Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a frame structure of a high-rise building in which a high-rise building is made plate-like and the degree of freedom of floor plan (free plan, large span, etc.) is improved, and is widely used mainly in apartment buildings and office buildings. It is.
[0002]
[Prior art]
For example, in the case of apartment houses, it is possible to arrange dwelling units facing all rooms south by shortening the span between beams and making the planar shape as flat as possible. Yes, there are many requests for architectural planning.
[0003]
By the way, the deformation of the building can be separated into shear deformation and bending deformation. For example, in the case of a plate-like high-rise building as shown in FIG. 4B, if the tower ratio (H / D) becomes large, the column The overall bending deformation of the building caused by the expansion and contraction of the shaft tends to increase.
[0004]
For this reason, when a plate-like high-rise building is planned with a conventional rigid frame structure and a rigid frame structure combined with a seismic wall, the overall bending deformation increases with respect to horizontal forces such as seismic loads and wind loads. There were problems such as being too large to ensure sufficient safety and comfortable living.
[0005]
In addition, in the ramen structure that also uses a seismic wall, if the seismic wall is not arranged in a well-balanced plane, not only is there a problem that the building tends to be twisted due to a rigid eccentricity that deviates from the center of gravity of the building, There were problems such as the plan plan being greatly restricted by the arrangement of the earthquake resistant walls.
[0006]
The present invention was made in order to solve the above-described problems. A high-rise building frame structure that can improve the plate-like shape of a high-rise building and the freedom of floor plan (free plan, large span, etc.). The purpose is to provide.
[0007]
[Means for Solving the Problems]
Tube frame construction of high-rise building according to claim 1 is that a plurality of tube frame assembly constructed in a tube shape by arranging a plurality of columns and floor beams on the outer periphery adjacent the digits bound direction arranged adjacent As columns between the frames, columns that are continuous from the lowest floor to the highest floor and columns that are continuous from the lowest floor to the middle floor are arranged.
The tube frame is constructed in a substantially square tube shape (cylindrical shape) by arranging columns and beams on each floor only on the outer periphery, and the three-dimensional effect of the force and the orthogonal (out-of-plane) frame is actively applied to bending resistance. By using it, the rigidity is much higher than that of a normal frame structure, and particularly the strength against bending deformation can be remarkably increased.
As the planar shape of the tube frame in this case, other polygonal shapes such as a pentagon, a hexagon, and an octagon can be considered.
[0008]
In this case, the column and the beam on each floor can use a conventionally used structure type such as an S structure, an RC structure, an SRC structure, or a CFT structure, and a flat slab, Void slabs or synthetic slabs can be used.
[0009]
The high-rise building frame structure according to claim 2 is characterized in that in the high-rise building frame structure according to claim 1, the tube frame structure is arranged in a single-letter shape or a labyrinth shape in the direction of the beam. is there.

[0011]
The structure of a high-rise building according to claim 4 is the structure of a high-rise building according to claim 1, 2 or 3, wherein a column that continues from the bottom floor to the top floor as an outer peripheral pillar, and a floor from the bottom floor to the middle floor It is characterized by arranging continuous columns up to .
[0012]
Rather than having all the columns be continuous from the lowest floor to the top floor, some columns are continuous from the lowest floor to the middle floor, so there are no columns on the upper floors A wide living space can be secured, and a large opening can be provided in the outer periphery. In this case, which columns are to be arranged in this way may be determined based on the plan of the building and the design load.
[0013]
The frame structure of a high-rise building according to claim 5 is characterized in that axial force columns are arranged in the frame structure of the high-rise building according to claim 1, 2, 3 or 4. The axial force column in this case can be arranged particularly when the floor area is relatively large, thereby preventing vibration and deflection of the floor slab and enhancing the comfortability.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
1 (a), (b), and (c) show an example of the structure of a high-rise building according to the present invention. In the drawing, the tube frame 1 having a substantially square shape in the plane is composed of 3 units in the carry direction. They are arranged continuously in a single character.
[0015]
The tube frame 1 referred to here is constructed in a substantially square tube shape (cylindrical shape) by arranging the columns 2 and the beams 3 on each floor only on the outer periphery, and the columns 2a and beams 3a between adjacent units are particularly It also serves as a column and beam for two adjacent units.
[0016]
In addition, the pillars 2 and 2a of each unit are arranged at predetermined intervals according to a design load such as an assumed seismic load, and are arranged in a smaller span than a normal building column span. Rigidity is much greater than the structure, and it is particularly resistant to bending deformation.
[0017]
Furthermore, as shown in FIG. 1B, the pillars 2a between the units are not all arranged continuously from the lowest floor to the highest floor, but some of them are continued to the middle floor. There is no pillar on the floor above it, and a large living space is secured on the floor without the pillar 2a. In this case, which column 2a is used as the middle floor is determined based on the plan of the building and the design load.
[0018]
If the columns 2 arranged on the outer periphery of each unit are also structurally possible, it is not necessary that all the columns 2 are arranged continuously from the lowest floor to the highest floor, and some of them are arranged up to the middle floor. The pillars may not be on the upper floor. Thereby, a large opening can be provided. Moreover, an upside-down beam can be used for the beam 3 on each floor, except for the beam 3a between the units.
[0019]
Further, in this case, structural members generally used such as S structure, RC structure or SRC structure are used for the columns 2 and 2a and the beams 3 and 3a of each floor, and a flat slab or a floor slab of each floor is used. Synthetic slabs are used.
[0020]
If the floor area is relatively large and vibration and deflection are a concern, for example, as shown in FIG. 1 (c), the axial force column 4 that bears only the floor load of each floor as required. A small beam 5 is used, and seismic isolation devices (not shown) may be used on the foundation, intermediate floor, or top floor. As the seismic isolation device in this case, for example, a conventionally known device such as a laminated rubber, a lead damper, or an oil damper can be used.
[0021]
In such a configuration, since each unit is constructed with a tube frame having a large bending rigidity, the bending rigidity of the entire building is large, and thus a high-rise building can be made plate-like.
[0022]
2 (a) and 2 (b) show another example of the present invention. In the drawing, the tube frame 1 having a substantially square shape in the plane is arranged in a continuous manner in a single letter shape in the direction of the beam. . Moreover, the pillar 2a between two adjacent units in the center is continuously arranged only up to the middle floor, and a large living space without the pillar 2a is secured on the upper floor as shown in (b). Yes.
[0023]
3 (a) and 3 (b) show another example of the present invention. In particular, FIG. 3 (a) shows that the tube frame 1 has three units, which are continuous in the direction of the spar, and adjacent units are connected to each other. This is an example in which the beams are arranged in a lame manner while being shifted in the direction between the beams (span).
[0024]
FIG. 3 (b) shows an example in which the tube frame 1 is arranged in a substantially V-shape in a plane, in which three units are continuous in the direction of shift and the central unit and the units on both sides thereof are shifted in the span direction. Is shown.
[0025]
In any of the examples, each unit is constructed of a tube frame having a large bending rigidity, so that the bending rigidity of the entire building is large, and thus a high-rise building can be made plate-like.
[0026]
【The invention's effect】
The invention of the present application is as described above, and in particular, since a plurality of highly rigid tube frames are arranged continuously in the direction of siding to resist horizontal force, the bending rigidity of the entire building is very large, Therefore, even in a plate-shaped high-rise building, it is possible to make a high-rise building into a plate shape without using a method such as increasing the cross section of the column.
[0027]
In addition, the tube frame is constructed in the shape of a flat rectangular tube with pillars and beams on each floor arranged in a birdcage shape on the outer periphery, so the torsional rigidity is very large and the torsional deformation of the building can be reduced. .
[0028]
In addition, since the interior of each unit can be made into a column-free space, the plan plan is not affected by the arrangement of the pillars and beams, and the degree of freedom of plan plan (free plan, large span, etc.) is also very high. .
