Description

[Technical field]

[0001] The present invention relates to a rain gutter that also functions as a snow guard and a roof structure using the same. [Background technology]

[0002] In order to prevent rain from dripping from the eaves of a building's roof, a semi-cylindrical rain gutter that opens upward is usually installed separately from the roof. In areas with a lot of snowfall in winter, snow guards are also installed to prevent snow from falling from the roof. In winter, conventional gutters that are installed separately on the roof (hereinafter simply referred to as "conventional gutters") are prone to freezing, and even if snow guards can protect the gutters from snow accumulation to some extent, they are prone to damage due to the weight of frozen rainwater. In response to this, a technique for preventing the rain gutters from freezing has been proposed (see, for example, Patent Document 1). According to Patent Document 1, a gutter cover is installed from the tip of the eaves of the roof to the outer edge of the gutter. This prevents snow from entering the gutter, and allows meltwater from the snow to flow down the underside of the gutter cover and drip into the gutter. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-189441 [Patent Document 2] JP 2017-206831 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the anti-freezing structure for gutters described in Patent Document 1, the gutters are installed on the outside of the roof, so if the gutters fill with rainwater and freeze, their weight will be large and the load on the gutters will be great.

[0005] In order to solve the above problems, the inventor of the present application proposed a rain gutter that also functions as a snow guard, without using a conventional rain gutter (see Patent Document 2). This snow gutter that also functions as a snow guard is placed and fixed on the top surface of the eaves of the roof without using the conventional rain gutter, which promotes snow melting and has excellent strength as a rain gutter. The present invention aims to provide a snow-guard / rain gutter that is a further development of the snow-guard / rain gutter described in Patent Document 2 and that has sufficient strength to withstand large amounts of snow, promotes snow melting, and exhibits excellent functionality as a rain gutter, as well as a roof structure using the same. [Means for solving the problem]

[0006] The present invention is as follows. 1. A gutter that also doubles as a snow guard is placed and fixed to the eaves of a roof that slopes downward toward the eaves side. A flat base plate to be fixed onto the roof; An inclined plate connected to one end of the base plate on the eaves side and inclined upward toward the eaves side; A standing plate connected to the inclined plate and extending downward from the upper end of the inclined plate and standing on the roof; A bottom plate connected to the lower end of the upright plate and fixed onto the roof; A rain gutter that also functions as a snow guard is provided.

[0007] 2. The snow guard / rain gutter is made up of a main body member and a support member joined to the main body member. The main body member is integrally formed of a flat base plate, an inclined plate connected to one end of the base plate on the eaves side and inclined upward toward the eaves side, and a first standing plate connected to the inclined plate, extending downward from the upper end of the inclined plate and standing on the roof, The support member is integrally formed with a second standing plate and a bottom plate connected to the lower end of the second standing plate and fixed to the upper surface of the roof, The snow guard / gutter described in 1., wherein the first standing plate and the second standing plate are surface-joined to form the standing plate.

[0008] 3. A roof structure in which the snow guard / rain gutter described in 1 or 2 above is placed and fixed to the upper surface of the eaves of the roof of a building.

[0009] 4. A roof structure as described in 3. above, in which the bottom panel is pressed and fixed onto the roof by a locking plate. Effect of the Invention

[0010] 1. The snow guard / rain gutter of the present invention is a snow guard / rain gutter that is placed and fixed on the eaves of a roof that is inclined downward toward the eaves side, and includes a flat base plate that is fixed on the roof, an inclined plate that is connected to one end of the base plate on the eaves side and inclined upward toward the eaves side, a standing plate that is connected to the inclined plate and extends downward from the upper end of the inclined plate and stands on the roof, and a bottom plate that is connected to the lower end of the standing plate and fixed on the roof, so that it has sufficient strength against large amounts of snow and promotes snow melting, and exhibits excellent functions as a rain gutter. That is, the inclined plate and the standing plate act as a snow guard against large amounts of snow, and the gutter groove portion formed by the intersection of the inclined plate and the base plate plays the role of a rain gutter. In addition, air flows through the space with a triangular cross section formed by the inclined plate, the standing member, and the roof, making it easier for snow to melt on the inclined plate and the base plate.

[0011] 2. When the snow guard / rain gutter is made up of a main body member and a support member joined to the main body member, the main body member is integrally formed with a flat base plate, an inclined plate connected to one end of the base plate on the eaves side and inclined upward toward the eaves side, and a first standing plate connected to the inclined plate and extending downward from the upper end of the inclined plate to stand on the roof, and the support member is integrally formed with a second standing plate and a bottom plate connected to the lower end of the second standing plate and fixed to the upper surface of the roof, the main body member and the support member can each be formed by bending a single plate, so that the snow guard / rain gutter can be efficiently made. Furthermore, by surface-joining the first standing plate and the second standing plate, the inclined plate can be reliably supported by the two plates, making it easier to withstand large amounts of snow.

[0012] 3. A roof structure in which a snow guard / rain gutter is placed and fixed to the upper surface of the eaves of a building's roof will have sufficient strength to withstand large amounts of snow and will promote snow melting, making the roof structure an excellent performer of rain gutters.

[0013] 4. When the bottom panel of the snow guard / rain gutter is pressed and fixed onto the roof with a locking plate, the snow guard / rain gutter can be securely placed and fixed onto the roof. [Brief description of the drawings]

[0015] The present invention will be described in detail below with reference to Figures 1 to 10. Note that the present invention is not limited to the specific examples shown in these figures, and can be modified in various ways depending on the purpose and application. [1] Snow guard / rain gutter The snow guard / rain gutter 1 embodies the present invention. As shown in Figures 1 and 7, the snow guard / rain gutter 1 is characterized by comprising a flat base plate 11 fixed onto the roof, an inclined plate 13 connected to one end of the base plate 11 on the eaves side and inclined upward toward the eaves side, an erect plate 15 connected to the inclined plate 13, extending downward from the upper end of the inclined plate 13 and erected on the roof, and a bottom plate 17 connected to the lower end of the erected plate 15 and fixed onto the roof.

[0016] There are no particular limitations on the shape of the substrate 11 as long as it is flat, but since it is placed on the upper surface of the eaves of the roof, it is usually rectangular. The inclined plate 13 is a member that is connected to one end of the base plate 11 on the eaves side, inclined upward toward the eaves side, and is generally rectangular in shape. In this way, the gutter groove portion 12 (see FIG. 8) having an inverted triangular cross section formed by the intersection of the inclined plate 13 and the base plate 11 functions as a rain gutter. The inclined plate 13 also functions as a snow guard.

[0017] 2, the angle θ between the base plate 11 and the inclined plate 13 can be appropriately adjusted depending on the inclination of the roof on which the snow guard / rain gutter 1 is placed and fixed. Therefore, the angle θ is not particularly limited and can be, for example, 140 to 160 degrees. 8, air flows through space 18, which is formed by inclined plate 13, standing plate 15, and covering plate 75 and has a triangular cross section, and this facilitates melting of snow on inclined plate 13 and base plate 11. In particular, the air in space 18 warms up easily during the day, making it easier for snow to melt and less likely for icicles to form. It is also possible to melt the snow by providing a heating device such as a heater in the space 18.

[0018] The material of the snow guard / rain gutter 1 is not particularly limited, but is preferably a metal with high thermal conductivity to promote the melting of snow and frozen rainwater. For example, aluminum is preferably used. Note that the entire snow guard / rain gutter 1 does not have to be made of aluminum, and for example, any one or two of the base plate 11, the inclined plate 13, and the standing plate 15 may be made of aluminum.

[0019] The snow guard / rain gutter 1 can be made up of a main body member 10 and a support member 20 joined to the main body member 10, as shown in FIG. The main body member 10 is integrally formed of a flat base plate 11, an inclined plate 13 connected to one end of the base plate 11 on the eaves side and inclined upward toward the eaves side, and a first standing plate 15a connected to the inclined plate 13, extending downward from the upper end of the inclined plate 13, and standing on the roof. Further, the support member 20 is integrally formed with the second standing plate 15b and a bottom plate 17 that is connected to the lower end of the second standing plate and fixed to the upper surface of the roof. The first standing plate 15a and the second standing plate 15b are surface-joined to form the standing plate 15. As described above, the snow guard / rain gutter 1 consisting of the main body member 10 and the support member 20 is formed.

[0020] (Manufactured) There is no particular limitation on the method for producing the snow guard / rain gutter 1. For example, as shown in FIG. 2, a main body member 10 is produced by folding a single metal plate twice to form a base plate 11, an inclined plate 13, and a first upright plate 15a. Moreover, the support member 20 is produced by bending one metal plate to form the second standing plate 15b and the bottom plate 17. The second standing plate 15b is made to have the same shape as the first standing plate 11a. The inner surface of the first standing plate 15a of the main body member 10 and the outer surface of the second standing plate 15b of the support member 20 are overlapped and surface-joined to form the standing plate 15. The method of surface joining is not particularly limited, and known means such as screws, bolts and nuts, and rivets can be used. As described above, the snow guard / rain gutter 1 consisting of the main body member 10 and the support member 20 is manufactured.

[0021] [2] Roof structure using rain gutters that also serve as snow guards The following describes a roof structure using the snow guard / rain gutter 1. As shown in Fig. 7, in a roof having a flat portion 50, which is the roof body, with a fascia board 51 and a gable board 55, the snow guard / rain gutter 1 is placed and fixed on a covering board 75 that covers the tip of the flat portion 50 from the tip to the top. As shown in Fig. 7, the snow guard / rain gutter 1 is provided with a through hole 11h for drainage. There are no particular limitations on the size or shape of the through hole, but it is generally circular in order to connect to the vertical gutter 80, and its diameter is usually 50 to 70 mm.

[0022] To mount and fix the combined snow guard and rain gutter 1 on the roof, the bottom plate 17 is pressed against the covering plate 75 by the engaging plate 60 and fixed to the flat portion 50 by nails 91, as shown in FIG. Furthermore, the end portion on the ridge side of the base plate 11 of the snow guard / rain gutter 1 is pressed and fixed by the pressing portion 70a of the covering plate member 70. With this configuration, the snow guard / rain gutter 1 can be reliably fixed to the roof, and rainwater or the like can be reliably prevented from leaking through the flat portion 50. As shown in Figs. 7 and 9, a vertical drain 80 for drainage is connected to the through hole 11h. The snow guard / rain gutter 1 is installed over the entire upper surface of the eaves of the roof with its horizontal ends connected together.

[0023] (action) The operation of the snow guard / rain gutter 1 configured as above and the roof structure using the same will now be described. As shown in Fig. 10, as snow gradually accumulates on the roof, snow accumulation portion 95 pushes toward snow guard / rain gutter 1 and is pressed against inclined plate 13, which acts as a snow guard. When the snow melts and turns into rainwater, gutter groove portion 12, which has an inverted triangular cross section and is formed by the intersection of base plate 11 and inclined plate 13, serves as a rain gutter. In addition, air flows through space 18, which is formed by inclined plate 13, standing plate 15, and the roof and has a triangular cross section, so that snow on inclined plate 13 and base plate 11 melts easily. In addition, when there is a lot of snow, snow that climbs over the inclined plate 13 falls under the eaves. In this case, since the corners 14 are formed at an acute angle, they function as cutters that cut off the accumulated snow, and the snow that climbs over the inclined plate 13 is cut off and is promoted to fall under the eaves.

[0024] Moreover, even when there is no snow and the structure is used only as a rain gutter, the gutter groove portion 12 having an inverted triangular cross section naturally functions as a rain gutter.

[0025] [3] Other effects of the embodiment Other effects and advantages of the snow guard / rain gutter 1 and the roof structure using the same according to the embodiment will be described below. With conventional gutters, when a ladder is leaned against it, there is a risk that the ladder will press against the gutter and damage it, but with the roof structure of this embodiment, the snow-guard / gutter 1 is formed integrally with the roof structure, and there is no conventional gutter, so this problem does not arise.

[0026] In addition, the snow guard / rain gutter 1 can be easily seen from the roof and is easy to inspect. And unlike conventional rain gutters, cleaning can be done from the middle of the roof, making cleaning work on the roof safe. Furthermore, when removing snow from the roof, the inclined plate 13 provides a foothold for the worker, preventing him from falling. In addition, the inclined plate 13 acts as a jump platform for snow sliding across the roof, accelerating the falling of snow and making it easier to remove. Furthermore, with a roof structure using the snow guard / gutter 1, conventional gutters are not necessary, so there is no damage to the eaves caused by the construction of gutters, and maintenance of the eaves is easier.

[0027] Furthermore, even in areas with heavy snowfall where rain gutters cannot be installed in order to prevent damage to the gutters due to snow accumulation, the snow guard / gutter 1 functions as a rain gutter without being damaged by snow accumulation. Even if the vertical gutter becomes clogged with garbage, snow, etc. and the flow of rainwater becomes poor, the rainwater overflows from the gutter groove portion 12, thereby preventing damage that occurs with conventional rain gutters. Furthermore, since the snow guard / rain gutter 1 is integrated with the roof, it is strong against strong winds such as typhoons, so you can rest assured.

[0028] Furthermore, when snow and volcanic ash accumulate, it is difficult to clean the accumulated volcanic ash with conventional gutters. On the other hand, the snow guard / gutter 1 can be easily cleaned from above the water, reducing the risk of workers falling off the roof and improving work efficiency. In addition, in the case of a tiled roof, by placing and fixing the snow guard / rain gutter 1 to the eaves tip, the tiles are less likely to be blown around by strong winds such as typhoons, and the tiles are less likely to slip off, compared to a roof with tiles placed and fixed up to the eaves tip. The tiles are also less likely to fall off during an earthquake. [Explanation of symbols]
