[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an architectural structure, and more specifically, the present invention relates to an architectural structure that is obtained by vertically and horizontally connecting domes formed on one square of a regular hexahedron. [Prior art] Regarding a dome structure that can cover a space of any size up to the dome structure space, and whose unit constituent faces are triangular, there is a dome structure in which the unit constituent faces of the dome are triangular. If the size of one unit of the shape is divided to a size that a human can hold, anyone can construct a stable structure by sequentially connecting the triangular units.

[Problem that the invention attempts to solve]

However, since dome-shaped structures are generally hemispherical or spherical, their vertical projected area is larger (the larger they are, the higher their height will inevitably be, and the dangers associated with their construction will also increase). , equipment such as a hoist is also required,
This poses an extremely large barrier for amateurs to construct domes with large vertical projected areas.

[Means for solving the problems and their effects] The present invention was made in view of the current situation, and even amateurs can use it to cover spaces of arbitrary size, such as storerooms, greenhouses, temporary buildings, etc. The purpose is to provide a dome-shaped architectural structure that can be constructed.

In summary, the architectural structure of the present invention has a circumscribed taste of a regular hexahedron obtained by separating the circumscribed taste of the regular hexahedron by an arc whose chord is the four sides of one regular hexahedron constituting the regular hexahedron. A line segment connecting a point where a perpendicular line passing through the center of gravity of the one-sided square constituting the regular hexahedron intersects the circumscription of the regular hexahedron and each vertex of the one-sided square constituting the regular hexahedron. A first division is made into four middle parts by a circular arc whose chord is , and each of the three circular arcs surrounding a part of the circumscribed area of the regular hexahedron that has been made the first division is divided into three parts, and each division point is The middle part, which has been divided into the first part by a circular arc whose chord is the connecting line segment, is further divided into nine small parts.
The dome-shaped structure obtained by dividing the unit parts into each other and connecting the vertices of the second divided small parts to each other is taken as a unit unit, and the dome-shaped structure of the above unit unit is divided into the front, back, left, and right directions. It is designed to cover a space of any size by connecting it to.

A second division is made to form a dome-shaped structure.

Since this structure is a structure in which the triangular parts obtained by the second division are connected, it is extremely robust against mechanical numbers, and can be constructed by anyone once the distance between each point is determined. You can always get the same structure no matter what.

Therefore, in this embodiment, for example, each of the second divided small parts, that is, four triangular plate-shaped unit bodies formed by point P1, point P6, and point P12, is divided into four triangular plate-shaped unit bodies, which are formed by point P6, point P, and point 2.

Incidentally, FIG. 6 is a plan view showing a state in which three dome-shaped structures of unit units are connected vertically and five horizontally as described above, and FIG. 7 is a front view thereof. If a filling member of the same shape is attached to the gap between the dome-shaped structures of the unit units (the star-shaped portion indicated by diagonal lines in Figures 6 and 7), it is possible to cover a space of any size. Moreover, by lifting the four sides with structural walls or columns, a structure of any height can be obtained.

In addition, when the dome-shaped structures of the unit units are connected vertically and horizontally, as illustrated in Fig. 5 above, the vertically bent portions around the triangular plate-shaped unit bodies, which are the constituent elements of the dome-shaped structure of the unit units, are connected vertically and horizontally. may be fastened with bolts and nuts or other fastening means in the same manner as described above.

Furthermore, in the above example, a set of triangular plate-shaped unit bodies is connected to construct a dome-shaped structure of unit units.

Furthermore, in the above example, the arc whose chord is the line segment connecting points P1 and P2 is divided into three equal parts.
The string connecting point P2 and point P2 may be divided into three equal parts.

In addition, although the size of the dome-shaped structure of the unit unit is not particularly limited in the above description (note that limiting this size is not an essential requirement of the present invention), If you are assuming that you will assemble it personally, for example, point P
The distance between 1 and point P6 is usually several tens of cm to 1 m.
It will be cm.

〔Effect of the invention〕

As explained above, according to the present invention, anyone can reliably construct a dome-shaped structure of unitary units by connecting unitary units such as triangular plates and rod-shaped bodies assembled in advance as instructed. At the same time, it is also possible to cover a space of any size by connecting any number of unit dome-shaped structures constructed as described above vertically and horizontally.

Furthermore, according to the present invention, by constructing a unit dome-shaped structure on a flat ground and then connecting it vertically and horizontally, it is possible to cover a space as large as the size of an appointment, so even if a space with a large vertical projected area is covered. Even in the case of construction, the danger during construction does not increase, and large equipment such as a hoist becomes unnecessary.

Furthermore, the dome-shaped structure obtained by the present invention, whether it is a structure of unit units or a structure of connected unit structures, has an approximately rectangular inner dimension, so it can be used for furniture or other objects. Even when storing equipment, it is possible to use the existing equipment as is.
