Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Field of Use The present invention provides a jig for positioning tiles between tiles, which was conventionally required, especially when aligning and firing Manju tiles and snow protection tiles that have sag. The present invention relates to a method for firing roof tiles in an aligned manner so that they can be fired without using anything.

Conventional technology Traditionally, tiles were fired by passing a firing cart through a tunnel furnace, in order to prevent adjacent tiles from coming into contact with each other and to enable uniform heating of each tile. As a method of alignment, support pins may be interposed between the tiles, or side plates made of heat-resistant metal, each having a plurality of notches into which the tiles are fitted, arranged side by side upwards, may be arranged at predetermined intervals using connecting members. It is known that they are connected in one piece, but especially when firing Manju tiles and snowstop tiles that have sag, supporting metal fittings such as the support pins and side plates mentioned above are always required 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 solves the problem by fitting the concave portions and convex portions formed on the back side of the Manju tile or snow stopper tile with sag into each other, and also by shifting the vertical axis to the center of the back side. The purpose is to stably align and fire the Manju tiles and the snow protection tiles by sandwiching the protruding portions formed by the roof tiles.

[Structure of the invention]

Means for Solving the Problems In view of the above problems, the present invention forms 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. The hangings of the Manju tiles are shifted so that they stand up vertically, their back surfaces are brought into contact with each other, and the upper concave and convex portions fit each other so that the Manju tiles can be aligned without using any jig between them. A method for aligning and firing roof tiles, and forming protrusions of approximately the same shape by shifting the vertical axis at the center of the back side of two Manju tiles having sag, and making the sag of two Manju tiles horizontally. To provide a method for arranging and firing tiles that are made to stand up vertically by shifting their positions, bring their back parts into contact with each other, and are sandwiched between the convex parts, thereby aligning the Manju tiles without using any jig. This is an attempt to overcome the above 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. to fit each of the concave and convex parts,
In addition, by sandwiching the convex portions formed in the center of the back surface in approximately the same shape with the vertical axes shifted, it is possible to stably align Manju tiles and snow protection tiles with sag, and to make it possible to shake the firing cart. The purpose is to align and fire the materials without causing any positional deviation even when the materials are moved.

Embodiment Hereinafter, an embodiment of the present invention will be described 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 to be 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.

FIG. 2 shows a second invention, in which convex portions 7 and 8 of approximately the same shape are formed protrudingly in the center of the back surface 4 of the Manju tile 1 having the tomoe 2 and the sag 3, with the vertical axis shifted. The convex portions 7 and 8 have an interval X between the upper and lower portions as in the first invention.

Next, to explain the operation of the method for arranging and firing tiles according to the present invention, the tiles are fired by standing them upright on a shelf board placed on a firing cart at regular intervals, and passing them through a tunnel furnace. In 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 tile and the snow prevention tile correspond to the hanging 2 of the two Manju tiles 1 and 1a. , 2a are shifted in the left-right direction to stand up vertically, and the back surfaces 4 and 4a are brought into contact with each other, so that the recess 5 and the projection 6a, and the projection 6 and the recess 5a are fitted, respectively. Manju tiles 1 and 1a have the maximum bulge on the back surface by sandwiching convex portions 7, 8 and 7a, 8a formed protrudingly from the center of the back surface 4 of the Ju-gawara and snow prevention tiles with their vertical axes shifted. The two parts are brought into contact with each other so that the positions of both are stably regulated, and the crosspiece parts 9, 9 of Manju tiles and snow stop tiles
In combination with the fact that the tiles themselves are in an upright position in a, the two tiles are firmly supported and stabilized.

〔Effect of the invention〕

In short, the present invention provides a recess 5 on the same line as the center of the back surface 4 of the Manju roof tile 1 having the sag 3, a slight distance X from the recess 5, and the recess 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 with the recesses 5, 5a,
The convex parts 6 and 6a are fitted together so that they are aligned without using any jig between the Manju tiles, and similarly, the center of the back surface 4 is arranged between the Manju tiles without using any jig. The projections 7 and 8 of substantially the same shape are formed in the upper and lower axes with their vertical axes shifted, and the hanging portions 3 and 3a of the two Manju tiles 1 and 1a are shifted in the left and right direction so that they stand vertically. Since the back surfaces 4 and 4a are brought into contact with each other and the protrusions 7 and 8 are sandwiched between each other, the Manju tile can be placed on a shelf board placed on a baking cart that is passed through a tunnel furnace.
When standing up and arranging the snow prevention tiles, support metal fittings were always provided between the Manju tiles and the snow prevention tiles, but according to the present invention, two Manju tiles, the snow prevention tiles 1 and 1
Shift the positions of the sag 3, 3a in the left-right direction to stand up vertically, and bring the back surfaces 4, 4a into contact with each other to fit the protrusion 6 into the recess 5a and the protrusion 6a into the recess 5, respectively. Therefore, the Manju tiles 1 and 1a, which are stably placed upright on the shelves at the crosspieces 9 and 9a, can be fitted without using any jig between them by the top fitting method, and the back surfaces 4 and 4a Together with the fact that the tiles are in contact with each other, they are firmly erected and lined up, and even if the firing cart is moved through the tunnel furnace, the Manju tiles will not come out of the fitted state even if there is vibration or rocking. They are stably aligned without being bent, and are provided in a state suitable for firing.

In the present invention, even if the concave portion 5, the convex portion 6, and the concave portions 7 and 8 are not formed in a state where they are properly fitted and sandwiched, the vibration and rocking of the firing cart will cause the fitted state and It is sufficient that the sandwiching state can be maintained, and if the height of the projections 6, 7, 8 is increased, one side of the crosspieces 9, 9a will be in solid contact with the shelf board when placed on the shelf board. The crosspieces 9, 9a can be made to stand up with only the corners in contact without being in contact with each other, and even during glazing, the crosspieces 9, 9a
Its practical effects are enormous, such as being able to carry out the process effectively.
