Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apartment house, and more particularly to a maisonette-type apartment house having a structure in which each dwelling unit extends over two floors.
[0002]
[Prior art]
Generally, a house in which a plurality of dwelling units are assembled to form one building is referred to as an apartment house. According to the Building Standards Act, residential-use restricted areas are set (type 1 / type 2 middle / high-rise, type 1 dwelling / type 1). In two types of residential areas / semi-residential areas), the shading regulation is applied to buildings with a height of more than 10 m, and the plan shape / cross-sectional shape of the building is greatly restricted by the planned site shape and the approach road condition. . Here, in a three-story apartment house in which three dwelling units A, B, and C are stacked as shown in FIG. 5, the height can be reduced to 10 m or less, and the building can be constructed without receiving the above-mentioned application. The profitability of apartment buildings is poor, and it is not possible to expect large rent income from rental housing. Therefore, it is conceivable to set up dwelling units in the basement. However, enormous construction costs are required on the basement floor, and it is difficult to anticipate occupants because the image is dark and humid.
[0003]
Also, as shown in FIG. 6, a four-story building above the ground may be used. However, if the height exceeds 10 m, the above application will be applied. If this is forcibly suppressed to 10 m or less, each dwelling unit A ~ The height h of D is as low as about 2.2 m, which gives a feeling of oppression to the occupant, and has a large adverse effect on the habitability.
[0004]
On the other hand, in recent years, as a type of dwelling unit type in an apartment house, in recent years, a multi-layer apartment house in which a dwelling unit having a first floor portion and a second floor portion are stacked has been generally widely constructed (for example, Patent Document 1).
[0005]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 11-200648
[Problems to be solved by the invention]
However, according to the conventional maisonette type apartment house disclosed in Patent Document 1, etc., although the ventilation and privacy can be secured in the second floor of each dwelling unit, each dwelling unit has the first floor and the second floor. Therefore, the number of dwelling units per house is reduced by half, and profitability is deteriorated, even if the number of dwelling units is increased to one. Therefore, it is conceivable to provide two maisonette dwelling units M, M adjacent to each other as shown in FIG. 7, but in this case, the upper and lower floors are narrowed and a comfortable living space is lost. There is a drawback that if the frontage is widened, the floor space will inevitably increase, making it impossible to build on limited land.
[0007]
The present invention has been made in view of the above circumstances, and its purpose is to form as many as possible livable dwelling units even on a small site, and to provide a comfortable living environment and expect high profits for the traders. It is to provide a multi-family housing that can do.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes two maisonette dwelling units provided with a first floor portion and a second floor portion and provided adjacent to each other, and the other second floor portion is partially overlapped on one of the first floor portions, Each maisonette dwelling unit is characterized in that a stairwell leading from the first floor to the second floor is formed.
[0009]
In addition, a two-story multi-family dwelling unit in which a maisonette dwelling unit having a first-floor part and a second-floor part are arranged one above the other, wherein two adjacent maisonette dwellings have one first-floor part on the other two-floor part. Each maisonette dwelling unit is characterized by having a stairwell extending from the first floor to the second floor.
[0010]
Furthermore, it is a multi-story apartment building having two maisonette dwelling units which are provided adjacent to each other with a first floor portion and a second floor portion, and two adjacent maisonette dwelling units are arranged on one first floor portion and on the other floor. It has a structure in which the second floor is partially overlapped, and each maisonette dwelling unit is formed with a stairwell leading from the first floor to the second floor.
[0011]
In particular, in each apartment above, one of the adjacent maisonette dwelling is set to _{1.5L A2 <L} A1 _<3L A2 with respect to the width _{L A2} of width _{L A1} of the first floor section is the second floor portion, the other is width _{L B2} of the second floor portion is set to _{1.5L B1 <L} B2 _<3L B1 with respect to the width _{L B1} in the first floor portion.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example in which a staircase S is interposed between two apartment houses H1 and H2. The apartment houses H1 and H2 each have four maisonette dwelling units 1 arranged one above the other in this example. It is a four-story building with a front width of 8.1 m, a depth of 9 m, and a height of 9.9 m. However, the condominiums H1 and H2 may be a two-story building composed of only two adjacent maisonette dwellings 1, 1 or two adjacent maisonette dwellings 1, 1 may be stacked as one layer, and the three layers may be sequentially stacked. The above multilayer structure may be adopted. Further, each floor may be composed of three or more (preferably even-numbered) maisonette dwelling units 1 to form a tenement house.
[0013]
Furthermore, each maisonette dwelling unit 1 can be constructed by an on-site assembling method, or two adjacent maisonette dwelling units 1, 1 can be factory-produced as a unit, and the unit can be built on site using a jib crane or other heavy equipment. It is also possible to adopt a stacking method.
[0014]
Here, each maisonette dwelling unit 1 has a structure having a first-floor part 11 and a second-floor part 12 having the same height, and two maisonette dwelling units 1, 1 adjacent to each other have one second-floor part 12 on one first-floor part 11. A partially overlapping configuration forms a cubic structure having a predetermined volume with respect to each other.
[0015]
In particular, in the adjacent maisonette dwelling units 1 and 1, as shown in FIG. 2, the width (frontage) of the first floor 11 in one maisonette dwelling unit 1 is L _A1 , the width of the second floor unit 12 is L _A2 , and the other maisonette dwelling unit 1 is shown in FIG. _{L B1} width of the first floor part 11 in the width of the second floor portion 12 as _{L B2,} is set to _{L A1 = 2L A2, L B2} = 2L B1, LA1 = L B2, L A2 = L B1. In this example, L _A1 (L _B2 ) = 5.4 m and L _A2 (L _B1 ) = 2.7 m.
[0016]
Next, FIGS. 3 and 4 show floor plans of the maisonette dwelling unit. First, in the maisonette dwelling unit shown in FIG. 3 (the left maisonette dwelling unit 1 in the apartment house H2 shown in FIG. 1), the first floor portion 11 has a width twice as large as the second floor portion 12, and the first floor portion 11 has a large width. An entrance 21 is provided at the front center, and a toilet 22 is provided next to the entrance 21. Further, a room 25 (about a six-tatami-mat Western-style room) provided with a closet 24 across a corridor 23 extending from the entrance 21, and a washroom 26 and a bathroom 27 are provided. The space on the rear side is a living room 28 and a dining kitchen 29. Further, outside the first floor 11, a shared passage 30 is provided in front of the first floor 11, and a balcony 31 is provided behind the shared passage 30.
[0017]
On the other hand, a balcony 32 for installing an outdoor unit or the like of an air conditioning system is provided in front of the narrow second floor portion 12 which is vertically long, and an eave 33 is provided in an upper rear portion. The front of the second floor 12 is a room 35 having a closet 34 (a Western-style room of about 6 tatami mats), and the rear of the room is a blowout 36 occupying half the area of the second floor 12. The blow-out 36 is opened above the living room 28 on the first floor 11, where a stair 37 (a spiral stair in this example) is provided.
[0018]
Next, in the maisonette dwelling unit shown in FIG. 4 (the left maisonette dwelling unit 1 in the apartment house H1 shown in FIG. 1), the second floor portion 12 is wider than the first floor portion 11 (in the second floor portion), contrary to the maisonette dwelling unit shown in FIG. Double the size). An entrance 41 and a toilet 42 are provided adjacent to each other in front of the narrow first floor 11 which is vertically long, and a kitchen 43 and a living room 44 are provided behind the entrance 41 and the toilet 42. Further, a stair 45 leading to the second floor 12 is provided in the living room 44. Further, outside the first floor 11, a shared passage 46 is provided in front of the first floor 11, and a balcony 47 is provided behind the shared passage 46.
[0019]
On the other hand, the wide second floor 12 is also provided with balconies 48 and 49 on both front and rear sides thereof, and two rooms 52 and 53 having closets 50 and 51 (approximately 6 tatami-style Western rooms) are provided adjacent to each other in front of the inside. . Numeral 54 designates a stairwell leading from the first floor to the second floor. The stairwell 54 occupies the rear half area of the first floor 11 and is opened on the living room 44, where the stairs 45 are arranged. In addition, a walking closet 55, a washroom 56, and a bathroom 57 are provided behind the inside of the second floor section 12 facing the blowout 54.
[0020]
As described above, according to the apartment house, in each of the maisonette dwelling units 1, one of the first floor portion 11 and the second floor portion 12 is made wide, and the large-diameter blow-off hole 36 occupying approximately half the area of the narrow floor. , 54 are formed on the living rooms 28, 44, so that the ceiling surfaces of the first floor portion 11 and the second floor portion 12 are each set to be as low as about 2.2 to 2.5 m while giving a sense of openness. An excellent living space can be created.
[0021]
Although the application example of the present invention has been described above, the layout of each maisonette dwelling unit is not limited to the above example, and the arrangement position of each room may be changed as necessary. Further, in each maisonette dwelling unit 1, either one of the first floor unit 11 and the second floor unit 12 is not limited to be twice the width of the other, and the first floor unit 11 and the second floor unit 12 of the adjacent maisonette dwelling units 1, 1 are not limited to one. , The widths L _A1 and L _A2 and L _B1 and L _B2 may be set to 1.5 L _A2 <L _A1 <3L _A2 , and 1.5 L _B1 <L _B2 <3L _B1 (L _A1 = L _B2 ). .
[0022]
In the setting of 1.5L _A2 > L _A1 and 1.5L _B1 > L _B2 , both the first floor and the second floor in each maisonette dwelling unit become narrow, and it becomes impossible to install large furniture, which is prevented. If it is widened as much as possible, it will not be possible to build on a narrow site.
[0023]
On the other hand, in the setting of L _A1 > 3L _A2 and L _B2 > 3L _B1 , even if large furniture can be installed on a wide floor, the volume occupied by the blow-out becomes smaller than the total volume, so that the feeling of oppression is strong. Performance will be greatly reduced.
[0024]
【The invention's effect】
As is apparent from the above description, according to the present invention, since the maisonette dwelling unit having the first floor and the second floor is a single- or multi-layered apartment house provided adjacent to each other, it is subject to the shading regulation. It is possible to form as many dwelling units as possible on a small site without any restrictions and to increase profits.
[0025]
Adjacent maisonette dwelling units have a structure in which the first floor is partially overlapped with the other two floors, and each maisonette dwelling has a stairwell leading from the first floor to the second floor. As a result, a comfortable living space with a feeling of openness is created, and large furniture can be installed on the wide floor.
