Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building structure of an apartment house in which a large number of dwelling units having balconies in one direction are arranged side by side in the vertical direction and the horizontal direction with each balcony facing in the same direction.
[0002]
[Prior art]
As a building structure of such an apartment house, the entire building has a flat slab structure without beams, and an unbonded steel brace is arranged on a floor that requires rigidity against a horizontal force such as an earthquake (for example, see Patent Document 1). ) And those using a super slab that forms a ramen frame on a floor that requires rigidity (for example, see Patent Document 2).
In addition, in each dwelling unit having a balcony, a structure in which a frame structure in the row direction on the balcony side and the opposite side of the balcony is a ramen structure, and a frame structure in a beam-to-beam direction is a wall structure is also known (for example, see Patent Document 3) .

[Problems to be solved by the invention]
However, the building structures disclosed in Patent Documents 1 and 2 require an unbonded steel brace or a super slab having a special structure on a specific floor, so that the construction of the building may become complicated, and many For example, if each dwelling unit has a balcony, the view from the balcony is inferior to the view from the other floors. There is also a possibility to do.
Further, in the building structure disclosed in Patent Document 3, since the frame on the balcony side is a ramen structure having beams, the beam shape protrudes from the ceiling surface of each dwelling unit, and the protruding beam shape impedes the feeling of opening on the balcony side. There is a drawback that visibility is worsened.
[0005]
The present invention pays attention to such a conventional problem, and its purpose is to make the structure uniform among a large number of dwelling units to avoid complication of construction, and for example, limited floor height ( For example, within 3 m), in any dwelling unit, it is to provide a building structure of an apartment house that can maintain a good view from a balcony and can sufficiently cope with an earthquake or the like.
[0006]
[Means for Solving the Problems]
The characteristic configuration of the invention of claim 1 is a building structure of an apartment house in which a large number of dwelling units having balconies in one direction are arranged in parallel in the vertical direction and the horizontal direction with each balcony facing in the same direction, In each of a large number of dwelling units, the frame in the row direction on the balcony side is configured by a flat slab structure without beams, and the frame in the row direction on the side opposite to the balcony is a beam having the same beam width as the wall thickness in the wall. The frame structure between the beams that divides each dwelling unit is composed of a seismic wall, and the frame structure in the direction of the beam opposite to the balcony and the seismic wall in the direction between the beams that partitions each dwelling unit. The horizontal rigidity and earthquake resistance required for each dwelling unit are ensured by this frame.
[0007]
According to the characteristic configuration of the invention of claim 1, in each of a large number of dwelling units having a balcony in one direction, the frame structure in the row direction on the balcony side is constituted by a flat slab structure without a beam. However, in a limited floor height, for example, the beam shape does not protrude from the ceiling on the balcony side. Therefore, the field of view can be maintained well by opening the balcony side.
The frame in the direction opposite to the balcony is a ramen structure with a beam with the same beam width as the wall thickness in the wall, and the frame in the beam direction that partitions each dwelling unit is composed of a seismic wall. Therefore, the beams are not exposed on the opposite side of the balcony, and each dwelling unit has a ramen structure frame in the crossing direction opposite to the balcony and a seismic wall in the direction between the beams separating each dwelling unit. Necessary horizontal rigidity and earthquake resistance are ensured, and the construction of each dwelling unit is made uniform, thereby avoiding complicated construction.
[0008]
The characteristic configuration of the invention of claim 2 is that a common passage is provided outside the frame on the opposite side of the balcony, and the entire building of the apartment house is supported by a seismic isolation device .
[0009]
According to the characteristic configuration of the invention of claim 2, since the common passage is provided outside the frame opposite to the balcony, that is, outside the frame structure incorporating the beam in the wall, sound insulation from the common passage is also possible. As a result, it is possible to secure a quiet and open dwelling space.
[0011]
Furthermore, according to the characteristic configuration of the invention of claim 2, since the entire building of the apartment house is supported by the seismic isolation device, the seismic resistance is further improved by reducing the seismic force by the seismic isolation device.
According to a third aspect of the present invention, each dwelling unit has a balcony side wall column at both ends on the balcony side, and the balcony protrudes outward from the balcony side wall column.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the building structure of an apartment house according to the present invention will be described with reference to the drawings.
This building structure is implemented in an apartment house such as a condominium or a resort hotel. As shown in FIG. 1, for example, a flat slab 1 made of flat reinforced concrete having a thickness of about 250 to 350 mm arranged in multiple layers, and its A plurality of dwelling units 5 including a plurality of balcony side wall columns 2 and corridor side wall columns 3 supporting the flat slab 1 and having a balcony 4 in one direction are arranged in the vertical direction with each balcony 4 facing the same direction, for example, the south side. A corridor 6 which is a common passage is provided on the north side opposite to the balcony 4.
[0013]
As shown in FIGS. 2 to 4, the frame on the balcony 4 side in the row direction X of each dwelling unit 5 is a flat slab structure without beams, for example, a flat slab 1 directly by a balcony side wall column 2 having a thickness of about 150 mm. It is comprised by the flat slab structure A to support, and the balcony 4 protrudes outside the balcony side wall pillar 2. FIG. The frame on the side of the corridor 6 is configured, for example, in a ramen structure B composed of a corridor side wall column 3 and a beam 7 having a thickness of about 220 mm, and a beam 7 having the same beam width as the wall thickness is built in the corridor side wall 8 made of reinforced concrete. The hallway 6 is disposed outside the hallway side wall 8.
In the inter-beam direction Y of each dwelling unit 5, the door frame that divides each dwelling unit 5 is composed of, for example, a reinforced concrete seismic wall C having a thickness of about 180 mm, and the ramen structure in the row direction X opposite to the balcony 4. The horizontal rigidity and the earthquake resistance necessary for each dwelling unit 5 are secured by the frame of the earthquake resistant wall C in the inter-beam direction Y that partitions the B frame and each dwelling unit 5. The entire building of the apartment house having such a configuration is supported by a high-damping laminated rubber support type seismic isolation device 9 interposed below each balcony side wall column 2 and corridor side wall column 3.
[0014]
[Another embodiment]
(1) In the previous embodiment, an example in which the flat slab 1, the hallway side wall 8, and the earthquake resistant wall C are made of reinforced concrete has been shown. However, regarding the flat slab 1, the hallway side wall 8, and the earthquake resistant wall C, For example, precast concrete produced in a factory can be used in addition to the reinforced concrete produced on site.
[0015]
(2) In the previous embodiment, a high damping laminated rubber bearing type was shown as an example of the seismic isolation device 9, but it is possible to use various types of seismic isolation devices such as a sliding bearing type and a spring bearing type. it can.
