Description

  The present invention relates to an apartment house, and particularly to an apartment house suitable for construction as a high-rise or super-high-rise building on a relatively small site.

2. Description of the Related Art Conventionally, a plate-like house having a balcony-side ramen construction surface and a shared corridor-side (entrance-side) ramen construction surface that forms a crossing direction of a building and a plurality of dwelling units arranged in the crossing direction is widely known. . As such plate-like houses, there are known a long and flat one-side corridor type apartment house and a staircase type apartment house that is a type in which each dwelling unit is directly accessed by a staircase.
However, it is difficult to construct a plate-shaped large-area one-way apartment complex with a large number of dwelling units arranged in the direction of the line in an urban environment where the site is limited. In order to secure the number of units on a limited site, it is only necessary to increase the number of buildings. However, a building in the form of a one-way corridor type plate-like apartment is sufficient in the direction between the beams, which is the short side direction. Since it is difficult to obtain rigidity, it is difficult to realize a high-rise or super-high rise. This is the reason why single-story corridor type apartment houses are often found in relatively low-rise buildings.
In addition, staircase type apartments, like the one-way corridor type apartments, are difficult to secure the rigidity in the beam direction, and there is a problem of where and how to arrange the elevators. It is difficult to do.
Currently, high-rise or ultra-high-rise urban houses are realized by tower-type apartments that surround or roll around the core including the elevator, but such tower-type apartments are Since the plane requires a required length in both the vertical and horizontal directions, a sufficient site area and shape corresponding to the length are required, and it is difficult to construct a relatively small site.
Therefore, there is a demand for a compact flat housing that can be constructed as a high-rise or ultra-high-rise building in a limited and narrow site.

Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-64654) states that “a structure of a building having a planar shape that is long in the direction of the beam, and a core portion is provided on the side of the building, and each floor has an earthquake resistance along the direction between the beams. A large number of walls are arranged side by side at predetermined intervals so that the seismic walls on each floor are connected vertically, and when a series of seismic walls that continue above and below and the frame of the core part are relatively displaced in the vertical direction, they operate. The structure of the building is characterized by being connected by a damper. ”(Claim 3) is disclosed, and in the same document,“ the doorway wall 1 (seismic wall) having a predetermined span and the core portion are described for the building of the second embodiment. The damper 8 is provided between the housing 10 and the housing 10 ”(0012),“ that is, this building is provided with a core portion 10 connected to the common hallway 3 as shown in FIG. And elevator installed The core part 10 is structurally independent from the residential building part (the dwelling unit 2 and the common corridor 3), and the door wall 1 facing the core part 10 is a pillar 9 on each floor as shown in FIG. Is connected by a damper 8 to a connecting beam 10a on the shared corridor side of the core portion 10 "(0013).
The invention described in this document is characterized in that the earthquake-resistant wall and the core part are connected by a damper, and the structure of the core part is a general form in which a staircase and an elevator are installed in the housing. is there. In addition, a compact plan shape can be configured by a simple frame, and it does not solve the problem of providing an apartment house that can be constructed as a high-rise or super-high-rise building in a limited narrow site.

  The preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the same reference numerals are used for the same elements in the drawings, and description thereof may be omitted as appropriate.

  FIG. 1 is a perspective view schematically showing an apartment house according to the embodiment, FIG. 2 is a plan view of a reference floor of the apartment house (building) according to the embodiment, and FIGS. 3 and 4 show a framework of the apartment house according to the embodiment. FIG. 5 is a plan view of another floor of the apartment house according to the embodiment.

  First, a description will be given with reference to FIGS. A building 1 configured as a super high-rise apartment building includes a balcony-side ramen construction surface 5 and a shared corridor-side ramen construction surface 2 that form a crossing direction. The balcony-side ramen construction surface 5 is constructed by columns 6 and beams 7 standing on the foundation, and the common corridor-side ramen construction surface 2 is constructed by columns 3 and beams 4 standing on the foundation. ing. The illustrated one has a form having 5 spans in the column direction. A ramen construction surface 8 is provided on the inner side of the shared corridor side ramen construction surface 2 in parallel with the ramen construction surface 2, but this ramen construction surface 8 may be omitted. The beam-to-beam direction of the building 1 is constituted by a beam 9 or a seismic wall that connects the columns of the respective structural surfaces of the balcony-side ramen structural surface 5 and the shared corridor-side ramen structural surface 2.

  The building 1 is configured as a plate-like house in which a plurality of dwelling units 11a, 11b, 11c, 11d, and 11e are arranged in the column direction. In the example shown in the figure, the boundary wall is provided at the same position as the beam 9 in the inter-beam direction in accordance with the number of spans in the column direction (5). May be.

  Two projecting frame parts 20 and 20 are projected from the common corridor side ramen structural surface 2 in the beam-to-beam direction and toward the outside, and spaced from both ends 1a and 1b in the direction of the beam of the building 1 And it connects to the common hallway side ramen construction surface 2 so that the internal area | region 21 (refer FIG. 3) enclosed by the common hallway side ramen construction surface 2 and the overhanging frame structure 20 may be extended and formed in the up-down direction. Is provided.

An elevator 31 is disposed as a lifting device in a “part” of the internal area 21 surrounded by the common hall side ramen structure surface 2 and the overhanging frame section 20, and in the internal area 21, the building 1 The ventilating part 25 which communicates in the up-and-down direction and from which the lighting to the dwelling unit parts 11b and 11d facing the overhanging frame part 20 is obtained is provided.
The vent 25 is a space that does not have a floor and penetrates the floor in the vertical direction, and communicates from the lower floor to the top floor of the building. A hollow daylighting space is formed. The frame portion surrounding the blowout portion 25 of the overhang frame portion 20 is usually not formed with a wall portion in order to obtain sufficient lighting from the side surface and further ventilation. The uppermost part of the blowout part 25 is normally in an open state, but a roof (transparent roof) or the like may be provided.

  In the internal region 21, the elevator 31, which is an elevating equipment, has one extension surface 24a in the direction between the building beams of the extension frame portion 20 (in the illustrated example, the end portion in the column direction as viewed from each extension frame portion 20). 1a, 1b side: Wife surface side). By forming the elevator 31 in the internal region 21 of the overhanging frame portion 20 using the framework of the overhanging frame portion 20 that is a part of the structural frame and is also strong as a support, formation of a fire wall and an attached room Is simple and reliable.

  A staircase 32 that is an elevating equipment is provided on the outside of the one frame surface 24a in the direction between the beams of the overhang frame portion 20, and the elevator 31 and the staircase 32 are arranged so as to sandwich the one frame surface 24a. Each core part 30 and 30 which consists of is formed. That is, the entire core portion 30 including the elevator 31 and the staircase 32 is not stored in the inner region of the overhanging frame portion 20, and the entire core portion 32 is formed such that the staircase 32 protrudes outside the overhanging frame portion 20. Are shifted by a half span. The staircase 32 is configured as an external staircase (outdoor escape staircase), and its construction is simple. The staircase 32 may be configured as a special evacuation staircase in the case of a building having 15 floors or more. The core parts 30 and 30 are connected to the common hallways 12a and 12b (scattered hatching parts), respectively.

  As shown in FIG. 3, the overhanging frame portion 20 is made up of columns 22 and 22 that are opposed to each other at a distance corresponding to one span among a plurality of spans that form the shared corridor side ramen structure surface 2. The beam 23 connecting the pillars, the beam 22, 22 and the beam 24 connecting the common corridor side ramen construction surface 2 are formed, forming a part of the frame structure of the building 1 and having a U-shape in plan view. Are connected to one span (columns forming one span) of the plurality of spans forming the shared corridor side ramen construction surface 2. The overhanging frame portion 20 includes a base portion on which a pillar 22 is erected, and is configured as a framework that is structurally integrated with the building 1. The frame surfaces 24a and 24b arranged opposite to each other in the beam-to-beam direction (vertical direction in the figure) of the overhanging frame portion 20 are linear with the frame surface in the beam-to-beam direction of the building body (the frame portion excluding the overhanging frame portion 20). To form a structurally integrated frame surface. The structural type of the overhanging frame portion 20 is selected in accordance with the structure of the building body such as reinforced concrete or steel reinforced concrete.

Also, in the building 1, one unit is formed by connecting one overhanging frame portion 20 per 2 to 4 consecutive spans among a plurality of spans forming the shared corridor side ramen structural surface 2. Are connected in the column direction. The building shown in the figure is a ramen structure having five spans in the direction of the beam, one unit with one overhanging frame part 20 connected to two consecutive spans, and one overhanging frame part 20 per three consecutive spans. It can be understood that one unit connected to is connected in the column direction.
In addition, the common hallway side ramen construction surface 2 is provided with a pair of overhanging construction parts 20, 20 provided to connect to the second span one span from both ends 1 a, 1 b of the building in the crossing direction. It is a form and a simple and balanced frame.

  The present invention is particularly suitable for constructing a compact and well-balanced planar high-rise building in which the crossing direction is formed in 4 to 8 spans. By combining two units with one unit connected, an apartment house with high privacy of 2 to 4 units / elevator (1 unit) can be obtained.

The tower ratio (aspect ratio) of the building = the height of the building (H) / the width of the building. In the present invention, there are two lengths: Y1 in the beam-to-beam direction of the building and Y2 in the depth of the overhanging frame (see FIG. 4). About the tower ratio of such buildings,
α1 = H / Y1,
α2 = H / (Y1 + Y2)
Let β = Y1 / (Y1 + Y2).
Thus, for example, in a 30-story apartment house, the height of the building (H) = 100 m, Y1 = 15.5 m, and Y2 = 6.0 m are assumed. Then
α1 = 100 / 15.5 = 6.45,
α2 = 100 / (15.5 + 6) = 4.65,
β = 15.5 / (15.5 + 6) = 0.72, and the building tower ratio is substantially reduced from 6.45 to 4.65, which facilitates the structural design of the building.
With the value of β, when α1 = 4 to 6, it is reduced to α2 = α1 × β = (2.88 to 4.32). Even when α1 exceeds 6 and α1 = 6 to 8, it falls within the range of α2 = 4.32 to 5.76. Usually, for buildings according to the present invention, 0.6 ≦ β ≦ 0.75 and α1 = 4 to 8, preferably α1 = 6 to 8, the structural design can be achieved even in the case of a very high-rise building. It's easy to do.

A planar layout of the building 1 will be described with reference to FIG.
A plurality of dwelling units 11a, 11b, 11c, 11d, and 11e are arranged between the balcony-side ramen construction surface 5 and the common corridor-side ramen construction surface 2 in the row direction, and the balcony-side ramen construction surface 5 that is normally located on the south side. A balcony 14 which is a dedicated part of each dwelling unit is provided along the line. Moreover, the balcony 14a is provided along the end portions 1a, 1b: the wife surface in the direction of the line in succession to the balcony 14. Furthermore, the balcony 14b is provided along the shared hallway side ramen construction surface 2 continuously to the balcony 14a. Therefore, the dwelling units 11a and 11e located on the wife's face have a form in which the balconies 14, 14a and 14b are provided so as to surround three sides excluding the direction of the adjacent dwelling unit, and have excellent lighting and openness. It is a high-value-added dwelling unit. The balcony 14 b may be connected to the core unit 30. By doing so, an evacuation route that can reach both cores by horizontally moving each floor by using a balcony is secured, and the building becomes safe in the event of a disaster.

  On the shared hall side ramen construction surface 2 side, a plurality of shared hallways (12a, 12b) for connecting the elevator 31 located in the core part 30 and the dwelling units are provided independently. That is, the dwelling units 11b and 11c located in the middle part between the beams are provided with balconies (which can also be configured as living rooms) 14d and 14e, which are dedicated portions of the dwelling unit, along the shared corridor side ramen construction surface 2. The shared hallways are divided by the balconies 14d and 14e, and a plurality of independent shared hallways 12a and 12b are provided. The core part 30 on the left side of the figure is provided with a common hallway 12a that communicates with the two dwelling units 11a and 11b, and the core part 30 on the right side of the figure is provided with a common hallway 12b that communicates with the three dwelling units 11c, 11d, and 11e. Yes. Thereby, one elevator is secured for a relatively small number of dwelling units, and the dwelling units 11b and 11c do not allow residents of other dwelling units to come and go through the common corridor. For this reason, an environment with high privacy can be obtained.

Further, the dwelling part 25 provided in the overhanging frame part 20 brings the daylight to the balcony 14d to the dwelling unit 11b facing the overhanging frame part 20, and faces the other overhanging frame part 20 The dwelling unit 11d is provided with lighting through the shared corridor 12b. Therefore, also in the dwelling unit parts 11b and 11d facing the extended frame part 20, a living room can be arranged on the shared corridor side.
In the dwelling unit 11b facing the overhanging frame, the balcony 14d connected to the living room (or may be configured as a part of the living room) directly faces the blowout part 25 without going through the common hallway. Since it is arranged, it becomes a dwelling unit with high privacy and excellent lighting and openness.

  An entrance porch 11d-a is provided at the entrance of the dwelling unit 11d. A buffer zone is provided at the entrance to the common hallway 12b to ensure privacy.

Further, in this building 1, in addition to the floor (FIG. 2) in which a plurality of shared corridors are provided independently as described above, as shown in FIG. The common corridor 15 connects the elevators 31 and 31 located in the core portions 30 and 30 to each other. In the same floor, each elevator 31, 31 located in each core part 30, 30 can be selectively used from all the dwelling units. The common hallway 15 is connected to the core portions 30 and 30 and also communicates with the stairs 32 and 32 located in the core portion. Therefore, residents of the floor (the floor in FIG. 2) where a plurality of shared corridors are provided independently use the staircase 32 even when one elevator used daily is stopped for inspection or the like. By moving to the floor (the floor in FIG. 5) where the shared corridor 15 that connects the plurality of core parts 30 and 30 is provided, it is possible to walk the shared corridor 15 on the moved floor and use another elevator 31. As a result, there is no inconvenience that the elevator cannot be used.
In addition, normally, as described above, a plurality of shared corridors and a plurality of independently provided floors are continuously stacked in a plurality of floors. It is preferable to arrange the floor provided with the shared corridor 15 that connects the core portions 30 and 30 because many dwelling units with excellent privacy can be provided. For example, a plurality of shared corridors are provided on four independent floors, and a floor provided with a common corridor 15 that connects a plurality of core sections 30 and 30 is arranged on each fourth floor. To do.

  FIG. 6 shows an aspect of a floor in which a plurality of shared corridors are provided independently as described above, but the floor shown in FIG. 2 and its layout are reversed left and right. As described above, this building 1 has 5 spans (odd spans), and when one dwelling unit is arranged for each span, on a floor where a plurality of shared corridors are provided independently, 1 elevator / 2 dwelling units and 1 It becomes the usage form of an elevator called elevator / 3 dwelling unit. For this reason, the usage amount of each elevator will be biased. However, by appropriately stacking the floor shown in FIG. 2 and the floor shown in FIG. 6, the usage amount of each elevator is averaged, and it is avoided that the number of users is biased. The operation amount of the elevator can be averaged.
