TECHNICAL FIELD The present invention relates to a technique for draining a balcony.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open No. 64-27329 has been known as a device for draining a veranda. As shown in FIG. 4 , this Japanese Utility Model Laid-Open No. 64-27329 has a drain groove 40 formed in the upper surface of an end of a veranda 1, and a through hole 41 whose upper end opens to the drain groove 40. The drainage fitting 42 provided with a drain is attached to the through hole 41, the drain gutter 43 is connected to the drainage fitting 42, the water flowing from the veranda 1 is caused to flow into the drainage groove 40, and the drainage fitting 42 is drained from the drainage groove 40. It was supposed to drain in the order of the downspout 43.

Another conventional example is an example in which a drainage groove is not provided on the upper surface of the veranda, and in this case, as shown in FIG. 5 , the veranda 1 is vertically arranged at the corner of the upper surface of the veranda 1. A through hole is formed through which a drain fitting 42 having a drain is attached to the through hole, and the water on the veranda 1 is concentrated on the drain fitting 42 side without providing a drain groove. Was installed toward the drain fitting 42 side with an inclined gradient as shown by the arrow in FIG . And balcony 1
The water flowing from was collected in the drain fitting 42 and drained by the vertical gutter 43 connected to the drain fitting 42.

[0004]

However, in the former example of the former, the drain groove 40 is formed on the upper surface of the veranda 1.
Therefore, the practical usable area of the veranda 1 is narrowed, and the drainage groove is unsightly because it can be seen from the top of the veranda 1. Further, the protruding length of the protruding end portion protruding from the building body of the veranda 1 is the drainage. The protrusion length is longer than the length that allows the groove to be formed in the upper surface portion. Also,
A drain groove is formed on the upper surface of the veranda 1, and the drain fittings 42 and the downspout 43 penetrate vertically through the projecting end of the veranda 1, so that water may leak into the building.

In the latter conventional example, instead of providing the drain groove in the veranda 1, it is necessary to make the upper surface of the veranda 1 incline downward toward one place (that is, the drain fitting 42). , The convenience of using the upper part of the balcony becomes worse,
Further, the work of forming an inclined gradient toward one place as shown by an arrow in FIG. 5 on the upper surface of the veranda 1 is troublesome. Also in this conventional example, the protruding length of the protruding end protruding from the building body of the veranda 1 needs to be longer than the length that allows the drainage fitting to penetrate and be attached to the upper surface portion. It is something that will end up. Further, since the drainage fitting 42 and the downspout vertically penetrate through the protruding end portion of the veranda 1, water may leak into the building.

The present invention has been made in view of the above-mentioned problems of the prior art. It is not necessary to form a drainage groove on the upper surface of the veranda, and the upper surface of the veranda can be widely used. There is no need for water to enter the building side, and there is no need for time-consuming construction with an inclined slope that collects water from the upper surface of the balcony toward one location. The main issue is to be able to decorate the drainage gutter, and another issue is to make drainage from the veranda smooth and to make the drainage gutter as small as possible. It is still another object to provide a drainage structure of a veranda that can be made invisible and can prevent balls and the like from entering the drainage gutter from the top of the balcony.

[0007]

Between the tip of the protruding end portion 3 and between the cover material 8 and the outer piece 5.
It is characterized in that a water passage gap 9 is formed between them. With such a configuration, it is possible to drain water from the veranda 1 from the protruding end portion 3 of the veranda 1 to the drainage gutter 4 arranged along the protruding end portion 3, and as a result, the total length of the protruding end portion 3 The water can be drained from the veranda 1, and there is no need to make a slope that slopes down toward one location on the upper surface of the veranda 1, and construction is easy and drainage is smooth. In this case, a drainage groove may be formed on the upper surface of the veranda 1 as in the conventional case, or the veranda 1 or the building body 2 may be formed.
There is no need to install drainage fittings or down gutters through the drainage gutter 4 and the drainage gutter 4 is located outside the projecting end portion 3 of the veranda 1, so rainwater does not enter the veranda 1 or the building body. It can be structured. Then, the projecting end portion 3 of the veranda 1 can be hidden by the drainage gutter 4, and the appearance of the building can be improved. In addition, it is possible to prevent spilling of a ball or the like from the top of the veranda 1 by a portion of the upper portion of the outer piece 5 of the drainage gutter 4 which protrudes above the veranda 1. In addition, the inside of the drain gutter 4 is covered by the cover material 8.
The cover material 8 can be made invisible to the user.
