  However, on each floor, there are seismic walls 57 at intervals in the girder direction, and the seismic walls 57 extend from one side of the ramen structures 51 and 52 to the other in the beam direction. Design flexibility is limited. For example, each dwelling unit is limited to a space between two adjacent seismic walls 57. This also applies to Patent Document 1. Patent Document 2 describes that the beam on the balcony side is formed flat.

  Accordingly, an object of the present invention is to provide a building that can increase the degree of design freedom of the floor plan without adversely affecting the seismic strength of the building, and as a result, can add value.

  In the present embodiment, as shown in FIG. 4, the building 10 includes a lower floor structure 3 for configuring each floor below the top floor (hereinafter simply referred to as a lower floor) and a top floor for configuring the top floor. And a side frame 5. In FIG. 4, reference numeral 12 denotes a slab.

  As shown in FIG. 3 (A), the lower floor frame 3 has two ramen structures 7 and 9 provided apart from each other in the beam-to-beam direction and a gap in the beam direction between these ramen structures 7 and 9. And a plurality of beam-attached structures 11 extending in the inter-beam direction.

  As shown in FIG. 3 (B), the uppermost frame 5 is spaced apart in the beam direction between two ramen structures 7 and 9 that are provided apart in the beam-to-beam direction, and between these ramen structures 7 and 9. And a plurality of (for example, three or more) structures with beams 11 and 14 extending in the inter-beam direction.

  In the uppermost frame 5, each of the structures with beams 11, 14 has a beam 13 that extends in the inter-beam direction from one of the two ramen structures 7, 9 to the other. 14, at least one of the structures with beams 14 (for example, the structure with beams 14 located in the middle of the beam direction) has a wall column 15 that supports the beam 13 of the structure with beams 14 from below. .

  The upper end portion of each wall column 15 is coupled to a beam 13 supported from below by the wall column 15. The lower end portion of each wall column 15 is coupled (joined) to the beam 13 on the floor one level lower than the floor (here, the uppermost floor) of the wall column 15.

  Also on the uppermost floor, the upper end portion of the wall column 15 is coupled to a beam 13 extending in the beam-to-beam direction from one of the two frame structures 7 and 9 to the other. Each of these two ramen structures 7 and 9 constitutes the uppermost floor and is located above the uppermost floor. Each of these two ramen structures 7 and 9 has a plurality of pillars 17 spaced apart in the spar direction and a plurality of beams 19 extending in the spar direction. The ramen structure is formed by extending between the columns 17 adjacent to each other and having both ends coupled to the columns 17. The dimension in the girder direction of the beam 13 to which the upper end portion of the wall pillar 15 on the top floor is coupled is the same as the dimension in the girder direction of the wall pillar 15.

  FIG. 5 shows a wall column 15 and a bar arrangement structure 16 of the upper and lower beams 13 to which the upper end portion and the lower end portion of the wall column 15 are respectively coupled. FIG. 5A is a view as seen from the girder direction, and FIG. 5B is a view taken along the line BB in FIG. 5A (that is, a view as seen from the direction between the beams). In the example of FIG. 5, the reinforcing bar structure 16 includes at least a plurality of first reinforcing bars 16a, a plurality of second reinforcing bars 16b, a plurality of third reinforcing bars 16c, and a plurality of fourth reinforcing bars 16d. The plurality of first reinforcing bars 16 a extend in the vertical direction from the inside of the lower beam 13 through the inside of the wall column 15 to the inside of the upper beam 13. Each second reinforcing bar 16b extends so as to surround a bundle of a plurality of first reinforcing bars 16a. The plurality of second reinforcing bars 16b are arranged at intervals in the vertical direction. A part of these second reinforcing bars 16 b is also provided in the upper beam 13 and the lower beam 13. In the upper beam 13, a plurality of third reinforcing bars 16 c extend in the longitudinal direction of the beam 13 (inter-beam direction). Inside the lower beam 13, a plurality of third reinforcing bars 16 c extend in the longitudinal direction (inter-beam direction) of the beam 13. Inside the upper beam 13, each fourth reinforcing bar 16 d extends so as to surround a bundle of a plurality of third reinforcing bars 16 c, and these fourth reinforcing bars 16 d are arranged at intervals in the longitudinal direction of the beam 13. ing. Inside the lower beam 13, each fourth reinforcing bar 16 d extends so as to surround a bundle of a plurality of third reinforcing bars 16 c, and these fourth reinforcing bars 16 d are arranged at intervals in the longitudinal direction of the beam 13. Has been. The plurality of first reinforcing bars 16 a, the plurality of second reinforcing bars 16 b, the plurality of third reinforcing bars 16 c, and the plurality of fourth reinforcing bars 16 d are embedded in the concrete 16 e that forms the wall columns 15 and the beams 13.

  It is assumed that the distance between the two third reinforcing bars 16c separated in the direction of the girders, the dimension of the entire fourth reinforcing bar 16d, and the dimension of the beam 13 including the concrete 16e are determined. In this case, as shown in FIG. 5, the first reinforcing bars 16a (the main bars of the wall column 15) are arranged inside the two third reinforcing bars 16c (the main bars of the beam 13) that are separated in the spar direction. Thereby, the digit direction dimension of the 2nd reinforcing bar 16b whole can be made smaller than the digit direction dimension of the 4th reinforcing bar 16d whole. Therefore, when the beam 13 and the wall column 15 are formed of concrete 16e, the wall column 15 can be prevented from protruding from the beam 13. For example, as shown in FIG. 5B, the distance L1 from the end of the second reinforcing bar 16b to the outer surface of the concrete 16e is greater than the distance L2 from the end of the fourth reinforcing bar 16d to the outer surface of the concrete 16e. The amount of concrete 16e is adjusted so as to increase. As a result, the spar direction dimension of the wall column 15 is made the same as the spar direction dimension of the beam 13 to which the upper end portion of the wall column 15 is coupled so that the wall column 15 does not protrude from the beam 13 in the spar direction. Can do. As a result, the space of the room defined by the wall pillar 15 and the beam 13 can be clearly finished. Preferably, the size in the girder direction of the wall column 15 is the same as that of the beam 13 to which the lower end portion of the wall column 15 is coupled. Note that the configuration of FIG. 5 may be applied to all wall columns 15.

  Further, the center between the columns of the wall column 15 extending in the direction between the beams is preferably located at the center of the interval between the two columns 17 (see FIG. 3A) at the same position in the beam direction as the wall column 15. However, it may be shifted from the center of this interval in the direction between the beams.

  As shown in FIGS. 3 and 4, in each of the lower floor frame 3 and the uppermost floor frame 5, each of the two ramen structures 7 and 9 is provided with a plurality in the vertical direction and spaced apart in the girder direction. Column 17 and a plurality of beams 19 extending in the girder direction at the upper end of the corresponding floor (frame). Further, in each of the lower floor frame 3 and the uppermost frame 5, each of the plurality of beams 19 extends in the spar direction between columns 17 adjacent to each other in the horizontal direction, and both ends are coupled to these columns 17 ( A rigid structure is formed to form a ramen structure. In addition, the pillar 17 may be comprised so that it may extend continuously over several floors. In this case, the pillars 17 whose positions in the horizontal plane are the same among a plurality of floors are shared in these floors.

  3A and 3B, the broken lines indicate the beams 13 and 19 on the floor shown in FIGS. 3A and 3B, which are located in front of the page (corresponding to the upper side in the vertical direction).

  In the lower frame 3 of each floor, each beam-attached structure 11 includes a beam 13 extending in the beam-to-beam direction from one of the two ramen structures 7 and 9 to the other as shown in FIGS. Below the beam 13, there is a seismic wall 21 coupled to the beam 13 and extending in the direction between the beams from one of the two frame structures 7 and 9 to the other. In the lower floor frame 3 of each floor, the beamed structure 11 positioned at one or both ends in the girder direction may have a wall that is not a seismic wall instead of the seismic wall 21. This wall, which is not a seismic wall, may be coupled to the beam 13 below the beam 13 and extend in the inter-beam direction from one of the two frame structures 7 and 9 to the other. Therefore, in the lower floor frame 3 of each floor, among the plurality of beamed structures 11 described above, each beamed structure 11 positioned at least in the middle of the beam direction includes the beam 13 and the earthquake resistant wall 21. In the present embodiment, on the lower floor, the thick plate-like structure 11 with a beam serves as a boundary of the dwelling unit. Therefore, a space sandwiched in the beam direction by two structures 11 with beams adjacent in the beam direction becomes one dwelling unit.

  In the uppermost frame 5, the wall column 15 is separated from the two ramen structures 7 and 9 in the beam-to-beam direction as shown in FIGS. 3B and 4. It is arranged in the middle. As shown in FIG. 4, an opening 23 is formed between the wall column 15 and one of the rigid frame structures 7. The opening 23 has, for example, a height from the floor to the ceiling of the dwelling unit, and has a beam-to-beam dimension from the wall column 15 to one of the ramen structures 7. Similarly, an opening 23 is formed between the wall column 15 and the other rigid frame structure 9. The opening 23 has, for example, a height from the floor to the ceiling of the dwelling unit, and has a beam-to-beam dimension from the wall column 15 to the other rigid frame structure 9.

  In addition, each pillar 17, each beam 13, each beam 19, the wall pillar 15, and each earthquake-resistant wall 21 may be integrated with each other by being formed of reinforced concrete.

  Preferably, as shown in FIG. 3B, in the uppermost frame 5, one of the two beamed structures 11, 14 positioned in the middle of the beam direction and adjacent to each other in the beam-to-beam direction. 14 has a wall column 15, and the other beamed structure 11 is coupled to the beam 13 below the beam 13 of the beamed structure 11, from one of the two ramen structures 7 and 9 to the other. It has the earthquake-resistant wall 21 extended in the direction between beams.

  Preferably, as shown in FIG. 3B, among the plurality of beamed structures 11 and 14 arranged in the beam direction on the top floor, the beamed structures 11 positioned at both ends in the beam direction are It has the above-mentioned seismic wall 21.

  Preferably, the lower end portion of each wall column 15 described above is coupled (joined) to the beam 13 of the beam-attached structure 11 provided on the floor one level lower than the floor of the wall column 15. The dimension of the 15 digit direction is almost the same as the dimension of the beam 13 in the digit direction. In the example of FIG. 3B, the beam 13 and the wall column 15 have the same girder direction dimensions as those of the later-described seismic wall 21.

  Preferably, the lower end portion of each wall column 15 described above is coupled to the beam 13 of the beam-attached structure 11 having the earthquake-resistant wall 21 provided on the floor one level lower than the floor of the wall column 15. .

  In addition, the upper end part of each earthquake-resistant wall 21 of each floor is couple | bonded (joined) to the beam 13 supported by this earthquake-resistant wall 21 from the downward direction. The lower end portion of each seismic wall 21 of each floor above the second floor is joined (joined) to the beam 13 on the floor one level lower than the floor (here, the top floor) of the seismic wall 21.

  According to the present embodiment, in the top floor side frame 5, one or more beams 13 among all the beams 13 are joined (joined) to the wall column 15 instead of the earthquake resistant wall 21, and the wall column 15 lowers the beam. Supported by. On the other hand, in the lower floor frame 3 of each floor, the wall column 15 is not provided, and any of the beams 13 positioned in the middle of the beam direction (that is, not positioned at the end in the beam direction). 13 is connected (joined) to the earthquake-resistant wall 21 instead of the wall column 15 and is supported by the earthquake-resistant wall 21 from below. In this respect, the uppermost floor frame 5 and the lower floor frame 3 are different from each other.

  According to the above-described embodiment of the present invention, the following effects can be obtained in the building 10 in which the lower floor frame and the uppermost floor frame are different from each other.

  According to the above-described embodiment of the present invention, the wall pillar 15 that supports at least a part of the beams 13 from the lower side among the plurality of beams 13 extending in the inter-beam direction is provided on the top floor side frame 5. It arrange | positions in the middle of the two ramen structures 7 and 9 so that it may space apart from the two ramen structures 7 and 9 in the beam-to-beam direction. With this configuration, a space can be secured between the ramen structures 7 and 9 and the wall column 15, and this space can be utilized in the floor plan design. Therefore, the degree of freedom in designing the floor plan can be increased. Further, the use of the wall column 15 instead of the seismic wall 21 on the top floor does not adversely affect the seismic strength of the building 10. Therefore, the design freedom of the floor plan can be increased without adversely affecting the seismic strength of the building 10, and as a result, the added value of the building 10 can be increased.

FIG. 6 is a plan view showing an example of the floor plan in FIG.
In the plan view of FIG. 6, a range A (a range surrounded by a thick broken line) can be one wide dwelling unit. In this range A, the spaces on both sides in the beam direction of the wall column 15 are communicated by the openings 23 on both sides of the wall column 15 in the beam direction. Thereby, the space of the both sides of the column direction of the wall pillar 15 can be made into the space of one dwelling unit. In this regard, in the lower floor, as shown in FIG. 3A, one dwelling unit has an area between the earthquake-resistant walls 21 adjacent to each other in the girder direction (hereinafter referred to as a reference area). A has an area twice as large as the reference area.
Further, in the plan view of FIG. 6, each of the range B (the range surrounded by the thick broken line) and the range C (the range surrounded by the thick broken line) can be made into one wide dwelling unit. The dwelling unit in the range B and the dwelling unit in the range C are separated from each other by the partition wall 25. The partition wall 25 is located in the middle of the columns 17 (or the beams 13 adjacent to each other) adjacent to each other in the girder direction, and extends from the frame structure 7 to the frame structure 9. Each of the range B and the range C includes a region from the partition wall 25 to the wall column 15 adjacent to the partition wall 25 in the digit direction (a half of the reference width) and a reference width adjacent to the wall column 15. Has a region.
Preferably, the partition wall 25 described above is a dry wall (dry sound insulation partition wall).

  When the range A in FIG. 6 does not need to be one dwelling unit, in the range A, each opening 23 can be closed with a dry wall (dry sound insulation partition wall), and the range A can be made into two dwelling units. . The floor plan design on the top floor is not limited to the example of FIG. 6. For example, the floor plan can be freely designed by changing the positions of the wall pillar 15 and the opening 23 from FIG. 6 within the scope of the present invention.

Preferably, each beam 19 on the balcony 27 side is a flat beam on each floor (in the example of FIG. 4, the top floor and each lower floor) of the building 10 (for example, the building 10 having 15 floors or less). In the flat beam 19, as shown in FIG. 4, the dimension (beam width) in the horizontal direction (inter-beam direction) orthogonal to the longitudinal direction is larger from the upper surface to the lower surface (beam reason). Since the flat beam 19 can increase the vertical dimension of the balcony-side window, the openness can be improved. In particular, in the top floor side frame 5, as described above, the degree of freedom in designing the floor plan can be increased, and as a result, the added value of the building 10 can be further increased. In FIG. 4, reference numeral 29 indicates a corridor.
However, each beam 19 on the balcony 27 side may be a normal beam on each floor of the building 10 (in the example of FIG. 4, the uppermost floor and each lower floor). In a normal beam, the horizontal dimension (beam width) perpendicular to the longitudinal direction is smaller than the dimension from the top surface to the bottom surface (beam length).
