BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin disposed along a wall of a building.

[0002]

2. Description of the Related Art Conventionally, a drain basin disposed along the wall of a building is mainly composed of a drain basin body 2 formed in a substantially cylindrical shape. The downspout 10 is connected to the connecting portion 12 so that the downspout body 2 is connected to the downspout 10. The connecting portion 12 to which the downspout 10 is to be connected is formed, for example, as shown in FIG. As shown in (a), the auxiliary member 60 formed in a substantially L shape is connected by welding.

[0003]

However, in the above-described conventional example, the bottom plate portion a of the connecting portion 12 and the lower end of the drainage body 2 are substantially flush with each other in a horizontal plane. As a result, the rainwater flowing on the outer surface of the drainage main body 2 is transmitted from the lower end of the drainage main body 2 to the bottom plate portion a, and as a result, the downspout 10 is connected to the connecting portion 12. There is a problem in that rainwater is transmitted to the outer surface and the outer surface of the downspout 10 is soiled.

An object of the present invention is to solve the above-mentioned problems, and the rainwater flowing on the outer surface of the drain basin can be drained at the lower end of the drain basin, and the rain gutter connected to the connecting portion can be drained. It is intended to provide a drainage basin without transmitting on the outside.

[0005]

According to the present invention, in order to achieve the above object, a connecting portion 12 to which a downspout 10 is connected is provided at a lower portion of a substantially cylindrical drainage basin main body 2, and this connecting portion is provided. The auxiliary connecting cylinder 40 attached to the lower opening of the body 2 and having a smaller diameter than the body 2.
The flange piece 40b protrudes outward from the upper end of the auxiliary connecting cylinder body, and the folded back piece 40a extends downward from the tip of the flange piece 40b. The draining piece 50 is formed by abutting the tip of the folded piece 40a separated from the lower end of the body 2 of the drainage body 2 and connecting the folded piece 40a and the lower end of the body 2 of the drainage body.

[0006]

[Action] Then, the folded piece 40a and the draining body 2
The water drain piece 50 formed by connecting the lower end of the main body 2 is separated from the outer surface of the auxiliary connecting cylinder 40 by the presence of the flange piece 40b, and the rainwater flowing down the outer surface of the main body 2 is drained. It will fall below the lower end of the water drainage piece 50 without going down the outer surface of 40.

Constitutes the subject. A plurality of through-holes 20 are provided on the upper surface of the lid 18, and the through-holes 20 suck air into the drain body 2 and drain rainwater collected on the upper surface of the lid 18 and drain into the main body 2. To act. Here, the lid 18 provided with the through hole 20 is provided.
The upper surface of the cover 18 is inclined obliquely downward toward the center of the cover 18 so that rainwater on the cover 18 does not flow along the outer surface of the main body 2 which drains. I have. The connecting cylinder 19 provided at the lower part of the lid 18 is located one step inward from the lower end of the lid 18 extending downward. The outer diameter of the connecting cylinder 19 is the same as the inner diameter so that it can be inserted into the upper opening of the drainage body 2, while the outer diameter of the connecting cylinder 19 is formed the same as the outer diameter of
As a result, the lower end of the lid 18 protrudes outward from the connecting cylinder 19.

When the lid member 9 is drained by the outwardly protruding portion, the connecting tube 19 is drained when the lid member 9 is attached to the upper part of the main body 2. The lid 18 is positioned while being inserted into the upper opening of the main body 2. A positioning step 21 is formed, and the lid member 9 is positioned so that the positioning step 21 is in contact with the upper end of the main body 2 for draining.
As shown in FIG.
By screwing the fixing member 23 into the screw hole 22 provided in the connecting cylinder 19, the lid member 9 and the drainage main body 2 are connected. Here, when connecting the lid member 9 and the drainage body 2 with the fixing member 23, the positioning step 21 is brought into contact with the upper end of the drainage body 2 so that the drainage hole 20 is formed in the body 2. Position and connecting tube 1
The position of the screw hole 22 provided in the screw 9 is matched with the position of the screw 18, and the positioning step 21 is drained to abut on the upper end of the main body 2 to position the lid 18 and screw the fixing tool 23. The positioning of the through hole 20 and the screw hole 22 to be inserted is also performed.

When the drainage body 2 is attached to the wall 3, the drainage pipe 4 to which the drainage body 1 of the drainage body 2 is connected has a connecting member 24 attached thereto. It is adapted to be connected to the connecting cylinder 5 of the member 24. As shown in FIG. 5 and FIG.
The main body is constituted by the connecting tube 5 fitted to the drain pipe 4 protruding from the outside and the mounting piece 25 protruding from the end of the connecting tube 5 along the circumferential direction. Piece 25
