Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ceiling material for forming a spherical ceiling.

[Conventional technology]

Conventionally, a spherical ceiling is formed by, for example, as shown in FIG. 3, a spherical ceiling material 10 made up of a combination of a large number of ceiling members 6 ... The conventional spherical ceiling material 10 is shown in FIG.
As shown in (b), a flat rectangular ceiling member 6 is used. Slits 7 and 8 vertically and horizontally on the back surface 62 of the ceiling member 6.
Is added to have flexibility, and the surface 61 is bent so that the surface is inward. When the ceiling member 6 is pressed against the base 5, the ceiling member 6 is bent so that its surface 61 is on the inside, and the surface 61 of the ceiling member 6 is made a part of the spherical inner surface. A spherical ceiling is formed by combining a large number of quadrangular ceiling members 6 ...

[Problems to be solved by the device]

As in the prior art, rectangular ceiling members 6 are arranged in the circumferential direction from the lower portion of the spherical underlayer 5 on the surface of the underlayer 5 formed into a smooth spherical surface, and are attached in one row. In the structure in which the rows of the ceiling members 6 are sequentially constructed from the bottom to the top, as the upper surface of the spherical base 5 is approached, the joint spacing between both side edges of the ceiling member 6 is different between the upper and lower side edges. . Therefore, between the left and right ceiling members 6 arranged adjacent to each other, the upper part of the side edge pushes up between the side edges, and the lower part of the side edge causes a gap between the side edges. As a result, the surfaces of the ceiling members 6 are not smoothly connected to each other, and the protrusions and the gaps cause unevenness.

In addition, the trapezoidal ceiling member 6 in which the lengths of the upper side and the lower side are different from each other in accordance with the joint spacing between both side edges between the ceiling members 6 in one row.
By using, it is possible to prevent the push-up and the generation of the gap as described above. However, in this case, the trapezoidal shape required to eliminate the push-up or the gap differs depending on the height position to be installed, that is, the height position of the row of the ceiling members 6, so that the shape and dimension of each row are different. Different ceiling members 6 must be prepared. Therefore, the material cost increases. At the time of construction, it is necessary to select a ceiling member 6 having an appropriate shape from among the ceiling members 6 having subtly different shapes, and to construct it at an appropriate position, which makes the construction work troublesome.

Therefore, this invention requires less types of ceiling members,
Moreover, it is an object of the present invention to provide a spherical ceiling material capable of obtaining an approximate spherical surface formed of a polyhedral surface in which no unevenness is generated between the ceiling members and the surfaces are smoothly connected.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, a spherical ceiling material according to the present invention comprises a combination of a large number of pentagonal members and hexagonal members, and the pentagonal members and hexagonal members are the pentagonal members formed of the hexagonal members. It is supposed that a spherical surface is configured by being attached to and assembled on a spherical base so as to surround and be adjacent to each other at sides.

[Action]

Since the spherical ceiling material is composed of a combination of a pentagonal member and a hexagonal member, it is not necessary to change the dimensions of these ceiling members depending on the position of the spherical surface, and two types of ceiling members can form a spherical surface. Moreover, it is possible to arrange the ceiling members without any gaps, so that there is no unevenness due to a thrust or a gap between adjacent side edges of the ceiling members, and the surfaces of the adjacent ceiling members are smoothly connected, It is possible to construct a spherical ceiling consisting of an approximate spherical surface composed of a polyhedral surface close to a mathematical spherical surface.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

FIG. 1 shows an embodiment in which a spherical ceiling is formed by the spherical ceiling material 1 according to the present invention. In the present invention, the spherical ceiling does not only mean a ceiling having a mathematically exact spherical surface, but also includes a circular ceiling called a so-called dome.

As shown in FIG. 1, a spherical ceiling material 1 according to the present invention
Is made up of a combination of a large number of pentagonal members 2 ... And hexagonal members 3 ..., and is attached to the spherical base 5 with staples or adhesives, for example, radius r = 500 to 5
We are making a 0000mm spherical ceiling. O is the center of the sphere. As the pentagonal member 2 and the hexagonal member 3, mineral fiber boards such as rock wool sound absorbing board and fiber reinforced gypsum board are used, but the material is not limited. Each of the pentagonal member 2 and the hexagonal member 3 is a plate processed so that its surface becomes a part of a spherical surface to be formed, as shown in FIGS. 2A and 2B. Is. With this, it is convenient to construct. Alternatively, the pentagonal member 2 is made as a pentagonal flat plate, and the hexagonal member 3 is made as a hexagonal flat plate, and these members 2 and 3 are bent inward by being pressed against the base during construction, The surfaces 21, 31 may form a spherical inner surface. When the pentagonal member 2 and the hexagonal member 3 are made as flat plates, slits 7, 8 in the vertical and horizontal directions as shown in FIG.
May be provided so that the members 2 and 3 have flexibility.

The pentagonal members 2 ... And the hexagonal members 3 ... Are combined so that one pentagonal member 2 is surrounded by five adjacent hexagonal members 3 ... Like a soccer ball. In Figure 1,
Only one example of such an arrangement is shown, and illustration of other arrangements is omitted. Five sides of the pentagonal member 2 are equal in length to each other and correspond to one side of each of the five hexagonal members 3 ... Therefore, the corresponding sides of the pentagonal member 2 and the hexagonal member 3 are formed to have the same length. The hexagonal member 3 is
Adjacent to three pentagon members 2 ... Three hexagon members 3 ...
Next to each other. In the hexagonal member 3, three sides corresponding to each one side of the three adjacent pentagonal members 2 and three sides corresponding to each one side of the three adjacent hexagonal members 3 are alternately arranged. . Therefore, among the six sides of the hexagonal member 3, three sides are equal to the lengths of the corresponding sides of the adjacent hexagonal members 3, and the other three sides are, as described above, of the pentagonal member 2. The sides are formed to have the same length. These two
The three sides of the set may have the same length or different lengths. It should be noted that if the six sides of the hexagonal member 3 and the five sides of the pentagonal member 2 are all equal in length, in addition to the advantage of using two types of ceiling members, the use of the sides of the hexagonal member 3 ( That is, there is also an advantage that it is not necessary to distinguish between the side corresponding to the side of the hexagonal member 3 and the side corresponding to the side of the pentagonal member 2), which is convenient and does not require any trouble during construction.

The pentagonal member 2 and the hexagonal member 3 are arranged so as to divide the inner surface of the spherical surface into the pentagon and the hexagon. Therefore, each side of the pentagonal member 2 and the hexagonal member 3 is not limited to a straight line.

In order to construct the spherical ceiling material according to the present invention, for example, a method of attaching it to a spherical base material, a bar material (steel frame)
The method of attaching to the frame for the spherical ceiling assembled in 1. is used.

The spherical ceiling using the spherical ceiling material according to the present invention can be provided with a top light (skylight) 11 or a lighting fixture on the top thereof. In that case, top light
The spherical ceiling material around the lower side of 11 can be processed into an appropriate shape. The spherical ceiling does not have to be hemispherical, and may be larger than the hemisphere or smaller than the hemisphere. Top light 11 has louvers as needed
You may install 12 etc. and adjust the sunshine.

The shapes and arrangements of the pentagonal member 2 and the hexagonal member 3 may deviate from those described above, as a matter of course, at the parting of the spherical ceiling or the installation location of the top light, the lighting fixture, or the like.

The spherical ceiling material according to the present invention is used, for example, as a ceiling in a hotel lobby or a gymnasium, and an approximately spherical spherical ceiling having a smoothly connected surface with no unevenness due to a thrust or a gap can be obtained.

The spherical ceiling material according to the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the case where the spherical ceiling material is a ceiling material for top-sticking has been described as an example, but a ceiling material other than the top-sticking material such as a base may be used.

[Effect of device]

Since the spherical ceiling material according to the present invention is as described above, the number of types of ceiling members is small, and an approximately spherical spherical ceiling consisting of smoothly connected surfaces without unevenness due to pushing up or gaps is used. Obtainable.
