Description

[Technical Field]

[0001] The present invention relates to a building whose interior is divided into compartments. [Background technology]

[0002] There has long been a demand for low-cost housing by simplifying and simplifying the floor plan design of buildings and by reducing and shortening the time and labor required for design and construction.

[0003] Therefore, Patent Document 1 proposes a house that reduces costs by using a simple floor plan that is symmetrical in all directions, with C-shaped spaces of the same shape and size at the four corners of a rectangle and a cross-shaped free space. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2013-170363 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the house described in Patent Document 1 has spaces of different sizes, uses many interior columns that serve as support materials for the house, and also uses partition walls, so even if one wanted to change the plan design or furniture layout later, there were restrictions placed on it, making it difficult to freely design and change the plan.

[0006] Therefore, the present invention has been made in consideration of the above circumstances, and aims to provide a building with a high degree of freedom in plan design and modification. [Means for solving the problem]

[0007] In order to solve the above problems, the building according to the present invention has a rectangular interior in plan view, and includes load-bearing walls provided at the four outermost corners, four corner sections located at the four corners of the interior of the building with the load-bearing walls as at least one side, a central section located at the center of the interior of the building, four side sections surrounded by the four corner sections and the central section, and four center columns located at the four corners of the central section, and each of the nine sections has one use within the building. The central section and at least two of the four side sections are semi-outdoor spaces, and the side sections of the semi-outdoor spaces are buildings connected to the outside of the premises.

[0008] Preferably, the bearing walls are arranged in an L-shape in plan view in the building.

[0009] Preferably, each section is a building having the same rectangular shape in plan view and the same area.

[0010] Preferably, the plot is a building that is square in plan view.

[0012] Preferably, one of the side sections, which is a semi-outdoor space, has an opening that is completely open to the outside of the site, and the central section and the other side section, which is also a semi-outdoor space, are buildings that are courtyards.

[0013] Preferably, the building has an outdoor floor with the same shape and area as each section from the other side section to the central section. [Effects of the Invention]

[0014] The building of the present invention is divided into nine sections: four corner sections with load-bearing walls as two sides and a center pillar as one vertex; a central section with a center pillar as four vertices; and four side sections surrounded by the four corner sections and the central section.The nine sections can be used for different purposes within the building, allowing building users or residents to freely design and change the plan.

[0015] In addition, the bearing walls are arranged in an L-shape when viewed from above, so they are symmetrical from left to right and top to bottom at the four corners, ensuring that the strength is not uneven and they can withstand horizontal and torsional forces in a balanced manner.

[0016] Furthermore, the four corner sections, side sections, and central section all have the same rectangular shape and area when viewed from above, which reduces the number of components required for the entire building, thereby reducing costs and improving workability.

[0017] Furthermore, by making the four corner sections, central section, and side sections square in plan view, it is possible to further reduce the number of types of components used throughout the building, thereby reducing costs and improving workability.

[0018] In addition, the central section and any two side sections are semi-outdoor spaces, and the side sections of the semi-outdoor space are connected to the outside of the site, so it is possible to create a flow line that allows people to pass through from the side sections through the central section. In addition, the semi-outdoor space can separate the section surrounded by the outdoor space section from the other sections.

[0019] In addition, one of the side sections, which is a semi-outdoor space, has an entrance area and an opening that is completely open to the outside of the site, while the central section and the other side section, which is also a semi-outdoor space, are courtyards, allowing people inside the building to feel a sense of openness and enjoy the view of the courtyard.

[0020] In addition, by having an outdoor floor extending from the other side compartment to the central compartment, it is possible to go from the four corner compartments surrounded by a semi-outdoor space to the two compartments facing the outdoor floor via the outdoor floor, and by making it the same shape and area as the compartments, the length and width of the outdoor floor can be easily grasped.

[Figure 2] 1 is a schematic plan view of the second floor of a building according to the present invention. [Figure 3] 1 is a schematic front view of a building according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0022] The present invention will be described in detail below with reference to the drawings. Note that the embodiments and examples of the present invention are merely one aspect of the present invention and can be modified without departing from the spirit of the present invention. In this specification, the interior of building 1 includes not only indoor spaces but also semi-outdoor spaces such as courtyards and verandas.

[0023] [About the embodiment of Building 1] The building 1 according to the present invention is a building in which the interior of the building 1 is divided into sections for different uses. The building 1 is rectangular in plan view, and has L-shaped bearing walls 2 at the four corners of the outermost periphery, and four center pillars 3 at approximately the center of the interior of the building 1.

[0024] (About shear wall 2) The shear walls 2 are the framework of the building 1, located at the four outermost corners. At least one shear wall 2 is located at each of the four corners of the building 1, forming the four corners. In this embodiment, the shear walls 2 are arranged in an L-shape in plan view, so that the shear walls 2 are approximately perpendicular to each other at the four corners. If the building 1 is a wooden house, the shear walls 2 use braces or cross-braces (not shown in the drawings). The braces or cross-braces are reinforcing materials that run diagonally within a rectangular frame consisting of columns, beams, foundations, etc. The use of the braces or cross-braces maintains horizontal strength and prevents deformation of the building during earthquakes and typhoons. Furthermore, the L-shaped shear walls 2 are arranged symmetrically at the four corners of the building 1, ensuring balanced resistance to horizontal and torsional forces without imbalance in strength. When braces are provided in the bearing walls 2, the diagonal directions of the braces are set to be different directions on each side of the building 1. In addition, in this embodiment, two bearing walls 2 are arranged at the four corners to form an L-shape in plan view, but an L-shaped wall may also be used in which one wall is a bearing wall 2 and the other is a non-bearing wall, and it is sufficient that at least one bearing wall 2 is provided at each of the four corners inside the building 1.

[0025] (Regarding center pillar 3) The center pillars 3 are the skeleton of the building 1, and four of them are provided at equal intervals in approximately the center of the interior of the building. In this embodiment, the center pillars 3 are tubular pillars, but they may be through pillars if necessary.

[0026] By placing the framework of building 1 at the four outermost corners and approximately in the center of the interior of building 1, there is no need to provide support materials inside building 1, making it possible to create a large space inside building 1. By creating a large space inside building 1, it is possible to increase the degree of freedom in renovations and furniture layout.

[0027] (About the plot) As shown in Fig. 1, the layout of the first floor of building 1 will be described. The interior of the building is divided into nine rectangular sections, each measuring 3 vertically and 3 horizontally. As shown in Fig. 1, in the first floor plan of building 1 according to this embodiment, the sections are numbered 1st section a to 9th section i, starting from the top left.

[0028] The sections have four corner sections S1, with two sides of the load-bearing wall 2 and one center column 3 as vertices, a central section S2 surrounded by the center column 3, and side sections S3 surrounded by the four corner sections S1 and the central section S2. That is, the four corner sections S1 are the first section a, the third section c, the seventh section g, and the ninth section i, the central section S2 is the fifth section e, and the side sections S3 are the second section b, the fourth section d, the sixth section f, and the eighth section h. The first section a to the ninth section i all have the same shape and area.

[0029] The shape of the plot is rectangular, and in this embodiment, it is a square with each side measuring 3 to 8 meters. Therefore, as shown in Figure 1, the lengths of the two sides of the bearing wall 2 are the same, and the length L1 of a perpendicular line drawn from the center column 3 to the neighboring outermost wall is the same as the length L2 of one side of the bearing wall 2 parallel to the perpendicular line. The shape of the plot does not have to be square, but may be rectangular. By making it rectangular, it is possible to increase the response capacity regardless of the shape of the site.

[0030] By making each compartment the same shape and area, the number of different parts can be reduced by preparing sashes and boards of the same shape for each compartment, which reduces costs. In addition, work can be simplified and standardized in design and on-site, improving workability, shortening construction time and saving effort. It also increases the degree of freedom in design and planning.

[0031] Furthermore, by using the same materials, it is possible to align the thinness of the lines and the position of the lighting, etc., creating a sense of regularity. Creating a sense of regularity gives a clean impression to those inside Building 1, enhancing the sense of unity inside Building 1, and as a result, improving the design quality of the interior of Building 1.

[0032] Furthermore, for the users or residents of Building 1, knowing the length and width of a section makes it easier to decide the layout of furniture and objects to be placed inside Building 1 and to plan renovations. In particular, if the section is square, the users or residents of Building 1 can easily understand the length and width by simply knowing the length of one side.

[0033] Each section has one use within the building 1, such as a kitchen or bathroom. Each section may have one use, or sections with the same use may exist in succession both horizontally and vertically.

[0034] The four corner sections S1 are sections adjacent to the L-shaped bearing walls 2 provided on the outermost periphery of the building 1, and have the bearing walls 2 as at least one side. Since the exterior walls on the outside of the site are the bearing walls 2, no openings such as windows or doors leading to the outside of the site are provided. The four corner sections S1 are sections at the corners of the building 1, and face the side sections S3. In this embodiment, bearing walls 2 arranged in an L-shape when viewed from above are used, and therefore the bearing walls 2 form two sides.

[0035] The central section S2 is the middle section of the building 1 surrounded by four central pillars 3 and faces the side section S3.

[0036] The side section S3 is a section surrounded by the central section S2 and the four corner sections S1 on the left, right, front, and back. Therefore, the side section S3 faces both the corner sections S1 and the central section S2. The side section S3 may have an opening 4 on the entire exterior side of the premises, or it may have a bay window, sliding window, door, etc. on a portion of the exterior side of the premises. By providing the opening 4 on the entire exterior side, people inside the building 1 can easily recognize the division between the corner sections S1 and the side section S3, with the opening 4 in the side section S3 and the wall surface of the corner section S1 as the boundary.

[0037] The side section S3 may have openings 4 on all sides that lead to the outside of the site. The four corner sections S1 do not have openings 4 that lead to the outside of the site, so as shown in Figure 3, when the building 1 is viewed from the outside of the site, the eighth section h appears as an empty space in the building 1. Also, it is not necessary to provide openings 4 on the outside of the site of all side sections S3.

[0038] By surrounding the side section S3 and central section S2 with the four corner sections S1 that do not have openings 4, the side section S3 and central section S2 can be made into private spaces, preventing excessive visibility from others even when buildings are closely spaced or facing a road. On the other hand, by providing openings 4 that connect to the outside of the site on all or part of the 8th section h, which is side section S3, it is possible to have a connection to the interior of building 1 even from outside the site, and building 1 is no longer closed off from the streetscape.

[0039] Although the sections of the building 1 according to this embodiment are square, they may be rectangular with different length and width. When the sections are rectangular, it is desirable that the length and width of the building 1 and the length and width of the sections are aligned.

[0040] [About the Examples] An embodiment (design method) of a building 1 according to the present invention will be described. The users or residents of Building 1 can determine the appropriate use for each section.

[0041] In this embodiment, when the building 1 is a residence, the central section S2 and two of the four side sections S3 are semi-outdoor spaces. A semi-outdoor space refers to an outdoor space within the building's premises. The two side sections S3, which are semi-outdoor spaces, are connected to the outside of the building's premises. The eighth section h, which is one of the side sections S3 of the semi-outdoor space, has an entrance area 5, and the fourth section d, which is the other side section S3 of the semi-outdoor space, is a courtyard 6 that can be connected to the outside of the premises. A courtyard refers to a garden located within the building's premises.

[0042] (About the first floor) As shown in Figure 1, on the first floor, the first section a is used as the area for water facilities such as the bathroom, toilet, and washroom, the second section b is used as the dining area with the dining table, the third section c is used as the kitchen, the fourth section d and the fifth section e are used as courtyard areas, the sixth section f and the ninth section i are used as living rooms where users or residents can relax, the seventh section g is used as a rental office, and the eighth section h is used as the area with the entrance area 5.

[0043] Since the side section S3 faces both the four corner sections S1 and the central section S2, by providing an entrance section 5 in the side section S3, people entering through the entrance section 5 can access either the four corner sections S1 or the central section S2.

[0044] Section 2 b is used as a dining room. As the dining room faces the courtyard 6, you can enjoy the view of the courtyard 6 while eating. Also, when looking towards the courtyard 6 from the dining room, you can see section 8 h, a semi-outdoor space, through the courtyard 6, giving you a sense of depth. The opening 4 on the outdoor side of section 2 b is a ground-level window, which allows for good ventilation from the courtyard 6 while blocking views from outside.

[0045] Section 8h, which is a side section S3, has an entrance 5, through which one can enter section 9i, which is the living room. Alternatively, one can go from section 8h to section 5e, which is the courtyard 6, or section 7g, which is the rental office. If one passes through section 5e, which is the courtyard 6, one can go to section 4d without removing one's shoes, and then pass through building 1 to exit the premises. In this way, section 4d, section 5e, and section 8h, which are semi-outdoor spaces, also function as traffic lines.

[0046] Section 6 f and section 9 i are used as living rooms. Connecting the living room to the courtyard 6 gives the living room a sense of spaciousness and depth. Also, installing large windows in the living room emphasizes the connection to the outside, creating a visual effect that makes the space appear more spacious than the actual floor plan.

[0047] In this embodiment, the fifth section e, which is the central section S2, and the fourth section d, which is the other side section S3, form the courtyard 6. Just as the fourth section d and the fifth section e are connected to form the courtyard 6, sections with the same purpose may be connected vertically and horizontally.

[0048] Sections 1 a to 3 c, 6 f, and 7 g, which face section 4 d and section 5 e, which are courtyard 6, each have a bay window 7 facing the courtyard 6. By making sections 4 d and 5 e into courtyard 6 and having bay windows 7, the courtyard 6 can be seen from section 2 b, which is the dining area, and section 1 a, which is the bathroom. In addition, lighting and ventilation can be secured from the courtyard 6 into the interior, and even people in sections that do not face the courtyard 6, such as section 1 a and section 9 i, can see the courtyard 6 through the bay windows 7.

[0049] In the courtyard 6, an outdoor floor 8 is provided across the fourth section d and the fifth section e. The outdoor floor 8 bridges the sixth section f with the first section a or the second section b. In this embodiment, the outdoor floor is a wooden deck, but it may also be tiled, brick-finished, or cement-finished.

[0050] The outdoor floor 8 is set up in the courtyard 6 of the outdoor space. The outdoor floor 8 has the same shape and area as one of the sections, and is offset half a grid from the fourth section d towards the fifth section e. By making the outdoor floor 8 the same shape and area as one of the sections, users of the outdoor floor 8 can easily grasp the length and width even when they are not there.

[0051] By shifting the fourth section d toward the fifth section e by half a grid and positioning it between the fourth section d and the fifth section e, the following effects are achieved. (i) It is possible to have courtyards 6 on the left and right sides of the outdoor floor 8. Therefore, by planting in the courtyards 6, it is possible to create a space surrounded by greenery around the outdoor floor 8.

[0052] (ii) Furthermore, if the outdoor floor 8 is a wooden deck, the underside of the wooden deck tends to accumulate moisture and fallen leaves, making it difficult to clean. However, since the outdoor floor 8 faces the left and right courtyards 6 or the 8th section h side of the outdoor floor 8, the underside of the outdoor floor 8 can be cleaned from the left and right courtyards 6 or the 8th section h side, and the underside of the outdoor floor 8 can be kept clean.

[0053] (iii) Furthermore, the outdoor floor 8 is easily ventilated below as wind blows through from the outside of the fourth section d and the eighth section h, which are the side sections S3.

[0054] (iv) The outdoor floor 8 faces the indoors of the first section a, the second section b, and the seventh section g, so that it is possible to go directly from the seventh section g to either the first section a or the second section b by crossing the outdoor floor 8. Conversely, it is also possible to go from the first section a or the second section b to the seventh section g by crossing the outdoor floor 8.

[0055] The semi-outdoor space, which is L-shaped in plan view, separates the indoor space consisting of sections 1 a to 3 c, 6 f, and 9 i from section 7 g, allowing section 7 g to be separated from sections 2 b and 6 f, which include lively living and dining areas.

[0056] Therefore, the seventh section g, which is a corner section S1 surrounded by a semi-outdoor space, can be used as a detached building and can be a section with a tranquil space. In this embodiment, the seventh section g is a rental office. Furthermore, since the seventh section g faces the eighth section h, which includes the entrance area 5, users of the rental office can enter the rental office directly from the entrance area 5 without passing through private spaces such as the living room or dining room. In addition to being a rental office, the seventh section g can also be used as a section with a tranquil space such as a master bedroom or study.

[0057] (About the second floor) Next, we will explain the layout of the second floor using Figure 2. The layout of the second floor also has nine sections formed at the four corners of the building 1 by L-shaped bearing walls 2 and center pillars 3. The second floor is similarly divided into sections from the top left, numbered 10 section j to 18 section r. As with the first floor, each section on the second floor has one use within the building 1.

[0058] Similarly, the second floor has four corner sections S1, each with two sides of the bearing wall 2 and one center column 3 as its vertex; a central section S2 surrounded by the center column 3; and side sections S3 surrounded by the four corner sections S1 and the central section S2. That is, the 10th section j, the 12th section l, the 16th section p, and the 18th section r are the four corner sections S1, the 14th section n is the central section S2, and the 11th section k, the 13th section m, the 15th section o, and the 17th section q are the side sections S3. Sections 10th to 18th are all the same shape and area. Sections 10th to 18th correspond to sections 9th to 18th on the first floor, respectively.

[0059] On the second floor, the 10th section j is the bathroom section, the 11th section k and the 12th section l are the children's room sections, the 13th section m is the half balcony 9 section, the 14th section n is the atrium section of the courtyard 6, the 15th section o is a relaxation space, the 16th section p is the hobby room section, the 17th section q is the balcony section, and the 18th section r is the master bedroom section.

[0060] The children's rooms are located in the 11th section k and the 12th section l, which correspond to the second floor of the 2nd section b and the 3rd section c. By locating the children's rooms in the four corner sections S1, and having load-bearing walls 2 on two sides, it is a private space that is shielded from view from the outside.

[0061] The half balcony 9 is located in the 13th section m, at a position corresponding to the second floor of the 4th section d. The inner half of the half balcony 9 is a semi-outdoor balcony space, and the outer half is an indoor space. As there is no roof over the half balcony 9, light can easily reach the courtyard 6. The view of the courtyard 6 can be enjoyed from the half balcony 9. As the half balcony 9 is located above the left half of the outdoor floor 8, it is possible to create shade on the outdoor floor 8. Therefore, the left half of the outdoor floor 8 can be in the shade, and the right half can be in the sun.

[0062] The relaxation space is located in section 15 o, which corresponds to the second floor of section 6 f. Half of the relaxation space is shared with the living room and an open atrium. The open atrium gives the living room a sense of openness and allows for good ventilation. On the outdoor side of the relaxation space, there is a skylight (opening 4), which allows light to reach the living room. Chairs and sofas have also been installed, allowing people in the living room on the first floor to communicate through the open atrium.

[0063] The hobby room is located in the 16th section p, corresponding to the second floor of the 7th section g. By locating the master bedroom in the four corner sections S1, and having load-bearing walls 2 on two sides, it is a private space that is shielded from view from the outside. Furthermore, since access to the hobby room requires passing through a balcony 10 or semi-balcony 9, it can be a space slightly separated from everyday spaces such as the master bedroom and children's room. The hobby room could be, for example, a studio. Even if sound leaks, it is transmitted via the balcony 10 or semi-balcony 9, preventing it from being transmitted directly to the children's room or master bedroom.

[0064] The balcony 10 is located in the 17th section q, at a position corresponding to the second floor of the 8th section h. The balcony 10 is a semi-outdoor space and has no roof, allowing light to easily reach the courtyard 6. Therefore, in this embodiment, the building 1 is constructed so that the balcony 10 faces south. The view of the courtyard 6 can be enjoyed from the balcony 10.

[0065] The master bedroom is located in the 18th section r, which corresponds to the second floor of the 9th section i. By locating the master bedroom in the corner section S1, and having load-bearing walls 2 on two sides, it is a private space that is shielded from view from the outside.

[0066] The building 1 according to the present invention is suitable for use in residential buildings, particularly detached houses, but may also be used as apartment buildings, condominiums, stores, offices, and facilities. The building 1 according to the present embodiment is a two-story building, but it may also be a single-story building or a building with three or more floors. The building 1 according to the present embodiment is a wooden house, but it may not be wooden (wooden frame), and may be made of reinforced concrete (RC) or steel (S) frame construction.

[0067] [Appendix 1] Appendix 1 states that the interior of the building is rectangular in plan view, with load-bearing walls at each of the four outermost corners, four corner sections located at the four corners of the building with the load-bearing walls as two sides, a central section located in the center of the building, four side sections surrounded by the corner sections and the central section, and four center pillars located at the four corners of the central section, and each of the nine sections has one internal use.

[0068] According to Appendix 1, the building is divided into nine sections: four corner sections with load-bearing walls as two sides and a center pillar as one vertex; a central section with a center pillar as its four vertices; and four side sections surrounded by the four corner sections and the central section.The sections can be used for different purposes within the building, allowing building users or residents to freely design and change the plan.

[0069] [Appendix 2] The building is described in Appendix 1, wherein the bearing walls are arranged to form an L-shape in plan view.

[0070] According to Appendix 2, the bearing walls are arranged so that they are L-shaped when viewed from above, and are arranged symmetrically at the four corners, so that the bearing force is not uneven and can withstand horizontal and torsional forces in a balanced manner.

[0071] [Appendix 3] The plots are buildings described in Appendix 1 or Appendix 2 that are rectangular in plan view and have the same area.

[0072] According to Appendix 3, the plots have the same rectangular shape and area when viewed from above, which reduces the number of components in the entire building, cutting costs and improving construction efficiency.

[0073] [Appendix 4] According to Supplementary Note 4, the shape of the plot is a square in plan view, which is a building described in any one of Supplementary Notes 1 to 3.

[0074] According to Appendix 4, by making the corner sections, central section, and side sections square in plan view, it is possible to further reduce the number of types of components used throughout the building, thereby reducing costs and improving ease of construction.

[0075] [Appendix 5] According to Appendix 5, the central section and at least two of the four side sections are semi-outdoor spaces, and the side sections of the semi-outdoor space are connected to the outdoors, in a building described in any of Appendixes 1 to 4.

[0076] According to Appendix 5, the central section and any two side sections are semi-outdoor spaces, and since the side sections of the semi-outdoor space are connected to the outside of the premises, it is possible to pass through from the side sections through the central section. In addition, the semi-outdoor space can separate the four corner sections surrounded by the semi-outdoor space sections from the other sections.

[0077] [Appendix 6] According to Appendix 6, one of the side compartments, which is a semi-outdoor space, has an opening that is completely open to the outdoors, and the central compartment and the other side compartment, which is also a semi-outdoor space, are courtyards, which is the building described in Appendix 5.

[0078] According to Appendix 6, one of the side compartments, which is a semi-outdoor space, has an entrance area and an opening that is completely open to the outdoors, and the central compartment and the other side compartment, which is also a semi-outdoor space, are made into a courtyard, so that people inside the building can feel a sense of openness.

[0079] [Appendix 7] According to Appendix 7, the building described in Appendix 6 has an outdoor floor of the same shape and area as the other side section extending from the central section to the other side section.

[0080] According to Appendix 7, the other side compartments have outdoor floors of the same shape and area as the compartments extending from the central compartment, so that it is possible to go from the four corner compartments surrounded by a semi-outdoor space to the two compartments facing the outdoor floor via the outdoor floor.
