main body part 12a that is stretched outward from the lower ends on both sides thereof. The protruding shoulder portions 12b are integrally formed by press working, and the gutter body 20 is attached to the outer surfaces of the shoulder portions 12b via fasteners 15 such as screws or rivets.

Further, the adjusting and connecting means 13 includes an adjusting screw 13a that connects the fixed member 11 and the movable member 12, and this adjusting screw 13a adjusts the vertical position between the fixed member 11 and the movable member 12 according to the amount of rotation thereof. It is vertically installed between both members so that the distance in the direction changes. That is, in this case, a bolt-shaped adjustment screw 13a having a predetermined length is inserted upward from below into the center of the movable member body 12a, and is then fixed to the body 12a with a fixing nut 13b. Further, the tip of the adjusting screw 13a is passed through a through hole 11e drilled in the center of the fixing member beam portion 11c, and then an adjusting nut 13c is screwed thereon.

The adjusting screw 13a is freely movable in the axial direction with respect to the through hole 11e, so that the adjusting nut 13c
By screwing into the adjustment screw 13a, the movable member 12 moves upward together with the adjustment screw 13a, and the vertical distance between it and the fixed member 11 is reduced. Conversely, by loosening the adjustment nut 13c, the movable member 12 is adjusted. It descends together with the screw 13c due to gravity, and the vertical distance between it and the fixing member 11 increases. still,
The adjustment screw 13a may be welded to the movable member body 12a.

Next, the gutter body 20 is a long material formed by pressing a metal plate material such as a steel plate, and the bottom part 20a
It has a substantially U-shaped cross-sectional shape with side surfaces 20b rising from both edges. As described above, the shoulder portion 12b of the movable member 12 is fixed to the inside of the side surface portion 20b, and a protruding portion 20c that protrudes inwardly is provided at a portion slightly above the fixed portion. The upper end thereof is formed as a folded part 20d which is curled inwardly, and these protrusions 20c and folded part 20d ensure torsional rigidity and bending rigidity of the gutter body 20. The appearance has been improved.

When this gutter main body 20 is supported at the eaves with variable hanging fittings 10 at multiple appropriate locations in the longitudinal direction as shown in FIG.
Since the position can be adjusted in the vertical direction by turning the gutter body 20, the overall position and slope of the gutter body 20 can be adjusted reliably and easily. The adjustment width at this time is the amount of upward movement when the movable member shoulder portion 12b is placed at the lower end of the fixed member guide portions 11b and 11d.
However, the amount of downward movement depends on the length of the adjustment screw 13a, so by using a sufficiently long adjustment screw 13a, the adjustment width in the vertical direction can be made insufficient. It is possible to secure it without any problems.

In addition, for rainwater drainage holes and side eaves parts (not shown), the gutter body 20 does not need to be supported by the variable hanging fittings 10, and these parts are attached with fixed hanging fittings as in the past, and they can be attached to other parts. The slope may be adjusted using a variable hanging fitting 10.

By the way, in this embodiment, the depth of the gutter body 20 is suppressed to about half of the total height of the hanging fitting 10, so that the second guide of the fixing member exposed above the outer side surface portion 20b of the gutter body 20 is Two upper and lower rows of auxiliary gutter members 30 are provided on the side surface of the portion 11d so as to be located substantially parallel to the gutter body 20.

As shown in FIG. 2A, the auxiliary gutter member 30 has a water receiving portion 30b that expands outward and upward from a flange portion 30a that is fixed to the guide portion 11d via the fastener 15. is formed, and rigidity is ensured by a folded portion 30c formed by curling the upper edge of the water receiving portion 30b.

FIG. 2B shows another example of the auxiliary gutter member 30.
This involves molding bulging portions 30d at predetermined intervals along the longitudinal direction of the water receiving portion 30b, and forming the bulging portions 30d
This changes the appearance and ensures rigidity.

In this way, the outer surface of the gutter device is connected to the gutter body 20.
By adopting a multi-stage structure in which the auxiliary gutter members 30 are arranged on top of the gutter, it is possible to prevent rainwater from dripping on the side surfaces of the gutter and improve water catching performance. That is, if the side surface of the gutter device is covered over its entire height with the side surface portion 20b of the gutter body 20, the side surface portion 20b
Rainwater that has landed on the rainwater can only drip downward, but by providing the auxiliary gutter members 30, the rainwater tends to adhere to the side surfaces inward through the gap between the auxiliary gutter members 30 or the gutter body 20. This is because rainwater can be introduced.

3 and 4 show other examples of shapes of such auxiliary gutter members. FIG. 3 shows that auxiliary gutter members 30 are provided on both sides of the fixing member 11 of the hanging fitting, that is, on both the first guide part 11b and the second guide part 11d, and in three rows up and down, so that rainwater falling onto the gutter side can be removed. This further improves the interpolation performance of . In this case, from the bottom 20a of the gutter body 20 to the side surface 20
The connecting portion to b has a curved surface shape, which, together with the provision of three rows of auxiliary gutter members 30, provides a stronger change in appearance. Also, Figure 4 shows
Among the two rows of auxiliary gutter members 30, the higher the one located, the wider the sideward expansion width is, so that even if a large amount of rainwater falls from the eaves of a roof, for example, it will be reliably directed to the gutter body 20. This is an example of improving the collection performance so that it can be taken in.

FIG. 5 shows another embodiment of the gutter device according to the invention. In the figure, 31 and 32 are a gassho and a pillar made of H-type steel, 9 is a rafter attached to the gassho 31 via a purlin member 35 made of C-type channel material, and 33 is a wall surface also attached to the column 32. It is a member. In this embodiment, as shown, the gutter device located at the tip of the rafter 9 is provided as close as possible to the wall member 33, thereby saving space. In this case, a large auxiliary gutter member 30'a is provided to block the front of the eaves of the rafter 9 so that rainwater falling from the roof surface to the eaves can be reliably repaired as shown by the arrow, and this auxiliary gutter member 30'a In order to prevent the water flow that has collided with the gutter member 30'a and reversed from flowing downward from between the gutter body 20 and the wall member 33, the area under the eaves from the upper end of the gutter body 20 is also covered on the side of the wall member 33. A large auxiliary gutter member 30'b is provided.

In this embodiment, the protrusions 20c protruding from both side surfaces of the gutter body 20 are engaged with both shoulders 12b of the movable member 12 using the elasticity of the gutter body 20 itself, thereby suspending the gutter body 20. It is held in place by a metal fitting, which further simplifies the construction work of the gutter device.

〔Effect of the invention〕

As explained above, in the gutter device according to the present invention, the hanging metal fittings are provided above the side surface of the gutter body, and
By installing the auxiliary gutter member that guides rainwater inward to the gutter body so as to be positioned approximately parallel to the gutter body, the auxiliary gutter member can be attached to the gutter body with a predetermined gap. Because it is possible to
Air circulation within the gutter body improves, and water that collects at the bottom of the gutter body dries quickly, which helps prevent corrosion of the gutter body.

Further, if the gap is made large, it is possible to easily clean fallen leaves inside the gutter body from the outside.

Furthermore, if the rainwater flowing inside the gutter body exceeds the standard storage capacity due to heavy rain, etc., the rainwater will overflow from the top of the gutter body, so conventional methods of preventing rainwater from exceeding the weight of the water, which were installed at required points on the gutter body, This eliminates the need for troublesome work such as providing a drainage outlet, and makes it easier to partially repair the gutter device.

In addition, it is easy to vary the color of the gutter body and auxiliary gutter members, which has an excellent design effect. It is also possible to provide gutter devices that are also suitable for buildings.

In addition, projecting stripes are provided at approximately the middle of both side surfaces of the gutter body, and these projecting stripes are used as shoulders formed on both sides of the movable member. By holding the gutter in the hanging fitting in such a manner as to engage with it, it has many effects such as being able to ensure sufficient torsional rigidity and bending rigidity of the gutter body.
