Further, in the above structure, the drainage opening of the waterproof pan is a screen-like opening provided over substantially the entire length of the drainage groove, so that the above object can be more remarkably achieved. is there.

[0010]

[Operation] With the above structure, rainwater on the floor of the balcony flows into the drain from the surface of the waterproof pan having a waterproof function, and from the drain opening provided in the drain to the eaves installed below the drain opening. Can be dropped and drained. Note that the eaves gutter is directly connected to a vertical gutter as in the normal eaves gutter, and is optionally connected via a call gutter to be drained to the ground.

The rainwater or the like in the drains of a plurality of waterproof pans is not collected and dropped into a specific drainage opening, but is dropped into the eaves trough from the drainage opening of each waterproof pan, so that the drainage grooves and drainage openings are less likely to be clogged. Also, the number of call gutters 6 required is small,
The number of vertical gutters 5 is small, the construction is easy, and the appearance is not damaged.

Furthermore, by making the drainage opening a screen-like opening wide over substantially the entire length of the drainage groove, it is possible to more completely prevent clogging of the drainage groove and the drainage opening.

EXAMPLES A drainage structure for a balcony waterproof pan according to the present invention will be described below with reference to examples.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a perspective view showing an embodiment using a plurality of waterproof pans. Portions which are the same as or correspond to those of the conventional example are denoted by the same reference numerals.

There is a drainage groove 2 on one side of the waterproof pan 1,
A drainage opening 3 is provided at the bottom of the drainage groove 2. And
The eaves gutter 7 is installed below the drainage opening 3 of the waterproof pan 1.

The waterproof pan 1 is molded and manufactured by a plastic material having water resistance and having no problem in strength and moldability.
Alternatively, molding with fiber-reinforced plastic is preferable, but other materials and manufacturing methods may be used.

The drainage groove 2 is formed so that rainwater or the like on the surface of the waterproof pan 1 can naturally flow in. Even if it is provided near the edge on the eaves side, it is provided at a position slightly away from the edge. Good. The cross-sectional shape of the drainage groove 2 may be square or semicircular.

In the embodiment shown in FIG. 1, the drainage opening 3 has a large number of slit-shaped openings lined up at the bottom of the drainage groove 2 over substantially the entire length of the drainage groove 2 to remove foreign matters formed in a wide screen. It is an opening. The screen-shaped opening may be formed by a large number of small holes.

Of course, the drainage opening 3 may be formed in one or both end portions of the drainage groove 2 or in the middle portion as one or a plurality of openings having an appropriate size.

The waterproof pan 1 of the present embodiment is laid on the floor of the balcony, and the eaves gutter 7 is provided below the drainage opening 3 so that rainwater from the drainage opening 3 can be received. Alternatively, it is attached to a building portion to form the embodiment.

In addition, the drain gutter 6 is connected to an appropriate part of the eaves gutter 7 and the vertical gutter 5 is connected to the drain gutter 6 to complete the construction of the drainage facility from the balcony.

With the above structure, rainwater or the like on the floor of the balcony flows into the drain groove 2 from the surface portion of the waterproof pan 1 having a waterproof function, and is installed below the drain opening 3 from the drain opening 3 provided in the drain groove 2. It can be dropped into the eaves gutter 7 and drained. The vertical gutter 5 is directly connected to the eaves gutter 7 as in the case of a normal eaves gutter, or is connected via the slamming gutter 7 if necessary, and drained to the ground.

Unlike the conventional structure in which rainwater or the like in the drains of a plurality of waterproof pans is collected and dropped from one drain opening into a gutter, the water can be dropped into the eaves gutter 7 from the drain opening 3 of each waterproof pan 1. Since the amount of wastewater and the amount of dust per drainage opening are smaller than in the conventional example, the drainage groove 2 and drainage opening 3
Never clogs. Also, the eaves gutter will not be blocked because only the water that has passed through the drainage opening 3 flows. Further, since the required number of the call gutters 6 is small and the number of the down gutters 5 is small, the construction is easy and the appearance is not spoiled.

Further, by forming the drainage opening 3 in a wide screen shape over substantially the entire length of the drainage groove 2, it is possible to more completely prevent the drainage groove 2 and the drainage opening 3 from being clogged.

[0025]

As described above, according to the present invention, rainwater or the like on the balcony floor flows into the drain from the surface portion of the waterproof pan, and from the drain opening to the eaves gutter installed below the drain opening. Can be dropped and drained. In addition, a vertical gutter is directly connected to the eaves gutter as in the normal eaves gutter, and if necessary, it is connected via a gutter to drain it to the ground.

Unlike the conventional example in which rainwater in drainage channels of a plurality of waterproof pans is collected and dropped from the drainage opening into a gutter, since each waterproof pan can be dropped into an eaves gutter for drainage, the drainage amount per drainage opening The amount of dust is smaller than in the conventional example, and it is possible to prevent clogging of drainage channels and drainage openings. Also, since the required number of sluices is small and the number of vertical gutters is small, the construction is easy and the appearance is not damaged.

Further, by forming the drainage opening as a screen-like opening widely provided over substantially the entire length of the drainage groove, it is possible to more completely prevent clogging of the drainage groove or the drainage opening.
