[Detailed description of the device]

[0001]

[Industrial application] This invention is used in the drying and firing process of roof tiles such as round roof tiles, fusuma roof tiles, eaves roof tiles, valley round roof tiles, sleeve round roof tiles, etc. The present invention relates to a firing interval holder.

[0002]

Conventionally, the time of drying and firing of the concave roof tile or Fushimi between tiles, two triangular steel bar c disposed parallel to the on carriage as shown in Fig. 6, c (or round bar rectangular bar, etc.) or put at intervals the concave roof tile a or Fukukankawara b over, or FIG. 7 a, it is commonly done be loaded on the shelf bricks d as B.

[0003]

As shown in FIG. 6 , when the round tile a or the Fusuma tile b is placed on the triangular steel rods c, c and the firing process is performed, the tiles and the triangular steel rods are applied by the glaze of the tiles. Sintering occurs at the contact point with c, and the sintered part is peeled off to take out the roof tile, so that a lot of extraneous products are generated due to peeling scratches and the yield is reduced. Further, since the round roof tile a and the Fusuma roof tile b are placed on the triangular steel rods c, c in a flat lying position as shown in FIG. 6 , a relatively large occupied space is required, and the roof tiles that can be placed are It has the drawbacks of low number of sheets and poor production efficiency.

[0004] Figure 7 A, concave roof tile a like B, in the case of schemes put Fukukankawara b on the shelf brick d, since the back surface that is not coated with the glaze is supported by ledge bricks d, glaze There is no problem of yield reduction due to peeling. However, since the roof tiles are still placed in a laid-down posture, there are disadvantages that the number of roof tiles that can be placed is small and the production efficiency is low, which is a problem to be solved.
