JPH07103650B2 - 2nd floor roof rainwater drainage structure - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a second-floor roof rainwater drainage structure, and more particularly to a drainage structure configured so that rainwater on a second-floor roof of a building does not fall directly onto the floor surface of a balcony below the floor and is dispersed. is there.

[Conventional technology]

Rainwater W that fell on the roof of the second floor with a balcony downstairs,
Conventionally, for example, a gutter as shown in Japanese Utility Model Publication No. 61-33769 is provided to drain water, or FIG. 3 (a),
As shown in the perspective view of the main part in (b), in (a),
Cut the lower end of the vertical gutter 1 from the eaves gutter toward the balcony floor surface F, or use the elbow 2 at the lower end as shown in (b).
It was configured to be bent by a straight line to drop directly onto the floor surface F for drainage, and from another place on the floor surface F through the eaves gutter on the first floor or directly from the vertical gutter.

[Problems to be Solved by the Invention]

However, in the conventional drainage structure of this kind as described above, since the rainwater W on the second floor is dropped directly onto the balcony floor surface F, dust and dirt accumulated on the roof surface on the second floor are absorbed into the floor surface F. If it adheres to the upper surface and deteriorates the appearance, and if there is an extremely large amount of rain or if there are obstacles such as snow or dead leaves in the rainwater drainage direction on the floor surface F, a water pool is generated on the floor surface F. I was afraid to make it happen.

The present invention has been made in consideration of the problems of the conventional drainage structure of this kind as described above, and does not stain the balcony floor surface due to the above-mentioned reasons, and also prevents obstacles on the same floor surface F. The purpose of the present invention is to provide a drainage structure capable of draining the vertical rainwater W from the roof surface of the second floor regardless of the state.

[Means for Solving the Problems]

Therefore, in the present invention, a vertical gutter for guiding rainwater on the roof surface of the second floor of the building penetrates through the gutter receiving grating provided on the floor surface of the downstairs balcony, and is arranged under the floor surface. It is intended to achieve the above-mentioned object by being configured to be connected to the 1st floor eaves gutter via.

[Action]

With the drainage structure according to the present invention as described above, the rainwater from the roof surface of the second floor is drained on the origami plate 6 without directly dropping through the gutter to the floor surface of the balcony, so that the dust and dirt on the roof surface of the second floor. Does not adhere to the balcony floor surface, and since the rainwater drainage burden on the balcony floor surface is limited to the balcony surface, it will be drained under the floor regardless of obstacles on the floor surface, There is no fear of pooling water on the floor.

〔Example〕

 Hereinafter, the present invention will be described based on Examples.

FIG. 1 is a perspective view of a main part of an embodiment of this type of rainwater discharge structure according to the present invention, and FIG. 2 is a cross-sectional view of the main part of the balcony floor part.

(Structure) In FIG. 1, F shows a balcony floor surface, and P shows a building outer wall panel. Rainwater W from the roof surface on the second floor (not shown) is guided to the vicinity of the balcony floor surface F through the vertical gutter 1, where the turn socket 3, the elbow 2, the vertical gutter member 1, the elbow 2,
And without dropping directly to the floor surface F through the vertical gutter member 1,
It is configured to be guided to the eaves gutter 7 on the first floor through a hole on the gutter receiving grating 4 provided on the floor surface F and a folding plate 6 under the floor plate 5 shown in FIG. Rainwater W of eaves gutter 7
It is guided to the ground by a vertical gutter (not shown).

In this case, a floor reinforcing material (not shown) and a floor board 5 are laid on the folding plate 6, but only the portion into which the vertical gutter 1 is dropped,
The floor reinforcing material and the floor board 5 are small in size. The gutter receiving grating 4 is fixed to the space formed by this with a small screw, a rivet, an adhesive agent, or the like.

Further, in FIG. 2, the floor surface (floor finish surface) F on the floor board 5
Is laid all over the balcony floor except where the vertical gutter 1 enters the gutter receiving grating 4 hole.

Also, depending on the relative positions of the gutter 1 and the gutter receiving grating 4 from the second floor, the gutter 1 may be directly guided to the folding roof directly without using the turn socket 3 and each elbow 2. Is.

If the turn socket 3 and the elbow 2 are used, it is convenient to remove this part for checking the gutter clogging.

〔The invention's effect〕

As described above, according to this type of drainage structure of the present invention, rainwater from the roof surface of the second floor is drained through the origami plate without being dropped directly onto the balcony floor surface through the vertical gutter. Therefore, the dust and dirt on the roof surface of the second floor carried by the rainwater does not adhere to the balcony floor surface, and the rainwater drainage load on the balcony floor surface is limited to the balcony surface. Irrespective of obstacles, there is no fear of water pools on the floor.
