Description

[Technical Field]

[0001] The present invention relates to an architectural structure and a construction method, and more particularly to an architectural structure with underfloor storage that can be suitably used in condominiums, apartments, and other multi-family housing and row houses, and a construction method thereof. [Background technology]

[0002] Apartment buildings and other shared housing are common residences for many people, including students and those working away from home. In other words, although apartment buildings have a smaller floor area than the average, they still provide various functions and living space necessary for daily life.

[0003] As a way to utilize space in apartment buildings, a technology has been disclosed that provides storage space under the floor of living areas (Non-Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3110707 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] The prior art discloses technology related to building structures with storage space under the floor of living areas. Such prior art is useful in expanding storage space in buildings with relatively small floor space, such as rental apartments. However, the inventors felt that the prior art had issues that made it less than convenient. In other words, in the prior art, access to the storage space was via a doorway on the side of the storage space and a drawer opening on the floor of the living room, meaning access was from the side and from above. This meant that there were issues with limiting the utilization of the storage space. Furthermore, although the storage space could be accessed from a window, it was accessed from outside, so it was difficult to say that it was particularly convenient.

[0006] In addition, there is also the issue of changing times. In other words, in recent years, working from home has become more popular, and even rental apartments are now required to have multiple functions in addition to the living area. Therefore, even if the exclusive area is limited, there is a demand for technology that can fully utilize this and separate the functions.

[0007] Against the background of the above circumstances, the objective of this invention is to provide an architectural structure that has storage space under the floor of the living area, while achieving functional separation by utilizing the storage space and expanding the usable area. [Means for solving the problem]

Embodiments for Carrying out the Invention

[0015] The present invention will be described.

[0016] <<I. General Outline of the Invention>> The underfloor storage type building structure of the present invention is an underfloor storage type building structure that comprises a living area with underfloor storage, a first ascending staircase for accessing the living area, an access section for accessing the underfloor storage, and a descending staircase for accessing the living area and connected to a loft, wherein the first ascending staircase is connected to the entrance, an access section for accessing the underfloor storage is provided near the first ascending staircase, a toilet and bathroom are provided below the loft, and the lowest part of the first ascending staircase is at the same height as the floor surface of the underfloor storage. As a result, in the under-floor storage type building structure, it is possible to enhance the accessibility to the under-floor storage while achieving a compact structure. In particular, by applying the under-floor storage type building structure to a structure with a limited floor area such as a rental apartment, it is possible to effectively utilize the floor area. In addition, the access section is located near the first ascending staircase, which makes it possible to increase accessibility to the storage space and improve convenience. The under-floor storage type building structure of the present invention is provided as a structural building provided indoors in a condominium such as an apartment or a tenement house or a row house. That is, it is used as a technology that can be generally applied by expanding the usable area and standardizing it under a limited floor area.

[0017] In the present invention, the underfloor storage type building structure comprises a living room, a first ascending staircase, a loft, and a descending staircase. In the present invention, going up and down the stairs is defined as the direction to reach the living room area. That is, the stairs going up to reach the living room area are defined as the upward stairs, and the stairs going down to reach the living room area are defined as the downward stairs.

[0018] The living room area is a part that functions as a living room in the under-floor storage type building structure, and a storage part is provided under the floor. In addition, a side wall part in the storage part is provided with an access part for accessing the under-floor storage near the upward stairs. The living room area does not particularly need to be limited as long as it has these configurations, and can have various shapes or configurations. The living space typically has a rectangular shape with the main part expanding into a rectangular shape, as shown in Figures 6 and 8, and is configured with a rectangular parallelepiped underfloor storage area underneath the floor. However, the living space or storage area does not need to be limited to these shapes, and can be of various shapes and sizes. The access section can typically be configured as an openable door (openable door, door section) provided on the side wall of the underfloor storage, as shown in Figure 7. However, it is not necessary to be limited to such a configuration, and it may also be configured as an open entrance / exit section (open entrance / exit section) without a door. The access section is located near the first ascending staircase. In the present invention, "located near" means located without being separated from the ascending staircase. As a guideline for such arrangement, the distance between the stairs and the access area can be 10 to 300 cm, preferably 10 to 280 cm, more preferably 10 to 260 cm, and most preferably 10 to 240 cm.

[0019] The ascending staircase is a staircase for accessing the living area, and by making it possible to secure space for an access section nearby, it facilitates the design of the access section and improves the convenience of access to the underfloor storage. As long as the ascending staircase has these features, it does not need to be particularly limited and can be of various shapes and configurations. The ascending staircase may be provided as a direct staircase (a staircase that allows direct access to the desired location) at the end of the living area, typically as shown in Figure 4 or Figure 6. By providing a direct staircase, the underfloor storage type architectural structure of the present invention can be applied even in a narrow space, and it also has the effect of reducing costs.

[0020] In the underfloor storage type building structure of the present invention, it is preferable that at least the lowest part of the first ascending staircase is at the same height as the floor surface of the underfloor storage. This aligns the height of the lowest part of the first ascending staircase with the height of the floor of the storage space, so that they are installed on essentially the same plane, which has the effect of improving the robustness of the underfloor storage type building structure of the present invention. In addition, it has the effect of making it easier to design building structures and reducing costs as a standardized technology. In addition, in this invention, "the height of the lowest part and the floor surface of the underfloor storage are aligned" is defined to mean that they are aligned within a reasonable range as an architectural structure, in other words, it means that as an underfloor storage type architectural structure, they are provided on essentially the same plane, and is defined as being able to tolerate some degree of deviation.

[0021] It is preferable that the first staircase be connected to the entrance hall. This provides the necessary components for an apartment building, and has the effect of improving design efficiency and standardizing the technology when using the underfloor storage type architectural structure of the present invention. Typically, the entrance hall is configured to be directly visible from the staircase, as shown in Figure 5, but it is not limited to this configuration. In other words, the staircase and the entrance hall can be configured to exist in a directly or indirectly continuous space. For example, the space between the staircase and the entrance hall can be configured to be directly visible, or indirectly visible by providing a door or the like. Furthermore, even if the staircase or the entrance hall cannot be seen from the other, it is acceptable to move between them as if they were a continuous space.

[0022] In the present invention, it is further preferable that the living area is provided with a descending staircase that is connected to the loft, which makes it possible to use the living area as a room or space for a second (or third) purpose different from the living area, thereby improving the value of the underfloor storage type architectural structure of the present invention. The loft and descending staircase may typically be configured as shown in Figures 6 and 7. In other words, a descending staircase may be provided on the opposite side of the second ascending staircase connected to the small room, and a loft may be provided beyond that in a position parallel to the living area. By providing a toilet and a unit bath below the loft, the apartment can be equipped with the minimum necessary components. In this case, the space below the descending stairs (the space below the descending stairs) can be configured as a toilet. Since the ceiling in the space below the descending stairs has the shape of a staircase, it can also be configured as a toilet, a washroom, a hallway, a closet, etc. Furthermore, the descending stairs are configured so that they are aligned with the wall on the living room side of the loft (they do not protrude from the wall on the living room side), as shown in Figures 6 to 9.

[0023] In the present invention, it is preferable that the loft is provided with a fall prevention facility capable of preventing falling into the living room. Thereby, it becomes possible to prevent the fall of people and objects from the loft, and it has the effect of improving the safety of the underfloor storage type building structure. In addition, the fall prevention facility has the effect of serving as a blind for blocking between the loft and the living room. The fall prevention facility does not particularly need to be limited as long as it can prevent falling, and it may be provided as a facility that can be integrally formed with either or both of the floor or ceiling of the loft. Regarding the fall prevention facility, preferably, it can be configured such that both the ceiling and the loft floor surface are integrally formed and cannot be separated. Thereby, it has the effect of improving the robustness as an underfloor storage type building structure. Such a fall prevention facility can be configured as a handrail, wall, bookshelf, closet, etc., and preferably can be configured as a bookshelf.

[0024] <<II. Embodiment>> The present invention will be described with reference to the drawings.

Further, a first access part 4 and a second access part 4' are provided near each ascending staircase, and it is possible to access a storage part (not shown) provided under the floor from these access parts. In FIG. 1, the side of the first ascending staircase 3 (upper side in FIG. 1) is defined as the back side, and the side of the second ascending staircase 3' (lower side in FIG. 1) is defined as the front side, and the same will be described in the following drawings. Such an underfloor storage type building structure can be represented as the design drawing shown in FIG. 9. In FIG. 9, the gray part means that the loft overlaps, and the surrounding water part below it is shown.

[0026] Figure 2 is a schematic representation of an underfloor storage type building structure, viewed from the front (front view). Below the living area 2, there is a storage area 5 formed with a certain amount of space.

[0027] Figure 3 shows a schematic view (plan view) of an underfloor storage type building structure with a loft and small rooms. A small room 6 is provided next to the second ascending staircase 3', which can be used as a study space, etc. In addition, a descending staircase 8 is provided on the opposite side of the second ascending staircase 3'. By ascending this descending staircase 8 from the living room 2 side, one can reach the loft 7.

[0028] Figure 4 is another example of a schematic view (plan view) of an underfloor storage type building structure. In each case, the first and second staircases are shown positioned on either side of the living room. Similarly, the access points (first and second access points) are also positioned on either side of the living room. The living room functions as a living room or Western-style room.

[0029] Figure 5 is a perspective view of an apartment building that uses underfloor storage architectural structures, seen from the entrance side. Looking from the entrance, there is a first staircase on the left side that can be used to go up to the living area. There is also a staircase (not shown) at the back of the living area that can be used to go up to the loft.

[0030] Figure 6 is a cross-sectional view of an apartment building that uses underfloor storage type architectural structures, viewed from the front, Figure 7 is a view of the same architectural structure from a small room, and Figure 8 is a view of the same architectural structure from the front side (front) of the living area.

[0031] There is an underfloor storage area under the living area, where clothes can be seen being stored. There are also doors at the front and back for access.

[0032] On the right side of the living area, a staircase leads to a small room equipped with a desk as a study space. Next to the desk in the study space, there is also a door that provides access to the underfloor storage.

[0033] On the left side of the living area, a descending staircase leads to the loft, which is equipped with a bed and furniture and can be used as a bedroom with easy access from the living area.

[0034] A bathroom and toilet are located below the loft. In other words, by raising the floor of the living area with underfloor storage and deliberately installing a staircase on the left side of the living area to create a loft, it is possible to secure a certain level of height, making it possible to install a bathroom and toilet.
