Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drainage structure for a balcony, and more particularly, to a drainage structure for a balcony having an overflow pipe that drains when the water level in the balcony reaches a predetermined water level.
[0002]
[Background]
In recent years, the construction of barrier-free houses taking into account the elderly and wheelchair users is becoming mainstream. This barrier-free house is designed to make the level difference and inclination of the floor as small as possible. For example, the sliding door sill is designed to be the same level as the floor, or the level difference between the Western-style room and the Japanese-style room is eliminated. This is realized. Moreover, the flow of barrier-free is being applied not only in indoor spaces but also outdoors such as balconies.
[0003]
By the way, in the conventional balcony, the drainage groove was formed along the handrail provided along the edge of the balcony. In addition, the overflow pipe that assists drainage when the drainage process is not in time and the water level in the balcony reaches a predetermined level has been piped outside the balcony through the headboard provided at the lower end of the handrail.
[0004]
[Problems to be solved by the invention]
For this reason, inconvenience occurred in the following points in making the balcony barrier-free.
First, in the conventional drainage structure, since the drainage groove is provided along the edge of the balcony, it is necessary to provide a large water gradient with a height difference from the interior space to the outside of the balcony (the projecting direction). In addition, since the overflow pipe is provided below the handrail, the handrail mounting position is higher than the balcony floor surface, giving a feeling of pressure in appearance. That is, it is a structure in which it is difficult to obtain a sense of unity between the indoor space and the balcony that are required with the barrier-free operation.
[0005]
Therefore, an object of the present invention is to provide a drainage structure for a balcony where a sense of unity between the balcony and the indoor space can be easily obtained.
[0006]
[Means for Solving the Problems]
  In order to solve the above technical problem, the present invention has the following configuration. In other words, the balcony drainage structure of the present invention has a balcony in the building, a column cover that covers the periphery of the column standing in and below the balcony, and an upper end that is open at a position higher than the floor of the balcony. An overflow pipe, and when the water level in the balcony reaches a predetermined water level, a drainage structure for the balcony that drains through the overflow pipe,
  The overflow pipe extends downward from the building,
  In the balcony, a drainage groove is formed from one side to the other side,
  Drainage collected in the drain is,in frontIt is discharged to the bottom of the building through a gutter constructed as a separate body from the overflow pipe.
  The scissors are provided with scissors provided along pillars erected below the balcony, and a portion connecting the scissors and the drainage grooves,
  Said overflow pipe and竪 樋Is provided inside the pillar cover.
[0007]
According to the drainage structure of the present invention configured as described above, the overflow pipe is disposed inside the column cover, and when the water level in the balcony reaches a predetermined water level, the drainage in the balcony is It is drained outside the balcony through an overflow pipe hidden in the pillar cover.
[0008]
Thus, in the drainage structure of the present invention, since the overflow pipe is hidden by the column cover, it is possible to perform piping without exposing the overflow pipe in the balcony. Moreover, since the overflow pipe is moved into the column cover, the height of the handrail provided along the edge of the balcony can be sufficiently reduced.
Therefore, it becomes easy to obtain a sense of unity between the balcony and the indoor space required with the barrier-free operation.
[0009]
  Also, BaIt is good also as a structure in which the water gradient which goes down to the said drain groove is formed from the front side of Luccony and the back side of a balcony, respectively.
[0010]
  In this configuration, BaWater gradients are attached from the front side of Luccony and the back side of the balcony toward the drain. Therefore, drainage in the balcony can be efficiently performed without providing a large water gradient from the back side of the balcony toward the front side of the balcony. Moreover, since the height difference is minimized on the front side of the balcony where the handrail is provided, the distance from the balcony floor surface to the lower end of the handrail is shortened. For this reason, a sense of unity between the handrail and the balcony is born, and an open impression can be given.
[0011]
Further, it is desirable that the drainage groove formed from one side of the balcony toward the other side is disposed near the center in the width direction of the balcony.
Here, the width direction is a direction corresponding to the protruding direction of the balcony. When a drainage groove is provided near the center of the balcony in the width direction, water formed from the front side of the balcony and the back side of the balcony. It becomes possible to suppress the height difference of the gradient to the minimum necessary height difference.
[0012]
  In addition, the balcony is formed in a plurality of sections in the longitudinal direction, and the pillars of the building are provided between the sections, and the drainage groove has a water gradient descending toward the nearest pillar.DoIt is good also as a structure.
[0013]
In this configuration, by providing a water gradient toward the pillar provided between the compartments, the water gradient that should be continuously inclined from one side of the balcony to the other side is inherently one of the compartments. One can cope with each.
Therefore, the inclination of the floor surface of the balcony can be minimized.
Moreover, since the drainage of each section can be performed without performing a waterproof treatment between the sections, the labor related to the construction of the drainage grooves can be greatly reduced.
[0014]
  Also,Extended down the buildingThe overflow pipe passes between compartments.RuIt is good also as a structure. That is, in this configuration, since the overflow pipe is provided between the sections, the overflow pipe can be installed without processing the floor surface of the balcony. Moreover, since the drainage in the balcony drained from the overflow pipe immediately flows down to the building, the drainage is smoothly performed.
[0015]
In addition, a handrail is provided at the edge of the balcony, and a headboard that also serves as a handrail base is provided below the handrail, and the upper end of the overflow pipe is at a position lower than the upper end surface of the headboard. It is good also as a structure which opens.
In this configuration, since the overflow pipe is opened at a position lower than the upper end surface of the headboard, it is possible to suppress drainage from overflowing outside the balcony beyond the headboard.
[0016]

[0043]
As described above, according to the present embodiment, the inner balcony 16 includes the first balcony 16A, the second balcony 16B, and the third balcony 16C, and the drainage grooves 45, 46, 47 is formed, even if the inner balcony 16 is a long one that straddles the three building units 13A to 13C, the wastewater flows from the two inner balconies 16A and 16B toward the single column portion 51. Therefore, drainage is performed efficiently.
[0044]
Moreover, since the partitioned inner balconies 16A to 16C are respectively provided in separate outer building unit 13A, central building unit 13B, and outer building unit 13C, after combining building units 13A and the like on the site, Since it is only necessary to construct a connecting portion between adjacent inner balconies 16A, etc., the work on site is reduced.
[0045]
In addition, an overflow pipe 80 is provided in the first pillar portion and the second pillar portion 52 on the second floor, and the upper end surface thereof is opened at a position lower than the headboard 21, so that the first drainage groove 45, the second Wastewater that cannot be treated in the drainage groove 46 and the third drainage groove 47 and overflows from the upper surface of the coffin member 67 is discharged from the overflow pipe 80 through a gap formed between the column cover 35 and the receiving member 63.
Therefore, the inner balcony 16 can be drained efficiently, and there is little possibility of overflowing the floor 60 indefinitely.
[0046]
Moreover, since the overflow pipe 80 is disposed in the column cover 35 and is hidden from view from the outside, the overflow 80 pipe can be disposed without conspicuous.
Further, since the overflow pipe 80 is moved into the pillar cover 35, the headboard 21 can be formed low, and the height of the handrail 20 can be suppressed low. Accordingly, it is possible to relieve the appearance of the oppressive feeling given by the handrail 20.
[0047]
In addition, drainage grooves 45, 46, 47 are provided in the center in the width direction of the inner balcony 16, and water gradients from the front side of the inner balcony 16 and the inner side of the inner balcony 16 toward the drainage grooves 45, 46, 47, respectively. Therefore, the drainage water in the inner balcony 16 can be collected without a large water gradient from the inner side of the inner balcony 16 toward the front side of the inner balcony 16.
Therefore, the height difference between the floor surface 60 of the inner balcony 16 and the living room K can be made sufficiently small.
Further, since the height difference is minimized on the front side of the inner balcony 16 where the handrail 20 is provided, the distance from the floor surface 60 to the lower end of the handrail 20 is shortened.
For this reason, a sense of unity between the handrail 20 and the inner balcony 16 is born, giving an open impression.
Thus, it becomes easy to obtain a sense of unity between the inner balcony 16 and the living room K (indoor space), which is required with the barrier-free operation.
[0048]
Moreover, since the overflow pipe 80 penetrates between the partitioned inner balconies 16A to 16C and extends below the building, the installation of the overflow pipe 80 becomes easy. Moreover, since the waste water drained from the overflow pipe 80 immediately flows down to the lower part of the building, the drainage is smoothly performed.
[0049]
The above-described embodiment is merely an embodiment of the present invention, and details thereof can be changed as needed.
For example, in the said embodiment, the waste_water | drain of the inner balcony 16 flows in toward the 1st pillar part 51 of the 2nd floor from the 1st drainage groove 45 of the 1st balcony 16A, and the 2nd drainage groove 46 of the 2nd balcony 16B. The third drainage channel 47 of the third balcony 16C and the second rooftop drainage channel 56 of the second terrace 17B are the second on the second floor. Although the pillar part 52 and the second pillar part 42 on the first floor are used, the present invention is not limited to this, and both may be reversed. That is, the first drainage groove 45 of the first balcony 16A and the second rooftop drainage groove 56 of the second terrace 17B are connected to the first pillar part 51 on the second floor and the first pillar part 41 on the first floor, and the second The second drain groove 46 of the balcony 16B and the third drain groove 47 of the third balcony 16C may be connected to the first column portion 41.
[0050]
In the embodiment, the drainage of the first terrace 17A and the third terrace 17C is performed by the first rooftop drainage basin 90 and the third rooftop drainage basin 96 disposed along the outer wall of the building, respectively. However, it is not limited to this configuration. Similarly to the second rooftop drainage basin 95, the first rooftop drainage basins 90 and 96 are connected to the first pillar 51 on the second floor and the first pillar 41 on the first floor. It is good also as a 3rd rooftop drainage tub continuing to the 2nd pillar part 52 of the 2nd floor, and the 2nd pillar part 42 of the 1st floor. In this case, the connected drain pipes from the balconies 16A and the like may be connected to these roof drains using tees or the like.
In this way, since there is no drainage dredge that appears outside the building, the appearance is clean and the design is excellent.
[0051]
【The invention's effect】
As described above, according to the present invention, since the overflow pipe disposed below the handrail is moved into the column cover, the height of the handrail can be sufficiently reduced.
Moreover, since the drainage groove is formed in the center of the balcony in the width direction and the water gradient from the front side and the back side of the balcony toward the drainage groove is provided, the height difference in the balcony can be minimized.
Therefore, it becomes easy to obtain a sense of unity between the balcony and the indoor space required with the barrier-free operation.
