2. Description of the Related Art Refractory plates are used for firing products using glazes such as mosaic tiles. In order to bake such a refractory plate, as shown in FIG. 4, a method is adopted in which a shelf plate 12 is passed over a trolley 11 in two or three steps, and a refractory plate 14 is placed vertically thereon. Improves the efficiency of kiln filling. However, in the case of such a vertical installation, to prevent the refractory plate 14 from falling down, bricks are stacked on the front and rear sides of the cart 11,
Alternatively, it is necessary to build a strong wall 15 that can withstand the weight of the refractory plate 14 on which the support is placed.

[0003] As a result, a shelf board 12 and a wall 15
And the weight of the kiln tools, etc., and the refractory plate to be fired
The ratio to the weight of 14 is about 3: 2, which is a kiln-filled configuration with low thermal efficiency during firing. Further, such a shelf plate 12 needs to be replaced because it is gradually deformed due to the weight of the refractory plate 14, but since it is integrated with the strong wall 15, the wall 15 is broken and then replaced. There is an irrational point that must be done.

The kiln tool thus constructed according to the present invention is used for vertically placing an object to be fired between columns 4, 4 erected near both ends of a shelf 1 and firing. The weight of a large number of objects to be fired is applied to the plate-shaped support 4.
Is inserted into the hole 2 of the shelf 1 and its outside is supported by the wedge 7, so that the weight of the object to be fired can be stably supported. When the whole is expanded by the heat during firing, the hole 2 also becomes large, but the wedge 7 falls by its own weight and fits deeper, so that the plate-shaped column 4 does not tilt.

The bending moment and thermal stress of the column 4 due to the weight of the material to be fired act on the inner surface of the hole 2 of the shelf 1 and the like. In the embodiment, the hole 2 is formed with a slit 3. Since the stress can be relieved, the shelf board 1 does not crack even if firing is repeated many times.

As described above, the kiln tool of the present invention enables the vertically sintering of the object to be fired by the combination of the relatively light shelf plate 1 and the columns 4, and the conventional kiln tool as shown in FIG. As compared with the structure, the overall weight can be significantly reduced, and the calorific value taken out of the kiln tool can be reduced, so that the thermal efficiency of firing can be improved. Further, since the kiln tool of the present invention does not need to support the weight of the object to be fired by the strong wall 15 unlike the related art, it is easy to replace the shelf plate 1 when it is deformed. In this case, there is also an advantage that the shelves 1 and the columns 4 can be easily separated by removing the wedges 7.
