DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the large-span structure building of this invention is explained in full detail using FIGS. The present invention is a structure in which a large-span structure that largely spans existing facilities and obstacles is formed, and an upper building that can be built by a normal building plan is constructed on the upper structure.
[0010]
As shown in FIG. 1, a large span structure building 1 is composed of a large span structure 2 and an upper building 3, and the large span structure 2 is a pair of large span portal ramen structures 4. And the orthogonal beam 5.
The large span portal frame structure 4 includes a column unit 7 that is spaced apart in a pair and a large span beam 6 that is horizontally disposed to connect the column unit 7, and the large span beam 6 includes: The beam formation is formed larger than the beam used for the upper building 3 so that it can bridge a large span while receiving the load of the building 3.
[0011]
A pair of column units 7 connected by the large-span beam 6 includes a column 8 and a connection beam 9. A plurality of the columns 8 are spaced apart from each other on the same axis as the large span beam 6, and the adjacent columns 8 are connected by the plurality of connecting beams 9. In the present embodiment, the plurality of pillars 8 are spaced apart from each other only in the direction in which the large span beam 6 is located. However, the present invention is not particularly limited to this, and when the member thickness of the large span beam 6 is large. The plurality of pillars 8 may also be arranged in a direction orthogonal to the large span beam 6, and the pillar unit 7 constitutes a so-called mega pillar.
[0012]
As shown in FIG. 2, the pair of column units 7 are arranged so as to be widely straddled across a part of the site, and by providing a large-span beam 6 so as to connect them, a large-span portal ramen is provided. A structure 4 is constructed. Further, as shown in FIG. 1, the large span portal ramen structure 4 is arranged in parallel and spaced apart in parallel across a part of the site so that the columns facing the large span portal ramen structure 4 are opposed to each other. A large span structure 2 is formed by providing a plurality of orthogonal beams 5 so as to connect the units 7 and the large span beams 6 to each other.
[0013]
In addition, as shown in FIG. 1, the earthquake-resistant wall 10 is arrange | positioned in the outer wall located in parallel with the said orthogonal beam 5 which comprises the said large span structure 2, and the framework by the orthogonal beam 5 and the column unit 7 is used. Together, it is integrated like a single plate, increasing the rigidity and strength against the load and having a high resistance to the wall plate direction. In addition, by forming the so-called multi-story earthquake-resistant wall 11 in a direction perpendicular to the large span beam 6 by connecting the earthquake resistant wall 10 in the vertical direction, the earthquake-resistant safety in the direction perpendicular to the large-span portal frame structure 4 is obtained. The sex is secured.
[0014]
The large-span structure 2 having such a configuration has a plane surrounded by the large-span beam 6 supported by the column unit 7 and the orthogonal beam 5 as viewed from above, and apparently a part of the site. It will have a function as an artificial ground provided on the upper side across a large area. For this reason, the said upper building 3 provided in the upper part of this large span structure 2 can use the building by a normal design plan.
[0015]
In the upper building 3, the outer wall in the direction orthogonal to the large span beam 6 constituting the large span structure 2 is the same in the vertical direction as the outer wall located in parallel to the orthogonal beam 5 of the large span structure 2. It is constructed so as to be located on the axis, and the seismic wall 10 is used. This increases the rigidity and strength in the direction perpendicular to the large-span beam 6 as in the case of the large-span structure 2 and, as shown in FIG. 3, from the large-span structure 2 to the uppermost floor of the upper building 3. The seismic wall 10 is continuously provided on the same vertical axis, and the multi-layer seismic wall 11 is formed to ensure seismic safety.
[0016]
In the present embodiment, the multi-layer seismic wall 11 is provided on the same axis on both sides of the outer side surface and the inner side surface of the column unit 7 to form a double multi-layer seismic wall 11. The multistory earthquake-resistant wall 11 may be provided only on the outer surface side, not particular.
[0017]
In the present embodiment, the orthogonal beam 5 that connects the pair of large-span portal frame structures 4 is joined to the vicinity of the lower portion of the large-span beam 6. Therefore, as shown in FIG. 3, the floor 3 a on the lowest floor of the upper building 3, which includes the orthogonal beam 5 that connects the large span beam 6, is a beam of the large span beam 6. Since it is located lower than the building, it has a function as a balcony or a corridor parapet provided outside the room on the lowest floor of the upper building 3 above the large span beam 6.
[0018]
According to the above-described configuration, the function of bridging a large span so as to largely straddle a part of the site is concentrated in the large span structure 2, and the large span structure 2 is regarded as an artificial ground. Since it is not necessary to add an unnecessary height to the object 3 by increasing the beam construction, it is possible to apply a normal architectural plan, and it is possible to improve the workability and reduce the cost significantly. It becomes.
[0019]
In addition, since the upper building 3 can be applied with a beam having a general beam structure, it is possible to maintain the value of the large span structure building 1 itself without damaging the indoor environment.
[0020]
Since the earthquake resistant wall 10 is used for the outer wall in the direction parallel to the orthogonal beam 5 in the large span structure 2, the rigidity and strength in the direction orthogonal to the large span beam 6 can be increased.
[0021]
The outer wall located in parallel with the orthogonal beam 5 of the large span structure 2 in the upper building 3 is on the same axis in the vertical direction with respect to the outer wall located in parallel with the orthogonal beam 5 of the large span structure 2. Since the continuous multi-layer earthquake resistant wall 11 is formed on both outer walls from the large span structure 2 to the uppermost floor of the upper building 3, the seismic safety of the large span structure building 1 itself is improved. It can be secured.
[0022]
