Description

  The present invention relates to an apartment house having a two-story maisonette dwelling unit.

  Conventionally, ramen structures are often used in apartment houses such as apartments and apartments. In recent years, a building structure is supported by a bearing wall provided along two axes on a plane, so that a column structure or a beam structure does not protrude into a living room, or a combination of a ramen structure and a wall structure. A wall-type frame structure (for example, refer to Patent Document 1) that supports a load in the beam direction with a wall column and a wall beam and supports a load in the beam direction with a load-bearing wall provided as a boundary wall. ing.

On the other hand, in condominiums such as condominiums, on the other hand, a plate-shaped house formed in a substantially rectangular parallelepiped is a slab provided at a predetermined floor height in the vertical direction, and a doorway wall provided in a set frontage dimension in the horizontal direction. As a result, a plurality of dwelling units are often defined in a rectangular parallelepiped at each level. In recent years, there are an increasing number of housing complexes that have changed living spaces in order to improve the comfortability and create a detached feeling. As such an apartment house, one with a large floor height set for the top floor dwelling unit, one provided with a maisonette dwelling unit having a plurality of floors (for example, refer to Patent Document 2), storage of ceiling height for half a floor There is known one in which a space for use is provided between vertically adjacent dwelling units (see Patent Document 3).

  By the way, an apartment building usually has an entrance on the north side and a living space on the south side. Recently, in order to improve the daylighting of the living space and get a feeling of opening, the south side window has been made as large as possible. Dwelling units tend to be preferred. Moreover, in a housing complex where the floor area is constant and cannot be expanded, it is desirable to secure a storage space in a limited space.

  However, in conventional maisonette dwelling units, if the living room is blown away to improve the feeling of opening of the living space and lighting, the ceiling height becomes larger than necessary, making it difficult to adjust the heating and cooling, and the ceiling lighting There was a problem that the maintenance was dangerous, and there was a problem that the construction cost for the floor area of the maisonette dwelling unit was high. In addition, the atrium with a ceiling height of two floors is an excessive space for people to live in, resulting in a decrease in visibility in the living room, lack of space integrity and economics of the building, and high construction costs. On the other hand, the effective use of space was insufficient.

  This invention is made | formed in view of such a background, and it aims at providing the housing complex which can change a living space at comparatively low cost, and can utilize space effectively.

In order to solve the above problems, according to an aspect of the present invention, a two-level maisonettes dwelling unit (4M), collective housing having 1 and hierarchy dwelling unit (4S) adjacent to the upper side of Maisonette housing door (1) However, the border slabs (9, 10) that divide the maisonette dwelling unit (4M) and the one- level dwelling unit (4S) are partially biased toward the maisonette dwelling unit (4M) by about half a floor. It is constituted so that it may be formed as a half-story slab (10) arranged in a row.

According to this configuration , the ceiling height of the adjacent one- level dwelling unit can be increased because a part of the door-to-door slab is located on the approximately half floor of the maisonette dwelling unit. Therefore, while suppressing an increase in the construction cost with respect to the floor area, a high ceiling feeling, daylighting ability, and space integrity can be obtained by an appropriate ceiling height suitable for the human scale. In addition, the maisonette dwelling unit increases the storage space by using the space formed by the half-floor slab as an underfloor storage or loft, and the one- level dwelling unit provides a separate slab in the space formed by the half-floor slab. The space can also be used effectively. In addition, if these ceiling heights are set so as not to be included in the floor area of the Building Standard Law, the effective space can be increased without causing an increase in the floor area.

Further , according to one aspect of the present invention, in addition to the above-described configuration, the one- level dwelling unit (4S) has a skip floor (4s) side formed by the half-story slab (10), and the ceiling height (h ₁ ) of the first level. Has a large ceiling height (h _1.5 ), and the maisonette dwelling unit (4M) is configured so that the half-story slab (10) side is blown through (4t).

According to this configuration , a one- level dwelling unit has a large skip floor with a large ceiling height, which gives a change in the living space and increases comfort, and also provides high openness and daylighting. Since the skip floor on the half-slab slab side is atrium, it is possible to obtain high openness and daylighting due to a large ceiling height in the same way as a one- level dwelling unit.

Moreover, according to one aspect of the present invention, in addition to the above configuration, the apartment house is made of reinforced concrete or steel-framed reinforced concrete, and is formed at the boundary with the half-story slab (10) in the doorside slab (9, 10). A wall-type frame structure having a wall beam (8) and a plurality of wall columns (7) whose cross section is long in the extending direction of the wall beam in order to support the wall beam. A first load bearing wall that extends along a direction orthogonal to the extending direction of the wall column, is arranged on the half-story slab side of the wall column, and is connected to one end side of the wall column in the extending direction ( 11) and extending in a direction orthogonal to the extending direction of the wall column in plan view, and disposed on the opposite side of the half-story slab in the wall column and extending in the extending direction in the wall column as further has a second bearing wall which connects the other end (12) It is formed.

According to this configuration , by using the boundary with the half-story slab in the doorside slab, that is, the stepped part as a frame, the beam protrudes into the living space, and the rigidity of the building is not reduced without causing deterioration in openness and comfort. Yield can be increased. In addition, the first and second load-bearing walls and the wall pillar 7 have a crank shape in plan view, and the wall pillar does not protrude into the living space, so that a high degree of freedom in floor plan and an open space can be realized. Furthermore, since the wall column is restrained by both bearing walls on both sides in the longitudinal direction, the rigidity of the wall column can be increased.

Moreover, according to the other aspect of this invention, it replaces with the said structure and a 1st- level dwelling unit (4S) adjoins the downward direction of a maisonette dwelling unit (4M), and a 1st- level dwelling unit (4S) is a half-story slab (10). The floor on the side has a ceiling height (h _1.5 ) larger than the ceiling height (h ₁ ) of one floor, and the maisonette dwelling unit (4M) is a skip floor (4s) formed by a half-story slab (10) Is configured to be blown through (4t).

According to this configuration , the first floor dwelling unit has a large ceiling height on the half-story slab side to obtain high openness and lighting, and the maisonette dwelling unit has a skip floor on the half-story slab side for comfort. A high living space is formed, and the skip floor is blown out, so that it is possible to obtain high openness and daylighting due to a large ceiling height in the same way as a one- level dwelling unit.

  ADVANTAGE OF THE INVENTION According to invention, the housing complex which can change a living space at comparatively low cost and can utilize space effectively is provided.

The entire space extending from the 7th floor and the 8th floor forms one maisonette dwelling unit 4M. This maisonette dwelling unit 4M has a ceiling height h ₂ (h ₂ ≈h ₁ × 2) in which the aerial 4t portion has two levels. The maisonette dwelling unit 4M.

  FIG. 4 is a cross-sectional view taken along the line IV-IV in FIGS. As shown in FIGS. 2 and 4, the building 1 has four wall pillars 7 arranged on the inner side of the outer wall 13 of the building 1 at a predetermined interval in the east-west direction (in the direction of the rows). Each of these wall pillars 7 is arranged so that a cross section thereof is long in the direction of the line (in plan view). As shown in FIG. 4, each wall column 7 is connected by wall beams 8 extending in the column direction at two intermediate portions in the height direction. The wall beam 8 connects the four wall columns 7 and also connects the wall columns 7 and the outer wall 13 arranged at both ends.

  As shown in FIG. 2, one end 7 a of each wall column 7 is connected to a first bearing wall 11 extending in the inter-beam direction and extending southward from the wall column 7, and the other end of each wall column 7. 7b is connected to a second load bearing wall 12 that extends in the inter-beam direction and extends from the wall column 7 to the north side. In addition, the outer wall 13 arrange | positioned at the east-west both ends of the building 1 and the inner wall 14 arrange | positioned at the center part of the east-west direction of the building 1 also function as a bearing wall.

  As shown in FIGS. 1 and 2, the first load bearing wall 11 has no so-called flat plate structure in the vicinity of the south end thereof, and has a so-called flat plate structure. The south side is a full window. In order to fix the sash, a reinforced concrete frame having a small cross-sectional dimension is formed between the window 16 and the first bearing wall 11 on the south surface of the dwelling unit.

  On the other hand, the second load-bearing wall 12 also has a flat plate structure in the vicinity of the north side end thereof without a column or beam serving as a frame, and the two adjacent second load-bearing walls 12 It is connected by RC walls, windows, entrance doors, etc. that divide the balcony 4b and the living room. Therefore, as shown in FIG. 2, not only can the entrance 4e be recessed toward the room side to ensure privacy, but the wall surface on the shared corridor 5 side can be variously laid out without being restricted by pillars or beams. The living room and bathroom on the north side can also be laid out without being affected by pillars.

Thus, by Kabehari 8 is respectively provided between the second floor and half floor slab 10 of the south in the 5th and the north side of the third floor slab 9 _3, 6th floor slab 9 _6, pilasters 7 Beam It is connected by a large wall beam 8 to ensure a large rigidity and proof strength in the building 1 and enables a skip floor plan with a wall-type ramen structure. Further, since Kabehari 8 located on the stepped portions of the slab (3 floor slab _{9 3} a half floor slab _{10 2.5,} and the sixth floor slab _{9 6} semi floor slab _{10 5.5),} RyoNaru large However, the openness and comfort of the living space are ensured. And since it is possible to enlarge the beam formation of the wall beam 8 without impairing the openness and comfort of the living space, the wall beam 8 is arranged only in the middle part in the north-south direction in the building 1, and the building 1 It is possible to adopt a flat plate structure in which columns and beams are not provided on the south surface and the north surface, the south surface of the dwelling unit 4 is an open full glass window, and the north surface of the dwelling unit 4 can be freely laid out. . The living space has no irregularities due to the pillar shape or beam shape, and the space is less wasted compared to the ramen structure.

  Further, when the skip floor 4s is formed, the structure is complicated in the ramen structure, but the building 1 has a wall-type ramen structure, and the step portion of the skip floor 4s is used as the wall beam 8 to simplify the structure. The skip floor 4s is realized with a simple structure, and the comfort is enhanced while changing the living space. That is, the wall beams 8 of the wall structure are arranged using the steps of the skip floor 4s, so that the design (space) plan and the structure plan are integrated, and the rigidity of the building 1 is ensured and the space is effectively used. And coexistence is possible.

  Further, the first load-bearing wall 11 is connected to one end 7a of the wall column 7 and the second load-bearing wall 12 is connected to the other end 7b of the wall column 7, so that the load-bearing walls 11, 12 and the wall column 7 are seen in a plan view. Thus, the wall pillar 7 does not protrude into the living space, and a high degree of freedom in floor plan and an open space are realized. Moreover, since the wall column 7 is restrained by the bearing walls 11 and 12 on both sides in the longitudinal direction, the rigidity of the wall column 7 is also increased. The first and second load-bearing walls 11 and 12 can be connected not to the end portion of the wall column 7 but in the vicinity of the end portion, and the degree of freedom in design can be increased by changing the connection position according to the layout. Further increase.

On the other hand, the 6th floor slab 9 ₆ are provided only on the north side, by the seventh floor slab 9 ₇ entire surface provided at the same height, are formed by a semi-floor slab 10 _5.5 located 5.5 floor The ceiling height h _1.5 of the skip floor 4s is increased, and a wide field of view that realizes an excellent open feeling and a view is provided. By ceiling height h _1.5 6 floor of dwelling units 4 skip floors 4s and the floor of the lower (4 floor) are both 1.5 hierarchy min, the following effects can be obtained. That is, in conventional blow 4t as shown on the seventh floor, or becomes difficult to adjust the heating and cooling increases the ceiling height h ₂ than necessary, disadvantageously or with the risk to maintenance of the illumination of the ceiling portion and, There was a problem that the construction cost for the floor space of the maisonette dwelling unit 4M having the atrium 4s was high, but the ceiling height h _{1.5 of} the skip floor 4s and the floor below it (fourth floor) matched the human scale. By becoming appropriate, it is possible to obtain a sufficient feeling of openness and the integrity of the space with a reasonably large ceiling height h _1.5 while suppressing such problems and problems.

On the other hand, when the half-floor above the slab 10 _2.5 located 2.5 floor third floor slab 9 ₃ is provided, for the residents to emphasize high storability than wide living space, the space formed between the semi-floor slab 10 _2.5 located 2.5 floor and the third floor slab 9 ₃ can be provided as an underfloor storage, enabling space designed to meet the needs of users It has become. In addition, underfloor storage and lofts with a predetermined ceiling height are not included in the floor area of the Building Standard Law, so that the space that can be used even with the same floor area can be increased. In this case, since the underfloor storage is a buffer area of the noise, it is possible to reduce the noise such as footsteps transmitted from the third floor slab 9 _3, to improve the sound insulation in the floor (first floor) adjacent downward. It should be noted that, in the south part of the third floor slab 9 _3, by adopting a wooden rather than the RC structure, it is easy, such as changing to a large living room ceiling height abolished the storage box in accordance with the future life style.

  Moreover, the building 1 can be made into a middle-high-rise building by providing the seismic isolation device 3 while having a wall-type ramen structure.
