Abstract

PURPOSE:To discharge a small amount of rain and refuse by rapid flow down of rainwater and to improve the scene of eaves by a method wherein an upper coupling rising at the front side of eaves and having an inclining bottom and an elbow having one end connected to a drain port and the other end connected to the inlet of the upper end of a vertical gutter are contained in an eaves ceiling and built integrally with a building. CONSTITUTION:A bottom 11 inclining upward toward the front side of eaves B is mounted on an eaves gutter A and connected to an upper coupling 1. Further, one end of an elbow 2 is connected to a drain port 12 of the lower part of the wall on the rear side of the upper coupling 1 and the other end is connected to an inlet 3 arranged at the upper end of a vertical gutter 4. Further, the elbow 2 is contained in an eaves ceiling C and built integrally with a building. This constitution causes flow down of rainwater from the upper coupling 1 as a velocity of flow is increased and rapid discharge of a small amount of rainwater and attendant refuse. The elbow 2 is contained in the eaves ceiling C and eaves are neatly finished and an effect to improve a scene is increased.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter drainage device, and more particularly to a gutter drainage device housed inside an eave ceiling and integrated with a building.

[0002]

2. Description of the Related Art Conventionally, a gutter from an eaves gutter or a water collector to a gutter has one end connected to the lower bottom of the eaves gutter or the water collector, and the other end having an upper end of the drainage port of the gutter. Since it was connected to, the gutter was exposed along the lower surface of the eaves, which hindered the installation work and was easily damaged, and spoiled the view of the eaves. Also, if the eaves gutter has a flat bottom, it will easily cause rainwater to accumulate and cause water leakage when connected as described above.

[0003]

DISCLOSURE OF THE INVENTION The present invention is to solve the above-mentioned problems, and its gist is to connect to an eaves gutter having a bottom portion that is inclined upwardly toward the front side of the eaves. , One end of which is connected to a drain outlet provided at the lower part of the rear side wall of the upper joint, and the other end of which is a gutter facing the receiving box attached to the upper end of the vertical gutter, which is stored inside the eaves ceiling. It is a gutter drainage device characterized by being formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. 1 is an exploded perspective view showing an embodiment of the present invention, FIG. 2 is a partially cutaway side view showing a state in which the present invention is attached, and FIG. 3 is an enlarged sectional view taken along the line X--X of FIG. FIG. 4 is an enlarged cross-sectional view taken along line X-X of another embodiment of the present invention.

The invention is shown in exploded perspective view in FIG. 1 and in FIG.
As shown in the partially cut-away side view, the eaves gutter A has a side cross-sectional shape that matches the outer contour of the eaves gutter A that has a bottom portion 11 that rises and slopes toward the front side of the eaves tip B.
It comprises a top gutter 1 equipped with 2 and a gutter 2 having one end connected to the drainage port 12 of the top gage 1 and the other end facing the receiving box 3 attached to the upper end of the vertical gutter 4. Is a gutter drainage device housed inside the eaves ceiling C.

That is, the upper joint 1 used in the present invention has a side sectional shape corresponding to the outer contour of the eaves trough A having a bottom portion 11 which rises and slopes toward the front side of the eaves tip B, and has a lower side wall on the rear surface thereof. It also has a drainage port 12. The bottom 11
May be a flat slope as shown in the figure, or may be inclined stepwise downward toward the rear side of the eaves tip B (not shown).

Then, one end of the sluice gutter 2 is externally connected to the drainage port 12 projecting toward the eaves at the lower part of the rear side wall of the upper joint 1, and the discharge port 21 of the other end is connected to the drain gutter 4 of the vertical gutter 4. The receiving box 3 attached to the upper end of the receiving box 3 and the receiving box 3 for receiving the discharge port 21 of the calling gutter 2 are both shown in FIG.
As shown in FIG. 3 and an enlarged cross-sectional view taken along the line XX of FIG. 2, it is completely housed inside the eaves ceiling C. As described above, it is preferable that the flume 2 housed inside the eaves ceiling C has a water gradient that descends from the front side of the eaves at one end to the rear side of the other end.

As a mode in which the gutter 2 is housed inside the eaves ceiling C, in addition to the above, as shown in the enlarged sectional view of FIG.
A concave groove C-1 is formed in the eave ceiling C where the gutter 2 is arranged,
The gutter 2 is arranged such that at least the lower surface of the gutter 2 is substantially flush with the lower surface C-2 of the eaves ceiling C.

According to the present invention having the above-described structure, as shown in FIG. 2, rainwater flowing down from the roof flows in the eaves trough A having a bottom portion 11 which rises and slopes toward the front side and forms a sectional shape with the eaves trough A. In the same way, increase the momentum from the drainage port 12 of Kamui 1 toward the receiving box 3 as shown by the arrow, and accelerate the flow velocity in combination with the water gradient of the gutter 2. Is discharged to. In addition, since the gutter 2 is housed inside the eaves ceiling C, the eaves are neat and the finished landscape is greatly improved.

[0010]

Since the present invention has the above-mentioned structure, it has the following effects. That is, according to the present invention, the rainwater flows down from the top at a faster flow rate, so that a small amount of rainwater and accompanying dust can be promptly discharged. Since it is stored in, the eaves are neat and the finished landscape is greatly improved.
