Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage structure for a balcony provided in an opening on a second floor or more.

[0002]

[Prior Art]

 Balconies are often installed at the openings on the second and higher floors of buildings. The floor of this balcony has a considerable area from the sill of the opening to prevent raindrops that bounce off the floor or water droplets that are blown by the wind from splashing from the opening when it rains. It is usually low, and the floor slope is fairly steep so that no water film is formed on the floor surface, and the drainage groove on the floor surface is usually placed only on the side edge along the handrail. is there.

[0003]

[Problems to be solved by the device]

 However, the conventional balcony has safety drawbacks. In other words, there is a high level difference between the floor and the threshold of the opening, and the floor slope is too steep, and it is often dangerous to stumble upon entering or leaving the room or to stagger in the sky. However, in order to improve this condition, if the steps on the floor surface are reduced and the slope is made gentle, the raindrops and water droplets from the floor surface are more likely to be scattered toward the opening side. The present invention reduces the level difference on the floor surface and makes the slope gentle to allow safe access between the opening and the balcony, but even if raindrops or water droplets are scattered from the floor to the opening side. It aims at providing the drainage structure of the balcony which can suppress.

[0004]

[Means for Solving the Problems]

 The balcony drainage structure according to the present invention is a balcony drainage structure projecting from an opening in an outer wall, and includes a drainage groove on a side edge along a handrail on the floor of the balcony and the floor surface. The drain groove on the side edge side along the opening, and the groove lid of the water permeable structure that covers the upper surface of the drain groove on the side edge side along the opening are configured.

[0005]

[Action]

 Since the drainage ditch on the balcony floor is also located along the side edge along the opening, there is little difference between the sill of the opening and the balcony floor surface, and even if the floor slope is gentle, the floor of the balcony is rainy. The water film formed on the surface flows into the drainage groove on the side edge side along this opening, does not reach the edge of the opening, and the water film itself becomes thin, which causes wind-up of water droplets. Is greatly reduced. Also, among raindrops that bounce off on the balcony floor surface, which come from a portion near the edge of the opening that easily jumps into the opening, the floor of this portion becomes a drainage groove on the side edge side along the opening, Drastically decrease. The drainage groove on the side edge along this opening is covered with a grooved lid with a permeable structure to prevent it from getting caught in the drainage groove when entering and exiting the balcony floor surface, and it has a permeable structure. Therefore, the action of suppressing the scattering of raindrops and water drops continues.

【Example】

 1 is a vertical sectional view showing an embodiment of the balcony drainage structure of the present invention, FIG. 2 is an enlarged perspective view of a main part of the balcony drainage structure of FIG. 1, and FIG. It is an expansion perspective view of the principal part of the drainage structure of Luconi. In the figure, 1 is a balcony, 2 is an opening, 3 is a floor surface, 4 is a handrail, 5 is a drainage groove on the side edge along the handrail 4, 6 is a drainage groove on the side edge along the opening 2, Reference numeral 7 is a groove lid, and 8a and 8b are downspouts. As shown in FIG. 1, the drainage structure of the balcony according to the present embodiment is applied to a balcony 1 of a normal form. The balcony 1 is integrally formed in the opening 2 of the reinforced concrete outer wall including the floor surface 3 and the handrail 4. In this case, the handrail 4 is a handrail wall made of reinforced concrete, a so-called parapet, but here, a handrail made of a normal metal and a parapet are referred to as a handrail.

The floor 3 is a long and narrow quadrilateral, and the height of the floor 3 is almost equal to the threshold of the opening 2, and a gentle slope is provided from here to the handrail 4. The drainage structure of this balcony 1 is configured as follows. That is, a drainage groove 5 on the side edge along the handrail is provided on the handrail 4 side of the floor surface 3, and a drainage groove 6 on the side edge side along the opening portion is provided on the opening 2 side of the floor surface 3. Set up. All of these drainage channels have a normal U-shaped cross section with an open upper side. Among them, the drainage channel 6 on the side edge along the opening covers the upper surface of the drainage channel 6, and has a water-permeable structure. A lid 7 is attached. As shown in FIG. 2, the groove lid 7 is made of a stainless steel plate and has a large number of round holes arranged to be opened to form a water permeable structure. Each end of the side drainage groove 5 along the handrail and the side edge drainage groove 6 along the opening is connected to the lower vertical gutters 8a and 8b as shown in FIG.

Since the balcony 1 of the present embodiment is provided with the drainage structure, there is little step between the floor of the opening 2 and the floor 3, and even if the floor 3 has a gentle slope, the floor 3 It is possible to prevent raindrops and water droplets from splashing toward the opening 2 side. This is because the drainage groove 6 on the side edge along the opening is arranged on the floor surface 3 and is further covered with the groove lid 7 having the water permeable structure. Due to the existence of the side drainage grooves 6 along the opening, the splash of raindrops from the floor surface 3 to the opening 2 side is greatly reduced, and two drainage grooves 5, 5 6 is provided, the water film thickness on the floor surface 3 is remarkably thin, and the wind-up of water drops is reduced. As a result, infiltration of raindrops and water droplets into the opening 2 is suppressed. Further, the floor surface 3 having a small step and a gentle slope can be formed, which makes it extremely safe to move in and out of the floor surface 3 and the opening 2, and the upper surface of the drainage groove 6 on the side edge side along the opening is water-permeable. Since it is covered with the groove lid 7 of the structure, there is no danger of catching a foot on the groove edge, and since it is the groove lid of the water permeable structure, it does not hinder the action of suppressing the raindrops and water drops.

Another embodiment of the drainage structure of the balcony of the present invention shown in FIG. 3 will be described. This is prepared by preparing a groove member 9 made of hard plastic to be fitted in an inscribed state on the inner surface of the drain groove 6 on the side edge side along the opening in FIG. 1, and the groove of the water-permeable structure is formed on the upper surface of this groove member 9. This is a combination of the lid 7. The groove lid 7 is also made of hard plastic, and as shown in FIG. 3, a large number of diagonal fins 71 are arranged in parallel along the longitudinal direction on the upper surface of the perforated plate. With such a structure, the bounce of a small amount of raindrops on the upper surface of the groove lid 7 can be reliably suppressed. Further, the frictional resistance of the inner surface of the drain groove 6 on the side edge side along the opening is reduced, and the drainage flow is improved. The rest of the structure, operation, etc. are the same as those of the above-mentioned embodiment, and the explanation thereof is omitted.

The drainage structure of the balcony of the present invention can be modified in various ways other than the above embodiment. For example, the water-permeable structure of the groove lid may be a wire mesh arrangement, and a simple structure may be possible. Further, the same effect can be obtained even if the balcony is made of metal or wood instead of reinforced concrete structure.

[0011]

[Effect of the device]

 According to the drainage structure of the balcony according to the present invention, even if the difference in level between the floor surface of the balcony and the opening is reduced and the floor surface slope is made gentle, raindrops and water droplets are prevented from entering the opening, and the opening is reduced. Access between the department and balcony is extremely safe.
