Description

[Technical field]

[0001] The present invention relates to apartment buildings. [Background technology]

[0002] In apartment buildings, balconies are generally provided outside the residences. Balconies are often provided along the exterior walls of buildings, but examples of balconies provided inside buildings, such as that disclosed in Patent Document 1, are also known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2023-3600 Summary of the Invention [Problem to be solved by the invention]

[0004] Regardless of whether a balcony is installed along the exterior wall of a building or inside the building, it functions as an escape route. For this reason, balconies in apartment buildings are considered shared facilities. However, because they are shared facilities, residents can only use them for limited purposes, such as drying clothes or installing outdoor air conditioners.

[0005] The present invention aims to provide an apartment building equipped with a balcony that can be used for various purposes. [Means for solving the problem]

[0006] The apartment building of the present invention has a plurality of dwelling units, an exterior wall, and an exterior balcony adjacent to at least one of the dwelling units and provided on the outside of the exterior wall, and the at least one dwelling unit has an interior balcony provided on the inside of the exterior wall. Effect of the Invention

[0007] According to the present invention, it is possible to provide an apartment building equipped with a balcony that can be used for a variety of purposes. [Brief description of the drawings]

[0008] [Figure 1] 1 is a plan view of an apartment building according to one embodiment of the present invention. [Diagram 2] This is an enlarged view of parts A and B in Figure 1 (plan view of the dwelling unit). [Diagram 3] This is an enlarged view of part C in Figure 2(a) (partial plan view of the dwelling unit). [Figure 4] 4A-4A and 4B-4B are cross-sectional views of the dwelling unit in FIG. 3. [Diagram 5] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An embodiment of an apartment house 1 of the present invention will be described with reference to the drawings. The apartment house 1 is preferably two or more stories, but the number of stories is not limited as long as it has an external balcony and an internal balcony, which will be described later. FIG. 1 is a plan view of the floors above the ground floor of an apartment house 1 according to one embodiment of the present invention. The apartment house 1 is a slab-shaped house, and multiple dwelling units H1 to H12 (sometimes referred to as dwelling unit H when there is no need to distinguish between them) are arranged in a row along its long side. Each dwelling unit H is separated by an exterior wall 2 and a partition wall 34 between the dwelling units. Shared facilities such as a shared corridor 31, stairs 32, and elevator 33 are arranged along one of the long sides of the apartment house 1.

[0010] A balcony is arranged along the other side of the rectangle. This balcony is a common balcony also found in conventional apartment buildings, and is referred to as an exterior balcony B1 in this specification. The exterior balcony B1 is provided outside the dwelling unit H, that is, on the outside of the exterior wall 2 of the apartment building 1, and is an outdoor facility that faces the outside air, although the exterior balcony B1 on the upper floor serves as a canopy. The exterior balcony B1 is separated by partition walls 24 for each dwelling unit H, and can be used as an escape route by breaking the partition walls 24 in the event of a fire. The exterior balcony B1 may be used as an installation space for an air conditioner's outdoor unit or a clothes dryer. The exterior balcony B1 does not have to be provided adjacent to all dwelling units H. For example, in the case of a ground floor where the installation of the exterior balcony B1 as an escape route is not necessary, the exterior balcony B1 can be omitted. In other words, the exterior balcony B1 only needs to be provided adjacent to at least one dwelling unit H of the apartment building 1.

[0011] Here, the problems of a conventional balcony (external balcony B1 in this embodiment) will be described. Generally, a balcony is not a private area but a common area, and is arranged on the outside of the exterior wall of a building because it also serves as an evacuation route. The original purpose of a balcony is an evacuation route, and it is not recommended to use it for personal purposes such as placing the owner's or resident's belongings. It is also not desirable to let children play on the balcony alone because there is a risk of falling. In particular, in high-rise tower apartments, the use of balconies as a clothesline is restricted, and there are few opportunities to use balconies on a daily basis, so balconies are often installed only to ensure an evacuation route. Since balconies are installed outside the dwelling unit, they cannot be air-conditioned, and it is difficult to achieve the same level of comfort as the living / dining / kitchen area. It is often difficult to use a balcony depending on the season and weather. Since balconies are adjacent to the balconies of neighboring units, consideration must be given to noise, etc. For the above reasons, although balconies usually face the living / dining / kitchen area, it is difficult to use them together with the living / dining / kitchen area. In particular, in the middle units of slab houses (units sandwiched between other units on both sides; units H2 to H11 in Figure 1), the balcony space is limited, making it difficult to improve convenience. In the gable units (units separated on one side by an exterior wall and adjacent to other units on the other side; units H1 and H12 in Figure 1), a roof balcony B3 that can be used in the same way as a private area is sometimes installed, as shown in Figure 1, but the risk of falling and comfort are the same as for the middle units.

[0012] In this embodiment, at least one of the dwelling units H (dwelling units H2, H3, H7, H8, H11) adjacent to the exterior balcony B1 of the apartment house 1 has an interior balcony B2 provided inside the exterior wall 2. As described later, it is preferable that the interior balcony B2 be an option at the time of purchase, so in the apartment house 1 of this embodiment, the dwelling units H2, H3, H7, H8, H11 equipped with the interior balcony B2 are mixed with the dwelling units H1, H4 to H6, H9, H10, H12 that do not have the exterior balcony B1. The area indicated by the diagonal lines in FIG. 1 indicates the interior balcony B2, and the area indicated by the dashed line indicates the area where the interior balcony B2 can be installed but is not installed. In other words, all of the dwelling units H1 to H12 adjacent to the exterior balcony B1 of the apartment house 1 have an area 3 that can be used as the interior balcony B2. Instead of making it an option at the time of purchase, it is also possible to provide internal balconies B2 in all dwelling units H1-H12 that are adjacent to external balconies B1. It is preferable to provide internal balconies B2 in the middle dwelling units H2-H11, but it is also possible to provide them in the gable dwelling units H1 and H12. Although not shown in the figures, it is also possible to provide internal balconies B2 in dwelling units that are not adjacent to external balconies B1 (for example, dwelling units on the ground floor).

[0013] FIG. 2(a) is an enlarged view of part A in FIG. 1, showing a plan view of the dwelling unit H5. FIG. 2(b) is an enlarged view of part B in FIG. 1, showing plan views of the dwelling units H7 and H8. The dwelling unit H5 does not have an internal balcony B2, while the dwelling units H7 and H8 have an internal balcony B2. FIG. 3 is an enlarged view of part C in FIG. 2(b), showing the living / dining / kitchen area B1, the external balcony B1, and the internal balcony B2 in more detail. Each dwelling unit H basically has the same floor plan, but adjacent dwelling units H (for example, dwelling units H7 and H8) have a mirror arrangement. Each dwelling unit H is equipped with a living / dining / kitchen area 7, three bedrooms 4 to 6, and a toilet / washroom / bathroom area 7. The living / dining / kitchen area is a concept that includes both a separate kitchen and a kitchen (a so-called living / dining / kitchen / living / dining / kitchen), and the living / dining / kitchen area in this embodiment is the living / dining / kitchen area. In the dwelling unit H5, the area 3 is used as part of the living / dining / kitchen area. An external balcony B1 is provided facing the living / dining / kitchen area of ​​each dwelling unit H. The exterior balcony B1 is adjacent to the living / dining / kitchen area through a first sash 8 and can be accessed directly from the living / dining / kitchen area. The interior balcony B2 is adjacent to the exterior balcony B1 through a second sash 9 and is adjacent to the living / dining / kitchen area through a third sash 10.

[0014] Fig. 4(a) is a cross-sectional view taken along line 4A-4A in Fig. 3(a), and Fig. 4(b) is a cross-sectional view taken along line 4B-4B in Fig. 3(a). As shown in Fig. 4(a), in the living / dining / kitchen area, a base panel 35 supported by columns 12 is placed on the floor slab 11, and floor members 13 are placed on the base panel 35, with the upper surface of the floor members 13 forming the floor surface 14 of the living / dining / kitchen area. In the interior balcony B2, a sloped layer 15 is placed on the floor slab 11, and a deck 17 supported by columns 16 is placed on the sloped layer 15, with the upper surface of the deck 17 forming the floor surface 18 of the interior balcony B2.

[0015] The floor surface 18 of the internal balcony B2 is preferably substantially flush with the floor surface 14 of the living / dining / kitchen area. Substantially flush means that the step between the floor surface 18 and the floor surface 14 is zero or at most 2 cm. A flat sash with a small step is preferably used as the third sash 10 between the internal balcony B2 and the living / dining / kitchen area. The third sash 10 is preferably a triple sash or other sash with a large open area when open. The internal balcony B2 is installed indoors as part of the dwelling unit H and can be air-conditioned, so that it can ensure the same comfort and privacy as the living / dining / kitchen area. Furthermore, since an escape route is provided by the external balcony B1 and the internal balcony B2 does not need to function as an escape route, it can be used to store and store the belongings of the owner or resident. For these reasons, the internal balcony B2 can be used integrally with the living / dining / kitchen area.

[0016] The floor surface 18 of the internal balcony B2 is one step higher than the floor surface 19 of the external balcony B1. When the second sash 9 is opened, the internal balcony B2 becomes one with the external balcony B1, making it possible to take in outside air. The second sash 9 and the third sash 10 form a kind of double sash, which is also preferable from the standpoint of heat retention of the living, dining, and kitchen area.

[0017] The use of the internal balcony B2 is not limited in any way, and the owner or resident can freely decide it as long as it does not violate the management regulations of the apartment building 1. The internal balcony B2 allows for uses that are difficult to realize in conventional apartment buildings. The internal balcony B2 can be used in the same way as a garden, veranda, courtyard, or rooftop of a detached house, and can be used, for example, as an area for installing a vinyl pool, an area for installing a flower bed or a vegetable garden, or an eating and drinking area for barbecues. There is no step between the internal balcony B2 and the living, dining, and kitchen area, and there is no need to change shoes, so it is easy to move between them. It can be used in a comfortable environment all year round, regardless of the season or weather (and even the time of day). It can be used as a safe playground for children, as it is easy for parents to keep an eye on it and there is no risk of falling. It can also be used for purposes where pollution and dust are likely to occur, such as a workshop or studio. It can also be used as a large storage space. It can also be used as a drying space, and by opening the second sash 9 between the internal balcony B2 and the external balcony B1, it is possible to dry clothes by introducing outside air regardless of the weather. When eating and drinking such as for barbecues or when using the balcony as a workshop, natural ventilation is possible by opening the second sash 9 between the balcony and the external balcony B1, so smoke, odors, dust, etc. are less likely to build up in the balcony B2. In this way, the balcony B2 can be used in a manner that would be difficult with the living / dining / kitchen area and the external balcony B1, and can be used together with the balcony B1. Since the balcony B2 is part of the dwelling unit H, the area of ​​the exclusive area will not decrease due to the balcony B2. Therefore, it is unlikely that the sales price of the entire apartment building will decrease. Even if the balcony B2 is treated as a common area like the external balcony B1, it is possible to set the exclusive use rights of the condominium owners for the balcony B2 and treat it the same as an exclusive area. In this case, it is unlikely that the sales price of the entire apartment building will decrease.

[0018] In order to enable such uses of the internal balcony B2, the internal balcony B2 has several features. First, as described above, the internal balcony B2 preferably has a deck 17 that constitutes the floor surface 18 of the internal balcony B2. The deck 17 is installed on the floor slab 11 of the apartment building 1 via the inclined layer 15 and the support 16. The deck 17 may be integrated with the support 16. FIG. 5 shows a partial plan view of the deck 17. The deck 17 is made up of a plurality of boards 20 arranged in parallel at intervals, and is configured in the same manner as a slatted board. The deck 17 is not limited to the shape of a slatted board, but has a gap 21 that penetrates from the front surface to the back surface, and drains water through this gap 21 when the pool is used or when watering. The gap 21 does not need to penetrate vertically, and may be bent in a three-dimensional shape. It is preferable that the deck 17 is detachable from the support 16 so that it can be removed for cleaning.

[0019] As shown in FIG. 4(a), the installation surface 22 (upper surface of the inclined layer 15) of the deck 17 is preferably inclined downward with respect to the floor surface 14 of the living / dining / kitchen area in order to provide drainage. This can prevent the drainage water generated in the internal balcony B2 from entering the living / dining / kitchen area. Furthermore, as shown in FIG. 4(b), the installation surface 22 of the deck 17 is preferably inclined downward toward the external balcony B1. That is, as shown by the arrow R in FIG. 3, the floor slab 11 as a whole is preferably inclined downward in an oblique direction from the living / dining / kitchen area to the external balcony B1. This can further prevent water from entering the living / dining / kitchen area. As shown in FIG. 3 and FIG. 4(b), a drain outlet 23 is provided at the lowest position of the installation surface 22. The drain outlet 23 is connected to a vertical drainage pipe 24 that leads to the sewer. As shown in FIG. 4(b), the internal balcony B2 has an opening 25 that communicates with the external balcony B1 between the deck 17 and the installation surface 22 of the deck 17. The opening 25 drains the wastewater that cannot be treated by the drain outlet 23 to the external balcony B1. By these measures, the drainage function can be completed by the internal balcony B2 alone.

[0020] Since the internal balcony B2 may be used for purposes such as a pool, watering, and barbecues, it is preferable that not only the deck 17 but also the installation surface 22 of the deck 17, the wall surface 26 (see Figure 3), and the ceiling surface 27 (see Figure 4) are treated to be heat and water resistant. Furthermore, since these areas are more prone to getting dirty than the living / dining / kitchen area, it is preferable that these areas are finished in a way that makes them less susceptible to dirt. The material of the deck 17 can be wood, resin, etc., as long as it is treated to be heat and water resistant. Flooring material, ceramic, tiles, etc. that have been treated to be heat and water resistant may be installed instead of the deck 17.

[0021] In order to improve the convenience of the internal balcony B2, it is preferable that the internal balcony B2 is further equipped with the following facilities. Since the internal balcony B2 may be used for plant cultivation and barbecues, ventilation must be considered. For this reason, it is preferable that the internal balcony B2 has a ventilation system and a deodorizing system (both not shown) that are completed by the internal balcony B2 alone. This can prevent the spread of odors to neighboring residences and the residence itself. It is also preferable to have a water faucet 28 (see FIG. 3) for convenience of swimming pools and watering. The water faucet 28 is preferably installed near the drain 23 as shown in FIG. 3 so that it can be quickly drained in the event of overflow. Although not shown, in order to foster a sense of unity with the outside of the building, for example, an artificial skylight device (a wall-mounted display device for displaying images such as scenery), a device that reproduces natural sounds (such as the sound of waves, the sound of a stream, and the chirping of birds), and an aroma device (such as the scent of the forest) may be installed.

[0022] If the installation of the internal balcony B2 is made an option at the time of sale, the decision as to whether or not to install the internal balcony B2 will be made after the start of sales of the apartment building 1. Therefore, in order to avoid any influence on the structural design of the building, it is preferable that the wall 29 between the bedroom 4 and the internal balcony B2 is formed by a dry construction method using drywall or an ALC (Autoclaved Lightweight Aerated Concrete) panel. It is preferable that the drywall or ALC panel has the same performance as the exterior wall 2, which increases the independence of the bedroom 4 and the internal balcony B2, and improves the thermal insulation and privacy of the bedroom 4. Since the drywall or ALC panel is a non-load-bearing wall that does not contribute to the structural design of the building, it does not affect the structural design of the building or the application for building confirmation. Furthermore, by adopting such a dry construction method, it is easy to change part of the living / dining / kitchen area to the internal balcony B2 or make the internal balcony B2 a part of the living / dining / kitchen area during renovation. A window 30 may be provided in the wall 29. If there is no internal balcony B2 (see Figure 3(a)), it is difficult to ensure sufficient lighting because the bedroom 4 does not face the outside, but by adding a window 30, it is possible to indirectly let in light from the outside through the internal balcony B2. This makes it possible to create a bedroom 4 that feels open while still maintaining a private space.

[0023] There is no partition between the living / dining / kitchen area and the internal balcony B2, but if one is provided, it can be formed using a dry construction method. It is also possible to separate the living / dining / kitchen area and the internal balcony B2 with, for example, a movable rail-type partition wall instead of a sash. A movable rail-type partition wall can be folded up and stored compactly, further improving the sense of unity between the living / dining / kitchen area and the internal balcony B2. It is also possible to leave a complete opening between the living / dining / kitchen area and the internal balcony B2 and separate it with a movable caster-type partition wall. In this case, the structure between the living / dining / kitchen area and the internal balcony B2 can be made common to all dwelling units H, reducing design and construction costs.

[0024] In order not to affect the facility design of the building, it is preferable to standardize the configuration of the internal balcony B2 and various related facilities regardless of whether the internal balcony B2 is installed or not. Specifically, it is preferable to carry out the following construction in all areas 3 where the internal balcony B2 can be installed. Installation of a sloped layer 15 with a slope Heat and water resistance treatment of the installation surface 22, wall surface 26, and ceiling surface 27 of the deck 17 Installation of the above-mentioned drain outlet 23, drain vertical pipe 24, drain opening 25, ventilation equipment, deodorizing equipment, water pipes connected to the water faucet 28, electrical outlets, through holes for air conditioners, etc. This will make it possible to carry out construction work efficiently after the decision to install Internal Balcony B2 has been made.

[0025] As shown in FIG. 1 and FIG. 2(a), it is preferable that the internal balconies B2 of two adjacent dwelling units H (e.g., dwelling units H7 and H8) are adjacent to each other. As mentioned above, the use of the internal balconies B2 is not limited, but it is also possible to use them in a way that may generate a certain amount of noise, such as barbecues. By having the internal balconies B2 adjacent to each other, noise is less likely to be transmitted to the living / dining / kitchen area of ​​the adjacent dwelling units H, improving convenience. For the same reason, although not shown in the figures, it is also preferable to provide the internal balconies B2 in the same position on the upper and lower floors. Note that the internal balconies B2 do not need to be adjacent to other internal balconies B2, and can be located in the same position in each dwelling unit H. In other words, it is not necessary to have a mirror arrangement for the adjacent dwelling units H.

[0026] Although the present invention has been described above by way of an embodiment, the present invention is not limited to the embodiment. In the embodiment, the internal balcony B2 is disposed adjacent to the external balcony B1, but the position of the external balcony B1 is not limited. For example, either of the bedrooms 5 and 6 on the entrance side can be used as the internal balcony B2. In addition, the type of the apartment house 1 of the present invention is not limited, and it may be a tower type. [Explanation of symbols]
