BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage lid mounting structure which is disposed along a wall of a building.

[0002]

2. Description of the Related Art Conventionally, in a drainage basin arranged along the wall of a building, a lid A is attached to an upper portion of a drainage basin body 1 formed in a cylindrical shape.
In order to mount the receiving member 3, an inverted L-shaped receiving member 30 is fixed to the upper part of the inner surface of the peripheral wall 1 a of the drainage body 1.
The locking piece 3, which is suspended from the peripheral end of the cover plate 2, is mounted on the mounting piece 30 a of the cover plate 2.
The upper end is flush with the upper end.

[0003]

However, in the above-described conventional example, it is necessary to fix the receiving member 30 as a separate member to the inner surface of the peripheral wall 1a in order to mount the cover A, The rain which sometimes falls on the upper surface of the cover plate 2 travels down the outer surface of the peripheral wall 1a as shown by an arrow a in the figure since the upper surface of the cover plate 2 and the upper end of the peripheral wall 1a are in a flush state. Therefore, there is a problem that the outer surface of the main body 1 is easily soiled.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and it is possible to reduce the number of parts to reduce the production cost and to prevent rainwater from flowing down the outer surface of the main body. It is intended to provide a lid mounting structure for the drain mast.

[0005]

According to the present invention, in order to achieve the above object, a cover plate 2 is disposed at an upper opening of a drainage body 1 formed in a cylindrical shape, and a cover plate 2 is provided from a peripheral end of the cover plate 2. The locking piece 3 hanging downward is drained. The draining piece 3 contacts the inner surface of the peripheral wall 1 a of the main body 1, and the locking portion 4 provided on the locking piece 3 and the drainage body 1 are drained.
And a locked portion 5 provided on the peripheral wall 1a of the locking pieces 3, the circumferential
The walls 1a are each partially bent so as to be engaged with each other.
A water drainage piece 6 is formed in a shape, and is disposed on an upper part of a peripheral wall 1a of the drainage main body 1 so as to protrude above the cover plate 2 over the entire circumference .

[0006]

[Action] Then, the lid 2
, The locking piece 3 of the lid 2 and the peripheral wall 1a are smelled.
Shape that is partially bent and engages with each other
To prevent the cover plate 2 from slipping upward.
Configuration can be easily obtained, and moreover, on the peripheral wall 1a.
The part is a drain piece 6 protruding above the lid plate 2 to form a lid.
The rainwater on the plate 2 is drained and travels along the outer surface of the peripheral wall 1a of the main body 1.
To flow downward and prevent the outer surface of the peripheral wall 1a from becoming dirty.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments. As shown in FIG. 2, the drainage trough is formed by projecting a receiving cylinder 7 from the side of the drainage trough body 1 formed by a cylindrical body toward the side, and a lid A is provided at an upper opening.
And a downspout 8 is connected to the lower opening. The receiving cylinder 7 is attached to the side of the main body 1 by welding (MIG welding). A large number of air inlets 9 for sucking air into the drainage main body 1 are provided on an upper side surface of the drainage main body 1, and a connecting portion 10 for connecting the downspout 8 is provided at a lower portion. The connecting portion 10 can connect a plurality of types of downspouts 8 having different diameters. In the illustrated embodiment, the connecting portion 10 includes a first connecting portion 10a and a second connecting portion 10b. I have. In other words, the thicker downspout 8 can be connected to the drainage body 1 at the first connecting portion 10a, and the narrower downspout 8 can be connected to the draining body 1 at the second connecting portion 10b. It has become.

The lid A attached to the upper opening of the drainage main body 2 is a lid plate 2 formed in a thin disk shape as shown in FIG.
The main body is constituted by the locking piece 3 vertically provided below the peripheral end of the cover plate 2. A plurality of through holes 11 are provided on the upper surface of the cover plate 2, and the through holes 11 draw air into the main body 1 and drain rainwater accumulated on the upper surface of the lid 2. To act. The lid A is adapted to be attached to the body 1 for draining the locking piece 3 so as to abut against the inner surface of the peripheral wall 1a of the main body 1, and the locking portion 4 provided on the locking piece 3 and the peripheral wall. The drainage is attached to the main body 1 without causing a displacement due to engagement with a locked portion 5 provided on the inner surface of 1a. The locking portion 4 provided on the locking piece 3 is formed by a locking recess 12 which is formed by recessing a part of the locking piece 3 inward, and is provided on an inner surface of the peripheral wall 1a. The stop portion 5 is formed by a locking projection 13 which is formed by projecting the inner surface of the peripheral wall 1a partially inward.
Here, in the illustrated embodiment, the locking portion 4 is formed by the locking recess 12, and the locked portion 5 is formed by the locking projection 13.
However, the locking portion 4 may be formed by the locking convex portion 13 and the locked portion 5 may be formed by the locking concave portion 12.
At the upper part of the peripheral wall 1a of the drain body 1, there is provided a drain piece 6 projecting above the lid plate 2 in the engaged state, and the drain piece 6 drains rainwater on the lid plate 2. 1 so that it does not flow downward along the outer surface.

As shown in FIG. 2, the connecting member 16 is inserted into the drain pipe 15 protruding from the wall surface 14, and the connecting member 16 is fixed to the wall surface 14 with the fixing member 17, as shown in FIG. 16 is connected to the receiving cylinder 7 protruding from the main body 1 and a cover 18 is provided so as to cover the connecting member 16.
Is attached to the wall surface 14. A lid A is attached to the upper part of the drainage body 1 so that the locking part 4 of the locking piece 3 and the locked part 5 of the peripheral wall 1a engage with each other.

[0010]

[Effect of the Invention] As described above, in the present invention, a lid plate is disposed at the upper opening of the drainage muffler body formed in a cylindrical shape, and the locking pieces vertically suspended from the peripheral edge of the lid plate are drained. The locking part provided on the inner surface of the peripheral wall of the main body and the locking part provided on the locking piece and the locked part provided on the peripheral wall of the draining main body are formed by the locking piece and the peripheral wall, respectively.
Formed into a shape that is partially bent and engages with each other
And, since the draining piece projecting upward from the cover plate at the top of the peripheral wall of the catch basin body it is provided over the entire circumference, drainage or
To put the lid on the upper opening of the main body,
