Abstract

PURPOSE:To simply and certainly perform dividing work and bonding execution by dividing an almost flat base plate on the basis of a plurality of lines linearly extending on the respective diagonal lines of a regular polygon equal to or more than a square containing the part to be finely divided of a picture pattern on said part. CONSTITUTION:An original picture pattern is prepared and a landscape having trees 3, 3' magnified in the same way as principal parts is drawn on the surface of a base plate 2. Since the trees 3, 3' are principal parts, on the basis of a circle 4 having a size containing the greater part of said principal parts, a pentagon 5 inscribed in the circle 4 is used with respect to one tree 3. Next, supposing respective regular pentagons 5, 5', ones drawing diagonal lines on the pentagons are assumed. These diagonal lines 6 are dividing lines and printed on a slide. The dividing lines 8 are projected on the base plate 2 using the slide and the base plate 2 is cut according to the dividing lines. The base plate 2 is cut along the projected dividing lines 6.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing a ceramic mural.

[Conventional technology]

Recently, ceramic murals have been put up on the walls of hotel lobbies and station premises, giving viewers a sense of excitement and peace of mind.

This ceramic wall painting is made by rolling out the clay into a single, almost flat plate on a workbench so that it has a certain planar shape, and then applying the desired pattern on the surface of the clay in an uneven pattern. It is manufactured through a process of dividing the clay into multiple parts and a firing process.

[Problem that the invention attempts to solve]

However, since the above-mentioned division was done entirely according to the author's intention, the division lines were at different angles, and therefore there was no reference line, so cutting work for division and firing the product pieces were done on the target surface. The pasting was based on the dividing line of 0 sections, which was time-consuming and lacking in certainty, so when looking at later ceramic murals, the sense of stability was somewhat lacking. Due to the lack of a standard structure, the creator had to create everything by hand, which was an obstacle to creating many good works.

This invention was made to solve these problems, and its objectives are to make the dividing work and pasting work extremely simple and reliable, and to ensure that the resulting ceramic wall painting is stable. A feeling comes out. There is no need for an expert to do much work, and even an apprentice can perform cutting, dividing, and pasting. [Means for Solving the Problem] In order to solve the above problem, this invention An original plate is prepared by rolling out a piece of clay into a substantially flat plate, and a desired pattern is applied to the surface of the original plate in an uneven manner. A method for producing a ceramic wall painting through the step of dividing, at least, by passing through each diagonal of a regular polygon of square or larger size that includes the portion of the pictorial tank that is to be divided into smaller pieces. It is characterized by a process in which a substantially flat original plate is divided based on a plurality of linearly extending lines.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

FIG. 1 shows a ceramic wall painting completed by pasting fired ceramic pieces according to the order code, and FIGS. 2 and 3 show the procedure for producing a piece, which is a unit of this ceramic wall painting.

First, an original drawing sheet, which is a smaller version of the ceramic mural, is prepared, and the artist draws the desired original drawing pattern on this sheet.
Next, as shown in FIG. 2, work begins on the workbench 1. First, prepare clay on a workbench 1 that is larger than a ceramic mural, and spread this clay flat on the workbench 1 to create the original plate 2. In this case, the original plate 2 is in the shape of a horizontally long rectangle. ing. Prepare the original picture design drawn earlier, and draw a similar enlarged picture tank on the surface of the original plate 2 based on it. You can also paint it in advance.

For example, if this picture tank is a tree 3 as shown in Figure 3,
Assume that it is a landscape painting having 3' as the main part.

A dividing line is drawn on the original plate 2 as follows.

Since the trees 3 and 3' are the main parts, for one of them 3, a regular pentagon 5 is used, which is inscribed in a circle 4 having a size that includes most of the same part. This regular pentagon 5 is assumed to be in a normal position, that is, its base is parallel to the base of the original plate 2 (it does not necessarily have to be parallel).

On the other hand, 3'' is also a regular pentagon of 5 degrees, which is inscribed in a circle 4'' that passes through the center of the inner 4.

Then, when each regular pentagon 5, 5'- is assumed, a diagonal line 6- is drawn on each of them.

These diagonal lines 6 (dividing lines) are determined, and once these dividing lines 6 are decided, print these dividing lines 6 on slides, for example. Then, the dividing lines 6 are projected onto the original plate 2. The original plate 2 is cut according to this.

The other tree 3' is also divided using the same projection method.

Projected division! 16-(,: The original plate 2 is cut along the line to become a pottery shard. This pottery shard is numbered in sequence on the back so that its position can be clearly identified. At this point, the pottery pieces are painted and then placed in the kiln to be fired.

The ceramic pieces 7-- thus completed are as shown in FIG. 1, and the ceramic pieces 7-- are pasted on the wall 8 according to the order numbers mentioned above.

In addition, the dividing line is made for the main part of the pictorial tank like tree 3.3', but if the dividing line is not enough around the pictorial tank, supplementary dividing line 9...- should also be added. Do it like this. Further, as shown in FIG. 4, the wall 8 is marked with a sequential code corresponding to each ceramic piece 7 so that the installation can be carried out efficiently.

In the completed ceramic wall 100, the dividing lines 6- are parallel, so many parallelograms are formed, and the 0 dividing line, where the sides of the parallelograms are oriented diagonally, is parallel, so the original When cutting or pasting ceramic pieces on a wall, the 0 division line becomes very simple and forms a parallelogram, giving a sense of stability. Many of the pottery pieces 7 are triangular within each parallelogram, and these triangles are
As shown in Figure 5, based on l, which is the diagonal when assuming a square with ratio l:1, we form a triangle A with 5 as the base, 1 as the vertical side, and 5 as the hypotenuse. Triangle B has a base of 1, the hypotenuse is 5, a triangle C has a base of 5, a length of 1, and a hypotenuse of J, and a triangle B has a base of 5, a length of 1, and a hypotenuse of J. It has become. These triangles are based on the so-called golden section, and as a result, the presence of many such triangles in ceramic murals appeals to the viewer's sense of art. Also, the 6th
As shown in the figure, if the pottery shard is square, the way it catches fire will be constant, and when it is attached to a wall, the gaps between the corners of the pottery shard will be even, which will tend to impair the artistry.
As shown in the figure, when the pottery pieces are triangular, the way the fire enters the corner is different, and the gaps between them when attached to the wall are also different, creating an artistic effect. It will become. Moreover, as shown in Figure 8, if the ceramic piece is square, the weight is likely to be applied to the corners (black dots), but if it is a triangular piece, a component force will act on it, making it difficult for the weight to be applied to the piece. is less likely to break. Furthermore, since there are many diagonal dividing lines, the standard 0-dividing method makes it easy for dirt to fall off and cleaning.・Able to do split work.

In the above embodiment, a method of projecting by sliding was adopted, but for example, regular pentagonal frames of different sizes may be used, and a plurality of straight bar-shaped dividing members passing diagonally on the bottom side of the open frame may be used. The tool may be provided and placed on the original with the dividing member facing downward, and the original may be cut along the dividing member.

Figures 9 and 10 show additional embodiments. The ceramic piece 10 of this embodiment allows the ceramic piece 10 to be stuck to the wall 11 more stably. That is, the inside of the potsherd 1O is removed from the back to create a space 12, but the center of gravity of this space 12 is now above the potsherd 10, and the center of gravity of the whole potsherd is downward. Therefore, when the ceramic piece 1O is attached to the wall 11, it is stable so that it leans against the wall 11 and stands on its own.The ceramic piece 1O is attached with a wire 13 and an anchor bolt 14. It looks like this.

FIG. 11 shows another additional embodiment.

This shows a structure in which one of the 20-Φ pottery pieces pasted on the wall is later removed and other ornaments are inserted into this space. An example is a vase.

〔Effect of the invention〕

The present invention is as described above, and therefore, the dividing work and pasting work are extremely simple and reliable, and the resulting ceramic wall painting has a sense of stability.

There is no need for the P-related person to do much work, and even an apprentice can do the cutting, dividing, and pasting.
