Japanese Patent No. 5297028 JP, 2004-169420, A

Generally, each dwelling unit of an apartment house is planned to have a rectangular shape as much as possible. A rectangular dwelling unit is preferable from the viewpoint of efficiency in arranging beds, furniture, etc. because it is easy to make each room rectangular. On the other hand, enlarging the frontage of the dwelling unit on the outer wall side is important not only for daylighting but also for the view, and dwelling units with a large frontage are said to be more valuable. However, in order to expand the frontage of a rectangular dwelling unit, it is necessary to widen the dwelling unit itself or to make it slender with a wider frontage, which is a major limitation in planning. In addition, although the dwelling unit at the corner of the building is advantageous from the frontage perspective, it is difficult to effectively use the dwelling unit because the living room is made as rectangular as possible so that it often has an irregular shape that combines a rectangle and a trapezoid. ..

It is an object of the present invention to provide an apartment house in which a large frontage can be easily secured and the dwelling units can be effectively used.

The housing complex of the present invention has an inner core space and a plurality of dwelling units in the circumferential direction along the core space. At least one of the plurality of dwelling units has two linear boundary walls that define a circumferential boundary, and the distance between the two linear boundary walls in the circumferential direction decreases toward the core space.

According to the present invention, it is possible to provide an apartment house in which a large frontage can be easily secured and the dwelling units can be effectively used.

It is a top view of one dwelling unit of the apartment complex shown in FIG. It is a top view of a dwelling unit of a comparative example. It is a top view of an apartment house which concerns on other embodiment of this invention. It is a top view of the housing complex of a comparative example. It is a top view of the housing complex which concerns on the other modification of this invention.

Hereinafter, some embodiments of an apartment house of the present invention will be described with reference to the drawings. The apartment house of the present invention can be suitably applied mainly to a high-rise tower apartment house (so-called tower condominium), but the number of floors of the apartment house is not particularly limited, and it can be applied to an apartment house of any floor number. In the following description, the radial direction D1 means a direction away from the center 1A of the housing complex 1, and the circumferential direction D2 means a clockwise or counterclockwise direction with respect to the center 1A of the housing complex 1.

FIG. 1 is a plan view of a housing unit installation floor of an apartment house 1 according to an embodiment of the present invention. The housing complex 1 has a generally sixteen-dimensional planar shape. The housing complex 1 has an inner peripheral frame 2, an outer peripheral frame 3 provided outside the inner peripheral frame 2, and an outer wall 4 provided along the outer peripheral frame 3. Inside the inner peripheral frame 2 is a core space 5 provided with vertical shafts such as elevators, staircases, pipe shafts, and blowouts. In the horizontal cross section of the housing complex 1, the outer wall 4 and the core space 5 have a substantially regular polygonal or circular shape, and the center of the outer wall 4 (center 1A of the housing complex 1) and the center 5A of the core space 5 coincide with each other. There is. A plurality of dwelling units 6 are provided along the core space 5 in the circumferential direction D2 between the inner peripheral frame 2 and the outer peripheral frame 3. Each dwelling unit 6 is partitioned from two dwelling units 6 on both sides adjacent to each other by two boundary walls 7 that define a boundary of the dwelling unit 6 in the circumferential direction D2. A corridor (not shown) is provided along the inner frame 2 between the core space 5 and the dwelling units 6 so that each dwelling unit 6 can be accessed. A balcony BL is provided along the outer periphery of the housing complex 1. The planar shape of the housing complex 1 is not limited to the regular sixteen shape, but may be any shape that can be regarded as a circular shape or a shape close to a circular shape, and may be, for example, a circular shape or a regular polygonal shape having eight or more corner portions.

The inner peripheral frame 2 has a plurality of inner columns 2A provided at predetermined intervals and an inner beam 2B continuously provided in the circumferential direction D2 along the plurality of inner columns 2A. The outer peripheral frame 3 has a plurality of outer columns 3A provided at predetermined intervals, and an outer beam 3B continuously provided in the circumferential direction D2 along the plurality of outer columns 3A. The inner peripheral frame 2 and the outer peripheral frame 3 are frames composed of columns and beams, and walls (shakeproof walls) as structural elements are not provided. The core space 5 is also provided with a frame structure of beams and columns or a seismic wall (not shown). The structure of the floor slab is not particularly limited, but by using a half PCa floor slab, for example, a beamless structure can be realized while improving workability.

All the dwelling units 6 on one floor have a linear boundary wall 7, and the distance L between the two linear boundary walls 7 in the circumferential direction D2 decreases toward the core space 5 or the center 1A of the housing complex 1. ing. The distance L in the circumferential direction D2 is the length of a straight line connecting the points P1 and P2 on the two boundary walls 7 that have the same distance from the center 1A of the housing complex 1. In this embodiment, all the dwelling units 6 on one floor have a substantially trapezoidal shape or a substantially partially annular shape. Here, the partial annular shape means a shape obtained by cutting a fan shape with concentric circles having a smaller diameter than that, or a region surrounded by two concentric circles having different diameters and two line segments passing through the centers of the concentric circles. .. It should be noted that all the dwelling units 6 on one floor do not have to have the same size, and in the embodiment shown in FIG. 1, three types of dwelling units 6 having different areas are provided (dwelling units around 12:00 on the clock). 6 is the smallest area, the dwelling unit 6 around 6 o'clock on the clock has the largest area, and the other dwelling units 6 are in the middle of these areas). The length of the dwelling unit 6 in the radial direction D1 (hereinafter referred to as depth) is the same for all dwelling units 6, and the width of the dwelling unit 6 in the circumferential direction D2 (hereinafter referred to as width) differs depending on the dwelling unit 6. The width of the dwelling unit 6 is obtained by finding an intersection between an arbitrary virtual circle (for example, the virtual circle 8 shown in FIG. 1) centering on the center 1A of the housing complex 1 and the two boundary walls 7, and calculating the straight line distance of the intersection. Can be asked as

Next, an example of planning of each dwelling unit 6 will be described with reference to FIGS. 2 to 4 are examples of 3LDK dwelling units 6A to 6G, 106 having a floor area of about 75 m ² , and FIG. 2 illustrates an embodiment (dwelling units 6A to 6C) in which all living rooms face the balcony BL. 3 shows an embodiment (dwelling units 6D to 6G) in which some living rooms face the balcony BL, and FIG. 4 shows a dwelling unit 106 of a comparative example. Living room means a living room under the Building Standards Act, and specifically means LDK, master bedroom, and bedroom. Although the LDK is provided in each of the embodiments and the comparative examples, the kitchen of the LDK may be partitioned to be LD+K. In the present specification, LDK is used to include LD in LD+K. The dwelling units 6A to 6G of the embodiment shown in FIGS. 2 and 3 correspond to the dwelling unit A of FIG. 1, and all have the same planar shape and the same size. The dwelling units 6A to 6G of the respective embodiments have a substantially trapezoidal shape or a substantially partially annular shape except for an irregular portion near the entrance, and have a depth of 9 m and a frontage of 11.1 m. The outer boundary of each of the dwelling units 6A to 6G in the radial direction D1 has the entire length along the outer wall 4 of the building or the balcony BL. The boundaries of the dwelling units 6A to 6G on the core space 5 side have an irregular shape, but may have a linear shape.

The dwelling unit 106 of the comparative example has a rectangular shape with a depth of 9.5 m and a frontage of 8 m. In the comparative example, an L-shaped LDK is arranged in the center, a main bedroom and two bedrooms are arranged around the LDK, and water areas such as toilets, washrooms, and bathrooms are collectively arranged on the core space 5 side. In principle, the LDK, main bedroom, and bedroom, which are living rooms under the Building Standards Act, are required to have an opening (window) for lighting. In the comparative example, the LDK, the main bedroom, and one bedroom face the balcony BL, and the other bedrooms do not face the balcony BL. However, the bedroom not facing the balcony BL can comply with the Building Standard Law by adopting "two room lighting" through the LDK. In this case, since the bedroom does not face the core space 5, it is necessary to adopt a door such as a two-sliding door (not shown) in order to make it an integrated space with the LDK.

On the other hand, in each embodiment shown in FIG. 2, the LDK, the main bedroom, and the two bedrooms all face the balcony BL. In the embodiment shown in FIG. 2A, the LDK has a shape close to a rectangle that extends in the radial direction D1 from the balcony BL to the core space 5 side. The main bedroom and the two bedrooms are arranged along the balcony BL, and each has a substantially rectangular shape that is long in the radial direction D1. In this embodiment, all living rooms (LDK, main bedroom and two bedrooms) are accessible from the corridor. In the embodiment shown in FIG. 2B, the LDK is L-shaped, and the main bedroom is provided on one side of the LDK and the two bedrooms are provided on the other side. In this embodiment, the LDK and the main bedroom are accessible from the corridor, and the two bedrooms are accessible from the LDK. Therefore, in this embodiment, the area of the corridor is smaller than that of the embodiment shown in FIG. In the embodiment shown in FIG. 2C, the LDK is L-shaped, and the main bedroom and two bedrooms are arranged between the LDK and the balcony BL. In this embodiment, only the LDK is accessible from the corridor, and the main bedroom and the two bedrooms are accessible from the LDK. Therefore, the area of the corridor is the smallest in the embodiment shown in FIG.

In each of the embodiments shown in FIG. 2, part of the LDK is arranged between at least one bedroom and the core space 5. In any of the embodiments, water facilities such as toilets, washrooms, and bathrooms are collectively arranged on the core space 5 side. As described above, since all the living rooms are adjacent to each other and face the balcony BL, the width of at least one living room decreases toward the core space 5. In each embodiment shown in FIG. 2, the bedroom having a small area has a rectangular shape, and the width of the LDK having a large area decreases toward the core space 5 on the balcony BL side. In other words, at least one living room (LDK in this embodiment) has a portion whose width decreases toward the core space 5. In the example shown in FIGS. 2A and 2C, the width of the main bedroom decreases toward the core space 5, but in the example shown in FIG. 2B, the width is almost constant.

In each of the embodiments shown in FIG. 3, one bedroom including the LDK and the main bedroom faces the balcony BL, and the other bedrooms do not face the balcony BL, as in the comparative example. In the embodiment shown in FIGS. 3A and 3B, the main bedroom and the bedrooms are arranged on both sides of the LDK, and the remaining bedrooms are arranged on the core space 5 side of the main bedroom. Fig. 3(a) is a plan that maximizes LDK by minimizing the corridor, and Fig. 3(b) is a plan that uses the corridor as the flow line to the water field. In the example shown in FIGS. 3C and 3D, two bedrooms are arranged on one side of the LDK, and the main bedroom is arranged between the two bedrooms and the core space 5. FIG. 3(c) is a plan in which the bathroom faces the balcony BL (view bath plan), and FIG. 3(d) is a plan in which the frontage of the LDK is maximized. Note that, as in the comparative example, the bedroom not facing the balcony BL can be made compliant with the Building Standards Law by adopting "two room lighting" through the LDK. In this case, depending on the positional relationship with the core space 5, the bedroom may need to adopt a door such as a two-sliding door (not shown).

In each of the embodiments shown in FIGS. 2 and 3, the frontage on the outer wall 4 side is 11.1 m, which is about 40% larger than that of the comparative example. Comparing only the frontage, the floor area of the dwelling units 6A to 6G of the present embodiment corresponds to the floor area of 100 m ² or more in the comparative example. For this reason, in each of the embodiments shown in FIG. 2, four living rooms can be arranged along the outer wall 4 without difficulty even though the floor area is the same as that of the comparative example. On the other hand, in each of the embodiments shown in FIG. 3, the frontage of the LDK is about twice as large as that of the comparative example, and particularly in the embodiment shown in FIG. You can Furthermore, since the frontage has a margin, the view bus plan shown in FIG. 3C is also possible.

By making the shape of the dwelling units 6A to 6G into a trapezoidal shape or a partial annular shape having a large width on the outer wall 4 side and a small width on the core space 5 side, the entire dwelling unit can be efficiently used. Generally, in an apartment house having a core space, a living room that needs lighting is preferentially placed on the balcony side (outer wall side of the apartment house). On the other hand, the core space side only requires the entrance, and there are no major restrictions on the installation location of water areas such as bathrooms, toilets, and washrooms. However, since the living room occupies a large area in the dwelling unit, in the case of a rectangular dwelling unit, only the living room is arranged on the balcony BL side, and the unusable living room is arranged on the core space 5 side as in the comparative example. The field is consequently arranged on the core space 5 side. If the portion outside the center line 9 in the radial direction D1 (depth direction) of the dwelling unit 106 is the outer portion SO and the portion inside the center line 9 is the inner portion SI, the areas of the inner portion SI and the outer portion SO in the comparative example are Since it is the same, it is possible to efficiently use the outer portion SO, which has many things to be installed, by disposing the LDK or the bedroom. On the other hand, the inner part SI has many small areas such as bathrooms, toilets, and washrooms, and thus the degree of freedom in planning is high, but there are few things to be actively arranged. Therefore, it is difficult to effectively use the inner portion SI. As a result, the area of the water and the entrance may become larger than necessary. For example, although it is possible to give a certain added value to the entrance by arranging a shoe closet or the like, it is still difficult to effectively and efficiently use the inner portion SI.

On the other hand, in this embodiment, since the dwelling units 6A to 6G are trapezoidal or partially annular, it is possible to secure a large area on the balcony BL side and reduce the area on the core space 5 side. Assuming a simple partial annular shape, the outer portion SO is a portion outside the center line (imaginary circle 8 in FIG. 1) in the radial direction D1 (depth direction) of the dwelling units 6A to 6G, and the inner portion SI is the center in the radial direction D1. Assuming that the portion is inside the line, the area ratio between the outer portion SO and the inner portion SI is (19 ² -(19-4.5) ² ):((19-4.5) ² based on the dimensions shown in FIG. 1, for example. -(19-9) ² )=(361-210.25):(210.25-100)=150.75:110.25=1.37:1, and the outer portion SO is slightly larger than the inner portion SI by slightly less than 40%. That is, in the present embodiment, it is possible to increase the area of the outer portion SO having a high utility value and reduce the area of the inner portion SI having a relatively low utility value, while making the entire floor area equal to that of the comparative example. FIGS. 2 and 3 show an example of planning, but by utilizing the characteristic of the shape that the outer portion SO can be secured larger than the inner portion SI, the entire dwelling unit can be used efficiently.

Further, based on the description of FIG. 1, the ratio of the perimeter of the outer wall 4 side to the perimeter of the core space 5 side of each dwelling unit is approximately 19:10 (assuming double concentric circles). There is a large difference between the frontage on the side of the outer wall 4 having a high utility value and the frontage on the side of the core space 5 having a relatively low utility value. In other words, it is possible to prevent the floor area of the dwelling unit from unnecessarily increasing by narrowing the frontage on the core space 5 side, and it is possible to improve the cost performance of the dwelling unit.

FIG. 5 shows a plan view of apartment houses 101 and 201 according to another embodiment. In the housing complex 101 shown in FIG. 5A, the corner portion C has a rectangular shape with a corner cut (or, although not shown, it may be rounded into a curved surface). Each of the dwelling units 6 has an irregular quadrangular or hexagonal shape so as to have approximately the same area, and the distance L in the circumferential direction D2 between the two linear boundary walls 7 is the same as that of the housing complex 1 shown in FIG. Similarly, it decreases toward the core space 5. In the housing complex 201 shown in FIG. 5B, the dwelling units 106 along the sides between the corner portions C have a rectangular shape. On the other hand, the dwelling unit 6 at the corner portion C has an irregular pentagonal shape, and the distance L between the two linear boundary walls 7 in the circumferential direction D2 decreases toward the core space 5. In the embodiment shown in FIG. 5A, the interval L in the circumferential direction D2 between the two linear boundary walls 7 in all the dwelling units 6 on one floor decreases toward the core space 5, and FIG. In the embodiment shown in b), the spacing L in the circumferential direction D2 of the two linear boundary walls 7 decreases toward the core space 5 only in some of the dwelling units 6 on one floor. Also in these apartment houses 101 and 201, for the dwelling unit 6 in which the distance L between the two linear boundary walls 7 in the circumferential direction D2 decreases toward the core space 5, the planning as illustrated in FIGS. Is possible.

As shown in FIG. 6, in the conventional housing complex 301, each dwelling unit 106 has a rectangular shape as much as possible, and the corner portion C also has an irregular shape in which a rectangle and a trapezoid are combined. Since the dwelling unit 106 other than the corner portion C has the shape of the comparative example shown in FIG. 4, it is more disadvantageous than the present embodiment in terms of securing a frontage and effectively using the entire dwelling unit. The dwelling unit 206 in the corner portion C may be more advantageous than the present embodiment in securing a frontage, but since the shape is irregular, a wasteful space is likely to occur from the viewpoint of effective use of the dwelling unit, It is more disadvantageous than the form. This problem does not occur if all of the corners C are made into one dwelling unit 306, but the floor area becomes twice as large as that of the other dwelling units 106 and 206, and there is a possibility that it will not be a realistic planning. On the other hand, in the present embodiment, since the horizontal cross section of the housing complex 1 is a regular polygon, the distance L in the circumferential direction D2 between the two linear boundary walls 7 of all the dwelling units 6 on one floor is the core space. It is easy to make the shape to decrease toward 5, and the value of the housing complex 1 itself can be increased. Further, by adjusting the angle θ (see FIG. 1) occupied by each house 6, it is easy to provide various houses 6 having similar shapes and different floor areas, and the degree of freedom in planning can be increased.

FIG. 7 shows a plan view of an apartment house according to another modification of the present invention. In this figure, only the outer peripheral frame 3 and the inner peripheral frame 2 are shown. In the above-described embodiment, the housing complex is a circle or a regular polygon having eight or more corners, but the housing complex may be an irregular polygon as shown in FIG. 7A. An irregular polygon is a polygon in which the angle of at least one corner differs from the angle of the other corners. The housing complex may be a regular polygon having 3 to 7 corners or an irregular polygon (not shown). As shown in FIG. 7B, the housing complex may be elongated in one direction. The elongated shape includes a shape in which a semicircle, a rectangle, and a semicircle are connected in this order in the longitudinal direction, an elliptical shape, and the like. Further, as shown in FIGS. 7(c) and 7(d), the housing complex may have a shape such as a semi-circular shape in which a part of the circumference is lost. In the example shown in FIGS. 7C and 7D, the core space 5 is partially surrounded by the inner frame 2. These modifications are effective, for example, when there is a restriction on the site shape, and the present invention can be applied as in the above-described embodiment.
