[0006]

1 to 4 show an embodiment of the present invention. The building of this embodiment is shown in FIGS.
Is a tower-like (30 stories or more, 100 m or more) high-rise apartment building having a substantially square planar shape, as shown in FIG. 3 and FIG. Main frame 2, a core wall 2 provided so as to surround the central portion, a projecting slab 3 provided outside the core wall 2, and a beamless slab 4 provided outside the main body. And

According to the plan of this building, the inside of the core wall 2 is a common zone 5 in which elevators and staircases are arranged as shown in FIG. A common corridor 6 is provided in the area of the slab 3, and the area of the beamless slab 4 outside the common corridor 6 is a dwelling unit zone 7. Further, an equipment shaft 8 provided facing the common corridor 6 and also serving as a meter box of each dwelling unit is provided at a position in contact with the core wall 2.

[0008] Outer peripheral frame 1 provided on the outer periphery
Is a high-rigidity reinforced concrete structure composed of an outer peripheral column 9 and an outer peripheral beam 10, and constitutes a tubular frame that forms an outer shell of the entire building. Reference numeral 11 denotes a spring slab for a balcony.

The core wall 2 is of high rigidity consisting of a series of cast-in-place reinforced concrete multi-story shear walls connected from the bottom to the top of the building. In the present embodiment, the core wall 2 is divided into four parts in a plane, and a boundary beam 1 is provided on each floor between the divided core walls 2.
2 are installed. As the boundary beam 12, a steel beam such as an H-beam is used, and when the entire core wall 2 is deformed by an earthquake, the boundary beam 12 yields early (when bending yield precedes and when shear yielding precedes). Plastic deformation, thereby absorbing seismic energy and damping vibration. That is, the boundary beam 12 functions as a vibration damper.

The projecting slab 3 is made of cast-in-place reinforced concrete provided integrally with the core wall 2, and is provided on both left and right sides of the core wall 2 as shown in FIG. Is provided with a small beam 13. The small beam 13 is the only beam provided in the dwelling unit zone 7, and it is preferable to adopt a low-cast precast concrete beam (PCa beam) as the small beam 13, and to introduce prestress as necessary. Is preferred.

The beamless slab 4 is made of a unidirectional precast concrete slab (PCa version) laid between the outer peripheral frame frame 1, the spring slab 3, and the small beam 13. The slab 4 makes the entire dwelling unit zone 7 a pillar-free and beamless space except for the small beams 13, and the whole dwelling unit zone 7 can be freely partitioned to set a dwelling unit of a desired plan at a desired position. It has become something. In addition, a void slab may be adopted as the PCa plate as the beamless slab 4 or a prestress may be introduced. Further, as the beamless slab 4, a half PCa plate also serving as a floor formwork and a cast-in-place concrete poured over the half PCa plate can be adopted. In any case, the thickness of the beamless slab 4 is 300 m in order to secure normal floor rigidity.
m is sufficient.

In this embodiment, as shown in FIG. 4, the upper surface levels of the projecting slab 3 and the beamless slab 4 are lowered by about 300 mm from the floor level, and a finishing floor 14 is provided on the upper part of the slab 3 and the beamless slab 4. A double floor space is secured throughout the corridor 6 and the dwelling unit zone 7. Thereby, a water place can be freely set at a desired position in a dwelling unit, and it is advantageous in securing sound insulation between the upper and lower floors. By making the lower surface of the beamless slab 4 a straight ceiling finish, even if the floor height is about 3,300 mm,
An effective ceiling height of about 00 mm can be secured.

In the building according to the present embodiment having the above structure, the vertical force and the horizontal force of the entire building are mainly applied to the outer peripheral frame 1 and the core wall 2 to achieve excellent structural stability and seismic performance. Therefore, columns and beams are unnecessary at all except for the small beam 13 except for the outer peripheral frame structure 1 and the core wall 2, which is extremely reasonable in structure.

In particular, since the core wall 2 is divided into a plurality of parts and the boundary beam 12 as a vibration damper is erected between them, an excellent vibration damping effect by the boundary beam 12 can be obtained. Since the deformation is concentrated on 12, the occurrence of cracks in the entire core wall 2 can be prevented.

Further, since the projecting slab 3 is provided integrally with the core wall 2 and the projecting slab 3 and the small beam 13 support and support the beamless slab 4 of the dwelling unit zone 7, the whole dwelling unit zone 7 is substantially formed. It is possible to secure a large effective ceiling height even if the floor height is relatively low, and it is possible to realize the separation of the so-called skeleton and infill, and it is possible to fully support the free plan . Then, the beamless slab 4 is converted to a PCa version or a half PCa.
By using a plate and cast-in-place concrete, it is possible to secure excellent floor rigidity while being lightweight, and it is also advantageous in terms of workability and cost. Also, as shown in FIG. 3, the span of the PCa plate and the half-PCa plate constituting the beamless slab 4 is unified by aligning the position of the side surface of the small beam 13 with the position of the tip of the projecting slab 3. Good workability.

A structure in which the beamless slab 4 of the dwelling unit zone 7 is directly extended to the area of the common corridor 6 and directly supported by the core wall 2 without providing the projecting slab 3 may be considered. In that case, the span of the beamless slab 4 becomes too large, and
Is too large, which is not preferable.

Furthermore, in this embodiment, the equipment shaft 8 provided facing the common corridor 6 is provided not on the dwelling unit zone 2 side but on the core wall 2 side. With the provision, a high-level free plan can be realized in this respect as well.

That is, in an apartment house, it is usual to provide an equipment shaft which also functions as a meter box in the vicinity of the entrance of each dwelling unit, facing the common corridor. Conventionally, the entrance of each dwelling unit is set at a position avoiding the equipment shaft. In the case where the layout of the dwelling units is prioritized, the position and size of the equipment shaft may be restricted. However, in this embodiment, if the equipment shaft 8 faces the common corridor 6 as well. However, by arranging it on the core wall 2 side instead of the dwelling unit zone 7 side, it is possible to freely and optimally set the dwelling unit layout including the position of the entrance irrespective of the equipment shaft 8. Also, since the equipment shaft 8 can be optimally arranged regardless of the layout of the dwelling units, it is possible to design the piping and wiring provided inside thereof with the highest priority on workability and maintainability, and to sufficiently standardize the facility. It becomes possible.

The provision of the equipment shaft 8 on the core wall 2 side as described above means that the equipment shaft 8 is slightly separated from each dwelling unit. The original function of the box is not impaired at all. Of course, it is necessary to secure a piping wiring space for connecting the equipment shaft 8 and each dwelling unit so as to cross the common corridor 6, but as described above, the projecting slab 3 and the beamless slab 4
And the double floor space is secured in the common corridor 6 and the dwelling unit zone 7, such a piping and wiring space can be secured without any trouble. Further, since the equipment shaft 8 is provided in the range of the cast-in-place concrete pop-out slab 3, the floor opening in the equipment shaft 8 can be easily and easily provided at the time of the construction of the pop-out slab 3. Accordingly, the opening reinforcement can be easily and reliably performed. At this point, if the equipment shaft 8 is provided in the range of the beamless slab 4, processing on a PCa plate or a half PCa plate for forming the beamless slab 4 becomes necessary, In this case, the span length changes, and thus the workability deteriorates, which is not preferable.

An embodiment of the present invention has been described above.
The present invention is of course not limited to the above embodiment,
The scale and form of the whole building, the plane plan, the form of division of the core wall 2, and the plane plan of the common zone 5 therein can be appropriately changed, for example, as shown in FIG.

[0021]

According to the first aspect of the present invention, there is provided an apartment building mainly including an outer frame and a core wall, and a protruding slab constituting a floor of a common corridor is provided around the core wall. The structure supports the flat non-beam slab in the dwelling unit zone with the ramen frame, so the vertical and horizontal forces of the entire building are mainly borne by the outer frame and the core wall, resulting in excellent structural stability and seismic performance. Therefore, since it is possible to have substantially no pillars and no beams other than the outer frame and the core wall, the structure is extremely reasonable, and it is possible to respond to a high-level free plan. Can achieve a high ceiling height. In addition, since the core wall is divided into a plurality of parts and a boundary beam as a vibration damper is erected there, an excellent vibration control effect by the boundary beam can be obtained. In addition, since the equipment shaft facing the common corridor was provided at a position in contact with the core wall,
It is possible to freely and optimally set the layout of the dwelling units and the position of the entrance in the dwelling unit zone regardless of the equipment shaft.

According to a second aspect of the present invention, as the beamless slab constituting the floor of the dwelling unit zone, a precast concrete slab,
Alternatively, since a half precast concrete slab and a cast-in-place concrete cast thereon are employed, excellent floor rigidity can be ensured while being lightweight, and it is advantageous in terms of workability and cost.
