Description

[Detailed description of the invention] (Industrial application field) The present invention relates to the structure of a high-rise residential building.

(Prior art) In recent years, high-rise residential buildings with a so-called double tube structure, in which the outer periphery and internal atrium are provided with double structural surfaces along the inner core part, have become more rational in terms of floor and elevation planning. It has been adopted since.

FIGS. 3 to 6 show examples of such conventional high-rise residential buildings with a double tube structure.

That is, in each figure, the outer peripheral part 1 and the internal atrium have structural surfaces arranged in a tube shape along the part or inner core 2, and are designed to bear the water f force f1 exclusively for the earthquake brim wind pressure. ing.

Therefore, in Figures 3 to 5, beams 3 are provided to bear vertical forces such as fixed loads and live loads on each floor, and in Figure 6, the interior is spaced at predetermined intervals. A so-called void slab 4, which is hollow and has directional properties and can also be used as a beam, is used.

Regarding the processing of the corner portions 5 in FIGS. 3 to 5, in FIG. Small beams 6 are arranged diagonally, and in FIG. 5, a plurality of small beams 6 are arranged in parallel in the same direction at each corner portion 5.

(Problem to be solved by the invention) However, high-rise housing requires a degree of freedom in planning, and from the perspective of converting the interior space into an oven, the floor height should be made as high as possible, and there should be no excess on the ceiling surface. It is desired to suppress the protrusion of beams, etc. as much as possible.

In particular, the corner part 5 occupies an important position from the ten-sided plan, so an open space is required, but as mentioned above, in conventional high-rise housing,
In the example shown in the figure, small beams 6 are also provided at each corner 5, which is more bothersome in appearance than a flat ceiling surface.In order to secure the ceiling height, the floor height must be increased accordingly, which is difficult to design. It is uneconomical, and the provision of the small beams 6 creates a directionality in the load burden, and the stress burden at both ends of the small beams becomes larger than that at multiple parts, resulting in disadvantageous elements in design. was there.

Furthermore, even with the void slab 4 shown in Figure 6, even if the ceiling surface is flat, the slab itself becomes thicker to meet the structural strength, so the floor height needs to be raised. It had drawbacks.

The present invention aims to solve such conventional problems by rationally treating at least each corner portion in terms of structure.

(Step F for solving the problem) In order to achieve the above-mentioned object, the structure of the super high-rise residential building according to the present invention has a tube structure in which at least the corner portions are formed of flat slabs, and the flat slabs are subjected to vertical loads. It is characterized by the provision of support columns.

(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows an embodiment of the present invention, and the super high-rise residential building according to this embodiment is constructed by providing continuous load-bearing walls along the outer peripheral part 1 and the internal atrium part 2 at 21rf. , which has a so-called double duplex structure.

Therefore, in this embodiment, each corner portion 5 of each floor
is formed by a flat slab 10 without a beam, and a vertical load supporting column is installed approximately in the center of the flat slab 10! 1 is arranged to form a pillar support structure.

Note that the vertical load supporting column 11 may be provided with a capital enlarged portion depending on design conditions.

In addition, 3 in the figure is a beam.

In this embodiment having such a configuration, the corner portion 5
By using a flat slab 10 and supporting it with vertical load support pillars 11, the space becomes beamless while keeping the slab thickness thin, making it possible to secure a predetermined ceiling height even if the floor height is low. The height of the plan is increased without restricting the position of the partition due to the small beams, the openness of the space is large, and the commercial value is also increased.

In addition, the In support column just before the lead! can be placed in any position that does not interfere with the floor plan depending on the conditions, and from the viewpoint of openness and freedom of space, capital and q si are desirable.

Further, as in the second embodiment of the present invention shown in FIG. 2, the entire slab of each floor is a flat slab I2 without a beam, and vertical load supporting columns 11 are arranged at arbitrary positions of the slab 12 according to load conditions. It may be configured as follows.

In this embodiment, vertical load support columns 11 are
By providing this at an arbitrary position on the entire slab 12, the degree of freedom in planning and economy are further increased.

It goes without saying that the present invention is not limited to the above-described embodiments, and that various modifications can be made without departing from the gist of the present invention.

(Effects of the Invention) The present invention is configured as described above, and in a tube-structured superhigh-rise housing, at least the corner portions are formed of flat slabs, and vertical load supporting columns are provided on the flat slabs, thereby achieving Rich in spatial openness,
The 1111 degree of the plan is high and it provides housing with high commercial value.
