DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skeleton structure of a structure, and more particularly, to a skeleton structure of a structure in which an upper layer of the structure is supported by a huge structure called a so-called megastructure.

[0002]

2. Description of the Related Art In recent years, there has been proposed or provided a structure in which a structure having a multi-story structure is supported on a structure called a so-called megastructure (giant frame). According to this structure, there is an advantage that a large space can be created above the ground by the lower structure, ie, the megastructure, which constitutes the lower part of the structure.

FIG. 3 shows a frame 1 having a so-called megastructure as a lower structure 30 as described above. An upper structure 20 is supported above the lower structure 30 of the frame 1.

The upper structure 20 includes columns 21, 21,...
And the beams 23, 23,... Constitute a normal multi-layer structure skeleton framed by so-called skeleton components. On the other hand, the lower structure (megastructure) 30 includes a truss layer 31 formed at the top and four columns (corner columns) 32 supporting the truss layer 31.

The pillars (corner pillars) 32 forming the lower structure 30 support the load applied by the upper structure 20, so that the columns 21 and 22 forming the upper structure 20 are naturally formed.
The four corner pillars 22 disposed at the corners of the upper structure 20 among the pillars 21 constituting the upper structure 20 are larger than the lower structure 30. Is formed on the upper end of the pillar (corner pillar) 32.

[0006]

By the way, the following disadvantages have occurred in the above-mentioned conventional megastructure structure.

That is, the pillars (corner pillars) 32 forming the lower structure 30 support the load applied by the upper structure 20, and therefore, naturally, the columns 21, 21,... Forming the upper structure 20. As shown in FIG. 4 (plan view), four corner pillars 22 arranged at the corners of the upper structure 20 among the pillars 21 constituting the upper structure 20 have a large diameter. Is placed on the upper end of the column (corner column) 32 that constitutes the lower structure 30. Further, the corner pillar 22 of the upper structure 20 has a beam 23A extending in one direction and a beam extending in a direction different from the beam 23A (usually a perpendicular direction), like a general pillar. And both beams 23B are connected.

However, in the frame 1 as described above,
The axial force of the upper structure 20 flows to the outer pillars due to the Fireendale effect, and the corner pillars 22 also bear a high axial force. Furthermore, the corner columns 22 are subjected to bending in two horizontal directions, that is, both in the x and y directions, both under a vertical load and an earthquake load, so that design conditions are severe.

The present invention has been made in view of the above circumstances, and in a frame structure of a structure as described above having a so-called megastructure in a lower portion, a corner post of an upper structure which bears a high axial force. It is an object of the present invention to provide a frame structure of a structure capable of effectively relaxing the design conditions of the above.

[0010]

The invention according to claim 1 is
An upper structure formed of a multi-story structure by frame constituent members such as columns and beams, and a lower diameter of the lower part of the upper structure than that of the columns constituting the upper structure so as to support the upper structure. In the frame structure of the structure comprising: a lower pillar configured with the pillars of the upper structure, the corner pillars of the upper structure located at the corners of the upper structure, A beam is provided so as to be directly supported on a corner post of a lower structure located at a corner of the structure, and the corner post of the upper structure extends in one direction from the corner post. , And a second column for supporting a beam extending in a direction different from the beam.

According to a second aspect of the present invention, in the frame structure of the structure according to the first aspect, a corner post of the lower structure is formed in a rectangular shape in a horizontal cross section, and the first column and the first column are formed in a rectangular shape. Each of the two pillars is provided diagonally facing the outer surface of a corner pillar of the lower structure.

[0012]

In the frame structure of the structure according to the first aspect, since the corner pillar of the upper structure is constituted by a plurality of (two) pillar members, each pillar member (the first pillar and the second pillar) is formed. ) Can be reduced. Further, only the bending from one direction is applied to the first column and the second column.

[0013] In the frame structure of the structure according to the second aspect, in addition to the above operation, the first column and the second column can be largely separated from each other.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a frame structure 1 according to an embodiment of the present invention.
In this figure, the same components as those shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

The skeleton 10 has a lower structure (mega structure) 30 constituting a lower portion of the skeleton 10 and a structure supported on the lower structure 30 and constructed on the upper portion thereof, as shown in FIG. And the upper structure 20 formed.

A corner post 22 constituting the upper structure 20
Are supported on the upper portions of the corner pillars 32 of the lower structure 30 forming a so-called megastacle, as in the case described above. However, here, the corner post 22 of the upper structure is used.
Are the first column 22a and the second column 2 as shown in FIGS.
2b.

In this case, the corner post 32 of the lower structure is 200
0 mm □, on the other hand, the first column 22 a and the second column 22
b is 600 mm square. And
The first pillar 22a and the second pillar 22b are arranged diagonally facing the outer peripheral portion of the corner pillar 32 of the lower structure as shown in FIG.

Further, as shown in FIG. 2 (plan view), only the beam 23A extending in one direction (x direction) is connected to the first column 22a, and the beam 23A is connected to the second column 22b. In this configuration, only the beam 23B extending in a direction different from the beam 23A (the y direction orthogonal to the x direction in the horizontal plane) is connected.

According to the above structure, the corner post 22 of the upper structure 20 is constituted by a plurality (two) of column members.
Each pillar member (the first pillar 22a and the second pillar 22
The axial force borne by b) can be reduced. Moreover, the first column 22a and the second column 22b have x respectively.
Only bending from one direction or the y direction is applied. Therefore, this allows the first pillar 22
For each of the column a and the second column 22b, a clear analysis can be performed in terms of design, and a rational design of the corner column 22 can be performed. Also, since only the bending in one direction of the x direction or the y direction acts on each of the first column 22a and the second column 22b, the rigidity can be adjusted separately in each of these directions. Become.

By arranging the first pillar 22a and the second pillar 22b on the diagonal of the corner pillar 32 of the lower structure as described above, a sufficient space is provided between both pillars 22a and 22b. An interval is formed, and workability in construction can be secured.

Further, as can be seen from FIG. 2, since the upper structure 20 has no pillars at the corners of the building, it is possible to create a unique space with an open view at the corners, for example, refreshing. It can be used effectively as a room.

Further, by arranging the first pillar 22a and the second pillar 22b on the diagonal of the corner pillar 32 of the lower structure as described above, as can be seen from the comparison between FIG. 4 and FIG. The beams 23A and 23B respectively connected to the first pillar 22a and the second pillar 22b can be brought closer to the outer periphery of the corner pillar 32 of the lower structure, whereby the upper structure of the lower structure 30 can be moved. 20 can be made as small as possible.

[0023]

As described above, according to the first aspect of the present invention, the corner pillar of the upper structure is constituted by a plurality of (two) pillar members (first pillar and second pillar). Therefore, it is possible to reduce the axial force that each column member bears. In addition, since only the bending from one direction is applied to each of the first column and the second column, a clear analysis in terms of design is performed for each of the first column and the second column. This makes it possible to achieve an excellent effect that it is possible to design a reasonable corner post and to adjust the rigidity separately in each direction.

According to the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, since there is no pillar at the corner of the upper structure, the view can be opened at the corner. A unique space can be created. Further, the beams connected to the first pillar and the second pillar, respectively, can be brought closer to the outer peripheral portion of the corner pillar of the lower structure, whereby the size of the lower structure protruding from the upper structure can be made as small as possible. can do. In addition, since a sufficient space is formed between the first pillar and the second pillar, an effect that workability in construction can be secured can be obtained.
