され炉内で倒壊する事故が発生していた。(Prior Art) Although various types of shelf boards for firing roof tiles have been conventionally used for firing roof tiles, when firing Noshi roof tiles, in the case of glazed tiles, the glaze on the surface of the tile base material is welded to the shelf board. In the case of smoked roof tiles, the smoldering gas may not penetrate into the lower surface of the roof tile base material that is in contact with the shelf plate, and smoked defects may occur. Therefore, a pair of recessed grooves or ridges are formed on the surface of the shelf board body, a pair of spacers made of heat-resistant metal rods or refractory rods are placed on these portions, and the tile base is arranged on the upper surface of the spacers. It has been devised. However, since the cross-sectional shape of the roof tile is different for each company, and the center of gravity position is also changed accordingly, the preferable spacer interval varies from company to company. Therefore, there is a problem that it is not possible to meet the demands of each company unless a very large number of types of roof tile baking shelves are stored in stock. In addition, even with the same type of roof tile, the squareness of the end face of the roof tile body formed by the abrasion of the die of the clay kneader or the wear of the molding die may change, which impairs the self-supporting property of the roof tile body. May be In order to deal with this, it is desirable to change the spacer spacing, but it is practically impossible to change the shelf plate each time, and there is an accident in which it burns in an unstable state and collapses in the furnace.

あった。Furthermore, since the conventional shelf plate has only a pair of concave grooves, the tiles are fired by arranging the spacers in a line inside each concave groove. If the tile base material is pushed up or the interval between the end portions of the spacers is excessively widened in order to avoid this, there is a case where the tile base material falls into the interior of the tile base material and causes "behavior failure".

されることとなる。FIG. 1 is a view showing an embodiment of the first invention, (1) is a shelf main body made of ceramics such as cordierite and mullite which has heat resistance around 1200 ° C. Recessed grooves (3a) to (3c) for mounting the spacer (2) on both sides of the line and recessed grooves (4a) to (4c) are formed. Since the spacer (2) is usually a round bar made of heat-resistant metal or ceramics having a diameter of 8 to 12 mm and a length of about 400 to 700 mm as shown in FIG. 2, the concave grooves (3), (4) ) Shall have a cross-sectional shape that corresponds to the dimensions of this spacer (2). Also, due to the size of general roof tiles,
The distance between the groove (3a) and the groove (4a) is about 50 mm, and the groove (3c) and the groove (4
The distance from c) may be about 150 mm, and therefore the groove pitch is appropriately determined within the range of about 10 to 20 mm depending on the number of grooves.

ある。When the roof tile for firing roof tiles configured as described above is used for firing roof tiles, spacers (2) are placed in the concave grooves (3a) and (4a), respectively, and the roof tile substrate is arranged on the upper surface of the roof tiles for firing. In addition, when firing a large roof tile, the spacers (2) may be placed in the concave grooves (3c) and (4c) and fired. Other groove
Since many combinations of (3a) and concave groove (4b), concave groove (3a) and concave groove (4c), and the like can be taken, they can be commonly used for roof tiles of various sizes and cross-sectional shapes. Furthermore, even for tile tiles whose squareness has changed and their independence has been impaired, spacers
It is possible to easily deal with this by simply changing the position of (2).

(2) are arranged alternately, but at this time, the spacers (2) and (2) are arranged so that the ends thereof are slightly overlapped.
このようにスペーサ(2)、(2)を配置すれば従来のように

かえない。If the spacers (2) and (2) are arranged in this way, there is no fear that the tile base material will fall from the joint portion of the spacer (2) as in the conventional case, and each spacer (2) has a groove (3), Since it can be freely expanded and contracted inside (4), the tile roof material at the joint portion is not pushed up by thermal expansion, and the "behavior" of the tile can be prevented. Although the round bar-shaped spacer (2) is used in the above embodiments, the cross-sectional shape of the spacer may be a triangle such as a triangle or a quadrangle.
