DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a huge building, and more particularly to a huge building in which a huge space truss is used as an infrastructure and a building is provided in its internal space.

[0002]

2. Description of the Related Art At present, large cities have many problems such as soaring underground, traffic congestion, and environmental degradation. In order to solve these city problems, large cities are provided with various city functions and are themselves one city. There is a plan to construct a huge and high-rise building like this. And, for example,
A super-high-rise building with a height of 1000m and a height of 4000
There has been proposed a building consisting of a huge mountain-shaped frame as large as m.

[0003]

The construction of such an ultra-high-rise building has the following problems.

[0004] That is, there is a problem that, in order to support a super-high-rise building, first, a large area of the lower part thereof, particularly a large base area, is controlled. For this reason, a vast ground level is required. In addition, it is necessary to add or newly develop a sufficient seismic function as an earthquake countermeasure. Further, in order to give the building itself sufficient strength, each component and the like naturally become huge, and the construction period requires an extremely long time. In addition, since the cross-sectional area of a super-high-rise building naturally becomes large, the inside of the building is particularly located far away from the outside world, and there is a disadvantage that it is extremely difficult to take in natural light and natural wind.

The present invention has been made in view of the above circumstances, and can eliminate the above-mentioned drawbacks at a glance. The purpose is to provide a huge building whose location can be selected relatively freely.

[0006]

The invention according to claim 1 is
A giant space truss unit configured with diagonal members, horizontal members, and nodes formed at the intersections of these diagonal members and horizontal members, and a building built in the internal space configured by the space truss unit A huge structure comprising:
The building is characterized in that at least its upper and lower sides are supported by required nodes of the space truss unit. The invention according to claim 2 is the huge building according to claim 1, wherein the space truss unit is

The upper and lower nodes respectively located at positions opposing each other with the plane interposed therebetween, and a diagonal member extending from the upper and lower nodes toward each of the horizontal distribution nodes, and the building has at least the upper and lower sides thereof. The three-dimensional truss unit is supported by the upper and lower nodes. According to a third aspect of the present invention, a space truss is formed by connecting a plurality of the space trusses in the three-dimensional direction with the space truss according to the second aspect as one unit, and an arbitrary space truss constituting the space truss. The building is constructed inside the unit. According to a fourth aspect of the present invention, in the huge building according to the third aspect, the space truss is formed in a pyramid shape as a whole.

[0007]

In the huge building according to the first aspect, since the building is supported at least up and down by the structurally solid space truss unit, the structural reliability of the building becomes extremely high. The structure can be simplified even when the super-high layer is used.

[0008] In the huge building according to the second aspect of the present invention, by making the space truss unit a general shape, efficiency in design, manufacture and construction can be improved.

In the huge building according to the third aspect, the building exists in a three-dimensional direction. For this reason,
It is possible to guide sunlight and natural wind to the inside of a huge building.

[0010] In the huge building according to the fourth aspect, the load is effectively dispersed in the low-rise portion, and the space truss constituting the huge building can be constituted by substantially the same members.

One ring is formed by the eight segments 11. The segment 11 is made of GFRP (glass fiber reinforced plastic). Each segment 11
Has a thickness of about 1 m, has a hollow interior, and is filled with compressed air of at least 2 atm. Then, by connecting these segments 11 in a ring shape as shown in FIG. 3, the outer plate 11a and the inner plate 11b constituting the segment 11 constitute a double pipe. . In this case, the thickness of each of the outer plate 11a and the inner plate 11b is about 25 cm.

As shown in FIG. 5, a titanium alloy plate 12 or a reinforced glass or reinforced plastic constituting a Fresnel lens is provided outside the sphere formed by these segments 15 with a gap of about 1 m therebetween.

The building 3 is constructed in the interior space of the truss unit 10 as described above. In this embodiment, the height of one building is about 500 m (about 100 stories). I have. As shown in FIG. 2 or FIG. 6, the lower part of the building 3 is supported by a node 7 b at the lower part of the truss unit 10 via a support shaft 17, and the upper part is the same three-dimensional truss unit via the support shaft 17. 1
0 is supported by the node 7b above.
In this case, the support shaft 17 is provided so as to penetrate the building 3 and forms a core of the building 3.

Then, as shown in FIG.
Are provided on an arbitrary one of the multiple truss units 10, 10,... Formed by the space truss 2. However, it is of course possible to provide the building 3 in correspondence with all the truss units 10, 10, ... formed by the three-dimensional truss 2. These buildings 3
Like general buildings, they are used as residential or office or leisure facilities.

In this embodiment, four tubes 19 having an outer diameter of about 5 m are provided adjacent to each other inside the diagonal member 6, as shown in FIG. In this case, of these four tubes 19, two opposing tubes 19A and 19C are tubes for elevator construction, one for the up line and the other for the down line. One tube 19B of the other two tubes 19 is, for example, a tube for equipment provided with piping and power distribution, and the other tube 19D is, for example, a distribution tube for transporting materials and the like. Has become. These four tubes 19 are made of GFRP similarly to the segments 11 constituting the diagonal member 6, and as shown in FIG. In contact with the inner surface.
That is, these four tubes 19 also function as reinforcing members for the diagonal members 6.

As shown in FIG. 4, the inside of the horizontal member 5 has a cross section of 6 mm by the reinforcing structure 14.
It is configured to be divided into two sections. That is, in this case, the reinforcing structure 14 is provided horizontally corresponding to the diameter portion of the outer tube 13, and a horizontal center partition 14 a that divides the outer tube 13 into two upper and lower parts, An upper partition 14b and a lower partition 14c provided in parallel with the horizontal central partition 14a, and the horizontal central partition 1
4a and a vertical central partition 14d provided between the upper partition 14b and the lower partition 14c. As a result, the interior of the outer tube 13 has six chambers 2.
, 1, 21,... These six rooms 21
For example, as shown in FIG. 7, the uppermost chamber 21A is used, for example, as a cable laying passage for power distribution and communication, and the lowermost chamber 21F is used, for example, as a piping passage. In addition, in the rooms 21D and 21E constituting the first layer of the upper and lower two layers in the center, an up line 22 and a down line 23 of the traffic network are respectively formed. Further, the chamber 21B constituting the second layer
And a moving walkway 24 in one room 21B of the rooms 21C.
However, a material transport system 25 is formed in the other chamber 21C.

In each of the nodes 7, there is a traffic network or a distribution network, which is formed inside the horizontal member 5.
Various terminals, stations, and the like are configured as intersections between the facility network, the elevator and the distribution network configured inside the diagonal member 6, or the facility network. Further, a truss unit 1 having at least the building 3 therein.
For example, six nodes 7 constituting 0 are 1 of them.
One is provided with an energy supply source (for example, a power plant) for supplying to the building 3, the other is provided with a water supply and treatment facility, and the other is a processing of unnecessary substances discharged from the building 3. It is configured to have facilities and the like. In other words, each building 3 and the truss unit 10 having the building 3 can constitute an independent and complete living environment system by themselves.

In this embodiment, as shown in FIG. 6, the truss unit 10 is constructed, and some of the four horizontal distribution nodes 7a located on the same plane are used as the truss unit. An access 26 is installed substantially horizontally toward the building 3 of the unit 10. By the access 26, the building 3 can be directly entered and exited from the horizontal distribution node 7a without passing through the upper and lower nodes 7b and 7b.

In FIG. 1, reference numerals 30, 30,... Indicate buildings constructed corresponding to the first layer of the space truss 2. These buildings 30, 30, ...
Is provided on the outer periphery of the space truss 2 having particularly good sunshine conditions, and is used particularly for residential use. However,
In the present embodiment, these buildings 30 are
It is formed between the diagonal members 6, 6 of the book, and has a different configuration from the above-mentioned buildings 3, 3,... Supported by upper and lower nodes 7b, 7b.

The operation and effect of the huge building having the above-described structure will be described below. In the huge building 1, the space truss 2 functions as a so-called infrastructure of the building.

In the huge building 1, the space truss 2 may be constructed first, and then the buildings 3, 3,... May be constructed inside the truss unit 10 constituting the space truss 2.

Truss unit 1 composed of space truss 2
0 is many. Therefore, all the truss units 10, 10,...
Can be constructed, or the building 3 can be constructed only on some arbitrary truss units 10.
Therefore, the huge building 1 is composed of each truss unit 1
It is also possible to sell them at every zero. In such a case, in particular, the fact that each truss unit 10 itself constitutes a complete closed system as described above effectively functions. Of course, it is also possible to use a conventional general distribution method, that is, to finely distribute the inside of each building 3.

As described above, since each building 3 can be provided corresponding to each space truss 10, each of the buildings 3, 3,... Can have a different configuration. 8 and 9 show other configuration examples of the building 3. The same components as those in FIG. 1 and the like are denoted by the same reference numerals. The building 3 'shown in FIG. 8 is configured as a quadrangular pyramid as a whole. The building 3 ″ shown in FIG. 9 is configured as an octahedron as a whole.
3 ”also has a truss unit 10 at the top, similar to the building 3 above.
And the lower part is supported by the lower node 7b of the truss unit 10. Further, the building 3 may have a configuration other than those illustrated in FIGS. 8 and 9, for example, a spherical shape.

Further, the huge building 1 has a building 3 inside a space truss 2 as an infrastructure.
Are three-dimensionally scattered in the three-dimensional direction, so that there is a sufficient space inside the huge building 1 that communicates with the outside world. Therefore, in spite of being a huge structure, sunlight and natural wind can sufficiently spread inside, and an extremely comfortable living space that can fully enjoy light and wind can be created.

Further, as described above, the skeleton of the huge building 1 is constituted by the space truss 2, and the space truss 2 is formed in a quadrangular pyramid shape, that is, a so-called pyramid shape. In the space truss having such a configuration, the upper load is dispersed below. Therefore, for example, as an extreme example, even when the building 3 is concentrated on the upper layer of the space truss 2 or is unevenly distributed on the outer periphery of the space truss 2, the knitting loads are effectively dispersed below. However, the structure is strong against such an eccentric load.

Further, since the supporting structure of the building 1 is a space truss as described above, the upper load is widely dispersed in the lower layer, so that the space truss 2 has a structure similar to that of a normal building. The load of the upper layer does not concentrate on the lower layer. Therefore, the space truss 2
The horizontal member 5, the diagonal member 6, and the node 7
It is possible to use those having the same dimensions from the lowermost layer to the uppermost layer of the space truss 2. As a result, it is possible to reduce the manufacturing cost of each of these members and to shorten the construction period of the entire truss unit 2, and it is possible to realize the construction at a shorter period and at a lower cost.

Further, in a truss structure such as the above-mentioned space truss 2, generally, an axial compressive force acts on the diagonal member 6, while an axial tensile force acts on the horizontal member 5.
At that time, the tensile force acting on the diagonal member 6 is as large as several times to ten and several times (absolute value) the compressive force acting on the horizontal member 5. In the diagonal member 6 of the above embodiment, as described above, the inside of the segment 11 constituting the diagonal member 6 is filled with compressed air to effectively prevent buckling due to the strong compressive force. Has become. The compressed air for the node 7 is for the same reason.

The building 1 has a vast bottom area as a whole, but as shown in FIG. 1, only the nodes 7, 7,. Are in contact with each other. Therefore, although the building 1 has such a vast bottom, it does not occupy the whole ground portion with respect to the bottom area, and corresponds to the above-described nodes 7, 7,. You only need to build the foundation on the part. Therefore, in order to construct the above-mentioned building 1, it is only necessary to secure those scattered basic construction parts. For example, it is not impossible to construct the building 1 above an existing city. Moreover, since the entire load of the building 1 is dispersed at the lower portion as described above, each foundation can be small.

Further, with respect to the buildings 3, as described above, each of the buildings 3 is placed at least vertically above and below the truss unit 10 in the internal space of the truss unit 10 constituting the three-dimensional truss 2. It is supported by nodes 7b, 7b. This has the following effects. That is, ordinary buildings are usually supported only by the lower part. Therefore, as the building becomes huge and particularly high-rise, the supporting structure thereof is required to have a strong structure capable of withstanding a huge load or an external force such as an earthquake.
On the other hand, since the building 3 is supported by at least two upper and lower points, the structure of the building 3 itself can be simplified. This is particularly beneficial in the case where the building 3 is a super high-rise building as in this embodiment.

Further, in the building 1, it is possible to connect the building 3 and the horizontal distribution node 7a as shown in FIGS. 6, 8, and 9, for example. Although all of the illustrated examples are connected by the access 26, the access 26 can function as a reinforcing member. In the case of such a structure, the building 3 is supported not only in the vertical direction but also in the horizontal direction, and the structural reliability of the building 3 is further improved. In other words, the structure of the building 3 can be further simplified.

Furthermore, in the building 1, it is naturally possible to add a vibration damping function or a seismic isolation mechanism for the building 3 to the joint between the building 3 and the truss unit 10. Even in such a case, in the building 1 according to the present invention, since there are a plurality of joints between the building 3 and the truss unit 10, that is, since the support load of the building 3 is dispersed, each of the individual structures is controlled. This also allows the vibration and seismic isolation mechanism to be downsized.

Further, in the above embodiment, the building 1
Although illustrated or described as having been constructed on a flat ground, the three-dimensional truss 2 (building 1) can also be used on an uneven ground, or on a ground where a part thereof can reach a hill, for example. It is possible to construct those grounds without leveling them. So, for example,
In the case where a part of the space truss 2 reaches the hill, the structure corresponding to the hill in the space truss 2 is configured to rise from the hill, that is, the space corresponds to the hill. What is necessary is just to make it the shape which a part was notched.

Next, FIG. 10 shows another embodiment of the present invention. The building 1 'shown in FIG. 10 has only one truss unit 10 described in the above embodiment. The other components are the same as those in the above embodiment. However, in this figure, truss unit 1
The illustration of a building constructed inside 0 is omitted.

The essence of the huge building 1 according to the present invention is the truss unit 10 and the building 3 built inside the truss unit 10 and supported by the upper and lower nodes 7b, 7b as described above. The building 1 'shown in the example is a substantial minimum unit of the building according to the present invention. Truss unit 1
0 is not a self-sustainable shape as shown in FIG. 2, and therefore, when a building having only one truss unit 10 is actually constructed, it generally has the form shown in FIG. .

However, the present invention does not limit the truss unit 10 to the above shape. For example, in the truss unit 10, the horizontal distribution nodes 7a may be arranged in another polygonal shape such as a pentagon or a hexagon, for example. In particular, the building according to the present invention is connected to one truss unit 1 as in this embodiment.
When the truss unit 10 is composed of only zeros, the truss unit 10 need not be a general three-dimensional truss (a three-dimensional truss in which the horizontal distribution nodes 7a are arranged in an equilateral triangle or a square) as shown in FIG.

FIG. 11 shows another example of the structure of the building 1 shown in FIG. In this embodiment,
The lowest node 7, 7, ... of the truss unit 2 is the ground 3
1, that is, provided in the ground 32. Accordingly, the lowermost horizontal member 5 also exists in the ground 32, and forms a kind of underground beam. In the figure, reference numeral 33 is a base. The building 1 may be configured as described above.

Further, in the three-dimensional truss 2 of the building 1 shown in FIG. 1 or FIG. 11, the horizontal members 5, 5,. However, a configuration in which these lowermost horizontal members 5, 5, ... are not provided,
Alternatively, it may be configured to be provided only at a required part.

The building 1 according to each of the above embodiments
Although (1 ') shows only a quadrangular pyramid (pyramid) shape, the shape of the huge building according to the present invention is not limited to this. For example, the huge building according to the present invention may be one in which a plurality of the pyramid-like structures as described above are continuously provided, or alternatively, a slope portion (inclined portion) of the pyramid-shaped space truss 2. It may be a compound pyramid shape as if another small pyramid-shaped space truss was set up. Further, for example, it is also possible to make another space truss adjacent to the building 1 shown in FIG.

In the above embodiment, the space truss 2, that is, the horizontal member 5, the diagonal member 6, and the node 7 are G
Although the material is made of FRP or CFRP or the like, the material of the space truss 2 according to the present invention is not limited to these materials, and may be made of other lightweight and high-strength materials.

In the above embodiment, the diagonal member 6
And at the node 7, the inside of each of the segments 11 and 15 constituting them is directly filled with compressed air. However, for example, a large number of rubber bags are provided inside the hollow portions of the segments 11 and 15. Alternatively, compressed air may be filled in these rubber bags. With such a configuration, even if one of the rubber bags is damaged, it is possible to prevent all the compressed air inside the segment from leaking, and the repair becomes easy.

The above-mentioned building 1 (1 ') according to the present invention
In the case where the building 3 is configured to be supported on the truss unit 10 (upper and lower nodes 7b, 7b) only above and below the building 3 as shown in FIG. It is also possible to adopt a configuration of rotating. Further, at that time, the outer wall of the building 3 is formed in a mirror shape, the building 3 is rotated in synchronization with the movement of the sun, and the reflection direction of the sunlight is controlled, so that the reflection is reflected inside the building 1. It can guide light and make the interior of the building brighter.

Further, in the above embodiment, the dimensions of each part have been described as an example, but it goes without saying that the dimensions of each part are not limited to those of the above embodiment.

Further, in the above embodiment, the truss unit 10 has four horizontal distribution nodes 7a.
Although the truss unit 10 according to the present invention has the form of a square arranged at points,
a may be arranged at three points to form a regular triangle.

[0049]

As described above, according to the huge building of the present invention, various excellent effects as described below can be obtained. I. Even though it is a huge building, you can fully enjoy the natural light and wind. B. Although it is a huge building, it is not necessary to occupy the entire ground surface of the construction site, and it is only necessary to construct the foundation scattered only in the portion supporting the space truss. C. It can flexibly adapt to the ground shape, and there is no need to modify the ground surface except for the scattered foundations. Therefore,
There is no risk of destroying the natural environment, and it can be built on existing cities if necessary. D. The building is constructed by the upper and lower nodes of the space truss unit.
Since the structure is supported at least at two points, the structure can be simplified even when the building is a super high-rise building.
Further, the building can be supported in the horizontal direction by the horizontal distribution nodes of the truss unit. In such a case, the reliability of the building inside the truss unit can be further improved. E. In connection with the above d, even when a vibration damping / seismic isolation mechanism is added to a building, sufficient vibration damping / seismic isolation functions are demonstrated because there are multiple support points for the building, The size of the vibration and seismic isolation mechanism can be reduced. F. When a large number of truss units are connected in the three-dimensional direction, and especially when the entire structure is configured as a pyramid-shaped space truss, the load is dispersed below, so that the space truss can be constructed by almost the same member, Short construction period and low cost can be achieved. G. When a space truss unit is constructed by connecting and connecting a large number of space truss units, the truss units can be sold separately. In such a case, each acquirer of the truss unit can construct a free building inside the truss unit. H. The connection form of the truss units, that is, the form of the three-dimensional truss is free, and expansion can be performed freely. Re. Each member of horizontal material, diagonal material, and nodes constituting the truss unit can be used as a person, a distribution route of goods, a distribution terminal, or an energy supply facility.
One truss unit can also constitute a complete living environment system.
