DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In a conventional building structure, columns and beams are provided not only in the outer frame of the building and the core but also in the living room in order to obtain strength. This is not desirable in terms of architectural planning such as construction and construction, and also impairs livability and aesthetics. In order to solve the above-mentioned problems, the applicant of the present invention has previously proposed and obtained a patent for a structure of a building having no pillars or beams in a living room, and the content is disclosed in Japanese Patent Publication No. 4-28064. Is disclosed. (Hereinafter referred to as a patented building)

[0003] In this patented building, the inside of the building is constituted by a three-dimensional ramen structure A, as schematically shown in FIG.
This is used as a core part for common facilities such as corridors and for water around toilets and bathrooms where there are few restrictions on beams and columns even in dwelling units, and a three-dimensional ramen structure part A and a short span frame surrounding the outside A column-free space surrounded by equal-thickness slabs C, which are connected to the tube structure portion B formed by the ramen structure structure surface, with equal-thickness slabs C, which have no beams and whose middle portion does not receive support from columns, are surrounded by equal-thickness slabs on the upper and lower floors Can be used as a living room or dining kitchen with a free layout.

[0004]

However, recently, there has been a tendency to increase the number of dwelling units by increasing the reference floor area, and in that case, the depth dimension of the equal thickness slab region in the above-mentioned patented structure is unnecessarily increased. When it is increased, the transmission of the horizontal force between the outer tube structure portion B and the inner three-dimensional frame structure A becomes poor, and the strength of the whole building may be reduced. In addition, when the reference floor area increases, the number of pillars of the outer frame increases when a short-span frame is used to form a ramen structure, so that there is a possibility that construction costs will rise and the feeling of openness when living will be impaired. Further, even if the reference floor area increases, the central side of the building is difficult to obtain lighting and ventilation and the layout of the dwelling units becomes complicated, so that the dwelling units may not be suitable for dwelling units and may be spaces that cannot be effectively used. In view of the above, the present invention provides a structure of a building that can effectively cope with a building having an increased reference floor area while keeping the basic idea of the above-described building having a patent structure as it is.

[0005]

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 of a reference floor showing an outline of the entire structure of a building, and FIG. 2 is an enlarged partial cross-sectional view taken along line XX of FIG. An outer peripheral frame 1 of a rectangular building is composed of a frame structure with columns 2 and beams 3, and a void 4 is provided at the center of the outer peripheral frame 1. A core 8 having a three-dimensional rigid frame structure in which a pillar 5 and a beam 6 are rigidly connected in an intersecting manner and a floor slab 7 is stretched between the beams 6 and 6 is provided around the outer periphery of the void 4. The frame 1 is connected to the frame 1 by an equal thickness slab 9.

[0007] periphery Frame 1, without using a tube structure according to short-span frames as in the case of building patent structure in this embodiment, the spacing of the pillars 2,2 (span) 6 meters S ₁ example standard or It is set to about 8 meters more than that. The equal thickness slab 9 may be reinforced by burying steel bars or steel frames inside as necessary in order to have the function of a beam. The thickness of the slab is different from that of the flat slab, and the intermediate portion has a structure not supported by the pillar. The core 8 is set apart pillars 5,5 (span) S ₂ For example, a standard order of 6 meters.

The present invention is applied to a building having a longer outer diameter and a larger reference floor area than the building having the patent structure shown in FIG. 4, and in this case, a void provided at the center of the building is used. By setting 4 to a desired size, the outer diameter of the core 8 is increased in accordance with the increase in the outer diameter of the outer peripheral frame 1, and the depth dimension W of the region of the equal thickness slab 9 is appropriately adjusted. In this embodiment, the size of the void 4 is set and the outer diameter of the core 8 is enlarged so that the area of the slab 9 has the same depth dimension W as that of a building having a 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, the depth B ₁ of equal thickness slabs B and 6 m, 3
(A) the outer diameter L ₁ of the building outer periphery Frame 1 in 40m of the building shown in FIG. 3 (b) when the outer diameter L ₁ of the outer peripheral Frame 1 was 45m is set as shown in FIG. 3 . That is, in the building of FIG. 3A with respect to the building of FIG. 4 having no void, the outer diameter L1 of the outer frame ₁ is increased by 5 m and the void 4 is increased by 5 m.
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)
A larger void 4 is provided by the amount of
To expand the outer diameter L _2.

In this way, the three-dimensional frame structure portion with respect to the whole building is increased by the extent that the outer diameter L ₂ of the core 8 is enlarged, and the strength of the whole building is reinforced. Therefore, the outer frame 1 is formed by the short span frame. Instead of a tube structure, a normal frame structure can be used, and the number of columns 2 constituting the outer frame 1 can be greatly reduced. In addition,
In the embodiment of FIG. 3, the distance between the columns 2 and 2 of the outer frame 1 and the core 8
In this embodiment, the distance between the pillars 5 and 5 is set to be equal, for example, about 6 m, and the pillars 2 and 5 are arranged at positions where they are aligned in a straight line. In the embodiment of FIG. 2,2
In this embodiment, the distance between the columns 2 and 5 is wider than the distance between the columns 5 and 5 of the core 8 and is, for example, about 8 m. In addition, in the embodiment of FIG. 3, illustration of the wall dividing the dwelling unit is omitted.

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

The present invention is not limited to the above embodiment, but can take various modifications. For example, in the embodiment, the depth dimension of the equal-thickness slab area is made substantially equal to that of the patent-structured building, and the number of pillars of the ramen structure constituting the outer frame is reduced by the amount of the building expected due to the expansion of the core by the three-dimensional frame structure. In addition, the column interval is set to be substantially equal to or larger than the column interval of the three-dimensional frame structure forming the core. In this regard, the frame structure of the outer frame is the same as that of the patented structure, with the frame structure of the short-span frame tube structure. There is also a mode that only enhances the seismic resistance of the building.

[0012]

As is clear from the above embodiments, the following effects can be expected from the structure of the building according to the present invention. For a building with a large number of dwelling units by increasing the reference floor area, a void is provided at the desired size in the center and the core is expanded, and the area of equal thickness slab connecting the outer frame and the core with the appropriate depth dimension Since it can be ensured, it is possible to create a dwelling unit with high livability and aesthetics based on a free dwelling unit plan by using the column-less living room space formed by the equal thickness slab. In addition, if the core with the three-dimensional ramen structure is expanded, the ratio of the core to the area of the equal thickness slab increases, and the strength of the entire building increases. If it is wide, the number of pillars can be reduced, the open-ended outer frame can be constructed at low cost, and the position of the pillars can be set arbitrarily as long as the strength allows, so the above-mentioned In cooperation with the living room space, the degree of freedom of the floor plan can be increased. In addition, when the column spacing of the outer peripheral frame is maintained in the tube structure using the short span frame, the strength of the entire building is further increased, so that a reliable living environment with high earthquake resistance is obtained. further,
The voids that enlarge the core provide lighting and ventilation to each dwelling unit from the center side of the building, and also make it possible to use the inside of the wide void for a play space or the like, thereby providing a comfortable and spacious living environment.
