Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of a void-type high-rise building.
[0002]
[Prior art]
In recent years, multi-family dwellings have become increasingly high-rise due to the flow of urban regeneration. In a high-rise building, the aspect ratio (height / width) of the building increases, and the deformation property with respect to horizontal force deteriorates.
Therefore, in conventional high-rise apartment buildings, in order to reduce the aspect ratio of the building while maintaining the standard single-unit area, and to ensure a planar rigidity balance of the building, a void space (open-air space) ), A so-called void-type flat surface is often used. In addition, the structure was often constructed with a pure ramen structure.
FIG. 3 (a) shows such a conventional void-type high-rise building 30, and FIG. 3 (b) is an explanatory plan view in a CC section.
The void space 31 is penetrated in the height direction of the building at the center of the void type high-rise building 30 in the plane direction, and a corridor space 33 is provided around each floor on each floor. A dwelling unit 36 is provided between the void space 31 and the side wall 32. Reference numeral 35 denotes a pillar that forms a part of the pure ramen structure.
In addition, Patent Document 1 discloses that a lower structure that constitutes a lower floor and an upper structure that constitutes an upper story are provided, and a step is provided therebetween to communicate with a lighting space arranged in the center of the building. It describes a multi-story building with a lighting space.

[Problems to be solved by the invention]
However, such a conventional void-type high-rise building has the following problems.
In the void-type high-rise building 30 shown in FIG. 3, there is a problem that the inflow of outside air is insufficient at the bottom of the void space 31 and that sunlight does not easily reach. In other words, it was a space like the bottom of a well, an unattractive space where trees did not grow and the outside air did not enter. The trend became more pronounced as the buildings became taller.
Furthermore, since the void plane as shown in FIG. 3B is applied to the upper floor, the horizontal stiffness of the upper floor is excessively large as compared with the lower floor. Therefore, there is a problem that the vertical rigidity balance with respect to the horizontal external force is not rational.
In addition, in the multi-story building of Patent Document 1, since the second lighting space is added between the lower floor and the upper floor, the whole building is higher than the void type high-rise building of FIG. If the lower floor becomes higher due to the formation, the lighting and ventilation at the bottom of the lower floor will still be deteriorated. Therefore, there is a problem that a sufficient effect cannot be obtained depending on the height of the building.
[0005]
The present invention has been made in view of such a problem, and a void-type high-rise building capable of obtaining a sufficient lighting property and a ventilation property and capable of rationally designing the horizontal rigidity of the building in a well-balanced manner in the vertical direction. The purpose of the present invention is to provide a structure.
[0006]

Meanwhile, the rigidity of the building can be increased.
[0009]
According to a third aspect of the present invention, in the structure of the void-type high-rise building according to the first or second aspect, the wall in the building forming the side-open space has a multi-story earthquake-resistant wall.
According to the present invention, since the walls in the building forming the side vent space are multi-story earthquake-resistant walls, it is possible to provide a building having high rigidity without providing a structural member in the side vent space. As a result, lighting and ventilation are improved as a result. In particular, even in a lower floor where high rigidity is required, a side-vent space can be provided, and the lighting and ventilation of the lower floor can be significantly improved.
[0010]
According to a fourth aspect of the present invention, in the structure of the void-type high-rise building according to any one of the first to third aspects, the horizontal rigidity of the building in the level where the side-open space is provided is lower than the lower level. Less than the horizontal rigidity of the building.
ADVANTAGE OF THE INVENTION According to this invention, it can be set as the building which the horizontal rigidity of the building was rationally comprised with good balance.
[0011]
According to a fifth aspect of the present invention, in the structure of the void-type high-rise building according to any one of the first to fourth aspects, a plurality of the side blow-through spaces are provided in a height direction of the building, and at least the lowermost side The wall inside the building that forms the side space is made up of multi-story shear walls.
According to the present invention, even when a plurality of side stairwells are provided, at least the lowermost side stairwells are formed using the multi-story shear walls, so that the rigidity in the vertical direction is improved with improved building rigidity. It can be a void-type high-rise building. In particular, it is possible to provide a void-type high-rise building having excellent lighting and ventilation at the bottom.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In all the drawings, the same or corresponding members have the same reference characters allotted, and description thereof will not be repeated. Also, in the drawing, in order to clearly show that the predetermined surface is not covered by the floor member, diagonal lines in the surface are indicated by broken lines.
[0013]
FIG. 1A is a perspective view for explaining an outline of a void-type high-rise building according to an embodiment of the present invention. 1B and 1C are a cross-sectional view taken along line AA and a cross-sectional view taken along line BB in FIG. 1A, respectively.
The void-type high-rise building 1 according to the embodiment of the present invention is a multi-storey high-rise building in which a ground portion having a substantially square outer shape in plan view is constructed by four side walls 9, and a void space 2 (open space). , A window void 3 (side open space) and a window void 4 (side open space). The void-type high-rise building 1 may be used for any purpose such as office use and commercial use. However, in the present embodiment, as an example, description will be made assuming that it is used for an apartment house.
[0014]
The void space 2 is a space which is divided into a substantially square shape at the center of the plane of the void type high-rise building 1 and penetrates from the first floor to the roof. Therefore, lighting from the rooftop and outside air can be freely entered and exited.
The void space 2 may have a horizontal boundary partitioned by, for example, a wall or a partition member, or may have a minimum area of an opening defined by a floor slab, a beam, a column, or the like, as shown in FIG. Between the spaces, a wide space may be formed so as to communicate with the inside of the void-type high-rise building 1. In the case of the present embodiment, a corridor space 8 surrounding the void space 2 is provided at an end of the floor slab of each floor, and the corridor space 8 communicates with the void space 2.
In the void space 2, a structure such as a crossing passage may be provided in a range that does not hinder necessary lighting or ventilation.
[0015]
The window void 3 has a vertically long opening 3a extending over a plurality of floors at the center in the width direction of each of the side walls 9 on the upper floor side, and as shown in FIG. And the space communicated with the void space 2 by the opening 3d. The window voids 3 have the same size, and the window voids 3 provided on the side walls 9 opposed to each other are provided at positions where the respective openings 3b are directly opposed.
[0016]
Boundary surfaces are formed above and below the window void 3 by floor slabs (not shown) of the void-type high-rise building 1.
On the other hand, a window void side 3c that forms a horizontal boundary of the window void 3 is defined by ends of the dwelling units 6 facing each other. The interior of the dwelling unit 6 is provided with columns 5, walls 7, and the like, and is appropriately partitioned. What is shown as the window void side 3c is the end of the floor slab of the dwelling unit 6 and the position of the pillar 5 provided thereon. Depending on the type of the dwelling unit, the end of the dwelling unit 6 is provided with, for example, an outer wall surface, a veranda, and a terrace. For this reason, the window void side 3c is not always formed with a wall. Although not shown, a common space such as a plaza may be provided in place of the dwelling unit 6 so as to communicate with the window void 3.
[0017]
A beam 3b joined to a beam (not shown) below the floor slab of the dwelling unit 6 is erected between the window void side portions 3c and 3c facing each other to form a frame structure. Since there is no member between the beams 3b that hinders light transmission or ventilation, such as a floor structure, sunlight or wind entering from the opening 3a or the void space 2 can be freely transmitted.
[0018]
The window void 4 has a vertically long opening 4a extending from the first floor to a plurality of floors at the center in the width direction of each of the side walls 9 on the lower floor side, and as shown in FIG. 1 is a space that penetrates into the inside 1 and is communicated with the void space 2 by an opening 4d. The positional relationship of each window void 4 in plan view is the same as that of the window void 3.
However, unlike the case of the window void 3, the horizontal boundary of the window void 4 is formed by the window wall 10 in which all the walls are vertically continuous. In the window void 4, no structural member, for example, a structural member such as a floor, a beam or a column is provided.
[0019]
Next, the operation of the void-type high-rise building 1 will be described.
By providing the window voids 3 and 4, when wind is blown from the lateral direction, the air flows in from one of the openings 3a and 4a, passes through the window voids 3 and 4, and exits the openings 3d and 4d. By passing up and down in the void space 2 or passing through the window voids 3 and 4 on the opposite side, it is possible to pass through the void-type high-rise building 1 and to the outside. For this reason, fresh air is circulated in the void space 2 to improve ventilation, and when a part of the window void 3 communicates with the inside of the void-type high-rise building 1, the inside of the void-type high-rise building 1 Fresh air is circulated as well.
[0020]
Since the openings 3a, 3d, 4a, 4d of the window voids 3, 4 facing each other are opposed to each other to form a straight flow path, the flow of the wind is smooth and the wind resistance to which the building is subjected Can be reduced. As a result, there is also an advantage that a so-called building wind which wraps around the building and generates a strong wind can be reduced.
[0021]
Further, since the window voids 3 and 4 have the vertically long window voids 3a and 4a, the sunlight easily enters even if the incident angle of the sun changes depending on the season. As a result, there is an advantage that the daylighting performance can be remarkably improved as compared with the case where daylighting is performed from the roof side of the void space 2, and good daylighting performance can be obtained throughout all seasons. In particular, since the window void 4 is provided from the first floor to the upper floor side, there is an advantage that the first floor where the sunlight hardly reaches the normal void space 2 can sufficiently receive light.
[0022]
Thus, according to the void-type high-rise building 1, it is possible to improve daylighting and ventilation, so that the void space 2, which tends to be dim like the bottom of a well, regains brightness by natural light and is refreshing. Since natural winds are distributed, trees and the like also grow well, and there is an advantage that an attractive space full of natural flavor can be formed in the void space 2.
[0023]
By the way, the window voids 3 and 4 can change the rigidity of the building by providing a frame structure including the beam 3b and the window wall 10 in each of the insides or boundaries. For example, if the widths and heights of the openings 3a, 4a are the same, the rigidity (horizontal rigidity) of the building with respect to the horizontal load is higher in the hierarchy in which the window voids 3 are provided than in the hierarchy in which the window voids 4 are provided. Becomes smaller. Further, if the beam 3b in the window void 3 is removed, smaller rigidity can be obtained. Further, if a beam is erected in the horizontal direction of the window void 4, the rigidity can be further improved. In the present embodiment, the layer having no opening occupying the middle between the window voids 3 and 4 has a middle rigidity of the horizontal rigidity of the layer having the window voids 3 and 4.
[0024]
Then, by arranging, in order from the upper floor side where the horizontal rigidity may be reduced, a layer provided with the window void 3, a layer not provided with the opening, and a layer provided with the window void 4, the high-rise building 1 is provided. The horizontal rigidity may decrease from the lower floor toward the upper floor. Therefore, the void-type high-rise building 1 is a building having a reasonable balance of horizontal rigidity such that the horizontal rigidity decreases from the lower floor side to the upper floor side while the outer circumference has substantially the same plane. can do. Therefore, it is possible to reduce the construction cost by rationally arranging the structural members without making the space on the lower floor side excessively large and reducing the space.
[0025]
Moreover, as shown in FIGS. 1B and 1C, the adjustment of the horizontal rigidity can be realized by making the layers having the window voids 3 and 4 into planes of the dwelling unit 6 having exactly the same size and structure. Things. Therefore, many dwelling units having the same plane can be provided, which is extremely convenient as a void-type high-rise building for an apartment house.
[0026]
The window wall 10 gives the window void 4 a high horizontal rigidity. A particularly preferable effect can be obtained by providing the side-open space provided on the lower floor side of the building with the window wall 10 capable of improving both the lighting property and the horizontal rigidity in this way. .
[0027]
Next, a modified example of the present embodiment will be described.
FIG. 2A is a plan sectional view illustrating a first modification of the void-type high-rise building 1 according to the present embodiment. FIG. 2B is a plan cross-sectional view for explaining the second modified example. These plan cross-sectional views are examples of plan cross-sectional views of an arbitrary floor of a floor provided with a side vault space, and a plurality of floors having such a plane are vertically adjacent to each other, and as a result, , And has a vertically long opening like the window void 3 or 4.
[0028]
In the first modified example, as shown in FIG. 2A, a window void 11 is provided instead of the window void 3 or 4.
The window void 11 has a horizontal boundary formed by the window wall 10. However, unlike the window void 4, the width of the openings 11a and 11d is widened between a plurality of columns. In particular, in the present modified example, the width is substantially equal to the width of the void space 2.
According to such a configuration, it is possible to provide a side vent space larger than the window void 4, and the wind resistance and the horizontal rigidity of the building are reduced. In this manner, the side vent space has an advantage that the lighting properties, ventilation, and horizontal rigidity can be appropriately adjusted by changing the width of the opening.
[0029]
As shown in FIG. 2B, the second modified example includes a window void 13 instead of the pair of window voids 11 facing each other in the first modified example.
The window void 13 includes a hollow space 15, a window frame 14, and a hollow space 15 in the width direction of the opening 13 a in this order.
The window frame 14 has a frame structure in which the beams 14a and the columns 14b are joined in a lattice shape. On the opening 13d, the beams 14a and the columns 14b are shared as beams and columns at the ends of the corridor space 8. I have. Since the window frame 14 has a frame structure and does not have a floor structure, sufficient daylighting and ventilation are ensured.
[0030]
In addition, the window void side 13c and the window frame 14, which are defined by the end of the dwelling unit 6 and form a horizontal boundary in the window void 13, are joined by beams and columns of the corridor space 8 on the opening 13d side. There is only one. Therefore, hollow spaces 15, 15 are formed in the lateral direction of the window frame 14.
[0031]
According to the window void 13, since the structural members except the opening 13d are not erected between the window void side portions 13c, the horizontal rigidity of the building is small, but the corridor space 8 is supported by the window frame 14. Has become possible. Therefore, it is not necessary to provide a structural member such as a wall, a thick pillar, or a beam that closes the opening 13d, so that the corridor space 8 can be supported without impairing lighting or ventilation.
[0032]
In addition, in the present modification, since the inside and the boundary of the side vault space are provided with the window voids 11 and 13 which are different from each other, it is possible to change the environment such as daylighting and ventilation, depending on the direction, so that various living spaces can be provided. There is an advantage that it is possible to produce the effect and to make the appearance of the building rich in change.
[0033]
In the above description, the side vent space is arranged in a cross shape in the plane direction. However, if necessary lighting or ventilation can be obtained, for example, a pair of opposed side walls 9 may be provided. May be provided only linearly.
[0034]
Further, for example, when one of the side walls 9 faces the north side, a side-by-side space may not be provided on the north side, and a T-shape in plan view may be employed. By doing so, there is an advantage that the cold north wind can be prevented from blowing into the void space 2 and the inside of the void-type high-rise building 1 without hindering the lighting.
[0035]
In the above description, the members that form the frame structure in the side vault space, such as the beams 3b, the beams 14a, and the columns 14b, may be used in a void-type high-rise building if the frame structure having the required rigidity is formed. It may have the same structure as the beams and columns constituting the main body, or may have different structures.
[0036]
【The invention's effect】
As described above, according to the void-type high-rise building of the present invention, sufficient lighting and ventilation can be obtained, and the horizontal rigidity of the building can be rationally designed in a well-balanced manner in the vertical direction. Play.
