Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a multi-story building classified as a so-called mega structure (super structure).
[0002]
[Prior art]
As shown in FIG. 8, in a conventional general multi-layer building 100, a frame 101 is constituted by a number of columns 102 extending in a vertical direction and a number of beams 103 extending in a horizontal direction. Reference numeral 102 extends vertically through all layers.
[0003]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional multilayer building 100, the existence of many pillars 102 hinders securing a wide free space in the horizontal direction, and there has been a problem that it is difficult to freely change the plan.
[0004]
The present invention has been made in view of the above circumstances, and has as its object to provide a multi-story building capable of securing a wide free space in the horizontal direction.
[0005]
[Means for Solving the Problems]
The invention according to claim 1 is a multi-layer building having a frame composed of columns and beams, wherein a thinning layer of a column is set every other layer or a plurality of layers, and one or more layers adjacent to the thinning layer of the pillar are set. The frame consisting of the pillars and the beams extending in one direction is reinforced by inserting a diagonal material into the structure, and the frame is configured as a giant beam having a beam back of one or more layers, The giant beams are arranged along at least one direction of the plane of the building, and are supported by a vertical structure extending vertically in all layers.
[0006]
In the invention according to claim 2, in claim 1, the giant beam is disposed only along one direction of a building plane, and the vertical structure drags in another direction in the building plane orthogonal to the one direction. It is characterized by being constructed as a wall-shaped body having.
[0007]
The invention according to claim 3 is characterized in that, in claim 2, the vertical structure is disposed at both ends of a building plane.
[0008]
According to a fourth aspect of the present invention, in the first aspect, the vertical structure is constructed as a seismic core having a closed cross section in a central portion of a building plane.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of a multilayer building 1 according to the first embodiment. This multi-story building 1 has a framework composed of columns 6 and beams 7. In this multilayer building 1, a general layer 2 having a normal number of columns every other layer and a free space layer (thinned-out layer) 3 in which the number of columns is extremely reduced from the normal number are provided. Then, the skeleton of the general layer 2 adjacent to the free space layer 3 is strengthened by inserting a diagonal member 8, and the skeleton is configured as a giant truss beam (megastructure beam) 10 having a beam back of one layer. The giant truss beam 10 is supported by a vertical structure 11 extending vertically through all layers.
[0010]
2 is a plan view of the general layer 2 (a sectional view taken along the line II-II in FIG. 1), FIG. 3 is a plan view of the free space layer 3 (a sectional view taken along the line III-III in FIG. 1), and FIG. FIG. 4 is a sectional view taken along line IV-IV of FIG. As shown in FIG. 3, in the free space layer 3, the pillar 6 exists only at the end of the building plane. As shown in FIG. 2, assuming that the vertical and horizontal directions of the columns 6 are the X direction and the Y direction, the giant truss beams 10 are arranged only along the X direction of the building plane, and the vertical structure 11 It is constructed at both ends of the building plane as a wall-like body having a drag in the Y direction.
[0011]
In this multi-story building 1, as shown in FIG. 3, since the free space layer 3 has few columns, a wide free space can be secured. In addition, the frame (megastructure frame) composed of the vertical structure 11 and the giant truss beam 10 resists the horizontal force in the X direction at the time of the earthquake, and both ends against the horizontal force in the Y direction. With the vertical structure 11 in the form of a wall.
[0012]
In the present embodiment, the general layer 2 and the free space layer 3 are set every other layer, but the free space layer 3 may be provided every plural layers. In that case, it is better to form a giant truss beam having a beam back of a plurality of layers.
[0013]
FIG. 5 is a side view showing a multi-layer building 21 according to a second embodiment of the present invention, FIG. 6 is a plan view of the general layer 2 (a cross-sectional view taken along the line VI-VI in FIG. 5), and FIG. FIG. 6 is a plan view (a sectional view taken along the line VII-VII in FIG. 5) of FIG. In this multilayer building 21, a seismic core 22 having a rectangular closed cross section is provided as a vertical structure at the center of the building plane. The giant truss beam 10 is also configured in the Y direction, and the columns 6 are provided only on the outer periphery of the building plane in the free space layer 3. Other than that is the same as the above embodiment.
[0014]
Also in this multi-layer building 21, as shown in FIG. 7, since almost no columns are provided in the free space layer 3, a wide space in the horizontal direction can be secured. The giant truss beam 10 and the seismic core 22 resist horizontal force during an earthquake in both the X and Y directions.
[0015]
Note that the vertical structure may be provided at any position as long as it can reliably support the giant truss beam 10 and does not interfere with securing the space of the free space layer 3.
[0016]
【The invention's effect】
As described above, according to the first aspect of the present invention, a giant truss beam is constructed by inserting a diagonal member into a frame composed of columns and beams extending in one direction, and having one or more layers of beam backs. By providing a giant beam that is along at least one direction of the building plane , the thinning layer of the pillar is set, so that a wide free space in the horizontal direction can be secured in the thinning layer of the pillar, Will allow you to make free plan changes. At this time, the shape and arrangement of the vertical structure supporting the giant beam can be arbitrarily determined as in the second to fourth aspects of the present invention.
