Further, a beam between columns 82 on the outer peripheral portion (outer wall) is a wall beam 93, and a duct shaft 80 is provided in the center of the window 85. A duct 87 is housed inside the duct shaft 80, and an air outlet 86 is provided on a wall surface that divides the duct shaft 80 and the classroom 84.
As a result, the ceiling height of the classroom 84 can be increased while keeping the floor height of the building low.

  At this time, if all the equipment piping arranged in the ceiling back space of the corridor can be accommodated in the piping shaft on the outer wall side, it becomes easy to update the equipment and change the layout. However, since the duct shaft 80 is located at the center of the window 85 formed between the pillars 82, when the duct shaft 80 is enlarged, most of the window 85 is blocked, and a necessary lighting area cannot be secured in the room.

As shown in FIG. 1, the building 10 according to the first embodiment has wall pillars 12 that are continuously arranged at predetermined intervals at opposite positions of the side surfaces 29 on both sides.

  The wall column 12 is formed of reinforced concrete, and the column formation dimension b in the direction orthogonal to the side surface 29 is longer than the column width dimension a in the direction parallel to the side surface 29. The wall column 12 is disposed at a position protruding outward from the side surface 29 and does not enter the interior space 36 side of the building 10.

  The space outside the side surface 29 and sandwiched between the adjacent wall pillars 12 is the equipment shaft 24, and the wall pillar 12 also serves as side walls on both sides of the equipment shaft 24.

  The equipment shaft 24 is a space in which the equipment piping 25 distributed to the internal space 36 of the building 10 is accommodated, and is partitioned from the internal space 36 by the partition wall 22 at the position of the side surface 29. A gallery 28 is provided outside the equipment shaft 24.

2, the partition wall 22 is formed of reinforced concrete and partitions the internal space 36 and the equipment shaft 24 of each floor. At this time, the partition wall 22 is provided in a direction parallel to the partition wall 22, and no beam is provided between the wall pillars 12.
Thereby, the process of the partition wall 22 becomes easy and the through-hole for taking in the equipment piping 25 in the ceiling back space 37 and the underfloor space 73 can be opened easily.

  Further, a gallery 38 for connecting to an exhaust duct 74 disposed in the ceiling space 37 is provided on the upper portion of the partition wall 22 of each floor. If this louver 38 is used, the equipment piping 25 can be taken in without the need for processing the through hole.

  On the upper part of the louver 38, a flange portion 26 is formed integrally with the partition wall 22 and made of reinforced concrete and protrudes to the outside. Thus, the louver 38 is protected from wind and rain and direct sunlight. Further, both end surfaces of the flange portion 26 are joined to the side surfaces of the wall column 12. Thereby, the strength of the partition wall 22 is ensured.

  Further, as shown in the external view of FIG. 3, a louver 28 is provided outside the equipment shaft 24 to block the field of view.

Recycled wood is used for the louver, and it is provided in the range from the first floor to the top floor across the entire width between the wall pillars 12. As a result, the equipment shaft 24 is protected from wind and rain and direct sunlight, and the view from the outside is blocked to improve the appearance of the building 10.

  Thus, the equipment shaft 24 can be eliminated from the internal space 36 of the building 10 by providing the equipment shaft 24 outside the side surface 29 of the building 10 and configuring the side wall of the equipment shaft 24 with the wall pillar 12. In addition, by making the partition wall 22 a non-beam structure, it is possible to easily take in the equipment piping 25 from the equipment shaft 24 to the internal space 36 of the building 10.

  Further, as shown in FIG. 1, an installation shaft 24 is provided every other wall pillar 12. Thereby, the freedom degree of the taking-out position of the equipment piping 25 increases, and it becomes easy to route the equipment piping 25 in the internal space 36 of the building 10. As a result, the facility piping 25 can be easily routed by using the facility shaft 24 not only at the time of construction but also at the time of changing the equipment or layout.

As a result, for example, even if a resident is in the internal space 36 of the building 10, the work can be performed, and it is possible to flexibly cope with a change in equipment or layout.
Further, a wall beam 30 is provided between the wall columns 12 where the equipment shaft 24 is not provided. That is, the equipment shafts 24 and the wall beams 30 are alternately provided between the wall pillars 12.

  As shown in the QQ line cross section of FIG. 4, the wall beam 30 is formed of reinforced concrete in a U-shaped vertical section, and the vertical portion 30 </ b> C at the center of the wall beam 30 is an outer wall. The vertical portion 30C as an outer wall is joined to the floor slab 70, the upper side of the floor slab 70 is a waist wall 30C1, and the lower side of the floor slab 70 is a hanging wall 30C2. Moreover, the upper and lower end portions of the wall beam 30 are projected outward to form an upper-level window base 30U and a lower-level ridge 30D.

A plurality of wall beams 30 are arranged with a predetermined space in the vertical direction, and a window 40 is formed between the lower end 30D of the upper wall beam 30 and the upper end 30U of the lower wall beam 30.
Thus, the lighting area is ensured by the installation shaft 24 and the window 40 provided for every other.

  As shown in FIG. 5, both end surfaces of the wall beam 30 are joined to the side surface of the wall column 12, and the joint portion is reinforced by a joint 15. Thereby, the twist of the wall column 12 is suppressed.

  In addition, H-shaped steel 14 is provided inside the wall column 12 so as to be biased toward the internal space 36 side of the building 10. Thereby, the outer side of the building 10 becomes a concrete finished surface, and the aesthetic appearance is maintained. The flange 14F of the H-shaped steel 14 can be exposed at the end surface of the wall column 12 on the inner space 36 side.

  As shown in FIG. 1, a large beam 20 is bridged between the wall pillars 12 facing each other with the internal space 36 of the building 10 interposed therebetween.

  Here, the large beam 20 is a concrete-filled beam in which the concrete 34 is filled on both sides of the web of the H-shaped steel 30. Thereby, the rigidity of the large beam 20 can be increased, and the fine vibration transmitted to the large beam 20 is suppressed.

  Further, the girder 20 is not supported by a pillar in the internal space 36 of the building 10. In this way, by making the internal space 36 a column-free space, the degree of freedom in the plan of the internal space 36 is increased, and the internal space 36 can be used effectively.

  The large beam 20 is not provided with a small beam. In this way, by planning the large beam 20 as a non-small beam, it is possible to freely route the equipment piping at the upper part of the slab 70 supported by the large beam 20 and the lower part of the slab 70. As a result, it is possible to easily cope with the update of the equipment and the layout change.

Next, the earthquake resistant structure of the building 10 will be described.
As shown in the overall structural diagram of the building 10 in FIG. 7, a core A portion 46 and a core B portion 48 that aggregate shared functions are formed as column-free spaces in the wife portion of the building 10 in a direction orthogonal to the girder 20. The internal space 36 is provided therebetween.

  The wall 42 in the direction parallel to the beam 20 of the core A portion 46 is a first earthquake-resistant wall having earthquake-resistant performance. Further, the wall 44 of the core B portion 48 in the direction parallel to the beam 20 is also a first earthquake-resistant wall having earthquake-resistant performance. And the 1st seismic walls 42 and 44 and the floor slab 70 of each floor are joined.

  In this manner, the building 10 is sandwiched between the first seismic walls 42 and 44 from the wife side, so that the seismic force in a direction parallel to the beam 20 can be obtained even though the internal space 36 is a column-free space. Can withstand.

  On the other hand, the wall 50 of the core A portion 46 in the direction perpendicular to the large beam 20 is a second earthquake resistant wall having earthquake resistance. Moreover, the wall 52 of the core B part 48 in the direction orthogonal to the beam 20 is also a second earthquake-resistant wall 52 having earthquake-resistant performance. And the 2nd earthquake resistant walls 50 and 52 and the floor slab 70 of each floor are joined.

  Accordingly, the second seismic walls 50 and 52 and the outer wall 30 can withstand the seismic force in the direction orthogonal to the beam 20 even though the inner space 36 is a column-free space.

Next, an example of the layout of the internal space 36 of the building 10 will be described.
As shown in FIG. 8, a corridor 55 is provided in the center of the internal space 36, and connects the core A part 46 and the core B part 48. Living rooms are arranged on both sides of the corridor 55, and a large room 56 to a small room 58 are arranged according to the purpose.

  At this time, if each room is arranged corresponding to the interval between the wall pillars 12, all the rooms and the equipment shaft 24 can be made to correspond. As a result, regardless of the large room 56 and the small room 58, it is possible to flexibly cope with the update of the equipment and the layout change. Here, an inspection door 62 is provided on the inner space 36 side of the piping shaft 24. As a result, daily maintenance and service can be easily performed.

In addition, although the example which has arrange | positioned the corridor 55 in the center of the internal space 36 was demonstrated, you may provide the corridor 55 in the window side. Further, it is possible to make one large room without dividing the internal space 36.
As described above, according to the present embodiment, it is possible to provide the building 10 that can flexibly cope with the renewal of the equipment and the layout change while securing the daylighting area.

(Second Embodiment)
As shown in FIG. 9, a building 60 according to the second embodiment has two gate-type seismic walls 54 provided in a direction orthogonal to the girder 20.

The portal seismic wall 54 is made of reinforced concrete and surrounds the opposing side surfaces 29 of the building 60. The beam portion 54 </ b> H is bridged on the top of the side surface 29 in a direction orthogonal to the large beam 20. Further, the column portion 54V is provided outside the wall column 12 continuously arranged at a predetermined interval with the wall column 12 interposed therebetween, and is joined to both end portions of the beam portion 54H at the upper portion.
As a result, the column portion 54V has a gate shape that supports the beam portion 54H.
Others are the same as those in the first embodiment, and a description thereof will be omitted.

  The gate-shaped seismic wall 54 having a gate shape has an improved seismic strength in a direction perpendicular to the large beam 20 because the upper portion of the column portion 54V and the beam portion 54H are joined. Thereby, for example, even if the column part 54V cannot secure a sufficient width dimension W in the direction orthogonal to the girder 20 of the building 60 due to site restrictions, etc. Seismic strength can be secured.
