Abstract

PROBLEM TO BE SOLVED: To improve the workability of dome construction for cost reduction by constructing a spherical structure which is formed by the combination of hexagonal blocks and pentagonal blocks having curved surfaces and the identical sides. SOLUTION: Half blocks 21 of hexagonal blocks 2 and pentagonal blocks 3 are disposed at the first stage of a foundation structure 1, only the hexagonal blocks 2 are arranged at the second stage, and the block at the first stage and the adjacent block at the second stage are jointed to each other. Both of the hexagonal block 2 and the pentagonal block 3 have curved surfaces which meet designed shapes respectively, therefore, as the blocks are stacked toward the upper stages subsequently, a structure having spherical shapes is formed. All the blocks of two types have the identical shape, thereby attaining easy manufacture and cost reduction. The blocks are not jointed to each other in a narrow space, thus it is possible to conduct efficient jointing work.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dome construction method for constructing a dome structure by combining blocks.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIG. When constructing a spherical structure, a spherical structure is constructed by dividing a block along a meridian V around a pole P, further dividing into blocks along a latitude line H, and combining each block. I was

However, according to this method, the block B1 near the pole P becomes thinner as it approaches the pole P, and the joining work of the adjacent blocks B1, B1 becomes difficult. That is, when the block body B1 is a steel plate, welding distortion occurs. When the block body B1 is a PC plate, it becomes difficult to install a bolt box for joining with bolts and the like, and the joining work is further difficult. Become.

[0004] In addition, it is difficult to manufacture and assemble a large block body simply divided into blocks along the meridian line V. If the block is divided into smaller blocks along the latitude line H, different types of blocks are generated. However, also in this case, the assembling work becomes difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a method of constructing an inexpensive dome with good workability by a simple method. And

[0006]

The present invention relates to a method for constructing a dome, comprising combining a hexagonal block and a pentagonal block having curved surfaces and the same side length to construct a spherical structure. A dome construction method, wherein the pentagonal blocks are combined without being adjacent to each other.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

<A> Overall Configuration FIG. 1 is a developed view showing a method of constructing a dome according to the present invention. On the first stage on the substructure 1, half blocks 21 of the hexagonal blocks 2 and pentagonal blocks 3 are alternately arranged. In the second stage, only the hexagonal blocks 2 are arranged, and in the third stage, the hexagonal blocks 2 and the pentagonal blocks 3 are alternately arranged, and the like. The hexagonal block 2 and the pentagonal block 3 are formed in advance into a curved block having a curved surface that matches the design curvature of the structure. FIG. 2 is a developed view showing a case where the hexagonal block 2 and the pentagonal block 3 in FIG. 1 are interchanged. In either case of FIGS. 1 and 2, the pentagonal blocks 3 are a combination that is not adjacent to each other.
When the hexagonal block 2 and the pentagonal block 3 are a regular hexagon and a regular pentagon, the structure is a sphere, and when the block is a non-regular hexagon and a non-regular pentagon, the structure is a non-sphere, that is, a dome structure. Further, by forming the hexagonal block 2 and the pentagonal block 3 in a vertically long shape, a vertically long structure can be obtained. A bolt joint box having a bolt insertion hole and a female screw for bolt insertion are formed in the joint end surface of each block, and the blocks are joined by bolts.

<B> Blocks The blocks used in the present invention are only two types, hexagonal blocks and pentagonal blocks, and the connection structure, side length, curvature, thickness, etc. are all the same except for the number of squares. Because there is
Only the hexagon block will be described. FIG. 3 is a perspective view of the hexagonal block 2. On each of the six sides, for example, a bolt box 4 or the like of a segment used for shield construction is provided. As the material of the hexagonal block 2, any material such as concrete, steel, glass or the like may be selected according to the purpose of use.

<C> Joint Structure FIG. 4 is a perspective view showing an example of a joint structure between the blocks. A bolt box 4 is provided on one surface of the hexagonal block 2, and a joining plate 6 having a bolt insertion hole 5 is provided on a joining end surface. A bolt insertion hole 7 is formed on one surface of the pentagonal block 3 facing the bolt box 4. The structure for joining the blocks is not limited to the above structure, and any conventional method may be used. That is, a plate may be provided on the end face and welding may be performed. In the case of bolt connection, one-touch bolts may be employed to join the blocks. (Not shown)

[0011]

The method of constructing the dome will be described below.

<A> Construction of Substructure In FIG. 1, a substructure 1 is constructed on the ground to be constructed. When constructing the substructure 1, a half block 21 and a pentagonal block 3 of the first-stage hexagonal block 2 are arranged.

<B> Block Arrangement and Joining Only the hexagonal blocks 2 are arranged in the second stage, and the first-stage blocks and the adjacent blocks in the second stage are joined by an arbitrary method. In the third row, hexagonal blocks 2 and pentagonal blocks 3 are alternately arranged in the same manner as in the first row. Since each block is processed with a curved surface corresponding to the design shape, a structure having a spherical shape is formed as the blocks are sequentially assembled toward an upper stage.

<C> Closing by Top Block FIG. 5 is a plan view of a dome structure according to the present invention. As described above, the hexagonal block 2 and the pentagonal block 3 that have been sequentially assembled toward the upper stage form a spherical shape and are closed by the pentagonal block 3, thereby completing a spherical structure.

[0015]

Since the present invention has been described above,
The following effects can be obtained. <A> Since the blocks constituting the spherical structure are all of two types having the same shape, the manufacturing is easy and the cost can be reduced. <B> Since there is no connection in a narrow place, the connection work between the blocks can be performed efficiently. <C> By making the curve of the block a curve that matches the design shape, it is possible to make a structure with variations. <D> Since the block is manufactured in a factory, a high quality structure can be obtained. <E> Since the blocks are manufactured at the factory, the construction period can be shortened.
