Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight structure composed of a columnar member and a wire, and more particularly to a module suitable for a tensegrity structure.

[0002]

[Prior Art] US R.Bu famous for Geodigic Dome
Tensile-integrity Structures (generally called tensegrity structures) proposed by ckminster Fuller (hereinafter referred to as "Buckminster Fuller") reduce its own weight to the maximum and are flexible structures. The purpose is to be a structure that is independent from the ground. Therefore, it should be noted that the tensegrity structure is not only a lightweight structure, but also that there is no danger of collapse as a whole even against changes in the ground such as an earthquake.

The specific structure of the tensegrity structure is
The elements that construct this, that is, the structural material itself, are compression members and tension members.
And is typically described in detail in US Pat. No. 3,063,521.

When constructing a structure such as a dome with this tensegrity structure, it is known that Edward Popko's "GEO DESICS" (1968, University) in order to improve the heat insulation and the rigidity. of Detroit Pres
s) Fig. 51 and Fig. 52. In these dome structures, a columnar member (compressing member) is used in a portion corresponding to a side of a hexagon, and a wire rod (tension member) is used in a portion corresponding to a diagonal line to form a two-layer tensegrity structure.

On the other hand, there is disclosed a dome structure which is composed of only columnar members (compressing members) without using wires (tension members) and whose wall surfaces are made into two layers (US Pat. No. 4,026,313). . In this dome structure, the columnar members, which are its constituent elements, are made to intersect and are pivotally coupled to each other so that the entire structure can be folded.

[0006]

[Problems to be Solved by the Invention] Edward Popko
"GEO DESICS" (1968, University of DetroitP
The dome structure shown in Fig. 51 and Fig. 52 of ress) requires adjustment using a large number of turnbuckles when installing wire rods and balancing tension during its construction, and There is also a problem that adjustment requires a high degree of skill. In addition, there is a problem that if one portion of the wire is cut, it is easy to lead to the destruction or deformation of the entire structure. Furthermore, since they cannot be folded as a whole, they have problems in productivity, transportability and storability.

Further, in the dome structure of the above-mentioned US Pat. No. 4,026,313, the module itself constituting the structure does not have self-sustainability, and there is no element for stabilizing the structure in the process of construction, so that it is difficult to construct. When is destroyed, it is easy to lead the destruction or deformation of the whole structure. Further, since stress concentrates on the pivot portion of the columnar member, it is easily broken, and since it is composed of only the columnar member, it is necessary to make the columnar member thicker structurally, which makes it difficult to reduce the weight.

Therefore, an object of the present invention is to provide a module having a two-layer structure, which is composed of a columnar member and a wire and has an outer surface and an inner surface separated from each other, and the module itself is structurally self-supporting. To aim.

At least a columnar member that extends radially toward the apex, the free ends of these radial columnar members are mutually connected by a wire rod or a columnar member, and the center poles are connected by a wire rod or a columnar member. Is characterized by.

FIGS. 16 and 17 show a hemispherical dome structure constructed by using the tensegrity structure module of each of the above embodiments, and FIG. 18 shows a dome constructed by connecting two hemispheres. Shows. The dome formed by the tensegrity structure module according to the present invention is a self-supporting structure as a whole, and if it is formed by a foldable module, the whole can be folded. 16 and 17, the columnar member is shown by a solid line and the wire rod is shown by a broken line. As is clear from the figure, the wire material forming the outer periphery of the module is removed, and the region Y is the gain portion.

The all-spherical dome structure shown in FIGS. 19 and 20 is constructed by connecting tensegrity structure modules (hatched portions in the drawings) according to the present invention, but different from the above-mentioned embodiments. Instead of connecting the peripheral poles of the module to each other, the peripheral poles are offset and coupled to the wire material forming the outer periphery of the adjacent module to obtain the gain region Y. According to this example, there is an advantage that the connecting tool shown in FIG. 2 or the like is not required to connect the adjacent modules.

Further, in the construction of each of the above-mentioned embodiments, the columnar members 1, 1 intersecting in the X-shape are pivotally connected, but these are loosely connected by an elastic flexible member such as a rubber band. Alternatively, the columnar members 1 and 1 that intersect may not be connected to each other.

Further, as shown in FIG. 21, the columnar members intersecting between the adjacent poles may be formed in a double magic hand shape as shown in the figure. In this case, of course, three or more stations may be connected.

Although the embodiments of the present invention have been described above, the following modifications are also included, for example.

For example, in the module 10 shown in FIG. 1, six columnar members may be radially extended from the central north pole N0 and three columnar members may be radially extended from the central south pole S0. In this case, each columnar member extending from the South Pole S0 may be arranged so as to straddle it with a pair of columnar members extending from the North Pole N0, or the basic configuration is the same as in FIG. At this point, the ends of the additional three columnar members may be connected to the midpoint of the wire rod 2a forming the outer periphery F of the surface B.

Although the foldability is taken into consideration in the embodiment, the columnar members may be connected by welding or the like if the foldability is ignored. Also,
The wire rod may be appropriately replaced with a columnar member if the tensegrity is not taken into consideration.

[0069]

As described above, according to the present invention,
It is a flat prismatic module, and has columnar members that extend radially from the center of the upper surface and the lower surface toward the apexes of the other surface, and the free ends of these radial columnar members are mutually connected by wire rods or columnar members. Since the central poles are connected to each other by a wire rod or a columnar member, the module is a two-layer structure module composed of a columnar member and a wire rod with an outer surface and an inner surface separated from each other. Independent. Therefore, no skill is required to construct a structure such as a floor or a dome using this module. It also has excellent heat insulation and rigidity, and is easy to transport and store.
