Description

[Technical Field]

[0001] The present disclosure relates to a balcony structure with a planting area. [Background technology]

[0002] For example, Patent Documents 1 and 2 disclose techniques for providing planting structures adjacent to the verandas of buildings. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-002588 [Patent Document 2] “WITH HARAJUKU” Shinkenchiku July 2020 issue P42 Summary of the Invention [Problem to be solved by the invention]

[0004] The configuration described in Patent Document 1 allows direct access to the balcony area and the planting area at the end of the balcony from the indoor area where residents spend their time, making access to the planting area easy. However, there is a risk that children, especially small children, could use the planting area as a foothold to climb over the balcony railing located further outside the planting area and fall outside the building.

[0005] Furthermore, in the configuration described in Patent Document 2, a "first planting space" is provided at approximately the same height as the balcony section used by building users at the tip (outside) of the balcony section, and a "second planting space" is provided further to the tip (outside) of that, with the floor height lower than that of the "first planting space." In the configuration described in Patent Document 2, the plants in the "first planting space" are placed right up to the balcony section's handrail, which can reduce the amount of light entering the balcony section and the sense of openness of the view that users can enjoy.

[0006] Furthermore, in the configuration of Patent Document 2, while there is little risk of users of the balcony area falling out of the building, in order to perform maintenance such as selecting plants or replanting them, it is necessary to use a gondola from outside the building, or a ladder or aerial work platform, which not only makes the work difficult to do, but also makes the work dangerous and often expensive.

[0007] Furthermore, neither Patent Document 1 nor Patent Document 2 discloses any special measures for drainage of the planted areas. Therefore, there is a risk that rainwater will accumulate in the planted areas or overflow during heavy rain. Furthermore, even if gutters or the like were installed, there is a risk that the appearance of the building exterior will be marred.

[0008] The object of the present disclosure is to provide a balcony structure with a planting installation area that can reduce the risk of users of the balcony area falling, has good drainage in the areas where the plants are placed, has a good appearance on the exterior of the building, and allows good lighting to enter the balcony area and provides users with a sense of openness in the view.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0019] (First embodiment) FIG. 1 is a plan view showing a first embodiment of a balcony structure 1 with a planter according to the present disclosure. FIG. 2 is a cross-sectional view of the balcony structure 1 taken along the line indicated by the arrow AA in FIG. 1. Note that hatching has been omitted from the cross-section in FIG. 2. FIG. 3 is a cross-sectional view of the balcony structure 1 taken along the line indicated by the arrow BB in FIG. 1. The following figures, including FIGS. 1 to 3, are schematic diagrams, and the size and shape of each part are exaggerated or omitted as appropriate for ease of understanding. For example, in FIG. 3, the slope of the drainage ditch 23 is emphasized. The following description uses specific numerical values, shapes, materials, etc., but these may be modified as appropriate.

[0020] The balcony structure 1 with a planting installation section according to the present disclosure comprises a balcony section 10, a planting installation section 20, an exterior wall hanging wall section 30, a movement restriction section 40, a drainage path 50, and a planting container 60.

[0021] The balcony section 10 is an outdoor or semi-outdoor area with at least one side exposed to the outside, i.e., a portion not covered by a roof or wall, and is also called a balcony. The balcony section 10 of this embodiment is provided with a parapet 11 at its outdoor end. Here, "parapet" generally refers to "the rising portion at the boundary between the exterior wall and the roof in a flat roof with no slope." However, the parapet 11 of this embodiment is appropriately low, prioritizing safety, and the movement restriction section 40 (described below) is sufficiently high so that even if a person (especially a child) steps onto the balcony section, they cannot climb over the movement restriction section 40. The floor of the balcony section 10 is also provided with a drainage slope so that rainwater and other water that falls on the balcony section can be collected in a drainage section (not shown).

[0022] The floor 21 of the planting installation section 20 is positioned lower above ground than the balcony section 10, allowing plants to be installed thereon. At the tip end of the planting installation section 20 (the side farther from the balcony section 10) is provided a planting container fixing section 22 for fixing a planting container 60, which will be described later. In the illustrated embodiment, the planting container fixing section 22 fixes the planting container 60 using anchor bolts and nuts embedded in the planting installation section 20, but other fixing means may also be used to fix the planting container 60.

[0023] Furthermore, a drainage groove 23 and a water collection section 24 are provided on the floor surface 21 of the planting installation section 20. The drainage groove 23 is formed in a groove shape and, in this embodiment, is arranged along the exterior wall hanging wall section 30. The drainage groove 23 has a drainage gradient that is lower on the water collection section 24 side to allow drainage water such as rainwater to flow away. Furthermore, the floor surface 21 has a drainage gradient that is lower on the drainage groove 23 side to allow drainage water such as rainwater to flow into the drainage groove 23.

[0024] The water collection section 24 has a sand-settling section 24a and an island-shaped section 24b, and is arranged adjacent to the outer wall hanging wall section 30 in an approximately rectangular shape when viewed from above (as shown in Figure 1).

[0025] The sand-settling section 24a is provided on the outer periphery of the water collection section 24 at a position other than the outer wall hanging wall section 30 side, and is connected to the drainage groove 23. The sand-settling section 24a is configured to be recessed lower than the part (connection end 23a) to which the drainage groove is connected.

[0026] The island-shaped portion 24b is formed at a height equal to or lower than the height of the portion (connection end 23a) where the drainage groove 23 connects to the sand-settling portion 24a, and higher than the sand-settling portion 24a. The island-shaped portion 24b is surrounded by the sand-settling portion 24a at a position other than the outer wall hanging wall portion 30 side. That is, the island-shaped portion 24b is arranged with the sand-settling portion 24a sandwiched between it and the drainage groove 23. The drainage path 50, which will be described later, is connected to the island-shaped portion 24b.

[0027] As described above, the planting installation area 20 is provided with a drainage structure that includes a drainage slope on the floor surface 21, the drainage groove 23, the sand settling area 24a, and the island-shaped area 24b, and that directs drainage to the drainage path 50. This allows rainwater and excess water left over from irrigation in the planting installation area 20 to be properly drained and prevented from leaking out. Furthermore, the sand settling area 24a prevents fine sand, soil, and the like from flowing into the drainage path 50.

[0028] In addition, a walkway 25 is provided on the floor 21 of the planting installation area 20 between the drainage ditch 23 and the planting container 60 so that people can walk along it. Workers who perform various maintenance tasks can walk along this walkway 25.

[0029] The exterior wall hanging wall portion 30 is connected to the end of the balcony portion 10 and also to the floor surface of the planting installation portion 20.

[0030] The movement restriction section 40 is a structure that restricts the movement of people between the balcony section 10 and the plant-installation section 20. In this embodiment, the movement restriction section 40 is a fence installed at the end of the balcony section 10. The movement restriction section 40 also has a lockable door 41. This door 41 may be installed in a location facing an area occupied by indoor users of the building, such as residents or tenants, or in a location facing an entrance that allows access to the balcony structure from a common area within the building. When performing maintenance such as caring for plants planted in the planting containers 60 or cleaning the drainage ditch 23 and the grit-settling section 24a, workers can open the door 41 and safely descend from the balcony section 10 to the plant-installation section 20. Although not shown, for example, a ladder or stairs may be attached to the exterior wall hanging wall section 30.

[0031] The drainage path 50 is connected to the island portion 24b and communicates with the water collection portion 24, and is a drainage pipe that drains unnecessary water from the planting installation portion 20. The drainage path 50 passes through the exterior wall hanging wall portion 30 and passes below the balcony portion 10.

[0032] Fig. 4 is a diagram showing an example of a balcony structure 1 with a planter according to the present disclosure configured for multiple floors. As shown in Fig. 4, a drainage path 50 penetrates the exterior hanging wall portion 30 and passes below the balcony portion 10. The piping of this drainage path 50 can be concealed from view by, for example, a ceiling member 80 shown in Fig. 4. Therefore, the piping of the drainage path 50 can be concealed from view of the balcony portion 10 and from the floor below.

[0033] Additionally, to prevent dead leaves and the like from flowing into the drainage channel 50, a dustproof member 70 for collecting impurities is provided on the planting installation section 20 side of the drainage channel 50. In this embodiment, two dustproof members 70 are provided: a first dustproof member 71 and a second dustproof member 72. The first dustproof member 71 is a small mesh fence arranged around the outer periphery of the sand-settling section 24a. The second dustproof member 72 is a mesh strainer attached directly to the opening of the drainage channel 50. In this embodiment, the mesh of the first dustproof member 71 is coarser than that of the second dustproof member 72. However, the meshes may be the same, or the mesh of the first dustproof member 71 may be finer than that of the second dustproof member 72. The provision of the dustproof member 70 prevents clogging of the drainage channel 50. Furthermore, fallen leaves and the like collect on the dustproof member 70, making cleaning easier.

[0034] The planting container 60 is a container for holding planting soil and planting plants. As described above, the planting container 60 is fixed to the planting installation part 20 by the planting container fixing part 22. The planting container 60 may have any specific form, and examples include a planting pot, a planting box, and a planting basket. The planting container 60 of this embodiment uses a mesh-like planting basket called a gabion combined with nonwoven fabric.

[0035] As described above, the balcony structure 1 with planter installation sections according to the first embodiment can achieve the following excellent effects.

[0036] First, the drainage path 50 penetrates the exterior wall hanging wall portion 30 and passes under the balcony portion 10, so that drainage downspouts (not shown) etc. are not visible from the outside, allowing for a neat appearance.

[0037] Furthermore, by providing the movement restriction section 40, there is no direct line of movement from the indoor side to the plant installation section 20 via the balcony section 10. This significantly reduces the risk of people (especially young children) stepping onto the balcony using plants or other items as a stepping stone to climb over the balcony fence railing and fall, as was the case in the past, and provides a high level of safety.

[0038] Furthermore, because the floor 21 of the planting installation section 20 is appropriately lower than the floor of the balcony section 10, and people who go out onto the balcony section 10 can approach the movement restriction section 40 (fence), a wide view from the balcony section 10 is ensured (see Figure 4). Furthermore, natural objects (plants planted in planting containers 60) are included at the bottom of the view field, creating a view that combines both the view and natural objects. Furthermore, since the plants are unlikely to block light, sufficient light can enter the balcony section 10. Furthermore, because the drainage ditch 23 and the water collection section 24 are located adjacent to the exterior wall hanging wall section 30, the drainage ditch 23 and the water collection section 24 are usually not visible even when approaching the movement restriction section 40 (fence). However, if maintenance is required, the condition of the floor 21 can be easily confirmed.

[0039] Furthermore, because the planting containers 60 are positioned close to the exterior of the building and the floor 21 of the planting installation section 20 is low, it is possible to realize a structure in which the plants planted in the planting containers 60 appear to be approaching the field of vision of someone looking up at the building from outside, and the plants planted in the planting containers 60 appear to cover the building's wall surface with a certain vertical spread. This allows people inside and outside the building to enjoy a sense of symbiosis between the building and nature.

[0040] Furthermore, a lockable door 41 is provided in the movement restriction section 40, allowing maintenance personnel to access the planting installation section 20 through this door. This eliminates the need for aerial work platforms or gondolas, which were previously required for maintaining the plants. As a result, maintenance costs and effort can be reduced. Also, since there is no need to move or remove anything on the balcony when maintaining the plants, the usability of the balcony can be diversified and the degree of freedom can be increased.

[0041] Furthermore, a drainage path for rainwater and the like is provided on the floor 21 of the planting area 20 as a "dedicated drainage route for the planting area," and dustproof members 70 are placed to collect impurities. This prevents the drainage from the planting area from becoming clogged with impurities such as soil particles, dead leaves, and aged plant fibers.

[0042] (Second embodiment) Figure 5 is a cross-sectional view of a balcony structure 1B with a plant-setting section of the second embodiment, similar to Figure 2 of the first embodiment. The balcony structure 1B with a plant-setting section of the second embodiment has the same configuration as the first embodiment, except that the balcony section 10B does not have a configuration equivalent to the parapet 11 in the first embodiment. Therefore, parts that perform the same functions as in the first embodiment described above are given the same reference numerals, and duplicate explanations will be omitted where appropriate.

[0043] The balcony section 10B of the second embodiment does not have a structure equivalent to the parapet 11 of the first embodiment. Correspondingly, the floor of the balcony section 10B is sloped so that the plant installation section 20 side is lower. Therefore, rainwater and the like in the balcony section 10 flows down the exterior wall hanging wall section 30 into the drainage groove 23 and the water collection section 24. Then, the water is drained by the drainage path 50.

[0044] As described above, in the second embodiment, the parapet is omitted, and rainwater received by the balcony section 10B can flow down onto the floor surface 21 of the plant installation section 20, allowing the rainwater to be concentrated in the drainage channel 50, resulting in a rational design. Furthermore, since the parapet is completely omitted, the risk of children using the parapet as a stepping stone and falling is essentially eliminated. Note that the same measures as in the first embodiment are taken to deal with impurities such as soil particles, dead leaves, and aged plant fibers that get mixed into the drainage water generated by the plants.

[0045] Furthermore, all rainwater received by the balcony section 10B naturally flows down onto the floor surface 21 of the plant installation section 20 by gravity, so that the balcony can be effectively prevented from being flooded even when there is a large amount of precipitation per hour.

[0046] Furthermore, rainwater received by the balcony section 10B flows down reliably onto the floor surface 21 of the planting installation section 20, so that rainwater does not stagnate or flood during rainfall, the balcony section 10B can be washed and drained, impurities etc. are less likely to accumulate on the balcony surface, and the balcony is less likely to become dirty.

[0047] The present disclosure is not limited to the above-described embodiments, and various modifications and variations are possible, and these are also within the scope of the present disclosure. [Explanation of symbols]
