Abstract

PURPOSE:To prevent rain water from freezing and to prevent a gutter from being broken or deformed by a snow guard or the like, by leading exhausted hot air into a ventilation duct from the inside of a building, and by enhancing the strength of the component members. CONSTITUTION:Eaves 1b on the upper front surface, and eaves, a cutwater and the like are provided in the lower part, and a plurality of ventilating holes 3a are formed in the rear surface with a partition member 3 being laid so as to define an ventilating duct part 2. Then, thus obtained structure is attached to the eaves part facing the end part of the room member of a building W so that the ventilating duct part 2 is communicated with an exhaust port 5 of each of rooms M and the attic R through the partition member 3. Then, a ventilating fan as a ventilating mechanism, 6 is positioned in the end part of the eventilating duct part 2, and a ventilating port L is formed in each of the rooms M. Further, hot air exhausted from the building is led into the ventilating duct part 2 and then is discharged outside through the ventilating mechanism 6.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter and a rain gutter device that can be attached to, for example, the eaves of a building.

0002

[Prior Art] Conventionally, this type of rain gutter and rain gutter device has a structure in which a gutter material with a U-shaped cross section is attached to the eaves of a building, and rainwater flowing from the roof is drained by the gutter material. Are known.

By the way, in areas with heavy snowfall, in order to prevent rainwater from freezing, electric heaters are installed in rain gutters, or an internal gutter system is adopted in which gutters are placed inside buildings, and measures are taken to prevent damage to rain gutters. Therefore, the number of gutter holders has been increased and reinforced, and the rain gutters have been constructed so that they can be removed during the winter.

0004

[Problems to be Solved by the Invention] However, in the case of the electric heater type in the above conventional structure, the electricity bill is high and the running cost is high, and in the case of the internal gutter type, although freezing can be prevented by the warm air in the room, This has the disadvantage that problems remain in construction and maintenance.

[0005]

[Means for Solving the Problems] The present invention aims to solve these disadvantages, and the gist thereof is to provide a rain gutter member capable of draining rainwater with an air supply/exhaust duct portion that can communicate with the inside of the building. The present invention relates to an integrally formed rain gutter and a rain gutter device in which the rain gutter is arranged at the eaves of a building. This rain gutter is provided with a partitioning member that allows partitioning and communication between the supply and exhaust duct and the inside of the building.

[0006]

[Operation] Rainwater is drained by the rain gutter member, and exhaust heat air inside the building passes through the air supply and exhaust duct portion formed integrally with the rain gutter member. The exhaust heat air inside the building flows through the partition member to the supply/exhaust duct section.

[0007]

[Embodiment] FIGS. 1 to 5 show an embodiment of the present invention, and FIG.
4 to 4 show the first embodiment, and FIG. 5 shows the second embodiment.

In the first embodiment shown in FIGS. 1 to 5, 1 is a rain gutter member, and the rain gutter member 1 is integrally formed with an air supply/exhaust duct portion 2. A partitioning member 3 having a generally concave cross-sectional shape, having a gutter portion 1a on the upper surface, an eaves portion 1b on the front surface, an eave ceiling portion 1c on the lower surface, a drainage portion 1d on the upper edge, and a plurality of ventilation holes 3a on the rear surface.
are attached to form the air supply/exhaust duct section 2.

This rain gutter member 1 is attached to the eaves facing the end of the roof material 4 of the building W, and the air supply/exhaust duct portion 2 is connected to the exhaust outlet 5 of each room M through the partition member 3 or to the attic. A supply/exhaust mechanism 6 including a supply/exhaust fan is connected to the end of the supply/exhaust duct section 2, and a ventilation port L is provided in the wall of the room.

Since this first embodiment has the above-mentioned configuration, rainwater flowing down on the roof material 4 is received by the gutter portion 1a of the rain gutter member 1 and drained, while exhaust heat air inside the building W is drained from the rain gutter. Part 1
It passes through the air supply/exhaust duct part 2 formed integrally with the air supply/exhaust duct part 2 and is discharged to the outside via the air supply/exhaust mechanism 6. In this case, the exhaust heat air inside the building W passes through the ventilation hole 3a of the partition member 3. The rainwater will flow to the supply/exhaust duct section 2, and therefore the rainwater flowing through the gutter section 1a can be prevented from freezing due to exhaust heat.
Furthermore, by integrally forming the rain gutter member 1 and the air supply/exhaust duct part 2, the section modulus of the rain gutter member 1 is increased, and the strength of the rain gutter member 1 can be improved. and deformation can be prevented.

[0011] Furthermore, the rain gutter member 1 can be appropriately designed so that, for example, the eave roof portion 1c can be integrally formed.

The second embodiment shown in FIG. 5 shows a different structure, and while the first embodiment is used for general roofs,
In this case, the structure is for a folded roof, and therefore the side door portion 1e of the folded roofing material 4 is integrally formed, and a condensation catch gutter material 7 is placed below the valley of the folded roofing material 4 to receive condensation water. A condensation gutter section 8 is formed between the drain section 1c and the surface door section 1e. This second embodiment also provides the same effects as the first embodiment.

The shape and structure of the rain gutter member 1 and the air supply/exhaust duct 2 are designed with appropriate changes.

[0014]

[Effects of the Invention] As described above, according to the present invention, rainwater is drained by the rain gutter member, while exhaust heat air inside the building passes through the supply/exhaust duct portion formed integrally with the rain gutter member. The exhaust heat air inside the building flows through the partition members to the supply/exhaust duct, and this exhaust heat prevents rainwater from freezing. By forming the rain gutter, the section modulus of the rain gutter member increases, the strength of the rain gutter member can be improved, and breakage and deformation of the rain gutter member due to snow eaves etc. can be prevented.

[0015] As described above, the intended purpose can be fully achieved.
