Summary of the Invention

Problems to be Solved by the Invention

[0004] In the apartment house described in Patent Document 1, since there are other dwelling units on both sides of each dwelling unit, the surfaces facing the outside of the apartment house are limited to the outer surfaces of the apartment house. Therefore, the walls provided with openings for lighting are limited, and the improvement of comfort is restricted. The same problem exists in buildings having rooms where people stay for a long time, such as hospitals and hotels.

[0005] An object of the present invention is to provide a building in which a plurality of compartments are arranged circumferentially around the center of one floor and the walls facing the outside of the building of each compartment can be increased.

Means for Solving the Problems

[0006] The building of the present invention has a plurality of compartments arranged circumferentially around the center of a floor, a plurality of boundary walls separating adjacent compartments, and an outer wall defining the outer boundary of the plurality of compartments. According to one embodiment of the present invention, the outer wall has a plurality of projecting portions and a plurality of retracting portions arranged alternately circumferentially, each of the plurality of projecting portions projecting away from the center opposite each of the plurality of compartments, and each of the plurality of retracting portions retracting toward the center opposite each of the plurality of boundary walls. According to another embodiment of the present invention, the outer wall has a plurality of first portions connected to the plurality of boundary walls, and the two first portions connected to each of the plurality of boundary walls form an angle of less than 180° outside the outer wall. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a building in which multiple sections are arranged circumferentially around the center of a single floor, and the number of walls facing the exterior of the building for each section can be increased. [Brief explanation of the drawing]

[0008] [Figure 1] This is a floor plan of an apartment building according to one embodiment of the present invention. [Figure 2] Figure 1 is a cross-sectional view of the apartment building shown. [Figure 3] This is a conceptual diagram showing the outer wall of this embodiment and comparative example. [Figure 4] This is a floor plan showing an example of the layout of each dwelling unit. [Figure 5] This is a floor plan showing a modified example of an apartment building. [Modes for carrying out the invention]

[0009] Some embodiments of the present invention will be described with reference to the drawings. The following embodiments relate to apartment buildings, but the present invention is not limited to apartment buildings and can also be applied to buildings with multiple sections where people stay for long periods of time (hospital rooms, hotel rooms, etc.), such as hospitals and hotels. Figure 1 is a floor plan of apartment building 1, and Figure 2 is a cross-sectional view of apartment building 1. Figure 1(a) shows a floor plan of a standard floor above the first floor (section AA in Figure 2 as an example), and Figure 1(b) shows a floor plan of the first floor (section BB in Figure 2). Floors above the second floor are basically configured in the same way as the standard floor. Apartment building 1 in this embodiment is a six-story building, but the number of floors in apartment building 1 is not limited. In the following description, the circumferential direction C is the direction along a circle centered on the center FC of a floor, and the radial direction R is the direction along a straight line passing through the center FC of that floor. Unless otherwise specified, the outside and inside are defined with respect to the radial direction R, with the side farther from the center FC of the floor being the outside and the side closer to the center FC of the floor being the inside.

[0010] Apartment building 1 (an example of a building according to the present invention) is rotationally symmetrical when viewed from above, with an atrium 3 located at the center FC of each floor. Multiple sections 2 are arranged circumferentially C around the center FC of each floor, surrounding the atrium 3. The floor area of ​​each section 2 is approximately 70 m². 2 One of the multiple sections 2 is a common area 2B equipped with shared facilities such as stairs and elevators, and the remaining sections are dwelling units 2A. The multiple sections 2 have the same shape and area and are arranged so as a whole they are rotationally symmetrical around the center FC. In this embodiment, there are six sections 2 on one floor, so if each section 2 is rotated 60° around the center FC it will coincide with the adjacent section 2. Each of the multiple sections 2 is a hexagon, and in this embodiment it is an almost regular hexagon. The first floor is also divided into multiple sections 2 in much the same way as the standard floor, and all sections 2 are common areas 2B. The area directly below the atrium 3 is the hall 13. The hall 13 is connected to the vestibule 14A via an automatic door 17, and the vestibule 14A is connected to the approach 14B outside the building via an automatic door 18. The area directly below the dwelling unit 2A is provided with the vestibule 14A, the approach 14B, a machine room (not shown), a bicycle parking area (not shown), etc.

[0011] Apartment building 1 has multiple boundary walls 4 that separate adjacent units 2, an outer wall 5 that defines the outer boundary of the multiple units 2, and an inner wall 6 that defines the inner boundary of the multiple units 2. The boundary walls 4 have an outer end 41 and an inner end 42, and extend radially R between the outer end 41 and the inner end 42. The inner wall 6 is roughly a polygon centered on the center FC of the floor and is connected to the inner ends 42 of the multiple boundary walls 4 via columns 7. A common corridor 9 is provided inside the inner wall 6, and the inside of the common corridor 9 is an atrium 3. A handrail 16 is provided between the common corridor 9 and the atrium 3, and the common corridor 9 and the atrium 3 are considered a single space, however, a partition wall separating the common corridor 9 and the atrium 3 may be provided instead of the handrail 16. A balcony 10 is provided outside the outer wall 5. The balcony 10 facing the common area 2B is optional, but may be provided for design purposes. The inner wall 6 on the first floor does not need to be circular, and parts of it can be omitted depending on the function of each common area 2B. The outer wall 5 has multiple protruding sections 11 and multiple retracted sections 12 that are alternately arranged in the circumferential direction C. Each of the multiple protruding sections 11 protrudes away from the center FC, facing each of the multiple compartments 2. Each of the multiple retracted sections 12 retracts toward the center FC, facing each of the multiple boundary walls 4. With this configuration, the apartment building 1 has an appearance that is significantly different from typical slab-type buildings or tower-type buildings with a rectangular top view, and it is possible to increase the added value of the apartment building 1.

[0012] The structure of the outer wall 5 will now be described in more detail. The outer wall 5 is composed of a plurality of first parts 51 and a plurality of second parts 52. The plurality of first parts 51 are connected to a plurality of boundary walls 4, and the second parts 52 are connected to two first parts 51, each connected to an adjacent boundary wall 4. Specifically, each first part 51 has an inner end 53 closest to the center FC of the floor and an outer end 54 furthest from the center FC of the floor. The inner end 53 of the first part 51 is connected to the outer end 41 of the boundary wall 4 via a column 7, and the outer end 54 of the first part 51 is connected to the second part 52 via a column 7. Two first parts 51 connected to one boundary wall 4 are arranged symmetrically with respect to that boundary wall 4. The two first parts 51, each connected to an adjacent boundary wall 4, and the one second part 52 connected to the two first parts 51 constitute the outer wall 5 of one section 2.

[0013] Two first portions 51, each connected to one of the multiple boundary walls 4, form an angle θ of less than 180° outside the outer wall 5 and around the outer end 54, thereby forming an overhang 11 and a recessed portion 12 of the outer wall 5. The overhang 11 is composed of the portion from the midpoint 55 of the two first portions 51 connected to adjacent boundary walls 4 to the outer end 54 and a second portion 52, while the recessed portion 12 is composed of the portion from the midpoint 55 of the two first portions 51 connected to one boundary wall 4 to the inner end 53. The first portions 51 and the second portions 52 are straight lines, but may also be curved.

[0014] Columns 7 are provided at the connection points between the first section 51 and the second section 52, the connection point between the first section 51 and the boundary wall 4, and the connection point between the inner wall 6 and the boundary wall 4. In other words, the columns 7 are provided at each vertex of the hexagonal periphery of each section 2. Beams 8 are provided between the columns 7. The beams 8 are provided along the hexagonal periphery of each section 2 so as to surround each section 2. Since the interior of each section 2 can be a beam-free space without beams, the ceilings and walls of each section 2, especially in dwelling unit 2A, can be made flat.

[0015] The boundary wall 4 can be made into a seismic wall, while the outer wall 5 and inner wall 6 can be made into partition walls (non-seismic walls). In other words, the boundary wall 4 can be made thicker than the outer wall 5 and inner wall 6. The basic structure of the apartment building 1 is a frame structure composed of columns 7 and beams 8, but by making the boundary wall 4 into a seismic wall, the load on the beams 8 is reduced, so the beams 8 along the outer wall 5 can be made into flat beams. As a result, the window openings provided in the outer wall 5 can be made wider, improving the comfort of dwelling unit 2A.

[0016] Thus, according to this embodiment, since each section 2 protrudes outward, the length of the wall (including the wall facing the atrium 3, hereinafter referred to as the exterior wall) on which windows that allow for natural light, ventilation, and views can be installed can be made wider compared to typical slab-type or tower-type houses. The length of the exterior wall 5 of each dwelling unit 2A is L1, the length of the interior wall 6 is L2, the total length of the boundary walls 4 on both sides is L3, and the ratio of the length of the exterior wall to the total length L1+L2+L3 of the periphery of dwelling unit 2A is defined as the exterior wall ratio. In Figure 3, the exterior walls of dwelling units 2A, 102A, and 202A of this embodiment and comparative examples (slab-type and tower-type houses) are shown with thick lines. In this embodiment, the exterior wall 5 faces the outside of the apartment building 1, and the interior wall 6 faces the atrium 3, so the exterior wall 5 and interior wall 6 constitute the exterior wall. The exterior wall ratio = (L1+L2) / (L1+L2+L3) is approximately 67%. In contrast, in the case of the slab-type house shown in Figure 3(b), the walls facing the balcony 10 and the walls facing the common corridor 9 become the exterior walls. The exterior wall ratio depends on the aspect ratio of the dwelling unit 102A, but is approximately 30-40%. In the case of the tower-type house shown in Figure 3(c), the common corridor 9 is sandwiched between the core space 15 where the common facilities are located and the dwelling unit 202A, so only the wall facing the balcony 10 becomes the exterior wall. The exterior wall ratio depends on the aspect ratio of the dwelling unit 202A, but is approximately 20-30%. Therefore, this embodiment can achieve a much higher exterior wall ratio than slab-type or tower-type houses. In the case of slab-type houses, the exterior wall ratio of the end-gable dwelling units at both ends is usually around 60-70% when the dwelling unit shape is a simple rectangle, but in this embodiment, an exterior wall ratio of approximately 67% can be achieved for all dwelling units 2A.

[0017] If a certain amount of floor space can be secured for the atrium 3, shared facilities can be installed instead of the atrium 3. In this case, all sections 2 can be used as dwelling units 2A. Since the inner wall 6 cannot be used as an outer wall, the outer wall ratio = L1 / (L1+L2+L3) is 50%, but even so, a higher outer wall ratio can be achieved than that of slab houses or tower houses. Therefore, in this embodiment, an outer wall ratio of 50% or more can be secured, further improving comfort. In addition, the length of the balcony 10 also increases accordingly, improving the usability of the balcony 10. Furthermore, since the outer wall 5 of all dwelling units 2A faces in three directions, the amount of time that can receive natural light is increased. Also, for example, even in dwelling unit 2A where the front faces north, natural light can be received from the east and west, thus improving the comfort of all dwelling units 2A.

[0018] Figure 4 shows an example layout of dwelling unit 2A, indicated as A in Figure 1(a). In all examples, dwelling unit 2A has an LDK and three bedrooms BR. The remaining area S contains other facilities such as an entrance, corridor, bathroom, and toilet. The LDK and the three bedrooms BR are living rooms. In the example shown in Figure 4(a), the LDK and the three bedrooms BR are all located facing the exterior wall 5. In the example shown in Figure 4(b), the LDK and two bedrooms BR are located facing the exterior wall 5, and one bedroom BR is located facing the interior wall 6 (open space 3). The LDK faces two entire sides of the exterior wall 5. In the example shown in Figure 4(c), the LDK and two bedrooms BR are located facing the exterior wall 5, and one bedroom BR is located facing the interior wall 6 (open space 3). The one bedroom BR faces two sides of the exterior wall 5. Thus, in this embodiment, multiple living rooms are located in at least one of two positions: facing the exterior wall 5 or facing the open space 3. Furthermore, as shown in Figures 4(b) and 4(c), when a bedroom BR is provided facing the inner wall 6 (opening 3), it is desirable that the windows in the bedroom BR provide the required amount of natural light in order for the bedroom BR to function as a habitable room. Under the Building Standards Act, in order to secure effective daylighting area, the horizontal distance from the window to the adjacent property or other building must be 5m or more in industrial areas and 4m or more in commercial areas. For this reason, the distance D between opposing sides on the inner circumference of the common corridor 9 (see Figure 1(a)) is 5m or more.

[0019] Fig. 5 shows a modified example of the apartment house 1. In the example shown in Fig. 5(a), five compartments 2 are provided on one floor. In the example shown in Fig. 5(b), eight compartments 2 are provided on one floor. In either example, one of the plurality of compartments 2 is a common part 2B, and the rest are dwelling units 2A. The floor area of each compartment 2 is about 70 m as in the first embodiment. 2 In these examples, the plurality of compartments 2 have the same shape and area and are arranged rotationally symmetrically around the center FC. The two first portions 51 connected to each of the plurality of boundary walls 4 form an angle θ of less than 180° outside the outer wall 5 and around the outer end 54, thereby forming the protruding portion 11 and the recessed portion 12 of the outer wall 5. Also, a distance D of 5 m or more is ensured between the opposing sides of the inner peripheral portion of the common corridor 9. Each of the plurality of compartments 2 is hexagonal, but in the example shown in Fig. 5(a), each compartment 2 is flattened in the radial direction R. In the example shown in Fig. 5(b), each compartment 2 is elongated in the radial direction R. Since the first portion 51 can be made longer than the boundary wall 4, it is possible to ensure an outer wall ratio of 70% or more and an outer wall ratio of 50% or more even when not considering the inner wall 6.
