Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a baking stand used for baking curved tiles, and more particularly to a technical means for performing good baking.

(Problems to be Solved by Conventional Techniques and Inventions) As shown in FIG. 4, when the curved tile 100 is fired, it is usually placed on a baking table having a mountain-shaped support table 102 having a predetermined thickness. Place and bake.

By the way, in this baking stand, since the thickness of the top of the support stand 102 is thicker than that of the other portions, the cooling rate at the time of firing and cooling the tile becomes slower than the other portions. The same is true for the tiles themselves, so the support base 10
When the top of the tile 100 is stacked on the top of No. 2 and fired, there is a problem that the tile 100 has a cut 104 in the form as shown in the figure due to the difference in cooling rate between the top and other portions during cooling.

(Means for Solving the Problem) The present invention has been made to solve such a problem, and the gist thereof is to provide a baking stand for baking which has a mountain-shaped support base for mounting curved tiles. , The top of the support base is cut entirely or at regular intervals along the ridgeline of the mountain to a portion below the apex by a predetermined size, and the support base is It is to have a hollow structure and at least the top of the support base, on which the bent tile is placed, to have a smooth surface and a constant wall thickness.

(Operation and Effect of Invention) As described above, according to the present invention, the mountain-shaped support base has an internal hollow structure and the tile mounting portion excluding the top has a smooth surface and a constant wall thickness. According to the present invention, the cooling rate of the portion other than the top portion of the support base can be made uniform at each portion, and the top portion is cut off so that the cooling rate of the other top portion can be reduced. Can be equalized with that of the pieces.

Therefore, in the cooling process at the time of firing the tile, it is possible to prevent the breakage of the tile due to the difference in the cooling rate.

In the present invention, the apex may be entirely cut along the ridgeline of the mountain, but it is preferable that the apex be cut off at regular intervals along the ridgeline of the mountain. If the top of the mountain-shaped portion is cut off entirely,
Occasionally insufficient support for the backside of the top of the curved tile may cause the tile to deform in an angle opening direction during firing. On the other hand, if the top portion is cut out at regular intervals, the back surface of the top portion of the tile is favorably supported and there is no fear of causing such a problem.

(Example) Next, the Example of this invention is described in detail based on drawing.

In FIG. 1, 10 is a refractory baking platform, which has a mountain-shaped support platform 12. As shown in FIGS. 2 and 3, the support base 12 is formed with a constant wall thickness on two sides of the support base 12 having an internal hollow structure and a triangular cross section except for the top. At the same time, the surface is a smooth surface without irregularities, and over the entire range along the ridgeline of the mountain at the top of the peak, a cutting portion 14 of a form cut from the apex to a certain size lower side is provided at predetermined intervals. Has been formed.

Therefore, when bending tiles are placed on the baking table 10 and fired, the cooling rate at the top of the mountain-shaped portion becomes almost equal to that of the other portions, and the tiles are cut due to the difference in their cooling rates. Absent.

Further, in this baking stand 10, since the top and back surfaces of the tiles are reliably supported by the portions other than the cutout portion 14, there is no problem that the tiles are deformed in an angle opening direction during firing.

By the way, when the tiles were fired using the baking stand 10 of this example, it was confirmed that the tile breakage as described above occurred with a probability of 10 to 20%, but it was reduced to almost 0.

It should be noted that the above-mentioned deformation of tiles is particularly likely to occur in the case of large tiles, and therefore, when firing small tiles,
It is also possible that the top of the mountain-shaped portion is entirely cut along the ridgeline.

Further, the above-illustrated baking stand 10 is merely an example, and the present invention can be applied to baking stands of other forms, etc., and various changes can be made based on the knowledge of those skilled in the art without departing from the spirit of the invention. It can be configured in a modified form.
