Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The present invention is particularly useful for aligning and firing Manju tiles and snow-stop tiles that have sagging tiles, and is designed to provide a jig for positioning the tiles between tiles, which was previously required. This relates to a Manju tile that was used for firing without any use.

Conventional technology Conventionally, tiles are fired by passing a firing cart through a tunnel furnace, which prevents adjacent tiles from coming into contact with each other and enables uniform heating of each tiles. In order to align the roof tiles, support pins may be interposed between the roof tiles, or side plates made of heat-resistant metal with multiple notches into which the roof tiles are fitted may be placed in parallel at predetermined intervals as connecting members. However, especially when firing Manju tiles and snow protection tiles that have sag, it is necessary to use supporting metal fittings such as the support pins or side plates between the tiles. Without such supporting metal fittings, it would be impossible to stably align and fire tiles.

Problems to be Solved by the Invention The present invention stabilizes the Manto tiles and snow prevention tiles by fitting the recesses and protrusions formed on the back side of the Manto tiles and snow prevention tiles, which have sag, into each other. The purpose is to perform proper alignment and firing.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention has been developed by forming a concave portion and a convex portion of a size that can fit into the concave portion on the same line at the center of the back side of a Manju tile having a sag. It is an object of this invention to provide a roof tile to eliminate the above-mentioned drawbacks.

Function The present invention has a concave portion formed on the same line at the center of the back surface, and a convex portion large enough to fit into the concave portion, so that the back surfaces of two Manju tiles are brought into contact with each other. By fitting each of the concave portions and convex portions with each other, Manju tiles and snow protection tiles with sag can be stably aligned, and aligned and fired without any displacement even when the firing cart swings. This is what we do.

Embodiment An embodiment of the present invention will be described below based on the drawings. 1 is a Manju tile having a tomoe 2 and a hanging 3, and a recess 5 on the same line at the center of the back surface 4 of the Manju tile, and the recess. 5, and a protruding portion 6 is formed so as to be able to fit into the recessed portion 5.

The depth of the concave portion 5 is made slightly shallower than the protrusion of the convex portion 6, and the Manju tile 1 is integrally molded and tested using a known molding method.

Next, to explain the function of the Manju Kawara according to the present invention, the firing of the tiles is carried out by leaning the tiles upright on a shelf placed on a firing cart at regular intervals and passing them through a tunnel furnace. To conclude, in the case of the present invention, the concave portion 5 and the convex portion 6 formed on the same line at the center of the back surface 4 of the Manju tiles and the snow prevention tiles are the sagging portions 2 and 2a of the two Manju tiles 1 and 1a. By shifting the position in the left-right direction and standing vertically, and bringing the back surfaces 4 and 4a into contact with each other, and fitting the concave part 5 and the convex part 6a, and the convex part 6 and the concave part 5a, respectively, the Manju tile 1 , 1a, the maximum bulging part on the back side is in contact with each other to stably regulate the position of both, and the tile itself is also in an upright state at the crosspieces 9 and 9a of the Manju tile and snow stop tile. Together with this, the two roof tiles are firmly supported and stabilized.

[Effect of idea]

In short, the present invention has a concave portion 5 on the same line as the center of the back surface 4 of the Manju tile 1 having the sag 3, and has a slight interval X from the concave portion 5, and the concave portion 5
A convex portion 6 of a size that can be fitted is formed, and the hanging portions 3, 3aa of the two Manju tiles 1, 1a are shifted in the left and right direction so that they stand up vertically and the back surfaces 4, 4a are connected to each other. In contact, the recesses 5, 5a,
Since the protrusions 6 and 6a are fitted together and aligned without using any jig between the Manju tiles, there is no need to worry about any damage to the shelves placed on the baking cart that passes through the tunnel furnace. When standing up and arranging ten tiles and snow prevention tiles, supporting metal fittings were always provided between the Manju tiles and snow prevention tiles, but according to the present invention, two Manju tiles and snow prevention tiles were installed. The hanging portions 3, 3a of the tiles 1, 1a are shifted in the left and right directions to stand up vertically, and the back surfaces 4, 4a are brought into contact with each other, and the protrusion 6 is fitted into the recess 5a, and the protrusion 6a is fitted into the recess 5, respectively. By fitting together, the Manju tiles 1 and 1a, which are stably placed upright on the shelves at the crosspieces 9 and 9a, can be assembled without using any jig between them by the top fitting method.
In addition, since the back surfaces 4 and 4a are in contact with each other, the tiles are firmly erected and lined up, and the Manju tiles do not touch each other even when the firing cart is shaken or shaken as it passes through the tunnel furnace. They are stably aligned without deviating from the fitted state, and are provided in a state suitable for firing.

In addition, in the case of the present invention, if the protrusion height of the convex portion 6 is increased, when placed on a shelf board, one side of the crosspieces 9, 9a does not come in solid contact with the shelf board, but only the corner part contacts the shelf board. The practical effects of this are enormous, such as being able to stand upright and effectively forming the crosspieces 9, 9a during glazing.
