Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to drainage strainers. For example, it relates to a drainage strainer provided on a floor such as a balcony, an outer corridor, or a parapet where rainwater is poured.

[0002]

[Background Art] Since rainwater pours onto the floors of balconies, outer corridors, parapets, etc., a drainage structure is provided to collect and drain the rainwater. For example, on the floor of the balcony, there is a water gradient that gradually inclines downward as it moves away from the main body of the building, and a drain groove is formed with a water gradient on the downstream side of this water gradient. There is a drainage structure that accommodates a drainage strainer.

As a conventional drainage strainer, as shown in FIG. 5, a cup-shaped drainage strainer 13 is provided directly above a drain pipe 124A vertically buried in a terminal water reservoir of a drainage groove.
1A is covered, or, as shown in FIG. 6, a drain pipe 124B horizontally embedded in the terminal water reservoir of the drainage groove is provided with a triangular cylindrical drainage strainer 131B at the inlet. .

[0004]

However, in any of the above-described structures, the drainage strainers 131A and 131B are higher than the upper surfaces of the floors 113A and 113B, and thus they are likely to cause tripping when walking. In particular, the structure shown in FIG. 6 has a problem that water tends to collect around the drainage strainer 131B (see the portion B in FIG. 6). An object of the present invention is to provide a drainage strainer that eliminates such conventional problems and does not cause tripping when walking.

[0005]

A drainage strainer according to the present invention is a drainage strainer provided at a terminal water reservoir of a drainage ditch formed with a water gradient on a floor on which rainwater or the like is poured. And a strainer main body which is housed in a section and whose upper end surface is formed into a flat surface having substantially the same height as the floor. In the present invention, the strainer body may be formed in a box shape by punching metal, and the end face connected to the drain groove has a width dimension substantially the same as the width of the drain groove and the deepest depth of the drain groove. The drainage inlet having a height dimension lower than the height may be formed.

[0006]

According to the drainage strainer of the present invention, since the strainer main body whose upper end surface is formed to be a plane having substantially the same height as the floor is housed in the terminal water reservoir of the drainage groove, that is, Since the upper end surface of the strainer main body is substantially flush with each other, it does not cause a trip when walking on the floor. Also, if the strainer body is formed into a box shape with punching metal, rainwater that has flowed directly onto the water reservoir due to the water gradient on the floor can flow from the holes in the punching metal into the water reservoir, and the strainer body can be simplified. There is an advantage that can be configured. If the drainage inlet of the strainer main body that has the same width as the width of the drainage groove and a height dimension lower than the deepest depth of the drainage groove is formed on the end face, the drainage introduction It is possible to prevent the passage of dust mixed with rainwater that has flowed through the drainage channel by the mouth. Therefore, it is possible to prevent dust from clogging in the drain pipe.

It is composed by.

The balcony unit 5 is a handrail wall provided in a U-shape along the periphery (long side away from the building body 1 and short sides on both sides) of a base frame (not shown) formed in a rectangular frame shape. A floor 13 having a water gradient 12 and having a water gradient inclined downward as it goes to the long side away from the building body 1. On the floor 13, as shown in FIG.
A drain groove 21 is formed on the downstream side of the water gradient along the long side direction with a predetermined water gradient, and a rectangular water reservoir 22 is provided at the end of the drain groove 21 on the downstream side of the water gradient. A horizontal drain pipe opening 23 for connecting a horizontal drain pipe 24 attached to the short side of the balcony unit 5 is horizontally formed on the side wall of the water reservoir 22, and a drainage strainer 31 is provided. Is dropped and stored.

As shown in FIG. 3, the drainage strainer 31 has a strainer main body 32 formed in a box shape by a punching metal made of stainless steel. That is, the strainer main body 32 has an upper surface 33 whose upper end surface is formed on a flat surface having substantially the same height as that of the floor 13, and is bent at right angles downward from both side edges of the upper surface 33, and then the inside of each other. Side portions 34, 35 bent at right angles toward one side, a front surface portion 36 bent at a right angle downwards from the front edge of the upper surface portion 33, and downward from a rear edge of the upper surface portion 33. It is formed in a box shape having a rear surface portion 37 that is bent at a right angle toward the inside and then bent at a right angle toward the inside.

The drain groove 21 is formed on both side surfaces 34 and 35.
Drainage inlets 38 and 39 each having a width dimension substantially the same as the width and a height dimension lower than the deepest depth of the drainage groove 21. Further, in the center of one side surface portion 35,
As shown in FIG. 4, a slot 40 for connecting the horizontal drain pipe 24 is formed.

With the above-described structure, rainwater and the like that fall on the floor 13 flow according to the water gradient of the floor 13 and flow into the drain groove 21. Rainwater in the drain 21 is
The water flows in the drain groove 21 according to the water gradient and is drained from the water reservoir 22 to the horizontal drain pipe 24 through the drain strainer 31. At this time, the relatively large dust mixed in the rainwater is caused by the drainage inlets 38, 39 of the drainage strainer 31.
Since the passage is blocked by the above, clogging in the horizontal drain pipe 24 can be prevented.

Since 1 is stored, the floor 13 and the upper end surface of the drainage strainer 31 are substantially flush with each other, which does not cause a trip when walking on the floor. Moreover, since the drainage strainer 31 only needs to be dropped into the water reservoir 22, no special mounting screws or the like are required, and mounting and removal can be easily performed.

Further, since the strainer main body 32 of the drainage strainer 31 is formed in a box shape by punching metal, it can be manufactured extremely easily. That is, since it is only necessary to bend and form the punching metal into a box shape, the manufacturing can be extremely simplified. Moreover, rainwater or the like that has flown directly onto the water reservoir 22 due to the water gradient of the floor 13 can flow into the water reservoir 22 through the holes of the punching metal. In addition, since stainless steel panning metal is used,
Hard to rust.

Both side surface portions 3 of the strainer body 32
Since the drainage inlets 38 and 39 having substantially the same width dimension as the drainage groove 21 and the height dimension lower than the deepest depth of the drainage groove 21 are formed in the drainage inlets 4 and 35,
By means of 9, it is possible to prevent the passage of dust and the like mixed in the rainwater flowing along the drain groove 21. Therefore, it is possible to prevent dust from clogging in the horizontal drain pipe 24.

Although the present invention has been described above with reference to the preferred embodiments, the present invention is not limited to these embodiments, and modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the balcony unit 5
