[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a building such as a condominium.

[0002]

2. Description of the Related Art In a conventional building structure, columns and beams are provided not only on the outer perimeter frame and core of the building but also on the living room in order to obtain strength. It is not preferable in construction planning such as construction and construction, and it also impairs habitability and aesthetics. Therefore, as a solution to the above problems, the applicant of the present invention first proposed a patent for a structure of a building in which no columns or beams are provided in the living room, and acquired the right, the contents of which are Japanese Patent Publication No. 4-28064. Is disclosed in. (Hereafter referred to as a patented building)

In the building of this patent structure, as shown in the outline of FIG.
This is used as a core part for shared facilities such as corridors, and in bathrooms such as bathrooms where there are few restrictions on beams and columns in dwelling units, bathrooms, etc., and by the short span frame surrounding the three-dimensional rigid frame structure part A and its outside. A column-free space surrounded by the equal-thickness slabs on the upper and lower floors by connecting the tube structure portion B formed by the frame structure structure with a uniform-thickness slab C without beams to support the pillar in the middle. Can be used as a living room or a dining kitchen with free layout.

[0004]

However, recently, there is a tendency for the number of buildings having a larger number of dwelling units to be increased by increasing the standard floor area, and in that case, the depth dimension of the equal thickness slab region in the building of the above patent structure is undesired. If it is increased to 1, the transmission of horizontal force between the outer tube structure portion B and the inner three-dimensional rigid frame structure A may be deteriorated, and the strength of the entire building may be reduced. Further, when the standard floor area increases, the number of columns of the outer frame increases when the frame structure of the short span frame is constructed, which may increase construction costs and impair the feeling of openness during living. Further, even if the standard floor area increases, it is difficult to obtain lighting and ventilation on the center side of the building and the division of living units becomes complicated. In view of this, the present invention provides a structure of a building, which is capable of effectively utilizing the basic idea of the building with the above-mentioned patent structure and effectively dealing with a building having an increased standard floor area.

[0005]

In the structure of a building according to the present invention, a core having a three-dimensional rigid frame structure is provided in the center of a building having an outer peripheral frame formed of a rigid frame structure, and a beam is provided between the core and the outer peripheral frame. It is connected to the mold with a uniform thickness slab without pillars to form a pillarless living space between the uniform thickness slabs on the upper and lower floors, a common corridor is provided on the inner circumference side of the core, and the outer circumference side of the core and the above Each living unit is provided by dividing the living space of the uniform thickness slab area into living units, and a void set to a desired size for expanding the outer diameter of the core according to the outer diameter of the outer perimeter frame is provided in the center of the shared corridor, and The depth dimension of the uniform slab area was adjusted appropriately. In addition, in the structure of the building according to the present invention, the column spacing of the frame structure constituting the outer peripheral frame is set to be equal to or longer than the column spacing of the three-dimensional frame structure constituting the core.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a building according to the present invention will be described below in detail with reference to the embodiments shown in FIGS. FIG. 1 is a plan view showing a general structure of a building on a standard floor, and FIG. 2 is an enlarged partial sectional view taken along line XX of FIG. An outer frame 1 of a rectangular building is formed by a frame structure frame composed of columns 2 and beams 3, and a void 4 is provided at the center of the outer frame 1. On the outer periphery of the void 4, a core 8 having a three-dimensional rigid frame structure in which a pillar 5 and a beam 6 are rigidly joined in a cross shape and a floor slab 7 is stretched between the beams 6 and 6 is provided. The frame 1 and the frame 1 are connected by a uniform slab 9.

In this embodiment, the outer frame 1 does not use a tube structure with a short span frame as in the case of a building with a patent structure, but the interval (span) S ₁ between the columns 2 and 2 is, for example, a standard 6 meters or It is set to about 8 meters above that. The uniform thickness slab 9 may be reinforced by embedding reinforcing bars or steel frames inside if necessary to have the function of a beam. However, as in the case of a patent structure building, there is no beam type outside. The thickness of the slab is different from that of the flat slab. In the core 8, the interval (span) S ₂ between the pillars 5 and 5 is set to, for example, the standard 6 meters.

The building to which the present invention is applied is applied to a building having a longer outer diameter and a larger standard floor area than the case of the building of the patented structure shown in FIG. 4, in which case a void provided in the center of the building. By setting No. 4 to a desired size, the outer diameter of the core 8 is increased according to the increase of the outer diameter of the outer peripheral frame 1, and the depth dimension W of the uniform thickness slab 9 region is appropriately adjusted. In this embodiment, the outer diameter of the core 8 is enlarged by setting the size of the void 4 so that the area of the uniform thickness slab 9 has the depth dimension W substantially equal to that in the case of the patent structure without voids. For example, in the building shown in FIG. 4, the outer diameter C ₁ of the outer frame C is 35 m, and the outer diameter A _{1 of the} core A is 23 m.
m, the depth dimension B ₁ of the uniform thickness slab B is 6 m, and FIG.
When the outer diameter L ₁ of the outer frame 1 is 40 m in the building shown in (a) and the outer diameter L ₁ of the outer frame ₁ is 45 m in the building shown in FIG. 3 (b), it is set as shown in FIG. . That is, in the building of FIG. 3A, the outer diameter L ₁ of the outer frame ₁ is expanded by 5 m in the building of FIG.
Was larger outer diameter L ₂ of the core 8 is provided, 5 from the building of the outer diameter L ₁ a diagram of the outer circumferential Frame 1 in the building of FIG. 3 (b) 3 (a)
Core 8 with a larger void 4 provided by the amount of m
Increase the outer diameter L ₂ of.

By doing so, the three-dimensional rigid frame structure portion for the entire building is increased by the amount of the expanded outer diameter L ₂ of the core 8 and the strength of the entire building is reinforced, so that the outer frame 1 is formed by the short span frame. Instead of the tube structure, a normal rigid frame structure can be used, and the number of columns 2 forming the outer peripheral frame 1 can be significantly reduced. In addition,
In the embodiment of FIG. 3, the space between the columns 2 and 2 of the outer frame 1 and the core 8
2 shows an embodiment in which the pillars 5 and 5 are arranged at equal intervals of, for example, about 6 m, and the pillars 2 and 5 are aligned in a straight line. In the embodiment of FIG. 2, 2
In this embodiment, the distance between the pillars 2 and 5 is wider than the distance between the pillars 5 and 5 of the core 8 and is about 8 m, for example, and the pillars 2 and 5 are not aligned on a straight line except for a part. In addition, in the embodiment of FIG. 3, illustration of a wall for dividing a housing unit is omitted.

The above-mentioned building has an outer frame 1 as shown in FIG.
The housing is divided by a wall 10 extending from the pillar 2 in the depth direction (from the outside of the building to the center). In this example,
Facing the east, west and south sides of the building, each dwelling unit 1
1 is provided, and as shown in FIG. 2, a living room portion 12 using a pillarless space formed between each of the equal-thickness slabs 9, 9 on the upper and lower floors.
A single dwelling unit is constituted by the water supply portion 13 formed between the floor slabs 7, 7 on the upper and lower floors on the outer peripheral side of the core 8. In addition, the inner side of the core 8 facing the void 4 side is mainly used for the common corridor 14 among the common facilities, and a part of the core 8 facing the north side of the building is centrally arranged such as an elevator hall and power distribution equipment. Necessary shared facilities 15 are provided. Further, the void 4 portion uses the ground as a flower bed or a playground for children, and the upper layer side thereof is used as a stairwell for daylighting and ventilation.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be adopted. For example, in the embodiment, the depth dimension of the equal-thickness slab area is made almost equal to that of the patent structure building, and the number of columns of the frame structure constituting the outer frame is reduced by the amount of the strengthening of the building expected by the expansion of the core by the three-dimensional frame structure. However, the column spacing is set to be substantially equal to or more than the column spacing of the three-dimensional rigid frame structure that constitutes the core. In this regard, the frame structure of the outer frame is the frame structure of the tube structure of the short span frame as in the case of the patented structure, and the expansion of the building expected by the expansion of the core by the three-dimensional frame structure is expected. However, there is also a mode in which the earthquake resistance of the building is enhanced.

[0012]

As is apparent from the above embodiments, the following effects can be expected in the structure of the building according to the present invention. For buildings with a larger number of units by increasing the standard floor area, expand the core by providing a void in the center with the desired size, and adjust the depth of the area of equal thickness slab that connects the outer frame and the core. Since it is possible to secure the space, it is possible to create a dwelling unit with high livability and aesthetics under a free dwelling unit plan by using the pillarless living space formed by the uniform slab. If the core with a three-dimensional rigid frame structure is expanded, the ratio of the core to the area of the uniform thickness slab will increase and the strength of the entire building will increase. If it is wide, the number of pillars can be reduced, the outer frame with a feeling of openness can be constructed at low cost, and the position of the pillar can be set arbitrarily as long as the strength allows, so the above-mentioned pillar-free slabs with uniform thickness can be used. It is possible to increase the flexibility of floor plan in cooperation with the living space. Further, when the column spacing of the outer frame is left as the tube structure of the short span frame, the strength of the entire building is further enhanced, so that a reliable living environment with high earthquake resistance can be obtained. further,
Due to the voids that expand the core, lighting and ventilation can be obtained from the center of the building for each dwelling unit, and the wide voids can be used as a play space or the like, so that a comfortable and spacious living environment can be obtained.
