The sagger (H which is shown in Japanese Utility Model Publication No. 6-33000)
A type of sagger is used, and it is common to place tiles inside and stack them in multiple stages for flat firing, or to incline the H-shaped sagger about 55 degrees and place the tiles inside to perform an inclined firing. It was However, in such a conventional method, the weight of the sagger is larger than the weight of the roof tile to be fired, for example, 3.5: 6. Therefore, the heat capacity of the bowl is larger than the heat capacity of the roof tile, and there is a problem that the heat efficiency (fuel consumption) is poor.

As disclosed in Japanese Patent Publication No. JP-A-2003-264, there is also used a roof tile baking material in which a large number of comb-teeth-shaped supporting pieces for supporting roof tiles are formed on both side walls of a heat-resistant metal plate having a U-shaped cross section. However, since this tile firing shelf material is used by pressing it on the upper surface of an ordinary refractory shelf board, its overall heat capacity is still large, although not as great as when using a sagger, After all, there was a problem that the thermal efficiency was poor, and that it was a metal and thus had a short life due to high temperature oxidation.

る。The shelving material for roof tile firing of the present invention has a light weight pin erected on the upper surface of the shelf plate, so that it has a small heat capacity and can be fired with high thermal efficiency. Further, the roof tiles for roof tile firing of the present invention, since the roof tiles are fired while being held at an angle of 70 to 90 degrees with respect to the shelf plate by the pins, the roof tiles are less deformed during firing as compared with the inclined firing, and There is an advantage that the number of sheets that can be fired per area is larger than that of the conventional method, compared with the case of flat firing. In addition, if the roof tile is inclined in a certain direction by providing the roof tile inclined portion on the upper surface of the shelf plate between the pins in the front-rear direction, there is an advantage that the glaze surface can be prevented from adhering to the pin.

A number of refractory pins erected in. The shelf 1 is made of cordierite, alumina, alumina / silica,
The pin 2 is made of a refractory material such as mullite, and the pin 2 is made of, for example, alumina porcelain or mullite porcelain because strength is required. The pin 2 can also be made of refractory metal.

定しておくものとする。In this embodiment, square holes 6 that are slightly inclined so that the upper surface is wide are formed at regular intervals on the left and right sides of the shelf 1, and the lower ends of the pins 2 having a square cross section are formed in the square holes 6. Has been inserted. The pin 2 may have a rod shape such as a cylinder or a prism, but it is preferable that the contact surface with the roof tile is a flat surface. The thickness of the pin 2 is not particularly limited, but the upper end is preferably thin. Pin 2 in the embodiment
The angle formed by the side surface of the with respect to the upper surface of the shelf board 1 is about 86 degrees. Therefore, when the roof tile 10 is erected so as to be in close contact with the side surface of the pin 2, the angle formed by the roof tile 10 with respect to the upper surface of the shelf plate 1 is 86 degrees. Further, since the roof tile 10 is often supplied by an automatic machine, there is a possibility that the roof tile 10 may be displaced until the lower end of the roof tile 10 comes into contact with the adjacent pin 2 in the front-rear direction, as shown in FIG. However, even in this case, the distance between the pins 2 and 2 in the front-back direction is set so that the angle of the roof tile 10 does not become less than 70 degrees.

The number of fired tiles 10 can be increased. In addition,
In order to prevent the roof tile 10 from being deformed during firing, the pin 2 needs to have a certain length, which is at least ⅓ or more, preferably ½ or more of the height of the roof tile 10. In the example of FIG. 1, the length of the pin 2 is 3/5 of the height of the roof tile 10.

However, as described above, since the roof tile 10 is often supplied by an automatic machine, if the top surface of the shelf board 1 is flat, the roof tile 10 may be inclined toward the glaze layer 11. So shelf 1
It is preferable to provide a roof tile inclined portion 3 for inclining the roof tile 10 in a fixed direction in a portion between the pins 2 in the front-rear direction on the upper surface of the roof tile 10. The roof tile inclined portion 3 may be provided integrally with the shelf board 1, may be formed separately from the shelf board 1, and may be placed in a state of being joined between the pins 2 and 2 in the front-rear direction, or may be provided simply in a state of being placed. May be. In the example of FIG. 4, the roof tile inclined portion 3 is a ridge, and the bottom surface of the roof tile 10 placed thereon is pushed up to incline, but the top surface of the shelf board 1 may be an inclined surface as shown in FIG. Further, the roof tile inclined portion 3 may be provided in a spot on the peripheral portion of the pin 2 or may be provided over the entire width direction.

In the first embodiment, the pair of pins 2 and 2 are erected in pairs on the left and right of the shelf board 1 to stably support both the left and right sides of the roof tile 10. In the embodiment, these two pins are integrated. That is, the left and right upright portions 4, 4 are connected by the horizontal portions 5, 5 to form an integrated pin 2. When the independent pin 2 is used as in the first embodiment, the roof tile 10 may be supported by only one pin 2 when the left and right pins 2, 2 are displaced. On the other hand, according to the second embodiment, since the upright portions 4 and 4 on both sides are not likely to be displaced, the roof tile 10 can always be stably supported on both left and right sides. Also in this second embodiment, the roof tile 1 is provided with the roof tile inclined portion 3.

とができる。As is apparent from the above description of the embodiments, the roof tile firing shelf material of the present invention is one in which a large number of pins are erected on the upper surface of the shelf plate, and the heat capacity of the pins is extremely small. Therefore, flat roof tiles and other flat roof tiles can be fired with good thermal efficiency. In addition, the pin spacing is such that the roof tiles can be held at an angle of 70 to 90 degrees with respect to the shelf plate, so it is possible to prevent the roof tiles from deforming during firing, and to reduce the number of fired tiles per area in the past. Can be increased more than.
