DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an example of the embodiment shown in FIG. 1 will be described. The water collector 1 is formed in the shape of a rectangular box with an open top surface, and eaves trough insertion openings 2 having a shape corresponding to the shape of the eaves trough 4 are drilled in the opposite side walls of the water collector 1. At the center of the bottom surface of the water collector 1, a cylindrical drain pipe 3 is hung downward. Ends of eaves gutters 4 are inserted into and connected to eaves gutter insertion openings 2 on both sides of the water collector 1, respectively, and vertical drains are connected to the drain pipe 3. On the outer circumference of the bottom surface of the water collector 1, there is provided a slope 5 which becomes lower toward the inner circumference. The slope 5 is formed with a steep slope to some extent. A horizontal plane portion 6 is formed between the slope 5 and the outer periphery of the opening at the upper end of the drainage pipe 3.

Then, the rainwater W is drained on the plane portion 6
A guide rib 7 that guides inward is provided so as to project upward. A plurality of guide ribs 7 are provided around the opening at the upper end of the drain pipe 3 at appropriate intervals. The guide rib 7 has a spiral curve shape when seen from a plane. Further, the guide rib 7 has a long guide rib 7a and a short guide rib 7b, and long guide ribs 7a are provided at positions corresponding to both ends of the eaves gutter insertion opening 2 in the width direction. A guide rib 7b having a short length is provided at a position corresponding to the center of the gutter insertion opening 2 in the width direction. Further, since the guide rib 7a has a spiral curved shape, one surface is a convex curved surface 9 and the other surface is a concave curved surface 10. However, the convex curved surface 9 faces one end in the width direction of the eaves gutter insertion opening 2. And
The concave curved surface 10 faces the other end.

When the rainwater W flows from the eaves gutter 4 into the water collector 1 as shown by the arrow a in FIG. 1, the rainwater W is guided by the guide ribs 7 and circulates as shown by the arrow c in FIG. As described above, the water flows into the drain pipe 3 and then flows into the drain pipe 3 so as to be smoothly drained into the drain pipe 3.

Next, an example of the embodiment shown in FIG. 2 will be described. This example is also basically the same as the above example, and only different points will be described. In the case of this example, instead of providing the guide rib 7, the slope 8 is provided in a mortar shape. A slope 5 is provided on the outer circumference of the bottom surface of the water collector 1, and a slope 8 is formed between the slope 5 and the opening at the upper end of the drainage pipe 3 so as to cover the entire circumference. The slope 5 and the slope 8 are the slope 5
Is steep and the slope 8 is gentle.

When the rainwater W flows from the eaves trough 4 into the water collector 1 as shown by the arrow a in FIG. 2, the rainwater W is guided by the slope 5 and has a mortar shape as shown by the arrow d in FIG. The slope 8 guides the drainage pipe 3 to gather in the center of the drainage pipe 3, flows into the drainage pipe 3, and is smoothly drained into the drainage pipe 3.

According to the first aspect of the present invention, the end portion of the eaves trough is inserted into and connected to the eaves trough insertion opening provided on the side wall of the box-shaped water collector having an open upper surface, and the water collector is connected. In a drainage structure of a water collector in which a drainage pipe connected to a vertical gutter is hung from the bottom of the drainage pipe, a guide rib for guiding rainwater into the drainage pipe is projected on the bottom face of the water drainage pipe around the upper end opening of the drain pipe. Therefore, it is possible to guide the rainwater that has flowed from the eaves trough into the water collector into the drain by guiding it with the guide ribs, and to guide the rainwater into the drain and smoothly discharge it. . Also guide
