  FIG. 3 is a diagram illustrating a dwelling unit division (plan plan) of the apartment house 10. As shown in this figure, in the housing complex 10, a corridor 13 is defined on one side of the spanning direction of the plurality of dwelling units 12 arranged in the direction of the line, and a balcony 15 is defined on the other side. In addition, a watering zone 12A in which a kitchen, a unit bath, and the like are installed is defined at the center of each dwelling unit 12 in the spanning direction, and living room zones 12B and 12C are partitioned on both sides in the spanning direction.

  Here, in each floor, the surrounding zones 12A of the plurality of dwelling units 12 are arranged in a line in the column direction, and the wall pillar 20 is provided between the surrounding zones 12A of the adjacent dwelling units 12. That is, the plurality of wall pillars 20 are arranged in a line in the column direction. Further, the positions in the span direction between the wall column 30 and the both ends in the width direction of the wall column 20 coincide with each other.

  FIG. 4 is a schematic plan view of the dwelling unit 12. As shown in this figure, the wall pillar 20 is provided between RC pillars 22 built at both ends in the spanning direction of the water circulation zone 12A and a pair of pillars 22 arranged in the spanning direction. RC earthquake-resistant wall 24 is provided.

  Here, the earthquake-resistant wall 24 of the wall pillar 20 is a multi-layer earthquake-resistant wall extending over a plurality of floors (for example, from the lowest floor to the highest floor as shown in FIG. 1). On the other hand, the dry sound insulation wall 38 is a wall made of gypsum board, glass wool or the like constructed for each of the living room zones 12B and 12C of each dwelling unit 12, and is not a seismic wall and can be removed.

  FIG. 5 is a perspective view illustrating some of the dwelling units 12 of the apartment house 10. As shown in this figure, the slab 40 in the water circulation zone 12A is set to be lower than the slabs 42 in the living room zones 12B and 12C, and is a space formed by the height difference between the floor of the kitchen or bath and the slab 40. In addition, drainage facilities such as drain pipes are installed. Here, a beam 26 is built between the columns 22 of the wall columns 20 arranged in the column direction. The beam 26 is provided at a step portion between the slab 40 and the slab 42.

  FIG. 6 is a diagram illustrating a section on the lowermost floor (first floor) of the apartment house 10. As shown in this figure, on the lowest floor of the apartment house 10, in addition to the dwelling unit 12, a common section 19 such as an entrance is provided. Here, on the upper floor of the common section 19, three dwelling units 12 arranged in the column direction are provided, and the wall pillar 20 that continues from the lowest floor to the top floor also exists in the common section 19. On the other hand, the dry sound insulation wall 38 is not provided in the shared part 19.

  In addition, on one side of the common part 19 in the span direction, a passage 19A that can travel in the direction of the crossing is formed between the wall column 20 and the pillar 14, whereas the other side of the common part 19 in the span direction On the side, a zone 19B such as a toilet or office is defined between the wall pillar 20 and the pillar 14.

  Here, in the apartment house 10 according to the present embodiment, the wall column 20 is formed by configuring only a part (central portion) of the boundary wall direction of the doorway wall with the wall column 20 which is a multi-layer earthquake-resistant wall. Even when the common part 19 on the lowest floor is continued, a passage 19A in the column direction can be formed, and the common part 19 can be made a space that can travel in the column direction. Accordingly, it is possible to configure the apartment house 10 as a building that is not a piloti-type building and has excellent seismic performance, and to increase the degree of freedom in the floor plan of the lowest floor.

  FIG. 7 is a plan view showing the frame 11 of the apartment house 10. As shown in this figure, the frame 11 of the apartment house 10 is formed with four planes A1 to A4 that are parallel to the direction of the beam. The composition plane A1 is composed of the columns 14 and beams 16 on the corridor 13 side, and the composition surface A4 is composed of the columns 14 and beams 16 on the balcony 15 side. In addition, the construction surface A2 is composed of columns 22 and beams 26 between the water circulation zone 12A and the living room zone 12C on the corridor 13 side, and the construction surface A3 is composed of the water circulation zone 12A and the living room zone 12B on the balcony 15 side. It is comprised by the pillar 22 and the beam 26 between them.

  Here, in the housing complex 10 according to the present embodiment, not only the two structural surfaces A1 and A4 on the corridor 13 side and the balcony 15 side, but also the two structural surfaces A2 and A3 between them, the row direction (X in the figure). Direction) seismic force. As a result, the holding horizontal strength required for the pillar 14 and the beam 16 constituting the two structural surfaces A1 and A4 on the corridor 13 side and the balcony 15 side is reduced, so the pillars 14 constituting the two structural surfaces A1 and A4, The cross-sectional dimension of the beam 16 can be reduced, and thus the indoor space of the dwelling unit 12 can be expanded.

  In addition, the seismic force in the span direction (Y direction in the figure) is borne by the plurality of structural surfaces B1 and B2 including the wall column 20 and the beam 28. In the structural surfaces B1 and B2, the entire span direction is Since only a part (central part) is made up of the wall pillars 20 that are multi-layer earthquake-resistant walls, the collapsed form of the earthquake-resistant wall in the doorway tends to be a bending yielding type. Holding horizontal strength can be reduced. Therefore, the thickness of the wall pillar 20 which is a seismic wall at the door boundary can be reduced, and thus the indoor space of the dwelling unit 12 can be expanded.

  In addition, in the construction plane B1, from the bottom floor to the top floor, only a part (central part) is composed of the wall pillar 20 which is a multi-layer earthquake-resistant wall instead of the entire span direction, but in the construction plane B2, For the lowest floor and the top floor, the entire space in the span direction is composed of earthquake-resistant walls, and for the floor between the bottom floor and the top floor, only part of the span direction is composed of wall pillars 20 doing. This point will be described later.

  The wall pillar 20 is composed of a pair of pillars 22 and a seismic wall 24 between them, and no beam connecting the pair of pillars 22 is provided. For this reason, since the beam does not protrude from the door boundary wall in the water circulation zone 12A, equipment such as a unit bath can be installed close to the door boundary wall, so that the space in the dwelling unit 12 is increased. It can be used effectively.

  In addition, since the beam 26 is installed on the step portions of the slabs 40 and 42 to form the frame structure of the beam 26 and the column 22, the construction surface supporting the slabs 40 and 42 can be configured by the columns 22 and 26. Therefore, the bending strength required for the slabs 40 and 42 can be reduced, and thus the thickness of the slabs 40 and 42 can be reduced.

  Further, in the water-circulating zone 12A, it is necessary to make the floor height lower than the living room zones 12B and 12C for installing the drainage equipment, and the beams 26 are provided at the step portions of the slabs 40 and 42 generated thereby. Thus, the structural surfaces A2 and A3 can be formed without sacrificing the indoor space of the dwelling unit 12.

  Here, as the length of the multistory earthquake-resistant wall in the spanning direction (direction orthogonal to the arrangement direction of the dwelling units) becomes longer, the drying shrinkage of the concrete increases, and cracking tends to occur in the concrete. And when the crack of the concrete of a door wall occurs, the sound insulation performance between dwelling units will fall, or it will interfere with the finish of a door wall. On the other hand, in the apartment house 10 according to the present embodiment, the wall column 20 that is a multistory earthquake-resistant wall is configured only in a part (central part) rather than the whole of the spanning direction of the door-to-wall walls. The length in the spanning direction is made shorter. Moreover, the seismic wall 24 is restrained by the pillars 22 from both sides in the spanning direction. As a result, the drying shrinkage of the concrete can be suppressed and cracking can be prevented from occurring in the concrete, so that sound insulation performance between the dwelling units can be secured and the finishing of the doorway walls should not be hindered. Can do.

  FIG. 8 is an axis diagram of the composition planes A2 and A3. As shown in this figure, wall pillars 30 and wall beams 32 are provided on both sides of the planes of construction A2 and A3 in the column direction (X direction in the figure). The wall pillar 30 extends from the lowest floor to the rooftop along the outer wall. Moreover, the wall pillar 30 is provided so that a width | variety may spread with respect to the column direction.

  Further, the wall beam 32 is provided on the corner dwelling unit in parallel to the column direction, one end of the column direction is coupled to the upper end of the wall column 30, and the other end is connected to the upper end of the column 22 of the wall column 20. Are combined. Here, the wall-shaped pillar 30, the wall beam 32, and the pillar 22 constitute a gate-shaped frame 44, and the frame 44 bears the seismic force in the direction of the girder, thereby bearing the structural surfaces A1 to A4. Seismic force in the direction of girder is reduced.

  Here, in general, in middle- and high-rise apartments, the higher the height, the greater the earthquake vibration and the greater the seismic force, so the cross-sectional dimensions of the columns and beams are set larger. The room space is narrowed by protruding into the room. Here, in the apartment house 10 according to the present embodiment, there are beams 26 constituting the planes A2 and A3, but when the beams 26 protrude into the indoor space, the floor space is increased by raising the floor height. It is necessary to ensure the spread.

  On the other hand, in the housing complex 10 according to the present embodiment, the seismic force in the direction of the girders borne by the structural surfaces A1 to A4 is reduced by the frame 44, and therefore the columns 14 and 22 constituting the structural surfaces A1 to A4. The cross-sectional dimensions of the beams 16 and 26 can be set smaller, and the cross-sectional dimensions of the columns 14 and 22 of the dwelling unit 12 and the beams 16 and 26 can also be set smaller. Therefore, it is possible to suppress the pillars 14 and 22 and the beams 16 and 26 from protruding into the indoor space in the dwelling unit 12, and to ensure the expansion of the indoor space. Moreover, about the dwelling unit 12, the expansion of indoor space can be ensured, without raising a floor height. Moreover, since the cross-sectional dimensions of the columns 14 and 22 and the beams 16 and 26 can be set smaller, these costs can be reduced.

  Further, in the housing complex 10 according to the present embodiment, the wall beam 32 is coupled to the upper end of the wall column 20, and the wall column 20 that is a multi-layer earthquake resistant wall constitutes the frame 44. The burden of seismic force in the direction is effectively increased. Therefore, it is possible to further reduce the burden of seismic force in the column direction due to the planes A1 to A4, and to further reduce the cross-sectional dimensions of the columns 14 and beams 16 and 26 constituting the planes A1 to A4.

  Further, in the apartment house 10 according to the present embodiment, the wall pillar 30 is provided along the outer wall, and the wall beam 32 is provided on the roof, so that they are not protruded into the indoor space of the dwelling unit 12. It is possible to reduce the burden of seismic force in the column direction by the planes A1 to A4, and it is possible to further reduce the cross-sectional dimensions of the columns 14 and the beams 16 and 26 constituting the composition planes A1 to A4. Therefore, the expansion of the indoor space of the dwelling unit 12 can be ensured.

  FIG. 9 is an axis diagram of the composition plane B2. As shown in this figure, in the floor between the lowermost floor (first floor) and the uppermost floor, only the central part of the doorway wall in the span direction is composed of wall pillars 20 that are multi-layer earthquake resistant walls. On the other hand, on the lowermost floor and the uppermost floor, the entire span of the doorway walls is composed of earthquake-resistant walls 46 and 48, respectively.

  Here, on the lowest floor and the top floor, the surface B2 constitutes the boundary wall of the dwelling unit 12, and there is a common space 19 on the bottom floor, a parking lot, etc. Not located. That is, the floor plan of the lowermost floor and the uppermost floor is not obstructed by the earthquake resistant walls 46 and 48 of the structural surface B2.

  FIG. 10 is a conceptual diagram of bending deformation of the wall column 20. As shown in the figure, the wall column 20 has a width direction (in-plane direction) shorter than the width direction dimension of the doorway wall and has a shape elongated in the height direction. Direction) horizontal force (seismic force, wind load, etc.) acts, the bending deformation in the in-plane direction increases. For this reason, in the upper floor portion of the wall column 20, the load of horizontal force is reduced, and the load of horizontal force by the pillar 14 and the beam 28 on the side of the corridor 13 and the balcony 15 is increased. It is necessary to set the cross-sectional dimension of the beam 28 to be large.

  On the other hand, as shown in FIG. 11, in the housing complex 10 according to the present embodiment, the seismic walls 46 and 48 that continue from the pillar 14 on the corridor 13 side to the pillar 14 on the balcony 15 side on the top floor and the bottom floor. By providing, the bending deformation in the in-plane direction of the wall column 20 can be suppressed. That is, the axial force generated in the wall column 20 when the wall column 20 is bent and deformed acts on the column 14 on the corridor 13 side or the balcony 15 side, and the column 14 resists this axial force. The bending deformation in the in-plane direction is suppressed. Further, by suppressing the bending deformation in the in-plane direction of the wall column 20, the burden of horizontal force on the upper floor portion of the wall column 20 increases, and the columns 14 on the corridor 13 side and the balcony 15 side of the upper floor, The burden of horizontal force by the beam 28 is reduced. As a result, the cross-sectional dimensions of the upper-layer pillars 14 and beams 28 can be set smaller. Therefore, in the dwelling unit 12 on the upper floor, the pillars 14 and the beams 28 on the corridor 13 side and the balcony 15 side can be prevented from projecting into the indoor space, and the expansion of the indoor space can be ensured. In addition, since the cross-sectional dimensions of the column 14 and the beam 28 can be set smaller, the cost of the column 14 and the beam 28 can be reduced.

By bearing the force, the seismic force in the direction of the girder borne by the planes A1 to A4 is reduced. Therefore, the cross-sectional dimensions of the columns 14 and 22 and the beams 16 and 26 constituting the composition planes A1 to A4 can be set smaller, and the cross-sectional dimensions of the columns 14 and 22 and the beams 16 and 26 of the dwelling unit 12 can be set smaller.

  According to the apartment house which concerns on this embodiment, the burden of the horizontal force in the upper floor part of the wall pillar 20 is large by suppressing the bending deformation of the in-plane direction of the wall pillar 20 similarly to the above-mentioned embodiment. Thus, the burden of horizontal force due to the pillars 14 and beams 28 on the corridor 13 side and the balcony 15 side on the upper floor is reduced. Therefore, the cross-sectional dimensions of the columns 14 and beams 28 on the corridor 13 side and the balcony 15 side on the upper floor can be set smaller.

  FIG. 14 is an axis diagram of the planes A1 and A4 of the frame 311 of the apartment house according to another embodiment.
